Abstract: Eyewear providing an interactive augmented reality experience between two eyewear devices by using alignment between respective 6DOF trajectories, also referred to herein as ego motion alignment. An eyewear device of user A and an eyewear device of user B track the eyewear device of the other user, or an object of the other user, such as on the user's face, to provide the collaborative AR experience. This enables sharing common three-dimensional content between multiple eyewear users without using or aligning the eyewear devices to common image content such as a marker, which is a more lightweight solution with reduced computational burden on a processor. An inertial measurement unit may also be used to align the eyewear devices.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for continuous surface and depth estimation. A continuous surface and depth estimation system determines the depth and surface normal of physical objects by using stereo vision limited within a predetermined window.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for varied depth determination using stereo vision and phase detection auto focus (PDAF). Computer stereo vision (stereo vision) is used to extract three-dimensional information from digital images. To utilize stereo vison, two optical sensors are displaced horizontally from one another and used to capture images depicting two differing views of a real-world environment from two different vantage points. The relative depth of the objects captured in the images is determined using triangulation by comparing the relative positions of the objects in the two images. For example, the relative positions of matching objects (e.g., features) identified in the captured images are used along with the known orientation of the optical sensors (e.g., distance between the optical sensors, vantage points the optical sensors) to estimate the depth of the objects.

Abstract: Visual-inertial tracking of an eyewear device using a rolling shutter camera(s). The device includes a position determining system. Visual-inertial tracking is implemented by sensing motion of the device. An initial pose is obtained for a rolling shutter camera and an image of an environment is captured. The image includes feature points captured at a particular capture time. A number of poses for the rolling shutter camera is computed based on the initial pose and sensed movement of the device. The number of computed poses is responsive to the sensed movement of the mobile device. A computed pose is selected for each feature point in the image by matching the particular capture time for the feature point to the particular computed time for the computed pose. The position of the mobile device is determined within the environment using the feature points and the selected computed poses for the feature points.

Abstract: An eyewear device with flexible frame for Augmented Reality (AR) is disclosed. At least two sensors and a display are mounted on the flexible frame.

A modeling module is provided to model the real time geometry of the eyewear device on the fly using sensor information of the at least two sensors. The modeled real time geometry is then provided to a rendering module to accurately display the AR to the user.

Abstract: The present disclosure is directed toward systems and methods that provide users with efficient and effective user experiences when browsing, selecting, or inspecting content items. More specifically, systems and methods described herein provide users the ability to easily and effectively select multiple content items via a single touch gesture (e.g., swipe gesture). Additionally, systems and methods disclosed herein can allow users to select various content items in a selection interface, preview a content item, and return to the selection interface with the previous selections remaining intact. Still further, systems and methods described herein allow users to transition between a content graphical user interface and a selection interface based on touch gestures with content items. Embodiments of the present invention further provide improved navigability by collapsing views of content items.

Abstract: The present technology pertains to synchronized video viewing that is supported by the use of a pending changes count to keep the client devices in synchronization while providing a user experience that matches the expectations of the user. A second client device can receive input to change some aspect of the playback of a video that is being viewed synchronously with at least one other device. The second client device can process the event so the video can reflect the received input. The second client device can also send a collaboration message to a synchronized video viewing service to inform other client devices of the command. Since the second client device is aware of its own event, the second client device can ignore processing any other collaboration messages until it receives the collaboration message it initiated echoed back to it. Thereafter it can resume processing received collaboration messages.

Abstract: A spacing fastener comprises a head and a shaft adjoining the head and ending with a tip. The shaft comprises an anchoring screw thread, an under-head screw thread closest to and ending near the head, and a non-threaded shaft portion therebetween. A support element at a distance circumferentially from the screw-thread end of under-head screw thread forms contact point (Au) therewith. In the region overlapping with under-head screw thread in top view, the support element is spaced apart therefrom and forms a contact point (As) for an outer shell lying between the head and under-head screw thread. The distance of contact point (As) from the head is greater than or equal to difference between the distance of contact point (Au) from the head and a tolerance distance of at most 15% of the major diameter of the under-head screw thread. The support element extends lengthwise over less than 150°.
