A Discrete Control Model of Operator Function: A Methodology for Information Display Design

Recent advances in computer technology and the changing rule of the human in complex systems require changes in design strategies for information displays. The use of discrete control models to represent the human operator´s cognitive and decisionmaking activities is described. The analytic procedures required to build a discrete control model show promise as a basis of a design methodology for the definition of an information display system for supervisory control tasks. The discrete control modeling procedures and their application for a simulated system is demonstrated.
