3D Gymnastics Scoring Display With Element-Based Index Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of selecting evaluation indexes for scoring gymnastics competitions is cumbersome for juries due to the large number of options available, which increases the time required for scoring and reviewing video playback.
Innovation Solution
A system utilizing a 3D laser sensor and camera to capture and analyze gymnastic movements, generating 3D models and recognizing elements, and displaying only relevant evaluation indexes for the current element being scored, reducing the need for manual selection by juries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all evaluation indexes are displayed for jury selection, then complete scoring information is available, but the selection process becomes cumbersome and time-consuming
Solution Approach 1:
The system extracts and displays only the evaluation indexes that are relevant to the currently playing video clip, rather than showing all possible evaluation indexes. This is achieved by the control unit determining which evaluation indexes correspond to the element being performed in the video, and the display unit showing only those specific indexes to the jury, thereby reducing information overload while maintaining scoring completeness.
Solution Approach 2:
The evaluation indexes are segmented and organized according to the specific element being scored. Instead of presenting a single comprehensive list of all evaluation indexes, the system divides them into groups based on the element type (e.g., floor exercise, pommel horse, still rings), and only displays the segment relevant to the current video playback, making the selection process more efficient.
2Measurement precision
If multiple evaluation indexes are provided for element assessment, then scoring accuracy is improved, but the complexity of the scoring process increases
Solution Approach 1:
The system performs preliminary identification of the element being performed in the video clip before the jury needs to select evaluation indexes. The control unit determines which element is being executed and pre-determines the corresponding evaluation indexes, so that when the video is played back, the relevant indexes are already prepared and displayed, reducing the complexity of the scoring process while maintaining accuracy.
Solution Approach 2:
The control unit acts as an intermediary between the video playback system and the display unit. It receives information about the element being performed, processes this information to determine the appropriate evaluation indexes, and then transmits only those specific indexes to the display unit for presentation to the jury, thereby simplifying the overall system complexity while ensuring scoring accuracy.

AI summary
An information processing apparatus (100) acquires a recognition result of a plurality of elements included in a series of exercise that have been recognized based on 3D sensing data for which the series of exercise by a competitor in a scoring competition is sensed and element dictionary data in which characteristics of elements in the scoring competition are defined. The information processing apparatus identifies, based on the recognition result of the elements, a displayed element in a 3D model video corresponding to the series of exercise based on the 3D sensing data. The information processing apparatus determines a part of options to be a subject of display, in accordance with the displayed element, out of a plurality of options corresponding to a plurality of evaluation indexes concerning scoring of the scoring competition. The information processing apparatus displays the part of options in a mode to be selectable.
