XR Dynamic Content Movement With Semantic Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extended reality (XR) systems lack effective methods to manage and control the movement and display of dynamic content units, particularly in mobile scenarios, leading to unregulated deployment of digital content that disregards safety, property rights, and environmental considerations.
Innovation Solution
A system that integrates spatial mapping and semantic understanding to define dynamic content units in three-dimensional space, enabling geospatial and object-based access controls to manage the movement and display of XR overlays, using edgecloud computing for real-time data processing and bidding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic content units are allowed to move freely through extended reality environments, then content delivery flexibility and user engagement are improved, but control over quality, safety, and property rights deteriorates
Solution Approach 1:
The system performs preliminary actions by defining access controls, semantic maps, and range of motion constraints for dynamic content units before they are deployed in the extended reality environment. This pre-establishment of rules and boundaries enables flexible content movement while maintaining quality and safety control through pre-defined parameters and restrictions.
2Reliability
If access control mechanisms are implemented to prevent display in restricted areas, then property rights and safety are protected, but system complexity increases
Solution Approach 1:
The system introduces a semantic map as an intermediary layer that mediates between dynamic content units and the extended reality environment. This semantic map contains access control information and range of motion definitions, allowing the system to protect property rights and safety without requiring complex direct control mechanisms between content units and restricted areas.
3Manufacturing precision
If semantic mapping and access control application are performed in real-time, then content placement accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-defining semantic maps, access control rules, and range of motion parameters before dynamic content units are deployed. This pre-processing approach enables accurate real-time content placement without requiring complex computational resources during runtime, as the heavy lifting of semantic understanding and access control definition is completed in advance.

AI summary
A method of a system of one or more electronic devices supports an extended reality application at a user device. The method includes receiving location and pose information of the user device related to an extended reality environment, determining at least one dynamic content unit relevant to the location and pose information, determining a range of motion of the at least one dynamic content unit, determining semantic information for the location and pose of the user device, generating a semantic map from the semantic information, applying at least one access control to the semantic map to prevent display of dynamic content on the dynamic content unit at a location in the semantic map, querying a dynamic content manager for dynamic content to be displayed as an extended reality overlay, and returning the dynamic content to the user device.
