Meta-design theory emphasizes that system designers can never anticipate all future uses of their system at design time, when systems are being developed. Rather, end users shape their environments in response to emerging needs at use time. Meta-design theory suggests that systems should therefore be designed to adapt to future conditions in the…

Redesign of human-computer interface for users of computerized information systems can make substantial difference in training time, performance speed, error rates, and user satisfaction. Information and computer scientists are using controlled psychologically oriented experimentation, and evaluations during system development and active use to…

A simulation system capable of supporting human factors experiments in the development of military training devices is described. The first phase of the study consisted of (1) a review of tasks performed by the operators of different types of military simulation systems, (2) an analysis of problems experienced in the development of devices for…
