Um protótipo baseado em sistemas embarcados para suporte ao ensino de Libras

Abstract

In Brazil, approximately 5% (five percent) of the Brazilian population has some degree of hearing impairment, totaling around 10 (ten) million people, of whom 2.7 (two point seven) million have profound deafness. Brazilian Sign Language (LIBRAS) is recognized as the first language of the deaf community, playing a fundamental role in communication both among deaf individuals and between deaf and hearing individuals, promoting greater accessibility and inclusion. Information and Communication Technologies (ICTs) facilitate the provision of personalized educational experiences, expanding the possibilities for interaction between educators and students and, consequently, optimizing task performance with greater efficiency and intelligence. In this context, embedded systems emerge as a promising alternative for teaching LIBRAS. Given this scenario, the development of a semi-functional prototype based on embedded systems to support the teaching and learning of LIBRAS becomes relevant. The prototype was designed using the BitDogLab platform in conjunction with the Raspberry Pi Pico W board, integrated with an OLED display and an LED matrix to visually represent vowels in LIBRAS. The methodology employed in this research was mixed, with data collected through questionnaires directed at specialists, structured according to the Unified Theory of Acceptance and Use of Technology (UTAUT2) model to evaluate technology acceptance. The results reveal that the prototype was positively received, indicating its potential for teaching vowels in LIBRAS.
