abstract = "A series of three experiments has been performed to
test both the preference and accuracy of high
dynamic-range (HDR) rendering algorithms in digital
photography application. The goal was to develop a
methodology for testing a wide variety of previously
published tone-mapping algorithms for overall
preference and rendering accuracy. A number of
algorithms were chosen and evaluated first in a
paired-comparison experiment for overall image
preference. A rating-scale experiment was then designed
for further investigation of individual image
attributes that make up overall image preference. This
was designed to identify the correlations between image
attributes and the overall preference results obtained
from the first experiments. In a third experiment,
three real-world scenes with a diversity of dynamic
range and spatial configuration were designed and
captured to evaluate seven HDR rendering algorithms for
both of their preference and accuracy performance by
comparing the appearance of the physical scenes and the
corresponding tone-mapped images directly. In this
series of experiments, a modified Durand and Dorsey's
bilateral filter technique consistently performed well
for both preference and accuracy, suggesting that it is
a good candidate for a common algorithm that could be
included in future HDR algorithm testing evaluations.
The results of these experiments provide insight for
understanding of perceptual HDR image rendering and
should aid in design strategies for spatial processing
and tone mapping. The results indicate ways to improve
and design more robust rendering algorithms for general
HDR scenes in the future. Moreover, the purpose of this
research was not simply to find out the ``best''
algorithms, but rather to find a more general
psychophysical experiment based methodology to evaluate
HDR image-rendering algorithms. This paper provides an
overview of the many issues involved in an experimental
framework that can be used for these evaluations.",

ability to discriminate and identify finger joint-angle
positions using active motion. The PIP (proximal
interphalangeal) joint of the index finger was examined
in Exps. 1--3 and the MCP (metacarpophalangeal) joint
in Exps. 4--6. In Exp. 1, the just noticeable
difference (JND) of PIP joint-angle position was
measured when the MCP joint was either fully extended
or halfway bent. In Exp. 2, the JND of PIP joint-angle
position as a function of PIP joint-angle reference
position was measured when the PIP joint was almost
fully extended, halfway bent, or almost fully flexed.
In Exp. 3, the information transfer of PIP joint-angle
position was estimated with the MCP joint in a fully
extended position. In Exps. 4--6, the JND and the
information transfer of MCP joint-angle position were
studied with a similar experimental design. The results
show that the JNDs of the PIP joint-angle position were
roughly constant ($2.5^\circ$--$2.7^\circ$) independent
of the PIP joint-angle reference position or the MCP
joint-angle position used (Exps. 1 and 2). The JNDs of
the MCP joint-angle position, however, increased with
the flexion of both the PIP and MCP joints and ranged
from $1.7^\circ$ to $2.7^\circ$ (Exps. 4 and 5). The
information transfer of the PIP and MCP joint-angle
position were similar, indicating 3--4 perfectly
identifiable joint-angle positions for both joints
(Exps. 3 and 6). The results provide the basic data
needed for estimating, for example, the resolution of
fingertip position during active free motion. They are

behavior, we will need to understand its basic
components at an abstract level. One way to achieve
such an understanding would be to create a model of a
human that has a sufficient amount of complexity so as
to be capable of generating such behaviors. Recent
technological advances have been made that allow
progress to be made in this direction. Graphics models
that simulate extensive human capabilities can be used
as platforms from which to develop synthetic models of
visuomotor behavior. Currently, such models can capture
only a small portion of a full behavioral repertoire,
but for the behaviors that they do model, they can
describe complete visuomotor subsystems at a useful
level of detail. The value in doing so is that the
body's elaborate visuomotor structures greatly simplify
the specification of the abstract behaviors that guide
them. The net result is that, essentially, one is faced
with proposing an embodied ``operating system'' model
for picking the right set of abstract behaviors at each
instant. This paper outlines one such model. A
centerpiece of the model uses vision to aid the
behavior that has the most to gain from taking
environmental measurements. Preliminary tests of the
model against human performance in realistic VR
environments show that main features of the model show
up in human behavior.",

either physically locomoting to a new facing direction
or imagining moving. The latencies and errors were
generally worse after imagining locomoting and for
greater degrees of rotation in perspective; they did
not differ significantly across knowledge derived from
exploring the physical versus virtual environments. In
the second experiment, subjects were asked to imagine
simple rotations versus simple translations in
perspective. The errors and latencies indicated that
the to-be-imagined disparity was linearly related after
learning the physical and virtual environment. These
results demonstrate functional similarities in access
to knowledge of new perspective when it is learned by
exploring physical environments and virtual renderings

thermal display was developed based on a semi-infinite

evaluate the performance of the display. The first
experiment compared the ability of subjects' to
identify various materials, which were presented
physically or simulated with the thermal display. The
second experiment examined the capacity of subjects to
discriminate between a real and simulated material
based on thermal cues. In the third experiment, the
changes in skin temperature that occurred when making
contact with real and simulated materials were measured
to evaluate how these compare to theoretical
predictions. The results indicated that there was no
significant difference in material identification and
discrimination when subjects were presented with real
or simulated materials. The changes in skin temperature
were comparable for real and simulated materials and
were related to the contact coefficient of the material
palpated, consistent with the semi-infinite body model.
These findings suggest that a thermal display is
capable of facilitating object recognition when visual
cues are limited.",

computing images that are perceptually
indistinguishable from the real world they are
attempting to portray. Such a level of fidelity
requires that the physical processes of materials and
the behavior of light are accurately simulated. Most
computer graphics algorithms assume that light passes
freely between surfaces within an environment. However,
in many applications, we also need to take into account
how the light interacts with media, such as dust,
smoke, fog, etc., between the surfaces. The
computational requirements for calculating the
interaction of light with such participating media are
substantial. This process can take many hours and
rendering effort is often spent on computing parts of
the scene that may not be perceived by the viewer. In
this paper, we present a novel perceptual strategy for
physically based rendering of participating media. By
using a combination of a saliency map with our new
extinction map (X map), we can significantly reduce
rendering times for inhomogeneous media. The visual
quality of the resulting images is validated using two
objective difference metrics and a subjective
psychophysical experiment. Although the average pixel
errors of these metric are all less than 1\%, the
subjective validation indicates that the degradation in
quality still is noticeable for certain scenes. We thus
introduce and validate a novel light map (L map) that
accounts for salient features caused by multiple light
scattering around light sources.",

facial expressions are stylized using three common
techniques (brush, cartoon, and illustrative
stylization) and investigated using different
experimental measures. Going beyond the usual
questionnaire approach, these experiments compare the
techniques according to several criteria ranging from
subjective preference to task-dependent measures (such
as recognizability, intensity) allowing us to compare
behavioral and introspective approaches. The second set
of experiments use the same stylization techniques on
real-world video sequences in order to compare the
effect of stylization on natural and artificial

that our suprathreshold contrast sensitivity follows
the Weber Law and, hence, increases proportionally with
the increase in the mean local luminance. In this
paper, we effectively apply this fact to design a
contrast-enhancement method for images that improves
the local image contrast by controlling the local image
gradient with a single parameter. Unlike previous
methods, we achieve this without explicit segmentation
of the image, either in the spatial (multiscale) or
frequency (multiresolution) domain. We pose the
contrast enhancement as an optimization problem that
maximizes the average local contrast of an image
strictly constrained by a perceptual constraint derived
directly from the Weber Law. We then propose a greedy
heuristic, controlled by a single parameter, to
approximate this optimization problem.",

virtual environments to study judgments that
pedestrians make when deciding to cross a street. In
particular, we assess the ability of people to

Four experiments observing TTC judgments under various
conditions are described. We examine the effect of type
of vehicle, viewpoint, presentation mode, and TTC value
on TTC judgments. We find no significant effect of type
of vehicle or of viewpoint, extending prior work to
cover all views typically encountered by pedestrians.
Discrimination of short values for TTC judgments is
generally consistent with the literature, but
performance degrades significantly for long TTC values.
Finally, we find no significant difference between
judgments made in a desktop environment versus a
head-mounted display, indicating that tracking the
approaching vehicle with one's head does not aid
discrimination. In general, people appear to use
strategies similar to those that pedestrians use to
make real-world, street-crossing decisions.",

human vision that allows us to efficiently and rapidly

the processes underlying human scene categorization,

information. In this study, we present both
psychophysical and computational experiments that
investigate the role of local versus global image
information in scene categorization. In a first set of
human experiments, categorization performance is tested
when only local or only global image information is
present. Our results suggest that humans rely on local,
region-based information as much as on global,
configural information. In addition, humans seem to
integrate both types of information for intact scene
categorization. In a set of computational experiments,
human performance is compared to two state-of-the-art
computer vision approaches that have been shown to be
psychophysically plausible and that model either local
or global information. In addition to the influence of
local versus global information, in a second series of
experiments, we investigated the effect of color on the
categorization performance of both the human observers
and the computational model. Analysis of the human data
suggests that color is an additional channel of
perceptual information that leads to higher
categorization results at the expense of increased
reaction times in the intact condition. However, it
does not affect reaction times when only local
information is present. When color is removed, the
employed computational model follows the relative
performance decrease of human observers for each scene
category and can thus be seen as a perceptually
plausible model for human scene categorization based on
local image information.",

them to images in which distinct data dimensions are
mapped to distinct visual features, such as color, size
and orientation. Here, we consider visualizations in
which different data dimensions should receive equal
weight and attention. Many of the end-user tasks
performed on these images involve a form of visual
search. Often, it is simply assumed that features can
be judged independently of each other in such tasks.
However, there is evidence for perceptual dependencies
when simultaneously presenting multiple features. Such
dependencies could potentially affect information
visualizations that contain combinations of features
for encoding information and, thereby, bias subjects
into unequally weighting the relevance of different
data dimensions. We experimentally assess (1) the
presence of judgment dependencies in a visualization
task (searching for a target node in a node-link
diagram) and (2) how feature contrast relates to
salience. From a visualization point of view, our most
relevant findings are that (a) to equalize saliency
(and thus bottom-up weighting) of size and color, color
contrasts have to become very low. Moreover,
orientation is less suitable for representing
information that consists of a large range of data
values, because it does not show a clear relationship
between contrast and salience; (b) color and size are
features that can be used independently to represent
information, at least as far as the range of colors
that were used in our study are concerned; (c) the
concept of (static) feature salience hierarchies is
wrong; how salient a feature is compared to another is
not fixed, but a function of feature contrasts; (d)
final decisions appear to be as good an indicator of
perceptual performance as indicators based on measures
obtained from individual fixations. Eye tracking,
therefore, does not necessarily present a benefit for
user studies that aim at evaluating performance in
search tasks.",

using displays that provided a level of detail far
short of what the human visual system is capable of
resolving. Therefore, we undertook a graph
comprehension study using a very high resolution
stereoscopic display. In our first experiment, we
examined the effect of stereoscopic display, kinetic
depth, and using 3D tubes versus lines to display the
links. The results showed a much greater benefit for 3D
viewing than previous studies. For example, with both
motion and stereoscopic depth cues, unskilled observers
could see paths between nodes in 333 node graphs with
less than a 10\% error rate. Skilled observers could
see up to a 1000-node graph with less than a 10\% error
rate. This represented an order of magnitude increase
over 2D display. In our second experiment, we varied
both nodes and links to understand the constraints on
the number of links and the size of graph that can be
reliably traced. We found the difference between number
of links and number of nodes to best account for error
rates and suggest that this is evidence for a

graphics since the inception of the field. However, the
perception of visual realism is not a well-understood
process and is usually attributed to a combination of
visual cues and image features that are difficult to

problem is even more involved. The purpose of this
paper is to present a study based on eye tracking for
investigating the perception of visual realism of
static images with different visual qualities. The
eye-fixation clusters helped to define salient image
features corresponding to 3D surface details and light
transfer properties that attract observers' attention.
This enabled the definition and categorization of image
attributes affecting the perception of photorealism.
The dynamics of the visual behavior of different
observer groups were examined by analyzing saccadic eye
movements. We also demonstrated how the different image
categories used in the experiments were perceived with
varying degrees of visual realism. The results
presented can be used as a basis for investigating the
impact of individual image features on the perception
of visual realism. This study suggests that post-recall

accurate and the use of eye tracking provides an
effective way of determining relevant features that
affect visual realism, thus allowing for improved

tactile illusion engendered by straining the fingertip
skin tangentially in a progressive wave pattern

a sinusoidal surface sliding on a finger as well as the
field created by a tactile transducer array deforming
the fingerpad skin by lateral traction. We found that
the first field could be well approximated by the
second. Our results have several implications. First,
tactile displays using lateral skin deformation can
generate tactile sensations similar to those using
normal skin deformation. Second, a synthesis approach
can achieve this result if some constraints on the
design of tactile stimulators are met. Third, the
mechanoreceptors embedded in the skin must respond to
the deviatoric part of the strain tensor field and not
to its volumetric part. Finally, many tactile stimuli
might represent, for the brain, an inverse problem to
be solved, such specific examples of ``tactile
metameres'' are given.",

will find it easier to recognize overall structure.
Nine participants were asked to explore simple 3D

in various spatial configurations and asked to identify
the nodes and draw their overall structure. Various
combinations of haptic and auditory feedback were
explored. Our results demonstrate that haptic cues
significantly helped participants to quickly recognize
nodes and structure. Surprisingly, auditory cues alone
did not speed up node recognition; however, when they
were combined with haptics both node identification and
structure recognition significantly improved. This
result demonstrates that haptic feedback plays an

understanding of the relevant aspects of visual
perception, in the form of fully automated
computational heuristics that can efficiently identify
locations that would attract human gaze in complex

designing such heuristics draws on ideas from
computational neuroscience. We compared several
neurobiologically inspired heuristics with eye-movement
recordings from five observers playing video games, and
found that human gaze was better predicted by
heuristics that detect outliers from the global
distribution of visual features than by purely local
heuristics. Heuristics sensitive to dynamic events
performed best overall. Further, heuristic prediction
power differed more between games than between
different human observers. While other factors clearly
also influence eye position, our findings suggest that
simple neurally inspired algorithmic methods can
account for a significant portion of human gaze
behavior in a naturalistic, interactive setting. These
algorithms may be useful in the implementation of
interactive virtual environments, both to predict the

under a small subset of illumination directions. We
then tested observers' recognition ability under
different illuminations. Across all experiments,
recognition performance was found to be dependent on
the distance between the trained and tested
illumination directions. This effect was modulated by
the nature of the trained illumination directions.
Generalizations from frontal illuminations were
different than generalizations from extreme
illuminations. Similarly, the IC model was also
sensitive to whether the trained images were
near-frontal or extreme. Thus, we find that the nature
of the images in the training set affects the accuracy
of an object's representation under variable lighting
for both humans and the model. Beyond this general
correspondence, the microstructure of the
generalization patterns for both humans and the IC
model were remarkably similar, suggesting that the two

multiscale patches from each face image before
projecting them into a common feature space. The degree
of ``distinctiveness'' of any patch depends on its
distance in feature space from patches mapped from
other individuals. First a pairwise analysis is
developed and then a simple generalization to the
multiple-face case is proposed. A perceptual
experiment, involving 45 observers, indicates the
method to be fairly compatible with how humans mark
faces as distinct. A quantitative example of face
authentication is also performed in order to show the
essential role played by the distinctive information. A
comparative analysis shows that performance of our

we propose a tone-mapping operator (TMO) to compress

driving situation. We address three display issues of
some consequences for road image display: luminance
dynamics, image quantization, and high minimum
displayable luminance. Our TMO characterizes the
effects of local adaptation with a bandpass
decomposition of the image using a Laplacian pyramid,
and processes the levels separately in order to mimic
the human visual system. The contrast perception model
uses the visibility level, a usual index in road
visibility engineering applications. To assess our
algorithm, a psychophysical experiment devoted to a
target detection task was designed. Using a Landolt
ring, the visual performances of 30 observers were
measured: they stared first at a high-dynamic range
image and then at the same image processed by a TMO and
displayed on a low-dynamic range monitor, for
comparison. The evaluation was completed with a visual
appearance evaluation. Our operator gives good
performances for three typical road situations (one in
daylight and two at night), after comparison with four
standard TMOs from the literature. The psychovisual

we investigated the possibility of simulating
sensations of texture without haptic devices by using
the sole manipulation of the speed of a mouse cursor (a
technique called speed technique). In this paper, we
describe another technique (called Size technique) to
enhance the speed technique and simulate texture
sensations by varying the size of the cursor according
to the local height of the texture displayed on the
computer screen. With the size technique, the user
would see an increase (decrease) in cursor size
corresponding to a positive (negative) slope of the
texture. We have conducted a series of experiments to
study and compare the use of both the size and speed
technique for simulating simple shapes like bumps and
holes. In Experiment 1, our results showed that
participants could successfully identify bumps and
holes using the size technique alone. Performances
obtained with the size technique reached a similar
level of accuracy as found previously with the speed
technique alone. In Experiment 2, we determined a point
of subjective equality between bumps simulated by each
technique separately, which suggests that the two
techniques provide information that can be perceptually
equivalent. In Experiment 3, using paradoxical
situations of conflict between the two techniques, we
have found that participants' answers were more
influenced by the size technique, suggesting a
dominance of the size over the speed technique.
Furthermore, we have found a mutual reinforcement of
the techniques, i.e., when the two techniques were
consistently combined, the participants were more
efficient in identifying the simulated shapes. In
Experiment 4, we further observed the complex
interactions between the information associated with
the two techniques in the perception and in the
decision process related to the accurate identification
of bumps and holes. Taken together, our results promote
the use of both techniques for the low-cost simulation

a greedy approach to estimate the order in which

a very coarse approximation. We perform a user study to
validate its behaviour, as well as investigate the
impact of the choice of image fidelity metric as well

considered fall in the physical, statistical and
perceptual categories. The overall benefit of our
method is the semiautomation of the view selection

thriftier in texture memory use and faster to render.
Using the same framework, we adjust the parameters of

character, and a point light walker. Three different
types of motion were applied to all models: motion
captured male and female walks, and neutral synthetic
walks. We found that both form and motion influence sex
perception for these characters: for neutral synthetic
motions, form determines perceived sex, whereas natural
motion affects the perceived sex of both androgynous
and realistic forms. These results indicate that the
use of neutral walks is better than creating ambiguity
by assigning an incongruent motion. In Experiment 2 we
investigated further the influence of body shape and
motion on realistic male and female models and found
that adding stereotypical indicators of sex to the body
shapes influenced sex perception. Also, that
exaggerated female body shapes influences sex
judgements more than exaggerated male shapes. These
results have implications for variety and realism when
simulating large crowds of virtual characters.",

operations such as compression, simplification or
watermarking, which may introduce some geometric
artifacts on the shape. The main issue is to maximize
the compression/simplification ratio or the watermark
strength while minimizing these visual degradations.
However few algorithms exploit the human visual system
to {\em hide\/} these degradations, while perceptual
attributes could be quite relevant for this task.
Particularly, the {\em masking effect\/} defines the
fact that one visual pattern can hide the visibility of
another. In this context we introduce an algorithm for
estimating the {\em roughness\/} of a 3D mesh, as a
local measure of geometric noise on the surface.
Indeed, a textured (or {\em rough\/}) region is able to
hide geometric distortions much better than a smooth
one. Our measure is based on curvature analysis on
local windows of the mesh and is independent of the
resolution/connectivity of the object. The accuracy and
the robustness of our measure, together with its
relevance regarding visual masking have been
demonstrated through extensive comparisons with
state-of-the-art and subjective experiment. Two
applications are also presented, in which the roughness
is used to lead (and improve) respectively compression
and watermarking algorithms.",

that a static representation is highly ambiguous, even
in simple cases, but this can be counterbalanced by use
of dynamic cues (i.e., motion parallax) provided that

provide relevant information to disambiguate depth

whether visually induced circular vection can be
enhanced by concurrently rotating auditory cues that
match visual landmarks (e.g., a fountain sound).
Participants sat behind a curved projection screen
displaying rotating panoramic renderings of a market
place. Apart from a no-sound condition, headphone-based
auditory stimuli consisted of mono sound, ambient
sound, or low-/high-spatial resolution auralizations
using generic head-related transfer functions (HRTFs).
While merely adding nonrotating (mono or ambient) sound
showed no effects, moving sound stimuli facilitated
both vection and presence in the virtual environment.
This spatialization benefit was maximal for a medium
($20^\circ \times 15^\circ$) FOV, reduced for a larger
($54^\circ \times 45^\circ$) FOV and unexpectedly
absent for the smallest ($10^\circ \times 7.5^\circ$)
FOV. Increasing auralization spatial fidelity (from
low, comparable to five-channel home theatre systems,
to high, $5^\circ$ resolution) provided no further
benefit, suggesting a ceiling effect. In conclusion,
both self-motion perception and presence can benefit
from adding moving auditory stimuli. This has important
implications both for multimodal cue integration
theories and the applied challenge of building
affordable yet effective motion simulators.",

intended. This is a surprising result given how well
people act in real environments. The behavior in the

locomote without vision. Either could result from
issues related to added mass, moments of inertia, and
restricted field of view in HMDs. This article
describes an experiment in which distance judgments
based on normal real-world and HMD viewing are compared
with judgments based on real-world viewing while
wearing two specialized devices. One is a mock HMD,
which replicated the mass, moments of inertia, and
field of view of the HMD and the other an inertial
headband designed to replicate the mass and moments of
inertia of the HMD, but constructed to not restrict the
field of view of the observer or otherwise feel like
wearing a helmet. Distance judgments using the mock HMD
showed a statistically significant underestimation
relative to the no restriction condition but not of a

conditions. This holds significant implications for
chromatic Level Of Detail management. Specifically,
while peripheral spatiotemporal detail can be
attenuated without affecting visual search, often
dramatically (e.g., spatial detail can be so reduced up

reduction is likely to be noticed much sooner.

measure, such as visual complexity, as an implicit
marker of cognitive load, we can design Web pages which
are easier to interact with. We have devised an initial
empirical experiment, using card sorting and triadic
elicitation, to test our theories and assumptions, and
have built an initial baseline sequence of 20 Web pages
along with a library of qualitative and anecdotal
feedback. Using this library, we define visual
complexity, ergo perceived interaction complexity, and
by taking these pages as ``prototypes'' and ranking
them into a sequence of complexity, we are able to
group them into: simple, neutral, and complex. This

abstract = "Visual perception is an inherently selective process.
To understand when and why a particular region of a
scene is selected, it is imperative to observe and
describe the eye movements of individuals as they go
about performing specific tasks. In this sense, vision
is an active process that integrates scene properties
with specific, goal-oriented oculomotor behavior. This
study is an investigation of how task influences the
visual selection of stimuli from a scene. Four eye
tracking experiments were designed and conducted to
determine how everyday tasks affect oculomotor
behavior. A portable eyetracker was created for the
specific purpose of bringing the experiments out of the
laboratory and into the real world, where natural
behavior is most likely to occur. The experiments
provide evidence that the human visual system is not a
passive collector of salient environmental stimuli, nor
is vision general-purpose. Rather, vision is active and
specific, tightly coupled to the requirements of a task
and a plan of action. The experiments support the
hypothesis that the purpose of selective attention is
to maximize task efficiency by fixating relevant
objects in the scene. A computational model of visual
attention is presented that imposes a high-level
constraint on the bottom-up salient properties of a
scene for the purpose of locating regions that are
likely to correspond to foreground objects rather than
background or other salient nonobject stimuli. In
addition to improving the correlation to human subject
fixation densities over a strictly bottom-up model
[Itti et al. 1998; Parkhurst et al. 2002], this model
predicts a central fixation tendency when that tendency
is warranted, and not as an artificially primed
location bias.",

tolerance for certain types of errors is significantly
higher in a realistic snooker scenario than in the
abstract test settings previously used to examine those
errors. By contrast, we find tolerance for errors
displayed in realistic but more neutral environments
was not different from tolerance for those errors in
abstract settings. Additionally, we examine the
interaction of auditory and visual cues in determining
participant sensitivity to spatiotemporal errors in
rigid body collisions. We find that participants are
predominantly affected by visual cues. Finally, we find
that tolerance for spatial gaps during collision events
is constant for a wide range of viewing angles if the
effect of foreshortening and occlusion caused by the
viewing angle is taken into account.",

abstract = "Video-based eye trackers produce an output video
showing where a subject is looking, the subject's
Point-of-Regard (POR), for each frame of a video of the
scene. This information can be extremely valuable, but
its analysis can be overwhelming. Analysis of
eye-tracked data from portable (wearable) eye trackers
is especially daunting, as the scene video may be
constantly changing, rendering automatic analysis more
difficult. A common way to begin analysis of POR data
is to group these data into fixations. In a previous
article, we compared the fixations identified (i.e.,
start and end marked) automatically by an algorithm to
those identified manually by users (i.e., manual
coders). Here, we extend this automatic identification
of fixations to tagging each fixation to a
Region-of-Interest (ROI). Our fixation tagging
algorithm, FixTag, requires the relative 3D positions
of the vertices of ROIs and calibration of the scene
camera. Fixation tagging is performed by first
calculating the camera projection matrices for
keyframes of the scene video (captured by the eye
tracker) via an iterative structure and motion recovery
algorithm. These matrices are then used to project 3D
ROI vertices into the keyframes. A POR for each
fixation is matched to a point in the closest keyframe,
which is then checked against the 2D projected ROI
vertices for tagging. Our fixation tags were compared
to those produced by three manual coders tagging the
automatically identified fixations for two different
scenarios. For each scenario, eight ROIs were defined
along with the 3D positions of eight calibration
points. Therefore, 17 tags were available for each
fixation: 8 for ROIs, 8 for calibration points, and 1
for ``other.'' For the first scenario, a subject was
tracked looking through products on four store shelves,
resulting in 182 automatically identified fixations.
Our automatic tagging algorithm produced tags that
matched those produced by at least one manual coder for
181 out of the 182 fixations (99.5\% agreement). For
the second scenario, a subject was tracked looking at
two posters on adjoining walls of a room. Our algorithm
matched at least one manual coder's tag for 169
fixations out of 172 automatically identified (98.3\%
agreement).",

of extra modulations, which do not correspond to a

this article, we employ perceptually-based methods to
allow more efficient handling of these data. In the
first step, we analyse different uniform resampling by
means of a psychophysical study with 11 subjects,
comparing original data with rendering of a uniformly
resampled version over the hemisphere of illumination
and view-dependent textural measurements. We have found
that down-sampling in view and illumination azimuthal
angles is less apparent than in elevation angles and
that illumination directions can be down-sampled more
than view directions without loss of visual accuracy.
In the second step, we analyzed subjects gaze fixation
during the experiment. The gaze analysis confirmed
results from the experiment and revealed that subjects
were fixating at locations aligned with direction of
main gradient in rendered stimuli. As this gradient was
mostly aligned with illumination gradient, we conclude
that subjects were observing materials mainly in
direction of illumination gradient. Our results provide
interesting insights in human perception of real

Experiment 1 investigated whether auditory circular

that actual motion is possible or not. While previous
studies often seated participants on movable chairs to
suspend the disbelief of self-motion, it has never been
investigated whether this does, in fact, facilitate
auditory vection. To this end, 23 blindfolded
participants were seated on a hammock chair with their
feet either on solid ground (``movement impossible'')
or suspended (``movement possible'') while listening to
individualized binaural recordings of two sound sources
rotating synchronously at $60^\circ / s$. Although
participants never physically moved, situational
awareness of movability facilitated auditory vection.
Moreover, adding slight vibrations like the ones
resulting from actual chair rotation increased the
frequency and intensity of vection. Experiment 2
extended these findings and showed that
nonindividualized binaural recordings were as effective
in inducing auditory circular vection as individualized
recordings. These results have important implications

We discuss existing transition approaches, with
emphasis on the additional information they require and
on the constraints they place on the authoring process.
We propose a compromise approach based on faking the
parallax effect with occluder mattes. We conduct a user
study to determine whether additional information does
in fact increase the visual appeal of transitions. We
observe that the creation of occluder mattes alone is
only justified if the fake parallax effect can be
synchronized with the camera motion (but not
necessarily consistent with it), and if viewpoint
discrepancies at occlusion boundaries are small. The
faster the transition, the less perceptual value there
is in creating mattes. Information on view alignment is
always useful, as a dissolve effect is always preferred

key role in digital image applications such as the
development of image quality metrics. However, little
attention has been paid to their applicability to
peripheral vision. Central (i.e., foveal) vision is
extremely sensitive for the contrast detection of
simple stimuli such as sinusoidal gratings, but
peripheral vision is less sensitive. Furthermore,
crowding is a well-documented phenomenon whereby
differences in suprathreshold peripherally viewed
target objects (such as individual letters or patches
of sinusoidal grating) become more difficult to
discriminate when surrounded by other objects
(flankers). We examine three factors that might
influence the degree of crowding with natural-scene
stimuli (cropped from photographs of natural scenes):
(1) location in the visual field, (2) distance between
target and flankers, and (3) flanker-target similarity.
We ask how these factors affect crowding in a
suprathreshold discrimination experiment where
observers rate the perceived differences between two
sequentially presented target patches of natural
images. The targets might differ in the shape, size,
arrangement, or color of items in the scenes. Changes
in uncrowded peripheral targets are perceived to be
less than for the same changes viewed foveally.
Consistent with previous research on simple stimuli, we
find that crowding in the periphery (but not in the
fovea) reduces the magnitudes of perceived changes even
further, especially when the flankers are closer and
more similar to the target. We have tested VDP models
based on the response behavior of neurons in visual
cortex and the inhibitory interactions between them.
The models do not explain the lower ratings for
peripherally viewed changes even when the lower
peripheral contrast sensitivity was accounted for; nor
could they explain the effects of crowding, which
others have suggested might arise from errors in the
spatial localization of features in the peripheral
image. This suggests that conventional VDP models do
not port well to peripheral vision.",

wearer must visually monitor the limb, which is often
inconvenient or even impossible for some tasks. This
work seeks to quantify the potential benefits of
incorporating proprioceptive motion feedback into
upper-limb prosthesis designs. We apply a noninvasive
method for controlling the availability of
proprioceptive motion feedback in unimpaired
individuals in a human subject study to compare the
benefits of visual and proprioceptive motion feedback
in targeted motion tasks. Combined results of the
current study and our previous study using a different
task indicate that the addition of proprioceptive
motion feedback improves targeting accuracy under
nonsighted conditions and, for some tasks, under
sighted conditions as well. This work motivates the
development of methods for providing artificial
proprioceptive feedback to a prosthesis wearer.",

crucial image quality attributes and dimensions and the
description of each pipeline's perceived image quality
performance. We found that the subjectively most
important image quality dimensions were color
shift/naturalness, darkness, and sharpness. The first
dimension, which was related to naturalness and colors,
distinguished the good-quality pipelines from the
middle- and low-quality groups, and the dimensions of
darkness and sharpness described why the quality failed
in the low-quality pipelines. The study suggests that
the high-level concept naturalness is a requirement for
high-quality images, whereas quality can fail for other
reasons in low-quality images, and this failure can be
described by low-level concepts, such as darkness and
sharpness.",

pen-gesture interfaces in a series of informal and
formal experiments. Initial iterative exploration
showed that gaining performance advantage with auditory
feedback was possible using absolute cues and state
feedback after the gesture was produced and recognized.
However, gaining learning or performance advantage from
auditory feedback tightly coupled with the pen-gesture
articulation and recognition process was more
difficult. To establish a systematic baseline,
Experiment 1 formally evaluated gesture production
accuracy as a function of auditory and visual feedback.
Size of gestures and the aperture of the closed
gestures were influenced by the visual or auditory
feedback, while other measures such as shape distance
and directional difference were not, supporting the
theory that feedback is too slow to strongly influence
the production of pen stroke gestures. Experiment 2
focused on the subjective aspects of auditory feedback
in pen-gesture interfaces. Participants' rating on the
dimensions of being wonderful and stimulating was
significantly higher with musical auditory feedback.
Several lessons regarding pen gestures and auditory
feedback are drawn from our exploration: a few simple
functions such as indicating the pen-gesture
recognition results can be achieved, gaining
performance and learning advantage through tightly
coupled process-based auditory feedback is difficult,
pen-gesture sets and their recognizers can be designed
to minimize visual dependence, and people's subjective
experience of gesture interaction can be influenced
using musical auditory feedback. These lessons may
serve as references and stepping stones toward future
research and development in pen-gesture interfaces with
auditory feedback.",

certified pilots were instructed to quickly achieve and
then maintain a constant 3-degree glideslope relative

found to make significant glideslope control errors,
especially during simulated night approaches. We found
that pilot gaze was directed most often toward the
runway and to the ground region located immediately in
front of the runway, compared to other visual scene
features. In general, their gaze was skewed toward the
near half of the runway and tended to follow the runway
threshold as it moved on the screen. Contrary to
expectations, pilot gaze was not consistently directed
at the aircraft's simulated aimpoint (i.e., its
predicted future touchdown point based on scene
motion). However, pilots did tend to fly the aircraft
so that this point was aligned with the runway
threshold. We conclude that the supplementary
out-of-cockpit visual cues available during day landing
conditions facilitated glideslope control performance.
The available evidence suggests that these
supplementary visual cues are acquired through
peripheral vision, without the need for active
fixation.",

judgments of advection pathways than others. In this
article, we develop this theory through a numerical
model of the primary visual cortex of the brain (Visual
Area 1) where contour enhancement is understood to
occur according to most neurological theories. We apply
a two-stage model of contour perception to various
visual representations of flow fields evaluated using
the advection task of Laidlaw et al. In the first
stage, contour {\em enhancement\/} is modeled based on
Li's cortical model. In the second stage, a model of
streamline {\em tracing\/} is proposed, designed to
support the advection task. We examine the predictive
power of the model by comparing its performance to that
of human subjects on the advection task with four
different visualizations. The results show the same
overall pattern for humans and the model. In both
cases, the best performance was obtained with an
aligned streamline based method, which tied with a
LIC-based method. Using a regular or jittered grid of
arrows produced worse results. The model yields
insights into the relative strengths of different flow
visualization methods for the task of visualizing
advection pathways.",

in performance capture and advanced rendering
techniques have allowed the movie industry in
particular to create characters that appear very
human-like. However, with these new capabilities has
come the realization that such characters are yet not
quite ``right.'' One possible hypothesis is that these
virtual humans fall into an ``Uncanny Valley'', where
the viewer's emotional response is repulsion or
rejection, rather than the empathy or emotional
engagement that their creators had hoped for. To
explore these issues, we created three animated
vignettes of an arguing couple with detailed motion for
the face, eyes, hair, and body. In a set of perceptual
experiments, we explore the relative importance of
different anomalies using two different methods: a
questionnaire to determine the emotional response to
the full-length vignettes, with and without facial
motion and audio; and a 2AFC (two alternative forced
choice) task to compare the performance of a virtual
``actor'' in short clips (extracts from the vignettes)
depicting a range of different facial and body
anomalies. We found that the facial anomalies are
particularly salient, even when very significant body
animation anomalies are present.",

voice synchronization, an aspect of video quality that
is strongly affected by current post-production and
transmission practices. We examined the synchronization
of an actor's voice and lip movements in two distinct
scenarios. First, we simulated the temporal mismatch
between the audio and video tracks that can occur
during dubbing or during broadcast. Next, we recreated
the pitch changes that result from conversions between
formats with different frame rates. We show, for the
first time, that these audio visual mismatches affect
viewer enjoyment. When temporal synchronization is
noticeably absent, there is a decrease in the perceived
performance quality and the perceived emotional
intensity of a performance. For pitch changes, we find
that higher pitch voices are not preferred, especially
for male actors. Based on our findings, we advise that
mismatched audio and video signals negatively affect
viewer experience.",

observers for stereo images than for mono images in two
out of three scenes. A similar result was found for the
depth range: for the same two scenes the stereo images
were perceived as having more depth than the monocular
images. In addition, our method allowed us to determine
the subjective center of projection. We found that the
pointing settings fitted the reconstructed depth best

scenes with sufficient monocular information may not

implemented in a fast multiscale second-generation

able to create high-quality, perceptually convincing
transitions between recorded images. By implementing
concepts derived from human vision, the problem of a
physically correct image interpolation is relaxed to
that of image interpolation which is perceived as
visually correct by human observers. We find that it
suffices to focus on exact edge correspondences,
homogeneous regions and coherent motion to compute
convincing results. A user study confirms the visual
quality of the proposed image interpolation approach.
We show how each aspect of our approach increases

and a support vector machine (SVM) that relies on 90
eye movement features extracted from the eye movement
data. We evaluate both methods in a study performed
with eight participants reading while sitting at a
desk, standing, walking indoors and outdoors, and
riding a tram. We introduce a method to segment reading
activity by exploiting the sensorimotor coordination of
eye and head movements during reading. Using
person-independent training, we obtain an average
precision for recognizing reading of 88.9\% (recall
72.3\%) using STR and of 87.7\% (recall 87.9\%) using
SVM over all participants. We show that the proposed
segmentation scheme improves the performance of
recognizing reading events by more than 24\%. Our work
demonstrates that the joint analysis of eye and body
movements is beneficial for reading recognition and
opens up discussion on the wider applicability of a
multimodal recognition approach to other visual and
physical activities.",

a virtual character to move participants to a specified
location. The virtual environment depicted an alleyway
displayed through a wide field-of-view head-tracked
stereo head-mounted display. Based on proxemics theory,
we predicted that when the character approached within
a personal or intimate distance to the participants,
they would be inclined to move backwards out of the
way. We carried out a between-groups experiment with 30
female participants, with 10 assigned arbitrarily to
each of the following three groups: In the Intimate
condition the character could approach within 0.38m and
in the Social condition no nearer than 1.2m. In the
Random condition the actions of the virtual character
were chosen randomly from among the same set as in the
RL method, and the virtual character could approach
within 0.38m. The experiment continued in each case
until the participant either reached the target or 7
minutes had elapsed. The distributions of the times
taken to reach the target showed significant
differences between the three groups, with 9 out of 10
in the Intimate condition reaching the target
significantly faster than the 6 out of 10 who reached
the target in the Social condition. Only 1 out of 10 in
the Random condition reached the target. The experiment
is an example of applied presence theory: we rely on
the many findings that people tend to respond
realistically in immersive virtual environments, and
use this to get people to achieve a task of which they
had been unaware. This method opens up the door for
many such applications where the virtual environment
adapts to the responses of the human participants with

to explore the perception of artifacts that typically
appear during rendering and determine the perceptual
quality of a sequence of images. Although there is an
emerging interest in using an EEG for image quality
assessment, one of the main impediments to the use of
an EEG is the very low Signal-to-Noise Ratio (SNR)
which makes it exceedingly difficult to distinguish
neural responses from noise. Traditionally,
event-related potentials have been used for analysis of
EEG data. However, they rely on averaging and so
require a large number of participants and trials to
get meaningful data. Also, due to the low SNR ERP's
are not suited for single-trial classification. We
propose a novel wavelet-based approach for evaluating
EEG signals which allows us to predict the perceived
image quality from only a single trial. Our
wavelet-based algorithm is able to filter the EEG data
and remove noise, eliminating the need for many
participants or many trials. With this approach it is
possible to use data from only 10 electrode channels
for single-trial classification and predict the
presence of an artifact with an accuracy of 85\%. We
also show that it is possible to differentiate and
classify a trial based on the exact type of artifact
viewed. Our work is particularly useful for

challenges in synthesizing stereo motion panoramas, for
example, to ensure temporal synchronization between
left and right views in each frame, to avoid spatial
distortion of moving objects, and to continuously loop
the video in time. We have recently developed a stereo
motion panorama method that tries to address some of
these challenges. The method blends space-time regions
of a video XYT volume, such that the blending regions
are distinct and translate over time. This article
presents a perception experiment that evaluates certain
aspects of the method, namely how well observers can
detect such blending regions. We measure detection time
thresholds for different blending widths and for
different scenes, and for monoscopic versus
stereoscopic videos. Our results suggest that blending
may be more effective in image regions that do not
contain coherent moving objects that can be tracked
over time. For example, we found moving water and
partly transparent smoke were more effectively blended

photometric and appearance-based variability was
estimated using a face recognition algorithm created by
fusing three top-performing algorithms from a recent
international competition. The algorithm computed
similarity scores for a constant set of same-identity
and different-identity pairings from multiple images.
Image pairs were assigned to good, moderate, and poor
accuracy groups by ranking the similarity scores for
each identity pairing, and dividing these rankings into
three strata. This procedure isolated the role of
photometric variables from the effects of the
distinctiveness of particular identities. Algorithm
performance for these constant identity pairings varied
dramatically across the groups. In a series of
experiments, humans matched image pairs from the good,
moderate, and poor conditions, rating the likelihood
that the images were of the same person (1: sure same
--- 5: sure different). Algorithms were more accurate
than humans in the good and moderate conditions, but
were comparable to humans in the poor accuracy
condition. To date, these are the most variable
illumination- and appearance-based recognition
conditions on which humans and machines have been
compared. The finding that machines were never less
accurate than humans on these challenging frontal
images suggests that face recognition systems may be
ready for applications with comparable difficulty. We
speculate that the superiority of algorithms over
humans in the less challenging conditions may be due to
the algorithms' use of detailed, view-specific identity
information. Humans may consider this information less
important due to its limited potential for robust
generalization in suboptimal viewing conditions.",

to communicate geometrical data related to a virtual

multimodal interface for product design. The interface
allows a designer to evaluate the quality of a 3-D
shape using touch, vision, and sound. Two important
considerations addressed in this article are the nature
of the data that is sonified and the haptic interaction
between the user and the interface, which in fact
triggers the sound and influences its characteristics.
Based on these considerations, we present a number of
sonification strategies that are designed to map the
geometrical data of interest into sound. The
fundamental frequency of various sounds was used to
convey the curve shape or the curvature to the
listeners. Two evaluation experiments are described,
one involves participants with a varied background, the
other involved the intended users, i.e. participants
with a background in industrial design. The results
show that independent of the sonification method used
and independent of whether the curve shape or the
curvature were sonified, the sonification was quite
successful. In the first experiment participants had a
success rate of about 80\% in a multiple choice task,
in the second experiment it took the participants on
average less than 20 seconds to find the maximum,

for interpreting the underlying contents, and this
process is usually accompanied by subtle aesthetic
pleasure. We study this phenomenon through human

abstract art and photographs, and quantitatively
verify, the increased perceptual ambiguities in terms
of recognition accuracy and response time. Based on the
studies, we measure the level of perceptual ambiguity

information theory, and propose a painterly rendering
method with interactive control of the ambiguity
levels. Given an input photograph, we first segment it
into regions corresponding to different objects and
parts in an interactive manner and organize them into a
hierarchical parse tree representation. Then we execute
a painterly rendering process with image obscuring
operators to transfer the photograph into an abstract
painting style with increased perceptual ambiguities in
both the scene and individual objects. Finally, using
kernel density estimation and message-passing
algorithms, we compute and control the ambiguity levels
numerically to the desired levels, during which we may
predict and control the viewer's perceptual path among

process in human perception of faces, but little study
has been reported on how to objectively measure the

proposed to quantitatively measure the familiarity of a

been seen previously. The proposed method models the
context-free and context-dependent forms of familiarity
suggested by psychological studies and accounts for the
key factors, namely exposure frequency, exposure
intensity and similar exposure, that affect human
perception of face familiarity. Specifically, the
method divides the reference set into nonexclusive
groups and measures the familiarity of a given face by
aggregating the similarities of the face to the
individual groups. In addition, the nonnegative matrix
factorization (NMF) is extended in this paper to learn
a compact and localized subspace representation for
measuring the similarities of the face with respect to
the individual groups. The proposed method has been
evaluated through experiments that follow the protocols
commonly used in psychological studies and has been
compared with subjective evaluation. Results have shown
that the proposed measurement is highly consistent with
the subjective judgment of face familiarity. Moreover,
a face recognition method is devised using the concept
of face familiarity and the results on the standard

Three metrics were used: travel time, collisions (a
measure of accuracy), and the speed profile. The time
that participants required to reach asymptotic
performance for traveling, and what that asymptote was,
varied considerably between interfaces. In particular,
when a world had tight turns (0.75 m corridors),
participants who walked were more proficient than those
who used a joystick to locomote and turned either
physically or with a joystick, even after 10 minutes of
training. The speed profile showed that this was caused
by participants spending a notable percentage of the
time stationary, irrespective of whether or not they
frequently played computer games. The study shows how
speed profiles can be used to help evaluate
participants' proficiency with travel interfaces,
highlights the need for training to be structured to
addresses specific weaknesses in proficiency (e.g.,
start-stop movement), and for studies to measure and

the precision of estimates. To explain the results, we
present an edge-aware orientation map based on image

displacement caused rectangles on the ground plane to
be judged as larger and smaller in depth, respectively,

were in the same direction as cue-based model
predictions but of smaller magnitude. Displacement from

modality, or because of an adjustment of locomotion to
the physical properties evoked by the sounds simulating
the ground materials. The results reported in this
study suggest that auditory feedback may be more
important in the regulation of walking in natural
environments than has been acknowledged. Furthermore,
auditory feedback could be used to develop novel
approaches to the design of therapeutic and

three different speed regulation instructions:
``accelerate your speed,'' ``keep your speed
constant,'' and ``decelerate your speed,''

so that one of the groups was first taught (i.e.,
primed) the meanings of the stimuli, whereas the other

modality and richness of feedback were only important
in that traditional color change feedback did not
perform as well as audio or haptic feedback. In
combination, the experiments indicated that in
immersive virtual environments the stop collision

some anatomical accuracy for computational speed and

Practical applications of the model might include
improved noise reduction and signal recovery facilities

to determine user effort during usability testing, and
enhanced security in biometric identification systems.
The results indicate that the model is capable of
produce oblique saccades with properties resembling
those of normal human saccades and is capable of
deriving muscle constants that are viable as biometric
indicators. Therefore, we conclude that sacrifice in
the anatomical accuracy of the model produces
negligible effects on the accuracy of saccadic

through a listening test. In the second experiment,
participants performed arm and hand gestures

watching their own video recordings. They were
questioned on their perception of the listened sounds

the sounds where causal action can be identified,
participants mainly mimic the action that has produced
the sound. In the other case, when no action can be
associated with the sound, participants trace contours
related to sound acoustic features. We also found that

to report the full 3D gaze position. Our system employs
a 3D calibration process that determines the parameters
of a mapping from a naive depth estimate, based simply
on triangulation, to a refined 3D gaze point estimate
tuned to a particular user. We show that our system is
an improvement on the geometry-based 3D gaze estimation
returned by a proprietary algorithm provided with our
tracker. We also compare our approach with that of the
Parameterized Self-Organizing Map (PSOM) method, due to
Essig and colleagues, which also individually
calibrates to each user. We argue that our method is
superior in speed and ease of calibration, is easier to
implement, and does not require an iterative solver to
produce a gaze position, thus guaranteeing computation
at the rate of tracker acquisition. In addition, we
report on a user study that indicates that, compared
with PSOM, our method more accurately estimates gaze
depth, and is nearly as accurate in estimating
horizontal and vertical position. Results are verified
on two different 4D eye tracking systems, a high
accuracy Wheatstone haploscope and a medium accuracy
active stereo display. Thus, it is the recommended

feedback in teleoperation is presented. Cutaneous cues
provide less transparency than kinesthetic force, but
they do not affect the stability of the teleoperation
system. On the other hand, kinesthesia provides a
compelling illusion of telepresence but affects the
stability of the haptic loop. However, when employing
common grounded haptic interfaces, it is not possible
to independently control the cutaneous and kinesthetic
components of the interaction. For this reason, many
control techniques ensure a stable interaction by
scaling down both kinesthetic and cutaneous force
feedback, even though acting on the cutaneous channel
is not necessary. We discuss here the feasibility of a
novel approach. It aims at improving the realism of the
haptic rendering, while preserving its stability, by
modulating cutaneous force to compensate for a lack of
kinesthesia. We carried out two teleoperation
experiments, evaluating (1) the role of cutaneous
stimuli when reducing kinesthesia and (2) the extent to
which an overactuation of the cutaneous channel can
fully compensate for a lack of kinesthetic force
feedback. Results showed that, to some extent, it is
possible to compensate for a lack of kinesthesia with
the aforementioned technique, without significant

visual realism of face images is important. Efficient
control is enabled by a deep understanding of visual
realism perception: the extent to which viewers judge
an image as a real photograph rather than a CG image.
Across two experiments, we explored the processes
involved in visual realism perception of face images.
In Experiment 1, participants made visual realism
judgments on original face images, inverted face
images, and images of faces that had the top and bottom
halves misaligned. In Experiment 2, participants made
visual realism judgments on original face images,
scrambled faces, and images that showed different parts
of faces. Our findings indicate that both holistic and
piecemeal processing are involved in visual realism
perception of faces, with holistic processing becoming
more dominant when resolution is lower. Our results
also suggest that shading information is more important
than color for holistic processing, and that inversion
makes visual realism judgments harder for realistic
images but not for unrealistic images. Furthermore, we
found that eyes are the most influential face part for
visual realism, and face context is critical for
evaluating realism of face parts. To the best of our

corollary of the hypothesis is attractive facial
geometric features construct a convex set. This
corollary derives a convex hull based face
beautification method, which guarantees attractiveness

Experimental results show its superiority to

Although phones are becoming more and more powerful,
operating system software is getting more and more

interested in gaining insight into touch-feedback
simultaneity and the effects of latency on the
perceived quality of touchscreen buttons. In an
experiment, we varied the latency between touch and
feedback between 0 and 300 ms for tactile, audio, and
visual feedback modalities. We modelled the proportion
of simultaneity perception as a function of latency for
each modality condition. We used a Gaussian model
fitted with the maximum likelihood estimation method to
the observations. These models showed that the point of
subjective simultaneity (PSS) was 5ms for tactile, 19ms
for audio, and 32ms for visual feedback. Our study
included the scoring of perceived quality for all of
the different latency conditions. The perceived quality
dropped significantly between latency conditions 70 and
100 ms when the feedback modality was tactile or audio,
and between 100 and 150 ms when the feedback modality
was visual. When the latency was 300ms for all feedback
modalities, the quality of the buttons was rated
significantly lower than in all of the other latency
conditions, suggesting that a long latency between a
touch on the screen and feedback is problematic for
users. Together with PSS and these quality ratings, a
75\% threshold was established to define a guideline
for the recommended latency range between touch and
feedback. Our guideline suggests that tactile feedback
latency should be between 5 and 50 ms, audio feedback
latency between 20 and 70 ms, and visual feedback
latency between 30 and 85 ms. Using these values will
ensure that users will perceive the feedback as
simultaneous with the finger's touch. These values also
ensure that the users do not perceive reduced quality.
These results will guide engineers and designers of
touchscreen interactions by showing the trade-offs
between latency and user preference and the effects
that their choices might have on the quality of the
interactions and feedback they design.",

abstract = "Animation budget constraints during the development of
a game often call for the use of a limited set of
generic motions. Editing operations are thus generally
required to animate virtual characters with a
sufficient level of variety. Evaluating the perceptual
plausibility of edited animations can therefore
contribute greatly towards producing visually plausible
animations. In this article, we study observers'
sensitivity to manipulations of overarm and underarm
biological throwing animations. In the first
experiment, we modified the release velocity of the
ball while leaving the motion of the virtual thrower
and the angle of release of the ball unchanged. In the
second experiment, we evaluated the possibility of
further modifying throwing animations by simultaneously
editing the motion of the thrower and the release
velocity of the ball, using dynamic time warping. In
both experiments, we found that participants perceived
shortened underarm throws to be particularly unnatural.
We also found that modifying the thrower's motion in
addition to modifying the release velocity of the ball
does not significantly improve the perceptual
plausibility of edited throwing animations. In the
third experiment, we modified the angle of release of
the ball while leaving the magnitude of release
velocity and the motion of the thrower unchanged, and
found that this editing operation is efficient for
improving the perceptual plausibility of shortened
underarm throws. Finally, in Experiment 4, we replaced
the virtual human thrower with a mechanical throwing
device (a ramp) and found the opposite pattern of
sensitivity to modifications of the release velocity,
indicating that biological and physical throws are
subject to different perceptual rules. Our results
provide valuable guidelines for developers of games and
virtual reality applications by specifying thresholds
for the perceptual plausibility of throwing
manipulations while also providing several interesting
insights for researchers in visual perception of
biological motion.",

perceptual experiments, we evaluate the genuineness of

of head motion in the perception of smiles and show
similar results for the impact of linearization on
animations with and without head motion. Our results
indicate that spontaneous smiles are more heavily
affected by linearizing the spatial and temporal
properties than posed smiles. Moreover, the spontaneous

strategies for haptic signals. Our approach relies on
experiments wherein we record the response of several
users to haptic stimuli. We then learn different
classifiers to predict the user response based on a
variety of causal signal features. The classifiers that
have good prediction accuracy serve as candidates to be
used in adaptive sampling. We compare the resultant
adaptive samplers based on their rate-distortion
tradeoff using synthetic as well as natural data. For
our experiments, we use a haptic device with a maximum
force level of 3 N and 10 users. Each user is subjected
to several piecewise constant haptic signals and is
required to click a button whenever he perceives a
change in the signal. For classification, we not only
use classifiers based on level crossings and Weber's
law but also random forests using a variety of causal
signal features. The random forest typically yields the
best prediction accuracy and a study of the importance
of variables suggests that the level crossings and
Weber's classifier features are most dominant. The
classifiers based on level crossings and Weber's law
have good accuracy (more than 90\%) and are only
marginally inferior to random forests. The level
crossings classifier consistently outperforms the one
based on Weber's law even though the gap is small.
Given their simple parametric form, the level crossings
and Weber's law--based classifiers are good candidates
to be used for adaptive sampling. We study their
rate-distortion performance and find that the level
crossing sampler is superior. For example, for haptic
signals obtained while exploring various rendered
objects, for an average sampling rate of 10 samples per
second, the level crossings adaptive sampler has a mean
square error about 3dB less than the Weber sampler.",

significantly improve many aspects of computer
graphics: scene design, interactivity and rendering.
Most previous attention models are mainly based on
low-level image features, and fail to take into account
high-level factors such as scene context, topology, or
task. Low-level saliency has previously been combined
with task maps, but only for predetermined tasks. Thus,
the application of these methods to graphics (e.g., for
selective rendering) has not achieved its full
potential. In this article, we present the first
automated high-level saliency predictor incorporating
two hypotheses from perception and cognitive science
that can be adapted to different tasks. The first
states that a scene is comprised of objects expected to
be found in a specific context as well objects out of
context which are salient (scene schemata) while the
other claims that viewer's attention is captured by
isolated objects (singletons). We propose a new model
of attention by extending Eckstein's Differential
Weighting Model. We conducted a formal eye-tracking
experiment which confirmed that object saliency guides
attention to specific objects in a game scene and
determined appropriate parameters for a model. We
present a GPU-based system architecture that estimates
the probabilities of objects to be attended in real-
time. We embedded this tool in a game level editor to
automatically adjust game level difficulty based on
object saliency, offering a novel way to facilitate

multipurpose tool for diverse applications in various
domains, for example, training, prototyping, design,
entertainment, and research investigating human
perception. However, for many of these applications, it
is necessary that the designed and computer-generated
virtual environments are perceived as a replica of the
real world. Many research studies have shown that this
is not necessarily the case. Specifically, egocentric
distances are underestimated compared to real-world
estimates regardless of whether the virtual environment
is displayed in a head-mounted display or on an
immersive large-screen display. While the main reason
for this observed distance underestimation is still
unknown, we investigate a potential approach to reduce
or even eliminate this distance underestimation.
Building up on the angle of declination below the
horizon relationship for perceiving egocentric
distances, we describe how eye height manipulations in
virtual reality should affect perceived distances. In
addition, we describe how this relationship could be
exploited to reduce distance underestimation for
individual users. In a first experiment, we investigate
the influence of a manipulated eye height on an
action-based measure of egocentric distance perception.
We found that eye height manipulations have similar
predictable effects on an action-based measure of
egocentric distance as we previously observed for a
cognitive measure. This might make this approach more
useful than other proposed solutions across different
scenarios in various domains, for example, for
collaborative tasks. In three additional experiments,
we investigate the influence of an individualized
manipulation of eye height to reduce distance
underestimation in a sparse-cue and a rich-cue
environment. In these experiments, we demonstrate that
a simple eye height manipulation can be used to
selectively alter perceived distances on an individual
basis, which could be helpful to enable every user to

abstract = "This article focuses on the identification and
perception of facial action units displayed alone as
well as the meaning decoding and perception of
full-face synthesized expressions of laughter. We argue
that the adequate representation of single action units
is important in the decoding and perception of
full-face expressions. In particular, we focus on three
factors that may influence the identification and
perception of single actions and full-face expressions:
their presentation mode (static vs. dynamic), their
intensity, and the presence of wrinkles. For the
purpose of this study, we used a hybrid approach for
animation synthesis that combines data-driven and
procedural animations with synthesized wrinkles
generated using a bump mapping method. Using such
animation technique, we created animations of single
action units and full-face movements of two virtual
characters. Next, we conducted two studies to evaluate
the role of presentation mode, intensity, and wrinkles
in single actions and full-face context-free
expressions. Our evaluation results show that intensity
and presentation mode influence (1) the identification
of single action units and (2) the perceived quality of
the animation. At the same time, wrinkles (3) are
useful in the identification of a single action unit
and (4) influence the perceived meaning attached to the
animation of full-face expressions. Thus, all factors
are important for successful communication of
expressions displayed by virtual characters.",

display odd and even rows of an image to either the
left or the right eye of the viewer. The visual system
then fuses the interlaced image into a single percept.
This row-based interlacing creates a small vertical
disparity between the images; however, interlacing may
also induce horizontal disparities, thus generating
depth artifacts. Whether people perceive the depth
artifacts and, if so, what is the magnitude of the
artifacts are unknown. In this study, we hypothesized
and tested if people perceive interlaced edges on
different depth levels. We tested oblique edge
orientations ranging from 2 degrees to 32 degrees and
pixel sizes ranging from 16 to 79 arcsec of visual
angle in a depth probe experiment. Five participants
viewed the visual stimuli through a stereoscope under
three viewing conditions: noninterlaced, interlaced,
and row averaged (i.e., where even and odd rows are
averaged). Our results indicated that people perceive
depth artifacts when viewing interlaced stereoscopic
images and that these depth artifacts increase with
pixel size and decrease with edge orientation angle. A
pixel size of 32 arcsec of visual angle still evoked
depth percepts, whereas 16 arcsec did not.
Row-averaging images effectively eliminated these depth
artifacts. These findings have implications for display
design, content production, image quality studies, and
stereoscopic games and software.",

compares people's judgments of affordances on two tasks

environment technologies enable precise control of the
myriad perceptual cues at work in the physical world

to decide how to act. In the experiments presented
here, the presence or absence of a self-avatar-an
animated graphical representation of a person embedded
in the virtual environment-was a central factor.
Another important factor was the presence or absence of
action, that is, whether people performed the task or

The results show that animated self-avatars provide

frequently reported to be shorter than intended. One
important parameter for spatial perception in a
stereoscopic virtual environment is the stereo
base-that is, the distance between the two viewing
cameras. We systematically varied the stereo base
relative to the interpupillary distance (IPD) and
examined influences on distance and size perception.
Furthermore, we tested whether an individual adjustment
of the stereo base through an alignment task would
reduce the errors in distance estimation. Participants
performed reaching movements toward a virtual tennis
ball either with closed eyes (blind reaches) or open
eyes (sighted reaches). Using the participants'
individual IPD, the stereo base was set to (a) the IPD,
(b) proportionally smaller, (c) proportionally larger,
or (d) adjusted according to the individual performance
in an alignment task that was conducted beforehand.
Overall, consistent with previous research, distances
were underestimated. As expected, with a smaller stereo
base, the virtual object was perceived as being farther
away and bigger, in contrast to a larger stereo base,
where the virtual object was perceived to be nearer and
smaller. However, the manipulation of the stereo base
influenced blind reaching estimates to a smaller extent
than expected, which might be due to a combination of
binocular disparity and pictorial depth cues. In
sighted reaching, when visual feedback was available,
presumably the use of disparity matching led to a
larger effect of the stereo base. The use of an
individually adjusted stereo base diminished the
average underestimation but did not reduce
interindividual variance. Interindividual differences
were task specific and could not be explained through
differences in stereo acuity or fixation disparity.",

that combines perceptually motivated affective
computing strategies with novel music generation. This
article presents work toward the development of one
application. The long-term goal is to develop a
responsive and adaptive system for inducing affect that
is both controlled and validated by biophysical
measures. Literature documenting perceptual responses
to music identifies a variety of musical features and
possible affective correlations, but perceptual
evaluations of these musical features for the purposes
of inclusion in a music generation system are not
readily available. A discrete feature, rhythmic density
(a function of note duration in each musical bar,
regardless of tempo), was selected because it was shown
to be well-correlated with affective responses in
existing literature. A prototype system was then
designed to produce controlled degrees of variation in
rhythmic density via a transformative algorithm. A
two-stage perceptual evaluation of a stimulus set
created by this prototype was then undertaken. First,
listener responses from a pairwise scaling experiment
were analyzed via Multidimensional Scaling Analysis
(MDS). The statistical best-fit solution was rotated
such that stimuli with the largest range of variation
were placed across the horizontal plane in two
dimensions. In this orientation, stimuli with
deliberate variation in rhythmic density appeared
farther from the source material used to generate them
than from stimuli generated by random permutation.
Second, the same stimulus set was then evaluated
according to the order suggested in the rotated
two-dimensional solution in a verbal elicitation
experiment. A Verbal Protocol Analysis (VPA) found that
listener perception of the stimulus set varied in at
least two commonly understood emotional descriptors,
which might be considered affective correlates of
rhythmic density. Thus, these results further
corroborate previous studies wherein musical parameters
are monitored for changes in emotional expression and
that some similarly parameterized control of perceived
emotional content in an affective algorithmic
composition system can be achieved and provide a
methodology for evaluating and including further
possible musical features in such a system. Some
suggestions regarding the test procedure and analysis
techniques are also documented here.",

feasible for large groups of people and pictures. In
order to get around this limitation, we present a novel

basis of our algorithm is an attention model that
combines and optimizes rectangle features with
Adaboost. The model is adapted to the characteristics
of the retina, and its input is dependent on a few
earlier fixations. This method results in significant
improvements compared to previous approaches. Our
simulation process delivers the same data structures as
an eye tracker, thus can be analyzed by standard
eye-tracking software. A comparison with recorded data
from eye tracking experiments shows that our algorithm
for simulating fixations has a very good prediction
quality for the stimulus areas on which many subjects
focus. We also compare the results with those from
earlier works. Finally, we demonstrate how the

viewer's tolerance to variation in viewing position,
perspective, and display size. These factors are also
present in stereoscopic media, where there are
additional parameters associated with the camera
arrangement (e.g., separation, orientation). The
predicted amount of depth from disparity can be
obtained trigonometrically; however, perceived depth in
complex scenes often differs from geometric predictions
based on binocular disparity alone. To evaluate the
extent and the cause of deviations from geometric
predictions of depth from disparity in naturalistic
scenes, we recorded stereoscopic footage of an indoor
scene with a range of camera separations (camera
interaxial (IA) ranged from 3 to 95 mm) and displayed
them on a range of screen sizes. In a series of
experiments participants estimated 3D distances in the
scene relative to a reference scene, compared depth
between shots with different parameters, or reproduced
the depth between pairs of objects in the scene using
reaching or blind walking. The effects of IA and screen
size were consistently and markedly smaller than
predicted from the binocular viewing geometry,
suggesting that observers are able to compensate for
the predicted distortions. We conclude that the
presence of multiple realistic monocular depth cues
drives normalization of perceived depth from binocular
disparity. It is not clear to what extent these
differences are due to cognitive as opposed to
perceptual factors. However, it is notable that these
normalization processes are not task specific; they are
evident in both perception- and action-oriented
tasks.",

different emotional conditions and explore the effect
of emotional bias on gender perception (e.g., anger

types can present different levels of physiological
cues, we also explore how two types of motion (walking
and conversations) are affected by emotional bias.
Walking typically displays more physiological cues
about gender (e.g., hip sway) and therefore is expected
to be less affected by emotional bias. To investigate
these effects, we used a corpus of captured facial and
body motions from four male and four female actors,
performing basic emotions through conversation and
walk. We expected that the appearance of the model
would also influence gender perception; therefore, we
displayed both male and female motions on two virtual
models of different sex. Two experiments were then
conducted to assess gender judgments from these
motions. In both experiments, participants were asked
to rate how male or female they considered the motions
to be under different emotional states, then classified
the emotions to determine how accurately they were
portrayed by actors. Overall, both experiments showed
that gender ratings were affected by the displayed
emotion. However, we found that conversations were
influenced by gender stereotypes to a greater extent
than walking motions. This was particularly true for
anger, which was perceived as male on both male and
female motions, and sadness, which was perceived as
less male when portrayed by male actors. We also found
a slight effect of the model when observing gender on
different types of virtual models. These results have

well as HDR ground-truth data. We found that global
ITMOs lead to the most reliable performance when
combined with a standard CAT, while more complex
methods were found to be more scene dependent, and
often less preferred than the unprocessed SDR image.
HDR color appearance models, albeit being the most
complete solutions for accurate color reproduction,
were found to not be well suited to the problem of
dynamic range expansion, suggesting that further
research may be necessary to provide accurate color

abstract = "High frame-rate (HFR) movie-making refers to the
capture and projection of movies at frame rates several
times higher than the traditional 24 frames per second.
This higher frame rate theoretically improves the
quality of motion portrayed in movies, and helps avoid
motion blur, judder, and other undesirable artifacts.
However, there is considerable debate in the cinema
industry regarding the acceptance of HFR content given
anecdotal reports of hyper-realistic imagery that
reveals too much set and costume detail. Despite the
potential theoretical advantages, there has been little
empirical investigation of the impact of high
frame-rate techniques on the viewer experience. In this
study, we use stereoscopic 3D content, filmed and
projected at multiple frame rates (24, 48, and 60 fps),
with shutter angles ranging from $ 180^\circ $ to $
358^\circ $, to evaluate viewer preferences. In a
paired-comparison paradigm, we assessed preferences
along a set of five attributes (realism, motion
smoothness, blur/clarity, quality of depth, and overall
preference). The resulting data show a clear preference
for higher frame rates, particularly when contrasting
24 fps with 48 or 60 fps. We found little impact of
shutter angle on viewers' choices, with the exception
of one measure (motion smoothness) for one clip type.
These data are the first empirical evidence of the
advantages afforded by high frame-rate capture and
presentation in a cinema context.",

the size of gaps shown in the virtual world. Foot size
affected both affordance judgments and size estimates
such that those with enlarged virtual feet estimated
they could step over larger gaps and that the extent of
the gap was smaller. Shrunken feet led to the
perception of a reduced ability to step over a gap and
smaller estimates of width. The results suggest that
people use their visually perceived foot size to scale
virtual spaces. Regardless of foot size, participants
felt that they owned the feet rendered in the virtual
world. Seeing disembodied, but motion-tracked, virtual

Although advanced interactions with computers are

convey socio-emotional information (such as emotions,
intentions, mental state, and expectations) or it will
likely be misunderstood. Here, we present a simple

are perceived from body movements is required for the
design of more effective virtual characters that behave
in a socially realistic manner. For this purpose,
realistic body motion, captured from human movements,
is being used more frequently for creating characters
with natural animations in games and entertainment.
However, it is not always clear for programmers and
designers which specific motion parameters best convey
specific information such as certain emotions,
intentions, or traits. We conducted two experiments to
investigate whether the perceived traits of actors
could be determined from their body motion, and whether
these traits were associated with their perceived
intentions. We first recorded body motions from 26
professional actors, who were instructed to move in a
``hero''-like or a ``villain''-like manner. In the
first experiment, 190 participants viewed individual
video recordings of these actors and were required to
provide ratings to the body motion stimuli along a
series of different cognitive dimensions (intentions,
attractiveness, dominance, trustworthiness, and
distinctiveness). The intersubject ratings across
observers were highly consistent, suggesting that
social traits are readily determined from body motion.
Moreover, correlational analyses between these ratings
revealed consistent associations across traits, for
example, that perceived ``good'' intentions were
associated with higher ratings of attractiveness and
dominance. Experiment 2 was designed to elucidate the
qualitative body motion cues that were critical for
determining specific intentions and traits from the
hero- and villain-like body movements. The results
revealed distinct body motions that were readily
associated with the perception of either ``good'' or
``bad'' intentions. Moreover, regression analyses
revealed that these ratings accurately predicted the
perception of the portrayed character type. These
findings indicate that intentions and social traits are
communicated effectively via specific sets of body
motion features. Furthermore, these results have
important implications for the design of the motion of
virtual characters to convey desired social
information.",

physical activity and provide motivational support.
Users' motivation can rapidly decay if the movements of
the virtual coach are too stereotyped. Kinematic
patterns generated while performing a predefined
fitness movement can elicit and help to prolong users'
interaction and interest in training. Human body
kinematics has been shown to convey various social
attributes such as gender, identity, and acted
emotions. To date, no study provides information
regarding how spontaneous emotions and personality
traits together are perceived from full-body movements.
In this article, we study how people make reliable
inferences regarding spontaneous emotional dimensions
and personality traits of human coaches from kinematic
patterns they produced when performing a fitness
sequence. Movements were presented to participants via
a virtual mannequin to isolate the influence of
kinematics on perception. Kinematic patterns of
biological movement were analyzed in terms of movement
qualities according to the effort-shape [Dell 1977]
notation proposed by Laban [1950]. Three studies were
performed to provide an analysis of the process leading
to perception: from coaches' states and traits through
bodily movements to observers' social perception.
Thirty-two participants (i.e., observers) were asked to
rate the movements of the virtual mannequin in terms of
conveyed emotion dimensions, personality traits
(five-factor model of personality), and perceived
movement qualities (effort-shape) from 56 fitness
movement sequences. The results showed high reliability
for most of the evaluated dimensions, confirming
interobserver agreement from kinematics at zero
acquaintance. A large expressive halo merging emotional
(e.g., perceived intensity) and personality aspects
(e.g., extraversion) was found, driven by perceived
kinematic impulsivity and energy. Observers'
perceptions were partially accurate for emotion
dimensions and were not accurate for personality
traits. Together, these results contribute to both the
understanding of dimensions of social perception
through movement and the design of expressive virtual
sport coaches.",

addition to these motor changes, perceptual judgments
of space can also be altered (e.g., how far can I reach

assessed perceptual judgments of space after visuomotor
adaptation, the manipulation was always a planar
spatial shift, whereas changes in body perception could
not directly be assessed. In this study, we
investigated the effects of velocity-dependent
(spatiotemporal) and spatial scaling distortions of arm
movements on space and body perception, taking
advantage of immersive virtual reality. Exploiting the
perceptual illusion of embodiment in an entire virtual
body, we endowed subjects with new spatiotemporal or
spatial 3D mappings between motor commands and their
sensory consequences. The results imply that
spatiotemporal manipulation of 2 and 4 times faster can
significantly change participants' proprioceptive
judgments of a virtual object's size without affecting
the perceived body ownership, although it did affect
the agency of the movements. Equivalent spatial
manipulations of 11 and 22 degrees of angular offset
also had a significant effect on the perceived virtual

not affect either the sense of body ownership or

derived from individual transition matrices, is related
to participants' individual differences as well as to
either their aesthetic impression or recognition of

abstract = "Designing virtual characters that are capable of
conveying a sense of personality is important for
generating realistic experiences, and thus a key goal
in computer animation research. Though the influence of
gesture and body motion on personality perception has
been studied, little is known about which attributes of
hand pose and motion convey particular personality
traits. Using the ``Big Five'' model as a framework for
evaluating personality traits, this work examines how
variations in hand pose and motion impact the
perception of a character's personality. As has been
done with facial motion, we first study hand motion in
isolation as a requirement for running controlled
experiments that avoid the combinatorial explosion of
multimodal communication (all combinations of facial
expressions, arm movements, body movements, and hands)
and allow us to understand the communicative content of
hands. We determined a set of features likely to
reflect personality, based on research in psychology
and previous human motion perception work: shape,
direction, amplitude, speed, and manipulation. Then we
captured realistic hand motion varying these attributes
and conducted three perceptual experiments to determine
the contribution of these attributes to the character's
personalities. Both hand poses and the amplitude of
hand motion affected the perception of all five
personality traits. Speed impacted all traits except
openness. Direction impacted extraversion and openness.
Manipulation was perceived as an indicator of
introversion, disagreeableness, neuroticism, and less
openness to experience. From these results, we
generalize guidelines for designing detailed hand
motion that can add to the expressiveness and
personality of characters. We performed an evaluation
study that combined hand motion with gesture and body
motion. Even in the presence of body motion, hand
motion still significantly impacted the perception of a
character's personality and could even be the dominant
factor in certain situations.",

used to edit the appearance of objects in the real
world. Based on pixel-wise modification of light
transport, previous techniques have successfully
modified static surface properties such as surface
color, dynamic range, gloss, and shading. Here, we
propose an alternative light projection technique that
adds a variety of illusory yet realistic distortions to
a wide range of static 2D and 3D projection targets.
The key idea of our technique, referred to as
(Deformation Lamps), is to project only dynamic
luminance information, which effectively activates the
motion (and shape) processing in the visual system
while preserving the color and texture of the original
object. Although the projected dynamic luminance
information is spatially inconsistent with the color
and texture of the target object, the observer's brain
automatically combines these sensory signals in such a
way as to correct the inconsistency across visual
attributes. We conducted a psychophysical experiment to
investigate the characteristics of the inconsistency
correction and found that the correction was critically
dependent on the retinal magnitude of the
inconsistency. Another experiment showed that the
perceived magnitude of image deformation produced by
our techniques was underestimated. The results ruled
out the possibility that the effect obtained by our
technique stemmed simply from the physical change in an
object's appearance by light projection. Finally, we
discuss how our techniques can make the observers
perceive a vivid and natural movement, deformation, or
oscillation of a variety of static objects, including
drawn pictures, printed photographs, sculptures with 3D
shading, and objects with natural textures including
human bodies.",

modeling of the human visual system. In the blur
discrimination experiments, just-noticeable additional
blur required to differentiate from the reference blur
level is measured. The past studies on blur
discrimination have measured the sensitivity of the
human visual system to blur using two-dimensional (2D)
test patterns. In this study, subjective tests are
performed to measure blur discrimination thresholds
using stereoscopic 3D test patterns. Specifically, how
the binocular disparity affects the blur sensitivity is
measured on a passive stereoscopic display. A passive
stereoscopic display renders the left and right eye
images in a row interleaved format. The subjects have
to wear circularly polarized glasses to filter the
appropriate images to the left and right eyes.
Positive, negative, and zero disparity values are
considered in these experiments. A positive disparity
value projects the objects behind the display screen, a
negative disparity value projects the objects in front
of the display screen, and a zero disparity value
projects the objects at the display plane. The blur
discrimination thresholds are measured for both
symmetric and asymmetric stereo viewing cases. In the
symmetric viewing case, the same level of additional
blur is applied to the left and right eye stimulus. In
the asymmetric viewing case, different levels of
additional blur are applied to the left and right eye
stimuli. The results of this study indicate that, in
the symmetric stereo viewing case, binocular disparity
does not affect the blur discrimination thresholds for
the selected 3D test patterns. As a consequence of
these findings, we conclude that the models developed
for 2D blur discrimination can be used for 3D blur
discrimination. We also show that the Weber model
provides a good fit to the blur discrimination
threshold measurements for the symmetric stereo viewing
case. In the asymmetric viewing case, the blur
discrimination thresholds decreased, and the decrease
in threshold values is found to be dominated by eye
observing the higher blur.",

little over 100 hues are resolved. The most efficient

observers used both feature-based image-quality
attributes (e.g., sharpness, illumination) and abstract
attributes, which include an interpretation of the
image features (e.g., atmosphere and naturalness). In
addition, the observers were classified into three
viewing-strategy groups differing in fixation durations

estimation rules. In both studies, the group with
medium-length fixations differed in their estimation

recent series of studies has shown that ordinary adults
untrained in art or art history, as well as young
children, can differentiate paintings by abstract
expressionists and superficially similar works by
preschool children and even animals (monkeys, apes,
elephants). Adults perform this distinction with an
accuracy rate of ~64\%, significantly higher than

as well. Using the same paintings, we show that in
~68\% of the cases the computer algorithm can
discriminate between abstract paintings and the work of
children and animals. We also applied a method that
computes the correlation between the degree of
artisticity deduced from human perception of the
paintings and the visual content of the images, and we
show significant correlation between perceived
artisticity and visual content. The image content
descriptor that was the strongest predictor of correct
identification was the fractality of the painting. We
also show that the computer algorithm predicts the

Environments (IVEs) or virtual reality within a
participant's maximum arm reach. Our goal is to
understand how physical reaching actions to the
perceived location of targets in the presence or
absence of visuo-haptic feedback are different between
real and virtual viewing conditions. Typically,
participants reach to the perceived location of objects
in the three-dimensional (3D) environment to perform
selection and manipulation actions during 3D
interaction in applications such as virtual assembly or
rehabilitation. In these tasks, participants typically
have distorted perceptual information in the IVE as
compared to the real world, in part due to
technological limitations such as minimal visual field
of view, resolution, latency, and jitter. In an
empirical evaluation, we asked the following questions:
(i) how do the perceptual differences between virtual
and real world affect our ability to accurately reach
to the locations of 3D objects, and (ii) how do the
motor responses of participants differ between the
presence or absence of visual and haptic feedback? We
examined factors such as velocity and distance of
physical reaching behavior between the real world and
IVE, both in the presence or absence of visuo-haptic
information. The results suggest that physical reach
responses vary systematically between real and virtual
environments, especially in situations involving the
presence or absence of visuo-haptic feedback. The
implications of our study provide a methodological
framework for the analysis of reaching motions for

effect, we evaluate whether increased numerical
accuracy of a propagation algorithm translates into
increased perceptual differentiation in interactive
virtual environments. Our results suggest that auditory
perception does benefit from the increased accuracy,
with subjects showing better perceptual differentiation
when experiencing the more accurate rendering method:
the diffraction experiment shows a more linearly
decaying sound field (with respect to the diffraction
angle) for the accurate diffraction method, whereas the

the first explicit study of the perception of child
motion (ages 5 to 9 years old), compared to analogous
adult motion. We used markerless motion capture to
collect an exploratory corpus of child and adult
motion, and conducted a perceptual study with point
light displays to discover whether naive viewers could
identify a motion as belonging to a child or an adult.
We find that people are generally successful at this

Although color maps are used in many disciplines and

ask ourselves the question of how to best visualize a
luminance distribution encoded in a high-dynamic-range
(HDR) image using false colors such that the resulting
visualization is the most descriptive. To this end, we
first propose a definition for descriptiveness. We then
propose a methodology to evaluate it subjectively.
Then, we propose an objective metric that correlates
well with the subjective evaluation results. Using this
metric, we evaluate several false coloring strategies
using a large number of HDR images. Finally, we conduct
a second psychophysical experiment using images
representing a diverse set of scenes. Our results
indicate that the luminance compression method has a
significant effect and the commonly used logarithmic
compression is inferior to histogram equalization.
Furthermore, we find that the default color scale of
the Radiance global illumination software consistently
performs well when combined with histogram
equalization. On the other hand, the commonly used

contrast in accordance with the incident veiling
luminance. As the glare expires, the contrast starts to
normalize smoothly over time. The conversion of glare
parameters and elapsed time into image contrast during

Previous works suggested a possible dominance of the
visual over the auditory modality in this situation.
The main goal of the present study is to examine the
interferences between these modalities in visual,
audio, and audio-visual target acquisition tasks.
Experiments are based on a movement replication
paradigm, where a subject controls a cursor on a screen
or the pitch of a synthesized sound by changing the
stylus position on a covered graphic tablet. The
experiments consisted of the following tasks: (1) a
target acquisition task that was aimed at a visual
target (reaching a cue with the cursor displayed on a
screen), an audio target (reaching a reference note by
changing the pitch of the sound played in headsets), or
an audio-visual target, and (2) the replication of the
target acquisition movement in the opposite direction.
In the return phase, visual and audio feedback were
suppressed. Different gain factors perturbed the
relationships among the stylus movements, visual cursor
movements, and audio pitch movements. The deviations
between acquisition and return movements were analyzed.
The results showed that hand amplitudes varied in
accordance with visual, audio, and audio-visual
perturbed gains, showing a larger effect for the visual
modality. This indicates that visual, audio, and
audio-visual actions interfered with the motor modality
and confirms the spatial representation of pitch
reported in previous studies. In the audio-visual
situation, vision dominated over audition, as the
latter had no significant influence on motor movement.
Consequently, visual feedback is helpful for musical
targeting of pitch on a graphic tablet, at least during
the learning phase of the instrument. This result is
linked to the underlying spatial organization of pitch
perception. Finally, this work brings a complementary
approach to previous studies showing that audition may
dominate over vision for other aspects of musical sound
(e.g., timing, rhythm, and timbre).",

practitioners often observe that basic implementations
of virtual walking, in which head-tracked movements are
mapped isometrically to a VE are not estimated as
entirely natural. Instead, users estimate a virtual
walking velocity as more natural when it is slightly
increased compared to the users physical body movement.
In this article, we investigate the effects of such
nonisometric mappings between physical movements and
virtual motions in the VE on walking velocity and
biomechanics of the gait cycle. Therefore, we performed
an experiment in which we measured and analyzed
parameters of the biomechanics of walking under
conditions with isometric as well as nonisometric
mappings. Our results show significant differences in
most gait parameters when walking in the VE in the
isometric mapping condition compared to the
corresponding parameters in the real world. For
nonisometric mappings we found an increased divergence
of gait parameters depending on the velocity of visual

abstract = "Contemporary game engines offer an outstanding
graphics quality but they are not free from visual
artifacts. A typical example is aliasing, which,
despite advanced antialiasing techniques, is still
visible to the game players. Essential deteriorations
are the shadow acne and peter panning responsible for
deficiency of the shadow mapping technique. Also
Z-fighting, caused by the incorrect order of drawing
polygons, significantly affects the quality of the
graphics and makes the gameplay more difficult. In this
work, we propose a technique, in which visibility of
deteriorations is uncovered by the objective image
quality metrics (IQMs). We test the efficiency of a
simple mathematically based metric and advanced IQMs: a
Spatial extension of CIELAB (S-CIELAB), the Structural
SIMilarity Index (SSIM), the Multiscale Structural
SIMilarity Index (MS-SSIM), and the High Dynamic Range
Visual Difference Predictor-2 (HDR-VDP-2).
Additionally, we evaluate the Color Image Difference
(CID) metric, which is recommended to detect the
differences in colors. To find out which metric is the
most effective for the detection of the game engine
artifacts, we build a database of manually marked
images with representative set of artifacts. We conduct
subjective experiments in which people manually mark
the visible local artifacts in the screenshots from the
games. Then the detection maps averaged over a number
of observers are compared with results generated by
IQMs. The obtained results show that SSIM and MS-SSIM
metrics outperform other techniques. However, the
results are not indisputable, because, for small and
scattered aliasing artifacts, HDR-VDP-2 metrics report
the results most consistent with the average human
observer. As a proof of concept, we propose an
application in which resolution of the shadow maps is
controlled by the SSIM metric to avoid perceptually
visible aliasing artifacts on the shadow edges.",

appearance. A system that could intuitively manipulate
and design fabric texture and color would be a very
powerful tool. This article presents an interactive
fabric appearance design system that modulates the
texture patterns of input fabric example images and
transfers the color patterns from other input images
onto them. For this purpose, we propose a method to
synthesize a natural texture image based on our
findings from subjective experiments: (1) intensity and
its deviation of two input images are significantly
related to the realistic appearance of synthesized
textures and (2) the spatial-frequency and edge
intensity of two different input images significantly
influence the natural appearance of synthesized texture
perception. In our procedure, first, the texture
pattern of an input fabric image is modulated in terms
of undulation, thickness, and roughness. Next, we
transfer the color pattern of an original color image
onto the modulated texture pattern in the YIQ color
space. To perform this color transfer, we use the IQ
component of the color image. To reduce the unnatural
appearance of the output color-transfer image, we
remove the high-frequency components of the original
color image. In addition, the Y component of the
color-transfer image is obtained by adding the
deviation of the texture pattern Y component to the
texture pattern of the color image. These algorithms
for reducing unnaturalness and synthesizing images were
developed based on our findings from several subjective
experiments on natural appearance. Finally, we
implemented our algorithm on a smart device. Our system
allows us to interactively design the texture and color
of fabric by using images.",

used to generate a stimulus set of short pieces of

ascribed a two-dimensional valence-arousal coordinate

initially drawn from the literature, was subsequently
adjusted by amplifying or attenuating the quantity of
each feature in order to maximize the spread of stimuli
in the valence-arousal space before a second listener
evaluation was conducted. This process was repeated a
third time in order to maximize the spread of
valence-arousal coordinates ascribed to the generated
stimulus set in comparison to a spread taken from an

in the surrounding environment is acknowledged to be
one of the first perceptual tasks developed by humans,

might be based on rather simple motion properties, and
it can be interpreted as an atomic building block of
more complex perception tasks typical of interacting
scenarios, as the understanding of non-verbal

of others' action goals. In this article, we propose a
novel perspective for video analysis, bridging
cognitive science and machine vision, which leverages
the use of computational models of the perceptual

perception in humans. Our work offers different
contributions. In a first part, we propose an empirical
formulation for the Two-Thirds Power Law, a well-known
invariant law of human movement, and thoroughly discuss
its readability in experimental settings of increasing
complexity. In particular, we consider unconstrained
video analysis scenarios, where, to the best of our
knowledge, the invariant law has not found application
so far. The achievements of this analysis pave the way
for the second part of the work, in which we propose
and evaluate a general representation scheme for
biological motion characterisation to discriminate
biological movements with respect to non-biological

on the well-known degradation of peripheral visual
acuity. It reduces computational costs by showing a
high-quality image in the user's central (foveal)

Foveated rendering is a promising optimization for
Virtual Reality (VR) graphics, and generally requires
accurate and low-latency eye tracking to ensure
correctness even when a user makes large, fast eye
movements such as saccades. However, due to the
phenomenon of saccadic omission, it is possible that
these requirements may be relaxed. In this article, we
explore the effect of latency for foveated rendering in
VR applications. We evaluated the detectability of
visual artifacts for three techniques capable of
generating foveated images and for three different
radii of the high-quality foveal region. Our results
show that larger foveal regions allow for more
aggressive foveation, but this effect is more
pronounced for temporally stable foveation techniques.
Added eye tracking latency of 80--150ms causes a
significant reduction in acceptable amount of
foveation, but a similar decrease in acceptable
foveation was not found for shorter eye-tracking
latencies of 20--40ms, suggesting that a total system

Our metric utilizes multi-exposed virtual photographs

distortion, visual saliency distortion, and detail
distortion in light and dark areas, the metric measures
the overall perceptual distortion and assigns a score

reality has been a persistent concern for almost 20
years. Modern head-mounted displays (HMDs) appear to
have begun to ameliorate underperception. The current
study examined several aspects of perceived space in
the HTC Vive. Blind-walking distance judgments, verbal
distance judgments, and size judgments were measured in
two distinct virtual environments (VEs)-a high-quality
replica of a real classroom and an empty grass field-as
well as the real classroom upon which the classroom VE
was modeled. A brief walking interaction was also
examined as an intervention for improving anticipated
underperception in the VEs. Results from the Vive were
compared to existing data using two older HMDs (nVisor
SX111 and ST50). Blind-walking judgments were more
accurate in the Vive compared to the older displays,
and did not differ substantially from the real world
nor across VEs. Size judgments were more accurate in
the classroom VE than the grass VE and in the Vive
compared to the older displays. Verbal judgments were
significantly smaller in the classroom VE compared to
the real classroom and did not significantly differ
across VEs. Blind-walking and size judgments were more
accurate after walking interaction, but verbal
judgments were unaffected. The results indicate that
underperception of distance in the HTC Vive is less
than in older displays but has not yet been completely
resolved. With more accurate space perception afforded
by modern HMDs, alternative methods for improving
judgments of perceived space-such as walking
interaction-may no longer be necessary.",

they swiped their finger in rapid succession over a

size judgments increased after walking interaction, and
the improvement was larger for distance than for size
judgments. After walking interaction, distance

abstract = "Robotic-assisted surgeries are commonly used today as
a more efficient alternative to traditional surgical
options. Both surgeons and patients benefit from those
systems, as they offer many advantages, including less
trauma and blood loss, fewer complications, and better
ergonomics. However, a remaining limitation of
currently available surgical systems is the lack of
force feedback due to the teleoperation setting, which
prevents direct interaction with the patient. Once the
force information is obtained by either a sensing
device or indirectly through vision-based force
estimation, a concern arises on how to transmit this
information to the surgeon. An attractive alternative
is sensory substitution, which allows transcoding
information from one sensory modality to present it in
a different sensory modality. In the current work, we
used visual feedback to convey interaction forces to
the surgeon. Our overarching goal was to address the
following question: How should interaction forces be
displayed to support efficient comprehension by the
surgeon without interfering with the surgeon's
perception and workflow during surgery? Until now, the
use the visual modality for force feedback has not been
carefully evaluated. For this reason, we conducted an
experimental study with two aims: (1) to demonstrate
the potential benefits of using this modality and (2)
to understand the surgeons' perceptual preferences. The
results derived from our study of 28 surgeons revealed
a strong positive acceptance of the users (96\%) using
this modality. Moreover, we found that for surgeons to
easily interpret the information, their mental model
must be considered, meaning that the design of the
visualizations should fit the perceptual and cognitive
abilities of the end user. To our knowledge, this is
the first time that these principles have been analyzed
for exploring sensory substitution in medical robotics.
Finally, we provide user-centered recommendations for
the design of visual displays for robotic surgical
systems.",

experiment, we find that humans are highly consistent
in their responses when given a pair of vertices on a

perceive to be more soft. This motivates us to take a
crowdsourcing and machine learning framework. We
collect crowdsourced data for such pairs of vertices.
We then combine a learning-to-rank approach and a
multi-layer neural network to learn a non-linear
softness measure mapping any vertex to a softness
value. For a new 3D shape, we can use the learned
measure to compute the relative softness of every
vertex on its surface. We demonstrate the robustness of
our framework with a variety of 3D shapes and compare
our non-linear learning approach with a linear method

To bridge this gap, this article presents an experiment
analyzing the behavioral disparity between human
locomotion being performed without any equipment and in
immersive VR while wearing a head-mounted display
(HMD). The presented study ( n = 30) is split up in
three sections and covers linear walking, non-linear
walking, and obstacle avoidance. Special care has been
given to design the experiment so that findings are
generally valid and can be applied to a wide range of
domains beyond the manufacturing industry. The findings
provide novel insights into the effect of immersive VR
on specific gait parameters. In total, a comprehensive
sample of 18.09km is analyzed. The results reveal that
the HMD had a medium effect (up to 13\%) on walking
velocity, on non-linear walking toward an oriented
target, and on clearance distance. The overall
differences are modeled using multiple regression
models, thus allowing the general usage within various
domains. Summarizing, it can be concluded that VR can
be used to analyze and plan human locomotion; however,
specific details may have to be adjusted to transfer

distance estimation behavior, a standard indirect blind
walking task was used. An Oculus Rift DK1, weighted
Oculus Rift DK1, Oculus Rift DK1 with an artificially

these factors on distance underestimation; the other
systems were evaluated because they are popular systems
that are widely available. We found that weight and
field of view restrictions heightened underestimation
in the Rift DK1. Results from these conditions were
comparable to the Nvis SX60 and SX111. The Oculus Rift
DK1 and CV1 possessed the least amount of distance

evidence that affective dimensions are a natural way to

engineering parameters of hypothesized relevance.
Results from two user studies show that an automatable
algorithm can increase a vibration's perceived
agitation and liveliness to different degrees via
signal energy, while increasing its discontinuity or

reality context. Here, foveated rendering is a
promising approach for reducing the number of shaded

radiance through lenses. The lenses create
depth-of-field (DoF) effects when accommodated to
objects at varying distances. The central idea of this

method to conceal rendering artifacts. To showcase the
potential of such filters, we present a foveated

animated avatars by combining the shape and motion
estimates from either a single performer or from
different performers. Using these stimuli we conducted
three experiments in an immersive virtual reality
environment. First, a group of participants detected
which of two stimuli was inconsistent. Performance was
very low, and results were only marginally significant.
Next, a second group of participants rated perceived
attractiveness, eeriness, and humanness of consistent
and inconsistent stimuli, but these judgements of
animation characteristics were not affected by
consistency of the stimuli. Finally, a third group of
participants rated properties of the objects rather
than of the performers. Here, we found strong
influences of shape-motion inconsistency on perceived
weight and thrown distance of objects. This suggests
that the visual system relies on its knowledge of shape
and motion and that these components are assimilated
into an altered perception of the action outcome. We
propose that the visual system attempts to resist
inconsistent interpretations of human animations.
Actions involving object manipulations present an
opportunity for the visual system to reinterpret the
introduced inconsistencies as a change in the dynamics
of an object rather than as an unexpected combination
of body shape and body motion.",

abstract = "The classic rubber hand illusion (RHI) experiment
studies the sense of embodiment over a fake limb.
Distinguished subcomponents of embodiment are ownership
(sense of self-attribution of a body), agency (sense of
having motor control), and self-location (the spatial
experience of being inside a body), and are typically
evoked in either reality or virtual reality. In
augmented reality (AR), however, visually present real
limbs can be augmented with (multiple) fake virtual
limbs, which results in a variation of the RHI, the
augmented reality supernumerary hand illusion (ARSHI).
Such conditions occur, for example, in first-person AR
games and in AR-interfaces for tele-robotics. In this
article, we examined to what extent humans can
experience the sense of embodiment over a supernumerary
virtual arm in addition to one or two real arms. We
also examine how embodiment is affected by the
perceptual visual-tactile synchronicity of the virtual
and real limbs, and by the synchronicity of active
movement of the virtual and real hand. Embodiment was
measured subjectively by questionnaire and objectively
by skin conductance responses (SCRs). Questionnaire
responses show that ownership, agency, and
self-location can be evoked over the virtual arm in the
presence of a real arm, and that they are significantly
stronger for synchronous conditions than for
asynchronous conditions. The perceptual and motorical
synchronous condition with three visible hands led to
an experience of owning the virtual hand. These
responses further show that agency was also strongly
experienced over the supernumerary virtual arm, and
responses regarding self-location suggest a shift in
sensed location when one real arm was in view and an
additional location when both real arms where in view.
SCRs show no significant effect of condition, but do
show a significant habituation effect as a function of
the number of conditions performed by participants.
When analyzing the relations at the individual
participant level between the questionnaire data and
skin conductance, we found two clusters of
participants: (1) participants with low questionnaire
responses and low-medium SCRs and (2) participants with
high questionnaire responses and low-high SCRs.
Finally, we discuss how virtual hand appearance/realism
and willingness to accept virtual limbs could play an
important role in the ARSHI, and provide insights on
intricacies involved with measuring and evaluating
RHIs.",

there is a need to investigate the effect of
photorealism on users' perception, particularly for
interactive, emotional scenarios in VR. In this
article, we explored three main topics, where we
predicted photorealism will make a difference: the
illusion of being present with the virtual person and
in an environment, altered emotional response toward
the character, and a subtler response-comfort of being
in close proximity to the character. We present a
perceptual experiment, with an interactive expressive
virtual character in VR, which was designed to induce
particular social responses in people. Our participant
pool was large (N = 797) and diverse in terms of
demographics. We designed a between-group experiment,
where each group saw either the realistic rendering or
one of our stylized conditions (simple and sketch
style), expressing one of three attitudes: Friendly,
Unfriendly, or Sad. While the render style did not
particularly effect the level of comfort with the
character or increase the illusion of presence with it,
our main finding shows that the photorealistic
character changed the emotional responses of
participants, compared to the stylized versions. We
also found a preference for realism in VR, reflected in
the affinity and higher place illusion in the scenario,

walking animations driven by six different
representations of human movement using a graphics
Turing test. All six representations are based on
movement primitives (MPs), which are predictive models
of full-body movement that differ in their complexity
and prediction mechanism. Assuming that humans are
experts at perceiving biological movement from noisy
sensory signals, it follows that these percepts should
be describable by a suitably constructed Bayesian ideal
observer model. We build such models from MPs and
investigate if the perceived naturalness of human
animations are predictable from approximate Bayesian
model scores of the MPs. We found that certain MP-based
representations are capable of producing movements that
are perceptually indistinguishable from natural
movements. Furthermore, approximate Bayesian model
scores of these representations can be used to predict
perceived naturalness. In particular, we could show
that movement dynamics are more important for perceived

abstract = "Head-mounted displays cause discomfort. This is
commonly attributed to conflicting depth cues, most
prominently between vergence, which is consistent with
object depth, and accommodation, which is adjusted to
the near eye displays. It is possible to adjust the
camera parameters, specifically interocular distance
and vergence angles, for rendering the virtual
environment to minimize this conflict. This requires
dynamic adjustment of the parameters based on object
depth. In an experiment based on a visual search task,
we evaluate how dynamic adjustment affects visual
comfort compared to fixed camera parameters. We collect
objective as well as subjective data. Results show that
dynamic adjustment decreases common objective measures
of visual comfort such as pupil diameter and blink rate
by a statistically significant margin. The subjective
evaluation of categories such as fatigue or eye
irritation shows a similar trend but was inconclusive.
This suggests that rendering with fixed camera
parameters is the better choice for head-mounted
displays, at least in scenarios similar to the ones
used here.",

abstract = "Virtual environments for gaming and simulation provide
dynamic and adaptive experiences, but, despite advances
in multisensory interfaces, these are still primarily
visual experiences. To support real-time dynamic
adaptation, interactive virtual environments could
implement techniques to predict and manipulate human
visual attention. One promising way of developing such
techniques is to base them on psychophysical
observations, an approach that requires a sound
understanding of visual attention allocation.
Understanding how this allocation of visual attention
changes depending on a user's task offers clear
benefits in developing these techniques and improving
virtual environment design. With this aim, we
investigated the effect of task on visual attention in
interactive virtual environments. We recorded fixation
data from participants completing freeview, search, and
navigation tasks in three different virtual
environments. We quantified visual attention
differences between conditions by identifying the
predictiveness of a low-level saliency model and its
corresponding color, intensity, and orientation
feature-conspicuity maps, as well as measuring fixation
center bias, depth, duration, and saccade amplitude.
Our results show that task does affect visual attention
in virtual environments. Navigation relies more than
search or freeview on intensity conspicuity to allocate
visual attention. Navigation also produces fixations
that are more central, longer, and deeper into the
scenes. Further, our results suggest that it is
difficult to distinguish between freeview and search
tasks. These results provide important guidance for
designing virtual environments for human interaction,
as well as identifying future avenues of research for
developing ``attention-aware'' virtual worlds.",

they simply merge endpoints that are near each other,
thus ignoring the fact that different vertices may be
represented by different (but close) junctions and that
the endpoints of lines that depict edges that share a

abstract = "Scene recognition is an essential component of both
machine and biological vision. Recent advances in
computer vision using deep convolutional neural
networks (CNNs) have demonstrated impressive
sophistication in scene recognition, through training
on large datasets of labeled scene images (Zhou et al.
2018, 2014). One criticism of CNN-based approaches is
that performance may not generalize well beyond the
training image set (Torralba and Efros 2011), and may
be hampered by minor image modifications, which in some
cases are barely perceptible to the human eye
(Goodfellow et al. 2015; Szegedy et al. 2013). While
these ``adversarial examples'' may be unlikely in
natural contexts, during many real-world visual tasks
scene information can be degraded or limited due to
defocus blur, camera motion, sensor noise, or occluding
objects. Here, we quantify the impact of several image
degradations (some common, and some more exotic) on
indoor/outdoor scene classification using CNNs. For
comparison, we use human observers as a benchmark, and
also evaluate performance against classifiers using
limited, manually selected descriptors. While the CNNs
outperformed the other classifiers and rivaled human
accuracy for intact images, our results show that their
classification accuracy is more affected by image
degradations than human observers. On a practical
level, however, accuracy of the CNNs remained well
above chance for a wide range of image manipulations
that disrupted both local and global image statistics.
We also examine the level of image-by-image agreement
with human observers, and find that the CNNs' agreement
with observers varied as a function of the nature of
image manipulation. In many cases, this agreement was
not substantially different from the level one would
expect to observe for two independent classifiers.
Together, these results suggest that CNN-based scene
classification techniques are relatively robust to
several image degradations. However, the pattern of
classifications obtained for ambiguous images does not
appear to closely reflect the strategies employed by
human observers.",

abstract = "HTTP-based Adaptive Streaming (HAS) is the dominant
Internet video streaming application. One specific HAS
approach, Dynamic Adaptive Streaming over HTTP (DASH),
is of particular interest, as it is a widely deployed,
standardized implementation. Prior academic research
has focused on networking and protocol issues, and has
contributed an accepted understanding of the
performance and possible performance issues in large
deployment scenarios. Our work extends the current
understanding of HAS by focusing directly on the
impacts of choice of the video quality adaptation
algorithm on end-user perceived quality. In congested
network scenarios, the details of the adaptation
algorithm determine the amount of bandwidth consumed by
the application as well as the quality of the rendered
video stream. HAS will lead to user-perceived changes
in video quality due to intentional changes in quality
video segments, or unintentional perceived quality
impairments caused by video decoder artifacts such as
pixelation, stutters, or short or long stalls in the
rendered video when the playback buffer becomes empty.
The HAS adaptation algorithm attempts to find the
optimal solution to mitigate the conflict between
avoiding buffer stalls and maximizing video quality. In
this article, we present results from a user study that
was designed to provide insights into ``best practice
guidelines'' for a HAS adaptation algorithm. Our
findings suggest that a buffer-based strategy might
provide a better experience under higher network
impairment conditions. For the two network scenarios
considered, the buffer-based strategy is effective in
avoiding stalls but does so at the cost of reduced
video quality. However, the buffer-based strategy does
yield a lower number of quality switches as a result of
infrequent bitrate adaptations. Participants in
buffer-based strategy do notice the drop in video
quality causing a decrease in perceived QoE, but the
perceived levels of video quality, viewer frustration,
and opinions of video clarity and distortion are
significantly worse due to artifacts such as stalls in
capacity-based strategy. The capacity-based strategy
tries to provide the highest video quality possible but
produces many more artifacts during playback. The
results suggest that player video quality has more of
an impact on perceived quality when stalls are
infrequent. The study methodology also contributes a
unique method for gathering continuous quantitative
subjective measure of user perceived quality using a
Wii remote.",
