Multi-Sensor Motion Analysis Apparatus for Sports Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion analysis technologies using a single sensor can only provide limited visualization of a player's motion, whereas using data from multiple sensors offers the potential for more comprehensive visualization but lacks effective methods to integrate and display this information effectively.
Innovation Solution
An information processing apparatus and method that receives and analyzes data from multiple sensors, such as those attached to a player's glove and wristband, to generate distinct visual information about the player's motion, including trajectory and body state changes, facilitating better visualization and analysis of complex movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data from multiple sensors is used for motion analysis, then the comprehensive visualization of player motion is improved, but the complexity of data integration and processing increases
Solution Approach 1:
The patent divides the motion analysis system into separate sensor units (glove sensor and wristband sensor) that independently collect data, then integrates these segmented data streams through the information processing apparatus to achieve comprehensive multi-lateral motion visualization
Solution Approach 2:
The information processing apparatus performs multiple functions including receiving data from different sensor types, analyzing motion parameters, and generating various visual representations (trajectory, body state changes), making it a universal solution for multi-sensor data integration
2Measurement precision
If multiple sensors are attached to the user, then the measurement precision of motion parameters is improved, but the device complexity increases
Solution Approach 1:
Different sensors are placed at specific locations (glove and wristband) to measure different motion parameters locally, with each sensor optimized for its specific measurement function, thereby improving overall measurement precision without requiring all sensors to be complex
Solution Approach 2:
The information processing apparatus acts as an intermediary that receives raw data from multiple sensors, standardizes the data formats, and processes them into coherent motion representations, simplifying the overall system architecture
Data Source
AI summary
An apparatus includes a communications interface that receives first sensed data from a first sensor attached to a user and second sensed data from a second sensor attached to a user. That apparatus also includes circuitry that analyzes the first sensed data and the second sensed data and provides a display signal that causes a display to produce first visual information regarding a motion of the user and second visual information regarding the motion of the user, the first visual information being different than the second visual information.
