Patent number: 11500607Abstract: The disclosure relates generally to techniques for determining pupil location of a display device's user via imaging sensors on the display device, and using that information to verify and/or correct positioning of the display device or its internal components. The display device may be a head-mounted display (“HMD”) device with display panels separated from a wearer's eyes via intervening lenses, with the sensors including optical flow sensor integrated circuits mounted on or near at least one of the display panels to capture images of the wearer's eye locations through the lenses, and with the correction to the positioning including modifications to the alignment or other positioning of the HMD device on the wearer user's head and/or its internal components within the HMD device (e.g., based on automated control of motors on the HMD device) to reflect a target alignment of the wearer's eyes relative to displayed information.Type: GrantFiled: July 21, 2021Date of Patent: November 15, 2022Assignee: Valve CorporationInventors: Joshua Mark Hudman, Jeremy Adam Selan

Publication number: 20220308167Abstract: Optical positional tracking systems that may be used in virtual reality (VR)/augmented reality (AR) applications are described. Exemplary implementations comprise one or more receivers and one or more transmitters. Exemplary transmitters contain two orthogonal rotors that each emit a fan-shaped laser beam. Each beam is swept as the rotors are spun at constant speed. Exemplary optical receivers can be relatively small, and mounted at convenient locations on the VR display. These receivers consist of small optical detectors that may be mounted on head-mounted VR displays. Exemplary systems determine position by measuring the time at which each swept beam crosses each receiver/detector.Type: ApplicationFiled: June 13, 2022Publication date: September 29, 2022Inventors: Alan Yates, Jeremy Adam Selan

Patent number: 11343486Abstract: A head-mounted display (HMD) system may include a HMD with a housing and a pair of display panels, mounted within the housing, that are counterrotated in orientation. A compositor of the HMD system may also be configured to provide camera pose data with counterrotated camera orientations to an executing application (e.g., a video game application), and to resample the frames received from the application, with or without rotational adjustments in the clockwise and counterclockwise directions depending on whether the display panels of the HMD are upright-oriented or counterrotated in orientation. A combined approach may use the counterrotated camera orientations in combination with counterrotated display panels to provide a HMD with optimized display performance.Type: GrantFiled: January 13, 2021Date of Patent: May 24, 2022Assignee: Valve CorporationInventor: Jeremy Adam Selan

Patent number: 11314322Abstract: 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.Type: GrantFiled: November 16, 2020Date of Patent: April 26, 2022Assignee: Valve CorporationInventor: Jeremy Adam Selan

Patent number: 11056042Abstract: Systems and methods for providing display panels with reduced visual artifacts. A display system is provided that includes a pixel array having a plurality of pixels arranged in rows and columns. The display system receives an image stream that includes a plurality of sets of image data that each represent an image to be sequentially presented by the display system. The data for each frame or set of image data is loaded into the pixel array according to a loading sequence with reduces the visual artifacts perceived by a viewer of the display system. The loading sequence may include an inside-out loading sequence which gives preference to a central region of the pixel array, a speculative preloading sequence which first loads portions of the pixel array with speculative data, or various combinations thereof.Type: GrantFiled: March 24, 2020Date of Patent: July 6, 2021Assignee: Valve CorporationInventors: Jeremy Adam Selan, Duane Martin Evans

Patent number: 10802287Abstract: 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.Type: GrantFiled: March 27, 2019Date of Patent: October 13, 2020Assignee: Valve CorporationInventor: Jeremy Adam Selan
