[0028] <2. Operation of the Class Support System> Next, the first class support process, which is a process performed on the electronic blackboard 3 by the server 2, will be described. FIG. 4 shows a flowchart showing the flow of the first class support process.

[0029] (First Class Support Process) First, the CPU 21 performs teacher login authentication (step A1). Specifically, the CPU 31 of the electronic blackboard 3 transmits a teacher login request to the server 2 via the communication unit 36 based on an input operation by the teacher via the operation unit 32. When the CPU 21 of the server 2 receives the login request from the electronic blackboard 3 via the communication unit 26, it generates login screen data and transmits it to the electronic blackboard 3 that is the request source. Next, the CPU 31 of the electronic blackboard 3 receives the login screen data from the server 2 via the communication unit 36 and displays it on the display unit 34, accepts the input of the ID and password by the teacher via the operation unit 32, and transmits the ID and password to the server 2 via the communication unit 36. Next, when the CPU 21 of the server 2 receives the teacher's ID and password from the electronic blackboard 3 via the communication unit 26, it performs teacher login authentication based on whether the received teacher's ID and password match the teacher's account information stored in the account database D3. The CPU 21 of the server 2 executes the following processing for the electronic blackboard 3 that is the transmission source of the ID and password for which the login authentication has succeeded.

[0030] Next, the CPU 21 sets the target school year of the class (step A2). Specifically, the CPU 21 sets the target school year of the class based on an input operation by the teacher via the operation unit 32 of the electronic blackboard 3. If school year information is associated with the teacher's account information for which the CPU 21 performed login authentication in step A1, the CPU 21 may set the target school year of the class based on the school year information.

[0031] Next, the CPU 21 receives a handwritten input operation on the touch panel of the operation unit 32 of the electronic blackboard 3. The handwritten input is an input using the locus of coordinates where the user's hand, pen, etc. are in contact with the touch panel of the operation unit 32. Then, the CPU 21 causes a handwritten object based on the handwritten input operation to be displayed on the display unit 34 of the electronic blackboard 3 (step A3). That is, the content handwritten in the teacher's account is reflected in the display in the teacher's account. The teacher's account is the account for which the login authentication was successful in step A1. Note that the handwritten object is an object (display item) to be displayed on the display unit, such as a drawing line generated by a coordinate data series where the user's hand, pen, etc. are in contact with the touch panel of the operation unit 32. Further, the handwritten object includes symbols or symbol strings such as characters and numbers, and figures such as straight lines and curves. FIG. 5 shows an example of the display screen 341 of the display unit 34 on which the handwritten object is displayed.

[0032] Next, the CPU 21 executes character recognition processing on the handwritten object displayed in step A3. Then, the CPU 21 determines whether a handwritten character was displayed as the handwritten object in step A3, that is, whether a handwritten character was input on the touch panel of the operation unit 32 (step A4). In step A4, the CPU 21 recognizes the input handwritten character each time a handwritten character is input. The CPU 21 functions as a recognition unit. Step A4 is a recognition step.

[0033] When a handwritten character is input on the touch panel of the operation unit 32 (step A4; YES), the CPU 21 determines whether the input handwritten character is a kanji character (step A5). If the input handwritten character is a kanji character (step A5; YES), the CPU 21 refers to the kanji database D1 and determines whether the input kanji character is classified as a kanji character taught in a grade higher than the target grade of the lesson set in step A2 (step A6). If the input kanji character is classified as a kanji character taught in a grade higher than the target grade of the lesson set in step A2 (step A6; YES), the CPU 21 displays the kanji character displayed on the display unit 34 with a warning mark (step A7). In other words, in step A7, if the recognized handwritten character is a kanji character that does not correspond to a predetermined learning range among a plurality of pre-registered kanji characters (kanji character taught in a grade higher than the target grade of the lesson set in step A2), the CPU 21 adds a first mark (warning mark) to the handwritten character and displays the handwritten character on the display unit 34. In other words, this first mark (warning mark) is reflected (displayed) on the display of the teacher's account. The CPU 21 functions as a display control unit. Step A7 is a display control step. FIG. 6 shows an example of a display screen 341 of the display unit 34 on which the warning mark M1 is displayed. In the example shown in FIG. 6, the handwritten object (handwritten character) "gyaku" is a kanji that is learned in a grade higher than the target grade of the lesson. In the example shown in FIG. 6, the target grade of the lesson is set to fourth grade, and "gyaku" is classified as a kanji that is learned in fifth grade in the kanji database D1. As shown in FIG. 6, the CPU 21 displays a number indicating the grade in which the kanji will be learned on the warning mark M1.

[0034] Next, the CPU 21 determines whether or not a touch operation on the warning mark M1 has been received on the touch panel of the operation unit 32 of the electronic whiteboard 3 (step A8). If a touch operation on the warning mark M1 has been received (step A8; YES), the CPU 21 displays a display selection menu on the display unit 34 and receives a selection of a display method for the kanji characters marked with the warning mark M1 (step A9). FIG. 7 shows an example of a display screen 341 of the display unit 34 on which a display selection menu 342 is displayed. As shown in FIG. 7, the CPU 21 displays, as options, a "Replace with Kana" button 342a, a "Ruby" button 342b, and a "Dictionary Link" button 342c in the display selection menu 342. The CPU 21 also displays a cancel button 342d in the display selection menu 342, which instructs the teacher to close the display selection menu 342. In other words, the display selection menu is reflected (displayed) in the display of the teacher's account.

[0035] Next, the CPU 21 determines whether the "Replace with Kana" button 342a in the display selection menu 342 has been selected (touched) (step A10). If the "Replace with Kana" button 342a has been selected (step A10; YES), the CPU 21 deletes the warning mark M1 displayed in step A7. The CPU 21 also obtains the pronunciation of the kanji to which the warning mark M1 was attached from the kanji database D1, replaces the kanji with the pronunciation (kana), and updates the display on the display unit 34 (step A11). That is, the replacement process of replacing the kanji with the pronunciation (kana) in step A11 is reflected in the display on the teacher's account. FIG. 8 shows an example of a display screen 341 of the display unit 34 on which the kanji has been replaced with the kana. In the example shown in FIG. 8, the CPU 21 replaces the kanji "gyaku" (reverse), which was attached with the warning mark M1, with the pronunciation "gyaku" (gaku) in type using a predetermined font and displays it. Next, the CPU 21 shifts the first lesson support process to step A20.

[0036] On the other hand, if the "Replace with Kana" button 342a is not selected (step A10; NO), the CPU 21 determines whether the "Add Ruby" button 342b has been selected (touched) in the display selection menu 342 (step A12). If the "Add Ruby" button 342b has been selected (step A12; YES), the CPU 21 deletes the warning mark M1 displayed in step A7. The CPU 21 also acquires the reading of the kanji to which the warning mark M1 was attached from the kanji database D1, adds reading to the kanji as the reading (adding ruby), and updates the display on the display unit 34 (step A13). In other words, the reading added to the kanji by the first adding process in step A13 is reflected in the display on the teacher's account. FIG. 9 shows an example of a display screen 341 of the display unit 34 in which the kanji is displayed with ruby. In the example shown in Fig. 9, the CPU 21 displays the reading "gyaku" in type using a predetermined font as ruby to the kanji character "gyaku" to which the warning mark M1 was attached. Next, the CPU 21 moves the first lesson support process to step A20. Note that the reading is not necessarily limited to being added using furigana, and for example, the reading may be added in parentheses next to the kanji character, such as "gyaku".

[0037] On the other hand, if the "Ruby" button 342b is not selected (step A12; NO), the CPU 21 determines whether the "Dictionary Link" button 342c in the display selection menu 342 has been selected (touched) (step A14). If the "Dictionary Link" button 342c has been selected (step A14; YES), the CPU 21 displays a dictionary selection menu on the display unit 34 and accepts the selection of a dictionary for looking up the kanji marked with the warning mark M1 as a headword (step A15). In other words, the dictionary menu is reflected (displayed) in the display of the teacher's account. FIG. 10 shows an example of a display screen 341 of the display unit 34 on which the dictionary selection menu 343 is displayed. As shown in FIG. 10, the CPU 21 displays cover images 343a of each dictionary as a choice in the dictionary selection menu 343. Data of the dictionaries as choices in the dictionary selection menu 343 is stored in the dictionary database D2. In addition, the CPU 21 may display a button displaying the name of the dictionary in place of the dictionary cover image 343a in the dictionary selection menu 343. Next, the CPU 21 deletes the warning mark M1 displayed in step A7. The CPU 21 also adds a dictionary link mark as a second mark to the kanji character to which the warning mark M1 was attached, and updates the display on the display unit 34 (step A16). In other words, the dictionary link mark added by the second addition process in step A16 is reflected (displayed) in the display on the teacher's account. FIG. 11 shows an example of a display screen 341 of the display unit 34 on which the kanji character is displayed with the dictionary link mark M2 attached. In the example shown in FIG. 11, the CPU 21 displays the kanji character "gyaku" (reverse), which was previously marked with the warning mark M1, with the dictionary link mark M2 attached. For example, the dictionary link mark M2 is displayed as the cover image of the dictionary selected in step A15.

[0038] Next, the CPU 21 determines whether or not a touch operation on the touch panel of the operation unit 32 of the electronic blackboard 3 has been received for the dictionary link mark M2 (step A17). When a touch operation on the touch panel of the operation unit 32 of the electronic blackboard 3 has been received for the dictionary link mark M2 (step A17; YES), the CPU 21 uses the Chinese character with the dictionary link mark M2 as the search word and displays the result of dictionary lookup in the dictionary selected in step A15 on the display unit 34 (step A18). That is, the result of dictionary lookup based on the touch operation on the dictionary link mark M2 on the touch panel of the operation unit 32 of the electronic blackboard 3 is reflected (displayed) in the display under the teacher's account. FIG. 12 shows an example of the display screen 341 of the display unit 34 on which a dictionary content screen 344 is displayed, which displays the search word and explanatory information that are the results of dictionary lookup using the Chinese character with the dictionary link mark M2 as the search word. Next, the CPU 21 proceeds to step A20 for the first class support process.

[0039] On the other hand, when a touch operation on the dictionary link mark M2 is not received (step A17; NO), the CPU 21 proceeds to step A20 for the first class support process.

[0040] Also, when the "Dictionary Link" button 342c is not selected (step A14; NO), the CPU 21 determines whether or not the cancel button 342d has been touch-operated in the display selection menu 342 (step A19). When the cancel button 342d is not touch-operated (step A10; NO), the CPU 21 proceeds to step A10 for the first class support process.

[0041] On the other hand, when the cancel button 342d is touch-operated (step A19; YES), the CPU 21 proceeds to step A20 for the first class support process. Next, the CPU 21 determines whether it has received an instruction to end the handwritten input operation to the electronic blackboard 3 based on the input operation by the teacher via the operation unit 32 of the electronic blackboard 3 (step A20). When it has received an instruction to end the handwritten input operation to the electronic blackboard 3 (step A20; YES), the CPU 21 ends the first class support process. On the other hand, when it has not received an instruction to end the handwritten input operation to the electronic blackboard 3 (step A20; NO), the CPU 21 proceeds to step A3 in the first class support process.

[0042] Also, when no handwritten characters are input on the touch panel of the operation unit 32 (step A4; NO), when the input characters are not Chinese characters (step A5; NO), when the input Chinese characters are classified as Chinese characters learned in a school year equal to or lower than the target school year of the class (step A6; NO), or when no touch operation on the warning mark M1 has been received (step A8; NO), the CPU 21 proceeds to step A20 in the first class support process.

[0043] Next, the second class support process, which is the process by the server 2 for the student terminal 4, will be described. The server 2 executes the second class support process in parallel with the first class support process. FIG. 13 shows a flowchart indicating the flow of the second class support process.

[0044] (Second class support process) First, the CPU 21 performs student login authentication (step B1). Specifically, the CPU 41 of the student terminal 4 transmits a student login request to the server 2 via the communication unit 46 based on an input operation by the student via the operation unit 42. When the CPU 21 of the server 2 receives the login request from the student terminal 4 via the communication unit 26, it generates login screen data and transmits it to the student terminal 4 that is the request source. Next, the CPU 41 of the student terminal 4 receives the login screen data from the server 2 via the communication unit 46 and displays it on the display unit 44, accepts the input of the ID and password by the student via the operation unit 42, and transmits the ID and password to the server 2 via the communication unit 46. Next, when the CPU 21 of the server 2 receives the student's ID and password from the student terminal 4 via the communication unit 26, it performs student login authentication based on whether the received student's ID and password match the student's account information stored in the account database D3. The CPU 21 of the server 2 executes the following processing for the student terminal 4 that is the transmission source of the ID and password for which the login authentication has succeeded.

[0045] Next, the CPU 21 determines whether a handwritten input operation has been received on the touch panel of the operation unit 32 of the electronic blackboard 3 in step A3 of the first class support process (step B2). If a handwritten input operation has not been received on the touch panel of the operation unit 32 of the electronic blackboard 3 (step B2; NO), the CPU 21 returns to step B2 of the second class support process. On the other hand, if a handwritten input operation has been received on the touch panel of the operation unit 32 of the electronic blackboard 3 (step B2; YES), the CPU 21 causes a handwritten object based on the handwritten input operation to be displayed on the display unit 44 of the student terminal 4 as shown in FIG. 5 (step B3). That is, the content handwritten with the teacher's account is reflected not only in the teacher's account but also in the display with the student's account. The student's account is the account for which the login authentication has succeeded in step B1.

[0046] Next, the CPU 21 determines whether to execute a replacement process of replacing the Chinese characters in step A11 of the first class support process with reading kana (step B4). When executing the replacement process (step B4; YES), as shown in FIG. 8, the CPU 21 replaces the Chinese characters marked with the warning mark M1 in the first class support process with reading kana, and updates the display on the display unit 44 (step B5). That is, the replacement process is reflected in the display not only in the teacher's account but also in the student's account. Next, the CPU 21 proceeds to step B12 of the second class support process.

[0047] On the other hand, when not executing the replacement process (step B5; YES), the CPU 21 determines whether to execute a first addition process of adding furigana as reading kana to the Chinese characters in step A13 of the first class support process (step B6). When executing the first addition process (step B6; YES), as shown in FIG. 9, the CPU 21 adds furigana as reading kana to the Chinese characters marked with the warning mark M1 in the first class support process (puts on ruby), and updates the display on the display unit 44 (step B7). That is, the first addition process is reflected in the display not only in the teacher's account but also in the student's account. Next, the CPU 21 proceeds to step B12 of the second class support process.

[0048] On the other hand, when not executing the first addition process (step B6; NO), the CPU 21 determines whether to execute a second addition process of adding a dictionary link mark to the Chinese characters in step A16 of the first class support process (step B8). When executing the second addition process (step B8; YES), as shown in FIG. 11, the CPU 21 adds a dictionary link mark M2 to the Chinese characters marked with the warning mark M1 in the first class support process, and updates the display on the display unit 44 (step B9). That is, the dictionary link mark added by the second addition process is reflected in the display not only in the teacher's account but also in the student's account.

[0049] Next, the CPU 21 determines whether or not a touch operation on the touch panel of the operation unit 42 of the student terminal 4 has been received for the dictionary link mark M2 (step B10). When a touch operation on the touch panel of the operation unit 42 of the student terminal 4 has been received for the dictionary link mark M2 (step B10; YES), the CPU 21 displays, on the display unit 44, the result of dictionary lookup in the dictionary selected in step A15 of the first class support process, using the Chinese character with the dictionary link mark M2 as the search term (step B11). That is, the result of the dictionary lookup based on the touch operation on the touch panel of the operation unit 42 of the student terminal 4 for the dictionary link mark M2 is reflected (displayed) in the display for the student's account and is not reflected (not displayed) in the display for the teacher's account. When the class support system 1 includes a plurality of student terminals 4 (when the account database D3 stores account information for a plurality of students), the CPU 21 makes a determination as to whether or not a touch operation on the dictionary link mark M2 has been received for each student terminal 4. Then, the CPU 21 displays the result of the dictionary lookup only on the display unit 44 of the student terminal 4 for which a touch operation on the dictionary link mark M2 has been received.

[0050] On the other hand, when the second additional process is not executed (step B8; NO), or when a touch operation on the touch panel of the operation unit 42 of the student terminal 4 has not been received for the dictionary link mark M2 (step B10; NO), the CPU 21 proceeds to step B12 of the second class support process. Next, the CPU 21 determines whether or not an instruction to end the handwriting input operation on the electronic blackboard 3 has been received in step A20 of the first class support process (step B12). When an instruction to end the handwriting input operation on the electronic blackboard 3 has been received (step B12; YES), the CPU 21 ends the second class support process. On the other hand, when an instruction to end the handwriting input operation on the electronic blackboard 3 has not been received (step B12; NO), the CPU 21 proceeds to step B2 of the second class support process.

[0051] As described above, in the second class support process, the CPU 21 does not display the first mark (warning mark) on the Chinese characters displayed on the display unit 44. That is, the first mark (warning mark) is not reflected (hidden) in the display on the student's account. Therefore, this first mark (warning mark) cannot be operated on the student's account. Note that this first mark (warning mark) may also be configured to be displayed in the student's account so that it cannot be operated on the student's account. Also, in the second class support process, the CPU 21 does not display the display selection menu on the display unit 44. That is, the display selection menu is not reflected (hidden) in the display on the student's account. Further, in the second class support process, the CPU 21 does not display the dictionary menu on the display unit 44. That is, the dictionary menu is not reflected (hidden) in the display on the student's account.

[0052] <3. Effect> As described above, the educational assistance device (server 2) of the present embodiment includes a recognition unit (CPU 21) that recognizes the input handwritten characters each time the handwritten characters are input, and when the handwritten characters recognized by the recognition unit are Chinese characters that do not correspond to a predetermined learning range among a plurality of pre-registered Chinese characters, a display control unit (CPU 21) that adds a first mark (warning mark M1) for displaying a predetermined menu (display selection menu 342) to the handwritten characters and displays them on the display unit 34 of the electronic blackboard 3. Therefore, even when a teacher accidentally writes a Chinese character outside the learning range for the grade of the students receiving the class on the electronic blackboard, by adding the first mark (warning mark M1) to the Chinese character, attention can be drawn to the Chinese character. Also, a predetermined menu can be displayed. Thereby, the learning effect of the students' Chinese characters can be improved.

[0053] Also, in the educational assistance device (server 2) of the present embodiment, when an operation is performed on the first mark (warning mark M1), the display control unit (CPU 21) displays a menu (display selection menu 342) including, as options, the display of reading kana corresponding to the handwritten characters and the display of a second mark (dictionary link mark M2) for displaying the content of a predetermined dictionary corresponding to the handwritten characters. Therefore, even when a teacher accidentally writes a Chinese character outside the learning range in the academic year of the students receiving the lesson on the electronic blackboard, the students can learn the reading kana of the Chinese character outside the learning range by the display of the reading kana corresponding to the Chinese character outside the learning range. Alternatively, by displaying the content of a predetermined dictionary corresponding to the Chinese character outside the learning range with the second mark (dictionary link mark M2), the students can learn the explanatory information about the Chinese character outside the learning range.

[0054] Also, in the educational assistance device (server 2) of the present embodiment, as the display of the reading kana corresponding to the handwritten characters, the display control unit (CPU 21) replaces the handwritten characters with reading kana and displays them, or adds the reading kana to the handwritten characters and displays them. Therefore, when the handwritten characters are replaced with reading kana and displayed, it is possible to prevent the students from being confused by the writing of Chinese characters they have not learned. Also, when the reading kana is added to the handwritten characters and displayed, the students can learn the reading kana together with the notation for Chinese characters outside the learning range.

[0055] In the above description, an example in which the storage units 25, 35, 45 (HDD, SSD) are used as the computer-readable medium of the program according to the present invention has been disclosed, but the present invention is not limited to this example. As other computer-readable media, it is possible to apply flash memory, portable recording media such as CD-ROMs, etc. Also, a carrier wave is also applied to the present invention as a medium for providing the data of the program according to the present invention via a communication line.

[0056] Note that the description in the above embodiment is merely an example of the educational assistance device and program according to the present invention, and is not limited thereto. For example, in the above embodiment, the case where the execution entity of the first class support process and the second class support process is the CPU 21 of the server 2 is illustrated, but it is not limited thereto. For example, the CPU 31 of the electronic blackboard 3 may execute the first class support process and the second class support process. In this case, the CPU 31 of the electronic blackboard 3 corresponds to the "recognition unit" and the "display control unit", and the electronic blackboard 3 corresponds to the "educational assistance device". Also, regarding the first class support process and the second class support process, part of the processes may be executed by the CPU 21 of the server 2, and the remaining processes may be executed by the CPU 31 of the electronic blackboard 3.

[0057] Also, although the dictionary database D2 has been described as being stored in the storage unit 25 of the server 2, it is not limited thereto. The dictionary database D2 may be stored in the storage unit 45 of the student terminal 4. In this case, the storage unit 25 of the server 2 as the educational assistance device stores information for specifying the dictionary stored in the student terminal 4.

[0058] Also, the class support system 1 may further include a teacher terminal such as a tablet terminal communicatively connected to the server 2 via a communication network. In this case, the teacher terminal receives a handwritten input operation by the teacher via its operation unit, and transmits a signal based on the handwritten input operation to the server 2. Next, the CPU 21 of the server 2 receives the signal based on the handwritten input operation from the teacher terminal, and causes a handwritten object based on the handwritten input operation to be displayed on the display unit of the teacher terminal, the display unit 34 of the electronic blackboard 3, and the display unit 44 of the student terminal 4.

[0059] Further, the class support system 1 may be provided with the teacher terminal instead of the electronic blackboard 3 without the electronic blackboard 3. In this case, the teacher terminal receives a handwritten input operation by the teacher via its own operation unit, and transmits a signal based on the handwritten input operation to the server 2. Next, the CPU 21 of the server 2 receives a signal based on the handwritten input operation from the teacher terminal, and causes a handwritten object based on the handwritten input operation to be displayed on the display unit of the teacher terminal and the display unit 44 of the student terminal 4.

[0060] Also, in step A3 of the first class support process and step B3 of the second class support process, the CPU 21 of the server 2 causes a handwritten object based on a handwritten input operation on the touch panel of the operation unit 32 of the electronic blackboard 3 to be displayed on the display unit 34 of the electronic blackboard 3 and the display unit 44 of the student terminal 4, but it is not limited to this. When characters are input by a handwritten input operation on the touch panel of the operation unit 32 of the electronic blackboard 3, the CPU 21 may convert the input handwritten characters into typefaces using a predetermined font, and cause the converted characters to be displayed on the display unit 34 of the electronic blackboard 3 and the display unit 44 of the student terminal 4.

[0061] Also, although the display unit 34 of the electronic blackboard 3 has been described as having a display panel, it may alternatively have a projector.

[0062] As described above, some embodiments of the present invention have been described, but the scope of the present invention is not limited to the above-described embodiments, and includes the scope of the invention described in the claims and the equivalent scope thereof.
