A cost effective electronic braille for visually impaired individuals

Learning process is very difficult for Visually Impaired people as they are unable of receiving visual information. Braille is basically a writing system to aid the visually impaired people. Unfortunately, people of developing or underdeveloped countries cannot afford the available advance electronic braille as they are very expensive. This paper proposes a prototype of affordable Braille display for the blind people to read when an input is given through a computer. Here electromagnetic solenoids are used to facilitate the vertical movement of the dots of the Braille display controlled by an Arduino Uno. This device will be able to guide blind people to read certain patterns of dots in the Braille Cell known as braille alphabets. The study approaches towards the development of a Braille under $100 which will be portable as well as affordable.
