The hardware is innovative!
For those who are saying it looks unfashionable, the product you see in the video is NOT FINAL! The more sleek, consumer version of the glass will come out next year.
Google Glass does not track hands. It does not have a depth camera, so there is no way to accurately track any object at anytime (beside location!).
Oculus Rift is totally different and cannot be compared.
For those who say this technology is useless is not visionary. Blind people can use it to aid them when going about. This technology can even be used to auto-pilot vehicles and other type of carriers. The glass can highlight piano keys to teach new students how to play the piano. People can use the glass' calculation to help them learn in sports. There is so much possibilities that dismissing it as useless is absurd.
