Based on the control of the control unit 13, the vibration unit 193 notifies the user of the results of the pairing process and the determination process by vibration.

(Pairing process)
Next, the pairing process between the article-side device 30A and the portable device 10A will be described using the flowcharts of FIGS. 3 (A) and 3 (B). The pairing process is a process that is performed when the user registers his / her own items such as umbrellas and shoes that he / she does not want to mistake with others or is easily mistaken for the portable device 10A.

  FIG. 3A is a flowchart illustrating an example of processing executed by the control unit 13 of the mobile device 10A, and FIG. 3B is a flowchart illustrating an example of processing executed by the control unit 33 of the article-side device 30A. It is. In the present embodiment, the process of FIG. 3A is performed by carrying the portable device 10A set by the user in the “initial setting mode” and holding an article (umbrella, shoes) to be paired in his / her hand. When the human body communication between the portable device 10A and the article-side device 30A is established (see FIG. 2B), the process is started.

  In the process of FIG. 3A, first, in step S11, the control unit 13 of the mobile device 10A requests the article-side device 30A to transmit an ID number using human body communication.

  On the other hand, the control unit 33 of the article-side device 30A stands by until an ID number transmission request is received from the portable device 10A in step S31 of FIG. When the control unit 33 receives the ID number transmission request, the control unit 33 proceeds to step S33.

  If transfering to step S33, the control part 33 will transmit the ID number of the goods side apparatus 30A memorize | stored in the memory | storage part 31 with respect to 10 A of portable apparatuses (human body communication), and will return to step S31.

  On the other hand, in FIG. 3A, the control unit 13 requests the article-side device 30A to transmit the ID number, and then determines whether or not the ID number is received from the article-side device 30A in step S13. When determination here is denied, the control part 13 transfers to step S15, and determines whether predetermined time (for example, 10 second) passed. If the predetermined time has not elapsed, the control unit 13 returns to step S13.

  If the predetermined time has elapsed without receiving the ID number, that is, if the determination in step S13 is negative and the determination in step S15 is positive, the control unit 13 proceeds to step S17. In step S17, the control unit 13 notifies that the ID number cannot be received, and proceeds to step S23. Specifically, the control unit 13 outputs a voice message “The ID number of the article-side device 30 </ b> A cannot be received” from the speaker 192 or displays a similar message on the display unit 191. Do. Further, the control unit 13 may perform the notification by vibrating the mobile device 10 </ b> A by the vibration unit 193.

  On the other hand, if the ID number is received before the predetermined time has elapsed, that is, if step S13 is affirmed before the determination in step S15 is affirmed, the control unit 13 proceeds to step S19. In step S <b> 19, the control unit 13 stores the received ID number in the storage unit 12. Thereby, the pairing information table shown in FIG. 4 is updated. The pairing information table includes an ID number item, and the ID number of the article-side device 30A received in step S13 is stored in the ID number item. Note that the pairing information table shown in FIG. 4 stores only one ID number. However, in this embodiment, the pairing information table is provided on the article side provided for each of umbrellas, shoes, bags, and the like. The ID number of the device 30A, that is, a plurality of ID numbers can be stored.

  In subsequent step S21, the control unit 13 informs that the pairing has been normally performed, and proceeds to step S23. Specifically, the control unit 13 performs notification by outputting a sound “Pairing has been completed normally” from the speaker 192 or displaying a similar message on the display unit 191. Moreover, the control part 13 may perform the said notification by vibrating 10 A of portable apparatuses by the vibration part 193 by the aspect different from the aspect of the vibration used by step S17.

  If transfering it to step S23, the control part 13 will judge whether the instruction | indication which complete | finishes initial setting mode was received from the user. When determination here is denied, the control part 13 returns to step S11. On the other hand, when an instruction to end the initial setting mode is received from the user, the control unit 13 ends the process of FIG.

  Through the above pairing process, the user can easily register the information of the article-side device 30A attached to the article (an umbrella in the present embodiment) that is not mistaken for others in the storage unit 12 of the portable device 10A. . That is, the pairing between the mobile device 10A and the article-side device 30A can be easily performed. When the portable device 10A has an electronic payment function, the registration of the portable device 10A to the storage unit 12 is performed by using the electronic payment function to purchase the article-side device 30A and touch the article-side device 30A. May be. Alternatively, when the article-side device 30A is purchased, the communication unit 32 is set in a communicable state (communication is disabled before sales), and the user determines a predetermined location (based on the output of the position detection unit 17 of the portable device 10A) For example, it may be performed at the timing when the object side device 30A is touched at home).

(Determination process)
Next, using the flowcharts shown in FIGS. 5A and 5B, determination processing for determining whether or not an article selected by the user from a plurality of similar articles is the user's property. Will be described. In the present embodiment, the process of FIG. 5A is carried by the user carrying the portable device 10A set to the determination mode by the user and holding the article with the paired article-side device 30A. When the human body communication between the mobile device 10A and the article-side device 30A is established by attaching the device, the process of FIG. 5A is started. Instead of setting the mobile device 10A to the determination mode, when the user is away from the predetermined location (for example, home) by a predetermined distance (when going out), the human body communication between the mobile device 10A and the article-side device 30A is performed. If established, the process of FIG. 5A may be started.

  Hereinafter, as an example, it is raining, and as shown in FIG. 2 (B), the user carries the portable device 10A set to the determination mode and includes the article-side device 30A paired with the portable device 10A. The case of going to a drinking party with the umbrella 60A will be described.

  In the process of FIG. 5A, first, in step S41, the control unit 13 of the mobile device 10A determines whether communication with the article-side device 30A has been disconnected. While the user is moving to the drinking party, the user holds the umbrella 60A. Therefore, human body communication is established between the portable device 10A and the article-side device 30A, and the determination in step S41 is repeated. It is. Then, when the user arrives at the drinking party, puts the umbrella 60A into the umbrella stand 92 shown in FIG. 2C, and releases the handle 61 of the umbrella 60A, the portable device 10A and the article-side device 30A are separated. Will be disconnected. In this case, the determination in step S41 is affirmed, and the process proceeds to step S42. When the article-side device 30A is provided on the shoe, the determination in step S41 is affirmed when the user takes off the shoe.

  When the process proceeds to step S42, the control unit 13 acquires the position information of the user (mobile device 10A) from the position detection unit 17, acquires the date / time information from the calendar unit 18, and the communication is disconnected from the acquired information. The information is stored in the storage unit 12 in association with the ID number of the article-side device 30A. In the present embodiment, the control unit 13 positions the ID number “A12345” of the article-side device 30A paired with the portable device 10A in the pairing information table at a position where communication with the article-side device 30A is interrupted ( (Latitude, longitude) and date and time are stored in association with each other (see FIG. 6).

  Next, the control unit 13 detects the timing at which communication between the mobile device 10A and the article-side device 30A is to be established by the determination processing in steps S43 to S45. Here, after the user has finished the drinking party, as shown in FIG. 2C, a plurality of umbrellas (an umbrella 60A including the article-side device 30A and an umbrella not including the article-side device 30A) housed in the umbrella stand 92. 60B), the umbrella 60A including the article-side device 30A is taken up.

  First, in step S43, the control unit 13 determines whether or not a predetermined operation of the user (for example, picking up an umbrella, putting on shoes, etc.) is detected. Here, the control unit 13 recognizes the user's operation based on the acoustic data collected by the microphone 14 and the acceleration of the mobile device 10A detected by the acceleration sensor 16, and whether the recognized operation is a predetermined operation. Judge whether or not. Note that the motion recognition based on the acoustic data and acceleration uses, for example, the method described in the document “Kazunari Ouchi, Miwako Doi, ActivityAnalyzer that recognizes daily living behavior with acceleration and sound, Interaction 2011”. Can do. In this embodiment, the control part 13 shall detect the operation | movement which a user picks up an umbrella. Here, since the user performed the operation of picking up the umbrella 60A, the determination in step S43 is affirmed, and the control unit 13 detects that the communication between the mobile device 10A and the article-side device 30A should be established. The process proceeds to S46. Note that the control unit 13 may recognize the user's operation using an image captured by the imaging unit 15 using a known image analysis technique.

  If transfering it to step S46, the control part 13 will judge whether the human body communication with the goods side apparatus 30A is materialized. As described above, when the user picks up the umbrella 60A including the article-side device 30A, the human body communication with the article-side device 30A is established, and therefore the determination in step S46 is affirmed. In this case, the control unit 13 proceeds to step S49.

  In step S49, the control unit 13 requests the article side device 30A to transmit the ID number.

  On the other hand, the control unit 33 of the article-side device 30A stands by until an ID number transmission request is received from the portable device 10A in step S61 in FIG. And the determination of step S61 is affirmed in the stage which received the transmission request of ID number from 10 A of portable apparatuses, and it transfers to step S63.

  If transfering it to step S63, the control part 33 will transmit the self ID number memorize | stored in the memory | storage part 31 to 10 A of portable apparatuses, and will return to step S61.

  Returning to FIG. 5A, the control unit 13 of the portable device 10A receives the ID number from the article-side device 30A in step S50. Next, in step S51, the control unit 13 determines whether or not the ID number received in step S50 is the ID number of the paired article-side device 30A. Specifically, the control unit 13 determines whether or not the ID number received in step S50 exists in the pairing information table of FIG. In other words, in step S51, it is determined whether communication with the paired article-side device 30A is established based on the received ID number.

  Here, if the determination in step S51 is negative, it means that the user picked up another person's umbrella including the article-side device 30A from the umbrella stand 92. In this case, the control unit 13 proceeds to step S48 and notifies the user that the user does not have his / her own umbrella (have another person's umbrella). At this time, the control unit 13 may display on the display unit 191 that the umbrella picked up by the user is not his / her possession, or that the user has mistaken the umbrella, or that the speaker 192 makes a warning sound. May be output, or the mobile device 10 </ b> A may be vibrated by the vibration unit 193.

  On the other hand, if the determination in step S51 is affirmed, it means that the user picks up his / her umbrella from the umbrella stand 92. In this case, the control unit 13 proceeds to step S52 and notifies the user that the picked-up umbrella is the user's umbrella (owned item). At this time, the control unit 13 may display on the display unit 191 that the umbrella picked up by the user belongs to the user, or cause the speaker 192 to output a sound different from the sound output in step S48. Alternatively, the mobile device 10A may be vibrated with a vibration different from the vibration mode of step S48. When the user picks up his / her umbrella, the user may not be notified. After the process of step S52, the control unit 13 returns to step S41.

  By the way, if the determination in step S46 is negative, that is, if human body communication with the article-side device 30A is not established, the control unit 13 proceeds to step S47, and a predetermined time (for example, 10 seconds) is reached. Judge whether or not it has passed. If the determination in step S47 is negative (if the predetermined time has not elapsed), the control unit 13 returns to step S46. On the other hand, when the determination in step S47 is affirmative (when a predetermined time has elapsed), the process proceeds to step S48. It should be noted that although the user has detected an action of picking up an umbrella (S43: affirmative), a predetermined time has passed without establishment of human body communication with the article-side device 30A (S47: affirmative) It means that an umbrella (another person's umbrella 60B) to which the article-side device 30A is not attached is taken up. Therefore, when the process proceeds to step S48, the control unit 13 notifies the user that the user does not have his / her own umbrella (has another person's umbrella), and then returns to step S46.

  By the way, when judgment of step S43 is denied, ie, when the control part 13 does not detect predetermined | prescribed operation | movement (operation | movement picking up an umbrella), the control part 13 transfers to step S44.

  In step S44, the control unit 13 determines whether or not the user has contacted the article-side device 30A (including one provided on another person's article (umbrella)), that is, human body communication with the article-side device 30A is established. Determine whether or not. If the determination here is affirmed, the control unit 13 proceeds to step S49, and executes the processing and determination after step S49 as described above. On the other hand, when the determination in step S44 is negative (when human body communication with the article-side device 30A is not established), the control unit 13 proceeds to step S45.

  If transfering it to step S45, the control part 13 will judge whether the user is the vicinity of the position where communication with the goods side apparatus 30A interrupted. Whether the user is in the vicinity of the position where the communication with the article-side device 30A is interrupted is determined based on the communication disconnection location information stored in the pairing information table (FIG. 6) and the position of the user acquired from the position detection unit 17. It can be judged by information. If the determination in step S45 is negative, the process returns to step S43. If the determination is positive, the control unit 13 proceeds to step S53.

  In step S45, the control unit 13 may determine whether or not a predetermined time (for example, one hour) has elapsed since the communication with the article-side device 30A was interrupted. Thereby, when a user passes the vicinity of the umbrella stand 92 in order to go to a toilet etc. in the middle of a drinking party, it can prevent that the process after step S53 will be performed. Whether or not a predetermined time has elapsed since the time when communication with the article-side device 30A was interrupted was acquired from the information on the communication disconnection date and time stored in the pairing information table shown in FIG. It can be determined from the time information.

  When the determination in step S45 is affirmed and the process proceeds to step S53, the control unit 13 determines whether or not human body communication with the article-side device 30A is established. When determination here is denied, the control part 13 progresses to step S54, and determines whether predetermined time (for example, 10 seconds) passed. If the determination in step S54 is affirmative (if a predetermined time has elapsed), the process proceeds to step S55. In addition, although it was determined that the user is in the vicinity of the position where the communication with the article-side device 30A was interrupted (S45: Yes), a predetermined time has passed without establishing human body communication with the article-side device 30A. (S54: Yes) means that the user has forgotten to take the umbrella. Therefore, when it transfers to step S55, the control part 13 alert | reports to a user that the user does not have his own umbrella, ie, has left the umbrella.

  On the other hand, when the human body communication with the article-side device 30A is established before the predetermined time elapses, that is, when the determination in step S53 is affirmed before the determination in step S54 is affirmed, the control unit 13 In the same manner as described above, the processing / determination after step S49 is executed.

  In this way, the process of FIG. 5A is repeated until the user cancels the determination mode.

  As described above in detail, according to the first embodiment, the portable device 10A held by the user is on the article side provided on the article (umbrella) used by the user through human body communication via the user. The communication unit 11 that communicates with the device 30A, the control unit 13 that detects the timing at which communication between the communication unit 11 and the article-side device 30A should be established, and the communication unit 11 when the control unit 13 detects the timing. And the article-side device 30A, that is, an article provided with the article-side device 30A paired with the portable device 10A based on whether communication between the communication unit 11 and the article-side device 30A is established.

  In the first embodiment, the communication state between the communication unit 11 and the article-side device 30A is determined based on whether or not the portable device 10A has received the ID number of the article-side device 30A. Accordingly, the control unit 13 can determine that the article provided with the article-side device 30A or the article provided with the article-side device 30A having an unpaired ID number is not the user's property. .

  In the first embodiment, the control unit 13 detects the user's operation based on the output of the microphone 14 or the acceleration sensor 16, and based on the user's operation, the communication unit 11 and the article-side device 30A. It detects the timing at which communication should be established. Thereby, when the control unit 13 detects a predetermined operation (such as lifting an umbrella), the article-side device 30A to which the user is paired is determined based on the communication state between the communication unit 11 and the article-side device 30A. Since it is determined whether or not the article is provided, a mistake is also reported when an article provided with the article-side device 30A and an article not provided with the article-side device 30A are mixed. can do.

  Further, in the first embodiment, the control unit 13 is based on the contact state between the user and the article-side device 30A (including those provided in the other person's property) that can communicate with the communication unit 11. Thus, the timing at which communication between the communication unit 11 and the article-side device 30A should be established is detected. Thereby, the control part 13 can perform the process which determines whether the articles | goods which a user has are a user's possession goods at the appropriate timing when the user touched the goods side apparatus 30A. In this case, even when the control unit 13 cannot detect a predetermined operation (such as an operation of lifting an umbrella), the user-owned article is owned by the user at the timing when the article-side device 30A comes into contact with the user. Since it can be determined whether or not the product is a product, it is possible to reliably prevent the user from mistakenly taking the product.

  In the first embodiment, the mobile device 10A includes a position detection unit 17 that detects user position information, and the control unit 13 performs communication unit 11 and article-side device 30A based on the user position information.

Since it can be determined that the user has misplaced the article (umbrella 60A) including the article-side device 30A, the user can be notified of misplaced items.

  In the first embodiment, the article-side device 30A may be provided in advance in the article (sold in a state where the article-side device 30A is provided), and the user performs pairing processing. The performed article-side device 30A may be attached to its own property. Moreover, 10 A of portable apparatuses may not be multifunctional terminals, such as a smart phone, For example, the dedicated terminal provided only with the structure required for a mistake prevention may be sufficient. In this case, the user may purchase the paired portable device 10A and the article-side device 30A, attach the article-side device 30A to its own property, and carry the portable device 10A.

  In the first embodiment, the user may be able to delete data in the pairing information table as appropriate. As a result, it is not necessary to perform the determination process for the ID number of the article-side device 30A that is no longer used or is attached to the discarded article, so that the speed of the determination process can be improved. Further, an item name item may be provided in the pairing information table. Thereby, the user can grasp | ascertain which ID number is the ID number of 30 A of goods side apparatuses provided in which goods.

<< Second Embodiment >>
Next, a second embodiment will be described based on FIGS. 7 to 9B. The electronic device system 500B according to the second embodiment is a system used when a user rents a snowboard at a ski resort.

  As shown in FIG. 7, an electronic device system 500B according to the second embodiment includes a portable device 10B and an article-side device 30B.

(Portable device 10B)
In addition to the same configuration as the mobile device 10A of the first embodiment, the mobile device 10B includes a communication unit 21 for performing near field communication with the article-side device 30B such as Bluetooth (registered trademark) or Felica (registered trademark). ing. The communication unit 21 includes an antenna unit 211 and a communication control unit 212 for performing near field communication with the article-side device 30B.

(Article side device 30B)
The article-side device 30B has the same configuration as the article-side device 30A of the first embodiment, and also includes a communication unit 34 for performing near field communication such as Bluetooth (registered trademark) or Felica (registered trademark) with the portable device 10B. I have. The communication unit 34 includes an antenna unit 341 for performing near field communication with the mobile device 10B, and a communication control unit 342. In the present embodiment, as shown in FIG. 8A, the electrode part 321 for human body communication is provided at a position in contact with the user's hand when the user holds the snowboard 70A. In the present embodiment, not only when the user is a bare hand (that is, when the electrode part 321 is in contact with the hand) but also when the user is wearing a glove (ie, the electrode part 321 faces the hand). However, human body communication is possible.

(Pairing process)
In the second embodiment, it is assumed that an article-side device 30B attached to a snowboard rented by a user at a ski resort is paired with a portable device 10B. In the pairing process of the second embodiment, the pairing between the mobile device 10B and the article-side device 30B may be performed using human body communication as in the first embodiment, or using proximity communication. You may go. The other processes are the same as the pairing process (FIGS. 3A and 3B) of the first embodiment, and thus the description thereof is omitted.

(Determination process)
FIG. 9A and FIG. 9B are flowcharts showing the determination process in the second embodiment. Hereinafter, the determination process will be described in detail by taking as an example a case where the user searches for a snowboard rented out of a large number of snowboards. In the process of FIG. 9A, the user carries the portable device 10B set in the determination mode, and the proximity communication between the portable device 10B and the article-side device 30B paired with the portable device 10B is performed. It will be started when it is established (when the user starts using the snowboard 70A). Instead of setting the determination mode in the mobile device 10B, when the user holding the mobile device 10B is away from the predetermined location (for example, a rental shop) by a predetermined distance, the mobile device 10B is paired with the mobile device 10B. When the proximity communication with the article-side device 30B is established, the process of FIG. 9A may be started.

  In the process of FIG. 9A, first, in step S101, the control unit 13 determines whether or not the proximity communication with the paired article-side device 30B has been disconnected. In this process, it is determined whether or not the user has interrupted the use of the snowboard provided with the article-side device 30B. For example, it is assumed that the user removes the snowboard from the foot in front of the restaurant and eats the lunch as shown in FIG. In this case, since the proximity communication with the article-side device 30B is disconnected, the determination in step S101 is affirmed, and the control unit 13 proceeds to step S103.

  In step S103, the control unit 13 acquires the position information of the user (mobile device 10B) from the position detection unit 17, acquires the date / time information from the calendar unit 18, and pairs the acquired information with the mobile device 10B. It is stored in the storage unit 12 in association with the ID number of the article-side device 30B being ringed (see FIG. 6).

  Next, in step S105, the control unit 13 waits until it detects a timing at which close communication between the mobile device 10B and the article-side device 30B is to be established. In the present embodiment, when the user leaves the restaurant, the control unit 13 detects that it is time to establish near field communication between the mobile device 10B and the article-side device 30B. The control unit 13 determines whether or not the user has left the restaurant based on the location information of the restaurant stored in advance in the storage unit 12 and the location information of the user acquired from the location detection unit 17. Can do. Here, it is assumed that the user has finished eating at the restaurant and has gone out of the restaurant. In this case, the determination in step S105 is affirmed, and the process proceeds to step S107.

  If transfering it to step S107, the control part 13 will display on the display part 191 the position where communication with the goods side apparatus 30B was interrupted. For example, the control unit 13 may display a map on the display unit 191 and display a position where communication is interrupted on the map. Thereby, since the user can grasp the position where the snowboard is placed, the user can easily find his / her snowboard.

  Next, in step S109, the control unit 13 notifies the communication state of the near field communication with the article side device 30B. For example, when the proximity communication is performed by Bluetooth (registered trademark), the control unit 13 displays on the display unit 191 “out of communication range with the article side device 30B”, “communication with the article side device 30B”. By displaying “within range” or the like, the user can know whether or not he / she is approaching his / her own snowboard. For example, when proximity communication is performed using RFID, the control unit 13 may output a sound corresponding to the strength of communication with the article-side device 30B from the speaker 192. Thereby, the user can know whether or not he / she is approaching his / her snowboard by the sound output from the speaker 192, and it is easy to search for the snowboard.

  Next, in step S111, the control unit 13 determines whether or not a timing at which human body communication with the article-side device 30B is to be established is detected. In this case, for example, when the control unit 13 recognizes the user's action based on the acoustic data collected by the microphone 14 and the acceleration of the mobile device 10B detected by the acceleration sensor 16, the action is to pick up the snowboard. It is determined that the timing at which the human body communication between the portable device 10B and the article-side device 30B should be established is detected. Here, as shown in FIG. 8B, from among a plurality of snowboards (snowboard 70A provided with the article-side device 30B, snowboard 70B not provided with the article-side device 30B) that the user leans against the rack, It is assumed that the snowboard 70B is taken up as shown in FIG. In this case, the determination in step S111 is affirmed, and the process proceeds to step S113.

  If transfering it to step S113, the control part 13 will judge whether the human body communication with the goods side apparatus 30B is materialized. When determination here is denied, it progresses to step S115 and the control part 13 determines whether predetermined time (for example, 10 second) passed. When judgment here is affirmed, it transfers to step S117. As shown in FIG. 8C, when the user picks up the snowboard 70B that does not include the article-side device 30B, a predetermined time elapses without establishing human body communication with the article-side device 30B. The control unit 13 proceeds to step S117.

  If transfering it to step S117, the control part 13 alert | reports to a user that the user has mistakenly took the snowboard, and returns to step S113. At this time, the control unit 13 may display on the display unit 191 that the snowboard taken up by the user belongs to another person, may output a warning sound from the speaker 192, or may vibrate. The portable device 10B may be vibrated by the unit 193. Thereby, the user can know that the snowboard taken up is not his / her own. Hereinafter, the description will be continued assuming that the user who recognizes that the taken-up snowboard is not his / her own, returns the snowboard 70B to the rack and takes up the snowboard 70A including the article-side device 30B.

  When the user picks up the snowboard 70A including the article-side device 30B and the determination in step S113 is affirmed, the control unit 13 proceeds to step S119. If transfering it to step S119, the control part 13 will request | require transmission of ID number to the goods side apparatus 30B.

  On the other hand, the control unit 33 of the article-side device 30B stands by until an ID number transmission request is received from the portable device 10B in step S131 of FIG. 9B. Therefore, when the control unit 33 receives the transmission request for the ID number from the mobile device 10B, the determination in step S131 is affirmed, and the process proceeds to step S133. If transfering it to step S133, the control part 33 will transmit the own ID number memorize | stored in the memory | storage part 31 to the portable apparatus 10B, and will return to step S131.

  Returning to FIG. 9A, the control unit 13 of the portable device 10B receives the ID number from the article-side device 30B in step S121. Next, in step S123, the control unit 13 determines whether or not the ID number received in step S121 is the ID number of the paired article-side device 30B (whether or not it exists in the pairing information table). . That is, the control unit 13 determines whether or not human body communication with the paired article-side device 30B is established.

  If the determination in step S123 is negative, it means that the user picked up another person's snowboard equipped with the article-side device 30B. In this case, the control unit 13 proceeds to step S117 and notifies the user that the snowboard is mistaken.

  On the other hand, if the determination in step S123 is affirmative, it means that the user picked up his / her snowboard. In this case, the control unit 13 proceeds to step S125 and notifies the user that the taken-up snowboard belongs to the user (no mistake). At this time, the control part 13 may display that on the display part 191, and may output the sound different from the sound output by step S117 from the speaker 192. Or the control part 13 may vibrate the portable apparatus 10B by the vibration different from the aspect of the vibration of step S117. After the process of step S125, the control unit 13 returns to step S101.

  In this way, the process of FIG. 9A is repeated until the user cancels the determination mode.

  As described above in detail, according to the second embodiment, the mobile device 10B held by the user is connected to the communication unit 11 that communicates with the article-side device 30B by human body communication via the user, and the short distance. A communication unit 21 that communicates with the article-side device 30B by communication, a control unit 13 that detects timing at which communication between the communication unit 11 and the communication unit 21, and the article-side device 30B provided on the snowboard should be established; Whether or not the snowboard selected by the user based on the communication state between the communication unit 11 and the article-side device 30B is a snowboard provided with the paired article-side device 30B when the unit 13 detects the timing. And an informing unit 19 for informing the user. In this way, the article-side device 30B paired with the snowboard selected by the user is provided at an appropriate timing at which communication between the communication unit 11 and the communication unit 21 and the article-side device 30B provided on the snowboard should be established. Since it is notified whether or not it is a snowboard, it is possible to prevent a situation in which it is mistaken for another person's snowboard in the case of selecting one that has been rented from among many snowboards.

  In the second embodiment, the display unit 191, the speaker 192, and the vibration unit 193 have a display format, sound, vibration, and the like according to the communication state (communication strength) between the communication unit 21 and the article-side device 30 </ b> B. By changing the mode, the positional relationship (far and close) between the paired article-side device 30B and the user (mobile device 10B) is notified. Thereby, the user can know whether or not he / she is approaching his / her snowboard, and can reduce the time spent searching for the snowboard.

  Further, since the display unit 191 notifies the position where the communication between the communication unit 21 and the article-side device 30B is interrupted, the user can know the approximate position where the snowboard is placed, and can search for his / her own snowboard. The time spent can be reduced.

  In the second embodiment, the article-side device 30B is provided on the rental snowboard. However, the present invention is not limited to this. The user may provide the article-side device 30B on a snowboard owned by the user. Further, the present invention is not limited to snowboarding, and may be provided on skis, skiwear, skate shoes, bowling balls, and the like. Further, the mobile device 10B does not have a multi-function such as a smartphone, and may be a dedicated terminal having only a configuration necessary for preventing mistakes, for example. In this case, for example, a store clerk of the rental shop has paired the portable device 10B and the article-side device 30B in advance, and is paired with the article-side device 30B when renting a snowboard provided with the article-side device 30B. The portable device 10B may be lent to the user together.

  The acceleration sensor 16 detects the acceleration of the mobile device 10 </ b> C and outputs the detection result to the control unit 13.

(Article side device 30C)
The article-side device 30C is provided on a glass 80 used at a party venue, as shown in FIG. In the present embodiment, it is assumed that the article-side device 30C is provided in all the glasses 80 used in the party venue. As illustrated in FIGS. 10 and 11A, the article-side device 30C includes a storage unit 31, a communication unit 32, a control unit 33, an acceleration sensor 35, and a display unit 36.

  The storage unit 31 is a nonvolatile semiconductor memory such as a flash memory, for example, and stores information (ID number) received from the mobile device 10C for recognizing the mobile device 10C.

  The communication unit 32 communicates with other devices. For example, proximity communication such as Bluetooth (registered trademark), Felica (registered trademark), RFID, or human body communication via a user can be used. In the present embodiment, the communication unit 32 performs human body communication using the electrode part 321 provided on a part of the glass 80 (the outer peripheral surface (see FIG. 11A) that the user's hand contacts) and the electrode part 321. And a human body communication unit 322 to perform. The human body communication unit 322 communicates with the human body communication unit 112 of the mobile device 10C and receives the ID number of the mobile device 10C from the mobile device 10C. In addition, when the user is a bare hand (that is, when the electrode unit 321 is in contact with the hand), the human body is used even when wearing gloves (that is, when the electrode unit 321 is facing the hand). Communication is possible.

  The control unit 33 includes a CPU, a RAM, a ROM, and the like, and controls the entire article-side device 30C. Details of the processing executed by the control unit 33 will be described later.

  The acceleration sensor 35 detects the acceleration of the article-side device 30 </ b> B and outputs the detection result to the control unit 33. In the present embodiment, the control unit 33 and the acceleration sensor 35 are stored in an electronic component storage unit 81 located at the bottom of the glass 80 shown in FIG.

  The display unit 36 is for informing the user of the results of pairing processing and determination processing described later, and includes a blue LED and a red LED in the present embodiment. Under the control of the control unit 33, the display unit 36 turns on the blue LED or turns on the red LED.

  Next, an example of processing executed by the control unit 13 of the mobile device 10C and processing executed by the control unit 33 of the article side device 30C will be described with reference to the flowcharts of FIGS. 12 (A) and 12 (B). In the present embodiment, the process of FIG. 12A is started when a user who is a party participant turns on the power of the mobile device 10C, and the process of FIG. It starts when the power supply of is turned on.

  In the process of FIG. 12A, first, in step S201, the control unit 13 of the mobile device 10C waits until it detects a timing at which human body communication with the article-side device 30C is to be established. In the present embodiment, the control unit 13 recognizes the user's operation based on the acoustic data collected by the microphone 14 and the acceleration of the mobile device 10 </ b> C detected by the acceleration sensor 16. And the control part 13 judges that the timing which communication with 10 C of portable apparatuses and the goods side apparatus 30C should be established in when the recognized operation | movement is the operation | movement which picks up glass. For example, when the user who carries the portable device 10C and enters the party venue picks up a new glass, the control unit 13 proceeds to step S203.

  If transfering it to step S203, the control part 13 will wait until human body communication with the goods side apparatus 30C will be materialized. When human body communication with the article-side device 30C is established, the control unit 13 proceeds to step S205. If transfering it to step S205, the control part 13 will transmit the ID number of 10 C of portable apparatuses memorize | stored in the memory | storage part 12 to 30 C of goods side apparatuses, and will return to step S201.

  On the other hand, the control unit 33 of the article-side device 30C stands by until the glass is picked up based on the output of the acceleration sensor 35 in step S221 of FIG. For example, when the acceleration of the glass detected by the acceleration sensor 35 is equal to or greater than a threshold value, the control unit 33 determines that the glass has been picked up. When the user picks up the glass, the control unit 33 proceeds to step S223.

  If transfering it to step S223, the control part 33 will judge whether the human body communication was materialized between 10C of portable devices. When determination here is denied, it progresses to step S225 and the control part 13 determines whether predetermined time (for example, 10 second) passed. If the predetermined time has not elapsed, the control unit 13 returns to step S223. Here, since the party participant carries the portable device 10C, when the party participant picks up the glass 80, human body communication should be established with the portable device 10C within a predetermined time. That is, the affirmative determination in step S223 before the positive determination in step S225 means that the party participant has lifted the glass. When the determination in step S223 is affirmed and the process proceeds to step S227, the control unit 33 receives the ID number of the mobile device 10C from the mobile device 10C.

  Next, in step S229, the control unit 33 determines whether an ID number is already stored in the pairing information table stored in the storage unit 12. When determination here is denied, the control part 33 transfers to step S231. Note that the determination in step S229 is denied because the user picks up the glass 80 for the first time.

  If transfering it to step S231, the control part 33 will memorize | store the ID number of 10 C of portable apparatuses in which human body communication was materialized in the pairing information table of the memory | storage part 12. FIG. Thereby, the portable device 10C and the article-side device 30C provided on the glass 80 taken up by the user are paired. In the present embodiment, the pairing information table stores only one ID number of the mobile device 10C.

  Next, in step S233, the control unit 33 notifies the user that the pairing has been normally performed. For example, the blue LED included in the display unit 36 is turned on once. Thereby, the user can confirm that the portable device 10 </ b> C carried by the user can be paired with the glass.

  Next, a case will be described in which a user places a glass that still contains a drink on the table and picks up the glass on the table after a while. In this case, in the process of FIG. 12A, the determinations in steps S201 and S203 are affirmed. And the control part 13 of 10 C of portable apparatuses transmits ID number in step S205, and returns to step S201.

  On the other hand, the control unit 33 of the article-side device 30B executes the processes of steps S221 to S227 in the process of FIG. 12B and performs the determination of step S229. Here, someone's ID number is already stored in the pairing information table of the article-side device 30C provided on the glass 80 once used by someone. Therefore, in such a case, the determination in step S229 in FIG. 12B is affirmed, and the control unit 33 proceeds to step S235.

  In step S235, the control unit 33 determines whether the ID number received in step S227 is the ID number of the paired mobile device 10C. That is, the control unit 33 determines whether or not the ID number received in step S227 matches the ID number stored in the pairing information table.

  For example, when the glass picked up by the user is a glass used by another participant, the ID number received in step S227 does not match the ID number stored in the pairing information table. Therefore, in such a case, the determination in step S235 is denied, and in step S239, the control unit 33 notifies that the taken-up glass is not the user's glass. For example, the control unit 33 turns on the red LED included in the display unit 36 twice. Thereby, since the user can know that the glass taken up by himself / herself is not the one he / she used, it is possible to avoid a situation in which the glass used by other participants is erroneously used.

  On the other hand, when the glass picked up by the user is the glass used by the user, the ID number received in step S227 matches the ID number stored in the pairing information table. Therefore, in such a case, the determination in step S235 is affirmed, and in step S237, the control unit 33 notifies that the taken-up glass is the user's glass.

Therefore, the determination in step S223 is denied and the determination in step S225 is affirmed, so that the control unit 33 proceeds to step S241.

  If transfering it to step S241, the control part 33 will initialize the pairing information table memorize | stored in the memory | storage part 31. FIG. That is, the control unit 33 deletes the ID number stored in the pairing information table and empties the pairing information table. This makes it possible to store a new ID number in the pairing information table when using a new glass that has been cleaned and cleaned by the waiter. In step S241, the control unit 33 may notify the waiter that the pairing information table is empty, for example, by turning on the blue LED of the display unit 36 for a predetermined time.

  As described above, the article-side device 30C repeats the process in FIG. 12B until the power is turned off.

  As described above in detail, according to the third embodiment, the article-side device 30C provided on the glass 80 communicates with the communication unit 32 that communicates with the portable device 10C by human body communication via the user. When the control unit 33 that detects the timing at which communication between the unit 32 and the portable device 10C should be established, and when the control unit 13 detects the timing, the user is determined based on the communication state between the communication unit 32 and the portable device 10C. The display unit 36 that notifies whether or not the article-side device 30C included in the taken-up glass is the article-side device 30C paired with the portable device 10C. As described above, the glass held (taken up) by the user is paired with the portable device 10C at an appropriate timing at which communication between the communication unit 32 and the article-side device 30C provided in the glass 80 should be established. Since it is notified whether it is a glass, when selecting the glass which oneself used from many glasses, the situation which mistakes the glass which others used can be prevented.
