(Embodiment)
[composition]
The configuration of a display system according to an embodiment will be described below: Fig. 1 is a block diagram showing the functional configuration of a display system according to an embodiment.

The display system 10 shown in Figure 1 is a system that can display content provided from the distribution system 20 on the display unit 71 of the display device 70 and the display unit 54a of the intercom master unit 54. The display device 70 is a device installed in the common area (entrance) of the apartment complex 100, and has a relatively large display unit 71. Figure 2 is an external view of the display device 70. The intercom master unit 54 is a device installed in the private area of the apartment complex 100, and has a relatively small display unit 54a. The apartment complex 100 is an example of a collective facility, and more specifically, is an apartment building, dormitory, company housing, etc. The private area within the apartment complex 100 is an example of a facility included in a collective facility.

Specifically, the display system 10 comprises a distribution system 20, a gateway device 30, a hub device 40, an intercom system 50, a display control device 60, and a display device 70. The distribution system 20 is a system installed outside the apartment complex 100, while the gateway device 30, hub device 40, intercom system 50, display control device 60, and display device 70 are installed within the premises of the apartment complex 100.

The distribution system 20 is a system that distributes content information and is realized, for example, by one or more server devices (cloud servers). The content information distributed by the distribution system 20 includes first content information for the intercom system 50, which is displayed on the display unit 54a of the intercom master unit 54, and second content information for the display control device 60, which is displayed on the display unit 71 of the display device 70.

The first content information and the second content information are, for example, advertising information provided by various businesses. The first content information and the second content information also include information provided by local governments. There is no clear distinction between the first content information and the second content information, and some content information may be used as both the first content information and the second content information. Specifically, the distribution system 20 includes a first distribution unit 21, a second distribution unit 22, an information processing unit 23, and a memory unit 24.

The first distribution unit 21 is a communication circuit (communication module) that distributes first content information intended for the intercom system 50. The first distribution unit 21 communicates with the gateway device 30 via a wide-area communication network such as the Internet. The communication performed by the first distribution unit 21 is, for example, wired communication, but may also be wireless communication. There are no particular limitations on the communication standard used for the communication performed by the first distribution unit 21.

The second distribution unit 22 is a communication circuit (communication module) that distributes second content information intended for the display control device 60. The second distribution unit 22 communicates with the gateway device 30 via a wide area communication network. The communication performed by the second distribution unit 22 is, for example, wired communication, but may also be wireless communication. There are no particular limitations on the communication standard used for communication performed by the second distribution unit 22.

Note that in Figure 1, the first distribution unit 21 and the second distribution unit 22 are depicted separately from a functional perspective, but the first distribution unit 21 and the second distribution unit 22 may be a single communication circuit (communication module).

The information processing unit 23 distributes content information using the first distribution unit 21 and the second distribution unit 22. The information processing unit 23 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the information processing unit 23 are realized, for example, by the microcomputer or processor that constitutes the information processing unit 23 executing a computer program stored in the storage unit 24.

The storage unit 24 is a storage device that stores various content information and computer programs executed by the information processing unit 23 to distribute content information. The storage unit 24 is realized, for example, by semiconductor memory.

The gateway device 30 is a communication device that enables devices or systems installed in the apartment building 100, such as the intercom system 50 and the display control device 60, to communicate with the distribution system 20. The gateway device 30 comprises a first gateway communication unit 31, a second gateway communication unit 32, an information processing unit 33, and a memory unit 34. Note that in FIG. 1, the first gateway communication unit 31 is referred to as the first GW communication unit 31, and the second gateway communication unit 32 is referred to as the second GW communication unit 32.

The first gateway communication unit 31 is a communication circuit (communication module) that communicates with the distribution system 20 (a system outside the apartment complex 100). The first gateway communication unit 31 communicates with the distribution system 20 via a wide-area communication network such as the Internet. The communication performed by the first gateway communication unit 31 is, for example, wired communication, but may also be wireless communication. There are no particular limitations on the communication standard used for communication performed by the first gateway communication unit 31. Specifically, the first gateway communication unit 31 receives content information from the distribution system 20.

The second gateway communication unit 32 is a communication circuit (communication module) that communicates with the intercom system 50 and the display control device 60. The second gateway communication unit 32 communicates with the intercom system 50 and the display control device 60 via a local communication network. The communication performed by the second gateway communication unit 32 is, for example, wired communication, but may also be wireless communication. There are no particular limitations on the communication standard used for communication performed by the second gateway communication unit 32.

Specifically, the second gateway communication unit 32 transmits, from the content information received by the first gateway communication unit 31, first content information intended for the intercom system 50 to the intercom system 50 via a first route. The second gateway communication unit 32 transmits, from the content information received by the first gateway communication unit 31, second content information intended for the display control device 60 to the display control device 60 via a second route different from the first route. Note that the first route includes a communication route from the second gateway communication unit 32 to the intercom master unit 54 via the control device 51 of the intercom system 50.

The information processing unit 33 transmits the content information received by the first gateway communication unit 31 to the intercom system 50 or the display control device 60 using the second gateway communication unit 32. The information processing unit 33 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the information processing unit 33 are realized, for example, by the microcomputer or processor that constitutes the information processing unit 33 executing a computer program stored in the memory unit 34.

The memory unit 34 is a storage device that stores content information received by the first gateway communication unit, computer programs executed by the information processing unit 33 to transmit content information, and the like. The memory unit 34 is realized, for example, by semiconductor memory.

The hub device 40 is a network device that forms the first and second routes (branches the communication routes) in the apartment complex 100. Note that if the gateway device 30 has the functionality of the hub device 40, the hub device 40 can be omitted.

The intercom system 50 is a system for communicating audio and video between a lobby intercom 52 and multiple intercom master units 54 installed in private areas within the apartment complex 100. The intercom system 50 includes a control device 51, a lobby intercom 52, an auto-locking door 53, and multiple intercom master units 54.

The control device 51 controls communications between the lobby intercom 52 and each of the multiple intercom master units 54 (calls between visitors to the apartment complex 100 and residents of the private areas). The control device 51 also transmits the first content information received from the gateway device 30 to at least some of the multiple intercom master units 54.

The lobby intercom 52 is a device located in the common area (entrance) of the apartment complex 100, outside (on the outdoor side) of the auto-locking door 53. The lobby intercom 52 is equipped with, for example, an authentication unit 52a that performs authentication processing, and unlocks or opens the auto-locking door 53 when authentication by the authentication unit 52a is successful. The authentication unit 52a is a device that performs biometric authentication such as facial recognition, or IC card authentication, and is realized by a microcomputer (processor), memory, etc.

The auto-locking door 53 is a door provided in the common area (entrance) of the apartment complex 100, in other words, it is the door for entering and exiting the apartment complex 100. The auto-locking door 53 automatically locks (or closes) a certain period of time after it is unlocked or opened. The door that the auto-locking door 53 has may be a sliding door or a hinged door.

The intercom master unit 54 is an information terminal fixedly installed in the private area of the apartment complex 100. For example, an intercom master unit 54 is provided in each of the multiple private areas. The intercom master unit 54 performs information processing that enables residents of the private areas to communicate with visitors via the lobby intercom 52 or an intercom handset (not shown). The intercom handset is a so-called door phone and is provided outside the entrance to the private area.

The intercom master unit 54 is equipped with a display unit 54a. The display unit 54a displays an image of a visitor standing in front of the lobby intercom 52 or intercom slave unit. The intercom master unit 54 also receives first content information from the control device 51 and displays (visualizes) the first content information on the display unit 54a. The display unit 54a is implemented by a display panel such as a liquid crystal panel or an organic EL (Electro-Luminescence) panel.

The display control device 60 is a device that receives second content information from the gateway device 30 and displays (visualizes) the received second content information on the display unit 71 of the display device 70. The display control device 60 may be a device separate from the display device 70, or may be a device integrated with the display device 70. The display control device 60 includes a first communication unit 61, a second communication unit 62, a control unit 63, a memory unit 64, an acquisition unit 65, and an operation reception unit 66.

The first communication unit 61 is a communication circuit (communication module) that communicates with the intercom system 50. The first communication unit 61 communicates with the intercom system 50 via a local communication network. The communication performed by the first communication unit 61 is, for example, wired communication, but may also be wireless communication. There are no particular limitations on the communication standard used for communication performed by the first communication unit 61. Specifically, the first communication unit 61 receives intercom information from the intercom system 50.

The second communication unit 62 is a communication circuit (communication module) that communicates with the gateway device 30. The second communication unit 62 communicates with the gateway device 30 via a local communication network. The communication performed by the second communication unit 62 is, for example, wired communication, but may also be wireless communication. There are no particular limitations on the communication standard used for communication performed by the second communication unit 62. Specifically, the second communication unit 62 receives second content information from the gateway device 30.

Note that in Figure 1, the first communication unit 61 and the second communication unit 62 are distinguished from a functional standpoint, but the first communication unit 61 and the second communication unit 62 may be a single communication circuit (communication module).

The control unit 63 displays an image on the display unit 71 of the display device 70 based on at least one of the intercom information received by the first communication unit 61 and the second content information received by the second communication unit 62. The control unit 63 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the control unit 63 are realized, for example, by the microcomputer or processor constituting the control unit 63 executing a computer program stored in the memory unit 64.

The storage unit 64 is a storage device that stores the second content information and the computer program executed by the control unit 63 to display the second content information. The storage unit 64 is realized, for example, by a semiconductor memory.

The acquisition unit 65 is a sensor that acquires information about people positioned around the display device 70 (for example, information indicating the presence or absence of people). The acquisition unit 65 is, for example, a human presence sensor that senses the presence or absence of people positioned around the display device 70 based on infrared rays emitted from the person's body. The acquisition unit 65 may be a human presence sensor that senses the presence or absence of people based on the reflection intensity of infrared rays when they are emitted. The acquisition unit 65 may also be an image sensor (camera) that senses the presence or absence of people positioned around the display device 70 from images. Note that the acquisition unit 65 may be separate from the display control device 60. For example, the acquisition unit 65 may be located away from the display control device 60 so that it is easier to detect people.

The operation reception unit 66 is a sensor that receives operations from a person viewing the display unit 71 of the display device 70. Operation here includes both manual operation and voice operation. The operation reception unit 66 may be, for example, a contact-type sensor such as a touchscreen overlaid on the display unit 71, but may also be a non-contact sensor such as a gesture sensor or a microphone (sound sensor).

Display device 70 is located in the common area (entrance) of apartment complex 100, inside (indoor side) of auto-lock door 53, and displays (presents) images to people passing in front of display device 70. As shown in FIG. 2, display device 70 has a relatively large display unit 71, similar to a digital signage device. Display unit 71 is realized by a display panel such as a liquid crystal panel or an organic EL panel.

Note that the display device 70 may be realized by a projector and a screen. In other words, displaying an image on the display device 70 includes the projector projecting the image onto the screen.

[Display example of first content information on intercom master unit]
Distribution system 20 distributes first content information to intercom system 50 installed in apartment building 100 via a first route, and the first content information is displayed on display unit 54a of intercom master unit 54. An example of how the first content information is displayed on display unit 54a of intercom master unit 54 will be described below. Figure 3 is a diagram showing an example of how the first content information is displayed on display unit 54a of intercom master unit 54.

As shown in Figure 3(a), the display unit 54a displays a list of summaries (text) of multiple pieces of first content information. In this state, when a resident or other person selects one piece of first content information, a details screen of the selected first content information is displayed on the display unit 54a, as shown in Figure 3(b).

The first content information may be, for example, information about stores near the apartment complex 100 (specifically, sale information about products sold at the stores, etc.), or in other words, advertising information. As shown in FIG. 3(b), the display unit 54a may display a two-dimensional code for downloading coupons that can be used at the stores to a mobile terminal. The first content information may also be information about the condominium management company, condominium association, etc.

The first content information may also include information to be notified by push notification. For example, when there is first content information to be notified by push notification, a light-emitting unit (e.g., an indicator realized by a light-emitting element such as an LED) provided on the intercom master unit 54 may flash, and when a resident or other user operates it, a detailed screen of the first content information may be displayed.

[Display example of second content information (image) on display device]
The distribution system 20 distributes the second content information to the display control device 60 via the second route, and the control unit 63 of the display control device 60 can display the second content information received by the second communication unit 62 on the display unit 71 of the display device 70. An example of how the second content information is displayed on the display unit 71 of the display device 70 will be described below. Figure 4 is a diagram showing an example of how the second content information is displayed on the display unit 71 of the display device 70.

As shown in (a) of FIG. 4, the display unit 71 displays a list of multiple pieces of second content information (thumbnails showing an overview of the second content information). Note that the second content information that is displayed preferentially is displayed in a larger size than the other pieces of second content information. The priority order (priority) for displaying the second content information will be described later. Note that the display unit 71 is in a sleep state (a state in which a black screen is displayed) when there is no one nearby, and when the acquisition unit 65 acquires information indicating that there is a person nearby, the image shown in (a) of FIG. 4 is displayed on the display unit 71.

In this state, when the operation acceptance unit 66 accepts an operation by a resident or the like to select one of the multiple pieces of second content information, the control unit 63 displays a details screen of the selected second content information on the display unit 71, as shown in FIG. 4(b). In this way, the second content information includes information that is displayed as a list or in detail, and the control unit 63 can display detailed information (details screen) about the second content information on the display unit 71 (display device 70) based on an operation on the operation acceptance unit 66.

The second content information is, for example, information about stores near the apartment complex 100 (specifically, sale information about products sold at the stores, etc.), or in other words, advertising information. In this respect, it is similar to the first content information. The second content information may also include information from local governments, weather information, public transportation information, etc. Weather information and public transportation information may be displayed, for example, when information indicating that someone is about to leave the apartment complex 100 is acquired by the acquisition unit 65 (in this case, a camera, etc.).

[Example of distribution of first content information and second content information]
Incidentally, since the first route used for distributing the first content information is also used for communication between the lobby intercom 52 and the intercom master unit 54, it is desirable that the first content information be distributed in a manner that does not interfere with communication between the lobby intercom 52 and the intercom master unit 54. Furthermore, if the first content information is distributed to the intercom master unit 54 frequently, residents and the like may find it annoying.

Therefore, the first content information may be limited in at least one of the length of the period during which distribution is permitted, the distribution frequency, and the number of distributions (per a predetermined period such as one day). Specifically, the first content information may be limited in the length of the period during which distribution is permitted, the distribution frequency, or the number of distributions (per a predetermined period such as one day) than the second content information.

This allows the display system 10 to prevent communication between the lobby intercom 52 and the intercom master unit 54 from being interrupted and to prevent residents and others from feeling annoyed. In this way, the first content information and the second content information can be said to differ in at least one of the distribution timing, distribution frequency, and number of distributions.

[Example of image display based on intercom information on a display device]
The control unit 63 of the display control device 60 can display an image on the display unit 71 of the display device 70 based on the intercom information received by the first communication unit 61. An example of an image displayed on the display unit 71 of the display device 70 will be described below.

For example, a visitor to the apartment complex 100 (who may be a resident or a non-resident) authenticates himself/herself at the lobby intercom 52, unlocks or opens the auto-lock door 53, and then passes through the entrance (around the display device 70) (see Figure 2). At this time, the identification information of the visitor who has been successfully authenticated is registered in advance, so the lobby intercom 52 can transmit the identification information (e.g., name) of the visitor who has been successfully authenticated to the display control device 60 as intercom information. Note that the identification information may include attribute information (such as gender and age group) in addition to personal identification information such as the visitor's name or identification number. The identification information may include at least one of personal identification information and attribute information.

When intercom information including identification information is received by the first communication unit 61 of the display control device 60, the control unit 63 can display an image such as that shown in Figure 5A based on the received intercom information (identification information). Figure 5A is a diagram showing a first display example of an image based on intercom information on the display unit 71 of the display device 70.

The visitor's name is included at the top of the image shown in Figure 5A, and it can be said that the control unit 63 displays at least a portion of the image based on the identification information.

Furthermore, if the intercom system 50 manages the usage status of delivery lockers, the lobby intercom 52 can transmit inventory information to the display control device 60 as intercom information indicating that a package addressed to a visitor who has been successfully authenticated has been placed in the delivery locker. The inventory information is an example of information related to the equipment systems installed in the apartment complex 100.

When intercom information including identification information and entry information is received by the first communication unit 61 of the display control device 60, the control unit 63 can display the entry information as shown in the lower part of FIG. 5A based on the identification information. Note that the visitor's name and entry information shown in FIG. 5A may be displayed simultaneously with the second content information. FIG. 5B is a diagram showing a second display example of an image based on intercom information on the display unit 71 of the display device 70.

Note that information related to the equipment systems installed in the apartment complex 100 is not limited to delivery box inventory information. A second example of information related to the equipment systems installed in the apartment complex 100 is information related to the EMS (Energy Management System) installed in the apartment complex 100.

When intercom information including information about the EMS is received by the first communication unit 61 of the display control device 60, the control unit 63 can display information about the EMS (specifically, information indicating the energy consumption of the entire apartment building 100). Figure 6 is a diagram showing a third example of an image based on the intercom information displayed on the display unit 71 of the display device 70.

A third example of information regarding the facility systems installed in the apartment complex 100 is information regarding the elevator system installed in the apartment complex 100.

When intercom information including information about the elevator system is received by the first communication unit 61 of the display control device 60, the control unit 63 can display information about the elevator system (specifically, information indicating the maintenance status of the elevator system). Figure 7 shows a fourth example of an image based on the intercom information displayed on the display unit 71 of the display device 70.

In addition, the intercom information may include information about some areas of the common areas instead of, or in addition to, information about the equipment systems installed in the apartment complex 100.

For example, by operating the intercom master unit 54, it may be possible to reserve some areas of the common areas within the apartment complex 100, such as rooms, parking spaces, and parking spaces with EV (electric vehicle) chargers. In such cases, because the intercom system 50 manages the usage status of each area, the lobby intercom 52 can transmit information about the common areas to the display control device 60 as intercom information.

When intercom information including information about some areas of the common area is received by the first communication unit 61 of the display control device 60, the control unit 63 can display information about some areas of the common area (specifically, information indicating the reservation status of each area). Figure 8 shows a fifth display example of an image based on intercom information on the display unit 71 of the display device 70.

In this way, if the intercom information includes facility-related information, which is at least one of information about the equipment systems installed in the apartment complex 100 and information about some of the common areas, the control unit 63 can display the facility-related information on the display unit 71 of the display device 70.

The above describes an example of displaying an image based on intercom information on the display device 70. Note that when displaying an image based on intercom information, an image displaying an overview and an image displaying details may also be displayed hierarchically in response to an operation. In other words, the control unit 63 may display detailed information (details screen) about the intercom information on the display unit 71 of the display device 70 based on an operation performed on the operation reception unit 66. Furthermore, by taking advantage of the large display unit 71 of the display device 70, an image displaying an overview and an image displaying details may be displayed simultaneously.

[Changing the Display Priority of Second Content Information Based on Display History]
The control unit 63 of the display control device 60 acquires the visitor's identification information from the lobby intercom 52 and displays the second content information on the display unit 71 of the display device 70, thereby storing in the storage unit 64 a display history that associates the identification information with the second content information presented to the visitor having the identification information. The following describes an operation for changing the display priority of the second content information based on such a display history. Figure 9 is a flowchart of the operation for changing the display priority of the second content information based on the display history.

The visitor authenticates themselves at the lobby intercom 52, unlocks or opens the auto-lock door 53, and then passes through the entrance (around the display device 70) (see Figure 2). At this time, the lobby intercom 52 transmits the identification information (e.g., name) of the successfully authenticated visitor to the display control device 60 as intercom information.

The first communication unit 61 of the display control device 60 receives the identification information (S11), and the control unit 63 determines whether the display history of the visitor having the identification information is stored in the memory unit 64 (S12). If the control unit 63 determines that the display history is not stored in the memory unit 64 (No in S12), it displays multiple pieces of second content information on the display unit 71 of the display device 70 based on a predetermined priority order (S13). On the other hand, if the control unit 63 determines that the display history is stored in the memory unit 64 (Yes in S12), it changes the predetermined priority order based on the display history (S14), and displays multiple pieces of second content information on the display unit 71 of the display device 70 based on the changed priority order (S15).

As shown in (a) of FIG. 4, the control unit 63 displays, for example, the second content information with the highest priority in a larger size than the other second content information, and displays the other second content information higher in order of priority. Since details of the second content information are not displayed in (a) of FIG. 4, it can be said that in step S15, the control unit 63 displays at least a portion of the second content information based on the identification information.

The priority order in step S14 is changed based on a predetermined algorithm, for example, such that second content information that has not yet been presented to the visitor and similar second content information are given higher priority. The identification information received in step S11 may include attribute information (such as gender and age group) in addition to personal identification information such as the visitor's name or identification number, and the priority order may be changed taking into account the attribute information in addition to the display history.

In this way, the control unit 63 of the display control device 60 can change the display priority of the second content information based on the display history of the second content information associated with the identification information.

In addition, if the acquisition unit 65 is a camera that can capture facial images of people leaving the apartment complex 100, and the control unit 63 can identify the person's identification information by performing facial authentication using the facial image, the display history can also include a history of the second content information that was displayed while the person was out.

[Changing the Display Priority of Second Content Information Based on Browsing History]
As shown in FIG. 4 above, the second content information selected by the visitor through an operation can be considered to be the second content information viewed by the visitor. Therefore, the control unit 63 of the display control device 60 can acquire the visitor's identification information from the lobby intercom 52 and store in the storage unit 64 a viewing history that associates the identification information with the second content information viewed by the visitor having the identification information. Below, an operation for changing the display priority of the second content information based on such a viewing history will be described. FIG. 10 is a flowchart of the operation for changing the display priority of the second content information based on the viewing history.

The visitor authenticates themselves at the lobby intercom 52, unlocks or opens the auto-lock door 53, and then passes through the entrance (around the display device 70) (see Figure 2). At this time, the lobby intercom 52 transmits the identification information (e.g., name) of the successfully authenticated visitor to the display control device 60 as intercom information.

The first communication unit 61 of the display control device 60 receives the identification information (S21), and the control unit 63 determines whether the browsing history of the visitor having the identification information is stored in the memory unit 64 (S22). If the control unit 63 determines that the browsing history is not stored in the memory unit 64 (No in S22), it displays multiple pieces of second content information on the display unit 71 of the display device 70 based on a predetermined priority order (S23). On the other hand, if the control unit 63 determines that the browsing history is stored in the memory unit 64 (Yes in S22), it changes the predetermined priority order based on the browsing history (S24), and displays multiple pieces of second content information on the display unit 71 of the display device 70 based on the changed priority order (S25).

As shown in (a) of FIG. 4, the control unit 63 displays, for example, the second content information with the highest priority in a larger size than the other second content information, and displays the other second content information with higher priority higher up. Since (all) of the second content information is not displayed in detail in (a) of FIG. 4, it can be said that in step S25, the control unit 63 displays at least a portion of the second content information based on the identification information.

The priority order in step S24 is changed based on a predetermined algorithm, for example, such that second content information that has been viewed many times by the visitor in the past and second content information similar thereto are given a higher priority. The priority order in step S24 may also be changed based on a predetermined algorithm, for example, such that second content information that has been viewed less often by the visitor in the past and second content information similar thereto are given a higher priority. The identification information received in step S21 may include attribute information (such as gender and age group) in addition to personal identification information such as the visitor's name or identification number, and the priority order may be changed taking into account the attribute information in addition to the viewing history.

In this way, the control unit 63 of the display control device 60 can change the display priority of the second content information based on the browsing history of the second content information associated with the identification information.

In addition, if the acquisition unit 65 is a camera that can capture facial images of people leaving the apartment complex 100, and the control unit 63 can identify the identification information of the people by performing facial authentication using the facial images, the browsing history can also include a history of the second content information viewed while away from home.

The control unit 63 may also change the priority of the second content information by comprehensively considering both the display history and browsing history of the second content information. The priority may also be changed based on at least one of the display history and browsing history of the first content information displayed on the display unit 54a of the intercom master unit 54. In other words, the control unit 63 may change the display priority of the second content information based on at least one of the display history of the second content information, the browsing history of the second content information, the display history of the first content information, and the browsing history of the first content information, which are associated with the identification information.

The display history of the second content information, the browsing history of the second content information, the display history of the first content information, and the browsing history of the first content information are cleared (reset), for example, when new content information is distributed. New content information may be distributed periodically or irregularly.

[Feedback on impressions and views]
4A is displayed once each time information indicating that there is a person in the vicinity is acquired by the acquisition unit 65 of the display control device 60. Therefore, the control unit 63 may count (aggregate) the number of times each of the plurality of pieces of second content information is displayed, and cause the second communication unit 62 to transmit feedback information indicating the number of times each of the plurality of pieces of second content information is displayed to the distribution system 20. In other words, the second communication unit 62 may transmit feedback information regarding the second content information based on information regarding people acquired by the acquisition unit 65.

This allows the provider of the second content information to know the number of times the second content information has been displayed.

Furthermore, when various images based on intercom information (such as the multiple images shown in Figures 5 to 8) are displayed on the display device 70, each of the multiple images can be said to be displayed once each time information indicating the presence of a person in the vicinity is acquired by the acquisition unit 65 of the display control device 60. Therefore, the control unit 63 may count (tally) the number of times the multiple images based on the intercom information are displayed, and cause the first communication unit 61 to transmit feedback information indicating the number of times the multiple images have been displayed to the intercom system 50. In other words, the first communication unit 61 may transmit feedback information regarding the intercom information based on information about people acquired by the acquisition unit 65.

This allows the administrator of the intercom system 50 to understand the number of times multiple images are displayed based on the intercom information.

Furthermore, as described above, the control unit 63 can consider the second content information selected by the visitor through an operation as the second content information viewed by the visitor. Therefore, the control unit 63 may count (aggregate) the number of times each of the multiple pieces of second content information has been viewed, and cause the second communication unit 62 to transmit feedback information indicating the number of times each of the multiple pieces of second content information has been viewed to the distribution system 20. In other words, the second communication unit 62 may transmit feedback information regarding the second content information based on an operation performed on the operation reception unit 66.

This allows the provider of the second content information to know the number of times the second content information has been viewed.

Furthermore, when displaying images based on intercom information, if an image showing an overview and an image showing details are displayed hierarchically in response to an operation, the control unit 63 can consider the image selected by the operation to be the image that has been viewed. Therefore, the control unit 63 may count (aggregate) the number of times that multiple images based on the intercom information have been viewed, and cause the first communication unit 61 to transmit feedback information indicating the number of times the multiple images have been viewed to the intercom system 50. In other words, the first communication unit 61 may transmit feedback information regarding the intercom information based on an operation performed on the operation reception unit 66.

This allows the administrator of the intercom system 50 to understand the number of times multiple images have been viewed based on the intercom information.

As described above, at least one of the first communication unit 61 and the second communication unit 62 may transmit feedback information regarding at least one of intercom information and second content information based on at least one of information about a person acquired by the acquisition unit 65 and an operation performed on the operation reception unit 66.

The number of times the second content information has been displayed and the number of times the second content information has been viewed are cleared (reset), for example, when new second content information is distributed. New content information may be distributed periodically or irregularly.

Furthermore, each of the multiple intercom master units 54 may transmit feedback information indicating the number of times the first content information displayed on the display unit 54a has been displayed or viewed to the distribution system 20. Each of the multiple intercom master units 54 transmits feedback information indicating the number of times the first content information displayed on the display unit 54a has been displayed or viewed to the distribution system 20. Because the feedback information includes the identification information of the private unit (apartment number), the distribution system 20 can tally the number of times it has been displayed or viewed for each private unit. Note that the feedback information may also be statistical information that does not include the identification number of the private unit (apartment number) and does not specify the private unit (such as the number of units viewed, the number of times it has been displayed/viewed, the time of viewing, classification by resident attributes, etc.). In this case, the statistical information that does not specify the private unit is generated, for example, by the intercom system 50.

The number of times the first content information has been displayed and the number of times the first content information has been viewed are cleared (reset), for example, when new first content information is distributed. New first content information may be distributed periodically or irregularly.

[Modification]
In the above embodiment, the identification information is primarily personal identification information that can identify an individual, but it may also be attribute information. For example, if the authentication unit 52a of the lobby intercom 52 performs face authentication, the identification information may include at least one of personal identification information based on face authentication and attribute information (gender and age group) based on face authentication.

In the above embodiments, the processing described as using personal identification information may be interpreted as processing using attribute information. For example, changing the display priority of second content information based on display history or browsing history may be performed based on attribute information.
