摘要
A method of controlling a cursor on a screen by using a touch device includes changing a display coordinate set of the cursor on the screen representative of an object according to a relative coordinate set with respect to movement of the object on the touch device, hiding the cursor from the screen when the object leaves the touch device for a duration in excess of a predetermined time, and when the cursor is not displayed on the screen and an object touches the touch device, computing an initial display coordinate set of the cursor on the screen according to an absolute coordinate set of the object on the touch device and a resolution ratio between the touch device and the screen. With this method, the cursor on the screen can be intuitively operated by using the touch device.
