| Abstract: | The following article is the third of 3 articles that focus on user-centered design and usability in the field of industrial process control. Whereas the first article in this series (Burmester, Komischke, & Wust, this issue) dealt with usability engineering methods in the area of process control, this article explains the practical application of this procedure. To this end, a pilot project for the user-centered design of a user interface for a paper recycling plant is described here by way of example. Here a new layout based on users' mental models was systematically prepared. Extensive usability tests revealed that the design was understood and accepted both by users without any knowledge of the system (pupils at a paper technology college) and those with a knowledge of the system. |
