Design and development of virtual reality based perceptual-motor rehabilitation scenarios.

Virtual reality technology may provide new options for conducting perceptual-motor assessment within simulated 3D environments for persons with a wide range of disabilities. This paper outlines our work developing a series of game-like VR scenarios to assess and rehabilitate eye-hand coordination, range of motion and other relevant perceptual-motor activities. Our efforts have focused on building engaging game-based stereoscopic graphic scenarios that allow clients to participate in perceptual-motor rehabilitation by interacting with 3D stimuli within a full 360-degree space using a head mounted display or by way of a "face-forward" format using 3D projection displays. Exploratory work using multiple video sensors to detect and track 3D body motion, identify body postures and quantify motor performance is also described.
