[0010] The present embodiment will be described below with reference to the drawings. The same components will be denoted by the same reference numerals. Note that the following embodiment does not limit the technology of the present disclosure, and not all of the combinations of features described in the present embodiment are necessarily essential for solving the above-mentioned problems.

[0011] [First embodiment] In the first embodiment, a system is described in which a display device is installed in a toilet stall, and when it detects that a user has entered the toilet stall, the display device in the toilet stall displays content. Furthermore, in this embodiment, a method is described in which, if the user stays in the stall for a long period of time, an image including the user's stay time is displayed according to the congestion level of the toilet facility. Note that, hereinafter, a group of toilet stalls accessible via the same entrance / exit is considered to be one toilet facility.

[0012] <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 greater, and hereinafter, when referring collectively or individually, 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 stall and information on congestion in the toilet facility based on the results of user detection by the detection device 21 in each toilet stall. The management server 10 also has a content management function that stores video data of advertising content, information image data, image data for long-term stays, etc., and distributes them to the display device 23. The network 30 is a communication network including wired and wireless networks, such as the Internet, a public line network, and Wi-Fi (registered trademark).

[0013] FIG. 2 is a diagram showing examples 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). The detection device 21 may be, for example, 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 assumed 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 assumed that there is no user in the toilet cubicle 22. The detection result detected by the detection device 21, together with identification information of the detection device 21, is transmitted as detection information to the management server 10 via the network 30. In this embodiment, the detector 21 detects the open / closed state of the door every five seconds.

[0014] The display device 23 is an information processing device that displays videos or images, such as advertisements, while a user is using the restroom stall 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 restroom stall. The display device 23 is configured to be able to communicate with the management server 10, and can receive and store display data (content data) from the management server 10. The display data may be a still image, video, or text data, and may also be accompanied by audio output. The display device 23 also acquires information about the congestion status of the restroom facility (hereinafter referred to as "crowding information") and information about the presence or absence of a user in the corresponding restroom stall 22 (the stall in which the display device 23 is installed) (hereinafter referred to as usage information) from the management server 10, and displays the display data according to the congestion information and usage information.

[0015] <Example of hardware configuration of management server 10 and display terminal 23> 3(a) is a hardware configuration diagram of the management server 10. The management server 10 includes a CPU (Central Processing Unit) 110, a ROM (Read Only Memory) 120, a RAM (Random Access Memory) 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 RAM 130 hold data used by the CPU 110. The storage device 140 stores the program and database described below. The communication device 150 communicates with the detection device 21 and the display device 23 via the network 30.

[0016] FIG. 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 unit included in the display device 23. The ROM 231 and RAM 232 hold data used by the CPU 230. The storage device 233 stores programs and databases, which will be described later. 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.

[0017] <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, as software modules executed by the CPU 11 (functions configured by various programs loaded in the internal memory of the CPU 110), a receiving unit 311, an updating unit 312, a congestion degree derivation unit 313, an advertisement control unit 314, and a storage unit 315. For convenience of description below, these modules may be described as the operating entities, but because it is the CPU 110 that actually executes these modules, the CPU 110 may also be the operating entity.

[0018] The receiving unit 311 receives detection information from the detecting device 21 and accepts requests from the display device 23. The storage unit 315 has a building information table 316, a private room management table 317, and an advertisement table 318. FIG. 5 is a diagram showing examples of the configuration of the building information table 316, the private room management table 317, and the advertisement table 318. Each table can be configured, for example, by storing data describing the contents of records in the storage device 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 configured in any format as long as the respective data are linked.

[0019] The building information table 316 shown in FIG. 5(a) is a data table that manages information about the building in which each restroom facility is located. The building information table 316 includes, for example, a building ID (identification information that can identify the building), building name, building genre, address, business hours, and initial screen as constituent items. Here, business hours refer to the time period defined by the opening and closing times of the building in which the restroom facility is located, and is the time period during which the restroom facility can be used by users. The initial screen is a screen that is displayed when advertising content data is not being displayed, and in this embodiment, can be registered for each building. For example, an image displaying text such as "Thank you for using our facility in a clean environment" is used as the initial screen.

[0020] 5(b) is a data table for managing the usage status and congestion level of each toilet cubicle. For example, the cubicle management table 317 has the following configuration items: sensor ID, building ID, area ID, cubicle attribute, usage status, and congestion level. The sensor ID is identification information of the detection device 21 installed in the toilet stall. The building ID is identification information of the building in which the toilet facility is located. The stall attribute is information indicating attributes that limit users, such as the gender of users or whether the toilet is a 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 stall. An area ID is identification information for identifying restroom facilities, including restroom stalls. For example, if a building has restroom facilities on each floor, an area ID will be assigned to each restroom facility on each floor. In a three-floor building, if there are men's and women's restrooms on the north side of each floor and men's, women's, and multi-purpose restrooms on the south side of each floor, the building will have a total of 15 restroom facilities, and 15 different area IDs will be associated with and stored as identification information for the building ID of the building.

[0021] 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 toilet cubicle. Here, the state where there is no user is displayed as "vacant" and the state where there is a user is displayed as "in use" in text, but it is also possible to store the state as "0" when there is no user and "1" when there is a user. The congestion level is information indicating the degree of congestion of the restroom facility, including the restroom stalls. In this embodiment, the congestion level is a fraction with the number of remaining stalls "in use" in the restroom facility as the numerator and the number of restroom stalls included in the restroom facility as the denominator. The closer the congestion level is to 1, the more crowded it is. For example, the restroom facility with area ID "001" is a women's restroom consisting of two stalls, and one stall is "empty" and the other is "in use," so the number of remaining stalls (congestion level) for area ID "001" is 1 / 2. Therefore, the congestion level of the two restroom stalls with area ID "001" is stored as "1 / 2."

[0022] The advertisement table 318 is a data table that manages information about advertisements that can be displayed in the restroom display system. For each of a plurality of advertisements, the advertisement table 318 contains the following items: information identifying the advertisement (advertising ID), the advertiser providing the advertisement, the display period for the advertisement, a building ID that identifies the building where the advertisement will be displayed, and advertisement content data. In this embodiment, each advertisement is a 15-second video.

[0023] The update unit 312 updates the cubicle management table 317 based on the detection information received by the receiving unit 311 from the detection device 21. Since the detection information includes the identification information (sensor ID) 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 defined here as a fraction with the number of toilet cubicles "in use" (with users) as the numerator and the total 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.

[0024] The advertisement control unit 314 communicates with the display device 23 that displays the advertisements, and transmits data necessary for displaying the advertisements 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 restroom stall 22 during a time period designated for each restroom facility (preferably a period with 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, it is assumed that the advertisement control unit 314 distributes three advertisement content data as advertisement content data that can be displayed by the display device 23. Furthermore, when the receiving unit 311 receives a request from the display device 23, the advertisement control unit 314 transmits usage information and a congestion degree to the display device 23 as information necessary for the display device 23 to determine whether or not to display the advertisement.

[0025] 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 expanded in the internal memory of the CPU 230) executed by the CPU 230. For convenience of description, these modules may be described as the main operating units below, but since it is the CPU 230 that actually executes these modules, the CPU 230 may also be the main operating unit.

[0026] The acquisition unit 2340 acquires from the management server 10, information such as usage information and congestion level held by the management server 10, information about the terminal itself, and information about initial settings required for displaying the display device 23. The setting unit 2341 performs settings required for displaying on the display device 23. For example, the setting unit 2341 sets the initial screen and image data for long-term stays to be displayed during long-term stays. The determination unit 2342 determines whether the corresponding toilet cubicle 22 is in use based on the usage information acquired from the management server 10, and determines whether to display a long-term stay display image based on the stay time information and congestion level. In this embodiment, a first image and a second image are set as the long-term stay display image. Details of each image will be described later. Furthermore, even after the determination unit 2342 detects that the toilet cubicle is in use, it periodically acquires usage information and determines whether the usage information has been updated from "in use" to "vacant" in order to monitor whether the user has left the cubicle.

[0027] The display control unit 2343 controls the display on the display 236. In this embodiment, an initial screen (still image) is displayed while no user is in the toilet cubicle 22, and when a user enters the cubicle, advertising content data (moving image) is displayed. Furthermore, if the user's stay time is prolonged and the toilet facility is crowded, a display image for long stay is displayed. The counting unit 2344 counts the time spent by the user in the toilet cubicle 22 and outputs stay time information indicating the stay time. When the usage information acquired by the acquisition unit 2340 is updated from "vacant" to "in use", the counting unit 2344 starts counting the elapsed time. The counting unit 2344 stores the measured time as stay time information of the user. Furthermore, when the usage information acquired by the acquisition unit 2340 is updated from "in use" to "vacant", the counting unit 2344 resets the elapsed time.

[0028] <Sequence for managing toilet stall usage> Figure 6 shows a sequence diagram for managing the usage status of toilet stalls. Each process (step) is represented by "S." In S601, the detection device 21 installed in the toilet cubicle 22 detects whether the toilet cubicle is being used at predetermined time intervals (for example, 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. Here, it is assumed that the detection device 21 detects that the door is closed (which indicates that a user has entered the cubicle). In S602, the detection device 21 transmits the detection result indicating that the door is in the closed state and the identification information of the detection device 21 itself to the management server 10 as detection information.

[0029] In S603, the receiving unit 311 in the management server 10 receives the detection information from the detection device 21, and in S604, the updating unit 312 updates the private room management table 318 based on the received detection information. Specifically, the identification information included in the detection information is referenced, and the usage status of the corresponding private room in the private room management table 317 is updated to "in use." When the user of the toilet stall leaves the stall, in S605 the detection device 21 detects that the door is open, and in S606 the detection device 21 transmits the detection result indicating that the door is open and the identification information of the detection device 21 itself as detection information to the management server 10. In this embodiment, since the detection device 21 detects the open / closed state of the door every 5 seconds, the detection device 21 continues to transmit the detection result indicating that the door is closed to the management server 10 even after S602, but this is omitted for simplicity of explanation.

[0030] In S607, the receiving unit 311 in the management server 10 receives the detection information, and in S608, the updating unit 312 updates the private room management table 318 based on the received detection information. Here, the usage status of the corresponding private room in the private room management table 317 is updated to "vacant." In this embodiment, the detection device 21 transmits detection information to the management server 10 every 5 seconds, but in addition to transmitting data periodically every 5 seconds, the detection device 21 may also transmit to the management server 10 that the door is closed when it detects that the door is closed.

[0031] <Congestion Degree Calculation Process> The congestion level derivation process executed by the congestion level derivation unit 313 in the management server 10 will be described in detail below. Fig. 7 shows a flowchart of the congestion level derivation process. The CPU 110 of the management server 10 can implement each step by reading and executing a program capable of implementing the flowchart shown in Fig. 7. First, in S701, the congestion degree derivation unit 313 determines the 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 ID 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 unit 313 identifies the toilet cubicles 22 of the area ID to be processed, and acquires the usage information of each toilet cubicle.

[0032] In S702, the congestion degree derivation unit 313 counts the number of toilet cubicles in the area ID to be processed and sets this as the number of toilet cubicles. Furthermore, among the toilet cubicles in the area ID to be processed, the number of toilet cubicles whose usage information is "in use" is counted and set this as the number of remaining cubicles. The congestion degree derivation unit 313 determines the congestion degree corresponding to the area ID as a fraction with the number of remaining cubicles as the numerator and the number of toilet cubicles as the denominator.

[0033] 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 level derivation unit 313 determines whether there is an area ID to be processed next. If there is an unprocessed area ID (YES), the process returns to S701. If there is no unprocessed area ID (NO), the process ends. In this embodiment, since registered area IDs are processed, the congestion level derivation unit 313 determines in S705 that there is an unprocessed area ID as long as a data set corresponding to the area ID is in the private room management table 317. For example, if two area IDs are registered, congestion levels are derived alternately for the two area IDs. Here, if the management server 10 is unable to access the private room management table 317, or if an instruction to end the congestion level derivation process is received from an external operation via the communication device 150 or the CPU 110, the determination in S705 is NO. With the above, the congestion degree derivation process in the management server 10 is completed.

[0034] <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 having the CPU 230 of the display device 23 load and execute a program capable of realizing the flowchart shown in Fig. 8. For example, the display device 23 starts the following flowchart at a pre-specified time, such as when the restroom facility in which the display device 23 is installed starts operating. 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) along with the identification information (tablet ID) of the display device 23 itself, and acquires the display setting information. In this embodiment, the display setting information acquired includes information indicating business hours corresponding to the area ID, attributes, and building ID corresponding to the identification information of the display device 23 itself, image data used as an initial screen, and image data for long-term stays.

[0035] In S802, the setting unit 2341 performs settings related to the 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 first image data for long-term stay and second image data for long-term stay to be displayed when the user is staying for a long period of time. The setting unit 2341 also sets a first predetermined time and a second predetermined time for determining whether the user is staying for a long period of time. In this embodiment, the first predetermined time is set to 10 minutes, and the second predetermined time is set to 20 minutes. In S803, the display control unit 2343 causes the display 236 to display the image data set as the initial screen.

[0036] In S804, the acquisition unit 2340 acquires the congestion degree and usage information (information indicating whether the terminal is in use or vacant) corresponding to the terminal from the management server 10. The congestion degree acquired here indicates the congestion state of the toilet facility including the toilet cubicle 22 in which the terminal is installed. 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 counting unit 2344 starts counting and the process proceeds to S806 and S812, and if it is "vacant", the process proceeds to S811.

[0037] The processes from S806 to S809 are executed on the assumption that the user remains in the restroom stall. In S806, the display control unit 2343 displays N pieces of advertising content data that have been distributed in advance on the display 236. In this embodiment, three pieces of advertising 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 advertising content data in random order. Note that, here, it is assumed that the three content data are repeatedly played back in the order in which they were initially played back until the display control unit 2343 switches to another image (or video).

[0038] In S807, the counting unit 2344 refers to the information on the user's stay time from the time of entry, and when it detects that the first predetermined time has elapsed, the process proceeds to S808. In S808, the determination unit 2342 further refers to the crowdedness level to determine whether the toilet facility including the toilet cubicle 22 corresponding to its own terminal is crowded. In this embodiment, the determination unit 2342 determines whether the fraction indicating the crowdedness level is 1 or not. In other words, the determination unit 2342 determines the crowded state based on whether the toilet facility is full (all toilet cubicles in the toilet facility are in use). If the determination unit 2342 determines that the toilet facility is not crowded (not full), it proceeds to S810, and if it determines that the toilet facility is crowded (full), it proceeds to S809.

[0039] In S809, the display control unit 2343 generates a first image including the stay time based on the congestion level and stay time information, and displays the first image on the display 236. FIG. 9(a) is a diagram showing an example of the first image. The first image displays the availability of the restroom facility and the user's stay time. This image is intended to encourage long-staying users to promptly use the restroom stall, in order to prevent a situation where a user stays unnecessarily for an extended period of time when the restroom facility is crowded, thereby preventing other users from using the restroom stall. When the stay time exceeds a first predetermined time, the advertisement display on the display 236 is switched to the first image. The display control unit 2343 generates the first image by inserting text data indicating the congestion level and text data indicating the stay time into an image generated using the first long-term stay image data. In this case, since the congestion level is 1, text data indicating "full" is displayed.

[0040] Next, in S810, the counting unit 2344 references the stay time information from the time the user entered the toilet and detects the passage of a second predetermined time. If the counting unit 2344 detects that the stay time has exceeded the second predetermined time, the process proceeds to S811. In S811, the display control unit 2343 generates a second image including the stay time based on the stay time information on the image generated using the second long-term stay image data, and displays the second image on the display 236. FIG. 9(b) is a diagram showing an example of the second image. The second image displays the stay time as well as a button area for calling an attendant. This allows the user to call an attendant because a person who continues to use the toilet stall for a long time after the first image is displayed may be unable to leave due to some reason, such as illness. If the user taps the button labeled "Call an Attendant," the display device 23 sends an email or a notification to a pre-set contact or a pre-registered information processing device that the user has called, along with information that identifies the toilet stall 22. When the second image is displayed for a certain period of time (for example, one hour), the second image continues to be displayed on the display 236 of the display device 23 until it is detected that the user has left the room.

[0041] In parallel with the processing from S806 to S809, in S814 the determination unit 2342 monitors the exit of a user who is using the toilet cubicle 22. Specifically, the determination unit 2342 sends a request for usage information to the management server 10 at predetermined time intervals (for example, every 5 seconds), continuously 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.

[0042] 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 S814 to S812, other content, such as an advertisement or the first image, is forcibly terminated even if it is currently being displayed, 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, because S810 is displayed after the display device 23 displays an advertisement to the user, a still image containing text such as "Thank you for using our service" or "Please be careful not to leave anything behind" may be used. However, it is desirable that the image displayed in S810 be a still image rather than a moving image that includes changes, in order to prevent users from staying longer.

[0043] In S812, the determination unit 2342 determines whether to complete the process. Specifically, the determination unit 2342 determines whether the current time 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, the process is deemed not to end and the process returns to S804. If the current time is outside the business hours, the process is determined to end and the process is completed. This completes the advertisement display control process in the display device 23.

[0044] <Flow of advertising in toilet stalls> FIG. 10 is a diagram for explaining the flow of advertisements that are displayed. The horizontal axis schematically indicates the passage of time, and the displayed content is shown in order. Note that the content shown is that which occurs after the user enters the room and the initial screen is updated to an advertisement, and the display of the initial screen is omitted. FIG. 10(a) shows a case where the user's stay time is less than the first predetermined time, and only an advertisement is played after the initial image. The advertisement is displayed on the display device 23 until it is detected that the user has left the room.

[0045] Here, if the advertisement display time is prolonged, the user's stay in the restroom stall may increase, causing the restroom facility to become crowded, which is undesirable and reduces convenience for other users. Therefore, as shown in FIG. 10(b), if the restroom facility, including the restroom stall used by the user, is crowded when the user's stay time exceeds a first predetermined time, the advertisement displayed on the display device 23 is terminated and switched to a first image including the user's stay time. By terminating the advertisement display, the user's tendency to stay longer due to viewing the advertisement is suppressed, and by informing the user of the congestion status and the length of stay, the user can be encouraged to leave. On the other hand, if the user's stay time exceeds the first predetermined time but the restroom facility is not crowded, the advertisement continues to be displayed until the user's departure is detected. If there are other available stalls in the restroom facility, the user's long stay does not pose a significant disadvantage to other users or the restroom facility operator, so the advertisement continues to be displayed without a message encouraging the user to leave.

[0046] Furthermore, if the stay time exceeds a second predetermined time that is longer than the first predetermined time, a second image including the stay time is displayed regardless of the congestion status of the restroom facility. The second image displays the stay time, text confirming the user's safety, and a button to call an attendant. The second image is intended to encourage users to leave the restroom regardless of congestion if they are staying for an unnecessarily long period of time, while also confirming the user's safety in consideration of the possibility that they may be unable to leave the restroom stall for some reason.

[0047] <Summary of the First Embodiment> As described above, in this embodiment, after a user enters a restroom stall, an advertising video is displayed on the display device 23 installed in the restroom stall. If the user continues to stay in the restroom stall for up to a first predetermined time, the advertising video is either displayed as is or switched to an image including the length of stay, depending on the congestion level of the restroom facility. If the user continues to stay in the restroom stall and the length of stay exceeds a second predetermined time, the display of the advertising video ends and an image including the length of stay is displayed, regardless of the congestion level of the restroom facility. In other words, the timing at which the length of stay is displayed is controlled depending on the congestion level of the restroom facility. When the restroom is crowded, the length of stay is displayed on the display device 23 in the restroom stall earlier than when it is not crowded. As a result, if it is desirable to prevent users from staying in restroom stalls for a long period of time due to the display of advertising videos, the advertisement display time is varied according to the congestion level, and the length of stay is displayed according to the congestion level. When the restroom facility is crowded, the advertisement display is stopped early and the length of stay is displayed to encourage users to use the facility quickly, and when the restroom facility is not crowded, the advertisement is displayed for a longer period of time than when the restroom facility is crowded, and then an image including the length of stay is displayed. As described above, according to this embodiment, by controlling the timing of displaying the length of stay on the display device 23 according to the congestion level of the restroom facility, it is possible to encourage users to leave appropriately.

[0048] [Second embodiment] In the first embodiment, a method was described in which an image including the length of stay to encourage a user to leave the toilet is displayed on the display device 23 in the toilet stall 22 according to the congestion level and stay time information. In the second embodiment, a method is described in which an image including the length of stay is displayed regardless of the congestion level in a case where there is only one toilet stall, such as in a convenience store. Note that detailed explanations of the same configuration as in the first embodiment will be omitted, and only different processing will be explained.

[0049] FIG. 11 shows a flowchart of advertisement display control processing in the second 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. This embodiment differs from the first embodiment in that the processing of S815 is added. In S815, the determination unit 2342 determines whether or not to execute display processing according to the congestion level. In this embodiment, the determination unit 2342 determines whether or not there is a total number of toilet cubicles. Specifically, since the denominator of the congestion level acquired in S804 indicates the total number of toilet cubicles, the determination unit 2342 determines whether or not to execute display according to the congestion level based on whether or not the denominator of the congestion level is 2 or greater. Here, if the number of toilet cubicles is 2 or greater (i.e., there are multiple toilet cubicles in the toilet facility), the process proceeds to S807, where display control is performed according to the congestion status and stay time information, as in the first embodiment. On the other hand, if the number of toilet cubicles is 1 (i.e., there are no other toilet cubicles in the toilet facility), the process proceeds to S809.

[0050] As described above, according to the second embodiment, if a restroom facility has multiple restroom cubicles, and a user stays in the restroom cubicle for a long period of time, advertisement display is stopped based on the congestion situation and stay time information, and an image including the stay time is displayed. If a restroom facility has only one restroom cubicle, and a user stays in the restroom cubicle for a long period of time, advertisement display is stopped based only on the stay time, and an image including the stay time is displayed. According to the present embodiment, in a system for displaying advertising videos on a display device 23 installed in a toilet stall, in toilet facilities where it is not possible to derive the congestion status based on the usage status of other toilet stalls, an image including the length of stay based only on the stay time information can be displayed, thereby preventing long stays due to long advertisement displays.

[0051] In addition to the method of determining whether to refer to the congestion status based on the number of restroom cubicles, for example, in an office building that is also used as an office and where long-term stays are not desired regardless of the congestion status, the determination unit 2342 may make a determination in S815 based on the type of building in which the restroom facility is installed (commercial building, office building, etc.). In this case, if the restroom facility is an office building, the determination unit 2342 proceeds to S811 without performing the process of S808, and if the restroom facility is a commercial facility, the determination unit 2342 proceeds to S807.

[0052] [Third embodiment] In the first and second embodiments, the timing at which an image including the length of stay (first image or second image) can be displayed is only when a first predetermined time or a second predetermined time has elapsed after entry is detected. In the third embodiment, a system will be described in which the congestion degree is periodically acquired after the first predetermined time has elapsed, and an image including the length of stay (here, the first image) will be displayed when the restroom facility becomes crowded between the first predetermined time and the second predetermined time. Note that the same components as in the first embodiment will be described using the same reference numerals, and detailed processing will be omitted.

[0053] Fig. 12 shows a flowchart of the advertisement display control process in the second 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. The process different from the flowchart shown in Fig. 8 in the first embodiment will be described. First, instead of S804, in S1201 the acquisition unit 2340 acquires usage information corresponding to its own terminal from the management server 10. When entry of a user into the room is detected based on the usage information in S805, in S1202 the acquisition unit 2340 acquires the congestion degree corresponding to its own terminal from the management server 10. When returning to S1202 from A1203 or S1204 (described later), S1202 is re-executed after a predetermined interval (for example, 10 seconds) has elapsed since the previous execution of S1202.

[0054] In S1203, the determination unit 2342 determines whether the stay time counted by the counting unit 2344 is equal to or greater than a first predetermined time. If the stay time is equal to or greater than the first predetermined time, the process proceeds to S1204. If the stay time is less than the first predetermined time, the process returns to S1202. If the stay time is equal to or greater than the first predetermined time, the process proceeds to S1204, where the determination unit 2342 determines whether the restroom facility is crowded based on the congestion level. If the restroom facility is crowded, the process proceeds to S809. If the restroom facility is not crowded, the process returns to S1202. The processing from S809 onwards is the same as in the first embodiment.

[0055] In this embodiment, an image including the stay time is displayed at the following timings. (A) When the stay time is between the first predetermined time and the second predetermined time and it is detected that the restroom facility is crowded. (a) When it is detected that the stay time has exceeded a second predetermined time. In this embodiment, the congestion degree is obtained periodically between the first and second specified times, and if the restroom facility becomes crowded during the stay, a display image for long-term stays will be displayed to encourage users to leave quickly.

[0056] <Other embodiments> In the above-described embodiment, the first and second predetermined times are fixed, but they may be registered in advance for each toilet facility or each building in which the toilet facility is installed. In this case, the first and second predetermined times corresponding to the pre-registered toilet cubicles 22 are read and set before the process of S807 in the flowchart shown in FIG. 8 is executed. For example, the first and second predetermined times may be set relatively short in toilet facilities that tend to be crowded, and the first and second predetermined times may be set longer in toilet facilities that are not often crowded. Alternatively, the interval between the first and second predetermined times may be different depending on the toilet facility.

[0057] In the above-described embodiment, when a user enters a toilet cubicle, an advertising video is displayed on the display device 23. However, the display control unit 2343 may be configured to display only the initial image and not any image including content other than advertisements or the length of stay. Furthermore, when the length of stay is equal to or longer than a first predetermined time but shorter than a second predetermined time, and the toilet facility is not crowded, the display control unit 2343 may select and display an advertisement with content related to long-term use of the toilet cubicle. It may be assumed that users who use toilet cubicles for long periods of time tend to have attributes that make them prone to stomach pain, and therefore advertising videos for, for example, intestinal regulators or laxatives may be preferentially delivered.

[0058] In the above embodiment, when the restroom facility is crowded, the first image and the second image are displayed if the user has been staying there for a second predetermined time or longer. However, a common image may be displayed. In this case, for example, the display control unit 2343 displays the first image if the user's stay exceeds the first predetermined time and the restroom facility is crowded, and displays the content (such as an advertisement) that was displayed after the user entered the restroom if the user's stay exceeds the second predetermined time. Furthermore, if the user's stay exceeds the second predetermined time, the first image is displayed regardless of the congestion status of the restroom facility. In other words, if the restroom facility is crowded, the first image continues to be displayed. Furthermore, while the image data for long-term stays is fixed data regardless of the building or restroom facility, it may be possible to set it for each building or restroom facility, as with the initial screen.

[0059] Furthermore, information other than the number of occupied cubicles / 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 "vacant" as the degree of congestion. In this case, the display device 23, having acquired the degree of congestion, may determine whether to stop displaying advertisements by determining whether the degree of congestion is 0 in S808. Alternatively, the degree of congestion does not have to be a numerical value. For example, the congestion degree derivation unit 313 may output text indicating the degree of congestion based on the ratio of the number of occupied cubicles to the total number of cubicles included in the restroom facility. In this case, text indicating the degree of congestion, 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 based on a preset status of the degree of congestion. Furthermore, in the first embodiment, the determination unit 2342 determines whether the degree of congestion is 1 (whether the cubicles are full or not), but this is not limiting. For example, the determination unit 2342 may determine that the restroom facility is crowded when 80% of the stalls are in use, such as 0.8, in terms of a fraction indicating the degree of congestion of the restroom facility.

[0060] In the above embodiment, the advertising video is looped after the user enters the room until the advertising display is stopped, but the loop playback is not necessarily required. For example, if it is acceptable to display a long advertising video, the display device 23 may increase the amount of advertising content data to be displayed or randomly select and display advertising content data.

[0061] Furthermore, in the above-described embodiment, if the counting unit 2344 in the display device 23 counts the usage time (stay time) of the user, the management server 10 may also be configured to have the function of the counting unit 2344. In this case, the acquiring unit 2340 of the display device 23 periodically (at predetermined intervals) acquires information indicating the stay time in the corresponding toilet cubicle 22 from the management server 10 while the content is being displayed on the display 236. Furthermore, in the above-described embodiment, the acquisition unit 2340 acquires the congestion degree in S804, but in order to refer to the congestion situation in more real time, the congestion degree may be acquired from the management server 10 at predetermined time intervals or immediately before executing the processing of S808.
