Desenvolvimento de um display braille de baixo custo

Abstract

Currently, for most visually impaired people, Braille displays are expensive devices. A proposal to expand access to this assistive technology, would allow the social inclusion of blind people with low purchasing power, which would be possible with a device capable of combining efficiency, portability and facilities for large-scale manufacturing. To meet these requirements, two phases of a project methodology were applied, starting from the project specifications until obtaining the concept. Soon after, experiments were carried out with the help of the visually impaired, enabling the assembly of a prototype, meeting the concept and design requirements, to evaluate the effectiveness. The challenges encountered during the experimental process led to an innovative result, because a more objective form of communication in Braille was created through informatics, applying known elements, but from another point of view. This project is viable because it allows large-scale production, using commercially available components and minimizing the cost of manufacturing an alternative device, whose prototype has had its effectiveness validated.
