Abstract
A special orientation sensor within a hand-held electronic computing device provides for movement of a screen cursor in response to changes in the spatial orientation of computing device. The sensor provides at least two output signals that are sensitive to gravitational force in at least two different directions, and those signals assist in determining the spatial orientation of the computing device and in determining the position of cursor 120. In one illustrative embodiment the force-sensing mechanism comprises a pair of accelerometers that provide a signal corresponding to the gravitational force applied to the accelerometers. A processor responsive to the signals of the accelerometer converts those signals to cursor position signals.
