Augmentative and Alternative Communication (AAC) techniques are employed to mediate communication with people who\nhave communication disorders, as in cases of intellectual disability. Although there are various digital solutions that promote\nalternative communication options for individuals with communication disorders, only a few of them have been specifically\ndesigned or targeted to people with intellectual disability (ID). This work is motivated by the lack of AAC solutions contributing to\nthe rehabilitation processes of individuals with intellectual disability in Brazil. The study presents a mobile-based AAC solution\nconceived as a tool to assist the rehabilitation process of people with ID. The design was based on user-centered design principles\nand accessibility standards. The System Usability Scale (SUS) questionnaire was used to evaluate the solution. Four specialists and\ntwenty-five students participated in this study. The proposed solution shows the potential educational value for professionals who\nassist individuals with intellectual disability in Brazil.
