    Abstract: Systems and methods for determining movement of a hand-held controller (HHC) with respect to a head-mounted display (HMD) are described. A camera is located at a lower region of the HMD for capturing images of the HHC. The images of the HHC are used to determine a position and an orientation of the HHC with reference to the HMD. Also, the camera or another camera can be used to determine a position and orientation of the HMD with respect to a real-world environment. The position and orientation of the HMD and the position and orientation of the HHC are used to change to state of an application executed on a game cloud.

    Abstract: A method to identify positions of fingers of a hand is described. The method includes capturing images of a first hand using a plurality of cameras that are part of a wearable device. The wearable device is attached to a wrist of a second hand and the plurality of cameras of the wearable device is disposed around the wearable device. The method includes repeating capturing of additional images of the first hand, the images and the additional images captured to produce a stream of captured image data during a session of presenting the virtual environment in a head mounted display (HMD). The method includes sending the stream of captured image data to a computing device that is interfaced with the HMD. The computing device is configured to process the captured image data to identify changes in positions of the fingers of the first hand.

    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 are provided for enabling foveal adaption of temporal anti-aliasing within a foveated rendering presentation. A method for rendering a multi-resolution scene with anti-aliasing within a head mounted display (HMD) is provided. The method includes an operation for rendering a scene that includes a series of video frames. The method also includes operations for applying anti-aliasing to a first region of the scene using a first jitter offset and applying anti-aliasing to a second region of the scene using a second jitter offset. Further, the method provides for generating a foveated scene that includes the first region and the second region and for sending the foveated scene to be displayed on a display associated with the HMD, wherein the first region is associated with a higher resolution than the second scene and the first jitter offset is smaller than the second jitter offset, according to certain embodiments.

    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.
