Using a mix of wireless telecommunication, digital audiovisuals and the Internet, the digital entertainments have evolved to a new form of interaction based on mobile ubiquitous computing and mixed reality. Our work is devoted to the application using both reality and virtuality in a complex mixed mode. Our research goal is to highlight constructive schemes (interfaces, narrative structure…) which can be used in the design of interactive media production. This paper is devoted to the analysis and the classification of the possible relationship between virtual worlds (VW) and real worlds (RW). It focuses on the general public, in particular entertainment applications. We discuss a general model of the RW/VW interactions and present a classification of applications. Some significant examples are discussed as a conclusion.
