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 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)

Innerhalb der Bildungsinstitution Museum entstehen durch den Einsatz von Informations-und 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)
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)
