Abstract

Braille is a standard code for people with visual disabilities that consists of an array of high points. This paper explains the implementation of a low-cost prototype for reading, writing, and audio-Assisted evaluation. This didactic and user-friendly system aims to improve the learning of disabled people by providing teachers new and modern alternatives to lead and monitor the student's activities. For designing the prototype, the researchers followed the suggestions provided by teachers of the 'Mariana de Jesus' institute for blind and deaf children. The Braille Grade 1 system consists of the following four stages: (a) writing, by the use of 10 buttons placed in matrix form, (b) reading, through 10 push-pull solenoids, (c) memorization, and (d) evaluation by using a touch display where the generated letters are displayed and assisted by audio messages. The implementation was carried out using a Raspberry Pi 3B board due to its high performance and low cost. The device improves and eases learning of Braille grade 1, allowing the monitoring of the progress reached, with and an acceptance of 91% obtained from the teachers of the institute.
