Ergonomic efforts aiming at compatibility in work design for realizing preventive occupational health and safety

Abstract Mutual adaptation and interchangeability of system elements are indispensible prerequisites for technical products. Similar to that technical compatibility, optimum design of a man—machine-system cannot be achieved without e.g. a compatible arrangement of connected displays and controls. Over and above those stimulus/ response relations, all technical components and interfaces have to be designed in such a way that they meet the capabilities of human beings in order to ensure the efficiency of work and exclude undesired impacts of work on the human being. 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. Examples of ergonomically designed working tools show that compatibility is capable of reducing the prevalence of occupational diseases and repetitive strain injuries as well as leading to lower physiological cost in such a way that the same output results from a lower demand of human resources, or even a higher performance will be attained. Compatibility also supports the quick perception and transmission of information in a man—machine-system, and as a result of lower requirements for decoding during information processing, spare mental capacity may enhance occupational safety. In the field of software, compatibility also helps to avoid psychological frustration.
