Problems solved by technology

[0009] But obviously these existing input methods are very difficult to use for the blind;

The three fingers of the left and right hands correspond to the three points on the left and right of the Braille character. Correspondingly, relatively speaking, the blind do not need to spend too much time to learn, but it is still very inconvenient because several fingers are often required to press the keys at the same time during operation.
