Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple recognition methods are used to improve recognition accuracy in complex environments, then recognition reliability is improved, but device complexity increases
Solution Approach 1:
The system dynamically adjusts the recognition method weight values based on environmental conditions and recognition confidence levels. Different recognition methods are adaptively selected and weighted according to the current scene characteristics, transforming a static multi-method system into a dynamic one that optimizes performance while managing complexity.
Solution Approach 2:
The system changes the weight parameters of different recognition methods based on environmental conditions and recognition confidence. By adjusting these weight parameters dynamically, the system can emphasize more reliable recognition methods in specific conditions, improving overall accuracy without permanently increasing system complexity.
2Measurement precision
If recognition confidence threshold is increased to improve accuracy, then measurement precision is improved, but loss of time increases due to repeated verification
Solution Approach 1:
The system uses recognition confidence levels as feedback to adjust the weight values of different recognition methods. When recognition confidence is high, the system can make decisions more quickly; when confidence is low, it can allocate more time for verification or switch to alternative recognition methods, optimizing the time-precision tradeoff.
Solution Approach 2:
The system performs preliminary recognition using multiple methods simultaneously and evaluates their confidence levels before making final decisions. This preliminary action allows the system to identify high-confidence results early and avoid unnecessary repeated verification, reducing time loss while maintaining precision.
3Adaptability or versatility
If adaptive weighting of recognition methods is implemented to handle varying environments, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system automatically adjusts the weight values of recognition methods based on environmental conditions and recognition confidence without requiring manual intervention. The system serves itself by dynamically optimizing its own performance, improving adaptability while avoiding the complexity of manual configuration and control.

AI summary
A recognition system and a recognition method for an interactive indicator are provided. The recognition method for the interaction indicator includes the following steps. At least one recognition method is used to recognize the interaction indicator. The recognition method is not exactly the same at different times. When the interaction indicator is recognized and a recognition confidence of the interaction indicator is higher than a predetermined level, a weight value of the recognition method is increased.
