Description

[Technical Field]

[0001] The present disclosure relates to a notification device, a notification method, and a program for notifying a user that the user does not have an object in his or her possession. [Background technology]

[0002] An example of a notification device that notifies a user that an object is not in their possession is described in Patent Document 1. The misplacement prevention device described in Patent Document 1 is a misplacement prevention device that includes a portable wireless transceiver (notification device) with wireless transmission and reception capabilities and a wireless tag attached to the personal item (object). The portable wireless transceiver also includes a motion detection means that detects the movement of the wearer (user) carrying the personal item, and an RF module as a response detection means that accesses the wireless tag while the wearer is moving and detects whether or not there is a response from the wireless tag. The portable wireless transceiver also includes a transmission / reception antenna, a liquid crystal display, a buzzer, and an alarm unit. The motion detection means includes a reed switch and a movable magnet.

[0003] The motion detection means detects even the slightest movement of the wearer's body, not to mention when the wearer is walking. Specifically, when the wearer's body moves, the moving magnet vibrates (sways), and the reed switch opens and closes in response to the movement of the moving magnet. When the reed switch opens and closes, the RD module transmits the ID code from the portable wireless transceiver to the wireless tag.

[0004] When the wireless tag is out of communication range, that is, when the personal item is far from the person who owns the portable wireless transceiver, and the wireless tag does not return an ID code to the portable wireless transceiver even though the portable wireless transceiver has transmitted an ID code, the device determines that the personal item has been left behind, and the buzzer of the portable wireless transceiver sounds and the alarm unit emits light to notify the person that the personal item has been left behind.

[0039] When the non-transitory program is executed, the processing device 24 cooperates with the input device 27, the detection sensor 21, the communication device 25, and the memory 23 to implement a possession determination unit 24A, a movement determination unit 24B, a current location determination unit 24C, an activity schedule management unit 24D, a condition management unit 24E, a notification management unit 24F, and an artificial intelligence unit 24G. The possession determination unit 24A is configured to determine whether or not the user P1 is carrying the tag 10 based on the strength of the radio wave signal acquired by the communication device 25. The movement determination unit 24B is configured to determine whether or not the user P1 is moving based on the signal from the detection sensor 21, map data stored in the memory 23, a signal received from the artificial satellite B1, etc.

[0040] The current position determination unit 24C is configured to determine the actual behavior of the user P1 based on, for example, a signal from the detection sensor 21, map data stored in the memory 14, a signal received from the artificial satellite B1, etc. The actual behavior of the user P1 includes the current positions of the terminal device 20 and the user P1 on the map data, the actual movement route of the user P1, and the actual movement direction of the user P1.

The activity schedule of the user P1 includes items such as the date of the activity, the destination, the time of leaving home for the destination, and the time of returning home. The condition management unit 24E, in cooperation with the artificial intelligence unit 24G and the memory 23, realizes the function of determining target activity conditions that are compatible with the activity schedule of the user P1 and the function of determining whether the actual activity of the user P1 is consistent with the target activity conditions. The target activity conditions include information such as the target travel route from the user P1's home to the destination, the target travel route from the destination to the home, the travel direction when traveling from the home to the destination, and the travel direction when traveling from the destination to the home.

[0042] The notification management unit 24F has a function to determine whether to output a notification that "the actual behavior of the user P1 does not match the target behavior condition" on the output device 28 based on the determination result of whether the actual behavior of the user P1 matches the target behavior condition, and a function to determine an element for outputting the notification on the output device 28. The element for outputting the notification on the output device 28 includes a display, a speaker, a buzzer, a lamp, a vibrator, etc.

[0043] The artificial intelligence unit 24G is operated by a program and executes various processes in cooperation with the memory 23. The artificial intelligence unit 24G realizes a learning stage and an inference stage. In the learning stage of the artificial intelligence unit 24G, a learning model is trained in advance by performing machine learning, for example, supervised learning, to generate a learned model. The learning dataset used in supervised learning includes learning data and correct labels. The learning data includes information such as the location and destination of the user P1's home, information included in the user P1's activity plan, for example, a travel route connecting the home and the destination in the map data, and the user P1's travel direction on the travel route.

[0045] In the inference stage, the artificial intelligence unit 24G processes the input inference target data (information) using the trained model to output a predetermined inference result. In this embodiment, when the behavior schedule of the user P1 is input to the artificial intelligence unit 24 as the inference target data, the trained model can output a target behavior condition that matches the behavior schedule of the user P1 as the inference result.

[0046] In addition, in this embodiment, when the actual behavior of user P1 is input to the artificial intelligence unit 24G as data to be inferred, the trained model can output as an inference result whether or not the actual behavior of user P1 is consistent with the target behavior conditions.

[0047] The communication device 25 may be configured with, for example, an antenna and a GPS (Global Positioning System) receiver. The communication device 25 is configured to acquire signals, data, and information from external devices via the network C1, and transmit signals, data, and information to external devices via the network C1. The network C1 may be configured with a wireless communication line, for example, short-range wireless communication. Short-range wireless communication includes communication standards such as Bluetooth (registered trademark) and wireless LAN (Local area network). The distance over which communication is possible via short-range wireless communication is, for example, 100 meters or less.

[0048] Therefore, the tag 10 and the terminal device 20 can communicate with each other by short-range wireless communication via the network C1. If the communication device 25 has a GPS receiver, the communication device 16 can receive radio waves transmitted from the artificial satellite B1 via the network C1.

The display includes a liquid crystal display, an organic electroluminescence display, etc. Various screens, such as an operation screen and an information screen, are displayed on the display. Operation tabs, operation buttons, etc. are displayed on the various screens. By operating the input device 27, the user P1 can select an arbitrary predetermined location and register the selected predetermined location. The registered predetermined location is stored in the memory 23. The arbitrary predetermined location may be any of the location, address, land number, etc. in the map data. Examples of the arbitrary predetermined location include the user P1's home, workplace, etc.

[0053] The output device 28 is provided to display and notify various data and information to the user P1. The output device 28 is composed of one or more elements, such as a display, speaker, buzzer, lamp, and vibrator. The speaker and buzzer each output sound information in response to a control signal output from the processing device 24. The lamp is, for example, a light-emitting diode lamp, and the lamp is controlled to turn on, off, or blink in response to the control signal output from the processing device 24. The vibrator has a structure in which a weight (eccentric weight) with an offset center of gravity is attached to the shaft of an electric motor. The vibrator applies a constant, continuous or intermittent vibration to the main body of the terminal device 20 in response to the control signal output from the processing device 24. The display displays various screens, such as information screens. The display of the input device 27 and the display of the output device 28 may also be integrated.

[0054] (Example of how to notify non-possession) The non-possession notification methods performed by the notification system 30 include a first non-possession notification method and a second non-possession notification method. The first non-possession notification method is to notify the user P1, who is carrying the tag 10 but is not carrying the terminal device 20, of this fact via the tag 10. The second non-possession notification method is to notify the user P1, who is carrying the terminal device 20 but is not carrying the tag 10, of this fact via the terminal device 20.

[0055] (First method of notifying non-possession) First, the first non-possession notification method will be described with reference to the flowchart of FIG. 2. The processing device 15 of the tag 10 processes input signals, data, and information in step S10. The processing device 15 determines whether the user P1 is carrying the terminal device 20 in step S11. The processing device 15 may make the determination in step S11 based on the radio wave strength of the short-range wireless communication. For example, if the radio wave strength received by the communication device 16 from the communication device 25 exceeds a threshold, the processing device 15 can determine in step S11 that the user P1 is carrying the terminal device 20. On the other hand, if the radio wave strength received by the communication device 16 from the communication device 25 is equal to or less than the threshold, the processing device 15 can determine in step S11 that the user P1 is not carrying the terminal device 20. The radio wave strength threshold used by the processing device 15 in the determination in step S11 is stored in the memory 14.

[0056] Furthermore, if the distance between the current position of the tag 10 in the map data and the current position of the terminal device 20 in the map data acquired from the terminal device 20 is less than a predetermined distance, the processing device 15 can determine in step S11 that the user P1 is carrying the terminal device 20. On the other hand, if the distance between the current position of the tag 10 in the map data and the current position of the terminal device 20 in the map data acquired from the terminal device 20 is equal to or greater than a predetermined distance, the processing device 15 can determine in step S11 that the user P1 is not carrying the terminal device 20. The predetermined distance used by the processing device 15 in the determination of step S11 is stored in the memory 14.

[0057] In step S12, the processing device 15 determines whether the user P1 is moving. The processing device 15 may make the determination in step S12 by processing the signal from the detection sensor 12. The processing device 15 may also make the determination in step S12 based on the current position of the user P1 on map data estimated by processing the signal from the detection sensor 12.

[0058] Furthermore, in step S13, the processing device 15 may determine whether the current location of the user P1 on the map data determined by processing the signal from the detection sensor 12 is in a predetermined location where the user P1 is registered. The order of determination in steps S11, S12, and S13 above is not limited.

[0059] Then, if the processing device 15 determines No in step S11, Yes in step S12, and No in step S13, it executes the determination in step S14 and ends the notification method of Fig. 2. In step S14, the processing device 15 executes the determination to cause the notification device 11 to output information that the user P1 is not carrying the terminal device 20. For this reason, for example, in a case where the user P1 carries the tag 10 and the terminal device 20 and goes out from his / her home to a park, and leaves the terminal device 20 on a park bench, the notification device 11 of the tag 10 carried by the user P1 can notify that the user P1 is not carrying the terminal device 20, that is, that the user P1 has left the terminal device 20 behind.

[0060] In response to this, if the processing device 15 makes one or more of the following determinations, ie, a Yes determination in step S11, a No determination in step S12, and a Yes determination in step S13, it executes the determination in step S15 and terminates the notification method of Fig. 2. In step S15, it determines not to output a notification from the notification device 11. In other words, no notification is made that the user P1 does not have the terminal device 20. For example, when the user P1 is in a registered predetermined location, specifically, at home or at work, and moves around the predetermined location without having the terminal device 20, it is possible to prevent the notification device 11 from making an erroneous notification.

[0061] (Second method of notifying non-possession) Next, the second non-possession notification method will be described with reference to the flowchart of FIG. 2. The processing device 24 of the terminal device 20 processes input signals, data, and information in step S10. The processing device 24 determines whether the user P1 is carrying an object with the tag 10 attached in step S11. The processing device 24 may make the determination in step S11 based on the radio wave strength of the short-range wireless communication. For example, if the radio wave strength received by the communication device 25 from the communication device 16 exceeds a threshold, the processing device 24 can determine in step S11 that the user P1 is carrying a briefcase. On the other hand, if the radio wave strength received by the communication device 25 from the communication device 16 is equal to or less than the threshold, the processing device 24 can determine in step S11 that the user P1 is not carrying a briefcase. The radio wave strength threshold used by the processing device 24 in the determination in step S11 is stored in the memory 23.

[0062] Furthermore, if the distance between the current position of the terminal device 20 in the map data and the current position of the tag 10 in the map data acquired from the tag 10 is less than a predetermined distance, the processing device 24 can determine in step S11 that the user P1 is carrying a briefcase. On the other hand, if the distance between the current position of the terminal device 20 in the map data and the current position of the tag 10 in the map data acquired from the tag 10 is equal to or greater than a predetermined distance, the processing device 24 can determine in step S11 that the user P1 is not carrying a briefcase. The predetermined distance used by the processing device 24 in the determination of step S11 is stored in the memory 23.

[0063] In step S12, the processing device 24 determines whether the user P1 is moving. The processing device 24 may make the determination in step S12 by processing the signal from the detection sensor 21. The processing device 24 may also make the determination in step S12 based on the current position of the user P1 on map data estimated by processing the signal from the detection sensor 21.

[0064] Furthermore, in step S13, the processing device 24 may determine whether the current location of the user P1 on the map data estimated by processing the signal from the detection sensor 21 is in a predetermined location where the user P1 is registered. The order of the determinations in steps S11, S12, and S13 above is not limited.

[0065] If the processing device 24 determines No in step S11, Yes in step S12, and No in step S13, the process proceeds to step S14, where it causes the output device 28 to make a notification, thereby terminating the notification method of Fig. 2. In step S14, the output device 28 notifies the user P1 that he or she is not carrying the briefcase. For example, if user P1 goes out from his or her home to a park carrying a briefcase containing tag 10, and then leaves the briefcase on a park bench and moves on, the output device 28 of the terminal device 20 carried by user P1 can notify the user that he or she is not carrying the briefcase, that is, that the briefcase has been left behind.

[0066] In response to this, if the processing device 24 makes one or more of the following determinations, ie, a Yes determination in step S11, a No determination in step S12, or a Yes determination in step S13, the processing device 24 terminates the notification method of FIG. 2 via step S15. In step S15, no notification is made by the output device 28. That is, no notification is made that the user P1 does not have the briefcase containing the tag 10. For example, when the user P1 is in a registered predetermined location, specifically, at home or at work, and the user P1 moves around the predetermined location without the briefcase containing the tag 10, this can prevent the output device 28 from erroneously outputting a notification.

[0067] (Another example of notification method 1) 3 shows another example 1 of the notification method that can be executed when the user P1 leaves home for a destination and when the user P1 returns from a destination to the destination. The user P1 can input the user P1's planned activities by operating the input device 27 of the terminal device 20 in step S20. The processing device 24 In step S20, the inputted action plan is processed and judged, and the judged action plan is The activity schedule includes items such as the date of the activity, the destination, the time of leaving home to the destination, and the time of returning home from the destination. An application for managing these activity schedules, such as a management calendar, is acquired by the terminal device 20 from an external device via the network C1. The management calendar is stored in the memory of the external device 31 connected to the network C1, and the terminal device 20 can access the external device 31 to acquire the management calendar.

[0068] In step S21 following step S20, the processing device 24 refers to map data stored in the memory 23, processes the user P1's behavior plan using the learned model, and so on, to infer, that is, determine, target behavior conditions that match the behavior plan, and stores the determination results in the memory 23. The target behavior conditions that match the behavior plan include information such as a target travel route from home to the destination, a target travel route from the destination to home, a travel direction when traveling from home to the destination, and a travel direction when traveling from the destination to home.

[0069] A plurality of candidates may be extracted for each of the target travel route from home to the destination and the target travel route from the destination to home. The processing device 24 may output the extracted plurality of target travel routes from the output device 28. Then, the user P1 may operate the input device 27 to select one of the plurality of candidates for the target travel route from home to the destination, and may select one of the plurality of candidates for the target travel route from the destination to home.

[0070] When the user P1 leaves his / her home carrying the tag 10 and the terminal device 20 after step S21, the processing device 24 The actual behavior of the user P1 is determined in step S22. The actual behavior of the user P1 is determined as follows:The determination may be made by either the terminal device 20 or the tag 10. The result of the determination made by the tag 10 is sent from the tag 10 to the terminal device 20 via short-range wireless communication that constitutes the network C1.

[0071] In step S23, the processing device 24 of the terminal device 20 determines whether the actual behavior of the user P1 matches the target behavior conditions based on the behavior schedule of the user P1, the current position and actual movement route of the tag 10, the actual movement direction of the user P1, etc. If the determination in step S23 is No, the processing device 24 proceeds to step S24, determines to cause the output device 28 to output a notification that "the actual behavior of the user P1 does not match the target behavior conditions," and ends the notification method of FIG.

[0072] If the determination in step S23 is Yes, the processing device 24 executes the determination in step S25 and terminates the notification method of Fig. 3. In step S25, the processing device 24 executes the determination not to cause the output device 28 to output a notification.

[0073] (Another example of notification method 2) 4 shows another example 2 of the notification method. In step S30, user P1 attaches tag 10 to an object. Furthermore, the objects that user P1 needs when going out from home differ depending on user P1's planned activities. Furthermore, in step S30, user P1 operates input device 27 of terminal device 20 to input the objects that are needed based on the planned activities and the identification information of the tag 10 attached to the objects. The data and information input by operating input device 27 of terminal device 20 are stored in memory 23.

[0074] Furthermore, in step S31, the user P1 operates the input device 27 of the terminal device 20 to input the user P1's planned activities. The operation in step S31 is the same as the operation in step S20 in FIG. 3. The processing device 24 also processes the planned activities input in step S31 as Make a decision and then decide on a course of action. The data is stored in the memory 23 of the terminal device 20.

[0075] In step S32 following step S31, the processing device 24 selects objects that the user P1 needs when going out from home based on the user P1's planned activities. Judgment Data and information indicating the relationship between the user P1's planned activities and the objects that the user P1 needs when going out from home is stored in advance in the memory 23. For example, if the user P1's planned activities are to go shopping at a supermarket, a wallet, an eco bag, etc. are stored as the objects that the user P1 needs. Also, if the user P1's planned activities are to go to work, a pass case, a wallet, a briefcase, etc. are stored as the objects that the user P1 needs.

[0076] In step S33, the processing device 24 determines whether the user P1 is "in possession of the necessary object" when the user P1 has left home while carrying the terminal device 20. The processing device 24 determines that the user P1 has left home while carrying the terminal device 20 from the current position of the user P1 in map data estimated from a signal from the detection sensor 21 of the terminal device 20. The processing device 24 can also determine whether the user P1 is in possession of the object in the same manner as the determination in step S11 of FIG. 2 described in the second non-possession notification method.

[0077] The object that user P1 needs to take when he or she leaves home has been determined as explained in step S32, and it is possible to determine which object the tag 10 is attached to by the operation and processing in step S30. Therefore, in step S33, the processing device 24 can determine whether or not the object that the user P1 is carrying is a "necessary object."

[0078] If the determination in step S33 is No, the processing device 24 executes the determination in step S34 and terminates the notification method of Fig. 4. In step S34, the processing device 24 determines whether to output a notification from the output device 28. Therefore, the output device 28 outputs a notification that the user P1 does not have the required object.

[0079] In contrast, if the processing device 24 determines Yes in step S33, the processing device 24 executes the determination in step S35 and ends the notification method of Fig. 4. In step S35, the processing device 24 executes the determination not to output a notification on the output device 28. When the notification method of Fig. 4 is executed, when the user P1 goes out from home, the user P1 can recognize that he or she has left behind an object that is necessary according to his or her planned activities at home.

[0080] (Effects of this embodiment) According to this embodiment, it is possible to prevent the tag 10 or the terminal device 20 from notifying that the user P1 does not have an object in a situation where notification is not required by the tag 10 or the terminal device 20. In other words, the processing devices of the tag 10 and the terminal device 20 can determine whether or not to notify the user P1 that the user P1 does not have an object by the notification device depending on the environment of the user P1. Therefore, it is possible to match the relationship between the environment of the user P1 and whether or not to notify by the notification device.

[0081] Furthermore, the processing device 24 of the terminal device 20 determines whether the current location of the user P1 deviates from the target moving route, and based on the determination result, determines whether to output a notification on the output device 28. Therefore, the user P1 can be notified that the moving route of the user P1 deviates from the target moving route.

[0082] Furthermore, the processing device 24 of the terminal device 20 can determine whether the user P1 has a necessary object based on the user P1's planned activities, and based on the determination result, determine whether to output a notification on the output device 28. Therefore, the object possessed by the user P1 can be matched with the user P1's planned activities. For example, it can be prevented that the user P1 leaves home forgetting to have an object with him / her.
