Abstract: The invention concerns an optoelectronic apparatus comprising a light field pattern generating device with at least one light emitting element and at least one imaging optic, and a first sensor device, wherein the first sensor device is configured to determine the position of a body part, in particudefinilar the face, of a user of the optoelectronic apparatus relative to the light field pattern generating device, and wherein the light field pattern generating device is configured to generate at least one light field pattern on the body part of the user that is not directly visible to the user when looking in the direction of the light field pattern generating device, the light field pattern comprising at least a first area with a first illuminance and a second area with a second illuminance smaller than the first illuminance.

Abstract: An apparatus includes an information system with at least one pattern generator having a plurality of light nodes, each light node including at least one light emitting element, such as an LED. The at least one pattern generator is positioned with regard to a user of the apparatus such that it is located in the peripheral view of the user. A controller is operatively coupled to the pattern generator and configured to selectively initiate the generation of a visual light pattern on the pattern generator, the visual light pattern being indicative of information which is to be provided to the user of the apparatus.
