Braille refreshable display using Arduino for visually challenged people (original) (raw)

This article presents an idea to provide visually impaired people access to any printed material or soft copies available on the computer. This project is a suitable alternative to Braille books. This initiative enables a blind person to read texts which are not available in the Braille format. An image sensor enables the user to take images of the text to be read. The dots of the script sensed by the user are elevated electromagnetically by precise actuators. Different experiments are carried out and the results analyzed for distinct cases. Analysis shows that proposed system have the benefits like accurate processing, recognition and detection. It is possible to extract text from the image. The blind can therefore read any printed work or text by clicking an image. The developed algorithm can be further improved with noise rejection techniques, for increased user convenience when interacting with the real world.
