Abstract:
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.
