Network Models of Human-Machine Interaction

A simple framework is introduced for considering the elements of human-machine interaction. Use of this framework leads to consideration of network models of equipment; equipment and tasks; and equipment, tasks, and teams. Use of the resulting models as a basis for aiding and training personnel in complex systems is dicussed. Examples considered include display design for helicopter maintenance, intelligent interfaces for aircraft pilots and process control operators, and team training simulators for enhancing ship crew commuinications and coordination.
