Abstract: Methods and systems are disclosed for performing operations comprising: receiving video that includes a depiction of a real-world object; generating a three-dimensional (3D) body mesh associated with the real-world object that tracks movement of the real-world object across frames of the video; obtaining an external mesh associated with an augmented reality (AR) element; determining that a first portion of the external mesh is associated with movement information of the 3D body mesh; determining that a second portion of the external mesh is associated with movement information of an external force model; deforming the first and second portions of the external mesh separately based on movement information of the 3D body mesh and movement information of the external force model; and modifying the video to include a display of the AR element based on the deformed first and second portions of the external mesh.

Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and a method for detecting a pose of a user. The program and method include operations comprising: receiving a monocular image that includes a depiction of a body of a user in a given pose; detecting a plurality of skeletal joints of the body depicted in the monocular image; generating an outline of the body of the user based on the plurality of skeletal joints; retrieving a mask that represents a target pose; comparing the outline of the body depicted in the monocular image with the mask that represents the target pose; and determining that the given pose of the body of the user matches the target pose in response to comparing the outline of the body with the mask.

Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program, and a method for performing operations comprising: receiving a video that depicts a person; tracking three-dimensional (3D) movement of the person within the video using a 3D reference point; computing a 3D position for placement of an augmented reality item relative to the 3D reference point; causing to be displayed the augmented reality item within the video at the 3D position; and updating the 3D position of the augmented reality item in the video as the 3D reference point changes based on the 3D movement of the person.

Abstract: A virtual wave creation system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the virtual wave creation system to generate, for each of multiple initial depth images, a respective wave image by applying a transformation function that is responsive to a selected input parameter to the initial three-dimensional coordinates. The virtual wave creation system creates a warped wave video including a sequence of the generated warped wave images. The virtual wave creation system presents, via an image display, the warped wave video.

Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and a method for detecting a pose of a user. The program and method include operations comprising receiving a monocular image that includes a depiction of a body of a user; detecting a plurality of skeletal joints of the body based on the monocular image; accessing a video feed comprising a plurality of monocular images received prior to the monocular image; filtering, using the video feed, the plurality of skeletal joints of the body detected based on the monocular image; and determining a pose represented by the body depicted in the monocular image based on the filtered plurality of skeletal joints of the body.

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.
