Abstract: Methods and systems for reductions in switching between depth planes of a multi-depth plane display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. The system may monitor the fixation points based upon the gaze of each of the user's eyes, with each fixation point being a three-dimensional location in the user's field of view. Location information of virtual objects to be presented to the user are obtained, with each virtual object being associated with a depth plane. In some embodiments, the depth plane on which the virtual object is to be presented is modified based upon the fixation point of the user's eyes. For example, where the user is switching their fixation between virtual objects on two different depth planes, the display system may be configured to modify the presentation of one of the objects such that both objects are placed on the same depth plane.

Abstract: An augmented reality display system is configured to use fiducial markers to align 3D content with real objects. The augmented reality display system can optionally include a depth sensor configured to detect a location of a real object. The augmented reality display system can also include a light source configured to illuminate at least a portion of the object with invisible light, and a light sensor configured to form an image using reflected portion of the invisible light. Processing circuitry of the display system can identify a location marker based on the difference between the emitted light and the reflected light and determine an orientation of the real object based on the location of the real object and a location of the location marker.

Abstract: In some embodiments, a display system comprising a head-mountable, augmented reality display is configured to perform a neurological analysis and to provide a perception aid based on an environmental trigger associated with the neurological condition. Performing the neurological analysis may include determining a reaction to a stimulus by receiving data from the one or more inwardly-directed sensors; and identifying a neurological condition associated with the reaction. In some embodiments, the perception aid may include a reminder, an alert, or virtual content that changes a property, e.g. a color, of a real object. The augmented reality display may be configured to display virtual content by outputting light with variable wavefront divergence, and to provide an accommodation-vergence mismatch of less than 0.5 diopters, including less than 0.25 diopters.
