Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G augmented and mixed reality devices face challenges in dynamically updating scenes, particularly for devices with limited computational resources, as the call flow for stand-alone AR/MR devices is not capable of efficiently managing scene descriptions.
Innovation Solution
A method involving an outer session loop for creating and updating scenes, and an inner session loop for rendering media content, allowing for dynamic scene updates while maintaining efficient bandwidth use by replacing irrelevant media objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If scene updates are implemented in stand-alone AR/MR devices, then dynamic scene capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the AR/MR system into two distinct operational modes: stand-alone mode where the device handles all processing locally, and edge-dependent mode where scene updates are managed by external servers. This segmentation allows the device to implement scene update capability without permanently increasing its internal complexity, as the complex scene management functions are offloaded to edge servers when needed.
Solution Approach 2:
The patent introduces dynamic switching between different operational modes (stand-alone and edge-dependent) based on network availability and computational needs. The device can dynamically transition between handling scene updates locally versus receiving them from edge servers, providing adaptability without fixed complexity increases.
2Adaptability or versatility
If computational resources are increased for scene processing, then scene update capability is improved, but device power consumption increases
Solution Approach 1:
The patent introduces edge servers as intermediary components that handle heavy scene processing and computational tasks. Instead of requiring the AR/MR device to have high computational resources, the edge servers act as intermediaries that perform scene management, rendering, and update operations, thereby reducing the power consumption requirements of the wearable device while maintaining advanced scene processing capabilities.
Solution Approach 2:
The patent replaces the mechanical/computational processing system within the device with a network-based distributed computing system. Scene processing tasks are substituted from local device computation to remote edge server computation, reducing the need for high-power local processors and associated energy consumption.
3Reliability
If full scene descriptions are streamed continuously, then scene update reliability is improved, but network bandwidth consumption increases
Solution Approach 1:
The patent extracts and transmits only the essential scene description data and update information from the full scene content. Instead of streaming complete scene descriptions continuously, the system extracts key scene metadata, object identifiers, and update deltas, significantly reducing bandwidth consumption while maintaining sufficient information for reliable scene reconstruction and updates at the device.
Solution Approach 2:
The patent changes the parameter of data transmission from complete scene descriptions to compressed scene update indicators. By transforming the data representation from full-scene to incremental-update format, the system achieves reliable scene updates with significantly reduced network bandwidth requirements.

AI summary
A method is provided. The method includes selecting a standalone augmented reality (STAR) media content including a scene for transmission over a 5G media streaming (5GMS) network, creating, in an outer session loop, an augmented reality (AR)/mixed reality (MR) session for streaming the STAR media content, rendering, in an inner session loop within the outer session loop, the STAR media content, and updating, in the outer session loop, the scene with a new scene by providing the new scene to the inner session loop while the inner session loop renders the STAR media content.
