Today former colleagues from Fraunhofer IAIS visited the faculty of economics and computer science here in Essen. It was amazing how many topical connections we found between the research at IAIS and the work that is going on here in business studies, information system, and computer science. We discussed different options for future cooperation – in research and teaching – and I am very hopeful that we create interesting opportunities.

Last year, while still in Bonn, I organized summer @ IAIS. For this year we may go more interdisciplinary and set ourselves high goals… lets see.

The week before Easter is the traditional time for the meeting of the GI group university professors (GIBU). GI (Gesellschaft für Informatik) is similar to the ACM, but on a national level. Due to other time constrains I was only able to be there for two days. We see that political aspects play more and more a role in our daily work life – if we like it or not it becomes essential to express our views with regard to computer science in Germany from a university perspective.

Besides this Dagstuhl (and in particular the wine cellar)… Continue reading

The picture does not show a research prototype – it shows the actual interior of a 5-series BMW (fairly recent model). The driver (an elderly lady) adapted the UI to suit her needs. This modification includes the labeling of controls which are important, writing some instructions for more complicate controls close to them (hereby implementing one of the key ideas of embedded information [1]), an covering some to the user “useless” controls.

At first I assumed this is a prank* – but it seems to be genuine and that makes it really interesting and carries important lessons with regard to… Continue reading

After having frost and snow yesterday morning in Germany being in Porto (Portugal) is quite a treat. The KDubiq application workshop is in parallel to the summer school and yesterday evening it was interesting to meet up with some people teaching there.

The more I learn about data mining and machine learning the more I see even greater potential in many ubicomp application domains. In my talk “Ubicomp Applications and Beyond – Research Challenges and Visions” I looked back at selected applications and systems that we have developed over the last 10 year (have a look at the… Continue reading

After inspiring discussions during the workshop and in the evening I reconsidered some ideas for automatically generated tutorials by user interaction. The basic idea is to capture usage of applications (e.g. using usa-proxy and doing screen capture) continuously – hard disks are nowadays big enough 😉 Using query mechanisms and data mining a user can ask for a topic and will then get samples of use (related to this situation). It creates some privacy questions but I think this approach could create a new approach to creating e-learning content…. maybe a project topic?

This morning I presented a short talk on new ways for outdoor advertisement at CeBIT. Based on results from interviews we know that shop windows and billboards are a well received medium. Similarly to measures we know from web logfiles I argue that it is interesting to have similar information on visitors, views, returns, durations for real world adverts.

The general approach we suggest is to use senor to measure activity – and as such measurements are incomplete there is need for data analysis and models. In two examples I show how this can be done using Bluetooth as… Continue reading

The proceedings of the 2nd international conference on Tangible and embedded interaction are online in the ACM digital library. Still not in the search index and with a few corrections to do…

Hiroshi Ishii contributed a paper on “Tangible bits: beyond pixels” – the first paper in the proceedings [1] and a great overview and introduction to the topic. If you are a student to start on tangible interaction or if you have students that start this paper is a mandatory reading!

Yesterday afternoon I was in Hannover at CeBIT to set up our part in a demo at the Fraunhofer stand (Hall 9, Stand B36). The overall topic of the fraunhofer presence is “Researching for the people“.

After some difficulties with our implementation on the phone, the server and the network (wired and wireless – my laptop showed more than 30 wifi-accesspoints and a BT-scan showed 12 devices) we got the demo going. The demo is related to outdoor advertisement and together with Fraunhofer IAIS we provide an approach to estimate the number viewers/visitors. On Wednesday I will give… Continue reading
