Drawing on frameworks from Media Archaeology, History of Computing and History of the Sciences this project explores the relationship between Augmentative and Alternative Communication (AAC) and the history of special hard- and software for computer users with dis/abilities in the Federal Republic of Germany between 1980 and 2000. The project focuses on institutions such as the Research Institute Technology and Disability (FTB), where the development and testing of communication aids for people with dis/abilities and research on accessible information technology were inseparable. Within the course of the project, archival material will be made accessible and oral history interviews will be conducted. The relationship between AAC and computer accessibility will be addressed from three perspectives: (1) historical-epistemological reconstruction of the establishment of institutions such as the FTB with regard to their interdisciplinary context (2) media-archaeological investigation of the hard- and software developed during that time (3) analysis of the dominant styles of thoughts within AAC-research in regards to questions of inclusion, participation and diversity.
