Providing multimodal context-sensitive services to mobile users

By Carmelo Ardito, Thomas Pederson, Maria Francesca Costabile and Rosa Lanzilotti


Abstract. In this paper, we describe a framework designed to provide multimodal context-sensitive services to mobile users. This work is part of the CHAT project, which aims at developing a general-purpose infrastructure for multimodal situationadaptive user assistance. We specifically describe two conceptual corner stones of the project: a) a multimodal interaction framework targeted at providing service access through different modalities for different real-world situations and for improving interaction with mobile devices in general, b) an “egocentric interaction” model for framing interaction with objects in the vicinity of a mobile user, including also other real-world and/or computational entities than the mobile device itself, ranging from computationally “stupid ” everyday objects to more advanced interactive devices such as desktop PCs. The final section of the paper is devoted to open issues in the design of the CHAT infrastructure related to the topic of user assistance in intelligent environments
