Google has confirmed it is working on augmented reality glasses and has demonstrated a prototype to get feedback before putting the concept into production.
The prototype features a pair of slimline spectacles incorporating a small screen in one corner to transmit information to the wearer.
Google published a short demo video in which the futuristic specs are used to take photos, view weather forecasts, get directions and make a video call using voice-activated icons in the display.
The services available through the glasses appear to be triggered by an action taken by the user or the situation they are in. For example, one use is warned there is a 10% chance it will rain when he looks out of a window.
"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.
Google's Android operating system (OS) software is believed to power the gadget, enabling similar features to its smartphone and tablets, according to the Telegraph.
In addition to the display screen, microphone and speakers, a 3G or 4G data connection, motion sensors and GPS navigation are believed to be included in the device's capabilities.
The augmented reality specs are due to go on sale only later this year, but Google will be testing them in public in the next few months.
According to the New York Times, the Google Android glasses could cost $250 to $500 (£160-£320). Google has not announced a release date, but according to the BBC, experts say the technology shown in the video may still be some way off being ready for market.
