The usability of any computer system is determined to a large degree by the reactions of users to that system. Both the interface to the system and the system itself determine these reactions. The difficulty for the interface designer stems from the necessity of integrating the physical features of the system with the psychological features of the human user. This paper considers both the psychological and the computer science philosophies of human-computer interface design. In addition, throughout the paper, the need for a user-centered design philosophy is stressed. An expert system for conceptual bridge design is described, which, although refined at the functional level, fails at the level of human-computer dialogue. We present arguments and data to show how a user-centred design philosophy can enhance the utility of such a system.
