According to a statistic of World Health Organization (WHO) in 2017, there are 253 million blind and visually- impaired people in the world who need to read and learn using Braille. Braille is a system of touch reading and writing for blind persons which uses raised dots to represent the letters of the alphabet. The blind person can read the raised dots by moving his/her hand from left to right along each line. Usually, both hands are involved in the reading process in which the blind or visual impaired person uses the index fingers. Most of the time, blind people face many difficulties in their lives, especially when it comes to learning and reading. One of these difficulties is the specially manufactured devices to assist blind people, like Braille translator. These devices convert e-books to braille. However, they have some problems such as; the need of electronic version of the books, their large size, the exaggerated prices of the devices and, most importantly, not supporting the Arabic language.
Due to the scarcity in braille printed books, there is always a need for volunteers and interpreters to create softcopies from the books using Microsoft Word software in order to be translated into braille using special printers.Another complication that many blind and visually impaired learners face is the difficulty in gaining admission to the educational field. Even when they are granted admission, there is a limitation on the number of visually impaired student acceptance in King Abdul-Aziz University (KAU). According to the Head of Special Needs Unit at KAU, there are around 50 blind students who has enrolled this academic year (1440H). Therefore, by developing the right technology, researchers could help the visually impaired and blind students by providing them with many services, education-wise, that could increase the number of student admission in the scientific colleges. Also, they could give these learners the ability to read any material they need.
The project aims to enable any blind or visually impaired individual to read any text without others’ help. It reduces the time and effort used in translating into braille and has the ability to recognize any text and produce an audio version of it. The Vision of Dots (VOD) solution contains two parts; a hardware and a software. The hardware consists of Mega Arduino device connected to an engine (Servo) which is tied to long sticks. The head of these sticks represent braille dots. The software is a mobile application developed by android studio that helps the student to take a picture using the camera. The Optical Character Recognition (OCR) is used to extract the text from the picture. After that, the student can choose between hearing the text (Arabic google speech) or reading it by the braille dots device which has been mentioned in hardware part. The hardware and the software connect with each other using Bluetooth.
The project deliverables will consist of three elements; a poster or research paper, a mobile application contains Arabic OCR and controls a Mega Arduino that translates Braille language in real-time and speech translation to Arabic. The OCR has been tested by four programmers on different sizes, fonts, backgrounds, image sources and which OCR mode is used to translate (online, offline).
