Extended data:

(1) Chinese input method, also known as Chinese character input method, refers to the coding method used to input Chinese characters into computers, mobile phones and other electronic devices, and is an important technology in Chinese information processing.

(2) From the logical structure of Chinese characters, Chinese characters can't be divided into a few element units like English, so they can't be classified, placed and processed based on the text structure.

(3) Due to the structural characteristics of Chinese characters, the input of Chinese character glyphs is complicated. This has also led to other transcoding input methods such as pinyin input method. Speech transcoding requires accurate pronunciation of Chinese characters, which are morphemes. Pinyin input method can not directly reflect the characteristics of Chinese characters, and there are many stressed words and polyphonic words in Chinese characters, which objectively has certain obstacles to Chinese pinyin input method.
