Abstract: Controller visualization systems and methods for use in virtual/augmented reality environments such as walk-around virtual reality environments are described. The virtual representation of a physical control device may be altered based on the context of the virtual environment. Certain embodiments combine the virtual rendering of the tracked control device with a real-time video representation of part of the operating space. In certain embodiments, the display of additional information relating to the function of interactive elements may be displayed based on context, such as when a specific action is required from a user in the virtual space.

Abstract: Methods and systems relating generally to information displays, and more particularly to systems and methods for setting or dynamically adjusting the illumination pulses of a display or portions of a display on an individual color channel (typically R, G, B) basis. The illumination pulses may be adjusted for a plurality of frames at once, or on a frame by frame basis. The illumination pulses may be controlled for an entire image frame, or the illumination pulse may be controlled on a finer basis, for instance on separate areas or sub-regions of a display. Such adjustments can lead to improved sharpness, brightness, or useable lifetime of the display, and can eliminate or reduce discrepancies of visual artifacts in the visual field by providing separate or variable duty cycle capability on an individual color channel basis to the display for use in combination with display images, particularly for use with close-eye display orientations such as those used in augmented reality or virtual reality applications.

Abstract: Methods and systems are disclosed for measuring pixel-by-pixel luminosity and/or chrominance variations on a display, encoding and/or storing the measurements as a set of global and/or pixel-by-pixel correction factors, and/or digitally manipulating imagery with the inverse effect as the measured variations, such that the appearance of visual artifacts caused by the variations is reduced. These methods and systems may be used, for example, as part of the production process for virtual reality headsets, as well as in other applications that make high-fidelity use of displays exhibiting such artifacts (e.g., cell phones, watches, augmented reality displays, and the like).

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 contains 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.

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.
