Only the transaction terminal device (refrigerator 100) listed as conforming to the transaction conditions with 100) may be a distance calculation target with respect to the one transaction terminal device (refrigerator 100).

  Alternatively, the search unit 410 may be selected from the other transaction terminal devices (refrigerator 100) whose distance from the one transaction terminal device (refrigerator 100) calculated by the distance calculation unit 420 is closer than a predetermined reference. The transaction terminal device (refrigerator 100) that matches the transaction conditions of the one transaction terminal device (refrigerator 100) may be searched. At this time, it is desirable that the reference of the distance from the one transaction terminal device (refrigerator 100) to be searched can be appropriately reset by the user.

  The negotiation unit 430 makes an article exchange negotiation between the one transaction terminal device (refrigerator 100) and another transaction terminal device (refrigerator 100). The negotiation unit 430 first determines a negotiation partner of the one transaction terminal device (the refrigerator 100). The negotiation partner is selected from the other transaction terminal devices (refrigerator 100) listed by the search unit 410 as being compatible with the transaction conditions with the one transaction terminal device (refrigerator 100).

  If no other transaction terminal device (refrigerator 100) that meets the transaction conditions with the one transaction terminal device (refrigerator 100) is found, the negotiation unit 430 does not start negotiation. When the search unit 410 finds only one other transaction terminal device (refrigerator 100) that matches the transaction condition with the one transaction terminal device (refrigerator 100), the negotiation unit 430 Determines the other transaction terminal device (refrigerator 100) as a negotiating partner of the one transaction terminal device (refrigerator 100).

  In addition, a plurality of transaction terminal devices (refrigerators 100) are listed by the search unit 410 as other transaction terminal devices (refrigerator 100) that meet the transaction conditions with the one transaction terminal device (refrigerator 100). In this case, the negotiation unit 430 selects a negotiation partner with the one transaction terminal device (refrigerator 100) from among the plurality of transaction terminal devices (refrigerator 100) listed.

  At this time, the negotiation unit 430 is a distance from the other transaction terminal device (refrigerator 100) searched by the search unit 410 to the one transaction terminal device (refrigerator 100) calculated by the distance calculation unit 420. Priority is given to the transaction terminal device (refrigerator 100) close | similar, and it selects as a negotiation object with said one transaction terminal device (refrigerator 100). That is, the negotiation unit 430 selects, as a negotiating partner, the closest one to the one transaction terminal device (refrigerator 100) from among the plurality of listed transaction terminal devices (refrigerator 100).

  As described above, the negotiation unit 430 determines two transaction terminal devices (refrigerator 100) including the one transaction terminal device (refrigerator 100) as negotiation targets. When the negotiation target is determined and the negotiation can be started, the negotiation unit 430 notifies the negotiation target to both parties via the display operation unit 110.

  Next, the negotiation unit 430 displays each other's transaction conditions on the display means of the display operation unit 110 of the one transaction terminal device (refrigerator 100) and the other transaction terminal device (refrigerator 100) determined as negotiation targets. Let And it confirms whether it agrees with transaction with respect to each terminal device (refrigerator 100) used as negotiation object.

  If the agreement of both of the transaction terminal devices (refrigerator 100) that is a negotiation target is obtained, the negotiation unit 430 establishes a negotiation between these negotiation targets. On the other hand, when the consent cannot be obtained from one or both of the transaction terminal devices (refrigerator 100) that are the negotiation targets, the negotiation unit 430 determines that the negotiation between these negotiation targets is not established. The user of each transaction terminal device (refrigerator 100) can input an intention of whether or not to agree to the transaction, for example, using the input means of the display operation unit 110.

  When the negotiation between the negotiation targets is established, the negotiation unit 430 is necessary for the next transaction such as each other's address in the display operation unit 110 of both of the transaction terminal devices (refrigerator 100) being the negotiation target. Display information.

  On the other hand, if the negotiation between the negotiation targets is not established, and there is no other transaction terminal device (refrigerator 100) listed as matching the transaction conditions by the search unit 410, the negotiation unit 430 negotiates there. Stop. In addition, when there is a transaction terminal device (refrigerator 100) listed by the search unit 410 as conforming to the transaction condition, the transaction terminal device that conforms to the transaction condition and has not yet been selected as a negotiation target Among the (refrigerator 100), the one with the shortest distance to the one transaction terminal device (refrigerator 100) is selected as a negotiation partner, and the negotiation is continued.

  In this way, the negotiation unit 430 uses the one transaction terminal device (refrigerator 100) for the other transaction terminal device (refrigerator 100) that matches the transaction conditions of the one transaction terminal device (refrigerator 100). Negotiations are made by selecting the items to be negotiated in ascending order. It should be noted that the subsequent negotiation may not be performed when the negotiation is not established more than a predetermined number of times. Further, when a cancellation message is input from one of the negotiation targets via the display operation unit 110, the negotiation may be canceled even during the negotiation.

  The market price acquisition part 440 with which the server apparatus 400 is provided acquires the market price of the goods which can be provided registered from each terminal device for transaction (refrigerator 100). The market price acquisition unit 440 searches for and acquires information related to the market price of the goods that can be provided via the Internet 300, for example. Alternatively, the user inputs the purchase price of the article that can be provided from the display operation unit 110 of the refrigerator 100, and the market price acquisition unit 440 uses the input purchase price as a reference value for the market price of the article that can be provided. May be. The market price of the available goods acquired by the market price acquisition unit 440 is stored in the product price information storage unit 504 for each type of available goods.

  The negotiation unit 430 uses the market price of the available goods acquired by the market price acquisition unit 440 in the process of negotiating the transactions between the negotiation targets so as to assist the negotiation smoothly and evenly. Also good.

  That is, first, the negotiation unit 430 calculates the total price of the items that can be provided between the negotiation targets based on the market price acquired by the market price acquisition unit 440. The total price of the items that can be provided can be calculated by multiplying the unit price of the market price of each item that can be provided by the quantity. When there are multiple types of deliverable items, calculate the product of unit price and quantity for each type of deliverable item, and then calculate the sum of the types of deliverable items for these products. be able to.

  Next, the negotiation unit 430 compares the calculated total prices of the items that can be provided between the negotiation targets. Then, in this comparison, the negotiation unit 430 first confirms whether or not to agree to the transaction for the negotiation target with the higher total price. If the total price of goods that can be provided is higher than that of the other party, if this transaction is carried out as it is, the price will be damaged. Therefore, it is possible to proceed with subsequent transaction negotiations more smoothly by confirming in advance whether or not the person who will suffer the loss agrees with the transaction.

  Further, the negotiation unit 430 may calculate the quantity of deliverable articles in which the total price of the offerable articles among the negotiation targets is equal based on the market price acquired by the market price acquisition unit 440. This is particularly effective when the negotiating object whose total price of the goods that can be provided is higher than the partner does not agree to the transaction.

  First, the negotiation unit 430 calculates the difference in the total price of the items that can be provided between the calculated negotiation targets. And the negotiation part 430 calculates the quantity of the offerable articles | goods of each negotiation object which can make the total price of the offerable articles | goods equal by filling this difference.

  In general, it is easy to reduce the number of items that can be provided, but it is considered that it is often not easy to increase the number of items that can be provided because it is necessary to procure a new item. Therefore, the following may be performed. That is, the negotiation unit 430 first calculates a quantity that can make the total price of the providable articles between the negotiation targets equal in the direction of reducing the quantity of the higher total price of the providable articles. Then, if a fraction appears in the quantity that can make the total price equal, the negotiation unit 430 rounds off the fraction and newly calculates the quantity of the deliverable item whose total price is higher than the partner. cure.

  Further, if there is an article that is not yet registered as a desired article in the list of articles that can be provided by the negotiation partner, the article may be newly registered as the desired article here. When a desired article is added from a higher total offerable article price, the negotiation unit 430 recalculates the total price of the offerable articles among the negotiation targets in consideration of the added desired article.

  It should be noted that the total price and the difference between the negotiable items calculated by the negotiation unit 430 are displayed on the display operation unit 110 of each negotiation target. In this way, the negotiation unit 430 presents information such as the quantity that makes the total price of the articles that can be provided between the negotiation targets equal to the negotiation target based on the market price acquired by the market price acquisition unit 440. Transaction negotiations can be promoted more smoothly and evenly.

  The server device 400 having the functional configuration as described above can be implemented using, for example, a known computer. An example of a hardware configuration for mounting the server device 400 will be described next with reference to FIG.

  The server device 400 includes a CPU 601, a ROM 602, a RAM 603, and a communication interface 604. The CPU 601 is a central processing unit that executes a given instruction (including a program that is a set of instructions) to perform calculation or processing of information. The ROM 602 is a read only memory that stores data or programs in a nonvolatile manner. The RAM 603 is a readable / writable random access memory (Random Access Memory) for storing data or programs in a volatile manner, that is, temporarily.

  The communication interface 604 is hardware necessary for the server apparatus 400 to communicate with the outside. Here, the server apparatus 400 is connected to the Internet 300 which is a communication network via a communication interface 604. The CPU 601, ROM 602, RAM 603, and communication interface 604 are connected to each other via a bus so that information can be exchanged between them.

  The server device 400 may include a hard disk, a CD-ROM, or the like as an external storage device, or may include a display output unit (for example, a monitor), an input unit (for example, a keyboard), or the like.

  The ROM 602 of the computer constituting the server device 400 stores in advance a program for operating the computer configured as described above as the server device 400. The CPU 601 first reads the program from the ROM 602 and stores the program in an executable format in the RAM 603. Then, the CPU 601 executes the program stored in the RAM 603 while reading it.

  In this way, when the software program is read into the computer, the calculation or processing of the information is realized by specific means in which the software and the hardware resources cooperate, as described above. A server apparatus 400 having the functions shown in FIG. 1 is constructed. That is, the program executed by the CPU 601 of the computer of the server device 400 is for causing the computer of the server device 400 to function as each unit of the search unit 410, the distance calculation unit 420, the negotiation unit 430, and the market price acquisition unit 440. It is.

  The program may be stored not in the ROM 602 but in an external storage device, or the program may be downloaded from the outside to a computer via the communication interface 604 and used.

  Further, the display terminal unit 110 for transaction, the entire transaction terminal device, and the mobile terminal 200 can also be configured by hardware using a well-known computer, similar to the server device 400. is there.

  Next, the overall flow of the negotiation process of the transaction support system configured as described above will be described with reference to FIG. First, in step S1, the position information acquisition unit 120 of each transaction terminal device (refrigerator 100) acquires the installation position information of the transaction terminal device (refrigerator 100). The acquired installation position information is sent to the server device 400 via the Internet 300 and stored in the address information storage unit 502.

  In the subsequent step S2, the offerable articles to be exchanged are registered by the provided article registration means of each transaction terminal device (refrigerator 100). Here, the articles stored in the specific storage compartment in the refrigerator 100 are detected and registered as articles that can be provided by the extraction means of the camera 106 and the display operation unit 110. The registered information about the provided items is sent to the server device 400 via the Internet 300 and stored in the provided item information storage unit 501.

  In subsequent step S3, the desired article to be exchanged is registered by the desired article registration means of each transaction terminal device (refrigerator 100). Here, the desired article is registered based on the information input by the input means of the display operation unit 110. The registered information on the desired article is sent to the server device 400 via the Internet 300 and stored in the desired article information storage unit 503.

  In the subsequent step S4, the server apparatus 400 checks whether or not there is another user who uses an article that one user desires to exchange as an article to be exchanged. That is, in other words, the search unit 410 of the server device 400 uses the information stored in the provided product information storage unit 501 and the desired product information storage unit 503 from a certain transaction terminal device (refrigerator 100). The other transaction terminal device (refrigerator 100) different from the one transaction terminal device (refrigerator 100) in which the same offerable item as the registered desired item is registered is searched.

  In this step S4, with the one transaction terminal device (refrigerator 100) in which the searchable unit 410 has registered the same offerable item as the desired item registered from one transaction terminal device (refrigerator 100). When it is not possible to find another different transaction terminal device (refrigerator 100), that is, when there is no other user as an article to be exchanged for an article desired by a certain user. In this case, a series of processing ends.

  On the other hand, in step S4, the one transaction terminal device (refrigerator 100) that registers the same offerable item as the desired item registered from one transaction terminal device (refrigerator 100) with the search unit 410. If a different transaction terminal device (refrigerator 100) is found, that is, if there is another user who uses an article that one user wants to exchange as an article to be exchanged, step S5 Proceed to

  In step S5, the server apparatus 400 exchanges and provides the one user among the other users who are the articles to be exchanged and provided by the one user confirmed in step S4. It is confirmed whether or not there is another user who makes the article as an article desired to be exchanged. That is, in other words, the search unit 410 of the server device 400 uses the information stored in the provided article information storage unit 501 and the desired article information storage unit 503 among the other users searched in step S4. Then, another transaction terminal device (refrigerator 100) in which the same desired article as the available item registered from the one transaction terminal device (refrigerator 100) is registered is searched.

  In step S5, the search unit 410 registers the same desired article as the available article registered from the one transaction terminal device (refrigerator 100) among the other users searched in step S4. If the other transaction terminal device (refrigerator 100) is not found, that is, among other users who are exchanged articles provided by one user confirmed in step S4. When there is no other user who uses the article to be exchanged and provided by the one user as an article desired to be exchanged, the series of processing ends.

  On the other hand, in step S5, the search unit 410 registers, among the other users searched in step S4, the same desired item as the available item registered from the one transaction terminal device (refrigerator 100). When the other transaction terminal device (refrigerator 100) is found, that is, among other users who are exchanged articles provided by one user confirmed in step S4. If there is another user who uses the article to be exchanged and provided by the one user as an article to be exchanged, the process proceeds to step S6.

  In step S6, the negotiation unit 430, based on the distance calculated by the distance calculation unit 420, out of the one user confirmed in step S5 and the other user whose transaction conditions match, Negotiate in the order of close proximity to users.

  Then, the process proceeds to step S7, and if the negotiation in step S6 is established, the series of processes is ended. On the other hand, if the negotiation in step S6 is not successful, the process returns to step S5 and negotiates until there are no users to be negotiated.

  Note that, as described above, the search unit 410 has another transaction terminal device (refrigerator) whose distance from the one transaction terminal device (refrigerator 100) calculated by the distance calculation unit 420 is closer than a predetermined reference. 100), the transaction terminal device (refrigerator 100) that matches the transaction conditions of the one transaction terminal device (refrigerator 100) may be searched. In this case, it is desirable that the reference of the distance from the one transaction terminal device (refrigerator 100) to be searched can be appropriately reset by the user.

  Therefore, as a modification of the flow of FIG. 6, as shown in FIG. 7, the process of step S0 may be added between step S3 and step S4. In this added step S0, the user registers the distance reference to be searched by the search unit 410 in step S4 using the input means of the display operation unit 110 of the transaction terminal device (refrigerator 100). To do. In step S4, another transaction terminal device (refrigerator 100) that matches the transaction conditions is searched within a range closer to the distance reference registered in step S0.

  Next, details of the processing from step S6 to step S7 in the flowcharts of FIGS. 6 and 7 will be described with reference to FIGS. First, FIG. 8 shows a first example of processing related to negotiation mediation in steps S6 to S7. In FIG. 8, first, in step S8, the negotiation unit 430 determines the market price of the article to be exchanged with one of the negotiation-provided articles based on the market price of the article acquired by the market price acquisition unit 440. calculate.

  Next, the process proceeds to step S9, and the difference in market price that occurs when the quantity of articles exchangeable between negotiation targets is exchanged is calculated. In addition, since attention is paid when the quantity of exchangeable goods is exchanged, the market price of the goods that one negotiation object desires to exchange is equal to the market price of the goods exchanged and provided by the other negotiation object.

  Then, the process proceeds to step S10, and the negotiation unit 430 confirms whether or not to agree to the transaction for the negotiating object that loses by the difference between the market prices calculated in step S9. When the negotiating object of the person who suffers the loss agrees to the transaction, the process proceeds to step S11.

  In step S <b> 11, the negotiation unit 430 confirms whether or not to agree to the transaction with respect to the negotiation target that is obtained by the difference between the market prices calculated in step S <b> 9. If the negotiating object of the winning party also agrees with the transaction, the process proceeds to step S12.

  In step S <b> 12, the negotiation unit 430 determines that the negotiation target is agreed and the negotiation is established. When the negotiation is established in this way, the series of processing ends.

  On the other hand, in step S10, when the negotiating subject who loses does not agree to the transaction, the process proceeds to step S13. In step S13, the negotiation unit 430 exchanges an article provided by the negotiating partner of the negotiating partner (that is, the negotiating target of the profitable party) that is subject to the loss with the article desired by the negotiating target of the suffering party. Check if it exists. If there is an article that the negotiating target of the person suffering the loss desires, the process proceeds to step S14.

  In step S <b> 14, the negotiation unit 430 inputs the desired article and quantity via the display operation unit 110 to the negotiating target who suffers the loss. When the desired article and quantity are input, based on this input information, the negotiation unit 430 recalculates the difference in the market price of the traded article.

  After step S14, the process proceeds to step S15. In addition, if the article desired by the negotiating party to be damaged in step S13 is not in the article provided by exchange of the negotiation partner, the process proceeds to step S15 without passing through step S14.

  In step S <b> 15, the negotiation unit 430 determines whether or not to reduce the quantity of articles exchanged and provided to the other party from the negotiating target that suffers loss. This determination may be made based on the difference between the market prices of both negotiation targets calculated by the negotiation unit 430, or may be determined based on the contents entered by the negotiation target that loses the display operation unit 110. And when reducing the quantity of the articles | goods exchange-provided to the other party from the negotiating object of the person who loses, it progresses to step S16.

  In step S <b> 16, the negotiation unit 430 recalculates the difference in the market price of the traded goods after reducing the quantity of the goods exchanged and provided to the other party from the negotiating target. After step S16, the process proceeds to step S17. If the quantity of articles exchanged and provided to the other party is not reduced from the subject of negotiation in step S15, the process proceeds to step S17 without passing through step S16.

  In step S17, the negotiation unit 430 agrees with the transaction whose conditions have been changed through steps S13 to S16 with respect to the negotiation target who loses the difference of the market price calculated in step S9. Check again. If the negotiating subject who loses the market price difference calculated in step S9 agrees to the transaction, the process proceeds to step S11.

  On the other hand, in step S17, if the negotiating subject who loses by the difference between the market prices calculated in step S9 does not agree with the transaction, the negotiation is not established and the series of processes ends. In addition, even when the bargaining target that is obtained in step S11 does not agree with the transaction, the bargaining is not established, and the series of processes ends.

  Next, FIG. 9 shows a second example of processing relating to negotiation mediation in steps S6 to S7 in FIGS. The contents of each step from step S8 to step S17 in FIG. 9 are the same as the steps having the same reference numerals in FIG. Therefore, the description of the contents of the individual steps is redundant and will be omitted. However, the second example shown in FIG. 9 differs from the first example in FIG. 8 in the transition destination of the conditional branch in step S17.

  That is, the second example shown in FIG. 9 returns to step S10 when the negotiating subject who loses the difference of the market price calculated in step S9 agrees to the transaction in step S17 ( On the other hand, in the first example of FIG. 8, the process proceeds to step S11). As a result of changing the transaction conditions from step S13 to step S16, there may be a case where the position of loss between the negotiation targets is reversed.

  Therefore, in this second example, the person who loses and the person who gains are identified again with the latest market price recalculated in step S14 or step S16. And it returns to step S10 and the negotiation part 430 confirms consent from the side which suffers loss with the newest market price recalculated first.

  In the above description, the example in which the transaction terminal device includes the refrigerator 100 has been described. However, the transaction terminal device does not necessarily include the refrigerator 100. If it is possible to register an article that can be provided, it is sufficient to provide a case that does not have a refrigeration function, or it is sufficient to provide a camera that photographs the article that can be provided. Further, the image captured by the camera 106 as the image capturing unit may be a still image or a moving image.

  According to the transaction support system configured as described above, an unnecessary article and a desired article can be exchanged, and an article that has been discarded so far, for example, an article in a refrigerator can be effectively used and a necessary article can be used. Will be able to obtain. In addition, taking into consideration the physical distance between the negotiation objects, it is possible to reduce the cost, time, or labor required when actually exchanging goods. That is, since a negotiation partner is preferentially selected from nearby items, it is economical in terms of time and transportation costs. Furthermore, since the exchange can be performed in consideration of the market price of the goods, equality among the users of the system is maintained.
