This article presents a critical review of patterns and pattern languages in hu-man–computer interaction (HCI). In recent years, patterns and pattern languages have received considerable attention in HCI for their potential as a means for developing and communicating information and knowledge to support good design. This review examines the background to(More)
BACKGROUND Although most aspects of the consultation have been extensively reported there is very little information on the effects of interruptions on the consultation. OBJECTIVE We wished to discover the patients' view of interruptions. METHODS In this pilot study the sources and frequency of interruptions to the consultations of a single general(More)
In this paper, we describe an approach to allocation of function that makes use of scenarios as its basic unit of analysis. Our use of scenarios is driven by a desire to ensure that allocation decisions are sensitive to the context in which the system will be used and by insights from economic utility theory. We use the scenarios to focus the attention of(More)
This workshop explores User Centered Design (UCD) challenges and contributions to International economic and community Development. We are addressing interaction design for parts of the world that are often marginalized by the Global North as well as people in the Global North who are themselves similarly marginalized by poverty or other barriers. We hope(More)
Ambulance control involves distributed group work using a mix of computer and communications technologies. The implementation of computer technologies has had mixed results in this area, evidenced by serious failures in the London Ambulance Service in 1992. Often failures are due to inadequate attention to integration of organisational and technical aspects(More)
This paper considers some of the ethical questions that arise in conducting interventionist ICTD research, and examines the ethical advice and guidance that is readily available to researchers. Recent years have seen a growing interest from technology researchers in applying their skills to address the needs and aspirations of people in developing regions.(More)
Much of the work reported in the first three DSVIS conferences has concentrated on techniques and languages for specifying and developing interactive systems. In this paper, we argue that a change of emphasis may be necessary as the field matures. We argue that real projects with specific objectives for formal methods are more likely to employ a range of(More)
We describe a patient with relapsing polychondritis who developed fatal cardiac involvement comprising complete heart block, acute aortic incompetence, and cardiovascular collapse. Pathologic studies showed fibrosis of the cardiac conducting system and necrotizing inflammation of the aortic valve, features not previously described in relapsing(More)
