The Auto-UI 2009 conference in Essen is over - and for us it was very enjoyable to have this many visitors at the University of Duisburg-Essen - see the photos. The conference facilitated good discussions and had a very constructive atmosphere. We should continue this exchange of ideas and there is always room for improvement... and that is why there is a Auto-UI conference 2010 in Pittsburgh, US - and there is interest beyond this in hosting the conference.
You can register to get information about the next conference on the Auto-UI webpage.
The proceedings are now online in the ACM DL and the linked on the program website.
