[sldev] Anyone here with OpenCV experience?

I think we could be getting way way ahead of ourselves here.  Before judging
whether this or that library is good, what exactly is the application(s)
being discussed?  There seems to be a bunch of multiple takes on things.

The one I was personally expecting at the start of the thread was the thing
that was dicussed once before [1] -- something like Johnny Lee's Wiimote
hack [2], but without the Wiimote hack.  For such an application, it's not
obvious to me that there's a need for detection of, say, pitch, yaw, or
roll, other than maybe being robust to their presence.  (For example, if you
roll your head, both the in-world camera and your real-world head are
already rotating -- so why should the orientation of the world change with
respect to the orientation of the screen?  It's not like the screen is
moving along with your head.)  Something pretty basic would probably be
okay.

Another take seems to be like treating movements like generic gestures and
mapping them to commands or controls with less constraint.  Something like
TrackIR seems to try to exaggerate all the motions, even stuff like roll.

Yet another take includes mouth and eye movements, etc. like that Logitech
demo.  I agree that this would be very nice, but this seems like it'd need
server-side support too to be useful, and maybe it's outside the scope of
what was intended....

I think we need to settle on our expectations before figuring out which
libraries are best.
