PUPIL TRACKING DEVICE AND PUPIL TRACKING METHOD MEASURING PUPIL CENTER POSITION AND PROXIMITY DEPTH BETWEEN OBJECT AND PUPIL MOVING BY OPTOKINETIC REFLEX

摘要

According to an embodiment of the present invention, provided is a pupil tracking device measuring a pupil center position of an eye moving along the optokinetic reflex and the proximity depth between a pupil and an object, which comprises: a light source outputting an infrared light; a display outputting an object light; a waveguide guiding the infrared light and the object light in a direction toward the pupil; a film separating the infrared light reflected from a cornea of the eye into a plurality of lights; and the optical pick-up detecting the plurality of lights and measuring the pupil center position and the proximity depth.
