Abstract

A user uses “snap points” to activate virtual objects and/or to transition virtual objects from body-locked or head-locked (i.e., “leashed”) to world-locked. A snap point is a specific location in the user's artificial-reality (XR) world. When the user assumes a position near to where he was when he previously defined a snap point, the object ceases to be leashed and instead locks to the snap point (i.e., the object becomes “world-locked”). Until the user's distance from where he was when he defined the snap point exceeds a threshold value, the object remains stably world-locked at the snap point. When the user moves more than the threshold, the object releases from the snap point, returns to its previously defined leashed mode, and follows the user through the XR world as previously.

Abstract

A device includes a micro-organic light emitting diode (µ-OLED) display panel and an electronic component. An electrical connector electrically couples the µ-OLED display panel and the electronic component. A standoff is disposed between the electronic component and the µ-OLED display panel. The standoff physically couples the electronic component and the µ-OLED display panel with a gap therebetween. The gap thermally decouples the electronic component from the µ-OLED display panel. A fan that is integrated with the µ-OLED display panel is placed in the standoff and actively cools the display panel. When the fan provides air flow over the µ-OLED display panel, heat generated by the µ-OLED display is mitigated by cooling air.

Abstract

A recording device provides bystander-centric privacy controls for authorizing the storage of a bystander's identifying information (e.g., video or audio recordings of the bystander). Before a recording device can store identifying information of bystanders, the bystanders may indicate to the recording device whether they authorize the storage. If the bystanders do not authorize the storage, the recording device may modify the identifying information captured by sensors, such as a video camera or a microphone, such that the identity of the non-authorizing bystander is not identifiable through the modified identifying information. Thus, bystanders are given increased agency over whether they want to be recorded. Further, if the bystanders do not want to be recorded, sensor data that may identify them is modified by the recording device to prevent unwanted exposure of their identity in recorded content.

Abstract

A tracking device monitors a portion of a user's skin to infer a pose or gesture made by a body part of a user that engages the portion of the user's skin as the pose or gesture is made. For example, the tracking device monitors a portion of skin on a user's forearm to infer a pose or gesture made by the user's hand. The tracking device may include an illumination source that illuminates the portion of the user's skin. An optical sensor of the tracking device may capture images of the illuminated portion of skin. A controller of the tracking device infers a pose or gesture of the body part based in part on a model (e.g., a machine-learned model) and the captured images. The model may map various configurations of the user's skin to different poses or gestures of the body part.

Abstract

The invention is directed towards enhanced systems and methods for employing a pulsed photon (or EM energy) source, such as but not limited to a laser, to electrically couple, bond, and/or affix the electrical contacts of a semiconductor device to the electrical contacts of another semiconductor devices. Full or partial rows of LEDs are electrically coupled, bonded, and/or affixed to a backplane of a display device. The LEDs may be μLEDs. The pulsed photon source is employed to irradiate the LEDs with scanning photon pulses. The EM radiation is absorbed by either the surfaces, bulk, substrate, the electrical contacts of the LED, and/or electrical contacts of the backplane to generate thermal energy that induces the bonding between the electrical contacts of the LEDs' electrical contacts and backplane's electrical contacts. The temporal and spatial profiles of the photon pulses, as well as a pulsing frequency and a scanning frequency of the photon source, are selected to control for adverse thermal effects.

Abstract

A varifocal liquid lens includes a body filled with two different fluids separated by an interface of a variable curvature across a clear aperture of the varifocal liquid lens. At least one of the first or second fluids is birefringent, such that a refractive index difference between the first and second fluids and resulting optical power of the varifocal liquid lens is dependent on polarization of impinging light. At a first light polarization, the first and second fluids may be matched in refractive index, while at a second, orthogonal light polarization, the first and second fluids may be mismatched in refractive index, whereby the first interface between the first and second fluids may have a variable, non-zero optical power for the second polarization while having a substantially non-variable, zero optical power for the first polarization of light.

A recording medium includes matrix polymer precursor, inimer comprising a polymerizable functional group and a controlled radical reactive group, photoinitiator more reactive with the polymerizable functional group than the controlled radical reactive group in the presence of an excitation source, and a photoredux catalyst. The medium is cured to form a support matrix. The medium is exposed to the excitation source, forming a latent grating having bright fringes and dark fringes. Polymerized inimer is more concentrated in the bright fringes than in the dark fringes. A high refractive index monomer reactive with the controlled radical reactive group is diffused into the medium and exposed to light to cause controlled radical polymerization between the high refractive index monomer and the controlled radical reactive group of the polymerized inimer, driving up a refractive index of the bright fringes relative to the dark fringes.

Abstract

Recording a volume Bragg grating is effectuated by a recording medium formed from a matrix polymer precursor including a controlled radical reactive group, a photoactive base monomer, and a photoinitiator system more reactive with the photoactive base monomer than the controlled radical reactive group in the presence of an excitation source, and a photoredox catalyst. The medium is cured thereby forming a support matrix from the matrix polymer precursor. Exposure to the excitation source through a pattern causes the photoinitiator to polymerize the base monomer, forming a latent grating of the Bragg grating. The latent grating has bright and dark fringes determined by the pattern. The concentration of polymerized base polymer is higher in the bright fringes than in the dark fringes. The exposing causes a portion of the matrix to diffuse into the dark fringes. The support matrix has a lower refractive index than the polymerized photoactive base monomer.

Abstract

A near eye display (NED) includes multiple PBP optical elements combined with one or more C-plates to improve optical angular performance. The PBP optical elements may be configured for beam steering or for focusing light to a point. A C-plate may reduce or eliminate an undesirable polarization phase shift introduced by the PBP optical elements to angular, off-axis light. Birefringence of the PBP optical elements produces such a polarization phase shift. A C-plate provides an additional polarization phase shift that is opposite to the extra polarization phase shift by the PBP optical elements. Thus, the additional polarization phase shift by the C-plate at least partially reduces the phase shift by the PBP element.

Abstract

A liquid lens includes a substrate, a transparent elastic membrane forming a cavity with the substrate, and a transparent fluid filling the cavity between the substrate and the membrane. The membrane has a pre-distorted, rotationally asymmetric shape in absence of the fluid in the cavity. When the cavity is filled with the fluid and the substrate is disposed vertically w.r.t. gravity at a pre-defined clocking angle, the membrane adopts a substantially rotationally symmetric shape due to elasticity of the membrane counteracting gravity exerting a downward force on the fluid in the cavity, reducing the effect of the gravity sag on optical performance of the liquid lens.

In implementations, the offload device and client device are situated in a network such that a latency for the offload communications supports real-time video display. A gateway device manager can locate a gateway connected to the client device, and resources can be deployed (or the gateway can be prepopulated) so that the device can perform gateway services and edge processing services for the client device.

Abstract

A laser light is used to modify the surface of the gallium semiconductor layer of an LED. The parameters of the laser are selected so that the laser interacts with the gallium semiconductor layer in a desired manner to yield the desired surface properties. For example, if a particular surface roughness is desired, the power of the laser light is selected so that the laser light penetrates the gallium semiconductor layer to a depth matching the desired surface roughness. The same principles can also be applied in a process that creates features such as trenches, pits, lenses, and mirrors on the gallium semiconductor layer of an LED. The laser projector is operated to irradiate a region of the gallium semiconductor layer to create a region of metallic gallium. The desired surface roughness and the different features can advantageously improve the beam collimation, light extraction, and other properties of the LED.

Abstract

A beam scanner and a display device is based on a photonic integrated circuit coupling light to a pair of opposed reflectors. One reflector is tiltable and has an opening through which the light is coupled, and the other reflector is configured to focus light, e.g. a concave reflector. A polarization folding configuration is used to cause the focused light propagate through the opening in the first reflector, get collimated by the second reflector, get scanned by the first reflector, and propagate through the second reflector to a pupil-replicating lightguide which provides multiple laterally offset parallel portions of the scanned beam.

Abstract

A beam scanner of a projector-based near-eye display includes a prismatic element with a reflective polarizer and a quarter-wave waveplate (QWP). The beam-folding prismatic element receives a polarized light beam from a light source and couples the beam to a tiltable reflector, e.g. a 2D tiltable MEMS reflector, for angular scanning the beam. The light beam impinging onto the tiltable reflector is separated from the light beam reflected from the tiltable reflector by polarization. The polarization-based separation is achieved by causing the light beam to propagate through the QWP before and after impinging onto the tiltable reflector. Upon double propagation of the light beam through the QWP, the beam changes its polarization to an orthogonal polarization, which enables its separation from the impinging beam. The beam scanner may receive multiple light beams from multiple light sources. A projector and a near-eye display based on such beam scanners are also disclosed.

Abstract

A rhythm-based video game (“game”) is disclosed. In the game, a player slashes blocks representing musical beats using a pair of energy blades resembling a lightsaber. A gaming console renders multiple digital objects, e.g., digital blocks, digital mines and digital obstacles, that are approaching a player in a virtual space. The gaming console also renders a digital representation of an instrument, e.g., a lightsaber (“digital saber”), using which the player slashes, cuts or otherwise interacts with the digital blocks to cause a digital collision between the digital saber and the digital blocks. The player can score by slashing the digital blocks, not hitting the digital mines and avoiding the digital obstacles. The game presents the player with a stream of approaching digital objects in synchronization with music, e.g., a song's beats, being played in the game. The pace at which the digital blocks approach the player increases with the beats.
