Abstract
A method of tracking a position of an eye is provided. The method of tracking a position of an eye includes converting an obtained image into a binary number image, classifying the corner of the eye, maximum and minimum values of a pupil of the eye, and extracting a feature point from the binary number image on which the binarization step is completed, calculating a distance and inclination between the corner and the pupil of the eye using the feature point extracted through the feature point extraction step, and determining a gaze direction of the eye based on the distance and inclination calculated through the distance and inclination calculation step.
