Solution Overview
Problem
Existing systems fail to effectively evaluate and improve users' walking posture, leading to inefficient energy consumption and potential fatigue, as they do not adequately measure and provide feedback on joint range of motion and muscle usage during walking.
Innovation Solution
A measurement system that includes a terminal apparatus and a server, utilizing sensors and RGB-D cameras to assess users' movements, providing real-time feedback and exercise regimens to enhance walking posture by evaluating joint range of motion and muscle usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional video evaluation methods are used to assess user movement, then the evaluation process is simple, but the measurement precision of joint range of motion and muscle usage is insufficient
Solution Approach 1:
The patent combines multiple sensing technologies (RGB-D cameras, depth sensors, skeleton extraction algorithms) into an integrated evaluation system that simultaneously captures both visual appearance and skeletal movement data, achieving precise joint range of motion measurement without requiring separate specialized devices
Solution Approach 2:
The patent replaces traditional mechanical measurement devices (such as goniometers and physical measurement tools) with optical sensing systems that use RGB-D cameras and computer vision algorithms to non-contactly measure joint angles and movement trajectories, eliminating the need for physical contact and complex mechanical apparatus
2Measurement precision
If detailed movement analysis is performed to improve walking posture evaluation, then the evaluation accuracy improves, but the energy consumption and processing time increase
Solution Approach 1:
The patent extracts only the essential skeletal movement data and joint angle information from the complete video feed, discarding redundant visual information. This selective extraction of critical parameters enables accurate posture evaluation while minimizing data processing requirements and energy consumption
Solution Approach 2:
The patent implements real-time evaluation at key moments during movement (such as peak joint angles and transition points) rather than continuous full-frame analysis, achieving sufficient evaluation accuracy with reduced computational load and lower energy consumption
3Productivity
If real-time feedback is provided to users about their movement, then the effectiveness of posture improvement increases, but the system complexity and processing requirements increase
Solution Approach 1:
The patent implements a closed-loop feedback system that continuously monitors user movement, compares it against ideal movement patterns, and provides real-time corrective guidance. This feedback mechanism enables users to self-correct their posture during exercise, significantly improving the efficiency of posture improvement without requiring complex manual intervention
Solution Approach 2:
The system enables users to independently evaluate and improve their own posture through automated analysis and feedback, eliminating the need for professional trainers or manual assessment. Users receive personalized guidance based on their individual movement patterns, allowing them to conduct effective training sessions autonomously

AI summary
An information processing apparatus includes a processor and a memory with instructions thereon. The instructions upon execution by the processor, causes the processor to: sequentially sense a movement of a body of a user; present, to the user, an avatar corresponding to the user, rather than a photographed image of an appearance of the user, based on a result of the sensing so that the user perceives a shape of a surface of the body of the user; determine a position of a figure object to be drawn that serves as a guide for movement of the body of the user in association with the avatar based on the result of the sensing; and display the figure object at the determined position.
