Communication by Eye Closure-A Microcomputer-Based System for the Disabled

In this paper the development of hardware and software for an optical communication system based on the monitoring of deliberate eye blinks is shown for use by people with very severe disabilities. The system relies upon the use of software written for a simple home computer to interpret the eye blinks and construct messages, with the efficient use of the blink signal to access letters of the alphabet and a library of words.
