A motion controlled handheld device includes a first accelerometer
operable to detect acceleration along a first axis and a second
accelerometer operable to detect acceleration along a second axis. The
second axis is perpendicular to the first axis. The device includes a
tilt detection component operable to detect rotation having a component
around at least one of the first axis and the second axis and a display
operable to present a current image. The device includes 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. The device also includes a controller
operable to generate the current image and to modify the current image in
response to the motion of the device.
