You Might Unlock Google Glasses By Simply Rolling Your Eyes

Google has earned a patent for screen unlock that uses eye-tracking information, meaning when you finally get your hands on a pair of its augmented reality specs, you could access them with an eye roll. Just don't let your mum see you do that.

Your eyes would follow a moving object, probably in some kind of pre-determined pattern, and then you'd be in. Look left. Look right. Now look up. Sounds like a trip to the optometrist's office. The patent applies to a wearable computing system, and although it doesn't explicitly say it's for Google Glasses, it's pretty obvious. This gives us another small clue as to what the frames will actually do beyond the overhyped BMX/parachuter stunt we saw twice at I/O. We'll see, just not until 2014. [USPTO via Engadget]
