Google Glass  - how it works

•  a wearable computer with an optical head-mounted display.
•  Google Glass displays information in a smartphone-like hands-free format that can communicate with the Internet via natural language voice commands.
• Google Glass is a camera, display, touchpad, battery and microphone built into spectacle frames so that you can perch a display in your field of vision, film, take pictures, search and translate on the go.
• it is recording your first-person perspective, allowing you to take snaps or footage of what you are actually seeing.
