I am interested in designing, building, programming, and studying novel post-WIMP (post-“Windows Icons Menus Pointer”) user interfaces and interactive visualizations, e.g., (multi-) touch and gestural user interfaces, tangible user interfaces, or novel apps for interactive tables, walls, or rooms.
I have been working on designs and software frameworks for seamless cross-device interaction and visualization that enable (multiple) users to work across devices and to easily combine them as necessary (e.g. projects HuddleLamp and ZOIL).
I am also working on the human-centered design of the internet of things for smart cities, e.g. how to design urban sensors (see project SenCity) and visualizations to empower citizens (see project Data What?).
On a more theoretical level, I am very interested in how to apply cognitive science and embodied cognition to interaction and visualization design. I have proposed the conceptual framework of Blended Interaction together with my former colleagues of the University of Konstanz as a cognitive model that can help us to design more “natural” technologies with a better user experience. Furthermore, I have worked on a better understanding of fluid interaction for information visualization (e.g. project Facet-Streams).
