Google is rumored to be working on some HUD glasses that provide a display with a computer interface with a few buttons on its arms. It will come with a transparent LCD or AMOLED display and apparently it will slightly look like the Oakley Thump MP3 glasses shown above.
Unfortunately there are no more details on these glasses, but perhaps you can imagine them using Android to display email, text messages, social network updates, or even phone calls. It would be quite a cool phone accessory with microphones and a set of earphones like those on Oakley Thump.
Maybe these glasses also remind you of Terminator?
