The present disclosure generally relates to a gaze tracking device. Gaze tracking is a process of measuring either the point of regard or the motion of an eye relatively to the head of a person. A gaze tracking device is a device capable of measuring eye positions and eye movement. In order to track the gaze of a person, infra-red light is projected into the users eye. Utilizing the primary Purkinje reflection and the pupil-masked reflection, the position of the eye of the user is determined. The gaze tracking devices running such a tracking method offer a limited field of view due to the illumination scheme combined with the geometry of the reflected images. It is proposed a gaze tracking device embedding a light-field camera. Such a gaze tracking device may be embedded in a head mounted device.
