The intercom device and the control system incorporating the intercom device according to the present invention will be described below with reference to the drawings.

Figure 1 is a block diagram showing an intercom device 1 according to the present invention. As shown in Figure 1, the intercom device 1 is used, for example, in an apartment complex M, where multiple dwelling units are partitioned within a single building. The intercom device 1 comprises a collective entrance unit 10 (10A-10C: an example of an entrance sub-unit), a management room master unit 20, a room master unit 30, and a control device 40. The collective entrance unit 10, the management room master unit 20, the room master unit 30, and the control device 40 are connected to each other via a network (in this example, a LAN: Local Area Network) over which communication is performed according to a general-purpose protocol.

The collective entrance unit 10A-10C (hereinafter collectively referred to as collective entrance unit 10) are installed at the building entrance or common space of the collective housing complex M. The collective entrance unit 10 is configured, for example, to be able to call the room master unit 30 and the management room master unit 20 in the collective housing complex M. The collective entrance unit 10 is also configured, for example, to be able to capture video of visitors.

Examples of collective entrance machines 10 include contact-type collective entrance machines equipped with a stationary operation reception unit (hardware device) as shown in collective entrance machines 10A and 10C, and non-contact-type collective entrance machines equipped with an aerial display-type touch display as shown in collective entrance machine 10B. For example, the contact-type collective entrance machine 10A is equipped with an operation unit 11 for inputting room numbers, etc., a call unit 12 for talking with residents, etc., a camera 13 for photographing visitors, and a display unit 14 for displaying various information. The non-contact-type collective entrance machine 10B is equipped with a camera 120 for photographing visitors and an aerial touch display 100 for displaying images in the air (hereinafter referred to as an aerial image).

The collective entrance machines 10A-10C store unique information (e.g. collective entrance machine ID: identification, etc.) that identifies each collective entrance machine. The collective entrance machine 10 is connected to the control device 40 via an intercom line (dedicated line) L1. The collective entrance machine 10 can communicate with the room master machine 30 and the management room master machine 20 via the control device 40. In this example, three collective entrance machines (collective entrance machines 10A-10C) are connected to the control device 40, but the number of machines that can be connected is not limited to this number.

The management room master unit 20 is installed in the management room of the apartment building. The management room master unit 20 includes an operation unit 21, a call unit 22, a display unit 23, etc. The management room master unit 20 stores unique information (e.g., a management room master unit ID, etc.) that identifies the management room master unit. The management room master unit 20 is connected to the control device 40 via the intercom line L2. The management room master unit 20 can communicate with the room master units 30, the collective entrance unit 10, etc. via the control device 40.

The room master unit 30 is connected to the control unit 40 via the intercom line L3. The room master unit 30 can communicate with the collective entrance unit 10, the management room master unit 20, and the like via the control unit 40.

The control device 40 controls communication between the collective entrance unit 10, the management room master unit 20, and the room master unit 30, which are connected via an intercom line. The control device 40 stores unique information (e.g., a control device ID) that identifies the control device.

Figure 2 is a schematic diagram of a collective entrance device 10B equipped with an aerial touch display 100. As shown in Figure 2, the collective entrance device 10B is equipped with an aerial touch display 100 capable of displaying an aerial image G toward a visitor W, and a control unit 110 that controls the operation of the aerial touch display 100.

The aerial touch display 100 comprises a display device 101, an optical member 102, and a detection unit 103.

The display device 101 is a device that emits light P for generating an aerial image G. The display device 101 is composed of, for example, a light source (such as an LED (Light Emitting Diode)), a lens unit, a liquid crystal display, etc. The display device 101 is communicatively connected to the control unit 110. The aerial image G is formed, for example, in a rectangular shape (see FIG. 7).

The optical element 102 is a member that reflects and transmits the light P emitted from the display device 101, and focuses an aerial image G in a specified space to be displayed to the visitor W. The light emitted from the display device 101 is reflected and transmitted by the optical element 102, and is focused at a position that is plane-symmetrical to the optical element 102. The focused light diverges again, and is observed by the visitor W as an aerial image G in the space above the aerial touch display 100.

The detection unit 103 detects operation input by the visitor W with respect to the aerial image G. The detection unit 103 is composed of a three-dimensional distance sensor capable of measuring the distance to an object in space. The detection unit 103 is communicatively connected to the control unit 110.

The control unit 110 controls the display device 101 and the detection unit 103 of the aerial touch display 100. For example, the control unit 110 determines the spatial position and movement of the visitor W's fingertips based on information acquired by the detection unit 103. The control unit 110 also changes the display content of the aerial image G generated by the light P emitted from the display device 101 in response to operation input from the visitor W to the aerial image G. The control unit 110 also changes the display position, display angle, display mode, etc. of the aerial image G generated by the light P emitted from the display device 101 in response to the visitor W operating the aerial image G.

First Embodiment
3 is a diagram showing the aerial touch display 100 of the collective entrance device 10B in the intercom device 1 of the first embodiment. As shown in FIG. 3, the collective entrance device 10B includes a camera 120 (an example of a sensor) for capturing an image of a visitor W in front of the aerial touch display 100. The camera 120 is disposed in a position capable of capturing a facial image of the visitor W. For example, the camera 120 is disposed in the space above and behind the aerial touch display 100.

The intercom device 1 of the first embodiment operates, for example, as follows.

The camera 120 captures an image of the visitor W and detects the eye level of the visitor W from the captured facial image of the visitor W. The camera 120 transmits the detected eye level information of the visitor W to the control unit 110.

The control unit 110 determines the display position of the aerial image G to be displayed to the visitor W based on the received eye-line information of the visitor W. The control unit 110 compares the eye-line height of the visitor W with a predetermined threshold value, and determines the display position of the aerial image G based on the comparison result. When the eye-line height of the visitor W is equal to or greater than the predetermined threshold value, the control unit 110 sets the display position of the aerial image G higher than when the eye-line height is less than the predetermined threshold value.

For example, in the case of visitor W1, the control unit 110 compares the eye height H1 of visitor W1 with a predetermined threshold value, and when the eye height H1 is equal to or greater than the predetermined threshold value, displays the display position of the aerial image G1 to be displayed to visitor W1 at a height h1. In the case of visitor W2, the control unit 110 compares the eye height H2 of visitor W2 with a predetermined threshold value, and when the eye height H2 is less than the predetermined threshold value, displays the display position of the aerial image G2 to be displayed to visitor W2 at a height h2. The reference position for height is the position of the optical member 102.

The control unit 110 sets the height h1 of the display position of the aerial image G1 displayed to a visitor W1 whose eye line height H1 is equal to or greater than a predetermined threshold value to be higher than the height h2 of the display position of the aerial image G2 displayed to a visitor W2 whose eye line height H2 is less than the predetermined threshold value.

The control unit 110 changes the display position where the aerial image G is displayed to a predetermined display position by changing the position and angle of the display device 101 in the housing 100a of the aerial touch display 100. Specifically, the control unit 110 changes the display position of the aerial image G by changing the facing position and facing angle of the display device 101 with respect to the optical member 102. For example, when the aerial image G2 is displayed at a position lower than the aerial image G1, the position of the display device 101 in the housing 100a may be higher than the position of the display device 101 when displaying the aerial image G1. In this way, when displaying the aerial image G2, the angle of incidence of the light P emitted from the display device 101 with respect to the optical member 102 is made acuter than the angle of incidence when the aerial image G1 is displayed, so that the aerial image G2 can be displayed at a position lower than the aerial image G1.

As described above, the intercom device 1 of the first embodiment includes a collective entrance device 10B (an example of an entrance slave device) for a visitor W to call a resident and talk to him/her, and a room master device 30 for a resident to respond to a call from the collective entrance device 10B. The collective entrance device 10B includes an aerial touch display 100 for displaying an aerial image G toward the visitor W, and a control unit 110 for changing the display position of the aerial image G. The aerial touch display 100 includes a display device 101 that emits light for generating the aerial image G, an optical member 102 that reflects and transmits light to form an image of the aerial image G in a predetermined space, and a detection unit 103 that detects operation input by the visitor W on the aerial image G. With this configuration, the display position of the aerial image G used as the operation reception unit of the collective entrance device 10B can be changed, greatly improving the operability of the collective entrance device 10B equipped with the aerial touch display 100.

The intercom device 1 further includes a camera 120 that is arranged in a predetermined space and can detect the eye height H of the visitor W. The control unit 110 changes the display position of the aerial image G based on the eye height H of the visitor W detected by the camera 120. Specifically, when the eye height H of the visitor W is equal to or greater than a predetermined threshold, the control unit 110 raises the display position of the aerial image G higher than when the eye height H is lower than the predetermined threshold. In this way, by changing the display position of the aerial image G according to the eye height H of the visitor W, the operability of the collective entrance device 10B equipped with the aerial touch display 100 is not impaired, for example, even when the visitor W is a person shorter than normal (e.g., a child) or a person taller than normal (e.g., a foreigner). Therefore, good operability can be provided for any visitor W.

In the above first embodiment, the camera 120 is installed in the space above and behind the aerial touch display 100, but this is not limited to the above example. For example, the camera 120 may be installed in the housing of the aerial touch display 100. In addition, if a contact-type collective entrance machine 10A equipped with a stationary hardware device is installed together with the aerial touch display 100, a camera common to the camera 13 installed in the collective entrance machine 10A may be used.

(Modification)
FIG. 4 is a diagram showing a modified example of the air touch display 100 shown in FIG.
The operation of the intercom device 1 equipped with the modified aerial touch display 100A is, for example, as follows.

The camera 120 captures an image of the visitor W and detects the eye level of the visitor W from the captured facial image of the visitor W. The camera 120 transmits the detected eye level information of the visitor W to the control unit 110A.

The control unit 110A determines the display angle of the aerial image G to be displayed to the visitor W based on the received line-of-sight information of the visitor W. For example, the control unit 110A compares the height of the visitor W's line of sight with a predetermined threshold value, and determines the display angle of the aerial image G based on the comparison result.

When the height of the visitor W's line of sight is higher than a predetermined threshold, the control unit 110A sets the display angle of the aerial image G3 so that, for example, the bottom side bs of the rectangular aerial image G3 is tilted in a direction closer to the visitor W than the top side ts. Also, when the height of the visitor W's line of sight is higher than a predetermined threshold, the control unit 110A may set the display angle of the aerial image G3 so that the image surface of the aerial image G3 is approximately perpendicular to the front-to-rear direction of the aerial touch display 100A. Note that the side of the aerial touch display 100A that the visitor W faces is defined as the front side of the aerial touch display 100A.

For example, when visitor W's line of sight is high (if the visitor is tall), the display angle of aerial image G3 may be set so that the elevation angle of the image plane is large as shown in aerial image G3, and when visitor W's line of sight is low (if the visitor is short), the display angle of aerial image G4 may be set so that the elevation angle of the image plane is smaller than that of aerial image G3 as shown in aerial image G4.

In addition, when the height of the visitor W's line of sight is equal to or lower than a predetermined threshold value, the control unit 110A may set the display angle of the aerial image G5 so that, for example, the upper side ts of the rectangular aerial image G5 is inclined in a direction closer to the visitor W than the lower side bs, as shown in FIG. 4 for the aerial image G5.

The control unit 110A changes the display angle at which the aerial image G is displayed to a predetermined display angle by changing the position and angle of the display device 101 in the housing 100Aa of the aerial touch display 100. Specifically, the control unit 110A changes the display angle of the aerial image G by changing the facing position and facing angle of the display device 101 with respect to the optical member 102. For example, when displaying the aerial image G4, the position of the display device 101 in the housing 100a may be made higher than the position of the display device 101 when displaying the aerial image G3, and the angle of the display device 101 may be changed. In this way, when displaying the aerial image G4, the angle of incidence of the light P emitted from the display device 101 with respect to the optical member 102 is made more acute than the angle of incidence when displaying the aerial image G3, so that the aerial image G4 can be displayed at a lower position than the aerial image G3 and with an elevation angle of the image plane smaller than that of the aerial image G3.

As described above, according to the intercom device 1 equipped with the modified aerial touch display 100A, the collective entrance device 10B is equipped with the aerial touch display 100A for displaying the aerial image G toward the visitor W, and the control unit 110A for changing the display angle of the aerial image G. As a result, the display angle of the aerial image G used as the operation reception unit of the collective entrance device 10B can be changed, greatly improving the operability of the collective entrance device 10B equipped with the aerial touch display 100A.

In addition, with the intercom device 1 equipped with the modified aerial touch display 100A, the display angle of the aerial image G can be changed according to the eye height H of the visitor W detected by the camera 120. Specifically, when the eye height of the visitor W is equal to or lower than a predetermined threshold, the display angle can be changed so that the upper side ts of the rectangular aerial image G is inclined in a direction closer to the visitor W than the lower side bs. Therefore, for example, even if the visitor W is a person shorter than normal (such as a child), the operability of the collective entrance unit 10B is not impaired.

In addition, with the intercom device 1 equipped with the modified aerial touch display 100A, when the height of the visitor W's line of sight is higher than a predetermined threshold, the display angle is changed so that the aerial image G is vertical, or so that the bottom side bs is tilted closer to the visitor W than the top side ts. As a result, when a person of normal height or taller than normal operates the aerial touch display 100A, the aerial image G is displayed at the same angle as the operation section of a conventional collective entrance unit 10A as a stationary hardware device, so that the aerial touch display 100A can be operated without any discomfort.

Second Embodiment
Fig. 5 is a schematic diagram of a control system S11 that controls the intercom device 1 of the second embodiment. The control system S11 is used in an intercom system equipped with the intercom device 1. As shown in Fig. 5, the control system S11 includes a collective entrance unit 10A (an example of a hardware device), a collective entrance unit 10B, a camera 120, a room master unit 30 (see Fig. 1), and a control device 40 (see Fig. 1).

As described in FIG. 1, the collective entrance machine 10A has an operation unit 11 that serves as an operation reception unit. If the display unit 14 of the collective entrance machine 10A is configured as a touch display, the display unit 14 functions as the operation reception unit. The collective entrance machine 10A also has a control unit 15 that controls the operation of the collective entrance machine 10A.

As described in FIG. 2, the collective entrance unit 10B has an aerial touch display 100 and a control unit 110. The aerial touch display 100 has a display device 101, an optical member 102, and a detection unit 103, and displays an aerial image G toward a visitor W (an example of a user). The control unit 110 controls the operation of the aerial touch display 100. The control unit 110 is also connected to be able to communicate with the control unit 15 of the collective entrance unit 10A via the intercom line L1.

Camera 120 is a camera that can detect visitor W and capture an image of the detected visitor W. In this embodiment, since collective entrance machine 10A and collective entrance machine 10B are installed side by side, a single camera 120 is provided as a camera shared by both collective entrance machines. Camera 120 is connected to collective entrance machine 10A and collective entrance machine 10B so that they can communicate with each other. Note that when collective entrance machine 10A and collective entrance machine 10B are installed side by side, for example, camera 13 installed in collective entrance machine 10A may be used as a camera shared by both collective entrance machines.

The room master unit 30 (an example of a calling device) is a device that can be called based on a calling operation from the collective entrance unit 10A or collective entrance unit 10B, as described in FIG. 1.

As described in FIG. 1, the control device 40 is connected to the collective entrance device 10 and the room master device 30, and controls communication between the collective entrance device 10 and the room master device 30. When a call operation is input to the collective entrance device 10A and the collective entrance device 10B, the control device 40 executes a call process to call the room master device 30 based on the call signal received from the control unit 15 of the collective entrance device 10A and the control unit 110 of the collective entrance device 10B.

An example of the operation of the control system S11 having such a configuration will be described with reference to FIG.
First, the control system S11 detects a visitor W by the camera 120 (step S1). The camera 120 starts capturing an image of the detected visitor W (step S2). The camera 120 also transmits a detection signal notifying the fact that the visitor W has been detected to the collective entrance unit 10A and the collective entrance unit 10B.

Next, the control unit 15 of the collective entrance unit 10A transitions from a standby state to an operating state based on the received detection signal, displays a specified image on the display unit 14, and sets the operation unit 11 to an operable reception state (step S3). The control unit 110 of the collective entrance unit 10B transitions from a standby state to an operating state based on the received detection signal, and starts displaying the aerial image G (step S4). As a result, the collective entrance unit 10A and the collective entrance unit 10B transition to an input waiting state, waiting for operation input from the visitor W.

Next, for example, suppose that a first operation input is made by visitor W to the operation unit 11 of collective entrance unit 10A, and furthermore, a second operation input is made by visitor W to the aerial image G of collective entrance unit 10B. In this case, the control unit 15 of collective entrance unit 10A accepts the first operation input (step S5). The control unit 110 of collective entrance unit 10B accepts the second operation input (step S6). The control units 15 and 110 send and receive the accepted reception information to each other, and determine which of the first and second operation inputs was accepted later. Specifically, the control units 15 and 110 determine whether the first operation input was accepted later than the second operation input (step S7).

If it is determined that the first operation input was received after the second operation input (Yes in step S7), the control unit 15 and the control unit 110 cancel the process based on the first operation input received first, and execute the process based on the first operation input received later (step S8). On the other hand, if it is determined that the first operation input was not received after the second operation input (No in step S7), the control unit 15 and the control unit 110 cancel the process based on the first operation input received first, and execute the process based on the second operation input received later (step S9).

For example, suppose visitor W initially performs a second operation input on the aerial image G of collective entrance unit 10B, but becomes confused about the operation method midway through the operation, so stops the second operation input and performs a first operation input on the operation unit 11 of collective entrance unit 10A. In this case, control unit 15 and control unit 110 cancel the processing based on the first second operation input to collective entrance unit 10B, and execute the processing based on the later first operation input to collective entrance unit 10A.

For example, suppose visitor W first starts a first operation input to the operation unit 11 of collective entrance unit 10A, but stops touching the operation unit 11 midway through the operation and performs a second operation input to the aerial image G of collective entrance unit 10B. In this case, the control unit 15 and control unit 110 cancel the process based on the first operation input to collective entrance unit 10A that was performed first, and then execute the process based on the second operation input to collective entrance unit 10B that was performed later.

Moreover, the control system S11 may operate, for example, as follows.
First, similarly to the above operation example, collective entrance device 10A displays a predetermined image on display unit 14 and sets operation unit 11 to an operable reception state based on the detection signal received from camera 120. Collective entrance device 10B starts displaying aerial image G based on the detection signal received from camera 120.

Next, for example, suppose that one of the first operation input by visitor W to the operation unit 11 of collective entrance unit 10A and the second operation input by visitor W to the aerial image G of collective entrance unit 10B is accepted, and the call process of the room master unit 30 corresponding to that operation input is started. Then, suppose that after the call process is started, the other of the first operation input by visitor W to the operation unit 11 of collective entrance unit 10A and the second operation input by visitor W to the aerial image G of collective entrance unit 10B is received. In this case, the control unit 15 of collective entrance unit 10A and the control unit 110 of collective entrance unit 10B send and receive reception information of the operation inputs they have accepted, and determine which of the first and second operation inputs was accepted first, and confirm that the call process of the room master unit 30 corresponding to the first operation input has been started. Based on the determination result and the confirmation result, the control unit 15 and the control unit 110 stop accepting the operation input of the other (subsequent operation input) and execute the process (processing after the call process) based on the operation input of one side (initial operation input).

For example, visitor W first performs a second operation input on the aerial image G of the collective entrance unit 10B, and the call process of the room master unit 30 corresponding to the second operation input is started. However, after the call process is started, visitor W becomes worried that the operation may have been incorrect, and starts a first operation input on the operation unit 11 of the collective entrance unit 10A. In this case, the control unit 15 and the control unit 110 do not accept the first operation input started later on the collective entrance unit 10A, and continue to execute the call process based on the first second operation input on the collective entrance unit 10B.

This process is also the same if the order of the second operation input to the aerial image G of the collective entrance unit 10B and the first operation input to the operation unit 11 of the collective entrance unit 10A is reversed, and once the call process based on the operation input made first to the collective entrance unit is started, any subsequent operation inputs to the collective entrance unit will not be accepted.

As described above, the control system S11 that controls the intercom device 1 of the second embodiment includes a collective entrance device 10A (hardware device) having an operation unit 11, an aerial touch display 100 (collective entrance device 10B) having a display device 101, an optical member 102, and a detection unit 103 for displaying an aerial image G, and a control unit 15 that controls the collective entrance device 10A and a control unit 110 that controls the aerial touch display 100. When the control units 15 and 110 receive both a first operation input by a visitor W to the operation unit 11 and a second operation input by a visitor W to the aerial image G, they cancel the processing based on the first operation input of the first operation input and the second operation input that was received first, and execute the processing based on the second operation input that was received later. With this configuration, even if there is a mixture of operation inputs to the contact-type collective entrance unit 10A, which is a hardware device, and operation inputs to the non-contact-type collective entrance unit 10B, which touches an aerial image, the later operation input is prioritized, thereby improving the control quality of the intercom device 1, which has both hardware and an aerial image.

The control system S11 that controls the intercom device 1 of the second embodiment further includes a camera 120 that detects a visitor W. The control unit 110 starts displaying the aerial image G when the camera 120 detects a visitor W. With this configuration, the aerial image G is displayed only when a visitor W is present, which reduces the load on the control system S11 and reduces the power consumption of the aerial touch display 100.

The control system S11 for controlling the intercom device 1 of the second embodiment further includes a room master unit 30 that can be called by receiving a first operation input to the operation unit 11 of the collective entrance unit 10A or a second operation input to the aerial image G of the collective entrance unit 10B. Then, when the control unit 15, 110 starts the call processing of the room master unit 30 by receiving one of the first operation input and the second operation input, and then receives the other of the first operation input and the second operation input, it executes processing based on one operation input without accepting the other operation input. If the other operation input is given priority after the call processing of the room master unit 30 is started by one operation input, there is a risk that the called party will be confused and appropriate control will not be possible. In contrast, according to the above configuration, after the call processing by one operation input is started, the other operation input is canceled without being accepted, and processing based on one operation input is continued, so that the called party is not confused and control quality can be maintained.

In the above second embodiment, the control system S11 is used in an intercom system, but this is not limiting. For example, the control system S11 may be used in a nurse call system. In this case, a conventional nurse call master unit installed in a nurse station corresponds to a contact-type hardware device. An aerial touch display that displays the aerial image G to medical staff is installed next to the conventional nurse call master unit in the nurse station. A nurse call handset that allows a patient to call a nurse or that receives a call from the nurse call master unit corresponds to a calling device.

Third Embodiment
Next, an intercom system S12 equipped with the intercom device 1 of the third embodiment will be described with reference to Fig. 5 again. As shown in Fig. 5, the intercom device 1 in the intercom system S12 includes a contact-type collective entrance device 10A equipped with a stationary hardware device, a non-contact-type collective entrance device 10B that touches an aerial image G, a camera 120, and a room master device 30 (see Fig. 1).

The collective entrance device 10A has an operation unit 11, a display unit 14, and a control unit 15, similar to the configuration described in the second embodiment above.

The collective entrance device 10B has a first sensor 210 and a second sensor 220 in addition to the aerial touch display 100 and control unit 110, which are configured as described in the second embodiment above. The first sensor 210 and the second sensor 220 are communicatively connected to the control unit 110. The aerial touch display 100 has a display device 101, an optical member 102, and a detection unit 103, and displays an aerial image G toward the visitor W. The control unit 110 controls the operation of the aerial touch display 100.

The first sensor 210 detects the opening and closing of the first entrance K1 of the apartment building M. By detecting the opening and closing of the first entrance K1, the first sensor 210 detects that a visitor W has passed through the first entrance K1. The second sensor 220 detects the opening and closing of the second entrance K2 of the apartment building M. By detecting the opening and closing of the second entrance K2, the second sensor 220 detects that a visitor W has passed through the second entrance K2. The first entrance K1 and the second entrance K2 are automatic doors that open and close upon detecting the presence or absence of a visitor W.

The collective entrance unit 10A and the collective entrance unit 10B are installed at the building entrance E2, which is provided between the first entrance K1 and the second entrance K2 of the apartment building M. The first sensor 210 is disposed near the first entrance K1, which is disposed between the building entrance E2 and the outside E1. The second sensor 220 is disposed near the second entrance K2, which is disposed between the building entrance E2 and the living area E3.

As described in the second embodiment above, the camera 120 detects a visitor W and captures an image of the detected visitor W. As described in the second embodiment above, the room master unit 30 is a device that can be called based on a call operation from the collective entrance unit 10A or the collective entrance unit 10B.

The intercom device 1 in the intercom system S12 operates, for example, as follows.
When a visitor W to the apartment complex M passes through the first entrance K1, the first sensor 210 detects the opening and closing operation of the first entrance K1, and transmits a detection signal indicating the detection to the control unit 110.

The control unit 110 starts displaying the aerial image G toward the visitor W based on the detection signal received from the first sensor 210.

Next, when the visitor W performs a predetermined operation input on the displayed aerial image G, for example, the second entrance K2 is opened. Then, when the visitor W passes through the second entrance K2, the second sensor 220 detects the opening and closing operation of the second entrance K2 and transmits a detection signal indicating the detection to the control unit 110.

The control unit 110 stops displaying the aerial image G based on the detection signal received from the second sensor 220.

As described above, the intercom device 1 of the third embodiment includes a collective entrance device 10B for a visitor W to call a resident and talk to him, and a room master device 30 for the resident to respond to the call from the collective entrance device 10B. The collective entrance device 10B is an aerial touch display 100 for displaying an aerial image G to a visitor W, and includes a display device 101 that emits light for generating the aerial image G, an optical member 102 that reflects and transmits light to form an aerial image G in a predetermined space, and a detection unit 103 that detects the operation input of the visitor W on the aerial image G. The control unit 110 controls the aerial touch display 100, and a first sensor 210 that detects the visitor W. The control unit 110 starts displaying the aerial image G when the visitor W is detected by the first sensor 210. According to this configuration, the operability can be improved by using the aerial touch display 100 as the collective entrance device 10B. Furthermore, the aerial image G is displayed only when a visitor W is present, which reduces the power consumption of the aerial touch display 100.

Furthermore, according to the third embodiment of the intercom device 1, the first sensor 210 is placed near the first entrance K1, which is installed between the building entrance E2 where the collective entrance device 10B is installed and the outside E1, and the control unit 110 starts displaying the aerial image G based on the first sensor 210 detecting whether the first entrance K1 is open or closed. Therefore, the timing at which the display of the aerial image G starts upon the arrival of the visitor W can be controlled with a simple configuration.

The intercom device 1 of the third embodiment further includes a second sensor 220 disposed near a second entrance K2 installed between the building entrance E2 and the residential area E3. The control unit 110 stops the display of the aerial image G based on the second sensor 220 detecting the opening or closing of the second entrance K2. With this configuration, the display of the aerial image G is stopped based on the visitor W finishing operating the aerial image G on the aerial touch display 100, so that the effect of reducing the power consumption of the aerial touch display 100 can be further enhanced.

(Fourth embodiment)
7 to 9, examples of aerial images displayed by the aerial touch display 100 of the entrance collective unit 10B in the intercom device 1 of the fourth embodiment will be described.

The collective entrance device 10B is equipped with a camera 120 for capturing an image of a visitor W in front of the aerial touch display 100. The camera 120 is a camera capable of detecting the attributes of the visitor W based on the captured facial image of the visitor W. The attributes of the visitor W include, for example, the height and age of the visitor W, and whether or not the visitor W is a person associated with the collective housing complex M. The fact that the visitor W is a person associated with the collective housing complex M is determined in advance by capturing a facial image and registering it in the collective entrance device 10B. The associated person may include, for example, a resident of the collective housing complex M, the resident's relatives, friends, etc. The camera 120 is installed, for example, in the space above and behind the aerial touch display 100, as described in the first embodiment above.

Figure 7 shows the first display mode of the aerial image G displayed by the aerial touch display 100. As shown in Figure 7, the aerial image G in the first display mode is provided with a visitor image display section C1 and a call operation reception section C2. The visitor image display section C1 displays a facial image of the visitor W captured by the camera 120. The call operation reception section C2 displays a numeric keypad 41 for inputting the room number to be called, a call button 42 to be pressed after inputting the room number, and a cancel button 43 with which the input number can be cancelled.

Figure 8 shows the second display mode of the aerial image G displayed by the aerial touch display 100. As shown in Figure 8, the entire area of the aerial image G in the second display mode is composed of the call operation reception section D. The call operation reception section D is provided with an operation message section D1 in which the operation content of the aerial image G is displayed, a first operation section D2 in which a numeric keypad 51 for inputting the room number to be called is displayed, and a second operation section D3 in which a call button 52 to be pressed after inputting the room number is displayed. The second display mode is a mode with a simpler display mode than the first display mode shown in the call operation reception section C2 of Figure 7. The second display mode is, for example, a mode in which the call operation reception section D includes fewer operation buttons and the size of the operation buttons is larger than that of the first display mode. In addition, the second display mode is a mode in which the displayed characters are composed only of hiragana.

9 shows a third display mode of the aerial image G displayed by the aerial touch display 100. As shown in FIG. 9, the aerial image G in the third display mode is provided with a visitor image display section F1 and a call operation reception section F2. The visitor image display section F1 displays a face image of the visitor W captured by the camera 120. The call operation reception section F2 displays an operation message 61 indicating the operation content of the aerial image G, a room number 62 indicating the visitor in the apartment building M selected on the aerial touch display 100 side, and a call button 63 for calling the selected room number. The third display mode is a mode that is displayed when the visitor W is determined to be a person associated with the apartment building M. In the third display mode, in order to improve the operability of inputting a call for the associated visitor W, for example, the input operation process of the room number is omitted.

The aerial touch display 100 in the intercom device 1 of the fourth embodiment operates, for example, as follows.
The camera 120 captures an image of the visitor W and detects the height and age of the visitor W from the captured facial image of the visitor W. The camera 120 transmits the detected attribute information of the visitor W, such as the height and age, to the control unit 110.

The control unit 110 determines whether the height or age of the visitor W is equal to or greater than a predetermined threshold based on the attribute information of the visitor W received from the camera 120. If the control unit 110 determines that the height or age of the visitor W is equal to or greater than the predetermined threshold, it displays a first display mode in which a numeric keypad 41, a call button 42, a cancel button 43, etc. are displayed in the call operation reception section C2 of the aerial image G, as shown in FIG. 7.

On the other hand, if the control unit 110 determines that the height or age of visitor W is lower than a predetermined threshold, it displays a second display mode in which an operation message section D1, a first operation section D2, and a second operation section D3 are provided in the call operation reception section D of the aerial image G, as shown in FIG. 8. The control unit 110 displays the operation content in hiragana in the operation message section D1, for example, "Please enter the room number and then press 'Call'." Then, the first operation section D2 and the second operation section D3 display the minimum number of buttons that can execute the operation content.

Furthermore, the aerial touch display 100 in the intercom device 1 of the fourth embodiment may operate, for example, as follows.
Camera 120 captures an image of visitor W and detects from the captured facial image of visitor W whether visitor W is a person associated with apartment complex M. Camera 120 transmits the detected attribute information to control unit 110.

When the control unit 110 recognizes the visitor W as a person associated with the apartment complex M based on the attribute information of the visitor W received from the camera 120, it displays a third display mode in which an operation message 61, a room number 62, a call button 63, etc. are displayed in the call operation reception section F2 of the aerial image G as shown in FIG. 9. When the control unit 110 detects that the visitor W is an associated visitor W, it displays the room number associated with the visitor W, for example, "103", without the visitor W inputting an operation, and displays, for example, "If the displayed room number is correct, please press "Call" (call button 63)" as the operation message 61. In this case, when the call button 63 is pressed, for example, the door to the apartment complex entrance is unlocked when the visitor W is a resident of the apartment complex M, and a call process to the room number "103" is started when the visitor W is a friend.

On the other hand, if the control unit 110 recognizes that the visitor W is not a person associated with the apartment building M, it displays a first display mode in which a numeric keypad 41, a call button 42, a cancel button 43, etc. are displayed in the call operation reception section C2 of the aerial image G, as shown in FIG. 7.

For example, if the control unit 110 determines that the height or age of the visitor W is lower than a predetermined threshold value and that the visitor W is associated with the apartment building M, the control unit 110 may display the room number associated with the visitor W in the first operation unit D2 of the call operation reception unit D in the aerial image G shown in FIG. 8 without the visitor W having to enter any input, and may display "Please press 'Call'" in hiragana in the operation message unit D1.

As described above, the intercom device 1 of the fourth embodiment includes a collective entrance device 10B for a visitor W to call a resident and to talk to the resident, and a room master device 30 for the resident to respond to the call from the collective entrance device 10B. The collective entrance device 10B is an aerial touch display 100 for displaying an aerial image G to a visitor W, and includes a display device 101 that emits light for generating the aerial image G, an optical member 102 that reflects and transmits light to form an image of the aerial image G in a predetermined space, and a detection unit 103 that detects an operation input by the visitor W to the aerial image G, and a control unit 110 that controls the aerial touch display 100. The control unit 110 changes the display mode of the call operation reception unit C2 included in the aerial image G. According to this configuration, the display mode of the call operation reception unit C2 displayed on the aerial image G can be changed in the aerial touch display 100 used as the collective entrance device 10B, so that the operability of the collective entrance device 10B is greatly improved.

The fourth embodiment of the intercom device 1 further includes a camera 120 that is placed in a specified space and is capable of detecting the attributes of the visitor W. The control unit 110 then changes the display mode of the call operation reception unit C2 based on the attributes detected by the camera 120. With this configuration, by changing the display mode of the call operation reception unit C2 in the aerial image G according to the attributes of the visitor W, such as the height and age of the visitor W, a new collective entrance device 10B with excellent operability can be provided for a variety of visitors W.

Furthermore, according to the fourth embodiment of the intercom device 1, the attribute is at least one of the height and age of the visitor W. Then, when the height or age is equal to or greater than a predetermined threshold, the control unit 110 displays the call operation reception unit C2 in a first display mode, and when the height or age is lower than the predetermined threshold, the control unit 110 displays the call operation reception unit D in a second display mode, which is a display mode simpler than the first display mode. Therefore, for example, when the visitor W is a child, the call operation reception unit D is displayed in the second display mode, which is a simple display mode, thereby providing an aerial touch display 100 that is easy for children to operate.

In addition, according to the fourth embodiment of the intercom device 1, the second display mode includes at least one of a mode in which the number of operation buttons included in the call operation reception unit D is reduced and a mode in which the size of the operation buttons is increased compared to the first display mode. This makes it easy for even children to operate the aerial touch display 100.

Furthermore, according to the fourth embodiment of the intercom device 1, the attributes include whether the visitor W is a person associated with the apartment building M in which the collective entrance device 10B is installed. Then, if the visitor W is a person associated with the apartment building M, the control unit 110 displays the call operation reception unit F2 in a third display mode different from the first display mode, and if the visitor W is not a person associated with the apartment building M, the control unit 110 displays the call operation reception unit C2 in the first display mode. In this way, by adopting different display modes depending on whether the visitor W is, for example, a resident or not, it is possible to ensure security while improving operability.

Furthermore, according to the fourth embodiment of the intercom device 1, the first display mode is a display mode that includes at least the numeric keypad 41, and the third display mode is a display mode that includes at least the display of the room number 62 in the apartment building M to which the visitor W is associated. Therefore, when the visitor W is a resident, relative, friend, etc., a call button that allows the associated room number 62 to be directly called can be displayed in the aerial image G, greatly improving operability.

For example, when the control unit 110 determines that the visitor W is a foreigner based on the attribute information received from the camera 120, the control unit 110 may change the language notation of the call operation reception units C2, D, and F2 to a specified foreign language. According to this configuration, for example, when there is a high possibility that the visitor is a foreigner, the call operation reception units C2, D, and F2 can be displayed in English instead of Japanese, thereby improving the operability of the aerial touch display 100.

The present invention is not limited to the above-described embodiment, and can be modified, improved, etc. as appropriate. In addition, the material, shape, dimensions, values, form, number, location, etc. of each component in the above-described embodiment are arbitrary and not limited as long as they can achieve the present invention.
