    Abstract: Systems and methods for synthesizing an image of the face by a head-mounted device (HMD) are disclosed. The HMD may not be able to observe a portion of the face. The systems and methods described herein can generate a mapping from a conformation of the portion of the face that is not imaged to a conformation of the portion of the face observed. The HMD can receive an image of a portion of the face and use the mapping to determine a conformation of the portion of the face that is not observed. The HMD can combine the observed and unobserved portions to synthesize a full face image.

    Abstract: Systems and methods for securely exchanging cryptographically signed records are disclosed. In one aspect, after receiving a content request, a sender device can send a record to a receiver device (e.g., an agent device) making the request. The record can be sent via a short range link in a decentralized (e.g., peer-to-peer) manner while the devices may not be in communication with a centralized processing platform. The record can comprise a sender signature created using the sender device's private key. The receiver device can verify the authenticity of the sender signature using the sender device's public key. After adding a cryptography-based receiver signature, the receiver device can redeem the record with the platform. Upon successful verification of the record, the platform can perform as instructed by a content of the record (e.g., modifying or updating a user account).

    Abstract: A texture projecting light bulb includes an extended light source located within an integrator. The integrator includes at least one aperture configured to allow light to travel out of the interior of the integrator. In various embodiments, the interior of the integrator may be a diffusely reflective surface and the integrator may be configured to produce a uniform light distribution at the aperture to approximate a point source. The integrator may be surrounded by a light bulb enclosure. In various embodiments, the light bulb enclosure may include transparent and opaque regions configured to project a structured pattern of visible and/or infrared light.

    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: Systems and methods for blue light adjustment with a wearable display system are provided. Embodiments of the systems and methods for blue light adjustment can include receiving an initial eye image obtained by an image capture device; adjusting a level of blue light exposed to an eye associated with the initial eye image; receiving an adjustment eye image of the eye exposed to the adjusted level of blue light; detecting a change in a pupillary response of the adjustment eye image relative to the initial eye image; determining that the detected change in the pupillary response passes a biometric application threshold; and utilizing eye images or the detected change in the pupillary response for a biometric application.

    Abstract: Examples of systems and methods for determining a limbic boundary of an iris of an eye are provided. Properties of the corneal bulge can be computed from eye images. An intersection of the corneal bulge with the eye surface (e.g., sclera) can be determined as the limbic boundary. The determined limbic boundary can be used for iris segmentation or biometric applications. A head mounted display can include a camera that images the eye and a processor that analyzes the eye images and determines the limbic boundary.
