摘要：This paper presents our work on a service framework for supporting pervasive computing systems. In our vision, a novel mobile service based on pervasive computing requires to provide high accessibility regardless of computing platform and user context. From that point of view, user interface is one of key issues to achieve the vision. Therefore, we discuss technical challenge such as adaptation and context-awareness in terms of user interface. In this paper, we described the requirements and design for the service framework, and its application through explaining a possible scenario. Then we identified diverse modality as a technical challenge for achieving such mobile service and applied media conversion for adapting data representation to each particular modality. Besides, we carried out user trial using an experimental prototype. The results of the trial show the proposed approach for modality adaptation is beneficial to users in some aspect through usability and feasibility analyses.
