Editorial: Walking in real and virtual environments
Adar Pelah, Jan J. Koenderink
Article No.: 1
DOI: 10.1145/1227134.1227135

Obstacle avoidance during walking in real and virtual environments
Philip W. Fink, Patrick S. Foo, William H. Warren
Article No.: 2
DOI: 10.1145/1227134.1227136

Immersive virtual environments are a promising research tool for the study of perception and action, on the assumption that visual--motor behavior in virtual and real environments is essentially similar. We investigated this issue for locomotor...

Estimation of travel distance from visual motion in virtual environments
Harald Frenz, Markus Lappe, Marina Kolesnik, Thomas Bührmann
Article No.: 3
DOI: 10.1145/1227134.1227137

Distance estimation of visually simulated self-motion is difficult, because one has to know or make assumptions about scene layout to judge ego speed. Discrimination of the travel distances of two sequentially simulated self-motions in the same...

Calibration of locomotion resulting from visual motion in a treadmill-based virtual environment
Betty J. Mohler, William B. Thompson, Sarah H. Creem-Regehr, Peter Willemsen, Herbert L. Pick, Jr., John J. Rieser
Article No.: 4
DOI: 10.1145/1227134.1227138

This paper describes the use of a treadmill-based virtual environment (VE) to investigate the influence of visual motion on locomotion. First, we establish that a computer-controlled treadmill coupled with a wide field of view computer graphics...

Step frequency and perceived self-motion
Frank H. Durgin, Catherine Reed, Cara Tigue
Article No.: 5
DOI: 10.1145/1227134.1227139

There is a discrepancy between the ability to correctly match the gains of visual and motor speed in virtual reality (VR) when walking on solid ground and the failure of this ability when walking on a treadmill. Moreover, this discrepancy has been...

Gender differences in cue preference during path integration in virtual environments
Francesca C. Fortenbaugh, Sidhartha Chaudhury, John C. Hicks, Lei Hao, Kathleen A. Turano
Article No.: 6
DOI: 10.1145/1227134.1227140

Three studies were conducted to examine whether men and women differ in how they recalibrate their path-integration systems when walking without vision in virtual environments. Distance cues provided by a scene and a tone, which ended each trial,...

A feedback-controlled interface for treadmill locomotion in virtual environments
Lee Lichtenstein, James Barabas, Russell L. Woods, Eli Peli
Article No.: 7
DOI: 10.1145/1227134.1227141

Virtual environments (VEs) allow safe, repeatable, and controlled evaluations of obstacle avoidance and navigation performance of people with visual impairments using visual aids. Proper simulation of mobility in a VE requires an interface, which...

Heading assessment by “tunnel vision” patients and control subjects standing or walking in a virtual reality environment
Henry Apfelbaum, Adar Pelah, Eli Peli
Article No.: 8
DOI: 10.1145/1227134.1227142

Virtual reality locomotion simulators are a promising tool for evaluating the effectiveness of vision aids to mobility for people with low vision. This study examined two factors to gain insight into the verisimilitude requirements of the test...
