Solution Overview

Problem

Existing systems face high processing loads when replicating real-world traffic environments in virtual spaces due to frequent updates of moving body positions, which is inefficient and resource-intensive.

Innovation Solution

The system adjusts the update cycle for predictive moving body information based on the moving speed and location of each moving body, allowing longer update cycles for slower-moving bodies and aligning overlapping cycles to reduce processing load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the update cycle for moving body positions is minimized to accurately replicate real-world traffic environments, then the accuracy of the virtual space representation is improved, but the processing load on the updating device significantly increases

Engineering Contradiction:
Improveaccuracy of moving body position representationVSAvoidprocessing load
Core Design Contradiction:
Measurement precisionVSPower

Solution Approach 1:

The patent applies local quality by differentiating update cycles based on the movement characteristics of individual moving bodies. Fast-moving objects receive shorter update cycles for high accuracy, while slow-moving objects receive longer update cycles to reduce processing load. This localized differentiation resolves the contradiction by optimizing precision where needed without uniformly increasing processing load across all objects.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making the update cycle adaptive rather than fixed. The update cycle is dynamically adjusted based on the detected movement speed of each moving body, allowing the system to automatically optimize between accuracy and processing load. This dynamic adaptation enables the system to maintain high accuracy for fast-moving objects while reducing updates for slow-moving objects.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a uniform update cycle is used for all moving bodies to simplify processing, then the device complexity is reduced, but the processing load cannot be optimized based on movement characteristics

Engineering Contradiction:
Improvesimplicity of update cycle managementVSAvoidinefficiency of processing resources
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent transforms the static uniform update cycle into a dynamic adaptive cycle that automatically adjusts based on movement speed detection. This dynamic approach eliminates the need for complex manual configuration while enabling efficient resource utilization, resolving the contradiction between simplicity and optimization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs self-service by automatically detecting movement speeds and autonomously determining appropriate update cycles without external intervention. This self-adjusting mechanism maintains simplicity in operation while achieving efficient processing resource allocation based on actual movement characteristics.

Inventive Principle:
Principle #25Self-service

AI summary

An information processing system acquires moving body information that indicates a position of each of multiple moving bodies existing in the real world. The information processing system acquires, based on the moving body information, predictive moving body information at a prescribed cycle. The predictive moving body information indicates a predictive position of each of the multiple moving bodies after a point in time at which the moving body information is acquired. The information processing system is configured to set the cycle for acquiring the predictive moving body information in at least one zone among multiple zones in which the moving bodies are present to be longer than the cycle for acquiring the predictive moving body information in the other zones.
