Abstract: Methods and systems are disclosed relating to a lens system that allows for simultaneous focus of near and far-away images with one pair of glasses, heads-up-displays (HUDs), and the like, without the need to move the user's eyes. This lens system may be used in a HUD application, for example, where the user may focus on a display lens that may be approximately one inch from the eye to view computer-generated information such as altitude, temperature, directions, and the like, and simultaneously view the individual's surroundings. The lens system may include a liquid lens that when modulated may vary from a near-focus state to a far-focus state rapidly by using an electrowetting or piezoelectric hydraulic actuator. This variable rate lens may be multiplexed at a rate that allows both near and far-away images to appear in focus simultaneously through the advantageous use of a user's persistence of vision.

Abstract: Various embodiments are directed towards employing one or more physical sensors arranged on or in proximity to a video game player to obtain biofeedback measures that are then useable to dynamically modify a state of play of a video game. The sensors may be connected or even un-connected to the game player, replace, or otherwise augment traditional physical game controllers. The sensors gather various biofeedback measures and provide such measures to a biofeedback application programming interface (API). Before and/or during video game play, the video game queries the biofeedback API to request inferences about the game player's state of arousal. The response to the query is then used to modify the state of the video game play. Where the video game is a multi-player video game, biofeedback measures from other game players may also be obtained and used to further modify the state of the video game play.

A plurality of tracking sensors is disposed in the tracking arc, and are responsive to electromagnetic radiation emitted by the electronic system. An array of proximity sensors are spatially distributed around the outer surface of the handle portion, and are responsive to a proximity of the user's fingers to the outside surface of the handle portion.

Abstract: The disclosure relates generally to techniques for using information about a user's actual or predicted pupil location for correcting optical distortions that are specific to an optical lens and display assembly through which the user is viewing one or more images. The described techniques may include identifying and mapping optical distortions specific to an optical lens and display assembly, and using such mapped optical distortions to correct images displayed to a wearer or other user receiving images via the assembly, such as based at least in part on pupil location of the wearer or other user. As one example, the one or more optical lens may be mounted inside a head-mounted display (HMD) that also includes a display panel or other image source for an eye of a wearer, and if so one or more pupil tracking mechanisms may be integrated into the HMD.

Abstract: Methods and systems are disclosed for controlling the focus depth of a 2D projected image on a pixel by pixel basis or on a region by region basis to create a 3D projected image that may be used for a heads up display (HUD) for augmented reality applications. The 3D projected image may be overlaid or combined with a 3D real world view using multiple reflective LCD arrays. The multiple reflective LCD arrays may receive a 2D projected image and may generate different length optical paths that may add depth to the 2D projected image to create a 3D projected image. The 3D projected image may be combined with the real world 3D image to create a 3D image encompassing a real world image and a 3D projection image that looks real and contains depth within the image.

Abstract: Optical positional tracking systems that may be used in virtual reality (VR)/augmented reality (AR) applications are described. Exemplary implementations comprise one or more receivers and one or more transmitters. Exemplary transmitters contains two orthogonal rotors that each emit a fan-shaped laser beam. Each beam is swept as the rotors are spun at constant speed. Exemplary optical receivers can be relatively small, and mounted at convenient locations on the VR display. These receivers consist of small optical detectors that may be mounted on head-mounted VR displays. Exemplary systems determine position by measuring the time at which each swept beam crosses each receiver/detector.

Abstract: Various game controller hardware and user interface configurations are disclosed. Some configurations may comprise two circular trackpads, driven by the player's thumbs, which may be clickable, allowing the entire surface to act as a button. Haptic feedback may be based on dual linear resonant actuators (e.g., by means of strong, weighted electro-magnets attached to each of the dual trackpads), capable of delivering a wide range of force and vibration, allowing control over frequency, amplitude, and direction of movement. The haptics-related components in certain implementations may also play audio waveforms and thereby function as speakers. In the center of the controller according to certain configurations may be another touch-enabled surface, this one backed by a display screen. In some configurations this entire screen itself may also be clickable, like a large single button. A variety of other exemplary implementations and configurations are described.

Reconstruction algorithms according to certain embodiments include three stages: (1) hole filling; (2) cross-cell blending; and (3) Gaussian blur.

Abstract: A controller for an electronic system includes a tracking member fixed to a controller body. The controller body has a head that adjoins a handle at a neck region, and that includes at least one thumb-operated control. The controller includes a hand retainer that in a closed position is configured to physically bias the user's palm against an outer surface of the handle. The hand retainer includes a resilient member that biases the hand retainer towards an open position.

The tracking member includes transducers that are coupled to the electronic system by electromagnetic radiation. Proximity sensors, spatially distributed on the handle, are responsive to a proximity of the user's fingers to the outer surface of the handle.

Abstract: Methods and systems are disclosed for measuring pixel-by-pixel luminosity and/or chrominance variations on a display, encoding and/or storing the measurements as a set of global and/or pixel-by-pixel correction factors, and/or digitally manipulating imagery with the inverse effect as the measured variations, such that the appearance of visual artifacts caused by the variations is reduced. These methods and systems may be used, for example, as part of the production process for virtual reality headsets, as well as in other applications that make high-fidelity use of displays exhibiting such artifacts (e.g., cell phones, watches, augmented reality displays, and the like).

Abstract: Methods and systems relating generally to information displays, and more particularly to systems and methods for setting or dynamically adjusting the illumination pulses of a display or portions of a display on an individual color channel (typically R, G, B) basis. The illumination pulses may be adjusted for a plurality of frames at once, or on a frame by frame basis. The illumination pulses may be controlled for an entire image frame, or the illumination pulse may be controlled on a finer basis, for instance on separate areas or sub-regions of a display. Such adjustments can lead to improved sharpness, brightness, or useable lifetime of the display, and can eliminate or reduce discrepancies of visual artifacts in the visual field by providing separate or variable duty cycle capability on an individual color channel basis to the display for use in combination with display images, particularly for use with close-eye display orientations such as those used in augmented reality or virtual reality applications.
