The digital factory with its innovative tools is experiencing an increasing importance, not only in experimental but also productive domains. One of these tools is the digital human model (DHM). In the field of production, the focus of using DHMs lies in the planning and evaluation of processes and products in terms of plausibility, productivity and ergonomics.

Up to now, ergonomic assessment within DHM simulations have been mostly limited to static evaluations of reachability and postures.

INTERACT is a running R&D project, working on the main weak points of DHM software tools. The industry-driven requirements are mainly the reduction of input effort, the increase of movement quality and a quick and intuitive way to create simulation variations in a workshop environment.

The utilization of sensor data to create high quality simulations is another point of development.

Next to the addressed improvement in productivity and plausibility, these latest advancements also enable automatic ergonomic assessments, including process oriented standards like EAWS, OCRA and NIOSH lifting index. The inclusion of these standards will allow a more holistic ergonomic assessment and therewith expand the fields of application in the industrial environment.

This paper will give an insight in the latest developments and the performance of current implementations of automatic ergonomic assessment within digital human models.
