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.
Claims17
An eye tracking device comprising:
- one or more illuminators, each illuminator comprising a light emitting side, and each illuminator being connected to a common circuitry carrier,
- an imaging module connected to the circuitry carrier, the imaging module comprising optical arrangements,
- wherein the plurality of illuminators, the imaging module and the circuitry carrier are embedded without gaps in a first material,
- wherein the first material is non-transparent to the illuminator light and wherein the first material comprises at least one opening filled with a second material, wherein the second material is transparent to IR light but non-transparent to visible light.
A method for manufacturing an eye tracking device, comprising the steps of:
- providing a plurality of illuminators, each illuminator comprising a light emitting side, and each illuminator being connected to a common circuitry carrier,
- providing an imaging module connected to the circuitry carrier, the imaging module comprising a lens for capturing images of an eye,
- embedding the plurality of illuminators, the imaging module and the circuitry carriers without gaps in a first material, wherein the first material is non-transparent to the illuminator light and wherein the first material comprises at least one opening filled with a second material, wherein the second material is transparent to IR light but non-transparent to visible light.
