I participated in the Dagstuhl seminar 'Proxemics in Human-Computer Interaction' in November 2013.
I participated in the OASIS UIML Specification Technical Committee between 2005 and 2008. The purpose of the technical committee was to develop a specification for an abstract meta-language that can provide a canonical XML representation of any user interface.
