With the advances from both mobile and pervasive computing, the ubiquitous computing is being realized. Under this computing environment, a new style of context-aware services are being considered for providing personalized services based on the user's context, which includes any information to characterize his situation. Context Toolkit[3] is context-aware framework that helps to build context-aware services more easily. In this paper, we design and apply a context-aware service, the visitor management system, using Context Toolkit. This system can manage consumer's visit information effectively by instantly informing visitors owner's current situation or informing owners situation of visits to them.
