Visit at the University of Hamburg

admin Schreibe einen Kommentar

Yesterday we visited the computer science department at the University of Hamburg. Prof. Oberquelle und Beckhaus had invited me at the Mensch & Computer conference to visit them and give a talk about our work.

Before the seminar we had a chance to see the lab of Steffi Beckhaus. I have tried the ChairIO – and it was fun. They sound floor creates a really interesting experience (similar to the butt-kicker just more intense). We could also play with GranulatSynthese and try the smell user interface (apple smell is absolutely convincing, not sure about some of the others).

We had some discussion on emotions and capturing physiological parameters. Thinking about emotions and senses with regard to a community sharing them opens up a lot of potential for new experiences and potentially applications. We discussed this topic to some extent some weeks ago at the Human Computer Confluence Workshop in Brussels. I really thing a small scale experience in share emotions could move us forward and provide some more insight. In Hamburg they have the NeXus-system (perhaps we should get this too and create a networked application).

In my talk (creating novel user interfaces) I focused on the PhD work of Paul Holleis (KLM for mobile phones, his CHI Paper from last year) and of Heiko Drewes (Eye-Gestures, his Interact’07 paper). The discussion was quite interesting.

Interesting MSc Dissertations at Trinity in Dublin

I have been at Trinity College in Dublin today as external member of the MSc exam board. While reading MSc dissertations I learned at lot of interesting things. Here are two pointers to technologies which I like to share (they may be useful in further projects):

SUMO – Simulation of Urban Mobility: An open source traffic simulation package

Slowly settling in

admin Schreibe einen Kommentar

Time is flying. We are nearly one month in Essen. Teaching started well and quite a number of students came to our course (see http://www.pervasive.wiwi.uni-due.de/en/teaching/). We have a reliable Internet connection and more furniture than we need 😉 Starting from scratch is a great experience – especially as everybody was very helpful.

Nevertheless it takes a lot of time and effort. I am extremly happy that I was able to start with a real team (Dagmar and Paul)!

In Search of Excellence

admin Schreibe einen Kommentar

At the Fraunhofer retreat in Westerburg we had very interesting discussions on research and research strategies in computer science. The span of excellent research in computer science is enormous ranging from theoretical work (e.g. math style proofs), to engineering type work (e.g. systems), to experimental and empirical work (e.g. studies). This makes it really challenging to find a common notion of “excellent research”. This reminds me of an interesting book which I started to read (recommended to me at the retreat): In Search of Excellence: Lessons from Americas Best Run Companies by Robert H Waterman et al. – so far it is really interesting to read. However everything in management seems really straightforward on paper – but in my experience in the real world it always comes down to people.

Guest course at the University of Linz, MSc Pervasive Computing

admin Schreibe einen Kommentar

I am teaching a guest course at the University of Linz in the Pervasive Computing master program. The topic is Unconventional User Interaction – User Interfaces in a Pervasive Computing World (http://www.ubicomp.net/uui). Today we started with an introduction to motivate how pervasive computing changes human computer interaction. I am already looking forward to the projects!

At dinner I learned why you can never have enough forks in a good restaurant. In case you loose your pen for the mobile phone a fork will do… The topic of the lecture is everywhere!

Information inside the cap

Travelling on the train from Crailsheim to Nürnberg I saw several police officers on their travels back from an assignment at Stuttgarter Volksfest. When we got off the train the collected their caps from the luggage rack and observed an interesting (traditional) information display.

Inside the cap they carried a schedule and a description of the location they had to go. The size of the paper-display was about 15 x 15 cm. It seems an interesting place to display and access information – perhaps we will do a digital version of the cap as an assignment in our courses.

Moving to the University of Duisburg-Essen

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 interfaces and novel applications in the domain of pervasive and ubiquitous computing.

UbiLog Workshop in Bremen

This afternoon our UbiLog workshop was held in Bremen as part of the Informatik 2007 conference. We selected 4 papers for presentation and had a lively and interesting discussion.

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 this experience in the design of secure systems.

Prof. Gerhard Krüger made honorary member of GI

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.
