Abstract:
An eye tracking method in the disclosure comprises an image-capturing step of capturing a facial image including an eyeball of an object person, light from a light source that emits the light to form a corneal reflex point on the eyeball of the object person who gazes at a predetermined gaze point being reflected from the eyeball, a detecting step of calculating visual line information in a world coordinate system using the facial image captured in the image-capturing step and a correcting step of transforming the visual line information in the world coordinate system calculated in the detecting step into visual line information in a correction coordinate system that is a coordinate system different from the world coordinate system, and correcting the visual line information in the correction coordinate system using correction information for correcting a detection error caused by an individual difference of the eyeball.

Claim (Index 3):
The eye tracking device according to  claim 2 , wherein the predetermined gaze point is a point displayed on a display disposed in front of the object person, or a point in an object existing in front of the object person.
