Abstract
The present invention provides a method for detecting a touch trace starting beyond a touch area. The method comprises the following steps: receiving touch events happened in the touch area detected by a touch module; plotting a touch trace according to the touch events outputted from the touch module; determining whether a first touch trace beginning with a first point as the touch trace starting beyond the touch area; and determining whether a second touch trace beginning with a second point as the touch trace starting beyond the touch area, wherein the first point is within a first range to a boundary of the touch area and the second point is within a second range to the boundary, and the second range is larger than the first range.

An electronic device configured to detect touch traces starting beyond an associated touch area that works with said electronic device, comprising:
- a touch module for detecting touch events taking place in said touch area;
- and
- a processing module, electrically coupled to said touch module, for plotting touch traces taking place in said touch area according to said touch events outputted from said touch module,
- wherein when said touch module has been in a detecting mode more than a time period, said processing module determines whether a first touch trace, which started at a first point, started beyond said touch area,
- wherein while said touch module is in the detecting mode within said time period, said processing module determines whether a second touch trace, which started at a second point, started beyond said touch area,
- and wherein the distance between said first point and the boundary of said touch area is within a first range, the distance between said second point and the boundary of said touch area is within a second range, said second range being larger than said first range.
