In co-located meetings, which are part of our professional and educational lives, information exchange relies not only on information exchange using artifacts like bubbles in mind-maps or equations presented on electronic whiteboards in classrooms, but also to a large extent on non-verbal communication. In the past much effort was done to make the artifact level accessible but also non-verbal c...

We examine the properties and use of paper in everyday settings and discuss the motivation for retaining paper as an information medium. In particular, we consider the use of paper maps and guidebooks by tourists during city visits as an example of a mobile and collaborative environment. We then go on to present recent developments in technologies for digital paper and how they can be used to s...

This paper introduces basic concepts of rule based test generation with mind maps, and reports experiences learned from industrial application of this technique in the domain of smart card testing by Giesecke &Devrient GmbH over the last years. It describes the formalization of test selection criteria used by our test generator, our test generation architecture and test generation framework.

This paper proposes a concept to use a 2D tactile mind map tool for a better integration of blind people into co-located meetings with the goal of structuring and organizing ideas during ideation. We mainly focus on presentation techniques to present mind maps to blind users. We discuss problems of existing analogue and digital tools, which support structuring and organizing ideas, for blind me...
