According to World Health Organization (WHO), there are approximately 2.2 billion people who are visually impaired in the world (Oct, 2019). Braille is a tactile writing system used by people who are visually impaired and is typically written on embossed paper. Reading is the most important form of learning. According to Varao Sousa [11], reading reduces mind wandering and increases understanding. For visually impaired people, reading refers to braille reading through touch. In this digital age, where everything is done online, the visually impaired have a hard time trying to access digital content or read electronic documents. Digital braille or electronic braille is a way in which the visually impaired can access information using electronic braille displays where the digital content on screen is converted into braille and is made available for use. Many electronic braille systems are printed onto paper and this form of braille is susceptible to wear and tear. Most electronic braille systems used are very expensive especially in developing countries such as India. Hence, we are proposing a digital braille system that is affordable and easy to use. The digital braille system designed converts digital text from documents to braille using python script. The system is driven by electromagnetic push-pull solenoids connected to an Arduino Uno board. The vertical movements of the solenoids represent the braille characters. Each character is read and the corresponding dots representing the character in the braille alphabet is displayed. The system can also be a handy tool for teaching and training the visually impaired people.
