Want to scroll up? Look up. Want to scroll down? Look down. PredictGaze is a control interface system developed by Aakash Jain, Abhilekh Agarwal, and Saurav Kumar. Working from a garage in Santa Clara, California, they've developed a system that could change the way people interact with digital devices:
Reading a book on your iPad and want to turn the page? Just look down at the bottom right-hand corner. Watching a smart TV and want to see what’s on the other channel? Direct your gaze at a corner of the screen. Reading a long article on your iPhone? The story will scroll down as your eye moves down the page. You can even play “Pong” using only your eyes to zip your paddle back and forward.
None of this requires any special equipment, and it works in changing light conditions, from a distance of 12 feet, and on shaky handheld devices that are constantly on the move.
