In the last years a great amount of collaborative applications have been developed. Advances in wireless technology and its integration on mobile devices offer support to user-to-user interaction on the move, becoming any place a potential collaborative scenario. With the aim of obtaining an appropiate support for the development of multi-plataform groupware applications we propose use a model-based approach for the development of interactive groupware applications (CIAM). This approach can be used for supporting the evolution of existing systems based on desktop metaphor towards mobile support. In this paper we show the application of this method to a case study, the teaching of Domotics. We will take as a starting point a collaborative e-learning environment called “Domosim-TPC”.
