JP 2002-282541 A

  In the conventional image recognition used in the game device shown in Patent Document 1, in order to identify and identify the type of handwritten graphic, the similarity between the handwritten graphic and a pre-stored model graphic is determined. It is necessary to determine. Here, in order to determine the degree of similarity, it is common to use a technique such as calculating the magnitude of correlation between handwritten graphic data and model graphic data. However, this requires an enormous amount of calculation, and the processing is relatively heavy. In order to make a quick determination, a high processing capacity is required.

  The present invention has been made in view of such a problem, and an object of the present invention is to easily perform processing relating to image recognition.

The first invention for solving the above problems is:
Computer
The degree of similarity between a handwritten figure (for example, the handwritten figure 444 in FIG. 6) input to the touch panel by a user's handwriting operation and a predetermined example figure (for example, the example figure 440a in FIG. 6) is expressed as the handwriting. Similarity determination means for determining based on the difference between the relative position of each dot constituting the figure in the handwritten figure and the relative position of each dot constituting the figure in the example figure (for example, FIG. 6 is a program for functioning as the similarity score calculation unit 524) of FIG.

In addition, the twelfth invention

  According to the first aspect or the twelfth aspect, the degree of similarity of the graphic is determined from the relative relationship between the dot position of the handwritten graphic and the dot position of the model graphic. In other words, there is no need to perform complicated calculations such as disassembling a handwritten figure into line segments, calculating the length and angle of each line segment, and comparing with the example figure. Therefore, since the similarity can be determined, the similarity can be determined by a relatively simple process. The handwritten figure is input to the touch panel. For this reason, since a handwritten figure can be recognized as an aggregate of touch-operated dots, it can be used as it is for determination of similarity as it is, and can be said to be a rational determination method.

The second invention is the program of the first invention,
Causing the computer to function as a model graphic display control means (for example, the game calculation unit 520 in FIG. 6; steps A12 and A16 in FIG. 9) for controlling the display of the model graphic;
The degree-of-similarity determination means causes the computer to function to determine the degree of similarity between a handwritten graphic input to the touch panel with respect to the display-controlled model graphic and the model graphic;
It is a program for.

  According to the second aspect, since the model figure is displayed and controlled, the user can input the handwritten figure by imitating the model figure whose display is controlled.

The third invention is the program of the second invention,

The example figure display control means causes the computer to function to display and control the example figure on the display device of the touch screen;
The similarity determination means causes the computer to function to determine the similarity between a handwritten graphic input by handwriting operation on the display-controlled model graphic and the model graphic;
It is a program for.

  According to the third aspect, since the model figure is displayed on the touch screen, the user can input the handwritten figure by tracing the model figure.

A fourth invention is a program according to any one of the first to third inventions,

  According to the fourth aspect of the invention, when there is a dot at a position away from the dot position of the model figure within the range satisfying the short distance condition, the number of the dots is considered when determining the similarity. It will be. Therefore, when a dot that satisfies the short distance condition works in a direction that is advantageous for determining the similarity, an advantageous determination result can be obtained even if the handwriting operation input is slightly shifted within the range that satisfies the short distance condition. . On the other hand, if a dot that satisfies the short-distance condition works in a direction that is disadvantageous in determining the similarity, a more accurate handwriting input that does not allow subtle deviations due to handwriting input may be requested.

The fifth invention is the program of the fourth invention,

Is possible. In addition, by tightening the short distance condition (narrowing the range), it is possible to easily determine that the handwritten figure is not similar when the dot position of the handwritten figure is away from the dot position of the model figure. . Thus, by changing the short distance condition, it is possible to change the difficulty level of handwriting input.

A sixth invention is a program according to any one of the first to fifth inventions,

A program for causing the computer to function so as to have step C18).

  According to the sixth aspect of the invention, the degree of similarity is adjusted according to the difference between the number of dots constituting the inputted handwritten figure and the number of dots constituting the example figure. Therefore, even when the user inputs a handwritten figure with a large number of dots without any darkness, more accurate determination can be performed by adjusting the degree of similarity to be low.

The similarity determination unit is a program for causing the computer to function so as to determine the similarity using the graphic scaled by the scaling unit.

  According to the eighth aspect, since the handwritten figure is enlarged or reduced to the size of the example figure, or the example figure is enlarged or reduced to the size of the handwritten figure, the user does not care about the size of the figure. What is necessary is just to input the handwritten figure of the same shape as this figure.

The example figure is composed of a plurality of part figures (for example, part figure group 470a in FIG. 24),
Based on the arrangement configuration information defined for the arrangement configuration of the component figures constituting the example figure, the example figure creating means (for example, FIG. 6, the computer is caused to function as a game calculation unit 520; step E 14 in FIG.
The similarity determination means causes the computer to function to determine the similarity between the model graphic created by the model graphic creation means and the handwritten graphic;
It is a program for.

  According to the ninth aspect, a model figure can be created by combining part figures. Therefore, for example, when determining the degree of similarity between each massive figure and a handwritten figure, it is not necessary to secure a storage capacity for storing the entire image data of each figure, and the figure figure is configured. The capacity for storing the part graphic data to be stored and the arrangement configuration information of the part graphic is sufficient.

  Hereinafter, embodiments of the present invention applied to a portable game device will be described in detail with reference to the drawings.

〔appearance〕
FIG. 1 is a schematic external view of a portable game apparatus 1 to which the present invention is applied. According to the figure, the operation key 3, the display 5 including the main display 5a and the sub display 5b, and the speaker 7 are provided, and a game cassette GC which is an external storage medium of the game apparatus 1 is provided on the side of the casing.

  The display 5 is composed of a color liquid crystal display such as a TFT (Thin Film Transistor). Further, as shown in FIG. 2, the touch panel 4 is integrally formed on the upper surface (or lower surface) of the sub display 5b, and the sub display 5b and the touch panel 4 constitute a touch screen. The touch panel 4 indicates the touched position (position where the touch pen 9 is in contact) on the sub display 5b by a detection method such as a pressure sensitive type, an optical type, an electrostatic type, or an electromagnetic induction type, for example, a dot constituting the sub display 5b. It detects in units, and outputs a signal (touch operation signal) of the detected position (hereinafter referred to as “touch position” as appropriate) P. The touch position P is expressed in the XY coordinate system set as the coordinate system of the detection surface of the touch panel 4. The user can perform various operation inputs by touch operations on the sub-display 5b using the attached touch pen PN or a finger.

  Note that information (system program, game program, game data, etc.) necessary for the game apparatus 1 to execute the game is external information that is detachable from the IC memory mounted on the control unit in the housing or the game apparatus 1. It is stored in a game cassette GC which is a storage medium.

[First Embodiment]
First, the first embodiment will be described. The first embodiment is an embodiment relating to a game in which a figure as a model is displayed on the display 5b, and the figure is handwritten and input by performing a touch operation so as to trace the figure.

[1.1 Principle of similarity score calculation method]
First, the principle of the method for calculating the number of similar points will be described. Here, the similarity score refers to a figure handwritten by the user (hereinafter referred to as “handwritten figure” as appropriate) and a figure stored as a model in the game apparatus 1 (hereinafter referred to as “example figure” as appropriate). .) Represents the degree of similarity, and the higher the number of similar points, the more similar the handwritten figure and the example figure are. In addition, the figure in this specification is not restricted to pictures, such as a line drawing and a picture, A character, a number, a symbol, etc. may be sufficient.

  FIG. 3A is a diagram for explaining a display screen GS10 on which a model figure representing the character “person” is displayed. For simplicity of explanation, the number of dots on the display screen is simplified and described as a display screen having 5 dots in the horizontal direction (X direction) and 5 dots in the vertical direction (Y direction). Further, the X direction (column direction) is represented by alphabets, the Y direction (row direction) is represented by numbers, and the position of each dot is represented by a combination of alphabets and numbers. For example, the dot in the first row of the C column is represented as a dot C1. On the display screen GS10, the dots C1, C2, C3, B4, A5, D4 and E5 are lit. Hereinafter, the lit dot is referred to as a display dot.

  Evaluation points corresponding to the display dots of the model figure will be described. FIG. 3B is a diagram for explaining the evaluation points of the example figure “people”. Evaluation points are set corresponding to the dots on the display screen. Hereinafter, a set of evaluation points set corresponding to each dot on the display screen is referred to as an “evaluation table”, and a position where each evaluation point is arranged is referred to as a “cell”. That is, in FIG. 3B, the X direction (column direction) and Y direction (row direction) of the display screen GS10 correspond to the X direction and Y direction of the evaluation table GS20, and each dot of the display screen GS10. Corresponds to each cell of the table GS20. For example, the dot A1 corresponds to the cell A1. Furthermore, an evaluation score of “0” is stored in each cell of the table GS20.

  In the cell corresponding to the display dot of the display screen GS10, “2” is set as the evaluation point. Specifically, “2” is set in each of the cells C1, C2, C3, B4, A5, D4, and E5 corresponding to the display dots of the display screen GS10.

  In addition, “1” is set to the display dot of the display screen GS10 and the cell that satisfies the predetermined short-distance condition. In the present embodiment, a cell that is “one” away from a cell corresponding to a display dot on the display screen GS10 (a cell for which “2” is set as an evaluation point) is set as a short distance condition. Therefore, in cells around the cell for which “2” is set as the evaluation point, a cell other than the evaluation point “2” becomes a cell that satisfies the short-distance condition, and the evaluation point “1” is set in the cell. Has been. For example, the cells around the cell C3 are eight cells B2, C2, D2, B3, D3, B4, C4, and D4. The short distance condition may be a cell that is “within two” away. Based on this short distance condition, similarity determination can be performed in consideration of some deviation or blurring due to handwriting operation.

  Next, FIG. 3C is a diagram for explaining the display screen GS30 on which a handwritten graphic is displayed. The X direction (column direction) and Y direction (row direction) of the display screen GS30 correspond to the X direction and Y direction of the table GS20, and each dot of the display screen GS30 corresponds to each cell of the table GS20. Yes.

  The user performs a touch operation, and the dot at the touched position is lit and displayed, and a handwritten figure is configured. On the display screen GS30, dots D1, D2, C3, B4, A5, D4, and E4 are lit. Hereinafter, the dots that are lit in correspondence with the touch positions are referred to as drawing dots.

  The number of similar points is calculated by reading the evaluation points corresponding to each drawing dot from the table GS20 and summing them up. For example, the evaluation point corresponding to the dot D1 that is lit and displayed on the display screen GS30 is the cell D1 “1”. Similarly, the evaluation points corresponding to the drawing dots are read from each cell of the table GS20 and totaled. In the case of the handwritten graphic of FIG. 3C, the total of the evaluation points is “11”, and the number of similar points is “11”.

  Next, the total value of the evaluation points is adjusted. For example, in the case of a handwritten figure as shown in the display screen GS40 of FIG. 4, when the evaluation points corresponding to the drawing dots are simply read from the cells and totaled, the total of the evaluation points is calculated as “19” points. Therefore, this is corrected.

  There are several adjustment methods. For example, when the number of drawing dots of a handwritten figure exceeds the number of display dots based on the example figure, the number of points exceeding the number of display dots is a method of subtracting from the total of the evaluation points. For example, every time the number of drawing dots exceeds the number of display dots, “2” points are deducted.

  Of course, other adjustment methods may be used. For example, when the number of drawing dots exceeds a predetermined ratio of the number of display dots of the model figure, points may be deducted according to the exceeding ratio. For example, if it is within the range of “± 30%” of the number of displayed dots, the number obtained by multiplying the number of excess dots by “1.5” is deducted, and if it exceeds “± 30%”, the number is exceeded. A point obtained by multiplying the number of dots by “2.0” is subtracted.

  Actually, the area where the model graphic is displayed and the area where the handwritten graphic is input are not in a fixed range and position where the number of vertical and horizontal dots is determined as shown in FIG. The handwritten figure is cut out based on the position and range of the handwritten figure input by the touch operation on the touch panel 4, and may be appropriately enlarged or reduced to a size comparable to the model figure. Therefore, in the explanation of the present principle, the position of each dot constituting the example figure and the position of each dot constituting the handwritten figure are simply compared, but if this is accurately expressed, This means that the relative position of each dot constituting the main figure in the model figure is compared with the relative position of each dot constituting the handwritten figure in the handwritten figure.

[1.2 Screen example]
FIG. 5 is a diagram showing an example of a game screen displayed on the sub-display 5b in the present embodiment. The game screen GW10 shown in FIG. 5A is provided with a handwriting input area NA10, and a model figure NZ10 is displayed lightly in the handwriting input area NA10. Also, a comment CA10 “Trace the line” that gives an instruction to the user is displayed, and an end button BA10 for detecting the end of handwriting input is displayed.

  When the user performs a touch operation on the sub-display 5b (touch panel 4) using the touch pen PN, a position where the touch pen PN contacts is detected as a touch position. When the detected position is in the handwriting input area NA10, a drawing dot is displayed at the touch position. Furthermore, by performing a touch operation (sliding touch operation) with the touch pen PN so as to overwrite the displayed example figure NZ10, the trajectory passed by the touch pen PN is displayed by continuous drawing dots. Further, when the end button BA10 is touch-operated, the handwriting input is ended.

  FIG. 5B is a diagram illustrating an example of the game screen GW12 that shows a state in which a handwritten graphic is input by the user. In the handwriting input area NA10 of the game screen GW12, the input handwritten figure KZ10 is displayed so as to be superimposed on the example figure NZ10. When the end button BA10 is touched with the touch pen PN, the number of similarities of the handwritten figure KZ10 is calculated.

  The game screen GW14 of FIG. 5C represents the game screen after the similarity score is calculated. On the game screen GW14, a handwritten graphic KZ14 is displayed, and the number of similarities of the handwritten graphic and the comment CA12 “It's a little more!” Corresponding to the number of similarities are displayed as evaluation results.

  The operation input unit 100 receives an operation instruction from a user and outputs an operation signal corresponding to the operation to the processing unit 500. This function is realized by, for example, a button switch, lever, dial, mouse, keyboard or the like. In FIG. 1, the operation key 3 corresponds to this. The operation input unit 100 includes a touch panel 150 and outputs a touch operation signal detected by the touch panel 150 to the processing unit 500.

  Based on the image signal from the image generation unit 540, the main display unit 200 and the sub display unit 220 display the screen while redrawing the screen of one frame every 1/60 seconds, for example. This function is realized by hardware such as CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), ELD (ElectroLuminescent Display), and PDP (Plasma Display Panel). In FIG. 1, the main display 5 a corresponds to the main display unit 200, and the sub display 5 b corresponds to the sub display unit 220.

  The sound output unit 300 outputs game sound such as BGM and sound effects based on the sound signal from the sound generation unit 560. This function is realized by, for example, a speaker. In FIG. 1, the speaker 7 corresponds to this.

  The storage unit 400 stores a system program for realizing various functions for the processing unit 500 to control the game apparatus 1 in an integrated manner, a program and data necessary for executing the game, and the processing unit 500 is used as a work area, and temporarily stores calculation results executed by the processing unit 500 according to various programs, input data input from the operation input unit 100, and the like. This function is realized by, for example, various IC memories (RAM), hard disks, CD-ROMs, DVD-ROMs, MO (Magneto-Optical disks), and the like. In FIG. 1, an IC memory mounted on a control unit built in the game apparatus 1 and an external information storage medium such as a game cassette GC correspond to this.

  In addition, the storage unit 400 stores a first game program 420 for causing the processing unit 500 to function as the game calculation unit 520, problem data 440, a display size graphic 442, a handwritten graphic 444, and an evaluation table 446. The The first game program 420 further includes an evaluation table generation program 422 and a similarity score calculation program 424. The evaluation table generation program 422 is a program for creating the evaluation table 446 from the display size graphic 442, and causes the game calculation unit 520 to function as the evaluation table generation unit 522. The similarity score calculation program 424 is a program for calculating the similarity score of the handwritten figure 444 based on the evaluation table 446, and causes the game calculation unit 520 to function as the similarity score calculation unit 524.

  The question data 440 is data in which a plurality of example figures 440a are stored, and has a structure in which the example figure to be presented next can be appropriately selected according to the game progress status. FIG. 7 shows an example of a link structure between the model figures. As shown in FIG. 7, the first example graphic includes the second example graphic and the third example graphic, and the second example graphic includes the fourth example graphic and the fifth example graphic. A link like a branch structure is stretched between each model figure. The first example figure of the game is the first example figure. If the evaluation result of the handwritten graphic input by the user is good (if the number of similar points is high), the second sample graphic that is a graphic (difficult graphic) having a high difficulty level is selected. On the contrary, if the evaluation result of the handwritten figure is bad (if the number of similar points is low), the third example figure that is a figure (easy figure) with a low difficulty level is selected. Thereafter, similarly, the model figure to be presented next is changed according to the game progress status.

  In FIG. 7, for ease of explanation, two stages of “difficult” and “easy” are illustrated and described as branch destinations. However, depending on the content of evaluation, multiple stages such as three stages and four stages are shown. Of course, it is also possible to make it.

  The display size figure 442 is a figure in which the model figure 440a is enlarged / reduced to a size suitable for the size of the area for displaying the model figure, and the number of dots is set in accordance with the dot density of the display area. The game calculation unit 520 uses the display size graphic 442 to determine whether or not the handwritten graphic 444 and the model graphic 440a are similar. The handwritten figure 444 is a figure input by handwriting by the user.

  The evaluation table 446 is an evaluation table generated from the display size graphic 442 by the evaluation table generating unit 522, and an evaluation score is set for each cell as shown in FIG. An evaluation point “2” is set in a cell corresponding to a dot constituting the display size figure 442 (hereinafter referred to as “display size figure dot” as appropriate), and a cell (1 cell) around the display size figure dot is set. The evaluation score “1” is set for (minute). It should be noted that various interests such as changing the difficulty level of the game can be given by changing the evaluation points of the evaluation table 446. For example, the evaluation point “4” is set to the cell corresponding to the display size figure dot, and the evaluation point of the other cell is set to “−1”, so that the model figure can be traced more accurately. Or can be a game.

  The processing unit 500 performs various arithmetic processes such as overall control of the game apparatus 1, game progress, and image generation. This function is realized by, for example, an arithmetic device such as a CPU (CISC type, RISC type), ASIC (gate array, etc.) or a control program thereof.

  The processing unit 500 includes a game calculation unit 520 that mainly performs calculation processing related to the execution of the game, an image generation unit 540 that generates a game image based on a processing result of the game calculation unit 520, sound effects, BGM, and the like.

Specifically, a display size graphic 442 is created based on the model graphic 440 a read from the problem data 440 and displayed on the sub display unit 220 in a predetermined light color. Further, by using the evaluation table 446, the handwritten graphic input by the user is compared with the model graphic, the number of similar points is calculated, and evaluation according to the calculation result is performed.

  The image generation unit 540 generates a game screen based on the processing result of the game calculation unit 520, and outputs the generated game screen image signal to the main display unit 200 and the sub display unit 220. The sound generation unit 560 generates a game sound such as a sound effect or BGM during the execution of the game based on the processing result of the game calculation unit 520, and outputs a sound signal of the generated game sound to the sound output unit 300.

  In addition, the game calculation unit 520 described above includes an evaluation table generation unit 522 and a similarity score calculation unit 524.

  The evaluation table generation unit 522 performs processing for generating the evaluation table 446 based on the display size graphic 442. Specifically, the evaluation table generation unit 522 generates the evaluation table 446 by setting the evaluation score “2” in the cell corresponding to the display size graphic dot and setting the evaluation score “1” in the cell adjacent to the cell. To do.

  The similarity score calculation unit 524 performs processing for calculating the similarity score of the handwritten graphic 444 by using the evaluation table 446. Specifically, the similarity score calculation unit 524 reads out the evaluation points corresponding to the dots constituting the handwritten graphic 444 (hereinafter, referred to as “handwritten graphic dots” as appropriate) from the evaluation table 446 and totals the evaluation points. calculate. Here, when the number of handwritten figure dots exceeds the number of display size figure dots, a process of adjusting the calculated number of similar points is performed based on the excess dot difference.

[1.4 Process flow]
Next, the processing flow will be described with reference to FIGS. Each process is realized by the game operation unit 520 reading and executing the first game program 420.

  FIG. 9 is a flowchart for explaining the flow of the first game process. The game calculation unit 520 selects the model figure 440a stored in the problem data 440 (step A10). Here, since it is the first selection, the first example figure is selected.

  Subsequently, the game calculation unit 520 creates a display size figure 442 from the selected example figure 440a (step A12). Then, the evaluation table generation unit 522 executes an evaluation table creation process (step A14). FIG. 10 is a flowchart for explaining the flow of the evaluation table generation process.

  As shown in FIG. 10, the evaluation table generating unit 522 sets the evaluation score “2” in the cell of the evaluation table 446 corresponding to the display size graphic dot (step B10). Subsequently, “1” is set to cells other than the evaluation score “2” among the cells around the cell where the evaluation score “2” is set (step B12). Then, the evaluation table generation unit 522 ends this process.

  Returning to FIG. 9, when the evaluation table creation processing is completed, the display size graphic 442 is displayed in a predetermined light color on the sub display unit 220 (step A <b> 16), and a sentence such as “Trace the line!” Is displayed. This prompts the user to input a handwriting operation of the handwritten graphic 444 (step A18). When the end of handwriting input is detected (step A20; Yes), the similarity score calculation unit 524 executes a similarity score calculation process (step A22). FIG. 11 is a flowchart for explaining the flow of the similarity score calculation process.

  In FIG. 11, the similarity score calculation unit 524 calculates the difference between the number of handwritten graphic dots and the number of display size graphic dots as a dot difference (step C10). Next, the similarity score calculation unit 524 determines whether the dot difference is within ± 30% of the number of display size dots (step C12). Here, when the dot difference is not within ± 30% of the number of display size figure dots (step C12; No), the similarity score is set to “−1” (step C20), and the similarity score calculation process is terminated. .

  If the dot difference is within ± 30% of the number of display size dots (step C12; Yes), the evaluation points corresponding to the handwritten graphic dots are read from the evaluation table 446 and totaled to obtain the similarity score. (Step C14). Here, when the dot difference calculated in step C10 is larger than “0” (step C16; Yes), the similarity score calculation unit 524 calculates the score for “dot difference × 2” in step C14. The similarity score is updated by subtracting from the similarity score (step C18), and the similarity score calculation process is terminated.

  Returning to FIG. 9, when the similar score calculation process ends, the game calculation unit 520 performs an evaluation based on the similar score calculated in the similar score calculation process, and executes an effect corresponding to the evaluation result (step A <b> 24).

  For example, if the number of similar points is “90 points” or more, “Very well!” Is displayed on the sub display unit 220 as a comment. Also, if the number of similar points is greater than or equal to “60” and less than “90”, “A little more!” Is commented, and if the number of similar points is less than “60”, “Carefully follow ...” indicate. Moreover, it is good also as outputting a sound effect or displaying an animation with the comment mentioned above. Further, the calculated number of similar points may be displayed as a score.

  Here, when an operation for ending the first game process is not detected from the user (step A26; NO), the game calculation unit 520 selects the next example figure 440a. At this time, if the number of similar points is “60 points or more”, a model figure that is more difficult than the current example figure is selected. If the number of similar points is “less than 60 points”, an example figure that is easier than the current example figure is selected. Selection is made from the problem data 440 (step A28).

  For example, in the case of the problem data 440 shown in FIG. 7, it is assumed that the model figure currently presented is the first model figure. If the similarity score is “60 points or more”, the game calculation unit 520 selects the second example graphic (tehon2.bmp). If the number of similar points is “less than 60”, the game calculation unit 520 selects the third example figure (tehon3.bmp).

  In the first game process, the example figure 440a has been described as automatically selected by the game calculation unit 520, and for example, the figure arbitrarily selected by the user from the example figures displayed in a list. Of course, it is also good to ask questions.

[1.6 Action and effect]
As described above, according to the first embodiment, the number of similar points can be obtained by comparing the positions of the dots constituting the model figure and the positions of the dots constituting the handwritten figure. Therefore, it is not necessary to perform a complicated calculation related to image recognition, which is conventionally performed, such as by dividing the handwritten figure 444 into line segments and comparing the lengths and angles of the line segments, and the similarity can be determined by simple processing. . Further, since the model figure 440a is displayed on the sub display unit 220, the user can input the handwritten figure 444 by performing a sliding operation so as to trace the displayed model figure 440a.

[1.7 Modification]
In addition, although it demonstrated as selecting the example figure 440a chosen as a next question according to evaluation based on the number of similar points, it is good also as changing the evaluation score of the evaluation table 446 which the evaluation table production | generation part 552 sets further. Specifically, when the evaluation score is low, the evaluation table generation unit 522 expands the range of surrounding cells for setting the evaluation score “1” from one cell to two cells. In this case, even if the handwritten graphic 444 deviates from the model graphic 440a, more evaluation points can be obtained.

  If the number of similar scores is high, the evaluation score of the cell corresponding to the display size figure dot may be “4”, and the evaluation score of other cells may be all “1”. In this case, when the next question is given when the number of similar scores is high, it is possible to request to request a more accurate handwritten figure. In this way, various game progresses can be realized by changing the position of the evaluation point and the value of the evaluation point set in the evaluation table 446 in accordance with the evaluation (number of similar points) of the handwritten graphic 444.

[Second Embodiment]
Next, a second embodiment will be described. The second embodiment is an embodiment for identifying which candidate figure is most similar to a handwritten figure input by handwriting among a plurality of example figures (hereinafter referred to as “candidate figure” as appropriate). In the second embodiment, the same elements as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

[2.1 Screen example]
FIG. 13 is a diagram showing an example of a game screen displayed on the sub-display 5b. On the game screen GW20 shown in FIG. 13, a problem image MZ20 is displayed, and a handwriting input area NA20 is also set. Also, a problem comment CA20 “Let's draw a hat!” Prompting the user to input a handwriting operation is displayed. In addition, an end button BA20 for detecting the end of handwriting input is displayed.

  When the user inputs a handwritten figure by sliding the input area NA20, the handwritten figure KZ20 is displayed on the game screen GW20 with drawing dots.

  FIG. 14 is a schematic diagram in which the handwritten figure KZ20 is enlarged and displayed in dot units. Here, the shaded portion is a drawing dot in the handwritten graphic KZ20. The game apparatus 1 calculates the similarity score for each candidate graphic to determine which candidate graphic is most similar among the plurality of candidate graphics stored in the game apparatus 1 for the input handwritten graphic KZ20. By recognizing, the figure of the handwritten figure KZ20 is recognized.

  An example of a candidate graphic and an evaluation table for the candidate graphic is shown in FIG. For example, FIG. 15A shows a candidate graphic SZ20 and an evaluation table HT20 corresponding to the candidate graphic SZ20. Similarly, FIG. 15 (b) shows the candidate graphic SZ22 and the corresponding evaluation table HT22, and FIG. 15 (c) shows the candidate graphic SZ24 and the corresponding evaluation table HT24.

  When the number of similarities of the handwritten graphic KZ20 with respect to each candidate graphic SZ20, SZ22, SZ24 is calculated with reference to each evaluation table of FIG. 15, “34” points for the candidate graphic SZ20 and “70” for the candidate graphic SZ22. In the case of the point and the candidate graphic SZ24, “44” points are calculated. Therefore, it recognizes that candidate graphic SZ22 with the largest number of similarities was inputted by handwriting.

  FIG. 16 is a diagram illustrating an example of a game screen displayed on the game apparatus 1 when a handwritten graphic is recognized and evaluated. In the game apparatus 1, a game screen GW22 is displayed on the main display 5a, and a game screen GW24 is displayed on the sub display 5b. A problem image MZ22 is displayed on the game screen GW24, and a handwritten graphic KZ22 is displayed in the handwriting input area NA22. In addition, the problem image MZ22 is displayed in the same manner on the game screen GW22, and a candidate graphic NZ22 similar to the handwritten graphic KZ22 is displayed. The user can confirm the recognition result of the handwritten graphic KZ22 by visually recognizing the candidate image NZ22.

  Furthermore, on the game screen GW 24, a comment corresponding to the determined candidate graphic (hereinafter referred to as “candidate graphic comment” as appropriate) and a comment corresponding to the range of the similar score (hereinafter referred to as “similar score comment” as appropriate). Is displayed as a comment CA22. For example, when it is recognized as the candidate graphic SZ20 in FIG. 15A, it is “a great hat!”, And when it is recognized as the candidate graphic SZ22 in FIG. 15B, it is “a cool hat! "Is recognized as a candidate graphic SZ24 in FIG. 15C," isn't it a strange hat? "Is displayed. Also, a similar score comment is displayed according to the determined similar score of the candidate graphic. For example, if the number of similar points is “80” or more, “You are very good! You know what kind of hat you have right away!”, But if the number of similar points is “60” or more and less than “80”, If you're a little worried, but this hat is "40" points or more and less than "60" points, "If you've made this hat from the atmosphere of the picture!" If it is less than "40" points Is displayed as “It was a hat I couldn't imagine. The handwritten graphic KZ22 is recognized as the candidate graphic SZ22, and “70” points are calculated as the number of similar points. Is displayed.

[2.2 Functional configuration]
The functional configuration of the game apparatus 1 in the second embodiment is the same as the configuration in which the storage unit 400 is replaced with the storage unit 400b shown in FIG. 17 in the functional configuration of the game apparatus 1 shown and described in FIG. 6 in the first embodiment. Hereinafter, the same components are denoted by the same reference numerals, and the description thereof is omitted.

  As illustrated in FIG. 17, the storage unit 400b includes the second game program 420b, the problem data 450, the display size graphic 442, the handwritten graphic 444, the evaluation table 446, the similarity score data 452, and the similarity score comment 454. And are stored. The second game program 420b includes an evaluation table generation program 422 and a similarity score calculation program 424.

  The second game program 420b is a program executed by the game calculation unit 520. When the game calculation unit 520 executes the second game program 420b, the handwritten figure 444 inputted by handwriting is compared with each candidate figure of the candidate figure group 450b to calculate the number of similar points. Then, the candidate graphic with the highest number of similar points is recognized as a handwritten input by the user, and an effect is produced according to the recognized candidate graphic and the number of similar points.

  As shown in FIG. 18, the problem data 450 includes a problem number (for example, “1”), a problem comment (for example, “Let's draw a hat!”), And a problem image 450a (for example, “syutu1.bmp”). And a candidate graphic group 450b having a plurality of candidate graphics. Furthermore, a candidate graphic comment displayed when the candidate graphic is selected is also stored. The candidate graphic group in this embodiment is described as including three candidate graphics from the first candidate graphic to the third candidate graphic, but the number of candidate graphics may be more than this. The number of candidate graphics may differ for each problem number.

  The similarity score data 452 is data of the similarity score for each candidate graphic calculated by the similarity score calculation unit 524. As illustrated in FIG. 19, the similarity score data 452 stores a similarity score (for example, “34”) in association with each candidate graphic (for example, “first candidate graphic”).

  The similar score comment 454 stores a similar score comment corresponding to the similar score. For example, as shown in FIG. 20, when the number of similarities of the determined candidate graphic is “80 or more”, “You are very good! You know what you have drawn right away!” Is stored as a similarity score comment. Has been.

[2.3 Process flow]
Next, the flow of the second game process will be described with reference to FIG. The process described here is a process realized by the game calculation unit 520 reading and executing the second game program 420b.

  The game calculation unit 520 selects one problem data from the problem data 450 (step D10). Subsequently, the problem image 450a is displayed on the sub display unit 220 (step D12). Subsequently, the user is prompted to input a handwriting operation of the handwritten graphic 444 (step D14). When the input end of the handwritten graphic is detected (step D16; Yes), the game calculation unit 520 selects a candidate graphic from the candidate graphic group 450b corresponding to the problem data (step D18). Then, a display size graphic 442 is created from the candidate graphic (step D20).

  Subsequently, the game calculation unit 520 enlarges / reduces the handwritten figure 444 to a size corresponding to the display size figure 442 (step D22). For example, the position and area (size) on the touch panel 4 to which the handwritten graphic 444 is input are detected. Then, the handwritten graphic 444 is enlarged or reduced so that the size substantially matches the handwritten graphic in the area where the display size graphic 442 is displayed. For example, enlargement / reduction is performed so that the number of vertical and horizontal dots inscribed in the handwritten figure is the same as the number of vertical and horizontal dots in the rectangle inscribed in the handwritten figure 4. At this time, it is preferable to make the aspect ratio constant, but the aspect ratio may be made variable to match the aspect ratio of the model figure.

  And the evaluation table production | generation part 522 produces | generates the evaluation table 446 based on the display size figure 442 by performing an evaluation table production | generation process (step D24). Next, the similarity score calculation unit 524 calculates the similarity score of the handwritten figure 444 according to the generated evaluation table by executing a similarity score calculation process (step D26).

  When the similarity score calculation process ends, the game calculation unit 520 stores the calculated similarity score in the similarity score data 452 (step D28). If the number of similarities of the candidate graphic group 450b of the currently selected problem data 450 has not been calculated (step D30; No), the process is repeated from step D18.

  When the number of similar points for all candidate figures included in the selected problem has been calculated (step D30; Yes), the candidate figure having the maximum number of similar points stored in the number of similar points data 452 is determined (step). D32). Then, the game calculation unit 520 reads a candidate graphic comment corresponding to the determined candidate graphic from the problem data 450 and reads a similar score comment corresponding to the similar score from the similar score comment 454. Then, the read similarity score comment and the candidate graphic comment are displayed together on the sub-display unit 220 (step D34). The determined candidate graphic is displayed at a predetermined position on the main display unit 200 (step D36).

  Here, when the end of the second game process is touched, the second game process is ended, and when the second game process is continued, the process is repeatedly executed from step D10.

[2.4 Action and effect]
Thus, according to the second embodiment, a candidate graphic that is most similar to a handwritten graphic can be selected. For this reason, in the present embodiment, the number of candidate figures is limited to three, so it may be difficult to convey. However, by performing a process similar to this embodiment with a large number of candidate figures, The figure assumed by the user at the time of input can be recognized. In addition, since the handwritten figure is cut out from the coordinate system of the touch panel 4 and scaled to a size suitable for comparison with the example figure, the user can perform a touch operation on the touch panel 4 and the size of the figure to be input by handwriting. You can enter handwritten figures freely without worrying about

[2.5 Modification]
In the present embodiment, it has been described that one candidate figure that is most similar to the figure input by handwriting is always determined, but it may be determined that there is no candidate figure that is similar according to the number of similar points. Specifically, in step D32 of FIG. 21, if the maximum value of the number of similar points stored in the similar point number data 452 is less than “40” points, a candidate graphic that can be said to be similar to the handwritten graphic cannot be recognized. The fact that the figure could not be recognized may be used as a candidate figure comment (for example, “I don't know what I wrote!”). In that case, a user re-inputs a handwritten figure by executing the process from step D14 again.

[Third Embodiment]
Next, a third embodiment will be described. The third embodiment is an embodiment in which a model graphic is displayed on the main display unit and a user inputs a handwritten graphic imitating the model graphic. In the third embodiment, the same elements as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

[3.1 Screen example]
FIG. 22 is a diagram illustrating an example of a game screen according to the present embodiment. In the game apparatus 1, a game screen GW30 is displayed on the upper main display 5a, and a game screen GW32 is displayed on the lower sub-display 5b. A model figure NZ30 is displayed on the game screen GW30. In addition, a comment CA 30 “Draw imitating this figure!” Prompting the user to input a handwriting operation is displayed.

  In the present embodiment, the model figure is composed of a plurality of part figures. For example, in FIG. 22, the example figure NZ30 is composed of a rhombus part figure BZ30, a straight part figure BZ32, a rectangular part figure BZ34, and three part figures. The model graphic is defined by the component arrangement conditions such as what the component graphic is constituting the model graphic, and in which position and size each component graphic is arranged.

  FIG. 23 is a diagram illustrating an example of a game screen when the user finishes inputting a handwritten graphic. A model figure NZ34 is displayed on the game screen GW34, and a handwritten figure KZ36 is displayed on the game screen GW36. Further, the number of similar points between the handwritten graphic 36 and the example graphic NA34 is calculated, and a comment corresponding to the number of similar points is displayed on the game screen GW34. For example, when the number of similar points is “80” or more, the comment CA34 “I was imitated!” Is displayed.

[3.2 Functional configuration]
The functional configuration of the game apparatus 1 in the third embodiment is the same as the configuration in which the storage unit 400 is replaced with the storage unit 400c shown in FIG. 24 in the functional configuration of the game apparatus 1 shown and described in FIG. 6 in the first embodiment. Hereinafter, the same components are denoted by the same reference numerals, and the description thereof is omitted.

  As illustrated in FIG. 24, the storage unit 400c stores a third game program 420c, problem data 470, a display size graphic 442, a handwritten graphic 444, and an evaluation table 446. The third game program 420c includes an evaluation table generation program 422 and a similarity score calculation program 424.

  The third game program 420c is executed by the game calculation unit 520 to read a part graphic from the part graphic group 470a and create a model graphic according to the model graphic component configuration data 470b. Then, when the model figure is displayed on the main display unit 200 and the handwritten figure 444 is input from the touch panel 150 configured integrally with the sub display unit 220, the number of similarities between the model figure and the handwritten figure 444 is calculated. Then, the production is performed according to the evaluation of the number of similar points.

  The problem data 470 is a data group of model figures, and has a structure in which a model figure to be presented next can be appropriately selected according to the game progress status. FIG. 25 shows an example of a link structure between the model figures. As shown in FIG. 25, the first example figure includes the second example figure and the third example figure, and the second example figure includes the fourth example figure and the fifth example figure. A link like a branch structure is stretched between each model figure. The first example figure of the game is the first example figure. If the evaluation result of the handwritten graphic input by the user is good (if the number of similar points is high), the second sample graphic that is a graphic (difficult graphic) having a high difficulty level is selected. On the contrary, if the evaluation result of the handwritten figure is bad (if the number of similar points is low), the third example figure that is a figure (easy figure) with a low difficulty level is selected. Similarly, the model figure to be presented next is changed according to the game progress status.

  Here, the model graphic is created based on the model graphic component configuration data 470b using the component graphic stored in the component graphic group 470a. FIG. 26 is a diagram illustrating an example of a component figure group 470a stored in the storage unit 400c. In the component graphic group 470a, the name of the component graphic and the graphic are stored in association with each other. In this figure, straight lines, squares, rectangles, rhombuses, and circles are stored.

  FIG. 27 is a diagram showing an example of the data configuration of the sample graphic part configuration data 470b, and stores the component graphic (for example, “diamond”) used in association with the model graphic number and the component graphic arrangement condition. is doing. The component graphic arrangement condition includes the position of the representative point of the part graphic in the entire model graphic (for example, “(40, 10)”), the scaling factor (for example, “1.0”) of the component graphic, An arrangement angle (for example, “0”) when the part figure is arranged as a model figure is stored. The game calculation unit 520 reads out the component graphic used for the model graphic from the component graphic group 470a, and arranges the component graphic in the game screen according to the component graphic arrangement condition. For example, if the enlargement / reduction ratio is “1.0”, it is arranged at the same size as the part graphic. Arrange. If the angle is “90”, the component figure is arranged by being rotated “90 degrees” clockwise (or counterclockwise).

[3.3 Process flow]
Next, the flow of the third game process will be described with reference to FIG. The process described here is a process realized by the game calculation unit 520 reading and executing the third game program 420c.

  The game calculation unit 520 selects a model figure stored in the problem data 470 (step E10). Here, the example figure selected first is, for example, the first example figure.

  Subsequently, the game calculation unit 520 creates a model figure (step E12). Specifically, a model figure is created by arranging part graphics in accordance with model figure component configuration data 470b.

  Subsequently, the game calculation unit 520 displays the created model figure on the display image, but creates a display size figure 442 as temporary data for display (step E14). And the evaluation table production | generation part 522 performs the evaluation table preparation process, and produces the evaluation table 446 (step E16).

  Next, the display size figure 442 is displayed on the main display unit 200 (step E18), and the user is prompted to input the handwriting operation of the handwritten figure 444 (step E20). When the end of input of the handwritten graphic is detected (step E22; Yes), the handwritten graphic 444 is adjusted to the size of the display size graphic 442 (step E24). For example, the position and area (size) on the touch panel 4 to which the handwritten figure 444 is input are detected, and the handwritten figure 444 is set so as to have a size substantially matching the handwritten figure in the area where the display size figure 442 is displayed. Zoom in or out.

  Then, the similarity score calculation unit 524 executes the similarity score calculation processing to calculate the similarity score (step E26). Then, the game calculation unit 520 evaluates the handwritten figure with respect to the model figure based on the calculated number of similar points, and executes an effect according to the evaluation result (step E28). For example, if the number of similar points is “80” or more, “I was imitated!” Is displayed on the main display unit 200 as a comment. Also, if the number of similar points is less than “80”, “Please look at the model carefully” is displayed on the main display unit 200 as a comment.

  Here, when an operation for ending the third game process is not detected from the user (step E30; NO), the game calculation unit 520 selects the next example figure. At this time, when the number of similar points is “60 points or more”, a sample figure that is more difficult than the current example figure is easier, and when the number of similar points is “less than 60 points”, it is easier than the current example figure. Are selected from the problem data 470 (step E32).

[3.4 Actions and effects]
As described above, according to the third embodiment, the model figure is composed of a combination of component figures. Therefore, it is not necessary to secure the storage capacity for storing the entire figure of each example figure in the storage unit 400, and more types of example figures can be stored. For example, as in the second embodiment, when determining the example figure that is most similar to the handwritten figure, it is better to store as many example figures as possible.

  Furthermore, the model figure is displayed on the main display unit 200 different from the sub display unit 220 on which the user performs handwriting input. For this reason, the user can give a new interest to the input form of the example figure, which is an operation of inputting the handwritten figure 444 while imitating the example figure while looking at the example figure. .

[3.5 Modification]
In the present embodiment, it has been described that the model graphic is displayed on the main display unit 200 when the user inputs the handwritten graphic 444. However, for example, input of the handwritten graphic 444 is started. After that, the model figure may be hidden. In this case, the user needs to remember the displayed example figure. So-called memory elements can be brought into the game, and new fun can be added to the game.

[Modification]
The preferred embodiments of the present invention have been described above, but the present invention is not limited to those described above, and can be changed as appropriate without departing from the spirit of the present invention.

  Although the game device of the above-described embodiment has been described as having the main display 5a and the sub display 5b as display devices, the display device may be only one display configured integrally with the touch panel. Of course. In this case, the game screen displayed on the main display 5a may be displayed on one side and the game screen displayed on the sub display 5b may be displayed on the other side by dividing the display vertically (or left and right).

  Further, although the evaluation table 446 has been described as being generated each time by the evaluation table generation unit 522, it may be stored in advance. For example, the first embodiment will be described as an example. In the storage unit 400, an evaluation table 446 corresponding to the example graphic 440a is stored in advance. Then, the game calculation unit 520 calculates the similarity score of the input handwritten figure 444 using the evaluation table 446 stored in advance. In this case, when the model figure 440a is selected, it is not necessary to generate the evaluation table 446 each time, and a higher speed operation can be expected.

[4.1 Determination of completion of handwriting input]
Moreover, although it demonstrated as a handwriting input being complete | finished when the touch operation input with respect to the end button by a user was made, when a predetermined condition is satisfy | filled, it is good also as terminating a handwriting input automatically. Hereinafter, a specific example thereof will be described based on the first embodiment.

[4.1.1 End determination based on the number of dots in a handwritten figure]
For example, in step A20 in FIG. 9, when the number of handwritten graphic dots is the same as the number of display size graphic dots, the handwriting input is terminated. In this case, since the user cannot input the handwritten figure 444 by handwriting to the end unless he / she writes more carefully, he / she tries to input it more carefully.

  For example, FIG. 29A shows an example of the game screen GW40 displayed on the sub display 5b. A model figure NZ40 is displayed on the game screen GW40. The user inputs the handwritten figure KZ40 by touching the sub display 5b with the touch pen PN. On the game screen GW40, the handwritten figure KZ40 is written with approximately the same size as the example figure NZ40.

  On the other hand, in the case of the game screen GW42 of FIG. 29B, the handwritten figure KZ42 is a figure larger than the model figure NZ42. Then, when the same number of drawing dots as the number of display size figure dots is displayed, the handwriting input ends. Therefore, in the game screen GW42 of FIG. 29B, the input of the handwritten figure KZ42 is not accepted halfway, and the process ends.

[4.1.2 Ending determination by game time]
The handwriting input may be terminated when a predetermined game time has elapsed. Specifically, task times are associated with each model figure 440a. And if handwriting input is started in step A18 of a 1st game process, it will start measuring the time of handwriting input. Then, when the timekeeping time coincides with the task time, the handwriting input is terminated. In this case, if the user carefully and slowly writes the figure, the task time elapses and the handwritten figure cannot be written until the end. Also, if you try to write early, the figure may become messy. In this way, the preference of the game can be further improved by providing the time limit.

[4.2 Figures have color information]
The model figure may have color information. Hereinafter, the case of having color information will be described based on the third embodiment.

  For example, it is assumed that the example graphic component configuration data 470b has “color” as the component graphic arrangement condition in addition to the conditions shown in FIG. For example, the colors include “black”, “red”, “blue”, “yellow”, etc., which are stored in association with each used component figure.

  FIG. 30 is a diagram illustrating an example of a game screen displayed on the game apparatus 1. Here, a model figure NZ44 is displayed on the game screen GW44. The example figure NZ44 is composed of four part figures, and each part figure is colored. For example, the circle NZ44a is colored black, the straight line NZ44b is red, the straight line NZ44c is blue, and the rectangle NZ44d is colored yellow.

  Then, the user inputs the handwritten figure KZ46 on the game screen GW46. Here, a color palette CP46 indicating each color is displayed on the right side of the game screen GW46. When each color of the color palette CP46 is touched with the touch pen PN, the color palette CP46 is input after touching the color palette CP46. The handwritten graphic is displayed in the touched color. For example, when the black palette CP46a is touched, the figure is colored black, when the red palette CP46b is touched, it is colored red, when the blue palette CP46c is touched, it is colored blue, and when the yellow palette CP46d is touched, it is colored yellow. The handwritten figure KZ46 displayed on the game screen GW46 is displayed by coloring the figure KZ46a in black, the figure KZ46b in red, and the figure KZ46c in blue.

  When the similarity score calculation unit 524 calculates the similarity score, if the dot color of the model figure and the dot color of the input figure match, for example, a score that is twice the evaluation score is similar. Add to the score. By doing in this way, the user can input a handwritten figure with a color, and the similarity changes according to the colored color, so that the interest of the game is improved.

[4.3 Changes in the number of similar points with game time]
Moreover, it is good also as adding a similar score according to the time which is performing handwriting input. For example, based on the third embodiment, the time required for handwriting input is measured in step E20. Then, bonus points are added to the number of similar points according to the measured time. For example, when the handwritten input time is less than “10” seconds, “20” points are added to the number of similar points, and when it is less than “30 seconds”, “10” points are added to the number of similar points. By adding bonus points according to the time of handwriting input in this way, the user tries to input handwritten figures quickly. . Since such a time factor can be disabled in the game, the interest of the game can be improved.

  Furthermore, the task time for the next game may be changed according to the number of similar scores. For example, when the number of similar points is high, the task time is shortened to increase the difficulty level, and when the number of similar points is low, the task time is lengthened to decrease the difficulty level.
