Engineering Contradiction Analysis
1Measurement precision
If rendering is performed based on tracking information for user movement, then the accuracy of virtual environment reflection is improved, but the synchronization timing and processing complexity worsen
Solution Approach 1:
The system performs preliminary actions by obtaining tracking information in advance before rendering is required. The processor receives tracking information from sensors and stores it temporarily, so that when rendering needs to occur, the data is already prepared and available, eliminating delays caused by real-time data collection during the rendering process.
Solution Approach 2:
The system dynamically adjusts the timing of rendering operations based on the availability of tracking information. The processor determines rendering start timing flexibly by considering when tracking information has been obtained and is ready, rather than using fixed timing intervals. This dynamic approach ensures that rendering always uses the most current available tracking data while maintaining efficient processing.
2Measurement precision
If rendering is performed based on tracking information for user movement, then the accuracy of virtual environment reflection is improved, but the device complexity worsens
Solution Approach 1:
The system segments the rendering process into distinct phases: tracking information acquisition, data preparation, timing determination, and actual rendering execution. By dividing the complex rendering workflow into manageable segments, the processor can handle each stage independently with specialized logic, reducing overall system complexity while maintaining high accuracy in movement reflection.
