The image sensor captures reflected light generated from the object to be detected to generate a sensing result. The processor generates detection information according to the sensing result. The feedback module generates feedback according to the detection information.

Abstract: A computer readable recording media comprising at least one program code recorded thereon, a touch control method is performed when the program code is read and executed. The touch control method comprises the following steps: (a) detecting location data for an object relative to a detecting surface to generate at least one displacement data; (b) storing the displacement data to a storage apparatus and outputting the stored displacement data to a target apparatus from the storage apparatus after storing the displacement data for a predetermined time period, when the object touches the detecting surface; and (c) cleaning the stored displacement data when the object leaves the detecting surface.
