Abstract: A head-mounted display, or other near-to-eye display, incorporates optics that include a spatially-varying retarder (SVR). The SVR may be manufactured with a correction factor applied thereto in order to compensate for one or more manufacturing errors that are exhibited in a molded lens and/or a polarizing beam splitter included in the optics of the system.

Abstract: A force sensing resistor (FSR) that is constructed with a first substrate made of polyimide disposed underneath a second substrate that is resistive and flexible. A handheld controller for an electronic system may include the FSR having a first substrate made of polyimide. The FSR may be mounted on a planar surface of a structure within the controller body, such as a structure mounted within a handle of the controller body, and/or a structure that is mounted underneath at least one thumb-operated control that is included on a head of the controller body. The FSR may be configured to measure a resistance value that corresponds to an amount of force applied to an outer surface of the handle and/or an amount of force applied to the at least one thumb-operated control.

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: An augmented reality (AR) system allows for providing AR in video games. The disclosed AR system allows for layering AR content on top of the built-in features of video games to provide a unique “in-game” AR experience for gamers. A remote computing system provides a central data warehouse for AR content and related data that may be accessed by select client machines to render augmented frames with AR content during execution of video games. The AR content may be spatially-relevant AR content that is rendered at appropriate locations within a game world. The AR content may be event specific such that the AR content is added in response to game-related events. The disclosed AR system allows for adding multiplayer aspects to otherwise single player games, and/or sharing of AR content in real-time to provide augmentative features such as spectating, mixing of game worlds, and/or teleportation through AR objects.

Abstract: Described herein are, among other things, techniques to enable a user to navigate a color picker or other graphical-user-interface (GUI) tool using an input device of a handheld controller. For example, a user may operate a color picker presented on a display by pressing upwards on a joystick to activate selection of hue, down and to the left to activate selection of saturation, and down and to the right to activate selection of lightness or value.

Abstract: Light output of a display can be dynamically adjusted on-the-fly. When implemented on a low-persistence display that supports a variable refresh rate, this dynamic light output adjustment maintains a constant brightness over a series of frames to eliminate flickering of the display. When pixel data of a given frame is output to a frame buffer for presenting an image on the display, a time difference between an illumination of the display's light emitting elements for a preceding frame and an upcoming illumination of the light emitting elements for the given frame may be determined, and this time difference is used to determine a value of a light output parameter. During presentation of the image on the display, the light emitting elements can be illuminated in accordance with the value of the light output parameter. This determination iterates over a series of frames to dynamically adjust the display's light output.

Abstract: A head-mounted display (HMD) with a rolling illumination display panel can dynamically target a render time for a given frame based on eye tracking. Using this approach, re-projection adjustments are minimized at the location of the display(s) where the user is looking, which mitigates unwanted, re-projection-based visual artifacts in that “region of interest.” For example, logic of the HMD may predict a location on the display panel where a user will be looking during an illumination time period for a given frame, determine a time, within that illumination time period, at which an individual subset of the pixels that corresponds to the predicted location will be illuminated, predict a pose that the HMD will be in at the determined time, and send pose data indicative of this predicted pose to an application for rendering the frame.

Abstract: Systems and methods of providing stereo depth cameras for head-mounted display systems that require less memory and/or processing power. The stereo depth camera may include a left camera and a right camera spaced apart from each other by a distance. Each of the left and right cameras may be skewed outward by a non-zero angle from a forward direction of the head-mounted display system to provide a relatively wide field of view for the stereo depth camera. Each of the left and right cameras may include a camera sensor array and a camera lens positioned forward of the camera sensor array. Each of the camera lenses may include an optical axis that is laterally offset from the center of the associated camera sensor array toward a center of the support structure to center the left camera lens substantially on a scene center or principal point.
