Abstract—Though the Traditional method of teaching Braille script for the blind is simple, yet it has some potential drawbacks. Handling the marbles and the slate for a first-time does make learning very difficult. In most cases, the teacher will also be blind, so for each representation, the teacher must reach each student’s slate and change the arrangement of the marbles. This is a harder and time taking job. This project focuses on the design and development of an embedded system based electronic assistive device which eases the problem of teaching visually challenged beginner. This Project is implemented using an ordinary Braille slate with IR sensors and Raspberry Pi 2 Model B board which is cost-effective and simple. The Software is implemented in Simulink of MATLAB R2020. The placing of the marbles in the slate is sensed by the IR Proximity sensor. If the combination of the marbles placed is correct, then the Raspberry Pi’s Text to speak converter produces the audio sound output of the corresponding letter. This method provides an easy way of teaching Braille Script with less effort for the teacher.
