Touch device and feedback method for touch

摘要

A touch controlling device includes a sensing module, a processor and a feedback generator. The sensing module senses first coordinates and second coordinates. The processor generates an touch area difference according to the first coordinates and the second coordinates. The feedback generator generates a feedback corresponding to the touch area difference. Specifically, the touch device determines the force of touch based on the touch area difference without any force sensing plate attached thereon. Consequently, the thickness of the touch device and the cost of the touch device are reduced.
