Abstract: The present disclosure is related generally to techniques for improving the performance and efficiency of display systems, such as laser scan beam display systems or other types of display systems (e.g., micro-displays) of an HMD system or other device. Display systems of the present disclosure may utilize polarization multiplexing that allow for improved optimization of diffraction optics. In at least some implementations, a display system may selectively polarize light dependent on wavelength (e.g., color) or field of view. An optical combiner may include polarization sensitive diffractive optical elements that are each optimized for a subset of colors or portions of an overall field of view, thereby providing improved correction optics for a display system.

Abstract: A trained machine learning model(s) is used to determine scores indicative of probabilities that certain types of user input will be provided to a player's game controller while playing a video game in order to compensate for latency between player action and player perception of video game content relating to the player action. In an example process, sensor data received from a client machine and/or game state data received from a video game is provided as input to a trained machine learning model(s), and a score as output therefrom, the score relating to a probability that a type of user input will be provided to a player's game controller. In this manner, game control data corresponding to the type of user input can be generated based on the score and provided to the video game as input before actual game control data is even received, thereby compensating for latency.

Abstract: A multi-coil voice coil motor (VCM) may be configured to be used as a haptic actuator for providing haptic feedback to a user. When implemented in a handheld controller having one or more controls, the multi-coil VCM may be configured to provide haptic feedback to a user of the controller. The multi-coil VCM may include a housing, multiple concentric coils, and a magnet coupled to the housing. The multiple concentric coils may include a first coil disposed on a first support coupled to the housing and a second coil disposed on a second support coupled to the housing, wherein the multiple concentric coils may have different diameters to allow for the concentricity of the coils. A system may include one or more haptic actuators, such as the multi-coil VCM, the haptic actuator(s) being configured to provide haptic feedback by causing at least a portion of a finger-operated control(s) to vibrate.

Abstract: An optical system of a head-mounted display (HMD) system that includes a diffractive optical element coupled to a display, for example, via lamination or a suitable optically clear adhesive. The optical system may include a reflective polarizer and a quarter-wave plate that, together with the diffractive optical element, form a catadioptric or “pancake” configuration that focuses light from a display system to an eye of a user of the head mounted display system.

Abstract: Systems and methods for tracking the position of a head-mounted display (HMD) system component. The HMD component may carry a plurality of angle sensitive detectors that are able to detect the angle of light emitted from a light source. The HMD component may include one or more scatter detectors that detect whether light has been scattered or reflected, so such light can be ignored. Control circuitry causes light sources to emit light according a specified pattern, and receives sensor data from the plurality of angle sensitive detectors. The processor may process the sensor data and scatter detector data, for example using machine learning or other techniques, to track a position of the HMD component. An angle sensitive detector may include a spatially-varying polarizer having a position-varying polarizing pattern and one or more polarizer layers that together are operative to detect the angle of impinging light.

Abstract: Systems and methods for providing a display for an electronic device that includes a liquid crystal display panel assembly, a backlight assembly that includes a light source, and a spatially varying polarizer that provides phase retardation that varies as a function of propagation length away from the light source. The display may also include a linear polarizer and other optical components that improve the efficiency of the backlight assembly, thereby reducing power consumption, cost, space requirements, and provide other advantages.

Abstract: Described herein are controllers with sensor-rich controls for enhanced controller functionality. An example control may include a pressure sensor that is configured to detect an amount of a force of a press on a cover of the control based at least in part on a proximity of a metal layer to the pressure sensor. This control may further include a touch sensor for detecting an object contacting the cover of the control. Additional embodiments disclose, among other things, integrated trackpads and D-pads, as well as backlighting features that indicate a functional state of the controller.

Abstract: The present disclosure relates generally to techniques for improving the performance and efficiency of optical systems, such as optical systems for using head-mounted display system. The optical systems of the present disclosure may include polarized catadioptric optics, or “pancake optics,” which utilize a wire grid polarizer as a reflective polarizer. Wire grid polarizers may not perform uniformly over wavelength or over varying angles of incidence. To improve performance, a spatially varying polarizer is provided in the optical system that operates to provide polarization compensation for the wire grid polarizer so that the wire grid polarizer performs more uniformly over wavelength and/or over incidence angles (e.g., on-axis and off-axis). The spatially varying polarizer may be formed of a liquid crystal material, such as a multi-twist retarder.

Abstract: Described herein are, among other things, techniques, devices, and systems for generating one or more trained machine-learning models used for generating content-item recommendations. Also described herein are techniques, devices, and systems for applying a consumption history of a particular user to the trained model(s) to generate score data indicating a correlation between each content-item title and the consumption history, as well as modifying this score data using one or more biasing factors for generating result data. In addition, the techniques, devices, and systems may use this result data, along with received user input, for determining an order in which to present one or more content items to the user. For example, this may include determining which content items to recommend to a user and in which order to do so.
