Abstract: The disclosure relates to an eye tracking device for tracking movements of an eye comprising, a viewing plane for displaying a projection of an image to the eye of a user, an image module placed on a same side of the viewing plane as the eye, at least one illuminator for illuminating the eye, a control unit adapted to receive an image captured by the image module, and calculate a viewing angle of the eye, a holographic optical element (HOE), wherein a HOE is placed between the eye and the viewing plane, wherein the image module is adapted to capture an image of the HOE, and wherein the HOE is adapted to direct at last a first portion of incident light reflected from the eye, in a first angle towards the image module, the first angle being different from an angle of the incidence of the incident light

Abstract: The invention relates to an eye tracking device comprising one or more illuminators, each illuminator comprising a light emitting side, and each illuminator being connected to a first circuitry carder, an imaging module connected to a second circuitry carrier wherein the image module comprises optical arrangements. The plurality of illuminators, the imaging module and the circuitry carriers are embedded without gaps in a first material. The invention further relates to methods for manufacturing an eye tracking device with over-molded components.
