Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If environmental information is generated using sound detection from a microphone unit, then the virtual experience realism is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex multi-sensor environmental detection systems with a simplified acoustic-based detection system. By using a microphone unit to detect sound characteristics (wind noise, footstep sounds, voice volumes) and converting these acoustic signals into environmental information, the system achieves realistic virtual experience without requiring complex mechanical or electronic sensor arrays for direct wind, terrain, or noise detection.
2Reliability
If multiple types of environmental information (wind, ground surface, noise) are generated in real-time, then the interaction realism is improved, but the processing time increases
Solution Approach 1:
The system continuously processes acoustic signals from the microphone unit to generate multiple types of environmental information simultaneously in real-time. By maintaining continuous acoustic monitoring and processing, the system can dynamically update wind conditions, ground surface information, and noise levels without interruption, ensuring realistic virtual object interactions while minimizing processing delays through ongoing signal analysis.
Solution Approach 2:
The microphone unit serves multiple functions: detecting wind noise for wind direction/speed estimation, capturing footstep sounds for ground surface material identification, and measuring ambient noise levels. This multi-functional use of a single acoustic sensor reduces the need for multiple specialized sensors and enables simultaneous generation of diverse environmental information from a unified detection system.
