1. A method of controlling a rotatable object on a display using a handheld control device comprising an accelerometer, the method comprising:

  • determining an orientation of the handheld control device by weighting an output for a first axis of the accelerometer and by weighting an output for a second axis of the accelerometer and interpolating the weighted outputs to avoid discontinuity when processing data output from the first axis and the second axis; and

    controlling rotation of the rotatable object based on the determined orientation.
