Low Cost Wireless Electronic Braille Reader

Electronic Braille readers are getting popular worldwide day by day among the visually disabled people. Bangladesh has over half a million blind people and due to the high cost of the available Electronic Braille in the market, most of these people are unable to take advantage of this technology. To make proper use of this technology, a Servo motor based wireless electronic braille was designed. Currently available servo motor based and piezoelectric based braille have some issues with their mechanical features and price respectively. This paper is about the design and construction of a Wireless Electronic Braille Device with resolved mechanical functionality, wireless data transfer availability and much lower cost than available electronic braille of this type. The proposed design ensures correct mechanical functionality, accuracy, security, faster data transfer and lower cost.
