Abstract: A mat has an embedded array of light sensors under a micro-faceted lens array to provide an array of light intensity values for various incident angles of incident real world light. Virtual objects may be projected onto the mat and, using the information from the light sensors, virtually illuminated to match the real-world lighting environment. A touch sensor array may be embedded in the mat to allow users to interact with the virtual objects and provide other input. The surface of the micro-faceted lens array may be coated with a patterned infrared (IR) reflective coating, such that the mat passively reflects a specific band of IR wavelengths in a pattern to act as a fiducial marker.

Abstract: A mobile device such as a mobile phone is used to image a nearby user for eye tracking at a closer range than would be provided by cameras on a display device such as a TV and send the eye tracking data to a server streaming video being presented on the display. The eye tracking data is used by the server to identify a region of interest (ROI) in the video, which is more highly compressed than regions outside the ROI to facilitate efficient compression of the video game image while preserving the quality of the ROI in the image where the user is looking.

Abstract: In some implementations, a method is provided, including the following operations: receiving, from a controller device, controller input that identifies a pose of a user's hand; determining a degree of similarity of the controller input to a predefined target input; rendering in a virtual space a virtual hand that corresponds to the controller device, wherein when the degree of similarity exceeds a predefined threshold, then the virtual hand is rendered so that a pose of the virtual hand conforms to a predefined hand pose, and wherein when the degree of similarity does not exceed the predefined threshold, then the virtual hand is rendered so that the pose of the virtual hand dynamically changes in response to changes in the controller input.
