Stereoscopic displays and head-tracking technology

This is related to my recent post, in the assemblies area, about using a hapatic (force-feedback) device to "feel" how assemblies move.  3D stereoscopic displays are fairly cheap to implement, and the technology to do head tracking is also fairly cheap, in terms of the hardware needed.  But, I have not seen a CAD set-up that took advantage of these things.

Does anyone know of a head-tracking device that works well with SolidWorks?

Has anyone seen or made use of such a system?
