Google Glass Now Adding Eye Winks for Picture Taking

The new wink function could in the future also let users make purchases, obtain search results and much more, according to Google.

Google Glass just got another cool collection of new capabilities, including the ability to take a photograph with only a wink of a user's eye.

The updates, which also include the arrival of Google+ Hangouts for Glass and easy sharing of Glass-shot videos onto YouTube, were unveiled in a Dec. 17 post on the Glass+ page.

"You've shared your wishes, we've made our list and checked it twice, and now we're closing out 2013 with some of your most popular requests," the Glass team states in the post. Among the other new features are a screen lock for Glass to prevent unauthorized users from operating the devices, a new iOS app for iPhone fans and improved features for using Glass with Google Play Music All Access subscribers.

Topping the list for coolness, however, has to be the new wink feature.

"Glass is about helping you look up and experience the world around you without getting bogged down by technology," the post states. "Based on this philosophy, we've got a new setting that lets you quickly and easily capture the moments you care about with a simple wink of the eye. Whether it's capturing an amazing sunset on an evening walk, or photographing your receipt for the lunch you'll need to expense, you can now stay in the moment and wink to take a picture instantly. If you want to turn it on, just swipe over to Settings."

And while the new photo capturing capability is cool, there's still more to come for wink, according to the post. "We're starting with pictures, but just think about what else is possible. Imagine a day where you're riding in the back of a cab and you just wink at the meter to pay. You wink at a pair of shoes in a shop window and your size is shipped to your door. You wink at a cookbook recipe and the instructions appear right in front of you—hands-free, no mess, no fuss. Pretty cool, right?"

The other new features certainly don't have as much pizzazz, but they'll like also be appreciated.

The new lock screen will help Glass users protect the operation of their device by others. "We get a lot of questions from Explorers about ways to make Glass even more secure, so this month we're adding the ability to lock your screen," the post states. "Just like with your laptop or phone, no one can use your locked Glass until you enter your secret Glass handshake using taps and swipes. You can set it up in Settings."
