DETECTING A COMMAND FROM A COMBINED MOTION

For detecting a command from a combined motion, a low precision lens directs light between a high precision boundary angle and the low precision boundary angle to a camera to form a low precision image. A high precision lens directs light within the high precision boundary angle to the camera to form a high precision image. A memory stores code executable by a processor. The code combines a low precision motion of the low precision image with a high precision motion of the high precision image to form a combined motion. The code further detects a command from the combined motion.
