Abstract: An optical device includes a first electrode and a medium that includes ferroelectric liquid crystals and chiral dopants. The medium is located adjacent to the first electrode. The optical device may also include a second electrode distinct and separate from the first electrode. The optical device may be used as an optical dimming device, controlling an amount light passing through the optical device based on a voltage gradient provided to the optical device.

Abstract: A headset for augmented reality applications is provided. The headset includes at least one eyepiece configured to provide a see-through image to a user via a transparent optical component, and to provide an artificial image through a display, and a dimming shutter configured to adjust a transparency level of the transparent optical component. The dimming shutter further includes an active liquid crystal layer configured to adjust a transparency level according to an electrical power provided between two electrodes, and a photoactive layer configured to adjust the transparency level upon absorption of an ultraviolet radiation for a selected period of time. A default orientation of a host material in the active liquid crystal layer may be in a dark state or in a clear state, when no electrical power is provided. A method and a memory storing instructions to execute the method for use of the above device are also provided.

Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for interaction controls in artificial reality. Various aspects may include determining at least one element corresponding to a user device for accessing a shared artificial reality environment. Aspects may also include determining at least one artificial reality setting associated with the shared artificial reality environment. Aspects may include receiving an indication of a permission event associated with a permitted user or a temporal parameter. Aspects may include determining whether to enable or disable the at least one element or at least one artificial reality setting based on the permission event. The aspect may also include sending content to the user device based on the permission event.

Abstract: An optical dimming device is provided. The optical dimming device includes a photochromic element including a photochromic composition. The photochromic composition includes a combination of a first photochromic material and a second photochromic material having different steady-state absorption profiles. In a direction from a first portion to a second portion of the photochromic element, a concentration of the first photochromic material in the combination decreases and a concentration of the second photochromic material in the combination increases.

Abstract: A device includes an optical assembly and a digital projector. The optical assembly is configured to receive visible scene light at a backside of the optical assembly and to direct the visible scene light on an optical path toward an eyeward side. The optical assembly includes a dimming layer disposed on the optical path. The dimming layer includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. The digital projector is disposed on the eyeward side of the optical assembly and is configured to selectively emit an activation light within the range of light wavelengths to activate a darkening of a region of the dimming layer to dim the visible scene light within the region.

Abstract: A switchable polarizer includes a transparent layer and switchable material layer. The switchable material layer includes strips of a switchable material that are arranged to polarize incident light propagating through the transparent layer when the switchable material is heated to a threshold switching temperature. The incident light propagating through the transparent layer is unpolarized by the strips of the switchable material when the switchable material is below the threshold switching temperature.

Abstract: A near-eye display assembly presented herein includes an electronic display, an optical assembly, and scanning assembly. The electronic display has a first resolution. The optical assembly controls a field of view at an eye box and directs a plurality of light rays emitting from the electronic display toward the eye box. The scanning assembly shifts a direction of at least one of the light rays in accordance with emission instructions such that a virtual display is presented to the eye box, the virtual display having a second resolution greater than the first resolution. The display assembly can be implemented as a component of a head-mounted display of an artificial reality system.

Abstract: A device includes a display including multiple pixels, each pixel having an optical emitter to provide at least one light beam from an image. The device also includes an optical element to relay light beams from the display to a viewer through an eyebox, the eyebox limiting an area that includes a pupil of the viewer and a varifocal assembly to direct, through the eyebox, light beams having a first and second mutually orthogonal polarization states, according to a desired mode of operation of the device, and associated with a first and second field of view of the image in a focused mode of operation of the device, and an immersive mode of operation of the device, respectively. A memory storing instructions and a processor to execute the instructions to cause the device to perform a method for adjusting between the immersive mode and the focused mode are also provided.

Abstract: An optical element includes a first layer, a second layer, and a fluid. A first surface of the first layer is configured to change hydrophobicity in response to incoming activation light. Absorbing molecules in the fluid are repelled or attracted to the first surface in response to the hydrophobicity of the first surface.
