Patent ID: 8522596

Claim:
A method of processing signals from a gyroscopic-based input device, comprising the steps of: providing the input device within a vehicle; providing a gyroscopic-based second device within the vehicle; sensing manual actuation of the input device while the vehicle is in motion; transmitting first signals from the input device in response to the sensing of the manual actuation; transmitting second signals from the second device in response to the motion of the vehicle; adjusting the first signals dependent upon the second signals; and calculating an orientation of the input device, the adjusting step being dependent upon the calculated orientation, the calculating step including: providing two infra-red emitters; emitting infra-red energy from the emitters into a passenger compartment of the vehicle; providing an infra-red sensor associated with the input device; and using the infra-red sensor to sense the emitted infra-red energy.
