Harder Video: Patients able to write only using eyes

Technology enables patients to write using only eyes

French researchers claim to have developed a way for people who have lost the ability to move their arms or legs to trace letters, numbers and even write their signature. 

 This is a video from the Telegraph  (July 2012) which describe an experiement where

Volunteers were given a series of half hour training sessions with a special eye-reading device that "tricks" the brain into thinking it is watching a moving object, allowing the patient enough control to trace letters.
Jean Lorenceau, of Université Pierre et Marie Curie-Paris reported in the Current Biology journal that after three to five training sessions participants were able to draw digits or isolatated letters. With further training, some were able to write words at a rate of 20-30 characters per minute, similar to cursive handwriting.
The technique relies on an illusion caused by a flickering screen filled with a random array of static discs varying in contrast.

 Listen to the video twice and take notes using the strategies discussed in class.
