Last week, I gave a little presentation at the colloquium of the media informatics faculty at TU Dresden. Find the slides here. I would also like to use the chance to make you aware of the OUTPUT event on April 23, where student and research works are presented and some interesting talks are planned. For readers of this blog, probably the Technische Visualistik track will be most interesting, with talks about multi-touch, blended interaction, touchless interaction etc.
