For the second time we organized an international doctoral colloquium on HCI – mainly with students from Germany and Finland. This year it was hosted at the University of Tampere. 10 students in different stages of their PhD presented their work and ideas. The first one was in Oulu.

Besides many scientific and technological topics we discussed the process of doing a PhD. I shared my experience of doing a PhD based on an extened version of Jakob Badram’s fish model as well as with the PI-presentation model.

The fish: basically you start with a topic and it widens… Continue reading

Creativity is a key issue of creating novel applications and interaction methods and techniques. Over two days we ran a hands on prototyping workshop on physical user interaction. We setup teams of 3 people, each team including at least one person with design and one with programming skills. Within about 5 hours the teams had to create a multiplayer interactive game – using a mouse or several mice as basic sensors. We discussed how novelty and the learning curve of interaction technologies relate to physical interaction. The results of the workshop were most impressive… and I think some of them… 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

Social software and media is getting hugely popular and there are many longer explanations in CSCW and CHI why this works and what are the basic drivers. I saw a t-shirt that explains it in a single picture

It may over generalize but there is some truth in it – and given the recent figures on the prevalence of ADHA it seems to be a driving business in the future…

In my digital systems design class we have used the eZ430-F2013 development kits – they are cheap (about 20 €) and most students get it working

I have seen TI has a new development kit which is really interesting: “eZ430-Chronos Wireless Watch Development Tool” – Could be an useful basis for wearable computing projects – perhaps we should get them for the class on pervasive computing next term?

The TI commercial is on youtube:http://www.youtube.com/watch?v=LDJIBydJvoM

Some years back IBM had a Linux watch as research platform. Gábor Blaskó published some concepts and protoytpes on how to interact with… Continue reading

I am very much in favor of teaching children more than one number system (e.g. binary additional to the decimal system). To me this gives children a better understanding of the nature of numbers – I know that this seems not to be widely shared 😉

Now I found a further reason why it essential to know binary codes – How else would you decode this best before date on this chocolate bar if you would not know it!

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 becoming… Continue reading

The current issue interactions (http://interactions.acm.org) features some interesting articles – at least scanning through it and reading some of them prolonged my breakfast today considerably 😉

The cover story gives an already in its title a very interesting definition of tangible interaction (Tangible Interaction = Form + Computing) [1]. Their view is very much from a design perspective, but provides a good introduction to the topic.

The article by Jay Chaeyong Yi on a success story from Korea is a very good case study of how to apply UI research [2]. It shows (1) a comprehensive example of… Continue reading

Given the technologies around us I sometimes wonder how close we are to a vision of ubiquitous computing. In this month IEEE Computer Invisible Computing column I had the pleasure to ask this question and share my view on it.

The short answer is: many technologies are ubiquitous but there is a lot more to come. In particular we see that many technologies (public displays, people centric sensing, and personal memory devices) are just around the corner and that they may have a large impact on how we perceive computing. For the long answer have a look at my article:… Continue reading

Having a professional interest in advertising I really liked the link my colleague Bruno Müller-Clostermann sent to me. I obviously had to try it with my picture

My hero movie: http://en.tackfilm.se/?id=1265980862962RA40The example of the personalized video shows that it is intriguing and that it is potentially viral – but I am not sure if it is effective (or did you get what the advert is for?).

In general the concept to make someone a part of an advert is very powerful. At Mensch&Computer 2008 we published a paper that explores this idea in the context of public displays [1].… Continue reading

After several tries we finally managed to travel to Dortmund (half an hour on the S-Train) to visit Gernot A. Fink‘s group at the Technical University Dortmund. Bastian Pfleging did with this group his master thesis before he joined us. The research focus of the group is on signal processing and computer vision. They also follow an experimental approach – building systems that work (which we saw in the demos). In their lab space they have setup a building (basically a house inside a house – impressive!).

I have learned about a new location technology based on passive infrared… Continue reading

At the moment there is an interesting discussion in Germany: should the state buy data (leaked out of a Swiss bank) that give details on people who have not paid their taxes in Germany. I will not add to the political discussion on that as there have been many arguments – some interesting and others funny. I am only amused about a small party that is very much against it. But one has to be fair – this is after all an indicator that democracy works 😉 parties represent the interests of their voters…

I think on a more general… Continue reading

We have a number of student projects that look at novel applications and novel application platforms on mobile phones. As Michael Rohs from T-Labs is also teaching a course on mobile HCI we thought it would be a good opportunity to meet and discuss some application ideas.

I gave a talk in Michael’s lecture discussing the concept of user interfaces beyond the desktop, context as enabling technology, and future applications in mobile, wearable and ubiquitous computing. We had an interesting discussion – and in the end it always comes down to privacy and impact on society. I see this… Continue reading
