Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual reality system connects each source to every sink with realtime data streams, then communication completeness is improved, but computational resource requirements increase
Solution Approach 1:
The patent segments the virtual reality system into distributed network nodes, each independently managing its own audio and graphic rendering based on position information. This segmentation allows the system to maintain complete communication connectivity while distributing computational load across multiple nodes rather than requiring centralized processing of all data streams.
Solution Approach 2:
The patent implements dynamic connection management where realtime data stream connections are established or terminated based on relative distances between objects. When separation distance exceeds a maximum threshold, connections are automatically terminated, and when within threshold, connections are established. This dynamic approach maintains communication completeness for relevant users while reducing computational requirements by eliminating connections to distant users.
2Productivity
If virtual reality system establishes realtime data stream connections based on distance thresholds, then computational efficiency is improved, but communication completeness deteriorates
Solution Approach 1:
The patent changes the parameter of connection establishment from static (all-or-nothing connections) to dynamic (distance-based connections). By using relative distance as a variable parameter, the system automatically adjusts which connections are maintained, optimizing the balance between computational efficiency and communication completeness based on actual spatial relationships between users.
Solution Approach 2:
Each virtual reality software application on user computers autonomously configures its own audio and graphic rendering based on position information received from other users or a presence server. This self-service approach allows each node to independently manage its connections based on local distance calculations, achieving computational efficiency without sacrificing communication completeness.
3Productivity
If virtual reality system uses high-processing-power computing devices, then realtime communications performance is improved, but system accessibility deteriorates
Solution Approach 1:
The patent segments the processing requirements into distributed components at each network node, eliminating the need for any single high-processing-power device. Each node only needs to handle its own audio and graphic rendering based on local position information, making the system accessible to devices with modest computing power while maintaining overall realtime performance.
Solution Approach 2:
The patent implements partial action by establishing data stream connections only when distance thresholds are met, rather than maintaining all possible connections. This partial connection approach reduces the processing burden on each device to only the necessary minimum, improving accessibility while maintaining sufficient realtime performance for connected users.

AI summary
A realtime kernel supports realtime communications between communicants operating on respective network nodes. The realtime kernel handles the complex tasks of connecting to communicants, virtual areas, and other network resources, switching those connections in response to user inputs, and mixing realtime data streams. The realtime kernel enables developers to focus on developing high-level communications functionality instead of low-level plumbing code. The realtime kernel imposes relatively low computational resource requirements so that realtime communications performance can be achieved using a wide range of computing devices and network connections that currently are available.
