Description

  The present invention relates to a shopping system.

  2. Description of the Related Art In recent years, efforts to connect services on the Internet (Oline), called O2O (Online to Offline) or Offline to Online, to attract customers and promote purchases in actual stores (Offline) have become active.

  One example of a service that incorporates the O2O concept is one that uses a smartphone application. In the service, for example, a dedicated application for the service is downloaded to a smartphone in advance, and when the user enters a commercial facility that provides the service, the position sensor of the smartphone recognizes the position of the user, and the product in the actual store Services such as real-time distribution of information and electronic coupons to dedicated applications are conceivable.

  Non-Patent Document 1 below introduces an example of O2O service. In the service, a product image and a QR code are displayed on a poster installed in a subway station, and when the user reads the QR code using a smartphone, the smartphone requests a shopping site to order the product. Send. When the user settles the product on the shopping site, the product is delivered to the user's home.

  In the O2O service described in Non-Patent Document 1, a user reads a QR code posted on a poster in order to select a product to purchase. However, in order to actually purchase the product, it is necessary to confirm the purchase on the smartphone, which is substantially the same as the case where the product selection act on the conventional electronic commerce site is replaced with the act of reading the QR code. That is, it can be considered that the means for selecting a product is merely replaced with a QR code. Moreover, in this service, it is necessary for the user to use a smartphone only for the purpose of selecting a product, which impairs convenience.

  The present invention has been made in view of the above problems, and in an O2O service for shopping purposes, a plurality of items that can be selected and settled by a user without degrading the convenience of the user. It aims at providing the means of.

  The shopping system according to the present invention has a display input device installed in a space through which an unspecified number of persons pass, and is selected on the display input device between the display input device and another operation terminal. Share information about sold products.

  According to the shopping system according to the present invention, the user can select a product to be purchased on the display input device even if the user does not carry a terminal such as a smartphone. In addition, even if you want to hold the selection before finalizing the purchase, the information about the product selected on the display input device will be shared by the operation terminal. You can hold the selection until you do.

<Embodiment 1>
FIG. 1 is a configuration diagram of a shopping system 1000 according to Embodiment 1 of the present invention. The shopping system 1000 is a system that provides an O 2 O shopping service to the user 402, and includes a display input device 100, a server 200, and a database 300. These devices are connected via a network 500 such as the Internet.

  The display input device 100 is configured using, for example, a touch panel display, and displays information such as images, prices, and product names of products purchased by the user 402 on the screen. The user can select a product on the screen of the display input device 100. When the user 402 selects a product on the screen, an image as if the product has moved is displayed in the shopping cart 101 displayed on the screen. The display input device 100 is installed in a space through which a plurality of unspecified persons can pass. For example, a commercial facility, a station premises, along a street, etc. can be considered as the installation location. A device other than the touch panel display can be used as long as information can be displayed and selected.

  The server 200 is a computer that implements processing related to shopping. For example, information such as a product image, a price, and a product name is transmitted to the display input device 100, and selection data 320 describing selection contents of the product selected on the display input device 100 by the user 402 is received and the database 300. To store. Further, the product selected by the user 402 described in the selection data 320 is settled by a predetermined settlement means. Since these functions are functions realized by a known electronic commerce site, details will not be described.

  The server 200 includes an authentication unit 210 that authenticates the user 402. The authentication unit 210 authenticates the user 402 using the user data 310 stored in the database 300. A specific example of the user data 310 will be described later.

  The server 200 further includes a tracking unit 220. When the user 402 is moving near the display surface of the display input device 100, the tracking unit 220 tracks the position of the user 402 and specifies the position in real time (or a time interval close thereto).

  The camera 401 captures the vicinity of the display surface of the display input device 100 and transmits the captured image to the server 200. The authentication unit 210 and the tracking unit 220 authenticate the user 402 using the captured image received from the camera 401 or specify the position thereof. Details will be described later.

  The selection data 320 can also describe whether or not the product has been settled together with a description of the product selected by the user 402. Alternatively, the settled product may be deleted from the selection data 320. In the following, for the sake of simplicity, the latter is assumed.

  The authentication unit 210 and the tracking unit 220 may be implemented by using hardware such as a circuit device that realizes the function, or by an arithmetic device such as a CPU (Central Processing Unit) and software that defines the operation thereof. May be. The database 300 can be configured by storing data files in a storage device such as a hard disk device.

  FIG. 2 is a diagram showing details of the user data 310. User data 310 is data describing attribute information of the user 402, and includes a user ID 311, authentication data 312, payment means data 313, and position data 314.

  The user ID 311 is an ID unique to the user 402. The authentication data 312 is data describing authentication information used when the authentication unit 210 authenticates the user 402. For example, when using face authentication, the face image of the user 402 is registered in advance as authentication data 312. When there is a possibility that the user 402 uses an operation terminal other than the display input device 100, authentication information (for example, a password) for the terminal is also registered. The settlement means data 313 is data describing information about a means (for example, a credit card number) used when making a purchase settlement of the product selected by the user 402. The position data 314 is data describing the current position (for example, relative coordinates with respect to the display input device 100) of the user 402 specified by the tracking unit 220.

  FIG. 3A is a diagram for explaining the operation of each device when the user 402 approaches the display input device 100. Hereinafter, each step of FIG. 3A will be described. As a premise, it is assumed that information on the ID, face image, and settlement method of the user 402 has been registered in each field in the user data 310 in advance.

(FIG. 3A: (1) Shooting to (2) Face image transmission)
When the user 402 approaches the vicinity of the display surface of the display input device 100, the camera 401 captures a face image of the user 402. The camera 401 transmits an image near the display surface of the display input device 100 including the face image to the server 200. Alternatively, the authentication unit 210 may periodically request the camera 401 to transmit a face image, and the camera 401 may transmit the face image accordingly.

(FIG. 3A: (3) Face authentication)
The authentication unit 210 compares the face image acquired from the camera 401 with the authentication data 312 in the user data 310. If there is a matching face image, the authentication unit 210 identifies the user ID 311 corresponding to the face image as an ID unique to the user 402. Furthermore, the tracking unit 220 specifies the relative position of the user 402 with respect to the display input device 100 based on the image received from the camera 401 and stores it as position data 314.

(Fig. 3A: (4) ID transmission)
For example, the display input device 100 periodically requests information such as product images, prices, and product names from the server 200 and displays the information received from the server 200 on the screen. When there is a user ID 311 specified by face authentication when the authentication unit 210 responds to the request from the display input device 100, the authentication unit 210 sends the ID to the display input device 100 together with a reply to the request. Send.

(Figure 3A: (5) Cart display)
The display input device 100 receives the ID of the user 402 from the server 200 and stores it as a screen component. This ID is not necessarily visible to the user 402. Thereafter, when the display input device 100 requests a product image or the like from the server 200, the display input device 100 transmits the ID of the user 402 together with the request, and requests the position data 314 corresponding to the ID. The tracking unit 220 returns position data 314 in response to the request. When the acquired position data 314 is within a predetermined range (for example, within 30 cm) from the display surface of the display input apparatus 100, the display input device 100 displays the shopping cart 101 on the screen at a position corresponding to the position data 314.

  FIG. 3B is a diagram illustrating the operation of each device when the user 402 selects a product on the display input device 100. FIG. 3B is a continuation of the operation described in FIG. 3A. Hereinafter, each step of FIG. 3B will be described.

(Fig. 3B: (6) selection)
The user 402 selects one of the products on the screen of the display input device 100. For example, if the display input device 100 is a touch panel display, the product image to be selected is dragged and dropped onto the shopping cart 101. Or you may provide a selection button for every goods like a general web page.

(FIG. 3B: (7) ID + selected data transmission)
The display input device 100 selects which product the user 402 has selected along with the ID of the user 402 at the timing of periodically requesting a product image or the like from the server 200 or when the above-described selection button is pressed. Send selection data that describes

(FIG. 3B: (8) Selection data storage to (9) ID + selection data transmission)
The server 200 associates the selection data received from the display input device 100 with the ID of the user 402 and stores it as selection data 320. The server 200 returns the ID of the user 402 and the selection data 320 together with a response to the request for the product image.

(Figure 3B: (10) Cart display)
When the display input device 100 displays the shopping cart 101 on the screen and the selection data 320 received from the server 200 exists, the product described by the selection data 320 is put into the shopping cart 101. An image showing the situation is displayed on the screen.

  FIG. 3C is a diagram for explaining the operation of each device when the user 402 moves in the vicinity of the display surface of the display input device 100. FIG. 3C is a continuation of the operation described in FIG. 3A or 3B. Hereinafter, each step of FIG. 3C will be described.

(FIG. 3C: (11) Shooting to (14) Face tracking)
The camera 401 continuously photographs the vicinity of the display surface of the display input device 100. The authentication unit 210 authenticates the user 402 by continuously performing the same operation as described in FIG. 3A. The tracking unit 220 identifies the position of the user 402 based on the image received from the camera 401 and updates the position data 314.

(FIG. 3C: (15) ID + selected data transmission)
The server 200 returns the ID of the user 402 and the selection data 320 in response to a periodic request for a product image or the like from the display input device 100. This step is the same as step (9).

(Figure 3C: (16) Cart display)
The display input device 100 displays the shopping cart 101 on the screen at a position corresponding to the updated position data 314. When the selection data 320 exists, the product corresponding to the selection content is displayed in the shopping cart 101 together. This step is a combination of steps (5) and (10).

  FIG. 3D is a diagram for explaining the operation of each device when the user 402 confirms an order for a product on the display input device 100. FIG. 3D is a continuation of the operation described in FIG. 3B or 3C. Hereinafter, each step of FIG. 3D will be described.

(Fig. 3D: (17) Order input)
The user 402 inputs on the screen of the display input device 100 that the order for the product currently put in the shopping cart 101 is confirmed. For example, this can be input by pressing an order confirmation button on the display input device 100.

(FIG. 3D: (18) Ordering instruction transmission to (19) Settlement)
The display input device 100 instructs the server 200 to place an order for the product described in the current selection data 320. The server 200 orders the contents of the selection data 320 according to the instruction, and settles according to the description of the settlement means data 313. The server 200 deletes the record in the selection data 320 for which payment has been completed (or writes information indicating that payment has been completed in the record).

  FIG. 3E is a diagram for explaining the operation of each device when the user 402 confirms an order for a product on an operation terminal other than the display input device 100. FIG. 3E follows the operation described in FIG. 3B or 3C. It is assumed that the user 402 has the user terminal 403 as an operation terminal. Hereinafter, each step of FIG. 3E will be described.

(Fig. 3E: (17) Leave ~ (18) ID + selection data transmission)
The user 402 moves away from the vicinity of the display surface of the display input device 100 with the merchandise being put in the shopping cart 101. As a result, the camera 401 cannot capture the face image of the user 402. The display input device 100 transmits the ID of the user 402 and the selection data 320 to the server 200 at a timing at which a product image or the like is periodically requested from the server 200.

(FIG. 3E: (19) Face authentication to (20) Face tracking)
The authentication unit 210 and the tracking unit 220 authenticate the user 402 using the face image as in step (3), and specify the position of the user 402. Since the user 402 has already moved outside the imaging range of the camera 401, authentication and tracking will fail in this step. Even if the user 402 exists within the shooting range of the camera 401, if the user 402 moves outside the predetermined range described with reference to FIG. 3A (5), it is similarly treated that authentication and tracking have failed. You can also.

(FIG. 3E: (21) ID + selection data not transmitted)
When the authentication and face tracking by the authentication unit 210 and the tracking unit 220 fail, the server 200 does not transmit the ID of the user 402 or the selection data 320 to the display input device 100. Therefore, the display input device 100 receives only the product image excluding these pieces of information as a response to the request for the product image.

(Figure 3E: (22) Cart erase)
When the display input device 100 does not receive the ID of the user 402 from the server 200, the display input device 100 deletes the shopping cart 101 from the screen.

(Figure 3E: (23) Login)
The user 402 logs in to the server 200 using the user terminal 403. At this stage, since face authentication using the camera 401 cannot be performed, the authentication unit 210 authenticates the user 402 by checking the ID and password of the user 402 with the authentication data 312, for example. When the user terminal 403 issues a login request, the user terminal 403 also requests to transmit selection data 320 corresponding to the user 402.

(FIG. 3E: (24) Select data transmission to (25) Settlement)
When the server 200 is successfully authenticated, the server 200 reads the selection data 320 corresponding to the ID of the user 402 and transmits it to the user terminal 403. The user 402 confirms the contents of the selection data 320 on the user terminal 403, and then transmits an ordering instruction similar to step (18) to the server 200. The server 200 performs settlement in the same manner as in step (19).

<Embodiment 1: Summary>
As described above, the shopping system 1000 according to the first embodiment includes the display input device 100 installed in a space through which an unspecified number of people pass, and the user 402 uses the display input device 100 to purchase a product that the user wants to purchase. You can choose. Thereby, the user 402 can select a product to be purchased without using a terminal such as a smartphone as in Non-Patent Document 1.

  Further, the shopping system 1000 according to the first embodiment shares selection data 320 describing a product selected by the user 402 on the display input device 100 between the display input device 100 and the user terminal 403. As a result, the user 402 can select and settle a product via a plurality of terminals. For example, a product can be selected once on the display input device 100, and whether or not the purchase is finally decided can be decided later on the user terminal 403.

  In the shopping system 1000 according to the first embodiment, the display input device 100 moves the shopping cart 101 following the movement of the user 402. As a result, the user 402 can experience a shopping experience on the display input device 100.

<Embodiment 2>
In the first embodiment, the configuration example in which the selection data 320 is transferred from the display input device 100 to another operation terminal (the user terminal 403 in the first embodiment) has been described. In the second embodiment of the present invention, a configuration example using another display input device as another operation terminal will be described. Except for using another display / input device as the operation terminal, it is substantially the same as in the first embodiment, and therefore, the following description will be focused on the differences.

  FIG. 4 is a configuration diagram of the shopping system 1000 according to the second embodiment. A shopping system 1000 according to the second embodiment includes two display input devices 100 having equivalent functions. In the following, the subscripts a and b are used to distinguish between these, and the display input devices 100a and 100b are used. The same applies to the camera 401. It is assumed that the display input devices 100a and 100b and the cameras 401a and 401b are installed at relatively close locations such as in the same facility.

  FIG. 5 is a diagram for explaining the operation of each device when the user 402 moves from the front of the display input device 100a to the front of the display input device 100b. As a premise of FIG. 5, it is assumed that the user 402 has already performed the operation described in FIG. 3B (a product has been selected on the display input device 100a). Hereinafter, each step of FIG. 5 will be described.

(Figure 5: (26) Move)
The user 402 selects a product on the display input device 100a and then moves in front of the display input device 100b. As a result, the user 402 moves out of an area within a predetermined range (for example, within 30 cm) from the display surface of the display input device 100a, and further moves out of the imaging range of the camera 401a.

(FIG. 5: (27) ID + selection data transmission to (29) face tracking)
The display input device 100a transmits the ID and selection data of the user 402 at the timing of periodically requesting a product image or the like from the server 200. The authentication unit 210 authenticates the user 402 using an image captured by the camera 401a. Here, since the user 402 does not exist in the image, the authentication fails. The tracking unit 220 reflects in the position data 314 that the user 402 has left the front of the display input device 100a.

(FIG. 5: (30) ID + selection data not transmitted to (31) cart erase)
Since the server 200 has failed to authenticate the user 402 by the authentication unit 210, the server 200 does not transmit the ID of the user 402 to the display input device 100a. Since the display input device 100a has not received the ID of the user 402 from the server 200, the display input device 100a deletes the shopping cart 101 from the screen. That is, since the position data 314 corresponding to the ID of the user 402 cannot be obtained, the shopping cart 101 is deleted.

(Figure 5: (32) Shooting to (36) Cart display)
The camera 401b photographs the user 402 that has moved in front of the display input device 100b. Thereafter, the display input device 100b and the server 200 perform the same operation as in FIG. 3A, and the shopping cart 101 is displayed on the display input device 100b. However, in FIG. 5, since selection data 320 describing a product selected by the user 402 on the display input device 100 a is stored on the server 200, the server 200 transmits this together with the ID of the user 402. The display input device 100b displays an image that appears as if the product corresponding to the received selection data 320 has been put into the shopping cart 101. Subsequent operations are the same as those in the first embodiment. That is, the user 402 may make a payment on the display input device 100b or may make a payment on the user terminal 403.

<Embodiment 2: Summary>
As described above, the shopping system 1000 according to the second embodiment includes the display input devices 100a and 100b having the same functions, and the selection data 320 is shared between these devices. As a result, the user 402 can select and settle a product via the plurality of display input devices 100. In addition, it is possible to cope with a case where not all products can fit in the screen of the single display input device 100.

  In addition, since the shopping system 1000 according to the second embodiment shares the selection data 320 between the display input devices 100a and 100b using the ID of the user 402 as a key, the user ID 311 and the selection data 320 are appropriately linked. Can do.

<Embodiment 3>
In the first and second embodiments, the configuration example in which the user 402 is authenticated and tracked using the camera 401 has been described. The means for authenticating and tracking the user 402 is not limited to the camera 401, and it is sufficient that a function similar to this can be realized. In the third embodiment of the present invention, as an example, a configuration example in which the user terminal 403 is used to authenticate and track the user 402 will be described.

  FIG. 6 is a configuration diagram of the shopping system 1000 according to the third embodiment. A shopping system 1000 according to the third embodiment includes a terminal sensor 404 instead of the camera 401.

  The terminal sensor 404 is a sensor that can read a terminal ID unique to the user terminal 403. The authentication unit 210 authenticates the user 402 by acquiring the terminal ID read by the terminal sensor 404 and associating it with the ID of the user 402. The association between the two may be stored in advance as, for example, authentication data 312.

  The terminal sensor 404 can further measure the position of the user terminal 403, for example, by measuring the distance between the terminal sensor 404 and the user terminal 403. The tracking unit 220 acquires the position of the user 402 measured by the terminal sensor 404 and stores this in the user data 310 as position data 314. When only the relative positional relationship between the terminal sensor 404 and the user terminal 403 is known, the position of the user terminal 403 may be calculated in consideration of the installation position of the terminal sensor 404. Further, a plurality of terminal sensors 404 may be used in combination as necessary.

  In the third embodiment, the camera 401 and the terminal sensor 404 may be used in combination. In this case, for example, it is conceivable to prioritize the authentication / tracking result by either one, and adopt the authentication / tracking result by the other when this cannot be obtained. Alternatively, a method of determining a threshold value by weighting and adding the authentication / tracking results of both is also conceivable.

<Embodiment 4>
In the first to third embodiments, the display input device 100 does not have a function of authenticating and tracking the user 402, and the server 200 has the function. Instead of this, the display input device 100 may have the function. In the fourth embodiment of the present invention, an example will be described. Other configurations are the same as those in the first to third embodiments.

  FIG. 7 is a configuration diagram of the shopping system 1000 according to the fourth embodiment. In the fourth embodiment, the display input device 100 includes an authentication unit 102 and a tracking unit 103 having the same functions as the authentication unit 210 and the tracking unit 220. Along with this, a storage device (not shown) for storing the user ID 311 and the authentication data 312 is provided.

  In the fourth embodiment, since the display input device 100 can authenticate and track the user 402 by itself, the server 200 does not need to communicate with the camera 401 or the display input device 100 in order to implement this. However, when the user 402 pays for a product or when the selection data 320 is transferred to another operation terminal, it is necessary to transmit the ID of the user 402 and the selection data 320 from the display input device 100 to the server 200. Furthermore, at that time, the server 200 needs to perform user authentication in order to identify the user 402. Therefore, also in the fourth embodiment, the server 200 includes the authentication unit 210.

<Embodiment 5>
FIG. 8 is a diagram illustrating an operation example of the shopping system 1000 according to the fifth embodiment of the present invention. When there are a plurality of users 402 in front of the display surface of the display input device 100 described in the first to fourth embodiments, the display input device 100 can also display the shopping cart 101 on the screen for each user 402.

  In FIG. 8, the camera 401 captures images including the faces of the users 402a and 402b. The authentication unit 210 extracts a face image of each user from the image by face recognition, and authenticates each user by collating with the authentication data 312. The tracking unit 220 stores the position of each user as position data 314. The server 200 transmits the ID of each user to the display input device 100.

  When receiving the ID of each user, the display input device 100 acquires the corresponding position data 314 from the server 200 using the ID as a key. The display input device 100 displays the shopping cart 101 for each acquired position data 314 on the screen. Thereby, the shopping cart 101 can be provided to each of a plurality of users.

  The operation described in the fifth embodiment can be applied to other embodiments. For example, in the third embodiment, the terminal sensor 404 individually reads the terminal ID of the user terminal 403 possessed by each user, and the same processing may be performed for each terminal ID. Similarly in the fourth embodiment, the authentication unit 102 and the tracking unit 103 may specify the ID for each user 402 and perform the same processing.
