Preface: Workshops Proceedings of the 5th International Conference on Intelligent Environments: Barcelona, Spain, 19th of July, 2009

We are witnessing an historic technological revolution as computing reaches maturity to become immersed in our daily life to an extent that some decades ago was considered science fiction. Advances in the engineering of sensing and acting capabilities distributed in wide range of specialized devices is providing at last an opportunity for the fundamental advances that computer science achieved in the past few decades to make an impact in our daily lives. This technical confluence is matched by a unique historical context where users are better informed (and more aware of the benefits that technology can provide) and production of more complex systems is becoming more affordable. Sensors/actuators deployed in an environment (in this context it can be any physical space like a house, an office, a classroom, a car, a street, etc.) facilitate a link between an automated decision making system connected to that technologically enriched space. This computing empowered environment enables the provision of an intelligent environment, i.e., "a digital environment that proactively, but sensibly, supports people in their daily lives". This is a very active area of research which is attracting an increasing number of professionals (both in academy and industry) worldwide. The prestigious 5th International Conference on Intelligent Environments (IE'09) is focused in the development of advanced Intelligent Environments and stimulates the discussion on several specific topics which are crucial to the future of the area. As part of that effort to stimulate developing in critically important areas five workshops were supported as part of IE'09. This volume is the combined proceedings of those five workshops.
