Abstract:

Systems and methods according to the present invention describe free space pointing devices (400) which enhance usability by transforming sensed motion data from a first frame of reference (e.g., the body of the free space pointing device (400)) 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 (400) is held by a user.
