Description

[Technical Field]

[0001] The present invention relates to an information providing system that provides information such as signage used in stores and the like. [Background technology]

[0002] Conventionally, information provision systems such as signage systems that install display devices in facilities such as stations or stores to transmit information such as advertisements or news have been known. Methods for using signage systems to increase users' purchasing motivation have also been proposed. For example, Patent Document 1 proposes detecting a mobile terminal within a predetermined distance from a signage device, and outputting special benefit information associated with the signage if the mobile terminal has stayed within the range for a set period of time or longer. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-53502 Summary of the Invention [Problem to be solved by the invention]

[0004] In a typical signage device, the content to be displayed and the display time are determined by the content distributor. Therefore, if the displayed signage does not attract the user's interest, the user will pass by without looking at the signage. Therefore, even if special information is provided as in Patent Document 1, the requirement for the length of stay will not be met, and the desire to purchase will not be enhanced.

[0005] The present invention has been made to solve the above-mentioned problems, and has as its object to provide an information providing system that can increase users' purchasing motivation. [Means for solving the problem]

[0006] The information provision system of the present invention comprises a signage device that displays normal content including product images and text information related to the products, and a terminal device that transmits user identification information.When the signage device receives the identification information from the terminal device, it switches the normal content to custom content tailored to the user.The custom content includes the same text information as the normal content, and the product image has been changed based on user preference information obtained based on the identification information. [Effects of the Invention]

[0007] According to the information providing system of the present invention, custom content including product images that have been changed based on the user's preference information is displayed, thereby increasing the user's desire to purchase. [Brief explanation of the drawings]

[0009] An information provision system according to an embodiment of the present invention will be described below with reference to the drawings. A signage system will be described below as an example of an information provision system. In each drawing, identical or corresponding parts are designated by the same reference numerals, and their description will be omitted or simplified as appropriate. Furthermore, the shape, size, and arrangement of the configurations shown in each drawing may be modified as appropriate within the scope of the present invention.

[0010] Embodiment 1 FIG. 1 is a schematic configuration diagram of a signage system 100 according to a first embodiment. The signage system 100 of this embodiment provides signage in an apparel store that sells clothing. As shown in FIG. 1, the signage system 100 comprises a signage device 1, a terminal device 2, and a management server 3. Although FIG. 1 shows an example in which one signage device 1 is provided, the number of signage devices 1 may be two or more.

[0011] The signage device 1 is installed on a wall or shelf in an apparel store and displays content related to clothing products. The terminal device 2 is a terminal device such as a tablet or smartphone carried by a customer who visits the store to shop. In this embodiment, the terminal device 2 is a tablet that is installed in a shopping cart and used as a POS terminal for registering and paying for products. The signage device 1 and the terminal device 2 can communicate wirelessly via wireless LAN, infrared rays, Bluetooth (registered trademark), or the like.

[0012] Management server 3 has a POS server function that manages product information about products sold in the store and user information about users who use the store, and a content server function that manages content displayed on signage system 100. Signage device 1, terminal device 2, and management server 3 can communicate with each other via wired or wireless communication via network 200 such as the Internet.

[0013] First, a store in which the signage system 100 of the present embodiment is installed will be described. As shown in FIG. 1 , the store in which the signage system 100 of the present embodiment is installed is divided into shelves 5 on which sample products 50 are displayed and shelves 6 on which packaged products 60 are displayed. The sample products 50 are products that customers can check the feel and texture of and try on. One sample product for each product type and size is displayed on the shelf 5 unpackaged and hung on a hanger. The packaged products 60 are products that customers purchase and are packaged in a package 61 and displayed on the shelf 6. The display method of the sample products 50 and packaged products 60 is not limited to the example shown in FIG. 1 . For example, the sample products 50 may be hung on a single hanger placed independently of the shelf 5.

[0014] Fig. 2 shows an example of a sample product 50 according to the first embodiment. As shown in Fig. 2, a tag 51 is attached to the sample product 50. In addition to product information such as the product name, price, and size that is typically found on a tag, the tag 51 also contains identification information 52 for linking the tag 51 to a packaged product 60. Furthermore, to prevent users from accidentally purchasing the sample product 50, the tag 51 does not contain a barcode that is used for payment for the product.

[0015] FIG. 3 shows an example of a packaged product 60 according to the first embodiment. As shown in FIG. 3, the packaged product 60 is folded and packed in a package 61. At least a portion of the package 61 is transparent or translucent. In addition to the packaged product 60, a specification sheet 62 is packed inside the package 61. The specification sheet 62 is a substitute for the tag of the packaged product 60, and in addition to product information such as the product name, price, and size that is printed on a typical tag, it also contains identification information 63 for linking the packaged product 60 to the sample product 50. The identification information 63 is, for example, a shelf number, and a user tries on the sample product 50, and when purchasing the sample product 50, the user purchases the packaged product 60 having the same identification information 63 as the identification information 52 on the tag 51.

[0016] As described above, separating the sample items 50, which are used for trying on or checking the feel of the product, from the packaged items 60 that are actually purchased, offers a variety of advantages, including the following. First, after trying on the sample items 50, customers can always purchase new packaged items 60. This reduces the effort required of store clerks to prepare new items. Furthermore, in stores that sell both food and clothing, customers may be reluctant to put unpackaged clothing in the same cart as food, but using packaged items 60 can alleviate this reluctance.

[0017] Furthermore, while in the past, when a store clerk stocked products, it was necessary to unpack the simple packaging of the delivered products, hang them on hangers, and arrange them on the shelves, in this embodiment, the packaged products 60 can be arranged on the shelves in the state in which they were delivered. This significantly reduces the labor required for stocking, and also reduces costs because hangers for display are no longer necessary. Furthermore, because purchased products are packed in packages 61, there is less damage when they are returned. Furthermore, because it is possible to display products in a compressed state, the number of products that can be displayed on the shelves increases compared to the past, and the amount of inventory can be seen at a glance.

[0018] Next, a description will be given of signage system 100 according to the present embodiment. Fig. 4 is a control block diagram of signage system 100 according to the first embodiment. As shown in Fig. 4, signage device 1 includes control device 11, storage device 12, communication device 13, display device 14, and operation device 15.

The control device 11 controls the display of content on the display device 14 according to the display information of the content stored in the storage device 12 and information received from the management server 3. The control device 11 also transmits information input via the communication device 13 and the operation device 15 to the management server 3.

[0020] The storage device 12 is composed of a volatile memory such as RAM, a non-volatile memory such as ROM, HDD, or flash memory, or both, and stores the content downloaded from the management server 3 in association with the display information of the content. The storage device 12 also stores various programs executed by the control device 11 and various data required for executing the programs.

[0021] The communication device 13 communicates with the management server 3 via the network 200, and downloads content and content display information from the management server 3. The communication device 13 also receives information transmitted from the terminal device 2 and transfers it to the management server 3.

[0022] The display device 14 is, for example, a liquid crystal display, and displays content under the control of the control device 11. The operation device 15 is a touch panel formed integrally with the display device 14, and receives input from the user.

[0023] The content displayed on the signage device 1 of this embodiment includes normal content that is displayed according to a preset schedule, and custom content that is displayed when a user carrying a terminal device 2 is near the signage device 1. These contents are created in advance as moving images or still images, provided to the signage device 1 from the management server 3, and stored in the storage device 12.

[0024] The regular content is, for example, an advertisement for a new product or information about seasonal recommended products, and is displayed repeatedly at set intervals. The custom content is regular content customized based on user identification information transmitted from a terminal device 2 near the signage device 1. The content display information includes a display schedule for the regular content, layout information for each content, etc. The display information is provided by the management server 3 in association with each content.

[0025] The terminal device 2 comprises a control device 21, a storage device 22, a communication device 23, a display device 24, an operation device 25, and a reading device 26. The control device 21 is configured by a processor such as a CPU that executes a program stored in the storage device 22, a dedicated processing circuit such as an ASIC or FPGA, or both. The control device 21 registers the product read by the reading device 26 as a product to be purchased, settles the bill, and performs a settlement process for the settled product. In the terminal device 2 of this embodiment, prepaid cards, Payment can be made by credit card, electronic money, or barcode. The storage device 22 is composed of a volatile memory such as RAM, a non-volatile memory such as ROM, HDD, or flash memory, or both, and stores various programs executed by the control device 21 and various data required for executing the programs.

[0026] The communication device 23 is a network interface that transmits and receives data via wireless communication with the signage device 1 and the management server 3. When a user logs in to the terminal device 2, the communication device 23 transmits the information entered at the time of login to the management server 3 as the user's identification information. The communication device 23 also transmits the user's identification information as a beacon at regular time intervals. When a product is registered in the terminal device 2, the communication device 23 transmits information about the registered product to the management server 3 as registration information, and when the user makes a payment, the communication device 23 transmits information about the payment to the management server 3 as payment information.

[0027] The display device 24 is, for example, a liquid crystal display, and displays information about the products to be registered, information about the settlement and payment of the products, and notifications from the management server 3. The operation device 25 is, for example, a touch panel formed integrally with the display device 24. The operation device 25 is operated by the user to log in when starting use, manually register products without barcodes, give payment instructions, select a payment method, and input information for payment (such as a PIN number).

[0028] The reading device 26 is a device that irradiates a laser scanning line onto a product to read a barcode attached to the product. Product information read by the reading device 26 is sent to the control device 21. The reading device 26 may also include a card reader that reads information from a prepaid card or credit card, a scanner that reads information from electronic money or a barcode, or a camera.

[0029] The management server 3 includes a control device 31, a storage device 32, and a communication device 33. The control device 31 is configured with a processor such as a CPU that executes programs stored in the storage device 12, a dedicated processing circuit such as an ASIC or FPGA, or both. The management server 3 manages the content displayed on the signage device 1, user information about users, and product information about products in the store. Specifically, the control device 31 stores the registration information registered on the terminal device 2, performs payment and settlement, and extracts user preference information and inventory information.

[0030] The storage device 32 has a user information database 321, a product information database 322, and a content information database 323. In Fig. 4, "database" is abbreviated as "DB."

[0031] The user information database 321 stores user information including the identification information, name, address, and preference information of the user who uses the terminal device 2. The preference information is information indicating preferences regarding clothing, and includes information such as preferred color (light or dark), preferred length, preferred silhouette, and priority items (functionality, price, etc.). The preference information may also include information such as the user's age, gender, height, and build. This information is entered by the user when registering as a member, and is stored in the user information database 321.

[0032] The product information database 322 stores product information about products in the store, registration information received from the terminal device 2, and inventory information indicating whether or not each product in the store is in stock or the number of products in stock. The registration information includes information such as the product category, product code, product name, product quantity, and price. The content information database 323 stores regular content and custom content to be displayed on the signage device 1, and content display information.

[0033] The communication device 33 communicates with the signage device 1 via the network 200, and provides content and content display information to the signage device 1. In addition, the communication device 33 transmits preference information and inventory information to the signage device 1 in response to a request from the signage device 1. Furthermore, the communication device 33 communicates with the terminal device 2 via the network 200, and transmits information related to payment for registered products of the terminal device 2.

[0034] 5 is a diagram showing a flow of content display in signage system 100 according to embodiment 1. First, signage device 1 downloads the content and display information of the content from management server 3 (S1). The downloaded content and display information are stored in storage device 12 of signage device 1. Then, signage device 1 displays the regular content on display device 14 according to the display schedule of the display information (S2).

[0035] FIG. 6 is an example of normal content 140 displayed on signage device 1 according to embodiment 1. As shown in FIG. 6, normal content 140 includes normal product image 141 and text information 142 that displays product information in text. Normal image 141 includes an image of the clothing product and a model wearing the clothing. The product information includes the product brand name, product name, product description, and price. The product description includes information such as the product's key features, material, size options, and color options. Note that the product information may include information other than the above.

[0036] Returning to Fig. 5, when the user of terminal device 2 starts shopping, the user's identification information is input to terminal device 2 (S3). Here, the user's membership number may be input as the identification information using operation device 25, or the identification information may be input by reading a membership card or prepaid card with reader 26. Then, the identification information is transmitted from terminal device 2 at predetermined time intervals (S4).

[0037] When the terminal device 2 approaches the signage device 1, the signage device 1 receives the identification information transmitted from the terminal device 2 (S5). As an example, when the terminal device 2 transmits the identification information using Bluetooth (registered trademark), the signage device 1 receives the identification information when the distance between the terminal device 2 and the signage device 1 is within 10 m.

[0038] The signage device 1 transfers the identification information received from the terminal device 2 to the management server 3 (S6). If multiple terminal devices 2 are located near the signage device 1, the management server 3 transfers the identification information of the terminal device 2 that is closest (has the strongest radio wave intensity) to the management server 3. Upon receiving the identification information from the signage device 1, the management server 3 extracts the user preference information corresponding to the identification information from the user information database 321 (S7), and transmits the extracted preference information to the signage device 1 (S8).

[0039] Based on the preference information received from management server 3, signage device 1 selects custom content stored in storage device 12 (S9), and switches the normal content displayed on display device 14 to the custom content (S10).

[0040] FIG. 7 illustrates an example of customized content 140A displayed on signage device 1 according to the first embodiment. As illustrated in FIG. 7, customized content 140A includes customized image 141A of a product and text information 142 of product information. The text information 142 is the same as that of the normal content. Customized image 141A is obtained by modifying normal image 141 of normal content 140 based on preference information. For example, if the preference information indicates that the user prefers dark colors, as illustrated in FIG. 7, the color of the clothes in customized image 141A is modified to a darker color than the color of the clothes in normal image 141 from among the available colors. Furthermore, the age, gender, height, and physique of the model in customized image 141A are modified according to the age, gender, height, and physique of the user, which are included in the preference information. In this way, by customizing only the product image and displaying the same product and product information as in normal content 140, custom content 140A can attract users' attention to the products that the store wants to sell.

[0041] If the preference information includes the user's preferred length, silhouette, and important details, the product displayed in customized content 140A may be changed from the product displayed in normal content 140. In this case, not only custom image 141A in customized content 140A but also text information 142 of the product information are changed to that of the customized product. Here, for example, information related to length and silhouette is linked to the product code, and the product with the product code corresponding to the preference information is selected and displayed as customized content 140A.

[0042] 5, it is determined whether operation device 15 of signage device 1 has been operated (S11). Here, it is determined whether operation device 15 of signage device 1, which is configured as a touch panel, has been touched by a user. If operation device 15 has not been operated (S11: NO), the display of custom content 140A continues.

[0043] On the other hand, if the operating device 15 is operated (S11: YES), the signage device 1 transmits to the management server 3 a stock confirmation request for the product currently displayed on the display device 14 (S12). Upon receiving the stock confirmation request from the signage device 1, the management server 3 extracts stock information for the product from the product information database 322 (S13) and transmits it to the signage device 1 (S14).

[0044] The signage device 1 changes the custom content based on the inventory information received from the management server 3 (S15). Fig. 8 shows an example of the changed custom content 140B displayed on the signage device 1 according to the first embodiment. Fig. 8(a) shows an example of the display when the product is in stock, and Fig. 8(b) shows an example of the display when the product is out of stock. The custom content 140B includes product location information 143 according to the inventory.

[0045] 8(a), when a product is in stock, the shelf number on which the product is displayed is displayed as product location information 143. The shelf number is identification information 63 written on the specification sheet 62 of the packaged product 60.

[0046] On the other hand, as shown in Figure 8(b), if the product is out of stock, a two-dimensional code for directing the user to an EC site is displayed as product location information 143. In this way, by displaying product location information 143 according to the stock in custom content 140B, it is possible to provide customers who show interest in the signage with information for purchasing the product. This increases the user's purchasing opportunities.

[0047] As described above, the signage system 100 of this embodiment can switch the displayed content based on the preference information of a user near the signage device 1. This allows the user to imagine what the product will look like when actually used (worn), which can increase the user's motivation to purchase. It also reduces the effort required for store clerks to switch content depending on the user.

[0048] 5 is not essential and can be omitted. In this case, operation device 15 of signage device 1 does not have to be a touch panel integrated with display device 14. Alternatively, signage device 1 may not be provided with operation device 15.

[0049] Embodiment 2 A second embodiment will now be described. Fig. 9 is a control block diagram of a signage system 100A according to the second embodiment. As shown in Fig. 9, the signage system 100A of the present embodiment differs from the first embodiment in that it includes an information acquisition device 4 in addition to a signage device 1, a terminal device 2, and a management server 3. The information acquisition device 4 may be configured separately from the signage device 1, or may be configured as a part of the signage device 1.

[0050] The information acquisition device 4 is attached to the display device 14 of the signage device 1 and acquires information about people standing in front of the display device 14. The information acquisition device 4 is, for example, a camera that captures images of people, or a LiDAR (Light Detection And Ranging) that acquires data such as people's movements and approximate body size, or a combination of these. The information acquisition device 4 is connected to the signage device 1 via wired or wireless communication, and the image information acquired by the information acquisition device 4 is output to the control device 11 of the signage device 1.

[0051] FIG. 10 is a diagram showing a flow of content display in signage system 100A according to embodiment 2. The content shown in FIG. 10 is displayed in parallel with the content display shown in FIG. 5. As shown in FIG. 10, first, as in embodiment 1, signage device 1 downloads the content and display information of the content from management server 3 (S1). The downloaded content and display information are stored in storage device 12 of signage device 1. Then, signage device 1 displays the regular content on display device 14 according to the display schedule of the display information (S2).

[0052] Then, the information acquisition device 4 acquires image information of the person in front of the signage device 1 (S20). The image information acquired by the information acquisition device 4 is transmitted to the signage device 1 (S21). The signage device 1 analyzes the image information received from the information acquisition device 4 (S22). Here, the signage device 1 analyzes the image information using known image recognition technology, and detects the color or shape of the person's clothing in the image, or the person's age, gender, physique, etc.

[0053] Then, based on the analysis results of the image information, signage device 1 selects custom content stored in storage device 12 (S23), and switches the normal content displayed on display device 14 to the custom content (S24). That is, in this embodiment, image information of a person acquired by information acquisition device 4 is analyzed, and the analysis results are used as user preference information. For example, if the analysis results of the image information indicate that the user is wearing dark-colored clothing, the color of the clothing in custom image 141A is changed to a darker color than the color of the clothing in normal image 141, as shown in FIG. 7. Furthermore, the age, gender, height, and physique of the model in custom image 141A are changed according to the age, gender, height, and physique of the person in the analysis results of the image information. Thereafter, the same processes as those in S11 to S15 of the first embodiment shown in FIG. 5 are performed.

[0054] As described above, the signage system 100A of this embodiment can acquire preference information from an image of a user near the signage device 1 and switch the displayed content. This allows even users whose preference information is not stored in the management server 3 to be provided with an image of the user actually using (wearing) the product, thereby increasing the user's motivation to purchase. It also reduces the effort required for store clerks to switch content depending on the user.

[0055] In the signage system 100A of the present embodiment, the terminal device 2 may be omitted, and only content may be displayed based on information acquired by the information acquisition device 4. In the above embodiment, the information acquisition device 4 acquires image information of people in front of the signage device 1A, but the information acquired by the information acquisition device 4 is not limited to this. For example, the information acquisition device 4 may be attached to a wall of a store or the like and detect people flow information indicating the movement of people within the store. In this case, the signage device 1 analyzes the people flow information received from the information acquisition device 4 and switches the content to be displayed on the display device 14.

[0056] For example, based on the people flow information, the signage device 1 measures the distance between a person and a product, determines whether a person has touched a product, or measures the time a person has spent near a product. Then, based on the analysis results of the people flow information, the signage device 1 selects custom content stored in the storage device 12 and switches the normal content displayed on the display device 14 to the custom content. In this case, the custom content is content related to a product based on the analysis results. For example, content related to a product that is close to a person, content related to a product that has been touched by a person, or content related to a product where a person has spent a longer time than a reference time is displayed as custom content.

[0057] The above is a description of the embodiments, but the above embodiments can be modified and combined. For example, in the above embodiments, signage systems 100 and 100A have been described as examples of information provision systems, but the present invention is not limited to this and can be applied to systems that display information other than signage. Furthermore, the signage device 1 is not limited to the above embodiments and may be a device that displays information other than signage. Furthermore, the signage device 1 may be configured integrally with the terminal device 2. In this case, the terminal device 2 has the functions of the signage device 1, and the normal content and custom content of the above embodiments are displayed on the terminal device 2.

[0058] In the above embodiment, product location information 143 is displayed when a user performs an operation while custom content 140A is displayed, but this is not limiting. For example, product location information 143 may be displayed when a preset time has elapsed since custom content 140A was displayed.

[0059] Furthermore, in the above embodiment, custom image 141A displayed in custom content 140A is an image of a model wearing the product, but an image of a user trying on the product may also be displayed as custom image 141A. In this case, the try-on image may be created by a generation AI based on the user's facial image or physique acquired by information acquisition device 4.

[0060] Furthermore, preference information of not only the user himself / herself but also that of his / her family members may be registered as preference information, and in addition to custom content 140A based on the preference information of the user himself / herself, custom content 140A customized based on the preference information of the family members may be displayed.

[0061] Furthermore, the signage device 1 may transmit the user's identification information and the analysis results of the information about the user acquired by the information acquisition device 4 to the management server 3. The management server 3 stores the analysis results received from the signage device 1 as user preference information in the user information database 321. The preference information stored in the user information database 321 may be used to customize the content displayed on the signage device 1 as described in the above embodiment, and may also be used to display recommendations when the user is shopping on an e-commerce site.
