DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen input computer, a handwritten character input device used for a pen-operated portable information terminal device and the like, and a recording medium in which a computer program for handwritten character input is recorded. More particularly, the present invention relates to a handwritten character input device having an improved operability by adding a display function of an input reaction character image responding to an aspect of a handwritten character, and a recording medium on which a computer program for inputting handwritten characters is recorded.

[0002]

2. Description of the Related Art Conventional character input devices include a device for inputting from a keyboard and an OCR (Optical Character Reader).
As described above, there is a type in which handwritten characters written on a specific sheet are optically read and input, and a type in which handwritten characters are directly input on a character input screen or the like with an electronic pen or the like.

In a character input device using a keyboard, when inputting a kana-kanji character like a normal word processor, a hiragana input or a roman character is input from a keyboard, the kana-kanji conversion is performed, and a corresponding character is determined and input.

[0004] OCR optically reads characters handwritten on paper or the like, captures them as two-dimensional image information,
By comparing the two-dimensional image with a registered standard two-dimensional image, a corresponding character is determined and input.

[0005] Handwritten character input by an electronic pen or the like is performed by handwriting input with an electronic pen or the like directly on a tablet-type coordinate input device or the like, and based on stroke information as time-series data of each pen point (coordinate point) of the input character. Perform pattern matching (online recognition) to recognize characters. Besides that,
In some cases, recognition is performed only with a two-dimensional image without using stroke information (offline recognition), or both online recognition and offline recognition are used.

[0006] Normally, when used in business or the like, input from a keyboard that allows high-speed input is the most common. Handwritten character input devices are not suitable for high-speed input, require a large amount of character data for character determination, require a large amount of calculation for recognition, and require long time for recognition. Was not widely used due to the habit of individuals and mistakes in stroke order, and the recognition rate was lower than that of keyboard input.

In recent years, the performance of CPUs of computers, the integration of memories, and the cost of them have been rapidly increasing, and computers with high performance and large-capacity memory, which are small in size, have become widespread. Mobile computers are also evolving rapidly. Above all, regarding a small mobile computer, even if a keyboard is attached as an input device, the keyboard becomes too small and it is difficult to input, so
The number of inputting characters by handwriting has increased.

[0008]

With the rapid spread of computers, more and more people have access to computers. However, for those who are not familiar with keyboards, such as beginners and children of personal computers and word processors. Until you get used to the keyboard, it is difficult to find out where the character you want to enter is on the keyboard, hit the keyboard several times in Kana input or Romaji input to enter one character kanji, it is necessary to convert kana kanji,
Many people are not accustomed to keyboard input and hate computers. Even for such people, if you do not need to search for the character you want to enter from the keyboard or input with troublesome kanji conversion, enter as if you are writing characters normally, and if necessary, select characters from character candidates. Input is easy because only selection is required.

In order to further spread the use of computers, there is a demand for technical means that increase the interest and interest of beginners in handwritten character input.

[0033]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The principle of the present invention and the flow of basic operations will be described with reference to the basic configuration diagram of the present invention shown in FIG. 1 and the flowchart shown in FIG. 1 and 2 showing the basic principle and basic operation flow of the present invention are based on claim 2,
Claim 2 shows claim 1 more specifically.

First, characters are input by handwriting from the character input unit 1 with an electronic pen or the like, and character characteristic information of the input handwritten characters is obtained and sent to the character recognition unit 2 (step S).
1). How the character feature information is obtained depends on the character recognition method. If the character recognition method is online processing, it is obtained as time-series stroke information, and if it is offline processing, it is obtained as two-dimensional image data. I do. Next, the character recognizing unit 2 compares and searches a character matching the character characteristic information of the handwritten character with the character characteristic information of the character registered in the character recognition dictionary 2-1 (step S2). Is transferred to the character display section 3, and the corresponding character is displayed (step S3). Character recognition methods include an offline recognition method using two-dimensional image information of characters as character feature information, an online recognition method using stroke information that is time-series information of characters, or both. There is a hybrid type recognition method for performing the recognition of any of these. Here, any recognition method may be used. Also, when the recognized character is different from the character to be input at the time of character recognition, the method of displaying character candidates one after another or displaying a list so that the character can be selected is the same as the conventional method. In the embodiment of the present invention, the description of the character candidate display / selection function will be omitted. The parts so far are the same as those of the conventional handwriting input device.

The present invention is different from the conventional example in the following points.

When the character is analyzed by the character recognizing unit 2, character information for determining an input reaction character image to be displayed is extracted and sent to the character code determining unit 4 (step S4). The character information is information such as beauty or difficulty of the character required from the input character. The character code determination unit 4 determines the character code of the input reaction character image to be displayed from the character code table 4-1 based on the character information from the character recognition unit 2,
It is sent to the character display section 5 (step S5). The character display unit 5 searches the character storage unit 5-1 based on the character code, acquires the data of the input response character image to be displayed, and displays the input response character image (step S6). The character storage unit 5-1 stores, for example, input reaction character images of a plurality of faces having different expressions.

The data of the input reaction character image is not limited to a still image, but may be a moving image. here,
Although only the input response character image is displayed based on the character information, not only the input response character image but also
It is more effective to display the message in text or output it by voice.

Although handwritten character input is uninteresting for beginners, especially children, it is not desirable to use it if it is not necessary. However, according to the present invention, an input response character in response to input characters is provided. Since an image is displayed and evaluated by a message, the user's willingness to input a handwritten character is promoted, and an effect of accustoming to an information device having a handwritten character input function occurs.

[0039]

Embodiment 1 An example of changing an input response character image to be displayed according to the beauty of an input handwritten character will be described with reference to FIG.

The character input unit 1 according to the present invention inputs handwritten characters from handwritten character input means such as an electronic pen, and when input characters are recognized by off-line processing, two-dimensional image information is recognized. Is performed, the data is captured as data in the form of time-series stroke information.
The character recognition unit 2 compares the character with the character feature information registered in the character recognition dictionary 2-1 to recognize which character is the input character, and determines the character code of the corresponding character. The character recognition dictionary 2-1 is composed of character codes and character feature information as shown in FIG. 4A, and the determined character codes are sent to the character display unit 3 and displayed on the screen. The character display area may be displayed in the handwritten character input area on the screen, or may be displayed in another area on the screen.

The character recognizing section 2 includes a score calculating section 6 for calculating a Euclidean distance between a two-dimensional image of a handwritten input character and a two-dimensional image registered in a character recognition dictionary. Ask. When using the online recognition method as the character recognition method, the stroke information is
Once it is converted to a two-dimensional image, it is calculated. By calculating the Euclidean distance, the shorter the Euclidean distance is, the closer to the standard character image registered in the character recognition dictionary, and it is determined that the character is beautiful. Conversely, the longer the Euclidean distance is, the less beautiful the character is. Thresholds for determining whether the input characters are beautiful or not beautiful are determined in advance, are stored in the character code table for each character code, and are based on the character codes determined by the thresholds. The user selects from the images of the input reaction character images stored in the character storage unit 5-1 to change the expression of the input reaction character image to be displayed.

Since the character recognition unit 2 recognizes a character using a two-dimensional image or stroke information of the character when recognizing the character, the score calculation unit is preferably provided in the character recognition unit 2. May be independent or placed in the character code determination unit 4.

The score calculated by the score calculation section 6 is sent to the character code determination section 4, and the character code determination section 4 converts the input response character image table 4-
Determine the character code corresponding to the score from 1;
The character code is sent to the character display unit 5. As shown in FIG. 5A, the contents of the input response character image table are, in the present embodiment, the scores are positive numbers, and the scores 1 to n are the ranges of the scores of the respective input response character images. Represents The character display unit 5 acquires an input response character image, an input response character image, and a message corresponding to the character code from the character storage unit 5-1, and displays the input response character image,
The message is sent to the message output unit 7. In the present embodiment, it is assumed that a message is output. Therefore, the character storage unit 5-1 has a structure as shown in FIG. 5 (g). The structure is as follows. The message is text data when displayed in text, voice data of any format when output by voice, and text data and voice data when both text and voice are output. Consists of The input reaction character image and the message are paired. Here, when a plurality of input response character images share the same message, the message in the character storage unit 5-1 is used as a message code, the message is stored as a separate table, and the message output unit uses the message code based on the message code. A message may be retrieved from the message table and output.

The message output unit 7 having received the message code obtains the corresponding message from the message table 7-2 and outputs the message. The output of the message may be displayed on the screen in the form of text, may be output from a speaker as audio, or both. To output by voice,
The message may be registered as voice data, or may be registered as text, and may be used as an input to perform voice synthesis and output. The same applies to the message output unit 7 of the other embodiments.

The input response character image and the corresponding message displayed here display an input response character image with a delightful expression when the input characters are beautiful, and give praise such as "You can write beautifully!" Outputs a message, and if the input character is dirty, displays an input response character image with a sad expression, and outputs a message such as "Please write more carefully!"
According to the beauty of the input character, an input response character image with a different expression or a different message is output.

The input response character image and message are
Although the characters are erased and displayed for each character, the same input response character image may be displayed.
The previously displayed character code may be stored in the storage device, and if the character code is the same as the previous character code, the character code may not be deleted and displayed.

Also, a score of a predetermined number of characters in the past is calculated as follows:
The score is stored in the score calculation unit 6, and according to the degree of the change in the score, "I am getting better and better!"
Alternatively, a message may be output by catching a change in the input character such as "how to write is getting rougher!" In addition, a function may be provided such that a model character is superimposed on a handwritten input character so that a deviation of the character can be confirmed so that the quality of the handwritten character can be determined at a glance. .

According to this embodiment, if the handwritten input character is beautiful, the input reaction character image is praised,
If you write characters roughly, the input reaction character image will take care of you, so you will be more motivated to write characters more carefully and beautifully, and you will acquire beautiful characters.

[0049]

Embodiment 2 Next, an embodiment for displaying an input reaction character image according to the difficulty level of an input handwritten character will be described with reference to FIG. The same portions as those in the first embodiment are denoted by the same reference numerals, and the description will be appropriately omitted.

In the present embodiment, as shown in FIG. 4B, the contents of the character recognition dictionary 2-1 are stored in each character data of the character recognition dictionary 2-1 of the first embodiment. Of difficulty. In addition, the character recognizing unit 2 passes the difficulty level of the recognized character to the character code determining unit 4 as data for determining the character code.

The character code determination section 4 selects a character code based on the difficulty such as the number of strokes passed from the character recognition section. The character code is determined based on the difficulty level. For example, when the difficulty level is evaluated on a 10-point scale, if the difficulty level is 3 or less, it is considered that the character is easy to input, and if the difficulty level is 4 or more, 7 or less. It is assumed that the character of the character has been input, and when the difficulty level is 8 or more, it is considered that a difficult character has been input, and an input response character image and a message corresponding to the difficulty level are displayed and output. When a difficult character is input, an input reaction character image of a surprised expression appears, and a message such as "I know a difficult character!" Applying this to the character code table of the present embodiment in FIG. 5B, the difficulty level is a positive integer of three levels, and the difficulty level is 1 = 3 and the difficulty level is 2 =
7, difficulty level 3 = 10. In this case, it is determined that 3 or less are easy characters, 4 to 7 are characters of normal difficulty, and 8 to 10 are difficult characters. Only when a difficult character is input, an input response character image and a message may be output.

The input response character image and the message
It is erased and displayed for each character. However, since it is not possible to judge the difficulty until a simple character such as a hiragana, a number, or an alphabet is input, the input response character image is displayed only when a difficult character is input. When displaying, prepare a blank input response character image and a blank message to erase the character display area, and display a blank input response character image and a blank message unless you enter difficult characters By doing so, it is preferable to clear the character display area and the message display area.

The method of setting the degree of difficulty is free. For example, the degree of difficulty may be set simply by the number of strokes of a character, or may be set by combining a common kanji and the number of strokes. The two levels and the number of strokes may be set in combination.

When the present embodiment is used, for example, for practicing kanji for a child, the reading of the kanji to be input is displayed, and the kanji is input, the difficulty level of the character recognition dictionary is changed according to the grade of the child. This allows you to make settings according to your age.Every time you enter a kanji character, you can determine whether not only the kanji character but also the sentence kana is correct and whether the stroke order is correct. Because the character image evaluates, you can also enjoy uninteresting kanji practice and learn the correct kanji.

[0055]

Embodiment 3 Next, an embodiment for displaying an input response character image in accordance with the total number of input handwritten characters will be described. In the configuration diagram of the present embodiment, in FIG. 3, which is a configuration diagram of the first embodiment, the score calculation unit 6 is replaced with a total calculation unit, and the score passed from the score calculation unit 6 to the character code determination unit 4 changes to a total. Therefore, description will be made with reference to FIG. A description of the same parts as those in the first embodiment will be appropriately omitted.

In this embodiment, the total calculator calculates and stores the total of the input characters each time the character is recognized by the character recognition unit 2 and sends the calculated total to the character code determination unit 4. The initial value of the total of the total calculator is zero, and the timing of the initialization may be at the time of turning on the power of the input device or at the start of character input, depending on what kind of total is desired to be obtained. May be changed according to the conditions. Volatile memory may be used if the accumulation is to be performed from power-on to power-off or from the start of character input to the end of character input. Is stored in a non-volatile memory such as a hard disk.

The character recognition dictionary 2-1 is the same as that of the first embodiment. However, when this embodiment is combined with another embodiment, the character recognition dictionary is adapted to the embodiment. .

As shown in FIG. 5C, a total and a character code are registered in the character code table 4-1. As in the case of determining the character code according to the score in step 1, the character code is determined according to the total. In the case of this embodiment, the display of the input reaction character image can be performed every time one character is input. However, in practice, a predetermined value is determined in advance to determine whether the total is small, normal, or large. It is preferable to display the input response character image by evaluating it at predetermined intervals. For example, considering the case where the present invention is applied to an electronic diary when determining the character code based on the total, the initialization of the total is performed for each day of the diary, and when the number of characters input when saving is less than 100 characters. ,"today,
Did not there happened so much? Or more than 300 characters, a message such as "What happened today?" Is output together with an input reaction character image having an expression matching the content of the message. In this case, for example, the total of the character code table 4-1 is 1 = 100, 2 = 300, and 3 = 999.
Here, 999 of the cumulative total 3 indicates all the items exceeding 300 of the cumulative total 2 immediately below. If the cumulative total is less than 100 characters, it is determined that the number is small.
It is determined that the number of characters is more than 01 characters.

The input response character image and message are
Since only a specific timing such as at the end of input is displayed,
At times other than the specific timing, a blank input response character image and a blank message may be displayed to clear the character display area and the message display area.

According to the present embodiment, the user, particularly a beginner, is motivated to input more handwriting, and becomes familiar with information equipment in order to promote more input.

In this embodiment, a time measuring unit and a character input speed calculating unit are further provided to determine the speed of characters input within a certain period of time, and to use the speed for inputting characters quickly or to record the speed history. By doing so, a message such as "Character input has become faster!" May be output.

[0062]

Embodiment 4 Next, an embodiment for displaying an input reaction character image in accordance with the character type of an input handwritten character will be described. In the configuration of the present embodiment, in FIG. 6, which is a configuration diagram of the second embodiment, the degree of difficulty transmitted from character recognition unit 2 to character code determination unit 4 merely changes with the character type. I do. Embodiment 2
The description of the same parts as described above will be appropriately omitted.

In this embodiment, the character recognition dictionary 2-1
Has data indicating a character type in addition to a character code and character feature information (two-dimensional image data or stroke information), as shown in FIG. The character type is, for example,
The types of hiragana, katakana, alphabets, numbers, and kanji, and further, the types of kanji are divided according to the type of character, and the input response character image displayed for each type of input character is changed.

The character recognizing unit 2 recognizes the input character using the character recognition dictionary 2-1. The character code of the recognized character is displayed on the character display unit 3, and the character type of the recognized character is the character code. Pass it to the decision unit 4. The character code determination unit 4 obtains a corresponding character code from the character code table 4-1 based on the character type, and the character display unit 5 generates a character code based on the character code.
The corresponding input response character image and message are retrieved from the character storage unit 5-1 in which the input response character image for each character type is registered, the input response character image is displayed, and the message is sent to the message output unit 7.
The message is output by the message output unit 7. The contents of the character code table 4-1 are as shown in FIG. As the input response character image by character type, for example, an input response character image with a mountain as a motif if the character is “Yama”, and an input response character image with a river as a motif if the character is “Sanzui”.

The input response character image and the message
It is erased and displayed for each character, but if the input response character image is not displayed until simple characters such as hiragana, numbers, and alphabets are input, if the character type is hiragana, numbers, alphabets, etc., As in the second embodiment, the character display area and the message display area may be cleared.

According to the present embodiment, in combination with the above-described embodiment, not only the input reaction character image having a different expression but the same input reaction character image is displayed, and the type of the input reaction character image to be displayed is input. It can be changed by handwritten characters. Therefore, changing the expression with the same input reaction character image will quickly get tired, but various input reaction character images will be displayed depending on the input characters. Can be done.

Here, an example of a screen of the handwriting input device obtained by combining the fourth embodiment with the first and second embodiments will be described with reference to FIG. FIG. 7A shows a screen at the time when a kanji character “hour” is handwritten in the handwritten character input / output area 11 of the screen 10 of the handwriting input device.
The input response character image is displayed in the character display area 12,
The message is displayed in the message display area 13, and there is a transfer button 14 for transferring characters input to a program such as a word processor when the character recognition is completed. Here, an example of a screen that focuses on the minimum functions required for a handwritten character input device is given, so when actually incorporating it into a program such as a word processor, use the buttons and input / output required for the word processor on the screen. There are areas. FIG. 7B shows an example in which the character “hour” input in FIG. 7A has a good score and the character is recognized to be beautiful. The kanji character of "time" is "day" and the characters are beautiful, so the input response character image with a happy expression of the sun is used as the input response character image that represents the "day", and the message is also shaped according to it Is displayed. In the screen shown in FIG. 7B, the character "hour" is followed by "e"
If you enter the characters
Since a difficult character is input, an input response character image of a surprised expression in the image of "mountain" is displayed, and a message is displayed accordingly. If the characters are beautiful and difficult, the message may be duplicated. In that case,
The message display area 13 may be displayed in two lines, and the number of character display areas may be two.

In the present embodiment, the character type is provided for each character in the character recognition dictionary 2-1. Instead of not having the character type, the character type determination unit is provided in the character recognition unit 2. Alternatively, the character type may be provided immediately after the character recognizing unit 2 to determine the character type based on whether or not the character characteristic information of the input character includes the characteristic information of the character or structure.

[0069]

Fifth Embodiment Next, FIG. 8 shows an example in which handwriting data of a character having a personal characteristic is additionally registered as character feature information of a corresponding character in the character recognition dictionary 2-1 at the time of handwriting input. It will be described using FIG. The description of the same portions as those of the other embodiments will be appropriately omitted. In the present embodiment, the character recognition dictionary 2-1 has a plurality of pieces of character feature information for characters for which handwriting data is additionally registered, as shown in FIG.

Normally, the character recognition dictionary 2-1 has character feature information created based on a standard font. However, when inputting handwritten characters, not all people input in standard fonts, and the fonts written by each person have characteristics.Therefore, a character recognition dictionary that stores character characteristic information of standard fonts In some cases, the recognition rate cannot be determined, which causes a reduction in the recognition rate. In this embodiment, even a person who writes a habit character facilitates character recognition by promoting the registration of a feature of a habit character, and a person who writes a habit character does not readily recognize a character. The purpose is to prevent such things from becoming disgusting.

The character input by handwriting is converted into character characteristic information by the character input unit 1 and sent to the character recognition unit 2. In the case where the character is not recognized by the character recognition unit 2, or because the character is a hazy character, it is registered. If you want to set up, click the registration button 15 on the screen.
The handwriting data registration unit 8 is activated by clicking, for example. The handwriting data registration unit 8 specifies the character by inputting the reading of the corresponding character by displaying a software keyboard on the screen or the like, and then uses the character characteristic information of the input handwritten character as character characteristic information of the corresponding character. , Character recognition dictionary 2
-1 is additionally registered in the standard character feature information of the corresponding character, and the total number of registered characters is counted and passed to the character code determination unit 4.

In a small mobile computer or the like, it is not possible to display all the Japanese syllabary simultaneously as a software keyboard.
It is advisable to prepare a button to move up and down so that the displayed row can be moved up and down to select it. When character feature information is additionally registered in the character code 2, the character recognition dictionary 2-1 of the present embodiment is as shown in FIG.

The accumulated registration number is stored in the handwriting data registration unit 8 (not shown). However, even if the power of the handwritten character input device is turned off, it is necessary to keep the stored number. Need to be stored in memory. As a result, the character feature information of the character is plural. If you want to increase the speed of character recognition, if the handwritten character input device is used by a specific individual such as a mobile computer, the character feature information of the additionally registered person will be prioritized and checked. If it is a common handwritten character input device to be used, standard character feature information may be given priority. The character code table 4-1 is the same as in the third embodiment, as shown in FIG. Since the character code determination unit 4 and subsequent steps differ only in the character code determined in accordance with the total number of registrations, and are the same as in the third embodiment, description thereof will be omitted.

The input response character image and the message
It is displayed only at the time of additional registration. In other cases, the character display area 12 and the message display area 13 may be cleared as in the second embodiment.

According to the present embodiment, it is possible to register the characteristics of individual fonts and to increase the character recognition rate, thereby facilitating the registration of hazy characters. This reduces the time and effort required to select a character from the list, thereby promoting handwritten character input.

In FIG. 7D, although the character "Large" was input by handwriting, it could not be recognized because it was a very cursive character, so the "A" line of the software keyboard 16 was placed at the position of the message display area 13. This is an example in which a reading display unit 17 is displayed, and a button for moving up and down and a registration button 15 are displayed next to it. When "dai" is input using the software keyboard 16, the character "dai" registered in the dictionary is displayed instead of "dai" input by handwriting. If the displayed character is different from the character to be input, a candidate list screen appears, and the corresponding character can be designated. When registering a hazy character in the character recognition dictionary 2-1, the registration button 15 may be pressed. When the transfer button 14 is pressed or the next handwritten character is entered, the screen returns to the original message display area 13.

Embodiment 6 This embodiment is different from Embodiment 5 in that the total number of characters input by handwriting and the corresponding character is recognized without selecting a recognized character candidate or rewriting the character. The present invention has a correct answer rate calculation unit that stores the total of the above and calculates the correct answer rate, thereby displaying the input reaction character image according to the correct answer rate. The configuration diagram of the present embodiment is a configuration diagram of the score calculation unit 6 in FIG.
Will be described with reference to FIG. 3 except that is replaced by a correct answer rate calculating unit, and the score sent from the score calculating unit 6 to the character code determining unit 4 becomes the correct answer rate. Embodiment 1
The description of the same parts as described above will be appropriately omitted.

The character recognizing section 2 corresponds to the input character without selecting a candidate or rewriting the character without selecting a candidate or rewriting the character. It has a correct answer flag (not shown) as to whether or not the character has been recognized. Character recognition unit 2
Each time a character is input, the correct flag is turned off prior to recognition. If the input character can be recognized without selecting a character candidate or rewriting the character, the correct flag is turned on. When the character recognition unit 2 finishes recognizing the character, the correct answer rate calculation unit inside the character recognition unit 2 calculates the total number of input characters by one.
In addition to counting up, refer to the correct answer flag. If the correct answer flag is on, count up the total number of correct answers by 1 and divide the total number of correct answers by the total number of input characters to obtain the correct answer rate, and calculate the correct answer rate with the character code. Decision part 4
Send to

The character code determination unit 4 determines the input response character image table 4- based on the received correct answer rate.
1 is selected, a character code corresponding to the correct answer rate is selected, and an input response character image is displayed on the character display unit 5 based on the input response character image data. The contents of the character code table 4-1 are as shown in FIG.

The input response character image based on the correct answer rate is
Although it is possible to display each time a character is entered, the accuracy rate does not fluctuate greatly for each character except when the number of entered characters is very small, so the accuracy rate fluctuates by more than a predetermined value. In this case, for example, it is preferable to display each time the correct answer rate changes by 10%. In this case, in order to check the variation of the correct answer rate, the character code determination unit 4 stores the variation rate at the time of displaying the previously input response character image, and stores the stored variation rate and the current variation. The rates are compared, and when the rate of change increases or decreases by 10%, a new character code is determined. The notification of the correct answer rate may be given by a message, or the correct answer rate may be included in the input response character image data and displayed for each correct answer rate. In this case, input response character image data including the correct response rate may be prepared, or when displaying the input response character image, the correct response rate may be embedded in the image data of the input response character image.

In the present embodiment, the input response character image and the message are displayed only when the correct answer rate fluctuates. In other cases, the character display area and the message display area are set in the same manner as in the second embodiment. Good to clear.

According to the present embodiment, in order to increase the correct answer rate, it is possible to further promote the registration of the custom character and to acquire a habit of writing the character carefully.

Next, a recording medium in which a program for realizing the handwritten character input device according to the first to sixth embodiments of the present invention is described, as in the example of the recording medium shown in FIG.
