Metaverse Object Synchronization With Lazy Global Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metaverse systems face challenges in maintaining consistent object states across multiple local metaverses while optimizing network communication and resource usage, particularly when actions in one local metaverse do not require global synchronization.
Innovation Solution
Implementing a lazy consistency model that only synchronizes object state changes in a global metaverse when they are irreversible or globally observable, and dynamically adjusting object fidelity based on agent perception and interaction.

1Reliability
If all object state changes are synchronized across all local metaverses, then global consistency is maintained, but network communication overhead and resource usage increase significantly
Solution Approach 1:
The system applies different synchronization qualities to different object state changes based on their characteristics. Globally observable and irreversible actions trigger full synchronization across all local metaverses, while locally observable reversible actions are kept local without propagation. This selective approach maintains necessary global consistency while reducing unnecessary network communication overhead.
Solution Approach 2:
The synchronization system is segmented into multiple pathways: local synchronization for reversible actions, global synchronization for irreversible actions, and conditional propagation for globally observable actions. This segmentation allows the system to apply appropriate synchronization depth to each type of state change, optimizing the balance between consistency and communication efficiency.
2Loss of information
If object state changes are propagated to all local metaverses immediately, then all agents see consistent state, but resource usage and network traffic increase
Solution Approach 1:
The system evaluates each state change's characteristics (reversibility, observability) and applies corresponding propagation quality. Reversible locally observable changes remain local with no propagation, while irreversible and globally observable changes are propagated selectively. This reduces network traffic by eliminating unnecessary propagations while preserving essential state consistency information.
Solution Approach 2:
Instead of fully propagating all state changes to all local metaverses, the system applies partial propagation only where necessary based on action characteristics. This partial action approach maintains sufficient state consistency for multi-agent coordination while significantly reducing overall network traffic volume.
3Manufacturing precision
If the system maintains high fidelity object representations in all local metaverses, then agent experience quality is improved, but resource consumption increases
Solution Approach 1:
Object fidelity is adjusted locally based on the specific needs of each local metaverse and the characteristics of objects within it. High fidelity is maintained for objects that are locally observable and interacted with, while lower fidelity or omitted representations are used for objects that do not require detailed local representation. This selective fidelity approach improves agent experience quality for relevant objects while reducing overall resource consumption.

AI summary
Adaptive synchronization of objects in a distributed metaverse is provided. An agent of a user of a global metaverse is detected performing an action on an object within a scene of a local metaverse corresponding to the user. A state change in the object caused by the action performed by the agent of the user in a local context of the local metaverse corresponding to the user is stored. It is determined whether the action performed by the agent on the object is globally observable or an irreversible action. The state change in the object caused by the action performed by the agent of the user in the local context of the local metaverse corresponding to the user is propagated to a plurality of different local metaverses of the global metaverse in response to determining that the action performed by the agent is globally observable or an irreversible action.
