From Monday on I will be at the University of Duisburg-Essen. After a little less than a year in Bonn a new challenge is ahead: setting up a new group on Pervasive Computing and User Interface Engineering. The lab will be situated at the campus in Essen (Schützenbahn 70) in the heart of the city. Our group will be in the Institute for Computer Science and Business Information Systems in the faculty of Economics. Teaching starts in the winter term with a lecture on User Interface Engineering and several project oriented courses.
The focus will be on systems, user… Continue reading
Following the talk of Nikolai Krambrock we discussed the use context, and in particular location, to restrict or allow access to information. My favourite example is an online-banking appliance that only works in predefined areas (e.g. at home and in my car). Using context appears one option in creating human understandable solutions for secure systems. People have developed means to protect physical objects and valuable, perhaps we should draw more on… Continue reading
At the dinner of this yeas GI conference Professor Gerhard Krüger became the 6th honorary member of the German Computer Science Society (GI, Gesellschaft für Informatik). He was one of the people who understood very early that computer science is a central topic and pushed in the 1980ies form higher capacities in computer science at German Universities.
When I was at Karlsruhe (1998-2001) he was my supervisor and taught me a lot! In short: invest in the development of people.
We tried to explain the idea of ubiquitous computing to journalist and it seems they got the idea. And hence Ubicomp 2007 was featured in the Austrian Press:
- Mitdenkende Gegenstände – Allgegenwärtige Technik (ORF)
- Der Computer ist immer und überall (der Standard)
Ubicomp 2008 will be in Korea.
Alireza Sahami presented our CardiViz project at the demo session at Ubicomp. We were very happy that the project that was the result of our IPEC course on developing mobile applications was accepted as a demo.

Jonna Häkkilä, Anind Dey, Kari Hjelt, and I organized organized the Ubiwell workshop (Interaction with Ubiquitous Wellness and Healthcare Applications) at this years pervasive. Alireza presented another paper on heartbeat monitoring there:Florian Alt,… Continue reading
It is often discussed whether or not the user interface in the car matters or not. The basic argument is that cars are emotional and hence the driving experience matters and everything else is secondary.
However it seems the user interface becomes more and more part of the experience. On Saturday night I travelled via Munich to Innsbruck – and had again some time on in the lounge at the railway station. In a article on the new VW concept car UP it was interesting to see that about 15% of the text (about 20 lines text of the whole… Continue reading
Heiko Drewes and Richard Atterer, collegues from university of Munich, have travelled to Interact 2007. Their emails indicate that the conference is this year at a most interesting place. The conference is in Rio de Janeiro, directly at the Copacabana. The conference was highly competitive and we are happy to have two papers we can present there.
Heiko presents a paper that shows that eye gestures can be used to interact with a computer. In his experiments he shows that users can learn gesture with eyes (basically moving the eyes in a certain pattern, e.g. following the outline of a… Continue reading
Some weeks ago Ben Sutherland from The Economist called. He was researching for an article discussing the computing revolution over the last 25 years. In his research he to talked to many different people (from different countries, different fields, different views) and was particularly interested in applications that will come in the future and with me in particular on the concept of context-awareness.
The article “The trouble with computers” appeared 6th of September and discusses a mix of ideas and viewpoints. We talked about 30 minutes on the phone and I am quite surprised what statement he picked… Continue reading
In the school museum I came across two very simple pen-based computing aids. The devices are very simple mechanical tools that help to do addition and subtraction. It was called ADDIATOR.
The utility is limited to addition and subtraction and it provides a very simple mechanism to deal with carry-over. If the number which is to be moved is white the calculation is without carry-over and one pulls it down. If the number is red then there will be a carry over one has to pull up and around the semi-circle (this is the mechanism for carry over). A… Continue reading
After my daughter started school on Saturday we visited a historic school on Sunday. Comparing teaching materials is interesting. Especially providing up to date information in geography must haven quite a costly task. Many expensive charts and maps that were printed on canvas are now freely available in digital form. It seems that instead of having a film project, a slight projector, an overhead projector and canvas displays a computer and projector with internet access will do. Similarly having stamps to reproduce maps seems like ancient history, even though it has been still in use 20 years ago.
However I… 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
At the German HCI conference (Mensch und Computer) I organized together with Paul Holleis and Klaus Bengler (BMW Group) a workshop on automotive user interfaces. We were surprised how many people work and research in this area in Germany and Austria.
The 9 talks showed a wide range of research results and questions ranging from activity recognition, search interfaces, cultural issues to research methods. Dagmar Kern presented our work on a new method for interviewing drivers at the gas station. Stefan Graf from BMW groups had an interesting demo on object oriented interaction and in-car text input.… Continue reading
Even though the screen is very small it shows again that one needs little to create the illusion of a movie. In the end it… Continue reading
It looks like pixels and is abstract in comparison to the other windows (which have traditional picture motives). To me it seems a neat idea that somehow reflects our time.
