Our innovative braille display, focused on affordability and education, fills a notable void in the market of refreshable braille displays, which are typically costly and not designed primarily for educational use. This product stands out as an economical educational aid for people with visual impairments. It features a system where pressing a keyboard alphabet key corresponds to specific braille pins, allowing for the display of letters or characters. Additionally, our design can represent simple geometric shapes, like circles or squares, using the braille pins. When these pins are raised, the user can feel the braille representation of the character or shape. To achieve the ideal balance of cost-efficiency and functionality in our refreshable braille display, we iterated the design through 3D printing. We determined the most effective version by conducting tests in local braille schools. This poster highlights our journey, displaying the evolution from our initial 3D model prototype to the current functional model of our braille display.
