Alternatively, for example, the processor 41 changes the color of a part or all of the area in which the product to be purchased is displayed to be in the purchased state. The release button B22 is a button operated by the operator of the user terminal 40 when deselecting the product to be purchased in the selected state because the product shown in the character string S21 is not taken from the display location. be. When the release button B22 is operated, the selection of the product to be purchased in the selected state is canceled. The state of the product to be purchased that is not in the purchased state is referred to as the "unpurchased state". A product to be purchased that has not been purchased is in a state in which it can be seen that the product has not been acquired or has not been purchased.
Note that FIG. 20 is a selected screen SC2 when a product in an unpurchased state is selected. The selected screen when the purchased state is selected includes the character string S22 instead of the character string S21, and includes the cancel button B23 instead of the check button B21. The character string S22 includes a character string asking whether or not the selected product to be purchased has been returned to the display location, or a character string asking whether the product to be purchased may be left unpurchased. The cancel button B23 is a button operated by the operator of the user terminal 40 when the product to be purchased indicated by the character string S21 is in the unpurchased state.

In Act 56, the processor 41 determines whether or not an operation of deselecting the product to be purchased in the selected state has been performed. That is, the processor 41 determines whether or not a predetermined operation such as operating the release button B22 has been performed. If the operation of deselecting the product to be purchased in the selected state is not performed, the processor 41 determines No in Act56 and proceeds to Act57.

In Act 57, the processor 41 determines whether or not an operation has been performed to put the product to be purchased into the purchased state. That is, the processor 41 determines whether or not a predetermined operation such as operating the check button B21 has been performed. If the operation to put the product to be purchased into the purchased state is not performed, the processor 41 determines No in Act 57 and proceeds to Act 58.

In Act 58, the processor 41 determines whether or not an operation has been performed to put the product to be purchased into an unpurchased state. That is, the processor 41 determines whether or not a predetermined operation such as operating the cancel button B23 has been performed. If the operation to put the product to be purchased into the unpurchased state is not performed, the processor 41 determines No in Act 58 and returns to Act 56. Thus, the processor 41 repeats Act56 to Act58 until an operation of deselecting the product to be purchased in the selected state, an operation of making the product to be purchased into the purchased state, or an operation of making the product to be purchased into the unpurchased state is performed. ..
If the operation of canceling the selection of the product to be purchased in the selected state is performed while the processor 41 is in the standby state of Act56 to Act58, the processor 41 determines Yes in Act56 and proceeds to Act63.

On the other hand, if the operation to put the product to be purchased into the purchased state is performed while the processor 41 is in the standby state of Act56 to Act58, the processor 41 determines Yes in Act57 and proceeds to Act59.
In Act 59, the processor 41 generates a check request for instructing the product to be purchased to be in the purchased state. The check request includes a shopping target list ID, a purchase schedule ID of the selected product to be purchased, and a member ID stored in the RAM 43 or the auxiliary storage device 44. Then, the processor 41 instructs the communication interface 45 to send the generated check request to the support server 10. In response to this instruction, the communication interface 45 transmits the check request to the support server 10. The transmitted check request is received by the communication interface 15 of the support server 10.

On the other hand, in Act221 of FIG. 16, the processor 11 of the support server 10 determines whether or not the check request has been received by the communication interface 15. If the check request has not been received by the communication interface 15, the processor 11 determines No in Act221 and proceeds to Act222.

In Act222, the processor 11 determines whether or not a cancellation request has been received by the communication interface 15. The cancellation request will be described later. If the cancellation request has not been received by the communication interface 15, the processor 11 determines No in Act222 and proceeds to Act223.

In Act223, the processor 11 determines whether or not the purchase request has been received by the communication interface 15. The purchase request will be described later. If the purchase request has not been received by the communication interface 15, the processor 11 determines No in Act223 and proceeds to Act224.

In Act 224, the processor 11 determines whether or not a second termination request has been received by the communication interface 15. The second termination request will be described later. If the second termination request has not been received by the communication interface 15, the processor 11 determines No in Act 224 and proceeds to Act 225.

In Act 225, the processor 11 determines whether or not a payment request has been received by the communication interface 15. The settlement request will be described later. If the payment request has not been received by the communication interface 15, the processor 11 determines No in Act225 and returns to Act221. Thus, the processor 11 repeats Act221 to Act225 until a check request, a cancellation request, a purchase request, a second termination request, or a settlement request is received.

If the check request is received while the processor 11 is in the standby state of Act221 to Act225, the processor 11 determines Yes in Act221 and proceeds to Act226. In Act226, the processor 11 sets the purchase flag associated with the purchase schedule ID in the registration table T3 in order to put the purchase schedule product specified by the purchase schedule ID included in the check request received in Act221 into the purchased state. Set the value to True. Further, the processor 11 substitutes the current time into the purchase date and time associated with the purchase schedule ID in the registration table T3.

Further, if the processor 41 of the user terminal 40 performs an operation to put the product to be purchased into the unpurchased state while in the standby state of Act56 to Act58 in FIG. 12, it is determined as Yes in Act58 and the process goes to Act60. And proceed.

In Act 60, the processor 41 generates a cancellation request for instructing the product to be purchased to be in the unpurchased state. The cancellation request includes a shopping target list ID, a purchase schedule ID of the selected product to be purchased, and a member ID stored in the RAM 43 or the auxiliary storage device 44. Then, the processor 41 instructs the communication interface 45 to send the generated cancellation request to the support server 10. In response to this instruction, the communication interface 45 sends the cancellation request to the support server 10. The transmitted cancellation request is received by the communication interface 15 of the support server 10.

On the other hand, if the cancellation request is received while in the standby state of Act221 to Act225 of FIG. 16, the processor 11 determines Yes in Act222 and proceeds to Act227.
In Act 227, the processor 11 sets the purchase flag associated with the planned purchase ID in the registration table T3 in order to make the planned purchase product specified by the planned purchase ID included in the cancellation request received in Act 222 unpurchased. Set the value to False.

The processor 11 proceeds to Act228 after processing Act226 or Act227.
In Act228, the processor 11 estimates the current position of the operator of the user terminal 40. It is considered that the operator of the user terminal 40 is in the vicinity of the display place of the product to be purchased which has been purchased or has not been purchased. Therefore, the processor 11 estimates the current position of the operator of the user terminal 40, for example, by specifying the display location of the product to be purchased that has been purchased or has not been purchased. For this purpose, the processor 11 refers to the registration table T3 and acquires the product ID associated with the purchase schedule ID included in the check request received by Act221 or the cancellation request received by Act222. Then, the processor 11 refers to the display location table T4 and acquires the display location ID associated with the product ID. By the above processing, the display place of the product to be purchased that has been purchased or has not been purchased is specified.

In Act 229, the processor 11 refers to the registration table T3, and among the purchase schedule IDs associated with the shopping target list ID included in the check request or cancellation request received in Act221 or Act222, the value of the purchase flag is False. Extract something and list it. The list is hereinafter referred to as "acquisition list".

In Act230, the processor 11 determines whether or not there is an unselected purchase schedule ID in the acquisition list. If there is an unselected purchase schedule ID in the acquisition list, the processor 11 determines Yes in Act230 and proceeds to Act231.

In Act231, the processor 11 selects one unselected purchase schedule ID from the acquisition list. The processor 11 updates the acquisition list so that it can be seen that the purchase schedule ID selected here is not unselected.

In Act232, the processor 11 refers to the registration table T3 and the display location table T4 based on the purchase schedule ID selected in Act231, and acquires the display location ID of the product to be purchased specified by the purchase schedule ID.

In Act233, the processor 11 estimates the distance from the current position of the operator of the user terminal 40 to the display place of the planned purchase product specified by the planned purchase ID selected in Act231. For this purpose, the processor 11 acquires the distance between the display place specified by the display place ID acquired by Act228 and the display place specified by the display place ID acquired by Act232. That is, the processor 11 obtains the distance by referring to the distance table T5 based on the two display place IDs. The processor 11 stores the acquired distance in the acquisition list in association with the purchase schedule ID selected in Act231. The processor 11 returns to Act230 after processing Act233. By performing the processing of Act233, the computer centered on the processor 11 functions as an acquisition unit that acquires an estimated distance from the user's current position to the display location of the product included in the shopping list.

By the above processing, the distance from the display place acquired by Act228 is acquired for each display location of the product to be purchased indicated by the purchase schedule ID in the acquisition list. If the distance is acquired for all the planned purchase IDs in the acquisition list, there will be no unselected purchase planned IDs in the acquisition list.
If there is no unselected purchase schedule ID in the acquisition list, the processor 11 determines No in Act230 and proceeds to Act234.

In Act234, the processor 11 sorts the shopping list specified by the shopping target list ID included in the check request or cancellation request received in Act221 or Act222. For this purpose, the processor 11 rewrites the registration table T3 as follows, for example. That is, the processor 11 sets the values in the display order of the purchase schedule IDs to which the shopping target list ID is associated, which are included in the acquisition list, in the order of the shortest distance associated with the acquisition list. , ... Then, when there is a purchase schedule ID associated with the shopping target list ID whose display order is 1, the processor 11 sets the value in the display order of the purchase schedule ID (the purchase schedule included in the acquisition list). Set the number of IDs + 2). Further, the processor 11 sets the value in the display order associated with the purchase schedule ID included in the check request or cancellation request received by Act221 or Act222 to 1. By the above processing, the display order is the purchase of the purchased products excluding the most recently purchased or unpurchased products, the unpurchased products, and the most recently purchased products. It will be in the order of planned products. In addition, regarding the display order of the products to be purchased in the unpurchased state, the distance from each display place to the display place of the products to be purchased in the most recently purchased or unpurchased state is the closest. The display order of the products to be purchased in the purchased state, excluding the ones that have been purchased most recently, is in the order of the latest purchase date and time. By performing the above processing, the computer centered on the processor 11 functions as a control unit that generates a list in which a plurality of products included in the shopping list are arranged in the order of estimated distances.

In Act235, the processor 11 indicates that the purchase planned product specified by the purchase schedule ID included in the check request or cancellation request received by Act221 or Act222 has been completed in the purchased state or the non-purchased state. Generate a completion notification for. The second completion notice includes the shopping list specified by the shopping target list ID included in the check request or cancellation request received by Act221 or Act222. Then, the processor 11 instructs the communication interface 15 to transmit the generated second completion notification to the user terminal 40. In response to this instruction, the communication interface 15 transmits the second completion notification to the user terminal 40. The transmitted second completion notification is received by the communication interface 45 of the user terminal 40.
The processor 11 returns to Act 224 after processing Act 235.

Hereinafter, two types of (1) and (2) will be described for estimating the display location distance.
(1) Estimating method 1
For example, consider a case where apples, grapes, green onions, peppers, pork roses, and so on are already purchased in the order of a certain shopping list. For apples and green onions, apples and peppers, and apples and pork roses, it is considered that the display location distance is longer than that of apples and grapes purchased in succession. The interval between purchases of apples and grapes is 1, the interval between purchases of apples and green onions is 2, the interval between purchases of apples and peppers is 3, the interval between purchases of apples and pig roses is 4, ..., the interval between purchases of grapes and green onions is 1. , ..., can be specified as. That is, the purchase interval is the difference between the purchase order of the two products. From the above, the distance between the display locations of the two products and the display locations can be estimated using the purchase interval as described above. For example, the processor 11 obtains the average value or the median value of the purchase interval from a plurality of shopping lists stored in the list DB for each display location distance. Then, the processor 11 stores the obtained value as the display location distance in the distance table T5.
(2) Estimating method 2
In the estimation method 2, the purchase interval is used as in the estimation method 1. However, in the estimation method 2, the difference between the purchase dates and times is used as the purchase interval. For example, the purchase date and time of apples is 16:00, the purchase date and time of grapes is 16:01, the purchase date and time of green peppers is 16:05, the purchase date and time of peppers is 16:06, and the purchase date and time of pork roses is 16:00. 10 minutes, ... In this case, the interval between purchasing apples and grapes is 1 minute, the interval between purchasing apples and green onions is 5 minutes, the interval between purchasing apples and peppers is 6 minutes, the interval between purchasing apples and pork roses is 10 minutes, and so on. The purchase interval is 4 minutes, and so on. For example, the processor 11 obtains the average value or the median value of the purchase interval from a plurality of shopping lists stored in the list DB for each display location distance, as in the estimation method 1. Then, the processor 11 stores the obtained value as the display location distance in the distance table T5. It should be noted that the larger the difference in the order of purchase, the more various routes the operator of the user terminal 40 takes during that time, so it is possible that the correlation with the display location distance becomes lower. Therefore, the processor 11 may determine the display location distance using only combinations in which the difference in the order of purchase is constant or less. For example, the processor 11 may determine the display location distance using only a combination having a difference of 1 in the order of purchase.

The processor 11 estimates the display location distance as described above on a regular or irregular basis. The processor 11 estimates the display location distance in a time zone in which computational resources are left, such as at night. The above purchase interval is an example of the interval between when the first product is in the second state and when the second product is in the second state.
