SOLUTION: This system is equipped with a pronunciation input part 1 which inputs the pronunciation of a reading of KANJI, a pronunciation-KANA conversion part 2 which converts the pronunciation of the reading of KANJI inputted by the pronunciation input part into KANA, a KANA-KANJI conversion part 3 which converts the KANA sent out of the pronunciation-KANA conversion part into one or more KANJI candidates, a writing order input part 4 which inputs the pattern of the 1st writing order of the description of KANJI, a writing order recognition part 5 which discriminates whether the pattern of the 1st writing order is at the upper part or left part of a description area, a KANJI selection part 6 which extracts a KANJI candidate having the matching pattern of the 1st writing order and the matching position of the description area out of KANJI candidates sent out of the KANA-KANJI conversion part, and a KANJI display part 7 which displays the KANJI candidates sent out of the KANJI selection part and makes a user to determine one of them as desired KANJI.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kanji input method, a kanji input method, a program recording medium, and more particularly to a kanji input method, a method, and a program recording for selecting and displaying candidate kanji of the same phonetic character based on the pronunciation and writing order of kanji. Media related.

[0002]

2. Description of the Related Art In countries dealing with kanji, kanji is generally input using an English typewriter keyboard. Kanji is expressed by a certain rule, and a key according to the rule is input to enable kanji processing. This series of functions is called FEP (Front-End Pr
ocessor) function.

[0003] From the user's point of view, the speed and convenience of FEP are always conflicting. A fast input method cannot usually be improved without a certain amount of training. Convenient input means does not require special training, but impairs the speed of input. With the spread of personal computers, convenient input methods that can be realized without training are now mainstream.

[0004] Among them, the most common input method is pronunciation input. In the case of Japanese, one pronunciation corresponds to a large number of kanji (or a plurality of words in one pronunciation conversion unit). Therefore, when converting kanji with pronunciation input,
You have to choose from multiple candidates. The operation of this selection greatly affects the speed of input.

[0005]

As described above, in the conventional kanji input method, a user spends time in an operation for selecting a desired one from a large number of candidate kanji of the same phonetic character. . To shorten this time as much as possible,
Various learning functions have been added to P so that kanji that are statistically frequently used or frequently used in the document being input can be displayed and selected in an earlier order, but this function is always shown. It cannot be done. That is, in order to fully exert the learning function, it is necessary to use (experience) as such.

SUMMARY OF THE INVENTION An object of the present invention is to provide a conventional kana-kanji conversion function to significantly reduce the number of candidate kanji by designating the writing order of kanji to be input. An object of the present invention is to provide a kanji input method, a method, and a program recording medium that reduce the number of kanji and facilitate selection of kanji.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, the kanji input method according to the present invention
A pronunciation input unit 1 for taking a kanji reading utterance, a pronunciation-kana conversion unit 2 for converting the kanji reading utterance fetched by the pronunciation input unit to kana, and whether the pronunciation-kana conversion unit sends out. Kana-kanji conversion unit 3 for converting kana into one or more candidate kanji
And a writing order input unit 4 for inputting a pattern of the first writing order of kanji notation, and a writing order for identifying whether the pattern of the first writing order is at the top or left of the kanji notation area. A recognition unit 5, a kanji selection unit 6 for extracting, from among the candidate kanji sent by the kana-kanji conversion unit, one in which the pattern in the first writing order and the position of the writing area match, and the kanji selection unit A kanji display section 7 for displaying candidate kanji to be transmitted and determining one of them as a desired kanji.

FIG. 2 is an explanatory diagram showing a sound input process in the kanji input method. In the figure, in the user's input (S11), the utterance of the kanji reading user can be input, but usually the kanji pronunciation is input from the keyboard and converted to kana (S12).

Subsequently, according to the user's conversion request (S13), the above-mentioned kana is scanned and analyzed in units of conversion (S1).
4). Then, kanji is converted for each conversion unit (S15), candidate kanji that can be converted are displayed (S16), and the user is prompted for confirmation or reconversion (S17). If all of the pronunciations are confirmed (including no conversion), the conversion is completed (S
18).

In the above-mentioned pronunciation input processing, it is possible to speed up and simplify kanji input by utilizing the learning function described above.

According to the present invention, it is possible to greatly narrow down the number of candidate kanji characters by inputting not only the above-mentioned pronunciation input but also information on the kanji writing order. In addition,
The stroke order information does not need to be complete, and only the first stroke is focused on here.

Although the stroke order, the number of strokes, and the type of kanji can be enormous when classified finely, the initial stroke order is actually four types of “-”, “|”, “ヽ”, and “丿”. Can be roughly classified. Furthermore, the starting position of the first stroke is "from left" and "from above"
If you classify into, it will be classified into eight types
Theoretically, the number of candidate kanji can be reduced to one-eighth. If this classification is made finer, the range to be narrowed down can be further restricted.

For example, when the pronunciation of "Koji" is input in Japanese and converted into kanji, a normal FEP displays about 70 candidates. Normally, a page is divided into about 10 words, so that an average of about 4 page switching operations and a process of visually identifying characters in the page are required for selection. In reality, the sort order is different for each machine and each user depending on the learning function, so searching for a page candidate is a very careful operation.

If the above-mentioned stroke order input is used in combination to achieve the ideal efficiency, the word to be searched will appear on the first page by reducing 70 words to 1/8.

For example, in order to select the kanji "consequent" from the pronunciation of "kouji", enter "kouji" and enter "from left".
If the FEP is given information that is sorted by “丿”, “rear”, “public notice”, “good”, “kouji”, “kouji”, “koji”, “koji” Since only seven “favorite” items can be displayed preferentially (on the first page), the efficiency of selection and input can be greatly improved.

FIG. 3 is an explanatory diagram showing a process of inputting the stroke order in the above-mentioned kanji input method. First, a list of candidate kanji after conversion by pronunciation input is acquired (S21).

Next, information for designating one of the eight types of writing order is input (S22). This writing order input method will be described later.

Subsequently, the candidate kanji is sorted based on the input stroke order information, and the corresponding candidate kanji is displayed to prompt the user to select and confirm (S23, S24, S25).

FIG. 4 is an explanatory diagram showing a configuration example of the writing order input section 4. This figure shows a pad for inputting the writing order with a finger, and detects that the finger moves on the pad by light or static electricity.

In the figure, an upper space (41): when the first image starts within this range, it is recognized as starting from above.

Left space (42): If the first image starts within this range, it is recognized as starting from the left.

Fuzzy space (43): Although the first image is not usually in this range, the recognition degree is further increased by using the stop position of the first image together.

The writing order recognition unit 5 calculates the start position and the end position of the first stroke using coordinate values, and calculates "-", "│", "ヽ",
It is divided into four types of “丿”. While the Kanji conversion software (FEP) is displaying the list, the corresponding signal is read and the sort of the list is switched in real time.

It is desirable that the above-mentioned writing order input section is provided, for example, at an extended position of the keyboard so that the user can touch the area within a small range of finger movement.

Further, the same function as described above can be realized by using a conventional device. For example, a pad or a pointing device attached to a personal computer or the like can be used. Furthermore, a function key of a personal computer can be used.

The kanji input method according to the present invention operates by executing a program stored in a main memory (not shown) of the processing unit. This program is usually stored in a secondary storage such as a hard disk, and is loaded into the main storage and executed when the system is operating.

[0035]

As described in detail above, according to the present invention, since the writing order of kanji is specified in addition to the kana-kanji conversion function, the number of candidate kanji at the time of conversion can be greatly reduced. it can. Therefore, there is an effect that the input speed of kanji data can be remarkably improved.
