Several authors have identified benefits from allowingusers to move through a virtual environment (VE) bywalking in the real world. However implementation ofthis approach can be problematic, particularly for largescaleVEs, primarily because of the need to avoid theuser colliding with real-world obstacles. 'Redirectedwalking'[1] offers a possible solution to this problem -this algorithm directs the user's movements in the realworld by imperceptibly rotating their orientation in thevirtual world. This paper extends the original redirectedwalking algorithm to increase its applicability to a widerrange of VEs. Results are presented from simulations ofthese algorithms which provide guidance fordevelopment of an immersive virtual reality systembased on redirected walking.
