Google Patent For Eye-Tracking Based Unlock - Roll Your Eyes To Gain Access!

With this new patent of Google, your eyes will have to do the work to get your device unlocked. Locked screens will soon display floating objects. When the user has to access the device, he has to follow the object on the screen with his eyes. The eye tracking system within the device will detect the eye movement and unlock it. The object moves up - Look up, it moves down- look down, moving left - look left, Sounds hypnotic! The patent is only on wearable technology, so expectedly we might see it in Google Glasses.

The glasses would get locked by inactivity of the wearer. A processor attached with the device will generate an object on the display. The path of the moving object would be randomly generated by the processor and may be different every time. As soon as the eye tracker identifies  that the user's pupil is following the object on the screen, it will check if the path followed by the object and the pupil matches. To ensure that the eye movement is to unlock screen, processor might variate the speed of object or shrink it's size. If the eye movement matches the path followed by the object, device will be unlocked.

Though the idea is really good and glasses with eye tracking unlock sound amazing, but who wouldn't prefer a touch button for this? Share your views.
