Eye word processor (EWP) and peripheral controller for the ALS patient

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.
