ME-WARD is designed to process joint angle data from motion capture systems, includinginertial measurement unit (IMU)-based setups, and deep learning human body pose tracking models. The tool’sflexibility enables ergonomic risk assessment using any system capable of reliably measuring joint angles,extending the applicability of RULA beyond proprietary setups. To validate its performance, the tool was testedin an industrial setting during the assembly of conveyor belts, which involved high-risk tasks such as insertingrods and pushing conveyor belt components. The experiments leveraged gold standard IMU systems alongside astate-of-the-art monocular 3D pose estimation system. The results confirmed that ME-WARD produces reliableRULA scores that closely align with IMU-derived metrics for flexion-dominated movements and comparableperformance with the monocular system, despite limitations in tracking lateral and rotational motions. This workhighlights the potential of integrating multiple motion capture technologies into a unified and accessible ergo-nomic assessment pipeline. By supporting diverse input sources, including low-cost video-based systems, theproposed multimodal approach offers a scalable, cost-effective solution for ergonomic assessments, paving theway for broader adoption in resource-constrained industrial environments.
