    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 at least partial support of the optics block.

    Abstract: A method for implementing a graphics pipeline. The method includes building a first shadow map of high resolution, and building a second shadow map based on the first shadow map of lower resolution. The method includes determining a light source affecting a virtual scene, and projecting geometries of objects of an image of the virtual scene onto a plurality of pixels of a display from a first point-of-view. The method includes determining a foveal region when rendering the image, wherein the foveal region corresponds to where an attention of a user is directed. The method includes determining a first set of geometries is drawn to a first pixel, determining the first set of geometries is in shadow based on the light source, and determining the first set of geometries is outside of the foveal region. The method includes rendering the first set of geometries using the second shadow map.

    Abstract: Methods, systems, and computer programs are presented for rendering images on a head mounted display (HMD). One method includes operations for tracking, with one or more first cameras inside the HMD, the gaze of a user and for tracking motion of the HMD. The motion of the HMD is tracked by analyzing images of the HMD taken with a second camera that is not in the HMD. Further, the method includes an operation for predicting the motion of the gaze of the user based on the gaze and the motion of the HMD. Rendering policies for a plurality of regions, defined on a view rendered by the HMD, are determined based on the predicted motion of the gaze. The images are rendered on the view based on the rendering policies.

    Abstract: Methods and systems for presenting an object on to 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: A system for performing a pinch and hold gesture is described. The system includes a head-mounted display (HMD) and a glove, which is worn by a hand of the user. Each finger segment of the glove includes a sensor for detecting positions of the finger segment when moved by the hand. The system includes a computing device interfaced with the HMD and the glove. The computing device analyzes data from the sensors of the finger segments to determine that a pinch and hold gesture is performed by at least two of the finger segments. Moreover, the computing device generates image data that is communicated to the HMD, such that a scene rendered on the HMD is modified to render a visual cue indicative of a location in the scene at which the pinch and hold gesture is associated.
