P-27: Maintaining Position and Display Perspective in a Walking Simulator while Self-Pacing on a Treadmill

We developed a feedback controller for a walking simulator composed of a treadmill and a rear projection screen. The controller keeps the subject centered and visual extent consistent across subjects and throughout individual trials while allowing subjects to set their own walking pace.
