BraillePlay: A Gamified Assistive System for Enhancing Braille Literacy in Visually Impaired Children

Abstract

This study presents BraillePlay, a gamified tactile learning system designed specifically for visually impaired children aged 6–12. Building upon a 2024 braille prototype [ 6] , this work shifts focus from functional demonstration to evaluation of learner engagement and learning experience. The system integrates a 12-pin braille display, QR code recognition via ESP32-CAM, and audio feedback to create an interactive learning environment. To enhance engagement, a game-based learning module was developed, featuring character identification challenges, sound-based quizzes, and a reward system with LED feedback. System effectiveness was evaluated using a 5- point Likert scale satisfaction questionnaire and teacher observation of learner engagement. The device was tested with 15 participants (10 children, 5 teachers) over two weeks. Results showed 100% accuracy in braille actuation and QR reading, with 97.5% audio reliability. More importantly, the average satisfaction score from the 5-point Likert scale questionnaire was 4.7/5 from children and 4.5/5 from teachers, with an average engagement level of 4.4/5 based on teacher observation. Key challenges included occasional servo jitter and delayed audio response. Proposed enhancements include 3D- printed motor housings, S.D. card integration for scalable audio, and a companion app for progress tracking. This work demonstrates that play-based interaction significantly improves braille literacy acquisition among children, paving the way for future assistive technologies that prioritize engagement and accessibility.
