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. Matt Clark is a freelance writer covering the world of videogames, tech, and popular culture.
