Ergonomically Optimized Wearable Seating Posture Monitoring and Alert System for Mitigating Work-Related Musculoskeletal Disorders

Prolonged improper sitting posture is a significant contributor to Work-Related Musculoskeletal Disorders (WMSDs) and other health complications, particularly among students and office workers. This paper presents the design and development of a wearable posture monitoring and alerting system aimed at promoting better ergonomic habits and preventing the adverse effects of poor posture. The system leverages four Inertial Measurement Units (IMUs) strategically positioned on the body to detect angular deviations associated with improper posture. Using wireless communication through transmitter-receiver modules, the collected data is processed to provide real-time feedback and alerts, enabling users to self-correct their posture. Key features include the ability to monitor posture duration, filter involuntary movements, and deliver non-intrusive alerts to connected devices such as smartphones or computers. The proposed system not only enhances individual awareness of posture but also eliminates the need for external intervention, making it highly practical for diverse work and study environments. By integrating advancements in wearable technology, wireless data transmission, and real-time analytics, this system aims to contribute to the field of ergonomics and improve long-term health outcomes for its users.
