O knihe

Project Report from the year 2018 in the subject Engineering - General, Basics, grade: UG, , language: English, abstract: This project helps in simplifying the process of learning of braille instructions. The integration of physical activity and hearing can facilitate easy learning of Braille Script. In this project we develop a kit which helps the blind and visually impaired people to learn braille even in the absence of teachers.

Braille literacy is crucial for blind individuals, as it enables life-long learning and is key to employment and independency. One way to promote Braille literacy is to make existing Braille reading devices more accessible, affordable, and user friendly. Commercially available Braille reading devices in this regard need various improvements. Most of these devices cost thousands of dollars, mainly because they rely on multiple piezoelectric actuators in order to create the Braille letters.

Other issues include high voltage actuation and reduced portability. In order to solve these issues and improve existing Braille displays, various actuation methods have been widely investigated.285 million people are estimated to be visually impaired worldwide, 39 million are blind and 246 have low vision. India has the largest population of blind people in the world. That's over 12 million people. Even the central and state government provide job opportunities for blind and visually impaired people. But only few vacancies are filled due to lack of education. Lack of education for blind people is due to the lack of qualified teachers to teach them Braille. Learning the Braille script is not an easy task for Visually Impaired students. Visually Impaired students have to memorize various patterns of keys of Braille matrix assigned for different letters/words/symbols in Braille script to read and write effectively.
