I took a look at this site.  It doesn't explain much about what
their processor does, but I can guess.  Some months ago I
saw a demonstration of a similar concept based on a PC
with a video capture card and some software.  I don't re-
member the company name and maybe it wouldn't be a
good idea to publish it anyway.  What that system did was
very simple and unimpressive:  Alternate frames were off-
set to make them appear behind the surface of the screen.
One frame was then delayed slightly to create a temporal
disparity.  Finally, some simple motion analysis determined
the major direction of motion and controlled which eye's
view was delayed accordingly.  (So it is, partially, a 
"pulfrich scam")

In other words, like most of the "fake" stereo systems, it
relied mostly on the fact that if you remove the reality of
seeing a flat screen the mind will "make up" a fairly con-
vincing perception of depth.  But it falls apart very easily,
and it's very annoying when it does, inducing headaches
and nausea in many people.

The really alarming aspect of the system I saw was that 
the manufacturer had (supposedly) won approval from the
FDA to use this system in arthroscopic surgical systems
to provide a "3D" view for the surgeon from a monocular 
camera.

You know, stereo imaging has enough problems gaining
acceptance without this sort of @#$% polluting the
public's mind.
