    Abstract: An apparatus is disclosed for capturing image information. The apparatus includes a waveguide having opposed planar input and output faces. A diffractive optical element (DOE) is formed across the waveguide. The DOE is configured to couple a portion of the light passing through the waveguide into the waveguide. The light coupled into the waveguide is directed via total internal reflection to an exit location on the waveguide. The apparatus further includes a light sensor having an input positioned adjacent the exit location of the waveguide to capture light exiting therefrom and generate output signals corresponding thereto. A processor determines the angle and position of the coupled light with respect to the input face of the waveguide based on the output signals.

    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.

    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 pose of the eye in the eye image is determined. From the eye pose, an eyelid shape (of an upper eyelid or a lower eyelid) can be estimated using an eyelid shape mapping model. The eyelid shape mapping model relates the eye pose and the eyelid shape. In another aspect, the eyelid shape mapping model is learned (e.g., using a neural network).

    Abstract: Disclosed herein is an augmented reality (AR) system that provides information about purchasing alternatives to a user who is about to purchase an item or product (e.g., a target product) in a physical retail location. In some variations, offers to purchase the product and/or an alternative product are provided by the merchant and/or competitors via the AR system. An offer negotiation server (ONS) aggregates offer data provided various external parties (EPs) and displays these offers to the user as the user is considering the purchase of a target product. In some variations, an AR system may be configured to facilitate the process of purchasing items at a retail location.

    Abstract: A wearable display system includes a mixed reality display for presenting a virtual image to a user, an outward-facing imaging system configured to image an environment of the user, and a hardware processor operably coupled to the mixed reality display and to the imaging system. The hardware processor is programmed to generate a virtual remote associated with a parent device, render the virtual remote and the virtual control element on the mixed reality display, determine when the user of the wearable system interacts with the virtual control element of the virtual remote, and perform certain functions in response to user interaction with a virtual control element of the virtual remote. These functions may include generation the virtual control element to move on the mixed reality display; and when movement of the virtual control element surpasses a threshold condition, generate a focus indicator for the virtual control element.

    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).
