    Abstract: One example of a method includes receiving a plurality of video streams depicting a scene, wherein the plurality of video streams provides images of the scene from a plurality of different viewpoints, identifying a target that is present in the scene, wherein the target is identified based on a determination of a likelihood of being of interest to a viewer of the scene, determining a trajectory of the target through the plurality of video streams, wherein the determining is based in part on an automated visual analysis of the plurality of video streams, wherein the determining is based in part on a visual analysis of the plurality of video streams, rendering a volumetric video traversal that follows the target through the scene, wherein the rendering comprises compositing the plurality of video streams, receiving viewer feedback regarding the volumetric video traversal, and adjusting the rendering in response to the viewer feedback.

    Abstract: In one example, the present disclosure improves simulations based on the use of digital twins using social automatons. In one example, a method performed by a processing system including at least one processor includes constructing a digital twin of a physical environment, constructing a social automaton, wherein the social automaton comprises a virtual representation of an individual that is programmed to exhibit behaviors and characteristics of the individual, and inserting the social automaton into the digital twin to create an extended reality media in which interactions of the social automaton with the digital twin simulate interactions of the individual with the physical environment.

    Abstract: Methods, computer-readable media, and apparatuses for adjusting a network-controllable physical resource of a sensory service in response to biometric data for a group of users are disclosed. In one example, a processing system including at least one processor may gather biometric data of each user of a group of users of a sensory service. The sensory service may comprise at least one network-controllable physical resource. The processing system may then aggregate the biometric data for the group of users and tailor the sensory service for the group of users based upon the biometric data for the group of users that is aggregated. In one example, the tailoring of the sensory service may include adjusting the at least one network-controllable physical resource in response to the biometric data that is aggregated for the group of users.

    Abstract: A traffic management system that manages policy agreements between operators and visual indicator devices receives first sensor data from a physical environment. The traffic management system computationally processes the first sensor data to identify a first visual indication in the sensor data and determines that the first visual indication is associated with first policy agreement. The traffic management system then determines, based on the first sensor data, that a first visual indicator system that provided the first visual indication is violating a first policy included in the first policy agreement and, in response, provides a policy violation notification that the first visual indicator system is violating the first policy.

    Abstract: A processing system of a mobile device may determine the device's predicted viewport, which defines a portion of a real world environment that is expected to be visible to the device's user at a future time. The processing system may determine a set of extended reality anchors that are present in the real world environment, where each anchor stores a digital object that, when rendered by the device and presented to the user simultaneously with the real world environment, creates extended reality media. The processing system may remove a first subset anchors from the set, where locations of anchors in the first subset fall outside a threshold distance from the predicted viewport. The removing results in a second subset of anchors remaining in the set. The processing system may download a digital object from a second device, where the digital object is stored by an anchor of the second subset.

    Abstract: A method for validating objects appearing in volumetric video presentations includes obtaining a volumetric video presentation depicting a scene, wherein the volumetric video presentation is associated with a metadata file containing identifying information for the scene, identifying user-generated content that depicts the scene, by matching metadata associated with the user-generated content to the metadata file associated with the volumetric video presentation, comparing a first object appearing in the volumetric video presentation to a corresponding second object appearing in the user-generated content, assigning a score to the first object based on the comparing, wherein the score indicates a probability that the first object has not been manipulated, and altering the volumetric video presentation to filter the first object from the volumetric video presentation when the score falls below a threshold.
