Method for detecting overlapped function area on a touchpad
First Claim
Patent Images
1. 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.
