In a short video posted at a Project Glass page at Google+ social network, 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.

“We think technology should work for you — be there when you need it and get out of your way when you don’t,” members of the project team said in a Google+ post.

“A group of us from Google X (Labs) started Project Glass to build this kind of technology; one that helps you explore and share your world.”

“We took a few design photos to show what this technology could look like and created a video to demonstrate what it might enable you to do,” Google said, stressing that the glasses were a concept far from being brought to market.

“We’re sharing this information now because we want to start a conversation and learn from your valuable input.”

The project team invited people to express ideas for the glasses at the Google+ page.

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.
