Design and Implementation of Digital Braille System for The Visually Impaired
According to World Health Organization (WHO), there are approximately 2.2 billion people who are visually impaired in the world (Oct, 2019). Braille is a tactile writing system used by people who are visually impaired and is typically written on embossed paper. Reading is the most important form of learning. According to Varao Sousa [11] , reading reduces mind wandering and increases understanding. For visually impaired people, reading refers to braille reading through touch. In this digital age, where everything is done online, the visually impaired have a hard time trying to access digital content or read electronic documents. Digital braille or electronic braille is a way in which the visually impaired can access information using electronic braille displays where the digital content on screen is converted into braille and is made available for use. Many electronic braille systems are printed onto paper and this form of braille is susceptible to wear and tear. Most electronic braille systems used are very expensive especially in developing countries such as India. Hence, we are proposing a digital braille system that is affordable and easy to use. The digital braille system designed converts digital text from documents to braille using python script. The system is driven by electromagnetic push-pull solenoids connected to an Arduino Uno board. The vertical movements of the solenoids represent the braille characters. Each character is read and the corresponding dots representing the character in the braille alphabet is displayed. The system can also be a handy tool for teaching and training the visually impaired people.
BrailleApp - Educational Mobile Application to Assist in the Learning of Braille Language
Proceedings of the 7th International Conference on Computer Supported Education, 2015
Aiming to facilitate the learning process of the Braille System, we developed an educational application to assist people for learning this system. We developed the application initially in Portuguese, it was named as BrailleApp, and it was designed for mobile devices, which uses the Android Platform. All accessibility standards were implemented to make it as accessible as possible to all people, helping visually impaired people and not visually impaired in the learning process of this language. In this first version, the help to learning Braille is specifically to not blind people, although, with some difficulties, it is possible a blind person use the application. In future versions we hope to improve and facilitate the use of this application by blind people too. It is important to emphasize we do not intend to replace the conventional methods which assist in this task, but to be an application to complement the already existing techniques. In an empirical analysis, the results show that the application was positive in the sense of system requirements, functionalities, and accessibility. We expect BrailleApp will be another option to assist users in the teaching-learning process and contribute to the social integration of visually impaired with technologies.
Learning Aid in Braille and Typography
Smart Innovation, Systems and Technologies, 2017
This paper aims to study the existing braille script, highlight their inadequacies in teaching methods for small children and suggest probable solutions. The project focuses mainly on the use of braille and typography together using the existing braille script.In addition, this study is carrying its importance towards the beneficial development for visually impaired children in our society. Thus providing an educational aid. The main idea behind this project is to derive a piece of hardware to use to teach the visually challenged children for future.
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.
BRAILLE TO TEXT AND SPEECH FOR CECITY PERSONS
Visually impaired peoples use braille system for reading and writing. This people are not able to operate computers and other educational software due to this they unable to improve their knowledge. They are comparatively weak than people with clear vision which causes adverse effect on the economic society. One way to improve their knowledge is by introducing a system which can convert braille to word and audio which will improve them to communicate freely with outside world. This system presents the implementation of braille to word and audio converter which is output and word of that particular input. Braille Keypad with different combination of six cells are used an input to system. In this system FPGA kit is used to convert this input to English text and also display it on LCD after decoding English text it converted to audio Keywords: Braille language, blind people, Braille to English word converter.
Design of an electronic prototype to teach braille
Health and Technology, 2019
This work proposes an electronic device to teach Braille. The goal of our prototype is to be a pedagogical strategy to teach Braille to people suffering from visual disability. The teaching process applies to people with visual impairment, while visually deploying to those who support the teaching process. The prototype was tested among two groups of participants and the results are discussed.
