Abstract
A touchpad controlling method and a touch device using such a method are provided. The touch device is applied to an electronic appliance. The touch device includes a touchpad and a coordinate transformation program. The touchpad is used for detecting a number of touching points in response to the touching gesture on the touchpad and the position of each touching point. If the number of touching points is equal to 1, the electronic appliance is operated in a relative coordinate mode. Whereas, if the number of touching points is greater than 1, the electronic appliance is operated in an absolute coordinate mode.
