Human Cognition and Information Display in C3I System Tasks.

It is widely recognized that the growing demands of modern warfare strain and in some cases exceed human cognitive capabilities. Although modern command, control, communication, and intelligence (C3I) systems incorporate a number of advanced design concepts to reduce the burden on operators, it is essential that they retain certain key controlling functions. Therefore, efforts toward improving our understanding of how various design concepts affect how general design principles relate to the specific kinds of critical tasks performed by operators in C3I systems. The purpose of this report is to present a highly selective review of the literature on C3I tasks, display principles, and human information processing functions with an eye toward identifying promising variables or concepts for evaluation in a simulated system context.
