The device has a camera to capture fleeting moments and allow others to see the world through your eyes. It also has a speaker, microphones as well as a processor and sensors which can give information on what users are seeing.
Wearers of the glasses could see directions to their destination appear literally before their eyes. They can also buy things online or even talk to friends over video chat as they walk around. Who ever wears the glasses can record what they are seeing on the built-in camera and access information on what's around them.
Google introduced the device at a launch event showing live feeds from the cameras on glasses worn by sky-divers.
As the daredevils jumped out of a blimp flying above San Francisco, attendees at Google's I/O event watched the video footage from their perspective.
They also watched the live stream from cyclists jumping over ramps then riding into the conference room.
The company is selling the glasses for $1,500 - but only available to the people present in the annual three-day conference in San Francisco.
