Motion Analysis Display for Switching Check Item Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion analysis systems, such as described in Japanese Patent Application Laid-open No. 2022-104413, fail to display the positions of multiple check items in a golf swing or other motions in an easy-to-understand manner.
Innovation Solution
A motion analysis system and method that includes frame image extraction, scene determination, position identification, and display control to clearly show the positions of objects corresponding to check items in different scenes of a motion, allowing for easy switching between scenes and check items based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple check items are displayed in a motion analysis system, then the quantity of information is improved, but the ease of understanding deteriorates
Solution Approach 1:
The display is segmented into multiple independent check item display regions, each showing one check item at a time. This segmentation allows the system to present multiple check items (improving quantity of information) while maintaining ease of understanding by focusing on one item at a time without cluttering the display with all check items simultaneously.
Solution Approach 2:
The system dynamically switches between different check items based on user input or automatic progression. This dynamic behavior allows the display to adaptively present check items in a manageable sequence, improving both the quantity of information available and the ease of understanding by preventing information overload through controlled, step-by-step presentation.
2Loss of information
If all check items are displayed simultaneously, then the completeness of information is improved, but the ease of operation deteriorates
Solution Approach 1:
The system segments the complete set of check items into individual display units, each representing one check item. This segmentation enables the system to maintain completeness of information (all check items are available) while improving ease of understanding by presenting them in discrete, manageable portions rather than all at once.
Solution Approach 2:
The system prepares all check items for display but executes them sequentially or on demand rather than all simultaneously. This preliminary preparation ensures completeness of information is maintained, while the staged execution improves ease of understanding by avoiding information overload and allowing users to process information at their own pace.
3Measurement precision
If the system displays detailed position information for each check item, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The system extracts and displays only the essential position information for each check item rather than all possible detailed measurements. This extraction approach maintains measurement precision for the critical parameters while reducing display control complexity by focusing on the most important information and omitting redundant details.
Solution Approach 2:
The system applies different display qualities to different check items based on their importance and complexity. Critical check items receive detailed position information, while less critical items receive simplified representations. This local quality differentiation maintains measurement precision where needed while reducing overall display control complexity by avoiding uniform high-detail rendering across all check items.

AI summary
An evaluation result information transmission module displays an identified display image, which is a frame image in which a position of an object corresponding to any one of a plurality of check items associated with a scene is displayed to be identified. The evaluation result information transmission module changes, in response to reception of a check item change request, the displayed identified display image from the frame image in which the position of the object corresponding to the one of the check items is displayed to be identified to the frame image in which the position of an object corresponding to a check item different from the one of the check items is displayed to be identified.
