Embodiment Construction

[0033] Please refer to image 3 , image 3 It is a block diagram of a computer system 30 according to an embodiment. like image 3 As shown, the computer system 30 is mainly composed of a touch sensing device 300 , a touch sensing control chip 302 and a host 304 , wherein the touch sensing device 300 and the touch sensing control chip 302 constitute a touch control system.

[0034] The touch sensing device 300 can sense an object to be tested (such as a finger, a pen, etc.) and generate one or more touch signals representing the position of the object to be tested on a detection panel (not shown). The touch sensing control chip 302 includes a detection unit 306 and a determination unit 308 . The detection unit 306 is used to compare the signal values ​​of the one or more detection signals with one or more threshold values ​​to determine whether a touch event TE occurs. In addition, if a touch event occurs, the detection unit 306 will continue to perform the above compariso...

Abstract

The invention discloses a click gesture judging method. The click gesture judging method is used in a touch induction control chip, and comprises the following steps of: comparing signal values of one to more detecting signals with one to more critical values to judge whether a touch event happens; continuing the comparison to detect duration of the touch event if the touch event happens; comparing the duration with first special time; and determining that a click gesture happens when the duration is larger than the first special time.

Description

technical field [0001] The invention relates to a method for judging a click gesture, in particular to a method for judging a click gesture simply and flexibly, a touch sensing control chip, a touch control system and a computer system using the touch sensing control chip. Background technique [0002] Generally speaking, touch sensing devices such as capacitive, resistive and other types of touch sensing devices can generate a detection related to the touch event on a touch sensing chip when the user performs a touch event. signal, the touch sensor chip compares the signal value of the detected signal with the critical value, and determines the touch point according to the comparison result, and then determines the gesture. Taking the capacitive touch sensing device as an example, the capacitive touch technology mainly judges the touch event by detecting the change of the sensing capacitance generated when the human body touches the touch point on the touch panel. The diff...
