The multimodal Hello World application is generated automatically using a Model Driven Ingeneering approach. It illustrates the input and output multimodal interactions that our approach generates. In the first activity "Hello World" the user can write "F" to get the second activity "French" and get the translation of Hello World in French, and similarly she/he can write "A" to get the translation. From the third activity the user can return to the first one using a complementarity between long touch on the text and shaking the phone (the application vibrate when the complementarity is properly applied). Finally, in the second activity the user can apply a long touch on the text to listen to a Text To Speech synthesis.
