A study on redirection method based on pitch direction manipulation in VR environments

Abstract

This study is about viewpoint pitch manipulation in pitch direction during redirected walking. Gait will be changed during walking uphill has been reported in many research. In this study, it is assumed that similar gait change will also occur in virtual reality (VR) environment due to viewpoint manipulation in pitch direction. In the experiment, we investigated the changes in gait speed and head angle during dynamic viewpoint manipulation within a 5-meter walking interval, as well as the perceived threshold, which is the effect range of viewpoint manipulation. The analysis results show the changes which walking speed and the effective range of viewpoint manipulation, indicating that viewpoint manipulation in pitch direction is an effective method for redirected walking.
