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:
Ubicomp 2008 will be in Korea.
Alireza Sahami presented our CardiViz project at the demo session at Ubicomp. We were very happy that the project that was the result of our IPEC course on developing mobile applications was accepted as a demo.

Jonna Häkkilä, Anind Dey, Kari Hjelt, and I organized organized the Ubiwell workshop (Interaction with Ubiquitous Wellness and Healthcare Applications) at this years pervasive. Alireza presented another paper on heartbeat monitoring there:

It is often discussed whether or not the user interface in the car matters or not. The basic argument is that cars are emotional and hence the driving experience matters and everything else is secondary.
However it seems the user interface becomes more and more part of the experience. On Saturday night I travelled via
The opening keynote at Ubicomp was given by Antonio Calvosa from Ferrari. Here two a very experienced and user interface focus could be seen. The talk touched issues of emotion and affective issues. Overall he argues that Ubicomp technologies should amplify what humans like to perceive.

Richard’s paper is on collaboration support with a proxy based approach. Using our previous work on the UsaProxy we extended the functionality to supported synchronous communication while using the Web:

Some weeks ago Ben Sutherland from The Economist called. He was researching for an article discussing the computing revolution over the last 25 years. In his research he to talked to many different people (from different countries, different fields, different views) and was particularly interested in applications that will come in the future and with me in particular on the concept of context-awareness.
The article „The trouble with computers“ appeared 6th of September and discusses a mix of ideas and viewpoints. We talked about 30 minutes on the phone and I am quite surprised what statement he picked from me (I said many things that were more interesting ;-). However I think it is great that people start trying to understanding the radical changes computers introduce – everywhere.
In the school museum I came across two very simple pen-based computing aids. The devices are very simple mechanical tools that help to do addition and subtraction. It was called ADDIATOR.
The utility is limited to addition and subtraction and it provides a very simple mechanism to deal with carry-over. If the number which is to be moved is white the calculation is without carry-over and one pulls it down. If the number is red then there will be a carry over one has to pull up and around the semi-circle (this is the mechanism for carry over). A carry over beyond the next position is displayed with a special sign and has to be resolved by moving the next position. The curator told me that he remembers people in shops used them and that people where very quick with them. It seems they have been popular till I was born.
After my daughter started school on Saturday we visited a historic school on Sunday. Comparing teaching materials is interesting. Especially providing up to date information in geography must haven quite a costly task. Many expensive charts and maps that were printed on canvas are now freely available in digital form. It seems that instead of having a film project, a slight projector, an overhead projector and canvas displays a computer and projector with internet access will do. Similarly having stamps to reproduce maps seems like ancient history, even though it has been still in use 20 years ago.
However I wonder what we loose by make things digital and whether or not this matters. Having a database (a box with cardboard dividers and a lot of paper slips) or a typewriter (with types that are moved by pressing buttons) on your desktop gives you a very immediate impression how things work. It is remarkable to see that historically tangibility of teaching materials was very common.
I think in the digital we should make more effort to provide means that people can understand the mechanism behind the technology (basics of HCI – conceptual models :-). This is however extremely difficult for purely digital products. My generation seems very lucky to have been witnesses of this transformation for many products from the physical to the digital – providing a lot of insight to us.
The last 3 days we were at the German HCI conference (Mensch und Computer) in Weimar. Overall the conference had a really interesting program (21 papers with an acceptance rate of 30%), presentations from usability professionals and a number of workshops.
Dagmar Kern presented our research on improving in-car telecommunication that was carried out together with people from BMW group in Munich. For details see:

Heiko Drewes showed the initial results of the studies on eye-gestures for interaction. In this paper we proof that it is possible and sensible to use gesture with the eyes to interact with a computer. For more see the picture:

At the German HCI conference (Mensch und Computer) I organized together with Paul Holleis and Klaus Bengler (BMW Group) a workshop on automotive user interfaces. We were surprised how many people work and research in this area in Germany and Austria.
The 9 talks showed a wide range of research results and questions ranging from activity recognition, search interfaces, cultural issues to research methods. Dagmar Kern presented our work on a new method for interviewing drivers at the gas station. Stefan Graf from BMW groups had an interesting demo on object oriented interaction and in-car text input.
In the final session we discussed on future challenges of automotive user interfaces and it seems that it is a great challenge as cars are very emotional products. One interesting point was that user interfaces may not be central for the decisions which car to buy – but if not satisfied it will influence the decisions not to buy such a car again.
Context and context-awareness (e.g. based on user activity, driving parameters and location) seems to provide a great opportunity for future interfaces and in-car applications. One nice example was presented by Susanne Boll from a joint project with VW (C3World, connected cars in a connected world).
At the moment I am travelling a lot on the train and it seems that there is an increase in people using their mobile devices (e.g. Sony PSP, mobile phones) to watch cinema movies and episodes of TV-shows. Some individually and others even share the experience. Over the last years it become popular that people watched DVDs on their notebook computer on the train – but it seems the real mobile age is moving on.
Even though the screen is very small it shows again that one needs little to create the illusion of a movie. In the end it comes always back to the story…
