Force-feedback input device

Abstract

A force-feedback input device includes: a base; an operation member supported to be movable in a first direction with respect to the base; a shape memory alloy wire whose length changes when the operation member moves toward one side in the first direction; and a controller electrically coupled to the shape memory alloy wire, and having a processor and a memory storing computer-readable instructions, which when executed by the processor, cause the controller to change a current flowing through the shape memory alloy wire to change a length of the shape memory alloy wire when the operation member, moving toward the one side, reaches a first position. The controller is further caused to supply a measurement current to the shape memory alloy wire to measure a resistance value of the shape memory alloy wire, and detect a position of the operation member based on the resistance value.
