Abstract
In a method for detecting overlapped function area on a touchpad with the overlapped function area overlapped by more than two different function areas, when the overlapped function area is touched by an object, a further function can be correctly performed according to touched duration, touched movement, or a terminal touched area pressed onto the touchpad.
Claims1
A method for detecting overlapped function area on a touchpad that has at least a main function area, a first function area, a second function area, and an overlapped area which defines a physical area where the first and second function areas overlap, the method comprising the steps of:
- determining whether the overlapped area is touched;
- and counting a touched duration on the overlapped area if the overlapped area is touched;
- wherein, if the touched duration is longer than a reference duration, a first function corresponding to the first function area is performed;
- otherwise a second function corresponding to the second function area is performed;
- wherein said second function is distinct from said first function;
- whereby the main function area is defined by an area not including the first, second and overlapped function areas.
