Abstract


This article describes design of a controller for refreshable Braille displays used by Blind or Visually Impaired people. The controller manipulates the ASCII 64 printable character set in order to stimulate 6 dot combinations in Braille language. It is capable of transliterating English/Devanagari texts into Braille script, which is then rendered on a refreshable display. The prototype presented constitutes a portable, battery powered and stand-alone Arduino that processes pre-programmed English/Devanagari text and actuates Braille cells consisting of 6 Light Emitting Diodes representing a Braille character with the incorporation of input buttons and encoders allowing for controlled traversal of text.
