Braille cell actuator based teaching system for visually impaired students

There are significant improvement in technology in the last decade that prove important and beneficial to physically disabled people. The technological advancements have helped in achieving several kinds of systems like smart cane assisting in their daily life activities. Smart phones for the blind people are also available with the help of which different gestures can be recognized. There are screen readers as well as an iPhone application for typing in braille on the touch screen. In spite of such inventions, since last so many years and even today, teaching aids like Wooden Boards with Embossed Dots or indentations are used for teaching Braille alphabet to visually impaired students in their School. Currently, with this technique, a single tutor can teach only a single student at a time. This requires considerable amount of time in teaching the alphabet individually to every visually impaired student. Also, the tutor needs special training and prior preparations in order to teach Braille Codes to the students. An innovative approach for mass level teaching of Braille Codes is proposed here where an Embedded System is designed with novel Braille Cell Actuator and Cortex-M4 based microcontroller. With the help of this system, a tutor can teach multiple students at a time that could make the teaching process flexible, faster and easy to use.
