A computing device is provided comprising a keypad having a plurality of key structures, and a sensor mechanism. The sensor mechanism is positioned with respect to the keypad to provide a sensor detection region that overlays at least a portion of the keypad. The sensor mechanism is configured to detect an object in the sensor detection region and provide an output indicating the detected. The computing device further includes one or more processors that are programmed, instructed or otherwise configured to (i) receive an input signal that corresponds to the output of the sensor mechanism; and (ii) perform an operation in response to the input signal.
