1. A pointing device comprising:

  • a first rotational sensor for determining rotation of said pointing device about a first axis and generating a first rotational output associated therewith;

    a second rotational sensor for determining rotation of said pointing device about a second axis and generating a second rotational output associated therewith;

    an accelerometer for determining an acceleration of said pointing device and outputting an acceleration output associated therewith; and

    a processing unit for modifying said first and second rotational outputs based on said acceleration and for generating an output based on said modified first and second rotational outputs,wherein said first rotational sensor further comprises a first resonating mass attached to a first frame, wherein said first resonating mass in said first rotational sensor resonates along said first axis, wherein displacement of said first resonating mass along said first axis is measured by said first rotational sensor using the Coriolis acceleration effect to generate said first rotational output.
