A couple of weeks ago, it was discovered that Google Glass has wink detection features baked into the device that could allow users to stealthily snap photographs of anything just by winking at it. Today, the first wink-to-shoot app was launched.
One of the big gripes people have with the idea of taking pictures with Google Glass camera glasses is that the device requires you to say "ok, glass, take a picture" in order to snap a shot. While this is great for situations when you need hands-free photography and don't mind saying a voice command, it would be highly inconvenient in situations in which you would rather not (or can't) talk.
It looks like Google has been one step ahead of us the whole time: it appears that the company has built "wink to snap" functionality into Google Glass' camera.
