A Luminance-aware Model of Judder Perception
ACM Transactions on Graphics (TOG), Volume 38, Issue 5Article No.: 142, Pages 1–10https://doi.org/10.1145/3338696The perceived discrepancy between continuous motion as seen in nature and frame-by-frame exhibition on a display, sometimes termed judder, is an integral part of video presentation. Over time, content creators have developed a set of rules and ...

Can we perceive changes in our moving speed: a comparison between directly and indirectly powering the locomotion in virtual environments
VRST '18: Proceedings of the 24th ACM Symposium on Virtual Reality Software and TechnologyArticle No.: 36, Pages 1–10https://doi.org/10.1145/3281505.3281510Many categories of the illusion of self-motion have been widely studied with the potential support of virtual reality. However, the effects of directly and indirectly powering the movement on the possibility of perceiving changes in moving speed and ...

Perceptual Constancy in the Reproduction of Virtual Tactile Textures With Surface Displays
ACM Transactions on Applied Perception (TAP), Volume 15, Issue 2Article No.: 10, Pages 1–12https://doi.org/10.1145/3152764For very rough surfaces, friction-induced vibrations contain frequencies that change in proportion to sliding speed. Given the poor capacity of the somatosensory system to discriminate frequencies, this fact raises the question of how accurately finger ...

The influence of step frequency on the range of perceptually natural visual walking speeds during walking-in-place and treadmill locomotion
VRST '14: Proceedings of the 20th ACM Symposium on Virtual Reality Software and TechnologyPages 187–190https://doi.org/10.1145/2671015.2671113Walking-In-Place (WIP) techniques make relatively natural walking experiences within immersive virtual environments possible when the physical interaction space is limited in size. In order to facilitate such experiences it is necessary to establish a ...

Establishing the Range of Perceptually Natural Visual Walking Speeds for Virtual Walking-In-Place Locomotion
IEEE Transactions on Visualization and Computer Graphics (ITVC), Volume 20, Issue 4Pages 569–578https://doi.org/10.1109/TVCG.2014.21Walking-In-Place (WIP) techniques make it possible to facilitate relatively natural locomotion within immersive virtual environments that are larger than the physical interaction space. However, in order to facilitate natural walking experiences one ...

Active Control With an Isoluminant Display
IEEE Transactions on Systems, Man, and Cybernetics, Part A: Systems and Humans (TSMCPA), Volume 36, Issue 6Pages 1124–1134https://doi.org/10.1109/TSMCA.2006.878951Humans perceive isoluminant visual stimuli (i.e., stimuli that show little or no luminance variation across space) to move more slowly than their luminance-defined counterparts. To explore whether impaired motion perception at isoluminance also affects ...

Moving objects appear to slow down at low contrasts
Neural Networks (NENE), Volume 16, Issue 5-6Pages 933–938https://doi.org/10.1016/S0893-6080(03)00111-4Moving cars give the illusion of slowing down in foggy conditions, because low contrast reduces perceived speed. A grey square that drifts horizontally across a surround of black and white vertical stripes appears to stop and start as it crosses each ...

Mapping the physical world to psychological reality: creating synthetic environments
DIS '00: Proceedings of the 3rd conference on Designing interactive systems: processes, practices, methods, and techniquesPages 203–207https://doi.org/10.1145/347642.347717The successful creation of telepresence and virtual environments requires a change in design paradigm. We must move away from attempts to recreate reality in its entirety toward the creation of environments that are psychologically real for humans, ...
