Reciprocal Innovation to Optimize Low-Tech Augmentative and Alternative Communication (AAC) for Individuals With Complex Communication Needs and Their Caregivers

Many people with autism and related developmental conditions have difficulty speaking or do not use speech at all. These individuals often benefit from augmentative and alternative communication (AAC), which includes tools such as picture boards, communication books, object symbols, and structured communication routines. AAC helps people express needs, make choices, and engage socially.

In low-resource countries and underserved rural areas of the United States, high-tech AAC devices are often not available. These systems can be expensive, require reliable electricity or internet access, and depend on trained specialists who may not be available locally. As a result, families and providers frequently rely on low-tech AAC options, which are more affordable and practical in these settings.

However, low-tech AAC is often not used effectively. Common barriers include stigma around disability, limited awareness of AAC, lack of access to appropriate materials, and poor matching between the communication system, the individual's abilities, and their everyday communication environment. Inconsistent assessment practices and limited training for caregivers, teachers, and other communication partners further reduce successful use. These challenges often lead to AAC being abandoned, leaving individuals socially isolated and unable to communicate effectively.

Rural Virginia and western Kenya face many of the same challenges. In both locations, access to AAC specialists is limited, individualized assessments are inconsistent, and communication partners often receive little or no formal training. Addressing these gaps requires approaches that are scalable, affordable, and culturally responsive. Effective solutions must systematically assess individual abilities and environments, guide selection of appropriate low-tech AAC systems, and support communication partners in using these systems consistently and correctly.

This project uses a reciprocal innovation approach, in which both regions contribute expertise. Western Kenya offers experience in implementing low-tech communication systems in communities that are new to AAC, while rural Virginia contributes experience with individualized assessment, provider training, and scalable technology-based tools. By combining strengths from both settings, the project aims to create solutions that work across diverse contexts.
