TOUCHPAD CONTROLLING METHOD AND TOUCH DEVICE USING SUCH METHOD
First Claim
1. A touchpad controlling method for moving a position of a cursor on a display screen of an electronic appliance or executing an instruction by sensing a touching gesture on a touchpad, at least one touching point being generated in response to said touching gesture on said touchpad, said touchpad controlling method comprising steps of:
- detecting a number of touching points in response to said touching gesture on said touchpad and a position of each touching point;
operating said cursor and said instruction in a relative coordinate mode if said number of touching points is equal to 1; and
operating said instruction in an absolute coordinate mode if said number of touching points is greater than 1.

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.

9. A touch device touchpad for use with an electronic appliance, said electronic appliance comprising an operating system and a display screen, said touch device controlling a position of a cursor on said display screen or executing an instruction by receiving a touching gesture, said touch device comprising:
-
a touchpad connected to said electronic device for receiving said touching gesture, wherein at least one touching point is generated on said touchpad in response to said gesture on said touchpad, and a number of touching points in response to said touching gesture on said touchpad and a position of each touching point are detected by said touchpad, wherein said cursor and said instruction are operated in a relative coordinate mode if said number of touching points is equal to 1, and said instruction is operated in an absolute coordinate mode if said number of touching points is greater than 1; and a coordinate transformation program installed in said electronic appliance, wherein if said number of touching points is greater than 1, said coordinate transformation program is executed for transforming said position coordinate of each touching point, so that said instruction is executed on a neighboring region of said cursor shown on said display screen by said operating system. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
