Abstract
A touch sensor, a touch pad, a method for identifying an inadvertent touch event and a computer device are provided. A control circuit of the touch sensor identifies whether there is the inadvertent touch event in response to the touch signals that indicates at least one touch event applied to the touch pad having the touch sensor. In the method, the touch signals are discarded if the inadvertent touch event is identified when a touch position corresponding to the touch signals is within an object detection area defined for the touch pad, or the touch positions in response to the touch signals are reported to the computer device if a multi-touch event is identified when the touch positions are within a touch detection area defined for the touch pad.
