On the 13th of November, the consortium of Content4All was welcomed at Fraunhofer in Germany. For this occasion, HFC had invited Rafael, an amiable deaf person who has been working as signer for the daily news shows of ZDF and ARD. Rafael immersed the consortium in the world of signing: from the history, to the linguistic structure of sign language. Moreover, we were able to take our first steps in signing ourselves. At the end of the day, the consortium went home inspired and with a deeper understanding of sign language.
