Google has released a new YouTube video called 'How it feels [through Glass] that shows you what it'll be like to wear its Google Glass eyewear.
The video is shot in first person view, and shows a variety of people doing interesting things (skydiving, skiing, ice skating, going on roller coasters, and so on) while issuing voice commands. (See: Google Glass features)
The commands all start with "OK Glass…", which it seems is how you start an interaction with the device. So you hear people say "Ok Glass, record a video" and then see a video being recorded on screen.
Other interactions include taking photographs, starting a Google Hangout (video chat), performing Google image searches. There are also displays showing turn-by-turn directions, weather reports, and sharing images and messages.
The video has the following information from Google"
