The 8th International Conference on Ubiquitous Computing focused on new middleware, software engineering approaches, widescale interdomain deployment, techniques and benchmarking for evaluation of ubicomp systems. The conference featured two paper sessions and three panel discussions to discuss the possibility of common set of ubicomp abstractions and a platforms to facilitate research. Researchers presented their research covering new applications and services for capturing images and context, augmenting the images and context with sound, and sharing them via the Web or in printed form. Various participants stressed the need of evaluation and benchmarking of ubicomp systems research. The use of furniture and architecture with integrated electronics, and room-based sensor system, was presented. Various features of integrated document and metadata system used for supporting different types of sessions, security, privacy, and efficient document handling, were discussed.
