Sena: ferramenta de auxílio pedagógico para aprendizagem do Sistema Braille

Abstract

This paper presents a device entitled sena, as a tool for teaching the Braille system. The objective is to help in the literacy process of children with visual impairment. For such, an exploratory research on literacy using the braille system was carried out, as well as a description of the product construction process and an interview with braille teachers. The device consists of obstacle sensors, the Arduino Mega 2560 board, the DF Player Mini module, RFID Reader RC522, RFID Tags, and a linear guide. The sena device is divided into two modules, the Electronic Braille Cell module and braille scanner module, providing 8 functions for developing necessary notions and skills for braille literacy.
