Touch screen with sensory feedback

摘要

A load control device for controlling the amount of power delivered to an electrical load from an AC power source provides improved sensory feedback to a user of the load control device. The load control device comprises a touch screen actuator having a touch sensitive front surface responsive to a plurality of point actuations, each characterized by a position and a force. The touch screen actuator has an output operatively coupled to a controller for providing a control signal representative of the position of the point actuation. The load control device further comprises a visual display and an audible sound generator, both responsive to the controller. The controller is operable to cause the visual display to illuminate and the audible sound generator to generate an audible sound in response to the control signal of the touch screen actuator.
