A study on the architecture and voice dialog scheme for a personal Web service in a ubiquitous communication environment

The expansion of the Internet and the development of a ubiquitous society are expected to bring about the convergence of ubiquitous networking technology and Web technology, which in turn will provide opportunities for the creation of entirely new services. In this paper, we propose a Web service tuned to individual users by integrating Internet home appliances (specifically weight scales) and Web service technology, and we discuss how it should be constructed. We further propose a system that holds VXML-written scenarios as metadata of Web pages, which enables Web page browsing to be controlled using voice dialog. We have built a prototype of the personal Web service including the use of Internet home appliances, and confirmed the system's feasibility. For the voice dialog, we have created VXML-defined metadata and carried out a desktop verification of the correspondence between Web page information and the associated dialog scenario.
