For the ubiquitous computing environment, an important assumption is that all the components in any specific environment are connected with each other. With this assumption, we introduce an effective scheme to provide a personalized service based on Virtual Personal World(VPW). Virtual Personal World (VPW) which is a model focused on service continuity of personal world. Previous ubiquitous frameworks have been concerned with where is the user is serviced and what services can be offered in that space. However those questions above are not the most important problems anymore in VPW. It concentrates rather whether the user wherever goes is offering successive services or not. Services are not regarded that objects in only one space constitute a service but Virtual Objects (VO) in other spaces can participate in the space. This composite services is possible that VOs have polymorphic characteristics which is proposed in this paper.
