Optical Character Recognition (OCR) technology allows people with a vision impairment to scan printed text and receive a synthetic speech output or save it to a computer. Currently, OCR technology cannot convert handwriting to voice output.
Optical Character Recognition (OCR) has three factors: scanning, recognition, and reading text. First a camera scans the printed document. Next, OCR software converts the image into recognizable characters/words. Then the user can store the information in electronic form to a computer or the OCR system itself.
