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.
