I'm working on a project for a graduate course on the design of
programming languages, and, since user interface design is one of my
primary interests, I've chosen to explore the use of languages for
describing user-system interaction.  I've found references to work
using state-transition diagrams and BNF grammars, and am interested in
those and any other language-oriented approaches that have been
pursued (i.e, something other than a toolkit/subroutine library
approach).

Any pointers would be much appreciated; I would be happy to summarize
if there is interest in either newsgroup (comp.lang.misc or
comp.cog-eng). 

Thanks very much,
