1. An electronic apparatus, comprising:
an input interface, comprising:
a central touch sensing region having a central touch pad disposed therein, wherein the central touch pad is a capacitive touch pad; anda peripheral touch sensing region surrounding the central touch sensing region and having a plurality of peripheral touch pads disposed therein, wherein the plurality of peripheral touch pads are arranged in a radial array and separated from the central touch pad by a distance, wherein the peripheral touch pads are all capacitive touch pads; a controller, electrically coupled to the central touch pad in the central touch sensing region and each peripheral touch pad in the peripheral touch sensing region, for detecting an touch on the central touch pad and generating a central sensing signal according to the touch on the central touch pad, and for detecting the touch on at least one of the plurality of peripheral touch pads and generating at least one peripheral sensing signal according to the touch on the at least one of the plurality of peripheral touch pads; and a processor, electrically coupled to the controller, for receiving the central sensing signal and the at least one peripheral sensing signal, wherein when the processor receives the central sensing signal and the at least one peripheral sensing signal, the processor executes a corresponding function according to the signal strength of the received central sensing signal and the signal strength of the received peripheral sensing signal; wherein when the processor determines that the signal strength of the received central sensing signal is decreased and the signal strength of the received peripheral sensing signal is increased, the processor executes the corresponding function. |
