Abstract: Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). An inter-pupillary distance (IPD) value is determined from a signal from a position sensitive device coupled to two moveable sighting fixtures mounted to a head mounted display (HMD) having two fixed optics configured for a specific inter-pupillary distance. The position sensitive device is configured to produce a signal that corresponds to a distance between the two sighting fixtures. The images are warped with a processor to optimize display of the images with the two fixed optics for the determined IPD value.

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: A spectator of a computer simulation who is not playing the computer simulation and is associated with a spectator device for viewing the simulation without controlling it is identified. An indication can be received from the spectator that a portion of the computer simulation contains an error. The indication is transmitted to a computer network, from whence is received a corrected version of the computer simulation that does not contain the error. The corrected version of the computer simulation can then be presented. The spectator may be awarded for reporting the error.

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: To derive three dimensional (3D) position and orientation of a 3-axis (or more) magnetometer/accelerometer device (such as may be implemented in VR or AR headset or computer game controller) without line of sight constraints, a spinning magnetic field is used to discriminate and remove the external (Earth's) magnetic field from the spinning magnetic field. This reduces the problem to finding the distance to the source of the magnetic field using a calibration table (or formula), finding two angles describing the deviation of the magnetic sensor from the axis of rotation of the spinning magnetic field and the phase around this axis, and from these values deriving the orientation of the sensor.

Abstract: A volume holographic film (such as a photopolymer) that is pre-recorded with patterns subsequently is used to encode LED or low-power laser light reflections from an eye into a binary pattern that can be read at very high speeds by a relatively simple complementary metal-oxide-semiconductor (CMOS) sensor that may be similar to a high framerate, low resolution mouse sensor. The low-resolution mono images from the film are translated into eye poses using, for instance, a look up table that correlates binary patterns to X, Y positions or using a pre-trained convolutional neural network to robustly interpret many variations of the binary patterns for conversion to X, Y positions.

Abstract: Methods and systems for using a position of a mobile device with an integrated display as an input to a video game or other presentation are presented. Embodiments include rendering an avatar on a mobile device such that it appears to overlay a competing user in the real world. Using the mobile device's position, view direction, and the other user's mobile device position, an avatar (or vehicle, etc.) is depicted at an apparently inertially stabilized location of the other user's mobile device or body. Some embodiments may estimate the other user's head and body positions and angles and reflect them in the avatar's gestures.

Abstract: Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). Software-generated calibration images may be presented on a display having two optics. One or more settings for presentation of the calibration image are adjusted. The settings are related to an inter-pupillary distance (IPD) of the user. An input is received from a user when the user perceives the calibration image to be acceptable at a particular value of the one or more settings. An IPD value that corresponds to the particular value of the one or more settings is then determined. The determined IPD value is used in presenting subsequent software-generated images with the stereoscopic display.
