Abstract
This paper describes a project to design and test a large wall-mounted group view display intended to support situation awareness of individuals and multi-person teams in an advanced power plant control room. The design process began with an analysis of the requirements for situation awareness of individuals and teams to establish the design basis. A function-based cognitive task analysis was then used to define the plant state information to be included in the group view display. A phased test program was then initiated to establish the adequacy of the design concept. The first study employed sequences of static displays representing “snapshots” of evolving normal and emergency events. The second study tested dynamic group view displays (three 100 inch wall mounted displays) driven by a high-fidelity plant simulation. The study compared operator performance with the function-based group view display to operator performance using a more traditional physical mimic overview display. Dependent measures included (1) objective measures of performance, (2) operator ratings of the displays, and (3) workload measures. The measures provided statistically significant, converging evidence of the superiority of the function-based group view display. The implication of the results for design of group view displays to support individuals and teams are discussed.
