Seth Weintraub of 9to5Google reports that Google is working on smart eyeglasses with a built-in heads up display that knows where you are and shows relevant Google info:
The heads up display (HUD) is only for one eye and on the side. It is not transparent nor does it have dual 3D configurations, as previously speculated.
One really cool bit: The navigation system currently used is a head tilting-to scroll and click. We are told it is very quick to learn and once the user is adept at navigation, it becomes second nature and almost indistinguishable to outside users.
Google isn’t the only company working on this idea–for instance when I visited NTT Docomo in Tokyo last fall, I tried out a similar prototype which that company had designed in collaboration with Olympus. But I wonder who’ll be the first to ship something that actually works and is useful?
