Currently we have an assignment in our Pervasive Computing class that asks students to design and develop a system where actions are associated with artifacts. Technically students should develop a web based solution using RFID. Apropos RFID, … if you look for a good introduction on RFID read Roy Want’s IEEE Pervasive Magazin paper [1].

We use the hardware from http://nabaztag.com/ (Ztamp:s and Mir:ror) as the focus is on the concept and application and not on the underlying technology. To ease development Florian and Ali have developed a little system that offers WebCallBacks (students can register a URL and that… Continue reading

Pervasive 2009 had a really exciting program and provided a good overview of current research in pervasive and ubiquitous computing. Have a look at the proceedings of the pervasive 2009 conference. The Noh theater in Nara was a very special and enjoyable venue and it was organized perfectly – as one would expect when travelling to Japan.

The idea of having short and long papers together in the main track worked very well in my view. The number of demos and posters was much higher than in the years before – and that was great and very inspiring. Have… Continue reading

We organize at this year’s Pervasive computing conference in Nara, Japan a workshop on Pervasive Advertising – http://pervasiveadvertising.org.  We expect that there is a lot of interesting research going on in the area and it is clearly a controversial topic. Being an optimist – I see the new options that arise. In particular a future with less annoying advertisements is one hope 🙂 But many people are focusing on the risks that arise – an interesting positing with some criticism of our workshop objective can be found at the near future laboratory  I do not… Continue reading

The PC meeting for Percom 2009 took place at IBM in Hawthorne, NY. Percom had about 200 submissions and many good ones – so we could compile an exciting program across the whole field of pervasive computing and communication. As one of three program vice chairs I have looked in detail in about 1/3 of the submissions that were application related. It is interesting to observe that research as a whole in the field becomes more major and at the same time more incremental. 

To me this puts up the big question in which domains will the new big… Continue reading

Christofer Lueg (he is professor at the School of Computing & Information Systems at the University of Tasmania) and Trevor Pering (he is a senior researcher at Intel Research in Seattle) visited our lab this week. The timing is not perfect but at I am not the only interesting person in the lab 😉

Together with Roy Want and others Trevor published some time ago an article in the IEEE Pervasive Magazine that is still worthwhile to read “Disappearning Hardware” [1]. It shows clearly the trend that in the near future it will be feasible to include processing and wireless… Continue reading

Over the last years there have been many workshops and sessions in the ubicomp community that address the evaluation of systems. At Pervasive 2005 in Munich I co-organized a workshop on Application led research with George Coulouris and others. For me one of the central outcomes was that we – as ubicomp researchers – need to team up in evaluating our technologies and solutions with experts in the application domain and that we stay involved in this part of the research. Just handing it over for evaluation into the other domain will not bring us the insights we need to… Continue reading

What is a birthday cake without a candle? Sometimes it is hard to find a candle but having a creative team there is always a solution – less than 3 minutes away 😉 As always with new technologies – after deployments ideas for Version 2 (which will include much more functionality) emerge… An there was another business idea – interactive wedding cakes – perhaps we explore this later this year 😉

I had a day off an was as “teaching assistant” on a school trip with the kids my wife is teaching. The trip went to a museum village (Wackershofen), which tries to preserve and communicate how people lived about 100 years ago.

On side observation was that in digital photography the limiting factor is now not anymore the memory space but the batteries in the camera. This has changed over the last 2 years – there children still selected which pictures they have to delete – now that is no issue anymore. This shows that some of the trends… Continue reading

Using electrodes to detect eye movement and to detect reading [1] – relates to Heiko’s work but uses different sensing techniques. If the system can really be implemented in goggles this would be a great technologies for eye gestures as suggested in [2].

Utilizing infrastructures that are in place for activity sensing – the example is a heating/air condition/ventilation system [3]. I wondered and put forward the question how well this would work in active mode – where you actively create an airflow (using the already installed system) to detect the state of an environment.

Further interesting ideas:

Paul presented after lunch our full paper on a development approach and environment for mobile applications that supports underlying user models [1]. In the paper he shows how you can create applications while programming by example where the development environment automatically adds a KLM model. In this way the developer becomes automatically aware of estimated usage times for the application. The paper is work that builds on our paper on KLM for physical mobile interaction which was presented last year at CHI [2]. The underlying technology is the embedded interaction toolkit [3] – have a look – perhaps it makes… Continue reading

This morning the pervasive 2008 conference started in Sydney. The conference hotel is in the heart of the city at Darling Habour. As in recent years the conference is very competitive (acceptance rate of about 16%) and features interesting technologies and high quality research. The program with links to Springer-Link is available at http://www.pervasive2008.org/Program/ One presentation included a slide with a quote about the technology he created in the project – will not tell which paper/author it is. Look in the proceedings and pick your favorite. This quote seems questionable at first – but it describes the essence in the… Continue reading
Today we had our Pervasive at home workshop – as part of Pervasive 2008 in Sydney. We had 7 talks and a number of discussions on various topics related to smart homes. Issues ranged from long term experience with smart home deployments (Lasse Kaila et al.), development cycle (Aaron Quigley et al.), to end-user development (Joëlle Coutaz). For the full workshop proceedings see [1].

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

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

Elise van den Hoven, the program co-chair of TEI08, organized the printing of the proceeding. We went there on Tuesday to collect the books – quite a heavy load! The books look really good and the cover is great.

In the afternoon I gave a lecture with the title “Interacting with Pervasive Computing Systems”. I have related some of our recent work and ideas to the focus of the course which is “intelligent systems, products and related services”. In particular I asked to re-think how we can find a balance between user needs and technology push – without… Continue reading

In contrast to us people in the medical domain seem to start early in the morning. In the process of preparing a project proposal we visited the Elisabeth Hospital in Essen. We got the chance to see some invasive heart exams first hand.

It is impressive how well such complex processes run and how quick the staff can assess the conditions. Looking for potential to make theses processes easier is a touch challenges – espcially if you do not do this by sitting at your desk but if you want it to be realistic. In the discussion with the head… Continue reading

Gabi Kotsis produced at dinner one of the rarest bottles of wine – an original Pervasive 2004 wine (Alois Ferscha had it made extra for the conference and he designed the label, too) – and she opened it!

The wine is great. It brought back some memories of a very intersting doctoral colloquium in Linz and a splendid conference in the Vienna Hofburg with an excellent scientific program. Somehow I remember that after one evening (and some conference wine) I agreed to run Pervasive 2005 in Munich…

As we have quite a good number of registrations for TEI’08 in… Continue reading

The Pervasive 2008 TPC meeting on Saturday was held distributed over 3 continents and linked via video conference. In Germany we had a really good time slot (12:00 to 20:00) – Australia and California had a really late/early day.

The meeting worked well over video and considering the saved travel time it seems this is a acceptable alternative to a full physical meeting. It was interesting to see that the video conferencing quality did not really improve much over the last years. We ran the TPC meeting for Ubicomp 2003 between the UK and the USA also with a video… Continue reading

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… Continue reading

Today I finally got around visiting Jan Borchers (media computing group at RWTH Aachen). Tico Ballagas hat as part of his PhD defence a public talk and took the chance to go there.

There where new parts in the talk on the impact of the selection space resolution on Fitts’s law that I had not seen in his work before. It is published in 2006 as a technical report (Rafael Ballagas and Jan Borchers. Selexels: a Conceptual Framework for Pointing Devices with Low Expressiveness. Technical Report AIB-2006-16, RWTH Aachen, Dec 2006) which is worthwhile to have… Continue reading

This morning I corrected the proofs for the Pervasive and Mobile Compting journal for the paper I had together with Lucia Terrenghi at Percom (Methods and Guidelines for the Design and Development of Domestic Ubiquitous Computing Applications, Proceedings of the Fifth Annual IEEE Conference on Pervasive Computing and Communications (PerCom), New York, NY, USA, Mar. 2007).

This brought again a topic to my attention that we have focused on for some time in Munich but never really completed. Mirrors with enhanced functionality, that can display information, capture what you were wearing at a certain date, or give you… Continue reading

In the resent month the question about ubiquitous, pervasive, ambient computing came up several times. An email by Jos Van Esbroeck motivated me to write my view on it…

Clarifying the terms seems an ongoing process as various communities and individuals use each of those terms for new things they are doing.

For me the best way to discriminate the terms ubiquitous computing, pervasive computing, and ambient intelligence is by their origin, history and research communities.

The first term (ubiquitous computing, ubicomp) is linked to Mark Weiser and his vision of computing in the 21st century [1]. In the research… Continue reading

Based on the submissions we have selected in a peer-review process 4 papers for presentations and discussion the the Ubilog’07 workshop. The program including title and abstract is online at http://ubilog.iai.uni-bonn.de/2007/program.html

The workshop is part of the Conference Informatik-2007 and will be held on the 27th of September in Bremen, Germany.

The visit to the eCulture Factory showed me again that bringing new media into the real public space creates new and very valuable insights, even though it is difficult and costly. Such installations can give a glimpse of what future public space will be. When thinking of the design space for media in public spaces one can image to create completely different and new experiences. Contextuality and awareness seem key design criteria.

Transforming public space using digital technology offers a lot of chances. However it seems that currently a lot of people think about this mainly with regard to new… Continue reading

It is always great to visit the pervasive computing labs in Linz – always new and cool research to see. Looking at my my Google News-Alert it seems that the term “pervasive” is dominate by Alois 🙂

Alois Ferscha showed me their interaction cube. It is a really interesting piece of research and the background and argument of the cinematic of the hand shows a deep insight. There are some slides on the Telekom Austria Cube that are worthwhile to look at. It is interesting that he has gone successfully the full cycle from concept to product (image is taken… Continue reading

In 2005 Friedeman Mattern organized a symposium at ETH Zurich on how computing impacts everyday life (http://www.comp21.inf.ethz.ch/). He edited a book (Die Informatisierung des Alltags. Leben in smarten Umgebungen, @Amazon) which includes versions of most of the talks. The book is in German.

I contributed a chapter to the book (draft version) on the symbioses between humans and computers. In the paper the idea of novel user interfaces that augment human capabilities and improve our ability in what we can do with technology is assessed. It is mainly based on the work done… Continue reading

This morning we took some time to walk along Nevsky Prospekt, crossing Anichkov Bridge all the way to the Hermitage and to the river Neva (which was nearly completely frozen). The streets were very busy with people.

… but nearly nobody spoke on the mobile phone. It does not need much brain to figure out why – after just taking a few photos with my phone I had really cold fingers and quickly put my gloves on again! Remembering a summer day last year in Rome – were nearly everyone spoke on the phone – I wondered what phone terminal… Continue reading
