Authentic Eye Region Capture through Artificial Reality Headset
In holographic calling, it is difficult to capture the eyes of a caller due to lighting effects on an artificial reality (XR) headset. However, it can be important to capture the eyes when rendering the caller as they can show emotion, gaze, physical characteristics, etc., that aid in natural communication. Thus, implementations can capture the eyes of the caller using an external image capture device by briefly turning off the lighting effects on the XR headset. Some implementations can trigger the image capture device to capture an image of the eyes by temporal multiplexing in which timers on both the image capture device and the XR headset are synchronized. In other implementations, the image capture device can be an event-based camera that is automatically triggered to capture an image of the eyes based on a detected pixel change caused by deactivation of the lighting effects on the XR headset.
Implementations can provide a virtual separate space with respect to a virtual venue hosting a virtual reality (VR) experience, such as a concert, a sports game, a meeting, etc., e.g., to replicate the feeling of a side conversation to discuss the VR experience. Some implementations can create a more intimate experience for users viewing a VR experience by providing a quiet, curated space that can be customized, e.g., by changing the look of users' avatars and their virtual environment, without their interactions being observed by others viewing the VR experience at the virtual venue. The virtual separate space can include a moderated version of the VR experience, such as a smaller version of the VR experience with the sounds of the VR experience muffled. Thus, users within the virtual separate space can step away from the VR experience to enter a more controlled environment, while still enjoying the VR experience.
Techniques are described for backlighting electronic headset display panels. The method can include emitting light from a light source. The light can be transmitted from the light source via a light transmitting element to illuminate a light guide plate that is located remotely from the light source. The light guide plate can illuminate a display panel that is located remotely from the light source. A photodiode can detect a characteristic of the light that is transmitted by the light transmitting element at a location proximate the display panel and remote from the light source. One or more processors can determine a power level of the light source that is based at least in part on the characteristic detected by the photodiode.
A display system includes a wearable eyewear arrangement with a projector for propagating display light associated with an image and a waveguide for propagating the display light to an eye box. The waveguide includes volume Bragg gratings (VBGs), which may be in groups of three or more gratings with same horizontal period allowing each color to be coupled out from the waveguide by the same type of grating, thus, at the same angle, reducing or eliminating image blurriness and ghost images while allowing a smaller size waveguide. A 100% reflective mirror or mirror array is used for broad spectrum reflection into the waveguide for light input. Selection of two or more wavelengths for each color at the projector provides spectral response matching to the waveguide allowing wider field of view (FOV) coverage for the entire wavelength spectrum.

The beam shaping element may be a diffractive optical element (DOE), with an angle and shape of diffractors selected based on a designated direction and spread of beam shaped light.
A transparent combination antenna is disclosed that provides bandwidth at both sub 6 GHz and the above 24 GHz spectra. For example, the transparent combination antenna can include a first layer of transparent conductive material, and a second layer of transparent conductive material.

Additionally, in some implementations, a substrate may be positioned in between the first layer and the second layer. Various other systems are also disclosed.
For electronic devices that have an electrically conductive surface across a gap from a battery enclosure, the described circuit may be used to detect an anomalous event.

The system may determine an impedance across the resistor and may use the measured impedance to detect and/or classify an anomalous event.

A multilayer polymer thin film includes an anti-reflective coating directly overlying a reflective polarizer stack. The reflective polarizer stack includes alternating first and second polymer layers, where the first layers include an isotropic polymer thin film and the second layers include an anisotropic polymer thin film. The anti-reflective coating (ARC) includes alternating third and fourth layers, where the third layers include an isotropic polymer thin film or an anisotropic polymer thin film and the fourth layers include an isotropic polymer thin film. The multilayer polymer thin film may be formed by co-extrusion where the reflective polarizer stack and the anti-reflective coating are formed simultaneously.
An audio device includes a first speaker and a second speaker. A front surface of a membrane of the second speaker faces a rear surface of a membrane of the first speaker. The membrane of the first speaker moves in an opposite direction than the membrane of the second speaker when the audio device outputs audio content. This configuration maintains isobaric pressure for a back volume shared between the first speaker and the second speaker, reducing vibration of the audio device when outputting audio content.
