1. A touch control device, comprising:
- an input element comprising a touchpad and a control unit, the touchpad having a first area and a second area defined thereon, the control unit being connected to the touchpad and configured for detecting a position on the touchpad that is touched by an operating object, so as for the control unit to obtain first coordinates, wherein the first area is defined in a peripheral area of the touchpad and the second area is defined in a central area of the touchpad; and
a computation unit connected to the control unit, wherein if the touch by the operating object starts in the first area, the computation unit calculates, according to the first coordinates and a first set of ratios, corresponding coordinates of the operating object on a screen; and
if the touch by the operating object starts in the second area, the computation unit calculates the corresponding coordinates of the operating object on the screen according to the first coordinates and a second set of ratios, wherein the second set of ratios is different from the first set of ratios.

Abstract
A method for controlling a touch control device includes defining a first area and a second area on a touchpad, detecting whether a touched position on the touchpad that is touched by an operating object falls in the first area or the second area, and calculating the corresponding on-screen coordinates of the operating object with different sets of ratios depending on the touched position.

9. A method for controlling a touch control device including a touchpad having a first area and a second area, wherein the first area is defined in a peripheral area of the touchpad and the second area is defined in a central area of the touchpad, the method comprising steps of:
-
A.) detecting a position on the touchpad that is touched by an operating object, so as to obtain first coordinates; B.) determining whether the touch by the operating object starts in the first area or the second area; C.) calculating, according to the first coordinates and a first set of ratios, corresponding coordinates of the operating object on a screen, if the touch by the operating object starts in the first area; and D.) calculating the corresponding coordinates of the operating object on the screen according to the first coordinates and a second set of ratios, if the touch by the operating object starts in the second area, wherein the second set of ratios is different from the first set of ratios. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for controlling a touch control device, comprising steps of:
-
A.) determining the number of operating objects on a touchpad; B.) determining the number of instruction items of a currently running application program; and C.) if there are plural said operating objects on the touchpad and if there are plural said instruction items, defining a virtual frame on a screen and calculating, according to coordinates of the operating objects on the touchpad and a third set of ratios, corresponding coordinates of the operating objects in the virtual frame. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
