A novel methodology for evaluating user interfaces in health care

A pilot study is reported to identify an improved method of evaluating digital user interfaces in health care. Experience and developments from the aviation industry and the NASA-TLX mental workload assessment tools are applied in conjunction with Nielsen heuristics for evaluating an Electronic Health Record System in an Irish hospital. The NASA-TLX performs subjective workload assessments on operators working with various human-computer systems. Results suggest that depending on the cognitive workload and the working context of users, the usability will differ for the same digital interface. We conclude that incorporating the NASA-TLX with Nielsen\u27s heuristics offers a more reliable method in design and evaluation of digital user interfaces in clinical environments, since the healthcare work context is taken into account. Improved interfaces can be expected to reduce medical errors and improve patient care

Human computer interaction for international development: past present and future

Recent years have seen a burgeoning interest in research into the use of information and communication technologies (ICTs) in the context of developing regions, particularly into how such ICTs might be appropriately designed to meet the unique user and infrastructural requirements that we encounter in these cross-cultural environments. This emerging field, known to some as HCI4D, is the product of a diverse set of origins. As such, it can often be difficult to navigate prior work, and/or to piece together a broad picture of what the field looks like as a whole. In this paper, we aim to contextualize HCI4D—to give it some historical background, to review its existing literature spanning a number of research traditions, to discuss some of its key issues arising from the work done so far, and to suggest some major research objectives for the future

Getting it Right: Lessons Learned in Applying a Critical Artefact Approach

“Critical artefacts”, the products of critical design (Dunne 1999), prompt reflection rather than satisfy obvious user needs. The author is developing an instrumental use of critical artefacts as part of a human-centred design process. Earlier work showed the effectiveness of this approach in allowing stakeholders to engage with novel product ideas. This paper describes a project, Living Rooms, developing the approach with a broader group of stakeholders and devising the critical artefacts with other designers. Although providing insights into the design context (Bowen & Chamberlain 2008), this application of the approach was less productive than in earlier projects and suggested factors that could affect its efficacy. Implications for future applications of the approach are noted: the type of contexts it is appropriate for; the characteristics of effective stakeholder participants and the need to educate them in the context and enable them to think imaginatively. Von Hippel’s ‘lead users’ (1986, 1988) could provide a framework for selecting stakeholders likely to engage effectively with critical artefacts. The second part of the paper summarises lead user theory and discusses how the two characteristics of lead users, motivation and capability (Luthje & Herstatt 2004), tend to make them suitable participants for the critical artefact approach. A second project, Digital Mementos, is described – in particular how lead-user-based selection and the above implications have been applied. The paper concludes by reviewing the progress in developing generalisable methods exploiting the critical artefact approach, noting the need to position the approach within wider design activity and points toward future work relating it to the entire product design process.

A hybrid evaluation approach and guidance for mHealth education applications

© Springer International Publishing AG 2018. Mobile health education applications (MHEAs) are used to support different users. However, although these applications are increasing in number, there is no effective evaluation framework to measure their usability and thus save effort and time for their many user groups. This paper outlines a useful framework for evaluating MHEAs, together with particular evaluation metrics: an efficient hybrid of selected heuristic evaluation (HE) and usability evaluation (UE) factors to enable the determination of the usefulness and usability of MHEAs. We also propose a guidance tool to help stakeholders choose the most suitable MHEA. The outcome of this framework is envisioned as meeting the requirements of different users, in addition to enhancing the development of MHEAs using software engineering approaches by creating new and more effective evaluation techniques. Finally, we present qualitative and quantitative results for the framework when used with MHEAs
