PARIS – It is now possible to draw and write using just eye movements, claimed France's National Center for Scientific Research (CNRS).
French CNRS researcher Jean Lorenceau said that subjects suffering from limb paralysis can use their eyes to personalize their writing and express themselves. They can write numbers, letters, figures, their signatures and to draw through a technique based on an oculometer and a computer screen. An oculometer enables eye movements to be recorded by analyzing images of the human eye captured by a camera to calculate the direction in which the subject is looking.
