Umlibras web: ferramenta computacional para criação de diagramas de sequência com acessibilidade em libras

Abstract

Inserted in the context of inclusive education and assistive technology, this work developed a computational tool for creating sequence diagrams of the Unified Modeling Language (UML), with accessibility resources in Libras, which will subsidize the teaching-learning of students, with or without disabilities hearing, in the modeling of computational systems. The professor will have a didactic-pedagogical resource to help him in exposing the content related to the sequence diagram, favoring the learning of students with hearing impairment and thus promoting inclusive education. Currently, there is a great shortage of tools suitable for the context and needs of students with hearing impairments. From this perspective, the developed tool seeks to support the teacher in the proposed activities, creating conditions for the learning of these students. Named UMLibras, the tool was built using the mxGraph JavaScript library and the VLibras Application Programming Interface (API) as a base structure, aiming to assist in modeling the sequence diagram through the use of videos, illustrations and the Libras language. In this way, it is expected to contribute to the teaching-learning of students with or without hearing impairment, making their access to information and proposed knowledge easier.
