Abstract: Apparatuses and methods for displaying a 3-D representation of an object are described. Apparatuses can include a rotatable structure, motor, and multiple light field sub-displays disposed on the rotatable structure. The apparatuses can store a light field image to be displayed, the light field image providing multiple different views of the object at different viewing directions. A processor can drive the motor to rotate the rotatable structure and map the light field image to each of the light field sub-displays based in part on the rotation angle, and illuminate the light field sub-displays based in part on the mapped light field image. The apparatuses can include a display panel configured to be viewed from a fiducial viewing direction, where the display panel is curved out of a plane that is perpendicular to the fiducial viewing direction, and a plurality of light field sub-displays disposed on the display panel.

Abstract: Systems and methods for eyelid shape estimation are disclosed. In one aspect, after receiving an eye image of an eye (e.g., from an image capture device), an eye-box is generated over an iris of the eye in the eye image. A plurality of radial lines can be generated from approximately the center of the eye-box to an upper edge or a lower edge of the eye box. Candidate points can be determined to have local maximum derivatives along the plurality of radial lines. From the candidate points, an eyelid shape curve (e.g., for an upper eyelid or a lower eyelid) can be determined by fitting a curve (e.g., a parabola or a polynomial) to the candidate points or a subset of the candidate points.

Abstract: Apparatus and methods for displaying an image by a rotating structure are provided. The rotating structure can comprise blades of a fan. The fan can be a cooling fan for an electronics device such as an augmented reality display. In some embodiments, the rotating structure comprises light sources that emit light to generate the image. The light sources can comprise light-field emitters. In other embodiments, the rotating structure is illuminated by an external (e.g., non-rotating) light source.

Abstract: A display system comprises 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: Examples of an imaging system for use with a head mounted display (HMD) are disclosed. The imaging system can include a forward-facing imaging camera and a surface of a display of the HMD can include an off-axis diffractive optical element (DOE) or hot mirror configured to reflect light to the imaging camera. The DOE or hot mirror can be segmented. The imaging system can be used for eye tracking, biometric identification, multiscopic reconstruction of the three-dimensional shape of the eye, etc.

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 devices for estimating position of a device within a 3D environment are described. Embodiments of the methods include sequentially receiving multiple image segments forming an image representing a field of view (FOV) comprising a portion of the environment. The image includes multiple sparse points that are identifiable based in part on a corresponding subset of image segments of the multiple image segments. The method also includes sequentially identifying one or more sparse points of the multiple sparse points when each subset of image segments corresponding to the one or more sparse points is received and estimating a position of the device in the environment based on the identified the one or more sparse points.
