DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a character input device.

[0002]

2. Description of the Related Art In recent years, with the borderlessness of the information society, in the field of information processing, so-called multilingual processing, which handles words of a plurality of countries, is required. conventionally,
While most systems handle languages of one country at the same time on one computer system, the background described above has led to the emergence of systems that handle languages of multiple countries simultaneously. To cope with such a situation, I
SO defines a character code system ISO10646 that includes all coded characters for each country.
In addition, systems have been provided that can handle the language of multiple countries. An example of such an operating system is shown on pages 95 to 97 of "Dengan University of Foreign Studies" published by Gijutsu Hyoronsha in 1993.

[0003] However, in the current system of each country, even if the operating system can handle the above-mentioned integrated character code, there are many application programs that operate on it, which can still process only the character code system unique to each country. On the other hand, the function of inputting characters to each application uses the function of the operating system, and a character input program unique to each country can be automatically switched and input. In this case, there is a problem in usability that the input operation is different for each language. In order to solve this problem, it is conceivable to prepare an integrated multilingual character input program capable of inputting all characters. As such a character input unit, an input by handwritten character recognition that can freely input strokes of all characters, or a character conversion input unit that converts a character input from a keyboard into another character can be used.

[0004] However, these integrated character input means conventionally perform input processing independently of an application. For this reason, if the application relies on the character code system of a specific country and outputs a character code that cannot be processed by the application using a multilingual character input program, the application sets the character code to "?" In such a case, the character was replaced with an appropriate character and processed, or in the worst case, the application performed abnormal processing and stopped. For the user, there is a problem that whether or not the character input by the character input means can be processed by the application is not known until the character is actually input to the application.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a multilingual character input system capable of inputting multilingual characters so that only characters of a character code system corresponding to an application are input, thereby improving user convenience. An object of the present invention is to provide an improved character input device.

[0006]

[Means for Solving the Problems] To solve the problems,
The character input device of the present invention is provided with a character code system notifying unit for receiving a character code system corresponding to the application, and a character code inspection unit for checking a character code of a conversion result of the input data, and a dictionary search unit in the conversion unit. Judge whether the character code of the conversion result can be handled by the application, add only the conversion result that can be handled to the candidate, and do not add the conversion result that can not be handled to the candidate, so that the user does not get lost when selecting the candidate Enabled to input.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a character input device according to the present invention. Reference numeral 101 denotes an application program, such as a word processor or a worksheet, to which characters are to be input. An operating system 102 executes an application program. The operating system 102 controls the execution of the application, controls input / output devices, and comprehensively controls the conversion unit of the present invention. The input unit 103 is a device such as a keyboard capable of inputting a pin sound or a Roman character (English character), or an input device such as a tablet capable of inputting handwritten characters. A display device 104 displays information necessary for an interface with a user, such as a request for an application program and an intermediate state of a conversion unit.

Reference numeral 105 denotes a conversion means, which is a dictionary search means 1
07, the user is presented with a plurality of search results output by the dictionary search means, and the final character string is delivered to the application through the operating system according to the user's selection. Reference numeral 107 denotes a dictionary search unit that searches the dictionary 109 according to a character string or stroke information input from the input unit 104. The dictionary 109 is input means 103 in the case of keyboard input.
In the case of handwriting input, the input means 1 stores a character string corresponding to the character string input from
The character code corresponding to the vector data that matches the stroke information input from 03 is stored. 1
Reference numeral 06 denotes a character code system notifying unit that acquires information on a character code system that can be received by the application from the operating system and holds the information. In recent years, operating systems are able to acquire information on the character code system of an application from the attribute information of the application program at the time of startup. The character code system notifying unit 106 calls an appropriate function of the operating system, and acquires information on a character code system supported by the application at the start of character input. 108 obtains the character code system stored in the character code notifying means, and checks whether the character string searched by the dictionary search means does not include a character code that cannot be processed by the application such as display. Character code inspection means.

The present invention provides, for example, a CPU and a memory;
It can be configured by a general personal computer having an external storage device and an input / output device and control software. Alternatively, the present invention can be implemented as a dedicated terminal device incorporating a control program.

Hereinafter, the operation of the character input device of the present invention will be described. FIG. 2 is a character code table for realizing the character code checking means of the present invention. The character code table stores the character codes of the corresponding countries for each of the above-described ISO10646 character codes. In FIG. 2, GB2312 which is a standard character code of China, BIG-5 which is a character code of Taiwan, and JI which is a standard character code of Japan
S, KS code which is a Korean character code is shown.
In addition, a column of a character code system of each country can be provided as needed. When a character is not included in the character code system of a certain country, “0000” indicating an invalid character code is stored. For example, the character indicated by 201 exists only in the GB code.

In the case of keyboard input, when a user inputs a character string to be converted and gives a conversion instruction, dictionary search means 10
7 searches the dictionary 109 using the input character string as a search element and converts it into a kanji character string.

FIG. 3 shows an example of a dictionary for keyboard input.
Shown in The dictionary contains a Roman character string 301 as a search element.
And the corresponding word notation 302 and part of speech 303. The word notation is stored in the character code of ISO10646, and characters of all countries can be stored. For example, 304 stores “Chinese” for the Japanese reading “chuuka (TYUUKA)”, and 305 stores the same as “Chinese” for Japanese reading “ZHONGHUA”. The character corresponding to “Hana” in which the notation of the meaning is stored is a character that exists only in the GB code, as indicated by 201 in FIG. 3
06 is a character code existing in JIS or BIG-5 for the same “ZHONGHUA”.

Next, the conversion result, that is, the dictionary search result is
It is sent to the character code inspection means 108. The character code checking means is notified from the application through the operating system, and the character code system notifying means 106
It is determined based on the character code system held in the application whether the character string of the dictionary search result can be processed by the application. That is, the character string of the search result is examined one character at a time, and the notified character code column of the corresponding character code is referred to. If the character code is "000
If it is "0", the dictionary search result is discarded. If all the characters can be converted to a value other than "0000", the characters are transferred from the dictionary search unit to the conversion unit, and finally passed to the application after selection by the user, as those which can be processed by the application. For example, when the application supports only the JIS code system and inputs "ZHONGHUA" from the keyboard and issues a conversion instruction, 305 and 306 are searched from the dictionary, but 306 is not supported by the JIS code system. Since characters are included, 306 is not added to the conversion result. On the other hand, since all 306 are composed of characters included in the JIS code system, they are added to the conversion result. When the application supports the GB code, since both 305 and 306 are composed of characters included in the GB code, both are added to the conversion result.

As described above, after obtaining the result checked by the character code checking means, the conversion means displays the conversion result to the user and waits for the user to give an instruction to select and confirm the conversion result. The character string selected and confirmed by the user is transferred to the application, but the characters passed at this time are only characters that can be processed by the application, so characters cannot be displayed or the application performs abnormal processing. Can be prevented.

Without the processing of the present invention, if the application supports only the JIS code system in the same example, for example, if the user's native language is Chinese, “TY
It is expected that "ZHONGHUA" will be input without inputting "UUKA". In such a case, if the conversion results of 305 and 306 are displayed, and the user erroneously selects and confirms 306 and outputs the result to the application, the application cannot process the character string of 306 and the character string such as "?" Instead, it will be displayed in characters.

According to the present embodiment, only characters that can be processed by the application can be input to the user, so that the user does not get lost in selecting a conversion result when inputting characters.

When the input means is a handwritten character input, the search element of the dictionary 109 can be implemented in the same way as the case of the keyboard input by using the vector data of the character and the notation as the character of the recognition result. is there.

In the embodiment, the character code stored in the dictionary is ISO10646. However, when the final conversion result is output, it may be converted into the character code system of the output destination application and output. Alternatively, this processing is unnecessary when combined with an operating system having such a function.

[0020]

According to the present invention, in a character input device capable of inputting a multilingual language, only a character code system character that can be handled by an application is used. By not adding only conversion results to conversion result candidates and conversion results that cannot be handled to candidates, it is possible for the user to input without hesitation when selecting candidates.
