Merry Christmas 2016
Look inside your envelope,
the Christmas card should have them all:
Wooden wheel, a snowflake, too.
Copper things, we have a few.
Resistor, light, they’re all brand new,
a paper cut out with a view.
To bring the gift of light,
for every winter night.
You will need the following pieces for the first assembly part:
four copper strips (two long, two short), LED, resistor, wooden rim, wooden plug and the black piece of paper.
Slide in the LED,
into the holes that be.
Long leg positioned through the oak,
on the left… Continue reading
Florian Alt defended his PhD thesis “A Design Space for Pervasive Advertising on Public Displays” at the University of Stuttgart. Over the last years Florian work at the crossroads of interactive public displays and pervasive advertising. His research output during the last years and while working on the http://pd-net.org project was amazing, see his DBLP entry.
The dissertation will be soon available online. If you are curious about his work right now, there are a few papers or a book you should read. A high level description of the findings is described in a paper published in… Continue reading
Every day per year one place or institution is Germany is awarded “a place in the land of ideas“. This initiative is quite completive (each year well over 2000 institutions apply and the year has only 365 days…).
The innovation factory at the University of Duisburg-Essen has a really interesting vision and received the award for its concept of converting ideas into innovations and products. It promotes thinking in product rather and by this challenges researchers to look how their research results could enable new products or enhance existing products. I find this a most useful exercise –… Continue reading
One trend that can be observed is that researchers move beyond the living lab. In the discussion it became apparent that living labs can start research efforts in this area and function as focus point for… Continue reading
This morning a new working group on tangible interaction in mixed realities (in German Be-greifbare Interaktion in Gemischten Wirklichkeiten) was established as part of the German Computer Science Society (GI). About 30 people from all over Germany gathered at B-IT in a pre-conference event to TEI’08. The group was interdisciplinary, including computer science, design, psychology, and pedagogic. The diversity of research projects as well as teaching programs in Germany in impressive.
My talk was entitled “back to the roots – technologies for interweaving learning and experience”. I stared out with the question: What is the difference between an apple tree and a biology book. In essence my argument is that (1) first hand experience can not be replaced, (2) we need consolidated knowledge based on the experience to learn efficiently, and (3) pervasive computing technologies can bridge the gulf between… Continue reading
The Fraunhofer institute IAO opened today a new interaction lab in Stuttgart under the topic interaction with all senses. Prof. Spath, director of the Fraunhofer IAO, made a strong argument for new user interfaces. In his talk he discussed adaptive cruse control in cars as an example for user interface challenges.
My talk on “implicit interaction – smart living in smart environments” argues for a sensible mix of user centred design and technology driven innovation. As one example I used the Sensor-Knife which Matthias Kranz implemented.
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.
We visited the archeology and Stone Age museum in Bad Buchenau http://www.federseemuseum.de/. For our visit we rented their audio guide system – they had one version for kids and one for adults. The audio guides were done very well and the information was well presented.
Nevertheless such devices break the joint experience of visiting a museum! We had three devices – and we stood next to each other listening but not talking to each other. Even though it may transport more information than the written signs it makes a poorer experience than reading and discussing. I wonder how one… Continue reading
The internatonal conference on pervasive computing in Toronto had an exiting program.
The keynote was by Adam Greenfield on “Everyware: Some Social and Ethical Implications of Ubiquitous Computing” – matching a number of issues we discussed the day before at the doctoral colloquium. The talk was enjoyable even though I think some of the statements made, in particular with regard to opting out and informing the users (e.g. logos) are over-simplified. Furthermore the fact that our society and its values are changing was very little reflected, e.g. privacy is not a constant.
The best paper (by Rene Mayerhofer and Hans… Continue reading
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!

In the castle on campus Ute Schütz and Michael Krapp from IAIS and SCAI organize a public panel discussion on citizen journalism and Web 2.0 trends. The discussion looked at the topic from several angles including technology, content, and communication. I had the honour to be on the panel with Wolfgang Back, Frank Patalong, Moritz „mo.“ Sauer and Thomas Tikwinski.
On issue was how much blogs are (mis)used to transport information or to do advertising. The web seems to be to many people a very believable medium. This reminded me of an article I read some time ago on story-telling… Continue reading
In Germany there are still too few girls and women interested in studying technical subjects – it may have different reasons but I think trying to convince young girls that technology is really exciting is a good way of addressing the problem.
We had this morning 7 girls visiting our lab. Matching our current teaching at B-IT (and using the test implementation Dagmar made 😉 we offered the topic “The computer knows where I am – how does this work”. First we played a mini geocaching game where they had to find a bag of jelly babies behind the castle.… Continue reading
Debora Estrin made an interesting statement. The “early challenges” (the thousands or millions of randomly scattered sensor notes) do not have much applicability outside the battlefield. The new challenges are heterogeneity (specific sensors with specific capabilities) and interactivity (basically sense-making is a process where humans are involved). She made the point that the logical consequence is that dealing with data is the essential issue and statistics have an increasing role. Furthermore these new research directions make a stromg call for application driven research. With these very insightful comments she criticised a lot of the current work in sensor networks. Especially… Continue reading
Gregor got for our Perci prototype (Supporting Mobile Service Usage through Physical Mobile Interaction) the best demo award. So it paid off that he spend a night configuring the data services on the phones for the US networks 😉 It is amazing that it is still quite an effort to configure data services for a new provider.
This year we (my previous group from LMU Munich) have a significant presence at PerCom. Form the 20 full papers the Embedded Interaction Research Group (www.hcilab.org) has 3, and additionally 1 of the 7 concise papers is from us. With a total of 207 submissions and an acceptance rate of around 10% this is quite an achievement for the team – and a good high point for the project before moving it to University of Bonn.
At PerCom 2007 (www.percom.org) Florian Michahelles (Auto-ID labs, ETH Zurich), Frédéric Thiesse (University of St. Gallen), John R. Williams (MIT Cambridge) and I are running the the PerTec workshop (www.autoidlabs.org/events/pertec2007). There is quite some interest in the topic and the range of topics is from technical to user interface and security.
In contrast to the workshop 1 year ago at Pervasive 2006 it seems that item level RFID-tagging is undisputed and that the only discussion point is when it is coming – in 6 month or 10 years. There is also still some discussion about what… Continue reading
At the Fraunhofer Forum at CeBIT I had the chance to talk about future transport solutions. One of my students in Munich (Michael Müller) is working on a pro-active transport container. In the project aware-goods (http://www.comp.lancs.ac.uk/~albrecht/awaregoods/) we looked into this domain already in 2000 at TecO together with SAP Research. Reiterating over the idea is really interesting as now the technology is really here – sensor network nodes are available, mobile phones offer massive processing power, there is ubiquitous data connectivity, and web service interfaces are available for many applications.
The big question is now on algorithms and… Continue reading
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… Continue reading
The second international conference on Tangible and Embedded Interaction (TEI’08) will be in Bonn, Germany. Together with Hans Gellersen from Lancaster University I will chair the conference in 2008. I am absolutely delighted that Elise van den Hoven from Eindhoven University of Technology and Ali Mazalek from Georgia Institute of Technology will co-chair the program. The conference will be held in the B-IT-Center in February or March 2008 – we will soon put more information on www.tei-conf.org
Some thoughts to keep in mind for 2008… In the discussion it was suggested that we capture the conference next year on video… Continue reading
Thecla Schiphorst introduced us in her talk “PillowTalk: Can We Afford Intimacy? to the concept of Affectionate-Computing.The central question is really how can we create intimacy in communication an interaction with and through technology? The prototype showed networked soft objects, that include sensors that recognize tactile qualities and gesture interaction. There are more details in her paper published at TEI’07.
The paper is available at http://ubicomp.lancs.ac.uk/~villar/publications/pdf/voodooflash_tei.pdf

A central lesson from his talk for me is to look more closely how to design interactive systems so that people can exploit the technical weakness of system creatively. We will always have to deal with sensors systems, context-recognition, and learning algorithms that are not 100% perfect. I find it interesting to see this rather as a resource for design than a problem. The experience Tom reported from… Continue reading
We got the message that our workshop proposal at the German Informatik2007 Conference is accepted. Together with colleagues from the University of Bonn and from the AutoID-Labs in Zurich I will organize a workshop on context-aware and ubiquitous computing applications in logistics. With the workshop we hope to get together interesting people who look into smart transport and logistics solutions.
The Workshop webpage is online at: ubilog.iai.uni-bonn.de and papers are due at 29.04.07. I am really looking forward to seeing the submissions.
