We made scrabble board and alphabet by using acrylic sheet, and the top of the alphabet has braille stickers. We applied Image Processing to detect the character placed on the board by using Raspberry pi 4 and a Raspberry pi camera. To identify the image, we use Optical Character Recognition from Google Tesseract-OCR, engine along with Python and OpenCV.
