Ali presented our joint work with Nokia Rearch and DoCoMo Eurolab in the paper on sharing emotions  (the acceptance rate was about 20%). The research is motivated by the question how we can make communication more emotional and how we can enable digital craft creating. The idea is to have a new communication medium were a communication item is hand crafted and can carry emotion. The questions were encouraging and we hope to continue to work on this topic.
In the poster session we had two contributions. Christian Winkler showed his project on Flash-light interaction . The idea is simple: a camera in the environment or screen tracks the flash light of the phone - but it is very effective.
Ali presented a poster on a new poker table; this is a project some of our students build last term. An interesting aspect is that the playing cards are on the phone, the table is a multitouch table, and interaction is based on gestures (on the table as well as with the phone).
Have look at the table of contents of the entire conference to get an overview of current work in mobile HCI.
