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 using a combined contribution of an output for a first axis of the accelerometer and an output for a second axis of the accelerometer obtained by interpolating the output for the first axis of the accelerometer and the output for the second axis of the accelerometer; and
controlling rotation of the rotatable object based on the determined orientation,wherein the interpolation is based on the following equation;
Do=C1×
Xoutput+(1−
C1)×
Youtputwhere Do is the determined orientation, C1 is a constant, Xoutput is the output for the first axis, and Youtput is the output for the second axis.

Abstract
An example system and method controls a rotatable object on a display using a handheld control device comprising an accelerometer. The example system and method involve determining an orientation of the handheld control device using an interpolation of an output for a first axis of the accelerometer and an output for a second axis of the accelerometer. The rotation of the rotatable object is controlled based on the determined orientation.
