"OK Glass:" Take a picture
You can either tap the camera button just above your ear on the Glass headset, which takes an instant snap of whatever is in front of you.
Or alternatively, you can scroll through the menu like any other "glassware" app.
In this example, a photo is taken and a "vignette" is created. A vignette allows users to take a photo while embedding a screenshot of what's on the display. The image can then be sent to phone and email contacts, or shared with social networks.
