METHOD FOR OPERATION TO A MULTI-TOUCH ENVIRONMENT SCREEN BY USING A TOUCHPAD
First Claim
1. A method for operation to a multi-touch environment screen by using a touchpad, the method comprising the steps of:
- (a) defining a movable control window on the screen;
(b) when the touchpad is detected being touched, calculating an inter-window coordinate set of the detected object mapped from the touchpad to the control window according to an absolute coordinate set of the object on the touchpad and a resolution ratio between the touchpad and the control window;
(c) defining a cursor representative of the object on the screen according to the inter-window coordinate set; and
(d) according to a number and movement of the object on the touchpad, changing a coordinate set of the cursor representative of the object on the screen or the inter-window coordinate set of the cursor representative of the object in the control window.

Abstract
A method for operation to a multi-touch environment screen by using a touchpad defines a movable control window on the screen, calculates an inter-window coordinate set of the object mapped from the touchpad to the control window according to an absolute coordinate set of the object on the touchpad and a resolution ratio between the touchpad and the control window when the touchpad is detected being touched, defines a cursor on the screen representative of the object according to the inter-window coordinate set, and changes a coordinate set of the cursor on the screen representative of the object according to a number of the object on the touchpad and movement thereof. This method allows a user to intuitively operate the screen by using the touchpad.
