Augmenting reality in rehabilitation medicine.

Virtual reality comprises the computer-based generation of realistic three-dimensional visual, auditory, and tactile environments in which a user can explore and interact with virtual objects. Although traditionally used for input devices to virtual worlds, the instrumented glove and sensor technologies of virtual reality may provide a dramatic new method for the measurement and amplification of human motion. This paper discusses some potential uses of virtual reality technology to support and augment routine activities for people who have physical disabilities. We present two different but related applications of this technology.
