Re: Blind people typing Chinese

Larry Wang

If they were born blind they do not know the shape of characters since school of blind do not teach this. So they do not use Wubi.
If they were not born blind, they use wubi because they have already learned Wubi .

I have a question.

How blind people knows, how for example character for sun is written using Wubi keyboard? It is shape based system.

Or, how a chinese blind person know, how to type for example character for xiao flute in Wubi? So, You must know shape of this character, or something, like this.

There are numerous Chinese input methods. This was a key problem when processing Chinese with computers. There are roughly one hunderd thousand number of Chinese characters. About six thousand of them are mostly used in daily life. But there are only about one hunderd keys on keyboard. At first publishing houses use big key board with many keys.
Input methods based on pinyin or zhuyin is not very popular at that time since you need to spend many time on finding the correct character you want to type. Also users at that time mostly rely on word processing jobs, accuracy and efficiency is important.
A man called Wang JiangMin invented WuBi.With that you can type in most Chinese character within four letters, as long as you memorize a set of rules and practice for about a week.
At about 2006, people brought smart prediction into pinyin input methods. The experience of pinyin input methods are much better now. Since most people in mainland China have already learned pinyin in primary school. Other types of input methods which requires additional rules practice start fading away. Few people learn other input methods. Wubi and other input methods are now learned by professionals and enthusiasts. Sougou is the most popular one of these pinyin input methods. But smart prediction is based on collecting your keyborad input data, so there is a privacy issue. Sougou pinyin also pop up advertisement sometimes. So I do not recomment using this. Input methods bundled with operation system is just enough.

Support for microsoft pinyin and wubi is broken in windows 10 and 8.1 so you may find it hard to use.

As for braille.
There are three types of braille in mainland China. Two of them are in NVDA, another one has just been published about a year ago and has not gain popularity yet. However all of them are based on pinyin. They cannot represent the shape of Chinese characters. Most schools for blind in mainland China do not teach how to write Chinese characters. So even if you use braille input, you still have to choose between many candidates. Someone created a braille based on Chinese characters, but it is not widely used. Braille display is more expensive than smart phones and computers and its usage is very limited. Braille has advantage in proof reading and learing but the nature of Chinese braille make braille less appealing for students. Word segmentation and tone mark makes braille even harder to understand. Even braile itself is not popular among blind people in China.
