Google has revealed details of its research into augmented reality glasses, as part of a bid to introduce wearable computing into the mainstream technology industry.
The firm released a short video demonstrating how the technology, still in development, could work.
The wearer is seen taking pictures, checking the weather, getting directions, and placing a video call, all of which are controlled using voice activated icons that appear in the user’s field of vision.
Android software is believed to power the gadget, enabling similar features to its smartphone and tablets.
A 3G or 4G data connection, motion sensors and GPS navigation are believed to be included in the device’s capabilities.
One person who had used the glasses said: “They let technology get out of your way. If I want to take a picture I don’t have to reach into my pocket and take out my phone; I just press a button at the top of the glasses and that’s it.”
The video suggests icons offering 14 different services will be offered to the user when the glasses are first put on, including information about the weather, their location and diary appointments.
It appears that several of these services are either triggered by an action taken by the user or the situation they are in.
The film shows one user being reminded he has a date that evening when he looks up at a blank wall, and then warns him that there is a 10% chance it will rain when he looks out of the window.
The product’s developers said they wanted feedback on the idea. They did not give any indication about when the device might go on sale or what it would cost.
“A group of us… started Project Glass to build this kind of technology, one that helps you explore and share your world, putting you back in the moment,” said a statement from Google X – the firm’s experimental lab.
“We’re sharing this information now because we want to start a conversation and learn from your valuable input.”
There had been lots of speculation about the project with some reports describing it as an “open secret”, but this is the first time Google has confirmed details of what it was working on.
Several other projects are under way in the Google X laboratory, said to include robots and space elevators.
The glasses will not go on sale until later this year, but Google employees will be testing them in public over the next few months.
The New York Times suggested they could cost between $250-$500 (£160-£320).
