Google Glass is a wearable computer with a head-mounted display that allows users to access the internet and run apps hands-free. It projects information in a user's field of vision using an optical head-mounted display. Google Glass responds to voice commands and gestures to allow users to take photos, search the web, and use apps while keeping their hands free. The device is designed to be lightweight and unobtrusive. While currently only available to a limited number of users, Google hopes to refine the device and make it more widely available to the general public.
