Florian Alt back from the US – and now with us in Essen

admin Schreibe einen Kommentar

Florian Alt studied media informatics at the LMU in Munich and has now joined our group. In Munich he worked during his project thesis with me on how to improve hospital work in pervasive computing technologies [1]. Last year he came to Fraunhofer IAIS and did his master thesis (a annotation system for the WWW based on the UsaProxy, http://fnuked.de/usaproxy/). Before joining us he worked for some months in New York setting up an IT department for a German company that opened a branch in the USA… we are happy for the brain gain 😉

Humangrid – are humans easier to program than systems?

admin Schreibe einen Kommentar

In the afternoon I visited humangrid, a startup company in Dortmund. Their basic idea is to create a platform that offers opportunities for crowdsourcing – basically outsourcing small tasks that are easy to perform by humans to a large number of clickworkers. One example for such a scenario is tagging and classification of media. It is interesting that they aim to create a platform that offers real contracts and provides guaranties – which makes it in my eyes more ambitious than Amazon’s Mechanical Turk.

One interesting argument is that programming humans (as intelligent processors) to do a certain task that involves intelligence is easier and cheaper than creating software that does this completely automated. Obviously with software there is nearly zero-cost for performing the tasks – after the software is completed, however if the development costs are extremely high paying a small amount to the human processor for each task may still be cheaper. The idea is a bit like creating a prototype using wizard of oz – and not replacing the wizard in the final version.

In our discussion we developed some idea where pervasive computing and mobile technologies can link to the overall concept of the human grid and crowdsourcing creating opportunities for new services that are currently not possible. One of our students will start next month a master thesis on this idea – I am already curious if we get the idea working.

Tanja Döring joined our group

Today Tanja Döring started with our group in Essen. She did her MSc at the University of Hamburg with Steffi Beckhaus and Horst Oberquelle. I met her first last year at TEI’07 in Baton Rouge, where she presented work on a table for art historians [1]. This year Tanja was a student volunteer at TEI’08 in Bonn.

Finishing the course User Interface Engineering for this term

admin Schreibe einen Kommentar

No we had the last lectures of the course User Interface Engineering for this term. We will have oral exams stating later this month. The whole set of slides I used over the term (a bit more than 800) are available on our website. This year we have the first time made a set of questions to assist revising the material. In total we have about 200 questions – and looking over the questions it is really interesting that user interface design is not as trivial as one thinks (after teaching it for several years 😉

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!

Deadline for Summer@IAIS soon

admin Schreibe einen Kommentar

Not much time left to apply for the student research project. From 20.8. to 30.9.2007 we plan to design and implement a new specific search engine. The program is open to all computer science and media informatics students, primarily in Germany. We assume it will be very competitive. For accepted students we provide a HIWI-job at Fraunhofer IAIS for the 5 weeks. It will be possible to get credits for the course (IPEC lab course at the University of Bonn).

For more information please see: www.iais.fraunhofer.de/summer2007.html

Interaction Ivrea

admin Schreibe einen Kommentar

Pascal Bihler send me today a link to an interesting teaching/research project at Ivrea (http://courses.interaction-ivrea.it/strangely/). The assignment is to think how a common artefact can be enhanced with digital technology. The results of the exercise are quite impressive. It seems that Interaction Ivrea is now somehow integrated into the Domus Academy in Milan.

When I was at Ivrea in November 2003 for the Jamboree of the disappearing computer initiative it was amazing to see the level of creativity – from the Ivrea design institute as well as from the various European projects in the disappearing computer program.

There at Ivrea I also met a really amazing person who has greatly influenced interaction design in the last 20 year: Gillian Crampton Smith. She was the founding director of the institute in Ivrea and has moved on to Venice (IUAV).

Pervasive Computing and Ethics

admin Schreibe einen Kommentar

Together with Boriana Koleva I organized the doctoral colloquium at Pervasive 2007 in Toronto. We had 9 students presenting and discussing their PhD work with us.

One central observation was that we come to a point where we have to make more and more ethical decisions. Many things that are technical feasible and harmless within the lab may have sincere implications in the real world. If technologies for tracking, tracing and mining (e.g. social network analysis, location based services, context-aware systems) are deployed beyond the lab the question of choice becomes a real issue – are users aware of it and can they opt-out?

In the area of context-awareness technology has moved on since I started my PhD on the topic nearly 10 years ago – but amazingly scenarios did change little. Automatically detecting a meeting is still on the students slides. The more I learn and understand about context-awareness the more it becomes apparent that this apparently simple use case is amazingly hard!

Lecture at CDTM in Munich

admin Schreibe einen Kommentar

The CDTM is a joint elite study program from LMU Munich and TU Munich (http://www.cdtm.de/). It offers a set of complementary course for students from different backgrounds including math, business studies, engineering, computer science and media informatics. In their course on multimodal HCI I gave today an introductory lecture on the motivation for and the basics of user interface engineering.

In the seminar room was a real typewrite – in fact a travel type write. It was a real good prop to discuss micro- and macro-efficiency.

One question about the sustainability of a competitive advantage based on user interfaces made me really think. As the user interface is visible it is really hard to protect the competitive advantage and IPR are difficult on this topic. Desktop GUIs are a good example how quickly ideas propagate between competing systems. The only real option to maintain a competitive advantage is to continuously innovate – keeping the status quo means falling behind. The fact that one can not keep new user interface concepts secret (if one includes them in a product) is one of the most exciting aspects of user interfaces research – it is fast moving because everyone shows off their results!
