System and method for providing a prosthetic device with non-tactile sensory feedback

Abstract

A system and method for substituting vision based cues for lost sense of touch may employ a small electronic display or other non-tactile feedback mechanism that attaches to a prosthetic arm or other limb. Devices according to certain embodiments of the present invention include an array of pressure or other sensors that may be deployed against a prosthetic hand by structures such as finger cots or gloves containing the sensors. In one embodiment, an electronic display may be used to display a colored bar that moves from left to right, and changes colors along a gradient, as detected pressure on the sensors deposed against the hand increases. Movement across space and change in color are both easily discernable visual cues for these purposes.
