New technology allows paralyzed ALS sufferers to draw with their eyes:
When Los Angeles graffiti artist Tony Quan, otherwise known as Tempt1, was diagnosed with amyotrophic lateral sclerosis (ALS), he lost all muscle function in his body – except in his eyes. His brain was fully functioning, but he could not speak nor move a limb. His ideas were as abundant as ever, but he was an artist without any form of expression.
And then came The Eyewriter, a combination eye-tracking and drawing software that enabled Tempt1 to draw with his eyes. From a small hospital bed, Tempt1 drew the images in his mind while artists and hackers from the Free Art & Technology Lab drove around, downloading the images from the trunks of their cars and projecting them onto buildings for all of downtown L.A. to see.
