Abstract

Visually impaired individuals face challenges during their learning process, often due to the lack of necessary resources to acquire basic skills such as literacy and access to information tailored to their needs. Therefore, ensuring that they learn Braille early is crucial, as this will guarantee their access to knowledge and enable them to better integrate into society. Not only does it provide them with more communication channels, but it also equips them with tools to navigate the workforce. This article presents a low-cost technological solution for teaching the Braille alphabet to blind children through an electronic keyboard. The device features buttons printed using a 3D printer, each representing a letter of the alphabet in Braille, resembling domino tiles. When a button is pressed, it activates a speaker that pronounces the selected letter aloud. The electronic device is complemented by a mobile application that supports the teacher. This proposal was developed in response to a need that arose at the Centro de Atención Múltiple No. 50 (CAM) in Mazatlán, Sinaloa, Mexico, due to the enrolment of a girl (four years old) with total blindness. The school lacks sufficient resources to support the student in her learning process, prompting the development of the electronic keyboard as a teaching aid, which was donated to CAM Mazatlán No. 50.
