A dialog based user-interface for different devices and modalities

Today computers are moving from the desktop into our everyday life and becoming more and more ubiquitous. The challenge is to build more suitable interfaces for different devices and modalities. In this field common WIMP oriented GUIs are not the end of the development. Interfaces can be enhanced with dialog-centric approaches. In this paper we describe a dialog-based user interface management system. The system is based on an abstract dialog description language which specifies the interaction between computer and user. The dialog language is processed by an interpreter module and presented by different dialog render modules. The available render modules support common graphic user interaction, the interaction with a virtual character front end and the web-form-based interaction with a browser.
