A generic formal model for fission of modalities in output multi-modal interactive systems

Abstract

Output multi-modal human-machine interfaces combine semantically output medias and modalities in order to increase interaction machine capabilities. The aim of this paper is to present a formal model supporting formal specifications of output multi-modal interactive systems. As a consequence, the expected usability and robustness properties can be expressed and checked. This paper proposes a generic model which permits to specify the output multimodal interfaces following the CASE design space.
