A Theoretical Basis for the Representation of On-Line Computer Systems to Naive Users
Article Abstract:
Computer system designers need to include the users of the system as part of overall design considerations. New techniques are needed to communicate to the user a conceptual model of the system being used. Terminal dialogues typically form the basis from which a naive user conceptualizes the system. Dialog design principles fail into three categories. First are those already established by use but without explicit theoretical justification. Second are those which seem intuitively correct but are not yet substantiated by theory. Third are those which are innovative and have arisen from research. An overview of current theory and practice is presented.

Cognitive Systems Engineering: New Wine in New Bottles
Article Abstract:
Typical man-machine systems have been designed to extend man's physical capabilities in processing data. Cognitive engineering systems are designed to extend man's mental, cognitive capabilities. A cognitive system adapts and modifies its actions using its knowledge of itself, its environment and its image of the user. An explanation of cognitive systems and how they progress from initial task to final evaluation is presented. Cognitive systems engineering can aid in the design of man-machine interfaces.
