Chapter 5: Input Methods

e Shouwei Method ( shuwěi shūrùf) is an input method that species the

rst and nal strokes or shapes of an ideograph.

Input by corner

If we ignore the indexing radical and number of strokes of an ideograph, it is still possible

to input them by categorizing the shapes that are at each corner. e Four Corner Code,

which is described in Chapter 11, is typically used for locating characters in ideograph

dictionaries.

However, the ree Corner Code, invented by Jack Huang (黃克東 huáng kèdōng) and

others, is designed specically for character input.

Input by other structures

ere are ways to describe the structure of ideographs that go beyond indexing radicals,

strokes, and corners. Many Chinese input methods take advantage of the fact that ideo-

graphs can be categorized by shapes.

An input method known as the Cangjie Method (倉頡輸入法 cāngjié shūrùf), developed

by Bangfu Zhu (朱邦復 zhū bāngfù), allows the user to input ideographs by radical-like

elements. More details about the Cangjie Method can be found later in this chapter when

its keyboard array is discussed. is input method is commonly used in Taiwan and Hong

Kong. In fact, many dictionaries provide Cangjie codes for hanzi.

Also, the Zheng Code Method ( zhèngm shūrùf), developed by Yili Zheng

( zhèng yìl) and Long Zheng ( zhèng lóng), also uses radical-like elements
