I was invited to Leipzig to talk about social networks and in the context of insurance companies (http://www.versicherungsforen.net/social-media). The main focus of the talk was to show what people currently do in social networks and to speculate why they do it (and  I used a picture of the seven deadly sins as an illustrations…) Additionally I discussed some prototypes of activity recognition and their potential once integrated into social media.My talk was entitled “500 Freunde (auf Facebook): Wozu noch eine Versicherung?“ – „500 friends (on Facebook) – Is there still need for insurance… Continue reading

Andrew Kun invited me to give a talk at the Univeristy of New Hampshire in Durham on my way back from CHI. The talk was on “Embedding Interaction – Human Computer Interaction in the Real World”. In the afternoon I got to see interesting projects in the automotive domain as well as an application on a multi-touch table. At CHI we ran a SIG on Automotive User Interfaces [1].

Seeing the implementation of Project54 live was very exciting. I came across the project first at Pervasive 2005 in Munich [2]. This project is an interesting example of how fast research… Continue reading

Nicolas visited us in Essen to give the opening talk of our German meeting on tangible interaction. In his talk he first showed some examples of the hardware and sensors group at Microsoft research in Cambridge, most notably the SenseCam (which we learned is licensed and will be soon commercially available).

In the main part of the talk Nicolas presented a modular embedded architecture that allows developers to create custom made digital systems with fairly little effort. By integrating physical development (3D printing), functional blocks and software development the approach aims at empowering developers to create entirely new devices. His… Continue reading

Jari Ikonen from the Finnish Ubicomp program contacted me last week – interestingly because I shared on this blog the information that I will be in Tampere – and it worked out that we met.

He showed and explained me the demola approach. I find this concept of teaching, training and innovation very exciting. In short demola offers space for students to work on challenging problems that are real and creates opportunities opportunities. Basically companies offer tasks/project to works on. Teams of students (potentially from different universities and fields) will work together to solve it as part of their studies… Continue reading

This month at the Java User Group meeting some groups of the University presented their research. First I considered to talk about JAVA on mobile phones (e.g. the tutorials we do with teachers on JAVA ME or JAVA on Android) but then decided to talk more about the ubicomp vision and about how I think computing will change and is already changing the world 🙂 My talk “Ubiquitous Computing and Beyond – Mobile Communication changed the world – what else do we need?” was aimed at opening a discussion what will be the challenge after mobile computing is… Continue reading

I was invited to give a talk on “Embedded interaction with display environments” to discuss human computer interaction and technology issue for creating interactive display systems. The summer school has very diverse program! and I have enjoyed listening to my colleagues as much as presenting myself 🙂

In the talk I have a (more or less random) selection of technologies for making display environments interactive. There are the obvious vision based approaches (see the talk for the references) but I think there are many interesting approaches that are not yet fully explored. – including spatial audio… Continue reading

In the afternoon I gave a talk at NEC labs in Heidelberg on ubiquitous display networks. Over the last year we developed and number of ideas and prototypes of interactive public display systems. We run a lab class (Fallstudien) on pervasive computing technologies and advertising together with colleagues from marketing. In another class (Projektseminar) we investigated how to facilitate interaction between interactive surfaces (e.g. multi touch table) and mobile devices. One of the prototypes will be shown as poster at mobile HCI 2009 in Bonn. In some thesis projects we introduced the notion of mobile… Continue reading

When preparing my talk for the BMW research colloquium I realized once more how much potential there is in the automotive domain (if you looks from am CS perspective). My talk was on the interaction of the driver with the car and the environment and I was assessing the potential of the car as a platform for interactive applications (slides in PDF). Thinking of the car as a mobile terminal that offers transportation is quite exciting…

I showed some of our recent project in the automotive domain:

At Nokia Research Center in Tampere I gave a talk with the title “Computing Beyond Ubicomp – Mobile Communication changed the world – what else do we need?“. My main argument is that the next big thing is a device that allows us to predict the future – on a system as well as on a personal level. This is obviously very tricking as we have a free will and hence the future is not completely predictable – but extrapolating from the technologies we see now it seems not farfetched to create a device that enables predictions of… Continue reading

In Cologne in the Museum Ludwig I gave in the afternoon a talk on “Illusions 2.0 – embedded interactive media” at the Forum Mediendesign. The talk focused on the new qualities of magical experiences we will be able to create with pervasive computing technologies in the future and linked this to Alan Kay’s notion of user illusion and metaphors. I looked at trends that are ingredience for creating Illusions 2.0 – in particular ubiquitous communication and display, constant tracking and logging, and the decrease of value of traditional content (text, audio, video, software, tv, statistical data). I highlighted one… Continue reading

Lucia Terrenghi and Thomas Lang from Vodafone R&D in Munich visited our lab. We talked at lot about the future role of mobile devices and in particular how they may change personal computing in the near future. 

After lunch they gave a talk for our students describing Vodafone research and their particular research interests. Using a nice visualization of train lines they showed the research themes and introduced some of their research foci. One area of interest is electronic paper, resulting future devices and potential applications and services. In the discussion I briefly mentioned that I had a look… Continue reading

Today and yesterday I am visiting a conference that is concerned with ageing – looking at the topic from different perspective (computer science, psychology, medicine, economics) run at the MPI in Berlin. The working group is associate with the the German Academy of Sciences Leopoldina and I was invited by Prof. Ulman Lindenberger who is director at the Max Planck Insititut and works in Lifespan Psychology. The working group is called ageing in Germany (in German).

Antonio Krüger and I represented the technology perspective with example from the domain of ubiquitous computing. My talk “ubiquitous computing in adulthood and… Continue reading

In Gelsenkirchen (just 15 minutes on the train) was today a conference on accessibility “Einfach für Alle” (easy for all). http://www.einfach-fuer-alle.de/tagung/

I was invited as an expert in the workshop on business opportunities for the internet of the future and of assistive technologies. The workshop was moderated by Thomas Hänsgen and the other experts were Arthur Ortega (Yahoo!) and Günther Weber (Vodafone). The discussion was very lively and I learned a lot! Some results of the discussion are online at the workshop website.

To start with everyone had the opportunity to give some statements – I had the following: (1)… Continue reading

People take mobile devices into their cars and the amount of information people have on those devices is huge – just consider the number of songs on an MP3-Player, the address database in a navigation system and eventually the mobile web. In our work we looked at ways to design and implement search interfaces that are usable while driving [1]. For the paper we compared a categorized search and a free search. The was another paper in the session looking at practice of GPS use by Leshed et al. which was really interesting and can inform future navigation or context-aware… 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

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

Paul Holleis presented at TEI’08 the results of the research he did during his internship at Nokia Research [1]. Over the summer Paul spent 3 month with Jonna Häkkila’s group in Helsinki, where he worked on two projects: combing touch and key-presses and wearable controls.

Technically both projects used capacitative sensing to recognize touch. In his paper “Studying Applications for Touch-Enabled Mobile Phone Keypads” [1] they added to common mobile phone buttons touch sensing so that multiple levels of interaction can be measured, such as approaching, touching and pressing. The paper additionally discusses new interaction possibility that arise… 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

I was today in Karlsruhe at Learntec, a trade fare and congress for technologies in learning, training and education. Alois Ferscha organized a session on pervasive computing and learning.

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

In Frankfurt there was today an expert meeting on RFID and ubicomp organized by the Fraunhofer ISI. The purpose was a discussion about the impact of RFID technologies. The organizers will use our input to inform the creation of a document of technology assessment for the German parliament. The majority of the participants came from companies developing RFID technology or system.In the first part of my talk “RFID and Beyond” I highlighted results from two workshops where I was a co-organizer: PTA2006 and Pertec2007 held at the Pervasive and Percom conferences. The results were also published in 2 papers… 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.

Prof. Jürgen Ziegler, a colleague at the University of Duisburg-Essen… Continue reading

Yesterday we visited the computer science department at the University of Hamburg. Prof. Oberquelle und Beckhaus had invited me at the Mensch & Computer conference to visit them and give a talk about our work.

Before the seminar we had a chance to see the lab of Steffi Beckhaus. I have tried the ChairIO – and it was fun. They sound floor creates a really interesting experience (similar to the butt-kicker just more intense). We could also play with GranulatSynthese and try the smell user interface (apple smell is absolutely convincing, not sure about some of the others).

We… Continue reading

Sven Behnke, who won with his humanoid robots the RoboCup, visited us today at Fraunhofer IAIS. In his talk he presented the RoboCup vision – wining in 2050 with humanoid robots against the human world champions and his work towards this goal. There are interesting videos of the robots at http://www.nimbro.net

When I saw Sven presenting the first time (in 2003 at the DFG final round for the “Aktionsplan Informatik”) I was convinced that humanoid robots are far in the future and that the robocup vision is more wishful thinking than vision. Seeing how much it advanced over the… Continue reading

Yesterday we had the opportunity to see a set of research demos at the lab of Antonio Krüger at the University of Münster. We had some time to discuss research projects and in the afternoon Nigel and I gave a talk at the Geoinformatics seminar.

We saw exciting work in progress – a nearly ready large scale multi-touch display based on frustrated total internal reflection – according to Antonio the world-largest at the moment. The principle of operation of such a display is very appealing and the demo was convincing. For a comprehensive introduction on the topic see Jef Han’s… Continue reading

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… 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
