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.
What does Google Glass actually do?
Glass takes photos and videos, sends text messages, engages in FaceTime-like Google Hangouts, makes phone calls, searches Google, and gets turn-by-turn navigation with maps. It can show the weather, the time, and headlines from The New York Times that have been pushed to the device, with spoken headline summaries. For now, anyway, that's about it. Some features require tethering -- GPS-based functions that use the phone, such as turn-by-turn directions. Others, like Google Hangouts and Google Search, can also be performed over Wi-Fi. When offline, Glass only takes photos and videos.
