Proceedings of the 12th ACM international conference on Ubiquitous computing

Abstract: On behalf of the entire organizing committee, it is our great pleasure to welcome you to the 12th International Conference on Ubiquitous Computing. After North America (2009) and Asia (2008), the UbiComp conference series returns again to Europe, to the vibrant port city of Copenhagen, Denmark. 2010 marks the 12th installment of a conference that truly captures the wide variety of research activities in the diverse field of ubiquitous computing, encompassing research from, e.g., Human Computer Interaction, Mobile Computing, Location and Sensing Technology, Middleware and Systems, and Programming Models and Tools. Each UbiComp conference represents a snapshot of our field, capturing the state-of-the-art in technology, the research challenges we are addressing, as well as the people that form the UbiComp community. Each year's proceedings represent an opportunity to learn about new areas and identify upcoming research opportunities, and this year is no exception. UbiComp 2010 continues the tradition of a single-track technical program that allows participants to experience the entire program in a variety of sessions, ranging from context awareness to location sharing, from home infrastructures to novel interactions, and from persuasive computing to physiological sensing. This year our international Program Committee, composed of 26 of the leading researchers in the field of ubiquitous computing, evaluated 202 submissions - 152 full papers and 50 notes. Using a multi-phase review process, initially each submission was reviewed by at least one member of the program committee and two or more external reviewers. Of the 202 submissions, 131 were evaluated by 1-3 additional PC members. After an online discussion, 9 submissions were auto-accepted and 79 submissions were chosen for further review and discussion at a 2-day PC meeting. In total, the Program Committee and 301 external reviewers spent countless hours to provided feedback to the authors through 848 reviews. After this rigorous process, a total of 39 submissions - 32 full papers and 7 notes - were accepted for publication in these proceedings, representing an overall acceptance rate of 19.3%. We are pleased to note this acceptance rate is the highest in the twelve-year history of the Ubicomp conference thus far. We feel our selective review process has resulted in a high-quality set of published papers. A sub-committee discussed and selected five of the 39 accepted papers to be recognized in these proceedings for their particular level of quality. Of these five, one stood out as the best paper of Ubicomp 2010. This year also sees a significantly expanded adjunct program, accepting 18 demos (1 also as video), 26 posters (3 also as videos), and 10 videos (including the shared ones), making a total of 50 accepted adjunct papers out of 79 submissions. For the first time, we have actively encouraged authors of accepted full papers and notes to also submit a poster, video, or demo of their work, in order to better engage the audience and stimulate face to face discussions. To properly reflect the significance of the work represented in the adjunct program, these submissions also see a much tighter integration in the main program, with video presentations interspersed with the technical presentations of the main track, and posters and demos presented during breaks and the first day's welcome reception. The workshop program has more than doubled the number of workshops, featuring a record-breaking 14 scheduled workshops that cover both traditional UbiComp topics (e.g., context awareness, health, and design) and novel developments (e.g., crowdsourcing, e-energy, and urban computing). Last but not least, Morten Kyng's keynote on "Making dreams come true -- or how to avoid a living nightmare" will offer a critical look at the promises of ubiquitous computing and present design ideas for helping people make sense of this ever increasing technological environment.

Healthy Routes in the Smart City: A Context-Aware Mobile Recommender

Abstract: Smart cities have sensors and communication infrastructures that provide humongous amounts of data. People can extend this infrastructure, acting as independent, mobile sensors through their smartphones, enabling opportunistic sensing. This information provides locality and timeliness of measurements that would otherwise be unavailable. Researchers have developed a context-aware healthy-route recommender system that offers personalized recommendations to people according to their medical condition and real-time information from the smart city. Experiments with a simulated dataset and real data verified the system’s usefulness.

Dynamic Social Structure of Things: A Contextual Approach in CPSS

Abstract: The emergence of cyber-physical-social systems (CPSS) and context-aware technologies has helped boost a growing interest in building frameworks for adaptive smart services that hide heterogeneity in the infrastructure and support services by seamlessly integrating the cyber, physical, and social worlds. However, this entails an enormous amount of computational and networking contextual complexity. Here, the proposed smart services framework in CPSS (called Dynamic Social Structure of Things, or DSSoT) boosts sociality and narrows down the contextual complexity based on situational awareness. DSSoT monitors spatiotemporal situations and, depending on users' individual goals and other social aspects, induces and structures relevant social objects and smart services in a temporal network of interactions. An application using DSSoT, called Airport Dynamic Social, provides a proof of concept.

Modeling and exploiting context for adaptive collaboration

Abstract: Collaborative work is characterized by frequently changing situations and corresponding demands for tool support and interaction behavior provided by the collaboration environment. Current approaches to address these changing demands include manual tailoring by end-users and automatic adaptation of single user tools or for individual users. Few systems use context as a basis for adapting collaborative work environments, mostly focusing on document recommendation and awareness provision. In this paper, we present, firstly, a generic four layer framework for modeling and exploiting context. Secondly, a generic adaptation process translating user activity into state, deriving context for a given focus, and executing adaptation rules on this context. Thirdly, a collaboration domain model for describing collaboration environments and collaborative situations. Fourthly, examples of exploiting our approach to support context-based adaptation in four typical collaboration situations: co-location, co-access, co-recommendation, and co-dependency.

Context-awareness in group work: three case studies

Abstract: There are advantages of using the concept of context in the area of Computer-Supported Cooperative Work. However, it was not the case until now. For example, never the term of awareness has been used in this area with an explicit association to context. We discuss in this paper the interest to make context explicit in three case studies in the domain of collaborative works. In particular, we propose a framework to understand how context and awareness are related together and to other concepts used in group works, such as user interface and storage. The proposed framework is used to consider groupware systems presented in this paper from the context perspective and to eventually obtain some insight on possible improvements for users.
