The storage unit 11 is a storage medium that stores data such as a hard disk or an SSD (solid state drive). The storage unit 11 stores a program for operating the control unit 12 and various data used by the control unit 12. The storage unit 11 includes, for example, a message DB 111, a character DB 112, and a user DB 113.

  FIG. 3 is an example of the message DB 111 stored in the storage unit 11. The message DB 111 corresponds to a first storage unit of the present invention, and stores a plurality of messages to be displayed on the user terminal 3 in association with product information about products to be introduced to customers using the user terminal 3 as shown in FIG. To do. The message may be stored for each product, or may be stored for a product category. As an example, when car A and car B exist, separate messages may be stored for both car A and car B, and a common message may be stored for the product category car. It is good as well.

  In the present embodiment, since the message is transmitted according to the character of the character desired by the customer, the message DB 111 stores the message in association with the character type of the character. The message DB 111 may store the same message in association with a plurality of characters corresponding to the same personality type.

  Moreover, message DB111 is good also as memorize | storing not only one but a several message with respect to the character of one goods and a character. In the example shown in FIG. 3, when a bearish female character introduces the product A, a plurality of messages such as messages A1, A2,.

  Next, FIG. 4 is an example of the character DB 112 stored in the storage unit 11. The character DB 112 corresponds to the second storage unit of the present invention, and stores information related to the face image of the character and information related to the character attribute for each character that transmits a message to the customer, as shown in FIG. The character attributes include, for example, at least a personality type in addition to the character name, gender, and age. The character attributes may include a profile of the character's virtual hobbies, occupations, etc. displayed when the customer selects the character. The face image is a still image or a moving image of the face of a two-dimensional or three-dimensional virtual character. Each character is provided with various variations of face images, and the character takes various expressions during the message exchange with the customer according to the content of the message and the character type of the character.

  Next, FIG. 5 is an example of the user DB 113 stored in the storage unit 11. The user DB 113 corresponds to the third storage unit of the present invention. As shown in FIG. 5, for each customer, customer attributes such as the customer's sex, age, and birthplace, the character selected by the customer, and the character And information on the selected character such as personality type.

It is good also as determining the customer who is likely to be interested as a customer introducing the product.
In addition, when the acquisition part 122 acquires goods information because a customer selects goods on a goods sales website, the determination part 123 is good also as determining the said customer as a customer who introduces goods.

When the acquisition unit 122 acquires the product information, the selection unit 124 selects at least one message corresponding to the character type of the character selected by the customer determined by the determination unit 123 from the plurality of messages associated with the product information. To do. When the customer has selected a plurality of characters, the selection unit 124 selects one character based on the product information acquired by the acquisition unit 122 and the attribute of the character among the plurality of characters before selecting a message. select. For example, when the product indicated by the product information is beer, the selection unit 124 selects a profile character that likes liquor.
The message transmission unit 125 transmits the message selected by the selection unit 124 to the user terminal 3 used by the customer in association with the face image of the character selected by the customer.

  Here, an example of the message transmitted by the message transmission unit 125 is shown in FIG. In FIG. 7A, the product “beer A” is introduced by the bearish female character “Yuka”. In FIG. 7B, the product “car B” is introduced by the bullish female character “Kaori”. As shown in FIG. 7, in the present embodiment, products are introduced while exchanging messages in a conversational form, instead of selling products with a single message. Such a conversational message can be realized by using a technique such as a so-called conversation bot that extracts a keyword from a customer message and returns a message corresponding to the extracted keyword.

Then, the structure of the assistant terminal 2, the user terminal 3, and the provider terminal 4 is demonstrated.
The operation reception unit 21 is a keyboard or a touch panel, for example, and receives an operation of an assistant. The assistant inputs a message via the operation reception unit 21. Note that the message input by the assistant is transmitted to the customer as necessary (see the second embodiment). The display unit 22 is a display and displays information to be shown to the assistant. The communication unit 23 is a LAN interface.

  The operation reception unit 31 is, for example, a keyboard or a touch panel, and receives customer operations. The customer inputs a message via the operation reception unit 31. The display unit 32 is a display and displays information to be shown to the customer. The communication unit 33 is a LAN interface.

  The operation reception unit 41 is, for example, a keyboard or a touch panel, and receives an operation of a manager of a merchandise sales company. The administrator inputs request information about a product desired to be introduced to the customer via the operation reception unit 31. The display unit 42 is a display and displays information to be shown to the administrator. The communication unit 43 is a LAN interface.

[Operation sequence]
