Gesture detecting method capable of filtering panel mistouch

A gesture detecting method capable of filtering panel mistouch, comprising:

• detecting an area of a touch region of a touch event on a touch panel;
• determining whether the area of the touch region is greater than a minimum predetermined area value and smaller than a maximum predetermined area value;
• determining whether a shape of the touch region is a mistouch shape when a determination result is affirmative;
• when the shape of the touch region is determined to be the mistouch shape, a set of touch coordinates corresponding to the touch event being not reported;
• determining whether the area of the touch region is greater than the maximum predetermined area value, and reporting the set of touch coordinates corresponding to the touch event when a determination result is affirmative;
• and
• determining whether the area of the touch region is smaller than the minimum predetermined area value, and not reporting the set of touch coordinates corresponding to the touch event when a determination result is affirmative.
