Abstract:
1. An apparatus comprising: a casing; a power source of limited capacity to provide electric power to the apparatus; a motion sensor to sense movement of the casing; a touch sensor disposed on the casing and providing a touch-sensitive surface enabling a touch of a tip of a digit of a user to the touch-sensitive surface to be detected; a conductive ring disposed about the periphery of the touch-sensitive surface of the touch sensor enabling an approach of the tip towards the touch-sensitive surface to be detected; a sensor interface coupled to the touch sensor to monitor the touch-sensitive surface for an indication of a touch of the touch-sensitive by the tip and to monitor the conductive ring for an indication of an approach of the tip towards the touch-sensitive surface; a processing device able to access the sensor interface and the motion sensor; and a storage accessible to the processing device and storing a sequence of instructions that when executed by the processing device, causes the processing device to:
