What it does?
Braille eye is a portable braille device for visually impaired people to read texts anywhere they travel. Our device aims to minimize the size of the Braille device and decrease the power consumption and increase the refreshing rate. The device can be divided into three main functionality, optical character recognition, Serial communication, and linear Actuation. OCR is done in Raspberry Pi with the help of an OCR engine called Tesseract. The master, RPI sends signals to the slaves, ATMEGA 328P through serial peripheral communication, which in turn actuates the micro servo motors for the raised and lowered dots.
