As of now, a single side swipe across the high-tech spec’s touchpad unlocks the device, but if the patent is any indicator, that may soon get even easier.
In the patent filing, Google details how a moving object could appear on Glass’ projected screen, sort of like a screensaver, and unlock a wearable device when eyes align with the movement. In this case, we’re assuming the “wearable device” the company refers to is its own Google Glass, but it notes wearable computers can be worn “under or on top of clothing or integrated into eye glasses.”
In an attached picture, the company uses an image of a bird flying back and forth (see below). When one’s eyes follow the bird’s movement, the technology recognizes the alignment and unlocks the device.
The same concept applies to text scrolling across the screen.
“The computing system may determine that a path associated with the eye movement of the user substantially matches a path associated with the moving object on the display and switch to be in an unlocked mode of operation including unlocking the screen,” Google said in the filing.
The speed of the moving object on the screen could also accelerate or decelerate, and the technology would detect the eye’s corresponding response to those changes and in turn unlock the screen, the filing said.
