Description

Character input device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a personal computer or word processor, and more particularly to a character input apparatus of a multilingual information processing apparatus for inputting characters of various countries.

In recent years, as borders disappear in the information society, so-called multi-ring girl processing, which deals with languages of various countries, is required. In the past, computer systems generally handle only one language, but according to the background described above, a system that simultaneously handles multiple languages has appeared.

In order to cope with such a situation, ISO defines ISO 10646, a character code system that includes all the coded characters of each country. In addition, a system was provided to handle languages. One example of such an operating system is described, for example, in the technical review of Tenno University of Foreign Studies, pp. 95-97.

In such a situation, a keyboard is first used as an input means of each language. A commonly used keyboard consists of only 100 keys for entering alphabets. To input Japanese characters, Chinese kanji, and Korean Hangul, the so-called FET (character input processor) is used to convert keystrokes and applications. It is supposed to input characters into the program. Another method is to use a handwritten character recognition to convert a handwritten character to a character code.

In keyboard input, you need to know the read aloud, which is the searcher of the character you want to input, but in the Suseo character input, you only need to know the Chinese characters. Japanese Patent Laid-Open No. 61-153788 describes a method of switching the character type of Kanji / Katakana / Hiragana in Japanese character recognition.

In recent years, as the exchange of East Asian kanji has become more active, the necessity of inputting Chinese and Korean characters is increasing at public offices and hotels. Even in Japan, opportunities for accessing information and entering text from these Chinese companies are increasing, especially in government offices and hotels, but in the present state, there is no simple way to enter Chinese characters from all these countries. On the contrary, Japanese and Korean inputs are required in China, and Japanese and Chinese inputs are required in Korea, respectively.

SUMMARY OF THE INVENTION The present invention has been made in view of such a point, and an object thereof is that a character input by a keyboard and a handwritten character can be input at the same time. It is to provide a character input device for input.

The handwriting input unit 102 is a transparent digitizer for detecting input coordinates by an electronic pen operated by a user for inputting handwritten characters, and the display unit 103 is a display screen of a display device such as a liquid crystal display. A handbook input unit 102 made of a tablet, a pen, or the like is superimposed on the device. The display unit 103 displays option designations, command buttons, and the like, which are in charge of an interface with the user as a result of the trajectory stroke or character recognition input by the user.

In this embodiment, the Japanese character recognition unit 105, the simplified character recognition unit 106, and the traditional character are recognized as a recognition unit that processes the stroke information of the characters inputted from the aquatic input unit 102 and converts the recognition result into a character code. The recognition unit 107 and the Korean recognition unit 108 are provided with recognition units for four languages, and the aquatic character recognition control unit 104 is selected from the recognition units 105 to 108 of these four languages by user's designation. One or more are selected, and the input stroke information recognized by this is converted into a character code and output.

The font generation unit 109 is recognized and converted by the recognition unit 105 to 108 of the characters of each country, such as to generate a Japanese font 110 for the character code recognized and converted by the Japanese recognition unit 105 Creates a character font of the corresponding country from the character code.

Each of the above processes is controlled by the central processing control unit 101, and the central processing control unit 101 displays the character port generated by the font generating unit 109 on the display unit 103, The character code obtained according to the instruction is sent out to the main work computer 1 via the character output control unit 114 and the communication line 115.

The configuration of the display integrated tablet 3 as described above can be implemented by a handwriting input device and software such as a pen computer or a personal digital assistant (PAD).

On the main work computer 1 side, the character input control unit 120 passes the character code sent from the tablet 3 to the application program 121 requesting the input of the character.

The main work computer 1 is realized by, for example, a personal computer and an application mounted thereon, and the communication line 4 is realized by seam communication or infrared communication.

FIG. 3 is a diagram showing one specific example of an image displayed on the display screen of the integrated display tablet 3 in FIG. 2, wherein 201 to 205 are language selection buttons, 206, ( 207 denotes a stroke drawing area, 208 denotes a clear button, 209 denotes a recognition start button, 210 denotes an input character display unit, 211 denotes a retract button, and 212 denotes a recognition candidate list area, and 213. Is a play button.

In the same drawing, the selection buttons 201, 202, 203, 204, and 205 designate a language type of a character to be input by aquatic character recognition, and select Japanese characters. Select button 201 for handwriting input, select button 202 for handwriting input of simplified Chinese characters, select button 203 for handwriting input of traditional Chinese characters, select handwriting for handwriting input of Korean characters The buttons 204 are operated respectively, and the selection button 205 is operated when the language type of each station of the character to be inputted is unknown. Here, not only "operation" but also the operation buttons are instructed with a pen or the like, and the same applies to other operation buttons.

Here, two stroke drawing areas 206 and 207 are provided on the display screen so that one character can be inputted to each of them. The clear button 208 is for canceling the texts being written to these stroke drawing areas 206 and 207. When the texts being drawn are wrong, the clear button 208 is operated to operate the texts. Only write strokes can be erased.

When the writing of the desired character is finished in any of the stroke drawing areas 206 and 207, the recognition character recognition control unit 104 in Fig. 1 operates the recognition start button 209 to coordinate the stroke of the character. The data is fetched through the central processing control unit 101, and the recognition unit according to any one of the selection buttons 201 to 205 of the recognition units 105 to 108 is operated to perform character recognition processing and recognition result. Perform the conversion to character code. This character code is converted to a character font as described above and supplied to the display unit 103, but the character of the recognition result is displayed on the input character temporary display unit 210 by this character font. By successively inputting characters one by one into the stroke drawing areas 206 and 207, and operating the recognition start button 209 for each character of input characters, the recognition results of those input characters are input characters in the order of input. The temporary display unit 210 is displayed.

In addition, by operating the recognition start button 209, the recognition operation of the handwritten characters drawn in the stroke drawing areas 206 and 207 is started. It is also possible to automatically start the recognition operation after a certain period of time, even if no operation is performed.

Some of the recognition results displayed on the input character display unit 210 may include recognition candidates having a second digit or less. Thus, when characters of the recognition result are displayed therein, the characters are indicated by a pen or the like, and if these characters have recognition candidates having the second digit or less, these recognition candidates are displayed in the recognition candidate list area 212. When one of the recognition candidates displayed in the recognition candidate list area 212 is instructed with a pen or the like, this indicated recognition candidate is replaced with the last arranged character at that time in the input character display unit 210. As a result, when the recognition result displayed on the input character display unit 210 is wrong, the recognition candidates other than this recognition result are displayed in the recognition candidate list area 212, and the correct recognition candidates are instructed therein. An accurate recognition result is obtained in the input character temporary display unit 210.

In addition, when the retreat button 211 is operated by specifying any character among the characters displayed on the input character temporary display section 210 with a pen or the like, this indicated character is erased. At this time, since the indicated character is indicated by a cursor (not shown), the position of the erased character is directly indicated by the cursor even when the character is erased. In this state, when a character is inputted to any one of the stroke drawing areas 206 and 207 and the recognition start button 209 is operated, the recognition result of the written input character is displayed on the input character display unit 210. It is inserted at the position indicated by the cursor. In this way, it is possible to correct a mistaken input character. When all the handwriting input of the characters is finished and the characters displayed on the input character display unit 210 are all correct, the character code of these characters is changed by the central processing control unit 101 in FIG. It is sent to the main work computer 1 side.

In addition, each operation button 201 to 205, 208, 211, and 213 are displayed using a graphical user interface.

Next, the operation of this embodiment will be described taking the sentence (string) shown in FIG. 4 as an example.

In addition, it is assumed here that the main work computer 1 can use the FEP to input Japanese on the keyboard 2. For example, the sentence to be input by the user is shown in Fig. 4A, wherein the strings 401 and 403 are Japanese, and the string 402 is a Chinese character which is not in Japanese. .

In the case of inputting such a sentence, the user first uses the FEP, and then inputs a character string 401 forming a part of Japanese on the keyboard 2. The character string 401 is displayed on the display screen 1a of the main work computer 1 at this time as shown in FIG. Next, the user executes input of the character string 402 constituting the Chinese part by the above operation on the display-integrated tablet 3. As a result, the character strings 401 and 402 are displayed on the display screen 1a of the main work computer 1 as shown in Fig. 4C. In addition, the user inputs a character string 403 constituting Japanese on the keyboard 2. At this time, on the display screen 1a of the main work computer 1, the character strings 401, 402, 403, that is, the whole sentence, are displayed as shown in Fig. 4D.

Next, the input operation of the Chinese character string 402 will be described with reference to FIG. If it is assumed that the language type of the character string 402 is Simplified Chinese, the selection button 202 is selected. If this is not known, the select button 205 is selected. In this example, the selection button 202 is selected. Then, the first character of the character string 402 is drawn in the stroke drawing area 206 by arithmetic. Thereby, the state shown to Fig.5 (a) is obtained.

When the drawing in the stroke drawing area 206 is finished, when a predetermined time has elapsed or when the user instructs the recognition start button 209, recognition of the handwritten characters drawn in the stroke drawing area 206 is started and FIG. As shown in (b), the character 300 of the recognition result is displayed on the input character display unit 210.

At this time, if the displayed character 300 is not the desired character, the character 300 is indicated by a pen (not shown) or the like in the recognition candidate list area 212 as shown in FIG. Candidate characters other than the recognition result are displayed. When the user selects a desired character among the characters displayed in the recognition candidate list area 212, the character 300 of the input character temporary display unit 210 is replaced with the selected character. In addition, when the desired character is not displayed in the recognition candidate list area 212, the retreat button 211 is instructed to delete the input character 300 and then characterize the character again.

Similarly, when the second character of the character string 402 shown in Fig. 4A is inputted, the character string 402 is recognized by the input character display unit 210 as shown in Fig. 5D. The result 301 is displayed. Thus, when the user instructs the dispensing button 213, the character code of the character string 301 displayed on the input character temporary display unit 210 is transmitted to the main work computer 1.

When the character code is received through the communication line 115 in the work computer 1, the character strings 401 and 403 inputted from the character string and the keyboard 2 are changed as shown in Fig. 4D. The display screen 1a of the work computer 1 is displayed.

Further, in the display state shown in Fig. 5D, it is found that the first character 300 of the character string 301 displayed on the display portion 210 is wrong, and the pen is corrected as described above. Etc., this character 300 is indicated, and the retraction button 213 is selected. As a result, the character 300 is erased, but a cursor (not shown) indicating the position of the erased character 300 is displayed. Thus, the character 300 is input again to the stroke drawing area 206 or 207 to be input again and processed to recognize the character 300 at the position designated by the cursor of the recognition result and the input character display unit 210. Is displayed. In this way, the character displayed on the input character display unit 210 can also be corrected at any time before selecting the dispensing button 213.

In the case where the selection button 205 is selected at the time of inputting the text string 402 of FIG. 4A, each character of the text string 402 in FIG. 1 is represented by the Japanese recognition unit 105 and the simplified character recognition unit 106. ), The traditional character recognition unit 107 and the Korean language recognition unit 108 recognize the recognition candidates. These recognition candidates are all displayed in the recognition candidate list area 212 as shown in FIG. 6, and at the same time, the most similar characters are displayed on the input character display unit 210. If a character that is more appropriate than the character displayed on the display unit 210 is present in the recognition candidate list area 212, the character is displayed on the input character display unit 210 by designating the character. It can be replaced with a written character.

In this case, in the recognition candidate list area 212, several characters having very similar character types may be displayed depending on the stroke information of the user. In such a case, the user is hesitant to select which character. Therefore, in the recognition candidate list area 212, language type information indicating which of the recognition units 105 to 108 is obtained for each character is displayed by the recognition processing of the aquatic input characters as shown in FIG. Do it. In Fig. 6, after each character displayed in the recognition candidate list area 212, a display such as (日) or (簡) is executed, and the character (Japanese) is represented by (日) and (簡). Make sure to mark each of them as Simplified Chinese.

In the above embodiment, the language input from the keyboard 2 to the main work computer 1 is Japanese, but Chinese or Korean may be used. This generally depends on the content of the document you are writing or the language of the user you are using.

In the above embodiment, the aquatic character recognition unit is provided on the display integrated tablet 3 side, but the main work computer 1 and the display integrated tablet 3 may be provided. It is considered in various ways as follows.
