Motion Capture Analysis of Learning Effect for Assembly Tasks

The aging population has recently led to a labor shortage. Developing resources and transmitting skills to workers in the manufacturing industry is crucial to address these challenges. However, these skills must be conveyed through verbal instructions or on-the-job training from experienced workers to inexperienced ones. Thus, a quantitative analysis is required to understand their learning progress effectively. This study applies motion capture technology to visualize nut-tightening operations for gaining insights into the efficiency of workers and their proficiency levels, and assesses the skill development overtime by analyzing the time series of coordinate data.
