    Abstract: Methods and systems are provided for using temporal supersampling to increase a displayed resolution associated with peripheral region of a foveated rendering view. A method for enabling reconstitution of higher resolution pixels from a low resolution sampling region for fragment data is provided. The method includes an operation for receiving a fragment from a rasterizer of a GPU and for applying temporal supersampling to the fragment with the low resolution sampling region over a plurality of prior frames to obtain a plurality of color values. The method further includes an operation for reconstituting a plurality of high resolution pixels in a buffer that is based on the plurality of color values obtained via the temporal supersampling. Moreover, the method includes an operation for sending the plurality of high resolution pixels for display.

    Abstract: Methods and systems for presenting an object on a screen of a head mounted display (HMD) include receiving an image of a real-world environment in proximity of a user wearing the HMD. The image is received from one or more forward facing cameras of the HMD and processed for rendering on a screen of the HMD by a processor within the HMD. A gaze direction of the user wearing the HMD, is detected using one or more gaze detecting cameras of the HMD that are directed toward one or each eye of the user. Images captured by the forward facing cameras are analyzed to identify an object captured in the real-world environment that is in line with the gaze direction of the user, wherein the image of the object is rendered at a first virtual distance that causes the object to appear out-of-focus when presented to the user. A signal is generated to adjust a zoom factor for lens of the one or more forward facing cameras so as to cause the object to be brought into focus. The adjustment of the zoom factor causes the image of the object to be presented on the screen of the HMD at a second virtual distance that allows the object to be discernible by the user.

    Abstract: Gaze tracking data representing a user's gaze is analyzed to determine one or more regions of interest. One or more gaze tracking error parameters are determined from the gaze tracking data including a rate of rotation of a user's eye with respect to one or more axes. An error in a fixation of the user's eye on a particular region of interest is determined. Adjusted foveation data is determined representing an adjusted size and/or shape of one or more regions of interest in one or more images to be subsequently presented to the user based on the one or more gaze tracking parameters. The compression of the one or more transmitted images is adjusted so that fewer bits are needed to transmit data for portions of an image outside the one or more regions of interest than for portions of the image within the one or more regions of interest

    Abstract: A method for implementing a graphics pipeline. The method includes determining a plurality of light sources affecting a virtual scene. Geometries of objects of an image of the scene is projected onto a plurality of pixels of a display from a first point-of-view. The pixels are partitioned into a plurality of tiles. A foveal region of highest resolution is defined for the image as displayed, wherein a first subset of pixels is assigned to the foveal region, and wherein a second subset of pixels is assigned to a peripheral region that is outside of the foveal region. A first set of light sources is determined from the plurality of light sources that affect one or more objects displayed in a first tile that is in the peripheral region. At least two light sources from the first set is clustered into a first aggregated light source affecting the first tile when rendering the image in pixels of the first tile.

    Abstract: A head mounted display is provided. The head mounted display includes an optics block having a display screen. The optics block has a forward-facing region, a lower-facing region, a top-facing region, an inside-facing region, and side regions that extend from the forward-facing region toward the inside-facing region. The display screen is viewable from the inside-facing region. A band adjustment unit is located opposite the optics block. A headband has a front portion and an adjustable portion. The adjustable portion of the headband is connected to the band adjustment unit to contract a size of the headband or expand the size of the headband. The front portion of the headband has a connection to the top-facing region of the optics block that is proximate to the inside-facing region. A pad is disposed inside of the front portion of the headband. The pad provides for at least partial support of the optics block when the head mounted display is worn by a user.
