Over the last days there were a number of interesting papers presented and so it is not easy to pick a selection… Here is my random paper selection from Ubicomp 2008 that link to our work (the conference papers link into the ubicomp 2008 proceedings in the ACM DL, our references are below):
Don Patterson presented a survey on using IM. One of the finding surprised me: people seem to ignore “busy” settings. In some work we did in 2000 on mobile availability and sharing context users indicated that they would respect this or at least explain when interrupt someone who is busy [1,2] – perhaps it is a cultural difference or people have changed. It may be interesting to run a similar study in Germany.
Woodman and Harle from Cambridge presented a pedestrian localization system for large indoor environments
. Using a XSens
device they combine dead reckoning with knowledge gained from a 2.5D map. In the experiment they seem to get similar results as with a active bat system – by only putting the device on the user (which is for large buildings much cheaper than putting up infrastructure).
presented work where he explored the use EOG goggles for context awareness and interaction
. The EOG approach is complementary to video based systems. The use of gesturest for context-awarenes follows a similar idea as our work on eye gestures . We had an interesting discussion about further ideas and perhaps there is chance in the future to directly compare the approaches and work together.
University of Salzburg presented initial work on an augmented shopping system
that builds on the idea of implicit interaction . In the note they report a study where they used 2 cameras to observe a shopping area and they calculated the “busy spots” in the area. Additional they used sales data to get best selling products. Everything was displayed on a public screen; and an interesting result was that it seems people where not really interesting in other shoppers behavior… (in contrast to what we observe in e-commerce systems).
