摘要

Immersive VEs (IVEs) have had difficulty simulating large-scale environments because they typically have a limited tracking area. This research study techniques has established that IVEs which incorporate a wearable rendering unit can simulate virtual worlds of unlimited size. The work has overcome the physical space constraints of wearable IVEs by developing and implementing Redirected Walking (RDW). RDW works by imperceptibly rotating the virtual scene around the user's viewpoint so that the user's real body is continually directed away from the boundaries of the tracking space. Experiments have been completed which examine the effects of RDW on user performance while involved in both constrained and unconstrained navigation tasks and which compare the performance of generalized Redirected Walking algorithms. Preliminary work has been completed on Fully Optimized RDW for Constrained Environments(FORCE). Results indicate that the FORCE algorithm performs better than generalized algorithms and can take advantage of all available space in concave tracking areas. Preliminary work has also show that RDW can be used enable multiple users to simultaneously share a tracking area.
