Cable driven tactor
A tactor system transforms cable motion to tactor motion. A housing defining a plane is adapted for placement proximate to the skin of a user. A cable is operative to deform a tactor element in the housing, causing a portion of the element to move outwardly from the plane of the housing, thereby imparting a tactile sensation to the user's skin. For example, tension on the cable may cause a strip of flexible plastic or other suitable material to bend at a living hinge that moves outwardly from the plane of the housing. The cable may be driven by an actuator including. Two or more tactor elements may be disposed next to each other or in the same housing, with different elements being activated at different times to enhance the apparent frequency of the stimulus. For example, a reciprocating mechanism may be used to operate a pair of tactor elements out of phase with respect to one another. The cable may be controlled by a remote reciprocating mechanism, with a physical quick disconnect mechanism provided between the reciprocating mechanism and the cable.
