Design of information systems, on the one hand, is often dominated by pure technical considerations of performance, correctness or reliability. On the other hand, sociological analysis of the social impact of information technology is not transfered to operationalised design criteria and to practice. The paper discusses this contradiction and tries to overcome the gap between computer science and social sciences in design by analysing the history of design in architecture and fine arts as well as the approaches of contemporary design-oriented disciplines. Based on this analysis and on the broad discussion about human-centredness, foundations of a new Design Science are outlined. Consequences for the education of computer scientists and software designers are discussed.

As pressures on the service economy from globalisation increase, new techniques may be appropriate for designing service systems. This paper examines the tradition of service quality and argues that its unique characteristics, such as the joint production of offerings by operators and customers, could benefit from the techniques of human factors. The interaction between human factors and quality is reviewed and four issues are extracted that should be directly applicable to service encounters. These are interface design, the understanding of error causation, a design for operator well-being and human/automation function allocation. A framework is proposed for considering technology explicitly in the design of service systems.

This chapter presents an overview of several recent developments in vision science, and outlines some of their implications for the management of visual attention in graphic displays. These include ways of sending attention to the right item at the right time, techniques to improve attentional efficiency, and possibilities for offloading some of the processing typically done by attention onto nonattentional mechanisms. In addition it is argued that such techniques not only allow more effective use to be made of visual attention, but also open up new possibilities for human-machine interaction.

Human-computer interaction today has got a touch of magic: Without understanding the causal coherence, using a computer seems to become the art to use the right spell with the mouse as the magic wand — the sorcerer's staff. Goethes's poem admits an allegoric interpretation. We explicate the analogy between using a computer and casting a spell with emphasis on teaching magic skills. The art to create an ergonomic user interface has to take care of various levels of skills for the human operators. The problem of logical discontinuities as opposed to continuous control is the most serious obstacle for human-computer interaction.

This paper analyzes epistemological and ontological dimensions of Human-Computer Interaction (HCI) through an analysis of the functions of computer systems in relation to their users. It is argued that the primary relation between humans and computer systems has historically been epistemic: computers are used as information-processing and problem-solving tools that extend human cognition, thereby creating hybrid cognitive systems consisting of a human processor and an artificial processor that process information in tandem. In this role, computer systems extend human cognition. Next, it is argued that in recent years, the epistemic relation between humans and computers has been supplemented by an ontic relation. Current computer systems are able to simulate virtual and social environments that extend the interactive possibilities found in the physical environment. This type of relationship is primarily ontic, and extends to objects and places that have a virtual ontology. Increasingly, computers are not just information devices, but portals to worlds that we inhabit. The aforementioned epistemic and ontic relationships are unique to information technology and distinguish human-computer relationships from other human-technology relationships.

In this paper we review some problems with traditional approaches for acquiring and representing knowledge in the context of developing user interfaces. Methodological implications for knowledge engineering and for human-computer interaction are studied. It turns out that in order to achieve the goal of developing human-oriented (in contrast to technology-oriented) human-computer interfaces developers have to develop sound knowledge of the structure and the representational dynamics of the cognitive system which is interacting with the computer.We show that in a first step it is necessary to study and investigate the different levels and forms of representation that are involved in the interaction processes between computers and human cognitive systems. Only if designers have achieved some understanding about these representational mechanisms, user interfaces enabling individual experiences and skill development can be designed. In this paper we review mechanisms and processes for knowledge representation on a conceptual, epistemological, and methodologieal level, and sketch some ways out of the identified dilemmas for cognitive modeling in the domain of human-computer interaction.

Currently there is a clear trend towards questioning the traditional sovereign human self which for two hundred years has had an undisputed central status within European culture and philosophy. This challenges the tradition of anthropocentrism which in a Scandinavian computer science context has had two theoretical foundations: the workoriented design theory represented by the Scandinavian participatory design philosophy, and the idea of the computer to a rather passive medium for human communication. The process, reducing the computer to a rather passive medium for human communication. The paper firstly examines these two theoretical anthropocentric positions. Secondly it outlines the trend towards challenging the status of the human self within different research contexts. This trend represents a challenge for Human-centred systems design. Finally, it discusses the new demands for conceptualising basic IT research phenomena created by this development, with particular focus on the issue of human-centredness as a systems design strategy.

Visual analytics is a new interdisciplinary field of study that calls for a more structured scientific approach to understanding the effects of interaction with complex graphical displays on human cognitive processes. Its primary goal is to support the design and evaluation of graphical information systems that better support cognitive processes in areas as diverse as scientific research and emergency management. The methodologies that make up this new field are as yet ill defined. This paper proposes a pathway for development of visual analytics as a translational cognitive science that bridges fundamental research in human/computer cognitive systems and design and evaluation of information systems in situ. Achieving this goal will require the development of enhanced field methods for conceptual decomposition of human/computer cognitive systems that maps onto laboratory studies, and improved methods for conducting laboratory investigations that might better map onto real-world cognitive processes in technology-rich environments.
