Visualizing complex processes on large screen displays: Design principles based on the Information Rich Design concept

This paper describes recent design modifications where new functionality is integrated into existing graphical objects, keeping the original simplicity. This paper proposes design principles for large screen displays based on theoretical discussions of Situation Awareness and a user test using crews of certified operators. The user test shows positive results on pattern recognition of process data and a newly developed animation of unacknowledged alarms; however, the concept still suffers from colour and readability issues.
