摘要： A method for double click detection includes the following steps. Firstly whether first event is detected is determined, if so, first corresponding position is obtained, a period counting is triggered, and first flag is set. Then whether the period ends is judged; if not and the first flag exists, a counter is incremented and second flag is set when first ending event is detected; if not and the second flag exists, second corresponding position is obtained and third flag is set when second event is detected; if not and the third flag exists, the counter is incremented when second ending event is detected; if so, a double click event is determined when the incremented value is greater than a threshold and a distance between the first and the second positions is smaller a threshold.
