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: 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: 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: 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: A wearable display system can automatically recognize a physical remote or a device that the remote serves using computer vision techniques. The wearable system can generate a virtual remote with a virtual control panel viewable and interactable by user of the wearable system. The virtual remote can emulate the functionality of the physical remote. The user can select a virtual remote for interaction, for example, by looking or pointing at the parent device or its remote control, or by selecting from a menu of known devices. The virtual remote may include a virtual button, which is associated with a volume in the physical space. The wearable system can detect that a virtual button is actuated by determining whether a portion of the user's body (e.g., the user's finger) has penetrated the volume associated with the virtual button.

Abstract: Systems and methods for iris authentication are disclosed. In one aspect, a deep neural network (DNN) with a triplet network architecture can be trained to learn an embedding (e.g., another DNN) that maps from the higher dimensional eye image space to a lower dimensional embedding space. The DNN can be trained with segmented iris images or images of the periocular region of the eye (including the eye and portions around the eye such as eyelids, eyebrows, eyelashes, and skin surrounding the eye). With the triplet network architecture, an embedding space representation (ESR) of a person's eye image can be closer to the ESRs of the person's other eye images than it is to the ESR of another person's eye image. In another aspect, to authenticate a user as an authorized user, an ESR of the user's eye image can be sufficiently close to an ESR of the authorized user's eye image.

Abstract: A wearable device can include an inward-facing imaging system configured to acquire images of a user's periocular region. The wearable device can determine a relative position between the wearable device and the user's face based on the images acquired by the inward-facing imaging system. The relative position may be used to determine whether the user is wearing the wearable device, whether the wearable device fits the user, or whether an adjustment to a rendering location of virtual object should be made to compensate for a deviation of the wearable device from its normal resting position.

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: 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.
