ABSTRACT:
A memory wire Braille tactile system for continuously replicating a plurality of Braille characters on a single display which is substantially less costly than conventional prior art and allows the user to maintain their level of touch sensitivity. The inventive device includes a housing having an interior portion, a securing member attached near one end of the housing within the interior portion, a first plate attached to the housing opposite of the securing member, a second plate between the first plate and the securing member, a plurality of contactor shafts slidably projecting through the plates, and a plurality of memory wires connected at one end to the securing member and connected to the contactor shafts opposite thereof. A plurality of compression springs are attached to the contactors for forcing the contactors outward from the first plate. Electrical current is selectively applied to selective memory wires thereby transforming them into an austenitic state which creates the desired Braille characters.
