Pad dot : smart pad device for the bilnd
The blind can not see the visual things.
If someone sends a graph or data to the user, the user can touch the visible data converted by pad dot for example when the class or someone announced. When the blind press a large amount of the braille using a braille tool on the existing market, their hands hurt due to the thick braille paper. The user who has difficulty reading and writing documents can read braille documents, also press the braille.
