Keyboard for inputting Chinese language

1.1 Technique of inputting Chinese character As the structure of Chinese characters are very different from the relatively simple alphabetic system of western languages, it is very difficult to input Chinese characters into computer quickly and conveniently. There are a few existing systems which include those based on the "PinYin" (phonetic) system, a combination of the PinYin system and character form techniques, whole character encoding, stroke input encoding, and stoke form encoding. The PinYin (Phonetic) system The PinYin encoding system presents several advantages over other systems. First, it is already part of the curriculum of China's primary schools and many people are therefore familiar with the system. Besides, PinYin uses English characters as its encoding characters. Therefore it is a simple matter to directly encode Chinese characters by using standard English character computer keyboards. However, since the output of the PinYin encoding system consists of Chinese characters, and not the PinYin forms of those characters, there are too many degenerate cases. Generally some software processing is used to compensate this effect. For a language such as Chinese, with its many dialects and slangs, there are simply too many Chinese characters for the user to remember or pronounce correctly. The whole character system The whole character keyboard is based on the use of a special hardware keyboard and not the standard English language keyboard. The input speed of this keyboard is comparatively low and is not suitable for wide use. Stroke input encoding system The stroke input encoding system is easy to learn. But it presents too many degenerate cases and is not suitable for entering large amounts of data. Stoke from encoding system The stoke form encoding system is based on a process of first determining the radicals of the characters, then encoding them according to an established set of rules. The stoke form systems developed to date, however, have suffered from the lack of a suitably developed theoretical structure. Therefore, the system still suffers from a large number of synonym codes and slow input speed. It is also difficult to use. The Chinese character strokes and symbols are so different and so complicated that they can be stored and grouped in a wide variety of ways. The conventional keyboard does not support the pictorial characters in Chinese language. There are 3000 to 6000 commonly used pictorial Chinese characters (Hanzi). There are too many dialects and slangs in Chinese which …
