Description

  The present invention relates to a written kanji determination system and a written kanji determination program, and in particular, correctly writes a plurality of kanji distributed for each grade of an elementary school in accordance with the course of study for writing, stroke order, and writing. The present invention relates to a written kanji determination system and a written kanji determination program.

  Kanji learning instruction is given to help children learn kanji in elementary school language and transcription classes. Here, kanji learning is aimed at writing with attention to how to assemble the characters, writing the characters in the correct stroke order (character shape), paying attention to the size of the characters and the balance of each stroke. Is stipulated in the Course of Study, and teachers provide guidance in line with such purposes. At this time, various learning materials are used in order for the children to learn kanji. For example, a sub-textbook such as a so-called “kanji drill” is used to repeatedly write the target kanji multiple times. Is mainly used.

  “Kanji Drill” learns sample Kanji as examples, kanji for learning stroke order by distinguishing the stroke order by numbers and colors, etc., or strokes such as stroke shapes and brush strokes as a child traces from above Therefore, a plurality of practice kanji characters shown in light gray are displayed. In addition, normal squares without crosshairs are also prepared for easy-to-balance the character shape by dividing the inside of the square for writing Chinese characters with crosshairs. Necessary information depending on the progress of learning The child can learn kanji while checking.

  However, in the above-described kanji learning, the following problems may occur. That is, in the case of a Japanese language class or the like, since one teacher is responsible for a plurality of children, it is difficult to confirm all how accurately each child wrote kanji. Even if the stroke order is wrong, if the shape and balance of the kanji written in the square, such as the kanji drill, are correct, the wrong stroke order cannot be pointed out. I remembered it. In addition, when learning kanji using a kanji drill, children do not pay attention to the necessary information (sample kanji, etc.) that is provided as appropriate. There was a thing. In other words, there has been little development of a system or technology for accurately grasping the situation in the middle of the writing operation, such as kanji strokes and stroke order, and determining whether or not correct writing is being performed.

  On the other hand, with the development of computer technology in recent years, dramatic progress has been made in character input technology and handwritten character recognition technology. However, in these, especially handwritten character recognition technology and the like are mainly provided for elderly people who are not good at direct input from a keyboard or the like, and for inputting each character to a computer simply and efficiently. However, it did not require a determination process as to whether or not to write kanji correctly. That is, handwritten character recognition technology, etc. is generally used to determine which kanji is similar to the character shape written on the touch panel screen, and to display a plurality of kanji characters that are candidates for character input on the screen. Met. Therefore, even if it is correct that one stroke (for example, a horizontal stroke) constituting a kanji font is written horizontally from “left to right”, “right to left” or “left to right, Even when the writing is different from the correct stroke, as in “Left”, it may be determined as the correct writing if the final shape is the same.

  Accordingly, in view of the above circumstances, the present invention has an object to provide a writing kanji determination system and a writing kanji determination program that can be applied to learning kanji for children by determining whether or not the kanji is correctly written. is there.

In order to solve the above problem, the written kanji determination system of the present invention is a written kanji determination system for determining the writing accuracy of a written kanji written on a touch panel screen of a determination terminal, wherein the determination terminal includes: Stroke data relating to the total number of strokes constituting the kanji font, stroke order data relating to the stroke order of the strokes, stroke shape data defining the reference stroke shape of the strokes, writing start coordinates and writing end coordinates of the strokes, and the strokes Kanji information including position data that defines the relative position relationship with a written stroke that has already been written in the previous stroke order, and stroke data that defines the stroke condition indicating the stroke of the stroke. Recognizing kanji information storage means stored corresponding to each kanji and the start and end of writing of the stroke on the touch panel screen and counting the number of strokes Whether the written kanji is correctly written based on the written data receiving means for receiving input of written data for each stroke written on the touch panel screen, and the kanji information corresponding to the written data and the written kanji Stroke number determining means for determining whether the counted stroke number of the written kanji matches the total stroke number of the stroke number data, and a stroke order for determining whether the stroke order of the stroke matches the stroke order of the stroke order data. Determination means, stroke shape determination means for determining whether the stroke shape of the stroke matches the reference stroke shape of the stroke shape data, at least one of the stroke start coordinates and the stroke end coordinates of the stroke is the position data A stroke position determining means for determining whether or not the stroke position condition is matched, and determining whether or not the stroke stroke of the stroke matches the stroke condition of the stroke data A writing determination means including a handwriting determination means, and a display control means for displaying on the touch panel screen the written strokes and the determination result determined by the writing determination means. The determination of the stroke determination OK or the stroke determination NG is performed as a determination result for each writing of the one stroke, and the writing of the next stroke is performed only when the determination result for each stroke of the stroke is the stroke determination OK. The display control means is configured to display the determination result on the touch panel screen for each writing of the stroke.

  Here, the determination terminal includes a touch panel screen with a touch panel function on a display unit such as a liquid crystal display, and moves a finger or a touch pen along the touch panel screen, or moves the finger on the touch panel screen to the finger or touch pen. It is a kind of information terminal that can perform various operations by tapping (tapping) with a flat tablet terminal (slate terminal), notebook computers with touch panel screens, and schools and companies. The so-called “electronic blackboard (interactive board)” can be exemplified. Here, by using a touch panel screen such as a tablet terminal or a notebook computer, the child can learn kanji while using the sense of touch and vision, and has the advantage that the kanji can be acquired quickly. . In particular, the tablet terminal has a display screen of about 7 inches to 10 inches and can be easily learned even by a child or the like, and is particularly suitable when an individual child learns kanji. is there. On the other hand, an electronic blackboard is installed in front of a classroom or the like, and a teacher can easily teach kanji to a plurality of children by using a display screen larger than a tablet terminal or a notebook computer.

  The kanji information storage means stores the written kanji input via the touch panel screen for each stroke, and determines the number of strokes, stroke order, stroke shape, relative positional relationship between the strokes, and strokes. Is stored as kanji information. The data stored in the kanji information and the writing determination based on the data will be described. For example, the stroke number data is stored in advance for each kanji with respect to the total stroke number of the kanji, and the stroke number determination means accepts writing data input. The accuracy of writing is judged by comparing with the number of strokes counted by the means. In other words, when the total number of strokes is “half” and the horizontal stroke is mistakenly written with three strokes, or when the first stroke and the second stroke are written continuously, the number of strokes is insufficient. Is determined as an incorrect writing. That is, when writing Chinese characters, if the number of strokes is not correct, there will be extra or insufficient strokes, and the writing accuracy itself will be lacking.

  On the other hand, the stroke order data stores the stroke order of each stroke, and is used by the stroke order determining means to determine whether the strokes that have been written are written in the correct order. For example, in the case of “half”, it is possible to determine the case where the center vertical image should be written on the fifth stroke, and the center vertical image is erroneously written on the third stroke. In addition, the stroke shape data is determined by the stroke shape determination means to match the reference stroke shape defined for each stroke in order to determine the character shape (dots, horizontal strokes, vertical strokes, oblique strokes) of each stroke. It is used to do.

  The position data is used for determining the relative positional relationship with the already-written handwriting by the handwriting position determining means based on the handwriting start coordinates and the handwriting end coordinates on the touch panel screen of each handwriting. For the first stroke, since there is no written stroke, the processing by the stroke position determining means is omitted. In addition, the stroke data is related to strokes such as “Tome”, “Splash (left splash, right splash)”, “Harai (left peel, right peel)”, “I”, etc. The stroke condition is defined, and is determined by the stroke determination means. That is, even when the writing start coordinates and the writing end coordinates meet the conditions by the above-described drawing position determination means, for example, when the vertical image is continuously changed from the vertical image to the horizontal image, as in the second drawing of “mountain”, for example. It is possible to determine a case where the change point is “I” and is not written.

  Therefore, according to the written kanji determination system of the present invention, the number of strokes, the stroke order, and the relative positional relationship for each stroke for each stroke of the kanji to be acquired based on various data included in the previously stored kanji information. The shape of the stroke and the stroke are determined, and it is determined whether or not the writing is correctly performed, and the determination result can be obtained.

  In addition to the above configuration, the writing kanji determination system according to the present invention may further include: “The writing data receiving means predefines writing coordinates detected by moving on the touch panel screen according to the writing operation of the stroke. A writing coordinate detecting means for detecting each unit time, and a distance direction for calculating a moving distance and a moving direction on the touch panel screen between the writing end coordinates and the writing coordinates detected immediately before the writing end coordinates. The stroke determination unit may further include a distance direction determination unit that determines the stroke of the stroke based on the calculated movement distance and the movement direction. .

  Therefore, according to the writing kanji determination system of the present invention, each writing coordinate for each predetermined unit time of a stroke drawn on the touch panel screen is detected, and the writing coordinate immediately before the writing end coordinate and the writing end coordinate are detected. The movement distance and direction are obtained to determine the accuracy of the stroke. For example, “Harai” and “Hane”, which are types of brush strokes, require a finger or a touch pen to be moved quickly on the touch panel screen, and the movement distance per unit time tends to increase. On the other hand, “Tome” or the like has a strong tendency that the moving distance per unit time becomes small. Therefore, by calculating the movement distance from the writing coordinates immediately before the writing end coordinates, it is possible to determine whether the last part of the stroke is "Hara" or "Splash" or "Stop". Become. At this time, since the moving direction is also calculated from the two coordinates, it is possible to determine the stroke by including information related to the direction.

  Furthermore, the writing kanji determination system according to the present invention has, in addition to the above configuration, “intersection determination in which the stroke position determination means determines the number of intersections and types of intersections between the strokes based on the position data. "Means" may be provided.

  Therefore, according to the written kanji determination system of the present invention, the number of intersections and the type of intersection between the written writings are determined. Here, in the strokes constituting the kanji, there may be “intersections” that intersect or overlap each other. Here, the “intersection point” can be defined as at least two strokes intersecting each other or intersecting each other and one stroke does not protrude from the other stroke. ) Are classified in detail: 1) A type in which the vertical and horizontal images intersect with a cross (eg, “ten”), and 2) The vertical image does not protrude upward or does not protrude downward relative to the horizontal image. 3) Crossing type (for example, “Up”, “Down”), 3) Diagonal image intersects with vertical or horizontal image (for example, “Right”, “Left”, “Year”, etc.) 4) It is known that a diagonal image intersects a vertical image or a horizontal image without passing through (for example, “sword”). By determining the number of intersections and the type of the intersection by the intersection determination means, it is possible to accurately determine the writing accuracy. Note that the intersection determination means is also subject to determination even when a case where the intersection does not intersect as an intersection (eg, a “dog” point) intersects a horizontal image or the like.

On the other hand, the writing kanji determination program of the present invention includes the following: “stroke data relating to the total number of strokes constituting a kanji font, stroke order data relating to the stroke order of the strokes, stroke shape data defining the reference stroke shape of the strokes, Indicates the position data specifying the stroke position condition indicating the relative positional relationship between the stroke start coordinate and stroke end coordinate of the stroke stroke and the stroke stroke already written in the stroke order before the stroke stroke, and indicates the stroke of the stroke stroke. Recognizing kanji information storage means that stores kanji information including stroke data that defines the stroke conditions corresponding to each kanji, recognizing writing start and end of writing on the touch panel screen, counting the number of strokes, and Written data receiving means for receiving input of written data for each stroke written on a touch panel screen, the written data, and the Chinese corresponding to the written Chinese character Stroke number determining means for determining whether the number of strokes of the written kanji counted to determine whether the written kanji is correctly written based on the information matches the total number of strokes of the stroke number data, and the stroke order of the strokes Stroke order determining means for determining whether the stroke order matches the stroke order of the stroke order data, stroke shape determining means for determining whether the stroke shape of the stroke matches the reference character shape of the stroke shape data, and the writing of the stroke A stroke position determining means for determining whether at least one of a start coordinate and a writing end coordinate matches the stroke position condition of the position data; and whether the stroke of the stroke matches the stroke condition of the stroke data. determining a stroke determination unit performs determination of the stroke determination OK or stroke determination NG as the determination result for each writing of one of the stroke, the determination for each writing of one of the artist's brush Writing determination means which result to be able to writing the observed following the stroke when the artist's brush determination OK, and writing already the stroke on the touch panel screen, the determined by the written input determination unit for each writing of one of the stroke the determination result as a display control means for displaying, to function determination terminal "mainly composed of those were. Furthermore, in addition to the above-described configuration, “writing coordinate detection means for detecting writing coordinates detected by moving on the touch panel screen in accordance with the writing operation of the stroke for each predetermined unit time, and the writing end The writing data receiving means comprising: a distance direction calculating means for calculating a moving distance and a moving direction on the touch panel screen between the coordinates and the writing coordinates detected immediately before the writing end coordinates; and the calculated movement As the stroke determination unit including a distance direction determination unit that determines the stroke of the stroke based on the distance and the moving direction, the determination terminal is made to function ”or“ the strokes of each other based on the position data. `` Make the determination terminal function as the stroke position determination means including the intersection determination means for determining the number of intersections and the type of intersection '' But it may be in.

  Therefore, according to the writing / kanji determination program of the present invention, by installing the program in the determination terminal, the determination terminal can achieve the effects of the writing / kanji determination system.

  Hereinafter, the written kanji determination system 1 (hereinafter simply referred to as “determination system 1”) and the written kanji determination program 2 (hereinafter simply referred to as “determination program 2”) of the present embodiment will be described with reference to FIGS. I will explain. Here, the determination system 1 according to the present embodiment is used when learning kanji in Japanese at an elementary school, and determines whether a plurality of kanji to be taken in each grade is correctly written.

  As shown in FIG. 1, the determination system 1 of the present embodiment is mainly composed of a tablet terminal 3, and exhibits a writing accuracy determination function by starting a determination program 2 stored in a terminal storage device 32. The touch panel screen 4 having input and display functions is provided on the front surface of the housing. Here, the tablet terminal 3 corresponds to the determination terminal of the present invention. The tablet terminal 3 has, as its functional configuration, stroke number data 11 relating to the total number of strokes constituting the kanji font, stroke order data 12 indicating the stroke order of each stroke, and stroke shape data 13 defining the stroke reference character shape. , Position data 14 that defines a stroke position condition indicating the relative positional relationship of a plurality of strokes, and stroke data 15 that defines strokes such as “Splash”, “Harai”, and “Tome” of strokes. Kanji information storage means 17 storing the kanji information 16 corresponding to a plurality of registered kanji characters, and writing data receiving means 19 for detecting writing operations on the touch panel screen 4 and receiving input of writing data 18 for each stroke. On the basis of the received writing data 18 and the kanji information 16 corresponding to the writing kanji 5, the written kanji 5 is correctly written according to various judgment criteria. It is mainly configured by including a determining writing determination means 20 Luke.

  Here, more specifically, the writing determination means 20 counts the number of accepted writing data 18 and determines whether or not the stroke number of the stroke and the total stroke number defined in the stroke number data 11 match. Means 21, stroke order determining means 22 for determining whether or not the stroke order of the strokes matches the stroke order data 12, and stroke shape determining means 23 for determining whether or not the stroke shape of the strokes matches the reference character shape of the stroke shape data 13. The stroke position determining means 24 for determining the relative positional relationship between a plurality of strokes based on the position data 14, and the stroke determining means 25 for determining the stroke of the stroke based on the stroke data 15. . Here, in the handwritten data 18 received for each stroke, the number of strokes, the stroke order, the stroke position, and the information related to the stroke count of the stroke based on the writing operation detected by the touch panel screen 4 in order to perform the determination related to the stroke, Information on the movement trajectory of the writing operation, information on the stroke shape specified based on the movement trajectory, and information on the stroke based on the movement trajectory and the stroke shape are included.

  Furthermore, the writing data receiving means 19 uses a finger or a touch pen that moves on the touch panel screen 4 in accordance with the detected writing operation as a writing start coordinate P1 at which the writing operation is started, every predetermined unit time. The writing coordinate P2 that detects the coordinate position of the finger or the like during the writing operation, and the writing end coordinate P3 that ends the writing operation and releases the finger or the like from the touch panel screen 4 are detected, and information about each coordinate is included in the writing data 18 And a distance / direction calculating means 27 for calculating a movement distance L and a movement direction D between the writing end coordinates P3 and the writing coordinates P2 ′ detected immediately before the coordinates (3) ( (See FIG. 5). In addition, the stroke determination unit 25 determines whether the stroke of the writing data 18 accurately writes a stroke such as “Splash” or “Harai” based on the calculated movement distance L and movement direction D. The direction determining means 28 is included. Further, the stroke position determining means 24 is an intersection determining means 29 for determining the number of intersections C at which the strokes intersect and the type of the intersection C based on the position data 14 in which the relative position conditions between the strokes are defined. It is comprised including.

  As another functional configuration, the tablet terminal 3 is provided on the touch panel screen 4 and a display control means 30 for displaying a written stroke on the touch panel screen 4 based on the accepted writing data 18. It mainly comprises an input control means 31 for operating the tablet terminal 3 in accordance with a change or a capacitance change. Further, the kanji information storage means 17 is stored in the terminal storage device 32 of the tablet terminal 3. Further, the terminal storage device 32 includes the above-mentioned writing data 18, current information 34 (details will be described later), distance data 35 and direction data 36 relating to the movement distance L and the movement direction D calculated by the distance direction calculation means 27, respectively. And determination result data 33 comprehensively determined based on the result of each determination process. Here, the writing data 18, the current information 34, the distance data 35, the direction data 36, and the determination result data 33 are temporarily stored in the determination process for the written kanji 5, and the end of the determination process is as follows. It may be deleted from the terminal storage device 32 at the same time. If it is determined based on the determination result data 33 that the writing is correct for the written kanji 5, the passed kanji information 37 for the written kanji is stored in the terminal storage device 32 and already cleared. May be displayed on the touch panel screen 4 or the like. The determination program 2 of the present invention is installed in the terminal storage device 32 and can be activated by an activation operation using the touch panel screen 4. Furthermore, the tablet terminal 3 can adopt a well-known hardware configuration. In addition to the touch panel screen 4 and the terminal storage device 32 configured by a hard disk drive or semiconductor memory, the tablet terminal 3 includes a stroke determination unit 20 and the like. It comprises a CPU for performing various determination processes and a data input / output device for storing various information and data in the terminal storage device 32 or outputting them to the outside, or a wireless communication device capable of wireless communication. Yes.

  Next, an example of the determination process of the written kanji 5 using the tablet terminal 3 by the determination system 1 of the present embodiment will be described mainly based on the flowcharts of FIGS. 2 to 4 and the explanatory diagram of FIG. Here, as the determination system 1 of the present embodiment, an example in which “half” having a total number of strokes of five strokes is determined as a written kanji 5 will be described. Here, the circled numbers shown in FIG. 5A indicate the stroke order of “half”. Further, in “half”, the horizontal images of the third and fourth strokes intersect with the vertical image of the fifth stroke, respectively, and have two intersections C. In the following, the first stroke of “half” is the first stroke F1, the second stroke is the second stroke F2, the third stroke is the third stroke F3, and the fourth stroke is the fourth stroke. F4 and the fifth stroke will be described as a fifth stroke F5.

  First, the determination program 2 stored in the terminal storage device 32 is activated (step S1), and the determination process of the written kanji 5 by the tablet terminal 3 is made possible. Then, by selecting and extracting kanji information 16 corresponding to “half”, which is the writing kanji 5 to be determined, from the plurality of kanji information 16 stored in the kanji information storage means 17, the touch panel screen 4 performs the operation. The Chinese character information 16 is received and read into a temporary memory (not shown) (step S2). Thereby, the stroke number data 11, the stroke order data 12, the stroke shape data 13, the position data 14, and the stroke data 15 relating to “half” of the Chinese character information 16 are prepared, and a determination process based on these is possible.

  Next, current information 34 including which stroke has already been written at the current stage and the determination result for the stroke is obtained from the terminal storage device 32 (step S3). Here, the current information 34 is a cumulative storage of information on written strokes that have already been written (for example, from the first stroke F1 to the fourth stroke F4 in FIG. 5C). Information on the number of strokes is also included. If the determination program 2 is activated and the input of the handwritten data 18 of the first stroke F1 has not been received yet, nothing is stored in the current information 34.

  Thereafter, it is detected whether the pressure or the capacitance is changed by a writing operation using a finger or the like performed on the touch panel screen 4 (step S4). Here, when a writing operation is detected (YES in step S4), that is, when a movement of moving a finger or the like along the touch panel screen 4 is detected by the learning subject, the writing operation is first performed on the touch panel screen 4. At the coordinate position of the detected writing start coordinate P1, the plurality of writing coordinates P2 related to the coordinate position of the finger or the like during the writing operation per unit time defined in advance, and the writing end coordinate P3 where the finger or the like is separated from the touch panel screen 4 Such information is acquired, and input is accepted as writing data 18 (step S5). At this time, a stroke (such as the first stroke F1 in FIG. 5B) is displayed on the touch panel screen 4 in accordance with the movement of the finger or the like (step S6).

  Here, the current number of strokes is checked based on the accepted writing data 18 (step S7). The current stroke count is calculated as the number of strokes included in the current information 34 acquired in step S3 plus “1” based on the handwritten data 18 accepted this time. Then, the calculated number of strokes is compared with the total number of strokes defined in the stroke number data 11 of the kanji information 16 (5 in the case of “half”). At this time, if the condition “number of strokes ≦ total number of strokes” is satisfied (YES in step S7), the process proceeds to step S8 for determining whether or not the number of strokes is the first stroke. On the other hand, when the condition of “number of strokes ≦ total number of strokes” is not satisfied, that is, when the number of strokes (6 or more) larger than the original total number of strokes (here, “5”) is counted, extra strokes are written It is determined that the written kanji 5 is clearly not written correctly. For this reason, since it does not make a determination to perform the determination process in subsequent steps S8 to S14, the process proceeds to step S16b (details will be described later).

If the number of strokes is other than the first stroke (YES in step S8), a determination process based on the position data 14 that describes the relative positional relationship between the already-written writing and the new stroke that has received the writing data 18 is performed. Perform (step S9). For example, as shown in FIG. 5C, the third stroke F3 in “half”
(1) The writing start coordinate P1 of the third stroke F3 is located to the left and below the writing end coordinate P3 of the first stroke F1.
(2) The writing end coordinate P3 of the third stroke F3 is located to the right and below the writing end coordinate P3 of the second stroke F2.
(3) The line connecting the writing start coordinate P1 and the writing end coordinate P3 of the third stroke F3 is not positioned above the writing end coordinate P3 of the first stroke F1 and the second stroke F2.
The writing position conditions such as are defined in the position data 14,
The fourth stroke F4 is
(1 ′) The writing start coordinate P1 of the fourth stroke is located to the left and below the writing start coordinate P1 of the third stroke F3.
(2 ′) The writing end coordinate P3 of the fourth stroke is located to the right and below the writing end coordinate P3 of the third stroke F3.
The position data 14 defines a writing position condition such as. Then, it is determined whether or not the conditions (1) to (3) or (1 ′) to (2 ′) are satisfied according to the coordinate position of the accepted writing data 18. If these relative positional relationship conditions are not satisfied (YES in step S9), the result of position determination NG is stored in determination result data 33 (step S9a). On the other hand, if the condition is satisfied (NO in step S9), the process in step S9a is cancelled. In the determination process based on the position data 14 in step S9, a stroke order determination process based on the writing data 18 is also performed at the same time. Specifically, based on the current information 34 acquired in step S3, it recognizes up to which stroke has already been written at the current stage, and the new writing operation detected on the touch panel screen 4 is applied to the stroke in the next stroke order. It accepts as such writing data 18. Thereby, determination processing is performed based on the position data 14 corresponding to the stroke.

  Then, the presence / absence of the intersection C between the written stroke and the stroke currently being determined is detected, and it is determined whether or not the number and type of the intersection C match those specified in the position data 14. (Step S10). For example, as described above, in the case of “half”, the vertical image of the fifth stroke intersects the horizontal stroke of the third stroke and the four screens, respectively, and has two intersections C. Furthermore, the intersection C is divided into the case where the vertical image penetrates up and down as in the fifth half of the “half”, and the second vertical image relative to the third horizontal image as in the “soil”. Crosses so that they do not penetrate downward, or the vertical picture on the second screen does not penetrate upwards with respect to the horizontal picture of the first picture, and There are many types of intersection C such that the point of the third stroke does not penetrate to the left of the vertical image. Therefore, in step S10, the type of the intersection C is also determined. If the number and type of the intersection C are not correct (YES in step S10), the result of the intersection NG is stored in the determination result data 33 (step S10a). On the other hand, if the number and type of intersection C are correct (YES in step S10), the process of step S10a is canceled and the process proceeds to a process of determining the character shape of the stroke (step S11).

  Next, it is determined whether the accepted stroke shape of the written data 18 matches the reference character shape defined in advance by the stroke shape data 13 (step S11). For example, the first stroke of “half” is “a point that goes diagonally from the start point to the lower right”, and the third stroke is “a horizontal drawing that goes horizontally from the start point to the right”. Alternatively, the direction toward the end point is defined as the reference stroke shape, and it is determined whether the written stroke matches this. Note that the directions defined in the reference stroke shape are, for example, “up”, “down”, “right”, “left”, “oblique upper right”, “oblique lower right”, “oblique upper left”, and “oblique lower left”. "8" may be roughly defined. If the stroke shape does not match the reference character shape (YES in step S11), the result of the character shape NG is stored in the determination result data 33 (step S11a). On the other hand, when the stroke shape matches the reference character shape (NO in step S11), the process of step S11a is canceled, and the process proceeds to a calculation process of the movement distance L for performing determination by stroke of the stroke.

  After that, the movement distance L on the touch panel screen 4 between the writing end coordinate P3 of the writing data 18 and the writing coordinate P2 'immediately before it is calculated (step S12). Further, the stroke moving direction D is calculated at the same time (step S13). Then, based on the calculated movement distance L and movement direction D, the stroke of the stroke is compared with the stroke data 15 (step S14). Here, in the case of a stroke including “Splash” and “Harai”, the movement of the finger or the like on the touch panel screen 4 is inevitably faster, and the interval between the coordinate positions detected per unit time (movement distance L). Becomes longer. On the other hand, the movement distance L of “Tome” etc. is shortened. Therefore, the movement distance L is calculated from the writing end coordinate P3 and the writing coordinate P2 ′ immediately before the writing end coordinate P3, and when the movement distance L is long (for example, compared to the movement distance L not including “Harai” or “Splash”). In the case where the stroke is twice or more), it is determined that the stroke has a splash or splash. If the determination does not match the stroke data 15 (YES in step S14), the result of stroke NG is stored in the determination result data 33 (step S14a). On the other hand, if it matches the stroke data 15 (NO in step S14), the process of step S14a is canceled and the process proceeds to step S15.

  If there is no NG determination result in the determination process of steps S8 to S14 (excluding steps S12 and S13) (YES in step S15), it is determined that the writing kanji 5 is being written correctly, The final determination result data 33 of the handwriting determination OK is acquired (step S16a). On the other hand, if at least one NG determination result is stored in the determination result data 33 in each determination process (NO in step S15), it is determined that the written kanji 5 is not correctly written, and the final stroke determination NG is determined. Determination result data 33 is acquired (step S16b). Thereafter, the current information 34 is updated based on the accepted writing data 18 and the determination result data 33 relating to the determination result (step S17). And the presence or absence of operation which taps the determination button (not shown) displayed on the touch panel screen 4 for displaying a determination result is detected (step S18). Here, when the tap operation of the determination button is detected (YES in step S18), the number of strokes based on the updated current information 34 is compared with the total number of strokes defined in the stroke number data 11, and “number of strokes = total number of strokes” is obtained. Is determined (step S19). On the other hand, when the tap operation of the determination button is not detected (NO in step S18), the process proceeds to step S4 and waits until the writing operation for the next stroke is detected.

  When the number of strokes matches the total number of strokes in step S19 (YES in step S19), the determination result in step S16a or step S16b is displayed as it is (step S20). On the other hand, if the number of strokes does not match the total number of strokes (NO in step S19), that is, if the number of strokes written to the total number of strokes is insufficient, it is apparent that writing kanji 5 has been written incorrectly. Even if it is determined and the handwriting determination is determined to be OK in step S15, it is changed to the determination result of the handwriting determination NG (step S21), and then the determination result is displayed (step S20). Thereby, the determination of the writing accuracy for the writing kanji 5 is completed. Thereafter, when the determination system 1 is further continued to determine other writing kanji 5 as well, the presence / absence of input of the instruction is detected (YES in step S22), the process proceeds to step S2, and a new writing kanji 5 is detected. The kanji information 16 is extracted. On the other hand, when there is no input regarding the system continuation (NO in step S22), the system is terminated (step S23).

  As described above, the determination system 1 of the present embodiment performs determination for each stroke of the written kanji 5 written on the touch panel screen 4 of the tablet terminal 3 and displays the final determination result of the writing accuracy. Can do. Here, the determination result can present what screen and where was wrong, and the learner can confirm the point to pay attention to the next opportunity. As a result, it is possible to quickly learn to write the written kanji 5 correctly.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  For example, in the determination system 1 of the present embodiment, the one that obtains the determination result of the stroke determination OK when all the determination criteria such as the number of strokes, the stroke order, and the relative positional relationship are cleared is shown. The part may be relaxed. In other words, when targeting elementary school children in the lower grades, for example, if the determination of the relative positional relationship, the intersection, and the type of intersection is set too strictly, the determination result of the stroke determination NG may be frequently displayed. . Therefore, the above criteria may be relaxed for lower grades. Furthermore, although what showed the determination of the writing data 18 in the order shown from step S8 to step S14 was shown, it is not limited to this, You may perform a determination process in arbitrary orders. Furthermore, although the display of the determination result is shown after writing all the strokes constituting the written kanji 5 and pressing the determination button, the present invention is not limited to this. For example, the determination result is displayed for each stroke. In the case where the stroke determination NG is expressed, the next stroke may not be written.

  Furthermore, in the determination system 1 of the present embodiment, the terminal storage device 32 that stores various information such as the kanji information 16 is provided in the tablet terminal 3, but is not limited to this, for example, a tablet The terminal 3 may be provided with a communication function such as the Internet to read out the kanji information 16 stored in the external server as needed and write the determination result data 33 to the external server each time. Thereby, kanji to be taken in all grades of the elementary school can be learned without being limited by the processing capability and storage capacity of the tablet terminal 3. Furthermore, the determination items in the stroke shape data 13, the position data 14, and the stroke data 15 can be increased, and more accurate determination processing can be performed.
