A graphical editor and process visualization system for man-machine interfaces of dynamic systems

Abstract

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.

Mensch-Maschine-Systeme

“…Anlehnung an DIN 66234/8 [1988]. Bildschirmoberfläche für die Phase der Ikonen-Generierung mit dem erzeugten Bildsymbol einer Pumpe in der Arbeitsfläche, umgeben von Menüs zur direkten Manipulation [ausFejes, Johannsen, Strätz, 1993].Menüs sind im Bild 11.23 nicht dargestellt worden. Hieraus wurde ein software-ergonomischer Leitfaden mit einer umfangreichen Prüffragenliste zur Bewertung entwickelt.…”

Design of intelligent human-machine interfaces

“…The latter dispose of three main subsystems, mainly the picture element generator, the picture generator and the process binding generator created through the process binding to dynamic variables of the technical system. The knowledge contained in the Generating Outputs functionality is represented in graphical objects and in related non-graphical information about the technical system [5]. Although a lot of research is currently achieved in the areas of speech output [6] and multi-media interfaces [7], the main mode or presentation is still the visualisation created with the dynamic graphical editors.…”
