Abstract: A method, apparatus and system for facilitating navigation toward a region of interest in an extended scene of video content include determining a timeline including information regarding at least one region of interest in the video content and displaying, in a portion of the video content currently being displayed, a visual indicator indicating a direction in which to move in the video content to cause the display of the at least one region of interest. In one embodiment of the present principles a timeline is attached to the content and carries information evolving over time about the region(s) of interest. A renderer processes the timeline and provides navigation information to a user using available means such as a graphical representation or haptic information, or a combination of several means.

Abstract: A method of sharing and a method of presenting virtual content in a mixed reality scene rendered on at least two user devices having different viewing position and/or orientation onto the mixed reality scene and corresponding apparatus are described. At a first user device, a user is enabled to select a virtual content to be shared and a second user device with whom the virtual content is to be shared. Information related to the virtual content to be shared is provided, wherein the provided information comprises the 3D position of the virtual content to be shared. The information is received by the second user device and the shared virtual content is rendered with regard to the viewing position and/or orientation of the second user device onto the mixed reality scene.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are described for the synchronization of multiple traffic flows of information such as protocol data unit (PDU) flows associated with applications and/or services. In an example embodiment, a device may receive one or more forwarding configurations to use when transmitting data in multiple flows. The forwarding configurations may lead to synchronized transmission of the multiple flows such that a delay between a (e.g., last or latest) PDU in a first flow and a (e.g., last or latest) PDU in a second flow satisfies one or more parameters, such as different expected time of arrival threshold values. In some embodiments, PDUs may be associated with an application data unit (ADU) in the first flow and an ADU in the second flow.

Abstract: A method performed by an anchor wireless transmit/receive unit (WTRU) having an Extended Reality (XR) application includes transmitting to a base station (BS) a request for a candidate set of collaborative WTRUs, the request including pose information to identify the candidate set of collaborative WTRUs, receiving from the BS a first set of collaborative WTRUs, determining, by the anchor WTRU, a second set of WTRUs from the first set of WTRUs that align with at least one of a Field of View (FoV) requirement, the pose information, and XR application parameters of the anchor WTRU, and transmitting, to the BS, an indication of the second set of WTRUs as selected collaborative WTRUs.

Abstract: The present disclosure describes solid compositions comprising a paraffin inhibitor and a corrosion inhibitor. The paraffin inhibitors include polymers having various repeat units containing one or more ester moieties. The corrosion inhibitors can be imidazoline compounds, quaternary ammonium compounds, or a combination thereof. These solid compositions can be used to treat subterranean hydrocarbon-containing reservoir and can inhibit or reduce paraffin deposition in the reservoir and/or inhibit or reduce corrosion in a piece of equipment in contact with the reservoir.

Abstract: A first communication device, e.g., having a camera, is pointed, by a first person, in direction of a second person with which the first person wants to communicate in an interactive session, using his communication device. The camera captures the face of the second person. If the second person does not have a device enabling interaction with the first device, a third person in proximity of the second person, having a device enabling interaction, is selected, and a request is transmitted to the second device in the hands of the third person to handover his device to the second person, displaying, for example, the face of the second person. When handover is detected, the second person may be identified by the device being handed over. The interaction between the first and the second device may be established.

Abstract: In an augmented reality system, helper data are associated to augmented reality anchors to describe the surroundings of the anchor in the real environment. This allows to verify that positional tracking is correct, in other words, that an augmented reality terminal is localized at the right place in an augmented reality scene. This helper data may be shown on request. Typical examples of helper data are a cropped 2D image or a 3D mesh.

Abstract: In an augmented reality system, a map of the real environment is generated from a 3D textured mesh obtained through captured data representing the real environment. Some processing is done on the mesh to remove unnecessary elements and generate the map that comprises a set of 2D pictures: one picture for the ground level and one picture for the other elements of the scene. The generated map may then be rendered on an augmented reality device. The ground and the non-ground content may be rendered independently, then additional elements, such as other users of the augmented reality scene or virtual objects, are localized and represented in the map in real-time using a proxy. The rendering can be adapted to the user poses and to the devices themselves.

In one embodiment, the method comprises receiving an image is received of a scene having a plurality of real objects and determining if at least one of these real objects is a reference object stored in a database. Subsequently, candidate shadow map of the reference object identified is retrieved when available and when a reference object cannot be identified, an object in the scene with adequate parameters is selected and the candidate shadow maps of this new reference object using said lighting parameters is computed.

Abstract: According to embodiments, a scene modelling system may (e.g., initially) obtain and (e.g., subsequently) update a model of a scene based on data describing the scene. The data describing the scene may be received from any of sensors and objects, for example, located in the scene. The scene may comprise a set of connected and unconnected objects. An object may be associated with its own part of the model that may have been built, for example in an initialization phase. A connected object may transmit its (e.g., part of) model to the scene modelling system (e.g., on demand or upon detection of any change). An unconnected object (e.g., and its status) may be recognized in the scene from an image of the object, for example, captured in the scene.

Abstract: Dynamic virtual content(s) to be superimposed to a representation of a real 3D scene complies with a scenario defined before run-time and involving real-world constraints (23). Real-world information (22) is captured in there al 3D scene and the scenario is executed at runtime (14) in presence of there al-world constraints. When there al-world constraints are not identified (12) from there al-world information, a transformation of the representation of the real 3D scene to a virtually adapted 3D scene is carried out (13) before executing the scenario, so that the virtually adapted 3D scene fulfills those constraints, and the scenario is executed in the virtually adapted 3D scene replacing the real 3D scene instead of there al 3D scene. Application to mixed reality.
