Abstract:

A research program was undertaken to determine operator information processing capabilities for the type of display which is typical of computer-controlled systems. These displays require real-time surveillance by the operator so that, if necessary, he may override the computer at any point in time. This process has been referred to as active monitoring. The human monitor must maintain awareness of the displayed events and computer actions, in order to interact with the computer in a real-time fashion. One example of this type of system would be an airborne computer-controlled electronic countermeasures display. A part-task simulator for this type of display system was developed, and a study was designed to test active monitoring performance.
