Modeling of interaction design by end users through discourse modeling

End users of software typically have to let someone else develop it and its user interface, or to learn to design and to program it themselves. Especially user interfaces developed by someone else may not fit well the given task. Designing and programming is hard and takes a lot of effort in general, and even more so for people not especially trained or experienced. Therefore, we propose end-user development of user interfaces through a new approach and interface for discourse modeling. End users may themselves model an interaction design as a discourse (in the sense of a dialogue between human and computer). From such an interaction design, eventually a user interface is to be generated automatically by a tool. As a consequence, end-user development becomes end-user modeling instead of programming.
