In this paper, we address the problem of designing for participation and parallel interaction with a walk-up-and-use tabletop system in a public exhibition environment. Motivated by the work practice of territoriality, we implement a novel, tabletop-integrated multi-user tracking system that provides data on a user's location and movement. Based on this(More)
In this note we introduce Body Panning, a novel interaction technique for horizontal panning on interactive surfaces. Based on an established sensory hardware setup, we implemented a robust body tracking system for a large-scaled tabletop. On this basis a user can pan through a spatial user interface by adjusting her position at the table. As a natural form(More)
In this paper we argue for a combined approach of logging analysis and interview techniques to evaluate the usability of web distributed applications. Logging analysis has proven as an efficient and effective method to investigate websites usability. However it seems insufficient for more complex applications. We outline a case study of a library search(More)
This paper analyzes public data sources and their requirements for the transition from school to vocational training and career of people with disabilities in the context of Article 31 of the UN-Convention on Rights of People with Disabilities. Different focuses of the public data sources within the involved systems and challenges in data analysis will be(More)
Innerhalb der Bildungsinstitution Museum entstehen durch den Einsatz von Informationsund Kommunikationstechnologien (IuK) neue Möglichkeiten der Informationsvermittlung. Im Blended Museum wird versucht, virtuelle und reale Präsentationsformen miteinander zu vermischen. Dies ermöglicht hybride Vermittlungsstrategien, die neue und vor allem vielfältigere(More)

Vor nicht einmal 20 Jahren wurde mit dem DigitalDesk der erste interaktive Schreibtisch vorgestellt (Wellner, 1993). Dieser ermöglichte es dem Benutzer, physische und digitale Dokumente auf verschiedene Arten zu manipulieren und zu kombinieren. Vergleicht man die grundlegenden Systemkomponenten von damals ein Schreibtisch, eine Kamera, ein Projektor und ein(More)
In this paper we report our findings from an exploratory design study using a combination of an interactive tabletop and digital pen & paper technology during a full-day creativity workshop with creative professionals. We describe the applied creativity technique, the system design and the employed interaction techniques. The preliminary results of our(More)
