Essen - European Capital of Culture 2010

This year RUHR.2010 - Essen and the Ruhr area - is European Capital of Culture. If you ever dreamed of visiting Essen - this is the year!

Ageing, Technology, Products, Services

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 old age" is a literature review in pictures of selected ubicomp systems targeted as an introduction to non-CS people to the domain. The discussions were really inspiring. In one talk Prof. Jim-Chern Chiou from National Chiao Tung Univeristy in Taiwan (the brain research lab) presented interesting dry electrodes that can be used for EEG – but also for other applications where one need electrodes.

Antonio reported an interesting experiment on the navigation/walking performance of people. The basic message is: if you are old and you can hold on to something while walking you gain cognitive resource – if you are young this effect is not given – has quite interesting impliciations [1]. Antonio worked on more in this domain, see [2].

Over lunch we discussed some ideas related to persuasive technologies and Ulman Lindenberg hinted me some relevant authors (Bargh, Gollwitzer) and I found an interesting manual on subliminal prime on the web.

Meeting on Human Centered in Vienna

Ina Wagner, Volker Wulf and Kjeld Schmidt organized a meeting to get together people from all over Europe that work on human centred computing. We had interesting discussions what is specific and distinct European human centred computing and how well it is represented in organizations such as the ACM.

Some years ago there has been significant support in this area of research on a European level - namely I3 and the disappearing computer initiative. Currently many of us feel that the value of user centred research is not supported enough and hence innovation happens somewhere else which can lead to massive disadvantages for European industries. One central issue is that we need more to communicate value of user interface research.

The need for user interface research is undoubtedly accepted. One example is the ISTAG report of 2001 that tried to look into 2010 - a future that is now not too far anymore. Looking at the challenges stated in this report it becomes clear that most of the technical issues are solved but this does has not lead to a breakthrough with regard to the visionary scenarios. But towards the challenge "natural interfaces" we have still a long way to go. If we really want to get closer to those scenarios of ambient intelligence that are human friendly we really have to push on interaction and user interfaces - hopefully decision makers on a European level will get it ;-)

Dagmar Kern presented two WIP at CHI

Dagmar presented two work in progress papers at the poster session at CHI. One paper is a master thesis of Hema [1] and assess how we can personalize environments with coding preference into the Bluetooth friendly name. Here we were particularly interested into the acceptance in Germany and India. The second paper [2] was joint work with Nigel’s group from Lancaster. Here we look at targeted poster advertising and how preference information should be stored.
