CKC Chinese Input System

The CKC Chinese Input System is a Chinese input method for computers that uses the four corner method to encode characters.

The encoding uses a maximum of 4 digits ("0" - "9") to represent a Chinese character. All possible shapes of strokes that forms any given Chinese character are classified into 10 groups, each represented by one of the ten possible digits 0-9. Chinese characters can then be input by following the order in which the strokes are identified at the 4 corners of the character. As a result of this simplicity in coding using the ten numeric digits, users typically need to use only a numeric keypad to input Chinese.

Implementations for both Traditional and Simplified Chinese are available though the coding principle applies to both. In other words, users only need to be trained once and the skill can be applied equally well to both Traditional and Simplified Chinese version of the CKC Chinese Input System.

Training courses on the CKC Chinese Input System are provided by training centres in CKC Centre for the Development of Information Technology for Chinese Language Teaching of The Hong Kong Institute of Education, IVE Haking Wong and of Hong Kong University

Famous quotes containing the words input and/or system:

    Family life is not a computer program that runs on its own; it needs continual input from everyone.
    Neil Kurshan (20th century)

    The United States is unusual among the industrial democracies in the rigidity of the system of ideological control—”indoctrination” we might say—exercised through the mass media.
    Noam Chomsky (b. 1928)
