Assistive Device for Blind based on IoT

This is the automatic document reader for visually impaired people, developed on Raspberry Pi. It uses the Optical character recognition (OCR) technology for the identification of the printed characters using computer programming. It converts images of printed text into machine encoded text. In this research these images are converted into the audio output (Speech) through the use of OCR and Text-to-speech synthesis. The conversion of printed document into text files is done using Raspberry Pi which again uses Tesseract library and Python programming. The text files are processed by OpenCV library & python programming language and audio output is achieved.
