It’s easier than ever to take a photograph with Google Glass. Just wink. That is, if you have a pair of Google Glasses and you can wink with your right eye. I don’t and I can’t.

But, the feature is definitely cool and according to the company’s blog post on the topic, the wink feature could eventually be used for more than snapping images. You could wink a taxi meter to pay the fare, for example, or wink at a pair of shoes in a shop window to make that purchase.

Or, “You wink at a cookbook recipe and the instructions appear right in front of you — hands-free, no mess, no fuss.”

Don’t accidentally get grapefruit pulp stuck in your eye, though, you might be winking uncontrollably without knowing it and snapping photographs left and right of God knows what.
