Patent ID: 7301528

Claim:
A motion controlled handheld device comprising: a first accelerometer operable to detect acceleration along a first axis; a second accelerometer operable to detect acceleration along a second axis, the second axis perpendicular to the first axis; a tilt detection component operable to detect rotation having a component around at least one of the first axis and the second axis, wherein the tilt detection component comprises: a first camera operable to generate a first video stream, the first camera aligned to focus in a first direction along a third axis, the third axis perpendicular to the first axis and perpendicular to the second axis; a second camera operable to generate a second video stream, the second camera aligned to focus in a second direction along the third axis, the second direction opposite the first direction; and a video analysis module operable to detect a direction of motion of the device based at least on the first video stream; a display operable to present a current image; a motion tracking module operable to track motion of the device in three dimensions using the first accelerometer, the second accelerometer, and the tilt detection component; and a controller operable to generate the current image and to modify the current image in response to the motion of the device.
