International Classification:

G06F 7/00
G06F 17/30

US Classification:

707796, 709219

Abstract:

Processing a scenegraph for a client, including: creating a stack of filters, wherein each filter of the stack of filters is configured to edit or create a property on an object within the scenegraph; presenting a query by the client to the stack of filters for a first property on a first object within the scenegraph to determine whether a filter of the stack of filters edits or creates the first property on the first object; and returning a value for the first property if the filter of the stack of filters edits or creates the first property.

Jeremy Selan - Santa Monica CA, US

International Classification:

H04N001/60

US Classification:

Abstract:

Perceptually correctly rendering a color-matched image of a digital imagery including receiving and storing a digital data set representing the digital imagery; computing a three-dimensional lookup table (3-D LUT) using a color transform stack; simulating a real-time film-appearance using the computed 3-D LUT mapped on a graphics card; projecting a first image generated by the graphics card; comparing the first image with a second image generated by a film negative of the digital imagery; and repeating the computing, the simulating, the projecting, and the comparing when the first image is not perceptually substantially similar to the second image.

International Classification:

G01S 7/481
G01S 7/4912

Abstract:

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.

International Classification:

H04N 13/327

H04N 13/371

Abstract:

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.

International Classification:

G06F 3/01
H04N 13/332
G02B 27/01

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.

International Classification:

G06F 3/01
G09G 3/22

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.
