Ubiquitous computing was first articulated by Mark Weiser in his paper “The Computer of the 21st Century” as a world of non-intrusive and omnipresent Information Technology, a world of “embodied virtuality”. Ubiquitous computing envisages a world where IT artefacts are seamlessly integrated into the physical environment, making themselves an integral, invisible part of people’s lives. Ubiquitous computing introduces a set of novel elements, compared to the desktop computing paradigm; ubiquitous computing environments are composed of multiple artefacts instead of personal computers only, they are capable of perceiving contextual information instead of simple user inputs, they are highly embedded in the physical environment, and they support mobility instead of stationary services. The research community has embraced this emerging vision by producing tangible results in such areas as: • Engineering, providing solutions or toolkits in terms of middleware solutions, context
representation and management mechanisms, and sensor fusion. • Interaction design, extending traditional HCI methods and developing new user-interface technologies. • New applications design, implementing innovative systems and services in several application domains, such as office environments, the home, public areas, etc. • Social-related design, investigating environmental and privacy-related issues for ubiquitous computing systems and services. Still, significant research effort is required to fully fulfil the ubiquitous computing vision. On one hand, recent technology developments such as wireless networks, storage and memory capabilities, microelectromechanical systems, and interaction design technologies, are not capable of supporting truly ubiquitous systems. On another hand, new and more effective communication mechanisms need to be devised so the ubiquitous computing research community may always be informed about the latest developments in the field. This workshop serves the aforementioned two purposes by first, consolidating a group of experts in the area and second, providing a forum for discussion on some emerging developments in the ubiquitous computing research ground. A large number of papers were submitted to this workshop, and covered a range of topics ranging from theoretical propositions on system design to core ubiquitous computing infrastructure. A generic taxonomy of the accepted papers is provided in the following paragraphs. Our intention was to select a sufficient number of papers that would cover, as wide as possible, the majority of core research domains in the field of ubiquitous computing. Consequently, the papers cover such issues as: • Middleware-related solutions for ubiquitous computing applications: o Nomadic File Sharing: Proximity Delivery of Mass Content within P2P Social Networks o Discovering Relevant Services in Pervasive Environments Using Semantics and Context • Innovative applications in the field of ubiquitous computing: o Implementing a Pervasive Meetings Room: A Model Driven Approach o M-Traffic - A Traffic Information and Monitoring System for Mobile Devices • Infrastructure Technologies for Ubiquitous Computing in Terms of Location Identification, Service Selection, and Data Management: o Position Estimation on a Grid, Based on Infrared Pattern Reception Features o Visualisation of Fuzzy Classification of Data Elements in Ubiquitous Data Stream Mining • Design prescriptions for effective ubiquitous computing systems development: o Design Guidelines for Analysis and Safeguarding of Privacy Threats in Ubicomp Applications o A Design Theory for Pervasive Information Systems o An Approach for Applications Suitability on Pervasive Environments Last but not least we would like to thank all the authors who submitted papers to this workshop. In addition, we would like to thank the referees for the time and efforts they put into reviewing submissions. Finally, our thanks go to Vitor Pedrosa for his great support.
