A redirected walking (RDW) techniques enable users to walk around infinite virtual environments (VEs) in a finite physical space. In previous studies on RDW, many researchers have discussed manipulations in the yaw direction, but few have tackled with redirection in pitch and roll directions. We propose a novel VR system, which realizes pitch and roll redirections and allows users to experience walking on the 3D model of Mobius Strip in the VE.
