Li, Jane, Robertson, Toni, Hansen, Susan, Mansfield, Tim and Kjeldskov, Jesper (2008): Multidisciplinary medical team meetings: a field study of collaboration in health care. In: Proceedings of OZCHI08 - the CHISIG Annual Conference on Human-Computer Interaction 2008. pp. 73-80. Available online
“We present an observational study that was conducted to guide the design of an enhanced collaboration platform to support distributed multidisciplinary team meetings between two hospitals. Our goal was to find out how the breast cancer multidisciplinary team collaborates in their face-to-face meetings and in their discussions using an existing video-conferencing system and to identify obstacles and issues to their primary tasks. We identified a set of concerns around the way visibility and audibility affect the social cohesion of the group and impede communication and situation awareness between the distributed team. We also identified a parallel set of concerns around the difficulty of preparing and interacting around the medical images used in the meetings. These issues exposed a complex matrix of technical, social, procedural and organisational factors that affect the collaboration. We suggest potential directions for technical interventions in this setting.”

“Reality is everywhere. It is right there in our face when we wake up and it continues to sneak up on us throughout our day, in the car, in our offices, and at the dinner table. In recent years it has even invaded our TVs through eternal news streams and endlessly boring reality TV shows. However, people cannot live by reality alone. In fact, we spend quite a lot off effort on escaping reality. We daydream and immerse ourselves in imaginary worlds and stories. We immerse ourselves in fiction. Inspired by this view, we report on our research into the design and user experience of a new genre of mobile location-based services, which uses peoples' physical surroundings as a backdrop for storytelling as they move around an urban environment. We present a prototype system developed to explore the user experience of location-based interactive stories, and the use of interaction designs aimed at blurring the boundary between reality and fiction. Based on qualitative data from a series of field trials, we discuss potentials and challenges for this class of location-based services.”

Kjeldskov, Jesper and Skov, Mikael B. (2007): Studying Usability In Sitro: Simulating Real World Phenomena in Controlled Environments. In International Journal of Human-Computer Interaction, 22 (1) pp. 7-36
“Increased complexity of organizations and emerging technologies poses new and difficult challenges for the evaluation of software systems. Several years of research have proven that usability evaluations are invaluable tools for ensuring the quality of software technologies, but the increased complexity of technology requires new ways of understanding and evaluating the quality of software systems. This article explores limitations, challenges, and opportunities for studying mobile technologies "in use, in situ;" in laboratories (in vitro); and in controlled high-fidelity simulations of the real world. The latter condition is called "in sitro". This report comes from 2 different case studies of evaluating the usability of mobile systems within these 3 different conditions. Results show that it is possible to recreate and simulate significant elements of intended future use situations in laboratory settings and thereby increase the level of realism and maintain a high level of control. In fact, the in sitro condition was able to identify most of the same usability problems as found in the other conditions. However, the in situ evaluation proved to provide a level of realism that is difficult to achieve in laboratory environments.”

In: Proceedings of OZCHI07, the CHISIG Annual Conference on Human-Computer Interaction November 28-30, 2007, Adelaide, Australia. pp. 25-28. Available online
“This paper elaborates on previous research into the design and use of mobile information systems for supporting the use of public transportation. Contributing to this domain of HCI research, we describe the design and evaluation of a mobile travel planner, Buster, for the public city bus system of a large regional city in Denmark. Carrying on from on earlier research activities, we did contextual interviews, acting out of future scenarios in situ, and iterative paper prototyping to extend on previous design ideas and explore further the principle of indexicality in interface design for context-aware mobile systems. We then implemented a functional prototype application and evaluated it in the field.”

In: Proceedings of OZCHI07, the CHISIG Annual Conference on Human-Computer Interaction November 28-30, 2007, Adelaide, Australia. pp. 273-281. Available online
“In this paper, we describe GeoHealth -- a geographical information system prototype for home healthcare workers who during a normal workday have to attend clients and patients that are physically distributed over a large geographical area. Informed by field studies of work activities and interviews with the healthcare workers, we have designed an interactive location-based service for supporting distributed mobile collaboration. The prototype explores a representational approach to context-awareness and represents live contextual information about clients/patients, co-workers, current and scheduled work activities, and alarms adapted to the users' location. The prototype application is web-based and uses Google Maps, GPS positioning, and Web 2.0 technology to provide a lightweight dynamic and interactive representation of the work domain supporting distributed collaboration, communication, and peripheral awareness among nomadic workers.”

Paay, Jeni and Kjeldskov, Jesper (2007): A Gestalt theoretic perspective on the user experience of location-based services. In: Proceedings of OZCHI07, the CHISIG Annual Conference on Human-Computer Interaction November 28-30, 2007, Adelaide, Australia. pp. 283-290. Available online
“Location-based services provide mobile users with information and functionality tailored to their geographical location. Within recent years these kinds of context-aware mobile systems have received increasing attention from software industry as well as from researchers within a wide range of computing disciplines. However, while a lot of research has been done into sensing, adapting and philosophizing over the complex concept of "context", little theoretically based knowledge exists about why, from a user experience perspective, some context-aware system designs work well and why others don't. Contributing to this discussion, this paper suggests the perspective of "Gestalt theory" as a potential theoretical framework for understanding the use of this class of computer systems, and argues that describing the user experience of location-based services through Gestalt theory's principles of proximity, closure, symmetry, continuity, and similarity can help explain how people make sense of small and fragmented pieces of information on mobile devices in context.”

“On the basis of a longitudinal field study of domestic communication, we report some essential constituents of the user experience of awareness of others who are distant in space or time, i.e. presence-in-absence. We discuss presence-in-absence in terms of its social (Contact) and informational (Content) facets, and the circumstances of the experience (Context). The field evaluation of a prototype, 'The Cube', designed to support presence-in-absence, threw up issues in the interrelationships between contact, content and context; issues that the designers of similar social artifacts will need to address.”

Kjeldskov, Jesper and Stage, Jan (2006): Exploring 'Canned Communication' for coordinating distributed mobile work activities. In Interacting with Computers, 18 (6) pp. 1310-1335
“Communication between physically distributed people in industrial and safety-critical domains is often spoken and mediated through walkie-talkies, or closed-circuit intercoms. Because this kind of communication is hampered by noise, radio interference, lack of persistency, etc. vital information is sometimes lost. In response to this challenge, this paper discusses the use of 'canned' text-based messaging as a supplement for improving such communication. Based on data from ethnographic studies of work activities in an industrial domain, and grounded in a theoretical model of communication, we have designed and evaluated a mobile canned communication prototype system facilitating exchange of predefined text messages, a persistent graphical representation of the operation in progress, and a filtered list of completed tasks. Results from two evaluations show that in the domain considered, canned text-based communication has a potential to supplement voice and assist in overcoming some of the inherent problems of spoken communication. Yet using a textual and persistent mode of communication also raises new challenges such as choice of modality, speed, flexibility and handling situations deviating from standard procedures.”

“This paper presents findings from a current research project focusing on challenges of interaction design for context-aware mobile computer systems. These challenge are approached from a novel perspective on context awareness; by exploiting knowledge about the user's context to create indexical user interfaces that carry a major part of their meaning implicitly through the settings in which they are used, thus reducing the need for explicit information representation cluttering the limited screen real estate of mobile devices. The project aims at creating a theoretical foundation for future research into interaction design with context-aware mobile computer systems and to develop the concept of indexicality as an interaction design principle for such systems. Achieving this, we are conducting a theoretical as well as a technical stream of research involving field studies into the context of mobile computer system use and experimental design, implementation and evaluation of prototype systems.”

In: Kjeldskov, Jesper and Paay, Jane (eds.) Proceedings of OZCHI06, the CHISIG Annual Conference on Human-Computer Interaction 2006. pp. 95-102. Available online
“Communication and coordination of mobile and distributed work activities is a challenging application domain for mobile handheld devices. In this paper, we present the design of a mobile system to support communication and coordination between workers in safety-critical tasks in a power plant. The design of the system was based on ideas inherited from a communicator that was developed for a different application domain. The design was devised through a combination of ethnography and object-orientation. The mobile system we designed provides location-aware access to computerized information and process control on a handheld wireless computer terminal.”

In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 471-480. Available online
“Intimacy is a crucial element of domestic life, and many interactive technologies designed for other purposes have been appropriated for use within intimate relationships. However, there is a deficit in current understandings of how technologies are used within intimate relationships, and how to design technologies to support intimate acts. In this paper we report on work that has addressed these deficits. We used cultural probes and contextual interviews and other ethnographically informed techniques to investigate how interactive technologies are used within intimate relationships. From this empirical work we generated a thematic understanding of intimacy and the use of interactional technologies to support intimate acts. We used this understanding to inform the design of intimate technologies. A selection of our design concepts is also presented.”

“People in close relationships, who are separated by distance, often have difficulty expressing intimacy adequately. Based on the results of an ethnographic study with couples, a prototype was developed to test the feasibility of technology in the domain of intimacy. Hug Over a Distance is an air-inflatable vest that can be remotely triggered to create a sensation resembling a hug. Although the couples did not consider the vest to be useful in their daily lives, the prototype served to provoke and stimulate design ideas from the couples during participative design workshops. An additional and unexpected benefit was also found: the prototype enhanced the couples' understanding of the researchers' methods, suggesting that prototypes can serve as tools to make participatory design volunteers aware of their importance in academic research.”

“Designing context-aware mobile information systems for supporting sociality requires a solid understanding of the users' context, situated interactions, and the interplay between the two. Currently such understanding is lacking in the field of HCI research and is sought after by several authors. Addressing this gap we conducted a field study of small groups socialising in a public place. Based on a grounded analysis of our findings we present a conceptual framework of situated social interactions in public. Finally, we illustrate how this framework informed design of a mobile context-aware prototype.”

“Mobile computer technologies are increasingly being appropriated and used to facilitate people's social life outside the work domain. Addressing this emerging domain of use, we present the design of a context-aware mobile information system prototype facilitating sociality in public places: Just-for-Us. The design of the prototype system was informed by two empirical studies: an architectural analysis of a recently built public space in Melbourne, Australia and a field study of small groups socialising there. We describe these two studies and illustrate how findings informed our prototype design. Finally, we outline an ongoing field study of the use of the Just-for-Us prototype.”

“The last decade has seen convergence marketed as one response to the challenge of users having to juggle an increasingly wide array of digital services, technologies and media. Key to this view is the assumption that by converging computer devices, and digital media, the value of technology for end users can be maximised whilst the overheads involved in purchasing, maintaining and orchestrating a variety of different technology solutions can be minimised. In contrast however, some authors have argued that convergence creates weak-general solutions, and rather we should be aiming for strong-specific technology by means of the deliberate design of multiple diverged devices. This paper contributes to the ongoing discussion of convergence and divergence. We discuss three apparently irreconcilable perspectives on the relationship between functionality and usability, and show that they are in fact complementary views of convergence. To ground this discussion we draw on the results of a recent cultural probes study of a cohort of early adopters of converged devices.”

“We report from a longitudinal laboratory-based usability evaluation of an interactive system. A usability evaluation was conducted with novice users when a large commercial electronic patient record system was being deployed in the use organization. After the users had used the system in their daily work for 15 months, same evaluation was conducted again. Our aim was to inquire into the nature of usability problems experienced by novice and expert users over time, and to see to what extends usability problems may or may not disappear over time, as users get more familiar with the system. On the basis of our two usability evaluations, we present key findings on the usability of the evaluated system as experienced by the two categories of users at these two different points in time. Based on our findings, we discuss implications for evaluating usability.”

“We present the design of "Just-for-Us" -- a context-aware web site for mobile devices augmenting the social experience of the city. Informing design, field studies of social groups' situated social interactions were carried out in a new civic space in Melbourne, Australia followed by paper prototyping and implementation of a functional mobile web site. The produced solution augments the city through web-based access to a digital layer of information about people, places and activities adapted to users' physical and social context and their history of social interactions in the city. The system was evaluated in lab and field, validating the fundamental idea but also identifying a number of shortcomings.”

Kjeldskov, Jesper and Stage, Jan (2004): New techniques for usability evaluation of mobile systems. In International Journal of Human-Computer Studies, 60 (5) pp. 599-620
“Usability evaluation of systems for mobile computers and devices is an
emerging area of research. This paper presents and evaluates six techniques for
evaluating the usability of mobile computer systems in laboratory settings. The
purpose of these techniques is to facilitate systematic data collection in a
controlled environment and support the identification of usability problems
that are experienced in mobile use. The proposed techniques involve various
aspects of physical motion combined with either needs for navigation in
physical space or division of attention. The six techniques are evaluated
through two usability experiments where walking in a pedestrian street was used
as a reference. Each of the proposed techniques had some similarities to
testing in the pedestrian street, but none of them turned out to be completely
comparable to that form of field-evaluation. Seating the test subjects at a
table supported identification of significantly more usability problems than
any of the other proposed techniques. However a large number of the additional
problems identified using this technique were categorized as cosmetic. When
increasing the amount of physical activity, the test subjects also experienced
a significantly increased subjective workload.”

“When designing a usability evaluation, 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 the critical usability problems in the system being evaluated. At the same time, the noise of unique usability problems usually characterizing video data analysis was significantly reduced.”

“We present the process of designing the first prototype of the Handheld Maritime Communicator: a mobile computer system supporting communication and coordination of safety-critical work activities on large container vessels. Designing the user experience of the Handheld Maritime Communicator was a particular challenge because it targets a highly specialized context of use and because poor design could potentially become a safety hazard. Meeting this challenge, ethnographic field studies on board container vessels were conducted, detailed analyses were carried out, and iterative design was performed. The design produced replaces a large amount of present spoken communication with predefined textual messages on a handheld device. This facilitates persistency, partial automation, and possible integration with other computer-based data. Evaluating the prototype in a high-fidelity ship simulator, prospective users validated the overall design, but also identified a number of usability problems that need to be addressed.”

“We describe the design of a mobile information service that provides users with a route-planning tool for the tram-based public transport system of Melbourne, Australia. The design sketches for TramMate represent early iterations of an ongoing design process based on data from field studies on the use of transportation by business employees who, during a typical workday, have to attend appointments at different physical locations. TramMate supports this activity by keeping track of contextual factors such as the user's physical location, upcoming appointments, and real-time travel information. The design is integrated with an electronic calendar and alerts the user when it is necessary to commence the journey.”
