Arrangementet er afholdt A visit to the 'New Utopia' - Revitalizing democracy, emancipation and quality in co-operative design 25 years ago co-operative design started out as a result of technological immersion in workplace settings. The co-operative design approach propagated how ideals as democracy, emancipation and quality were essential when designing technology for workplaces. Today, technology is spread into domestic and non-professional practices. Even though time has changed over the past 25 years, this paper argues for revitalization of the 'Utopian' ideals when designing technology for everyday use. By addressing the original 'Utopian' ideals in the light of the new challenges for co-operative design, this paper voices the need for democracy, emancipation and quality when designing technology for non-professional used. The paper discusses the ideals in three current design projects. Evidence-based development: A viable approach? (short paper) Systems development is replete with projects that represent substantial resource investments but result in systems that fail to meet users' needs. Evidence-based development is an emerging idea intended to provide means for managing customer-vendor relationships and working systematically toward meeting customer needs. We are suggesting that the effects of the use of a system should play a prominent role in the contractual definition of IT projects and that contract fulfillment should be determined on the basis of evidence of these effects. Based on two ongoing studies of home-care management and electronic patient records for diabetes patients, this paper reports research in progress regarding the prospects and pitfalls of evidence-based development. HyperFloor (short paper) This paper presents the vision of the HyperFloor, a local positioning system offering the possibility of local positioning of staff, personnel, visitors, patients and equipment in a hospital environment. The HyperFloor vision is based on camera recognition of floor patterns with a correspondence through wireless networks to a database. The HyperFloor offers a robust supplement to other local positioning systems and can be used by networked camera based devices used by patients or brought by visitors. Criticism as an approach to interface aesthetics In this paper we discuss the re-orientation of human-computer interaction as an aesthetic field. We argue that mainstream approaches lack of general openness and ability to assess experience aspects of interaction, but that this can indeed by remedied. We introduces the concept of interface criticism as a way to turn the conceptual re-orientation in to handles for practical design, and we present and discuss an interface criticism guide. Two psychology-based usability inspection techniques studied in a diary experiment Inspection techniques are widely used during systems design as a supplement to empirical evaluations of usability. Psychology-based inspection techniques could give important insights into how thinking shapes interaction, yet most inspection technique do not explicitly consider users' thinking. We present an experiment comparing tow psychology-based inspection techniques, cognitive walkthrough (CW) and metaphors of human thinking (MOT). Twenty participants evaluated web sites for e-commerce while keeping diaries of insights and problems experienced with the techniques. Using MOT, participants identified 30¤ more usability problems and in a reference collection of problems achieved a broader coverage. Participants preferred using the metaphors, finding them broader in scope. An analysis of the diaries shows that participants find it hard to understand MOT, while CW limits the scope of their search for usability problems. Participants identified problems in many ways, not only through the techniques, reflecting large differences in individual working styles. Sharing and learning through pair writing of scenarios (short talk) This paper describes the results of an empirical study consisting of five sessions where scenarios are written by two writes working in unison, for instance a usability specialist and a software develop, making it possible for them to explore and reach a common understanding of requirements and design ideas. This study demonstrates that it is possible to produce scenarios through Pair Writing and it gives examples of how two writers can inspired, adjust and learn from each other through Pair Writing. Instant Data Analysis: Conducting Usability Evaluations in a Day When designing a usability evaluations, key decisions must be made regarding methods and techniques for data collection and analysis. Although there is a strong body of research within human-computer interaction regarding the appropriate choices of data collection methods and techniques, much less research has been conducted examining and comparing methods and techniques for analyzing the collected data. This paper presents a data analysis technique which allows usability evaluations to be conducted, analyzed and documented in a day; Instant Data Analysis (IDA). The use of this technique is exemplified through a usability evaluation of a software product for a large hospital for which traditional video data analysis and Instant Data Analysis were applied independently through a controlled experiment. Among our key findings, the experiment revealed that in only 10% of the time required to do the video data analysis, Instant Data Analysis identified 85% of critical usability problems in systems being evaluated. At the same time, the noise of unique usability problems usually characterizing video data analysis was significantly reduced. |
