Visit to the Arithmeum in Bonn

For people who already arrive on Sunday, the day before the conference, we organised some museum visits: Arithmeum, Haus der Geschichte, Deutsches Museum, and Art Gallery. I only had time to see the Arithmeum (http://www.arithmeum.uni-bonn.de/) which was pretty impressive. Hiroshi Ishii (the keynote speaker of the conference) and Brygg Ullmer (last years conference co-chair) joined us, too.

It was unexpected how close the displayed artefacts are to our current research on tangible interaction. We had a very good guided tour by Nina Mertens, who gave us an interesting overview from counting tokens to calculation machines. Some of the exhibit we could even try out our selves.

I found the aspect of aesthetics in some of the calculation aids and machines quite fascinating. Especially the fact that some were so precious that they were not really used for calculating but more for showing off is a concept that is amazing. Similarly interesting was one artefact that was mainly built as a proof that calculation can be automated.
