Abstract

In this paper we present an innovative approach for exploiting the handheld device hardware increasing power. These results have been achieved in the framework of a larger project aimed to the definition of a platform to build mobile multimodal applications. Such project, called CHAT, has been co-funded by Italian Ministry of Research. Focusing our attention on the system client side, we will show how it is possible to use a thin client approach for building high modular client interfaces, managing asynchronous interactions originated on the server-side, eventually pushing contents using different criteria (e.g. change of the environmental context). We have studied how to build mobile multimodal clients, adopting an innovative approach based on the aggregation of what we have called "multimodal objects" that are able to exploit the benefits of both telecommunication and web protocols to manage input/output processes. Furthermore, we will report some restrictions and constraints coming from the adoption of two different environments: .NET and J2ME. We will highlight our solid experiences in this area and some prelimi-nary results of our research.
