Satellite Television –Challenges

My first day of the holidays I got myself into an interesting project – setting up a satellite dish that receives Astra 19.2 (German TV) and Astra 28.2 (major UK TV stations). Going back between my roof and living room I finally got it to work – thanks to many posts on the Internet. That brings me back to a question I ask myself more and more (not just for setting up TVs): how did people share technical and practical information before the Internet? It seems that the Internet really is a catalyst for implementation.

After having the hardware in place (which is more difficult than the theory of pointing it at a certain angle – especially without the right tools) I was surprised by the number of channels and the user interfaces of the digital sat receivers. It seems that much of the usage and interaction concept is still from a time where there were 3 channels – youtube is much easier to use… Perhaps satellite television could provide a much more exciting experience with new means for interaction (perhaps those devices are out there an I just got the poor ones).

Deadline for Summer@IAIS soon

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).

acatech workshop: object in context

It was interesting to see that smart objects / smart object services, context, NFC, and RFID become very mainstream. It seems that nearly everyone buys into these ideas now.

Dr. Mohsen Darianian (from Nokia Research, same building as Paul Holleis is at the moment) showed an NFC-advert video which reminded me on the results of an exercise we did on concept videos within an HCI-class at the University of Munich 🙂

Overall it seems that acceptance and business models are of great interest and that to create them a lot of technical insight is required. The issues related to user interfaces, interaction, experience become central factors for the success of products and services.

One discussion was on the motivation for people to contribute (e.g. user generated content, write open source code, answer questions in forums, blogs). Understanding this seem crucial to the prediction whether or not a application is going to fly or not.

Besides contributing for a certain currency (e.g. fame, status, money, access to information) it seems that altruism may be an interesting factor for motivating potential users. Even if it is a low percentage within our species the absolute number on a world wide scale could be still enough to drive a certain application/service. There is interesting research on altruism in the animal world (or at the researchers page http://email.eva.mpg.de/~warneken/ ) maybe we should look more into this and re-think some basic assumptions on business models?

Our break out group was in the rooms of the Institute of Electronic Business e.V (http://www.ieb.net/). It is a very pleasant environment and their link to the art school reflects very positive on the atmosphere and projects. The hand drawn semacodes were really impressive.

Lecture at CDTM in Munich

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!

Our Presentations at CHI’07 in San Jose

At this years CHI the Conference on Human Factors in Computing Systems we presented 3 contributions: a full paper, a CHI-note, and a work in progress paper. Have a look at them!

Lab started: Developing Interactive Mobile Applications

Our Lab course on „Developing Interactive Mobile Applications“ started today with 11 students (the limit was 8 – but 3 more is OK as we got some additional phones from Nokia).

Shortly after lunch everyone had there first application written and deployed to the phone. In the afternoon we looked into sending an SMS from JAVA using the messaging API…. And this is fairly easy.

For more details on the course see: http://uie.bit.uni-bonn.de/developing.php

Seeing the possibilities of JAVA ME and how quick people get applications running made me wonder how long it takes till we have massive mal-ware, viruses and spam on the phone. Secutity on phones may be one of the upcomming challenges.

Educational Fair in St. Petersburg


Together with Alexandra Reitelmann I am in St. Petersburg (Russia) to advertise our study programs at the B-IT and University of Bonn (http://www.bit.uni-bonn.de/). In particular we talk to potential students about the master programs in Media Informatics and Life Science Informatics. The educational fair is held in the centre of St. Petersburg at the Russian Museum of Ethnography, which is a truly magnificent building. Overall I was surprised by the city, the buildings, the shops and the quality of the hotel.

The discussions with potential students and in some cases with their parents were interesting. It showed that there is a demand for high quality education and that Germany is an attractive place to study. Given the background of many people we talked to it could be interesting to look into the potential of a conversion master in media informatics, where people with different degrees (e.g. psychology, business studies, math, or engineering) can enter. In comparison to other countries education seems to be a bargain in Germany.

Tangible and Embedded Interaction 2007

Just a little more than week before the Tangible and Embedded Interaction 2007 starts in Baton Rouge (http://www.tei-conf.org/).

The program looks really exciting – a mixture of computer science, HCI, design, and art. I would expect that the conference sparks a lot of new ideas. Brygg Ullmer did the cover for the proceedings and it looks really cool.

Having seen the program of TEI’07 we have decided to put in a proposal to run the conference next year in Bonn. Hope we get it…
