TOUCH CONTROL DEVICE AND OPERATING METHOD THEREOF
First Claim
1. A touch control device comprising:
- a touchpad;
a first driving circuit coupled to the touchpad, configured to drive the touchpad to detect a sensed value frame of a touch event on the touchpad; and
a system circuit coupled to the first driving circuit, configured to analyze the sensed value frame provided by the first driving circuit to recognize a first finger position, a second finger position and a third finger position, and to define the first finger position as a left key position of a virtual mouse, the second finger position as a right key position of the virtual mouse according to a position relationship among the first finger position, the second finger position and the third finger position.

Abstract
A touch control device including a touchpad, a first driving circuit and a system circuit is provided. The first driving circuit is coupled to the touchpad for driving the touchpad to detect a sensed value frame of a touch event on the touchpad. The system circuit is coupled to the first driving circuit for analyzing the sensed value frame provided by the first driving circuit to recognize a first finger position, a second finger position and a third finger position, and defining the first finger position as a left key position of a virtual mouse, the second finger position as a right key position of the virtual mouse according to a position relationship among the first finger position, the second finger position and the third finger position. An operating method of a touch control device is also provided.
