Abstract

The present invention is a method for inputting Chinese characters into a computer system, by using the 26 alphabet keys on a standard English keyboard to arrange Chinese consonants, vowel codes, codes of the initial two strokes and the last two strokes of a Chinese character, and inputting Chinese characters or phrases according to their Pinyin (phonetic symbol) and writing sequence. The present invention provides both the input method which is mainly based on consonants and vowels, secondly on the initial two strokes and the last two strokes of the characters and the input method which is mainly based on the initial two strokes and the last two strokes of the characters, and secondly on their consonants and vowels.

Claims

1. A method for inputting Chinese characters into a computer system having a standard English keyboard, the keyboard including 26 alphabet keys on which Chinese consonants, vowels and 25 stroke combinations of the characters are allocated wherein each stroke combination represents two strokes or codes of two strokes, the characters being coded primarily according to their consonants and vowels or vowel codes, and secondly according to initial two strokes and last two strokes of the characters by using said stroke combination, said method comprising the steps of:

(A) entering single Chinese characters by

a) inputting the consonant of each character,

b) inputting the vowel code of said character,

c) inputting codes of the initial two strokes of said character,

d) inputting codes of the last two strokes of said character; and

(B) entering words or phrases of two Chinese characters by,

a) inputting the consonant of the first character of each word,

b) inputting the consonant of the second character,

c) inputting codes of initial two strokes of the first character,

d) inputting codes of last two strokes of the second character.

2. The method according to claim 1, wherein characters having less than four strokes are entered by the following steps:

a) for one-stroke characters " " and " ", inputting " " and " ", respectively;

b) for two-stroke characters, inputting the two strokes as codes of the initial two strokes and the last two strokes,

c) for three-stroke characters, inputting the first and second stroke as codes of the initial two strokes and inputting the second and third strokes as codes of the last two strokes.

3. A method for inputting Chinese characters into a computer system having a standard English keyboard, the keyboard including 26 alphabet keys on which Chinese consonants, vowels and 25 stroke combinations of the characters are allocated wherein each combination represents two strokes or codes of two strokes, the characters being coded primarily according to their initial two strokes and last two strokes, and secondly according to their consonants and vowels or vowel codes, said method comprising the following steps:

(A) entering single Chinese characters by

a) inputting codes of the initial two strokes of each character,

b) inputting codes of the last two strokes of said character,

c) inputting the consonant of said character, and

d) inputting a code of vowel of said character;

(B) entering words or phrases of two Chinese characters by

a) inputting codes of the initial two strokes of the first character of each word or phrase,

b) inputting codes of the last two strokes of the first character,

c) inputting codes of the initial two strokes of the second character,

d) inputting codes of the last two strokes of the second character;

(C) entering words or phrases of three Chinese characters by

a) inputting codes of the initial two strokes of the first character of each word or phrase,

b) inputting codes of the initial two strokes of the second character,

c) inputting codes of the initial two strokes of the third character,

d) inputting a letter "O"; and

(D) entering words or phrases of four Chinese characters by

a) inputting codes of the initial two strokes of the first character of each word or phrase,

b) inputting codes of the initial two strokes of the second character,

c) inputting codes of the initial two strokes of the third character,

d) inputting codes of the initial two strokes of the fourth character, and

(E) entering words or phrases of more than four Chinese characters by

a) inputting codes of the initial two strokes of the first character of each word or phrase,

b) inputting codes of the initial two strokes of the second character,

c) inputting codes of the initial two strokes of the third character, and

d) inputting codes of the initial two strokes of the last character.

4. The method according to claim 3, wherein characters having less than four strokes are entered by the following steps:

a) for one-stroke characters " " and " ", inputting " " and " ", respectively;

b) for two-stroke characters, inputting the two strokes as codes of the initial two strokes and the last two strokes,

c) for three-stroke characters, inputting the first and second stroke as codes of the initial two strokes and inputting the second and third strokes as codes of the last two strokes.
