Project Glass demonstration video is the stuff of dreams, in both a literal and figurative sense. Speaking with CNET, a spokesperson admitted that the augmented reality, full vision overlay seen in the project's most visible demonstration thus far isn't quite what the real thing looks like. It's being described as floating "above" the user's line of vision, about the same place where you'd normally see the edge of an umbrella or hat brim.

impractical watch-phone hybrids, single function devices like the FitBit and gigantic head-mounted displays that are useless for anything but watching movies for about 20 minutes at a time. But information leaking out of the shadowy inner test labs known as Google X indicates that the company is working on nothing less than a personal Heads-Up Display (HUD), a staple of science fiction for decades, and the goal of many converging technologies like transparent screens and microscopic transistors.
