For the CeBIT 2000, the Fraunhofer IGD Rostock developed the official electronic exhibition guide (eGuide) for palmsized computers and is thereby founding a new generation of personal assistant for fairs and exhibitions. This report describes the concepts and experiences with the application which has already been used by more than 40.000 user. Introduction(More)
Mobile and ubiquitous systems require task models for addressing the challenges of adaptivity and situation-aware assistance. Today , both challenges are seen as separate issues in system development, addressed by different modeling concepts. We propose an approach for a unified modeling concept that uses annotated hierarchical task trees for synthesizing(More)
Among the scenarios for pervasive learning are teleteaching and project work. The former tries to deliver a lecture to a distributed audience, while the latter tries to enhance the learning effect by concentrated collaboration. In this paper, we want to show how an ambient environment, designed to support teams in a meeting, can be used to support pervasive(More)
Emerging multiple display infrastructures provide users with a large number of semi-public and private displays. Selecting what information to present on which display here becomes a real issue, especially when multiple users with diverging interests have to be considered. This especially holds for dynamic ensembles of displays. We propose to cast the(More)
Ubiquitous computing aims for the realisation of environments that assist users autonomously and proactively in a non-distractive manner. Therefore smart environment infrastructures need to be able to identify users needs (intention recognition) and to plan an appropriate assisting strategy (strategy generation) without explicit user interaction. In our(More)
Ubiquitous computing aims for the realization of environments that assist users autonomously and proactively. Therefore smart environment infrastructures need to be able to identify users needs (intention recognition) and to plan an appropriate assisting strategy. Both is matter for research. In our approach we address inferring the intention of a team(More)
