    Abstract: Various implementations disclosed herein include devices, systems, and methods that uses object relationships represented in the scene graph to adjust the position of objects. For example, an example process may include obtaining a three-dimensional (3D) representation of a physical environment that was generated based on sensor data obtained during a scanning process, detecting positions of a set of objects in the physical environment based on the 3D representation, generating a scene graph for the 3D representation of the physical environment based on the detected positions of the set of objects, wherein the scene graph represents the set of objects and relationships between the objects, and determining a refined 3D representation of the physical environment by refining the position of at least one object in the set of objects based on the scene graph and an alignment rule associated with a relationship in the scene graph.

    Abstract: In one implementation, consumption of media content (such as video, audio, or text) is supplemented with an immersive synthesized reality (SR) map based on the media content. In various implementations described herein, the SR map includes a plurality of SR environment representations which, when selected by a user, cause display of a corresponding SR environment.

    Abstract: In one implementation, a method of generating a plane hypothesis is performed by a head-mounted device (HMD) including one or more processors, non-transitory memory, and a scene camera. The method includes obtaining an image of a scene including a plurality of pixels. The method include obtaining a point cloud based on the image of the scene and generating an object classification set based on the image of the scene, each element of the object classification set including a respective plurality of pixels classified as a respective object in the scene. The method includes generating a plane hypothesis based on the point cloud and the object classification set.

    Abstract: In an exemplary process for providing content in an augmented reality environment, image data correspond to a physical environment are obtained. Based on the image data, predefined entities of the plurality of predefined entities in the physical environment are identified using classifiers corresponding to predefined entities. Based on the one or more of the identified predefined entities, a geometric layout of the physical environment is determined. Based on the geometric layout, an area corresponding to a particular entity is determined. The particular entity corresponds to one or more identified predefined entities. Based on the area corresponding to the particular entity, the particular entity in the physical environment is identified using classifiers corresponding to the determined area. Based on the identified particular entity, a type of the physical environment is determined. Based on the type of the physical environment, virtual-reality objects are displayed corresponding to a representation of the physical environment.
