Absolutely. Especially, since we don't have them anymore.
There used to be commercial products one could buy. No longer.

You don't need more than 640x480 to be usable. I would not have
called http://www.cc.gatech.edu/ccg/publications/starner-phd/#918
chunk, in fact, as a mirroshade it's not recognizable as a HUD.

See the Twiddler right at above URL. Yes, you can't buy one
either. You cannot also board a civil supersonic flight, or go
to the Moon.

This has nothing to do with geeks. Hands-free navigation, military,
repair technicians, multimedia, VR/AR (another technology gone the
way of the dodo) are all straightforward application profiles.

But why must mass adoption take 15 years? It makes one wonder, doesn't it.

Machine vision on video input is nothing new. Of course having cheap
3d info in realtime is neat, assuming we'll ever get to that.

Nope. It would be trivial to do with today's LCDs or OLEDs, especially
given that you can print OLEDs on curved surfaces and you can do
nonlinear mirror optics, but nope.

Try something like http://www.swopper.com/ (there are cheap clones around,
some using inflatable rubber tires as base). Do not spend more than 1 h
on it initially, slowly upping up the time.

Another option might be using a video projector, and a reclining chair.
