The Smart Braille keyboard will replace the old style Braille displays which are noisy, slow and utilize expensive technology like piezoelectrics. The Smart Braille Keyboard will be quiet so all type of handicapped people student will be able to use it in a classroom , any outside environment without disturbing others. This project is based on inventing a messenger for the differently disabled set of Humans, who may not be in the position of using mobile phones for messaging or any other kinds of communicating devices, with the satisfactory comfort. This system is linked with a NODE MCU module for the blind person and to establish a way communication path by using a wireless technology. Here the user sends the SMS to the blind person’s mobile app which is able know the SMS using NODE MCU module through inbuilt wifi shield commands and then converts the characters of the SMS into the Braille language using the lookup table present in its memory. Voice play back and OCR are the main enhancements in this concept. Raspberry integrated with camera implements OCR process for disabled people.
