Abstract
When walking in Virtual Environments, ‘Redirected Walking' is often used to extend the virtual walking range beyond the physical borders of the tracking system. To investigate the effect of walking speed on curve sensitivity, an experiment was conducted in which the participants walked on curved paths at different walking speeds and gave response of which direction they have walked on a curve. An effect of lowered detection thresholds of curvature has been found for the slower walking speed. Another possible way to redirect users could be to use avatars in order to exploit collision- avoiding behaviour as it is applied by humans in everyday life when passing people. To evaluate these effects, we first had to develop a free-walking controller for redirected walking and extend it by adding avatars as distractors. A dynamic curvature controller (speed as a parameter) and avatar controller were evaluated in a further experiment which showed significant improvements for dynamic curvature adjustment. Furthermore we gained insight into how to use avatars as distracters for improving redirected walking.
