Google Glass: Google reveals what users of wearable computer 'Project Glass' will see

The glasses allow wearers to see sat-nav directions, take pictures and reply to emails, but until today Google has refused to show how they actually work.

But now the firm explained for the first time what looking through its high-tech glasses feels like, the Daily Mail reports.

“Want to see how Glass actually feels? It"s surprisingly simple. "Say "take a picture" to take a picture. Record what you see, hands free. Even share what you see, live,” Google said.

“Directions are right in front of you. Speak to send a message, or translate your voice.

Get the notifications that matter most. Ask whatever"s on your mind and get answers without having to ask,” the firm added.

The firm also said all of the footage was captured through Project Glass, which will come in five colours - black, gray, blue, red or white and have removable shades.

According to the paper, Google also detailed how the first people to get hold of them.

Potential "Explorer" early-adopters will have to apply in 50 words or less, including a short video (15 seconds max) and five photographs, to explain what they would do with the early version of Glass, the paper said.
