Body Part Recognition System for Posture Evaluation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for evaluating and assisting human action and posture from photographic moving images do not provide sufficient assistance to users, making it difficult for them to achieve correct actions and postures.
Innovation Solution
An information processing device and method that recognizes predetermined body parts from an input image, evaluates the difference between the recognized parts and reference parts, and notifies the user of the differences to assist in taking correct action and posture, using a television receiver configuration with a camera, image processor, and action/posture evaluation assistance unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only human action and posture are evaluated from photographed moving images, then the system is simple to operate, but the assistance provided to users is insufficient
Solution Approach 1:
The system segments the evaluation process into multiple independent modules: body part recognition module, action evaluation module, posture evaluation module, and assistance generation module. Each module handles a specific aspect of the evaluation, allowing the system to provide comprehensive assistance without overwhelming complexity.
Solution Approach 2:
The system introduces an intermediary assistance generation unit that processes the evaluated action and posture data, compares it with reference standards, and generates actionable feedback. This intermediary layer transforms raw evaluation data into user-friendly guidance, enhancing assistance quality while maintaining system manageability.
2Measurement precision
If multiple special sensors are mounted on clothes to monitor posture, then the measurement precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The system replaces mechanical sensor-based posture monitoring with a visual-based recognition system using image processing algorithms. This substitution eliminates the need for users to wear special sensor-equipped clothing, significantly improving ease of operation while maintaining posture detection accuracy through advanced image analysis techniques.
Solution Approach 2:
Instead of using physical sensors on the body, the system creates a digital copy or model of the user's posture by analyzing images from standard cameras. This virtual modeling approach achieves accurate posture measurement without requiring users to interact with or wear specialized equipment.
