from Think Aloud to Participatory AnalysisNielsen, Janni (København, 2004)[More information][Less information]
Abstract: Think Aloud is cost effective, promises access to the user’s mind and is the applied usability technique. But "keep talking" is difficult, besides, the multimodal interface is visual not verbal. Eye-tracking seems to get around the verbalisation problem. It captures the visual focus of attention. However, it is expensive, obtrusive and produces huge amount of data. Besides, eye-tracking do not give access to user’s mind. Capturing interface/cursor tracking may be cost effective. It is easy to install, data collection is automatic and unobtrusive and replaying the captured recording to the user and probing about her actions and thoughts open for participatory analysis.

A case study on collaboration with clients, in community interaction and learning designØrngreen, Rikke N.; Nielsen, Janni; Levinsen, Karin (København, 2004)[More information][Less information]
Abstract: Abstract In this paper the Human Computer Interaction (HCI) Research Group reports on the pre-phase of an e-learning project, which was carried out in collaboration with the client. The project involved an initial exploration of the problem spaces, possibilities and challenges for an online accredited Continued Medical Education (CME) programme at the Lundbeck Institute. The CME programme aims at end-users, which are primarily general practitioners, but also specialists (psychiatrist and psychologists), from all over the world. The assumption was that it would be possible to identify and build on resources and competencies already existing in the client organisation. We asked: What is it we know? Uncovering the prerequisites and background of and with the client allowed us concurrently to identify: What do we not know? Working iteratively in collaboration with the client, allowed us to build on existing resources and networks, suggesting a design, which also included end-users community needs and work-context. Our argument is that if a preparation phase both seeks to confirm knowledge and contemplate what is not yet known, giving attention to the context and need of the client (i.e. not only end-users,) then it is possible to build on existing resources within the client organisation, leading to grounding of design decisions and a match between the e-learning environment designed and the capabilities of the client.

A global perspective on ICT and illiteracyNielsen, Janni (København, 2005)[More information][Less information]
Abstract: The process of globalization is opening new windows for Danish initiatives. The requirement for innovation and development of new areas as a consequence of the globalization will lead to radical changes and the IT businesses need to take active part in the development. But in order to understand and explain the globalization process we also have to understand the limitations. One such limitation is found in the global digitalization of information- and communication processes. This global development requires, from the world citizens, literacy in use of computers. The majority of the world populations are illiterates, they are not only technical illiterates but also illiterates in the traditional sense: they cannot read and write, however, the global ICT development largely disregards the problem with illiteracy and cultural differences. It seems that a future area of growth for the Danish IT business with their specific competencies may be to strengthen the user oriented and interdisciplinary approaches to design and development of ICT applications - targeted to specific cultural groups and the illiterates - in developing countries and also to large groups of immigrants in the developed world. India is an example of the global structural changes. India has developed an impressive ICT industry and has a very high level of expertise in software engineering. India’s government has a vision for e-democracy and have implemented e-government systems, which also address the rural populations. But the Indian population is very large and the potential users are highly diverse groups of which many are illiterate. Denmark has an IT industry that supplements India’s, e.g. a strong expertise in e-government, and ICT for the agriculture. Denmark has a long tradition for cooperation between IT developers, researchers and users and is strong in interdisciplinary approaches to development and design of ICT applications. Denmark also has a tradition for a human centred design, and usability is seen as a competitive factor. In India usability is on the agenda in only few IT companies, and it is also new to the academic world (Pradeep Y. 2004). Copenhagen Business School, department of Informatics has for the last 18 months been involved in the establishment of a Euro-India Centre. The departments research group on human-computer interaction(HCI) has prioritized HCI work in the Asian world for the last 4 years (Clemmensen 2004, Nielsen Janni 2004, Nielsen, Clemmensen and Yssing 2002, Levinsen, K. 2002, Nielsen, Lene and Gregers Koch 2003). The wish for a collaborative network has come about as a result of meetings and discussions between researchers from especially India and Denmark and also from Great Britain and Sweden. The first Indian conference on HCI in December 2004 and the initiative from CBS, department of Informatics in May 2005 where an Indian – European workshop was held, created the basis for this network application.

Abstract: Thinking Aloud Thinking Aloud is the most commonly used technique used to test users´ interaction with computers. The assumption is that Think Aloud gives access to what goes on in the users´ minds. However, interfaces are multi modal and play heavily on user´s visual perception. Reflecting upon Think Aloud (TA), we ask the question: what happens when users are required to verbalise their visual perceptions and interactions? We argue that TA may have a disruptive effect, suggesting that other techniques be considered. With a theoretical distinction between focal and subsidiary awareness and a focus on the sense making process, we develop a frame for test of user´s visual interaction which rely on the coordination between hand/mouse and eye/cursor.

Designing for the "cultural other"Nielsen, Janni; Yssing, Carsten; Levinsen, Karin; Clemmensen, Torkil; Ørngreen, Rikke; Nielsen, Lene (København, 2006)[More information][Less information]
Abstract: Differences in cultural contexts constitute differences in cognition, and research has shown that different cultures may use different cognitive tools for perception and reasoning. The cultural embeddings are significant in relation to HCI, because the cultural context is also embedded in the techniques and the tools that we apply. We lack a framework for discussing what and who we are, when we talk about a person as the user of an ICT system that has to be designed, developed and implemented. As a framework, we suggest a theory of complementary positions that insists on solid accounts from all observer posi-tions in relation to perspective, standpoint and focus. We need to develop com-plementary theories that embed complexity, and we need to reflect critically upon forty years of dominance by rationalistic, empirical understandings of the user as illustrated in the literature and practice within the HCI paradigm in system development.

Nielsen, Lene (København, 2004)[More information][Less information]
Abstract: design ideas. The concept of engaging personas and narrative scenario explores personas in the light of what what it is to identify with and have empathy with a character. The concept of narrative scenarios views the narrative as aid for exploration of design ideas. Both concepts incorporate a distinktion between creating, writing and reading.

An HCI Study with the Lundbeck InstituteØrngreen, Rikke N.; Nielsen, Janni; Levinsen, Karin; Stanley Christensen, Elise; Mortensen, Ole E. (København, 2004)[More information][Less information]
Abstract: This working paper presents the first results of a close collaboration between the HCI-Research Group, at the Department of Informatics, CBS and the Lundbeck Institute.This report contains the resulting descriptions of analyses, investigations and evaluations carried out in the pre-phase. The working paper is written considering both the current and future context of the Lundbeck Institute and what we (in the HCI Research Group) know and need to know more about with respect to the future users of the e-learning activities. Another of our concern has been to investigate the Lundbeck Institute current activities and raise questions that the Institute needs to consider when contemplating a relatively large e-learning project. However, we find that the concepts investigated and the processes we have been through have a general relevance. We are thus grateful to the Lundbeck Institute for allowing publication of these pre-phase results. URI: http://hdl.handle.net/10398/6450 Files in this item: 1

On concurrent usability testingNielsen, Janni; Yssing, Carsten (København, 2004)[More information][Less information]
Abstract: ABSTRACT Working with usability techniques, with focus on how a given technique enables data capture made us ask the question: What kind of information is it an HCI expert want from the user when conducting a usability test? We answer the question by discussing two techniques both relying on concurrent data. Think Aloud is one of the most frequently used techniques and almost an institution in itself. Eye-tracking is new in usability testing and still at an experimental level in HCI. We reflect critically upon the two obtrusive techniques. We discuss the usability of concurrent data capture, suggesting participatory analysis and retrospective verbalisation as a possible step in usability testing. Keywords Concurrent data, usability test, Think Aloud, Eye-tracking, mind, participatory analysis and retrospective verbalisation URI: http://hdl.handle.net/10398/6465 Files in this item: 1
