Abstract: A gaze tracking device includes a first image acquisition unit installed at a right side of a face of a user to acquire a side image of a right eye, a second image acquisition unit installed at a left side of the face of the user to acquire a side image of a left eye, a fixing unit to fix the first image acquisition unit and the second image acquisition unit, and a gaze tracking unit to track a gaze position of the user by deriving a pupil and iris area, a sclera area, and an angle between eyelids from the side image of the right eye and the side image of the left eye. Accordingly, accurate gaze tracking is ensured while realizing a compact and lightweight gaze tracking device.
