What Does Google Glass Do?
If your Glass is on but not connected to the Internet, you can only take photos and videos with the device. Here’s what Google Glass does when it’s on and connected to the Internet:
Takes photos and videos, and sends them to one or more of your contacts. The Glass camera sees the world through your eyes at the very moment you take the photo or record the video.
Sends e-mail and text messages to your contacts, and receives the same from them.
Allows you to chat live via video with one or more Google+ friends via Google Hangouts.
Sends and receives phone calls.
Searches the web with the Google search engine (of course) so that you can find information easily.
Translates text from one language to another. Glass speaks the translated text and also shows a phonetic spelling of the translated word(s) on its screen.
Provides turn-by-turn navigation with maps as you drive, ride, or walk to your destination.
Shows current information that’s important to you, including the time, the weather, and your appointments for the day.
Recognizes the song that’s playing on the device and identifies the artist(s) singing the song, in case you don’t know.
If you have a Wi-Fi connection, functionality is expanded to sending and receiving e-mail messages, connecting to the Internet, sharing information on social networking websites, and participating in Google Hangouts for videoconferencing. You need to connect Glass to your phone if you want to use your phone’s 3G or 4G Internet connection, send SMS messages, and use GPS (Global Positioning System) so Glass can find your current location.
