Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional evaluation methods are used to assess user operations, then evaluation functionality is provided, but the operation burden on users is high and the interface is not user-friendly
Solution Approach 1:
The evaluation interface is segmented into distinct functional areas: level display unit showing current evaluation standard level, instruction input unit for receiving user commands, and output communication with the evaluation system. This segmentation allows users to interact with only the necessary components (level selection and confirmation) rather than navigating complex evaluation parameters, reducing operational burden while maintaining comprehensive evaluation functionality
Solution Approach 2:
The interface device acts as an intermediary between the user and the evaluation system. It translates simple user inputs (level selection via instruction input unit) into standardized evaluation standard level information that the evaluation system can process. This intermediary role shields users from complex evaluation mechanics while ensuring accurate data transmission, effectively reducing operational burden without sacrificing evaluation thoroughness
2Measurement precision
If detailed evaluation standards are implemented to accurately assess user skill levels, then evaluation precision is improved, but the complexity of the interface increases
Solution Approach 1:
The complex evaluation standard details are extracted from the user interface and retained within the evaluation system. The interface only exposes the essential selection mechanism (level display unit and instruction input unit), while the comprehensive evaluation criteria, measurement parameters, and assessment algorithms remain hidden in the backend evaluation system. This extraction maintains high evaluation precision through detailed standards while presenting a simple, non-complex interface to users
Solution Approach 2:
The interface dynamically adapts to user needs by displaying only the current evaluation standard level through the level display unit without overwhelming users with all possible evaluation parameters. The system dynamically processes the selected level information and communicates appropriately with the evaluation system, maintaining interface simplicity while supporting detailed evaluation through dynamic information presentation and processing

AI summary
An interface device supports information transmission between an evaluation system that evaluates an operation by a user to an operation object and the user. The interface device includes: a display configured to display information to the user; an instruction input unit configured to receive an instruction by the user; and a processor configured to execute processing of displaying, on the display, a level display unit which displays a level of an evaluation standard for the operation by the user in the evaluation system, processing of switching display of the level display unit according to an up or down instruction of the level inputted to the instruction input unit, and processing of outputting evaluation standard level information indicating the level corresponding to the display of the level display unit to the evaluation system.
