METHOD OF EYE-GAZE TRACKING AND SYSTEM ADOPTING THE METHOD

摘要

PURPOSE: A gaze tracking method and a device thereof are provided to construct an interface system based on user sensitivity by providing eye fatigue reduction method based on eye fatigue information. CONSTITUTION: A learning front coordinate for all division areas in a three-dimensional space and a learning pupil coordinate corresponding to the learning front coordinate are obtained by using a front camera and a user eye(114). A front reference coordinate corresponding to the whole areas including the division areas and a user pupil reference coordinate are obtained(118). An automatic front coordinate locating in the reference coordinate and an automatic generation coordinate around a pupil are generated by using the pupil reference coordinate and the front coordinate(119). A gaze location of a user for a three-dimensional space is determined by using the automatic generation coordinate and the reference coordinate(201).
