Text to Braille Translator Prototype

Abstract

This project presents the development of a prototype hardware system designed to improve access to printed text for those who are blind. It does this by converting standard print text into readable braille output. The primary objective of this project was to design and test a low-cost device capable of translating text images into physical braille characters using programmable hardware. The prototype was built using a Raspberry Pi microcomputer along with solenoids, relay modules, a breadboard, and a button for push activation. A python program was written to process images of printed text and translate them to their corresponding braille. Due to budget constraints, the hardware system only consists of twenty-four solenoids arranged to form four braille cells. When the button is pushed, the Python program is run to convert the sample image into binary braille. This binary output is used to control the relay modules, which in turn activate specific solenoids to raise the appropriate dots for each braille character. The final prototype produces four braille symbols that can be read by touch. It demonstrates the feasibility of converting printed text into tactile braille through relatively inexpensive materials. This project highlights the potential for further development of assistive technology that could translate printed media into braille in real time
