Braille refreshable display using Arduino for visually challenged people
This article presents an idea to provide visually impaired people access to any printed material or soft copies available on the computer. This project is a suitable alternative to Braille books. This initiative enables a blind person to read texts which are not available in the Braille format. An image sensor enables the user to take images of the text to be read. The dots of the script sensed by the user are elevated electromagnetically by precise actuators. Different experiments are carried out and the results analyzed for distinct cases. Analysis shows that proposed system have the benefits like accurate processing, recognition and detection. It is possible to extract text from the image. The blind can therefore read any printed work or text by clicking an image. The developed algorithm can be further improved with noise rejection techniques, for increased user convenience when interacting with the real world.
Design of Text-to-Braille Digitized Device based on Android and Arduino Uno with Remote Module
IRJET, 2022
The objective is to utilize Arduino to make a Text to Braille Converter. The current adaptation considers Braille for the English language. There are two sorts of Braille frameworks: static and dynamic. A set plan for addressing the English 26 letters requires static braille spots of 3x2 lattice measurement. The characters are punched as dabs on paper or metal blocks. To understand reports, a static Braille system needs a large number of archives to be transmitted. This weight is reduced by using a strong braille structure. Braille is a physical system for addressing text. A Braille book is made up of a few braille cells, each of which addresses a letter in order or photograph. A single cell is made up of six distinct spots. A mixture of these pins lifted high and low frames a letter in the sequence. Many languages have a standard braille code for each letter in the alphabet. Writings are typically emblazoned on material, and visually impaired people brush their fingertips over the dabs to read the content. Because of mechanical advancements in various fields of study, Braille engineering is advancing at a rapid pace. Several languages, including English, French, and Spanish, can be written and read using Braille code. The idea is for the client's fingertips to be placed on the cell, causing cell pins to reproduce, rubbing a finger over cells.
Development of Wireless and Portable a Self Learning Braille Device Based on Android Smartphone
Proceedings of the The 1st International Conference on Computer Science and Engineering Technology Universitas Muria Kudus, 2018
Braille is an essential system for visually impairment people as a source of learning and obtaining information. The process of learning braille is still very dependent on the teacher. Our project aims at developing a self-learning braille device which can help students with visual impairment in learning the system of writing braille letters independently, without reliance on companion teachers. This system uses six small dc solenoids as linear actuators for tactile displays that are used to form a single braille display cell. The dc solenoids and other hardware components are controlled using Atmega328p microcontroller with Arduino Nano platform. To provide the wireless connection between the braille learning device and the android smartphone, we use Bluetooth technology. The solution is designed with a cheap, portable device, user friendly, and allows a blind student to learn braille independently without the help of a teacher.
IJCTA July-August 2014_Embedded_Optical_Braille_Recognition_on.pdf
Optical Braille recognition is used to digitize and reproduce texts that have been produced with noncomputerized systems, such as with Braille typewriters. Digitizing Braille texts also helps reduce storage space, as Braille texts take up much more space than their natural language counterparts. Editing and Reprinting of Braille document that were embossed on paper are time consuming and labour intensive. Optical Braille recognition is also useful for people who cannot read Braille, but need to access the content of Braille documents. This paper is on Methodology of a camera based assistive device that can be used by people to read Braille document. The framework is on implementing image capturing technique in an embedded system based on Raspberry Pi board.
Single Cell Bangla Braille Book Reader for Visually Impaired People
2018 International Conference on Bangla Speech and Language Processing (ICBSLP), 2018
Braille is a tactile system to represent text. A text in braille consist of several braille cell where each cell represent an alphabet or symbol. A single cell consist of 6 individual dots. Combination of raising high and raising low of these pins compose an alphabet. There is a standard braille code for each alphabet of most of the languages. Generally texts are embossed on paper and visually impaired persons move finger over the dots to read text. Our hypothesis is to keep the users fingers rest over the cell and actuate cell pins in such way that it can make feel like moving finger over cells. In this paper, we will show the design and development of a low cost portable braille book system with only one braille cell along with its experience with the real users. Besides all the available braille devices the challenges was to build such a system in so small space. We tested the device for several months with 10 users. They were able to read through this device and got different feedback from them.

Braille Pad Project: Proposal of a Braille Education Support System using a Tablet Device
International Journal of Asia Digital Art and Design, 2016
In this study, as teaching materials of early Braille education for visually-impaired children, we propose a Braille learning support system, which they play touching Braille by using tablet devices. The proposed system provides auditory and tactile feedback in conjunction with finger movement touching Braille, relying on placing conventional Braille teaching materials on the touchscreen surface of a tablet device. In doing so, the system is effective in point of making user to touch and trace Braille actively and accurately, linking own finger movement with sound. Also, we entertain that the system can be used as motivational teaching material in early stage of Braille education. In addition, because that consists of the system is simplified based on product on products for sale generally and widely distributed in Braille education, the system is estimated using widely. In this paper, we describe about the process of development, system, and system improvement based on user feedbac...
International Journal of Computer Applications
There are diverse tools and equipments which are proving different facilities and features for enhancing the communication skills of the visually impaired people in a great extent. For interpretation of text by the visually impaired persons, most of the devices are designed to simulate the standard Braille display where each character is characterized by six dots (made up of small metals or plastic pins) which could be vertically moved in upper or lower directions mechanically or electronically or through any other mechanism. Also for writing the contents, same standard is followed for building any Braille writer. Analyzing different updated machinery and equipments which support the visually impaired persons for their proper communication with the others, it has been found that these tools provide only some particular facility or feature and that tools sometime may not be sufficient to provide improved support. That is why it is necessary to integrate all different possible communication methods in a single system to cover the different drawbacks in the existing systems and provide a complete solution to those visually impaired people. This paper is the result of analysis of the existing tools and technologies for the enhancement of the communication of the blind people and this paper also proposes a complete system which consists of four different techniques for the blind people to enhance their communication skills. The proposed system consists of a low cost keyboard as Braille writer, a low cost tactile refreshable Braille display (named as SPARSHA), remote communication method through SMS and an Audio output system of the text. This system may provide a complete solution to different communication problem in the visually impaired person's lives.

Optical Character Recognition Based Hand-Held Device for Printed Text to Braille Conversion
In this paper we propose to develop a device that can be used by the visually challenged to read normal English books. Here we focus on letter-by-letter segmentation, recognition and transliteration to the Braille format. The device would use on board software to do the recognition and conversion. The recognized characters are transmitted to the interface which converts the characters to the Braille format which can be felt-read by the visually challenged. The device would be cheaper among its counterparts.
