Game-Based Literacy for Blind People

Abstract

This prototype was designed to teach the braille alphabet to blind people using the game-based teaching approach. The software (App) connects via Bluetooth the Braille module. In the first module, the teacher trains the blind student; then in the second module, the student plays and learns. The system generates a set of letters or numbers (sequential, random or personalized), then, the system emits a sound of the letter through the speakers of the mobile device (with the Google API or with the recorded voice of the teacher), and the Braille system shows a letter. The blind student must analyze if the letter heard by the audio is the same as represented in the Braille module; if they match then he or she must mark as correct; otherwise, he or she must mark incorrect. The game has been evaluated by two teachers, the first one, teaches students with special abilities, and another one, is a psychologist dedicated to education, both mention that the game-based system would help to teach the braille system to blind people.
