When it is determined that there is no specific commodity name in the commodity names, the Web server transmits data of the standard explanation form to the portable information terminal 21.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a product selection method and a product selection system for providing food and drink. [Background technology]

[0002] There is a certain number of customers with food allergies, and the number is increasing. Conventionally, an automatic ticket vending machine equipped with an allergy selection button for identifying allergic foods has been proposed (Patent Document 1: JP 2011-198026 A). Another proposed information provision system selects dishes suitable for a customer by pre-registering customer information on a server at a designated store (Patent Document 2: JP 2019-023829 A). Another proposed menu display method at a hotel or inn uses a computer to compare allergen information for dishes on a menu with customer information and output personalized menu information (Patent Document 3: JP 2019-046232 A).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-198026 [Patent Document 2] Japanese Patent Application Publication No. 2019-023829 [Patent Document 3] Japanese Patent Application Publication No. 2019-046232 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional technologies require large-scale capital investment and system construction. Considering the recent widespread use of automatic ticket vending machines and mobile information terminals, it would be more desirable to use a simple system that allows customers to check whether or not an item contains any avoidable foods before ordering. [Means for solving the problem]

[0005] The present invention has been made in view of the above circumstances, and aims to provide a product selection method and product selection system that uses a simple system to enable a user to easily ascertain whether or not a product contains any avoidable foods before ordering the product.

[0006] In one embodiment, the above problem is solved by the solution disclosed below.

[0007] The product selection method of the present invention is directed to a user who has a mobile information terminal equipped with a ticket vending machine that sells meal tickets, a two-dimensional code provided on the ticket vending machine, and a web server, and is capable of reading the two-dimensional code and accessing a specific URL, the web server having an input form with a plurality of avoidable food names and check boxes for entering check marks, and a standard explanation form that displays the product names and food ingredients of each food and drink to be provided by issuing a ticket from the ticket vending machine, the mobile information terminal that has accessed the specific URL makes the input form readable, and the web server allows the user to enter check marks in the check boxes of the input form by operation of the user. When the entered reply form is received as data from the mobile information terminal, the system compares the repellent food data corresponding to the checked check box in the received reply form with the food ingredient data corresponding to each of the product names in the standard explanation form, and if it is determined that a specific product name among the product names has food ingredient data that matches the repellent food data, it generates an individual explanation form with a repellent food label added to the specific product name, and sends the generated individual explanation form as data to the mobile information terminal, and if it is determined that the specific product name is not among the product names, it sends the standard explanation form as data to the mobile information terminal.

[0008] This configuration allows users with food allergies to obtain useful information directly through the simple process of reading a two-dimensional code attached to the ticket machine. This prevents them from accidentally purchasing tickets for specific products, including foods they should avoid. Furthermore, this simple system allows useful information to be provided directly to users at the product sales point.

[0009] The product selection system of the present invention comprises a ticket vending machine that sells meal tickets, a two-dimensional code placed on the ticket vending machine, and a web server, and is targeted at users who have mobile information terminals that can read the two-dimensional code and access a specific URL, the web server having an input form with a plurality of avoidable food names and check boxes to enter a check, and a standard explanation form that displays the product names and food ingredients of each food and drink to be provided by issuing a ticket from the ticket vending machine, the input form is made readable by the mobile information terminal that has accessed the specific URL, and the web server allows the user to enter a check mark in the check box of the input form by operation of the user. When a reply form containing the above information is received from the mobile information terminal, the system compares the repellent food data corresponding to the checked check box in the received reply form with the food ingredient data corresponding to each of the product names in the standard explanation form, and if it is determined that a specific product name among the product names has the food ingredient data that matches the repellent food data, it generates an individual explanation form with the repellent food label added to the specific product name, and transmits the generated individual explanation form to the mobile information terminal as data, and if it is determined that the specific product name is not among the product names, it transmits the standard explanation form to the mobile information terminal as data.

[0010] This configuration allows users with food allergies to obtain useful information directly through the simple process of reading the two-dimensional code attached to the ticket vending machine. This prevents the accidental purchase of tickets for specific products, including foods that they should avoid. Furthermore, the useful information can be provided directly to users at the product sales location using existing ticket vending machines.

[0011] For example, when the Web server transmits the individual explanation form to the mobile information terminal, it transmits a sales halt signal corresponding to the specific product name with the repellent food indication added in the individual explanation form to the ticket vending machine. With this configuration, even if a user knows whether or not a repellent food is present before ordering a product, and then accidentally presses the specific product selection button, it is possible to prevent the user from accidentally purchasing a ticket for a specific product that includes the repellent food.

[0012] The product selection method of the present invention is aimed at users who have a mobile information terminal that is equipped with a two-dimensional code placed in a building and a web server and can read the two-dimensional code and access a specific URL, and the web server has an input form with a plurality of repulsive food names and check boxes to be checked, and a standard explanation form that displays the product names and food ingredients of each of the foods and beverages served in the building, and the mobile information terminal that accesses the specific URL makes the input form readable, and when the web server receives a reply form from the mobile information terminal in which the check boxes of the input form have been checked by the user's operation, it compares the repulsive food data corresponding to the checked check boxes in the received reply form with the food ingredient data corresponding to each of the product names in the standard explanation form, and if it determines that a specific product name among the product names has food ingredient data that matches the repulsive food data, it generates an individual explanation form in which a repulsive food label has been added to the specific product name, and sends the generated individual explanation form as data to the mobile information terminal, and if it determines that the specific product name is not among the product names, it sends the standard explanation form as data to the mobile information terminal.

[0013] This configuration allows customers with food allergies to obtain useful information directly through the simple process of scanning two-dimensional codes placed on tables, counters, or other seats in the store. This allows customers to easily find out whether or not there are any allergic foods before ordering. Furthermore, this simple system allows useful information to be provided directly to customers at the product delivery location.

[0014] The product selection system of the present invention is equipped with a two-dimensional code placed in a building and a web server, and is targeted at users who have a mobile information terminal that can read the two-dimensional code and access a specific URL. The web server has an input form with multiple repulsive food names and check boxes to be checked, and a standard explanation form that displays the product names and food ingredients of each food and drink served in the building. The mobile information terminal that accesses the specific URL makes the input form readable. When the web server receives a reply form from the mobile information terminal with the check box of the input form checked by the user, the web server compares the repulsive food data corresponding to the checked check box in the received reply form with the food ingredient data corresponding to each of the product names in the standard explanation form. If the web server determines that a specific product name among the product names has food ingredient data that matches the repulsive food data, it generates an individual explanation form with a repulsive food label added to the specific product name, and sends the generated individual explanation form to the mobile information terminal. If the web server determines that the specific product name is not among the product names, it sends the standard explanation form to the mobile information terminal.

[0015] This configuration allows customers with food allergies to obtain useful information directly through the simple process of scanning two-dimensional codes placed on tables, counters, or other seats in the store. This allows customers to easily find out whether or not there are any allergic foods before ordering. Furthermore, this simple system allows useful information to be provided directly to customers at the product delivery location. [Effects of the Invention]

[0016] According to the present invention, useful information for customers with food allergies can be obtained directly in the store through a simple procedure of scanning a two-dimensional code. This allows customers to easily ascertain whether or not a product contains any allergic foods before ordering. Furthermore, this simple system can provide useful information directly to customers at the product supply location. This prevents customers from accidentally purchasing allergic foods, gastrointestinal diseases, or foods that are halal.

[0017] According to the present invention, it is possible to enhance the provision of necessary information such as food ingredients in products in buildings including not only accommodation facilities such as hotels and inns, but also restaurants, food courts, bento shops, cake shops, bakeries, cafes, izakayas, bars, and other stores that can serve food and drink.

[0019] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, the building 9 is a store, eatery, restaurant, food court, lunch box shop, cake shop, bakery, cafe, izakaya, bar, inn, hotel, train station, airport, university, government building, public facility, etc. The product in this embodiment is food and drink, including dishes served at meals. This embodiment is targeted at users who have a mobile information terminal 21 that is equipped with a two-dimensional code 4 and a web server 5 and can read the two-dimensional code 4 to access a specific URL. In all drawings describing this embodiment, components having the same functions are designated by the same reference numerals, and repeated explanations may be omitted.

[0020] This embodiment includes a web server 5 that can access the Internet 6. The web server 5 has HTTP server software for performing HTTP communication. The web server 5 has, as web content, an input form 11 having a plurality of avoided food names and a check box 11a for checking, a standard explanation form 13 displaying the product name and food ingredients of each food and drink, including dishes, served in the building 9, and an individual explanation form generation program for generating an individual explanation form 14, and the web content including these, and the web content generation program. A commercially available personal computer can be used as the web server 5.

[0021] The Web server 5 has a computer, an input form generation program, and an explanation form generation program that run on the computer. The computer of the Web server 5 has a built-in CPU and database. In addition, input means such as a keyboard and mouse, and output means such as a display device and printer are connected to the computer of the Web server 5 as needed. As a Web application, Java (registered trademark), PHP, or other known Web applications can be applied. The Web application can be a commercially available product, free software, or a custom-specified product.

[0022] The user has a mobile information terminal 21 that can access a specific URL by reading the two-dimensional code 4. The mobile information terminal 21 can be a smartphone, a tablet personal computer, a laptop personal computer, a personal data assistant, a mobile phone with a camera, or any other known mobile information terminal.

[0023] This embodiment includes a two-dimensional code 4. The two-dimensional code 4 may be a QR code (registered trademark), a matrix type two-dimensional code, or any other known two-dimensional code.

[0024] [Example 1] 1 is a schematic diagram showing a product selection system 1A(1) of the first example. In the first example, a ticket vending machine 2 capable of selling meal tickets is installed in a building 9 that has restaurants, a food court, etc., and a two-dimensional code 4 is provided on the ticket vending machine 2.

[0025] The ticket vending machine 2 has a product selection section 2a, a deposit section 2b, and a meal ticket dispenser 2c. The product selection section 2a is a touch panel liquid crystal display or a matrix of product selection buttons. The deposit section 2b accepts one or more of the following: banknotes, coins, or electronic money. The meal ticket dispenser 2c is an outlet for meal tickets or meal exchange cards.

[0026] For example, a sticker, seal, or nameplate showing the unique name of the ticket vending machine is provided on the front of the ticket vending machine 2. Also, a sticker, seal, or nameplate showing a two-dimensional code 4 indicating a specific URL linked to the unique identification information of the ticket vending machine 2 is provided.

[0027] The web server 5 is located inside the building 9. The user has a mobile information terminal 21 that can read the two-dimensional code 4 with a built-in camera and access the specific URL, and by self-declaring the avoidable foods using the mobile information terminal 21, the user can find out whether or not the specific product contains the avoidable foods before ordering the product.

[0028] If the ticket vending machine 2 and the Web server 5 can be connected via a wired connection, the ticket vending machine 2 can be easily controlled by the Web server 5 by connecting a signal line, parallel cable, coaxial cable, control cable, LAN cable, or other known signal line to the control board attached to the Web server 5 and connecting it to a controller built into the ticket vending machine 2 or an external programmable logic controller (PLC).

[0029] If the ticket vending machine 2 and the web server 5 are capable of wireless connection, the ticket vending machine 2 can be communication-controlled by a communication control unit attached to the web server 5. The wireless communication standard used by the communication control unit is a standard that allows access to the Internet 6, and can be compliant with wireless LAN, Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), SIGFOX (registered trademark), LoRa (registered trademark), NB-IoT, LPWA, or other known wireless communication standards. Note that, in addition to the above configuration, the ticket vending machine 2 may also be a standalone type that is not signal-connected to external devices.

[0030] [Example 2] 2 is a schematic diagram showing a product selection system 1B(1) of the second example. In the second example, a building 9 that includes a restaurant, a food court, etc. is equipped with a plurality of seats 3 such as tables and counters, and each seat 3 is provided with a two-dimensional code 4.

[0031] The web server 5 is located inside the building 9. The user has a mobile information terminal 21 that can read the two-dimensional code 4 with a built-in camera and access the specific URL, and by self-declaring the avoidable foods using the mobile information terminal 21, the user can find out whether or not the specific product contains the avoidable foods before ordering the product.

[0032] As an example, the two-dimensional code 4 is a card stand, and has a print, sticker, seal or nameplate indicating the card's unique name or seat number.

[0033] Next, the product selection procedure according to this embodiment will be described below.

[0034] Fig. 3A is a diagram showing an example of an input form 11 according to this embodiment. Fig. 3B is a diagram showing an example of a reply form 12 corresponding to the input form 11. Fig. 4A is a diagram showing an example of a standard explanation form 13 according to this embodiment. Fig. 4B is a diagram showing an example of an individual explanation form 14 corresponding to the standard explanation form 13. Fig. 5 is a flowchart showing an outline of a product selection procedure according to this embodiment.

[0035] [Product selection procedure] In step S1 of Fig. 5, the web server 5 prepares an input form 11 and a standard explanation form 13 for products such as food and drink served in a building 9 that has a restaurant, a food court, etc. Note that the operator of the building 9 or a contractor may prepare the input form 11 and the standard explanation form 13. Once the input form 11 and the standard explanation form 13 are prepared, the process proceeds to step S2.

[0036] 5, the Web server 5 uploads the input form 11 to the Internet 6. In addition to the above, a standard explanation form 13 may be uploaded to the Internet 6.

[0037] In step S2A of Fig. 5, the user uses the mobile information terminal 21 to read the two-dimensional code 4 with the built-in camera of the mobile information terminal 21 and access the specific URL. Then, the user checks the input form 11 displayed on the screen of the mobile information terminal 21, and replies by checking the check box 11a to declare the avoided foods themselves. It is also possible for the user not to declare the avoided foods themselves. Here, if the user does not declare the avoided foods themselves, they reply without checking the check box 11a.

[0038] As an example, as shown in FIG. 3A, a proper name display relating to ticket machine 2 or seat 3 is displayed at the top of input form 11. As an example, an announcement is displayed below the proper name display saying, "Please check the food you cannot eat and press the send button." As an example, a send button 11b is displayed at the bottom of input form 11.

[0039] As an example, check box 11a indicates specific ingredients that are allergens, such as eggs, milk, wheat, peanuts, shrimp, buckwheat, crab, salmon roe, kiwi fruit, walnuts, soybeans, bananas, yams, cashew nuts, peaches, sesame, mackerel, salmon, squid, chicken, apples, matsutake mushrooms, abalone, oranges, beef, gelatin, pork, almonds, and other known allergenic foods.

[0040] When the user checks the check box 11a to declare the avoided food and replies, for example, a reply form 12 shown in Fig. 3B is displayed on the screen of the mobile information terminal 21. For example, a proper name display is displayed at the top of the reply form 12.

[0041] For example, if the food to be avoided by the user is "eggs," the user checks "eggs" to display checked display 12a, and when the user presses send button 11b to reply, send button 11b becomes sent display 12b. The checked display 12a may be one, two or more, or zero.

[0042] In step S3 of Figure 5, the Web server 5 receives the reply form 12 and compares the avoided food data corresponding to the checked boxes with the checked indicators 12a in the received reply form 12 with the food ingredient data corresponding to each product name in the already created standard explanation form 13. Once the comparison is complete, the process proceeds to step S4. The Web server 5 may compare one, two or more, or even none of the avoided food data.

[0043] In step S4 of Figure 5, the Web server 5 determines whether a specific product name among the product names has food ingredient data that matches the avoided food data of the checked display 12a. If the Web server 5 determines that the specific product name contains an avoided food, it proceeds to step S6. On the other hand, if the Web server 5 determines that the specific product name does not contain an avoided food, it proceeds to step S5.

[0044] In step S4 of Figure 5, if the Web server 5 determines that none of the product names on the ticket vending machine 2 contain any repellent foods, the process proceeds to step S5, and the Web server 5 transmits the standard explanation form 13 to the mobile information terminal 21.

[0045] In step S4 of Figure 5, when the Web server 5 determines that the specific product name of the ticket vending machine 2 contains an aversive food, the process transitions to step S6, in which the Web server 5 generates an individual explanation form 14 and transmits the generated individual explanation form 14 to the mobile information terminal 21.

[0046] 4A is a diagram showing an example of the standard explanation form 13 when the food served in the building 9 is curry. As an example, a proper name display is displayed at the top of the standard explanation form 13.

[0047] The standard explanation form 13 is divided into sections for each product name, and from top to bottom, a product name display 13a, a product appearance display 13b, and an ingredient display 13c are displayed. The standard explanation form 13 corresponds to, for example, meals sold by the ticket vending machine 2, and is displayed on the screen of the mobile information terminal 21.

[0048] 4B is a diagram showing an example of the individual explanation form 14. As an example, a proper name display is displayed at the top of the individual explanation form 14.

[0049] As shown in FIG. 4B, for example, when the name of a specific product having a repellent food is "omelette curry" and the repellent food is "egg," repellent food display 14a is displayed over product appearance display 13b.

[0050] As an example, the repellent food marking 14a displays an announcement saying "Contains eggs." As an example, the repellent food marking 14a is displayed by overwriting the product name marking 13a with one or more of the following: strikethrough text, shading text, or red text. This allows the user to visually recognize the repellent food marking 14a. Known software technology or known image processing technology can be applied to the repellent food marking 14a.

[0051] In step S6A of FIG. 5, the mobile information terminal 21 receives the individual explanation form 14 or the standard explanation form 13. This configuration allows the user to check whether or not a product contains any repellent foods using the user's own mobile information terminal 21 before ordering. The user then selects the products of their choice, excluding specific products marked with the repellent food label 14a, and purchases the products by selecting a known payment method (electronic money, credit, prepaid card, or cash). This configuration allows the necessary information to be provided to the user at the product delivery location using a simple system. This configuration prevents users from accidentally purchasing specific products containing repellent foods.

[0052] Step S7 can be provided following step S6. In step S7 of Figure 5, the Web server 5 performs control to disable selection of the specific product. In step S7, the Web server 5 switches the display of the specific product in the product selection unit 2a of the ticket vending machine 2 to a discontinued product display. Alternatively, the Web server 5 switches the display of the specific product in the individual explanation form 14 to a discontinued product display.

[0053] As an example, the discontinued product display may be an announcement saying "Sales have been discontinued." Alternatively, the discontinued product display may be overwritten with one or more of a strikethrough, a shaded area, or a red color. As an example, the discontinued product display and the sold-out product display may be displayed using the same processing circuit. With this configuration, even if a user mistakenly selects a specific product despite knowing whether or not the product contains a repulsive food before ordering, the user can be prevented from accidentally purchasing the specific product containing the repulsive food.

[0054] In addition to the above-described embodiment, when a user reads the two-dimensional code 4 using the mobile information terminal 21 and accesses a specific URL, a banner linking to the website of the building 9 such as a hotel or restaurant or the website of the company operating the building 9 can be displayed. Also, if necessary, a dedicated application program that displays the location information of the building 9 such as a hotel or restaurant and the standard explanation form 13 can be pre-installed in the mobile information terminal 21. This allows the user to check in advance the location information of the building 9 such as a hotel or restaurant, and the ingredient information of the dishes, food, drinks, and other products that will be served.

[0055] The avoided foods mentioned above are, by way of example, foods that cause food allergies. However, avoided foods are not limited to foods that cause food allergies. It is also possible to accommodate cases where each user has a food allergy as well as religious reasons, illness, taste preferences, etc. The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the present invention.
