Single Camera Human Movement Analysis System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clinical methods for analyzing human movement are largely subjective and lack an objective, quantified framework, leading to significant variations in results due to the level of experience and training of physicians, and are limited by the reliance on visual observation rather than objective measurement.
Innovation Solution
A system and method for comprehensive human movement analysis using a single camera with progressive scan capabilities, coupled with a computing device, which configures and controls camera settings, provides audio instructions, and applies analysis algorithms to recorded video and audio data to objectively measure human movement, allowing for comparison to normative standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual observation methods are used for human movement analysis, then the examination process is simple and accessible, but the measurement precision and objectivity are insufficient
Solution Approach 1:
The patent replaces the mechanical/visual observation system with an optical recording and computational analysis system. A camera records patient movements, and computer algorithms automatically analyze the video data to extract movement parameters, substituting subjective visual assessment with objective computational measurement.
Solution Approach 2:
The patent introduces video recording as an intermediary between the patient's movement and the analysis. Instead of direct visual observation, the movement is captured on video, which then serves as the basis for automated computational analysis, enabling precise and repeatable measurements.
2Measurement precision
If multiple cameras are used to improve measurement accuracy, then the measurement precision increases, but the device complexity and cost increase
Solution Approach 1:
The patent makes a single camera perform multiple functions by strategically positioning it to capture various movement planes and angles. The same camera records different types of movements (hand, foot, head, trunk) by adjusting patient positioning and camera parameters, eliminating the need for multiple specialized cameras.
Solution Approach 2:
The patent achieves different measurement perspectives by changing camera parameters (zoom, focus, orientation, pan, tilt, brightness, exposure) rather than adding multiple cameras. The system adapts the single camera's parameters to suit different examination requirements.
3Reliability
If subjective clinical assessment is used, then the ease of operation is high, but the reliability and consistency of results vary based on physician experience
Solution Approach 1:
The system provides automated feedback by comparing measured movement parameters against normative data and generating objective diagnostic reports. This eliminates variability in clinical judgment while maintaining ease of use through automated analysis and interpretation.
Solution Approach 2:
The system performs self-analysis by automatically processing video recordings through computational algorithms that extract movement parameters, compare them to norms, and generate diagnostic conclusions without requiring expert manual interpretation, ensuring consistent results.
