Abstract: A handheld computing device is introduced comprising a motion detection sensor(s) and a motion control agent. The motion detection sensor(s) detect motion of the computing device in one or more of six (6) fields of motion and generate an indication of such motion. The motion control agent, responsive to the indications of motion received from the motion sensors, generate control signals to modify one or more of the operating state and/or the displayed content of the computing device based, at least in part, on the received indications.
