Our aim is to point out the benefits that can be derived from research advances in the implementation of concepts such as ambient intelligence and ubiquitous/pervasive computing for promoting Universal Access to the Information Society, that is, for contributing to enable everybody, especially people with physical disabilities, to have easy access to all computing resources and information services that the coming worldwide Information Society will make available to the general public as well as to expert users in the near future. Following definitions of basic concepts relating to multimodal interaction, the significant contribution of multimodality to developing Universal Access is briefly discussed. Then, a short state of the art in ambient intelligence research is presented, including references to some of the major recent and current research projects in this area. The last section is devoted to bringing out the potential contribution of advances in ambient intelligence research ...
