Look, but don't wink. A new feature of Google Glass makes it easier than ever to take a photo. (Photo via Glass's Google+ page.)

The most eye-catching new feature of Google Glass is its new "Wink" feature. With Wink, users can take a photo with Google's wearable camera with just the blink of an eye instead of audibly asking the device to capture an image.

The Wink tool is an example of Google incorporating features created by a Glass user group of developers. Mike DiGiovanni, one of the original "Glass Explorers," made the "Winky" app for Google Glass in May, prompting concern about the invasive nature of subtle photography.

Google doesn't see a world with WInk as a creeper's paradise. Instead, it is looking ahead at using Wink for shopping or instant payment, but that all starts with the photo feature.

From Google Glass's official statement:

Glass is about helping you look up and experience the world around you without getting bogged down by technology. 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.

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?

Aside from Wink, Google also shared more visual news for Glass. Users can now upload directly to Google-owned YouTube from the device by saying “OK Glass, share with YouTube.”

Other new features include a lock screen that limits access to those that know the "secret handshake" of swipes and taps, access to Google Hangouts messaging for both text and pictures and the announcement of an iOS app for Glass that should be available for download later this week.
