  The answer character frame management table storage unit 3 is composed of a storage device such as a hard disk, generates an answer character frame including the calculation process for the writing question stored in the writing question database 11, and the answer character frame. The answer character frame management table in which at least the display position, size, and correct answer information are associated is stored.

  The handwriting display unit 5 performs display control for displaying the handwriting input from the handwriting input unit 1 at a predetermined position on the display unit 4, and can also display the handwriting information input by the learner as it is. Yes, if necessary, it can be converted into predetermined symbol or character information and displayed on the display unit 4.

  The answer area determination unit 2 determines whether or not the handwriting information received from the handwriting input unit 1 is input in the answer character frame, and is stored in the answer character frame management table storage unit 3. With reference to the answer character frame management table, it is determined whether or not the handwriting information received by the handwriting input unit 1 is input into the answer character frame.

  The handwriting storage unit 6 stores handwriting information received from the handwriting input unit 1.

  The scoring instruction unit 7 instructs to determine whether or not the answer input is correct when the answer input to the writing problem is completed, and may be configured by a switch attached to the writing learning support apparatus. It is also possible to configure as a software switch displayed on the display unit 4 configured integrally with the pen-type tablet.

  The character recognition unit 8 refers to the character recognition dictionary 9 to determine what character (in this case, a number) the handwriting information input in the answer character frame is. For this character recognition method, it is possible to adopt an existing character recognition engine, for example, using a character recognition engine such as an offline recognition engine, an online recognition engine, or a hybrid recognition engine that combines them. Candidate characters can be extracted, and the closest candidate can be determined from the recognition candidate characters.

  The scoring unit 10 performs scoring processing by comparing the answer information recognized by the character recognition unit 8 with the correct answer information managed in the answer character frame management table, and displays the scoring result to a predetermined position on the display unit 4. Perform display control.

  The operation of the first embodiment of the present invention will be described based on the flowchart shown in FIG.

  In step S11, the handwriting learning support device selects a handwriting problem. The problem selection for writing can be made by selecting a problem from the writing problem database 11 in which the writing problem is stored in advance based on the type of addition / subtraction / division / division, difficulty, and the like. An example of the writing calculation problem database 11 is shown in FIG. In FIG. 17, numbers are registered in advance, but numbers may be randomly generated and problems associated with operators may be automatically generated.

  In step S12, the writing learning support apparatus determines an answer character frame including a calculation process for the selected question, sets a display position and a size for displaying each answer character frame on the display unit 4, and sets each answer character frame. An answer character frame management table in which correct answer information to be input of answer character frames is associated is generated.

  In step S13, the writing learning support apparatus displays on the display unit 4 an answer character frame including the problem earned in step S12 and a calculation process for the problem.

  For example, in the case where writing of (12 × 38) 2 digits × 2 digits is a problem, the question screen 100 is displayed on the display unit 4 as shown in FIG. The question screen 100 includes a question display unit 101, a calculation process character frame display unit 102, and a final answer character frame display unit 103. In the case of this problem, seven answer character frames 104a to 104g are indispensable for the calculation process character frame display unit 102 and the final answer character frame display unit 103, and the writing learning support device includes these answer character frames 104a to 104g. For each frame ID, an answer character frame management table is generated in which the display position, the display size, and the correct answer information to be input are associated with each other. An answer character frame management table according to this example is shown in FIG.

  In the answer character frame management table shown in FIG. 4, the frame ID assigned to the answer character frames 104a to 104g is associated with the display position, display size, correct answer information, answer attribute, character frame attribute, and the like. . The attribute of the character frame indicates whether the answer information input in the answer character frame is a calculation process or a final answer. In the illustrated example, the character frame corresponding to the frame IDs 1 to 4 The attribute is “calculation process”, and the character frame attribute corresponding to the frame IDs 5 to 7 is set to “answer”. In step S12, such an answer character frame management table is stored in the answer character frame management table storage unit 3. In step S13, an answer character frame including a question and a calculation process is displayed based on the answer character frame management table. 100 is displayed on the display unit 4.

  In step S14, the handwriting learning support device accepts the learner's handwriting information input from the pen-type tablet. The learner inputs an answer to the answer character frame with a stylus pen or the like.

  In step S15, the handwriting learning support device displays the input handwriting information on the display unit 4. The handwriting display unit 5 can be configured to display the input handwriting information as it is in the corresponding area of the display unit 4, and the handwriting information that has been input out of the answer character frame is also input. It can be configured to reflect and display as it is.

  For example, in the answer text boxes 104a to 104b, '96' is input as the calculation process by multiplying the upper '12' by the lower first digit '8', and this is displayed as the answer handwriting. To do. At this time, the user inputs “6”, which is the first digit out of “16” which is the result of multiplication of the first digit “2” in the upper row and the first digit “8” in the lower row, into the answer character frame 104b. Then, “1” in the tenth place can be written as the memo handwriting 105 a outside the answer character frame and displayed on the display unit 4. Similarly, when a carry occurs in the calculation process, it can be input as a memo handwriting 105b and displayed on the display unit 4.

  At this time, the handwriting information input from the handwriting input unit 1 is simultaneously stored in the handwriting storage unit 6.

  In step S16, the handwriting learning support device determines whether or not the answer input to the answer character frame on the question screen 100 has been completed. Whether or not the answer input has ended can be determined that the input of the answer information has ended when a predetermined time has elapsed after the handwriting input unit 1 has received the handwriting information. An end instruction button for instructing the end of the operation may be set by a hard switch or a soft switch, and a determination may be made based on an instruction of the end instruction button. When it is determined that the answer input has been completed, the writing learning support device proceeds to step S17, and otherwise proceeds to step S14.

  In step S17, the writing learning support device determines whether or not there is a scoring instruction. When the scoring instruction unit 7 is operated by the learner or the teacher, the writing learning support device determines that there is a scoring instruction, and the process proceeds to step S18. Otherwise, the process proceeds to step S21.

  In step S20, the handwriting learning support device performs character recognition on the answer handwriting input to each answer character frame by the learner.

  Here, the handwriting learning support device first determines whether or not the input handwriting information is input in the answer character frame. The answer area determination unit 2 refers to the answer character frame management table stored in the answer character frame management table storage unit 3, and to which answer character frame the handwriting information input from the learner is input, or the answer character It is determined whether the input is outside the frame. As a method of determining in which area the input handwriting information is input, for example, when it is determined that the input barycentric coordinates are within the answer character frame, It is determined that the input is in the answer character frame. In such a configuration, even if the start point or end point of the input stroke is out of the answer character frame, it can be determined that the input is in the answer character frame. It is possible to cope with even a case where the part protrudes from the answer character frame. For each stroke, determine which answer character frame is input or whether the input is outside the answer character frame, and perform character recognition only for handwriting that is determined to be input within the answer character frame. .

  The character recognition unit 8 refers to the character recognition dictionary 9 and performs character recognition processing of the answer handwriting input in the answer character frames 104a to 104g of the question screen 100. As described above, the character recognition method can use a commonly used online recognition engine, offline recognition engine, or a hybrid recognition engine that combines them, and the result of character recognition by the character recognition unit 8. The answer information is transmitted to the scoring unit 10.

  In step S19, the handwriting learning support device compares the answer information subjected to character recognition processing with the correct answer information managed in the answer character frame management table, determines whether or not they match, and performs scoring.

  In step S20, the writing learning support apparatus displays the result of scoring by the scoring unit on the display unit 4. The scoring result by the scoring unit 10 is displayed on the question screen 100 when the answer information, which is the character recognition result for all answer character frames, matches the correct answer information managed in the answer character frame management table. If there is answer information that does not match, and a check mark or a question mark is displayed in the corresponding answer character frame of the question screen 100, there is a method. Furthermore, it is also possible to arrange so that points are assigned to each answer character frame, and the score calculated based on the correct answer / incorrect answer of each answer information is displayed in a predetermined area of the display unit 4.

  An example of the display screen of an example in which the scoring results are displayed on the display unit 4 is shown in FIG. In FIG. 18, of the four numbers entered in the calculation process character frame, three are correct and one is incorrect, and 75 points are displayed as the calculation process score. Also, since the two numbers entered in the answer character frame do not all match the correct number, the answer is displayed as incorrect. In this way, even if the answer is the same incorrect answer, it is easy to grasp to what extent the calculation process can be understood.

  In step S21, the writing learning support apparatus determines whether or not to select the next problem. When a predetermined time has elapsed since the scoring process was completed, when a predetermined time has elapsed since the last input of handwriting information, or when an instruction to select the next question was received from the learner Then, the process proceeds to step S11, and the process proceeds to the next problem selection process. If not, the process ends.

The configurations of the character recognition dictionary 9, the scoring unit 10, and the writing problem database 11 can be the same as those in the first embodiment, and detailed description thereof is omitted here.

  In a writing problem that includes a decimal point, the final answer includes a decimal point. Therefore, when such a question is given, it is necessary to prepare an answer character frame for inputting the decimal point. In the third embodiment, a decimal point determination unit 30 is provided for determining how much a decimal point is input in such a final answer.

  Let us consider the case where a multiplication with a decimal point (1.2 x 3.8) is given. As shown in FIG. 8, a question screen 110 is displayed on the display unit 4. The question screen 110 includes a question display unit 111, a calculation process character frame display unit 112, and a final answer character frame display unit 113. In this case, the calculation process character frame display unit 112 and the final answer character frame display unit 113 include the seven answer character frames 114a to 114g, and the final answer character frame display unit 113 includes the decimal point answer character frames 115a to 115a. Set 115b. The decimal point answer character frames 115 a to 115 b can be configured to be displayed as answer character frames having a small size between the digits of the final answer character frame display unit 103.

  In the answer character frames 114a to 114g and the decimal point answer character frames 115a to 115b, the display position, display size, correct answer information, and attribute information thereof are associated with each other by an answer character frame management table as shown in FIG. Here, for the answer character frames 114a to 114g, 'number' is set in the attribute column, and the corresponding number is stored in the correct answer information column. Also, for the decimal point answer character frames 115a to 115b, 'decimal point' is set in the attribute column, the correct answer information column of the decimal point answer character frame to which the decimal point is to be attached is '1', and the decimal point is attached. The correct answer information field of the decimal point answer character frame that should not be set is set to '0'.

  In this case, the decimal point determination unit 30 determines that the decimal point is applied if there is handwriting information input in the decimal point answer character frames 115a to 115b, and the decimal point is applied if there is no input handwriting information. Judge that there is no. Therefore, the decimal point determination unit 30 can perform character recognition of the decimal point answer character frame by a method different from the handwriting information input to other answer character frames, and can reliably recognize the decimal point.

<Fourth embodiment>
A schematic configuration of the fourth embodiment of the present invention is shown in FIG.

  The handwriting learning support device according to the fourth embodiment includes a handwriting input unit 1, an answer area determination unit 2, an answer character frame management table storage unit 3, a display unit 4, a handwriting display unit 5, a handwriting storage unit 6, and a scoring instruction unit. 7, character recognition unit 8, character recognition dictionary 9, scoring unit 10, writing problem database 11, and carry-down symbol determination unit 41.

The configuration of the character recognition dictionary 9, the scoring unit 10, and the writing problem database 11 can be the same as that of the first embodiment, and detailed description thereof is omitted here.

  In writing that causes a carry-down, the carry-down symbol is entered in a form that overwrites the number written in the answer text box. In this case, there is a problem in that the previously entered numbers and carry-down symbols overlap and accurate character recognition cannot be performed. For this reason, in the present embodiment, a carry-down symbol determination unit 41 is provided for recognizing the carry-down symbol input in the answer character frame and accurately identifying the handwriting information input earlier.

  For example, as shown in FIG. 11, consider the case of performing division (8568 ÷ 36) by handwriting.

  The question screen 120 displayed on the display unit 4 includes a question display unit 121, a calculation process character frame display unit 122, and a final answer character frame display unit 123. In the case of this problem, answer character frames 124-1 to 124-28 are set in the calculation process character frame display unit 122 and the final answer character frame display unit 123, and it is possible to display answer character frames that are not necessarily required. It is structured so that it does not serve as a hint for correct answers to learners.

  As a result of dividing the first two digits of the subject dividend '85' by the divisor '36', '2' is input to the answer character frame 124-2 located at the 100th place of the final answer character frame 123, and the calculation process In the first two digits of the first column of the character frame display unit 122, “72”, which is the calculation result of “2 × 36”, is input, and the calculation process character frame display unit 122 starts from the first two digits “85” of the dividend. The result of subtracting '72' entered in the first two digits of the first column and the value of the third digit of the dividend being lowered are entered in the first three digits of the second column of the calculation process character frame display unit 122. It should be. As a result, a value of “136” should be input in the first three digits of the second column of the calculation process character frame display unit 122.

  As a result of dividing the current value '136' in the second column of the calculation process character frame display unit 122 by the divisor '36' as a dividend, the answer character frame 124-3 positioned at the 10th place of the final response character frame 123 “3” is input, and “108”, which is the operation result of “3 × 36”, is input to the first three digits of the third column of the calculation process character frame display unit 122. The result of subtracting “108” input to the first three digits of the third column of the calculation process character frame display unit 122 from the current value “136” of the first three digits of the second column, and the fourth digit of the dividend The value dropped to べ き should be input to the fourth column of the calculation process character frame display unit 122.

  At this time, a carry-down occurs in the answer character frame 124-10 in the second digit from the top of the second column of the calculation process character frame display unit 122, and the carry-down symbol 125 is entered in the answer character frame 124-10. It is usually done to enter the number after moving down to the outside.

  The carry-down symbol determination unit 41, when the handwriting information has already been input to the answer character frame 124-10, and the diagonal line from the upper left to the lower right is further input as the handwriting information, the carry-down symbol The determination unit 41 determines that a carry symbol has been input. The handwriting information determined to be a carry-down symbol by the carry-down symbol determination unit 41 is excluded from the handwriting information in the answer character frame, and the prepared carry symbol is displayed in the corresponding answer character frame. It can be constituted as follows. As shown in FIG. 12, the answer character frame 124-10, which is the second digit from the top of the second column of the calculation process character frame display unit 122, contains the answer information '3' previously input by the learner and the repeat information. A carry-down symbol 126 prepared in advance can be displayed in place of the handwriting information of the downward symbol. At this time, the carry-down symbol determination unit 41 sets a flag indicating that the carry-in symbol has been input by the learner in the answer character frame 124-10.
