Abstract During the last few years microprocessor based technology has transformed the design and development of assistive devices for disabled people. The benefits are considerable with far reaching implications on communication, education, recreation, employment and environmental control aspects of individual’s lives. Before these benefits can be realised, however, suitable input devices have to be devised - keyboards adapted or expanded, mechanical switches designed to be controlled by almost any co-ordinated movement of the body, etc. For the non-vocal, severely physically impaired, eye movement is often the only function which is well controlled and the following is a brief description of a simple system which allows this movement to be harnessed.
