Abstract
This study aims to use the redirected walking technique that makes users of virtual reality systems feel like they are walking on an inclined surface while actually walking on a flat one in a real space. However, when the appearance of the virtual inclination becomes too significant, the absence of rotational force components applied to the body causes a feeling of incongruity. In this paper, we propose a novel technique to effectively manipulate the perception of inclination of a virtual walking surface using haptic cues to complement the rotational force components. Based on this approach, we developed a system to generate the rotational force components by loading a weight at the user’s back, which shifts when the configuration of virtual inclination changes. The experiments conducted using the proposed system verified the feasibility of our approach.
