Validación de un dispositivo para apoyar el aprendizaje y la enseñanza del sistema Braille

A third of the world's population suffers from visual impairment, this figure is approximately 2,200 million people without taking into account that there are individuals who have not been diagnosed due to various reasons that include lack of access to health or who are in territories outside the scope of the census system of each country. Currently in Colombia the number of people with visual disabilities rises to 551,764 people, which has implications in different social aspects. One of the biggest challenges facing the country is the literacy of this community, taking into account that to carry out this process it is necessary to use the Braille literacy system. The tools currently available in the area of ​​education for people with visual disabilities are limited, not only because of their price but also because of their low worldwide distribution, especially in Latin American countries. This can be seen reflected in the high rate of illiteracy in the population that suffers from visual impairment and therefore leads to a high rate of unemployment. This is how this project arises that aims to validate a device with auditory feedback which serves as a support tool in the learning and teaching of Braille for people with visual disabilities. For this, a methodology that is based on five stages divided into: literary review, specification of parameters, design and construction of the device, development of the virtual platform and verification of the system as a whole (software and hardware) was proposed. The results obtained were a fully functional web platform to which a device containing the generating sign of the Braille matrix is ​​connected, which when activated generates auditory feedback incorporated into the corresponding web page. The external parts of the device were obtained by means of 3D printing in a biodegradable material that does not generate pollution for the environment and is also inexpensive. A value of 99% accuracy and 100% precision was obtained, which is why it is established that the device allows the generation of all the symbols found in the alphabet of the Braille system defined for Colombian Spanish.
