The User Interface Future is Here

I am, to put it plainly, blown away!

During a research routine for a text I am writing on Augmented Reality, I bumped on this awesome video on one of my favorite blogs. Not directly relevant with AR but roughly in the same neighborhood.  

I mean we've seen this before, yeah: in movies. Now, it's a tangible concept, an actual operating system which, if I may say, redefines the meaning of the term interactive. 

I know it might sound stupid, but I'm going to go ahead and say it:
Imagine the effects/benefits this form of interactivity; people will sort of, hopefully, become a bit more physically involved. So the interactivity course started from writing and went to typing, then clicking, then touching and now nodding! 

"Thank you for making science fiction real" does not even begin to describe it.
