In the field of human-machine systems, we research the interactions between a user and a technical system. From this, we develop methods on how human-machine interaction can be taken into account in user-centered product development. We focus in particular on technical systems in which the user is directly and continuously in flow of forces as well as flow of information. An example of such a technical system would be power tools. For this we develop methods for the acquisition and consideration of physical interaction between the system and user as well as methods to improve the subjective product perception. To illustrate these physical interactions, it is important to consider the active as well as passive characteristics of a human being. These include body stature, coupling forces or reaction forces, and effects of fatigue. Hence, we research physical human models, which are able to map the interaction between humans and a technical system with equivalent effects as well as to optimize a product with regard to user interaction. Furthermore, to improve subjective product perception and usability, we develop methods that support the developer in identifying and optimizing relevant design aspects. The research focus “human-machine systems” enables for the holistic development of technical systems under consideration of the user.

Definition of human-machine systems:

A human-machine system (MMS) is the targeted interaction between a human user and a technical system in order to effectively perform a given or self-selected human function through usage of the technical system (Johannsen 1993 and Timpe et al 2002).
