Augmentative and Alternative Communication (AAC) is a term that is used to describe a range of strategies and technologies used to support people with Complex Communication Needs (CCN) or replace alternative spoken communication to promote independent learning. Studies have shown that using assistive technology in educational settings can significantly improve learning outcomes for students with disabilities (Alper & Raharinirina, 2006). These disabilities may be congenital like cerebral palsy, autism spectrum disorder, Rett syndrome, or acquired in later life like traumatic brain injury, or neurodegenerative conditions such as motor neuron disease. By using AAC, we can support people living with these disabilities. AAC supports are commonly divided into aided and unaided modalities. Unaided modalities include gestures, pointing, vocalizations, body language, eye contact, facial expressions, and sign language. Aided modalities are those communication strategies that involve external components, and may be divided into two categories: Low-Technology Aided AAC & High-Technology Aided AAC (Norrie et al, 2021)
