Abstract

PURPOSE:To correct a reject character easily by a simple operation, to improve the workability, and to relieve the operators psychological load by executing the processings using a special code stored in a storing means. CONSTITUTION:A recognized code or the special code that indicates that the input was not recognized is stored in the storing part 8 through an input tablet 1. That means that the hand-written information inputted from the tablet 1 is transmitted to a recognizing part 7 through an input control circuit 6, and the part 7 outputs the special code indicating recognition-unable to the part 8 in case when the inputted character and/or signal is not recognizable. The part 8 stores this special code as well as the result by the function control of control circuits 10-14 and the current position of the cursor. Consequently, in case of correcting the reject character, searching for the special code from the present cursor position is made able. Therefore, the re-inputting and correction of the handwritten information can be executed easily, the workability is improved and the operators psychological load can be relieved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field J] The present invention relates to an information recognition device that recognizes information such as handwritten input characters, symbols, figures, etc.

[Summary of Disclosure] This specification and drawings are based on handwritten input characters, symbols,
In an information recognition device that recognizes information such as figures, when it is able to recognize handwritten information input from a handwritten input means that inputs handwritten information such as handwritten characters and symbols, it outputs a code corresponding to the handwritten information to the internal memory. If the handwritten information cannot be recognized, the handwritten information is corrected based on the above-mentioned specific code. The present invention discloses a technique for improving work efficiency by making it easier to correct rejected characters.

Note that this summary is provided solely for the purpose of quickly accessing the technical content of the present invention, and does not have any influence on the technical scope of the present invention or the interpretation of rights.

[Prior Art] In recent years, with the expansion of Japanese language information processing, there has been a demand for simple Japanese language input means. In particular, information recognition devices that recognize and input single handwritten characters in real time are attracting attention because they can be input simply by handwriting the characters.

Currently, various information recognition methods have been proposed in Japanese Patent Application Laid-Open No. 54-18833, etc., and it is reported that a recognition rate of 89% or more can be obtained in real time if the information is written carefully in kansho. However, this type of conventional device still has severe handwriting restrictions, and has not yet reached the stage where it can recognize cursive handwriting, abbreviations, individual-specific consecutive characters, etc. in real time, and achieve high recognition.

Therefore, characters written by a scribe (operator) are sometimes rejected without being recognized due to abbreviations or consecutive characters. However, if you carefully and carefully rewrite the characters in kaisho, most characters will often be recognized correctly.

[Problems to be Solved by the Invention] By the way, in such a conventional real-time character recognition type information recognition device, when a certain character cannot be recognized while inputting a document, ■ the unrecognized character is excluded. ■ A process was generally adopted in which a blank space or a "?" symbol was substituted and displayed in place of the unrecognized character. However, in the above-mentioned 0-term processing, even if you try to re-enter the rejected character after entering the text, it is extremely difficult to discover which character position in the text is the rejected character position. . In addition, in the above-mentioned 0-term processing, blanks and r? are substituted into the input text because the input characters cannot be recognized. '' symbol and a blank space or ``?'' entered as text, so it was extremely difficult to find the rejected character and re-enter it.

Figures 5 to 10 show specific examples of such processing in the conventional device. First, Figure 5 shows that "Japanese information With the expansion of processing, there is a need for a simple Japanese input method.'' When the character ``jo'' in the input text is not recognized for some reason and is removed, the internal memory It represents the character string on the RAM, and Figure 6 shows the display contents on the display screen DSP at that time.This example corresponds to the process in item 0 above, and after inputting one sentence, the display screen DSP
Unless you read back the text output very carefully, you will not know that a character has been rejected, and it will be difficult to correct the rejected character.

In addition, Figure 7 shows that when ``Mathematics Japanese Science Social Studies'' was input by hand on a tablet (not shown), for some reason the characters ``1 word'' in the input text were not recognized.
8 represents the character string on the internal memory RAM when a blank is substituted in the sentence instead of the character, and FIG. 8 shows the display contents of the display screen DSP at that time. However, "
The symbol "1" represents a blank space. This example corresponds to the process in item 0 above, and since the display screen cannot distinguish between the blank space when an input character cannot be recognized and the blank space in the text, it is difficult to find the reject character. Even if you find a blank space added to the text because a single character was not recognized, you will not be able to distinguish that space from the blank space in the text, and you will have to move the cursor again to re-enter the rejected character. Although it moves to the input location, it has the disadvantage of being a cumbersome task.

Furthermore, FIG. 9 shows that when a certain input character in an input sentence cannot be recognized, "?" is substituted for the unrecognized character.
” is added to the text in the internal memory RAM, and FIG. 10 shows the display screen DSP that displays the character string in the internal memory RAM. This example corresponds to the process in item 0 above. He entered the sentence ``Why? he asked.'' by hand, but for some reason the ``late'' handwriting could not be recognized, and a ``?'' symbol (question mark) was substituted for the ``?'' symbol (question mark). This is an example of substitution. In this example, too, the input character is unrecognized and is substituted with "
? " symbol and the "?" symbol in the text cannot be distinguished, so unless you reread the text very carefully, you will not be able to discover the characters that the device did not recognize. However, it is a cumbersome task to move the cursor to the re-input location for re-input.

In other words, in word processors (text editing devices) and the like that use conventional information recognition devices as input means, there is no simple means for correcting rejected characters, so scribes (operators) find it very troublesome. Another problem is that each character must be input while checking whether or not the handwritten character is recognized by the device, which reduces work efficiency and places an excessive psychological burden on the operator. There was a point.

An object of the present invention is to provide an information recognition device that eliminates the above-mentioned drawbacks, makes it possible to easily correct rejected characters with a simple operation, improves work efficiency, and reduces the psychological burden on the operator. Our goal is to provide the following.

[Means for Solving the Problems] In order to achieve the present object, the present invention provides handwritten characters and
A handwritten input means for inputting handwritten information such as symbols, and if the handwritten information input from the handwritten input means can be recognized, outputs a code corresponding to the handwritten information to an internal memory,
If the handwritten information cannot be recognized, the information recognition means substitutes and outputs a specific code indicating that the handwritten information could not be recognized into the internal memory, and the handwritten information can be easily corrected based on the specific code. It is characterized by what it did.

[Operation] According to the present invention, a specific code indicating that recognition could not be executed from the current cursor position toward the beginning or end of the sentence is written in the internal memory in accordance with a specific faction designation that instructs a search for a reject character. You can re-enter handwritten information by searching for it and moving the cursor to the specific code you searched for.

In this way, according to the present invention, the cursor can be automatically moved to a position where information could not be recognized and handwritten input can be re-inputted, making it easy to correct rejected characters and improving work efficiency.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the basic configuration of an apparatus according to an embodiment of the present invention, where a is an input means for inputting handwritten information, b is an information recognition means for recognizing input handwritten information, and C is recognition by the information recognition means. d is a correction means that operates according to a specific function designation; e is a display means for displaying the contents of the internal memory C and a cursor. . The correction means e searches for the above-mentioned specific code in the internal memory C in accordance with the specification of a specific func code, moves the cursor, and makes it possible to re-input the handwritten information.

FIG. 2 shows a circuit configuration of an embodiment of the present invention.

Here, 1 is an input doublet for inputting handwritten information,
Reference numeral 2 denotes an input pen used as a writing instrument for handwriting input into the tablet. 3 is an entry frame with a matrix arrangement t indicating the range in which handwritten information such as letters and symbols is to be entered in the doublet l;
is a function specification area for specifying various functions, and 5 is a reject character search key (area) for instructing to search for reject characters. In order to enter the area allocated to each function pen? Just touch it.

6 is an input control circuit for inputting the position coordinates of the pen 2 and the up/down information of the pen output from the input doublet 1; 7 is a recognition section; 8 is a storage section; 9 is a function control circuit. The input control circuit 6 sends information regarding strokes such as symbols written in the writing frame 3 to the recognition section 7 based on information from the input doublet 1, and sends information regarding function designation to the function control circuit 9. The recognition unit 7 recognizes information such as character symbols written in the writing frame 3 based on information regarding strokes from the input control circuit 6, converts it into a corresponding character/symbol code, and sends it to the storage unit 8. At this time, if the recognition unit 7 cannot recognize the input characters, symbols, etc., it sends a special code indicating that the input characters/symbols could not be recognized to the storage unit 8. The storage unit 8 stores information recognition results obtained from the recognition unit 7, results of function control of control circuits 10 to 14 for each function, which will be described later, and the current cursor position.

The above-mentioned function control circuit 9 obtains information regarding function designation from the input control circuit 6, determines which function (IN function) the information is designated, and controls the control circuits 10 to 14 of each designated function.
send a signal to. Here, 10 is a cursor control circuit that controls the cursor position, 11 is an insertion control circuit that controls character insertion, 12 is a deletion control circuit that controls character deletion, 13 is a replacement control circuit that controls input sentence replacement, and 14 are the injection control circuits described later, and these control circuits 10 to 10 are
14 each receives a signal from the function control circuit 9 and performs a corresponding function control on the input sentence stored in the storage section 8 described above.

The rejection control circuit 14 includes a storage section 8 which is an internal memory.
For the character string stored in the cursor position, the input characters are sequentially moved from the current cursor position to the beginning (or end) of the sentence, or from the beginning of the sentence where the cursor is located to the end of the sentence. The special code represented is searched for, the location of the found special code is sent to the cursor control circuit 10, and insertion, deletion, and replacement commands are sent to the insertion control circuit 11. Deletion control circuit 12. It is sent to the replacement control circuit 13.

15 is a display screen using CRT, liquid crystal, etc.
This is a display circuit that accommodates the DSP, and displays the text currently being input stored in the storage unit 8 and the cursor in real time.

FIG. 3 shows a display example of the embodiment of the present invention on the display screen DSP of the display circuit 15 in FIG. 2.The display example in FIG. This is a case where the user inputs ``I am requested.'' into the character frame 3 of the input doublet 1 using an input pen, but the handwritten character ``jo'' in this sentence is not recognized for some reason. The underline C next to the full stop symbol "," on the display screen DSP in this figure is a cursor.0 In this example, if an input character or symbol is not recognized, a question mark "?" is displayed on the display screen DSP. It is displayed in the position of the character/symbol that was not present, but in storage section 8 of the internal memory, the code for the question mark "?" has not been input, but a specific code that indicates that it is a reject character has been input. It is assumed that there is

The flowchart of FIG. 4 shows an example of the operator's operation procedure from the display state of FIG. 3. First, in the state of FIG. (Step S
1) Then, the funky character information of this search key 5 is sent to the reject character search control circuit 14 via the input control circuit 6 and the funky character control circuit 9, and is then sent forward from the current cursor position to the memory section. 8, and it is determined from the specific code that the character immediately before "r news" has been rejected, and the cursor C is moved to the display position of the question mark "?" in front of "r news". The operator confirms that the cursor C has moved to the display position of "?" (step S2), and touches the single character replacement key in the function designation area 4 with the pen 2 (step S3).
), then this funxy, n information is sent to the replacement control circuit 13 via the funxy stamp control circuit 9, and the single character replacement mode is entered.Next, the operator carefully writes the character "jo" again with the pen 2. Write down the measures (Step S0
．． Then, the handwritten character information for ``jo'' is sent to the recognition unit 7 via the input control circuit 6, where it is correctly recognized, and under the control of the replacement control circuit 13, the zero-order character information is replaced with a specific code indicating the paste in the storage unit 8. Then, the operator uses the display screen DSP of the display circuit 15 to confirm that the reject code "?" is "information".
After confirming that it has been replaced with the character (step S5),
The cursor C is moved to the end of the sentence currently displayed on the display screen DSP (step S8), and handwritten input is resumed (step S7).

Furthermore, in the above embodiment, by touching the reject character search key 5 and 2, the reject character "?" is displayed.
However, by touching the reject character search key 5 with the pen 2, the cursor is moved to the reject character, and the mode is automatically set to single character replacement mode, or the rejected character is deleted. or, equivalently, enter single-character replace mode and type a character to enter insert mode; in this case, the single-character replace key is not needed. Become.

In addition, the reject character search control circuit searches for a forward edge reject character from the current cursor position toward the beginning of the sentence, and if there is no reject character before the beginning of the sentence, the reject character search control circuit automatically restarts the search for reject characters from the end of the sentence. 14, and if there are no reject characters even after searching the entire text, a message indicating that there are no reject characters is displayed and the state returns to the state before the pen touch on the reject character search key 5. It is also possible to control the reject character search control circuit 14 to return the cursor again.

It is also possible to search for reject characters backwards from the current cursor position, or to search for reject characters by first moving the cursor to the beginning of the sentence. In this case, once the rejected character is replaced with a correct character, the search for the rejected character can be restarted, and if there is no rejected character, it is also possible to automatically move the cursor to its original position.

In addition, in the display example shown in Figure 3, if a written character cannot be recognized, a "?" symbol is output to the display screen DSP.
Instead of simply displaying "?", you can change the brightness of the display or invert it at the same time.Furthermore, if the handwritten characters cannot be recognized, a buzzer will sound at the same time as "?" is displayed. You may also warn the scribe,
The symbol that displays a reject character is not limited to "?"
Specific display symbols that are not normally used in sentences, such as "■"
Or "■" is fine.

[Effects of the Invention] As described in section H below, according to the present invention, it becomes possible to easily correct rejected characters, and the work attendance rate can be improved.
