Abstract
An apparatus for sensing rotation includes a plurality of motion sensors constructed in a substantially coplanar arrangement. The plurality of motion sensors is each configured to generate incremental movement data indicative of movement of the sensor in two dimensions. A rotation data generator generates rotation data based on the incremental movement data. The rotation data represents rotation of a first one of the motion sensors about a second one of the motion sensors.
