Abstract: A method for updating a gaze direction for a transmitter avatar in a receiver headset is provided. The method includes verifying, in a receiver device, that a visual tracking of a transmitter avatar is active in a transmitter device, and adjusting, in the receiver device, a gaze direction of the transmitter avatar to a fixation point. Adjusting the gaze direction of the transmitter avatar comprises estimating a coordinate of the fixation point in a receiver frame at a later time, and rotating, in the receiver device, two eyeballs of the transmitter avatar to a point in a direction of the fixation point. A headset, a memory in the headset storing instructions, and a processor configured to execute the instructions to perform the above method, are also provided.

Abstract: There is provided a photonic integrated circuit configured for low-coherence interferometry and in-field sensing. The photonic integrated circuit can include an opto-coupler that has a substrate substantially transparent to a specified wavelength of light and a waveguide configured to route a light beam having a center wavelength at the specified wavelength. The opto-coupler further includes a mirror disposed at an angle, and the mirror is disposed on an angled surface of the substrate, the angled surface being proximate to an output end of the waveguide. The opto-coupler further includes a beam forming element configured to collect light reflected from the mirror, and the waveguide and the mirror are integrated within the substrate.

Abstract: Embodiments relate to an audio system that performs equalization of audio signals based on one or more diffuse field head-related transfer functions (HRTFs) and device-specific data. User-specific data and device-specific data (i.e., transducer-specific data) are applied to an acoustic model to predict an acoustic response for a user. An equalization filter is then determined using the acoustic response and the one or more diffuse field HRTFs. The equalization filter is applied to a processed version of an audio signal to create a modified version of the audio signal. The modified version of the audio signal is presented to the user via a transducer array of the audio system. The audio system can further include a microphone assembly that reduces the Helmholtz resonance effect.

Abstract: Disclosed herein are related to systems and methods for providing inputs through a virtual keyboard with an adaptive language model. In one approach, one or more processors determine whether a user intended to provide semantically meaningful characters or not, when providing a hand motion or a hand pose with respect to a virtual keyboard. The virtual keyboard may be located on a surface without physical keys. In one approach, the one or more processors determine an input to the virtual keyboard based on the hand motion or the hand pose. In one approach, the one or more processors determine weight of a language model according to the determined user intention. In one approach, the one or more processors modify the detected input according to the determined weight of the language model.

Abstract: A source-camera assembly with an isolated light path for a reference pixel is described. The assembly may include a projector, a camera assembly, a reference waveguide, and an overmold. The projector may include a source array configured to emit light and a lens assembly configured to direct the light into a local area. The camera assembly may include a sensor and a reference pixel. The sensor may be configured to detect the emitted light reflected from an object within the local area. The reference waveguide is configured to guide a portion of the light emitted by the projector from the source array to the reference pixel. The light detected by the sensor and the light detected by the reference pixel may be used to determine depth information for the object. The overmold is opaque to the emitted light and covers portions of the projector, the camera assembly, and the reference waveguide.

Abstract: Aspects of the present disclosure are directed to creating interactive avatars that can be pinned as world-locked artificial reality content. Once pinned, an avatar can interact with the environment according to contextual queues and rules, without active control by the avatar owner. An interactive avatar system can configure the avatar with action rules, visual elements, and settings based on user selections. Once an avatar is configured and pinned to a location by an avatar owner, when other XR devices are at that location, a central system can provide the avatar (with its configurations) to the other XR device. This allows a user of that other XR device to discover and interact with the avatar according to the configurations established by the avatar owner.

Abstract: An example apparatus may include a display and an optical configuration configured to provide an image of a display, for example, in a head-mounted device. An example apparatus may include a display, a first lens assembly including a lens and a reflector, and a second lens assembly including a second lens and a second reflector. In some examples, the first lens assembly has a front surface configured to receive display light from the display when the display is energized. The first lens assembly may include a Fresnel surface (e.g., a Fresnel surface including facets and steps) that may, for example, be formed in a lens surface, or in the surface of a substrate supported by a lens surface. Other devices, methods, systems and computer-readable media are also disclosed.

Abstract: A method for manufacturing LED devices is provided. The method comprises forming an epitaxial layer on a starter substrate, the epitaxial layer having a first surface that interfaces with the starter substrate and a second surface opposite to the first surface; establishing an adhesive bond between the second surface of the epitaxial layer and a carrier substrate having a pre-determined light transmittance; etching away the starter substrate; etching away part of the epitaxial layer to form a plurality of light emitting diode (LED) dies on a third surface of the epitaxial layer opposite to the second surface; establishing one or more conductive bonds between selected one or more LED dies, from the plurality of LED dies, and a backplane; weakening the adhesive bond between the second surface of the epitaxial layer and the carrier substrate; and moving the carrier substrate away from the backplane.

Abstract: A waveguide display includes a substrate transparent to visible light, a first grating on the substrate and configured to couple display light into or out of the substrate, and a phase structure on the substrate and configured to change a polarization state of the display light after or before the display light reaches the first grating. The first grating is characterized by a polarization-dependent diffraction efficiency. The first grating includes, for example, a surface-relief grating or a volume Bragg grating.
