Google Project Glass

No, I'd say more like 3-5 years. All this technology is around now, including facial recognition and voice analysis apps (including from this company) for Google Glass. Like you say, it's the regular-looking glasses that is the big trick. I can't imagine that's too many years off.

And Google is already working on embedding the same concept in contact lenses - even that is probably only ten years off. The glucose sensing lenses they just announced for diabetics is from the same group working on that.
