Touch sensor, touch panel, method for identifying unexpected touch and computer

A touch sensor, a touchpad, a method of recognizing an unintended touch event, and a computer device implementing the method, in which a control circuit of the touch sensor recognizes whether the unintended touch event is included in a touch signal running on the touchpad, whether the received touch signal is an unexpected touch event is judged according to whether the touch position judged by the touch signal falls on an object detection area defined on the touch panel, if the received touch signal is judged to be an unexpected touch event, the signal is discarded and not processed, and if the touch position falls on a touch detection area defined on the touch panel, the signal is not processed. If the touch event is not the unexpected touch event, it is indicated that the touch event is valid, and a touch signal is reported to the computer device. 一种触控传感器、触摸板、识别非预期触碰事件的方法以及实现此方法的计算机装置，其中触控传感器的控制电路根据运行在触摸板上的触碰信号识别其中是否包括非预期触碰事件，在所述方法中，根据触碰信号判断的触碰位置是否落于触摸板上定义的一对象侦测区而判断所接收的触碰信号是否是非预期触碰事件，若判断为非预期触碰事件，信号会被屏弃而不处理，
