Eye Gaze for Computer Control

This paper reports the results of experiments that were conducted with five subjects to determine the reliability of the use of Electro-ocular gram (EOG) for controlling computers. Experiments included vertical and horizontal eye motion. Consideration was given to identify a relationship between the angle of the gaze and signal that could be applied to cover all test subjects and generate the required spatial control signals. The results obtained are encouraging. An assessment of the data has concluded that the EOG can be successfully utilised for spatial control applications. The study recommends the choice of bandwidth for the recording, inter and intra subject reliability and difference between the vertical and horizontal movement control.
