Abstract
The pervasive computing paradigm provides the user with a uniform computing space available everywhere, any time and in the most appropriate form and modality. These aspects produce the need for user interfaces that are usable, multimodal and personalized for each user. In this paper multimodality is discussed. In particular, features and computational issues of the multimodal interaction are analyzed in order to examine methodological aspects for the definition of multimodal interaction languages for pervasive applications. The multimodality is faced at a grammar level, rather than at a dialogue management level. This means that different unimodal inputs are considered as a unique multimodal input that is sent to the dialogue parser that uses the grammar specification to interpret it, rather than to be distinctly interpreted and then combined. The main objective of the paper is thus to explore multimodal interaction for pervasive applications through the use of a multimodal language rather than through the integration of several unimodal languages.
