Wubi Method - Subdivision of The Keyboard

Subdivision of The Keyboard

The Wubi keyboard assumes a QWERTY-like layout, so users of keyboards implementing a nationalized or alternative layout (such as Dvorak or the French AZERTY) will probably have to do some remapping to make the system sane. Wubi does not position its components arbitrarily: there are far too many of them, and it is only with the introduction of a logical methodology that the system becomes easy to learn.

Basically, the keyboard is divided into 5 zones, each representing a stroke. Those five strokes are falling left, falling right, horizontal, vertical, and hook, and the zones that represent them are QWERT, YUIOP, ASDFG, HJKLM, and XCVBN, respectively. These zones are all laid out horizontally, with the exception of M, which is not in line with the rest of the letters in its zone.

In a general way, the keyboard can be thought of as divided down the center, between T and Y, G and H, and N and M. The keys in each zone are numbered moving away from this dividing line: so we should actually say that in zone QWERT, T is the first letter, R is the second, and E the third; in zone YUIOP, Y is the first, U is the second, I the third, etc. For XCVBN, N is the first, and so on. In HJKLM, consider M to be the last in the series, even though it does not lie on the line.

This is important because components in the first position will have one repetition of the stroke in question (the stroke assigned to the zone in which they belong), those in the second, two, those in the third, three. Those components which are not easily classifiable using this paradigm will be placed on the last letter.

Therefore one would expect 一 to be located on G, and 二 on F, and 三 on D, and indeed, this is the case. Similarly, one would expect 丨 to be located on H, 刂 to be on J, and 川 to be on K. This pattern holds for all the zones. Furthermore, it extends to most radicals that look as though they are made up of three such strokes, even if in fact they might not be at all. An example of this is 中 on K: while it does not have three downward strokes (two only), it appears to have three. Furthermore, it is written by hand by first writing a mouth radical, 口, and then bisecting it with a vertical downward stroke. The mouth radical lies on 'K', so this makes the assignment doubly logical. And the pinyin romanization of 口, kou3, begins with k, another memory aid encoded into the Wubi keyboard.

Furthermore, each letter of each zone has one component associated with it, its "main component". These are usually a complete character (with the exception of X) in their own right. One can always type this main component by typing the letter it is situated on four times. So, for example, the main component of H is 目, and so one would type it by typing "hhhh".

Each letter also has a shortcut character associated with it. In some cases, this character is the same as the component associated with the key in question, and sometimes not. This shortcut character is the character produced when one types just the letter and nothing else; these are all extremely common characters used when typing Chinese.

It is entirely possible that there are a number of components not listed below, either because of oversight, because they are rarely used, or because no simple Unicode representation for the component exists.
