N2 - An understanding of the level of physical workload experienced by an operator is important for designing workplace interventions that reduce injury risk. Existing methods for physical workload assessment can be disruptive to workers, are highly sensitive to the environment, and may not be feasible to implement in real-time on the manufacturing shop floor. The goal of this study was to investigate the potential of using changes in facial features as a method for real-time physical workload assessment. Four participants performed an assembly task during two sessions completed on different days, while measures of ratings of perceived exertion (RPE), performance and changes of facial features were collected. Results showed that facial features, such as head movement, left and right inner eyebrow point and bottom point of the lip had significant changes over time. Future work should investigate these changes further for the potential to assess physical workload in real-time onsite manufacturing.
