Abstract: Described herein is a broadband haptic system for a controller of a controller system to provide enhanced haptic functionality. A control, such as a trackpad, of the controller may include a cover, a circuit board disposed behind the cover and coupled to the cover, a haptic actuator mounted to the circuit board, and a spring disposed behind the cover, the spring being coupled to the cover and mounted to a housing of the controller. The haptic actuator is configured to vibrate and the spring is configured to deflect bidirectionally in response to a vibration of the haptic actuator. Furthermore, the haptic actuator has a first resonant frequency, and the control has a second resonant frequency different than the first resonant frequency to provide a broadband haptic system for the controller.

Abstract: There may be large numbers of content items available at current content provider systems. Subsets of these content items may be eligible to participate in events, such as sales. A content provider system may determine content item eligibility for events using content item data and proactively query vendor systems for participation in such events. The content provider system may iteratively query vendor systems based on an ordered set of eligible content items. The content provider system may monitor content items for updated content items data and proactively query a vendor system if a content item becomes eligible for an event based on updated content item data. Content items associated with a sale may be sorted and presented to a user based on user and/or content item data.

Abstract: A handheld controller may include controls that are actuatable by a user. The handheld controller may further include one or more sensors that are configured to detect an object in proximity to certain controls, and/or that sense a grip or position of a hand on a handle portion of the controller. Based on data from a sensor(s), certain controls may be enabled and/or disabled. The sensors may therefore be used to determine which controls are being used or are intended to be used, and/or which controls are likely accessible or inaccessible to the user based on sensor data, and to cause one or more controls of the handheld controller to be enabled and/or disabled accordingly.

Abstract: The present disclosure 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). Display systems of the present disclosure may include a polarization compensation optic, such as a spatially varying polarizer, that provides phase retardation that varies as a function of position, which provides polarization compensation to provide light that is well suited for a polarization sensitive optic of the display system, such as a waveguide-based optical system, a pancake optical system, a birdbath optical system, a coating-based optical system, etc. The display systems of the present disclosure may be components of head-mounted display systems, or other types of display systems.

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.

Abstract: Described herein are, among other things, techniques for implementing a dual detail encoding scheme in a distributed display system. At the host computer, an application may render a frame for a scene at a first resolution. The host computer may generate a two-dimensional (2D) array of pixels for the frame, encode the 2D array of pixels, and transmit the encoded pixel data to the display device. The 2D array of pixels comprises, for each eye, a copy of the frame downscaled to a second resolution less than the first resolution, and a copy of a subregion of the scene. At the display device, the encoded pixel data is decoded to obtain the 2D array of pixels for the frame, which is modified by enlarging the copies of the frame so that images can be generated using the enlarged copies of the frame and the copies of the subregion with blending.

Abstract: Systems and methods for tracking the position of one or more head-mounted display (HMD) system components of an HMD system. The HMD components may carry a plurality of angle sensitive detectors or other types of detectors. The HMD system may be operative to detect corrupted position tracking samples, allowing such samples to be ignored, thereby improving the position tracking process. Control circuitry causes light sources to emit light according a specified pattern, and receives sensor data from the plurality of detectors. Control circuitry may process the sensor data, for example using machine learning or other techniques, to track a position of one or more HMD components.

Abstract: An optical system is provided that includes a correction portion including one or more spatially varying polarizers. A first spatially varying polarizer of the one or more spatially varying polarizers has a first control input configured to receive a first control signal indicating whether the first spatially varying polarizer is to be active or inactive. When active, the first spatially varying polarizer is operative to provide a first optical correction on light passing through the correction portion. The optical system includes a controller configured to determine whether to implement the first optical correction on the light passing through the correction portion and in response to determining to implement the first optical correction on the light passing through the correction portion, output the first control signal indicating the first spatially varying polarizer is to be active. Additional spatially varying polarizers may be controlled to provide additional or alternative optical corrections.
