Fig. 2 is the process flow diagram of contents processing (characters input method) that the character entry apparatus of embodiments of the present invention 1 is shown.
Next, action is described.
The example of retrieving " the bright lavipeditum in east " as the facility title is described herein.
If represent the pronunciation of " the bright lavipeditum in east " with phonetic, be " DONG FANG MING ZU YU ".
The user at first operates input mode and selects receiving portion 3 when retrieval facility title, selects the input mode of character input.
In present embodiment 1, as mentioned above, from 4 kinds of input modes (hand-written character input mode, spelling input mode, Two bors d's oeuveres input mode, simple pinyin input mode), select the input mode of expectation.
Input mode selects receiving portion 3 to accept the input mode of being imported by the character of user's selection, and this input mode is notified to character input receiving portion 4(step ST1).
If the user has selected the input mode of character input, then begin input character.
If character input receiving portion 4 selects receiving portion 3 to receive the notice of input mode from input mode, output to the 5(of candidate search portion step ST2 then according to the character of this input mode acceptance by user's input, and with this character).
Do not selecting receiving portion 3 to receive the notice of input mode and imported by the user under the situation of character from input mode, the input of accepting character according to input mode or the input mode identical with last time of initial setting.
For example, selecting to import " DONG FANG MING ZU YU " as phonetic successively under the situation of spelling input mode as the input mode of character input.
Fig. 3 is the key diagram that the searching picture example of the situation of having selected the spelling input mode is shown, the stage that the input that in the example of Fig. 3, shows " D " has been finished.
For example, having selected under the situation of Two bors d's oeuveres input mode as the input mode of character input, if accepted the input of the initial consonant in the phonetic, then input is connected on this initial consonant simple or compound vowel of a Chinese syllable afterwards.
Fig. 4 is the key diagram that the searching picture example of the situation of having selected the Two bors d's oeuveres input mode is shown, and in the example of Fig. 4, owing to imported " D ", is shown as the character that can import so be connected on " D " simple or compound vowel of a Chinese syllable such as " ong " afterwards.
For example, under the situation of having selected simple pinyin input mode as the input mode of character input, the input expression constitutes initial (alphabet) i.e. " D ", " F ", " M ", " Z ", " Y " of phonetic of pronunciation of each Chinese character " east ", " side ", " bright ", " foot ", " bath " of facility title successively.
Fig. 5 is the key diagram that the searching picture example of the situation of having selected simple pinyin input mode is shown, the stage that the input that in Fig. 5, shows " D " has been finished.
For example, selecting under the situation of hand-written character input mode as the input mode of character input the hand-written character of each Chinese character " east " of the facility of input formation successively title, " side ", " bright ", " foot ", " bath ".
Fig. 6 is the key diagram that the searching picture example of the situation of having selected the hand-written character input mode is shown, the stage that the input that in Fig. 6, shows the hand-written character in " east " has been finished.
The Chinese word character candidate (step ST3) 1 or more corresponding with this character with reference to the Chinese word character dictionary of preserving in the dictionary preservation portion 1, retrieves in candidate search portion 5 when having accepted the input of character by character input receiving portion 4.
For example, under the situation of having selected the spelling input mode as the input mode of character input, as shown in Figure 3, in the stage that the input of phonetic " D " has been finished, as the Chinese word character candidate corresponding with phonetic " D ", retrieve " east ", " " etc.
For example, selecting under the situation of Two bors d's oeuveres input mode as the input mode of character input, as shown in Figure 4, in the stage of having imported the initial consonant in the phonetic " D ", as the Chinese word character candidate with initial consonant " D ", retrieval " east ", " " etc., as be connected on afterwards " east " of initial consonant " D ", " " simple or compound vowel of a Chinese syllable that waits, definite " ong ", " e " etc.
For example, under the situation of having selected simple pinyin input mode as the input mode of character input, as shown in Figure 5, in the stage that the input of letter " D " has been finished, as be the Chinese word character candidate of initial with letter " D ", retrieve " east ", " " etc.
For example, selecting under the situation of hand-written character input mode as the input mode of character input, as shown in Figure 6, as the Chinese word character candidate corresponding with the character of handwriting input, retrieval " east ", " bed " etc.
In addition, under the situation of hand-written character input mode, character input receiving portion 4 is accepted input at each picture of character, candidate search portion 5 is when having accepted the input of a picture by character input receiving portion 4, the character of importing is predicted the Chinese word character candidate more than 1 that retrieval is corresponding with this prediction character.
If candidate search portion 5 retrieves the Chinese word character candidate 1 or more corresponding with the character of having been accepted input by character input receiving portion 4, then from the character string by 2 storages of character string storage part, retrieval comprises this Chinese word character candidate's the character string candidate more than 1 (step ST4).
For example, selecting the input mode of spelling input mode as the character input, and retrieved as the Chinese word character candidate corresponding with phonetic " D " as shown in Figure 3 " east ", " " situation under, retrieve the character string candidate more than 1 that comprises " east ", comprise " " the character string candidate more than 1 etc.
In the example of Fig. 3, as the character string candidate who comprises " east ", the retrieval " Oriental Pearl's tower ", " the bright lavipeditum in east ", as comprise " " character string candidate, the retrieval " taxi dining room ".
If candidate search portion 5 retrieves Chinese word character candidate and the character string candidate more than 1 more than 1, then candidate display portion 6 is as Fig. 3～shown in Figure 6, with the Chinese word character candidate more than 1 and the character string candidate display more than 1 in the same picture (step ST5).
The user confirms that by candidate display portion 6 picture displayed from the Chinese word character candidate and character string candidate more than 1 that show, the operation candidate selects receiving portion 7, selects Chinese word character candidate or character string candidate (step ST6) in this picture.
If selected the Chinese word character candidate by the user, then the candidate selects receiving portion 7 to accept this Chinese word character candidate, and this Chinese word character candidate is saved in historical DB 8, and the meaning that will accept Chinese word character candidate's selection is notified to candidate search portion 5.
On the other hand, if selected the character string candidate by the user, then this character string candidate is outputed to candidate search portion 5.
In the example of Fig. 3, from " east ", " " etc. the character string candidate such as Chinese word character candidate or " Oriental Pearl's tower ", " the bright lavipeditum in east ", " taxi dining room ", select 1 Chinese word character candidate or 1 character string candidate.
If the notice of the meaning of Chinese word character candidate's selection is selected receiving portion 7 to receive to have accepted by candidate search portion 5 from the candidate, then from historical DB 8 take out the Chinese word character candidate that selected (below, be called " determining Chinese word character "), from the character string candidate who has retrieved, screening comprises the character string candidate who determines Chinese word character, and this character string candidate is outputed to the 6(of candidate display portion step ST7).
For example, selection the Chinese word character candidate who is selected receiving portion 7 acceptance " east " by the candidate, and definite Chinese word character only is under the situation in " east ", from character string candidates such as " Oriental Pearl's tower ", " the bright lavipeditum in east ", " taxi dining room ", the screening comprise " east " character string candidate of order Chinese character really, only will comprise " east " really the character string candidate of order Chinese character output to candidate display portion 6.
If receiving from candidate search portion 5, candidate display portion 6 comprises " east " character string candidate of order Chinese character really, then the deletion do not comprise " east " really the order Chinese character character string candidate (for example, comprise " " character string candidate), only show to comprise " east " character string candidate of order Chinese character (step ST8) really.
Afterwards, turn back to the processing of step ST2, repeat to implement same processing.
Herein, show and determine that Chinese word character only is the example in " east ", but for example selected receiving portion 7 to accept the Chinese word character candidate's of " side ", " bright " selection by the candidate, and definite Chinese word character is under the situation of " east ", " side ", " bright ", from character string candidates such as " Oriental Pearl's tower ", " the bright lavipeditum in east ", the screening comprise " east ", " side ", " bright " the character string candidate of order Chinese character really, only will comprise " east ", " side ", " bright " really the character string candidate of order Chinese character output to candidate display portion 6.
Comprise " east ", " side ", " bright " the character string candidate of order Chinese character really if candidate display portion 6 receives from candidate search portion 5, then only show to comprise " east ", " side ", " bright " the character string candidate of order Chinese character really.
In addition, candidate search portion 5 is being selected receiving portion 7 to accept under character string candidate's the situation of selection by the candidate, and the facility name that this character string candidate is represented is referred to as result for retrieval and outputs to guider (step ST9).
For example, selected receiving portion 7 to accept under character string candidate's the situation of selection of expression " the bright lavipeditum in east " by the candidate, " the bright lavipeditum in east " that this character string candidate is represented outputs to guider as result for retrieval.
Herein, if the character string candidate that screening character string candidate and showing has screened, then turn back to the processing of step ST2 and accept the input of character, even but in the way of input character, also can switch the input mode of character input, even if after input mode selection receiving portion 3 has been accepted the selection of input mode for the time being, so long as selected just can to accept the selection again of input mode before receiving portion 7 accepts character string candidate's selection by the candidate.
That is, also can turn back to the processing of step ST1, select receiving portion 3 to accept the selection of the input mode of character input by input mode.
For example, the user operates input mode and selects receiving portion 3 to select the spelling input mode, even coming by the spelling input mode in the way of input Pinyin, also can accept the selection again of other input modes (Two bors d's oeuveres input mode, simple pinyin input mode, hand-written character input mode).
From as can be known above, according to present embodiment 1, possess: candidate search portion 5, when having accepted the input of character by character input receiving portion 4, retrieve the Chinese word character candidate 1 or more corresponding with this character, and from the character string by 2 storages of character string storage part, retrieval comprises this Chinese word character candidate's the character string candidate more than 1; Candidate display portion 6 will be by the Chinese word character candidate more than 1 of candidate search portion 5 retrieval and character string candidate display in same picture; And the candidate selects receiving portion 7, from the Chinese word character candidate and character string candidate more than 1 that are shown by candidate display portion 6, accept Chinese word character candidate or character string candidate's selection, wherein, candidate search portion 5 is being selected receiving portion 7 to accept under Chinese word character candidate's the situation of selection by the candidate, from the character string candidate who has retrieved, screening comprises this Chinese word character candidate's character string candidate, and this character string candidate outputed to candidate display portion 6, accepted under character string candidate's the situation of selection being selected receiving portion 7 by the candidate, the facility name that this character string candidate is represented is referred to as result for retrieval and exports, so thereby play the effect that the input number of times that can reduce character is retrieved the facility title efficiently.
Namely, candidate display portion 6 will be by the Chinese word character candidate more than 1 of candidate search portion 5 retrieval and character string candidate display in same picture, even so in the way of input character, also can confirm the result for retrieval (by the character string candidate of candidate search portion 5 retrievals) of facility title.Therefore, even do not import the alphabet that constitutes the facility title, also can retrieve the facility title of expectation, can retrieve the facility title efficiently.
In addition, candidate search portion 5 is being selected receiving portion 7 to accept under Chinese word character candidate's the situation of selection by the candidate, from the character string candidate who has retrieved, screening comprises this Chinese word character candidate's character string candidate, and this character string candidate outputed to candidate display portion 6, so the user can find the facility title of expectation simply.
In addition, according to present embodiment 1, even if after input mode selection receiving portion 3 has been accepted the selection of input mode for the time being, so long as selected by the candidate before receiving portion 7 accepts character string candidate's selection, just can accept the selection again of input mode, so play the effect that can improve the convenience of user when using character.

In addition, candidate display portion 34 implements the following processing: be set at character entry apparatus under the situation of the search modes that the point of crossing of a plurality of roads is retrieved, in the character string candidate's who has shown the title of representing certain road picture, show the character string candidate more than 1 by 33 retrievals of candidate search portion.
In addition, candidate display portion 34 has constituted the candidate display unit.
Next, action is described.
In present embodiment 4, be described as follows situation: the user operates not shown user interface, is set at the search modes that the point of crossing of a plurality of roads is retrieved.
Figure 10 is the key diagram that is illustrated in when the point of crossing of 2 roads retrieved an example of the different kinds of roads searching picture that the character string candidate to the title of representing each road retrieves.
In Figure 10, the title that shows title to road and be the character string candidate on " amrita road " and road is the example that the character string candidate on " waterside town road " retrieves.
, the example of the character string candidate of retrieval expression " waterside town road " after retrieving the character string candidate who represents " amrita road " is described herein, but also can after retrieving the character string candidate who represents " waterside town road ", retrieves the character string candidate of expression " amrita road ".
If represent the pronunciation on " amrita road " with phonetic, then be " XIAN LOU LU ".
In addition, if represent the pronunciation on " waterside town road " with phonetic, then be " SHUI CHENG LU ".
At first, the user is under the situation of retrieval " amrita road ", and the operation input mode is selected receiving portion 3, selects the input mode of character input.
In present embodiment 4, with above-mentioned embodiment 1 similarly, from 4 kinds of input modes (hand-written character input mode, spelling input mode, Two bors d's oeuveres input mode, simple pinyin input mode), select the input mode of expectation.
Input mode is selected receiving portion 3 and above-mentioned embodiment 1 similarly, accepts the input mode by the character input of user's selection, and this input mode is notified to character input receiving portion 4.
If the user has selected the input mode of character input, the then input of beginning character.
If character input receiving portion 4 selects receiving portion 3 to receive the notice of input mode from input mode, then with above-mentioned embodiment 1 similarly, accept character by user's input according to this input mode, and this character outputed to candidate search portion 33.
Selecting receiving portion 3 receiving the notice of input mode from input mode, and imported by the user under the situation of character, the input of accepting character according to input mode or the input mode identical with last time of initial setting.
For example, selecting under the situation of spelling input mode as the input mode of character input, input is as " the XIAN LOU LU " of the phonetic on " amrita road " successively.
The Chinese word character candidate 1 or more corresponding with this character similarly when accepting the input of character by character input receiving portion 4, with reference to the Chinese word character dictionary of preserving in the dictionary preservation portion 1, retrieves in the candidate search portion 5 of candidate search portion 33 and Fig. 1.
If candidate search portion 33 retrieves the Chinese word character candidate 1 or more corresponding with the character of having been accepted input by character input receiving portion 4, then in the character string of the title of the expression road from the character string of being stored by character string storage part 2 or server 21, retrieval comprises this Chinese word character candidate's the character string candidate more than 1.
If candidate search portion 33 retrieves Chinese word character candidate and the character string candidate more than 1 more than 1, then the candidate display portion 6 of candidate display portion 34 and Fig. 1 similarly arrives the Chinese word character candidate more than 1 and the character string candidate display more than 1 in the same picture.
The user confirms that by candidate display portion 34 picture displayed from the Chinese word character candidate and character string candidate more than 1 that show, the operation candidate selects receiving portion 7 to select Chinese word character candidate or character string candidate in this picture.
The candidate selects receiving portion 7 when having selected the Chinese word character candidate by the user, with above-mentioned embodiment 1 similarly, accept this Chinese word character candidate, this Chinese word character candidate is saved in historical DB 8, and the meaning that will accept Chinese word character candidate's selection is notified to candidate search portion 33.
On the other hand, if selected the character string candidate by the user, then this character string candidate is outputed to candidate search portion 33.
Afterwards, till selecting the character string candidate by the user, repeat to implement and above-mentioned same processing.
If select receiving portion 7 to accept the character string candidate's on expression " amrita road " selection by the candidate, then candidate search portion 33 is with reference to by map data base 31 map data stored, the character string candidate more than 1 of the title of the road that retrieval expression and this road intersect.
If candidate search portion 33 retrieves the character string candidate more than 1 of the title of the road that expression intersects with road (amrita road) with reference to map datum, then candidate display portion 34 as shown in figure 10, in the picture that has shown " amrita road ", show the character string candidate more than 1.
At this moment, candidate display portion 34 shows successively from the character string candidate who exists with the near position of current location.
The user confirms that by candidate display portion 34 picture displayed from the character string candidate more than 1 who shows, the operation candidate selects receiving portion 7 to select the character string candidate in this picture., be made as the character string candidate of retrieval expression " waterside town road " herein, so select the character string candidate of expression " waterside town road ".
When having been selected the character string candidate on expression " waterside town road " by the user, the candidate selects receiving portion 7 to accept this character string candidate's selection, and this character string candidate is outputed to candidate search portion 33.
Thus, guider can be retrieved the point of crossing on " amrita road " and " waterside town road ".
But, the character string candidate's who is retrieved by candidate search portion 33 quantity is more, so can't see showing all character string candidates simultaneously under character string candidate's the situation of expectation, the user can import the character that receiving portion 4 is imported the character string candidate who constitutes expectation by operational character, thus screening character string candidate.
, be made as the character string candidate of retrieval expression " waterside town road " herein, so for example selecting under the situation of spelling input mode as the input mode of character input, the pronunciation of input " waterside town road " is phonetic " SHUI CHENG LU " successively.
In addition, selecting under the situation of hand-written character input mode as the input mode of character input, successively the hand-written character on input " water ", " city ", " road ".
When accepting the input of character by character input receiving portion 4, the Chinese word character candidate 1 or more corresponding with this character retrieves with reference to the Chinese word character dictionary of preserving in the dictionary preservation portion 1 in candidate search portion 33.
If candidate search portion 33 retrieves the Chinese word character candidate 1 or more corresponding with the character of having been accepted input by character input receiving portion 4, then from the character string candidate more than 1 (comprise " waterside town road " etc. character string candidate) of retrieval before, screening comprises this Chinese word character candidate's the character string candidate more than 1, and this character string candidate is outputed to candidate display portion 34.
If candidate display portion 34 receives the character string candidate who has been screened by candidate search portion 33, then only show the character string candidate who has screened.
Until the character string candidate display of expectation in picture and till finding the character string candidate of expectation, accept the input of character and screen the character string candidate.
