Towards a minimalist multimodal dialogue framework using recursive MVC pattern

ABSTRACT

This paper presents a formal framework for multimodal dialogue systems by applying a set of complexity reduction patterns. The minimalist approach described in this paper combines recursive application of Model-View-Controller (MVC) design patterns with layering and interpretation. It leads to a modular, concise, flexible and dynamic framework building upon a few core constructs. This framework could expedite the development of complex multimodal dialogue systems with sound software development practices and techniques. A XML based prototype multimodal dialogue system that embodies this framework is developed and studied. Experimental results indicate that the proposed framework is effective and well suited for multimodal interaction in complex business transactions.
