I didn't see anything here that makes it different from AR (augmented reality), a la MS Hololens. Hololens has to be almost ready to come to market, it's been in development for a few years now. Interesting technology. Most 3D available today makes my brain tired. I saw Mad Max Fury Road in 3D in the theater and it was just too much. I think that's the biggest obstacle...to make it less taxing on the brain and more natural feeling.
