Dispositivo electrónico de aprendizaje alfabético traductor de voz a braille

Abstract

This research project is based on the need for autonomous learning of braille, so an electronic learning device is implemented that translates voice into braille alphabetically. This device has been created so that people with visual disabilities can study and face life in a more independent way, with the purpose that people with visual disabilities learn the braille literacy system in an autonomous way, which will allow them to communicate more effectively with the environment in the future. This device consists of a matrix of points in which the alphabet is represented in braille form, this matrix is connected to a microcontroller which in turn is connected via the Internet to a mobile application that translates voice to text and sends the signal to the microcontroller, this is responsible for interpreting the text and translating it into the form in which braille is represented, this is achieved through an algorithm which assigns each letter a sequence of points that are then represented in the relief matrix, thus the user can go learning the braille writing system autonomously. The tests were carried out at Julius Doephner Educational Unit, in students and teachers with visual impairment, concluding that the device is of high usefulness for the learning process of the teacher and the student, because by having a device of this type, you are facilitating the learning of braille.
