Braille Gloves: An Intelligent Hand-Glove to Generate Bengali Braille Characters for Visually Impaired People

Braille is a writing system that allows the visually impaired people to read by sensing different combination of raised dots on paper. Our system is a two handed braille system that focuses on communication of visually impaired people with computer. Visually impaired people lack in transferring their thoughts due to their incapability to interact with others in social interaction. There are only a few resources printed in braille system. This system will allow the visually impaired people to read any text given as input in the computer. Although Braille Gloves is different from traditional braille in the sense that it needs no braille embosser or any paper, it is easy to understand if one knows braille. The graphical user interface, designed in java, works as the input space and converts each character to Unicode. The six pager motors mounted on fingertips of the index linger, middle finger and ring linger of each hand glove represents six dots in braille. Vibration corresponds to a raised dot. Motors are controlled by an algorithm embedded on Arduino Uno board. The proposed system can convert all Bengali characters efficiently. Experimental results with visually impaired students show that the recognition accuracy is about 90% for single character and 69.4% for the word respectively.
