Abstract

A method for recognizing gestures by detecting the sensing area of a touch-control pad comprises the following steps: judging whether a touch target touches the touch-control pad or not and sending the position information to a host through a touch-control sensing module. The method is characterized in that the internal output of the touch-control sensing module comprises position signals (X,Y), input number sensing amount N and sensing area S; whether the touch target touches the touch-control pad or not is judged through the following steps: detecting the input number sensing amount N by the touch target touching the touch-control; continuously detecting the change of the sensing area S at a time when the input number sensing amount N jumps from 0 to 1; determining that the touch targettouches the touch-control pad when a trend that the induction area is increased is detected at the time, and sending a touch-confirmed signal; continuously detecting the change of the sensing area S at a time when the input number sensing amount N jumps from 1 to 0; and determining that the touch target leaves the touch-control pad if the trend that the sensing area is decreased at the time.
