Description

[Technical field]

[0001] The present invention relates to a learning support device. [Background technology]

[0002] 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 the detection values ​​to a data center, and the data center evaluates the behavior based on the detection values. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2019 / 240070 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above system, when a child approaches an intersection, the terminal vibrates to alert the child to the surroundings and to draw the child's attention to the surroundings. The alert stops after the child takes the necessary action to ensure road safety.

[0005] However, for example, if a child stops at an intersection because the traffic light turns red after checking both sides, the terminal stops notifying the child, so there is a risk that the child will not pay attention to safety even though the traffic situation at the intersection has changed. Therefore, with the above system, it is difficult for the child to fully learn safety behavior. Note that this problem is not limited to learning traffic safety behavior, but also exists in learning other safety behaviors necessary to avoid accidents due to the topography of the school route, for example.

[0006] Therefore, the present invention has been made in consideration of the above problems, and has an object to provide a learning support device that improves the effectiveness of learning safety behavior. [Means for solving the problem]

[0007] The learning support device of the present invention is a learning support device carried by a learner who is learning safety behaviors, and has an alarm unit that notifies the learner that the learner is within a designated area, and a judgment unit that judges whether the learner has performed the behavior within the designated area, and the alarm unit restricts the alarm if the judgment unit judges that the learner has performed the behavior, and lifts the restriction on the alarm if the learner remains within the designated area for a predetermined period of time after the restriction on the alarm.

[0008] In the above configuration, the notification unit may lift the notification restriction in response to the learner starting to move if the learner remains within the designated area for the specified period after the notification restriction.

[0009] In the above configuration, the notification unit may cancel the restriction on the notification when the learner stops within the designated area for the predetermined period after the restriction on the notification.

[0010] In the above configuration, the notification unit may lift the restriction on the notification if the judgment unit determines that the learner remains within the designated area for the specified period after the restriction on the notification and that the learner has not performed the behavior.

[0011] In the above configuration, the notification unit may limit the notification when the learner moves outside the designated area after the restriction on the notification is lifted.

[0012] In the above configuration, the notification unit may stop the notification when the judgment unit judges that the learner has performed the action, and may resume the notification if the learner remains within the designated area for the specified period after the notification has been stopped.

[0013] In the above configuration, the determination unit may determine whether or not the learner has performed the behavior for ensuring traffic safety within the designated area. Effect of the Invention

[0014] According to the present invention, it is possible to improve the effectiveness of learning safety behavior. [Brief description of the drawings]

[0016] (Configuration and functions of the traffic safety learning support system) Fig. 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.

[0017] The learning support device 1 is a portable device that teaches, for example, a child 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 substantially rectangular badge-type device, and is attached to the child's hat H for school. This allows the child to easily carry the learning support device 1 when going to and from school.

[0018] The attachment position of the learning support device 1 is not limited to this, and may be attached to, for example, the shoulder strap of a child's school bag or to a child's clothing. The shape of the learning support device 1 is also not limited, and may be, for example, a wristwatch type shape so that it can be attached to a child's arm.

[0019] The learning support device 1 judges whether or not a child has engaged in safe behavior at multiple designated positions, for example, on a route to school. The designated positions are places where caution is required for traffic safety, such as intersections and corners. The learning support device 1 records a history of judgments on whether or not a child has engaged in safe behavior at each designated position, and transmits the history information to the recording server 3, for example, periodically.

[0020] The recording server 3 saves the judgment history of the safety behavior recorded by the learning support device 1 in a history database (DB) 30. The history database 30 is stored in the hard disk drive or solid state drive of the recording server 3.

[0021] 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 transmitted from the smartphone 2 to the learning support device 1.

[0022] Furthermore, the smartphone 2 acquires history information on safe behavior from the recording server 3 based on the function of the application 20. The application 20 displays on the touch panel of the smartphone 2 the judgment result of the child's safe behavior together with the child's movement route on a map.

[0023] Reference symbol Gb indicates an example of a touch panel screen displayed by the application 20. On the screen, 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 behavior, and judgment results 81 to 83 at each of the designated positions P#1 to #3 are displayed. Note that in this example, the safety behavior is, but is not limited to, checking for traffic safety.

[0024] 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."

[0025] Furthermore, the designated position P#2 corresponds to a T-junction area, and checking to the right is required as a safety precaution. If the child does not check, the judgment result 82 of the designated position P#2 will be "NG."

[0026] In addition, the designated position P#3 corresponds to 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 becomes "OK".

[0027] Therefore, the parent can check the results of the child's safety behavior through the screen of the smartphone 2. In this example, a child is given as a learner of safety behavior, but the learner is not limited to this and may be, for example, an elderly person who visits a hospital.

[0028] (Configuration of 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, 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.

[0029] The RTC module 41 has calendar and clock functions, and outputs date information and time information for generating a safety behavior determination history to the control unit 40 in response to a request from the control unit 40.

[0030] The GPS module 42 detects the current position of the learning support device 1, i.e., the current position Po of the learner, by radio waves received from a GPS satellite. The GPS module 42 outputs 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 for detecting the position of the learner.

[0031] The motion sensor unit 43 includes one or more sensors and detects the movements of the learner. 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 the 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 movements of the learner.

[0032] The speaker 44 outputs an alarm sound such as a buzzer or voice (message such as "This is 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") having a radius of distance D centered on the 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.

[0033] 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 a data signal input from the control unit 40 to the network 9, and outputs a data signal input from the network 9 to the control unit 40.

[0034] When the current position Po is within the designated area, the control unit 40 outputs a notification signal to the speaker 44 and judges whether the learner has performed a safe behavior for each of the designated positions P#1 to #3. Here, the control unit 40 acquires the current position Po of the learner from the GPS module 42 and judges whether the current position Po is within the designated area. The control unit 40 also acquires the movement of the learner from the motion sensor unit 43 and uses it to judge the safe behavior.

[0035] 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 as to be able to input and output signals to and from each other. The control unit 40 is an example of a computer.

[0036] 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 to and from, 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 to and from 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.

[0037] When the CPU 10 reads a program from the ROM 11, it functions as a management unit 100, a setting processing unit 101, an information acquisition unit 102, a safe behavior determination unit 103, an area notification unit 104, and a history transmission unit 105. The storage memory 13 stores a safe behavior management table (TBL) 130 and a determination result history table (TBL) 131. The storage memory 13 may be, but is not limited to, a flash memory.

[0038] 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.

[0039] 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 in accordance with the setting information.

[0040] 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 right direction as safety behaviors that a learner should take at the designated positions P#1 to #3, are registered in association 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 referred to when the learner's current position Po reaches a designated area, and is used to determine the safe behavior.

[0041] 3 again, the information acquiring 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 acquiring unit 102 acquires date information and time information from the RTC module 41. In addition, the information acquiring unit 102 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.

[0042] The safety behavior determination unit 103 is an example of a determination unit, and when the learner's current position Po reaches an area near the designated positions P#1 to P#3, it determines 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, when the detection value of the angular velocity sensor continuously varies in the positive and negative directions beyond a predetermined value, the safety behavior determination unit 103 determines that the learner has performed a left / right check. Also, when the detection value of the acceleration sensor is equal to or less than a predetermined value, the safety behavior determination unit 103 determines that the learner is stopped.

[0043] 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 the safe behavior based on an image captured by the small camera. Also, the GPS module 42 may be used as a movement detection means together with the motion sensor unit 43 to judge the safe behavior, in which case the safe behavior judgment unit 103 can judge that the learner is stopped based on the displacement of the current position Po detected by the GPS module 42 according to the time.

[0044] The safe action determination unit 103 records the judgment result of the safe action for each of the designated positions P#1 to P#3 in the judgment result history table 131. The safe action determination unit 103 obtains date information and time information from the RTC module 41 via the input / output port 14, and records it in the judgment result history table 131 as date and time.

[0045] 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 behavior, and the judgment result. The date and time are obtained from the RTC module as described above. The designated location and the safe behavior are obtained from the safety behavior management table 130.

[0046] 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 to #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 to #3.

[0047] The history transmission unit 105 reads out the judgment result history table 131 from the storage memory 13, for example, periodically, 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.

[0048] The area notification unit 104 is an example of a notification unit, and notifies the learner that he / she is in the designated area by outputting a notification signal to the speaker 44. Therefore, when the learner reaches the designated area, he / she can recognize that safety behavior is required by hearing the notification sound from the speaker 44.

[0049] The area notification unit 104 starts the notification, for example, when the current position Po of the learner reaches within the designated area. At this time, the area notification unit 104 determines that the current position Po of the learner has reached within the designated area based on the information of the GPS module 42. This allows the learner to know that he or she has entered an area where safety behavior is required.

[0050] The management unit 100 acquires 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 the 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 so as to reduce the volume or frequency of the notification, for example.

[0051] 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, which may cause the learner to become less careful about their safety even though the traffic conditions at the intersection are changing.

[0052] 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 releases 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.

[0053] Therefore, if the learner remains in the designated area during the monitoring period after performing the safe behavior, the warning will be resumed to remind the learner that the safe behavior is necessary again. For example, if the learner stops at an intersection because the traffic light turns red after checking both sides, the warning will be resumed several minutes after the warning has stopped, and the learner will be prompted to check both sides again when the traffic light turns green. This allows the learner to ensure safety by performing the safe behavior even if the traffic conditions at the intersection change after a certain period of time has passed.

[0054] In this way, the learning support device 1 can improve the learning effect of safe behavior. When the area notification unit 104 restricts notification by lowering the volume and frequency of notification as described above, the area notification unit 104 may release the restriction by restoring the volume and frequency to their original values.

[0055] Furthermore, 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.

[0056] Therefore, if the learner voluntarily performs a safe behavior again before the monitoring period has elapsed, the notification is not cancelled, and the learner is prevented from feeling annoyed. However, the area notification unit 104 may also cancel the notification restriction to increase the learner's awareness of safety even if the learner remains in the designated area during the monitoring period and the safety behavior determination unit 103 determines that the learner has performed a safe behavior.

[0057] In this way, after the learner performs a safe behavior, if the traffic light is red, the learner stops in front of the crosswalk, but the notification resumes after the monitoring period has elapsed. On the other hand, if the traffic light is green, the learner crosses the crosswalk without stopping. In this case, if the notification resumes when the monitoring period has elapsed while the learner is crossing, the learner may feel annoyed.

[0058] Therefore, if the learner stops within the designated area during the monitoring period after the notification restriction, the area notification unit 104 releases the notification restriction. At this time, if the area notification unit 104 detects the movement of the learner from the detection result of the motion sensor unit 43, for example, it resets the counter value for timing the monitoring period so that it does not reach a predetermined value.

[0059] Therefore, the area notification unit 104 does not release the notification restriction while the learner is moving, so notification is not resumed even when the learner is crossing a pedestrian crossing, and the learner is prevented from feeling annoyed. However, unlike this, the area notification unit 104 may release the notification restriction when the monitoring period has elapsed, in order to further alert the learner, even if the learner is moving within a designated area.

[0060] Furthermore, if the learner remains in the designated area during the monitoring period after the notification restriction, the area notification unit 104 releases the notification restriction in response to the learner starting to move. At this time, the area notification unit 104 releases 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.

[0061] Therefore, the learner receives a notification when he / she starts to cross the crosswalk at a green light after the monitoring period has elapsed since he / she stopped at the red light. Therefore, the learner is alerted to safety at the appropriate time when he / she starts to move, and is urged to take safe action again. However, the area notification unit 104 may, differently from this, release the restriction on notifications immediately after the monitoring period has elapsed in order to prompt the learner to take safe action early.

[0062] Furthermore, if the learner goes outside the designated area after the area notification unit 104 has released the notification restriction, the area notification unit 104 restricts the notification, so that the learner can know that he or she has gone outside the designated area where safety behavior is not required.

[0063] (Operation of 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.

[0064] 6 is a flowchart showing an example of information acquisition processing. This processing is executed repeatedly at a predetermined interval, for example.

[0065] The information acquiring unit 102 acquires date information and time information from the RTC module 41 (step St1). Next, the information acquiring unit 102 acquires the current position Po of the learner from the GPS module 42 (step St2). The current position Po is indicated by, for example, latitude and longitude.

[0066] 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.

[0067] 7 is a flowchart showing an example of a process for instructing a safe behavior judgment. This process is started, for example, when a child, who is a learner, starts going to or from school, and stops when the child ends.

[0068] The management unit 100 reads out the safe behavior management table 130 from the storage memory 13 (step St11). The safe behavior management table 130 is set in advance from the parent's smartphone 2.

[0069] Next, the management unit 100 selects one of the designated positions P#1 to #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 #3, respectively (step St13).

[0070] Next, the management unit 100 judges whether or not all the designated positions P#1-#3 in the safety behavior management table 130 have been selected (step St14). If there are unselected designated positions P#1-#3 (No in step St14), the management unit 100 selects the next designated position P#1-#3 (step St12). After that, the processes of steps St13 and St14 are executed again. Here, the management unit 100 selects the designated positions P#1-#3 according to the order along the child's route to and from school, for example.

[0071] Moreover, if all of the designated positions P#1 to P#3 have been selected (Yes in step St14), the management unit 100 ends the process.

[0072] Fig. 8 and Fig. 9 are flowcharts showing an example of a safe behavior determination process and a notification process. Each of the flowcharts in Fig. 8 and Fig. 9 shows a series of processes by linking the symbols A and B in Fig. 8 with the symbols A and B in Fig. 9.

[0073] 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 a 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 of the designated positions P#1-#3, and is determined according to various conditions of the designated positions P#1-#3, such as the size of the intersection.

[0074] 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 notification (step St23). This allows the learner to know that he or she has arrived in a designated area where safety behavior is required, and alerts the learner to pay attention to safety.

[0075] Next, the safety behavior determination unit 103 analyzes the behavior of the learner based on each detection value of the motion sensor unit 43 (step St24). Next, the safety behavior determination unit 103 determines whether or not the learner performed a safe behavior according to the selected designated position P#1 to #3 based on the result of the behavior analysis (step St25). For example, the safety behavior determination unit 103 determines whether or not the learner performed a left / right check within the designated area of ​​the designated position P#1 based on the acceleration and angular acceleration.

[0076] If the safety behavior judgment unit 103 judges that the learner has not performed 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 a threshold value Dth (step St28). In this way, the safety behavior judgment unit 103 judges whether the current position Po of the learner remains within the designated area.

[0077] If the distance D is equal to or smaller than the threshold Dth (Yes in step St28), the processes from step St24 onward are executed again. If the distance D is greater than the threshold Dth (No in step St28), the area notification unit 104 determines that the learner has gone outside 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 safe behavior determination in the determination result history table 131.

[0078] Furthermore, when 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 safe behavior. Note that, in this example, the notification restriction is exemplified by the suspension of notifications, but is not limited thereto, and as described above, the area notification unit 104 may restrict the notification so as to reduce the volume or frequency.

[0079] Next, the area notification unit 104 starts counting to measure the monitoring period (step St30). In this manner, the area notification unit 104 measures the elapsed time after the notification has stopped.

[0080] Next, the area notification unit 104 calculates the distance D between the current position Po and the selected designated position P#1-#3 (step St31). Next, the area notification unit 104 compares the distance D with a threshold value Dth (step St32). In this way, the area notification unit 104 determines whether the current position Po of the learner remains within the designated area.

[0081] If the distance D is greater than the threshold Dth (No in step St32), the area notification unit 104 determines that the learner has gone outside the designated area, stops counting (step St36), and ends this process. For example, if a child of the learner checks left and right before the pedestrian crossing when the traffic light at the intersection is green (at this time, the notification stops), and finishes crossing the pedestrian crossing and leaves the intersection before the traffic light turns red, the notification is not resumed in step St24 described later, and this process ends. At this time, the safe behavior determination unit 103 records the determination result of the safe behavior in the determination result history table 131.

[0082] On the other hand, if the distance D is equal to or smaller 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 behavior of the learner based on each detection value of the motion sensor unit 43 (step St33). Next, the safety behavior determination unit 103 determines, based on the result of the behavior analysis, whether or not the learner has performed a safe behavior in accordance with the selected designated position P#1 to #3 (step St34).

[0083] When 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 does not elapse, and notification is not resumed in step St40 described later.

[0084] Furthermore, if the safety behavior determination unit 103 determines that the learner is not performing a 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 of the learner is standing still following a red light or is moving.

[0085] When it is determined that the learner is stopped (Yes in step St37), the processes from step St31 onward are performed again. In this case, the counter value is incremented without being reset.

[0086] Furthermore, 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.

[0087] 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.

[0088] In this way, if the learner remains in the designated area during the monitoring period after the notification is stopped, the area notification unit 104 resumes notification when the learner starts moving. Therefore, for example, a child of the learner receives 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 is prompted to check left and right again in a timely manner.

[0089] Furthermore, the area notification unit 104 resumes notification if the learner remains in the designated area during the monitoring period after the notification has been stopped through the processes of steps St37 to St41 described above. For example, if a child of the learner follows a red light and stops in front of a pedestrian crossing to check both sides (notification is stopped at this time), notification resumes when the monitoring period has elapsed, urging the learner to check both sides again. Also, if a child stops in front of a pedestrian crossing to check both sides and then starts crossing the road following a green light, notification does not resume even after the monitoring period has elapsed, preventing the learner from feeling annoyed while crossing.

[0090] Furthermore, when the safety behavior determination unit 103 determines that the learner remains in the designated area during the monitoring period after the notification restriction by each process of steps St31 to St41 and that the learner is not performing safe behavior, the area notification unit 104 resumes notification. For example, if a child of the learner repeatedly checks left and right while following a red light and stopping in front of a pedestrian crossing at an intersection, notification will not be resumed. Therefore, the child can acquire the habit of repeatedly checking left and right at intervals, since the child is prevented from feeling annoyed by the resumption of notification by checking left and right again.

[0091] Furthermore, the area notification unit 104 limits notification when the learner goes outside the designated area after the notification restriction is released by the processes of steps St27 to St29 described above. This allows the learner to know that he or she has gone outside the designated area where safety behavior is not required.

[0092] As described above, the learning support device 1 of this example can effectively support a learner such as a child in learning safety behavior to ensure traffic safety. However, the learning support device 1 is not limited to traffic safety, and may be a device that supports learning behavior to ensure safety against accidents caused by the topography of a school route, for example. In this case, a road near a steep slope may be specified as the specified positions P#1 to P#3, and the safety behavior determination unit 103 may determine whether or not the learner has confirmed safety within the specified area. In this way, the use of the learning support device 1 is not limited.

[0093] The above-described embodiment is a preferred example of the present invention, but the present invention is not limited to this embodiment and can be modified in various ways without departing from the scope of the present invention. [Explanation of symbols]
