FREE SPACE POINTING DEVICES WITH TILT COMPENSATION AND IMPROVED USABILITY

摘要

Systems and methods according to the present invention describe free space pointing devices which enhance usability by transforming sensed motion data from a first frame of reference (e.g., the body of the free space pointing device) into a second frame of reference (e.g., a user's frame of reference). One exemplary embodiment of the present invention removes effects associated with a tilt orientation in which the free space pointing device is held by a user.
