Abstract: Augmented reality systems and methods for user health analysis. Methods for user health analysis may include collecting data for an initial prediction model and continuing to collect additional data based on one or more data criteria. The methods may further include updating the initial prediction model based on the additional data to produce a revised prediction model or causing an intervention to occur based on the additional data. The data may be collected by a display system including one or more sensors configured to collect user-specific data and a display device configured to present virtual content to a user. The display device may be configured to output light with variable wavefront divergence.

Abstract: A display system includes a wearable display device for displaying augmented reality content. The display device comprises a display area comprising light redirecting features that are configured to direct light to a user. The display area is at least partially transparent and is configured to provide a view of an ambient environment through the display area. The display device is configured to determine that a reflection of the user is within the user's field of view through the display area. After making this determination, augmented reality content is displayed in the display area with the augmented reality content augmenting the user's view of the reflection. In some embodiments, the augmented reality content may overlie on the user's view of the reflection, thereby allowing all or portions of the reflection to appear to be modified to provide a realistic view of the user with various modifications made to their appearance.

Abstract: Various embodiments of a user-wearable device can comprise a frame configured to mount on a user. The device can include a display attached to the frame and configured to direct virtual images to an eye of the user. The device can also include a light source configured to provide polarized light to the eye of the user and that the polarized light is configured to reflect from the eye of the user. The device can further include a light analyzer configured to determine a polarization angle rotation of the reflected light from the eye of the user such that a glucose level of the user can be determined based at least in part on the polarization angle rotation of the reflected light.

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.

Abstract: Wearable spectroscopy systems and methods for identifying one or more characteristics of a target object are described. Spectroscopy systems may include a light source configured to emit light in an irradiated field of view and an electromagnetic radiation detector configured to receive reflected light from a target object irradiated by the light source. One or more processors of the systems may identify a characteristic of the target object based on a determined level of light absorption by the target object. Some systems and methods may include one or more corrections for scattered and/or ambient light such as applying an ambient light correction, passing the reflected light through an anti-scatter grid, or using a time-dependent variation in the emitted light.

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: A wearable ophthalmic device is disclosed. The device may include a head-mounted light field display configured to generate a physical light field comprising a beam of light. The head-mounted light field display may direct the beam of light into a user's eye, thereby producing a retinal reflex. The device may also include a head-mounted photodetector array configured to receive the retinal reflex and to generate numerical image data. The device may also include a light field processor configured to control the light field display, to analyze the retinal reflex using the numerical image data, and to determine an optical prescription for the user's eye based on the analysis of the retinal reflex.

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.
