I have recently finished listening to an audible book called The Diving Bell and the Butterfly by Jean-Dominique Bauby who experienced a life changing stroke and ended up with a condition called “locked in syndrome”. This means that he remained mentally astute, but had no verbal capabilities or movement save being able to blink his left eyelid and minor head movement. The book was dictated by Bauby over a two month period by blinking his left eye and using a special alphabet template to enable him to communicate.
