Walking real space for move in virtual environment is one of methods for improve immersion of Virtual Reality (VR) contents. However, a movable space in virtual environment is limited by real space obstacles such as walls. As a result, an experience of the VR content may be impaired. One solution of this problem is Redirected Walking (RDW). RDW is a method for enabling walk on virtual space that larger than limited real space. The method led to an illusion of walking direction by rotation of virtual scene. Previous research has indicated that haptics can be enhance a level of illusion. In this study, we propose a RDW method combining traction force presentation with virtual scene rotation. We develop a RDW system that presents traction force as the subject walks, and conducted experiments with few subjects. Result of experiment suggests possibility of enhancing an illusion level by traction force presentation.
