Braille literacy is very vital in facilitation of independent reading, education and communication among the visually impaired. Availability of affordable Braille learning and display systems is however low especially in environments with limited resources whereby commercial refreshable Braille displays are prohibitively expensive. In this paper, a low-cost assistive platform that is intended to aid in the learning of the Braille, visualization, and prototype of a system is presented. The offered system makes Grade-1 patterns of Braille represented in real-time, which lets the user comprehend the character mapping and sequencing. The design is focused on affordability, modularity and implementation ease, which fits the educational institutions and assistive technology development. The system has been proven to be reliable in converting textual input into relative Braille patterns. Even though the existing implementation offers a non-tactile representation, it is an effective training/validation tool of students, educators, and researchers. The suggested solution demonstrates the possibility of creating scalable and cost-efficient assistive solutions.
