With the continuous development of society, people's cognition and justification of things around them are getting higher and higher. Often our normal life is colorful, but sometimes we ignore the feelings of a group of special people. They often cannot see clearly and cannot distinguish things. Therefore, based on the daily discrimination of visually impaired people and the problems and difficulties of unclear marking of strange objects, I have made research and design on this problem, A Braille printer for the visually impaired that can mark strange objects around the visually impaired is made, and according to the rewriting of Braille, it is converted into tactile information that the visually impaired can receive and know.
