Investigating the Use of Changes in Facial Features as Indicators of Physical Workload.

Abstract

OCCUPATIONAL APPLICATIONSPhysical workload may lead to negative outcomes, including musculoskeletal disorders. In this study, we found that there were observable changes in facial features over the length of a low intensity, prolonged assembly task, and that these changes were correlated to other measures of physical workload. This method can be implemented by practitioners to evaluate physical workload.
