Abstract: Service provider and the user interface in ubiquitous computing adaptive problem is an important research topic. Embedded systems provide services to ubictuitous computing service played an important supporting role; pervasive computing tasks to the service users also need access to adaptive user interface to display services, embedded system, adaptive interface is appropriate choice. However, the traditional services of embedded systems software can not achieve the above goals very well. Traditional service model for embedded system deficiencies, this paper summarized the embedded systems for ubiquitous computing hardware, and named the computing-unit of this structure. Subsequently,this paper proposed a new service delivery model for embedded systems, unified user interaction context of the standard message format, and finally studied the implementation of the service model.
