Information portrayal for decision support in dynamic intentional process environments
Wong, B L William; Sallis, Philip; O’Hare, David
This paper reports on preliminary findings of a cognitive task analysis conducted at an ambulance despatch control center. The intense and dynamic nature of the decision making environment is first described, and the decision process modelled in an attempt to identify decision strategies used by the Communications Officers. Some information portrayal requirements stemming from one of the decision processes are then discussed, and these requirements are then translated into a proposed display solution.
