APPARATUS AND METHOD FOR SENSING ROTATION

Title:

APPARATUS AND METHOD FOR SENSING ROTATION

Document Type and Number:

Japanese Patent JP2003316509

Kind Code:

A

Abstract:

To provide a means for sensing the rotation of an apparatus such as an optical pointing device.

An apparatus (300) for sensing rotation is provided with a plurality of motion sensors (16) constructed in a substantially coplanar arrangement. The plurality of motion sensors are respectively configured to generate incremental movement data indicative of movement of the sensor in two- dimensions. A rotation data generator (302) generates rotation data based on the incremental movement data. The rotation data represents the rotation of a first one of the motion sensors about a second one of the motion sensors.
