In the context of inclusive education and assistive technology, this study focused on the
development of a computational tool for creating Unified Modeling Language (UML)
Use Case diagrams with accessibility features in Brazilian Sign Language (Libras),
called UMLibras. The tool aims to support teachers and students, with or without
hearing impairments, in the teaching and learning of modeling computer systems from
diagrams. The RAD (Rapid Application Development) model was adopted for the
development of the tool. RAD is an approach that is particularly suitable for individual
projects that require agile development and fast results, while maintaining the quality of
the final product. Using the JavaScript library mxGraph and the VLibras API,
UMLibras was designed to assist in the modeling of the Use Case diagram with
associated figures and videos with interpreters. It is expected that UMLibras will
contribute significantly to the teaching and learning of such UML models, seeking to
offer support to the teacher in teaching, as well as to create favorable conditions for the
learning of these students. In this sense, the use of UMLibras in educational institutions
can promote both education and the increase in job offers in an inclusive and egalitarian
manner.
