Abstract:Redirected Walking (RDW) is a technique that allows exploring immersive virtual environments by real walking in a small physical room. RDW employs so-called redirection techniques (RETs) to manipulate the user's real world trajectory in such a way that he remains within the boundaries of the physical room. We present a generalized approach to planning and applying RETs using optimal control concepts. It is capable of dynamically selecting suitable RETs and also controlling parameters like their strengths to maximize the free walking experience. The proposed probabilistic planning algorithm is evaluated within a user study.
