This research presents the elicitation of requirements to promote the communication and social inclusion of children with intellectual disability through the evolution of an augmentative and alternative communication system. Themethodology is based on the Agile Unified Process software engineering process and the HCI process of user-centered design. The results obtained include the usability tests of the tool, the elicitation of the requirements and the non-functional prototypes of the evolution of the tool. The research contributions consist of the definition of requirements through literary bases, interviews, usability tests, and the construction of non-functional prototypes of the evolution of the system.
