Every time Glass wakes up, you’re treated to the Home screen. The Home screen is your access point to Glass features, including voice actions and your timeline.
If your display is off, tap the touchpad. The display will turn on and you’ll be greeted with the current time and the words "ok glass." Say these magic words aloud and you’ll see a menu of Glass voice actions.
If you don't feel like announcing "ok glass" to a silent room, we've got you covered. Activate Glass by tapping your touchpad. Tap again and you can swipe through all available actions.
