Abstract
This paper, the revision of an earlier report by the same author (issued by the Department of Computer Science, Tampere University, Finland), discusses difficulties in the design of manmachine systems, from the prespective of human-computer interaction. In particular, a current approach to complex systems, called 'cognitive engineering', is detailed and discussed in relation to problems of complexity and representation. Some of the conceptual insights of Jens Rasmussen are considered, in addition to other design responses, as means of making progress in the design of better man-machine systems. 1. Perspectives on HCI Following Rasmussen (Rasmussen, 1987; Rasmussen, 1988), we may distinguish three perspectives on human-computer interaction (HCI). The first of these concentrates on 'surface' characteristics of the interaction between computer system and user, seeking to optimise such interface features as response time, font size, display colours, shape and size of menus, icons, etc. (e....
