Engineering Contradiction Analysis
1Measurement precision
If sensor-equipped devices are worn by users to detect behavior, then behavior recognition capability is provided, but recognition accuracy deteriorates or fails depending on wearing position
Solution Approach 1:
The system dynamically switches between multiple behavior recognition modes (first mode for wrist-wearing, second mode for other positions) based on detected wearing position. This dynamic adaptation allows the recognition algorithm to adjust to different sensor locations, maintaining high accuracy regardless of where the device is worn.
Solution Approach 2:
The system changes recognition parameters by selecting different behavior recognition modes corresponding to different wearing positions. When the device is detected to be worn on the wrist, the first recognition mode is used; when worn elsewhere, the second mode is used. This parameter change approach optimizes recognition accuracy for each specific wearing scenario.
2Measurement precision
If a single behavior recognition mode is used for all wearing positions, then device complexity is reduced, but behavior recognition accuracy deteriorates
Solution Approach 1:
The behavior recognition function is segmented into multiple distinct modes (first behavior recognition mode for wrist-wearing, second behavior recognition mode for other positions). Each mode is optimized for specific wearing scenarios, allowing the system to maintain high accuracy without requiring a single overly complex universal recognition algorithm.
Solution Approach 2:
The wearing position detection unit acts as an intermediary that determines which behavior recognition mode to activate. Based on the detected wearing position, it selects the appropriate recognition mode, thereby managing the complexity by introducing a simple selection mechanism rather than requiring one complex recognition system to handle all positions.
