This invention discloses a Chinese
input method using
Pinyin plus a new tone notation on a Western keyboard or keypad to input
Chinese characters, characterized in that the user can input a Chinese compound word (polysyllabic word) containing several syllables and tones by just
keying in a series of letters representing the syllables and tones of the word, and the letters are all joined together without causing any
confusion. This feature is attributed to the new tone
input method of this invention, which is characterized in that the three letters j, q and x are used to input three of the four tones of Putonghua (Mandarin), and “no entry” is used to input the remaining tone. There is a detailed
logical reasoning in the specification of this
patent application explaining how this method can achieve the feature of “syllables with tones are joined together without causing
confusion”. Input of these syllables with tones via just a Western keyboard, together with the important feature of “the syllables with tones are joined together without causing
confusion”, will have a major
impact on the technical field of Chinese
input method.
