[0014] <Details of the embodiment> Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0015] <Summary of the Invention> A sales support server according to one embodiment of the present invention comprises a video acquisition unit that acquires data obtained by the camera unit of the user terminal, a guide provision unit that inputs the acquired data and provides the user terminal with guide information necessary for generating an AI to perform a monetary evaluation for each item to be sold, and a detailed information acquisition unit that acquires detailed information of the items to be sold according to the guide information. As a result, the user can simply take a picture of the items to be sold and receive guidance from the generating AI on the information necessary for evaluating those items, enabling them to proceed with the sales procedure easily and accurately.

[0016] <Example Hardware Configuration> Figure 1 is a block diagram showing an example of the hardware configuration of the sales support server 100 in this embodiment. The sales support server 100 includes a CPU (Central Processing Unit) 101, memory 102, auxiliary storage device 103, and a communication interface 104. These components are interconnected by a bus 105. The CPU 101 is a processor that performs overall control and various calculations of the sales support server 100. The memory 102 temporarily stores programs and data executed by the CPU 101. The auxiliary storage device 103 is storage for permanently storing programs and data. The communication interface 104 is an interface for communicating with external devices via a network.

[0017] <Network Configuration Example> Figure 2 shows an example of the network configuration of the sales support system 1 of this embodiment. The sales support system 1 includes a sales support server 100, a user terminal 200, and a business terminal 300. The sales support server 100 is connected to the user terminal 200 and the business terminal 300 so as to be able to communicate via a network 10 such as the Internet.

[0018] The user terminal 200 takes photos of the items to be sold and exchanges data with the sales support server 100. The user terminal 200 can be, for example, a smartphone, tablet, or PC.

[0019] The business terminal 300 retrieves information on the items to be sold from the sales support server 100 and displays the desired purchase price. Users of the business terminal 300 include buyers and used goods dealers.

[0020] <Video Acquisition Section> The video acquisition unit 111 acquires data continuously captured and transmitted from the user terminal 200 and passes it to the guide provision unit 112. The user terminal 200 is, for example, a smartphone or tablet. When the user turns on the camera function and photographs items in the room, that data is transmitted from the user terminal 200 to the sales support server 100 and acquired by the video acquisition unit 111.

[0021] <Guide Provider Department> The guide provision unit 112 analyzes data obtained from the user, identifies the product to be sold, and then has a function to guide the user so that they can interactively take pictures of the product to obtain product information necessary for the monetary evaluation of that product.

[0022] Specifically, the guide provision unit 112, for each of the products photographed in succession, causes the generating AI to generate initial guide information based on the product category and attribute information identified by the generating AI, and transmits it to the user terminal 200 as voice. The initial guide information is a guide for photographing information necessary for basic evaluation and assessment, such as the overall appearance of the product, each part, accessories, model number, and condition, and instructs the user on how to photograph using voice, text, images, etc. Alternatively, the initial guide information may be registered in a predetermined database in association with the product category and attribute information, and then read by the generating AI and transmitted as voice.

[0023] Below are examples of initial guide information for each product category. The guide information is illustrative and does not actually refer to specific tables or anything like that. Instead, the generating AI determines the necessary information and generates it, including how to present it. Bags and wallets "Please take a picture of the entire product from the front." "Please take a picture of the inside of the product." "Please take a close-up photo of the brand logo or tag." "Please take a close-up photo of the metal part." • Clothing and shoes "Please take photos of the entire product from the front and back." "Please take close-up photos of the tags and care labels." "Please take close-up photos of parts such as buttons and zippers." "Please take a picture of the soles of your shoes." · Home appliances "Please take photos of the entire product from the front, side, and back." "Please take a close-up photo of the label that contains the model number and serial number." "Please take a picture of the accessories (remote control, cables, etc.)." "Please film the process of checking the operation."

[0024] The user takes a photograph of the product to be sold (initial photography) according to the initial guide information received on the user terminal 200. The guide provision unit 112 analyzes the initial photography data sent by the user and determines whether sufficient information necessary for evaluation has been obtained.

[0025] If the guide provision unit 112 determines that necessary information is missing, it identifies the missing information and generates additional guide information to obtain it. The additional guide information provides detailed instructions on shooting methods and targets that were not covered in the initial guide and is provided to the user terminal 200 via voice.

[0026] Examples of additional guide information are shown below. "There appears to be a scratch on the left side of the product. Please take a close-up photo of the scratched area." "Please also photograph the inside of the pockets." "Please take a close-up photo of the instruction manual for the included accessories." "Please film the product in working order for a longer duration."

[0027] The user takes additional photos of the items to be sold (additional photography) according to the additional guide information. The guide provision unit 112 analyzes the data from the additional photography and determines again whether all the information necessary for evaluation has been collected. This interactive guidance and photography process is repeated until all the necessary information is collected.

[0028] As described above, the guide provision unit 112 can efficiently and reliably acquire information necessary for evaluating and assessing the products to be sold through interactive communication with the user, using initial guide information and additional guide information. This makes it possible to collect sufficient data for making an appropriate financial evaluation while minimizing the effort required from the user.

[0029] <Product details information> The detailed information acquisition unit 113 has the function of extracting detailed information necessary for the monetary evaluation of the product to be sold from the data acquired through interactive interaction with the user by the guide provision unit 112.

[0030] Specifically, the detailed information acquisition unit 113 receives data taken by the user according to the initial guide and additional guides as input, and automatically extracts detailed information such as each part of the product, accessories, and condition using image analysis technology and machine learning algorithms.

[0031] The following is an example of the information extracted by the detailed information acquisition unit 113. • Basic product information Product name or model number Brand name Category Information Size, color, material • Product condition information Presence and extent of scratches and stains Condition of use and degree of deterioration over time Presence and condition of accessories Operation verification results • Information regarding the scarcity and demand for products Whether it is a limited edition model or a rare item Current market popularity and circulation

[0032] The detailed information acquisition unit 113 utilizes a generation AI to automatically extract detailed product information from data photographed by the user with high accuracy.

[0033] The extracted detailed information provides important clues for evaluating the monetary value of the product. For example, the better the condition of the product and the rarer it is, the higher its value tends to be. The detailed information acquisition unit 113 quantifies this information and passes it to the evaluation algorithm to achieve an appropriate monetary valuation of the product.

[0034] <Generation AI> To realize the sequence of operations in this invention, the Generating AI 114 employs a multimodal learning model that combines advanced AI technologies such as natural language processing, image recognition, and machine learning. The Generating AI 114 organically links the functional components of product identification, guide information generation, detailed information extraction, evaluation algorithm, and training data management. In product identification, image recognition technology is used to identify products from data. In guide information generation, shooting guides are automatically generated using natural language generation technology based on the identified product information. In detailed information extraction, detailed product information is extracted from data shot according to the guide using the multimodal learning model. In the evaluation algorithm, an appropriate monetary evaluation is performed using machine learning and expert systems based on the detailed information. In training data management, the training data used in each module is managed and continuously updated to improve the model's performance. By combining these advanced AI technologies, efficient and highly accurate product evaluation is achieved.

[0035] <Registration Department> The registration unit 115 associates the detailed information of the items to be sold obtained by the detailed information acquisition unit 113 with information about the items to be sold themselves and registers it in the database 116 as sales product information. Sales product information includes information necessary for appraisal and purchase decisions, such as product name, model number, manufacturer name, condition (presence or absence of scratches or stains, signs of use, etc.), presence or absence of accessories, size, color, material, and specifications.

[0036] Database 116 is built on the auxiliary storage device 103 of the sales support server 100 and stores the sales product information registered by the registration unit 115.

[0037] <Department for Providing Information on Products for Sale> The sales product information provision unit 117 provides sales product information registered in the database 116 to multiple business terminals 300 via the network 10. The business terminals 300 are terminals used by buyers, used goods dealers, and the like.

[0038] Specifically, the Sales Product Information Provision Unit 117 periodically or in real time pushes newly registered sales product information to the business terminal 300. Alternatively, it searches for and provides sales product information that matches the specified criteria in response to a request from the business terminal 300. The user of the business terminal 300 refers to the provided sales product information to determine whether to purchase the product and to set a purchase price.

[0039] Thus, the registration unit 115 and the sales item information provision unit 117 are responsible for providing detailed information about the items to be sold, collected from users, to businesses that purchase or sell them. This facilitates matching users with businesses and supports users' selling activities.

[0040] The Amount Reception Unit 118 receives the desired purchase price for items for sale from multiple business terminals 300 that have received product information for sale from the Product Information Provision Unit 117. Specifically, the users of the business terminals 300 refer to the provided product information for sale, enter the desired purchase price for the items that can be purchased, and send it from the business terminal 300 to the sales support server 100. The Amount Reception Unit 118 receives the desired purchase prices sent from the business terminals 300 and records them in the database 116.

[0041] At this time, the payment receiving unit 118 manages the desired purchase price for each business terminal 300. In other words, if different desired purchase prices are offered by multiple business terminals 300 for the same item to be sold, the unit maintains the correspondence between each business terminal 300 and the desired purchase price.

[0042] The amount provision unit 119 provides the requested purchase price received by the amount reception unit 118 to the user terminal 200 via the network 10. Specifically, in response to a request from the user terminal 200, the amount provision unit 119 sends to the user terminal 200 a list of the requested purchase prices that have been received at that time.

[0043] The user terminal 200 displays a list of offers from multiple businesses, along with detailed information about the items to be sold. The user can compare the offered prices and decide on a buyer and selling price.

[0044] Thus, the price receiving unit 118 and the price providing unit 119 are responsible for collecting desired purchase prices from multiple businesses and presenting them to the user. This allows the user to understand the market value of the items they are selling and to sell them at a higher price. At the same time, it also allows businesses to efficiently search for items to purchase and acquire them at appropriate prices.

[0045] The highest price offering unit 120 presents the user terminal 200 with the highest price among the multiple purchase offer amounts received by the price receiving unit 118. Specifically, the highest price offering unit 120 extracts the highest price from the purchase offer amounts managed by the price receiving unit 118 and notifies the user terminal 200 of that price and the corresponding business information.

[0046] On the user terminal 200's display screen, detailed information about the items to be sold is highlighted, along with the highest desired purchase price and the name of the company offering it. The user can use this information to decide where to sell their items.

[0047] Meanwhile, the settlement unit 121 settles the sale of the items at the highest desired purchase price offered by the highest price offering unit 120. Specifically, if the user agrees to sell at the highest desired purchase price, the settlement unit 121 transfers ownership of the items to the buyer at that price and pays the sale price to the user. Payment processing can be performed within this system.

[0048] The settlement unit 121 executes fund transfers between users and businesses using various payment methods, such as credit card payments, bank transfers, and electronic money payments. Upon completion of the payment, it also updates the information on sold items and manages sold items.

[0049] Thus, the highest price offering unit 120 and the settlement unit 121 are responsible for presenting the user with the highest price among multiple desired purchase prices and realizing the sale at that price. As a result, users can sell their items under the most favorable conditions without having to engage in complicated price negotiations.

[0050] If the guide provision unit 112 determines that there is insufficient information necessary to perform a monetary evaluation, it generates guide information that instructs the user terminal 200 on how to take pictures and what to photograph in order to acquire that information. In this embodiment, the guide provision unit 112 converts the guide information into audio data and transmits it to the user terminal 200, thereby providing the user with an audio guide.

[0051] Specifically, the guide provision unit 112 inputs guide information in text format into the speech synthesis engine 123 and generates audio data. The speech synthesis engine 123 is software for converting text into natural-sounding speech and operates on the sales support server 100. The speech synthesis engine 123 can generate high-quality speech by employing, for example, the latest speech synthesis technology using AI-based machine learning.

[0052] The voice data generated by the speech synthesis engine 123 is transmitted to the user terminal 200 via the network 10. The user terminal 200 plays back the received voice data and provides the user with a voice guide.

[0053] Examples of audio guidance include "Please take a photo so that the product tag is visible," "Please also take a photo of the bottom of the product," and "Please take a close-up photo of the product." Users can take photos of the items they are selling while listening to these audio guides.

[0054] By using voice guidance, users do not need to check shooting methods while looking at the screen; they can take appropriate photos simply by following the voice instructions. This improves user convenience and allows for more efficient collection of necessary information.

[0055] <Processing flow of the sales support server> As shown in Figure 4, the processing flow of the sales support server according to this embodiment will be explained below. First, when the user takes a picture of the item to be sold with a smartphone or the like, the video acquisition unit receives the captured data (step S401). The generation AI identifies the items that can be sold in the video (step S402) and checks whether there is any missing information necessary for evaluation (step S403). If there is missing information ("Yes" in step S403), the guide provision unit provides voice guidance to the user to take additional pictures, and the user takes additional pictures (step S404). If there is no missing information, the process proceeds to the next step. The detailed information acquisition unit acquires detailed information about the items (step S405). Once all items have been photographed according to the guide information (steps S401 to S405), the registration unit registers the sold item information in the database (step S406). Next, the sold item information provision unit provides the sold item information to the business operator (step S407). The price acceptance unit accepts the desired purchase price from the business operator (step S408). The price provision unit presents the desired purchase price to the user. The highest bidder unit presents the user with a purchase price (step S409). The user decides whether to accept the sale, and if accepted, the settlement unit executes the sale settlement, completing the sale process on the platform. If not accepted, the sale is unsuccessful. In this flow, the sales support server of the present invention receives a sale request from a user, automates a series of processes from product evaluation using generation AI, presentation of purchase price offers from multiple businesses, to sale settlement.

[0056] <Processing flow of the guide provision department> As shown in Figure 5, the guide provision unit of the present invention performs the following processes. First, when a user photographs the product to be sold with a smartphone or the like and the data is received (step S501), the guide provision unit analyzes the photographed data and identifies the product to be sold (step S502). Based on the identified product category and attribute information, initial guide information is generated (step S503) and provided to the user terminal. When the user photographs the product according to the initial guide information (initial photography) (step S504) and obtains detailed product information, the guide provision unit analyzes the initial photographed data and determines whether the information necessary for evaluation is sufficient (step S505). If there is a deficiency ("Yes" in step S505), the guide provision unit identifies the missing information and generates additional guide information to obtain that information (step S506). The additional guide information is provided to the user terminal by voice. The user photographs the product again according to the additional guide information (additional photography) (step S507). If there is no deficiency ("No" in step S505), the process is transferred to the detailed information acquisition unit and the product is registered (step S508). In this process, the guide provision department efficiently and reliably acquires the information necessary for evaluating and assessing the products to be sold through interactive communication with users.

[0057] <Example of a screen in the user terminal of the present invention> Referring to Figures 6 to 9, an example of the screen of a user terminal 200 in one embodiment of the present invention will be described.

[0058] When the user activates the camera function of the user terminal 200, guide information transmitted from the guide provision unit 112 is displayed on the screen, as shown in Figure 6. The guide information is provided as text such as "Take a picture with the product facing forward," as well as voice instructions such as "Please also include the tag" and "Please also include the bottom," and combinations thereof. The user then takes sequential, continuous photographs of the products to be sold, following this guide information.

[0059] When a user photographs multiple items, the photographed items are displayed as thumbnail images at the top of the screen, as shown in Figure 7. This allows the user to visually understand the list and quantity of items they intend to sell.

[0060] Once the product photography is complete, a product registration confirmation screen is displayed, as shown in Figure 8. This screen displays the photographed product image along with information such as the product name and brand name extracted by the detailed information acquisition unit 113. For example, as shown in the figure, the detailed product information extracted by the detailed information acquisition unit 113 is displayed in the center of the screen, recognizing the item name, category, subcategory, brand name, and condition (e.g., "damaged or stained"). This information is automatically extracted from the photographed product image.

[0061] A "List Item" button is displayed at the bottom of the screen. Users can review the displayed product information, and if there are no problems, tap this button to proceed with the process of selling (listing) the item.

[0062] The above is a detailed explanation of the product registration confirmation screen of the user terminal 200 shown in Figure 3. On this screen, detailed information of the products photographed by the user is automatically extracted and displayed, and the user can make a decision to sell (list) each item after confirming it. In this way, in the embodiment of the present invention, by presenting the automatic extraction of product information and the confirmation screen sequentially for each product, the burden on the user in the selling procedure is greatly reduced.

[0063] When a user chooses to sell (list) an item, the registration unit 115 registers the item for sale in the database 116. The item for sale information provision unit 117 provides this information to multiple business terminals 300, and the price acceptance unit 118 accepts the desired purchase price from each business terminal 300.

[0064] The highest offer unit 120 presents the user terminal 200 with the highest offer among the accepted buyback offers. As shown in Figure 8, the highest buyback offer is displayed on the screen of the user terminal 200. Based on this information, the user decides whether to accept the sale. If the sale is accepted, the settlement unit 121 executes the buy and sell settlement at the offered price, and the sale of the goods is completed.

[0065] As described above, the example screen of the user terminal 200 in this embodiment is designed to allow the user to intuitively understand the entire process from taking a series of photos of the product to being presented with the purchase price and making a decision to sell.

[0066] The embodiments described above are merely illustrative to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof. [Explanation of Symbols]
