Abstract

An eye tracking system employing three-dimensional (3D) sensing using time of flight is provided. Instead of directly measuring the time of arrival of the emitted photons, the light intensity of the transmitted laser beam is modulated, and a phase change of the return beam computed by comparison with the transmit waveform. The modulation frequency is resolved with radio frequency (RF) mixing and digital signal processing techniques. A variety of phase detection systems and techniques including, but not limited to, quadrature analog front end detection and analog homodyne phase detection are applied. The modulation frequency may, depending on phase detection technique, be sinusoidal or pulsed.

Abstract

A processor accesses a depth map and a first image of a scene generated using one or more sensors of an artificial reality device. The processor generates, based on the first image, segmentation masks respectively associated with a plurality of object types. The segmentation masks segment the depth map into a plurality of segmented depth maps respectively associated with the object types. The processor generates meshes using, respectively, the segmented depth maps. For each eye of the user, the processor captures a second image and generates, based on the second image, segmentation information. The processor warps the plurality of meshes to generate warped meshes for the eye, and then generates an eye-specific mesh for the eye by compositing the warped meshes according to the segmentation information. The processor renders an output image for the eye using the second image and the eye-specific mesh.

Abstract

A projector sequentially generates light pulses to form a sparse grid array. The light pulses reflect off objects in an environment and are reflected towards a sensor array. The sensor array sequentially senses the reflected light pulses across pixels of the sensor array. A depth sensing system calculates depth information of objects in the environment based on the sequential nature of the pulse generation and the pulse sensing. The depth sensing system calculates depth information based on both the positional and temporal information of generated light pulses, and the positional and temporal information of sensed light pulses. The depth sensing system may generate a representation of the environment based on the depth information.

Abstract

Methods and corresponding systems and apparatuses for saving power through selectively disabling clock signals in a systolic array are described. In some embodiments, a clock gate controller is operable to output a gated clock signal from which local clock signals of processing elements in the systolic array are derived. The gated clock signal corresponds to a root clock signal that is distributed through a clock distribution network or clock tree. The clock gate controller is located along one branch of the clock distribution network. The branch can be associated with processing elements that form a column within the systolic array. Disabling the gated clock signal disables the local clock signals along the entire branch, preventing any components that are clocked by those local clock signals from consuming power. Additional clock gate controllers can similarly be provided for other branches, including a branch associated with another column.

Abstract

Aspects of the present disclosure are directed to creating virtual doors within artificial reality (XR) universes for traversal within that XR universe and between other XR universes. Users can create virtual doors that control access to their privately owned property (e.g., world, parcel, house, etc.) in an XR universe. For example, an owner of a virtual door can manually lock the door to prevent any user from entering their property through the virtual door. As another example, an owner of a virtual door can configure door permissions and/or privacy settings that serve as heuristics by which a door access control manager determines whether to authorize a particular user, XR world, and/or XR universe to access. The XR universe traversal system can control an execution environment to smoothly transition between different applications, thereby enabling a user to traverse between different XR universes without having to leave the XR environment.

Abstract

A camera assembly with two distinct magnifications is described. The camera assembly includes a lens assembly with two modules to perceive light. The first module includes two halves of different lens assemblies disposed together to provide two different optical paths and fields of view to obtain the two different optical magnifications. The second module includes a lens assembly common to the two halves of the first module. A biprism provides light separation for the two halves of the first module. Thus, light received and subjected to two different magnifications in the first module at a distal end of the camera assembly is further processed through the second module before being provided to a sensor. The biprism at the camera's distal end keeps the two different lens assemblies of the first module at the same viewing direction.

Translating Interactions on a Two-Dimensional Interface to an Artificial Reality Experience

Abstract

Many users access artificial reality (XR) experiences through their mobile phones. However, it is difficult to translate XR experiences to a two-dimensional (2D) screen in a way that feels intuitive and natural. Thus, the technology can map an interaction plane in a three-dimensional (3D) scene to the 2D screen with as many affordances as possible, even if the plane is not parallel to the mobile phone. The plane can be a fixed surface or a dynamically changeable surface through which the user sends inputs through the 2D screen. The mapping of the plane to the 2D screen can control interaction with a virtual object on the interaction plane in the XR environment, enabling parity between the same experience on XR and non-XR interfaces.

Abstract

In particular embodiments, a computing system may access a particular image frame and corresponding depth information of a dynamic scene. The depth information is used to generate a point cloud of the particular image frame. The system may generate a first latent representation based on the point cloud. The system may access a sequence of image frames of the dynamic scene and a set of key frames. The system may generate, using a temporal transformer, a second latent representation based on tracking and combining temporal relationship between the sequence of image frames and the set of key frames. The system may access camera parameters for rendering the one or more objects from a desired novel viewpoint and generate a third latent representation. The system may train an improved neural radiance fields (NeRF) based model for free-viewpoint rendering of the dynamic scene based on the first, second, and third latent representations.

Abstract

A speaker produces acoustic frequencies within a housing that outputs the acoustic frequencies to a port. The produced frequencies travel through a cavity to the port which may have a cavity resonance that amplifies certain frequencies, affecting the frequency sensitivity of the speaker. To mitigate the cavity resonance, the speaker includes a membrane with regions having different breakup frequencies. One region is tuned to break up at a desired bandwidth of the speaker, and another region is tuned to break up at the cavity resonance, mitigating the distortion on frequency response due to the cavity resonance.

A leaky-mode acousto-optical modulator may be used to generate visual images suitable for direct viewing, without image-forming optics. To extend a field of view of the modulator to limits suitable for visual displays, the leaky-mode acousto-optical modulator may be equipped with a switchable beam redirector, e.g. a switchable-angle reflector, providing field of view portions one by one in a time-sequential manner. The field of view portions coalesce into a continuous synthetic field of view suitable for wide-angle visual display applications.

Abstract

An eye tracking system with in-optical-assembly plane illumination is described. Side-emitting light emitting diodes (LEDs) aligned with a plane of an optical assembly of a near-eye display device are used to illuminate the eye of a user and generate glints that can be detected by an eye tracking camera. When a corrective optical lens or similar element is included in the optical assembly that may distort illumination beams from the light emitting diodes (LEDs), the distortion is mitigated by using in-package or externally modified LEDs that provide angled beams. In addition to in-package level mitigations such as reflectors or labels, edge portions of the distorting optical elements may be shaped or complemented with refractive elements to redirect the beams toward the eye.

Abstract

A liquid lens with flexible transparent active layers on both sides of a fluid is transformed along two distinct deformation axes. The flexible transparent active layers include piezoelectric materials that actuate the lens in response to applied voltage(s). The piezoelectric properties and actuation mechanism of the transparent layers are arranged to deform the lens cylindrically along different axes resulting in a net spherical deformation or a combination of spherical and cylindrical deformation with substantially less distortion than spherically deforming layers. The piezoelectric active layers may be polymer or ceramic with isotropic or anisotropic mechanical stiffness. Alternatively, a pair of transparent, internal layers are positioned between the front and rear surfaces. The active layers, front and/or rear, are dual layers affixed together with an adhesive or single layers.
