    This is the post-print version of the published chapter. The original publication is available at the link below. Copyright @ 2010 IFIP International Federation for Information Processing.The role of Open Source Software (OSS) in the e-learning business has become more and more fundamental in the last 10 years, as long as corporate and government organizations have developed their educational and training programs based on OSS out-of-the-box tools. This paper qualitatively documents the decision of the largest UK e-learning provider, the Open University, to adopt the Moodle e-learning system, and how it has been successfully deployed in its site after a multi-million investment. A further quantitative study also provides evidence of how a commercial stakeholder has been engaged with, and produced outputs for, the Moodle community. Lessons learned from this experience by the stakeholders include the crucial factors of contributing to the OSS community, and adapting to an evolving technology. It also becomes evident how commercial partners helped this OSS system to achieve the transition from an “average” OSS system to a successful multi-site, collaborative and community-based OSS project

    On the perceptual aesthetics of interactive objects

    In this paper we measured the aesthetics of interactive objects (IOs), which are three-dimensional physical artefacts that exhibit autonomous behaviour when ‎handled. The aim of the research was threefold: firstly, to investigate whether aesthetic preference for distinctive objects' structures emerges in compound stimulation; secondly, to explore whether there exists aesthetic preference for distinctive objects’ behaviours; and lastly, to test whether there exists aesthetic preference for specific combinations of objects' structures and behaviours. The following variables were systematically manipulated: 1) IOs’ contour (rounded vs. angular); 2) IOs’ size (small vs. large); 3) IOs’ surface texture (rough vs. smooth); and 4) IOs’ behaviour (Lighting, Sounding, Vibrating, and Quiescent). Results show that behaviour was the dominant factor: it influenced aesthetics more than any other characteristic; Vibrating IOs were preferred over Lighting and Sounding IOs, supporting the importance of haptic processing in aesthetics. Results did not confirm the size and smoothness effects previously reported in vision and touch respectively, which suggests that for the aesthetics preference that emerges in isolated conditions may be different in compound stimulation. Finally, results corroborate the smooth curvature effect

    How technology can impact customer-facing train crew experiences?

    Customer-facing train crew have to follow strict procedures to guarantee that trains are safe and run on time. They are also responsible for revenue protection and customer care. Human factors and ergonomics research are instrumental to understand the safety-critical aspects and improve work. We bring user experience research and personas to describe how train crew perceive their routines and how new technology may impact them. We conducted seven hours of interviews and 30 hours of shadowing observations with train crew (n = 22) to provide an understanding of who are they and to define their experiences. We present crew’s current routines and created two personas to represent them. One is slightly reluctant to adopt the proposed technology, whereas the other is more accepting. Results indicate how such technology may affect crew work ergonomics and experiences, and suggest which valuable aspects should be maintained, for example the positive interactions with passengers

    Futures in the making: Practices to anticipate 'ubiquitous computing'

    Get PDF
    This paper addresses the discourse for a proactive thinking of futurity, intimately concerned with technology, which comes to an influential fruition in the discussion and representation of 'ubiquitous computing'. The imagination, proposal, or playing out of ubiquitous computing environments are bound up with particular ways of constructing futurity. This paper charts the techniques used in ubiquitous computing development to negotiate that futurity. In so doing, it engages with recent geographical debates around anticipation and futurity. The discussion accordingly proceeds in four parts. First, the spatial imagination engendered by the development of ubiquitous computing is explored. Second, particular techniques in ubiquitous computing research and development for anticipating future technology use, and their limits, are discussed through empirical findings. Third, anticipatory knowledge is explored as the basis for stable means of future orientation, which both generates and derives from the techniques for anticipating futures. Fourth, the importance of studying future orientation is situated in relation to the somewhat contradictory nature of anticipatory knowledges of ubicomp and related forms of spatial imagination. © 2012 Pion and its Licensors

    Learners in a Changing Learning Landscape: Reflections from an Instructional Design Perspective

    Van Merriënboer, J. J. G., & Stoyanov, S. (2008). Learners in a changing learning landscape: Reflections from an instructional design perspective. In J. Visser & M. Visser-Valfrey (Eds.), Learners in a changing learning landscape: Reflections from a dialogue on new roles and expectations (pp. 69-90). Dordrecht, The Netherlands: Springer.Both learners and teachers find themselves in a learning landscape that is rapidly changing, along with fast societal and technological developments. This paper discusses the new learning landscape from an instructional design perspective. First, with regard to what is learned, people more than ever need flexible problem-solving and reasoning skills allowing them to deal with new, unfamiliar problem situations in their professional and everyday life. Second, with regard to the context in which learning takes place, learning in technology-rich, informal and professional 24/7 settings is becoming general practice. And third, with regard to the learners themselves, they can more often be characterized as lifelong learners who are mature, bring relevant prior knowledge, and have very heterogeneous expectations and perceptions of learning. High-quality instructional design research should focus on the question which instructional methods and media-method combinations are effective, efficient and appealing in this new learning landscape. Some innovative instructional methods that meet this requirement are discussed

    Transitions in Human Computer Interaction: From Data Embodiment to Experience Capitalism

    This article develops a critical theory of human–computer interaction (critical HCI) intended to test some of the assumptions and omissions made in the field as it transitions from a cognitive theoretical frame to a phenomenological understanding of user experience described by Harrison et al. (the three paradigms of HCI. Paper presented at the Conference on human factors in computing systems. https://people.cs.vt.edu/~srh/Downloads/TheThreeParadigmsofHCI.pdf, 2007) as a third research paradigm and similarly Bþdker (when second wave HCI meets third-wave challenges. In: NordiCHI ‘06 Proceedings of the 4th Nordic conference on human–computer interaction: changing roles, 1–8. http://dl.acm.org/citation.cfm?id=1182476; 2006, Interactions 22(5):24–31; Bþdker, Interactions 22(5)):24–31, 2015) as third-wave HCI. Although this particular focus on experience has provided some novel avenues of academic enquiry, this article draws attention to a distinct bridge between the conventional HCI disciplinary concerns with predominantly task-based digital work and use context and a growing business interest in consumer experiences in digital environments. Critical HCI addresses the problem of experience in two interrelated ways. On one hand, it explores the role market logic plays in putting user experiences to work. On the other hand, it engages with ontological understandings of experience hitherto realized in HCI by way of a phenomenological matrix (Harrison et al. The three paradigms of HCI. Paper presented at the Conference on human factors in computing systems. https://people.cs.vt.edu/~srh/Downloads/TheThreeParadigmsofHCI.pdf, 2007). The article concludes by bringing in an old thinker (A. N. Whitehead) to consider experience in novel ways that relate ontological concerns to a broader political concept of experience capitalism

    Scenario Analysis as a Tool for Informing the Design of Behaviour Change Interventions

    Get PDF
    This article presents the design process behind the specification of a behaviour change intervention method to promote energy saving. The amount of energy used for food preparation is highly influenced by people’s behaviours. A user-centred design approach based on scenario analysis was applied to provide understanding of context of use and specification of user requirements. This knowledge was applied to the design of behaviour change interventions to motivate sustainable behaviours

    Fluid challenges in intensive care: the FENICE study A global inception cohort study

    Get PDF
    Fluid challenges (FCs) are one of the most commonly used therapies in critically ill patients and represent the cornerstone of hemodynamic management in intensive care units. There are clear benefits and harms from fluid therapy. Limited data on the indication, type, amount and rate of an FC in critically ill patients exist in the literature. The primary aim was to evaluate how physicians conduct FCs in terms of type, volume, and rate of given fluid; the secondary aim was to evaluate variables used to trigger an FC and to compare the proportion of patients receiving further fluid administration based on the response to the FC.This was an observational study conducted in ICUs around the world. Each participating unit entered a maximum of 20 patients with one FC.2213 patients were enrolled and analyzed in the study. The median [interquartile range] amount of fluid given during an FC was 500 ml (500-1000). The median time was 24 min (40-60 min), and the median rate of FC was 1000 [500-1333] ml/h. The main indication for FC was hypotension in 1211 (59 %, CI 57-61 %). In 43 % (CI 41-45 %) of the cases no hemodynamic variable was used. Static markers of preload were used in 785 of 2213 cases (36 %, CI 34-37 %). Dynamic indices of preload responsiveness were used in 483 of 2213 cases (22 %, CI 20-24 %). No safety variable for the FC was used in 72 % (CI 70-74 %) of the cases. There was no statistically significant difference in the proportion of patients who received further fluids after the FC between those with a positive, with an uncertain or with a negatively judged response.The current practice and evaluation of FC in critically ill patients are highly variable. Prediction of fluid responsiveness is not used routinely, safety limits are rarely used, and information from previous failed FCs is not always taken into account
