An example method is provided for applying a virtual lighting effect to virtual content based on ambient light associated with a real-world scene. The example method includes obtaining a measurement of ambient light associated with a scene of a real-world environment. The example method includes applying a virtual lighting effect to virtual content based at least in part on the measurement of the ambient light. And the example method includes causing display of the virtual content with the applied virtual lighting effect on a display of a computing device for displaying augmented reality, wherein the scene of the real-world environment is visible through the display.

Techniques for adaptively rendering virtual content n artificial reality environments based on ambient lighting of a real-world scene

A device for providing a reverse pass-through view of a user of a headset display to an onlooker includes an eyepiece comprising an optical surface configured to provide an image to a user on a first side of the optical surface. The device also includes a first camera configured to collect an image of a portion of a face of the user reflected from the optical surface in a first field of view, a display adjacent to the optical surface and configured to project forward an image of the face of the user, and a screen configured to receive light from the display and provide the image of the face of the user to an onlooker.

In one embodiment, a computing device may determine a virtual content to be displayed with a scene of a real-world environment. The device may generate an image depicting the virtual content. Using one or more sensors, the device may detect characteristics of the scene of the real-world environment. Based on the image and the characteristics of the scene, the device may determine that a visual enhancement is to be applied to the virtual content depicted in the image to enhance a contrast between the depicted virtual content and the scene. The device may generate a visually-enhanced image depicting the virtual content by applying the visual enhancement to the virtual content depicted in the image. The device may display the visually-enhanced image of the virtual content on a display of the computing device, wherein the scene of the real-world environment is visible through the display.

A device includes a polarization rotator configured to be switchable between operating in two switching states. The device also includes a controller configured to control the polarization rotator to switch between operating in the two switching states at a predetermined switching frequency, to thereby switch, a polarization of a component of an input light having an initial light intensity, between two orthogonal polarizations at the predetermined switching frequency. The device also includes a polarizer coupled with the polarization rotator, and configured to convert the input light transmitted through the polarization rotator into an output light having a light intensity reduced to a predetermined percentage of the initial light intensity of the input light.

Polarization-agnostic optical dimming device and optical assembly including the same

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.

A configurable occluder/dimmer for a near-eye display includes an array of polarization rotators and a polarization-selective scatterer downstream of the array of polarization rotators. The array of rotators and the polarization-selective scatterer are disposed between a pair of polarizers. The polarization-selective scatterer only scatters light at one of two orthogonal polarizations, thereby enhancing the achieved extinction ratio of the configurable occluder/dimmer. The configurable occluder/dimmer may be used in the near-eye display to provide occlusion effects rendering added virtual objects opaque, and/or to equalize contrast of the generated virtual imagery across the field of view of the display.

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.

An optical dimming device includes at least one polarization rotator configured to switch a polarization of a linearly polarized component of an incoming light between two orthogonal polarizations. The optical dimming device also includes at least one polarizer coupled with the at least one polarization rotator, and configured to output a light having a light intensity reduced to a predetermined percentage of an initial light intensity of the incoming light. The predetermined percentage is substantially the same for different incoming lights having different initial polarizations.

An 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 the eyeward side. The optical assembly also includes a dimming layer disposed on the optical path, where the dimming layer includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. An activation layer, included in the optical assembly, is also disposed on the optical path and includes an in-field dimmer. The in-field dimmer 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.

Local dimming in a device

The disclosed system may include a communication device configured to receive wireless synchronization information for display content, a lens, an optical device, and a controller configured to determine that the display content is in a field of view of the lens, and in response to determining that the display content is within the field of view of the lens, cause the lens to selectively allow the display content to pass through the lens based on the wireless synchronization information. Various other related methods and systems are also disclosed.

A virtual reality (VR) headset adjusts the phase of light of a virtual scene received from a display element using a spatial light modulator (SLM) to accommodate changes in vergence for a user viewing objects in the virtual scene. The VR headset receives virtual scene data that includes depth information for components of the virtual scene and the SLM adjusts a wavefront of the light of the virtual scene by generating a phase function that adjusts the light of the virtual scene with phase delays based the depth values. Individual phase delays shift components of the virtual scene based on the depth values to a target focal plane to accommodate a user at a vergence depth for a frame of the virtual scene. Further, the SLM can provide optical defocus by shifting components of the virtual scene with the phase delays for depth of field blur.
