2. Description of the Related Art In eateries such as cafeterias, food courts, and restaurants, menus, such as paper or signboards, displaying product items to be offered and information regarding the products are arranged for viewing by users of the restaurant. Restaurants are required to display on their menus that the products are sold out or that the menu will be changed, depending on the sales of the products. Therefore, on paper or signboard menus, the display can be changed by directly rewriting the notation, or by pasting handwritten or printed paper or sheets on top of the menu to change the notation in the relevant part. was. However, with such paper or signboard menus, it is necessary to take time and effort to change the display. Additionally, if the menu is located far from the kitchen, you will need to move to the menu each time you make a change, or if multiple menus are located in multiple locations, you will need to make changes individually. There was a need for improved convenience.

In recent years, display systems (digital signage) that display such menus on display devices such as liquid crystal displays and electronic paper have been used. Patent Document 1 discloses a display system that includes electronic paper that displays a cafeteria menu and a management device that changes the display content of this electronic paper via a wireless device. In the display system of Patent Document 1, when a user inputs to the management device that the restaurant menu is sold out or has been changed, the management device changes the contents of the electronic paper. By using such a display system, the display can be changed relatively more easily than with paper or signboard menus.

Japanese Patent Application Publication No. 2015-191089

Here, in restaurants, staff members who cook, serve, serve customers, etc. are often involved in changing the display of the menu screen, so changing the display of the menu screen is carried out concurrently with other duties. Furthermore, during busy hours at a restaurant, there may not be enough work time to change the display. Furthermore, the display of the menu screen may be changed by a person who is not accustomed to operating electronic devices such as digital signage. On the other hand, in Patent Document 1, when a cafeteria menu item is sold out, by clicking on the "Sales" field on the input screen using a mouse, the settings for sales information can be changed from "Sales" to "Sales". We use a toggle-type change method to change the item to ``Sold Out''. Furthermore, in Patent Document 1, when a change in the cafeteria menu occurs, the change is made by inputting the changed menu name, price, nutritional value, etc. using a keyboard. With the technology of Patent Document 1, it is difficult to understand the operation location and operation details when changing to sold out, and it is necessary to input characters when changing the menu, and the menu screen is difficult to understand. It was difficult to say that the operability when changing the display was sufficient.

The present invention has been made in view of the above problems. That is, in one aspect, the present invention aims to enable intuitive and simple operation in a display system and reduce operational errors.

In one aspect of the present invention, the information processing device may be the information processing device in a display system including a first display device, a second display device, and an information processing device. The information processing device may include a presentation section, a selection reception section, and a change control section. The presentation unit displays a static image representing static information indicating quasi-statically changing information or unchanging information about the item, or a dynamic image representing dynamic information indicating dynamically changing information about the item. A presentation screen on which candidate images including the candidate images are arranged may be presented on the first display device. The selection reception unit is a placement area in which the static image and the dynamic image can be placed from among the candidate images on the presentation screen displayed on the first display device, and A selection request for selecting an image to be placed in the placement area provided on a menu screen displayed on the device may be accepted. In response to the selection request, the change control unit generates layout information indicating a relationship between the placement area of the menu screen and the placement image including the static image or the dynamic image placed in the placement area. In addition, changing of the layout information of the menu screen used to control display of the menu screen on the second display device may be controlled.

According to one aspect of the present invention, intuitive and simple operation is possible in the display system, and operation errors can be reduced.

In this embodiment, the menu screen 710 is displayed as a web page. A web page is composed of, for example, an HTML file written in HTML (HyperText Markup Language). The HTML file describes information regarding the content of the document displayed on the menu screen, font size, font, color, etc. The HTML file also specifies the image to be displayed on the menu screen, the image display size (width, height), display position (left alignment, center alignment, right alignment, etc.), display coordinates (X coordinate, Y coordinate, etc.). ) etc. Describe information regarding the placement area. Information regarding these images can be specified by, for example, the src attribute, height attribute, width attribute, align attribute, etc. of the img tag. Alternatively, it can be specified by the position property using a style sheet. Alternatively, a web page is a combination of a structured document file written in a markup language such as HTML, XML (Extensible Markup Language), or XHTML (Extensible HyperText Markup Language), and a style sheet file such as CSS (Cascading Style Sheets). It may be configured by a combination. In this way, the layout information (for example, the layout information of the menu screen 710) is information used for display control or display of the menu screen 710 on the display unit 330 by the receiving device 300. Note that a selection screen 720, a presentation screen 730, and a management screen 740, which will be described later, are also displayed as web pages in the same way as the menu screen 710.

In this embodiment, the selection device 200, the reception device 300, and the management device 400 perform display control on display units 230, 330, and 430, respectively.

In this embodiment, the layout information includes at least information regarding a placement area provided on a web page as described above and an image placed in this placement area. Further, the layout information may include information regarding characters displayed on the web page. The layout information is described in layout files such as HTML files, XML files, XHTML files, and style sheet files. The layout storage units 211, 311, and 411 store layout information by storing this layout file. Note that the number of arrangement areas arranged on the menu screen is not particularly limited and may be one or more, but is usually two or more. By having two or more placement areas, a list of multiple images placed in the placement areas can be displayed on the menu screen. In this embodiment, a case will be exemplified in which the number of placement areas arranged on the menu screen is four.

<Image storage section>
The image storage units 212, 312, and 412 can store image data of images displayed on the menu screen 710, selection screen 720, presentation screen 730, and management screen 740. Although the image data is not particularly limited, for example, image files in file formats such as jpg, png, gif, and bmp can be used. File names are individually assigned to the image data, and by writing the file names in the layout file, images of the corresponding image data can be displayed in a predetermined arrangement area. Images displayed on the menu screen 710, selection screen 720, presentation screen 730, and management screen 740 include static images and dynamic images. When static images and dynamic images are not particularly distinguished, they are collectively referred to as arranged images.

A static image is an image that represents static information that indicates quasi-statically changing or non-changing information about an item. Information that does not change refers to information that does not change over time, and refers to information specific to an item or information common to a group of items included in the item. Such static information includes, for example, the name of the item, the classification for categorizing the item, and the like. When the item is a product (food) provided in a cafeteria, examples of classification include food types such as Japanese food, Western food, Chinese food, curry, ramen, udon, soba, lunch, and health food. Information that changes quasi-statically refers to information that differs from item to individual, information that changes to a small degree, and information that changes over a span of several days or more. Such static information includes, for example, an image of the item's appearance, allergy information, nutritional information (energy, protein, lipid, carbohydrate, cholesterol, dietary fiber, salt equivalent, minerals, vitamins, etc.), allergen information, Examples include country of origin information, producer information, list price, etc. The static image may represent one type of static information alone, or may represent a combination of two or more types of static information. Among these, as the static image, it is preferable to display the name of the item or an image of the external appearance, and it is more preferable to display both the name of the item and the image of the external appearance. This appeals to the visual sense of the person viewing the menu screen, strengthens the impression of the item, and contributes to the person viewing the menu screen deciding whether to select that item from among multiple items. I can do it.

A dynamic image is an image that represents dynamic information that indicates dynamically changing information about an item. Dynamically changing information refers to information that changes over a span of seconds, minutes, hours, days, etc. Such dynamic information includes, for example, the sold-out status, preparation status, discount status, number of remaining items, number of items in stock, etc. of the item. The dynamic image may represent one type of dynamic information alone, or may represent a combination of two or more types of dynamic information. Among these, it is preferable for the dynamic image to display the sold-out status of the item. As a result, by reflecting the sales status and sold-out status of items, which change over time, on the menu screen, a person viewing the menu screen can contribute to judgment when selecting an item in real time. Therefore, for example, when displaying food provided at a cafeteria on a menu screen, a person who is waiting in line before ordering food or ordering food may see the menu screen and notice that the food is sold out. Knowing the condition can help you decide what food to order. In other words, when a sold-out status is displayed on the menu screen, the person who is waiting and watching the menu screen immediately switches the food to be ordered to another item other than the food for which the sold-out status is displayed. be able to.

[1-4. screen structure]
Here, the screen configurations of the menu screen 710, selection screen 720, presentation screen 730, and management screen 740 in the display system 100 of this embodiment will be described with reference to FIGS. 3 to 10.

In this case, the amount of information included in one screen of the menu screen 710 increases, and all images displayed on the menu screen 710 can be viewed at a glance, making it possible to quickly grasp the information included in the menu screen 710. . Further, a portion of the entire menu screen 710 may be scroll-displayed on one screen of the display unit 330. In this case, for example, the entire menu screen 710 can be displayed by enlarging a portion included in the menu screen 710 and displaying the displayed portion continuously or intermittently while switching the displayed portion. In this case, since the image displayed on the display section 330 is displayed larger than when the entire menu screen 710 is displayed on one screen of the display section 330, the visibility of the image can be increased. In this embodiment, the entire menu screen 710 is displayed on one screen of the display unit 330, for example.

<Menu screen>
As shown in FIG. 3, on the menu screen 710, static images 610a to 610d are arranged in arrangement areas 711a to 711d, respectively. Static images 610a-610d include item names 611a-611d, respectively, as static information indicating information about the items that does not change over time. Further, the static images 610a to 610d each include images 612a to 612d of the external appearance of the item as static information indicating quasi-statically changing information about the item. Here, among the four arrangement areas 711a to 711d provided in a 2×2 grid, the upper left arrangement area 711a has the words "Refreshing Boiled Eggplant and Chicken" as the item name 611a. A static image 610a including a photographic image of an eggplant and a lightly boiled chicken is arranged as an image 612a of the appearance of the item. The same applies to the other three arrangement areas 711b to 711d. Note that in this specification, "X×Y" refers to a state in which X columns are arranged horizontally and Y columns are arranged vertically.

Furthermore, in addition to the arrangement areas 711a to 711d and the arrangement images arranged therein, the menu screen 710 can display characters, figures, symbols, images, and the like. In the menu screen 710 of this embodiment, text information such as the year, month, day, day of the week, and category is displayed at the top of the screen. The classification is, for example, a classification for categorizing the menu screen 710, such as breakfast, lunch, dinner, night snack, overtime meal, etc. By displaying such information, the person viewing the menu screen 710 can recognize the current date and time and what information the menu screen 710 is displaying. Such a display can be similarly performed on the selection screen 720 and the management screen 740.

Note that although the present embodiment has exemplified the case where the four arrangement areas 711a to 711d are provided in a 2×2 grid shape on the menu screen 710, the arrangement areas are not limited to this. The number of arrangement areas displayed on the menu screen 710 can be set as appropriate depending on the size and resolution of the menu screen 710 and the display device 30b, and is not particularly limited, but is usually 4 or more, preferably 6 or more, and more preferably 4 or more. is 8 or more, more preferably 9 or more, particularly preferably 12 or more, and usually 50 or less, preferably 30 or less, more preferably 20 or less, still more preferably 15 or less. Further, the arrangement method of the arrangement area can be set as appropriate depending on the number of arrangement areas, and the size, resolution, and aspect ratio of the menu screen 710 and the display device 30b, and is not particularly limited. For example, 1×4, Examples include 2×3, 2×4, 3×3, 3×4, 4×4, 4×5, 5×5, 5×6, etc. A placement area can be similarly provided on the selection screen 720, which will be described later.

The menu screen 710 can display the layout images arranged in the layout areas 711a to 711d changed according to an instruction to change the layout information, which will be described later. Specifically, the menu screen 710 can display static images in placement areas 711a to 711d other than static images 610a to 610d originally placed in placement areas 711a to 711d. For example, as shown in FIG. 4, a static image 610f representing "chilled shrimp tempura grated udon" may be displayed in the placement area 711a instead of a static image 610a representing "refreshingly simmered eggplant and chicken". can. Similar to the static images 610a to 610d, this static image 610f also includes the words "chilled shrimp tempura grated udon" as the item name 611f, and a photographic image of chilled shrimp tempura grated udon as the image 612f of the appearance of the item. Contains. Furthermore, the menu screen 710 can display dynamic images in the arrangement areas 711a to 711d. For example, as shown in FIG. 5, a static image 610a representing "refreshing boiled eggplant and chicken" is displayed semitransparently in the arrangement area 711a, and a dynamic image 620a representing "sold out" is overlaid. can be displayed.

<Management device processing>
In the management device 400, first, the registration screen providing unit 422 displays the management screen 740 (step S301).

Next, with the management screen 740 displayed, the registration reception unit 423 accepts a registration request for a layout image (step S302).
In step S302, if a request to register a placed image is not made, the process advances to step S306.

If a request for registration of a placed image is made, the registration accepting unit 423 transmits the registration request accepted in step S302 to the storage instructing unit 424 (step S303). Then, the storage instruction unit 424 transmits an image data storage instruction to the storage unit 425 in response to the registration request transmitted from the registration reception unit 423 (step S304). At this time, the storage instruction unit 424 transmits a change instruction to change the layout information to the storage unit 425 in response to the registration request. Further, the storage unit 425 stores the image data in the image storage unit 412 in response to the image data storage instruction transmitted from the storage instruction unit 424 (step S305). Furthermore, the storage unit 425 changes the layout information stored in the layout storage unit 411 in response to a change instruction sent from the storage instruction unit 424.

Next, the changing unit 421 determines whether an instruction to change the layout information has been received from the change instructing unit 223 (step S306).
If no instruction to change the layout information is given in step S306, the process advances to step S308.

When an instruction to change the layout information is given, the change unit 421 changes the layout information stored in the layout storage unit 411 in accordance with the change instruction transmitted from the change instruction unit 223 (step S307).

Further, the transfer unit 426 compares and determines the waiting time T and the polling time T ₀ (step S308). The waiting time T is set to 0 when the system 100 starts operating, and increases as time passes while the system 100 is operating. If the waiting time T is longer than the polling time T ₀ , the transfer unit 426 transfers the layout information and image data to the output unit 321 (step S309). At this time, the waiting time T is reset to zero. On the other hand, if the waiting time T is less than the polling time T ₀ , the flow ends without transferring the layout information and image data, and the management screen is displayed (step S301).

Note that in the above description, the case where the processing of steps S301 to S305, the processing of steps S306 to S307, and the processing of steps S308 to S309 are performed in this order is exemplified. The order of these three processes performed by the management device 400 is not limited to the above-mentioned order, and may be changed.
