Google gets patent for eye tracking-based unlock system, shifty looks get you access

Look up. Now down. Back up here again? Imagine having to do that every time you wanted to unlock your phone, as this granted Google patent for "Unlocking a screen using eye tracking information" possibly suggests. Okay, it actually looks more like it's intended for the firm's super spectacles -- which given their general hands-free nature -- makes more sense. The claims are fairly straightforward, unlocking of a device would be granted based on "determining that a path associated with the eye movement substantially matches a path of the moving object". As long as those moving objects aren't moving too fast, we think we can work with that.
