A system for cursor control by eye position

This thesis describes the design and development of a workstation intended for totally incapacitated persons. Among such people are individuals who can control only the motion of their eyes. The workstation described in this thesis uses a dedicated microcomputer system and eye-position sensors to control the cursor on the screen of a computer terminal. The cursor can be used to point out items on a menu, thereby allowing the user to communicate with the computer, hence with any system connected to the computer. The following are the salient features of the prototype system: - eye-position sensing for display control; - menu driven software;- a means for communicating with a remote host computer; - an application program allowing the user to produce "typewritten" documents using only the eyes. The system was tested and it performed satisfactorily.
