Description

Technical Field

[0001] This invention relates to learning aids. Background Technology

[0002] For example, with the increase in traffic accidents involving children during their commute to and from school, there is a need to seek an effective means of ensuring children's educational safety. Regarding traffic safety, for instance, International Publication 2019 / 240070 discloses a system in which a child-carried device detects values ​​related to the child's actions during their commute to and from school and sends these values ​​to a data center, which then evaluates the actions based on these values.

[0003] However, according to the system outlined in International Publication 2019 / 240070, because children are evaluated on their actions to and from school after returning home, and the results are communicated to the terminal, they only learn about the evaluation results after leaving the location where the actions were taken for traffic safety. Therefore, due to the lack of tangible feedback from the children regarding the evaluation results, learning effectiveness is low, and children struggle to develop traffic safety habits. Furthermore, this problem is not limited to learning actions for traffic safety; it also exists for learning other safety actions necessary to avoid accidents caused by the terrain on the way to school. Summary of the Invention

[0004] In view of this, the present invention has been made in view of the above-mentioned problems, and its object is to provide a learning aid device for improving learning effectiveness in safe actions.

[0005] The learning aid device of the present invention is carried by a learner who learns actions to ensure safety. The learning aid device includes: a determination unit that determines whether the learner has performed the action in a designated area; and a notification unit that promptly notifies the learner of the determination result after the determination unit's determination.

[0006] In the above structure, the notification unit can notify the learner of the determination result of the determination unit after the determination unit has made its determination, while the learner remains in the designated area.

[0007] In the above structure, the notification department may not notify the learner of the determination result of the learner's actions performed outside the designated area.

[0008] In the above structure, the notification unit can notify the learner of a first judgment message praising the learner when the determination unit determines that the learner has performed the above action.

[0009] In the above structure, the notification unit can notify the learner of a second determination message indicating that the learner has not performed the above action if the determination unit determines that the learner has not performed the above action.

[0010] In the above structure, the notification unit can select either the first mode or the second mode based on a random number when the learner arrives at the designated area. When the first mode is selected, an instruction message instructing the learner to perform the action will be sent to the learner. When the second mode is selected, no instruction message will be sent.

[0011] In the above structure, the notification unit can, when the determination unit determines that the learner has performed the above action, emphasize the determination result of the determination unit when the first mode is selected compared to when the second mode is selected.

[0012] In the above structure, there may be a storage unit that stores a table that records the determination results of the determination unit. The determination unit records the determination results of the determination unit in the table according to each of the specified areas. The notification unit modifies the random number based on the table so that the higher the frequency of the determination results of the determination unit that the learner has performed the above action, the higher the frequency of the first mode being selected.

[0013] In the above structure, the determination unit can determine whether the learner has taken the action to ensure traffic safety within the designated area.

[0014] According to the present invention, the learning effect of actions for safety can be improved. Attached Figure Description

[0025] (Structure and function of a traffic safety learning assistance system)

[0026] Figure 1 This is a structural diagram illustrating an example of a traffic safety learning assistance system (hereinafter referred to as "the System") 7. The System 7 includes a learning assistance device 1, a smartphone 2, and a recording server 3. The learning assistance device 1, smartphone 2, and recording server 3 are connected to a network 9, such as the Internet, and are able to communicate with each other via the network 9. The learning assistance device 1 and smartphone 2 communicate, for example, via wireless communication functions based on LTE (Long Term Evolution) or similar technologies.

[0027] Learning aid 1 is, for example, a portable device that enables a child to learn traffic safety actions (hereinafter referred to as "safety actions") when going to and from school. Reference numeral Ga is a simplified diagram of a child carrying learning aid 1. Learning aid 1 is, for example, a roughly rectangular badge-like device that is attached to the child's school hat H. Therefore, the child can easily carry learning aid 1 when going to and from school.

[0028] Furthermore, the installation location of the learning aid 1 is not limited to this; for example, it can be installed on the shoulder strap of a child's backpack or on a child's clothing. Additionally, the shape of the learning aid 1 is not limited; for example, it can be shaped like a wristwatch for installation on a child's arm.

[0029] Learning aid 1, for example, determines whether a child takes safe actions at multiple designated locations along their way to school. These designated locations include intersections, corners, and other places requiring attention in terms of traffic safety. Learning aid 1 records the historical data of the child's safe actions at each designated location, and periodically sends this historical data to a recording server 3.

[0030] The recording server 3 saves the historical records of security actions recorded by the learning assistance device 1 in a historical record database (DB) 30. The historical record database 30 is stored on the recording server 3's hard drive or solid-state drive, etc.

[0031] Smartphone 2 is a terminal owned by the parents of the child carrying learning aid 1. Smartphone 2 has a dedicated application (APP) 20 installed corresponding to learning aid 1. Based on the functions of APP 20, smartphone 2 sets a designated location for safe actions on learning aid 1. At this time, information about the designated location is sent from smartphone 2 to learning aid 1.

[0032] Additionally, smartphone 2 uses the functionality of application 20 to retrieve historical information about safety actions from the recording server 3. Application 20 displays the results of the child's safety actions, along with the child's movement path on a map, on the touch panel of smartphone 2.

[0033] The attached figure, labeled Gb, represents an example of the screen displayed on the touch panel of application 20. The screen displays a map 80 showing the child's route to and from school (dashed lines), the child's current location Po, designated locations P#1 to #3 for safety actions, and judgment results 81 to 83 at each designated location P#1 to #3.

[0034] For example, designated location P#1 corresponds to a T-junction area. As a safety action, it requires a temporary stop and confirmation of left and right sides. If the child has performed all the safety actions, then for the judgment result 81 of designated location P#1, both the temporary stop and the confirmation of left and right sides are "OK".

[0035] Additionally, designated location P#2 corresponds to the alleyway area, where slow walking (i.e., not running) is required for safety actions. If the child does not perform this safety action, the decision result 82 for designated location P#2 is "NG".

[0036] Additionally, designated location P#3 corresponds to a crossroads area, requiring a temporary stop and left / right confirmation for safety reasons. If the child temporarily stops but fails to confirm left / right, the decision result 83 for designated location P#3 is "OK" for the temporary stop, but "NG" for the left / right confirmation.

[0037] Therefore, parents can confirm the outcome of their child's safety actions through the screen on their smartphone 2. Furthermore, while this example exemplifies the child as a learner of safety actions, it is not limited to this; for instance, it could also be an elderly person traveling to and from the hospital.

[0038] (Structure of the learning aid device)

[0039] Figure 2This is a structural diagram showing an example of a learning aid device 1. The learning aid device 1 includes a control unit 40, an RTC (Real Time Clock) module 41, a GPS (Global Positioning System) module 42, a motion sensor unit 43, a speaker 44, and a communication processing unit 45.

[0040] RTC module 41 has calendar and clock functions. RTC module 41 outputs the year, month, day and time information used to generate the judgment history of security actions to control unit 40 according to the request from control unit 40.

[0041] The GPS module 42 detects the current position of the learning aid 1, i.e., the learner's current position Po, by receiving radio waves from GPS satellites. The GPS module 42 outputs the detected current position information to the control unit 40 upon request. In essence, the GPS module 42 is a position detection mechanism for detecting the learner's position.

[0042] The motion sensor unit 43 includes one or more sensors to detect the learner's movements. The motion sensor unit 43 includes, for example, an accelerometer and an angular velocity sensor. The motion sensor unit 43 outputs the detection values ​​from each sensor, such as acceleration and angular velocity, to the control unit 40 according to a request from the control unit 40. In essence, the motion sensor unit 43 is a motion detection mechanism that detects the learner's movements.

[0043] The speaker 44 outputs an audio message corresponding to the audio signal of the message input from the control unit 40. These audio messages include: an instruction message that instructs the learner to take a safe action when the learner's current position Po enters an area centered on designated positions P#1 to #3 with a radius of D (hereinafter referred to as the "designated area"); an OK judgment message that praises the learner if they have taken a safe action; and an NG judgment message that points out the situation if the learner has not taken a safe action.

[0044] The communication processing unit 45, for example, follows an LTE wireless communication circuit to process communications between the control unit 40, the recording server 3, and the smartphone 2 via the network 9. The communication processing unit 45 transmits data signals input from the control unit 40 to the network 9, and transmits data signals input from the network 9 to the control unit 40.

[0045] The control unit 40 determines whether the learner has performed a safety action at each designated location P#1 to #3, and notifies the learner of the corresponding decision result through the speaker 44. Here, the control unit 40 obtains the learner's current location Po from the GPS module 42 to determine whether the learner's current location Po is within the designated area. In addition, the control unit 40 obtains the learner's actions from the motion sensor unit 43 and uses them in the determination of safety actions.

[0046] Figure 3 This is a structural diagram illustrating an example of a control unit 40. The control unit 40 is, for example, a microcontroller, having a CPU (Central Processing Unit) 10, a ROM (Read Only Memory) 11, a RAM (Random Access Memory) 12, a storage memory 13, and an input / output port 14. The CPU 10 is connected to the ROM 11, RAM 12, storage memory 13, and input / output port 14 via a bus 19 to enable signal input and output between them. The control unit 40 is an example of a computer.

[0047] ROM11 stores the program that drives CPU10. RAM12 functions as the working memory of CPU10. Input / output port 14 transmits and receives various signals with, for example, RTC module 41, GPS module 42, motion sensor unit 43, speaker 44, and communication processing unit 45. CPU10 inputs and outputs signals with RTC module 41, GPS module 42, motion sensor unit 43, speaker 44, and communication processing unit 45 via input / output port 14.

[0048] If the CPU 10 reads a program from the ROM 11, it will form a management unit 100, a setting processing unit 101, an information acquisition unit 102, a security action determination unit 103, a message output unit 104, and a history record transmission unit 105. Additionally, the storage memory 13 stores a security action management table (TBL) 130, a message table (TBL) 131, and a determination result history record table (TBL) 132. Flash memory can be used as the storage memory 13, but it is not limited to it.

[0049] The management unit 100 manages the overall operation of the learning aid device 1. The management unit 100 instructs the settings processing unit 101, information acquisition unit 102, security action determination unit 103, message output unit 104, and historical record transmission unit 105 to perform actions according to the sequence set in the program.

[0050] The setting processing unit 101 receives setting information for designated locations P#1 to #3 from the smartphone 2 via the input / output port 14. The setting information may include not only the designated locations P#1 to #3, but also the category of security actions (left / right confirmation, etc.) for each designated location P#1 to #3. The setting processing unit 101 sets the security action management table 130 based on the setting information.

[0051] Figure 4 This is a diagram illustrating an example of Safety Action Management Table 130. Safety Action Management Table 130 records designated locations P#1 to #3 and the required safety actions, i.e., actions the learner should take at designated locations P#1 to #3, such as temporary cessation, left and right confirmation, and slow walking. Here, designated locations P#1 to #3 are based on GPS longitude and latitude values. Safety Action Management Table 130 is referenced when the learner's current location Po reaches the designated area and is used in determining safety actions.

[0052] If referred again Figure 3 The information acquisition unit 102 obtains various information from the RTC module 41, GPS module 42, and motion sensor unit 43 via the input / output port 14. The information acquisition unit 102 obtains date and time information from the RTC module 41. Additionally, the information acquisition unit 102 obtains latitude and longitude information from the GPS module 42 as location information representing the learner's current location Po, and obtains various detection values ​​related to the learner's movements from the motion sensor unit 43.

[0053] The safety action determination unit 103 is an example of a determination unit. When the learner's current position Po reaches the vicinity of designated positions P#1 to #3, it determines whether the learner has performed a safe action within the designated area based on the detection results of the motion sensor unit 43. For example, if the detection value of the angular velocity sensor changes continuously beyond a predetermined value in both the positive and negative directions, the safety action determination unit 103 determines that the learner has performed a left-right check. Conversely, if the detection value of the accelerometer sensor is below a predetermined value, the safety action determination unit 103 determines that the learner has stopped or is walking at a low speed.

[0054] The determination method of the safety action determination unit 103 is not limited to the above, and an appropriate method can be adopted depending on the type of sensor of the motion sensor unit 43 and the installation position of the learning aid device 1. For example, a small camera can be set as the motion sensor unit 43. In this case, the motion sensor unit 43 determines the safety action based on the image captured by the small camera. Alternatively, the GPS module 42 can be used together with the motion sensor unit 43 as a motion detection mechanism in the determination of the safety action. In this case, the safety action determination unit 103 can determine whether the learner has stopped or is walking at a low speed based on the displacement of the current position Po detected by the GPS module 42 at the time corresponding to the time.

[0055] If the safety action determination unit 103 determines that the learner has performed a safety action, the message output unit 104 outputs an OK judgment message praising the learner from the speaker 44. If the safety action determination unit 103 determines that the learner has not performed a safety action, the message output unit 104 outputs an NG judgment message from the speaker 44 informing the learner of the failure to perform a safety action. For example, the OK judgment message could be "Well done.", and the NG judgment message could be "Next time, you need to check left and right (stop temporarily, walk slowly (low speed))."

[0056] After the security action determination unit 103 makes its determination, the message output unit 104 promptly notifies the learner of its determination result. For example, if a determination result is obtained from the security action determination unit 103, the management unit 100 instructs the message output unit 104 to output an OK determination message as the determination result within the time required for the learner to leave the designated area. Here, the message output unit 104 is an example of a notification unit, the OK determination message is an example of a first determination message, and the NG determination message is an example of a second determination message.

[0057] Therefore, after a safe action is determined, the learning aid 1 can immediately notify the learner of the result. Thus, taking a child as an example, on their way to or from school, because they hear the "OK" message immediately after taking a safe action, they can perceive their action as correct and experience high satisfaction. However, if the child hears the "OK" message after leaving the designated area and returning home, because the actual feeling of the safe action's result is weak, they will only experience low satisfaction.

[0058] Furthermore, when a child leaves the designated area without performing the safety action, the immediate NG (Not Given) message makes them aware that they forgot the safety action, leaving a strong impression of regret. Conversely, if a child hears the NG message after leaving the designated area and returning home, the actual impact of the safety action decision is less significant, resulting in less regret for forgetting it. Adult learners also experience the same effects.

[0059] Therefore, the learning aid device 1 in this example can improve the learning effect of actions for traffic safety.

[0060] Thus, since the learning aid 1 notifies the learner of an OK or NG judgment message regarding safe actions, in the case of a learner, such as a child, it can be assumed that safe actions will be taken primarily for fun even outside designated areas. There is a concern that a child might intentionally make left and right checks, for example, even on a path where left and right checks are not required. If the learning aid 1 is assumed to notify the learner of such judgment messages regarding safe actions outside designated areas, there is a concern that it will be difficult to cultivate the habit of appropriately performing safe actions within designated areas where such actions are necessary.

[0061] Therefore, the message output unit 104 does not notify the learner of the determination result of the safety action performed outside the designated area. At this time, if the learner's current position Po is outside the designated area, the safety action determination unit 103 stops determining the safety action. Therefore, since the OK determination message and NG determination message are not notified to the learner as the determination result of the safety action outside the designated area, the learning aid device 1 enables the learner to more effectively learn the habit of properly performing safety actions in the designated area where safety actions are required.

[0062] Furthermore, when the learner's current position Po reaches the designated area, the message output unit 104 selects either an easy mode or a hard mode with different learning difficulties based on a random number. The easy mode is an example of the second mode, and the hard mode is an example of the first mode. The learning difficulty of the easy mode is lower than that of the hard mode at the point where the learner is instructed on safe actions in advance.

[0063] When the easy mode is selected, the message output unit 104 outputs an instruction message from the speaker 44 to the learner, instructing them on safe actions. The instruction message could be, for example, "Check left and right (stop temporarily, walk slowly)." Therefore, the learner can hear the instruction message and think of taking safe actions. On the other hand, when the difficult mode is selected, the message output unit 104 does not output an instruction message to the learner. In this way, since the easy mode with instruction messages and the difficult mode without instruction messages can be randomly selected, the learner cannot always rely on the instruction messages, thus improving their awareness of safe actions.

[0064] Furthermore, the message output unit 104 differentiates the content of the OK determination message based on whether the action is in easy or difficult mode. For example, if the safety action determination unit 103 determines that the learner has performed a safety action, the message output unit 104 emphasizes the OK determination message when selecting difficult mode compared to easy mode. In other words, the message output unit 104 notifies the learner of the OK determination message when selecting difficult mode compared to easy mode.

[0065] For example, message output unit 104 emphasizes the OK judgment message statement in hard mode compared to easy mode. For instance, if the OK judgment message in easy mode is "Well done.", the OK judgment message in hard mode could be "Excellent." Therefore, learners who hear the OK judgment message experience greater satisfaction in hard mode than in easy mode. Furthermore, the OK judgment messages in easy and hard modes can differ not only in statement but also in volume and frequency.

[0066] Figure 5 This is a diagram showing an example of message table 131. The message output unit 104 reads the setting data of the appropriate message from message table 131 and outputs the various messages described above by outputting the sound signal to speaker 44.

[0067] Message table 131 records the category, action mode, volume, number of outputs, and message. Within the message, the "****" section contains statements corresponding to the safety action (e.g., confirm left / right, temporarily stop, walk slowly).

[0068] For OK judgment messages, as mentioned above, the message wording differs between easy and hard modes. Furthermore, the volume of the OK judgment message is "normal" in easy mode, while it is set to "high" in hard mode. Also, the number of OK judgment messages is "1" in easy mode, while it is set to "2" in hard mode. The volume and number of NG judgment messages are set to "normal" and "1" respectively.

[0069] If referred again Figure 3 The security action determination unit 103 records the determination result of the security action in the determination result history table 132 according to each designated position P#1 to #3. The security action determination unit 103 obtains the year, month, day and time information from the RTC module 41 via the input / output port 14 and records it as date and time in the determination result history table 132. The determination result history table 132 is an example of a table that records the determination results of the security action determination unit 103, and the storage memory 13 is an example of a storage unit. The storage unit is not limited to the storage memory 13, and other information storage mechanisms can also be used.

[0070] Figure 6 This is a diagram illustrating an example of the judgment result history table 132. The judgment result history table 132 records the date and time, specified location, security action, and judgment result. As described above, the date and time are obtained from the RTC module 41. The specified location and security action are obtained from the security action management table 130.

[0071] If the learner is determined to have performed a safety action within the designated area corresponding to the specified locations P#1 to #3, the result is "OK". If the learner is determined not to have performed a safety action within the designated area corresponding to the specified locations P#1 to #3, the result is "NG".

[0072] If referred again Figure 3 The historical record sending unit 105 periodically reads the judgment result historical record table 132 from the storage memory 13 and outputs it to the communication processing unit 45 via the input / output port 14. The communication processing unit 45 sends the judgment result historical record table 132 as historical record information to the recording server 3.

[0073] Furthermore, the message output unit 104 modifies the random number used in selecting between the easy mode and the hard mode based on the decision result history table 132. As an example, the message output unit 104 determines the probability of selecting the hard mode (hereinafter referred to as the "selection probability") based on the ratio of the number of "OK" decision results to the total number of decision results in the decision result history table 132. For example, when the ratio of the number of "OK" decision results is 0.1, the selection probability of the hard mode is 0.1, and when the ratio of the number of "OK" decision results is 0.5, the selection probability of the hard mode is 0.5.

[0074] In this way, the message output unit 104 corrects the random number based on the judgment result history table 132, so that the higher the frequency of the "OK" judgment result, the higher the frequency of selecting the difficult mode. Therefore, for learners, the higher their mastery of security actions, the fewer opportunities they will hear instruction messages in the designated area, which can further improve their mastery.

[0075] (Actions of the control department)

[0076] Next, the operation of the control unit 40 will be explained. In the control unit 40, after the management unit 100 instructs the setting processing of the security action management table 130 to the setting processing unit 101, it instructs the information acquisition unit 102 to process the acquisition of various information from the RTC module 41, the GPS module 42 and the motion sensor unit 43, and instructs the security action determination processing and result output processing to the security action determination unit 103 and the message output unit 104 respectively.

[0077] Figure 7 This is a flowchart illustrating an example of information retrieval and processing. For instance, this process is executed repeatedly according to a predetermined cycle.

[0078] The information acquisition unit 102 obtains the date and time information from the RTC module 41 (step St1). Next, the information acquisition unit 102 obtains the learner's current location Po from the GPS module 42 (step St2). The current location Po is represented, for example, by latitude and longitude.

[0079] Next, the information acquisition unit 102 acquires various detection values ​​related to the learner's movements from the motion sensor unit 43 (step St3). Examples of detection values ​​include acceleration and angular acceleration, but it is not limited to these. The values ​​can be appropriately determined based on the installation location of the learning aid 1 and the type of safe action to be taken by the learner.

[0080] Figure 8 This is a flowchart illustrating an example of a process for instructing a safety action. This process, for example, begins at the start of a child's commute to or from school and ends at the end of the commute.

[0081] The management unit 100 reads the security action management table 130 from the storage memory 13 (step St11). The security action management table 130 was preset from the parent's smartphone 2. The management unit 100 outputs various information obtained by the information acquisition unit 102 to the security action determination unit 103 and the message output unit 104 as needed.

[0082] Next, the management unit 100 selects one of the designated locations P#1 to #3 from the security action management table 130 (step St12). Next, the management unit 100 instructs the security action determination unit 103 and the message output unit 104, respectively, on the determination processing and result output processing of the security action at the selected designated location P#1 to #3 (step St13).

[0083] Next, the management unit 100 determines whether all designated locations P#1 to #3 in the Safety Action Management Table 130 have been selected (step St14). If there are unselected designated locations P#1 to #3 (No in step St14), the management unit 100 selects the next designated location P#1 to #3 (step St12). Then, steps St13 and St14 are executed again. Here, the management unit 100 selects designated locations P#1 to #3, for example, in the order along the children's route to and from school.

[0084] In addition, once all designated locations P#1 to #3 have been selected ("Yes" in step St14), the management department 100 ends the process.

[0085] Figure 9 This is a flowchart illustrating an example of the determination and output of a security action. This process is performed according to the instructions in step St13 above. The instructions are assigned to designated positions P#1 to #3 in the Security Action Management Table 130.

[0086] The message output unit 104 calculates the distance D between the current position Po and the selected designated positions P#1 to #3 (step St21). Next, the message output unit 104 compares the distance D with a threshold Dth (step St22). Thus, the message output unit 104 determines whether the learner's current position Po has reached the designated area. The threshold Dth is, for example, the value for each designated position P#1 to #3, and can be determined based on various conditions of the designated positions P#1 to #3, such as the size of the intersection.

[0087] If the distance D is greater than the threshold Dth (No in step St22), the message output unit 104 executes the processing of step St21 again. That is, if the learner's current position Po is outside the designated area, even if the learner takes a safety action, the message output unit 104 will not output its judgment message. Therefore, learners can more effectively learn the habit of properly taking safety actions within the designated area where safety actions are required.

[0088] Furthermore, if the distance D is below the threshold Dth ("Yes" in step St22), the message output unit 104 reads the judgment result history table 132 (step St23). Next, the message output unit 104 adjusts the selection probability of the action mode based on the judgment result history table 132 (step St24). As described above, the message output unit 104 corrects the random number so that the higher the frequency of the "OK" judgment result, the higher the frequency of selecting the difficult mode.

[0089] Next, the message output unit 104 selects an action mode based on a random number (step St25). If the easy mode is selected ("Yes" in step St26), the message output unit 104 outputs an instruction message indicating a safety action from the speaker 44 based on the message table 131 (step St27). That is, the message output unit 104 notifies the learner of the instruction message. As a result, the learner is able to recall the safety action.

[0090] Furthermore, when the hard mode is selected (No in step St26), the message output unit 104 does not output an instruction message. That is, the message output unit 104 does not notify the learner of the instruction message. Therefore, the learner needs to take safety actions spontaneously without relying on the instruction message.

[0091] Next, the safety action determination unit 103 analyzes the learner's actions based on the detection values ​​from the motion sensor unit 43 (step St28). Then, based on the results of the action analysis, the safety action determination unit 103 determines whether the learner has performed a safety action corresponding to the selected designated positions P#1 to #3 (step St29). For example, the safety action determination unit 103 determines whether the learner has temporarily stopped and checked left and right within the designated area of ​​the designated position P#1 based on acceleration and angular acceleration.

[0092] When the safety action determination unit 103 determines that the learner has performed a safety action ("Yes" in step St29), and the easy mode is selected ("Yes" in step St30), the message output unit 104 outputs an OK determination message corresponding to the easy mode based on message table 131 (step St31). Conversely, when the difficult mode is selected ("No" in step St30), the message output unit 104 outputs an OK determination message corresponding to the difficult mode based on message table 131 (step St32). In other words, the message output unit 104 notifies the learner of the OK determination message. As described above, since the OK determination message corresponding to the difficult mode is emphasized more than the OK determination message corresponding to the easy mode, the learner can obtain a higher level of satisfaction.

[0093] At this time, for example, after the determination by the safety action determination unit 103 (step St29), the management unit 100 instructs the message output unit 104 to quickly output an OK determination message. For example, if the management unit 100 receives a safety action determination result (there is a safety action) from the safety action determination unit 103, it instructs the message output unit 104 to output an OK determination message within the time required for the learner to walk out of the designated area. Furthermore, the management unit 100 can either pre-store the required time as a fixed value, or calculate the learner's average movement speed based on the change in current position Po per unit time, and calculate the required time based on the average movement speed and current position Po.

[0094] Therefore, while the learner remains within the designated area, the message output unit 104 notifies the learner of the security action's determination result. Thus, because the learner hears the OK determination message immediately after completing the security action, the learning effect is improved.

[0095] Furthermore, if the safety action determination unit 103 determines that the learner has not performed a safety action (No in step St29), it calculates the distance D between the current position Po and the selected designated positions P#1 to #3 (step St34). Next, the message output unit 104 compares the distance D with the threshold Dth (step St35). Thus, the message output unit 104 determines whether the learner's current position Po is within the designated area.

[0096] If the distance D is below the threshold Dth (Yes in step St35), the safety action determination unit 103 re-analyzes the learner's action (step St28). Then, the subsequent processes are executed.

[0097] Additionally, if the distance D is greater than the threshold Dth (No in step St35), the message output unit 104 outputs an NG determination message (step St36). That is, the message output unit 104 notifies the learner of the NG determination message.

[0098] At this time, for example, after the determination by the safety action determination unit 103 (step St29), the management unit 100 instructs the message output unit 104 to quickly output an NG determination message. For example, after the management unit 100 receives a safety action determination result (no safety action) from the safety action determination unit 103 and determines that the learner's current position Po is outside the designated area ("No" in step St35), it instructs the message output unit 104 to output an NG determination message within a specified time (e.g., within 5 seconds).

[0099] In this way, if the learner moves outside the designated area without taking a safety action, the message output unit 104 quickly outputs an NG (Not Taken) judgment message. Therefore, after the child leaves the designated area without taking a safety action, they can immediately hear the NG judgment message and realize that they have forgotten to take a safety action.

[0100] Next, the security action determination unit 103 records the determination result of the security action in the determination result history table 132 (step St33). The determination result history table 132 is used in the selection of the action mode and the confirmation of the determination result of the security action involving the smartphone 2.

[0101] In this way, after the learner's safe actions in each designated area are determined, the learning assistance device 1 can immediately notify the learner of the OK and NG judgment messages as the judgment results. Therefore, the learning assistance device 1 in this example can improve the learning effect of actions for traffic safety.

[0102] Furthermore, in this example, the speaker 44 is cited as a means of conveying various messages to the learner, but the messages are not limited to sound. For example, a display can be cited as a means of conveying messages in text. In this case, the message output unit 104 can emphasize the OK decision message in the difficult mode compared to the OK decision message in the easy mode by changing the size of the text.

[0103] Alternatively, light-emitting devices such as LEDs (Light Emitting Diodes) can be used as mechanisms for transmitting messages using light. In this case, the message output unit 104 can emphasize the OK decision message in the difficult mode compared to the OK decision message in the easy mode by changing the intensity of the light.

[0104] Furthermore, as a mechanism for transmitting messages via vibration, a vibration generating device such as a vibration motor can be cited. In this case, the message output unit 104 can emphasize the OK decision message in the difficult mode compared to the easy mode OK decision message by changing the intensity of the vibration.

[0105] As described so far, the learning aid device 1 according to this example can effectively assist learners in learning safe actions to ensure traffic safety. However, the learning aid device 1 is not limited to traffic safety; it can also be a device that assists in learning safe actions to ensure safety in the event of an accident caused by the terrain of the school route. In this case, designated locations P#1 to P#3 can be designated, such as roads near steep slopes, and the safe action determination unit 103 can determine whether the learner is walking at a low speed in that designated area. Thus, the application of the learning aid device 1 is not limited.

[0106] The above-described embodiments are preferred embodiments of the present invention. However, they are not limited thereto, and various modifications can be made without departing from the spirit of the present invention.
