Interface Lets You Write with Your Eyes

Jul-29-12 A new interface that allows people to write on a screen by tracking their eye movements could offer paralyzed people another option for communication.

Developed by Jean Lorenceau, a neuroscientist at the Université Pierre et Marie Curie in Paris, the system features a glasses-camera that attaches to the person's head. The camera tracks eye movements, smoothing the tiny naturally sudden movements—called saccades—with software. As the user moves their eyes to write, the computer interprets the motion while ignoring the saccades, promoting a steadier flow.

The device does require some practice, and future refinements will help to smooth out the motions even more.
