Description

  The present invention relates to a product selection support apparatus and a computer program that support online shopping by a customer via communication means such as the Internet.

Online shopping, which purchases products by accessing product provider sites (EC sites) that provide products, mainly through the Internet, has become very popular. However, in online shopping, even if it is a product that requires the selection of a desired size, such as clothes, shoes, hats, etc., as a matter of course, it is purchased after trying on as in general store sales. I can't say that. In online shopping, usually after checking the design of the product through the screen of the user terminal, the size information (S, M, L, etc.) displayed in characters is selected at the customer's own discretion and the product is purchased. It is. For this reason, customers may not be worried about whether the purchased product really fits their size until the product actually arrives and tries on. It is thought that it is more than the case of purchasing at store sales. In view of this point, Patent Document 1 proposes creating a virtual model of a customer from the photograph image information of the customer and causing the virtual model to perform a virtual fitting simulation. Moreover, in patent document 2, not only extracting the goods suitable for a customer's body type about a certain product, but the size of the item which a customer owns, and the customer's body type information are registered beforehand, and the owned item is It has been proposed that a coordinated product suitable for coordination is extracted with reference to item size and customer body information and presented to the customer.

  The present invention compares the customer body type information with the size information of the purchase target product selected from the product database, and evaluates the degree of conformity to the customer body type as the degree of comfort, and the user terminal Before receiving the purchase decision information, a comfort level transmitting unit capable of transmitting the comfort level of the purchase target product obtained by the comfort level evaluation unit to the user terminal is provided. Therefore, the customer can know the degree of comfort when the purchase target product is worn in the body shape of the customer, and can select and purchase a product having a desired comfort level from among them. For this reason, customers can choose the products that they want to purchase, such as those that are usually considered optimal for their body shape, those that are tight but highly fashionable, and items that can be worn loosely and comfortably. Products can be purchased, and online shopping in a form closer to that of try-on sales at an actual store becomes possible.

  Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a schematic diagram for explaining an outline of a product selection support apparatus 10 according to an embodiment of the present invention. The product selection support apparatus 10 is composed of an independent computer having a control means 11 such as a CPU, and is installed in a computer (product providing server) 300 of various product providers operating an EC site that provides online shopping. It is connected.

  A customer database (customer DB) 12 and a product database (product DB) 13 are formed in the storage unit of the computer constituting the product selection support apparatus 10. Also installed are a customer identification means 15, a comfort level evaluation means 16, a comfort level transmission means 17, a basic product information reception means 18, a coordinated product extraction means 19, etc., each comprising a computer program. These computer programs are provided by being stored in a recording medium such as a flexible disk, a hard disk, a CD-ROM, an MO (magneto-optical disk), a DVD-ROM or the like carrying a program that cannot occupy space by itself. It can also be transmitted to another computer through a communication line.

  It is preferable that the product selection support device 10 is provided at a rate of one for the plurality of product providing servers 300. Even if a customer performs shopping on a plurality of product providing servers 300, the product can be managed centrally by one product selection support device 10. In addition, when purchasing a coordinated product, the purchase history at the EC site provided by the plurality of product providing servers 300 can be referred to, and the coordinated product can be selected from the plurality of EC sites. It is possible to purchase new products. However, a configuration in which each product providing server 300 is also used as the product selection support device 10 by setting computer programs such as the databases 12 and 13 and the comfort level evaluation means 16 described above in each product providing server 300. It is good.

  As shown in FIG. 2, the customer database 12 includes customer attribute information such as name, address, gender, age, ID number for accessing the product providing server 300 for shopping, and a password for shopping. It is remembered. For each customer, the customer's body type information (customer body type information) is recorded. Specifically, height, chest circumference, waist circumference, waist circumference, body type classification, shoe size, and the like. Of course, these are only examples, and various body type information such as inseam and head size can be recorded. In addition, the body type division of FIG. 2 illustrates the body type division by JIS. Further, in the present embodiment, for each customer, information such as the purchase history (product number (product No.), purchase date, product detailed data (length, design, etc.)) of the customer in the past is also recorded. ing. The purchase history is set to be sequentially updated every time shopping is performed at any EC site.

  As shown in FIG. 3, the product database 13 includes a product number (product No.), a product category (product type), a price, a sales target age group (target layer), a stock quantity, etc. for each product. It is stipulated in. Further, for each product (product No.), information on the most suitable body shape when wearing the product (optimum body shape information), and not optimal, it is tight or loose comfort when worn. However, information on the body type within the allowable range that can be said to be suitable for wearing (compatible body type information) is defined as the size information. For example, product no. In the case of a 0001 blazer, the optimum body shape: “JY body shape” and the conforming body shape “height 165 to 175 cm, JY body shape” are defined. That is, when this product is worn, it will be the most appropriate comfort if it is worn by a person with a JY body shape (18 cm dimensional difference between the chest and the waist). When a person with a difference of 20 cm) wears it, the comfort is relaxed. On the other hand, when a person of Y body type (the dimensional difference between the chest and the waist is 16 cm) is worn, it becomes tight comfort. In this way, when it is not the optimal body shape, it is comfortable to relax and tight, but within the range of the compatible body shape, it is a range that can be worn according to preference. Therefore, for example, if the customer type information is Y type customer No. In the case of 0003 "Jojiro" (male, 30 years old), the optimal body type "Y body type" is the best, but if you want a tailored blazer, the optimal body type is "JY body type" and fits Product No. containing “Y body shape” in the body shape. A blazer of 0001 or 0002 is selected as a candidate for purchase.

  The customer specifying unit 15 acquires information for specifying a customer such as a customer ID and a password when the customer accesses one of the EC sites (the product providing server 300) by operating the user terminal 200.

  The comfort level evaluation unit 16 compares the size information of the purchase target product selected from the product database 13 and evaluates the degree of conformity to the customer body shape as the comfort level. One or more items to be purchased are selected by the customer. The comfort level evaluation means 16 collates the customer body information of the customer read from the customer database 12 with the optimum body shape information and conforming body shape information of the selected purchase target product, and “optimum”, “ Evaluate the degree of comfort such as “tight” and “relaxing”. For example, “optimal” indicates that the customer's body shape information matches the optimal body shape of the product, and “tight” indicates that the product size is within the range of the conforming body shape than the customer's body shape information. In the case of slimming in several stages (for example, one stage) by JIS body type classification rather than the optimal body type, “Loose-meat” means that the size of the product is within the range of its conforming body type, rather than the customer's body type information. The degree of comfort can be defined as in the case of several stages (for example, one stage) larger than the body type in JIS body type classification.

  The comfort level transmission means 17 transmits the comfort level evaluated by the comfort level evaluation means 16 to the user terminal 200. More specifically, the information is transmitted via the product provision server 300 accessed by the user terminal 200. Since it is generally considered that the customer uses the degree of comfort as reference information when finally making a purchase decision on a product, at a timing before the customer transmits purchase decision information from the user terminal 200, It is desirable to set to transmit to the user terminal 200 so that the degree of comfort can be viewed.

  The basic product information receiving means 18 is the product category of the basic product that is the basis of coordination and the characteristics of the product when the customer intends to purchase a product (coordinated product) suitable for coordinating with a certain product (basic product). Receive. A certain product (basic product) may be a product already owned by a customer or a product to be purchased from now on.

  The coordinated product extraction means 19 extracts coordinated products suitable for coordinating with the basic product from the product database 13 based on the product category and product characteristics of the basic product. For example, in the product database 13, the product No. With regard to the “blazer” of 0001, a product suitable for coordinating with this product is registered in advance as a coordinated product. As a result, the product No. When the “0001” blazer is selected, the corresponding coordinated product is extracted. Also, instead of associating the gorgeous product with each product in advance, select the product category of the basic product and the category of the desired coordinated product, and refer to the customer attributes and body information from among them to coordinate the product It can also be a program in which For example, if the category of the basic product is “blazer” and the category of the coordinated product desired to be coordinated is “shirt”, the customer attribute and body information of the customer are referred to from the “shirt” of the product database 13. The coordinated product that is the final candidate is extracted.

  Next, an online shopping method using this embodiment will be described with reference to FIG. Here, a case where a customer purchases a coordinated product, not a case where a customer purchases a single product, will be described as an example. First, a customer accesses an EC site of a product provider server 300 of a product provider and logs in using a customer ID, a password, and the like (S101, S102). This log-in information (information such as customer ID and password) is transmitted from the product providing server 300 of the EC site to the product selection support device 10 of the present embodiment. The customer is received and the customer is specified (S103).

  When a customer purchases a coordinated product instead of purchasing a single product, information desired to perform a simulation for selecting the coordinated product is transmitted from the user terminal 200 (S104). Next, the customer selects a product as a basis for the simulation, that is, a category of a basic product for coordination and a category of a coordinated product desired to be purchased (S105). The customer selection information is received by the basic product information receiving means 18.

  When the basic merchandise information receiving means 18 receives the selection information of the customer, the coordinated product extracting means 19 is operated, and based on the customer information specified by the customer specifying means 15, the customer attribute of the customer, The body type information and purchase history are read (S106). Then, in the purchase history, it is determined whether or not a product category related to the basic product designated by the customer exists (S107).

  If there is a product category related to the basic product specified by the customer in the purchase history, the product with purchase history and the unpurchased product corresponding to the product category of the basic product are extracted from the product database 13 Then, it is transmitted to the user terminal 200 (S108). On the other hand, if there is no product category related to the basic product in the purchase history, an unpurchased product corresponding to the product category of the basic product is extracted from the product database 13 and transmitted to the user terminal 200 (S109). ).

  The customer selects a specific product as a basis for the simulation from the products transmitted in S108 or S109 (S110).

  The coordinated product extraction means 19 narrows down the products to be purchased from the categories of coordinated products selected by the customer for purchase in S105 based on the customer attributes and body shape information (S111). As a result, products that clearly deviate from customer attributes, products that do not match the body shape information, and the like are excluded from the purchase target products.

  Next, the comfort level evaluation means 16 operates and evaluates the comfort level of the coordinated product remaining as the purchase target product. Specifically, as described above, the customer body type information of the customer is collated, and the degree of comfort such as “optimal”, “tight”, “relaxed” is evaluated (S112). The evaluation results are arranged by the comfort level transmission means 17 together with the information of each coordinated product extracted, for example, in order of high comfort level or low level, and as site information unique to each customer, the product providing server It is transmitted to the user terminal 200 via 300 (S113, S114).

  After browsing the received information, the customer further inputs characteristics of the product, for example, characteristics such as “chic clothing” and “spring-like clothing” (S115). When the feature of the product is received by the basic product information receiving means 18, the coordinated product extraction means 19 refers to this, further narrows down the above-mentioned coordinated product candidates, and these information is received as site information unique to each customer. It is transmitted again to the user terminal 200 by the comfort level transmission means 17 (S116, S117). After that, the customer refers to this site information, considers the degree of comfort and characteristics of the product, determines the product to be actually purchased from one of the extracted coordinated products, and supports the purchase selection information for product selection Transmit to device 10. In this embodiment, not only the size display of “S, M, L” is defined for each product, but also the optimum body type information and the conforming body type information are defined. You can know how you feel when you wear them with your body type by referring to “Degree of comfort”. For this reason, according to this embodiment, online shopping in a form very close to the case of trying on and purchasing a product at an actual store becomes possible.

  FIG. 5 shows an example of site information unique to each customer transmitted by the comfort level transmission means 17 in S116 and S117. In this example, the coordinated basic product and the coordinated product that is the purchase target product and the size are displayed, and the image quality information that combines the basic product and each coordinated product is displayed as “coordinate information” by the comfort level transmission means 17. Creating. The comfort level transmission means 17 has a function of creating a virtual model based on the customer body type information, and displays the virtual model by wearing the basic product and the coordinated product that is the purchase target product. Thereby, it is preferable to use such a virtual model because the appearance image when those products are actually worn is well understood and approaches the purchase form in an actual store. In addition, when using the virtual model, it is not essential to have the basic product be worn by the virtual model, and it is sufficient that at least the function of causing the purchase target product to be worn, but if the purchase target product is a coordinated product, It is preferable to wear it together with the basic product as described above.

  Here, in the aspect shown in FIG. 4, in S111, coordinated products are extracted based on customer attributes and body type information, and the comfort level is evaluated in S112 for the extracted coordinated products, and then the customer desires. Although further narrowing down is performed using the product features, the comfort level and the product features may be added to the conditions when the coordinated products are first narrowed down. FIG. 6 is a flowchart showing the online shopping process in that case. The process (S101 to S110) from when the user terminal 200 logs into one of the EC sites to select a product to be the basis of the simulation is the same as that shown in FIG. In step S201, the degree of comfort and the feature of the product are selected.

  The comfort level is set in three stages, for example, “optimum”, “tight”, and “relaxed”, and the customer selects a desired comfort level of the product from the user terminal 200 Then send. Further, in this embodiment, in S201, along with the degree of comfort, the characteristics of the product, for example, “chic clothing”, “spring-like clothing”, and the like are selected and transmitted.

  When the product selection support apparatus 10 receives the information on the comfort level and the product characteristics, the coordinated product extraction unit 19 firstly coordinates the purchase target based on the customer's attribute information, body information, and product characteristics. Product candidates are extracted (S202). Next, with respect to the extracted products, the size information and the customer's body shape information are compared to calculate the comfort level, and the product with the desired comfort level is extracted from the list in S201 (S203). ). The extracted product information is transmitted to the user terminal 200 as customer-specific site information (S204, S205), but these products are only products having the degree of comfort desired by the customer. In the mode shown in FIG. 4, information on purchase target products having various comfort levels within a range that can be worn by the customer is transmitted to the user terminal 200, and the customer selects a comfort level desired by the customer. In this aspect, when sending information on the purchase target product to the customer, the customer is already limited to the comfort level desired by the customer, so the customer narrows down the final purchase target product more quickly. be able to. Thereafter, similarly to the mode shown in FIG. 4, when the customer purchases any coordinated product, the purchase decision information is transmitted and purchased, and when the customer does not purchase, the process ends.

  In the above description, the process of online shopping is described by taking the case of purchasing a coordinated product as an example. However, the point of performing online shopping using the evaluation information of the comfort level is when purchasing a single product. The same applies to. In addition, the object to be coordinated is not limited to clothing, and it is a matter of course that various products such as footwear, various accessories, bags, daily necessities, figurines, furniture, and the like can be targeted.
