A programmer in Hangzhou, Zhejiang Province has created a program that translates braille into Chinese characters. That sounds very useful. Braille is designed specifically for the blind, but it is rather hard for the average person.As we all know,Recognizing braille is very difficult, but it is also an indispensable means for blind people to communicate with the world. This is why this programmer wanted to make this translation tool.It must have been really hard to develop this translation tool, right?The programmer has continually worked on increasing the accuracy of the program before he got the final product. lt was a great invention., We all feel sincere admiration for this. It's hard to imagine how much effort he put into it, but his invention saved a special group and also brought us to the attention of this group.
