Abstract

PURPOSE:To realize the handwritten KANA (Japanese syllabary)/KANJI (Chinese character) conversion with a small number of operating steps by providing a conversion execution control part to designate the KANA/KANJI conversion to the result candidates of recognition which are displayed at a recognition result display part. CONSTITUTION:A KANA character string supplied to a handwritten character entry part 1 is recognized by a recognizing part 3 and the recognition result candidates are held by a recognition result holding part 4 for each character. Then a first recognition result candidate of each character is displayed at a recognition result display part 5. In this case, an instruction is given to a KANA /KANJI converting part 8 from a conversion execution control part 12 for execution of the KANA/KANJI conversion processing to the character string which is presently displayed at the part 5. The result of this conversion is displayed at a conversion result display part 10. In case, the recognition result candidate displayed at the part 5 is changed to the next candidate by a next recognition candidate selecting part 6, the part 12 instructs the KANA/KANJI conversion to said next candidate. Then the result of this conversion is displayed at the part 10.

Description

[Detailed Description of the Invention] [Summary] This invention relates to an integrated control method for handwritten kana character recognition processing and kana-kanji conversion processing in a character input device that inputs kanji characters by combining handwritten kana human power and kana-kanji conversion.

The purpose of this study is to realize a control method that enables handwritten kana-kanji conversion with a small number of operation steps.

A conversion execution management unit is established to control the execution of kana-kanji conversion.
The conversion execution management unit is activated by an instruction for kana-kanji conversion, and instructs the kana-kanji conversion unit to perform kana-kanji conversion processing on the first candidate of the recognition result when the recognition unit finishes the recognition process. In addition, when the recognition next candidate selection section changes the displayed recognition result candidate to the next candidate, control is performed to instruct the kana-kanji conversion process for the changed next candidate.

[Industrial application field]

The present invention relates to a nine character input device.

In particular, the present invention relates to an integrated control system for handwritten kana character recognition processing and kana-kanji conversion processing in a character input device that inputs kanji by combining handwritten kana character input and kana-kanji conversion.

[Conventional technology]

Devices for inputting kanji use a method in which keys are pressed on a kana keyboard and converted into kanji, or a method in which kanji are handwritten and recognized by the device. In the former case, it takes time and burden for the user to input until he or she remembers the keyboard layout, while in the latter case input becomes difficult when the user cannot remember the kanji.

There is also a method of using both methods in combination to convert kana to kanji using a keyboard when you cannot remember a kanji, but this also leaves the problem of the former unresolved.

In the figure, 1 is a handwritten character entry section, and 2 is a recognition instruction section.

3 is a recognition unit, 4 is a recognition result holding unit, 5 is a recognition result display unit that displays one of the recognition results, and 6 is a recognition next candidate selection unit that instructs display of the next candidate in case of erroneous recognition.

7. Fanatical kanji conversion instruction section, 8. Fanatical kanji conversion section.

9 is a conversion result holding section, 10 is a conversion result display section that displays one of the conversion results, and 11 is a conversion next candidate selection section that instructs the display of a homophone opposition word.

FIG. 5 shows a processing flow diagram of the conventional method shown in FIG.

In this conventional method, the user's instructions when converting 9 handwritten kana-kanji characters are as follows: ■ Recognition instruction, ■ Display next recognition candidate if necessary, ■ Conversion instruction, ■ Display next conversion candidate if necessary.
Requires variety.

Hereinafter, the steps (11 to α
D, the operation of the conventional method shown in FIG. 4 will be specifically explained.

(1): The user inputs, for example, the notation of the kanji that he or she wants to input.

From the handwritten character entry section 1, handwritten entries are made in kana characters.

(2): Next, the user issues a recognition instruction from the recognition instruction section 2.

(3): The recognition unit 3 recognizes nine handwritten kana character strings according to the recognition instruction, and stores the recognition results in the recognition result holding unit 4.

(4): Display one of the recognition result characters (assuming there are a plurality of characters) in the recognition result storage unit 4 on the recognition result display unit 5 as a candidate character.

(5) The second user looks at the displayed candidate characters of the recognition results and judges whether they are correct or not. If the answer is correct (YES)
Executes (7), and if it is an error (No).

Execute (6).

(6): In the case of an error, the user instructs the recognition result holding unit 4 from the recognition next candidate selection unit 6 to display the next candidate character, and (
Repeat the operations from 4).

(7): When the candidate character string is correct: First, the user instructs the kana-kanji conversion unit 8 to perform kana-kanji conversion from the conversion instruction unit 7.

(8): The kana-kanji conversion unit 8 performs kana-kanji conversion processing on the character string determined to be correct, and stores the result in the conversion result holding unit 9.

(9): Extract only one candidate kanji word/phrase from the conversion result stored in the conversion result storage section 9 and display it on the conversion result display section 10.

0 [: The user selects 8 if the displayed candidate kanji is correct (
YES), exit (return to 11), and if it is an error (No)
, execute αυ.

Qll: The user issues a next candidate display instruction from the conversion next candidate selection section 11, and returns to (9) to repeat the operation.

The above operations are executed every time a winter coat is input.

[Problem that the invention seeks to solve]

In the case of the conventional method, the processing stage for recognizing handwritten kana characters and the processing stage for kana-kanji conversion are completely independent, and at each stage, instructions for recognition or conversion processing,
Since it is necessary to recognize the correct answer and give instructions for displaying secondary candidates, there is a problem in that the number of operation steps required by the user increases.

An object of the present invention is to realize a control method that enables handwritten kana-kanji conversion with a small number of operation steps.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a control mode in which two handwritten kana character recognition processes and a kana-kanji conversion process can be executed continuously, and allows the user to instruct both recognition and conversion with a single operation. be.

FIG. 1 shows the basic configuration of the present invention.

In the figure, 1 is a handwritten character entry section, 2 is a recognition instruction section, 3 is a recognition section, 4 is a holding section for recognition results, and 5 is a display for one of the recognition results! ! The recognition result display receiving unit 6 is a recognition next candidate selection unit that instructs display of the next candidate in case of erroneous recognition, and the conversion unit 7 is a conversion unit that instructs both recognition and conversion.

Holding section, 8 Ephemeral Kanji conversion section, 9 Conversion result holding section, 1
0 is a conversion result display section that displays one of the conversion results, 11 is a conversion next candidate selection section that instructs to display a homophone opposite word,
Reference numeral 12 denotes a conversion execution management unit which, when a conversion instruction is given, waits for the completion of recognition or selection of the next candidate for recognition, requests execution of kana-kanji conversion, and requests adjustment of the recognition result display position.

[Effect]

The basic principle of the present invention will be described.

In the conventional method, the user recognizes the recognition result, selects the next candidate in case of incorrect recognition, and when the correct kana character string is obtained, the user instructs execution of kana-kanji conversion.

On the other hand, in the present invention, the user does not issue a conversion instruction at the time of kana-kanji conversion (instead, the user issues an instruction to perform recognition and then conversion in one operation, and in response, the device performs recognition. Immediately after that, Kana-Kanji conversion is automatically performed for the first candidate character string, and when the next recognized candidate is selected, Kana-Kanji conversion is automatically performed again for that candidate character string.

This allows you to always see the currently displayed recognition result and the kana-kanji conversion result for that character string.

- will be displayed together.

〔Example〕

An embodiment of the present invention will be described according to the configuration shown in FIG.

Fig. 2 is a processing flow diagram of this embodiment, and Fig. 3 is a processing flow diagram of the first embodiment.
It is a processing flow diagram of the conversion execution management unit 12 in the figure.

First, the overall operation of the ninth embodiment will be explained in accordance with steps (a) to j) of the processing flow shown in FIG.

If the user wants to enter a kana character string in the handwritten character entry section 1, a
), when the conversion instruction section 7 issues an instruction (b).

The characters that were filled in! ! It is recognized by the recognition unit (C).

Since recognition result candidates are obtained for each written character, these candidates are held in the recognition result holding unit 4, and a character string in which the first recognition result candidates for each character are connected is displayed in the recognition result display unit 5. (d).

At this time, in response to a request from the conversion execution management section 12, the recognition result is displayed in an appropriate screen area, avoiding the normal display position of the text.

At the same time, in response to a request from the conversion execution management section 12, the kana-kanji conversion section 8 performs kana-kanji conversion on the kana character string currently displayed on the recognition result display section 5 (e).

Since homophones also exist in the conversion, these conversion candidates are temporarily held in the conversion result holding section 9, and only the first conversion candidate is displayed on the conversion result display section 10 (f).

The user judges whether the recognition is correct or incorrect (g), and if there is an incorrect recognition (h), the user indicates the incorrectly recognized character in the recognition next candidate selection section 6 (j).

The character is replaced with the next recognition candidate (d).

At the same time, in response to a request from the conversion execution management section 12, the kana-kanji conversion section 8 targets the kana character string currently displayed by the recognition result display section 5.

Perform kana-kanji conversion (e).

At the time when a correct kana character string is obtained by repeating the selection of the next candidate based on the recognition result, the correct conversion result or its homophone is displayed on the conversion result display section 10.

If the kanji string displayed in the conversion result display section IO is a homophone (h), the user instructs the conversion next candidate selection section 11 (i) to select this kanji string as the next conversion candidate. (f).

A correct conversion result is obtained by repeatedly selecting the next candidate for the conversion result.

Therefore, the user's instructions may be of three types: (1) a conversion instruction, (2) an instruction to display a recognition next candidate if necessary, and (2) an instruction to display a conversion next candidate if necessary.

Note that when simply inputting characters without kana-kanji conversion, recognition is performed by the user issuing an instruction from the recognition instruction unit 2 after inputting. In this case, no conversion is performed, so the recognition result is displayed within the sentence. Of course, in the case of erroneous recognition, display of the next candidate can be instructed from the recognition next candidate selection section 6.

Next, detailed operations of the conversion execution management section 12 will be explained with reference to FIG.

When the conversion execution management section 12 first receives a conversion instruction from the conversion instruction section 7 (k), it waits for the end of the recognition process in the recognition section 3, and when it is notified of the end of recognition (l).

A request is sent to the recognition result display unit 5 to adjust the display position so that both the recognition result and the conversion result can be viewed at the same time (m), and then the kana-kanji conversion process for the displayed recognition result is performed. Instructs the kana-kanji converter 8. The conversion result will be displayed.

When the user instructs selection of the next recognition candidate, the conversion execution management unit 12 instructs the kana-kanji conversion unit 8 to convert the updated recognition result.

Next, a specific example of the operation according to this embodiment will be explained.

There are already users.

It is assumed that up to

Next, enter ``dog'' as 1 and instruct recognition, and the recognition result will be displayed in the sentence.

This is just recognition without transformation. If there is an erroneous recognition at this point, an instruction is given to display the next recognition candidate.

After this, I want to input ``R pet'', but I don't know the kanji, so I input ``Kau J.'' When I give a conversion instruction here, recognition is performed first, and for ``Ka J, I get ``Ka j'' as a recognition result. Assume that for "u", r, j and "u1" are obtained as recognition results.

The displayed content at this time is "kara" as a recognition result, and "shell j" as a conversion result.

is displayed in the sentence, and ``from r'' is displayed below it.

In this case, an erroneous recognition has occurred, so the user selects the next recognition candidate by instructing "RaJ" of the displayed "kara".As a result, the recognition result display changes to "kau".
At the same time, the conversion result display changes to "Buy J.

In this state, the recognition result is correct, but the conversion result shows homonyms, so the primary user selects the next conversion candidate as i!
translate. As a result, the recognition result display remains as "Kau", and the conversion result display changes to "R".

〔Effect of the invention〕

When using the handwritten character input device according to the method of the present invention,
Compared to the conventional method, the user can omit at least one step of operation for each word/phrase of each recognition conversion unit, so the operability is improved.

The efficiency of character input can be improved.
