Accurate interaction with computer by eye movement tracking

The paper presents a state of the art interface system between human and computer by tracking the eye movements on the screen. The user eye EOG (electrophysiological) signal is detected, amplified and adjusted real time to give precise position of the cursor on the screen to control the computer. To better capture the EOG signal, we built a prototype electrode´s fixation device to attach on the user´s head. A software application for the digitalization and processing of the signal has also been designed and implemented. Key issues of stabilizing the signal and remove noise signal to provide reliable cursor control have been solved. The results show that the eye movement tracking for human computer interaction is feasible and can be achieved.
