Abstract

Designers of information retrieval systems are neglecting the unique relationship between an intermediary and the search system, be it a small microcomputer database system or larger systems such as OPACs or online database hosts. When designing user-friendly retrieval systems, a thorough knowledge of the interface of the machine as well as the nature and needs of the user is needed. For this purpose, 2 modles can be distinguished, namely, the mental model of the user and the conceptual model of the designer of the system. It is the task of the system designer to make these 2 models coincide. The conceptual model is the actual model of the retrieval systems as it is presented to the user by the designer of the system. The mental model is that model of the retrieval system through past experience with a particular or a number of systems. For this reason, experienced users may have a more clearly defined model of a specific system than the novice. The nature of the communication between man and machine is also explained, as well as a number of features of the interaction between the searcher and the computer. Specific hardware and software problems relating to man-machine interaction are discussed
