Accessible communications such as public government announcements , television and radio news, emergency announcements, etc. are, in usually transmitted, for various reasons, in written or oral form.

Recognized as a reference organization for the defence of the rights of Deaf and hard of hearing people, ReQIS wants to promote communicative accessibility as a strategy for universal accessibility in order to reduce the barriers faced by deaf and hard of hearing people in the exercise of their citizenship.

It is therefore important to identify the issues surrounding communication in sign language as it is the keystone of communicative accessibility for deaf and hard of hearing people.
