Abstract. In this paper we present a demonstration of the Migrantes environment for supporting user interface migration through different devices, including mobile ones and digital TV. The goal of the system is to furnish user interfaces that are able to migrate across different devices, in such a way as to support task continuity for the mobile user. This is obtained through a number of transformations that exploit logical descriptions of the user interfaces to be handled. The migration environment supports the automatic discovery of client devices and its architecture is based on the composition of a number of software services required to perform a migration request.
