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,wherein as the left key position and the right key position having been detected to move forward or backward simultaneously, the system circuit triggers a rolling of a mouse wheel of the virtual mouse.

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.
