Abstract
Stereoscopic display systems including a position-tracking system that determine the position of the stereoscopic eyewear worn by a viewer. An exemplary embodiment of the eyewear includes retro-reflective reflectors that are illuminated by an infrared illuminator proximate to or optically co-axial with a capturing camera. Suppression reflections from other reflective features in the vicinity may be achieved by control of the polarization of the infrared light.
