Abstract

We are currently developing an immersive virtual environment display for research into the rehabilitation of balance disorders, called the Balance NAVE (BNAVE). Using this system, the therapist can create varying degrees of sensory conflict and congruence in persons with balance disorders. With the capability of changing visual scenes based on the needs of the therapist, the BNAVE is a promising tool for rehabilitation. The system uses four PC's, three stereoscopic projectors, and three rear-projected screens, which surround the patient's entire horizontal field of view. The BNAVE can accommodate many types of sensors and actuators for a wide range of experiments.
