Could staring and moving your eyes soon be a way to unlock your favorite Google device? A new patent granted to Google makes use of eye-tracking information to unlock a screen, which brings up an interesting question, why? Before you think that Google has lost it’s mind, the likely scenario is that this patent is actually going to be applied towards Google’s computerized glasses, not their smartphones and tablets. With that in mind, this patent could make a great deal of sense, since it would be the easiest way to unlock such a device, instead of having to reach up and slide your finger across your glasses lense. When you really stop to think about it though, it seems a little odd that you can patent the way that eyes move around, which is essentially what this is. You have to wonder, what basic body movement and/or function will some company patent next?[ source ]
