This study reviews assessment methods in DHM tools and explore the utilization of these methods in industry. Interviews with DHM users and ergonomics specialists within the Swedish automotive industry showed that simulations and following evaluations are almost solely based on static postures. Integrated evaluation tools in current DHM systems are seldom utilized; instead they use company specific evaluation methods. Both the review of current DHM tools and the interviews confirmed that there is an evident need for more time-dependant evaluation methods. The results are used to present a conceptual DHM module dealing with time-dependant ergonomics assessment.
