Pervasive 2009 had a really exciting program and provided a good overview of current research in pervasive and ubiquitous computing. Have a look at the proceedings of the pervasive 2009 conference. The Noh theater in Nara was a very special and enjoyable venue and it was organized perfectly – as one would expect when travelling to Japan.

The idea of having short and long papers together in the main track worked very well in my view. The number of demos and posters was much higher than in the years before – and that was great and very inspiring. Have… Continue reading

Toshio Iwai gave the keynote at Pervasive 2009 on expanding media art. He introduced us to the basics of moving images and films. The examples were fun and I think I will copy some for my introductory class on user interfaces for explaining the visual system (afterimages with a black-and-white negative image; the concept of combining images on two sides of a disk; the idea of moving images by using a flip book).

To get cheaper flights we took a flight on Thursday/Friday to fly from Europe to Japan (never really understood the pricing model of flights). So we had two days off before the actual conference and many colleagues (who also took cheap flights) were also there. We went to do some sightseeing in Nara and Kyoto – which was great.

In Kyoto we got personal guides – students from a University in Kyoto – who offered to show us run and use this to practice their English. It was great for us as we got many insights we would have missed… Continue reading
