The rapid and accelerating move towards the adoption and use of mobile technologies has increasingly provided people and organisations with the ability to work away from the office and on the move. The new ways of working afforded by these technologies are often characterised in terms of the access to information and people 'anytime, anywhere'. This paper problemarises the rhetoric of 'access anytime, and anywhere' and presents a study of mobile workers that highlights different facets of access to remote people and information, and different facets of anytime, anywhere. Four key factors in mobile work are identified from the study: the role of planning, working in 'dead time', accessing remote technological and informational resources, and monitoring the activities of remote colleagues. By reflecting on these issues, we can better understand the role of technology and artefact use in mobile work and identify the opportunities for the development of appropriate technological solutions to support mobile workers.

There have been many attempts to support awareness and lightweight interactions using video and audio, but few have been built on widely available infrastructure. Text-based systems have become more popular, but few support awareness, opportunistic conversations, and mobility, three important elements of helping distributed groups coordinate. We built on the popularity of text-based Instant Messengers (IM) by building a mobile IM called Hubbub that tries to provide all three, notably through the use of musical sounds. In a 5.5-month use study, we found that Hubbub helped people feel connected to others in different locations and supported opportunistic interactions. Sound was a useful cue for helping people feel connected, although some found it annoying. It was more important to support graceful transitions between multiple fixed locations than to support wireless access, although both were useful.

This paper addresses issues of user interface design, relating to ease of use, of handheld CSCW. In particular, we are concerned with the requirements that arise from situations in which a traditionally designed mobile computer with a small keyboard and screen, may not be easily used. This applies to many mobile use contexts, such as inspection work and engineering in the field. By examining two such settings, we assert that what is usually pointed to as severe shortcomings of mobile computing today, for example: awkward keyboard, small display and unreliable networks, are really implications from a conceptual HCI design that emphasise unstructured, unlimited input; a rich, continuous visual feedback channel and marginal use of sound. We introduce MOTILE, a small prototype that demonstrates some alternative ideas about HCI for mobile devices. We suggest that identifying complementing user interface paradigms for handheld CSCW may enhance our understanding not only of mobile computing o...

Anomadic information environment is a heterogeneous assemblage of interconnected technological, and social, and organizational elements that enable the physical and social mobility of computing and communication services between organizational actors both within and across organizational borders. We analyze such environments based on their prevalent features of mobility, digital convergence, and mass scale, along with their mutual interdependencies. By using a framework that organizes research topics in nomadic information environments at the individual, team, organizational, and interorganizational levels and is comprised of both service and infrastructure development, we assess the opportunities and challenges for IS research. These deal with the design, use, adoption, and impacts of nomadic information environments. We conclude by discussing research challenges posed by nomadic information environments for information systems research skills and methods. These deal with the need to invent novel research methods and shift our research focus, the necessity to question the divide between the technical and the social, and the need to better integrate developmental and behavioral (empirical) research modes.

Mobile urban environments present a challenge for context-aware computers because they differ from fixed indoor contexts such as offices, meeting rooms, and lecture halls in many important ways. Internal factors such as tasks and goals are different---external factors such as social resources are dynamic and unpredictable. An empirical, user-centred approach is needed to understand mobile contexts. In this paper, we present insights from an ethnomethodologically inspired study of 25 adult urbanites in Helsinki. The results describe typical phenomena in mobility: how situational and planned acts intermesh in navigation, how people construct personal and group spaces, and how temporal tensions develop and dissolve. Furthermore, we provide examples of social solutions to navigation problems, examine mobile multitasking, and consider design implications for mobile and context-aware human-- computer interaction.

The emergence and convergence of Information and Communication Technologies (ICTs) are fundamentally transforming the use of technology, and in particular concerning the issues of mobility. The current debates on mobility, however, almost exclusively consist of functionalist analyses of how particular mobile technologies can alleviate geographical barriers for human activity. This paper reconsiders, from a theoretical perspective, the concept of mobility. We argue that mobility should not exclusively be linked to human corporeal travel. The concept also relates more broadly to the interaction people perform. In order to appreciate the relationship between mobility and human interaction, three interrelated dimensions are discussed — spatial, temporal, and contextual aspects of mobility. In order to characterize the social topology of ICT supported mobilized interaction, we suggest and discuss the adoption of a fluid metaphor. Based on these discussions, a case of a new mobile technology system introduced in a Japanese distribution service firm is discussed. 1.

This paper reports fieldwork from the electrical utilities industry, examining the suitability of current knowledge management perspectives to the day-to-day work of mobile staff. Reporting the results of the empirical study, we make a distinction between four aspects of local and mobile "knowledge management" as it took place in the mobile work setting: sharing, i.e., several parties exchange knowledge; indexing, i.e., one party explains to another what knowledge to retrieve; diagnosing, i.e., two parties make sense of how to interpret a situation, and; foreseeing, i.e., one party (or more) uses knowledge to project the future. We compare and contrast the empirical findings with current knowledge management perspectives, and outline an initial sketch of a framework for "practical knowledge management."

This paper reports findings from a study of how a guidebook was used by pairs of visitors touring a historic house. We describe how the guidebook was incorporated into their visit in four ways: shared listening, independent use, following one another, and checking in on each other. We discuss how individual and groupware features were adopted in support of different visiting experiences, and illustrate how that adoption was influenced by social relationships, the nature of the current visit, and any museum visiting strategies that the couples had. Finally, we describe how the guidebook facilitated awareness between couples, and how awareness of non-guidebook users (strangers) influenced use.

Many IT companies recognise the importance of wireless communication in the development of new technologies. In order to better inform this development, this paper describes a study of mobile professionals focussing on their communication and document activities. The findings indicate the particular importance of verbal communication for these people and hence the value of the mobile phone. The study also brings to the fore the relationship between their use of the phone and their document activities. The findings have allowed us to develop a taxonomy of this relationship that provides a useful resource for thinking about design implications and new technology supporting mobile work.

Abstract: We are investigating how people move from individual to group work through the use of both personal digital assistants (PDAs) and a shared public display. Our scenario of this work covers the following activities. First, mobile individuals can create "personal " notes on their PDAs. Second, when individuals meet in real time, they can selectively "publicise " notes by moving them to a shared public display. Third, the group can manipulate personal and public items in real time through both PDAs and the shared public display, where the notes contained on both PDAs and public display are automatically synchronised. Finally, people leave a meeting with a common record of their activity. We describe our SharedNotes system that illustrates how people move through this scenario. We also highlight a variety of problematic design issues that result from having different devices and from having the system enforce a rigid distinction between personal and public information.
