Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration data is obtained by capturing audio content using multiple microphones, then the quality of spatial audio capture is improved, but the complexity of the operation process increases
Solution Approach 1:
The system automatically determines when calibration data needs to be obtained and initiates the calibration process without requiring manual user intervention. The apparatus self-manages the calibration workflow, including detecting user inputs and triggering appropriate calibration routines, thereby reducing operational complexity while maintaining high measurement precision.
Solution Approach 2:
The system performs calibration data collection in advance during normal video capture operations. By utilizing user zooming inputs as opportunities to collect calibration data, the system prepares spatial audio capture capabilities beforehand, ensuring high-quality audio recording is ready when needed without adding complexity to the main workflow.
2Loss of information
If user inputs are utilized to modify zooming operation and add deviation, then calibration data collection is enhanced, but the ease of operation deteriorates
Solution Approach 1:
The system monitors user zooming inputs in real-time and provides feedback by detecting when specific input patterns occur. When a user performs a zooming operation, the system recognizes this as an opportunity to collect calibration data and automatically triggers the calibration routine, creating a seamless feedback loop that enhances data collection without requiring users to understand the underlying calibration process.
Solution Approach 2:
The system acts as an intermediary between user zooming gestures and calibration data collection. Instead of directly requiring users to perform complex calibration maneuvers, the system intercepts normal zooming inputs and translates them into calibration opportunities, thereby maintaining ease of operation while improving calibration data completeness.
3Measurement precision
If deviation is added to zooming operation, then spatial audio calibration accuracy is improved, but the time required for calibration increases
Solution Approach 1:
The system collects calibration data periodically during normal video capture operations whenever user zooming inputs occur. Rather than requiring a dedicated, time-consuming calibration session, the system accumulates calibration data through periodic opportunities during regular usage, thereby improving calibration accuracy without significantly increasing the time users perceive they are spending on calibration.
Solution Approach 2:
The system performs calibration data collection in advance during normal operational activities. By gathering calibration data whenever users naturally perform zooming operations during video capture, the system prepares accurate spatial audio calibration beforehand, ensuring high measurement precision is achieved without requiring separate, time-consuming calibration sessions.
