[First embodiment]
In the first embodiment, a system is described in which a display device is installed in a toilet cubicle, and when it detects that a user has entered the toilet cubicle, the display device in the toilet cubicle displays an advertisement. Furthermore, in this embodiment, in a toilet facility consisting of multiple toilet cubicles, advertisement display control is performed according to the congestion state of the toilet facility so that the user can view the advertisement, and in a toilet facility consisting of one toilet cubicle, advertisement display control that is set in advance is performed. Note that, hereinafter, a group of toilet cubicles that can be used through the same entrance/exit is considered as one toilet facility.

<Example of queue management system configuration>
1 is a diagram showing an example of the configuration of a restroom display system according to this embodiment. The restroom display system 1 includes a management server 10, and detection devices 21-1 to 21-n and display devices 23-1 to 23-n installed in restroom cubicles 22-1 to 22-n, respectively. Note that n is an integer of 2 or more, and hereinafter, when referring to any of the above, they may be abbreviated as restroom cubicle 22, detection device 21, or display device 23.
The management server 10 has a vacancy management function that manages the presence or absence of users in each toilet cubicle and information on the congestion of the toilet facility based on the results of user detection by the detection device 21 in each toilet cubicle.The management server 10 also has an advertising management function that stores video data of advertising content, information image data, etc., and distributes them to the display device 23.
The network 30 is a communication network including wired and wireless networks, and includes, for example, the Internet, a public line network, and WiFi (registered trademark).

2 is a diagram showing an example of a detection device 21 and a display device 23 installed in a toilet cubicle 22 in a toilet facility. The detection device 21 is installed in each toilet cubicle and is a device for detecting vacancy information of the toilet cubicle 22 used by a user. Here, vacancy information is information indicating the vacancy status (presence or absence of a user). For example, the detection device 21 can be a human presence sensor that detects the presence of a user in the toilet cubicle 22, or a magnetic sensor that detects the opening and closing of the door of the toilet cubicle 22. In this embodiment, a magnetic sensor is used. If the toilet cubicle 22 is a normally open type, when the magnetic sensor detects that the door of the toilet cubicle 22 is closed, it can be considered that the toilet cubicle 22 is being used by a user. On the other hand, when the magnetic sensor 22 does not detect that the door is closed (detects that the door is open), it is considered that there is no user in the toilet cubicle 22. The detection device 21 transmits the detection result of the opening and closing of the door together with the identification information of the detection device 21 to the management server 10 via the network 30. In this embodiment, the detection device 21 detects whether the door is open or closed every 5 seconds and transmits the detection results to the management server 10.

The display device 23 is a terminal that displays videos or images such as advertisements while a user is using the toilet cubicle 22. For example, a tablet computer is used as the display device 23. The display device 23 is installed on a wall or door inside the toilet cubicle. The display device 23 is configured to be able to communicate with the management server 10, and can receive and store advertisements from the management server 10. The advertisements may be still images, videos, or text data, and may also be accompanied by audio output. The display device 23 also obtains information on the congestion status of the toilet facility (hereinafter referred to as "crowding information") and information on the presence or absence of a user in the corresponding toilet cubicle 22 (the cubicle in which the display device 23 is installed) (hereinafter referred to as usage information) from the management server 10, and displays advertisements according to the congestion information and usage information.

<Example of Hardware Configuration of Management Server 10 and Display Terminal 23>
3A is a hardware configuration diagram of the management server 10. The management server 10 includes a central processing unit (CPU) 110, a read only memory (ROM) 120, a random access memory (RAM) 130, a storage device 140, and a communication device 150. The CPU 110 executes a program described below to realize the functions provided by the management server 10. The ROM 120 and the RAM 130 hold data used by the CPU 110. The storage device 140 stores a program and a database described below. The communication device 150 communicates with the detection device 21 and the display device 23 via a network 30.

Figure 3 (b) is a hardware configuration diagram of the display device 23. The display device 23 includes a CPU (Central Processing Unit) 230, a ROM (Read Only Memory) 231, a RAM (Random Access Memory) 232, a storage device 233, a communication device 235, and a display 236. The CPU 230 controls the operation of each part of the display device 23. The ROM 231 and the RAM 232 hold data used by the CPU 230. The storage device 233 stores programs and databases described below. The communication device 235 communicates with the management server 10 via the network 30. The display 236 is a display screen for displaying images including advertisements.

<Example of functional configuration of management server 10 and display device 23>
4 is a block diagram showing the functional configuration of the management server 10 and the functional configuration of the display device 23. The management server 10 includes a receiving unit 311, an updating unit 312, a congestion degree derivation unit 313, an advertisement control unit 314, and a storage unit 315 as software modules executed by the CPU 11 (functions configured by various programs being expanded in the internal memory of the CPU 110). For convenience of description, these modules may be described below as the operating subjects, but since it is the CPU 110 that actually executes these modules, the CPU 110 may also be the operating subject.

The receiving unit 311 receives data indicating the results of detection by the detection device 21 from the detection device 21 , and accepts requests from the display device 23 .
The storage unit 315 has a facility information table 316, a private room management table 317, and an advertisement table 318. Fig. 5 is a diagram showing examples of the structure of the building information table 316, the private room management table 317, and the advertisement table 318. Each table can be constructed, for example, by storing data describing the contents of records in the memory storage 140. Note that in this embodiment, the building information table 316, the private room management table 317, and the advertisement table 318 are in table format, but they are not limited to this format and may be constructed in any format as long as each data is linked.

The building information table 316 shown in Fig. 5(a) is a data table that manages information on the building in which each toilet facility is located. The building information table 316 has, for example, a building ID (identification information that can identify a building), building genre, address, business hours, maximum number of loops, initial screen, etc. as configuration items. Here, business hours are a time period defined by the opening and closing times of the building in which the toilet facility is located, and are the time periods during which the toilet facility can be used by users.
The maximum loop count indicates the upper limit of the number of loops for N pieces of advertising content data to be displayed at one time. For example, if three pieces of advertising content data are to be displayed when a user enters a toilet cubicle, in a toilet cubicle with a maximum loop count of 2, each piece of advertising content data will be displayed on the display device 23 a maximum of three times while the user is using the toilet cubicle. The initial screen is a screen that is displayed when no advertising content data is being displayed, and in this embodiment, can be registered for each building. For example, an image displaying text such as "Thank you for using the toilet cubicle in a beautiful manner" or

The cubicle management table 317 shown in Fig. 5B is a data table for managing the usage status and congestion level of each toilet cubicle. For example, the cubicle management table 317 has a sensor ID, a building ID, an area ID, a cubicle attribute, a usage status, and a congestion level as configuration items.
The sensor ID is identification information of the detection device 21 installed in the toilet cubicle. The building ID is identification information of the building in which the toilet facility is located. The cubicle attribute is information indicating attributes that limit users, such as the gender available or multi-purpose toilet, and is linked to, for example, male, female, shared, multi-purpose, etc. The tablet ID is identification information of the display device 23 installed in the toilet cubicle.
The area ID is identification information for identifying a toilet facility including a toilet cubicle. When a building has toilet facilities on each floor, an area ID is assigned to each toilet facility on each floor. In a three-floor building, when a male toilet and a female toilet are located on the north side of each floor and a male toilet, a female toilet, and a multi-purpose toilet are located on the south side of each floor, the building has a total of 15 toilet facilities, and 15 different identification information, each of which is an area ID, is stored in association with the building ID of the building.

The information indicating the usage status in the cubicle management table 317 (hereinafter, referred to as usage information) indicates whether or not a user is present in the cubicle. Here, the state where there is no user is displayed as "vacant" in text, and the state where there is a user is displayed as "in use" in text, but it is also possible to store the state where there is no user as "0" and the state where there is a user as "1". The congestion degree is information indicating the degree of congestion of the cubicle including the cubicle. In this embodiment, the congestion degree is a fraction with the number of remaining "vacant" cubicles in the cubicle as the numerator and the number of cubicles included in the cubicle as the denominator. For example, the cubicle with area ID "001" is a women's cubicle consisting of two cubicles, one of which is "vacant" and the other is "in use", so the number of remaining cubicles (congestion degree) of area ID "001" is 1/2. Therefore, the congestion degree of the two cubicles with area ID "001" is stored as "1/2".

The advertisement table 318 is a data table that manages information related to advertisements that may be displayed in the restroom display system. For each of a number of advertisements, the advertisement table 318 has the following components: information identifying the advertisement (advertisement ID), the advertiser providing the advertisement, the display period during which the advertisement is to be displayed, a building ID that identifies the building in which the advertisement is to be displayed, and advertisement content data. In this embodiment, each advertisement is a 15-second video.

The update unit 312 updates the cubicle management table 317 based on the detection result data indicating the detection result of the user received by the receiving unit 311 from the detection device 21. Since the detection result data includes the identification information of the detection device 21 and information indicating the detection result of the user, the update unit 312 identifies the toilet cubicle by referring to the identification information and updates the corresponding usage status.
The congestion degree derivation unit 313 derives the congestion degree of each toilet facility. As described above, the congestion degree is a fraction with the number of "vacant" (no users present) toilet cubicles as the numerator and the number of toilet cubicles included in the toilet facility as the denominator. After deriving the congestion degree for each area ID, the congestion degree derivation unit 313 uses the derived congestion degree to update the congestion degree of the toilet cubicle corresponding to the toilet area ID in the cubicle management table 317.

The advertisement control unit 314 communicates with the display device 23 that displays advertisements, and transmits data necessary for advertisement display to the display device 23. First, the advertisement control unit 314 distributes advertisement content data in advance to the display device 23 installed in the toilet cubicle 22 during a time period designated for each toilet facility (preferably a period when there are few users, such as late night hours or outside business hours). The display device 23 receives the advertisement content data and stores the advertisement content data in advance in the storage device 234. Here, the advertisement control unit 314 distributes three advertisement content data as advertisement content data that can be displayed by the display device 23. In addition, when the receiving unit 311 receives a request from the display device 23, the advertisement control unit 314 transmits usage information and congestion degree to the display device 23 as information necessary for the display device 23 to determine whether or not to display an advertisement.

Next, a functional configuration of the display device 23 will be described. The display device 23 includes an acquisition unit 2340, a setting unit 2341, a determination unit 2342, and a display control unit 2343 as software modules (functions configured by various programs being expanded in the internal memory of the CPU 230) executed by the CPU 230. For convenience of description, these modules may be described below as the subject of operation, but since it is the CPU 230 that actually executes these modules, the CPU 230 may also be the subject of operation.
The acquisition unit 2340 acquires from the management server 10 the usage information and congestion level held by the management server 10, information about the terminal itself, information about initial settings required for displaying the display device 23, and the like. The setting unit 2341 performs settings required for displaying on the display device 23. For example, the setting unit 2341 sets an initial screen or an upper limit number of times to loop advertisement playback.

The determination unit 2342 determines whether the corresponding toilet cubicle 22 is in use or not, and whether to loop playback or not according to the degree of congestion, based on the usage information acquired from the management server 10. In addition, the determination unit 2342 periodically acquires the usage information even after the usage is detected, and determines whether the usage information has been updated from "in use" to "vacant" in order to monitor that the user has left the cubicle.
The display control unit 2343 controls the display on the display 236. In this embodiment, while a user is not in the toilet cubicle 22, an initial screen (still image) is displayed, and when a user enters the cubicle, advertising content data (moving image) is displayed.

<Sequence for managing toilet cubicle usage>
Fig. 6 shows a sequence diagram for managing the usage status of a toilet cubicle. Each process (step) is represented as "S".
In S601, the detection device 21 installed in the toilet cubicle 22 judges whether the toilet cubicle is being used at predetermined time intervals (e.g., every 10 seconds). Here, a magnetic sensor installed on the door of the toilet cubicle is used as the detection device 21, so the detection device 21 detects whether the door of the toilet cubicle is closed or open.
In S602, the detection device 21 transmits the result of detection of the open/closed state of the door together with the identification information of the detection device 21 itself to the management server 10.

In S603, the management server 10 updates the private room management table 318 based on the detection result received from the detection device 21 and the identification information of the detection device 21.
In this embodiment, the detection device 21 transmits detection result data to the management server 10 every 10 seconds, but in addition to transmitting data periodically every 10 seconds, the detection device 21 may also be configured to transmit to the management server 10 a message indicating that the door is closed when it detects that the door is closed.

<Crowding Degree Calculation Process>
The congestion degree derivation process executed by the congestion degree derivation unit 313 in the management server 10 will be described in detail below. Fig. 7 shows a flowchart of the congestion degree derivation process. The CPU 110 of the management server 10 can realize each step by reading and executing a program capable of realizing the flowchart shown in Fig. 7.
First, in S701, the congestion degree derivation unit 313 determines an area ID to be processed. In this embodiment, the registered area IDs are processed in order. Furthermore, for example, an available time period may be registered for each area ID, and only the area IDs corresponding to the available time period may be processed, or the toilet facility corresponding to the toilet cubicle whose usage information has been updated by the update unit 312 may be processed.
In S702, the congestion degree derivation part 313 identifies the toilet cubicle 22 of the area ID to be processed, and acquires the usage information of each toilet cubicle.

In S702, the congestion degree derivation unit 313 counts the number of toilet cubicles in the area ID being processed, and sets this as the number of toilet cubicles. In addition, among the toilet cubicles in the area ID being processed, the number of toilet cubicles whose usage information is "in use" is counted, and sets this as the number of remaining cubicles. The congestion degree derivation unit 313 determines a fraction with the number of remaining cubicles as the numerator and the number of toilet cubicles as the denominator as the congestion degree corresponding to the area ID.

In S703, the congestion degree of at least one toilet cubicle corresponding to the area ID to be processed is updated with the congestion degree derived in S702.
In S705, the congestion degree derivation unit 313 determines whether there is an area ID to be processed next, and if there is an unprocessed area ID (YES), the process returns to S701, and if there is no unprocessed area ID (NO), the process is completed. In this embodiment, since the registered area ID is the processing target, in S705, the congestion degree derivation unit 313 determines that there is an unprocessed area ID as long as there is a data set corresponding to the area ID in the private room management table 317. For example, if two area IDs are registered, the congestion degree is derived alternately for the two area IDs. Here, if the management server 10 cannot access the private room management table 317, or if an instruction to end the congestion degree derivation process is given by an external operation via the communication device 150 or the CPU 110, the result of the determination in S705 is NO.
With the above, the congestion degree derivation process in the management server 10 is completed.

<Flowchart of advertisement display control process>
The advertisement display control process in the display device 23 will now be described in detail. Fig. 8 shows a flowchart of the advertisement display control process. Each step can be realized by causing the CPU 230 of the display device 23 to load and execute a program capable of realizing the flowchart shown in Fig. 8. For example, after the display device 23 and the detection device 21 are installed in a toilet cubicle, the display device 23 is turned on, and then the following flowchart is started.
In S801, the acquisition unit 2340 requests the management server 10 for information related to display control settings (hereinafter referred to as display setting information) together with the identification information of the display device 23 itself, and acquires the display setting information. In this embodiment, the display setting information acquired is information indicating the area ID, attributes, maximum loop count, and business hours corresponding to the identification information of the display device 23 itself, and image data to be used as an initial screen.

In S802, the setting unit 2341 performs settings related to advertisement display based on the display setting information acquired in S801. The setting unit 2341 sets the image data acquired as the initial screen as the initial screen, and sets the acquired maximum loop count as the loop count. In S803, the display control unit 2343 displays the image data set as the initial screen.
In S804, the acquisition unit 2340 acquires from the management server 10 the congestion level and usage information (information indicating whether the terminal is in use or available) corresponding to the terminal itself.

In S805, the determination unit 2342 refers to the usage information and determines whether the toilet cubicle set by the display device 23 itself is in use. In this embodiment, if the acquired usage information is "in use", the process proceeds to S806 and S812, and if the acquired usage information is "vacant", the process proceeds to S811.
The processes from S806 to S809 are executed on the assumption that the user remains in the toilet cubicle. In S806, the display control unit 2343 displays N pieces of advertisement content data distributed in advance on the display 236. In this embodiment, three pieces of advertisement content data are distributed in advance and stored in the storage device 234, and the display control unit 2343 sequentially plays back the three pieces of advertisement content data in random order.

In S807, the determination unit 2342 further refers to the crowdedness level to determine whether or not there are other toilet cubicles 22 in the same toilet facility as the toilet cubicle 22 corresponding to its own terminal. Specifically, the determination unit 2342 determines whether or not the denominator (number of toilet cubicles) of the fraction indicating the crowdedness level is 2 or greater. This allows the determination unit 2342 to determine whether or not the toilet facility corresponding to its own terminal is a facility that includes multiple toilet cubicles 22. If the determination unit 2342 determines that there are other cubicles in the same toilet facility, it proceeds to S808, and if it determines that there are no other cubicles, it proceeds to S809.

In S808, the determination unit 2342 determines whether or not to execute loop playback of advertisements on the display device 23 itself depending on the usage status of the other toilet cubicles. The determination unit 2342 determines whether or not to execute loop playback of advertisements based on the degree of congestion expressed by a fraction with the number of "used" toilet cubicles as the numerator and the number of toilet cubicles as the denominator. In this embodiment, the determination unit 2342 determines the congestion status based on whether the fraction indicating the degree of congestion is less than 1. If even one other cubicle is in an "empty" state, the determination unit 2342 determines to execute loop playback and proceeds to S809, whereas if all toilet cubicles in the toilet facility are in use, the determination unit 2342 determines not to execute loop playback, skips the loop playback process in S809, and proceeds to S810.
In S809, the display control unit 2343 loops the N pieces of advertising content data played back in S806. Note that the number of times to loop the advertising content data is the maximum number of times set in S802.

In parallel with the processes from S806 to S809, in S811 the determination unit 2342 monitors the exit of a user who is using the toilet cubicle 22. Specifically, the determination unit 2342 transmits a request for usage information to the management server 10 at predetermined time intervals (e.g., every 5 seconds), acquires usage information of the toilet cubicle 22 from the management server 10, and determines whether the usage information has become "vacant." If the acquired usage information indicates "vacant," the determination unit 2342 proceeds to S812.
In S812, the display control unit 2343 displays image data for the initial screen, which is the same as the initial screen displayed in S803, on the display 236. If the process proceeds from S811 to S812, the display of the advertisement is forcibly terminated and the display of the initial screen is fixed. In this embodiment, the same still image is displayed on the display 236 in S803 and S810, but different images may be displayed. For example, since S810 is displayed after the display device 23 displays an advertisement to the user, a still image including text such as "Thank you for using our service" or "Please be careful not to leave anything behind" may be displayed. However, it is preferable that the image displayed in S810 is a still image, not a moving image including changes, in order to suppress the inducement of a long stay.

In S812, the determination unit 2342 determines whether or not to complete the process. Specifically, the determination unit 2342 determines whether or not it is within the business hours of the building including the restroom facility in which the terminal is installed. If the current time is within the business hours, it is determined that the process is not to be completed and the process returns to S804, whereas if it is outside the business hours, it is determined that the process is to be completed and the process is completed.
This completes the advertisement display control process in the display device 23.

<Flow of advertising in toilet cubicles>
FIG. 9 is a diagram for explaining the flow of advertisements to be displayed. FIG. 9(a) shows the order in which advertisements are displayed when the advertisements are played in a loop, and FIG. 9(b) shows the order in which advertisements are not played in a loop. Here, it is assumed that the number of loops is one, and three advertisement content data (videos) are displayed. When playing in a loop, after advertisement A, advertisement B, and advertisement C are displayed, advertisement A, advertisement B, and advertisement C are displayed again. On the other hand, when playing in a loop, the advertisement video is not displayed after advertisement A, advertisement B, and advertisement C are displayed. In other words, when playing in a loop, the advertisement video is displayed for a longer time than when playing in a loop. It is said that the more times an advertisement is displayed, the more effective it is. On the other hand, if the advertisement display time is longer, the stay time in the toilet stall is longer and the toilet facility becomes crowded, which is undesirable because it reduces the convenience of the user. In particular, toilet facilities with multiple toilet stalls are often large buildings such as commercial buildings and office buildings, and are considered to be used by multiple users. Therefore, in this embodiment, in a toilet facility consisting of multiple toilet stalls, the advertisement video is displayed at a time according to the congestion situation. When the restroom facility is deemed not crowded (one or more restroom stalls are "vacant"), the advertisement video is displayed in a loop for a long time, and when the restroom facility is deemed crowded (all of the multiple restroom stalls in the restroom facility are "in use"), the advertisement is not played in a loop and the advertisement display is terminated in a short time.

Furthermore, in this embodiment, in the case of a toilet facility that originally has only one toilet cubicle installed, the congestion level of the toilet facility (number of cubicles in use/number of toilet cubicles) is either 1 or 0. A congestion level of 1 indicates that the toilet cubicle in which the display device 23 is installed is in use, and a congestion level of 0 indicates that the toilet cubicle in which the display device 23 is installed is vacant. In this case, the display device 23 cannot control the display of the advertisement video with a display time according to the congestion level, so the advertisement video is played in a loop without determining whether or not to loop the playback based on the congestion level.
Summary of the First Embodiment

As described above, in this embodiment, after a user enters a toilet stall, an advertisement video is displayed on the display device 23 installed in the toilet stall. At this time, the display device 23 is different between a toilet facility with multiple toilet stalls and a toilet facility with only one toilet stall. In a toilet facility with multiple toilet stalls, display control is performed so that the advertisement display time is based on the congestion state of the toilet facility, and in a toilet facility with only one toilet stall, display control is performed so that the advertisement display time is fixed regardless of the congestion state. Display control is performed with a fixed advertisement display time regardless of the congestion state. When display control is performed with an advertisement display time based on the congestion state, display control is performed so that the advertisement display time displayed when the toilet is crowded is shorter than the advertisement display time displayed when the toilet is not crowded. In this way, when it is desirable to prevent the user from staying in the toilet stall for a long time due to the display of the advertisement video, the advertisement display time is changed according to the congestion state, and in a facility where display control according to the congestion state is not necessary, the number of advertisements to be played can be secured without shortening the advertisement display time according to the congestion state. As described above, according to this embodiment, an advertisement video can be displayed in the toilet stall in a display form suitable for each toilet facility.

<Modification of the First Embodiment>
In this embodiment, whether or not to perform advertisement control according to the congestion state is determined depending on whether or not there is one toilet cubicle in the toilet facility. Alternatively, for example, a display mode for each building ID may be set in advance and switched. The first display mode is a mode in which advertisements are displayed for a display time according to the congestion state of the toilet cubicles in the toilet facility (occupancy rate of the cubicles and number of available cubicles), and the second display mode is a mode in which advertisement videos are displayed for a display time set in advance regardless of the congestion state. Furthermore, in the building information table 316, it is registered in advance whether the display mode is the first display mode or the second mode.
Furthermore, information indicating the display mode is also transmitted as display setting information to the display device 23, and the display device 23 can switch the display mode when displaying the advertisement. For example, when the determination unit 2342 determines in S807 whether to use the first display mode or the second display mode, the process proceeds to S808 when the first display mode is to be used, and when the second display mode is to be used, S808 is skipped and the process proceeds to S809. With this method as well, it is possible to achieve the same effect as the above-mentioned embodiment.

Alternatively, the display mode can be switched according to the type of building in which the restroom facility is located. In commercial buildings and office buildings, many restroom cubicles are installed in one restroom facility, assuming that many people will use the restroom cubicles. If a restroom cubicle is not available when you want to use it due to long-term stays in each cubicle, the convenience of the building is reduced. On the other hand, in convenience stores and small restaurants, it is not often assumed that many users will want to use the restroom cubicles at the same time, and users are also reluctant to stay for a long time because there is only one restroom cubicle, so there is a tendency for long-term stays to be less induced than in restroom facilities with many restroom cubicles.
Therefore, the display device 23 may be configured to pre-store whether to use the first display mode or the second display mode for each building genre, and the display device 23 may obtain information indicating the building genre corresponding to the display device 23 from the management server 10, and determine whether to use the first display mode or the second display mode based on the building genre.

In addition, information other than the number of cubicles in use/the number of cubicles in the restroom facility may be used as information indicating the degree of congestion. For example, the congestion degree derivation unit 313 may derive the number of cubicles whose usage information is in the "vacant" state as the degree of congestion. In this case, the display device 23 that has acquired the degree of congestion may loop playback of advertisements by determining in S808 whether the degree of congestion is 1 or greater.

In addition, in the above description, the advertising video is played in a loop, but it does not necessarily have to be played in a loop. For example, the display device 23 may display six pieces of advertising content data when it is OK to display a long advertising video (when it is not crowded or when display control according to congestion is not performed), and may display three pieces of advertising content data when the display time of the advertising video is shortened (when it is crowded).

In the above explanation, the display device 23 determines whether to display advertisements according to the congestion state or whether to display advertisements regardless of the congestion state, but the management server 10 may make the determination, for example.

[Second embodiment]
In the first embodiment, in the case of a toilet facility consisting of one toilet cubicle, one or more advertisement videos are played in a loop. However, even a toilet cubicle that is not usually crowded, such as a convenience store, may be crowded on days when there is a festival or event nearby. Therefore, in the second embodiment, a method for shortening the advertisement display time by specifying a specific date and time will be described. Note that detailed description of the same configuration as the first embodiment will be omitted, and different processing will be described.

The manager who operates the restroom facility can set the advertisement shortening date on the display device 23 using a management terminal (not shown) for managing the display device 23. The management terminal is, for example, a tablet terminal, a smartphone, or a PC (personal computer). The basic hardware resources of the management terminal have the same configuration as the display device 23 shown in FIG. 3(b), so a description is omitted. FIG. 10 is a registration screen for setting the advertisement shortening date displayed on the management terminal. In advance, the manager can set the date and time on which he wants to shorten the advertisement display time (the maximum playback time that can be displayed after the user enters and leaves the facility) in one use by the user. The information registered via the management screen shown in FIG. 10 is transmitted to the management server 10 and stored in the management server 10.

11 shows a flowchart of the advertisement display control process executed by the display device 23 in this embodiment. Each step can be realized by having the CPU 230 of the display device 23 load and execute a program capable of realizing the flowchart shown in FIG. 11. For example, after the display device 23 and the detection device 21 are installed in a toilet cubicle, the display device 23 is turned on, and the following flowchart is started. The processes from S801 to S813 are all the same as those in the first embodiment. Furthermore, in this embodiment, the determination unit 2342 determines in S1101 whether the current time is included in the time period specified for the advertisement shortening date. If the current time is included in the time period specified for the advertisement shortening date, the process proceeds to S812, where the display control unit 2343 does not execute loop playback and displays the initial screen. If the current time is included in the time period specified for the advertisement shortening date, the process proceeds to S807 and thereafter and continues.

According to this, the advertisement display time is shortened when any of the following conditions are met:
(A) The current time is included in the time period specified as the advertising shortening date.
(i) The toilet facility consists of multiple toilet cubicles and is crowded.
In addition, if (A) is not satisfied and either of the following two conditions is satisfied, the advertisement display time will be longer.
(c) The toilet facility consists of one toilet cubicle.
(e) The toilet facility consists of multiple toilet cubicles and is not crowded.
According to the present embodiment, in the system for displaying the advertising video on the display device 23 installed in the restroom stall, the days on which the display time is to be shortened can be set in advance. This makes it possible to prevent long-term stays due to long advertisement displays even in restroom stalls in restroom facilities with no other stalls by shortening the advertising video relatively regardless of the degree of congestion.

<Other embodiments>
In the above embodiment, the advertisement display time not depending on the congestion level is the same as the advertisement display time when the screen is not crowded. However, this is not essential. For example, the number of loops or the number of advertisement content data to be displayed may be different.
Although an example in which a fraction is used as the crowdedness degree has been described, it does not have to be a numerical value. For example, the crowdedness degree derivation unit 313 may output a text indicating the crowdedness degree according to the ratio of the number of used toilet cubicles to the total number of toilet cubicles included in the toilet facility. In this case, a text indicating the crowdedness degree, such as "vacant", "slightly crowded", or "full", may be transmitted to the display device 23, and the display device 23 may control the advertisement display time according to the previously set crowdedness status.

In the above embodiment, even for a toilet cubicle consisting of one cubicle, the congestion degree (number of cubicles in use/number of toilet cubicles included in the toilet facility) is obtained from the management server 10, but if advertisement display is not controlled according to the congestion degree, the display device 23 does not necessarily need to obtain the congestion degree from the management server. For example, as a modified example of the first embodiment described above, the advertisement display control process by setting the display mode is described, but in this case, the display mode may be determined before obtaining the congestion degree, and if it is the second display mode (display not based on the congestion degree), only the usage information corresponding to the display device 23 itself may be obtained. Furthermore, in this case, the processes of S807 and S808 may be skipped.
