Abstract
A tactile stimulator array system and method of operational incorporating a plurality of tactile elements having touch-stimulating portions which are positioned through corresponding openings formed in a touch plate. The tactile elements are moved by actuator wires which are formed of a shape-memory alloy material. Electrical control signals from a programmed computer system heat individual wires through the materials phase change transition temperature so that the wires contract to their memory shapes and raise the elements. The touch-stimulating portions then extend above the touch plate where they can be sensed by the user.
