Player State Display System for Athlete Motion Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for displaying the motion state of athletes, such as swimmers, struggle to easily determine the motional state from the displayed stroke information, lacking effective visualization of movement zones and numerical data.
Innovation Solution
A player state display system that generates a video by superimposing a player state display image, visualizing movement zones and numerical data, onto a video of the athlete in motion, allowing for easy determination of the motional state through a processor-driven process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If stroke information is displayed using graphs showing transition of time required for each stroke, then quantitative measurement data is provided, but the motional state of the player cannot be easily determined
Solution Approach 1:
The patent overlays motion state information (movement zones, stroke phases, body positions) as visual layers on top of the video footage, adding a spatial/visual dimension to the data presentation. This allows simultaneous display of quantitative stroke metrics and qualitative motion visualization without requiring separate graphs, making the motional state easily determinable while preserving measurement precision.
Solution Approach 2:
The patent combines multiple information types (video footage, stroke timing data, movement zone visualization, phase identification) into a single integrated display. By merging the quantitative stroke information with visual overlays showing arm movement zones and body position, the system provides both precise measurement data and easy visual interpretation of the player's motional state.
2Ease of operation
If video footage of the player in motion is displayed alone, then the player's motion is visible, but quantitative stroke information is not provided
Solution Approach 1:
The system merges video footage with quantitative stroke information by overlaying data layers on the video. This includes displaying movement zones, stroke phase identifiers, and timing data simultaneously with the visual footage, providing both qualitative observation and precise measurement without requiring separate displays.
Solution Approach 2:
The patent adds information dimensions to the video display by overlaying quantitative data (stroke timing, movement zones, phase identification) as visual layers. This transforms the simple video into a multi-layered information display that provides both visual motion observation and precise measurement data in a unified interface.
3Adaptability or versatility
If manual observation and measurement by human watchers is used, then flexible assessment is possible, but the process is time-consuming and less accurate
Solution Approach 1:
The patent replaces the mechanical system of manual observation and measurement with an automated image processing and analysis system. The system uses computer vision to automatically track player motion, identify stroke phases, calculate timing data, and generate visual overlays, eliminating the time-consuming manual process while maintaining flexible assessment capabilities through programmable analysis parameters.

AI summary
A motional state of a player in a video displaying the player in motion is easily determined. This player state display system includes a display device which displays a player video that includes information related to a motional state of the player. A processor generates, based on information that is obtained from an analysis video obtained by capturing the player in motion, a player state display image obtained by visualizing a movement zone corresponding to at least one predetermined motion of the player, and generates, as the player video, a video obtained by superimposing the player state display image on the video including the player in motion.
