>On his way from Eindhoven to Zurich Morten Fjeld was visiting our group. It was great to catch up and talk about a number of exciting research projects and ideas. Some years ago one of my students from Munich did his final project with Morten working on haptic communication ideas, see . Last year at TEI Morten had a paper on a related project – also using actuated sliders, see .
In his presentation Morten gave an overview of the research he does and we found a joint interest in capacitive sensing. Raphael Wimmer did his final project in Munich on capacitive sensing for embedded interaction which was published in Percom 2007, see . Raphael has continued the work for more details and the open source hardware and software see http://capsense.org. Morten has a cool paper (combing a keyboard and capacitive sensing) at Interact 2009 – so check the program when it is out.
We talked about interaction and optical tracking and that reminded me that we wanted to see how useful the touchless SDK (http://www.codeplex.com/touchless) could be for final projects and exercise. Matthias Kranz had used it successfully with students in Linz in the unconventional user interfaces class.
