Towards a human eye behavior model by applying Data Mining Techniques on Gaze Information from IEC

In this paper, we firstly present what is Interactive Evolutionary Computation (IEC) and rapidly how we have combined this artificial intelligence technique with an eye-tracker for visual optimization. Next, in order to correctly parameterize our application, we present results from applying data mining techniques on gaze information coming from experiments conducted on about 80 human individuals

Scaling Participation -- What Does the Concept of Managed Communities Offer for Participatory Design?

This paper investigates mechanisms for scaling participation in participatory design (PD). Specifically, the paper focuses on managed communities, one strategy of generification work. We first give a brief introduction on the issue of scaling in PD, followed by exploring the strategy of managed communities in PD. This exploration is underlined by an ongoing case study in the healthcare sector, and we propose solutions to observed challenges. The paper ends with a critical reflection on the possibilities managed communities offer for PD. Managed communities have much to offer beyond mere generification work for large-scale information systems, but we need to pay attention to core PD values that are in danger of being sidelined in the process

Iterative criteria-based approach to engineering the requirements of software development methodologies

Software engineering endeavours are typically based on and governed by the requirements of the target software; requirements identification is therefore an integral part of software development methodologies. Similarly, engineering a software development methodology (SDM) involves the identification of the requirements of the target methodology. Methodology engineering approaches pay special attention to this issue; however, they make little use of existing methodologies as sources of insight into methodology requirements. The authors propose an iterative method for eliciting and specifying the requirements of a SDM using existing methodologies as supplementary resources. The method is performed as the analysis phase of a methodology engineering process aimed at the ultimate design and implementation of a target methodology. An initial set of requirements is first identified through analysing the characteristics of the development situation at hand and/or via delineating the general features desirable in the target methodology. These initial requirements are used as evaluation criteria; refined through iterative application to a select set of relevant methodologies. The finalised criteria highlight the qualities that the target methodology is expected to possess, and are therefore used as a basis for de. ning the final set of requirements. In an example, the authors demonstrate how the proposed elicitation process can be used for identifying the requirements of a general object-oriented SDM. Owing to its basis in knowledge gained from existing methodologies and practices, the proposed method can help methodology engineers produce a set of requirements that is not only more complete in span, but also more concrete and rigorous

Cultures of Sustainability: ‘Ways of doing’ cooking

In our research, we have been expanding our conceptual and methodological frames of reference as designers, in order to explore the complexity of factors involved in environmental sustainability and the consequent challenges posed for design research. In this paper, we discuss some of these issues in user-centered and sustainable design, drawing out and developing relations to concepts from other fields of study, such as the sociology of consumption and material culture. In order to better understand the role that (sustainable) design products might play within people’s everyday lives and lifestyles, we interpret and discuss notions of ‘socio-cultural practices’ of consumption and frame an approach to studying people’s ‘ways of doing’ with artifacts. We point to two examples from our previous research on designing for energy awareness and for sustainable bathing practices. A current study is presented in depth, in which families and singles, resident in The Netherlands but originating from different countries, have been observed and interviewed during preparation of a meal, eating and clearing up afterwards. Through studying and reflecting on the different ‘ways of doing’ cooking, we gained insights into how cooking and a range of associated practices and artifacts are deeply embedded in traditions, meanings and aspirations. Issues of environmental consumption, such as water, energy and waste, are at stake in such design research but, as we argue, so is attention and sensitivity to how these are interwoven in meaningful socio-cultural practices. The setup and findings are presented, as a point of departure for raising conceptual and methodological questions to be developed in future work

Libraries in transition: evolving the information ecology of the Learning Commons: a sabbatical report

This sabbatical report studied various models in order to determine best practices for design, implementation and service of Leaning Commons, a library service model which functionally and spatially integrates library services, information technology services, and media services to provide a continuum of services to the user

What Are We Doing with the Website: Transition, Templates, and User Experience in One Special Collections Library

[Excerpt] At the Eberly Family Special Collections Library (SCL), we have found that our website is often the first place a researcher will look to learn about our repository. Our online web presence is a business card, our chance to make a positive first impression. While our library, among others, has devoted time and resources to the development of new access tools and discovery layers, we have learned that our online presence also needs updates, revisions, and improvements. New tools and access points are valuable, but we can also improve existing tools even as we look forward to new developments in access and discovery. Through conscious efforts to include end users’ feedback in our website design decisions, we create more effective online tools. Our website is a crucial component of our efforts to direct users to our collections, and to publicize our services and programs. In this same vein, our end users can contribute to this design partnership through dedicated user experience testing. The SCL experimented with collaborative decision-making with its website committee, as well as with user experience testing in order to support our requests for additional web development work from the Libraries’ Information Technology department (I-Tech). Through this process, our library gained a more holistic understanding of the needs of online special collections and archives users; we also learned how to communicate more effectively between the department who worked with end users (SCL) and the department performing the actual web development work (I-Tech). While development work was limited to working within the mandatory web template, our user experience testing and the efforts of our internal website committee resulted in a better online experience for our stakeholders, based on the feedback we received from usability testing. Although our website is always a work in progress, we feel that we were able to develop practical ways to adjust to a website migration within in a dispersed and hierarchical information technology environment
