Proceedings IEEE Virtual Reality 2002  
How significant are these distortions for spatial perception in virtual reality?  ...  Typically, for the display to be judged as stable, subjects needed the visual world to be moved in the opposite direction of the head movement by an amount greater than the head movement itself, during  ...  Virtual reality (VR) head tracking systems are typically referenced to the head and the actual position and orientation of the eyes can only be approximated from the head tracking data.  ...

Sensorimotor Adaptation Training's Effect on Head Stabilization in Response to a Lateral Perturbation in Older Adults

Regina R. Buccello-Stout, Ronita L. Cromwell, Jacob J. Bloomberg, Elbert B. Whorton
2013 Journal of Aging and Physical Activity  
Given the rehabilitative use of virtual reality to train sensorimotor systems, we wanted to use virtual reality as a mechanism to train sensorimotor adaptability of head stability in older adults.  ...  It would appear that the exposure to the perceptual-motor discordance during training resulted in the adaptation of the more body-centered head-stabilization strategy.  ...

Controlled interaction: Strategies for using virtual reality to study perception

Frank H. Durgin, Zhi Li
2010 Behavior Research Methods  
Immersive virtual reality systems employing head-mounted displays offer great promise for the investigation of perception and action, but there are well-documented limitations to most virtual reality systems  ...  New data concerning the effect of pincushion distortion on the perception of surface orientation are presented as well as data documenting the perception of dynamic distortions associated with head movements  ...  To confirm our subjective impressions that pincushion correction caused perceptual instability during head motions, we also collected ratings of stability.  ...

Latency and User Performance in Virtual Environments and Augmented Reality

Stephen R. Ellis
2009 2009 13th IEEE/ACM International Symposium on Distributed Simulation and Real Time Applications  
Latency has been shown to reduce the user's sense of immersion within a virtual environment, disturb user interaction with virtual objects, and to contribute to motion sickness during some simulation tasks  ...  System rendering latency has been recognized by senior researchers, such as Professor Fredrick Brooks of UNC (Turing Award 1999), as a major factor limiting the realism and utility of head-referenced displays  ...  In particular the tuning of a simple extrapolative predictive filter not using a dynamic movement model will be presented.  ...

Tandem Walk in Simulated Martian Gravity and Visual Environment [article]

Marissa J Rosenberg, Matthew Koslovsky, Matthew Noyes, Millard F Reschke, Gilles Clement
2022 bioRxiv   pre-print
Four conditions were investigated: (a) 1 G in virtual reality (VR); (b) 1 G in VR with a superimposed disorienting optokinetic simulation (VR+DOS); (c) 0.38 G in VR; and (d) 0.38 G in VR+DOS.  ...  The increased tandem walking performance in 0.38 G compared to 1 G was presumably due to an increased cone of stability, allowing larger amplitude of body sway without resulting in a fall.  ...  A virtual reality environment simulated the astronauts' postflight illusory movements caused by head movements.  ...
