User centered design applied to an app for incidental learning of languages and cultures

This paper focuses upon the piloting of UniOn!, a mobile application for the incidental learning of languages and cultures developed to support mobility students within the ILOCALAPP project (www.ilocalapp.eu). After the methodological phase (dedicated to the methodological framework and to the end-users' consultation), and with the development phase (dedicated to the production of materials and their technological implementation) approaching its end, the project teams are now about to test the prototype of the application. Nevertheless, preliminary tests have been conducted all along the project phases and their results are proving useful to structure the final pilot phase. In this paper we will outline all the issues related to the testing of the application and its crucial impact on the final release.
