Abstract

In a method for window movement control on a touchpad, the area size of the object sliding on the touchpad is calculated to determine the speed that the touchpad produces a movement signal to control a window such that the greater the area size is, the faster the window scrolls.

Claims

1. A method for window movement control on a touchpad having a touch-sense defined speed, the method comprising the steps of:

detecting an object sliding on the touchpad;

calculating a coordinate value of the object on the touchpad;

producing a position information according to the coordinate value;

calculating an area size of the object on the touchpad;

producing a speed information according to the area size; and

producing a movement signal according to the position information and the speed information to scroll a window.

2. The method of claim 1 wherein the coordinate value comprises an absolute coordinate value or a relative coordinate value.

3. The method of claim 1, wherein the position information comprises a sliding direction of the object on the touchpad.

4. The method of claim 1, wherein the step of producing a speed information according to the area size comprises the step of determining the speed such that the greater the area size is, the higher the speed is.
