Bridging the Social & Technical Divide in Augmentative and Alternative Communication (AAC) Applications for Autistic Adults

Abstract

Natural Language Processing (NLP) techniques are being used more frequently to improve high-tech Augmentative and Alternative Communication (AAC), but many of these techniques are integrated without the inclusion of the users’ perspectives. Autistic adults are particularly neglected in the design of AAC tools. We conducted in-depth interviews with 12 autistic adults to find the pain points of current AAC and determine what technological advances they might find helpful. We found that in addition to technological issues, there are many societal issues as well. We found 9 different categories of themes from our interviews: input flexibility, output flexibility, selecting or adapting AAC for a good fit, when to start or swap AAC, benefits, access as an adult, stumbling blocks for continued use, social concerns, and control of communication. In this paper, we go through these categories in depth and then suggest possible guidelines for developers, NLP researchers, and policy makers.
