Summary
This study introduces a Kinect-based game to correct poor posture in the elderly, helping maintain physical function and independence. The system achieved 95.20% detection accuracy in real-world tests.
Area of Science:
- Gerontology
- Biomedical Engineering
- Rehabilitation Technology
Background:
- Poor posture significantly impacts physical function and independence in the elderly.
- Maintaining physical activity and proper posture is crucial for healthy aging.
Purpose of the Study:
- To develop and evaluate a Kinect-based system for real-time posture correction in senior citizens.
- To integrate posture correction into an engaging game for physical stimulation and improved lifestyle.
Main Methods:
- The system utilizes Kinect sensor data to capture limb node information for real-time posture analysis.
- The Dynamic Time Warping (DTW) algorithm is employed to detect deviations from correct posture.
- A gamified application was developed to encourage physical activity and adherence to posture correction.
Main Results:
- The posture correction system demonstrated a high detection accuracy of 95.20%.
- Experimental testing in a nursing home setting confirmed the system's effectiveness with diverse users.
Conclusions:
- The proposed Kinect-based system effectively corrects poor posture in the elderly.
- The integrated game enhances physical stimulation and supports the maintenance of independence in later life.
