Raimund Dachselt presented FaceZoom, a widget for quick navigation, e.g. for a tree structure [1]. I liked his characterizing “a stacked treemap” – which explains nicely what the widget does and where the efficency can be found. At TEI’08 he gave already a nice private demo on how this can be linked to mobile devices and how to use a off-the-shelf phone with an accelerometer as controller.

On Sunday afternoon I flew to Florence and we met up in the evening with former colleagues – CHI always feels like a school reunion 😉 and it is great to get first hand reports on what everyone is working currently. On the plane I met Peter Thomas (editor of Ubquitous Computing Journal) and we talked about the option of a special issue on automotive…

We have rented a house in the Tuscany Mountains together with Antonio’s group and collaborators from BMW research and T-Labs. Even though we have to commute into Florence everyday it is just great that we… Continue reading

The last 3 days we were at the German HCI conference (Mensch und Computer) in Weimar. Overall the conference had a really interesting program (21 papers with an acceptance rate of 30%), presentations from usability professionals and a number of workshops.

Dagmar Kern presented our research on improving in-car telecommunication that was carried out together with people from BMW group in Munich. For details see:Dagmar Kern, Albrecht Schmidt, Michael Pitz, Klaus Bengler. Status- und Kontextinformationen für die Telekommunikation im Auto. Mensch & Computer 2007. Weimar, September 2007.Heiko Drewes showed the initial results of the studies on… Continue reading

While waiting in Stuttgart in the lounge of the railway station I picked up a paper called “Auto-Bild” (the selection of magazines is really poor 😉 and I found an interesting news item in it.

KIA has done a survey (with over 2000 people) in the UK on decision making in the car. It appears that people use the time in the car to discuss major issues in their lives and that they make significant decisions during long journeys. I have not found the original survey from KIA but there are several pages that discuss the results, e.g. gizmag.… Continue reading

Today Karl-Heinz Sylla and Reinhard Budde (both senior researcher at Fraunhofer IAIS) gave for the summer research project a tutorial on agile methods for software engineering. The experience they have from large scale real world projects is impressive! We looked at different approaches to software construction and discussed the pros and cons. Short iterations, user stories, pair programming and test driven development seem to fit very well to our work approach and project goals. A good starting point for more on the topic in particular with a teaching perspective are the following 2 papers: LeJeune, N. F. 2006. Teaching software… Continue reading
