Google Glass is Always Listening, Assuming You Have a Hack

The rumored "wink" feature also discovered.

Privacy concerns are a big deal in this always-connected tech age. Beyond the constant litany of reports that social networks are sharing your information with advertisers, in walks Google Glass: a very real device capable of recording the actions of others without consent.
Granted, the headset requires the--relatively minor--roadblock of launching video and image capture from the home screen. But according to Android Police (via The Verge), the ability to use the "OK Glass" command everywhere is hidden within the software.

Github user Zhouwei Zhang has apparently discovered a number of hidden features within the Google Glass build.prop file. Sure, the ability to take pictures or video at any moment is useful. But Zhang and the Android Police team shave also discovered a previously mentioned "Wink" feature, allowing you to capture an image with the simple blink of the right eye.
Other hidden features include a very rough video stabilization option. But an important takeaway is all of these features require you to root Google Glass. And honestly, if you've paid $1500 to grab an Explorer edition of the headset, the idea of tinkering in the device's firmware is -- well, it's not a foolproof concept.
Of course, the idea of an "always-on" Google Glass doesn't alter privacy concerns in regards to the device's ability to grab images, for the most part; without the hack, wearers can pretty much take a picture without others knowing. But the question is who else is listening on the other end?
Most recently, it was revealed the Kinect launching with the Xbox One will consistently "listen" for user commands. Or, you know, listen to your mopey phone call with an ex at 3 in the morning. Microsoft claims the device will wait for the "Xbox" command before registering your speech.
