1. A portable electronic apparatus, comprising:

  • a capacitive touch sensor unit for monitoring a touch input interface, the capacitive touch sensor unit selectively generating a first sensed coordinate;

    an acoustic touch sensor unit for monitoring the touch input interface, the acoustic touch sensor unit selectively generating a second sensed coordinate; and

    a processing unit coupled to the capacitive touch sensor unit and the acoustic touch sensor unit;

    wherein the processing unit selects or executes an application function on the touch input interface according to the first sensed coordinate when both of the capacitive touch sensor unit and the acoustic touch sensor unit sense a touch input on the touch input interface at the same time and in response generate the first sensed coordinate and the second sensed coordinate respectively.
