Further, the CPU core 42 stores temporary data such as game data and flag data in the RAM 48 as the game process progresses.

  Note that the game program and data such as image data and sound data are read from the ROM 26a all at once or partially and sequentially as necessary and stored in the RAM 48.

  Each of the GPUs 52 and 54 forms part of the drawing means, and is composed of, for example, a single chip ASIC. When receiving a graphics command (drawing command) from the CPU core 42, the GPU 52 or 54 generates game image data in accordance with the graphics command. Here, the CPU core 42 gives each of the GPUs 52 and 54 an image generation program (included in the game program) necessary for generating the game image data in addition to the graphics command.

  However, data (image data such as polygons and textures) necessary for executing the graphics command is stored in the RAM 48 and acquired by the GPU 52 or 54.

  A VRAM 56 is connected to the GPU 52, and a VRAM 58 is connected to the GPU 54. The GPU 52 draws the created game image data in the VRAM 56, and the GPU 54 draws the created game image data in the VRAM 58.

  VRAMs 56 and 58 are connected to LCD controller 60. The LCD controller 60 includes a register 62. The register 62 is composed of 1 bit, for example, and stores a data value of “0” or “1” according to an instruction from the CPU core 42. When the data value of the register 62 is “0”, the LCD controller 60 outputs the game image data drawn in the VRAM 56 to the LCD 14 and outputs the game image data drawn in the VRAM 58 to the LCD 12. Further, when the data value of the register 62 is “1”, the LCD controller 60 outputs the game image data drawn in the VRAM 56 to the LCD 12 and outputs the game image data drawn in the VRAM 58 to the LCD 14.

  The operation switch 18, the touch panel 20, the right speaker 30a, and the left speaker 30b are connected to the I / F circuit 50. Here, the operation switches 18 are the above-described switches 18a, 18b, 18c, 18d, 18e, 18f, 18g, 18h, 18L and 18R. When the operation switch 18 is operated, a corresponding operation signal (operation data) is input to the CPU core 42 via the I / F circuit 50. Coordinate data detected by the touch panel 20 is also input to the CPU core 42 via the I / F circuit 50. In addition, the CPU core 42 reads out sound data necessary for the game such as BGM, sound effects, and simulated sound suppression of the character from the RAM 48 and outputs the sound data from the right speaker 30 a and the left speaker 30 b via the I / F circuit 50.

  In a state where the battle mode is selected, a radio signal is exchanged with the opponent game device through the wireless communication unit 64. That is, the wireless communication unit 64 modulates communication data for the other party into a radio signal and transmits it from an antenna (not shown), and receives a radio signal from the other party's game device via the same antenna and converts it into communication data. Demodulate.

  FIG. 3 shows an example of a memory map of the RAM 48. The RAM 48 includes a program storage area 70 for storing a program loaded from the ROM 26 a of the memory card 26.

  Although not shown, the program storage area 70 stores various programs necessary for the progress of the game, such as a program for generating / outputting game images and game sounds.

  The problem output program 72 is a program for outputting a problem from the speakers 22a and 22b. The problem may be displayed on the LCD 12. The touch-on / off detection program 74 is a program for detecting touch-on and touch-off on the touch panel 20 and turning on / off the touch-on flag according to the detection result. The touch locus temporary storage program 76 is a program for temporarily storing a touch locus (handwritten input data) from touch-on to touch-off.

  The recognition data generation program 78 is a program for generating data (recognition data) to be subjected to character recognition processing. This program prepares a plurality of types of recognition data when a plurality of strokes are input.

  The character recognition program 80 is a program for executing character recognition processing based on the recognition data generated by the recognition data generation program 78. When a plurality of types of recognition data are prepared by the recognition data generation program 78, this program performs character recognition for each of the generated plurality of types of recognition data. By adopting the recognition result having the highest recognition score among the plurality of types of recognition results thus obtained, a more accurate recognition result can be obtained.

The answer determination program 82 is a program for determining whether or not the result of the character recognition process, that is, the answer is correct. The answer display program 84 is a program for displaying an answer (input touch locus) on the LCD 14. The correct character string control program 86 is a program for reading a correct character string corresponding to a problem and selecting a recognition target character from the read correct character string. The touch trajectory control program 88 selects one or a plurality of display target strokes from the temporarily stored touch trajectories (strokes) and passes them to the answer display program 84, or one or more of the temporarily stored strokes. The RAM 48 includes a data storage area 90. The RAM 48 is a program for selecting a plurality of recognition target strokes and passing them to the recognition data generation program 78. The data storage area 90 includes a touch-on flag storage area 92, a touch locus temporary storage area 94a, a match stroke number storage area 94b, a recognition data temporary storage area 96, a recognition result temporary storage area 98, a correct character string storage area 100, and a recognition target. It has a character storage area 102, a maximum stroke number data storage area 104a, a problem data storage area 104b, a character data storage area 104c, and a recognition dictionary data storage area 106.

  The touch-on flag storage area 92 is an area for storing a touch-on flag. The touch-on flag is turned on by the touch-on / off detection program 74 when the touch-on to the touch panel 20 is detected, and is turned off when the touch-off is detected. The touch locus temporary storage area 94a is an area for temporarily storing the touch locus detected by the touch panel 20. The touch trajectory temporary storage area 94 stores a touch trajectory for the first stroke, a touch trajectory for the second stroke,. The match stroke number storage area 94b is an area for holding the number of strokes that match the character 1 (C1).

  The recognition data temporary storage area 96 is an area for temporarily storing the recognition data generated by the recognition data generation program 78. The recognition result temporary storage area 98 is an area for temporarily storing the result of character recognition processing based on the recognition data. The correct character string recording area 100 is an area for storing a correct character string corresponding to a problem.

  The recognition target character storage area 102 is an area for storing a character that is currently a target of recognition among correct character strings stored in the correct character string recording area 100. Since the recognition is performed in units of two characters, two characters (character 1 and character 2) are stored in the recognition target character storage area 102.

  In the maximum stroke number data storage area 104a, the maximum stroke at the time of handwriting for all characters (here, uppercase letters A to Z, lowercase letters a to z, and numbers 0 to 9) that can be recognized by the game apparatus 10 are stored. The number is stored. For example, since the letter “A” is usually drawn with two or three strokes, the maximum number of strokes is “3”. Similarly, since the number “1” is usually drawn with one stroke, the maximum number of strokes is “1”.

  The problem data is stored in the problem data storage area 104b. Character data storage area 104c stores uppercase letters AZ, lowercase letters az, and numbers 0-9.

  The recognition dictionary data storage area 106 is an area for storing recognition dictionary data referred to in character recognition processing. The recognition dictionary data includes characteristic data of uppercase letters A to Z, lowercase letters a to z, and numerals 0 to 9.

  In the game apparatus 10 configured as described above, the writing game proceeds as follows. Referring to FIG. 4, when a game start operation is performed via the operation switch, sound corresponding to the first problem “This is a pen.” Is output from speakers 22 a and 22 b. When the answer to the first question, that is, “THIS...” Is drawn with the stick 24 on the touch panel 20 on the lower LCD 14, the locus is detected, and the detected touch locus, that is, handwritten data is stored in the touch locus temporary storage area. Is done. The detected touch locus is displayed on the LCD 14. In addition, a character recognition process is performed on the detected touch locus, and when the detected touch locus is recognized as a correct character, the correct character is displayed on the LCD 12.

  Accordingly, as the handwriting input progresses, the correct character string “THIS...” Is additionally displayed on the LCD 12 one character at a time. On the other hand, the touch locus on the LCD 14 is recognized as a correct character, and is erased when the correct character is displayed on the LCD 12.

  As shown in FIG. 5, the character recognition process is performed in units of two consecutive characters except for the first character. In recognition of “THIS...”, First, the first character “T” is set in a predetermined area (register C 1) of the recognition target character storage area 102. Then, it is determined whether or not the touch locus stored in the touch locus temporary storage area 94 matches the character in the register C1.

  After the first recognition process, the next recognition target character “H” is set in the register C2. Then, it is determined whether or not the touch locus stored in the touch locus temporary storage area 94 matches the character in the register C2.

  When the character “H” is recognized in the second recognition process, the recognition target is shifted backward by one character, that is, “H” and “I” are set in C1 and C2, respectively. Then, it is determined whether or not the touch trajectory data stored in the touch trajectory data storage area matches the character “I” in the register C2.

  Thereafter, the same recognition process is repeated until the end character “N” is recognized. Accordingly, a total of 10 recognition processes are executed for the character string “THIS IS A PEN” composed of 10 characters.

  Hereinafter, a specific example of the recognition process will be described. First, the recognition processing corresponding to the character string “THIS” will be described with reference to FIGS. 6 (A), 6 (B), 7 (A), and 7 (B). It is assumed that no erroneous input or timeout occurs. Referring to FIG. 6A, the first recognition process is targeted for the first character, that is, “T”. “T” is held in the register C1. The maximum number of strokes for “T” is “2”.

  When the first touch locus is detected, that is, when the first stroke (S0) is input, a recognition process is performed to determine whether or not the first stroke matches the C1 character “T”. X).

  When the second stroke (S1) is input, a recognition process is executed to determine whether or not the first stroke and the second stroke match the C1 character “T”, and it is determined that they match (O). As a result, “T” is displayed on the LCD 12. At this time, the number of strokes determined to match “T” (= 2) is held in the register M0 in the match stroke number storage area 94b. The number of match strokes is used in connection with continuous recognition (described later).

  Referring to FIG. 6B, the first recognition process is targeted for the second recognition process. Accordingly, “T” and “H” are set in the registers C1 and C2, respectively. The maximum stroke numbers of the characters “T” and “H” are “2” and “3”. This is described below as a recognition target character (T, H) and a maximum stroke number (2, 3). The total maximum number of strokes of the characters (T, H) is “5”.

  When the third stroke (S2) is input, a recognition process for determining whether or not the third stroke matches the C2 character “H” is executed, and it is determined that there is a mismatch. At this time, the first to third strokes are temporarily held in the areas S0 to S2 (see FIG. 3) in the touch-off locus storage area 94a. The temporary holding stroke number (= 3) does not exceed the total maximum stroke number (= 5) of the characters “T” and “H”, but exceeds the maximum stroke number (= 2) of the character “T”. The first and second strokes are considered to match the letter “T”. For this reason, continuous recognition (described later) is not performed.

  When the fourth stroke (S3) is input, the same recognition process is executed for the third stroke and the fourth stroke, and it is also determined that there is a mismatch here. When the fifth stroke (S4) is input, the same recognition process is executed for the third stroke, the fourth stroke, and the fifth stroke, and it is determined that they match. As a result, “H” is further displayed on the LCD 12. “3” is held in the register M0.

  Referring to FIG. 7A, in the third recognition process, the recognition target is shifted backward by one character. Accordingly, “H” and “I” are set in the registers C1 and C2. Of the first to fifth strokes temporarily held in the regions S0 to S4, the first and second strokes corresponding to the character “T” are discarded, and the third to fifth strokes are shifted to the regions S0 to S2. As a result, the third to fifth strokes become the first to third strokes, and the next input stroke becomes the fourth stroke (S3). The maximum number of strokes of the character (H, I) is (3, 3), and the total maximum number of strokes is “6”.

  When the fourth stroke is input, a recognition process for determining whether or not it matches the C2 character “I” is executed, and it is determined that there is a mismatch. At this time, the temporary holding stroke number (= 4) does not exceed the total maximum stroke number (= 6) of the characters “H” and “I”, but the maximum stroke number (= 3) of the character “H”. Since it has exceeded, it is considered that the first to third strokes coincide with the letter “H”, and continuation recognition (described later) is not performed.

  When the fifth stroke is input, the same recognition process is executed for the fourth stroke and the fifth stroke, and it is determined that they match. Note that the determination is made not only for uppercase letters but also for lowercase letters. Here, it is determined that lowercase letters “i” match. As a result, the correct character “I” is further displayed on the LCD 12.

  Referring to FIG. 7B, in the fourth recognition process, “I” and “S” are set in registers C1 and C2. Of the first to fifth strokes, the first to third strokes corresponding to the character “H” are discarded, and the fourth and fifth strokes are shifted to the areas S0 and S1. As a result, the fourth and fifth strokes become the first and second strokes, and the next input stroke becomes the third stroke (S2). “2” is held in the register M0. The maximum number of strokes of the character (I, S) is (3, 1), and the total maximum number of strokes is “4”.

  When the third stroke is input, a recognition process is performed to determine whether the third stroke matches the C2 character “S”, and it is determined that the third stroke does not match. At this time, the temporary holding stroke number (= 3) does not exceed the total maximum stroke number (= 4) of the characters “I” and “S”, and the maximum stroke number (= 3) of the character “I” is also Since it does not exceed, continuous recognition is performed.

  In the continuous recognition, first, a recognition process is performed to determine whether or not the first to third strokes match the C1 character “I”, and it is determined that they match. Thereby, the third stroke is determined to be a part of “I”. “3” is held in the register M1.

  Next, when the fourth stroke is input, a recognition process is executed to determine whether or not the fourth stroke matches the C2 character “S”, and it is determined that they match. In addition, a recognition process is performed to determine whether or not the fourth and third strokes match the C2 character “S”, and it is determined that they do not match. As a result, the correct character “S” is further displayed on the LCD 12. These two determinations are based on the values held in the registers M0 and M1. That is, the recognition for the fourth stroke (S3) is first performed based on the holding value “3” of M0, and the recognition for the fourth and third strokes (S3 and S2) is further performed based on the holding value “2” of M1. Done. However, if the recognition based on M0 is recognized as a C2 character, the subsequent recognition based on M1 may not be performed.

  Thereafter, “S” and “A” are set in the registers C1 and C2, and the same processing is performed.

  Next, character recognition processing when an erroneous input occurs will be described with reference to FIGS. 8 (A) to 8 (C) and FIG. Referring to FIG. 8A, it is assumed that “TAI...” Is input to the correct character string “THI. Referring to FIG. 8B, the first character “T” is recognized in the same manner as “T” in FIG. Referring to FIG. 8C, the maximum number of strokes of the recognition target character (T, H) is (2, 3), and the total maximum number of strokes is “5”. When the third stroke is input, the third stroke is collated with the C2 character “H”, and it is determined that there is a mismatch. When the fourth stroke is input, the fourth and third strokes are collated with the C2 character “H”, and are determined to be inconsistent. When the fifth stroke is input, the fifth to third strokes are collated with the C2 character “H”, and are determined to be inconsistent. At this time, since the number of temporary holding strokes has reached the total maximum number of strokes, it is indicated by a cross mark (×) that it is an erroneous input.

  Subsequently, referring to FIG. 9, since the C1 character “T” is correct and the C2 character “H” is incorrect, collation is started with the character “H” as C1. On the other hand, since the player has found that “A” is incorrect, the player inputs “H...”. When the first stroke is input, the first stroke is collated with the C1 character “H”, and it is determined that there is a mismatch. When the second stroke is input, the second and first strokes are collated with the C1 character “H”, and are determined to be inconsistent. When the third stroke is input, the third to first strokes are collated with the C1 character “H”, and are determined to match. In this way, “H” is recognized. Thereafter, the same processing is repeated.

  Next, character recognition processing when a timeout occurs will be described with reference to FIGS. 10 (A) to 10 (C). Referring to FIG. 10A, it is assumed that a time-out occurs after “I” of “IAM...” Is input. Referring to FIG. 10B, the first character “I” is recognized when the second stroke is input. Referring to FIG. 10C, the third stroke is determined to be a part of “I” instead of “A” by the continuous recognition as in the case of FIG. 7B. Then, after the last third stroke is touched off, a time-out is determined if the no-input state continues for a certain period of time. In this case, since it is determined that the last third stroke is a part of “I”, there is no erroneous input stroke and no error is displayed. After the time-out, the process proceeds to recognition of the next character “A”.

  Next, a character recognition process when a timeout occurs at the time of erroneous input will be described with reference to FIGS. 11 (A) to 11 (C). Referring to FIG. 11A, it is assumed that a timeout has occurred while inputting “ILM...” For correct character string “IAM. Referring to FIG. 11B, the first character “I” is recognized when the second stroke is input. At this time, “2” is held in the register M0. Referring to FIG. 11C, the third stroke is determined to be a part of “I” instead of “A” by the continuous recognition as in the case of FIG. 7B. At this time, “3” is held in the register M1.

  Subsequently, when the fourth stroke is input, it is determined whether or not it matches “A”, and it is determined that they do not match. Further, it is further determined whether or not the fourth and third strokes coincide with “A”, and it is also determined that they do not coincide with each other. These two determinations are also based on the values held in the registers M0 and M1, as in the case of FIG. 7B.

  If the no-input state continues for a certain period after the last fourth stroke is touched off, it is determined that a timeout has occurred. In this case, it is determined that the first to third strokes are “I”, and the last fourth stroke does not match “A”, so that it is determined as an erroneous input stroke and an error display is performed. After the time-out, the process proceeds to recognition of the next character “A”.

  When playing the game as described above, the CPU core 42 executes processing according to the flowcharts of FIGS. Referring to FIG. 12, the problem is first output from speakers 30a and 30b in step S1. In the subsequent step S3, the first character of the alphanumeric character string corresponding to the output problem is set in the variable C1. The variables C1 and C2 are stored in the recognition target character storage area 102 (see FIG. 3). In step S5, “0” is set to the variable nS, and “0” is set to the variable nM. After setting, the process proceeds to step S7.

  Here, the variable nS means the number of strokes temporarily stored in the touch locus temporary storage area 94a (the number of elements in the stroke array). On the other hand, the variable nM means the number of strokes that match the variable C1. Therefore, assuming that three strokes are temporarily stored and two of them match the C1 character, nS = 3 and nM = 2.

  In step S7, it is determined whether or not there is a stroke input. If NO, it is further determined in step S9 whether or not a fixed time has elapsed since the last touch-off. If there is no input to the touch panel 20, that is, no input state continues for a certain time or longer, YES is determined in step S 9, and the process proceeds to step S 11 to determine whether or not the variable nS is greater than zero. If “NO” here, the process returns to the step S7, and if “YES”, the process proceeds to the step S21. In step S21, it is notified that the input is incorrect. The notification is performed, for example, by displaying a cross (x) on the LCD 14 (see FIG. 9). After the notification, the process returns to step S5.

  If a touch locus is detected by the touch panel 20, YES is determined in a step S7, and the process proceeds to a step S13. In step S13, the detected touch locus, that is, the input stroke is stored in the region S [nS], and the variable nS is incremented. Here, the region S [nS] corresponds to any one of the regions S0, S1,... Included in the touch locus storage temporary storage region 94a (see FIG. 3). Therefore, for example, the first detected touch locus, that is, the first stroke is held in the region S0, and the next second stroke is held in the region S1.

  In the next step S15, recognition processing is executed for the region S [0 to (nS-1)]. In step S17, it is determined whether or not the recognition result matches the variable C1. If YES, the process proceeds to step S23. Therefore, for example, when the first stroke is input, the first stroke is collated with the correct character of the variable C1. If the second stroke is input without matching here, the first stroke and the second stroke are collated with C1 (see FIG. 6A).

  If “NO” in the step S17, it is determined whether or not the variable nS is equal to or larger than the variable MAX (C1) in a step S19. If “NO” here, the process returns to the step S7. On the other hand, if YES, after notifying an error in step S21, the process returns to step S5. Here, the variable MAX (C1) indicates the maximum number of strokes of the correct character set in the variable C1. The maximum stroke number data describing the maximum stroke number for each character is stored in the maximum stroke number data storage area 104a. Therefore, when the number of strokes temporarily stored reaches the maximum number of correct characters, if the stroke in the area [0 to (nS-1)] does not match the character in the variable C1, the stroke is erroneous. It is considered as input and re-input is accepted.

  Referring to FIG. 13, in step S23, variable C1 is displayed on LCD 12 as a correct answer. In the subsequent step S25, it is determined whether or not the variable C1 is the last character of the question character string. If YES, the problem recognition process is terminated. If “NO” in the step S25, the next character is set in the variable C2 in a step S27, and further, the variable nS is held in the region M [nM] and the variable nM is incremented in a step S29. Here, the area M [nM] corresponds to any one of the areas M0, M1,... Included in the match stroke number storage area 94b (see FIG. 3).

  In the following step S31, it is determined whether or not there is a stroke input. If YES here, the process proceeds to step 41. On the other hand, if NO, it is further determined in step S33 whether or not a fixed time has elapsed since the last touch-off. If the no-input state continues for a certain time or more, YES is determined in step S33, and the process proceeds to step S35. In step S35, whether or not the variable nS matches the holding number of the region M [nM-1], that is, whether or not the number of strokes temporarily stored matches the number of strokes determined to be C1 match. Is determined.

  If “NO” here, the process proceeds to a step S37 to notify that the input stroke after the stroke determined to match the C1 is an erroneous input (see FIG. 11C). After the notification, the process proceeds to step S39. If “YES” in the step S35, the process immediately proceeds to a step S39.

  In step S39, the value of variable C2 is set to variable C1. That is, the value of the variable C1 is overwritten by the value of the variable C2. After setting, the process returns to step S5.

  Referring to FIG. 14, in step S41, the input stroke is held in region S [nS], and variable nS is incremented. In the subsequent step S43, a value obtained by subtracting “1” from the variable nM is set in the variable a, and in a step S45, it is determined whether or not the variable a is “0” or more. If “YES” in the step S45, the process proceeds to a step S47. If “NO” in the step S45, the process proceeds to a step S53 (described later).

  In step S47, character recognition processing is executed for the region S [M [a] to (nS-1)]. In step S49, it is determined whether or not the recognition result matches the variable C2. If YES, the process proceeds to step S51. In step S51, the content held in the area S [M [a] to (nS-1)] is shifted to the area S [0 to (nS-M [a] -1)], and the variable nS is changed to the area M (a). As a new variable nS, the variable nM is set to “0”, and the value of the variable C2 is set to the variable C1. As a result, the recognition target is shifted backward by one character in the problem character string. After setting, the process returns to step S23.

  If “NO” in the step S49, the process shifts to a step S50 to decrement the variable “a”, and then returns to the step S45.

  If “NO” in the step S45, the process shifts to a step S53 to determine whether or not the relational expression “nS ≧ MAX (C1) + MAX (C2)” is satisfied, and if “YES” here, the process shifts to a step S37. If “NO” in the step S53, it is further determined whether or not the relational expression “nS ≧ MAX (C1)” is satisfied in a step S55, and if “YES” here, the process proceeds to a step S31.

  If “NO” in the step S55, a character recognition process is executed on the region S [0 to (nS−1)] in a step S57. In step S59, it is determined whether or not the recognition result matches the variable C1. If YES, the process proceeds to step S29. If “NO” in the step S59, the process proceeds to a step S31.

  Therefore, when the temporary holding stroke number exceeds the total maximum stroke number of the C1 character and the C2 character, it is notified that the input stroke after the C1 match stroke is incorrect (see FIGS. 8C and 9). Although the temporary holding stroke number does not exceed the total maximum stroke number, if the C1 character exceeds the maximum stroke number, the stroke input is continuously accepted. Until the number of temporary holding strokes reaches the maximum number of strokes of the C1 character, the recognition process is executed for all temporary holding strokes. Then, when the process waits for a stroke input and the next stroke is accepted, the process of recognizing the region S [M [a] to (nS-1)] while decrementing the value of the variable a is repeatedly executed. In the example of FIG. 7B, when the fourth stroke is input, since a = 1, first recognition processing is executed with a = 1, and then second recognition processing is executed with a = 0. Is done.

  As is apparent from the above, in this embodiment, the CPU core 42 outputs a problem whose correct answer is known in advance (S1), and performs a handwritten character input operation related to the output problem in units of strokes through the touch panel 20. Accept (S7, S31). A recognition process is performed at each reception (S15, S47, S57), and it is determined whether or not the result of the recognition process performed matches the correct character (S17, S49, S59). If the determination result is negative, it is further determined whether or not the number of strokes of the accepted handwritten character input operation exceeds the maximum number of strokes of the correct character (S19, S53, S55), and this determination result is positive If the answer is correct, an incorrect answer is notified (S21, S37).

  In this way, when the handwritten character input operation is accepted in units of strokes and recognition processing is performed each time it is received, and the result of the recognition processing does not match the correct character, the number of strokes of the accepted handwritten character input operation is the maximum number of correct characters. It is determined whether or not the number of strokes is exceeded, and an incorrect answer is notified when the determination result is affirmative, so that an incorrect answer can be notified at an early timing. As a result, the waiting time is shortened and effective learning can be performed.

  The correct character includes a first correct character and a second correct character that follows the first correct character. In the correct answer determination, first, it is determined whether or not the result of the recognition process performed matches the first correct character (first determination process: S17), and then the result of the first determination process is positive. After that, it is determined whether or not the result of the recognition process performed in the recognition step matches the second correct character (second determination process: S49). Then, when the result of the second determination process is negative, the result of the recognition process (the “rear” recognition result) performed after the result of the first determination process becomes affirmative matches the first correct character. It is discriminate | determined whether to perform (3rd discrimination | determination process: S59).

  Thus, after executing the first and second determination processes, if the number of strokes of the accepted handwritten character input operation is less than or equal to the maximum number of strokes of the first correct character, the third determination process is further executed. 2. If the stroke that is the object of the discrimination process is a part of the first correct character, it is known. As a result, the accuracy of determining whether or not the handwritten input character matches the correct character is increased, and accordingly, the incorrect answer notification timing is advanced.

  Furthermore, when the third determination process is executed, at least a part of the stroke determined to match the first correct character and a stroke input after the stroke determined to match the first correct character are included. The stroke is recognized by the recognition step, and it is further determined whether or not the result of the recognition process matches the second correct character (fourth determination process).

  As described above, by performing the fourth determination process together with the third determination process, it is possible to know that the stroke that is a part of the first correct character is a part of the second correct character. As a result, the accuracy of determining whether or not the handwritten input character matches with the correct character as to whether or not the handwritten input character matches with the correct character is further increased, and the incorrect notification timing is further advanced.

  In the above description, the writing game that writes out the English text output from the speaker 22a or the like has been described. However, the present invention outputs a problem in which the correct answer is known in advance, and inputs handwritten characters related to the output problem. Learning support that accepts operations through the touch panel, recognizes handwritten characters corresponding to the accepted input operations, determines whether or not the recognized characters are correct, and informs the user by learning the determination results Applicable to the program. Further, the present invention is not limited to the learning support program, and can be applied to a character recognition program that accepts a handwritten character input operation through a touch panel and recognizes a handwritten character corresponding to the accepted input operation.
