摘要：
This paper presents the design and implementation of a low-cost eye tracking system that allows measuring the rotational angle of the eye and gaze direction in healthy individuals. The system consists of an EOG circuit with simple components that acquire both horizontal and vertical eye movement through regular all-purpose contact electrodes. Then the data are analyzed and translated into corresponding angle values representing the eye rotation angle in both orientations. Results show that horizontal angle measurements are much more accurate than vertical measurements. A discussion regarding the performance and possible improvements is presented.
