Walking Support in Real Space Using Social Force Model When Wearing Immersive HMD

Due to advances in tracking technology, wireless technology and battery capacity for Head Mounted Displays (HMD), user's are capable not only of overlooking a virtual space while sitting on a chair, but also to play in Virtual Reality (VR) more dynamically while walking around a room or even outdoors. There is possibility that a user could collide with surrounding obstacles and be injured because of walking around in real space without removing the HMD. In this paper we propose a walking support system that displays a route to the user's destination in virtual space using a Social Force Model simulating how pedestrians move in the presence of obstacles and other pedestrians, in order to allow a user to reach a real destination while in VR.
