Google Glass in action (video)

Despite many dozens and hundreds of articles and news about Google Glass, not many people who did not wear these "glasses" understand how everything works. Yes, there are several videos on YouTube, where the work of the glasses is shown, but good videos - at least. I came across a video, the author of which tried to convey the principle of the glasses as realistic as possible. And it seems like he did it.

The video is shown as if you yourself are wearing this mini-computer, controlling it in various ways. For complete realism of what is happening, the authors put on glasses on the camera, and filmed everything that happens. Points controlled voice, launching the function of receiving photo / video, plus a call on Google+ Hangout.

Among other things, the authors of the video launched a voice search to check the exchange rate, to check prices, translate text and so on. In general, the video really turned out high quality.
