Automatic field calibration for eye tracking in a head-mounted display is discussed. Processors can be configured to acquire images of a user's eye, estimate gaze direction from these images, and enhance accuracy by applying time-based filtering, such as Kalman filtering, across multiple images. Refined gaze estimates enable prediction of future gaze direction, facilitating dynamic rendering of images within the display. Calibration precision can be further improved by utilizing head rotation data, statistical analysis of sequential eye images, and/or user interactions, including interface selections, controller movements, or hand gestures. Confidence metrics can be generated for each gaze estimation, and calibration parameters are updated (e.g., continuously) for each user during ongoing use, reducing or eliminating the need for explicit calibration procedures. Predictive gaze estimation can contribute to both advanced eye-tracking modeling and optimization of rendered content, delivering adaptive calibration and enhanced real-time user experience.
Light from a display device is optically shifted to increase an effective resolution of the display device and/or to decrease pixel structure artifacts. Without limitation, optical shifting can be performed using a birefringent element or an element with a varying refractive index. The optical shifter can electronically controlled to toggle between shifting light and letting light pass through the optical shifter without being shifted.

Systems and methods for a cost-effective, high-performance optical lens for head mounted displays (HMDs) or other applications. The lens assembly combines a thin lens with microfeatures on at least one transmission surface, and a thicker lens with a curved surface, allowing for plano-convex or bi-convex configurations. Both lenses have mounting areas with complementary microfeatures on their peripheries, facilitating their coupling and self-alignment within low tolerances. These microfeatures, including the mounting ones, can be generated using a high-precision process like diamond turning, thereby ensuring precision in alignment and function.
Client machines running game executables of a video game(s) may utilize a file system proxy component that is configured to track read operations made by the game executable during a game session, to generate access data based on the tracked read operations, and to report the access data to a remote system. This telemetry approach allows the remote system to collect access data reported by multiple client machines, to catalogue the access data according to client system configuration, and to analyze the access data to generate data that is usable by client machines to implement various game-related features including, without limitation, “instant play” of video games, discarding of unused blocks of game data to free up local memory resources, and/or local prefetching of game data for reducing latency during gameplay.

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.
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 high-attention subregion of the scene. The 2D array of pixels may be encoded using a technique that controls a quality parameter at compression unit granularity, such as macroblock or coding tree unit granularity. At the display device, the encoded pixel data is decoded to obtain the 2D array of pixels for the frame.

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. In some examples, an LCD display device includes several components. Two of the components are the display matrix, which obstructs light in a granular or pixelated fashion to create an image, and a light source or backlight.
Methods and systems relating to a file distribution scheme in a computer network are disclosed that distributes files in an efficient manner that reduces, among other things, network traffic. In an embodiment of the invention, a method for updating a file is disclosed. In such a method, unique chunks in a first version of a digital file are identified. For a second version of the digital file, chunks that are the same as in the first version are identified. Recompilation information is generated and stored for these identified chunks. Also, for the second version of the digital file, chunks in the second version that are different from chunks in the first version are identified. Recompilation information is generated and stored for these identified chunks. With this information, the second version of the digital file is completely defined and can be efficiently stored.
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.

G02F 1/139 - Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulatingNon-linear optics for the control of the intensity, phase, polarisation or colour based on liquid crystals, e.g. single liquid crystal display cells characterised by the electro-optical or magneto-optical effect, e.g. field-induced phase transition, orientation effect, guest-host interaction or dynamic scattering based on orientation effects in which the liquid crystal remains transparent
A handheld video game controller is operable in Bluetooth Low Energy (BLE) mode to allow for sending controller input data to a target BLE device in a manner that bypasses any operating system (OS) restrictions that might otherwise be imposed on game controller input. When operating in the BLE mode, the handheld video game controller pairs (establishes a radio link) with a BLE device executing a client application used for video game streaming. During gameplay, the video game executes on a host computer and the player provides user input to the game controller to control an aspect of the video game. In response to such user input, the game controller sends controller input data to the BLE device via a radio of the game controller. The player may switch between operating the game controller in BLE mode and receiver mode using input gestures on the game controller.
