Braille relates to print in so many ways, like in elevators there are, you know, like, the arrows that say out or in, to close doors, and things like that. And it relates to print because, like, an arrow, you know, it usually points, you know, up, down, left, or right, and in braille it’s six cells, and what they do is they…different signs mean different things. So if you put them in a certain position, one dot is going to be by itself pointing a certain way, like, if it’s by itself, and it’s an elevator, and it’s two dots behind it, you would know, oh, this is the beginning of the arrow going this way, by the dot by itself.
