Google Glass adds the ability to take photos by winking
Google Glass has received a major software update. Now Google Glass has the ability to take a picture by simply winking. The wink-to-capture feature is faster than having to use the camera button or the voice action. The winking feature even works when the display is off.
As part of the update, Google also added a new security feature. Other people can be blocked from using your Google Glass device unless they enter a correct pattern on the screen locks card in the MyGlass mobile app. The lock screen would be turned on anytime you deactivate Google Glass or take it off your head.
The Google Glass software update includes the ability to share videos on YouTube and send messages, share photos, and make video calls with Google Hangouts.
