New technologies and new ways of interacting with these technologies are of huge interest; they enable new business models and ways of making sense of this most important aspect of our everyday lives. At the same time, money is an essential element in HCI research and design. This workshop is intended to bring together researchers and practitioners involved in the design and use of systems that combine digital and new media with monetary and financial interactions to build on an understanding of these technologies and their impacts on users' behaviors. The workshop will focus on social, technical, and economic aspects around everyday user interactions with money and emerging financial technologies and systems.

We take the analytic perspective of distributed cognition to examine the role that these artifacts have on information processing activity in augmenting human action and in transforming the problem space. The analysis is further used in identifying issues for cognitive engineering in the design of spatial, augmentative resources to support collaborative problem solving.

At the same time, the increasing penetration and take-up of robust high-speed networks, dependable peer-to-peer architectures and mobile multimedia technologies enable novel platforms for offering financial services to current and new users. These new forms of digital connectivity give rise to opportunities in doing financial transactions in different ways and with radically different business models that offer the possibility of transforming the marketplace. One key area of transformation in the digital economy involves retail-level digital banking and payment services. The impact of the new economic models presented by these digital financial services is yet to be fully determined, but they have huge potential as disruptive innovations, with a potentially transformative effect on the way that services are offered to users. Little is understood about how technical infrastructures impact on the ways that people make sense of the financial services that they use, or on how these might be designed more effectively. 3DaRoC is exploring this space by working with our partners and end users to co-design and evaluate new opportunities for online, mobile, ubiquitous and tangible technologies, exploring how these services might be extended, and offering insights for regulators, innovators, designers, and end-users of disruptive financial technologies.

The approach gives the fieldworker a theoretical basis for structuring the analysis of data from their workplace studies within a problemsolving framework. Whilst the approach has been successfully applied in well constrained activity domains that involve closed systems, well structured problems and highly organised infrastructures, little is known about it application outside of these areas. In this paper, we explore how distributed cognition can be migrated to less highly constrained settings, and where difficulties lie in its application. To demonstrate this, we present and critically reflect on data from a field study with relatively poorly constrained features. The findings suggest that the use of distributed cognition in an augmented form will be useful in the analysis of a wide range of collaborative systems in poorly constrained and complex organisational settings.

While digital technologies offer promises in supporting these difficulties, researchers appear reluctant to discontinue their use of analogue resources. We present a study of communication practices in very large-scale collaborative scientific research programmes that involve multidisciplinary and multinational research consortia. Qualitative data collection with researchers, principal investigators and project coordinators were carried out to examine the conduct and coordination of biological, biomedical and chemistry experiments that were distributed over multiple geographical locations. Results show that many problems in collaboration appear to result from the collective documentation of experimental operating procedures, tracking of experimental samples, and the sharing and cross-association of physical and digital experimental materials. Our analysis highlights the crucial but problematic role of the laboratory notebook as a driver for collaboration, most notably in supporting traceability of the distributed experimental process. We identify opportunities for improving experimental coordination, scientific communication and project synchronisation, drawing implications for digital interaction design that offers opportunities to enhance research coordination.

These workshops follow on from our investigations into the social and technological infrastructures of the Bristol Pound (£B) and Zopa Limited. Our findings, described in other reports, have been fed back into the development of probes used in the design workshops and have allowed us to continue to explore the financial service design space in ways that exclusively studying existing practice could not.

They found that local mobility was critically important in supporting communication and awareness activities in the work practises under investigation. Bellotti and Bly observed that collocating with a colleague allowed a richer level of access to co-workers than was possible using telecommunication tools from the desktop. Local mobility, also facilitated access to colleagues that provided workers with an awareness of what was going on elsewhere in the workplace - with notably numerous 'ad hoc' informal meetings taking place throughout the day. However, the cost of such local mobility came in the form of limiting the telephone access to co-workers for remote colleagues - since the co-workers they wished to talk to were often not at their desks when they phoned

Still little is known about how mobile technologies are used amongst different populations in specific contexts and this research addresses the context of work use by blue-collar workers with an aim to augmenting this with new mobile technologies better suited to their informational and communicative needs.Most of the current public domain research into mobile device use practice concentrates primarily on professional workers (the ubiquitous 'mobile professional') and 'knowledge workers' (e.g. Bellotti and Bly, 1996; O'Hara et al. 2001). It seeks to discover how mobile technology, particularly Personal Digital Assistants (PDA's) and 'communicators', can be designed to help mobile professionals retain a sense of awareness of their workplace and work ...

While families travelling in cars may face stress from difficult road conditions, they are also likely to be frustrated by coordinating a number of activities and resolving disputes within the confined space of car. A rising number of in-car infotainment and driver-assistance systems aim to help reduce the stress from outside the vehicle and improve the experience of driving but may fail to address sources of stress from within the car. From ethnographic studies of family car journeys, the authors examine the work of parents in managing multiple stresses while driving, along with the challenges of distractions from media use and disputes in the car. Keeping these family extracts as a focus for analysis, we draw out some design considerations that help build on the observations from our empirical work.

Until recently, a common distinguishing feature of these text-based advertisements has been their background color. Following intervention by the Federal Trade Commission (FTC), the format of these advertisements has undergone a subtle change in their design and presentation. Using three empirical experiments, we investigate the effect of industry-standard advertising practices on click rates, and demonstrate changes in user behavior when this familiar differentiator is modified. Using three large-scale experiments (N 1 = 101, N 2 = 84, N 3 = 176) we find that displaying advertisement and content results with a differentiated background results in significantly lower click rates. Our results demonstrate the strong link between background color differentiation and advertising, and reveal how alternative differentiation techniques influence user behavior.

In contrast to many of the other papers in this collection, the objective of this chapter is to examine individual mobile work, and not teamwork and cooperation other than where it impacts on the work of individuals. We present data from a study of mobile workers, examining a range of mobile workers to produce a rich picture of their work. Our analysis reveals insights into how mobile workers mix their mobility with their work, home and social lives, their use of mobile technology, the problems-technological and otherwise-inherent in being mobile, and the strategies that they use to manage their work, time, other resources and availability. Our findings demonstrate important issues in understanding mobile work, including the maintenance of communities of practice, the role and management of interpersonal awareness and coordination, how environmental resources affect activity, the impact of mobility on family/social relationships and the crossover between the mobile workers' private and working lives, how preplanning is employed prior to travel, and how mobile workers perform activity multitasking, for example through making use of 'dead time'. Finally, we turn to the implications of this data for the design and deployment of mobile virtual work (MVW) technologies for individuals and a broader organisational context.
