Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in intuitively assisting users in acquiring complex techniques, as they struggle to differentiate between desired and actual movements, especially when multiple body parts are involved, and often rely on single sensor devices, limiting their ability to provide effective feedback for complex movements.
Innovation Solution
A system comprising multiple sensor units and output units that calculate differences between master data and motion data from multiple sensor units, using tactile stimuli to guide users in correcting their movements by outputting feedback at specific positions corresponding to the sensor units, allowing for more intuitive and effective learning of complex techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single sensor device is used to collect sensor information, then the device complexity is reduced, but the ability to assist in improving complex techniques that require multiple movements is insufficient
Solution Approach 1:
The system divides the monitoring function into multiple sensor devices positioned at different locations (e.g., sensor device 1 at the tennis racket, sensor device 2 at the user's body). Each sensor device collects specific motion data independently, allowing the system to track complex multi-part movements simultaneously without requiring a single complex sensor unit.
Solution Approach 2:
The information processing device acts as an intermediary that receives and integrates data from multiple sensor devices. It generates sensor information representing the relationship between multiple body parts by combining data from different sensors, enabling complex technique analysis without directly connecting all sensors to a single processing unit.
2Loss of information
If feedback is provided only for actions similar to user movements, then the feedback system is simple, but the user cannot intuitively recognize differences between desired and actual movements
Solution Approach 1:
The system provides feedback by displaying images that visually represent the relationship between multiple body parts during user movements. This visual feedback mechanism allows users to intuitively recognize movement differences and patterns, improving their understanding of proper technique without requiring complex numerical data processing.
Solution Approach 2:
The system creates visual copies or representations of the user's actual movements and compares them with desired movement patterns. By generating and displaying image representations of sensor data, the system enables users to see and understand movement differences more intuitively than through raw sensor data alone.
3Measurement precision
If sensor information from multiple sensor devices is integrated, then the ability to analyze complex movements is improved, but the information processing complexity increases
Solution Approach 1:
The information processing device serves as an intermediary that automatically integrates and processes data from multiple sensor devices. It generates meaningful sensor information representing relationships between body parts without requiring manual processing, reducing the complexity burden on users while maintaining high measurement precision.
Solution Approach 2:
The system performs self-service by automatically generating and processing sensor information from multiple sources. The information processing device independently handles the integration and analysis of data from multiple sensor devices, producing ready-to-use sensor information without requiring external intervention or complex user-side processing.
