A cheap robot in the form of a braille dicta-teacher could be the answer to helping India's impoverished visually impaired population. Project Mudra hopes to improve literacy in Indian slums where 8 million blind people reside. While there are many resources for the blind that use braille, knowledge of braille can be a gap in developing countries. Created by computer science students, the $150 braille display will provide access to information and contact with the outside world.
The braille dicta-teacher has a browse feature that takes vocal input and translates it to tactile text. In auto mode, the user can learn through a 'predetermined, sequential audio-tactile output.' Project Mudra technology uses a combination of braille hardware, raspberry pi and python.
