Have Google figured out a way to solve the accomodation/vergence problems inherent in screen based 3D displays (http://research.microsoft.com/apps/pubs/default.aspx?id=6402...)? Because if not, these things are going to suffer from the same dismal failure that every other 3D display product has over the last 30 years.
It's not clear they're going for a 3d experience. My guess is it's just a hud without eye tracking. A camera for labeling the world a'la virtual light would be cool, but still laggy. Does not matter. I would insert the picture of a kitten with the text "want" but this is not reddit.
It needs to be 3D to pitch text. Hold a piece of text 3 inches away from your eyeball and try reading it. Then imagine how painful it would be to have that there 8 hours a day.
I disagree. Every single consumer 3d tech is a fixed focal length. Neither the 3d tv, nor the movie screen changes distance. there's nothing special in the glasses to change distance, it's simply blocking out images from one eye.
I think you mean something like the image needs to appear some distance away from the eye. Yes, i agree with that. There are old solutions to that problem.
You could show each eye a different image, and get a depth effect... but that has all of the problems you pointed out.
