For long, researchers have sought to find ways to track eye movements and use that as signals to control different devices. Until now, this was impossible because eye movements make a lot of involuntary as well as voluntary movements. And it’s quite hard to distinguish between the two. However, now Dr Jean Lorenceau at Universite Pierre et Marie Curie-Paris has been able to overcome this critical problem. He has been able to devise a medical device which can accurately read voluntary eye movements and then translate them into words.
