If a person is blind and doesn't have sensitive fingertips or doesn't have fingers, then they read Braille characters using their skin?
Background: I am trying to make a Braille device which produces Braille letters from a text file. I have used 6 vibration motors but since it was hard to say which motors were vibrating when I attach them to my hands I am now going to use some mini motors which will push the skin as a dot, which will represent 6 dots of braille letters. Here a user has to only push buttons to forward and backward the chapter and units of any book he want to read. Then the 6 motors will start to vibrate or produce dots now at certain speed.
