Avatar Motion Prediction for Low-Latency Virtual Space Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual worlds like the metaverse, delays in user interactions due to physical distance to global data centers and network latency cause discomfort and inconvenience, and existing techniques merely mask these delays rather than eliminate them.
Innovation Solution
An information processing system with local servers predicting avatar motions in localized virtual spaces and a global server coordinating these predictions to minimize latency and resolve contradictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If virtual worlds are separated into multiple virtual spaces with independent updates, then discrepancies between virtual spaces are suppressed, but interaction delays cannot be theoretically avoided due to physical distance from global data centers
Solution Approach 1:
The system performs preliminary actions by predicting the motion of avatars in other virtual spaces before actual interactions occur. The prediction unit anticipates avatar movements based on current states and environmental information, allowing the display control unit to prepare and synchronize avatar motions in advance, thereby reducing interaction delays while maintaining virtual world consistency across multiple separated spaces
2Productivity
If network communication is optimized to reduce delays, then communication efficiency improves, but user discomfort and inconvenience in interaction operations persist
Solution Approach 1:
The system implements feedback mechanisms where the prediction unit continuously monitors avatar motions and environmental changes in real-time. This feedback loop allows the system to adjust predictions dynamically based on actual user interactions and environmental responses, ensuring that avatar motions are synchronized with user expectations and improving interaction comfort while maintaining high communication efficiency
3Loss of time
If prediction information is used to control avatar motion, then interaction delays are minimized, but system complexity increases due to prediction processing requirements
Solution Approach 1:
The system segments the prediction processing into distinct functional modules: a prediction unit that generates prediction information, a display control unit that uses predictions to control avatar motions, and a reception unit that handles communication. This segmentation allows each module to be optimized independently, reducing overall system complexity while maintaining effective prediction-based avatar control that minimizes interaction delays
