    Abstract: Method for creating marker-based shared augmented reality (AR) session starts with initializing a shared AR session by a first device and by a second device. The first device displays on a display a marker. The second device detects the marker using a camera included in the second device and captures an image of the marker using the camera. The second device determines a transformation between the first device and the second device using the image of the marker. A common coordinate frame is then determined using the transformation, the shared AR session is generated using the common coordinate frame, and the shared AR session is caused to be displayed by the first device and by the second device. Other embodiments are described herein.

    Abstract: Example embodiments described herein therefore relate to an AR guidance system to perform operations that include: detecting a client device at a location within a geo-fenced area, wherein the geo-fenced area may include within it, a destination of interest; determining a route to the destination of interest from the location of the client device within the geo-fenced area; causing display of a presentation of an environment within an AR interface at the client device; detecting a display of real-world signage within the presentation of the environment; generating a media item in response to the detecting the display of the signage within the presentation of the environment, wherein the media item is based on the route to the destination of interest; and causing display of the media item within the AR interface based on the position of the signage within the presentation of the environment.

    Abstract: Method of creating shared AR session based on a gesture starts with server receiving observed motion data from first device associated with first user. First device generating observed motion data based on an analysis of data stream comprising images of second user performing a gesture. Second user being associated with second device. Server receiving from second device captured motion data that corresponds to the gesture. Captured motion data being recorded by a sensor included in second device. Server determines whether there is a match between observed motion data from first device and captured motion data from second device. In response to determining that there is the match, server generates shared AR session between first device and second device and causes shared AR session to be displayed by first device and second device. Other embodiments are described herein.

    Abstract: A crowd-sourced modeling system to perform operations that include: receiving image data that comprises image attributes; accessing a 3D model based on at least the image attributes of the image data, wherein the 3D model comprises a plurality of parts that collectively depict an object or environment; identifying a change in the object or environment based on a comparison of the image data with the plurality of parts of the 3D model, the change corresponding to a part of the 3D model from among the plurality of parts; and generating an update to the part of the 3D model based on the image attributes of the image data.

    Abstract: An augmented reality system to generate and cause display of a presentation of a space at a first client device, receive one or more selections of points within the presentation of the space at the first client device, and render graphical elements at the one or more points within the presentation of the space at the first client device. The augmented reality system is further configured to receive a display request to display the space at a second client device, and in response, may render a second presentation of the space at the second client device, wherein the second presentation of the space includes the graphical elements at the one or more points.
