Users who use the present invention are assumed to be an operator who operates an information terminal and a player who draws a trajectory. The operator and the player may be the same person or may be different persons. For example, in a case where a parent lets a young child play, the parent may operate an information terminal as an operator, and the child may draw a trajectory as a player. If the child is old enough to go to school, it is conceivable that the child serves both as the operator and the player.

The operator or player confirms the line drawing displayed on the screen of the information terminal. The operator performs an operation on the information terminal to start trajectory acquisition, and the player moves while holding the information terminal equipped with a sensor such as an acceleration sensor so as to draw the same figure as the line drawing.
When the player returns to the point where the trajectory acquisition started, the operator performs an operation on the information terminal to end the trajectory acquisition. The information terminal that has completed the locus acquisition provides a game experience to the player by displaying the matching rate between the line drawing and the trajectory so that the two can be compared so that they can be visually recognized, and by converting the matching rate into points.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that each figure is merely shown schematically to the extent that the present invention can be fully understood. Therefore, the present invention is not limited to the illustrated example. Further, in each figure, common or similar components are denoted by the same reference numerals, and redundant explanation thereof will be omitted.

<Embodiment 1>
FIG. 1 is a system diagram showing an example of the configuration of the information terminal 1. As shown in FIG.
The information terminal 1 of the first embodiment includes a CPU (Central Processing Unit) 100, a ROM (Read Only Memory) 110, an acceleration sensor 120, an angular acceleration sensor 130, a geomagnetic sensor 140, a speaker 150, a touch panel display 160, and a RAM (Random Access Memory). ) 170 and a flash memory 180. These configurations are known configurations that information terminals generally have.

The CPU 100 executes programs stored in the flash memory 180 and the ROM 110, which is a read-only nonvolatile memory, and reads and writes data using the RAM 170, which is a volatile memory that can be read and written at high speed, as a work area.
The flash memory 180 is a readable and writable nonvolatile memory, and stores a movement trajectory detection program 181. Details of the movement trajectory detection program 181 will be explained later with reference to FIGS. 2 to 6.

The acceleration sensor 120, the angular acceleration sensor 130, and the geomagnetic sensor 140 are movement information acquisition means (movement information acquisition unit) of the information terminal 1.
The acceleration sensor 120 is a sensor that measures the acceleration of the information terminal 1 in three axes, and can measure not only the acceleration caused by the movement of the player holding the information terminal 1 but also the gravitational acceleration.
The angular acceleration sensor 130 is a type of inertial sensor and measures the angular acceleration of the information terminal 1 in three axes.
The geomagnetic sensor 140 measures the direction in which the information terminal 1 is facing by detecting the geomagnetism.
Since the movement information acquisition means can acquire changes in the position information of the information terminal 1, the movement information acquisition means is also referred to as position information acquisition means.

The speaker 150 operates as a notification means for notifying an operator or a player of information through sound.
The touch panel display 160 is a screen of the information terminal 1, and is made by laminating a transparent touch panel on a liquid crystal display or an organic EL display, for example, and operates as a display operation means.
Note that this embodiment can operate without using the angular acceleration sensor 130 and the speaker 150 of the above configuration.
However, if angular acceleration information is obtained using the angular acceleration sensor 130, more accurate movement information can be obtained. The information terminal 1 may be equipped with a sensor other than the above as a movement information acquisition means to obtain even more accurate movement information.
Moreover, if the information is announced using the speaker 150, it is possible to attract the user's attention more than when the information is notified only by changes in the screen.

In this way, if the information terminal 1 is equipped with a movement information acquisition means, the operator or player does not need to prepare a separate terminal equipped with the movement information acquisition means, and can easily draw a trajectory. It can be performed.

FIG. 2A is a schematic diagram of the movement start screen 500 of the first embodiment.
The CPU (line drawing display unit) 100 displays a movement start screen 500 as shown in FIG. 2A on the touch panel display 160 of the information terminal 1 by executing the movement trajectory detection program 181. A line drawing 300, an initial message 501, an acquisition start button 201, and a starting point icon 600 are displayed on the movement start screen 500.

The line drawing 300 is drawn based on data obtained from the network or data stored in the flash memory 180 or the like. The CPU 100 may have a line drawing changing function that changes the displayed line drawing 300 when the operator or player wishes to use a different line drawing. If there is a line drawing change function, the operator can select a line drawing with a difficulty level that corresponds to the player's ability. The line drawing change function may display line drawings at random, or may allow the operator to select a line drawing from a plurality of candidate line drawings.
The starting point icon 600 is an icon indicating the starting point for drawing the line drawing 300.
In the initial message 501, content prompting the start of measurement of the movement trajectory is displayed in accordance with the assumed age of the operator or player. Since the assumed age of the player is an infant, the initial message 501 displays the text ``Let's draw this picture on the water.''

When the operator taps the acquisition start button 201 at a certain point, the CPU 100 (trajectory information acquisition unit) transitions the screen to the trajectory information acquisition screen 510 (see FIG. 2B), and starts acquiring trajectory information from that point as the starting point. Start. The player moves while holding the information terminal 1 so that the locus of movement draws the figure of the line drawing 300.

FIG. 2B is a schematic diagram of the trajectory information acquisition screen 510 according to the first embodiment.
On the trajectory information acquisition screen 510, a line drawing 300, a trajectory information acquisition message 511, an acquisition end button 202, and a starting point icon 600 are displayed.
In the trajectory information acquisition message 511, content indicating that the trajectory is being acquired is displayed in accordance with the assumed age of the operator or player. Since the assumed age of the player is an infant, the text "Drawing in progress" is displayed in the message 511 in which trajectory information is being acquired.

The operator taps the acquisition end button 202 when the player finishes drawing the trajectory and returns to the starting point. The CPU 100 (calculation unit) that detects the tap on the acquisition end button 202 ends the acquisition of trajectory information, and calculates the trajectory image 400 based on the acquired trajectory information. After the calculation of the trajectory image 400 is completed, the CPU 100 (result display unit) changes the screen to a result screen 520 (see FIG. 2C).

FIG. 2C is a schematic diagram of the result screen 520 of the first embodiment.
The result screen 520 displays a line drawing 300, a trajectory image 400, a score 521, and a button 203.
Note that the result screen 520 only needs to display at least the line drawing 300, the trajectory image 400, and the button 203, and there may be a simple mode in which the score 521 is not displayed.

The line drawing 300 and the trajectory image 400 are displayed so that they can be compared in a manner that allows them to be distinguished so that the matching rate between the two can be easily recognized visually. In order to realize a mode in which they can be distinguished, for example, the color, thickness, and type of the lines drawn between the two may be changed and displayed. The line drawing 300 and the trajectory image 400 may be displayed overlappingly or side by side.
After the calculation of the trajectory image 400 is completed, the CPU 100 (determination unit) determines the matching rate between the line drawing 300 and the trajectory image 400 and converts it into a score. The CPU 100 (score display section) displays this score as a score 521 on the result screen 520. By converting the match rate into points, it is possible to provide the player with ways to play, such as aiming for a high score.

The button 203 is used to transition to the movement start screen 500 in order to start drawing the trajectory again. The button 203 is not limited to this, and may be used to terminate the movement trajectory detection program 181, or may have other functions, or may be a plurality of buttons.

FIG. 3 is a flowchart from when the CPU 100 of the first embodiment displays the movement start screen 500 on the touch panel display 160 of the information terminal 1 to when the result screen 520 is displayed.
First, the CPU 100 displays the movement start screen 500 (step S10). When the CPU 100 detects a tap on the acquisition start button 201 (step S11: Yes), the CPU 100 displays the trajectory information acquisition screen 510 (step S12).
Specifically, in step S10, when the operator taps the acquisition start button 201 on the movement start screen 500, a transition is made to the trajectory information acquisition screen 510. The player is given the information terminal 1 on which the acquisition start button 201 has been tapped by the operator, and starts moving. At this time, the player moves while holding the information terminal 1 in a fixed direction, such as by putting it in a pocket, rather than holding the information terminal 1 in his hand.

The CPU 100 continues to acquire movement information of the player and acquire trajectory information based on the movement information until detecting a tap on the acquisition end button 202 (step S13). Specifically, the CPU 100 acquires acceleration information from the acceleration sensor 120 and geomagnetic information from the geomagnetic sensor 140 of the information terminal 1 held by the player in a fixed orientation. The CPU 100 continues to acquire information on changes over time in the player's direction of movement, number of steps, and stride length information based on the geomagnetic information and acceleration information.
Note that at this time, the CPU 100 may obtain angular acceleration information from the angular acceleration sensor 130 or may obtain information obtained from other sensors. If these pieces of information are used together, more accurate trajectory information can be obtained.

When a tap on the acquisition end button 202 is detected (step S14: Yes), the CPU 100 ends the acquisition of the trajectory information, and calculates the shape of the trajectory image 400 based on the trajectory information (step S15).
Specifically, when the operator who receives the information terminal 1 from the player who has finished drawing the trajectory and returned to the starting point taps the acquisition end button 202 on the trajectory information acquisition screen 510, the CPU 100 executes the process in step S13. A trajectory image 400 is calculated based on the acquired trajectory information. That is, the CPU 100 calculates the trajectory image 400 by drawing a line corresponding to the moving distance based on the player's step length information and step count information in the direction of movement based on the information on changes over time in the direction of movement of the player.

Further, the calculation of the trajectory image 400 is performed on the premise that the acquisition end button 202 is tapped at the starting point.
Specifically, the player who receives the information terminal 1 from the operator who has already tapped the acquisition start button 201 starts drawing the trajectory from the operator's side, returns to the operator's side again, and operates the information terminal 1. and have the operator tap the acquisition end button 202.
Therefore, if the starting point and the ending point of the trajectory image 400 are different even though the starting point and the ending point of the line drawing 300 match, the CPU 100 determines that there is a measurement error and adjusts the trajectory so that the starting point and the ending point match. The angle and the like of the image 400 are corrected.
Furthermore, if the size of the trajectory image 400 is also corrected when calculating the trajectory image 400, it is possible to score the matching rate, which will be described later, based only on the shape, regardless of the size of the trajectory image 400.

After calculating the trajectory image 400, the CPU 100 performs scoring based on the matching rate between the line drawing 300 and the trajectory image 400 (step S16).
When scoring the matching rate, it is possible to score only the shape of the trajectory image 400 based on the trajectory image 400 whose start point, end point, and size have been corrected, or based on the trajectory image 400 whose start point and end point have been corrected. The shape and size of the trajectory image 400 may be scored based on the image 400.
By adding the match rate between the sizes of the trajectory image 400 and the line drawing 300 as a scoring element, it is possible to further improve the game performance.
When adding the size matching rate to the scoring element, the CPU 100 displays scale information indicating the correspondence between the line drawing 300 and the actual distance traveled on the movement start screen 500 in FIG. 2A and the trajectory information acquisition screen 510 in FIG. 2B. It's good to do that. By displaying the scale information, it is possible to encourage the player to perform a predetermined whole body exercise. For example, it is possible to move around a wide range to increase the amount of exercise, or to move around a narrow range depending on athletic ability.

After completing the matching rate scoring, the CPU 100 displays an image in which the line drawing 300 and the corrected trajectory image 400 are superimposed, the scoring results, etc. on the result screen 520 (step S17). Note that the CPU 100 may simply calculate the trajectory image 400 (step S15) and display the line drawing 300 and the corrected trajectory image 400 so that they can be compared.
If it takes time to calculate the trajectory image 400 or score the match rate, before displaying the result screen 520, you may transition to a screen that informs you of the progress of processing in the background, such as "Scoring", or A message containing the content may also be displayed. By notifying the progress of processing in the background, it is possible to eliminate the operator's and player's concerns about whether the program has frozen or the like.

In this way, the invention of Embodiment 1 can encourage the player to exercise the whole body by providing a game experience to the player by evaluating the match rate between the line drawing and the movement trajectory of the player.

<Modification of Embodiment 1>
As a modification of the first embodiment, a function may be added to change trajectory information depending on a specific movement of the player. By specifying a specific movement, the difficulty level of drawing the trajectory increases, making it possible to provide even more interest to the player.
The specific movement includes jumping, increasing/decreasing the movement speed, moving with a certain rhythm, etc., and a combination of these may also be specified.

FIG. 4A is a schematic diagram of a movement start screen 530 according to a modification of the first embodiment.
On the movement start screen 530, a line drawing 301 having a line drawing changing portion 302, an initial message 531, and a starting point icon 600 are displayed. This line drawing change portion 302 has thicker lines than other portions.
Note that the line drawing change portion 302 may be in any form as long as it can be distinguished from other portions. The display is not limited to changing the line thickness as in this embodiment, but can be displayed in various ways such as different colors, blinking, different line types, etc.

The initial message 531 displays content that informs the operator or player that the trajectory can be changed by a specific movement, in accordance with the assumed age of the operator or player.
For example, if the specific movement is a jump and the way the line drawing changes is the thickness of the line, the expected age of the player is an infant, so the initial message 531 reads, ``If you jump, the text will suddenly become thick.'' is displayed.

When the operator taps the acquisition start button 201 at a certain point, the CPU 100 changes the screen to a trajectory information acquisition screen 540 (see FIG. 4B) and starts acquiring trajectory information using the point as the starting point. While holding the information terminal 1, the player moves so that the locus of movement draws the figure of the line drawing 301, and performs a designated specific movement in an area corresponding to the line drawing changing portion 302.

Note that if the specific movement is a movement with a certain rhythm, the rhythm may be specified by the sound emitted by the speaker 150 of the information terminal 1. By specifying the rhythm using the sound emitted by the speaker 150, it is possible to provide the player with the entertainment of exercising in accordance with the rhythm of the sound.
Further, if the specific movement is a movement that increases or decreases the movement speed, the increase or decrease in the movement speed may be specified by a change in the tempo of the sound. By specifying an increase or decrease in the movement speed using the sound emitted from the speaker 150, the player can be intuitively informed of the specification of a specific movement.

FIG. 4B is a schematic diagram of a trajectory information acquisition screen 540 according to a modification of the first embodiment.
On the trajectory information acquisition screen 540, a line drawing 300 having a line drawing change portion 302, a trajectory information acquisition message 541, an acquisition end button 202, and a starting point icon 600 are displayed.

The operator taps the acquisition end button 202 when the player finishes drawing the trajectory and returns to the starting point. When the CPU 100 detects the tap on the acquisition end button 202, the CPU 100 ends the acquisition of trajectory information and calculates the trajectory image 400 based on the acquired trajectory information. After the calculation of trajectory image 400 is completed, CPU 100 changes the screen to result screen 550 (see FIG. 4C).

FIG. 4C is a schematic diagram of a result screen 550 of a modification of the first embodiment.
The result screen 550 displays a line drawing 301 having a line drawing change portion 302, a trajectory image 401 having a trajectory change portion 402, a score 551, and a button 203.

The trajectory change portion 402 is a trajectory of a section in which the player moves while performing a specified specific movement. The CPU 100 detects a movement made by the player while performing a specific movement based on acceleration information, etc., and draws a trajectory corresponding to the movement as a trajectory change portion 402 in the same manner as the line drawing change portion 302. Furthermore, in scoring the matching rate between the trajectory image 401 and the line drawing 301, it is also evaluated whether the changed portions match. By evaluating the matching rate of the changed parts, it is possible to increase the difficulty of the game and provide even more interest to the player.
Note that, similarly to the first embodiment, there may be a simple mode in which the score 551 is not displayed.

In this way, the modified example of Embodiment 1 increases the difficulty of the game by instructing the player to draw part of the trajectory while making a specific movement, and also evaluating this specific movement. , it is possible to provide even more interest to the player.

<Embodiment 2>
In addition to the functions of the first embodiment, the CPU 100 may have a function of abnormally terminating the acquisition when a predetermined time limit has elapsed after starting the acquisition of trajectory information. By setting a time limit, it is possible to provide the player with a way to play by completing the game within the time limit.

In the second embodiment, a warning time shorter than the time limit is provided, and when the warning time has elapsed, a warning to the effect that the time limit is approaching is notified to the operator or player. By reporting the warning, the player can take measures such as accelerating the drawing pace in order to complete the drawing within the time limit.
Specific means of notifying a warning include transitioning to a warning screen, changing only the message on the screen, and notifying by sound. good. In this embodiment, a warning is notified to the operator and the player by transitioning to a warning screen and sounding a warning sound.

In the present embodiment, the speaker 150 (see FIG. 1) of the information terminal 1 emits a sound effect (first sound) from the time acquisition of trajectory information is started until the acquisition of trajectory information is completed or abnormally terminated. Keep informing.

When the warning time has elapsed, the CPU 100 transitions to a warning screen 560 as shown in FIG. 5A having a warning message 561, and continues to notify the user with a warning sound (second sound) instead of the sound effect.
In the warning message 561, content notifying that the warning time has passed and the time limit is approaching is displayed in accordance with the assumed age of the operator or player. Since the assumed age of the player is an infant, the warning message 561 displays the text "You don't have much time!" as shown in FIG. 5A.

If the acquisition end button 202 is not tapped even after the time limit has elapsed, the CPU 100 displays an abnormal end screen 570 as shown in FIG. 5B on the touch panel display 160.
On the abnormal end screen 570, a message notifying that the time limit has passed is displayed in accordance with the assumed age of the operator or player. Since the assumed age of the player is a young child, the text "Zannen!" is displayed on the abnormal end screen 570 as shown in FIG. 5B.

FIG. 6 is a flowchart from when the CPU 100 of the second embodiment displays the movement start screen 500 on the touch panel display 160 of the information terminal 1 to when the result screen 520 or the abnormal end screen 570 is displayed.
First, the CPU 100 displays the movement start screen 500 (step S20). When the CPU 100 detects a tap on the acquisition start button 201 (step S21: Yes), the CPU 100 displays the trajectory information acquisition screen 510 (step S22).
Specifically, when the operator taps the acquisition start button 201 on the movement start screen 500, the trajectory information acquisition start condition is met, the CPU 100 starts acquiring trajectory information, and the screen transitions to the trajectory information acquisition screen 510. do. The player is given the information terminal 1 on which the acquisition start button 201 has been tapped by the operator, and starts moving.

As long as the time limit has not been exceeded (step S24: other than "time limit exceeded") and the tap of the acquisition end button 202 has not been detected (step S30: No), the CPU 100 collects the player's movement information. is acquired, and trajectory information is continued to be acquired based on the movement information (step S23). Furthermore, the CPU 100 continues to notify the sound effect (first sound) until the warning time is exceeded (step S24: less than the warning time) (step S29). The first sound is a sound that notifies that the CPU 100 is acquiring trajectory information. Furthermore, the first sound may have a rhythm or tempo that matches the specific movement of the modification of the first embodiment described above, and may intuitively convey the designation of the specific movement to the player.
Details of acquiring trajectory information are the same as in the first embodiment.

When the warning time is exceeded (step S24: longer than the warning time), the CPU 100 displays the warning message 561 (step S25), and further notifies the user with a warning sound (second sound) instead of the sound effect (first sound). The process continues (step S26).
Specifically, when the time limit is approaching and the player has not yet finished drawing the trajectory, the warning condition is met, the CPU 100 issues a warning sound (second sound), and the screen transitions to the warning screen 560. do. The player listens to this warning sound (second sound), increases his or her movement speed, and aims to complete the movement within the time limit. The second sound is a sound that warns the operator and the player that the time limit is approaching. By making the second sound a faster-tempo sound than the first sound, it is possible to increase the player's sense of urgency and make him hurry to clear the game within the time limit.

If the time limit elapses after the warning time is exceeded and before a tap on the acquisition end button 202 is detected (step S24: time limit exceeded), the CPU 100 stops the sound notification and displays the abnormal end screen 570 ( Step S28).
Specifically, when the player fails to return to the starting point within the time limit and the operator fails to tap the acquisition end button 202, the abnormal termination condition is met, and the CPU 100 issues a sound notification and acquires trajectory information. is terminated, and the screen transitions to an abnormal termination screen 570.
If a tap on the acquisition end button 202 is detected before the time limit elapses (step S30: Yes), the CPU 100 ends the acquisition of the trajectory information, stops the sound notification, and displays the trajectory image 400 based on the trajectory information. (See FIG. 2C) is calculated (step S31).
After calculating the trajectory image 400, the CPU 100 scores the matching rate between the line drawing 300 and the trajectory image 400 (step S32). The details of scoring the match rate are the same as in the first embodiment.

After completing the matching rate scoring, the CPU 100 displays an image in which the line drawing 300 and the calculated trajectory image 400 are superimposed, the scoring results, etc. on the result screen 520 (step S33). Details of display of scoring results and the like are the same as in the first embodiment.

In this way, the invention of the second embodiment increases the difficulty of the game by setting a time limit, making it possible to provide the player with even more interest.

<Embodiment 3>
Embodiment 3 will be described below as a more specific example of Embodiment 1.
FIG. 7 is a schematic diagram of a design selection screen 700 according to the third embodiment. The design selection screen 700 is a specific example of the line drawing changing function described in the first embodiment.

The design selection screen 700 displays a return button 204 and designs 701A to 701D that are the basis of line drawings drawn by the player. Although four designs are displayed in this embodiment, the number of designs may be greater or less than this. Further, although omitted in the figure, a message indicating that selecting a design will move to the movement start screen 580 (see FIG. 8A) may be displayed.

When the operator taps the return button 204, the CPU 100 transitions the screen to a game selection screen (not shown). On the game selection screen, various game applications can be selected in addition to the game application related to the movement trajectory detection program 181 of this embodiment.
When one of the designs 701A to 701D is tapped, a transition is made to a movement start screen 580 (see FIG. 8A) corresponding to the design.

The reason for having the operator select a design is as follows. In the game of this embodiment, since the trajectory is drawn by the player running around, it is difficult to draw complicated figures. Therefore, the operator selects a design, and a figure obtained by deforming this design is used as a line drawing to be drawn. For example, if the "house" design 701A is selected, a "pentagon" that is a deformed connection between the roof, walls, and foundation of the house is set as the line drawing 311 to be drawn (see FIG. 8A).

As a result, even if what the player actually draws is a simple figure such as a square or a triangle, the player can be made to feel that he is ``drawing a picture,'' and it is possible to provide further interest.

FIG. 8A is a schematic diagram of a movement start screen 580 corresponding to the design 701A of the third embodiment.
A line drawing 311, a stroke order 312, and a back button 204 are displayed on the movement start screen 580, and the stroke order 312 has a line drawing start point (S) 601 and a line drawing end point (G) 602 at both ends thereof. There is.
When the operator taps the return button 204, the CPU 100 changes the screen to the above-described design selection screen 700 (see FIG. 7).

The line drawing 311 is a line drawing corresponding to the design 701A selected in FIG. 7, that is, the "house" design, and is a pentagon that is a deformed form of the house.
The stroke order 312 indicates the direction in which the player should move in order to draw the trajectory, the line drawing start point 601 indicates the player's movement start point, and the line drawing end point 602 indicates the movement end point.

In this embodiment, a line drawing starting point 601 and a line drawing ending point 602 are adjacent to each other. By configuring the line drawings 311 as one continuous line in this way, it becomes easy to obtain the trajectory image 411 in FIG. 8B from the player's movement information without using GPS (Global Positioning System).

When the operator taps the acquisition start button 201, the CPU 100 changes the screen to a trajectory information acquisition in progress screen. This trajectory information acquisition screen has almost the same configuration as the trajectory information acquisition screen 510 (see FIG. 2B), so illustration thereof is omitted.
The player moves from the point corresponding to the line drawing starting point 601 toward the point corresponding to the line drawing ending point 602 as shown in the drawing order 312. In the example of this embodiment, the stroke order 312 indicates that the player should move clockwise. If the player draws a trajectory in the opposite direction, the trajectory image 411 is obtained upside down. The effect of this vertical reversal on the scoring of the trajectory image 411 will be described later with reference to FIG. 9.

When the operator taps the acquisition end button 202 on the trajectory information acquisition screen, the CPU 100 transitions the screen to a result screen 590 (see FIG. 8B). Note that, although this applies to all screen transitions, only a portion of the screen may be dynamically updated instead of transitioning the screen itself. For example, when the operator taps the acquisition end button 202, the lower part of the trajectory information acquisition screen may be expanded to display the trajectory image 411, shape evaluation 591, size evaluation 592, speed evaluation 593, and the like.

FIG. 8B is a schematic diagram of the result screen 590 of the third embodiment.
On the result screen 590, a trajectory image 411, a shape evaluation 591, a size evaluation 592, a speed evaluation 593, and a button 203 are displayed. Smoothing is performed when calculating the trajectory image 411. Smoothing will be described later.

In this embodiment, the evaluation results of each element such as the shape, size, and drawing speed of the trajectory image 411 are displayed as the evaluation results. The evaluation result of each element may be expressed as a percentage, such as shape evaluation 591, or as a score, such as size evaluation 592 or speed evaluation 593. Such a display allows the player to understand what to be careful about in order to aim for a high score in the next play, and can stimulate the player's ingenuity.

Although omitted in FIG. 8B, not only the evaluation results of each element are displayed using shape evaluation 591, size evaluation 592, and speed evaluation 593, but also the total score is displayed as in Embodiments 1 and 2. You may.
Furthermore, instead of the total score, several patterns of illustrations may be prepared, and the higher the total score, the more gorgeous the illustrations will be displayed.

Furthermore, the illustration displayed instead of the total score may be made to correspond to the design selected on the design selection screen 700. For example, if the "house" design 701A is selected as in this embodiment, an illustration of a "kennel" is displayed when the score is low, and an illustration of a "general house" is displayed when the score is medium. is displayed, and when the score is high, an illustration of a "castle" is displayed.
In this way, by displaying illustrations corresponding to the designs instead of the total score, it is possible to make the player feel that he has ``drawn a picture'', and it is possible to provide further interest.

FIG. 9 is a flowchart from when the CPU displays the movement start screen 580 to when the result screen 590 is displayed in this embodiment.
First, the CPU 100 displays the movement start screen 580 (step S40). As mentioned above, the stroke order 312 is shown on the movement start screen 580.

When the CPU 100 detects a tap on the acquisition start button 201 (step S41: Yes), the CPU 100 displays a trajectory information acquisition screen (not shown) (step S42). Specifically, in step S40, when the operator taps the acquisition start button 201 on the movement start screen 580, a transition is made to a trajectory information acquisition screen (not shown). The player is given the information terminal 1 on which the acquisition start button 201 has been tapped by the operator, and starts moving.

The CPU 100 continues to acquire the player's movement information and acquire the trajectory information based on the movement information until it detects a tap on the acquisition end button on the trajectory information acquisition screen (not shown) (step S43). The specific method for acquiring trajectory information is almost the same as in Embodiment 1, but in Embodiment 1, "information on changes over time in the player's direction of movement, information on the number of steps, and information on stride length" was acquired, but this In the embodiment, "information on changes over time in the player's direction of movement and information on the number of steps" is acquired. That is, in this embodiment, step length information is not acquired in real time.

If step length information acquired in real time is used to calculate the trajectory image 411 as in the first embodiment, the size of the trajectory image 411 can be calculated accurately.
However, the stride length of a person moving at a certain speed is approximately constant, and if there is stride length information with a fixed value input before the game starts, it is possible to calculate the size of the trajectory image 411 with sufficient accuracy for the game. It is also possible to do so. Therefore, a configuration may be adopted in which input of stride length information is required before the start of the game, or a value close to the player's stride length may be selected from among several pieces of stride length information.

Furthermore, since the player is assumed to be a child, and the difference in stride length between players is not considered to be large, even if the configuration has a predetermined fixed value for stride length information, the trajectory image 411 will be accurate enough for the game. It is also possible to calculate the size of . Therefore, in this embodiment, a prescribed fixed value is used as the stride length information. With such a configuration, the movement trajectory detection program 181 can be implemented more easily than when step length information is set individually.

When a tap on the acquisition end button on the trajectory information acquisition screen (not shown) is detected (step S44: Yes), the CPU 100 ends the acquisition of trajectory information and proceeds to calculate the trajectory image 411. Specifically, when the operator who received the information terminal 1 from the player who finished drawing the trajectory and returned to the starting point taps the acquisition end button on the trajectory information acquisition screen (not shown), the CPU 100: Calculation of the trajectory image 411 is started based on the trajectory information acquired in step S43.

The CPU 100 calculates the trajectory image 411 by drawing a line corresponding to the moving distance based on the player's step length information and step count information in the direction of movement based on the information on the change over time in the direction of movement of the player. Here, as a result of the inventors' actual operation and study of the invention, it was found that if the trajectory image 411 is simply calculated from the player's direction of movement and step count information, the lines of the trajectory image 411 will wobble and the figure will not be easy to see. It turns out that there are cases. Therefore, in this embodiment, smoothing processing is performed when calculating the trajectory image 411 (step S45).

The specific details of the smoothing process are as follows. In other words, if the angle between the acquired trajectories, that is, the angle formed by the direction of movement of one step of the player and the direction of movement of the next step, is within a predetermined value, the angle between the trajectories is the intended direction of movement. It is thought that this is not due to any changes. The angle between the trajectories is considered to indicate a blur caused by the fact that the information terminal 1 is unavoidably shaken because it is held by a moving player.

Therefore, when the angle between the trajectories is within a predetermined threshold, the CPU 100 of this embodiment calculates a moving average of the trajectory information for each predetermined number of steps, and connects the moving averages to create the trajectory image 411. Calculate. By calculating the trajectory image 411 in this way, it is possible to draw a smooth and easy-to-see trajectory image 411.
The predetermined number of steps can be set as appropriate, and can be set to about three steps, for example. Further, the predetermined threshold value of the angle between the trajectories may be set to a fixed value common to each line drawing, or may be set to a unique value for each line drawing.

For example, if the angle between the trajectories exceeds about 45 degrees, it can be assumed that the player intentionally crossed the direction of travel in order to create an angle in the trajectories. Therefore, the predetermined threshold value of the angle between the trajectories may be set to a fixed value of around 45 degrees. Such a configuration not only simplifies the implementation of the movement trajectory detection program 181, but also eliminates the need to set the angle each time a line drawing is added in the future, improving maintainability.
On the other hand, if a unique value is set for each line drawing, it becomes possible to use shapes in which lines are combined at shallow angles in the line drawing, which increases the variety of line drawings and improves the gameplay.

Here, as a result of actually operating and examining the invention, the inventors found that when the player taps the acquisition end button on the trajectory information acquisition screen (not shown), the player returns to the point corresponding to the line drawing end point 602 correctly. It has been found that there are cases in which a continuous trajectory image 411 is not calculated even though Therefore, in this embodiment, a trajectory image 411 is obtained by performing a correction process to match both ends of the trajectory image, that is, the trajectory start point and the trajectory end point (step S46). This correction method will be described later with reference to FIG.

The matching rate is evaluated for the trajectory image 411 (step S47). In this embodiment, tens to hundreds of patterns of correct trajectory images that can be drawn are stored in a server on a network through machine learning, and the CPU 100 compares these correct trajectory images with the trajectory image 411. , evaluate the shape matching rate and size matching rate. Furthermore, the speed at which the trajectory image 411 was drawn is also evaluated by comparing it with a specified value.

Note that, as described in the explanation regarding FIG. 8A, when the player draws a trajectory in the opposite direction to the stroke order 312, the trajectory image 411 is calculated upside down. The vertical direction of this trajectory image 411 may or may not be included in the shape evaluation 591.

If an upside-down trajectory image is included in the correct trajectory image pattern used for machine learning, it becomes possible to give a high score in the shape evaluation 591 as long as the shape matches even if the vertical direction is reversed. With such a configuration, it is possible to meet the need for children to play peacefully.

If an upside-down trajectory image is not included in the machine-learned correct trajectory image pattern, it is possible to evaluate a figure whose vertical direction does not match as a different figure and give a low score in the shape evaluation 591. With such a configuration, more complex figures can be registered as correct trajectory image patterns, and the gameplay can be further improved.
After performing the evaluation as described above, each element of shape evaluation 591, size evaluation 592, and speed evaluation 593 is displayed on the result screen 590 (step S48).

FIG. 10 is a schematic diagram of a method for correcting the trajectory image 411.
FIG. 10 shows a trajectory image 420 before correction, a trajectory image 430 after correction, a trajectory starting point 611, and a trajectory ending point 612. The correction length 620 indicates the amount of movement for transforming the trajectory image 420 before correction into the trajectory image 430 after correction.

It is considered that the discrepancy between the actual movement trajectory of the player and the trajectory image 420 before correction becomes larger cumulatively as the player's movement distance becomes longer. Therefore, in this embodiment, the shape of the entire trajectory image 420 before correction is corrected, instead of overlapping the trajectory starting point 611 and the trajectory ending point 612 by simply rotating the side having the trajectory end point 612 of the trajectory image 420 before correction. It shall be. Specifically, the shape of the entire trajectory image 420 before correction is corrected so that the correction length 620 becomes longer as it approaches the trajectory end point 612 rather than the trajectory start point 611.

Note that movement information acquisition means such as the acceleration sensor 120 and the geomagnetic sensor 140 may be installed in a terminal separate from the information terminal 1, and the player may move while holding the separate terminal.
If the player holds the movement information acquisition means as a separate terminal, there is no need for the player to hold the information terminal 1, and if the player, who is assumed to be an infant, falls or drops the information terminal 1, the information may be lost. Damage to the terminal 1 can be prevented.
