Chinese input methods predate the computer. One of the early attempts was an electro-mechanical [[Chinese typewriter]]
Before the 1980s, Chinese publishers hired teams of workers and selected a few thousand type pieces from an enormous Chinese character set. Chinese government agencies entered characters using a long, complicated list of [[Chinese telegraph code]]s, which assigned different numbers to each character. During the early computer era, Chinese characters were categorized by their radicals or Pinyin romanization, but results were less than satisfactory.
In the 1970s to 1980s, large keyboards with thousands of keys were used to input Chinese. Each key was mapped to several Chinese characters. To type a character, one pressed the character key and then a selection key.<ref>{{cite web |url=https://openstd.samr.gov.cn/bzgk/gb/newGbInfo?hcno=3D8D8DCA190E4CB90399EE2FB91F93CC|title=汉字整字键盘盘面字排列 |website=Standardization Administration of China |year=1987|access-date=2022-08-26}}</ref> There were also experimental "radical keyboards" with dozens to several hundreds keys.

Due to these complexities, there is no "standard" method.
By 1989, [[bopomofo]] and pinyin were available for the [[IBM PC]].<ref name="pournelle198902">{{Cite magazine |last=Pournelle |first=Jerry |date=February 1989 |title=Ready Line Overload |url=https://archive.org/details/eu_BYTE-1989-02_OCR/page/n175/mode/2up?view=theater |access-date=2024-10-08 |magazine=BYTE |pages=121-137}}</ref> In mainland China, pinyin methods such as [[Sogou Pinyin]] and [[Google Pinyin]] are the most popular.

Other methods include [[handwriting recognition]], [[Optical character recognition|OCR]] and [[speech recognition]]. The computer itself must first be "trained" before the first or second of these methods are used; that is, the new user enters the system in a special "learning mode" so that the system can learn to identify their handwriting or speech patterns. The latter two methods are used less frequently than keyboard-based input methods and suffer from relatively high error rates, especially when used without proper "training", though higher error rates are an acceptable trade-off to many users.
