PUPIL TRACKING DEVICE AND PUPIL TRACKING METHOD FOR MEASURING PUPIL CENTER POSITION AND PROXIMITY DEPTH BETWEEN OBJECT AND PUPIL MOVING BY OPTOKINETIC REFLEX
PUPIL TRACKING DEVICE AND PUPIL TRACKING METHOD FOR MEASURING PUPIL CENTER POSITION AND PROXIMITY DEPTH BETWEEN OBJECT AND PUPIL MOVING BY OPTOKINETIC REFLEX
Provided is a pupil tracking device, which measures a pupil center position of an eye moving according to an optokinetic reflex, and a proximity depth between a pupil and an object, the pupil tracking device including a light source configured to output infrared light, a display configured to output object light, a waveguide configured to guide the infrared light and the object light towards a direction to the pupil, a film configured to separate the infrared reflected by a cornea of the eye into a plurality of light beams, and an optical pickup configured to detect the plurality of light beams and measure the pupil center position and the proximity depth.
