Darla Burns wrote an entire book without ever physically typing a word. Burns suffers from amyotrophic lateral sclerosis (ALS) and is completely paralyzed. She is unable to move her arms or hands to type, so she wrote a book using her eyes.
Burns used her eyes and a special computer to type by looking at one letter or a short combination of letters at a time. She uses that same computer to speak, just as Stephen Hawking (one of the most famous sufferers of ALS) does. The book was her son's idea, and it took Burns a few months to write it.
The book, a memoir, tells Burns' story of living with ALS for the past 6 years. One reviewer on Amazon calls it "a must read for anyone who wants or needs some insight and understanding of life with ALS."
