    This study introduces an automatic, privacy-preserving method using stereo cameras and deep learning to analyze elderly gait. The system accurately measures gait features like step length and walking speed in daily environments.

    Area of Science:

    • Gerontology
    • Biomedical Engineering
    • Computer Vision

    Background:

    • Gait analysis is crucial for assessing elderly health status, with abnormalities indicating potential health risks.
    • Current gait assessment methods like Timed Up and Go (TUG) and Performance Oriented Mobility Assessment (POMA) are often complex and require clinical settings.
    • There is a growing demand for automated, accurate, and non-intrusive gait measurement solutions for home and nursing facility environments.

    Purpose of the Study:

    • To develop an automatic and privacy-conscious system for gait analysis using non-contact stereo cameras.
    • To leverage deep learning and 3D sensing for precise measurement of gait parameters such as step length and walking speed.
    • To validate the system's accuracy and robustness in real-world settings for elderly care.
