Abstrakt: Purpose: This article highlights the contributions of three pillars of an evidence-based practice approach (service providers, researchers, and families/clients) in the development of a framework to offer a way forward for professionals, families, and technology companies to support optimal visual and communication outcomes of individuals with cortical visual impairment (CVI) who use augmentative and alternative communication (AAC). By providing available research findings as well as practical information and lived experiences, the article offers clinical considerations and design features that can lead to addressing the unique needs of these individuals.
Method: This article reviews literature concerning what is known about CVI and describes in detail and from multiple viewpoints important features required in AAC systems to support individuals with CVI and enable them to communicate effectively.
Results: Components necessary for teams, communication partners, and AAC designers to optimize AAC system design in CVI are presented using external research evidence as internal evidence from lived experience to support their importance.
Conclusions: An AAC system design that is tailored to the unique visual processing characteristics in CVI is likely to promote positive communication outcomes. The presentation of the lived experience of an individual who has CVI themselves illustrates the need for individualized assessments and interventions that incorporate and reflect the research presented here.
