    Exploring large virtual environments with an HMD on foot



    Virtual Environments presented through head-mounted displays (HMDs) are often explored on foot. Exploration on foot is useful since the inertial cues of physical locomotion aid spatial awareness. However, the size of the virtual environment that can be explored on foot is limited to the dimensions of the tracking space of the HMD, unless gain is scaled [Williams et al. 2006]. This work explores methods of remedying this limitation by changing the location of a user in physical space while maintaining their spatial awareness of their virtual space, a technique we call “resetting”. Resetting involves physical locomotion with optical manipulated flow in such a way that the user’s sense of where they are relative to objects in their virtual environment is not changed. We assess three plausible methods of resetting.
