The present invention discloses a touch control system for a computer system with high compatibility. The touch control system includes an touch sensing device for detecting a touch event to generate a plurality of sensed signals conformed to a first format, and an embedded controller coupled to the touch sensing device for determining a user instruction according to the plurality of sensed signals and generating a plurality of control signals conformed to a second format to the computer system. An internal driving program in the computer system can only identify signals conformed to the second format.
