Google has just released a video which shows off the UI for its Glass project—and it looks kinda neat. We've seen some similar videos before, but this one shows off far more about the device's functionality.
Jed Fisher's insight:
I'm sure everyone has seen this but just in case.
Also worth looking at the Vuzix M2000AR glasses – build for industry.
And also the work that Oakley and Value are doing.
