ABSTRACT:
An input apparatus is disclosed having a hand-sensing system, a wake-up detector, and a microcontroller. After a period of inactivity, the apparatus is placed into a sleep mode to conserve power. During the sleep mode, an electrical property that the hand-sensing system presents to the wake-up circuit is measured. If the electrical property exceeds a predetermined level, then the input apparatus is activated. In alternative embodiments, an accelerometer, a pressure switch, or a computer system's response can be used to trigger the activation of the input apparatus.
