Background technology
Chinese character as a kind of pictograph, has significant difference with other various alphabetic writings in the world, and it has thousands of different characters, makes that the user is difficult to the Chinese character of hope is input to such as in computing machine or other the various electronic equipments.Because the quantity of Chinese character is huge, does not also have the keyboard corresponding to various Chinese characters on the reality.Therefore, how Chinese character is imported various device accurately and efficiently and become more and more important.
Because the quantity of Chinese pinyin is less than the quantity of Chinese character far away, the less keyboard that has specific English alphabet of the general use of user, such as English qwerty keyboard, the input Chinese pinyin, convert Chinese pinyin to Chinese character then, finish the input of Chinese character.
Yet, up to the present, the equipment that can carry out Chinese character input easily also mainly is limited to such as the English qwerty keyboard that is used for personal computer etc., and wherein on such keyboard, each button only corresponds respectively to an English alphabet or symbol.For the Chinese character input, the just corresponding English alphabet of Chinese phonetic alphabet.When using this keyboard to carry out the Chinese character input, the user can import Chinese phonetic alphabet by the button of directly pressing on the pairing keyboard of Chinese phonetic alphabet easily according to waiting to import the corresponding Chinese pinyin of single Chinese character.Because this keyboard provides unique input button for each Chinese phonetic alphabet, therefore each input operation of user can be uniquely corresponding to a definite Chinese phonetic alphabet, thereby can easily provide selectable single Chinese character for the user, select the back to confirm the content of input by the user according to this Chinese pinyin.
Though can import Chinese character easily by above-mentioned keyboard,, for number of keys portable set seldom, such as mobile phone, the various Chinese character input methods of prior art but exist very big restriction.
As everyone knows, along with constantly popularizing of mobile phone, the ITU-T keyboard has obtained using widely.The ITU-T keyboard is a kind of QWERTY keyboard, and it mainly comprises numerical key 0-9.These numerical keys can be used for importing telephone number.And some numerical keys are corresponding to 26 letters and be used to import these letters.Such as, numerical key 2 is represented A, B and C; 3 represent D, E and F; 4 represent G, H and I, and 5 represent J, K and L; 6 represent M, N and O; 7 represent P, Q, R and S; 8 represent T, U and V; And 9 represent W, X, Y and Z.
Therefore, in order to import Chinese pinyin, only use above-mentioned several button very inconvenient to mobile phone.
Because the corresponding a plurality of English alphabets of each button on the keyboard, in order to import the letter of a hope, the user must push the certain number of times of a certain button within a certain period of time.Such as, for by an ITU-T keyboard input Pinyin " zhong ", the user must push numerical key 9 four times with input " z ", pushes numerical key 4 secondaries with input " h ", or the like.Import whole phonetic " zhong ", pressing keys 12 times.
The intelligent input method of a kind of afterwards being referred to as " intelligence is keyed in " is developed.The thinking of " intelligence is keyed in " is some impossible letters of filtering automatically, thereby significantly reduces the number of times of pressing keys.Still be example with input Pinyin " zhong ", with above-mentioned same method input " z ".But in order to import " h ", the user only needs the pressing keys numerical key once, and this is because letter " h " letter " g " before is not a legal pinyin combinations with letter " z ".In " intelligence is keyed in " method, but the user only need push 9 buttons with regard to input Pinyin " zhong ".
At present, for mobile phone with ITU-T keyboard or PDA, the most frequently used Chinese character input method is called T9 and E-Zi.They are called " single key entry " input method.In " single key entry " method, the user need not be concerned about the order of letter on each button, in order to import whole phonetic, only need push once for a certain button.Mobile phone or PDA will list all legal pinyin combinations and select for the user.Be example with input Pinyin " zhong " equally, the user only need push in order by numerical key 9-4-6-6-4, and mobile phone will list two candidate pinyin " zhong " and " xiong " selects for the user.For " single key entry " input method, the number of times of user's pressing keys is generally equal to the length of phonetic, but needs an extra selection step.Therefore, also need pressing keys extraly.
Therefore, there is a need in the field to provide a kind of new Chinese character input method, making the user when using the input media input Chinese character of ITU-T keyboard and so on, reducing the required number of times of pushing keyboard of input Pinyin.
