Outline of Final Research Achievements

The purpose of this study is to elucidate a Redirected Interaction (RDI) method that enables physical interaction among multiple users by applying Redirected Walking (RDW). To achieve this, we developed an RDI method using vector potentials to preserve the position and orientation relationships between users under RDW. Furthermore, regarding interactions between users and dynamic objects, which are challenging with the RDI method alone, we constructed a system that presents objects of arbitrary shapes at arbitrary locations under RDI using automated guided vehicles. The effectiveness of RDI for dynamic objects was verified through user studies.
