ABSTRACT:
A battery powered electronic system (50, FIG. 1) is controlled by a movement sensor (20) which senses the acceleration of the electronic system (50). The output of the movement sensor (20) is filtered by an event duration filter (FIG. 2, 120, 121) which determines if the output is of sufficient duration and acceleration to trigger a change in the operation of the electronic system (50). If the acceleration meets the triggering criteria, the electronic system (50) can be made to change an on/off state, an operating mode, or to effect an incremental change in the electronic system (50) such as adjusting the volume or channel setting. Additional movement sensors (20) oriented in different axes can be used to trigger a change in the operation of the electronic system (50) according to a plurality of different directions of acceleration.
