Patent ID: 8050886

Claim:
An electronic input device, comprising: one or more motion sensors operable to generate one or more signals indicative of a measured acceleration of the input device moving in a plane of motion that is tilted relative to a horizontal plane; a processing element coupled to the one or more motion sensors and operable to: receive the one or more signals; based at least in part on the one or more signals, calculate one or more corrected motion values that are indicative of an actual motion of the input device and that compensate for one or more effects of movement in the plane of motion that is tilted relative to the horizontal plane; and determine if an angle of tilt of the plane of motion with respect to the horizontal plane is not outside of a range; and an external interface operable to send one or more signals indicative of the corrected motion values to a receiving device if the angle of tilt of the plane of motion with respect to the horizontal plane is not outside of a range.
