Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only instructor and student images are displayed without difference information, then the display device shows simple visual information, but students cannot efficiently recognize posture or motion differences
Solution Approach 1:
The system introduces an intermediary component (difference information generation module) that processes instructor and student images to extract and highlight posture or motion differences. This intermediary automatically identifies key difference points and presents them to students, resolving the contradiction by providing comprehensive difference information without requiring complex manual analysis from students.
Solution Approach 2:
The system replaces the mechanical process of manual posture comparison with automated image processing and analysis algorithms. The controller automatically generates difference information by comparing instructor and student images, substituting manual mechanical comparison with computational analysis, thereby providing efficient difference detection without increasing device complexity.
2Productivity
If detailed difference information is provided to students, then practice efficiency improves, but the information processing system becomes more complex
Solution Approach 1:
The system extracts only the essential difference information between instructor and student postures or motions, separating key difference points from the complete image data. By taking out only the relevant difference information needed for practice improvement, the system enhances productivity without requiring overly complex processing apparatus.
Solution Approach 2:
The system applies local quality analysis by focusing on specific regions or features where posture or motion differences occur, rather than analyzing entire images uniformly. This localized approach provides detailed difference information where needed while reducing overall processing complexity in areas where differences are minimal.
3Reliability
If real-time difference notification is implemented, then students can immediately correct posture or motion errors, but the processing speed and computational load increase
Solution Approach 1:
The system performs preliminary processing by pre-identifying key posture or motion features and establishing comparison criteria before real-time analysis. This preliminary preparation enables faster real-time difference detection and notification, maintaining high reliability for posture correction while reducing processing speed requirements during actual practice.
Solution Approach 2:
The system implements partial real-time notification by providing difference information for the most critical posture or motion errors first, rather than analyzing and notifying all differences simultaneously. This approach ensures reliable correction of essential errors while maintaining acceptable processing speed by focusing computational resources on the most important differences.

AI summary
An information processing apparatus includes an interface configured to acquire an image of a first user, information regarding posture or motion of the first user, and information regarding posture or motion of a second user, and a controller configured to generate difference information regarding a difference between the posture or motion of the first user and the posture or motion of the second user. The controller is configured to notify the second user of the difference information while controlling a display device to display the image of the first user or an image of the second user.
