Detection of physical strain and fatigue in industrial environments using visual and non-visual sensors.

sustAGE is an ongoing project, developing an Internet of Things ecosystem, including smartphones, smartwatches, localization and environmental sensors and cameras to support ageing workers in industrial environments while performing assembly tasks, such a car manufacturing factory. In this context, we briefly describe a non-obtrusive method for assessing the physical strain of workers using visual data and a method for detecting worker fatigue using heart rate data acquired by smartwatches. The results of both methods are utilized by the recommendation system developed in sustAGE to support preventive actions towards work-related musculo-skeletal disorders and fatigue and to promote occupational safety.
