Compatibility as guiding principle for ergonomics work design and preventive occupational health and safety

Helmut Strasser
2021 Zeitschrift für Arbeitswissenschaft  
Compatibility between the properties of the human organism on the one hand, and the adaptable technical components of a work system on the other hand, offers a great potential of preventive measures.  ...  Besides presenting examples of work design according to the principle of compatibility, also methods will be shown which enable the assessment of the ergonomic quality of hand-held tools and computer input  ...  on the design of his workplace with the connected sensory and motoric interfaces, the overall system performance of such a man-machine system is determined by the quality of the total ergonomic layout  ...
