Hereinafter, embodiments of the electronic device of the present invention will be described with reference to the accompanying drawings.
The electronic device according to the present embodiment is used, for example, as a mobile terminal (first mobile terminal 2) constituting the information communication system 1 described later. Electronic devices are installed, for example, on the body, clothing or personal belongings of a carrier (such as a moving pedestrian).

FIG. 1 is a perspective view of the electronic device 100 according to the embodiment as viewed from the front side. FIG. 2 is an exploded perspective view of the electronic device 100 according to the embodiment as viewed from the front side, showing a state in which the cover 101 and the base 109 are removed. 3, FIG. 4 and FIG. 5 are perspective views of the cover 101, the inner lid 103, and the case 105 of the electronic device 100 according to the embodiment, sequentially viewed from the front side, the rear side, and the lower side.
As shown in FIGS. 1 to 5, the electronic device 100 includes, for example, a cover 101, an inner lid 103, a case 105, a frame 107, and a base 109. In the electronic device 100, the structure 100a including the cover 101, the inner lid 103, and the case 105 constitutes a housing in which a space for accommodating the frame 107 and electronic components is formed inside.

In the following, the X-axis, Y-axis, and Z-axis directions that are orthogonal to each other in the three-dimensional space are parallel to each axis. As shown in FIG. 1, the X-axis direction is parallel to the front-rear direction of the electronic device 100, and the positive direction in the X-axis direction is parallel to, for example, the direction from the rear RE to the front FR of the structure 100a. The Y-axis direction is parallel to the left-right direction of the electronic device 100, and the positive direction in the Y-axis direction is, for example, parallel to the direction from the left side LS to the right side RS of the structure 100a. The Z-axis direction is parallel to the vertical direction of the electronic device 100, and the positive direction in the Z-axis direction is, for example, parallel to the direction from the lower LP to the upper UP of the structure 100a.
Further, in the following, when the electronic device 100 is installed in the mobile phone, the front-back direction, the left-right direction, and the up-down direction of the electronic device 100 are the same as the front-back direction, the left-right direction, and the up-down direction of the carrier.
Further, in the structure 100a, the surface of the upper UP is the upper surface UPS, the surface of the lower LP is the lower surface LPS, the surface of the left side LS is the left side LSS, and the surface of the right side RS is the right side RSS. The surface of the rear RE is the rear side surface RES, and the surface of the front FR is the front side surface FRS.

As shown in FIG. 1, the outer shape of the structure 100a is formed so that the vertical length LF at the front end of the front FR is shorter than the vertical length LR at the rear end of the rear RE. .. Further, the outer shape of the structure 100a is formed so that the maximum length L1 in the front-rear direction is longer than the maximum length L2 in the vertical direction. Further, in the outer shape of the structure 100a, the height position of the highest portion HF in the vertical direction (vertical direction) at the front end of the front FR is the height of the highest portion HR in the vertical direction (vertical direction) at the rear end of the rear RE. It is formed so as to be lower than the position.

The outer shape of the cover 101 is formed so as to bulge in the positive direction in the Z-axis direction (that is, above the vertical direction of the electronic device 100), for example. For example, the outer shape of the cover 101 is directed from the rear 101a (or the rear RE) to the front 101b (or the front FR) in the positive direction in the X-axis direction (that is, the front direction in the front-rear direction of the electronic device 100). It is formed in a shape in which the distance between the reference position and the tip position in the positive direction in the Z-axis direction changes in a decreasing tendency. The reference position is, for example, the lowermost position of the lower end edge portion 112, which will be described later. The tip position is, for example, a position on the surface (outer surface) 101A described later.
That is, the outer shape of the cover 101 is formed into a shape in which the tip position in the positive direction in the Z-axis direction changes in a downward trend as the rear portion 101a moves toward the front portion 101b in the positive direction in the X-axis direction, that is, a so-called front-down shape.

Notify. Geolocation information is information indicating a geographical location. The geographical position is a position on the route through which the carrier of the first mobile terminal 2 passes, for example, a position where a child may be in danger. Geographical locations include, for example, intersections on routes, locations on sidewalks separated from roadways, and the vicinity of dangerous structures. The geographical location includes points (eg, safety confirmation points, etc.) that require the execution of predetermined actions such as a stop motion, a left / right confirmation motion, and a hand raising motion.
In the following description, the case where the geographical position information includes the geographical position on the walking route when the child goes to and from school will be described.

The first mobile terminal 2 identifies the position of the first mobile terminal 2 (that is, the position of a child) based on a positioning signal received from a satellite or the like by the position detection unit 24, and position information indicating the specified position. To the data center 4B.

The information communication system 1B may adopt a method other than the position detection unit 24 as long as it is a method that can specify the position of the child. For example, the first mobile terminal 2 is the first mobile terminal 2 by a method such as BLE (Bluetooth (registered trademark) Low Energy), PDR (Pedestrian Dead Reckoning), IEMS (IndoorMEssaging System), SLAM (Simultaneous Localization and Mapping). The position of may be specified. The first mobile terminal 2 may specify the position of the first mobile terminal 2 based on the peripheral information detected by the radar 22.

The geographical position PT1 is preset at the position of the intersection. The geographical position PT1 is preferably set on the path rt on which the child C1 walks, rather than on the center of the intersection. For example, in a road where a road and a sidewalk are separated, the route rt is a sidewalk, and the geographical position PT1 is set on the sidewalk (more specifically, the boundary between the sidewalk and the road).

The notification unit 421 operates the vibrator 25 when the child C1 approaches a position (that is, a predetermined range ARP shown) separated by a predetermined distance (first predetermined distance dt1 shown) from the geographical position PT1. The first predetermined distance dt1 is, for example, a distance of about several meters. Further, the notification unit 421 may change the notification intensity (for example, the vibration intensity) according to the distance to the geographical position PT1. The child C1 walks while paying attention to the surroundings by being notified of the geographical position PT1 (that is, the intersection) by the vibrator 25. Therefore, the information communication system 1B can prevent the child C1 from coming into contact with the vehicle m traveling in the traveling direction of the child C1.

In the above description, the case where the distance from the position of the child C1 to the geographical position PT1 is a linear distance has been described, but the present invention is not limited to this. The distance from the position of the child C1 to the geographical position PT1 may be the distance along the path rt of the child C1. The notification unit 421 suppresses long-term notification by performing notification based on the distance to the geographical position PT1 along the path rt of the child C1, so that the child C1 becomes accustomed to the notification state. It can be suppressed.
As described above, the information communication system 1B of the second modification of the embodiment can more appropriately notify the child C1 of the approach of the geographical position.

<Third variant of the information communication system>
Hereinafter, a case of notifying the mobile phone of an object and a person approaching the mobile phone carrying the first mobile terminal 2 will be described. The same components as those in the above-described embodiment, the first modification, or the second modification are designated by the same reference numerals, and the description thereof will be omitted or simplified.

FIG. 40 is a diagram showing an example of the configuration of the first mobile terminal 2B according to the third modification of the embodiment. As shown in FIG. 40, the first mobile terminal 2B includes a communication unit 21, a radar 22, a microphone 23, a position detection unit 24, a vibrator 25, a speaker 26, a display unit 27, and an acceleration sensor 28. , The control unit 29B is provided.

The control unit 29B includes, for example, an approach determination unit 291 as a functional unit in addition to the configuration provided in the control unit 29. The control unit 29B is realized by, for example, a hardware processor such as a CPU executing a program (software) stored in a storage unit (not shown). Further, some or all of these components may be realized by hardware (including a circuit unit) such as LSI, ASIC, FPGA or GPU, or may be realized by collaboration between software and hardware. May be good.

The approach determination unit 291 determines, for example, whether or not an object existing around the carrier has approached the carrier based on the detection result of the detection function provided in the first mobile terminal 2B. In the following description, a case where the detection function included in the first mobile terminal 2B is the radar 22 will be described.

FIG. 41 is a diagram schematically showing the start timing of the notification according to the third modification of the embodiment. The radar 22 included in the first mobile terminal 2B is configured to be able to detect the surroundings of the child C1, for example. The radar 22 is composed of, for example, a plurality of (two in the figure) millimeter-wave radars, and is provided in different directions so that the periphery of the first mobile terminal 2B (that is, the periphery of the child C1) can be detected. .. In the example shown in FIG. 41, the front radar 209 and the rear radar 211 included in the radar 22 detect different ranges (front detection range AF and rear detection range AR shown). When the radar 22 is set so that the circumference of the child C1 can be detected over the entire area (for example, a range of 360 degrees around the vertical axis), the front detection range AF and the rear detection range AR may overlap each other. Good. For example, the radar 22 detects the surroundings of the mobile phone at predetermined time intervals and generates a detection signal. The radar 22 may include one or a plurality of millimeter-wave radars as long as it can detect the surroundings of the child C1.

The first mobile terminal 2B may be provided with a device other than the radar 22 as a configuration for detecting the surrounding environment of the mobile phone. The first mobile terminal 2B may include a camera, LIDAR (Light Detection and Ranging or Laser Imaging Detection and Ranging), an infrared sensor, or the like instead of the radar 22.
For example, the first mobile terminal 2B may include one or more cameras instead of the radar 22. For example, as shown in FIG. 41, the three cameras provided in the first mobile terminal 2B image different ranges (imaging ranges AR1 to AR3 shown). The imaging ranges AR1 to AR3 of the three cameras may be superimposed on each other. The three cameras may image the surroundings of the mobile phone at predetermined time intervals and generate a captured image (for example, a still image or a moving image).

Based on the detection signal generated by the radar 22, the approach determination unit 291 moves the object to a position (that is, a predetermined range ARC shown) separated by a predetermined distance (second predetermined distance dt2 shown) from the position of the child C1. When approaching, it is determined that the object has approached the child C1 and the detection signal of the radar 22 is transmitted to the data center 4B. The second predetermined distance dt2 is a distance of about several meters.

The notification unit 421 of the data center 4B controls the notification function provided in the first mobile terminal 2B when an object is approaching the child C1 based on the detection signal of the radar 22 received from the first mobile terminal 2B. Notify child C1 of the approach of an object. The notification unit 421 notifies the child C1 of the approach of the vehicle m and the approach of the suspicious person among the objects approaching the child C1.

FIG. 42 is a flowchart showing an example of processing of the approach determination unit 291 and the notification unit 421 according to the third modification of the embodiment.
First, the approach determination unit 291 acquires the detection signal output by the radar 22 (step S300).
Next, the approach determination unit 291 determines whether or not the distance from the child C1 to the detected object is less than the second predetermined distance dt2 based on the acquired detection signal (step S302).
When the approach determination unit 291 determines that the distance from the child C1 to the detected object is not less than the second predetermined distance dt2 (NO side of step S302), the process returns to step S300 and stands by.
On the other hand, when the approach determination unit 291 determines that the distance from the child C1 to the detected object is less than the second predetermined distance dt2 (YES side of step S302), the process proceeds to step S304.
Then, the notification unit 421 performs an object approach notification process for notifying the child C1 of the approach of the object (step S304), and ends the process.

FIG. 43 is a flowchart showing the details of the object approach notification process in step S304 shown in FIG. 42.
First, the notification unit 421 determines whether or not the size of the object indicated by the detection signal acquired in step S300 is equal to or larger than a predetermined size (step S400). The predetermined size is, for example, a general suitable vehicle size.
When the notification unit 421 determines that the size of the object indicated by the detection signal is equal to or larger than a predetermined size (YES side in step S400), the notification unit 421 proceeds to the process in step S402.
On the other hand, when the notification unit 421 determines that the size of the object is not larger than the predetermined size, the processing proceeds to step S410.
Then, the notification unit 421 determines that the object is the vehicle m (step S402).
Next, the notification unit 421 acquires a detection signal output after the detection signal acquired in step S300 (step S404).

Next, the notification unit 421 determines whether or not the speed of the vehicle m is equal to or higher than the predetermined speed based on the detection signal acquired in step S300 and the detection signal acquired in step S404 (step S406). ). The predetermined speed is, for example, a speed of several to several tens of km / h.
When the speed of the vehicle m is not equal to or higher than the predetermined speed (NO side of step S406), the notification unit 421 proceeds to step S408.
On the other hand, when the notification unit 421 determines that the speed of the vehicle m is equal to or higher than a predetermined speed (YES side in step S406), the notification unit 421 proceeds to the process in step S412.
Then, the notification unit 421 determines whether or not the vehicle m has passed the vicinity of the child C1 (step S408).
When the vehicle m finishes passing in the vicinity of the child C1 (YES side in step S408), the notification unit 421 estimates that the child C1 is not in danger and starts a notification to notify the child C1 that the vehicle m is approaching. No, the process ends.
On the other hand, when the notification unit 421 determines that the vehicle m has not finished passing in the vicinity of the child C1 (NO side in step S408), the processing returns to step S404. When repeating steps S404 to S406, the notification unit 421 estimates that if the vehicle m approaching the child C1 is not at a predetermined speed or higher (NO side of step S406), the child C1 is not at risk even if the vehicle approaches. , Does not start notification.

Further, the notification unit 421 determines whether or not the movement pattern of the object matches the pattern of the suspicious person (step S410). The pattern of the suspicious person is, for example, a pattern in which a specific object is encountered more than a predetermined number of times during a unit period related to the movement of the child C1 (for example, while attending school or leaving school on an appropriate day). Further, the pattern of the suspicious person is, for example, a pattern in which the object reciprocates on a route matching the movement path of the child C1 during the unit period related to the movement of the child C1. Further, the pattern of the suspicious person is, for example, a pattern in which the characteristics of the object match the characteristics of the suspicious person in the suspicious person information.
When the notification unit 421 determines that the movement pattern of the object does not match the pattern of the suspicious person (NO side in step S410), the notification unit 421 estimates that the object is not a suspicious person and starts notification to notify the child C1 of the approach of the object. End the process without doing.
On the other hand, when the notification unit 421 determines that the movement pattern of the object matches the pattern of the suspicious person (YES side of step S410, that is, the object is a suspicious person), the processing proceeds to step S412.
Then, the notification unit 421 starts notification to notify the child C1 of the approach of the vehicle m or the suspicious person (step S412).

Next, the notification unit 421 acquires a detection signal output after the detection signal acquired in step S300 (step S414).
Next, the notification unit 421 determines whether or not the vehicle m or the suspicious person is approaching the child C1 based on the detection signal acquired in step S300 and the detection signal acquired in step S414 (step). S416).
When the vehicle m or the suspicious person is approaching the child C1 (YES side in step S410), the notification unit 421 proceeds to the process in step S418.
On the other hand, when the vehicle m or the suspicious person is not approaching the child C1 (NO side in step S410), the notification unit 421 proceeds to the process in step S420.

Then, the notification unit 421 increases the notification amount (step S418), and returns the process to step S416.
Further, the notification unit 421 determines whether or not the vehicle m or the suspicious person has finished passing in the vicinity of the child C1 (step S420).
When the notification unit 421 determines that the vehicle m or the suspicious person has not finished passing the vicinity of the child C1 (NO side in step S420), the processing is returned to step S416, and the processing of steps S416 to S418 is repeated.
On the other hand, when the vehicle m or the suspicious person finishes passing the vicinity of the child C1 (YES side in step S420), the notification unit 421 proceeds to the process in step S422.
The notification unit 421 stops the notification (step S422).

As described above, the information communication system 1B according to the third modification of the embodiment can more appropriately notify the child C1 of the approach of the vehicle m or the suspicious person.

<Fourth variant of information communication system>
The case of recognizing a predetermined operation of a mobile phone at a geographical position will be described below. The same components as those of the above-described embodiment, first modified example, second modified example, and third modified example are designated by the same reference numerals, and the description thereof will be omitted or simplified.

FIG. 44 is a diagram showing an example of the configuration of the first mobile terminal 2C according to the fourth modification of the embodiment.

The motion recognition unit 292 recognizes whether or not the mobile phone has performed a predetermined motion based on the detection result of the detection function (in this example, the radar 22) included in the first mobile terminal 2C, for example. The predetermined operation is preferably performed by the mobile phone at a geographical location. The predetermined operation is, for example, a stop operation of stopping at a geographical position. Further, the predetermined operation is, for example, a left-right confirmation operation for confirming the left and right at a geographical position. Further, the predetermined motion is, for example, a hand raising motion of raising a hand at a geographical position.
The detection range of the radar 22 includes the movable range of the head of the carrier and the movable range of the hand of the carrier. The motion recognition unit 292 recognizes a predetermined motion performed by the mobile phone based on the detection signal output by the radar 22, and transmits information indicating the recognized predetermined motion to the data center 4B.

FIG. 45 is a diagram schematically showing the timing of performing the recognition process of the predetermined operation according to the fourth modification of the embodiment. As described above, the first mobile terminal 2C starts the notification by the vibrator 25 at the position where the distance to the geographical position PT1 is less than the first predetermined distance dt1 (the position of the “child C1 at time t” in the figure). To do. In the example shown in FIG. 45, the child C1 performs a stop motion to stop at the geographical location PT1. Hereinafter, processing when the motion recognition unit 292 recognizes various predetermined motions will be described.

<When recognizing stop operation>
The motion recognition unit 292 transmits the position information acquired by the position detection unit 24 to the data center 4B. The data center 4B refers to the geographical position information stored in the storage unit 44B, and identifies the geographical position PT1 existing in the vicinity of the position of the child C1 indicated by the position information. The data center 4B transmits information indicating the specified geographical location PT1 to the first mobile terminal 2C. The motion recognition unit 292 determines whether or not the position of the child C1 specified by the position detection unit 24 is the geographical position PT1. Further, the motion recognition unit 292 recognizes that the child C1 is stopped when there is no change in the surrounding environment acquired by the detection signal for a predetermined time based on the detection signal output by the radar 22. The motion recognition unit 292 integrates the above-mentioned determinations, and recognizes that the stop motion has been performed when the child C1 is stopped at the geographical position PT1. The motion recognition unit 292 performs a process of recognizing the stop motion from the separated position separated from the geographical position PT1 by a predetermined distance (in the illustrated example, the third predetermined distance dt3) to the geographical position PT1. May be good. In this case, the motion recognition unit 292 specifies a separation position in front of the geographical position PT1 in the vicinity of the current position acquired from the data center 4B by a third predetermined distance dt3, and moves from the specified separation position to the geographical position PT1. The process of recognizing the stop operation may be performed until it arrives.

<When recognizing left / right confirmation operation>
Based on the detection signal output by the radar 22, the motion recognition unit 292 performs a left-right confirmation operation when the head (for example, a face) of the child C1 faces the child C1 to the left and right. Recognize that.

<When recognizing the raising hand movement>
Based on the detection signal output by the radar 22, the motion recognition unit 292 recognizes that the hand raising motion has been performed when the hand portion (for example, the palm) of the child C1 is positioned upward with respect to the child C1.

The motion recognition unit 292 transmits information indicating that the predetermined motion is recognized to the data center 4B at the timing when it recognizes that the predetermined motion has been performed. The notification unit 421 stops the notification when the notification for notifying the child C1 of the approach of the geographical position is started and the notification unit 292 receives the information indicating that the predetermined operation has been performed. ..

The motion recognition unit 292 may be able to recognize all of the predetermined motions (for example, stop motion, left / right confirmation motion, hand raising motion, etc.), or only a part of the predetermined motion (for example, left / right confirmation motion and hand raising motion). Etc.) may be recognizable.

FIG. 46 is a flowchart showing an example of the notification stop processing of the notification unit 421 according to the fourth modification of the embodiment.
First, the notification unit 421 determines whether or not the notification has been started (step S500).
If the notification is not started (NO side of step S500), the notification unit 421 repeats the process of step S500 and waits until the notification is started.
On the other hand, when the notification unit 421 has started the notification (YES side in step S500), the notification unit 421 proceeds to the process in step S502.
Then, the notification unit 421 determines whether or not the information indicating that the predetermined operation has been performed has been received from the first mobile terminal 2C (step S502).
When the predetermined operation is not performed (NO side of step S502), the notification unit 421 repeats the process of step S502 and waits until the information indicating that the predetermined operation has been performed is received.
On the other hand, when the notification unit 421 receives the information indicating that the predetermined operation has been performed (YES side in step S502), the notification unit 421 proceeds to the process in step S504.
Then, the notification unit 421 stops the notification (step S504).

As described above, the information communication system 1B of the fourth modification of the embodiment presumes that when the child C1 performs a predetermined action at a geographical position, the action necessary for traffic safety is presumed to be unnecessary. It is possible to suppress the continuation of the notification.

<About notification method>
In the second to fourth modifications described above, the case where the notification unit 421 vibrates the vibrator 25 to perform various notifications to the child C1 has been described, but the present invention is not limited to this. The notification may be performed, for example, by the speaker 26 outputting voice. In this case, increasing the notification amount is, for example, at least one of increasing the volume of the voice and increasing the frequency of the voice output.

<About recognition of moving speed>
Further, in the above-described fourth modification, the case where the motion recognition unit 292 recognizes the moving speed of the child C1 based on the detection signal output by the radar 22 has been described, but the present invention is not limited to this. The moving speed of the child C1 may be recognized, for example, based on the output of the acceleration sensor 28. In this case, the motion recognition unit 292 recognizes the moving speed of the child C1 by integrating the output of the acceleration sensor 28 and deriving the moving speed of the child C1.

<Notification based on moving speed>
Further, in the second to fourth modifications described above, the case where the notification unit 421 starts the notification based on the distance from the child C1 to the geographical position PT1 has been described, but the present invention is not limited to this. The notification unit 421 may perform notification based on the moving speed of the child C1. For example, when the moving speed of the child C1 is fast, the notification unit 421 may accelerate the start timing of the notification or increase the notification amount as compared with the case where the moving speed is slow. As a result, the information communication system 1B can promptly notify the child C1 who is likely to run and jump out on the road.

<Judgment of approach of geographical position>
Further, in the third modification and the fourth modification described above, the notification unit 421 approaches the geographical position PT1 based on the position information of the child C1 acquired by the position detection unit 24 and the geographical position information. The case of determining is described, but the present invention is not limited to this. The notification unit 421 derives the estimated arrival time of the geographical position PT1 based on the moving speed of the child C1, and determines whether or not the geographical position PT1 is approached based on the derived estimated arrival time. Good. In this case, the notification unit 421 derives the expected arrival time to arrive at the geographical position PT1 and determines whether or not the geographical position PT1 has approached based on the derived estimated arrival time.

<Regarding the setting of geographical position>
Further, in the above-described second to fourth modified examples, the case where the geographical position PT1 is predetermined and is stored as the geographical position information in the storage unit 44B has been described, but the present invention is not limited to this. .. The geographical location PT1 may be designated, for example, from the second mobile terminal 3 possessed by the guardian of the child C1. In this case, the second mobile terminal 3 executes the program (software) used when setting the geographical position PT1 as the program (software) stored in the storage unit (not shown) of the second mobile terminal 3. .. For example, by executing this program (software), the map image is displayed on the display unit 34. The guardian inputs the start position and the end position of the walking route when the child C1 goes to and from school in the reception unit (not shown) provided in the second mobile terminal 3. The reception unit is an operation device such as a button, a keyboard, and a mouse.
In the following description, the case where the reception unit is a touch panel integrally formed with the display unit 34 will be described. The second mobile terminal 3 superimposes a plurality of route rt candidates estimated that the child C1 walks on the map image based on the start position and the end position received by the reception unit, and presents them on the display unit 34. To do. The guardian selects the route rt in which the child C1 actually walks from among the plurality of route rt candidates presented.

Next, the reception unit accepts the operation of the guardian who specifies the geographical position PT1 at which the child C1 wants to perform a predetermined operation on the selected (designated) route rt. The information of the geographical position PT1 of the storage unit 44B includes information indicating the geographical position PT1 designated by the guardian. As a result, the information communication system 1B can notify the child C1 of the approach of the geographical position PT1 designated by the guardian.

The reception unit may specify the route rt on which the child C1 actually walks by inputting the position of the route rt on the displayed map image by the guardian tracing the position of the route rt on the touch panel. Further, when the position designated by the operation of the guardian (for example, the start position, the end position and the geographical position PT1 of the route rt) is not on the route rt or the sidewalk, the control unit 36 is in the vicinity of the specified position. It may be corrected to the position on the route rt or the sidewalk.

<Notification of predetermined operation>
Further, in the above description, the case where the notification unit 421 notifies the child C1 of the approach of the geographical position PT1 or the approach of the vehicle m or a suspicious person has been described, but the present invention is not limited to this. The notification unit 421 may, for example, perform notification for prompting a predetermined operation at the geographical position PT1. In this case, for example, when the approach determination unit 291 determines that the child C1 has approached the geographical position PT1, the notification unit 421 confirms "Pause at the intersection!" Or "Migi, folds" from the speaker 26. Then, raise your hand and cross the pedestrian crossing! ”, Etc. to give a notification prompting a predetermined action.

<Notification of evaluation result of predetermined operation>
Further, the notification unit 421 may notify the evaluation result of the predetermined operation performed by the child C1. In this case, when the notification unit 421 receives information indicating that the child C1 has performed a predetermined operation from the first mobile terminal 2C, the notification unit 421 may perform a notification praising the child C1. The notification praising the child C1 is a notification such that the vibrator 25 is vibrated by a predetermined rhythm, and the speaker 26 outputs a voice praising the child C1 saying "You can confirm right and left! Great!". ..
Further, the notification unit 421 may notify the child C1 to pay attention when the child C1 does not perform a predetermined operation at the geographical position PT1. The notification to pay attention to the child C1 is a notification such that the vibrator 25 is vibrated by a predetermined rhythm and the speaker 26 outputs a voice to pay attention to the child C1 saying "It is dangerous if it does not stop properly!". The notification unit 421 may notify the evaluation result of the predetermined operation every time the predetermined operation is performed, or every time the distance from the child C1 to the geographical position PT1 becomes less than the first predetermined distance dt1.

When the notification unit 421 notifies the geographical position PT1, the vehicle m, or the approach of a suspicious person, the notification unit 421 does not have to notify the evaluation result. As a result, the notification unit 421 can suppress the notification of the geographical position PT1 and the evaluation result from interfering with the notification of the vehicle m or the suspicious person.
Further, the notification unit 421 does not have to notify the evaluation result within a range within the first predetermined distance dt1 from the geographical position PT1. As a result, the notification unit 421 can prevent the notification of the evaluation result from interfering with the notification of the geographical position PT1, the vehicle m, or the suspicious person.

<About scoring of predetermined movements>
Further, the control unit 42B may be configured to score a predetermined operation performed by the child C1. The control unit 42B scores the predetermined motion performed by the child C1 based on whether the child C1 performs the predetermined motion at the geographical position PT1 or does not perform the predetermined motion, and provides information indicating the scoring result. It may be transmitted to the second mobile terminal 3 of the guardian. Further, the control unit 42B may transmit the scoring result of the predetermined operation to the second mobile terminal 3 each time the child C1 approaches the geographical position PT1.

<About information communication system 1B>
In addition, in the 2nd modification to the 4th modification described above, among the information communication system 1B, the configuration provided by the first mobile terminal 2, the first mobile terminal 2B or the first mobile terminal 2C and the configuration provided by the data center 4B. However, it is not limited to this. For example, the configuration provided in the first mobile terminal 2, the first mobile terminal 2B or the first mobile terminal 2C may be provided in the data center 4B, and the configuration provided in the data center 4B is the first mobile terminal 2, the first mobile terminal 2. 1 It may be provided in the mobile terminal 2B or the first mobile terminal 2C. Further, the information stored in the storage unit 44B may be stored in the storage unit (not shown) of the first mobile terminal 2, the first mobile terminal 2B, or the first mobile terminal 2C.
For example, in the second modification to the fourth modification described above, the notification unit 421 of the data center 4B stores the position information acquired by the position detection unit 24 of the first mobile terminal 2 and the storage unit 44B. The approach of the first mobile terminal 2 and the geographical position PT1 is determined based on the existing geographical position information, but the present invention is not limited to this. The approach determination unit 291 of each of the first mobile terminals 2B and 2C shown in the third modification and the fourth modification described above receives the geographical position information from the data center 4B, and the geographical position with the first mobile terminal 2. The approach of PT1 may be determined.

In the above-described embodiment and each modification, each of the first mobile terminals 2, 2B and 2C is provided with a radar 22 by a front radar and a rear radar, but the present invention is not limited to this, and instead of the radar 22, a camera and a lidar are provided. (Light Detection and Ranging or Laser Imaging Detection and Ranging) or an infrared sensor may be provided.

<Stop interrupt for notification>
An operation example of interrupt stop of notification by each of the first mobile terminals 2, 2B, 2C in the above-described embodiment and each modification will be described below. The same components as those of the above-described embodiment, first modified example, second modified example, third modified example, or fourth modified example are designated by the same reference numerals, and the description thereof will be omitted or simplified. Further, in the following, the information communication system 1B and the first mobile terminal 2 according to the second modification described above will be described as an example, but the same operation will be performed in the information communication systems 1 and 1A and the first mobile terminals 2B and 2C. May be executed.
FIG. 47 is a flowchart showing an operation example of interrupt stop of notification by the first mobile terminal 2 according to the second modification. For example, the control unit 29 of the first mobile terminal 2 repeatedly executes the processes of steps S600 to S604 shown below at predetermined timings.

First, whether the control unit 29 of the first mobile terminal 2 is executing notification by at least one of the speaker 35 and the vibrator 37 of the first mobile terminal 2 in response to the control by the notification unit 421 of the data center 4B. Whether or not it is determined (step S600).
When the notification is not being executed (NO side in step S600), the control unit 29 advances the process to the return.
On the other hand, when the notification is being executed (YES side in step S600), the control unit 29 advances the process to step S602.
Next, the control unit 29 determines whether or not the radar 22 of the first mobile terminal 2 has detected the execution of the predetermined notification interruption instruction operation by the mobile phone (step S602).
When the execution of the predetermined notification interruption instruction operation is not detected (NO side in step S602), the control unit 29 advances the process to the return.
On the other hand, when the execution of the predetermined notification interruption instruction operation is detected (YES side in step S602), the control unit 29 advances the process to step S604.
Next, the control unit 29 stops the notification by an interrupt process for interrupting the control by the notification unit 421 (step S604). Then, the process proceeds to return.

The predetermined notification interruption instruction operation is a signal by a predetermined operation of the portable person instructing the interruption of the notification executed under the control of the notification unit 421, and is an operation that can be detected by the radar 22. For example, the predetermined notification interruption instruction operation is a predetermined operation by the hand of the carrier. It is clear that the predetermined movement by the carrier's hand is clearly distinguished from the parts such as the face and neck that are always present around the shoulder of the carrier and the unconscious or daily normal hand movement of the carrier. This is a possible operation.
The predetermined notification interruption instruction operation is temporarily held by bringing a hand close to the radiation surface of the radar 22 (for example, the front radar 209) of the first mobile terminal 2 arranged around the shoulder of the carrier, for example. This is an operation of repeating the operation to be performed a predetermined number of times (for example, twice).
Further, in the other predetermined notification interruption instruction operation, for example, the hand is brought closer to the radiation surface of the radar 22 (for example, the front radar 209) of the first mobile terminal 2 arranged around the shoulder of the carrier. It is a series of operations of holding a hand over the radial surface for a predetermined time (for example, several seconds).
The control unit 29 uses the movement trajectory, the movement speed, and the holding of the hand in the predetermined movement of the hand as reference data for determining whether or not the movement of the hand detected by the radar 22 corresponds to the predetermined notification interruption instruction movement. Data that defines at least one of the positions and the like is stored in advance.

The control unit 29 may perform a predetermined notification interruption instruction operation that can be detected by the acceleration sensor 28 instead of the radar 22. For example, the predetermined notification interruption instruction operation is a predetermined operation for generating a predetermined acceleration pattern input to the acceleration sensor 28 by the hand of a portable person who comes into contact with the acceleration sensor 28. The predetermined motion by the hand of the carrier is an action of generating a predetermined acceleration pattern that can be clearly distinguished from the acceleration pattern that normally occurs unconsciously or on a daily basis of the carrier around the shoulder of the carrier. ..
The predetermined notification interruption instruction operation is, for example, an operation of hitting the first mobile terminal 2 arranged around the shoulder of the carrier with a strength equal to or higher than a predetermined value.
In addition, another predetermined notification interruption instruction operation is, for example, an operation of repeatedly hitting the first mobile terminal 2 arranged around the shoulder of the carrier over a predetermined number of times.
The control unit 29 uses a predetermined acceleration pattern generated in response to the predetermined movement of the hand as reference data for determining whether or not the movement of the hand detected by the acceleration sensor 28 corresponds to a predetermined notification interruption instruction operation. The data that specifies the above is stored in advance.

As described above, the control unit 29 controls the interruption of the notification executed by the control of the notification unit 421 according to the predetermined operation of the hand of the carrier detected by the radar 22 or the acceleration sensor 28. As a result, it is possible to easily control the stop of notification by accepting the input operation by the mobile phone without requiring an input operation member such as a button directly operated by the mobile phone, and excessive notification can be performed. It can be suppressed.

In addition, the notification can be accurately stopped by an input operation that can be clearly distinguished from the unconscious or daily normal hand operation of the mobile phone.
Further, by arranging the first mobile terminal 2 in the vicinity of the shoulder of the mobile phone, not only the input operation of the mobile phone but also the objects around the mobile phone can be detected by the radar 22, and the peripheral monitoring can be performed. Can be assisted. In addition, the portable person can easily perform a complicated hand input operation on the radar 22 and the acceleration sensor 28 in the vicinity of the shoulder portion. Further, the radar 22 and the acceleration sensor 28 can accurately detect the complicated movement of the hand of the portable person.

<Voice message processing>

You may control it. For example, a predetermined instruction operation is an operation by the hand of the mobile phone, and is discriminated from parts such as the face and neck that are always present around the shoulder of the mobile phone, and the unconscious or daily normal of the mobile phone. This is an operation that can be clearly distinguished from the movement of the hand.
As a predetermined instruction operation, the operation of instructing the speaker 26 to reproduce the voice message and the operation of instructing the microphone 23 to record the voice message are, for example, mutually symmetrical operations. For example, the instruction operation for instructing the reproduction of a voice message is performed outside the carrier so as to cross the radiation surface of the radar 22 (for example, front radar 209) of the first mobile terminal 2 arranged around the shoulder of the carrier. It is an action of waving from the inside. On the other hand, the instruction operation for instructing the recording of the voice message is performed inside the carrier so as to cross the radiation surface of the radar 22 (for example, the front radar 209) of the first mobile terminal 2 arranged around the shoulder of the carrier. It is an action of waving from to the outside.
The control unit 29 uses the movement trajectory, the movement speed, and the holding of the hand in the predetermined instruction movement of the hand as reference data for determining whether or not the movement of the hand detected by the radar 22 corresponds to the predetermined instruction movement. Data that defines at least one of the positions and the like is stored in advance.

As described above, the control unit 29 controls the start of reproduction and recording of the voice message in response to a predetermined movement of the hand of the carrier detected by the radar 22 or the acceleration sensor 28. As a result, it is possible to easily and quickly control the reproduction and recording of the voice message by accepting the input operation by the mobile phone without the need for an input operation member such as a button directly operated by the mobile phone. ..
