Google Glass is a wearable computer with an optical head-mounted display (OHMD). It was developed by Google with the mission of producing a mass-market ubiquitous computer. Google Glass displays information in a smartphone-like hands-free format. Wearers communicate with the Internet via natural language voice commands. Google Glass became officially available to the general public on May 15, 2014. Before that, users were required to receive invitations before they could try Google Glass.
