  Hereinafter, a purchasing behavior collection system according to an embodiment of the present invention will be described with reference to the drawings. In all the drawings for explaining the embodiments, common constituent elements are denoted by the same reference numerals, and repeated explanation is omitted.

FIG. 1 shows an example of the configuration of a purchasing behavior collection system 101 according to an embodiment of the present invention.
The purchase behavior collection system 101 includes a product database (DB) 102 in which product information is stored, a product category DB 103 in which product category information indicating product categories displayed in each area in the store is stored, Purchasing behavior DB 104 storing purchasing behavior information indicating purchasing behavior and purchasing trend, purchasing behavior recording unit 106 that records purchasing behavior information in purchasing behavior database (DB) 104, and merchandise information that acquires product information from merchandise DB 102 From the acquisition unit 107, the location information acquisition unit 108 that obtains the location information of the mobile device 111 using the information acquired from the mobile device 111, and the purchase behavior display unit 110 that searches the purchase behavior DB 104 and displays the purchase behavior. Composed.

Each function of the purchase behavior recording unit 106, the product information acquisition unit 107, the location information acquisition unit 108, and the purchase behavior display unit 109 constituting the purchase behavior collection system 101 includes a CPU (Central Processing Unit) and a RAM (Random). This is realized by the CPU executing a purchase behavior collection program stored in the memory in a computer having a memory configured by (Access Memory) or the like and a storage device configured by a hard disk or the like. A product database (DB) 102, a product category DB 103, a purchase behavior DB 104, and an APDB 105 are stored in a storage device of the computer.
Further, the CPU of the computer executes a self-service shopping execution program stored in the memory, so that the self-service in a form that does not use a shopping cart using the mobile device 111 that is not related to the collection of purchase behavior information. Although the function of the system related to shopping (self-service shopping execution unit 110) is realized, the object of the present invention is collection of purchase behavior information in a form that does not use a shopping cart using the mobile device 111. Description of the shopping execution unit 110 is omitted.

The mobile device 111 can communicate with a wireless LAN access point (AP) 112 wirelessly, and is a product purchase means in the customer's store. The mobile device 111 corresponds to, for example, a smartphone or a tablet terminal as means for transmitting customer purchase behavior information to the purchase behavior collection system 101.
The mobile device 111 measures the radio field intensity from the wireless LAN access point (AP) 112 installed in the store, and transmits the measured radio field intensity to the purchase behavior collection system 101.
A computer that realizes the functions of the purchase behavior collection system 101 and the self-service shopping execution unit 110 and a wireless LAN access point (AP) 112 are connected to a network 113, and the computer and the mobile device 111 communicate with each other. can do.

The measurement of the radio wave intensity is performed using the function of the mobile device 111 and is performed for all the APs 112 in the store that can be measured. Communication with the purchase behavior collection system 101 is performed in order to record customer purchase behavior, and communication is performed via the AP 112 set in the mobile device 111.

FIG. 3 shows an example of the configuration of purchase behavior information stored in the purchase behavior DB 104.
As shown in FIG. 3, the purchase behavior information includes customer ID (customer identification information) 301, time 302, coordinate x303, coordinate y304, product ID (product identification information) 305, product category ID (product category identification information) 306, And a purchase action type 307.
The customer ID 301 only needs to be able to uniquely identify a series of purchase behaviors from when the customer starts shopping to when it ends, and does not need to be able to identify an individual. That is, even when the same person comes to shop multiple times, the recorded customer IDs 301 need not have the same value. Based on the IP address For example the mobile device 111 is included in the information to be transmitted, the same customer ID301 into a series of purchase behavior until app (buying behavior collection program) is completed (settlement) after being activated Is granted. When the mobile device 111 transmits information to the purchase behavior collection system 101 when the application is activated, the purchase behavior recording unit 106 assigns a customer ID 301 and uses the customer ID 301 for a series of purchase behaviors until payment is made.
Time 302 is information on the time when the position coordinates are acquired. The time 302 is used when the flow line information is displayed later.
The coordinates x303 and the coordinates 3904 are the position coordinates of the mobile device 111 to which the customer ID 301 is attached at the time 302.
The product ID 305 is an ID for specifying a product. The product ID 305 is used to indicate which product the recorded purchase behavior is related to. Specifically, the corresponding product ID is recorded when acquisition of product information such as the price of the product, purchase determination of the product, and cancellation of the product are performed. In the purchase behavior information recorded at regular intervals, the product ID 305 does not exist or a value indicating that it does not exist is stored.
The product category ID 306 stores a product category ID related to the calculated position information.
The purchase behavior type 307 is information indicating what the purchase behavior information is recorded in the purchase behavior DB 104 as a trigger. There are five types of purchase behavior types 307: “product information acquisition”, “purchase decision”, “cancellation”, “settlement”, and “recording at regular intervals”. The purchase behavior information is recorded when any one of these purchase behaviors is performed.

FIG. 4 shows an example of the configuration of product information stored in the product DB 102. This data is used for the position coordinates when the product information is acquired.
The product ID (product identification information) 401 is an ID that can uniquely specify product information registered in the product DB 102. It is referred to when product information is acquired from the product DB 102.
The product name 402 is the name of the product.
Coordinate x403 and coordinate y404 are position coordinates of a place where the product is displayed. This is used for the position coordinate value of the purchase behavior information recorded when the purchase behavior for acquiring the product information is performed for price confirmation of the product.
The price 405 is the price of the product.
The stock 406 is the number of products in stock.

FIG. 5 shows an example of the configuration of product category information stored in the product category DB 103. This data is used for searching for a product category of a product displayed in an area in the store where the position coordinates are calculated when the position coordinates are calculated.
The product category ID (product category identification information) 501 is an ID that can uniquely identify the product category information registered in the product category DB 103.
The product category name 502 is the name of the product category.
The start point x503, the end point x504, the start point y505, and the end point y506 are values for determining which product category the position coordinates calculated by the position information acquisition unit 108 of the purchase behavior collection system 101 correspond to. When the calculated position coordinates are within a rectangular area with the four points of the start point (x503, y505), end point (x504, y506), point 3 (x503, y506), and point 4 (x504, y505) as vertices The product category ID 501 and the product category name 502 are regarded as being displayed at that position, and the product category ID 501 and / or the product category name 502 are searched.

Hereinafter, the case where the purchase behavior of the customer is recorded will be described in detail.
When the mobile device 111 transmits information to the purchase behavior collection system 101 when the application is activated, the purchase behavior recording unit 106 assigns a customer ID 301 based on an IP address included in the information transmitted by the mobile device 111, for example. The purchase behavior recording unit 106 uses the customer ID 301 for a series of purchase behaviors until the purchase behavior “settlement” is executed by the customer.

At this time, the purchase behavior recording unit 106 records, as a purchase behavior record, a customer ID, location information, a time when the location information is acquired, a product category ID, and purchase behavior type information indicating a record at regular intervals. The purchase behavior information that is included is recorded in the purchase behavior DB 104.
The automatic purchase behavior recording process is repeatedly executed at predetermined time intervals until the settlement process is performed after the application is activated.

FIG. 12 is a flowchart illustrating an example of processing performed when position information is acquired in steps S706, S806, S909, S1002, and S1102. This flow is carried out when the purchase action of “purchase decision”, “cancel”, “settlement”, and “record every certain time” is performed.
First, the location information acquisition unit 108 of the purchase behavior collection system 101 acquires time (S1201), and acquires a list of APs (wireless LAN access points) that can be observed at that time (S1201). Next, the position information acquisition unit 108 requests the mobile device 111 to measure the radio field intensity from each AP 112, and receives the radio field intensity from each AP 112 from the mobile device 111 (S1202).
Subsequently, the location information acquisition unit 108 confirms with respect to each AP 112 in the AP list whether the AP 112 is related to the purchase behavior collection system 101 registered in the APDB 105, and if it is registered in the APDB 105, the radio wave intensity is used. To measure the distance from the AP 112. If it is not registered in the APDB 105, the process is not performed and the process moves to the next AP in the AP list. The location information acquisition unit 108 executes the above processing for all the APs 112 in the AP list (S1203).
The position information acquisition unit 108 selects three APs 112 in ascending order of the distance values measured in step S1203, and acquires the coordinates of those APs 112 from the APDB 105 (S1204). Then, the position information acquisition unit 108 calculates the position coordinates of the mobile device 111 at the time when the radio wave intensity is acquired from the distance measured in step S1203 and the coordinates of the AP 112 acquired in step S1204. A specific calculation method will be described later (S1205).

  Furthermore, when the purchase action type is “recording at regular intervals” (S1206: Yes), the position information acquisition unit 108 acquires the product category information corresponding to the position coordinates from the product category DB 103 (S1207). Specifically, when the calculated position coordinates are included in the areas specified by the start point x503, end point x504, start point y505, and end point y506 stored in the product category DB 103, the position information acquisition unit 108 The product category ID corresponding to is acquired from the product category DB 103. The location information recorded in this process is not a purchase behavior record triggered by obtaining product information, etc., so it is not possible to determine the product that the customer is interested in, but the product corresponding to the position coordinates By preparing categories (frying pans, stuffed animals, etc.) in the merchandise category DB 103, merchandise information that the customer may be interested in can be recorded.

Next, a method in which the position coordinate calculation unit 109 of the purchase behavior collection system 101 calculates the coordinates of the mobile device 111 that has received the radio wave using the distance measured from the radio wave intensity of the AP 112 and the coordinates of the AP 112 will be described.
FIG. 13 shows an example of a figure that can be obtained by executing the process of FIG. The three APs 112 selected in step S1204 in FIG. 12 are used. Black circles represent the coordinates of each AP 112, and circles A, B, and C have a radius measured from the radio wave intensity.

  FIG. 14 is a diagram illustrating an example of an intersection used for calculation. As shown in FIG. 14, six intersection coordinates AB1, AB2, BC1, BC2, CA1, CA2 are obtained from three circles A, B, C. Intersection points AB1 and AB2 are obtained from the circles A and B, intersection points BC1 and BC2 are obtained from the circles B and C, and intersection points CA1 and CA2 are obtained from the circles C and A.

Subsequently, a point that is considered to be close to the position coordinates of the customer is calculated from the two points AB1 and AB2. FIG. 15 shows an example of a calculation image. FIG. 15A shows three circles A, B, and C, and FIG. 15B shows only the circle C.
A distance k1 between the intersection AB1 and the center of the circle C is obtained. When the radius of the circle C is r, the distance d1 from the intersection AB1 to the circumference is calculated from the following equation.
d1 = r−k1
The distance d2 from the intersection point AB2 to the circumference is similarly calculated. The absolute values of d1 and d2 are compared, and the intersection having a small value is used in the next calculation. Similarly, for the set of intersection points BC1 and BC2 and the set of intersection points CA1 and CA2, points that are considered to be close to the position coordinates of the customer are calculated. When the distance from the intersection point to the circumference becomes zero, the point is an intersection point of three circles. In this case, the position coordinate calculation unit 109 of the purchase behavior collection system 101 records the intersection of the three circles as the position coordinate of the customer at that time.

FIG. 16 shows an example of a calculation image when no intersection exists.
FIG. 16 is an example in the case where the measured radio field intensity is measured higher than the actual intensity. When the radio wave intensity is measured at a point where the radio waves from the two APs 112 overlap, the radio wave intensity may be measured higher than when the radio wave overlap does not occur. The closer the radio wave intensity is to the AP 112, the higher the radio wave intensity becomes. Therefore, when the radio wave intensity is measured higher, a shorter distance than the actual distance between the mobile device 111 and the AP 112 is measured.
In such a case, an intersection of a straight line passing through the center of the two circles and the circle is obtained. Among each intersection, the midpoint of the intersections close to the center of the other circle is obtained. This midpoint is used in the next calculation.
When two circles meet at one point, the next calculation is performed using that point.

FIG. 17 shows an example of a position coordinate calculation image. 17A shows three circles A, B, and C, and FIG. 17B shows a portion where the three circles A, B, and C overlap.
The points P1, P2, and P3 in FIG. 17 are obtained by the calculation described above. The center of gravity G of the triangle having the three points as vertices is obtained. The position coordinate calculation unit 109 of the purchase behavior collection system 101 records the coordinates of the center of gravity G as the position coordinates of the customer at that time.

  FIG. 18 shows an example of an image when determining whether the calculated position coordinates exist in the store or outside the store. For example, the position coordinates in the store are determined to be valid, and the position coordinates outside the store are determined to be invalid. By determining an effective range as the position coordinates in advance, the position coordinates can be deleted or the position coordinates can be corrected.

FIG. 19 shows an example of the flow of purchase behavior in the customer's store. FIG. 19A shows customer purchase behavior along with changes in customer position, and FIG. 19B shows customer purchase behavior in chronological order.
Since the customer needs to start the application (purchase behavior collection program) when entering the store, the purchase behavior information recorded first is when the app is started. A black circle in FIG. 19A represents a position when the purchase behavior information is collected at the time of starting the application and every predetermined time. A white circle represents a position when the product information is read from the shelf label and the purchase behavior information is recorded by the customer's mobile device 111. A white square represents a position when a customer performs purchase behavior for determining purchase and browses product information and adds the product to the shopping list, and purchase behavior information is recorded. A white triangle represents a position when a customer cancels a product on the shopping list and purchase behavior information is recorded. The black rhombus represents the position when the customer settles and purchase behavior information is recorded.

As shown in FIG. 19B, in this example, after the application is activated, the customer acquires the product information of the product 1, confirms the price, performs a purchase action to determine purchase, and adds the product 1 to the shopping list. ing. At time 1, there is a customer near the category A product shelf, but at the next time 2, the product information / category information is “None”. I understand that. From time 2 to time 7, the customer only moves. Between time 7 and time 8, the product information of the product 2 is acquired, the price is confirmed, a purchase action for determining purchase is performed, and the product 2 is added to the shopping list. From time 8 to time 10, it can be seen that the user was near the category B product shelf. Since the product price has not been confirmed, it can be seen that the customer was interested in the category B product but did not purchase it. Between time 11 and time 12, he was wondering whether to purchase product 3, but it did not result in purchase, but between time 12 and time 13, he purchased the product 1 but canceled whether to purchase product 4 or not. You can see that you are paying out.
The purchase behavior display unit 109 searches the purchase behavior DB 104 to show the purchase behavior of a specific customer along with the change in the position of the customer as shown in FIG. 19A, and as shown in FIG. Can be shown in series. Further, the purchase behavior display unit 109 can search the purchase behavior DB 104, analyze the purchase behaviors of a plurality of customers, and display the analyzed results.

  Since coordinates are recorded at regular intervals, customer traffic lines can be generated even at times when product information is not confirmed, and the customer is interested but has not been able to make a purchase with the touch or appearance. Even for a product for which product information has not been confirmed, the purchase behavior can be analyzed as a category in which the customer is interested.
