Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture detection is performed using a depth camera, then gesture control functionality is achieved, but position accuracy deteriorates due to distance and angle differences between camera and user eye
Solution Approach 1:
The system calculates position deviation based on distance and angle parameters between the depth camera and user eye, then applies correction to the detected gesture position. This transforms the raw detection parameters into corrected coordinates that align with the user's visual perspective, resolving the accuracy issue while maintaining ease of operation.
2Measurement precision
If conventional calibration methods are used to improve gesture position accuracy, then measurement precision improves, but device complexity and operation time increase
Solution Approach 1:
The system automatically calculates and applies position correction based on pre-determined geometric relationships between the camera and user eye. This self-correcting mechanism eliminates the need for manual calibration procedures, reducing both complexity and operation time while maintaining high measurement precision.
3Measurement precision
If manual calibration procedures are implemented, then gesture position accuracy improves, but ease of operation deteriorates due to tedious detection processes
Solution Approach 1:
The system performs automatic position correction without requiring user intervention in calibration procedures. By computing the correction based on fixed geometric parameters and applying it transparently, the system maintains high accuracy while making the process as easy as simply using the gesture control functionality.
