“…Software portability to different hardware and operating systems. Industrial needs as well as the requirement of a human-centred design approach can be considered by holding close contacts with the application domain and, particularly, by performing task and knowledge analyses as well as prototype evaluations of information presentations and picture manipulations with operators before and during the different design stages (Borys et al 1987;Johannsen 1990b). For the development of our graphical editor and our process-visualization system, this was partially done in the power-plant domain with the support of utility companies, a power-plant school, and the manufacturer in our project consortium.…”

The process visualization system of a manmachine interface is presented. It allows human operator(s) to interact with a dynamic technical system, here a thermal power plant. Also, a graphical editor for designing dynamic pictures of the process visualization system is explained. Both new systems have a common architecture and are based on the computer graphics standard PHIGS-2D with extensions for handling non-graphical and graphical information. The hierarchical information structures are manipulated with lists and pointers in a dynamic visual database. The two menu-driven interfaces for designers and for operators are described with their multi-window display layouts. The software of both systems is highly portable to different hardware and to other application domains.
