Following the talk of Nikolai Krambrock we discussed the use context, and in particular location, to restrict or allow access to information. My favourite example is an online-banking appliance that only works in predefined areas (e.g. at home and in my car). Using context appears one option in creating human understandable solutions for secure systems. People have developed means to protect physical objects and valuable, perhaps we should draw more on this experience in the design of secure systems.
At the dinner of this yeas GI conference Professor Gerhard Krüger became the 6th honorary member of the German Computer Science Society (GI, Gesellschaft für Informatik). He was one of the people who understood very early that computer science is a central topic and pushed in the 1980ies form higher capacities in computer science at German Universities.

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.

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:

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.

Heiko presents a paper that shows that eye gestures can be used to interact with a computer. In his experiments he shows that users can learn gesture with eyes (basically moving the eyes in a certain pattern, e.g. following the outline of a dialog box). The paper is part of his PhD research on eye-tracking for interaction. More details are in:
Heiko Drewes, Albrecht Schmidt. Interacting with the Computer using Gaze Gestures. Proceedings of INTERACT 2007.
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:

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.

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.
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.

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:
Dagmar Kern, Albrecht Schmidt, Michael Pitz, Klaus Bengler. Status- und Kontextinformationen für die Telekommunikation im Auto. Mensch & Computer 2007. Weimar, September 2007.
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:

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).

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…

It looks like pixels and is abstract in comparison to the other windows (which have traditional picture motives). To me it seems a neat idea that somehow reflects our time.
