Google has demonstrated its Glass technology working for the first time, in a video released today.

The company, which first announced Glass almost 12 months ago, had previously only talked about what it hoped to be able to achieve with the device. As revealed in the video today, many of those features have made it into the device, as well as some new and interesting ones.

In the video (below), Google shows off the interface for the first time, as well as demonstrating how the device will be voice activated. Users of Apple’s Siri will be right at home, from what we can see.

Taking a picture is as simple as saying "Take a picture". Video calling is as simple as saying “Hang out with…”, while it is possible to use the device to dictate your thoughts. As well as searching for information, you can also pull up pictures, which are displayed in a grid of three-by-two in the video.

One of the major uses Google hinted at almost a year ago was using Glass to find your way around new places. The video reveals another neat feature for those of you wanting to take your Glass abroad: the ability to translate phrases into other languages.

Also shown in the video is Google Now integration. In the example in the video, a man is at an airport. His Glass pulls up information about his terminal, gate, and departure in the corner of the display. The video also hints at further navigation-based uses.

Along with the video, Google announced a new wave of pre-order openings for the $1,500 (£980) gadget.

The company also revealed it is giving people the chance to get hands on with the device… so long as you live in the US and are still willing to pay the $1,500 price tag for the device.
