Johnson, Christopher W. – Human-Computer Interaction, 1996
The development of safety-critical systems (aircraft cockpits and reactor control rooms) is qualitatively different from that of other interactive systems. These differences impose burdens on design teams that must ensure the development of human-machine interfaces. Analyzes strengths and weaknesses of formal methods for the design of user…

Bellotti, Victoria; And Others – Human-Computer Interaction, 1996
Describes a collection of systematic theory-based analyses of a system prototype that inherited its control mechanisms from preexisting systems. Demonstrates that collective use of system and user modeling techniques provides insight into a complex design problem, enabling the examination of design decisions for users and implementation. Discusses…

Gray, Wayne D.; Salzman, Marilyn C. – Human-Computer Interaction, 1998
The design of five experiments comparing usability evaluation methods (UEMs) is examined. Each has had an important influence on human-computer interaction (HCI); however, problems with experimental design raised questions as to the efficacy of various UEMs. To obtain desired outcomes of the experimental method addressing HCI issues, close…

Brown, John Seely; Duguid, Paul – Human-Computer Interaction, 1994
Argues that the shared use of artifacts is supported by latent border resources that lie beyond the canonical artifact. Designers must understand the role border resources play and work more directly to help users develop them. This will require designers to change their understanding of artifacts and users. (Contains 69 references.) (KRN)

Moran, Thomas P., Ed.; And Others – Human-Computer Interaction, 1985
Individual papers discussing various facets of human relationships with interactive computer systems present an analysis of direct manipulation interfaces; discuss notion of conceptual models shared by system and user and propose a design methodology for delivering models to users; and address the intelligibility of systems and importance of…

Christel, Michael G. – Human-Computer Interaction, 1994
Describes an experiment that was conducted using a digital video course to determine the effects of multimedia interface capabilities on computer-assisted instruction, particularly on recall performance and attitude. Results are reported that indicate motion video is more effective than slides, and design guidelines are suggested. (34 references)…
