PDF: Estimation of Detection Thresholds for Redirected Turning

Abstract

Redirection makes it possible to walk around a vast virtual space in a limited real space while providing a natural walking sensation by applying a gain to the amount of movement in a real space. However, manipulating the walking path while keeping it and maintaining the naturalness of walking when turning at a corner cannot be achieved by the existing methods. To realize natural manipulation for turning at a corner, this study proposes novel “turning gains”, which refer to the increase in real and virtual turning degrees. The result of an experiment which aims to estimate the detection thresholds of turning gains indicated that when the turning radius is 0.5 m, discrimination is more difficult compared with the rotation gains (r = 0.0m).
