摘要：
A touch sensor assembly having a selectable sensitivity level allows for a user to activate a touch sensor while wearing hand covers. The touch sensor assembly includes a touch sensor, a comparison unit, and a control unit. The touch sensor has a selectable sensitivity level, and detects a value corresponding to a capacitance of the touch sensor. The comparison unit has a predetermined threshold stored therein, and determines activation of the touch sensor if the detected value exceeds the predetermined value. The control unit is operable to select a sensitivity level of the touch sensor by varying the predetermined threshold by an amount unrelated to an environmental effect on the touch sensor.
