Pocket Braille Keyboard – Reader using Braille Back Service

Abstract

Major disadvantage of Existing Braille Keyboard is the Cost which is greater than 3500$ and size more than 15 cm. Out of 285 million visually impaired people, not many are able to afford it and it’s hefty to carry around. This project presents the making of Pocket Braille Keyboard-Reader of less cost, around 100$, and more compact in size. Principle technologies used are capacitive touch sensing and MEMs (Micro-Electrical Mechanical systems) for typing and reading respectively, which will be assisting the visually impaired people to interact with the world. Ex: Reading and typing in Braille Language, interacting with SMART phone with NAVIGATION keys on the Keyboard.
