Finalizing dialog models at runtime

Abstract

This paper proposes a dialog model for web applications aiming at flexible interface generation. The basic idea is to enable the runtime system to "finalize" the dialog structure. The overall approach follows a task-oriented, user-centered development process, where models of the users' tasks and the user-system dialog play an essential role. In our approach, these models are transferred to the run time system that allows the user to interact with the web application according to the specifications. It is based on an architecture that separates a task controller and a dialog controller, which are responsible for model execution and dialog creation. Throughout the paper, we take care of the special characteristics of web applications and show enhancements of the conceptual models and of the runtime architecture. © Springer-Verlag Berlin Heidelberg 2007.
