SIGN-HUB aims at preserving and fostering a largely unknown part of our common heritage: the cultural and linguistic heritage of the Deaf communities. Apart from the digital platform we are creating to host the work we are developing in 4 different areas (grammars of six sign languages, an atlas of linguistic structures of the world's sign languages, assessment tools and interviews with Deaf elderly people), we aim at posting relevant information on sign languages and the Deaf community on the general and local websites.
