Modeling language and CASE tool for communication board customization

Communication Board (CB) is an Assistive Technology (AT) that enables people who have speech impairment to communicate their needs or desires using visual-graphic symbols. Since each patient has individual needs, it is important to offer a customizable approach to define the vocabulary of their CB. In this context, this paper proposes a modeling language for diagramming the CB vocabulary. Its feasibility, expressiveness and usefulness were validated through the construction of a software that will be described later in this paper.
