Engineering Contradiction Analysis
1Productivity
If multiple devices and environments are interconnected for real-time collaboration, then user interaction capability and collaboration efficiency are improved, but system complexity and resource consumption increase
Solution Approach 1:
The patent implements a universal collaboration platform that functions across multiple device types (VR headsets, AR glasses, mobile devices, desktop computers) and environment types (virtual reality, augmented reality, physical space). The system provides consistent collaboration capabilities including document viewing, annotation, and spatial audio communication regardless of the specific device or environment being used, thereby improving collaboration efficiency without requiring separate systems for each device type.
Solution Approach 2:
The system introduces a central server as an intermediary that manages connections between multiple users across different devices and environments. The server handles document synchronization, user authentication, and coordination of collaboration sessions, thereby reducing the complexity burden on individual devices while enabling real-time multi-device collaboration.
2Speed
If data is transmitted across multiple devices in real-time, then collaboration responsiveness is improved, but network bandwidth consumption and latency increase
Solution Approach 1:
The patent implements selective data transmission where only the portions of documents and spatial audio data relevant to each user's current view and interaction are transmitted. The system determines which document sections need to be synchronized based on user focus areas and transmits only those specific portions, thereby maintaining real-time collaboration responsiveness while reducing overall network bandwidth consumption.
Solution Approach 2:
The system transmits data at varying levels of detail and frequency based on user interaction intensity. During periods of intense collaboration activity, more frequent updates are provided, while during quieter periods, transmission frequency is reduced. This partial action approach maintains necessary responsiveness while minimizing unnecessary network bandwidth consumption.
3Measurement precision
If high-fidelity spatial audio and document data are transmitted to all users, then audio quality and document detail are improved, but resource expenditure increases
Solution Approach 1:
The system transmits spatial audio data selectively based on user proximity and interaction context. Only users who are spatially close to or actively interacting with a particular document section receive high-fidelity audio data for that section. Other users receive reduced-fidelity audio or no audio data for distant sections, thereby maintaining audio quality where needed while reducing overall resource expenditure for audio transmission and processing.
Solution Approach 2:
The system dynamically adjusts audio transmission parameters including quality level, sample rate, and data format based on user context, device capabilities, and network conditions. This allows the system to maintain high audio fidelity when necessary while reducing resource consumption during normal collaboration, effectively managing the trade-off between audio quality and resource expenditure.
