ABSTRACT:
A tracking device for use in an optical tracking system is disclosed. The tracking device has a plurality of faces, each face having at least three markers which can be tracked by the optical tracking system. The markers may be infrared emitting diodes. The tracking system can individually activate the markers on each of the faces and select the markers which can be most accurately tracked by the tracking system. Portions of the faces are adjacent to one another to form clusters of emitters. The clusters of emitters are separated by at least a predetermined distance corresponding to the tolerance of the optical tracking system. The field of view of the tracking device approximates a section of a sphere centered at the device.
