Multi-touch displays seen as great opportunity

In our course “case studies in pervasive computing” we re-build systems that are described in the research literature and try to improve them or to apply them to new domains. This term the topic is on multi-touch displays. Starting out with Jeff Han’s paper “Low-cost multi-touch sensing through frustrated total internal reflection” we think about novel interaction methods for large screens. And after some initial problems (filter in the web cam we used) we have a first hardware prototype that shows the FTIR effect. The page of Thomas M. Brand is a good starting point if you too think of a DIY-project.

On Monday Giulio Jacucci from the Helsinki Institute for Information Technology told me that they set up a start-up that has an new interesting and different way of doing multi-touch displays – and they look into enormous sizes of displays, up to 16 meters long. Their web page is http://www.multitouch.fi/. Perhaps we should try to get some of there technology for next term – would save us some serious drilling, soldering and polishing…
