Therefore, when the customer inputs the customer ID and displays it in the customer ID display area 74 and presses the approval button 75, the controller executes the cart lending registration process.
By this cart lending registration process, the cart 22 is associated with the customer corresponding to the customer ID.
Subsequently, the customer performs a process of registering a product to be purchased or a product wondering whether or not to purchase in the shopping assist terminal device 23 placed on the cart 22 (step S12). The registration process for the product to be purchased will be described in detail later.

FIG. 12 is an explanatory diagram of a display example of a display immediately after registration of a product to be purchased or the like.
As shown in FIG. 12, the display screen 42 </ b> A of the display 42 displays a product list display operation area 83 and a map display area 90 for displaying an in-store map for displaying a guide route. ing.

  The product list display operation area 83 includes a product list display area 83A having a plurality of product name display fields CL in which the product name or category name of the product selected in the product selection operation area 82 is displayed as a product list to be purchased. A scroll operation unit 83B for scrolling the product name displayed in the display area 83A up and down, and a purchase planned product total price display for displaying the price of the purchase planned product registered to be displayed in the product list display area 83A Of the products to be purchased that are registered to be displayed in the column 83C and the product list display area 83A, the total amount of products that the customer has instructed to put in the shopping basket 31 placed on the cart 22 is displayed. A purchased product total amount display field 83D.

  In addition, the product list display operation area 83 displays, as a purchase planned product list, data of a purchase planned product group registered in advance in the route navigation system 25 from the personal computer at the customer's home via the communication network 12 by the customer. A shopping list reading button 83E for reading in, a shopping list saving button 83F for saving in the route navigation system 25 all of the purchase planned product lists to be displayed in the product list display area 83A, and a store A. A map confirmation button 83G for making it possible to confirm on the map the current position of the cart 22, the guidance route, and the display position of the product to be purchased registered to be displayed in the product list display area 83A; Car for purchasing a product scheduled for purchase registered to be displayed in the display area 83A It comprises a route search button 83H, a performing instruction to search for 22 guidance route to the route navigation system 25.

In the map display area 90, the product list display area 83A is displayed on the in-store map 91 on which the layout of the entrances and exits, the layout of each sales floor, the layout of the POS terminals constituting the POS system, and the layout of the cart rental location are displayed. The balloon icons BI1 to BI6 indicating the display locations of the products to be purchased in the store A and the cart current position mark 22N as the current position of the cart 22 are displayed.
In this case, the cart current position mark 22N indicating the current position of the cart 22 is based on the radio wave intensity at the wireless access point 26 that can communicate with the shopping assist terminal device 23 mounted on the cart 22, a communication error rate, or the like. It is displayed at a position corresponding to the calculated position of the cart 22.

  On the other hand, in each product name display column CL of the product list display area 83A, a balloon icon index PID indicating a correspondence relationship with the balloon icons BI1 to BI6, and a customer has picked up a product to be purchased (a shopping basket to purchase a product) If the product has already been acquired), a check mark box CHK that displays a check mark by tapping the area, a product name display column NAM of a product to be purchased, and a product displayed in the product name display column NAM Product purchase number display field NUM for displaying the number of purchases, a count button CNT for changing the number of purchases displayed in the product purchase number display field NUM, a price display field PR for displaying the price of the product to be purchased, and the customer Has a hold button KP for setting that the purchase of the product to be purchased is put on hold. In FIG. 12, the hold button KP is indicated by a broken line because it is in an unset state.

  As described above, since the hold button KP is not set in FIG. 12, the products registered in the shopping list are “carrot”, “plastic bottle tea”, “british fillet”, and “bread”. Assuming that there are only six types of “washing bath detergent ●●” and “handkerchief”, the planned purchase price will be the same as the purchase price display column NUM for each planned purchase product. It is 864 yen which is the sum total of the sum of the number of purchases displayed in.

FIG. 13 is an explanatory diagram of a display example of the display when one of the hold buttons KP is set immediately after registration of a product to be purchased or the like.
In FIG. 13, the hold button KP corresponding to the product name display column CL of the fifth product to be purchased from the top “detergent for bath ●●” is set.
As a result, the purchase product “Bath Kettle Detergent ●●” has been put on hold, so the products on the shopping list are “carrot”, “plastic bottle tea”, “british fillet”, Of the 6 types of “bread”, “bathroom detergent ●●” and “handkerchief”, only 5 types of “carrot”, “plastic bottle tea”, “british fillet”, “bread bread” and “handkerchief” It is treated as an actual purchase planned product, and the planned purchase price is the sum of the number of purchases displayed in the product purchase number display column NUM to the amount displayed in the price display column PR for the five types of purchase planned products The total of 666 yen is to be displayed.

When the route search button 83H is tapped in the state shown in FIG. 13, the route navigation system 25 performs the guidance route setting processing in the store A assuming that the registration processing of the product to be purchased is completed (step S13). ).
In this case, for setting the guidance route, for example, a technique for searching for a circular route using a genetic algorithm (see, for example, Japanese Patent Laid-Open No. 2007-177484) is used.

Here, the reason why the circular route search using the genetic algorithm is performed is as follows.
In general, in the case of a roundabout route search, when the roundabout calculation is performed with the current general arithmetic processing device when the number of the rounding points increases, a large amount of calculation (amount and time) is required and practically difficult. This is because, when a more suitable approximate solution is obtained, the amount of calculation is reduced and the calculation is performed in a short time.
When the guide route setting process is completed, the route navigation system 25 notifies the guide route data to the shopping assist terminal device 23, and the shopping assist terminal device 23 displays the set guide route in the map display area 90. Display superimposed on the map.

FIG. 14 is an explanatory diagram illustrating an example of a display screen when the guidance route is displayed in the map display area.
As shown in FIG. 14, because the purchase planned product “detergent for bath ●●” is put on hold, the planned purchase products “carrot”, “plastic bottle tea”, “british fillet”, “bread bread” ”,“ Handkerchief ”, and the guidance route NR to the checkout location where the POS terminals constituting the POS system 21 are arranged is displayed.

FIG. 15 is an explanatory diagram of another example of the display screen when the guidance route is displayed in the map display area.
That is, when the route search button 83H is tapped in the state shown in FIG. 12, or in the state shown in FIG. 14, the hold button KP corresponding to the planned purchase product “bath kettle detergent ●●” is tapped to hold. When the state is canceled, the guide route is set or the guide route is reset (step S13). As shown in FIG. 15, “carrot”, “plastic bottle tea”, “british fillet”, “bread” ”,“ Bath Detergent ●● ”, and“ Handkerchief ”, the guidance route NR1 to the checkout location where the POS terminal constituting the POS system 21 is arranged is displayed. .

As described above, because the purchase planned product can be included in the shopping list as a hold state, while registering as if it was a handwritten shopping list, You will be able to purchase products easily.
Then, the controller 41 of the shopping assist terminal device 23 performs route guidance processing for guiding the purchase planned product included in the purchase planned product list to the display place in the store A (step S14). This route guidance process will be described in detail later.

Thereafter, the controller 41 of the shopping assist terminal device 23 monitors the operation of the operation unit 43 by the customer, and determines whether or not a route change is necessary due to a predetermined operation (step S15). Here, as a predetermined operation that requires a route change, an operation of adding, changing, or deleting a product to be purchased can be considered.
If it is determined in step S15 that a route change is required due to a predetermined operation (step S15; Yes), the route navigation system 25 is notified via the wireless access point 26, and the store is again stored. A guide route setting process in A is performed to notify a new guide route, and a route guide process according to the new guide route is performed (step S13).

If it is determined in step S15 that a predetermined operation has not been performed and no route change is required (step S15; No), the controller 41 of the shopping assist terminal device 23 completes the acquisition (pickup) of the purchase target product. It is determined whether or not it is in the state (step S16).
If it is determined in step S16 that acquisition of all purchase target products has not yet been completed (step S16; No), the process proceeds to step S14 again to continue route guidance.
On the other hand, if it is determined in step S16 that all the purchase target products have been acquired (step S16; Yes), the POS terminals constituting the POS system 21 are arranged as part of the route guidance process. Guidance processing to the checkout office is performed (step S17).

Then, a settlement process is performed on the purchased product by cash or credit payment by the customer (step S18), and the cart 22 is returned to the predetermined return position to perform the cart return process, and the correspondence between the cart 22 and the customer. Processing for canceling the relationship is performed (step S19).
Here, the route navigation system 25 updates the purchase history data 65 </ b> C and the previous purchase data 65 </ b> D in the customer master DB 65 at the stage where the payment process is performed.

Next, the registration process for the products to be purchased will be described in detail.
FIG. 16 is an explanatory diagram of a product registration screen in the shopping assist terminal device immediately after the cart rental registration process.
The product registration screen 81 is displayed on the display screen 42 </ b> A of the display 42 of the shopping assist terminal device 23.

  The product registration screen 81 can be broadly divided into a product selection operation area 82 for selecting a product to be purchased (a product to be included in the shopping list), a product list to be purchased (a shopping list), and the product list display operation area 83 described above. It is equipped with.

  The product selection operation area 82 includes a tab selection area 82A for selecting, using a tab, a selection method of a category, a product name, or a leaflet to which the product belongs, and a plurality of selection item display fields SL. And a selection item display area 82B for displaying a selection item (category name or product name) corresponding to the selection method selected in the tab selection area 82A, and the display contents of the selection item display area 82B in the vertical direction. A scroll operation unit 82C for scrolling.

In FIG. 16, the tab selection area 82A is provided with a category selection tab 84, a product name selection tab 85, and a leaflet selection tab 86, and the category selection tab 84 is selected (indicated by a bold line in FIG. 16). .)
Here, the category classification will be described.
In the present embodiment, the product category means a category to which a plurality of products belong.

  FIG. 17 is an explanatory diagram of the category structure. FIG. 17 shows a case where the category structure has a five-level tree structure of the first category CT1 to the fifth category CT5. Depending on the product category, it is not always necessary to adopt a five-layer structure, and a two-layer or more four-layer hierarchy or a six-layer or more layer structure may be used.

  Of the first category CT1 to the fifth category CT5, the lowest category, the fifth category CT5, actually stores only the product code for specifying the product, and the product for displaying the actual product name. Although the structure which refers to master DB61 is taken, in FIG. 17, the brand name is also described together for easy understanding. Of the categories belonging to the first category CT1, the product name data may be stored together with the product code in the lowest category. Specifically, when the third category CT3 is the lowest category, product name data and product codes may be stored in the third category CT3.

In the present embodiment, as specific examples of the first category data corresponding to the first category (top category) CT1, “food”, “fashion”, “drink / sake”,..., “Purchase history”, “Last purchase”, “By purpose”, etc.
As specific examples of the second category data corresponding to the second category (upper category) CT2, when the first category data = “by purpose”, “cooking”, “design change”, “daily carpenter”, “ "General cleaning", "Gardening" and the like.

Furthermore, as a specific example of the third category data corresponding to the third category (intermediate category) CT3, when the second category data = “main cleaning”, “around the kitchen”, “window / sash / screen door”,. “Lighting fixtures”, “around the bathroom” and the like.
Furthermore, as specific examples of the fourth category data corresponding to the fourth category (lower category) CT4, when the third category data = “around the bathroom”, “detergent for bathtub”, “detergent for tile”, “bath cleaner” And the like.

  Further, as the fifth category corresponding to the fifth category (lowest category) CT5, a product code such as a JAN code corresponding to the product is stored. For example, in the case of the example in FIG. 17, when the product is “△ ▽ Bath Detergent”, the product code is “49DDDDDEEEEEF” (D, E, and F each use a predetermined number for each product).

FIG. 18 is a detailed process flowchart of the shopping list registration process of the embodiment.
The controller 41 of the shopping assist terminal device 23 selects any one of the category selection tab 84, the product name selection tab 85, and the leaflet selection tab 86 in the tab selection area 82A of the product selection operation area 82 on the display screen 42A of the display 42. It is determined whether the selected tab has been selected (step S31).

  If the category selection tab 84 is selected in step S31 (step S31; category), the controller 41 reads the category master DB 62 when the category structure as shown in FIG. In step S32), as shown in FIG. 16, category names belonging to the first category are displayed as selectable categories in the selection item display area 82B (step S33). Specifically, in the example of FIG. 1, categories (selectable from “food”, “fashion”, “drink / sake”,..., “Purchase history”, “previous purchase”, “by purpose”, etc.) The first category CT1) is displayed as a category list.

Subsequently, the controller 41 determines whether or not a category selection operation has been performed in which the customer selects any category (first category) via the operation unit 43 (step S34).
If it is determined in step S34 that the customer has not yet selected any category (first category CT1) and the selection operation has not been performed (step S34; No), the controller 41 enters a standby state.

  In the determination in step S34, when the customer performs a selection operation for selecting any category (first category CT1) (step S34; Yes), the selection operation performs an operation for registering the category in the shopping list or It is determined which operation is an operation for instructing display of a category (or product) immediately below the category (step S35). Here, examples of the operation for registering the category in the shopping list include a long press operation in which the selection item display field SL displaying the category to be registered is pressed for a predetermined time or longer. An operation for instructing display of a category (or product) immediately below the category includes an operation of tapping the selection item display field SL displaying the category to be registered.

  If it is determined in step S35 that an operation for registering the category in the shopping list is performed, it is determined whether or not the category (first category CT1) is a category that can be registered in the shopping list (step S36). Here, the category whose category can be registered in the shopping list is a category in which all the products belonging to the category are displayed in a collective position in the store A, and the customer is guided to the corresponding display position. For example, the customer can easily find a product belonging to the category.

If it is determined in step S36 that the category (first category CT1) is a category that can be registered in the shopping list (step S36; Yes), the controller 41 adds the selected category name to the shopping list. It is displayed (step S37).
Subsequently, the controller 41 determines whether or not a predetermined registration end operation has been performed (step S38).
If it is determined in step S38 that a predetermined registration end operation has been performed, the process ends.
If the predetermined registration end operation is not performed in the determination in step S38 (step S38; No), the controller 41 proceeds to step S31 again, and performs the same process.

  On the other hand, if it is determined in step S36 that the category (first category CT1) is not a category that can be registered in the shopping list (step S36; No), the category immediately below the selected category (second category CT2). Is the lowest category including the product code (step S39).

  If it is determined in step S39 that the category immediately below the selected category (second category CT2) is the lowest category including the product code (step S39; Yes), the controller 41 searches the product master DB 61. (Step S40), the product names of the products belonging to the category (second category CT2) immediately below the selected category are displayed so as to be selectable (Step S41).

  On the other hand, if it is determined in step S39 that the category immediately below the selected category (second category CT2) is not the lowest category including the product code (step S39; No), the process proceeds to step S33 again. Then, the category name (or product name) belonging to the category (second category CT2) immediately below the selected category is displayed so as to be selectable (step S33).

FIG. 19 is an explanatory diagram of a display example of the second category.

FIG. 22 is an explanatory diagram of a display example of product names of products belonging to the fifth category.
In the determination of step S39, the fifth category CT5 is determined that the category immediately below the selected fourth category CT4 (fifth category CT5) is the lowest category including the product code (step S39; Yes). The controller 41 searches the product master DB 61 (step S40), and displays the product names of products belonging to the category (fifth category CT5) immediately below the selected category in a selectable manner (step S41).

Specifically, when the selection item display field SL (SLS) corresponding to “bathroom detergent” is selected as the fourth category CT4, as shown in FIG. “Bath kettle detergent ●●”, “Super OO bath kettle”,…, “Bath kettle ace”, “Bath kettle clean □□”, “Bath kettle detergent △ ▽ For one hole” The product name (fifth category CT5) is displayed.
In this state, when the customer performs a product selection operation for selecting any product name such as tapping any selection item display field SL (step S42), the controller 41 puts the selected product into the shopping list. Additional registration is performed (step S43), and the price is added to the planned purchase price and displayed on the display screen 42A of the display 42.

Subsequently, the controller 41 determines whether or not a predetermined registration end operation has been performed (step S38).
If it is determined in step S38 that a predetermined registration end operation has been performed (step S38; Yes), the process ends.
If the predetermined registration end operation is not performed in the determination in step S38 (step S38; No), the process proceeds to step S31 again, and the same process is performed thereafter.

Further, in the determination of step S31, when a tab is selected and the product name selection tab 85 is selected (step S31; product), the shopping assist terminal device 23 inputs the product name or a part of the product name as text. A product name input box (not shown) for prompting the customer to do so is displayed on the display screen.
When the customer inputs the product name or a part of the product name in the product name input box, the route navigation system 25 searches the product master DB (step S44), and the product input via the shopping assist terminal device 23. The product name of the product that matches the search condition having the name or part of the product name is displayed in the product selection area (step S45).

As a result, when the customer performs a product selection operation for selecting one of the products displayed in the product selection area (step S46), the selected product is displayed in the shopping list (step S47).
Subsequently, the controller 41 determines whether or not a predetermined registration end operation has been performed (step S38).
If it is determined in step S38 that a predetermined registration end operation has been performed (step S38; Yes), the process ends.

If the predetermined registration end operation is not performed in the determination in step S38 (step S38; No), the process proceeds to step S31 again, and the same process is performed thereafter.
In step S31, when the tab is selected and the leaflet selection tab 86 is selected (step S31; leaflet), the shopping assist terminal device 23 searches the leaflet master DB (step S48). The flyer image data corresponding to the electronic flyer that can be displayed is read out, and the electronic flyer is displayed on the display screen 42A of the display 42 of the shopping assist terminal device 23 (step S49).

As a result, when the customer performs an area selection operation for tapping any position on the display screen of the electronic leaflet (step S50), it is converted into coordinates on the electronic leaflet corresponding to the tap position, and the area coordinate data 63B is referred to. Then, the area corresponding to the tap position is identified, the commodity code is read from the commodity code data 63C corresponding to the identified area, the commodity master DB 61 is further searched, and the commodity name of the commodity corresponding to the commodity code is the shopping list. (Step S51).
Subsequently, the controller 41 determines whether or not a predetermined registration end operation has been performed (step S38).

If it is determined in step S38 that a predetermined registration end operation has been performed (step S38; Yes), the process ends.
If the predetermined registration end operation is not performed in the determination in step S38 (step S38; No), the process proceeds to step S31 again, and the same process is performed thereafter.

By the way, in the above description, it was not explained in detail about when to register a category in the shopping list, but the reason for adopting such a configuration is as follows.
Some customers sell what they want to buy in situations where they understand what they want to buy, but are not sure what they want to buy. If you are guided to the sales floor, you can actually see the product and choose from price, function, and usage.

For example, in the case of the example in FIG. 21, when the customer is going to purchase a bath detergent and does not know the specific detergent name, the product belonging to “bath cleaner” is displayed. It is enough to guide you to the place you are.
Therefore, in this embodiment, in such a case, the route setting is performed by registering the category of “detergent for bath tub” instead of the product so that route guidance can be performed.

Hereinafter, a case where route guidance is performed in a higher category that is not a product name will be described with a specific example.
As described above, when any category list is displayed and any item belonging to the category is selected, if the lower category exists, the lower level corresponding to the selected item is displayed. When a category list is displayed and one of the items belonging to the category is to be added to the shopping list, for example, one of the items belonging to the category is long pressed. Thereby, the item is added to the shopping list without shifting to the display of the lower category list.

Referring to FIG. 14 again, in the state of FIG. 14, since no check mark is displayed in the check mark box CHK for all the products, it is assumed that there are no products already acquired in the shopping basket. In the amount display column, 0 yen is displayed.
Along with this, the display position of the balloon icon BI5 represents a place where a large number of bath pot detergents that are products to be purchased are displayed.

FIG. 23 is a process flowchart of route guidance and settlement processing.
When the route search button 83H is tapped in the state where the screen of FIG. 13 is displayed, the controller 41 of the shopping assist terminal device 23 applies a route search program applying the above-described genetic algorithm so that the moving distance of the customer is further shortened. Accordingly, the route setting process is performed (step S61).

Here, FIG. 14 will be referred to again.
When the route setting process is completed, the controller 41 displays the in-store map 91 on which the guidance route NR is displayed on the display screen 42A of the display 42 as shown in FIG. 14 (step S62).
Subsequently, when the customer starts moving in the store A according to the guidance route NR while pushing the cart 22, the controller 41 performs processing when the cart 22 moves in the store (step S63), and current position detection processing of the cart 22 (step S63). Step S64) is performed in parallel.

Here, the processing at the time of moving in the store means that, for example, when a customer wants to purchase a product and puts the product into the shopping basket, the check mark box CHK in the shopping list is tapped to display a check mark. Or when a new product is added to the shopping list, a product included in the shopping list is deleted, or the guidance route NR needs to be changed due to the addition of these products. Is requested to the route navigation system 25.
The current position detection process is a process of making an inquiry to the position detection system 24 to acquire the current position of the cart 22 on which the self is mounted and displaying the cart current position mark 22N on the map screen.

FIG. 24 is an explanatory diagram illustrating an example of a display screen during shopping.
Thereafter, the display screen is gradually changed. For example, as shown in FIG. 24, the customer performs shopping according to the guide route NR, the cart 22 moves to the position indicated by the cart current position mark 22N, and the product name display field. By tapping the four check mark boxes CHK corresponding to CL1 to CL4, the check mark is displayed.

  On the other hand, if it is determined in step S16 that all the purchase target products have been acquired, a guidance process to the checkout station where the POS terminals constituting the POS system 21 are arranged is performed as part of the route guidance process ( Step S17).

  Then, a settlement process is performed on the purchased product by cash or credit payment by the customer (step S18), and the cart 22 is returned to the predetermined return position to perform the cart return process, and the correspondence between the cart 22 and the customer. Processing for canceling the relationship is performed (step S19).

  As described above, according to the present embodiment, the planned purchase product can be included in the shopping list as a pending state, and the planned purchase product placed in the pending state is excluded from the target of route guidance and total amount calculation, etc. Because you can register the product to be purchased like a handwritten shopping list, you will be guided to the display place of the product to be purchased that you really want to purchase, Products can be easily purchased with room for consideration.

  In the above description, the configuration is such that the generation of the guidance route is performed by the external route navigation system 25 in order to reduce the load on the shopping assist terminal device 23, but the shopping assist terminal device 23 has sufficient processing capability. If there is, it is possible to generate and set a guide route by the shopping assist terminal device 23.

In addition, the control program executed by the shopping assist terminal device 23 according to the present embodiment is a file in an installable format or an executable format, and is a CD-ROM, flexible disk (FD), CD-R, DVD (Digital Versatile Disk). And the like recorded on a computer-readable recording medium.
Moreover, you may comprise so that the control program run with the shopping assist terminal device 23 of this embodiment may be provided by storing on a computer connected to networks, such as the internet, and downloading via a network. Moreover, you may comprise so that the control program run with the shopping assistance terminal device 23 of this embodiment may be provided or distributed via networks, such as the internet.
