Alternatively, the server 10 may set the product identification code itself as the product ID.
Further, the server 10 may uniquely set product IDs for all products regardless of whether or not the products have product identification codes.

Also, the product price management data may store the average price of the product in all stores during a past set period (for example, the past one month period).
Also, the store-by-store product price data may store the history of the product price of the product at the store. Similarly, the average price of the product at the store during the past set period (as an example, not limited to the period of the past one month) may be stored.
In addition, the bargain sale information of the store may be stored in the store-by-store product price data in association with the product ID.

The receipt information management database 157 is a database for managing receipt information, and an example of its data structure is shown in FIG. 1-7.
The receipt information management database 157 stores receipt information management data as management data of receipt information for each receipt.

Here, the receipt information can include, by way of example and not limitation, at least one of the following.
(A1) When the user of the terminal 20 manually inputs with reference to the receipt: Store name, receipt issue date, product name, product unit price, number of products, product weight (number of grams, etc.), product identification code, total amount, etc. ( A2) When a receipt is photographed by the terminal 20: The receipt image itself, or digitized information/data (text information/text data, etc.) obtained by performing OCR (Optical Character Recognition/Reader) on the receipt image on the terminal 20. , various information of (A1) specified from these information, etc.

Note that these terminals 20 do not necessarily include the terminal 20A. That is, user A. of terminal 20A. It is not essential for A to participate in tallying receipt information.

First, the control unit 21 of the terminal 20A receives input of receipt information by the user via the input/output unit 23 as an example and not limitation (A105). Specifically, as an example and not as a limitation, the user can be made to input various types of information shown in (A1) described above as receipt information.

After that, the control unit 21 of the terminal 20A transmits the receipt information input by the user via the input/output unit 23 to the server 10 via the communication I/F 22 (A120).

When receipt information is received from the terminal 20A through the communication I/F 14, the control unit 11 of the server 10 performs receipt information analysis processing (S110). Specifically, the terminal 20 that received the receipt information or the application ID of its user is used as the registrant application ID, and based on the received receipt information, the receipt ID, the date and time of issue of the receipt, the ID of the store issuing the receipt, and the receipt details data. The receipt information management data including the receipt information management data is generated and added to the receipt information management database 157 .

In this case, the control unit 11 of the server 10, as a non-limiting example, based on the product name included in the receipt information, if the product price management data of the same product name has already been registered in the product price management database 155A, By estimating that the product ID is the same as the registered product ID, the product ID can be stored in the receipt detail data.

Note that in step S110, the control unit 11 of the server 10 determines the specified unit price per gram (not limited to, but an example , the price per "100 grams") may be estimated and stored in the product unit price of the receipt detail data.

Next, the control unit 11 of the server 10 performs receipt information tallying processing (S120). Specifically, as an example and not a limitation, the control unit 11 reflects the data added to the receipt information management database 157 to generate product price management data corresponding to each product ID included in the product price management database 155A. to update.

After A120, the control unit 21 of the terminal 20A determines whether or not to end without inputting receipt information based on another receipt (A125). Return the processing to A105.
On the other hand, if it is determined to end (A125: YES), the control unit 21 of the terminal 20A transmits input end information indicating that to the server 10 via the communication I/F 22 (A135). Then, the control unit 21 of the terminal 20A terminates the process.

After S120, the control unit 11 of the server 10 determines whether or not the input end information has been received from the terminal 20A through the communication I/F 14 (S125). The process is returned to S110.
On the other hand, if it is determined that the input end information has been received (S125: YES), the control unit 11 of the server 10 ends the process.

In addition, as described above, it is also possible for the user to input the product price of a single item. When accepting the price of a single item, as a non-limiting example, in step A105, the control unit 21 of the terminal 20 selects, as a non-limiting example, the store name and , product name, and product unit price.

Instead of inputting the store name, the control unit 21 of the terminal 20A may acquire position information and transmit it to the server 10. FIG. Also, instead of inputting the product name, the barcode information of the product acquired by the imaging unit 27 may be acquired by the control unit 21 of the terminal 20A.

In this case, in the receipt information analysis process, the control unit 11 of the server 10 estimates the store ID and the product ID based on the store name and product name included in the receipt information. Then, the control unit 11 of the server 10 updates the product price management data corresponding to each product ID included in the product price management database 155A. As a non-limiting example, it is possible for the user of the terminal 20A to tally up the prices of the products found at the store one by one.

(2) Second process The second process is a process of acquiring receipt information by the terminal 20 reading the receipt. This processing corresponds to the flow of the display screen shown in FIG. 1-10.

FIG. 1-13 is a flow chart showing an example of the flow of processing executed by each device in this case. The view of the figure is the same as that of FIG. 1-11.
First, the control unit 21 of the terminal 20A performs receipt reading processing (A110). Specifically, as an example and not as a limitation, based on user input via the input/output unit 23, the imaging unit 27 is controlled to perform processing for capturing an image of a receipt.

After that, the control unit 21 of the terminal 20A transmits the receipt information to the server 10 via the communication I/F 22 (A120). In this case, the control unit 21 can transmit any of the following information to the server 10 as an example and not as a limitation.
- Captured image of the receipt captured by the imaging unit 27 (hereinafter referred to as "receipt image")
・Receipt text information acquired by OCR etc. (hereinafter referred to as “receipt text information”)

When receipt information is received from the terminal 20A through the communication I/F 14, the control unit 11 of the server 10 performs the following processing as receipt information analysis processing (S110).

When the receipt information received from the terminal 20A is a receipt image, the control unit 11 converts the receipt into text data by performing OCR or the like. Then, based on the receipt text information obtained as a result, receipt information management data including the receipt ID, receipt issue date and time, receipt issue store ID, and receipt detail data is generated in association with the registrant application ID, and the receipt information is generated. Add to management database 157 .

If the receipt information transmitted from the terminal 20A is receipt text information, the control unit 11 associates it with the registrant application ID based on the received receipt text information to generate the receipt ID, receipt issue date and time, receipt issue store ID, Receipt information management data including receipt detail data is generated and added to the receipt information management database 157 .

As described above, if the receipt information includes a product identification code, the product identification code may be used as the product ID.

After S110, the control unit 11 of the server 10 advances the process to S120.

After A120, the control unit 21 of the terminal 20A determines whether or not to finish reading the receipt (A130), and if it determines to continue reading the receipt (A130: NO), returns the process to A110.
On the other hand, if it is determined to finish reading the receipt (A130: YES), the control unit 21 of the terminal 20A transmits reading end information to the server 10 via the communication I/F 22 (A140). Then, the control unit 21 of the terminal 20A terminates the process.

After S120, the control unit 11 of the server 10 determines whether or not the reading end information has been received from the terminal 20A via the communication I/F 14 (S130). The process is returned to S110.
On the other hand, if it is determined that the reading end information has been received (S130: YES), the control section 11 of the server 10 ends the process.

(a3) Was the coupon used? As a non-limiting example, a product that can be discounted by using a coupon (as a non-limiting example, such as a product with the lowest price using a coupon as shown on the right side of Figure 3-4) is identified from the receipt information. determines whether the purchase price on the coupon matches the product price when the coupon is used.

(a1) is intended to determine this because there is a possibility that the user may forget to buy some products by mistake.

(a2) is intended to determine the possibility that the user may mistakenly purchase less than the intended number of purchases.
In addition, since there is a possibility that the user will purchase a large number of products as a spare, in this example, it is determined whether or not "the planned number of purchases≦the number of purchases".

(a3) is intended to determine the possibility that the user may purchase the product without using the coupon by mistake.

In addition to these, whether or not the store where the product was purchased is the same may be included in the above determination.

The control unit 11 of the server 10 can make at least one of the above determinations. Then, when the determination result is a negative determination, the control unit 11 of the server 10 determines that there is a possibility of forgetting to buy (detection of forgetting to buy).

When forgetting to buy is detected (S360: YES), the control unit 11 of the server 10 transmits forgetting to buy information to the terminal 20A via the communication I/F 14 (S370). Specifically, as a non-limiting example, the name of the product judged to have been forgotten to buy, information indicating that the number of purchases does not match the planned number of purchases, information indicating that the number of purchases is less than the planned number of purchases, and shortage information on the number of products purchased (planned number of purchases - number of purchases), information indicating that the coupon was not used, information such as the name of the product for which the coupon was not used, etc. Send.

After S370, or when forgetting to buy is not detected (S360: NO), the control unit 11 of the server 10 performs receipt information tallying processing (S380). This process can be the same as the step of S120.
Then, the control unit 11 of the server 10 terminates the process.

After A350, the control unit 21 of the terminal 20A determines whether or not the forget-to-buy information is received from the server 10 via the communication I/F 22 (A360). The forgot-to-buy information is displayed on the display unit 24 (A370). Then, the control unit 21 of the terminal 20A terminates the process.
If it is determined that the forget-to-buy information has not been received (A360: NO), the control unit 21 of the terminal 20A terminates the process.

It should be noted that there may be a case where the user accidentally purchases more products than the planned number of purchases, even though the user planned to purchase only the planned number of products.
Therefore, in the above (a2), when it is determined that "the number of purchases < the number of purchases", information indicating that the number of purchases does not match the number of purchases, or the number of purchases is greater than the number of purchases Information indicating the fact, information on the number of excessive purchases (number of purchases - number of planned purchases), etc. may be transmitted to the terminal 20A to notify the user of these.

This modification shows a configuration in which the target terminal 20 displays on the display unit 24 information about forgetting to buy a product or service based on shopping list information (an example of the list, not limitation) and receipt information. there is
As an example of the effect of the modified example obtained by such a configuration, it is possible to notify the user of the possibility of forgetting to buy, and to improve the user's convenience.

<Third modification (2)>
The server 10 transmits to the terminal 20 time sale information to be held at the store based on the result of analyzing and tabulating the receipt information. Then, the terminal 20 may cause the display unit 24 to display the received time sale information.

As an example and not a limitation, the control unit 11 of the server 10 refers to the receipt information management database 157 and calculates the correlation between the receipt issuing date and time and the product unit price for each receipt issuing store ID and product ID. Then, a predetermined period (a specific date (as an example, not a limitation, the first day of every month), a specific day of the week (as an example, not a limitation, Thursday), a specific time zone (as an example, not a limitation, "16:00 to 17 : 00"), etc.), the price of a specific product is significantly lower (as an example, not a limitation, the price has fallen by 2σ or more from the 7-day moving average: where σ is the standard deviation), the specified product It is possible to determine that it is a time sale period and issue time sale information.

Note that even if it is detected that the unit price of a product at a store located within a predetermined period of time (not limited to, but within 30 minutes as an example, within 30 minutes) from the current time has significantly decreased, the guerrilla sale will be held at that store. Therefore, the control unit 11 of the server 10 can issue time sale information in real time.

In addition, when time sale information is included in the receipt issued at the store where the product was purchased, provision of temporary sale information to others based on the time sale information included in the receipt information provided to the server 10 by the user himself/herself can do.

Also, in this case, the server 10 may transmit the time sale information to the terminal 20 based on the user's attribute information (eg, gender, age (age), preferences, etc.). User attribute information may be stored, by way of example and not limitation, in other registration information of account registration data 153 (FIGS. 1-4).

Specifically, as an example and not as a limitation, for male (female) users, time sale information of products likely to be purchased by male (female) users is transmitted to terminal 20 of the male (female) users. Also, based on the age of the user, time sale information of products that the user of that age group is likely to purchase is transmitted to the terminal 20 of the user of that age group. Also, based on the user's preference, time sale information of products that the user with that preference is likely to purchase is transmitted to the terminal 20 of the user with that preference.
The time sale information to be transmitted to the terminal 20 of the user may be determined based on a combination of two or more attribute information of the user.

Coupon information may also be transmitted to the terminal 20 based on the user's attribute information in the same way as the time sale information described above.

In addition, based on the user's purchase history, coupon information for products purchased less frequently (or purchased less frequently) by the user is transmitted to the terminal 20 of the user, based on the concept opposite to the time sale information described above. You may do so. This is intended to encourage the user to purchase a product with advantageous information so that the user can try a product that is rarely purchased.
As a non-limiting example, alcohol coupon information is transmitted to terminals 20 of users aged 20 or older (determined based on user attribute information (age or generation)) who do not often purchase alcohol. may

It should be noted that time sale information may also be sent to the terminal 20 of the user in the same way as the coupon information described above, as the time sale information of products that the user does not purchase often.

<Fourth embodiment>
The fourth embodiment is an embodiment for realizing collective addition of products to the shopping list described above.

The content described in the fourth embodiment can be applied to each of the other embodiments and each of the other modifications.
Moreover, the same code|symbol is attached|subjected about the component same as an already-appearing component, and description for the second time is abbreviate|omitted.

<Display screen>
FIG. 4-1 is a diagram showing an example of a shopping assistance application screen displayed on the display unit 24 of the terminal 20A in this embodiment.
The left side of FIG. 4-1 shows an example of a shopping list screen, and this example illustrates a method of collectively adding products to the shopping list based on a recipe that is referred to when cooking.

In this screen, a recipe input area RI41 for inputting information about a recipe to be searched and a search button BT41 for executing a search based on the input information are displayed below the in-app location display area. there is

In this example, the characters "curry" are input in the recipe input area RI41, the search button BT41 is tapped, and the search results are displayed. Specifically, in this example, search results for multiple recipes related to "curry", including "pork curry" and "butter chicken curry", are displayed under the mark containing the words "search by recipe". there is

By way of example and not limitation, when the display area for "Butter Chicken Curry" is tapped, the screen in the center of FIG. 4-1 is displayed. This screen is a recipe detail screen that displays detailed information about the recipe for "butter chicken curry." 2 cans, 1 can of tomato, 100 g of yogurt, etc.) are displayed, and how to make them is displayed below.

Also, in this example, the aforementioned shopping list addition icon IC31 is displayed in the vicinity of the area where the ingredients are displayed. When this shopping list addition icon IC31 is tapped, the screen on the right side of FIG. 4-1 is displayed as an example and not limitation.

This screen is a shopping list screen, and the ingredients of "butter chicken curry" displayed on the left side of Fig. 4-1 and the screen in the center of Fig. 4-1 are automatically added to the shopping list and displayed. . Specifically, in this example, "domestic chicken thigh (100 g)" is added to the list as an example of the chicken thigh that can be purchased at the store, and "4" is automatically entered as the quantity. Similarly, "onion" is added to the list, and "2" is automatically entered as its quantity, "canned tomato" is added to the list, and "1" is automatically entered as its quantity, and the store "○ × yogurt" is automatically entered as an example of a product that can be purchased at.
Note that in this example, user A. Since user A has purchased "XX yogurt" in the past, user A. Based on A's purchase history, "○ × Yogurt" of "Yogurt" is selected and automatically entered.

The shopping list on this shopping list screen is a building-in-progress (provisional) shopping list that is not associated with a store to purchase from.
This shopping list is conveniently referred to as a "shopping list under construction".

Also, by tapping the increase/decrease button associated with each product, it is possible to change the quantity to be purchased. , tapping the increase/decrease button to change the number of planned purchases, the amount can be adjusted.

When the "Show Map" button BT23 is tapped on the screen on the right side of FIG. 4-1, the screen on the left side of FIG. 4-2 is displayed as an example and not by way of limitation. In this example, a map image is displayed in the same manner as the left side of FIG. 3-6, and the total price for purchasing the products included in the shopping list is displayed in association with each store. Also, in this example, a "buy at this store" button is provided in the balloon from the icon image of each store for selecting when purchasing the products included in the shopping list at that store.

The screen on the left side of Figure 4-2 shows the state in which the "buy at this store" button in the balloon of "YY Super JJ Store" has been tapped. 2 The center screen is displayed.

This screen is a shopping list screen, and the items included in the shopping list on the screen on the right side of Figure 4-1, such as "domestic chicken thigh (100g)", "onion", "canned tomato", "○ × yogurt", etc. The products are displayed in association with the selected "YY Supermarket JJ Store". In other words, when the screen on the right side of Figure 4-1 was displayed, no store was associated with the shopping list, but based on the selection of the store (YY supermarket JJ store) on the screen on the left side of Figure 4-2 4-2, the selected "YY Supermarket JJ Store" is associated and displayed as a list of "YY Supermarket JJ Store".

Also, based on the product price of "YY Super JJ Store", the price per "domestic chicken thigh (100g)" is "98 yen", the price per "onion" is "77 yen", " "198 yen" is displayed as the price for one canned tomato, and "218 yen" is displayed as the price for one "○ x yogurt". Among these items, "domestic chicken thigh (100 g)" is a bargain item at "YY Supermarket JJ Store", so a "bargain" mark is displayed in association with it. In addition, the number of planned purchases displayed on the screen on the right side of FIG. 4-1 is also displayed on this screen.

This example shows a state in which the display area of "○ x Yogurt" is tapped and selected, and in this case, the screen on the right side of FIG. 4-2 is displayed as an example, not as a limitation.
This screen is a price comparison screen that displays information about the selected "○ × Yogurt". An enlarged image of "○ x Yogurt", the product name, and the price at this store ("218 yen" in this example) are displayed.

In addition, in the area where the price list at the bottom is displayed, information including the price of "○ × Yogurt" at each of the other multiple stores is displayed. The product price of "○ × Yogurt" is displayed as the lowest price ("198 yen" in this example).

Here, user A. It is possible that A wants to purchase "XX yogurt" at the lowest price. In this case, the add shopping list icon IC31 displayed in association with the image of "XX Yogurt" in the frame displaying the information of "XX Yogurt" displayed in association with "XX Mart JJ Store" is tapped. is selected, the selected "XX Yogurt" is added to the list of "XX Mart JJ Store" in the shopping list.

In this case, as a non-limiting example, display the list of "XX Mart JJ Store" including "XX Yogurt" under the list of "YY Super JJ Store" on the shopping list screen in the center of Fig. 4-2. can be Then, it is possible to delete "○×Yogurt" from the list of "YY supermarket JJ store" on the shopping list screen in the center of FIG. 4-2.
In addition, unlike this, it is also possible not to delete "XX Yogurt" from the list of "YY Supermarket JJ Store".

Also, unlike the above example, for stores other than "YY Super JJ Store" displayed on the map image on the left screen of Figure 4-2, "YY Super JJ Store" on the screen in the center of Figure 4-2 A similar list may be displayed below the list of "YY Supermarket JJ". In this case, as an example and not a limitation, the list may or may not be displayed in order of distance from the designated position (shortest walking time).

<Processing>
FIG. 4-3 is a flowchart showing an example of the flow of processing executed by each device in this embodiment, and is an example of processing when the processing of FIGS. 1-13 is applied.
Since the same applies to the case where the processing of FIG. 1-11 is applied, illustration and description are omitted here.
Also, it is not essential for the user of the terminal 20A to participate in counting the receipt information. Therefore, the steps A110 to A140 in the terminal 20A and the steps S110 to S130 in the server 10 may be omitted, and the steps after A210 may be executed.

After A220, the control unit 21 of the terminal 20A collectively adds shopping list information for adding the products to the shopping list (in this example, the "shopping list under construction" with no associated store to purchase). , to the server 10 via the communication I/F 22 (A410).

Specifically, by way of example and not by way of limitation,
(b1) Products selected by the user without specifying the store (b2) Recipe ingredients selected by the user It can be sent to the server 10 .

In (b1), as an example and not as a limitation, one or more products are selected from among the products that are displayed as "frequently bought products" on the price comparison screen on the left side of Fig. 3-4 and that are not associated with a store. In this case, the shopping list batch addition information can be transmitted to the server 10 .

As a non-limiting example, the shopping list addition icon IC31 corresponding to the product displayed in association with the store on the price comparison screens shown in the center of FIG. 3-4 and the right side of FIG. 3-4. is tapped, display information asking the user whether or not to include the product in the store list. Then, if inclusion in the store list is not selected, shopping list batch addition information may be transmitted to the server 10 so that the product is included in the shopping list under construction.

When transmitting the shopping list batch addition information based on the recipe, the control unit 21 of the terminal 20A receives and displays the recipe information from the server 10 based on the user input before performing the processing of A410. can be made

After S220, the control unit 11 of the server 10 performs a shopping list batch addition process (S410). Specifically, based on the product ID and the planned number of purchases included in the received shopping list batch addition information, user A.A. Update the shopping list data included in the account management data for the application ID of A. The received product ID can be stored as the product ID to be purchased. As the planned purchase product name, the product name specified from the product price management data corresponding to this planned purchase product ID can be stored. The planned purchase quantity can store the received planned purchase quantity.

In addition, since this is a shopping list under construction and no store is associated with it, the planned purchase store ID can be "NULL". In addition, since the store is not associated and the product price cannot be uniquely specified, the planned purchase price can also be set to "NULL".

Next, the control unit 11 of the server 10 sets the shopping list obtained as the processing result of S410 to the shopping list under construction, and transmits shopping list information under construction, which is the information thereof, to the terminal 20A through the communication I/F 14 (S420 ).

Although the planned purchase price cannot be uniquely specified, as shown in the column of "○ × Yogurt" in the display screen on the right side of FIG. Information such as the past purchase price of the product by A (as an example, but not as a limitation, the previous purchase price) and the average price of the product price stored in the product price data by store for the product, etc. It may be included in the list information and transmitted to the terminal 20A.

When the shopping list information under construction is received from the server 10 through the communication I/F 22, the control unit 21 of the terminal 20A displays the received shopping list information under construction on the display unit 24 (A420). An example of this may be the information displayed on the screen on the right side of FIG. 4-1.

After S420, the control unit 11 of the server 10 sets the information obtained by calculating the total amount for each store when purchasing all the products included in the shopping list information under construction as price information for each store in the shopping list, as an example and not as a limitation. , is transmitted to the terminal 20A through the communication I/F 14 (S430).

When the price information for each shopping list store is received from the server 10 through the communication I/F 22, the control unit 21 of the terminal 20A displays the received price information for each shopping list store on the display unit 24 (A430). An example of this may be the information displayed on the screen on the left side of FIG. 4-2.

After that, the control unit 21 of the terminal 20A transmits purchase store information including the store ID corresponding to the selected store to the server via the communication I/F 22 based on the user's input for selecting the store via the input/output unit 23. 10 (A440).

After S430, when the purchase store information is received from the terminal 20A through the communication I/F 14, the control unit 11 of the server 10 performs shopping list update processing (S440). Specifically, the shop ID included in the received purchase shop information is stored and updated as the planned purchase shop ID of the shopping list data. In addition, the product price of the planned purchase product at the store is stored and updated as the planned purchase price of the shopping list data.

Next, the control unit 11 of the server 10 transmits the shopping list information obtained in S440 to the terminal 20A through the communication I/F 14 (S450). Then, the control unit 11 of the server 10 terminates the process.

When the shopping list information is received from the server 10 through the communication I/F 22, the control unit 21 of the terminal 20A displays the received shopping list information on the display unit 24 (A450). An example of this can be the information displayed on the screen in the middle of FIG. 4-2. Then, the control unit 21 of the terminal 20A terminates the process.

<Effects of the fourth embodiment>
In this embodiment, when a recipe (not limited, but an example of a first recipe) is selected by the user of its own terminal 20, the target terminal 20 adds the ingredients to a shopping list (not limited, but an example of a list). Control for inclusion is performed by the control unit 21 . The target terminal 20 is configured to display the total price information of the materials included in the shopping list on the display unit 24 for each store.
As an example of the effect of the embodiment obtained by such a configuration, the ingredients of the first recipe are included in the list based on the selection of the first recipe by the user of the terminal, and then the ingredients included in the list are added to the list. The total amount information can be displayed for each store and notified to the user.

In addition, in the present embodiment, when a recipe (not limited, but an example of a first recipe) is selected by the user of the terminal 20 itself, the target terminal 20 adds the ingredients to a shopping list (not limited, but an example of a list). ) is performed by the control unit 21 . Then, the target terminal 20 displays on the display unit 24 information for selecting or sorting the stores from which the ingredients included in the shopping list are purchased (not limiting, but an example of information on the stores from which the ingredients included in the list are purchased). The configuration to be displayed is shown.
As an example of the effect of the embodiment obtained by such a configuration, the ingredients of the first recipe are included in the list based on the selection of the first recipe by the user of the terminal, and then the ingredients included in the list are added to the list. The user can be informed of or made to use information about the store where the product is purchased.

<Fourth Modification (1)>
In the above embodiment, the user may be provided with information about shopping for items included in the shopping list under construction.

FIG. 4-4 is a diagram showing an example of a shopping assistance application screen displayed on the display unit 24 of the terminal 20A in this modification. Here, an example of a shopping display screen when products corresponding to the ingredients of the recipe shown on the right side of FIG. 4-1 are collectively added to the shopping list under construction is shown.

The left side of FIG. 4-4 is a screen corresponding to the left side of FIG. 4-2, but the display is partially different.
Specifically, in the upper part of the display area of the map image, a "calculate shopping" button BT43 for performing calculations regarding shopping is displayed. When this "calculate shopping" button BT43 is tapped, a display such as that shown on the right side of FIG. 4-4 is provided as an example and not as a limitation.

Specifically, route setting information RS41 for setting a shopping route is displayed in the center of the display area of the map image. This route setting information RS41 contains, as a non-limiting example, price-prioritized route information, efficiency-prioritized route information, and balance-prioritized route information. information.

The price-prioritized route is, as an example, not a limitation, a route in which the price of the product is prioritized. can be root.

Efficiency-prioritized route is not a limitation, but a route that prioritizes efficiency such as time and distance, and is not a limitation, but an example of the time required to purchase items included in the shopping list under construction. It can be a route that minimizes the distance traveled.

A balance priority route may be, by way of example and not limitation, a compromise route between a price priority route and an efficiency priority route.

On the right side of FIG. 4-4, the “balance priority route” of these routes is shown tapped and selected. In this case, by way of example and not limitation, the screen on the left side of FIGS. 4-5 is displayed.

In the screen on the left side of FIG. 4-5, the balance-priority route is displayed on the map image based on the calculation result of the balance-priority route. Specifically, as a non-limiting example, move to "XX Mart JJ store" in 3 minutes on foot from the designated position indicated by mark MK21 along with the characters "balance priority" so as to be superimposed on the map image, and then , and information about the route from "XX Mart JJ Store" to "YY Supermarket JJ Store" in 10 minutes on foot. Also, this route is displayed in color on the map image.

In addition, the subtotal amount of "618 yen" for products purchased at "XX Mart JJ store" is displayed in the balloon of "XX Mart JJ store", and the subtotal amount for products purchased at "YY Super JJ store" is "714 yen". is displayed in the balloon of "YY supermarket JJ store". When these amounts are totaled, it becomes "1,332 yen", which corresponds to the amount of "1,332 yen" for the balance priority route shown in the screen on the right side of FIG. 4-4.

As a non-limiting example, when the balloon of "XX Mart JJ store" is tapped, the screen shown in the center of FIG. 4-5 is displayed as a non-limiting example. In this example, information about products to be purchased at "XX Mart JJ store" when this route is adopted is displayed in a balloon separate from the icon image of "XX Mart JJ store".
Although illustration is omitted, when the balloon of "YY Super JJ Store" is tapped, information on products to be purchased at "YY Super JJ Store" is similarly displayed when this route is adopted.

At the bottom of the map image, a "Take this route" button BT45 for adopting the proposed route is displayed, and when tapped, the screen on the right side of Fig. 4-5 is displayed as an example and not as a limitation. be done.
This screen displays a shopping list in which the products included in the shopping list under construction are sorted by store based on the applied route. Since the order of shopping is "XX Mart JJ store" → "YY supermarket JJ store", the list of "XX Mart JJ store" is displayed above and "YY supermarket A list of "JJ stores" is displayed. By displaying the list in an order consistent with the route in this way, it is possible to realize a display that is easy for the user to understand.

Here, the calculation method will be described by taking the above balance priority route as an example.
By way of example and not limitation, the following information is input.
(I1) Shopping list information under construction (I2) Specified location information (I3) Each store location information

Based on the input information, as an example, but not as a limitation, a range within a set distance from a specified position (a range within a radius of 1 km as an example, not as a limitation), or within a set time on foot from a specified position A range (a range within a 10-minute walk as an example, not a limitation) is determined as a range in which the user can shop around (hereinafter referred to as a "purchasable range"). Then, the stores located within the determined shopping possible range are set as shopping candidate stores (hereinafter referred to as “shopping candidate stores”).

It should be noted that the user of the terminal 20 may be able to set the information for determining the possible shopping range (as an example, not as a limitation, such as the above set distance and set time). In other words, each user may be able to independently set the extent of the purchaseable range on his/her own terminal 20 .

After that, combinations of buying-around candidate stores are determined, and for each combination, the buying-around cost C is calculated based on the following two values as an example and not as a limitation.
(J1) Total purchase amount when purchasing the products included in the shopping list under construction at the lowest price of the shopping candidate stores included in the combination (J2) Starting from the specified position, shopping candidate stores included in the combination Time required to walk around

The required time of (J2) can be calculated as a minimum required time using a dynamic programming method (as an example, not a limitation, Dijkstra's method) or the like, as an example and not a limitation.

The shopping cost C is formulated as the following equation (1) as an example and not as a limitation.
Purchasing cost C = total purchase price + required time x time cost parameter (1)

A specific description will be given.
As a non-limiting example, it is assumed that three stores, "Store A", "Store B", and "Store C", are selected as candidate shopping stores. Also, in this example, it is assumed that "store B" and "store C" are located in the same direction when viewed from the specified position.

In this case, the combinations of these three stores are "Store A", "Store B", "Store C", "Store A & Store B", "Store B & Store C", "Store A & Store C", "Store A & Store B & Store C”. For these seven combinations, as an example and not as a limitation, assume that the total purchase price and required time are calculated as follows.
"Store A": total purchase amount "11,750 yen", required time "7 minutes"
"Store B": total purchase amount "12,210 yen", required time "6 minutes"
"Store C": total purchase amount "9,880 yen", required time "10 minutes"
"Store A & Store B": Total purchase amount "11,960 yen", required time "18 minutes"
"Store B & Store C": Total purchase amount "9,470 yen", required time "11 minutes"
"Store A & Store C": Total purchase amount "9,620 yen", required time "24 minutes"
"Store A & Store B & Store C": Total purchase price "9,390 yen", required time "35 minutes"

The time cost parameter is set, by way of example and not limitation, as "50" as a value that finds a consideration of 50 Yen per minute of duration. In this case, if the shopping cost C is calculated according to the formula (1), it is calculated as follows.
“Store A”: shopping cost C “12100”
“Store B”: shopping cost C “12510”
“Store C”: shopping cost C “10380”
“Store A & Store B”: Shopping cost C “12860”
“Store B & Store C”: Purchasing cost C “10020”
"Store A & Store C": Shopping cost C "10820"
“Store A & Store B & Store C”: Shopping cost C “11140”

From among the shopping costs C calculated for each combination of shopping candidate stores, the combination of shopping candidate stores with the minimum shopping cost C is obtained and output. In the above example, the combination of shopping candidate stores with the lowest shopping cost C is "store B & store C." As a result, the route of "store B & store C" is output as a calculation result of the balance priority route.

Although the required time is multiplied by the time cost parameter in equation (1), the same calculation may be performed by multiplying the total purchase price by the money cost parameter.
Alternatively, the total purchase amount and the required time may be multiplied by a cost parameter to make (J1) and (J2) dimensionless to calculate the shopping cost C. FIG.

Conceptually, in the above example, considering the efficiency (time efficiency, movement efficiency), the nearest store from the specified position among "store A", "store B", and "store C" is (J2). The required time is minimized ("6 minutes" for "store B" in the above example). However, when all the products included in the shopping list under construction are purchased at "store B", the total amount is not always the minimum. For this reason, as described above, the shopping cost C is calculated in consideration of the required time and the total purchase amount, and the combination of shopping candidate stores that minimizes this is determined.

Although the balance-prioritized route is exemplified here, in the price-prioritized route, it is only necessary to find a combination of buying-around candidate stores that minimizes the value of (J1). In other words, the total purchase amount is used as the shopping cost C to find a combination of shopping candidate stores.

In the efficiency-prioritized route, a combination of shopping candidate stores that minimize the value of (J2) may be found. In other words, a combination of shopping candidate stores may be obtained using the required time as the shopping cost C. FIG.

Although a specific example of the method of calculating the route has been shown so far, this is merely an example, and the method is not limited to the above method.

Moreover, the above contents may be similarly applied not only to shopping for products but also to shopping for services.
Also, the above contents may be similarly applied to the purchase of a combination of goods and services.

Also, although an example of calculating and proposing a route has been shown here, the present invention is not limited to this.
Instead of calculating and suggesting a route, or in addition to this, the control unit 11 of the server 10 may, based on the shopping list information under construction, determine, by way of example and not limitation, "I purchased product X at store A. , purchase product Y at store B, . . .

Also, at least one of the three types of routes, the price priority route, the efficiency priority route, and the balance priority route, may be displayed, and it is not essential to display all of them.

Further, instead of the above processing (calculation) being performed by the control unit 11 of the server 10, the information necessary for the processing may be obtained by the terminal 20 from the server 10 and then performed by the control unit 21 of the terminal 20. good.

In addition, the above processing (calculation) may be performed not only on the ingredients of the recipe described above, but also on the products arbitrarily selected by the user and added to the shopping list under construction.

FIG. 4-6 is a flow chart showing an example of the flow of processing executed by each device in this modified example.
After A220 in FIG. 4-3, the control unit 21 of the terminal 20A determines whether or not the user has input through the input/output unit 23 to add products without specifying a store (A405). . If it is determined that an input has been made to specify a store and add products (A405: NO), the control unit 21 of the terminal 20A moves the process to A310 in FIG. 3-8 as an example and not as a limitation.
On the other hand, if it is determined that an input has been made to add a product without designating a store (A405: YES), the control unit 21 of the terminal 20A advances the process to A410.

<Fifth embodiment>
The fifth embodiment is an embodiment relating to a product delivery service.

The content described in the fifth embodiment can be applied to each of the other embodiments and other modifications.
Moreover, the same code|symbol is attached|subjected about the component same as an already-appearing component, and description for the second time is abbreviate|omitted.

In this embodiment, a product delivery service is exemplified, and the provider of this delivery service is called a "delivery service provider". In this embodiment, in the form of so-called shopping proxy, the products purchased by the user from the store using the shopping assistance application are picked up from each store by a delivery person (person) of the delivery service and delivered to the user. Illustrate the case. A delivery person may, by way of example and not limitation, deliver the goods by automobile (including trucks, etc.).

It should be noted that the shopping assistance service provider may serve as a delivery service provider and deliver the products of the store purchased by the user of the terminal 20 .

<Display screen>
FIG. 5-1 is a diagram showing an example of a shopping assistance application screen displayed on the display unit 24 of the terminal 20A in this embodiment.
The left side of FIG. 5-1 shows an example of a shopping list screen displaying a map image. In this example, the information on the total price when purchasing the products included in the shopping list at the above-mentioned "XX Mart JJ store" and the information on the total price when purchasing at the above-mentioned "YY Supermarket JJ store" are included. , each displayed in a speech bubble.

In addition, on this screen, information is displayed above the display area of the map image to recommend the user to purchase the product using the delivery service. Specifically, along with the image of the truck and the words "recommended delivery service", the total amount for purchasing the items on the shopping list using the delivery service and the "service recommended" for using the delivery service. "Use" button BT51 is displayed.

In this example, the total amount for purchasing products at "XX Mart JJ Store" is "11,399 yen", and the total amount for purchasing items at "YY Supermarket JJ Store" is "10,531 yen". ” is indicated by the display.

In this embodiment, the delivery fee using the delivery service is based on the amount per store (as an example, not limitation, "200 yen" or "210 yen" when visiting one store) as an example, not a limitation. can be determined.

In this case, the server 10, as an example and not a limitation, for each product included in the shopping list, based on the product price of each store within a range of 1 km radius from the designated position indicated by the mark MK21, Determine the store with the lowest price for the product. Based on the determination result, the server 10 calculates, for each store, the products purchased at the store and the subtotal amount (total amount) of the products purchased at the store. Then, the server 10 transmits the calculation result and the information about the delivery status of the product to the terminal 20 and causes the display unit 24 of the terminal 20 to display them.
Note that in this example, the server 10 performs the calculation without considering the delivery charge.

In this example, by the above calculation by the server 10, "XX Mart JJ Store" and "YY Supermarket JJ Store" as well as "ZZ Mart KK Store" and "YY Supermarket KK Store" are determined as an example and not as a limitation. It is assumed that it is selected by the server 10 .

When the "use service" button BT51 is tapped and the necessary information is entered, a delivery service screen regarding the delivery service for the products included in the shopping list is displayed, as shown on the right side of FIG. 5-1.
In this delivery service screen, the delivery charge (in this example, "840 yen" for 4 stores) is displayed below the display area of the map image. Further, for each of the four stores selected by the server 10, the subtotal amount (total amount) of the products purchased at the store is displayed in association with the store.

In this example, the sum of the subtotal amounts of the above four stores is "9,167 yen", which is the total amount when purchasing products at "XX Mart JJ store" shown in the screen on the left side of Figure 5-1. The amount is lower than both "11,399 yen" and the total amount of "10,531 yen" when purchasing products at "YY Super JJ Store".
Adding the delivery charge of "840 yen" results in "10,007 yen". there is

In the screen on the right side of Fig. 5-1, information including the words "product picking in progress" is displayed above the display area of the map image, and the user is notified that the product is currently being picked by the delivery person. . In addition, a check mark is displayed in association with a store where product picking has been completed, and the user is notified of the store where product picking has been completed. In addition, the current location information of the delivery person (delivery person's terminal) is displayed by an image of a truck in this example.

It should be noted that the server 10, based on the location information of the delivery person (delivery person's terminal), the store location information, the information of the delivery route, and the like, the time from the current location of the delivery person to the specified position indicated by the mark MK21. may be calculated and information about the calculated required time may be transmitted to the terminal 20 . Then, the terminal 20 may display the received information about the required time on the display unit 24 . As an example and not as a limitation, information such as "How many minutes will it take?" and "What time and what minutes will it arrive?"

Note that the server 10 may randomly determine the order in which the delivery staff picks up the products and inform the delivery staff.

In addition, the server 10 determines which route the delivery person takes based on a dynamic programming method (as an example, not a limitation, Dijkstra's method) or the like, with the departure point of the delivery person as the starting point and the specified position indicated by the mark MK21 as the end point. It is also possible to calculate whether the shortest route will be taken if the delivery person stops at the store, and to inform the delivery staff of the order of picking the products based on the calculation result.

In these cases, the server 10 may transmit information regarding the delivery of the goods, including the order in which the goods are picked, to a terminal carried by the delivery person, by way of example and not limitation. Then, the delivery staff can pick the products based on the information displayed on the display section of the terminal they own.

It should be noted that the delivery service provider may use a robot to deliver the product instead of using a delivery person (human) to deliver the product.
By way of example and not limitation, a delivery service provider may deliver goods using remotely operated (or autopiloted) autonomous drones.

In this case, as one method, the operator remotely controls the drone based on the route information transmitted from the server 10 to the terminal of the operator of the drone and directs the drone to each store. Specifically, by way of example and not limitation, a drone takes off from the origin and lands at the first store. The drone is then loaded with the first store's merchandise, either by that store's employees, or by a pre-deployed delivery service employee. After that, the drone takes off and heads to the next store. By repeating this process, the products of all the stores are finally delivered to the user.

It should be noted that even if the communication device provided in the drone receives the route information transmitted from the server 10, the control unit provided in the drone performs autopilot control, and the product is delivered in the same procedure as above. good.

In addition, it is possible to transition from the shopping assistance application to the net supermarket provided by the operator of each store. Then, when the user purchases the product at the transition destination net supermarket, the product may be delivered to the user.

As described above, the server 10 selects the store with the lowest product price for each product included in the shopping list based on the product price information of each store included in the predetermined range from the specified position. Optionally, the total amount can be presented to the user of terminal 20 .
However, when setting the shipping fee based on the amount per store as above, if the calculation is performed without considering the shipping fee, the number of stores where the product is purchased will increase, resulting in the shipping fee There is a possibility that the total amount including

Therefore, as an example and not as a limitation, the server 10 may consider the delivery charge and determine the store where the product is purchased so that the total amount including the delivery charge is minimized.

It should be noted that the server 10 may perform similar calculations for a combination of shops whose total amount including the delivery charge is not the smallest, and transmit the calculation result to the terminal 20 as a delivery service recommendation for display. . This is because some users may use the delivery service with the idea that they do not have to go shopping by themselves even if the price is not the lowest.

Also, unlike the above embodiment, the delivery charge may be set as a uniform amount regardless of the number of stores.
Further, in the case of immediate delivery or same-day delivery, the delivery fee may be increased.

<Others>
(1) Electronic Receipt As described above, instead of a paper receipt, the server 10 may analyze and total receipt information specified by an electronic receipt.
In this case, the terminal 20 that has acquired the electronic receipt may transmit the electronic receipt to the server 10, or a device such as a server of the store that issued the electronic receipt may transmit the electronic receipt to the server 10. You may do so.

(2) Categories As described in the fourth modification, categories may be provided for products and services, and price information and the like of the corresponding products and services may be displayed for each product category or service category. In this case, as described above, the store category is stored in the store registration data 154, and the product price management database 155C shown in FIG. 4-7, the account management database 159B shown in FIG. 4-8, etc. are applied. , based on these data, the same processing as the processing described in the above embodiment can be performed.

(3) Lowest Price Suggestion By way of example and not limitation, a shopping assistance service provider may become a retailer and sell items selected by the user within the shopping assistance application.

The shopping assistance service provider can acquire product price information of each store based on the receipt information collected by the server 10 from the terminal 20 (its user), as described in the above embodiment. . Therefore, as a non-limiting example, the server 10, as shown in the screen on the left side of FIG. Information on the total amount of the items is transmitted to the terminal 20 in association with each store and displayed, and the total amount that the shopping assistance service provider can provide at a lower price than the total amount for purchase at each store is calculated. In other words, the product price data collected from each store is used as big data to calculate the amount that the shopping assistance service provider can profitably sell. Then, by transmitting information on the calculated amount to the terminal 20 and displaying it on the display unit 24 of the terminal 20, it is proposed to the user of the terminal 20 that the product can be purchased from the shopping assistance service provider at a lower amount. do.
It should be noted that the proposal may be made for each product instead of for each shopping list.
