Since the first INTERACT Conference in September 1984, the field of Human-Computer Interaction has received increasing attention from researchers and industrial practitioners, the importance of the topic now being widely recognized. Technological developments have made it possible to seek new solutions to the problem of supporting work processes by information technology and for designing the interface between user and the machine. Computers have become an everyday and common tool in the work of many people. This has motivated the development of an interdisciplinary field of research, which now appears much more established than it was a few years ago.The INTERACT forums provide the opportunity for regular presentation and discussion of new results from research and application by bringing together the various disciplines and research approaches on a worldwide basis.

This work brings together papers written by researchers and practitioners actively working in the field of human-computer interaction. It should be of use to students who study information technology and computer sciences, and to professional designers who are interested in User Interface design.

Originally published in 1989 this title provided a comprehensive and authoritative introduction to the burgeoning discipline of human-computer interaction for students, academics, and those from industry who wished to know more about the subject. Assuming very little knowledge, the book provides an overview of the diverse research areas that were at the time only gradually building into a coherent and well-structured field. It aims to explain the underlying causes of the cognitive, social and organizational problems typically encountered when computer systems are introduced. It is clear and concise, whilst avoiding the oversimplification of important issues and ideas.

Discusses the application of formal methods - the attempt to provide methods that rigorously and unambiguously describe the behavior of a computer program or system - to the human computer interface.

This volume presents a selection of the contributions to the Seventh Workshop on Informatics and Psychology. The theme of the workshop was Visualization in Human-Computer Interaction. Visualization is nowadays recognized as an important aspect of user-oriented human-computer interfaces. Both informatics and psychology are concerned with this topic. In informatics, the technology is being developed which makes visualization and interaction based on visual concepts feasible. Another important trend in informatics is the development of prototypical solutions. Visual programming, visual languages, graphical interfaces, visual representations and many other keywords characterize current efforts in this field. Psychologists are working on the question of how people represent knowledge visually and how they can take advantage of visual representations when solving tasks.

This is the proceedings of the Sixth Symposium on Empirical Foundations of Information and Software Sciences (EFISS), which was held in Atlanta, Georgia, on October 19-21, 1988. The purpose of the symposia is to explore subjects and methods of scientific inquiry which are of common interest to information and software sciences, and to identify directions of research that would benefit from the mutual interaction of these two disciplines. The main theme of the sixth symposium was modeling in information and software engineering, with emphasis on methods and tools of modeling. The symposium covered topics such as models of individual and organizational users of information systems, methods of selecting appropriate types of models for a given type of users and a given type of tasks, deriving models from records of system usage, modeling system evolution, constructing user and task models for adaptive systems, and models of system architectures. This symposium was sponsored by the School of Information and Computer Science of the Georgia Institute of Technology and by the U.S. Army Institute for Research in Management Information, Communications, and Computer Sciences (AIRMICS). 17le Editors vii CONTENTS 1 I.
