Book Reader for Blind People using LabVIEW

Reading plays crucial role in our daily life. But blind people cannot read due to their disability. They depend braille script for reading. Speech signal is more effective means of communication than text because even blind and visually impaired persons can respond to sounds. The visually impaired can understand text if it is converted into a speech signal. This project depicts an idea to design and book reader using LabVIEW software. The Optical Character Recognition system (OCR) is implemented using LabVIEW. OCR usually reads text from paper and translating the images in to a form that the computer can manipulate. At the outset, the OCR should be trained by giving unique character for each letter of a language (Pattern). Hence the OCR can recognize all the trained letters or pattern. The letters from the text book is acquired by the mobile phone camera and it is fed in to OCR wirelessly through droid cam wireless webcam. Then the OCR matches the input pattern (letter) with trained pattern and produces the string output (i.e.,unique character) accordingly. The string output is then processed for producing audio output. Here audio files for all the letters are already defined.
