The authors have designed an eye word processor (EWP) controlled by eye movements for victims of amyotrophic lateral sclerosis (ALS). Instead of unnatural side-to-side eye movement or blinking, the system employs the eye's natural focusing movements. It allows a patient to input eight letters per minute, call a nurse, or control certain appliances. It takes only five minutes to set up, and it has been praised by nursing staff.
