Description

The present invention relates to a learning support device.

For example, with the increase in traffic accidents involving children on their way to and from school, there is a demand for effective means of educating children about safety. For example, in relation to traffic safety, Patent Document 1 discloses a system in which a terminal carried by a child detects detection values related to the child's behavior on the way to and from school and transmits them to a data center, and the data center evaluates the behavior based on the detection values.

International Publication No. 2019/240070

In the above system, when a child approaches an intersection or the like, the terminal activates a vibrator to alert the child to their surroundings and to warn the child of their approach. The alert stops after the child takes the necessary action to ensure road safety.

However, for example, if a child stops at an intersection because the traffic light turns red after checking both sides, the device will stop notifying the child, which may lead to the child losing focus on safety, even though the traffic conditions at the intersection are changing. For this reason, it is difficult for the above system to help children fully learn how to behave safely. Note that this problem is not limited to learning how to behave for traffic safety, but also exists when it comes to learning other safety behaviors necessary to avoid accidents due to the topography of the school route, for example.

The present invention was made in consideration of the above problems, and aims to provide a learning support device that improves the effectiveness of learning safety behavior.

The learning support device of the present invention is a learning support device carried by a learner who is learning safety behaviors, and includes a notification unit that notifies the learner that the learner is in a designated area, and a judgment unit that judges whether the learner has performed the behavior in the designated area. The notification unit restricts the notification when the judgment unit judges that the learner has performed the behavior, and lifts the restriction on the notification when the learner remains in the designated area for a predetermined period after the restriction on the notification.

In the above configuration, if the learner remains in the designated area for the predetermined period after the notification is restricted, the notification unit may release the notification restriction in response to the learner starting to move.

In the above configuration, the notification unit may cancel the notification restriction if the learner remains in the designated area for the predetermined period after the notification restriction.

In the above configuration, the notification unit may cancel the notification restriction if the determination unit determines that the learner remains in the designated area for the predetermined period after the notification restriction and that the learner has not performed the behavior.

In the above configuration, the notification unit may restrict the notification if the learner moves outside the designated area after the restriction on the notification is lifted.

In the above configuration, the notification unit may stop the notification when the determination unit determines that the learner has performed the action, and may resume the notification when the learner remains in the designated area for the predetermined period after the notification is stopped.

In the above configuration, the determination unit may determine whether the learner has performed the behavior that ensures traffic safety within the specified area.

The present invention can improve the effectiveness of learning safety behavior.

(Configuration and functions of the traffic safety learning support system)
1 is a configuration diagram showing an example of a traffic safety learning support system (hereinafter, referred to as "system") 7. The system 7 includes a learning support device 1, a smartphone 2, and a record server 3. The learning support device 1, the smartphone 2, and the record server 3 are connected to a network 9 such as the Internet, and can communicate with each other via the network 9. The learning support device 1 and the smartphone 2 communicate with each other using a wireless communication function based on, for example, LTE (Long Term Evolution) or the like.

The learning support device 1 is a portable device that teaches children, for example, how to ensure traffic safety when going to and from school (hereinafter referred to as "safety behavior"). Symbol Ga is a schematic diagram of a child carrying the learning support device 1. The learning support device 1 is, for example, a roughly rectangular badge-type device that is attached to the child's school hat H. This allows the child to easily carry the learning support device 1 when going to and from school.

The attachment position of the learning support device 1 is not limited to this, and it may be attached to the shoulder strap of a child's school bag, for example, or to the child's clothing. There is also no limitation on the shape of the learning support device 1, and it may be shaped like a wristwatch so that it can be attached to a child's arm, for example.

The learning support device 1 judges whether or not a child is behaving safely at multiple designated locations, for example, on a route to school. The designated locations are locations where traffic safety precautions are required, such as intersections and corners. The learning support device 1 records a history of judgments on whether or not a child is behaving safely at each designated location, and transmits this, for example, periodically to the recording server 3 as history information.

The recording server 3 stores the safety behavior judgment history recorded by the learning support device 1 in a history database (DB) 30. The history database 30 is stored on a hard disk drive or solid state drive of the recording server 3.

The smartphone 2 is a terminal owned by the parent of the child who carries the learning support device 1. A dedicated application (APP) 20 compatible with the learning support device 1 is installed on the smartphone 2. Based on the function of the application 20, the smartphone 2 sets, for example, a designated position for safety behavior for the learning support device 1. At this time, information on the designated position is sent from the smartphone 2 to the learning support device 1.

The smartphone 2 also acquires history information on safe behavior from the recording server 3 based on the function of the application 20. The application 20 displays the judgment result of the child's safe behavior on the touch panel of the smartphone 2 together with the child's movement route on a map.

The symbol Gb indicates an example of a touch panel screen displayed by the application 20. The screen displays a map 80 showing the child's route (dotted line) to and from school, the child's current position Po, designated positions P#1 to #3 for safety actions, and the judgment results 81 to 83 at each of the designated positions P#1 to #3. Note that in this example, the safety action includes, but is not limited to, checking for traffic safety.

For example, the designated position P#1 corresponds to a T-junction area, and checking left and right is required as a safety precaution. If the child checks left and right, the judgment result 81 for the designated position P#1 becomes "OK."

The designated location P#2 is in a T-junction area, and as a safety precaution, the child must check to the right. If the child does not check, the judgment result 82 for the designated location P#2 will be "NG."

The designated position P#3 is in a crossroads area, and checking left and right is required as a safety precaution. If the child checks left and right, the judgment result 83 for the designated position P#3 will be "OK."

Therefore, parents can check the results of their children's safety behavior through the screen of the smartphone 2. Note that in this example, children are given as learners of safety behavior, but this is not limited to this, and could also be, for example, an elderly person who visits a hospital.

(Configuration of the learning support device)
2 is a configuration diagram showing an example of the learning support device 1. The learning support device 1 includes a control unit 40, a real time clock (RTC) module 41, a global positioning system (GPS) module 42, a motion sensor unit 43, a speaker 44, and a communication processing unit 45.

The RTC module 41 has calendar and clock functions. The RTC module 41 outputs date information and time information for generating a safety behavior judgment history to the control unit 40 in response to a request from the control unit 40.

The GPS module 42 detects the current position of the learning support device 1, i.e., the learner's current position Po, using radio waves received from GPS satellites. The GPS module 42 outputs the position information of the detected current position to the control unit 40 in response to a request from the control unit 40. The GPS module 42 is a position detection means that detects the learner's position.

The motion sensor unit 43 includes one or more sensors and detects the learner's movements. The motion sensor unit 43 includes, for example, an acceleration sensor and an angular velocity sensor. The motion sensor unit 43 outputs the detection values of each sensor, such as acceleration and angular velocity, to the control unit 40 in response to a request from the control unit 40. The motion sensor unit 43 is a movement detection means that detects the learner's movements.

The speaker 44 outputs an alarm sound such as a buzzer or voice (message such as "You are in an area where safety behavior is required") in response to an alarm signal input from the control unit 40. The control unit 40 outputs an alarm signal to the speaker 44 when the learner's current position Po is within an area (hereinafter referred to as the "designated area") with a radius of distance D centered on designated positions P#1 to #3. Therefore, when the learner reaches the designated area, he or she can recognize that safety behavior is required by hearing the alarm sound from the speaker 44.

The communication processing unit 45 is, for example, a wireless communication circuit conforming to LTE, and processes communication between the control unit 40 and the recording server 3 and 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 outputs data signals input from the network 9 to the control unit 40.

When the current position Po is within the designated area, the control unit 40 outputs an alarm signal to the speaker 44 and determines whether the learner has performed safe behavior for each of the designated positions P#1 to P#3. Here, the control unit 40 acquires the learner's current position Po from the GPS module 42 and determines whether the current position Po is within the designated area. The control unit 40 also acquires the learner's movements from the motion sensor unit 43 and uses them to determine safe behavior.

Figure 3 is a configuration diagram showing an example of the control unit 40. The control unit 40 is, for example, a microcontroller, and has 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, the RAM 12, the storage memory 13, and the input/output port 14 via a bus 19 so that signals can be input and output between them. The control unit 40 is an example of a computer.

The ROM 11 stores a program that drives the CPU 10. The RAM 12 functions as a working memory for the CPU 10. The input/output port 14 transmits and receives various signals between, for example, the RTC module 41, the GPS module 42, the motion sensor unit 43, the speaker 44, and the communication processing unit 45. The CPU 10 inputs and outputs signals between the RTC module 41, the GPS module 42, the motion sensor unit 43, the speaker 44, and the communication processing unit 45 via the input/output port 14.

When the CPU 10 reads a program from the ROM 11, it forms the following functions: a management unit 100, a setting processing unit 101, an information acquisition unit 102, a safety behavior determination unit 103, an area notification unit 104, and a history transmission unit 105. In addition, a safety behavior management table (TBL) 130 and a determination result history table (TBL) 131 are stored in the storage memory 13. Examples of the storage memory 13 include, but are not limited to, a flash memory.

The management unit 100 manages the overall operation of the learning support device 1. The management unit 100 instructs the setting processing unit 101, the information acquisition unit 102, the safety behavior determination unit 103, the area notification unit 104, and the history transmission unit 105 to operate in accordance with a sequence set in a program.

The setting processing unit 101 receives setting information for the designated positions P#1 to #3 from the smartphone 2 via the input/output port 14. The setting information may include not only the designated positions P#1 to #3, but also the type of safety behavior for each of the designated positions P#1 to #3 (such as checking left and right). The setting processing unit 101 sets the safety behavior management table 130 according to the setting information.

Figure 4 is a diagram showing an example of the safety behavior management table 130. In the safety behavior management table 130, designated positions P#1 to #3 and necessary safety behaviors, that is, checking left and right and checking to the right as safety behaviors that the learner should take at the designated positions P#1 to #3, are registered in correspondence with each other. Here, the designated positions P#1 to #3 are longitude and latitude values based on GPS. The safety behavior management table 130 is referenced when the learner's current position Po reaches the designated area, and is used to determine the safe behavior.

Referring again to FIG. 3, the information acquisition unit 102 acquires various pieces of information from the RTC module 41, the GPS module 42, and the motion sensor unit 43 via the input/output port 14. The information acquisition unit 102 acquires date information and time information from the RTC module 41. The information acquisition unit 102 also acquires latitude and longitude information from the GPS module 42 as location information indicating the learner's current location Po, and acquires various detection values related to the learner's movements from the motion sensor unit 43.

The safety behavior judgment unit 103 is an example of a judgment unit, and when the learner's current position Po reaches an area near the designated positions P#1 to P#3, it judges whether the learner has performed a safe behavior within the designated area based on the detection result of the motion sensor unit 43. For example, the safety behavior judgment unit 103 judges that the learner has checked left and right when the detection value of the angular velocity sensor continuously fluctuates in the positive and negative directions beyond a predetermined value. In addition, the safety behavior judgment unit 103 judges that the learner is stopped when the detection value of the acceleration sensor is equal to or less than a predetermined value.

The judgment method of the safe behavior judgment unit 103 is not limited to the above, and an appropriate method is adopted depending on the type of sensors of the motion sensor unit 43 and the installation position of the learning support device 1. For example, a small camera may be provided as the motion sensor unit 43, in which case the motion sensor unit 43 judges safe behavior based on images captured by the small camera. Also, the GPS module 42 may be used together with the motion sensor unit 43 as a movement detection means to judge safe behavior, in which case the safe behavior judgment unit 103 can judge that the learner is stopped from the displacement of the current position Po detected by the GPS module 42 according to the time.

The safety behavior determination unit 103 records the safety behavior determination results for each of the specified positions P#1 to P#3 in the determination result history table 131. The safety behavior determination unit 103 obtains date information and time information from the RTC module 41 via the input/output port 14 and records them as date and time in the determination result history table 131.

Figure 5 is a diagram showing an example of the judgment result history table 131. The judgment result history table 131 records the date and time, the designated location, the safe action, and the judgment result. The date and time are obtained from the RTC module as described above. The designated location and the safe action are obtained from the safety action management table 130.

The judgment result indicates "OK" if it is determined that the learner has performed safe behavior within the designated area corresponding to the designated positions P#1-#3, and indicates "NG" if it is determined that the learner has not performed safe behavior within the designated area corresponding to the designated positions P#1-#3.

The history transmission unit 105, for example, periodically reads out the judgment result history table 131 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 transmits the judgment result history table 131 to the recording server 3 as history information.

The area notification unit 104 is an example of a notification unit, and notifies the learner that he or she is in a designated area by outputting a notification signal to the speaker 44. Therefore, when the learner reaches the designated area, he or she can recognize that safety measures are required by hearing the notification sound from the speaker 44.

The area notification unit 104 starts to notify, for example, when the learner's current position Po reaches within the designated area. At this time, the area notification unit 104 determines that the learner's current position Po has reached within the designated area based on information from the GPS module 42. This allows the learner to know that he or she has entered an area where safety behavior is required.

The management unit 100 obtains the judgment result of the safe behavior from the safety behavior judgment unit 103 and notifies the area notification unit 104. When the safety behavior judgment unit 103 judges that the learner has performed a safe behavior, the area notification unit 104 restricts the notification. For example, the area notification unit 104 stops the notification by stopping the output of the notification signal. This prevents the learner from feeling annoyed by the notification after ensuring safety through safe behavior. Note that the means for restricting the notification is not limited to this, and the area notification unit 104 may output the notification signal to reduce the volume or frequency of the notification, for example.

However, for example, if a learner stops at an intersection because the traffic light turns red after looking left and right, the alarm will stop, so there is a risk that the learner will become less careful about their safety even though the traffic conditions at the intersection have changed.

For this reason, if the learner remains in the designated area for a predetermined monitoring period after the notification restriction, the area notification unit 104 lifts the notification restriction. For example, the area notification unit 104 measures the elapsed time after the notification was stopped using a counter, and resumes the notification when the counter value reaches a predetermined value.

Therefore, if the learner remains in the designated area during the monitoring period after performing a safe behavior, the alert will resume to remind the learner that another safe behavior is required. For example, if the learner stops at an intersection because the traffic light turns red after checking both sides, the alert will resume a few minutes after the alert has stopped, and the learner will be prompted to check both sides again when the light turns green. This allows the learner to ensure safety by performing safe behavior even if traffic conditions at the intersection change after a specified period of time has passed.

In this way, the learning support device 1 can improve the effectiveness of learning safety behavior. Note that, when the area notification unit 104 restricts notifications by lowering the volume and frequency of notifications as described above, the area notification unit 104 may release the restriction by restoring the volume and frequency to their original values.

In addition, if the safety behavior determination unit 103 determines that the learner remains in the designated area during the monitoring period after the notification restriction and that the learner has not performed safe behavior, the area notification unit 104 releases the notification restriction. At this time, if the learner performs safe behavior, the area notification unit 104 resets the counter value that measures the monitoring period so that it does not reach a predetermined value.

Therefore, if the learner voluntarily performs a safe behavior again before the monitoring period has elapsed, the notification is not lifted, and the learner is less likely to feel annoyed. However, the area notification unit 104 may also lift the notification restriction to increase the learner's awareness of safety even if the learner remains within the designated area during the monitoring period and the safety behavior determination unit 103 determines that the learner has performed a safe behavior.

In this way, after the learner has performed a safe behavior, if the traffic light is red, the learner will stop in front of the crosswalk, but the notification will resume after the monitoring period has elapsed. On the other hand, if the traffic light is green, the learner will cross the crosswalk without stopping. In this case, if the notification were to resume when the monitoring period has elapsed while the learner is crossing, the learner may feel annoyed.

The area notification unit 104 therefore lifts the notification restriction if the learner remains in the designated area during the monitoring period after the notification restriction. At this time, if the area notification unit 104 detects the movement of the learner from the detection results of the motion sensor unit 43, for example, it resets the counter value that times the monitoring period so that it does not reach a predetermined value.

As a result, the area notification unit 104 does not lift the notification restriction while the learner is moving, so notifications do not resume even when the learner is crossing a crosswalk, preventing the learner from feeling annoyed. However, the area notification unit 104 may also lift the notification restriction when the monitoring period has elapsed, even if the learner is moving within a designated area, in order to further alert the learner.

In addition, if the learner remains in the designated area during the monitoring period after the notification restriction, the area notification unit 104 lifts the notification restriction in response to the learner starting to move. At this time, the area notification unit 104 lifts the notification restriction when, for example, the movement of the learner is detected from the detection result of the motion sensor unit 43 after the counter value reaches a predetermined value.

For this reason, the learner receives a notification when he or she starts to cross the crosswalk at a green light after the monitoring period has elapsed since stopping at a red light. Therefore, the learner is alerted to safety in a timely manner when he or she starts to move, and is urged to take safe action again. Note that, differently from this, the area notification unit 104 may lift the notification restriction immediately after the monitoring period has elapsed in order to prompt the learner to take safe action early on.

In addition, if the learner goes outside the designated area after the area notification unit 104 has released the notification restriction, the area notification unit 104 will restrict notification. This allows the learner to know that he or she has gone outside the designated area where safety behavior is not required.

(Operation of the control unit)
Next, the operation of the control unit 40 will be described. In the control unit 40, the management unit 100 instructs the setting processing unit 101 to set the safe behavior management table 130, and then instructs the information acquisition unit 102 to acquire various information from the RTC module 41, the GPS module 42, and the motion sensor unit 43, and instructs the safe behavior determination unit 103 and the area notification unit 104 to perform safe behavior determination and notification, respectively.

Figure 6 is a flowchart showing an example of information acquisition processing. This processing is executed repeatedly at a predetermined interval, for example.

The information acquisition unit 102 acquires date information and time information from the RTC module 41 (step St1). Next, the information acquisition unit 102 acquires the learner's current position Po from the GPS module 42 (step St2). The current position Po is indicated by, for example, latitude and longitude.

Next, the information acquisition unit 102 acquires various detection values related to the learner's movements from the motion sensor unit 43 (step St3). The detection values include, but are not limited to, acceleration and angular acceleration, and are appropriately determined depending on the installation position of the learning support device 1 and the type of safe behavior to be judged. The management unit 100 outputs the various information acquired by the information acquisition unit 102 to the safe behavior judgment unit 103 and the area notification unit 104 as necessary.

Figure 7 is a flowchart showing an example of a process for instructing the determination of safe behavior. This process is started, for example, when a child who is a learner starts going to or from school, and stops when the child finishes going to or from school.

The management unit 100 reads the safety behavior management table 130 from the storage memory 13 (step St11). The safety behavior management table 130 is set in advance from the parent's smartphone 2.

Next, the management unit 100 selects one of the designated positions P#1 to P#3 from the safety behavior management table 130 (step St12). Next, the management unit 100 instructs the safety behavior determination unit 103 and the area notification unit 104 to perform a safe behavior determination process and a notification process for the selected designated position P#1 to P#3 (step St13).

The management unit 100 then determines whether or not all of the designated positions P#1-#3 in the safety behavior management table 130 have been selected (step St14). If there are any unselected designated positions P#1-#3 (No in step St14), the management unit 100 selects the next designated position P#1-#3 (step St12). Then, the processes of steps St13 and St14 are executed again. Here, the management unit 100 selects the designated positions P#1-#3 in the order along the child's route to and from school, for example.

Also, if all of the specified positions P#1 to P#3 have been selected (Yes in step St14), the management unit 100 ends the process.

Figures 8 and 9 are flowcharts showing an example of a safe behavior determination process and a notification process. Each of the flowcharts in Figures 8 and 9 shows a series of processes by linking the symbols A and B in Figure 8 with the symbols A and B in Figure 9.

The area notification unit 104 calculates the distance D between the current position Po and the selected designated position P#1-#3 (step St21). Next, the area notification unit 104 compares the distance D with the threshold Dth (step St22). This allows the area notification unit 104 to determine whether the learner's current position Po has reached the designated area. Note that the threshold Dth is, for example, an individual value for each designated position P#1-#3, and is determined according to various conditions of the designated positions P#1-#3, such as the size of the intersection.

If the distance D is greater than the threshold Dth (No in step St22), the area notification unit 104 executes the process of step St21 again. If the distance D is equal to or less than the threshold Dth (Yes in step St22), the area notification unit 104 starts the notification (step St23). This lets the learner know that he or she has reached a designated area where safety behavior is required, and alerts the learner to pay attention to safety.

Next, the safety behavior determination unit 103 analyzes the learner's behavior based on each detection value of the motion sensor unit 43 (step St24). Next, the safety behavior determination unit 103 determines from the results of the behavior analysis whether the learner performed a safe behavior corresponding to the selected designated position P#1 to #3 (step St25). For example, the safety behavior determination unit 103 determines from the acceleration and angular acceleration whether the learner checked left and right within the designated area of the designated position P#1.

If the safety behavior judgment unit 103 judges that the learner is not performing a safe behavior (No in step St25), the safety behavior judgment unit 103 calculates the distance D between the current position Po and the selected designated position P#1 to #3 (step St27). Next, the safety behavior judgment unit 103 compares the distance D with the threshold value Dth (step St28). In this way, the safety behavior judgment unit 103 judges whether the learner's current position Po remains within the designated area.

If the distance D is equal to or less than the threshold value Dth (Yes in step St28), the processes from step St24 onwards are executed again. On the other hand, if the distance D is greater than the threshold value Dth (No in step St28), the area notification unit 104 determines that the learner has left the designated area, stops the notification (step St29), and ends the process. At this time, the safety behavior determination unit 103 records the result of the safety behavior determination in the determination result history table 131.

Furthermore, if the safety behavior determination unit 103 determines that the learner has performed a safe behavior (Yes in step St25), the area notification unit 104 stops the notification (step St26). This prevents the learner from feeling annoyed by the continuation of notifications after the learner has performed a safe behavior. Note that, although the present example uses the stopping of notifications as an example of limiting notifications, this is not limiting, and as described above, the area notification unit 104 may limit notifications to reduce their volume or frequency.

Next, the area notification unit 104 starts counting to time the monitoring period (step St30). In this way, the area notification unit 104 times the elapsed time after the notification was stopped.

Next, the area notification unit 104 calculates the distance D between the current position Po and the selected designated position P#1 to #3 (step St31). Next, the area notification unit 104 compares the distance D with a threshold value Dth (step St32). This allows the area notification unit 104 to determine whether the learner's current position Po remains within the designated area.

If the distance D is greater than the threshold Dth (No in step St32), the area notification unit 104 determines that the learner has left the designated area, stops counting (step St36), and ends this process. For example, if a child of the learner checks both sides before the crosswalk when the traffic light at the intersection is green (at this time, the notification stops), and finishes crossing the crosswalk and leaves the intersection before the traffic light turns red, the notification is not resumed in step St24 described below, and this process ends. At this time, the safe behavior determination unit 103 records the safe behavior determination result in the determination result history table 131.

If the distance D is equal to or less than the threshold value Dth (Yes in step St32), the safety behavior determination unit 103 determines that the learner remains within the designated area and analyzes the learner's behavior based on the detection values of the motion sensor unit 43 (step St33). Next, the safety behavior determination unit 103 determines from the results of the behavior analysis whether the learner performed a safe behavior corresponding to the selected designated position P#1 to #3 (step St34).

If the safety behavior determination unit 103 determines that the learner has performed a safe behavior (Yes in step St34), the area notification unit 104 resets the counter value for timing the monitoring period to 0 (step St35). Therefore, as long as the learner voluntarily performs a safe behavior after the notification is stopped, the monitoring period will not elapse, and notification will not be resumed in step St40, which will be described later.

In addition, if the safety behavior determination unit 103 determines that the learner is not performing safe behavior (No in step St34), the area notification unit 104 determines whether the learner is stopped or not based on each detection value of the motion sensor unit 43 (step St37). At this time, for example, the area notification unit 104 may determine that the learner is stopped if the detection value of the acceleration sensor is less than a threshold value. This allows the area notification unit 104 to determine whether, for example, a child learner is standing still following a red light or is moving.

If it is determined that the learner is stopped (Yes in step St37), the processes from step St31 onwards are performed again. In this case, the counter value is incremented without being reset.

If it is determined that the learner is moving (No in step St37), the area notification unit 104 compares the counter value with a predetermined value T (step St38). If the counter value is less than the predetermined value T (No in step St38), the area notification unit 104 resets the counter value to 0 (step St41). After that, the processes from step St31 onwards are performed again.

If the counter value is equal to or greater than the predetermined value T (Yes in step St38), the area notification unit 104 stops the counter (step St39) and resumes notification (step St40). After that, the processes in and after step St24 are performed.

In this way, if the learner remains in the designated area during the monitoring period after the notification has stopped, the area notification unit 104 resumes notification when the learner starts moving. Therefore, for example, a child learner will receive a notification when he or she starts crossing the pedestrian crossing at a green light after the monitoring period has elapsed since stopping at a red light, and will be prompted to check left and right again in a timely manner.

Furthermore, the area notification unit 104 resumes notification if the learner remains in the designated area during the monitoring period after the notification has stopped through the processing of steps St37 to St41 described above. For example, after a child of the learner stops in front of a pedestrian crossing following a red light and looks to the left and right (notification stops at this time), notification resumes when the monitoring period has elapsed, prompting the learner to look to the left and right again. Furthermore, if a child stops in front of a pedestrian crossing, looks to the left and right, and then begins to cross the street following a green light, notification does not resume even after the monitoring period has elapsed, reducing the learner's feeling of annoyance while crossing.

Furthermore, if the safety behavior determination unit 103 determines that the learner remains in the designated area during the monitoring period after limiting notification through the processes of steps St31 to St41 above and that the learner is not behaving safely, the area notification unit 104 resumes notification. For example, if a child of the learner is following a red light and stops in front of a pedestrian crossing at an intersection, repeatedly looking left and right, notification will not resume. Therefore, by checking left and right again, the child is less likely to feel annoyed by the resumption of notification, and can develop the habit of repeatedly looking left and right after a period of time.

In addition, the area notification unit 104 restricts notifications if the learner leaves the designated area after removing the notification restriction through the processing of steps St27 to St29 described above. This allows the learner to know that he or she has left the designated area where safety behavior is not required.

As described above, the learning support device 1 of this example can effectively support learners such as children in learning safety behaviors that ensure traffic safety. However, the learning support device 1 is not limited to traffic safety, and may be a device that supports learning behaviors that ensure safety against accidents caused by the topography of the school route, for example. In this case, the designated positions P#1 to P#3 may be designated as roads near steep slopes, and the safety behavior determination unit 103 may determine whether the learner has confirmed safety within the designated area. In this way, the uses of the learning support device 1 are not limited.

The above-described embodiment is a preferred example of the present invention. However, the present invention is not limited to this embodiment, and various modifications are possible without departing from the spirit of the present invention.
