Optical halo system for peripheral light extension in head-mounted displays (VR / AR / MR)

Abstract

Optical halo system for peripheral light extension in head-mounted displays (VR / AR / MR), characterized in that a halo element is arranged in the peripheral area of ​​the head-mounted display, which generates a circumferential or segmented light area in the peripheral field of vision.

Description

1. Technical field

[0001] The invention relates to optical and lighting systems for extending and shaping the peripheral field of view in head-mounted displays for VR / AR / MR. The invention includes passive, active, and combined designs in which a halo or a surrounding light area is generated in the peripheral region. 2. State of the art.

[0002] Head-mounted displays are known for their visible edges, masking, and harsh transitions in the peripheral field of vision. Also common are lighting and light guidance systems, as well as accessory solutions that optically illuminate or modify peripheral areas. These solutions are often either purely passive, without controlled light output, or purely active, with a separate light source.

[0003] However, a system family that can be implemented passively, actively and in combination, thereby creating an optical halo in the peripheral field of vision of a head-mounted display, where geometry, material, mounting and power supply can be realized as variants within a unified system concept, is not known. 3. Object of the invention

[0004] The object of the invention is to provide a system that can generate an optical halo in the peripheral field of vision of a head-mounted display in order to visibly expand, soften, or color the peripheral area. The system should be implementable in various designs and be available as a passive, active, or combined system. 4. Solution to the task

[0005] The task is accomplished by a halo system positioned in the peripheral area of ​​a head-mounted display, generating a surrounding or segmented light field. The halo system can be implemented as a passive optical element (e.g., a light-guiding or diffusing structure), as an active lighting system (e.g., an LED or segmented lighting system), or as a combination of passive optics and an active light source. The halo system can be permanently integrated, retrofittable, or designed as an add-on / clip. 5. Designs

[0006] The execution can be carried out in particular as: a) Passive systems: A passive design uses optical elements for light guidance, light control, or light scattering, e.g., light-guiding mats, prisms, or microstructures. The halo can be circumferential, partially circumferential, or segmented. b) Active Systems: An active design uses light sources to generate the halo, e.g., LEDs, micro-LEDs, or addressable segments. The light can be emitted directly or guided via optical fibers and extracted at the periphery. c) Extended Systems An extended version may include sensors or software processing to adapt the color, brightness, or dynamics of the halo to image elements, states, or signals. d) Power supply: An active or extended version can be powered via batteries, USB, induction or headset power. e) Fasteners and adapters The system can be attached magnetically, mechanically, via clip systems, Velcro, or frame adapters. It can be designed as a ring, C-shape, 360-degree halo, segmented halo, or diffused ring. f) Materials The system can consist of silicone, polycarbonate, TPU, as well as micro- and nanodiffuser structures. Material combinations are possible. 6. Operating principle

[0007] The operating principle involves creating a halo in the peripheral field of vision. This can be achieved through passive light guidance and scattering, active light emission, or a combination of light source and optical structure. The halo can be static or dynamic. 7. Advantages

[0008] The invention enables peripheral optical enhancement and customization of the field of view for head-mounted displays. The availability of passive, active, or combined systems allows for adaptation to different devices, designs, and mounting methods. The system can be used for optical enhancement, edge customization, or color customization.
