Abstract

The present invention discloses a sliding method for touch control comprising the following steps. First, an input module is used to touch a first position and a second position on a touch display interface, and the touch display interface generates a time signal while being touched. The time signal is compared with a preset time signal to determine stopping actuation or sliding. In case of a sliding motion, first direction actuation is performed when a first direction function is larger than a second direction function, whereas second direction actuation is performed. Next, a velocity function signal is derived according to the distance and the time signal, and then compared with the first and second preset velocity functions to determine first, second or third velocity actuation.
