Half Mirror Posture Evaluation Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating and improving posture during rehabilitation or physical exercises are difficult for non-experts to understand, as they require complex interpretations of center-of-gravity lines and posture indexes, making it hard for individuals to visualize and correct their posture without professional explanation.
Innovation Solution
A video image information processing apparatus that includes a half mirror, imaging unit, extraction unit, measurement unit, evaluation unit, and display unit to visualize posture evaluation indexes by superimposing measurement data onto a video image, using computer graphics to intuitively show correction directions and amounts, allowing users to see their ideal posture or posture improvements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If posture evaluation indexes are displayed using technical terms like center-of-gravity line on x-ray images, then measurement precision is improved, but ease of operation deteriorates because non-experts cannot understand the displayed information
Solution Approach 1:
The patent creates a virtual image that copies and overlays evaluation results (such as posture deviation indicators) directly onto the video image of the subject. This allows non-expert users to see their posture evaluation results in a visual format that is immediately understandable, eliminating the need to interpret technical terms like center-of-gravity line while maintaining measurement precision through the underlying analysis system.
2Measurement precision
If detailed measurement data is presented in technical formats, then measurement precision is improved, but loss of information increases because the intended audience cannot interpret the data
Solution Approach 1:
The patent introduces an image processing system as an intermediary that translates precise measurement data into visual representations overlaid on video images. This intermediary converts technical posture evaluation data into intuitive visual cues that non-expert users can understand, preventing information loss by bridging the gap between precise measurement and human interpretation.
3Measurement precision
If professional interpretation is required for posture evaluation results, then measurement precision is improved, but device complexity increases because additional explanation systems are needed
Solution Approach 1:
The patent enables the system to self-serve by automatically generating and displaying intuitive visual feedback directly on the video image without requiring professional interpretation. The image processing system autonomously translates measurement data into understandable visual formats, eliminating the need for additional professional explanation systems while maintaining measurement precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to intuitively understand and correct their posture by visualizing evaluation indexes, making it easier for non-experts to improve their posture without needing professional explanations, as they can see the difference between their current and ideal postures in real-time.
Implementation Method 1
a half mirror; an imaging unit configured to be arranged behind the half mirror and image a subject present in front of the half mirror
Data Source
AI summary
A video image information processing apparatus includes a half mirror, an imaging unit arranged behind the half mirror for imaging a subject present in front of the half mirror, and a display unit that displays a video image in the half mirror. The video image information processing apparatus extracts a predetermined part of a human body from a video image of the subject captured by the imaging unit and performs measurement on the subject using information other than the video image. The video image information processing apparatus acquires evaluation information based on a result of the measurement performed by using information other than the video image and the position of the predetermined part of a human body. The video image information processing apparatus controls display by a display unit such that the acquired evaluation information is associated with the predetermined part in a mirror image in the half mirror.
