Google Glass is a project started by Google that is intended to
bring hands-free display technology to the general public. By utilizing
voice commands, users can interact with their Google Glass device to get
information from their phones, participate in Google+ Hangouts or to
get information from the internet. With a wireless data connection,
Google Glass adds an augmented-reality overlay to whatever you're
looking at, automatically bringing up relevant information from various
Google sources. This is still a prototype project, but Google hopes to
bring it to consumers sometime in 2014.
