Protótipo de um recurso didático eletrônico para auxílio na alfabetização em braile

Abstract

The regular literacy process with children with full visual abilities is very interactive, visual, and even fun since playfulness is a constant and present part of early childhood education. However, considering visually impaired people, whether blind or with low vision profile, this educational process, which otherwise may have virtually infinite didactic and pedagogical resources, lacks them due to their absence or limitation imposed by costs. Thus, this work proposes the construction of a didactic device accompanied by low-cost embedded electronics to assist in learning to read the braile code system. The device is composed by two rows of moving parts which can be relocated in a third row below to form any words of up to four letters. That word, in turn, will be interpreted through the electronic circuit of the device and sent via Wi-Fi to a database in common with an application developed for Android that will “read” the formed word to the student. In this way, it is possible to use this device as an aid in teaching what is the most popular reading and writing code system in the world for blind and low vision people in a didactic, modern and, mainly, autonomous way.
