Ergonomical principals of modern information representation on display devices and consequences for the application in nuclear power plant control rooms. Vol. 1

The project is divided into three phases. In a first phase, an enquiry of the actual state of modern information representation and of the situation in nuclear power plants has been performed together with an analysis of the relevant literature. On this basis preliminary recommendations were formulated. These recommendations, together with the analysis of a system, were the basis of the design of the first symbolic representations on the VDU. These representations were designed by means of a specially developed program. In a second phase, these exemplary representations were corrected using the recommendations. In that way, new representations were created and completeness and applicability of the recommendations were verified. In a future, third phase certain recommendations will be checked empirically. The result of the study is a catalogue that contains recommendations for certain variables (e.g.: Colour, organisation of the material, coding alphabet etc.) depending on the tasks of the operators (detection, discrimination, identification, decoding etc.). It is shown, which performance of the operator is influenced by which variable. (orig./GL)
