In the case of using the above-mentioned passenger seat terminal instead of such a large and large-sized menu printed material, it is important to improve the usability of the passenger seat terminal. The display area of a tablet computer is extremely limited, and very little information can be displayed on a single screen. However, a variety of information can be displayed while switching the screen by a computer program. Utilizing this characteristic, a variety of attribute information is added to each product item to create a database of menus, and a passenger terminal can be configured so that users can easily select products through easy-to-understand multi-level classification search can do.

  Such a passenger terminal can further realize various functions that could not be considered when selecting a product while turning a menu page of a printed matter by utilizing the information processing function of the tablet computer. For example, every time a product is ordered, the total price of the products ordered so far can be displayed. The customer can select the products to be additionally ordered while looking at the total amount displayed and considering his / her budget amount. Similarly, the total calorie intake (calorie) of the ordered product can be displayed. By doing so, it is possible to select a product to be additionally ordered while looking at the total calorie displayed and considering the upper limit calorie intake.

  If this is further evolved and a mode for displaying only products that can be ordered within the range up to the upper limit intake calorie set by the user is provided, the enjoyment of product selection will increase. For example, there are customers who feel that it is convenient to save the trouble of operation by releasing the troublesomeness of being able to show products that are out of the first choice by just the amount of heat without seeing from among many products. Let's go. Also, some customers may appreciate the unexpected high-calorie diet that can prevent them from being tempted and overdose. People who care about calorie intake can eat and drink with confidence. Also, in complex facilities such as karaoke stores, there will be some customers who are getting more excited about singing and playing with the goal of consuming the heat consumed by eating and drinking. The present invention was created with such an intention.

It is possible to accept the operation input of the store clerk, assign the seat when the customer enters the store, and pay at the attached cash register terminal when leaving the store.

  The kitchen terminal 3 is also a client computer composed of a general-purpose personal computer, and performs data communication with the store computer 1 through the LAN 5 as appropriate. A printer is attached, and based on the order contents, an order receipt including the order contents such as the seat number, its item, and quantity is printed out. It has a user interface that accepts the operation input of the clerk in charge of cooking and serving and presents information, presents the order details such as the seat number ordered, its items, number of items, etc. You may comprise so that operation input may be received.

=== Configuration of the passenger seat terminal 4 ===
The passenger seat terminal 4 includes a user interface mainly composed of a touch panel in which a liquid crystal display and a touch sensor are stacked, and various image information displayed on the touch panel is stored in an external storage such as a built-in flash memory or a hard disk device. ing.

  The remote control unit controls the entire system including CPU, RAM, ROM, video RAM, etc., and develops various image information and character information into video RAM based on the input information to the touch panel. The LCD driver is driven to display appropriate information on the touch panel.

  In addition, information on foods and drinks that can be provided in this store is stored in the external memory and managed as a menu database. This is updated to communicate with the store computer 1 at appropriate occasions and to synchronize.

  The remote control control unit searches and presents food item information desired by the user from the menu database through dialogue with the user via the touch panel, or generates an order signal upon receiving the user's order input. To the store computer 1.

=== Configuration of menu database ===
As shown in FIG. 2, the menu database attached to the store computer 1 and the passenger seat terminal includes items of each item for items of food and drink that can be provided in the store (identified by the item ID assigned to each). Various attribute items such as name, genre, fee, main material, calorie intake (calorie), and photo location information are described, and item ID is stored and managed as key information.

  The item information contained in these menu databases is entered and updated by the store clerk and the store owner at appropriate occasions such as before and after maintenance hours via an appropriate user interface provided in the store computer 1.

It is also possible to configure to update the menu database upon receiving data distribution.

=== Registered member and login ===
A customer who uses the heat management function according to the present embodiment is a member who has previously registered member information (name, contact information, nickname, face photo, etc.) including his / her personal information with the business operator. For example, Japanese Patent No. 3629450 discloses a mechanism in which a member and a non-member share a guest room terminal placed in the guest room and the member logs in to use the member dedicated service function.

  The members of this embodiment are given a non-contact type IC card from the business. A unique card ID is assigned to the IC card and is recorded in a non-rewritable memory built in the IC card. The business operator identifies each member by using the card ID as a member ID, stores member information associated with the member ID in the customer management server, and manages it as a customer management database. The customer management server is a general-purpose server device operated by a business operator, and is configured to be capable of data communication with the store computer 1 and the customer seat terminal 4 via a network.

  When the member is seated, the login process is performed by appropriately operating the passenger seat terminal 4 installed in the seat. For example, according to the guidance display on the top menu screen illustrated in FIG. 3 (in the example of FIG. 3, when the “add member” button is instructed, a message is displayed so as to hold the member IC card over a predetermined card reader unit), When the IC card possessed is held over the antenna of the card interface, the passenger seat terminal 4 reads the card ID and transfers it to the customer management server. The passenger seat terminal 4 temporarily stores the member information returned from the customer management server in the memory area corresponding to the member ID, and completes the login process. That is, the passenger seat terminal 4 secures a memory area corresponding to each logged-in member and manages each member information individually.

  Based on the member information, the passenger seat terminal 4 displays a list of appropriate information such as the nickname and face photo of the logged-in member on the touch panel. When the logged-in member designates himself / herself by a predetermined operation such as selecting and instructing his / her nickname or face photo from the displayed one, the screen shifts to a menu screen dedicated to each member.

  For example, FIG. 4 illustrates a menu screen dedicated to Mr. A. When the member inputs each instruction via a dedicated menu screen, a command corresponding to the instruction content is transmitted to an appropriate apparatus with the member ID. Also, it is possible to use member-specific service functions by storing frequently ordered favorite items, past order history, etc. in the memory area corresponding to the member ID or additionally storing it in the member information of the customer management server. Has been.

  In the example of FIG. 4, a button for starting a member-dedicated service function that is not displayed on the top menu screen (FIG. 3) common to all users, such as a “favorite” button and a “reiki” button, is displayed. . If these instructions are input, member-specific service functions such as selection of products from favorite items and order history can be used. Members can activate and use the heat management function described below.

  When each logged-in member uses the audience terminal 4 after another user, he / she indicates himself / herself from the nickname and face photo of the logged-in member listed on a part of the touch panel. Select and direct to the menu screen for your own use. The passenger seat terminal 4 refers to the memory area for the login member selected each time, and displays the menu screen dedicated to each member based on the member information.

  The memory area for the login member of the passenger seat terminal 4 is released when the member or the store clerk performs a predetermined logout process for the member when leaving the store. At that time, the memory contents are appropriately transmitted to the customer management server, and the member information managed by the server is updated.

  Non-members and non-logged-in members can use the top menu screen of FIG. 3 to perform operation input. Naturally, the instruction command corresponding to the operation input is not accompanied by a member ID. Sent from the passenger seat terminal 4. The member-only service cannot be activated.

=== Menu display processing by heat quantity management function ===
The logged-in member can set the upper limit of the total calorie intake today using the passenger seat terminal 4 and can activate the heat management function. For example, when the “upper calorie intake upper limit” setting button 41 is instructed and input on the top menu for members of the passenger seat terminal 4 illustrated in FIG. 4, the upper limit value of the total calorie intake can be numerically input. The upper limit value input here is stored in a memory area corresponding to the member ID. In addition, the same value as the upper limit value is set as an initial value, and the remaining amount value (a0) up to the upper limit value is stored in the member memory area.
Other logged-in members other than Mr. A can also switch to each member's dedicated menu screen as described above and set their own calorie upper limit value in the same manner, and are stored in the memory area corresponding to each member ID. The upper limit value set for each member is displayed in a list so that the upper limit value set by each member can be seen at a glance by associating it with the nickname or face photo of the logged-in member listed on the screen. It is good to keep it (see FIG. 4).

  When the intake calorie upper limit value and the remaining amount value up to the upper limit value are set, the passenger seat terminal 4 switches to the in-range menu display mode. That is, the passenger seat terminal 4 reads item information (item ID, genre, item name, fee, calorie intake, etc.) for a number of items included in the menu database. At that time, the remaining amount value a0 up to the upper limit value of the memory is referred to, and a non-display flag is attached to an item whose calorie intake is higher than the remaining amount value.

Then, based on the read item information group, members are allowed to search for items that can be appropriately ordered interactively using a touch panel display, and the search results are displayed as a list. At that time, the item without the non-display flag is set as an orderable item, and the item with the non-display flag is excluded from the search target and is not displayed on the display unit. The user is instructed to select a target item from the displayed items, and information related to the item is displayed.
Note that items with a non-display flag may also be displayed on the display unit as items to be searched for by distinguishing them from items that can be ordered by displaying them in light-colored characters or thin characters.

  As is well known, various methods can be used to search for items based on the attribute items in the menu database. For example, a search by genre of each item (see FIGS. 4 to 5) is common. Of course, a search by item name (instructing the character input button 43) or a search by specifying the item ID (instructing the order number input button 44) is also possible.

  In the example of FIGS. 4 to 5, the target item is searched by allowing the member to select and specify the genre of the food item. Here, the genre can be specified at a plurality of levels. For example, in the top menu, genres are classified into appropriate categories such as “salad”, “meat”, “fish”, “alcohol”, “soft drink”, and “dessert”, and displayed in a list. Next, when “alcohol” is selected, it is classified into “Japanese sake”, “shochu”, “wine”, and “whiskey”. Furthermore, when “wine” is selected, it is classified into “red wine”, “white wine”, and “sparkling wine”. In this way, the attribute items (genres) in the menu database are classified into a plurality of categories. One genre may be classified into a plurality of categories.

  If the member terminal 4 repeats the operation of selecting and specifying one of the displayed categories to reach any genre and selects and specifies, as shown in FIG. 5, orders included in the genre can be ordered. List items in an appropriate order. At that time, the calorie intake of each item is displayed in association with each other. In addition, the remaining portion up to the upper limit of intake calories set for the member is displayed at an appropriate position such as a header portion of the screen. In the example of FIG. 5, the item with the non-display flag is displayed in italic thin characters and is displayed separately from the orderable item, and the item cannot be selected and input.

  When a member selects and designates one of the orderable items displayed, detailed information such as photos and raw materials for that item is displayed, as illustrated in FIG. 6, as described below. Configured to order the item.

If the “exceeding upper limit menu” button 42 is instructed, an item with a high calorie intake with a non-display flag can be displayed and ordered regardless of the set upper limit value. Good.
Further, when the member does not set the upper limit value, the passenger seat terminal 4 operates in the normal menu display mode, and it goes without saying that all items that can be ordered in the menu database are displayed regardless of the calorie intake. .

=== Order processing by heat management function ===
As described above, the member performs a predetermined operation of turning and returning the page as appropriate on the touch panel display of the passenger terminal 4 while displaying the item to be ordered on the display and inputting a selection instruction (FIG. 5), the detailed information of the item is displayed (see FIG. 6). When the quantity to be ordered is specified and input on the screen on which the detailed information is displayed (61 in FIG. 6), the audience terminal 4 displays the quantity of the item ordered from the remaining amount value a0 (initial value = upper limit value) up to the upper limit value. A remaining amount value (a1) up to an upper limit value obtained by subtracting the total calorie intake (calorie intake × quantity) is calculated and displayed on the display (63 in FIG. 6).

  When the member inputs the order button 62 displayed on this screen, the passenger seat terminal 4 generates an order signal with the item ID, item name, number of orders and seat number of the item and outputs it to the store computer 1. To do. In addition, the passenger seat terminal 4 stores the remaining amount a1 up to the previously calculated upper limit value in the member memory area so as to overwrite a0.

  When this member next places another order, the total remaining calorie of the new order item is subtracted from the remaining amount value a1 up to the upper limit value, and a new remaining amount value up to the upper limit value (referred to as a2). Is calculated. When the order is completed, the calculated new remaining amount value a2 is stored so as to be overwritten on a1 of the memory. In this way, the remaining amount value up to the upper limit value is subtracted and updated every time the member places an order, with the upper limit value set by the member as an initial value.

  Here, if the remaining value exceeds the total calorie intake of the ordered item when the member specifies the quantity, a message that the upper limit is exceeded is displayed. For example, even if the calorie intake of a single item is within the range of the remaining amount value, the total calorie intake exceeds the remaining amount value by increasing the quantity. In case of exceeding the upper limit, the order may not be placed unless the quantity is reduced and kept within the range of the remaining amount, or the order is accepted after allowing the member to exceed the upper limit. It may be. For example, as illustrated in FIG. 7, a message 71 indicating that the upper limit has been exceeded is displayed, and an instruction for the order button 72 is input only when the member permits. Alternatively, the order button 72 can be instructed by an operation such as instructing the “upper limit menu” button. In this case, the user interface may be configured so that the upper limit value can be corrected.

As described above, the user interface may be configured so that a plurality of items can be ordered collectively by simply inputting an order button once after selecting a plurality of items, instead of ordering one item at a time. Even in this case, if the upper limit is exceeded in the same manner as described above, the order may not be placed unless any item or quantity is reduced, and the order button 62 can be instructed after allowing the member to allow the upper limit to be exceeded. You may comprise. Further, the upper limit value may be modified.
Of course, you may comprise so that an upper limit can be corrected anytime, eating and drinking. The customer can increase or decrease the upper limit value while taking into account the degree of fullness or the calorie digestion due to singing.

  After the order signal is transmitted or the upper limit value is corrected, the passenger seat terminal 4 executes the menu display process again based on the new upper limit value, so that an orderable item that is less than or equal to the intake calorie upper limit value is found. Display the list as you can see.

  As described above, the setting of the upper limit value and the order are set and managed for each member based on the memory area for each member. Therefore, other members can log in with their own IC cards and switch to their own member-only menu to set an upper limit of calorie intake or order within that range.

=== Other Embodiments ===
The setting of the intake calorie upper limit value may be configured such that the store clerk specifies and sets the guest seat number and the member ID at the front terminal 1 when visiting the store.
When a customer uses a passenger seat terminal alone, or when setting / managing the upper limit value of calorie intake for the entire group, the upper limit value setting or order processing may be performed without associating the member ID. In that case, a user interface may be provided in the top menu common to all users (FIG. 3) in order to activate a calorie management function such as a “calorie intake upper limit setting” button.

  According to the electronic menu ordering device described above, users can place orders within the range of the upper limit of calorie intake set by the customer, so many orders can be made unnecessarily, or products with high calorie intake can be ordered. Can be prevented. Since customers can enjoy the operation of the electronic menu device with peace of mind, the introduction of the electronic menu device can be expected to streamline the service and improve the sales efficiency of the store. In addition, the effect of increasing the number of customers who come to the store looking forward to the electronic menu device can be expected.

It is the figure which illustrated the composition of the system containing the passenger seat terminal concerning this example. It is the figure which illustrated the logic structure of the menu database. The top menu screen of the passenger seat terminal which concerns on a present Example is illustrated. The initial screen of the menu display process which concerns on a present Example is illustrated. It is an example of a menu display concerning a present Example.
