USING BIOMEDICAL SIGNAL TO DETECT NATURAL EYE MOVEMENT AND TO CONTROL ARTIFICIAL OCULAR IMPLANT

摘要

This paper reports the sensing and control of a robotic prosthetic eye that moves horizontally in synchronization with the movement of the natural eye. The prototype uses the human brain EOG (electro-ocular-graph) signal picked up by electrodes placed on the sides of a person's head to carry out the eye movement detection and control tasks. Theoretical issues on signal processing techniques are studied and simulation results are obtained. In addition, practical control system design and implementation using micro controllers are studied and implemented to carry out the natural eye movement detection and artificial robotic eye control tasks. Simulation and experimental studies are performed and the results are included to demonstrate the effectiveness of the research.
