Conformal redirected walking for shared indoor spaces

Abstract

In this work we present a redirected walking scheme suitable for shared spaces in a virtual reality environment. We show our redirected walking to work for the case of two physical spaces (a host and a guest) being merged into a single virtual host space. The redirection is based on warping the guest space into the host space using a conformal mapping that preserves the local shape and features. We compare our technique with state-of-the art indoor redirection schemes and show its efficiency. We found our method to have better task performance, higher social presence, and less simulator sickness.
