How does Google Glass work?


Google Glass brings all of the functionality of a smartphone to a lightweight pair of glasses. The concept is called augmented reality. Looking through the head-mounted display, you see your normal world, but also a small high-definition screen in the upper-right corner of your vision. While wearing Google Glass, you can use voice commands and gestures to take photos and videos of what you are seeing, launch a Google Hangout (video chat) with friends, conduct a Google search, get directions, chat using voice-totext and even translate a conversation in real-time. Google Glass won’t be released to the public until 2014, but developers have already created apps to provide hands-free recipes in the kitchen and to browse headlines from The New York Times.
