Design Characteristics of Augmentative and Alternative Communication Interfaces for Children With Cortical Visual Impairment: Results From Two Focus Groups With Vision Professionals.

Purpose: The purpose of the current study was to gain insight on augmentative and alternative communication (AAC) interface designs for children with cortical visual impairment (CVI). Children with CVI frequently require AAC and specific interface supports, and customization may be necessary to support access and use of speech-generating devices. Method: A focus group methodology was selected to gain feedback from vision professionals on helpful AAC features for children with CVI. Participants included eight teachers of the visually impaired and one optometrist. Two virtual 1-hr focus group sessions were conducted and recorded for thematic analysis. Results: Three primary themes and eight subthemes emerged from the transcripts of the focus groups. Themes included characteristics of the AAC interfaces such as background, high contrast, and symbolic representation; characteristics of children with CVI (preferred colors, visual field preference); and the development of AAC interfaces over time. Conclusions: Vision professionals have identified characteristics of AAC interfaces that should be considered when working with children with CVI. Future collaboration with such professionals is needed to further inform the design of current and future AAC technologies to allow speech-language pathologists to meet the unique needs of this population.
