Abstract
An eye tracking apparatus includes: a light source module including a light source and a scanning mirror, the light source being configured to provide light toward an eye region of a user while a direction of the light is changed at intervals of a predetermined time period under control of the scanning mirror; and a dynamic vision sensor (DVS) camera module configured to generate an image based on a variation in an amount of light reflected from the eye region of the user.
