The appropriateness of the methods used for the target group and their participation is our main concern. Therefore we will use modern methods of AAC (Augmentative and Alternative Communication) during the events to really involve people and to gather their opinions and information about their needs together with the opinions of non-disabled persons who are concerned with the issue. 

Argumentative and alternative communication (AAC) is an umbrella term that encompasses the communication methods used to supplement or replace speech or the written word for those with impairments in the production or comprehension of spoken or written language.
