Abstract
An apparatus includes an inertia sensing system, an optical motion sensing system, and a processing system. The inertia sensing system generates inertial data indicative of movement in relation to an inertial reference frame. The optical motion sensing system generates optical data from received light. The processing system determines movement measures from the inertial data. The processing system also select one of an in-motion output state and a motionless output state based on the optical data. During the in-motion output state, the processing system produces an output corresponding to the movement measures. During the motionless output state, the processing system produces an output indicative of zero motion regardless of the inertial data.
