Playing Pong Using Just Your Eyes

“Millions of people suffering from Multiple Scleorosis, Parkinson’s, muscular dystrophy, spinal cord injuries or amputees could soon interact with their computers and surroundings using just their eyes thanks to a new device that costs just $53. Comprised of off-the-shelf materials, the new device, can work out exactly where a person is looking by tracking their eye movements, allowing them to control a cursor on a screen just like a normal computer mouse. The researchers demonstrated the device by getting students to play the computer game Pong using just their eyes.” — InstituteofPhysics
