Abstract: This document relates to an optical device that uses adaptive optics as part of an optical system. The adaptive optics can be used to correct light rays that correspond to a portion of an eye box based on information received from an eye-tracking unit, and can also correct for aberrations in the optics in the optical device. The adaptive optics include corrective elements that can be modified using modifying elements to correct the angle of light rays, such that rays associated with a specific pupil position and gaze direction of a user's eye can be made parallel and ensure a high quality image is viewed by the user.

Abstract: This document relates to head mounted display devices. In one example the head mounted display device includes a light engine including an array of individually controllable pixels that can be energized to emit light. The example also includes an optical assembly physically aligned with the light engine and including a set of focusing elements facing toward the light engine and a different set of focusing elements facing away from the light engine.

Abstract: A head-mounted, near-eye display device includes a central display and a peripheral display. The central display creates a central image of a first resolution in a central eyebox. The peripheral display creates a peripheral image of a second resolution, lower than the first resolution, in a peripheral eyebox, different than the central eyebox.

Abstract: Techniques for implementing eye tracking using various real-time computational solutions to a three-dimensional eye tracking framework. An exemplary eye tracking system for a NED device includes sensors that are directed toward and angularly offset from a user's eyes in a manner that causes circular features (e.g., irises and/or pupils) of the user's eyes to appear elliptical within sensor planes of the individual sensors. An iris and/or pupil of an eye will appear circular when the eye is looked at straight on (i.e., perpendicular to an optical axis of the eye's lens) but elliptical when observed from an angular offset. The eye tracking systems and methods disclosed herein exploit these principles to track movements of the user's eyes with a higher degree of accuracy than conventional eye tracking systems.

Abstract: Technologies for performing user-specific calibration of eye tracking systems for Near-Eye-Display (NED) devices. The NED device may sequentially present different virtual stimuli to a user while concurrently capturing instances of eye tracking data. The eye tracking data reveals calibration ellipse centers that uniquely correspond to individual virtual stimuli. The calibration ellipse centers may be used define a polygon grid in association with a sensor plane. The resulting polygon grid is used during operation to interpolate the real-time gaze direction of the user. For example, a real-time instance of eye tracking data may be analyzed to determine which particular polygon of the polygon grid a real-time ellipse center falls within. Then, distances between the real-time ellipse center and the vertices of the particular polygon may be determined. A proportionality factor is then determined based on these distances and is used to interpolate the real-time eye gaze of the user.

Abstract: A near-eye display system comprises a display projector configured to emit display light, an optical waveguide, a fixed-focus lens, and a variable-focus lens of variable optical power. The optical waveguide is configured to receive the display light and to release the display light toward an observer. The fixed-focus lens is arranged to adjust a vergence of the display light released from the optical waveguide. The variable-focus lens is arranged in series with the fixed-focus lens and configured to vary, responsive to a focusing bias, the vergence of the display light released from the optical waveguide.

Abstract: An eye tracking system for a NED device includes sensors that are directed toward and angularly offset from a user's eyes in a manner that causes circular features (e.g., irises and/or pupils) of the user's eyes to appear elliptical within sensor planes that correspond to the individual sensors. The eye tracking system determines parameters associated with detected ellipses and then uses these parameters to generate 3D propagations from the detected ellipses back to the user's eyes. By analyzing these 3D propagations with respect to ocular rotation models that represent how the pupils and iris rotate about the center of the eye, the eye tracking system determines pupil orientation parameters that define physical characteristics of the user's eyes. The pupil orientation parameters may then be used to determine interpupillary distance and/or vergence of the user's visual axis that extend from the user's fovea.

Abstract: Examples are disclosed that relate to the securing of a distributed sensor system. One example provides a security component configured to be communicatively coupled between a trusted element and a distributed sensor system. The security component includes a configuration table configured to store sensor configurations for the distributed sensor system, and a security controller configured to secure the configuration table by limiting access to the configuration table according to a selected security protocol. The security component further includes a feedback controller configured to receive signals from the distributed sensor system and send feedback instructions to the trusted element based at least on a comparison of the signals received from the distributed sensor system with values in the configuration table.

Abstract: Examples are disclosed that relate to the securing of a distributed sensor system. One example provides a security component configured to be communicatively coupled between a trusted element and a distributed sensor system. The security component includes a secured controller configured to receive a signal for forwarding to a sensor of the distributed sensor system, authenticate the signal as being sent from the trusted element, and forward the authenticated signal to the sensor. Further, when the signal is not authenticated as being sent from the trusted element, the secured controller may be configured to not forward the signal to the sensor. The security component also includes a feedback controller configured to analyze signals received from the distributed sensor system and send one or more feedback instructions to the trusted element based at least on the signals from the distributed sensor system.
