um
it's a thing with a little screen, voice recognition, and a camera
like for real
the most advanced thing this has is a transparent monitor
It also has GPS, and (according to the video) video-to-map recognition, being able to see what you're looking at and place it on the map.
But I think it's the ease-of-use that is the real point it's trying to make.
The ability to take a photo or video by simply looking and saying.
No need to hold a camera and press buttons or anything.
That, tied in with the see-through aspect of it, making it non-invasive, means that it should become a perfectly symbiotic tool in your day-to-day life.
No need to check a watch or phone for the time, or the weather, or text messages. Instead it's relayed to you in this form of a Heads-Up-Display, in front of your eyes, yet not being intrusive.
Connect it with a blue-tooth style headset for listening and you could easily have it replace most functions of modern phones, in giving it the ability to recieve calls.
It's certainly a very cool concept, and even if it's not commercially successful, I can only see it as a good sign of where technology can go on from where we are today.
Google's taking an interesting leap forwards.
I do worry that it will end up being ridiculously expensive however, and quite possibly rather fragile.
