[0012] (Embodiment) The following describes an aerial touch display device 1, a collective entrance system E1, an intercom system 100, a control method, and a program according to the embodiments, with reference to the drawings. However, the following embodiment is merely one of various embodiments of the present disclosure. The following embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, each figure described in the following embodiment is a schematic diagram, and the ratio of the size and thickness of each component in the figure does not necessarily reflect the actual dimensional ratio.

[0013] (overview) As shown in Fig. 1, the aerial touch display device 1 of this embodiment is configured to be able to communicate with a public entrance device 4 (lobby intercom). When a user operates an aerial image 7 (see Fig. 4) displayed by the aerial touch display device 1, the public entrance device 4 responds according to the operation.

[0014] The aerial touch display device 1 and the collective entrance device 4 are installed at the common entrance of an apartment building. The apartment building includes a plurality of dwelling units. A visitor (user) to the apartment building can talk to a resident of the dwelling unit using the aerial touch display device 1 and the collective entrance device 4. The visitor may be a resident of the dwelling unit or a person other than a resident of the dwelling unit.

[0015] The aerial touch display device 1 includes a display unit 11, an optical member 12, a detection unit 13, and a communication unit 22. The display unit 11 emits light for generating an aerial image 7 (see FIG. 4). The optical member 12 forms the aerial image 7 using the light emitted from the display unit 11. The detection unit 13 detects a user's operation input action on the aerial image 7. More specifically, the operation input action is an action of bringing a part of the user's body (such as a finger) close to a predetermined area of ​​the aerial image 7. The communication unit 22 transmits a communication signal to the collective entrance device 4 according to the detection result of the detection unit 13.

[0016] The aerial image 7 includes a first image 71 (see FIG. 7) and a second image 72 (see FIG. 8). The first image 71 includes an operation image 711 (see FIG. 7) that accepts an operation for causing the collective entrance device 4 to call a resident. The second image 72 is displayed during at least one of a period in which the first image 71 is displayed and a period in which the first image 71 is not displayed. The second image 72 presents information to the user.

[0017] According to this embodiment, the uses of the aerial touch display device 1 are expanded compared to the case where the aerial image 7 includes only the first image 71. Therefore, the convenience of the aerial touch display device 1 can be improved.

[0018] Moreover, the control method of the aerial touch display device 1 causes the computer system (of the controller 2) to execute the step of controlling the display unit 11 and the optical member 12 to display the aerial image 7 in space.

[0019] In addition, the control method of the aerial touch display device 1 can be embodied in a program. The program of this embodiment is a program for causing one or more processors of a computer system to execute the control method of the aerial touch display device 1. The program may be recorded in a non-transitory recording medium readable by the computer system.

[0020] (detail) (1) Overall structure As shown in FIG. 1, the collective entrance system E1 includes an aerial touch display device 1 and a collective entrance device 4.

[0023] (2) Collective entrance device 2, the collective entrance device 4 includes a housing 51, a panel 52, an embedded portion 53, and a display 54 (display portion). The housing 51, the panel 52, and the embedded portion 53 are fixed to each other.

[0024] (2.1) Housing and display The housing 51 houses or holds each component of the collective entrance device 4. That is, each component of the collective entrance device 4 is integrated in the housing 51. For example, a communication unit 42 and an operation unit 44, which will be described later, are integrated in the housing 51.

[0025] 2, the shape of the housing 51 is a rectangular plate. The housing 51 has one surface 510 (front surface) on which the operation unit 44 of the collective entrance device 4 and the like are arranged. The display 54 is fixed to the one surface 510 of the housing 51.

[0026] In this embodiment, of the two sides in the thickness direction of the housing 51, the side of one surface 510 is defined as the front, and the side opposite the one surface 510 is defined as the rear. Also, when viewed from the front, both sides in the longitudinal direction of the housing 51 are defined as the top and bottom, and both sides in the lateral direction of the housing 51 are defined as the left and right. However, these definitions are not intended to limit the direction in which the collective entrance device 4 is used. Also, the arrows representing the front and back, left and right, and up and down in FIG. 2 and the like are merely depicted for the purpose of explanation, and do not have any substance.

[0027] (2.2) Panel 2, panel 52 is shaped like a rectangular plate. Panel 52 has a rectangular window hole 520 in the center near the upper side. Window hole 520 is a hole for exposing one surface 510 of housing 51 to the outside.

[0028] A mounting bracket is disposed on the rear surface of the panel 52. The panel 52 is attached to the bracket by, for example, hooking and screwing. The bracket holds the housing 51. In this manner, the panel 52 is fixed to the housing 51 via the bracket.

[0029] (2.3) Embedded part As shown in Fig. 2, the embedded portion 53 has a rectangular parallelepiped shape. The embedded portion 53 is, for example, a hollow embedded box. The embedded portion 53 is attached to the metal fitting. The embedded portion 53 is attached to the metal fitting by, for example, screwing. The metal fitting holds the housing 51. In this way, the embedded portion 53 is fixed to the housing 51 via the metal fitting.

[0030] 4, the embedded portion 53 is embedded in a structural body such as a wall 81. This fixes the embedded portion 53 to the structural body. When the embedded portion 53 is embedded in the structural body, the housing 51 and the panel 52 are exposed to the outside of the structural body.

[0031] (2.4) Other configurations As shown in FIG. 1, the collective entrance device 4 includes a processing unit 41, a communication unit 42, a storage unit 43, an operation unit 44, a microphone 45, a speaker 46, and an imaging unit 47.

[0032] The collective entrance device 4 also includes a computer system having one or more processors and a memory. At least some of the functions of the collective entrance device 4 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunication line such as the Internet, or may be provided by recording it on a non-transitory recording medium (such as a memory card) that can be read by the computer system.

[0033] The processing unit 41 includes one or more processors of the computer system. The processing unit 41 executes a program to realize a predetermined function. The processing unit 41 controls the components of the collective entrance device 4 other than the processing unit 41.

[0034] The communication unit 42 includes a communication interface device. The collective entrance device 4 is capable of communicating with the aerial touch display device 1 and the multiple dwelling intercoms 6 via the communication unit 42.

[0035] The storage unit 43 is a storage device configured by a hard disk drive (HDD), a solid state drive (SSD), etc. The storage unit 43 has an area for storing information necessary for controlling the collective entrance device 4.

[0036] The operation unit 44 accepts operation inputs from the user. The operation unit 44 has, for example, a plurality of physical buttons 440 (see FIG. 2). The display 54 (see FIG. 2) updates the screen displayed in response to an operation on the operation unit 44. The operation unit 44 may have a touch panel or a touch panel display. Furthermore, the operation unit 44 having a touch panel or a touch panel display may also function as the display 54.

[0037] The microphone 45 converts the input sound into an electric signal. The speaker 46 outputs a sound based on the electric signal input to the collective entrance device 4 (the electric signal converted from the sound).

[0038] More specifically, the sound input to microphone 45 is output from dwelling unit intercom 6. Speaker 46 outputs the sound input to dwelling unit intercom 6. This allows a user who visits the apartment building to talk to a resident of the dwelling unit via collective entrance device 4 and dwelling unit intercom 6.

[0039] The imaging unit 47 captures an image of the vicinity and generates a captured image. The imaging unit 47 includes an imaging element. The imaging element is, for example, a two-dimensional image sensor such as a CCD (Charge Coupled Devices) image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) image sensor.

[0040] The captured image generated by the imaging unit 47 may be a still image or a moving image. The captured image may be a monochrome image or a color image.

[0041] 2, the imaging unit 47 is disposed, for example, on one surface 510 of the housing 51 of the collective entrance device 4. The imaging unit 47 may be provided independently of the housing 51. For example, the imaging unit 47 may be attached to a wall or ceiling near the housing 51.

[0042] (3) Air touch display device As shown in Fig. 3, the aerial touch display device 1 includes a housing 31. The housing 31 houses or holds each component of the aerial touch display device 1. That is, each component of the aerial touch display device 1 is integrated in the housing 31. For example, the display unit 11 (see Fig. 1), the optical member 12, the detection unit 13, the communication unit 22, and the controller 2 are integrated in the housing 31.

[0043] The shape of the housing 31 is a rectangular parallelepiped. When viewed from the front, the longitudinal direction of the housing 31 is along the left-right direction. When viewed from the front, the lateral direction of the housing 31 is along the up-down direction. The housing 31 has one surface 310 (front surface). The housing 31 includes a light-transmitting cover 311 provided on the one surface 310.

[0044] The housing 31 of the aerial touch display device 1 and the housing 51 of the public entrance device 4 are arranged side by side, for example, as shown in Fig. 4. Note that the positional relationship between the housing 31 and the housing 51 is not limited to the positional relationship shown in Fig. 4. The housing 31 and the housing 51 may be arranged side by side, for example, vertically.

[0045] As shown in FIG. 1, the aerial touch display device 1 further includes a display unit 11, an optical member 12, a detection unit 13, a notification unit 14, and a controller 2.

[0046] The display unit 11 includes a display that displays an image (a two-dimensional image).

[0047] Optical member 12 includes, for example, an optical plate that changes the direction of transmitted light. Light emitted from display unit 11 passes through the optical plate and forms an image at a predetermined position, thereby generating aerial image 7 (see FIG. 5). As shown in FIG. 5, aerial image 7 and the image displayed on display unit 11 are symmetrical with respect to the optical plate as a plane of symmetry.

[0048] The optical element 12 may further include one or more lenses, which allows the size of the aerial image 7 to be increased or decreased compared to when the optical element 12 does not include a lens.

[0049] Aerial image 7 is a two-dimensional image. An angular difference θ1 between a plane including aerial image 7 and optical member 12 is equal to an angular difference θ2 between optical member 12 and display unit 11.

[0050] Detection unit 13 includes, for example, an infrared sensor. Detection unit 13 is disposed so that the position where aerial image 7 is formed is included in the detection range. When a part of the user's body (such as a finger) enters the detection range, detection unit 13 detects infrared rays emitted from the part of the user's body. As a result, detection unit 13 detects the user's operation input action on aerial image 7. More specifically, detection unit 13 detects to which position in aerial image 7 a motion of bringing part of the user's body closer has been performed.

[0051] Display unit 11, optical member 12, and detection unit 13 are configured to be rotatable around first rotation axis X1. Display unit 11, optical member 12, and detection unit 13 rotate around first rotation axis X1 while maintaining their relative positions. That is, display unit 11 and optical member 12 rotate around first rotation axis X1 while maintaining angular differences θ1 and θ2. Therefore, when display unit 11 and optical member 12 rotate around first rotation axis X1 by a predetermined angle, aerial image 7 also rotates around first rotation axis X1 by a predetermined angle. Furthermore, detection unit 13 also rotates, so that the detection range of detection unit 13 follows the position of aerial image 7. FIG. 5 shows a state before display unit 11, optical member 12, and detection unit 13 rotate, and FIG. 6 shows a state after display unit 11, optical member 12, and detection unit 13 rotate. In addition, the display unit 11, the optical member 12 and the detection unit 13 can also be rotated from the position shown in FIG. 6 to the position shown in FIG.

[0052] Aerial image 7 includes a first image 71 (see FIG. 7) and a second image 72 (see FIG. 8). However, aerial image 7 including first image 71 and second image 72 means that there is an opportunity for first image 71 to be displayed in aerial image 7 and an opportunity for second image 72 to be displayed in aerial image 7, but does not necessarily mean that first image 71 and second image 72 are displayed at the same time. Therefore, there are cases where first image 71 is not displayed and second image 72 is displayed, and cases where first image 71 is displayed and second image 72 is not displayed.

[0053] The first image 71 includes an operation image 711 that accepts an operation for causing the collective entrance device 4 to call a resident. The second image 72 is displayed during at least one of a period during which the first image 71 is displayed and a period during which the first image 71 is not displayed. The second image 72 presents information to the user.

[0054] 4, aerial image 7 is formed in front of housing 31. More specifically, aerial image 7 is formed at a position covering at least a portion of cover 311 of housing 31. However, the position at which aerial image 7 is formed is not limited to this position.

[0055] Notification unit 14 (see FIG. 1) includes, for example, a speaker that emits sound (which may include voice). When controller 2 adjusts the tilt of aerial image 7, notification unit 14 notifies the user that the tilt is being adjusted.

[0056] As shown in FIG. 1, the controller 2 includes a processing unit 21, a communication unit 22, and a storage unit .

[0057] The controller 2 also includes a computer system having one or more processors and a memory. At least some of the functions of the controller 2 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunication line such as the Internet, or may be provided by recording it on a non-transitory recording medium (such as a memory card) that can be read by the computer system.

[0058] The processing unit 21 includes one or more processors of the computer system. The processing unit 21 executes a program to realize a predetermined function.

[0059] The processing unit 21 has a display switching unit 211 and an adjustment unit 212. Note that these merely indicate functions realized by the processing unit 21, and do not necessarily indicate actual configurations.

[0060] Display switching unit 211 switches the image displayed as aerial image 7. In this way, display switching unit 211 switches between displaying and hiding first image 71, and displaying and hiding second image 72.

[0061] More specifically, display switching unit 211 controls display unit 11. When an image corresponding to first image 71 is displayed on display unit 11, first image 71 is displayed in aerial image 7. When an image corresponding to first image 71 is not displayed on display unit 11, first image 71 is not displayed in aerial image 7. First image 71 is, for example, the same image as the image corresponding to first image 71, or an enlarged or reduced image of the image corresponding to first image 71.

[0062] When an image corresponding to second image 72 is displayed on display unit 11, second image 72 is displayed in aerial image 7. When an image corresponding to second image 72 is not displayed on display unit 11, second image 72 is not displayed in aerial image 7. Second image 72 is, for example, the same image as the image corresponding to second image 72, or an enlarged or reduced image of the image corresponding to second image 72.

[0063] Furthermore, display switching unit 211 switches the size of first image 71 and the size of second image 72. The size of first image 71 in aerial image 7 is proportional to the size of an image corresponding to first image 71 on display unit 11. The size of second image 72 in aerial image 7 is proportional to the size of an image corresponding to second image 72 on display unit 11. Display switching unit 211 switches the size of first image 71 and the size of second image 72 by controlling the image displayed on display unit 11.

[0064] Adjustment unit 212 adjusts the tilt of aerial image 7. More specifically, adjustment unit 212 adjusts the tilt of aerial image 7 by rotating display unit 11 and optical member 12 around first rotation axis X1. Adjustment unit 212 also rotates detection unit 13 together with display unit 11 and optical member 12 around first rotation axis X1.

[0065] In this embodiment, adjustment unit 212 rotates aerial image 7 around first rotation axis X1 along the horizontal direction. Thus, adjustment unit 212 can rotate aerial image 7 so that the user can easily view aerial image 7.

[0066] Adjustment unit 212 rotates aerial image 7 in response to an operation on operation unit 44 of public entrance device 4, for example.

[0067] The adjustment unit 212 can adjust the tilt of the aerial image 7 in multiple stages. The adjustment unit 212 can adjust the tilt of the aerial image 7 to multiple tilts including a first tilt and a second tilt. FIG. 6 shows the aerial touch display device 1 when the tilt of the aerial image 7 is the first tilt, and FIG. 5 shows the aerial touch display device 1 when the tilt of the aerial image 7 is the second tilt. When the tilt of the aerial image 7 is the first tilt, as shown in FIG. 6, a normal N1 extends from the aerial image 7 along the horizontal direction (front-back direction). When the tilt of the aerial image 7 is the second tilt, as shown in FIG. 6, a normal N2 extends diagonally upward from the aerial image 7.

[0068] The first inclination is, for example, an inclination when the normal line N1 forms an angle of 0 to 10° with respect to the horizontal plane. The second inclination is, for example, an inclination when the normal line N2 forms an angle of 40 to 50° with respect to the horizontal plane.

[0069] Moreover, the inclination of aerial image 7 can be expressed, for example, as the angle that aerial image 7 makes with respect to the horizontal plane. In this case, the first inclination is 80 to 90°, and the second inclination is 40 to 50°.

[0070] The communication unit 22 (see FIG. 1) of the controller 2 includes a communication interface device. The controller 2 is capable of communicating with the collective entrance device 4 via the communication unit 22. In this disclosure, "capable of communication" means that signals can be transmitted and received directly or indirectly via a network or a repeater, etc., by an appropriate communication method such as wired communication or wireless communication.

[0071] The storage unit 23 is a storage device configured by a hard disk drive (HDD), a solid state drive (SSD), etc. The storage unit 23 has an area for storing information necessary for controlling the aerial touch display device 1.

[0072] (4) Control device The control device 9 relays communications between the collective entrance system E1 and the multiple dwelling intercoms 6.

[0073] When a user visiting the apartment building operates the collective entrance device 4 or the aerial image 7 to call a resident of a residence, a first communication signal is transmitted from the collective entrance system E1 to the control device 9. The control device 9 transmits the first communication signal to the residence intercom 6 corresponding to the address included in the received first communication signal. Thereafter, when the resident performs a specified operation on the residence intercom 6, a second communication signal is transmitted from the residence intercom 6 to the control device 9. The control device 9 transmits the received second communication signal to the collective entrance system E1 and establishes communication between the collective entrance system E1 and the residence intercom 6. This enables the user to talk to the resident.

[0074] (5) Apartment intercom Each of the multiple dwelling intercoms 6 includes a processing unit 61 , a communication unit 62 , a memory unit 63 , an operation unit 64 , a microphone 65 , a speaker 66 , and a display unit 67 .

[0075] Each of the multiple dwelling intercoms 6 includes a computer system having one or more processors and a memory. At least some of the functions of the dwelling intercom 6 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded and provided on a non-transitory recording medium (such as a memory card) that can be read by the computer system.

[0076] The processing unit 61 includes one or more processors of the computer system. The processing unit 61 executes a program to realize a predetermined function. The processing unit 61 controls the components of the dwelling intercom 6 other than the processing unit 61.

[0077] The communication unit 62 includes a communication interface device. The dwelling intercom 6 is capable of communicating with the collective entrance system E1 via the communication unit 62.

[0078] The storage unit 63 is a storage device configured by a hard disk drive (HDD), a solid state drive (SSD), etc. The storage unit 63 has an area for storing information necessary for controlling the dwelling intercom 6.

[0079] The operation unit 64 receives operations from a user. The operation unit 64 has, for example, one or more physical buttons. The operation unit 64 may have a touch panel or a touch panel display.

[0080] The microphone 65 converts the input sound into an electrical signal. The speaker 66 outputs a sound based on the electrical signal input to the dwelling intercom 6 (the electrical signal converted from the sound).

[0081] The display unit 67 includes a display for displaying an image. The display unit 67 displays, for example, a captured image generated by the imaging unit 47 of the public entrance device 4.

[0082] (6) First Operation Example Next, a first operation example of intercom system 100 in the case where a user visiting an apartment building uses collective entrance system E1 will be described.

[0083] As shown in FIGS. 7 to 9, the aerial touch display device 1 switches between and displays a plurality of types of aerial images 7.

[0084] Fig. 7 shows an aerial image 7 for inputting a room number (apartment number). The aerial touch display device 1 may display the aerial image 7 of Fig. 7 when no operation is performed on the aerial image 7 for a predetermined period of time or more, or may display the aerial image 7 of Fig. 7 when a specific operation is performed on the operation unit 44 (physical button 440) of the collective entrance device 4. Alternatively, the aerial touch display device 1 may determine the presence or absence of a user near the collective entrance system E1 based on a captured image generated by the imaging unit 47 or a detection result of a human presence sensor, and display the aerial image 7 of Fig. 7 when a user is present near the collective entrance system E1.

[0085] In the aerial image 7 of FIG. 7, a first image 71 is displayed, and a second image 72 is not displayed.

[0086] Furthermore, in the aerial image 7 of FIG. 7, in addition to the first image 71, a third image 73 is displayed. The third image 73 includes a plurality of function keys that accept operations. Operations on the plurality of function keys are detected by the detection unit 13 (see FIG. 1). The collective entrance system E1 executes a predetermined function when an operation is performed on a function key. For example, when the leftmost function key is operated, the collective entrance system E1 switches the language displayed on the aerial image 7. Also, for example, when the second function key from the left is operated, the collective entrance system E1 executes a call to the manager's room.

[0087] 7 includes an operation image 711 for receiving an operation for making the collective entrance device 4 call a resident. The operation image 711 has a numeric keypad, an asterisk (*) key, an erase key, and a call key. An operation on the operation image 711 is detected by the detection unit 13 (see FIG. 1).

[0088] 7 further includes a display image 712 presenting information to assist in the operation of having the collective entrance device 4 call a resident. Display image 712 includes an image explaining how to use the aerial image 7 (text saying "Please enter the room number"), and an image showing the room number that has been entered (or is being entered) using operation image 711.

[0089] The user operates the aerial image 7 in FIG. 7 to input the room number of the residence to be visited. For example, if the user wishes to call the resident of room 201, the user presses the numeric keys to input the room number. The input room numbers are displayed in sequence as display image 712 each time the numeric keys are pressed. Finally, the user presses the call key to confirm the input of the room number.

[0090] An operation on the aerial image 7 is detected by the detection unit 13, and the detection result is notified to the collective entrance device 4. Therefore, when the input of a room number is confirmed by an operation on the aerial image 7, the collective entrance device 4 is notified of the input room number.

[0091] When the input of the room number is confirmed, the collective entrance device 4 transmits a first communication signal including information of the specified room number (address of the dwelling intercom 6) to the dwelling intercom 6 of the dwelling having the room number. More specifically, the collective entrance device 4 transmits the first communication signal to the dwelling intercom 6 via the control device 9. When the dwelling intercom 6 receives the first communication signal, it calls the resident, for example, by sound. When the resident performs a predetermined operation on the operation unit 64 of the dwelling intercom 6, the dwelling intercom 6 transmits a second communication signal to the collective entrance device 4 to establish communication for a call with the collective entrance device 4. More specifically, the dwelling intercom 6 transmits the second communication signal to the collective entrance device 4 via the control device 9. When communication for a call is established, the user who visits the collective residence can talk to the resident.

[0092] FIG. 8 shows the aerial image 7 displayed from when the input of the room number is confirmed until communication for a call is established between the dwelling intercom 6 and the collective entrance device 4. In the aerial image 7 of FIG. 8, the second image 72, the fourth image 74, and the fifth image 75 are displayed, and the first image 71 and the third image 73 are not displayed. The fourth image 74 includes text indicating that a call is being made and text indicating the room number of the called party. The fifth image 75 includes a stop key that accepts an operation to stop the call. An operation on the stop key is detected by the detection unit 13. When the stop key is operated, the intercom system 100 stops the call to the resident. The second image 72 presents, for example, information regarding a guide to the collective housing complex.

[0093] FIG. 9 shows the aerial image 7 displayed when communication for a call is established between the dwelling intercom 6 and the collective entrance device 4. In other words, FIG. 9 shows the aerial image 7 displayed when a user and a resident are on a call using the intercom system 100. In the aerial image 7 of FIG. 9, the second image 72, the sixth image 76, and the seventh image 77 are displayed, and the first image 71 and the like are not displayed. The sixth image 76 includes text indicating that a call is in progress and text indicating the room number of the caller. The seventh image 77 includes an end key that accepts an operation for ending the call. An operation on the end key is detected by the detection unit 13. When the end key is operated, the intercom system 100 disconnects the communication for the call between the dwelling intercom 6 and the collective entrance device 4. In addition, when a predetermined end operation is performed on the operation unit 64 of the dwelling intercom 6, the intercom system 100 also disconnects the communication for the call between the dwelling intercom 6 and the collective entrance device 4. Furthermore, when a predetermined unlocking operation is performed on the operation unit 64 of the dwelling intercom 6, the collective entrance system E1 unlocks the door to the shared entrance.

[0094] When the call communication between the dwelling intercom 6 and the collective entrance device 4 is disconnected, the aerial touch display device 1 switches the aerial image 7 to an initial screen (for example, the screen shown in FIG. 7).

[0095] As described above as the first operation example, the method of displaying aerial image 7 by controller 2 preferably includes at least one of displaying second image 72 during a period when first image 71 is not displayed, and displaying first image 71 during a period when second image 72 is not displayed. Figures 8 and 9 show aerial image 7 in which second image 72 is displayed during a period when first image 71 is not displayed. Figure 7 shows aerial image 7 in which first image 71 is displayed during a period when second image 72 is not displayed.

[0096] Furthermore, in the first operation example, when the detection unit 13 detects an action to call a resident as an operation input during a period in which the first image 71 is displayed and the second image 72 is not displayed, the controller 2 displays the second image 72. That is, when the user performs an action to call a resident with respect to the aerial image 7 in Fig. 7, the aerial image 7 in Fig. 8 displaying the second image 72 is formed. Furthermore, when the detection unit 13 detects the action to call, the controller 2 makes the first image 71 invisible and displays the second image 72, as shown in Fig. 8.

[0097] In the first operation example, when the collective entrance device 4 stops calling the resident and / or when the call based on the call to the resident (started with the call as a trigger) ends, the controller 2 displays the first image 71 as shown in Fig. 7. That is, when the fifth image 75 (cancel key) in Fig. 8 is operated to stop the call to the resident, when the seventh image 77 (end key) in Fig. 9 is operated to end the call, and when a predetermined end operation is performed on the operation unit 64 of the dwelling intercom 6 to end the call, the controller 2 displays the aerial image 7 in Fig. 7.

[0098] (7) Second operation example In the first operation example, a description has been given of the operation when a user operates aerial image 7, thereby causing intercom system 100 to establish communication for a call between dwelling intercom 6 and collective entrance device 4. Intercom system 100 performs the same operation as when the user operates aerial image 7, when the user operates operation unit 44 of collective entrance device 4.

[0099] That is, the user operates operation unit 44 to confirm the input of the room number. Next, collective entrance device 4 transmits a first communication signal including information of the specified room number to the dwelling intercom 6 of the dwelling corresponding to that room number. When the dwelling intercom 6 receives the first communication signal, it calls the resident, for example by sound. When the resident performs a specified operation on operation unit 64 of the dwelling intercom 6, the dwelling intercom 6 transmits a second communication signal to the collective entrance device 4 to establish communication for a call with the collective entrance device 4. This allows a call to be made between a user visiting the collective residence and the resident.

[0100] Controller 2 may switch the display of aerial image 7 in conjunction with an operation on operation unit 44. For example, when an operation is performed on operation unit 44 to confirm the input of a room number, controller 2 may display aerial image 7 of FIG.

[0101] (8) Contents of the second image The second image 72 is an image for presenting information unrelated to the resident's call and the telephone conversation based on the call.

[0102] The second image 72 may present, for example, information related to guidance of the apartment complex. The information related to guidance of the apartment complex may be, for example, information showing an evacuation route for the apartment complex, map information for the apartment complex, or information showing a route to a dwelling unit (call destination) corresponding to the room number input by the user.

[0103] The second image 72 may also include a notice for residents of the apartment complex, such as information about a meeting or event at the apartment complex, information about how to use the apartment complex's shared facilities, or a message from the manager.

[0104] The second image 72 may also present, for example, news, a weather forecast, disaster information, a warning against theft, or an election notice.

[0105] The second image 72 may also include, for example, an advertisement.

[0106] Second image 72 is an image solely for presenting information. However, second image 72 may also include an image for accepting a user's operation. For example, when only second image 72 is displayed in aerial image 7, if detection unit 13 detects an operation input to any area of ​​second image 72, first image 71 may be displayed in aerial image 7.

[0107] When an image other than second image 72 is displayed in aerial image 7, it is preferable that second image 72 does not accept any operations, and that the images other than second image 72 accept operations.

[0108] (9) Show / hide the first and second images (9.1) Received Signal The controller 2 determines a period for displaying the first image 71 and a period for displaying the second image 72 based on a reception signal received by the communication unit 22 from the collective entrance device 4. In other words, the controller 2 switches between displaying and hiding each of the first image 71 and the second image 72, triggered by receiving a reception signal. More specifically, the controller 2 controls the display unit 11 to switch between displaying and hiding each of the first image 71 and the second image 72.

[0109] For example, the controller 2 determines a period during which the first image 71 and a period during which the second image 72 are displayed in response to an operation on the operation unit 44 of the collective entrance device 4.

[0110] In addition, when the controller 2 receives a reception signal from the collective entrance device 4 notifying that communication for a call has been established between the collective entrance device 4 and the dwelling intercom 6, it switches from the aerial image 7 in Figure 8 to the aerial image 7 in Figure 9.

[0111] Also, for example, the controller 2 acquires from the collective entrance device 4 a received signal including a captured image generated by the imaging unit 47 or a detection result of a human presence sensor, and when it determines based on the received signal that a user is present near the collective entrance system E1, it displays the aerial image 7 of Figure 7.

[0112] (9.2) Image Information The collective entrance device 4 transmits image information to the controller 2 to be displayed as the second image 72. In other words, the signal transmitted from the collective entrance device 4 and received by the controller 2 includes image information to be displayed as the second image 72. The image information is, for example, image data of the second image 72.

[0113] (9.3) Size It is preferable that the controller 2 changes the size of at least one of the first image 71 and the second image 72. For example, the controller 2 may change the size of the at least one of the first image 71 and the second image 72 in response to an operation on the aerial image 7, or may change the size of the at least one of the first image 71 and the second image 72 based on a signal received by the communication unit 22 from the collective entrance device 4. The controller 2 may also change the size of the at least one of the first image 71 and the second image 72 in response to a voice operation.

[0114] Furthermore, the method of displaying aerial image 7 by controller 2 preferably includes matching at least a portion of the period during which first image 71 is displayed with at least a portion of the period during which second image 72 is displayed. In other words, controller 2 preferably has a function of displaying both first image 71 and second image 72.

[0115] When both the first image 71 and the second image 72 are displayed, the controller 2 preferably performs at least one of displaying the first image 71 larger than the second image 72 and displaying the first image 71 smaller than the second image 72. Furthermore, when both the first image 71 and the second image 72 are displayed, the controller 2 may display the first image 71 at the same size as the second image 72.

[0116] Figures 10 and 11 show a state in which aerial image 7 displays both first image 71 and second image 72. Aerial image 7 in Figure 10 may be displayed in place of aerial image 7 in Figure 7. Aerial image 7 in Figure 11 may be displayed in place of aerial image 7 in Figure 8.

[0117] In Fig. 10, the first image 71 is displayed larger than the second image 72. Moreover, the first image 71 in Fig. 10 is larger than the first image 71 in Fig. 11. Therefore, it is easy for the user to operate the first image 71.

[0118] When the user operates the first image 71 in Fig. 10 and confirms the input of the room number, the aerial image 7 in Fig. 11 is displayed. In Fig. 11, a fourth image 74 and a fifth image 75 are newly displayed. In Fig. 11, the second image 72 is displayed larger than the first image 71. Furthermore, the second image 72 in Fig. 11 is larger than the second image 72 in Fig. 10. Therefore, the user can easily obtain information from the second image 72.

[0119] (Modification) Modifications of the embodiment are listed below. The following modifications may be implemented in appropriate combination. In the following, the configuration of the above-described embodiment is referred to as a basic example. The same reference numerals are used to designate the same configuration as the basic example, and the description thereof is omitted.

[0120] (Variation 1) An intercom system 100 according to the first modification will be described with reference to FIGS.

[0121] In this first modification, display unit 11, optical member 12, and detection unit 13 are configured to be rotatable around second rotation axis X2 along the vertical direction (up-down direction). Display unit 11, optical member 12, and detection unit 13 rotate around second rotation axis X2 while maintaining their relative positions. Therefore, when display unit 11 and optical member 12 rotate around second rotation axis X2 by a predetermined angle, aerial image 7 also rotates around second rotation axis X2 by a predetermined angle. Furthermore, detection unit 13 also rotates, so that the detection range of detection unit 13 follows the position of aerial image 7. FIG. 12 shows a state before display unit 11, optical member 12, and detection unit 13 rotate, and FIG. 13 shows a state after display unit 11, optical member 12, and detection unit 13 rotate. Moreover, display unit 11, optical member 12, and detection unit 13 can also rotate from the position in FIG. 13 to the position in FIG. 12.

[0122] Controller 2 rotates display unit 11 and optical member 12 around second rotation axis X2, thereby rotating aerial image 7 around second rotation axis X2. Thus, controller 2 can rotate aerial image 7 so that the user can easily view aerial image 7.

[0123] Controller 2 rotates aerial image 7 in response to an operation on operation unit 44 of public entrance device 4, for example.

[0124] Aerial image 7 may be rotatable about second axis of rotation X2 and also about first axis of rotation X1 (see FIG. 5).

[0125] (Variation 2) An intercom system 100 according to the second modification will be described with reference to FIG. 1, FIG. 4, etc.

[0126] In this modification, controller 2 adjusts the tilt of aerial image 7 based on a reception signal received by communication unit 22 from collective entrance device 4. For example, collective entrance device 4 transmits a reception signal including a command to adjust the tilt of aerial image 7 to controller 2 in response to an operation on operation unit 44.

[0127] Here, the received signal may include face position information. The face position information is information based on the position of a person's face imaged by imaging unit 47 of public entrance device 4. Then, controller 2 may adjust the inclination of aerial image 7 based on the face position information.

[0128] When a user U1 (see FIG. 4) moves in front of the housing 31 of the collective entrance device 4 or the housing 51 of the aerial touch display device 1 to operate the collective entrance system E1, the imaging unit 47 captures an image of the user U1 and generates a captured image. The processing unit 41 of the collective entrance device 4 identifies the position of the face of the user U1 based on the captured image using face recognition technology. The processing unit 41 generates face position information. The face position information includes, for example, information indicating a height H1 from the floor surface 82 to the position of the face of the user U1. That is, the processing unit 41 estimates the height H1 based on the captured image. It is more preferable that the height H1 is the height from the floor surface 82 to the position of the eyes of the user U1.

[0129] Controller 2 adjusts the inclination of aerial image 7 according to height H1 (to match height H1). For example, memory unit 23 of controller 2 stores a predetermined threshold. If height H1 is equal to or greater than the threshold, controller 2 sets the inclination of aerial image 7 with respect to the horizontal plane to a second inclination (e.g., 40 to 50°) as shown in FIG. 5. If height H1 is less than the threshold, controller 2 sets the inclination of aerial image 7 with respect to the horizontal plane to a first inclination (e.g., 80 to 90°) as shown in FIG. 6. This allows the user to view aerial image 7 from a direction close to the front of aerial image 7, making it easier for the user to view and operate aerial image 7.

[0130] Controller 2 may adjust the tilt of aerial image 7 in three or more stages according to the position of the face of user U1. Furthermore, controller 2 may continuously adjust the tilt of aerial image 7 according to the position of the face of user U1.

[0131] Of the multiple adjustable tilts, controller 2 may adjust the tilt to the tilt at which a line connecting the position of user U1's face and the center of aerial image 7 intersects with aerial image 7 at an angle closest to 90 degrees.

[0132] (Variation 3) An intercom system 100 according to the third modification will be described with reference to FIG.

[0133] In this modification, controller 2 switches between displaying and not displaying aerial image 7 based on the result of authentication of the face of a person captured by imaging unit 47 of public entrance device 4.

[0134] The face authentication may be performed by the common entrance device 4 or by the controller 2. In the following, it is assumed that the common entrance device 4 performs the face authentication.

[0135] The storage unit 43 stores information on one or more people's faces. The processing unit 41 performs authentication by comparing the person's face captured by the imaging unit 47 with the information on the person's faces stored in the storage unit 43. If the matching rate between the person's face captured by the imaging unit 47 and any of the information on the person's faces stored in the storage unit 43 is equal to or higher than a certain level, the processing unit 41 outputs an authentication result indicating that the authentication has been successful. When the controller 2 obtains the authentication result indicating that the authentication has been successful from the processing unit 41, it causes the aerial image 7 to be displayed.

[0136] Processing unit 41 outputs an authentication result indicating that authentication has failed if the matching rate between the human face captured by imaging unit 47 and each of the information on one or more human faces stored in storage unit 43 is less than a certain level. When controller 2 obtains an authentication result indicating that authentication has failed from processing unit 41, controller 2 makes aerial image 7 invisible.

[0137] In this manner, in this modification, the use of aerial image 7 can be permitted only to persons who have been registered in advance.

[0138] (Variation 4) An intercom system 100 according to the fourth modification will be described with reference to FIG. 1, FIG. 4, etc.

[0139] In this modification, controller 2 displays aerial image 7 near floor surface 82 and parallel to floor surface 82. This allows the user to operate aerial image 7 with their feet. In other words, when the user moves their foot close to a predetermined area of ​​aerial image 7, detection unit 13 detects this movement, and in response, collective entrance system E1 makes a predetermined response.

[0140] (Variation 5) An intercom system 100 according to the fifth modification will be described with reference to FIG.

[0141] Controller 2 adjusts the position of aerial image 7 independently of adjusting the tilt of aerial image 7. In addition, controller 2 causes the detection range of detection unit 13 to follow the position of aerial image 7.

[0142] For example, the controller 2 may form an aerial image 7 at a first position, while at a different time, forming an aerial image 7 at a second position different from the first position. The first position is, for example, near the floor surface 82. The second position is, for example, near the housing 31. Furthermore, the controller 2 may form a plurality of aerial images 7 at a plurality of positions simultaneously.

[0143] The controller 2 adjusts the position of the aerial image 7 by controlling at least one of the display unit 11 and the optical member 12. For example, the controller 2 adjusts the position of the aerial image 7 by controlling the positional relationship between the display unit 11 and the optical member 12. Furthermore, for example, when the optical member 12 includes one or more lenses, the controller 2 adjusts the position of the aerial image 7 by adjusting the positions of the one or more lenses. Furthermore, for example, when the optical member 12 includes one or more mirrors, the controller 2 adjusts the position of the aerial image 7 by adjusting the position and orientation of the one or more mirrors.

[0144] (Variation 6) An intercom system 100 according to the sixth modification will be described with reference to FIG.

[0145] In this modification, the controller 2 adjusts at least one of the inclination of the first image 71 and the inclination of the second image 72 independently of the other. In the following, a case where the controller 2 adjusts the inclination of the first image 71 and the inclination of the second image 72 will be described.

[0146] The aerial touch display device 1 includes a display unit 11 (hereinafter referred to as the first display unit) that displays an image corresponding to a first image 71, and a display unit 11 (hereinafter referred to as the second display unit) that displays an image corresponding to a second image 72. The aerial touch display device 1 also includes an optical member 12 (hereinafter referred to as the first optical member) that forms an aerial image 7 (hereinafter referred to as the first aerial image) using light emitted from the first display unit, and an optical member 12 (hereinafter referred to as the second optical member) that forms an aerial image 7 (hereinafter referred to as the second aerial image) using light emitted from the second display unit.

[0147] The controller 2 controls the first display unit and the first optical member to form a first aerial image including a first image 71. The controller 2 also controls the second display unit and the second optical member to form a second aerial image including a second image 72.

[0148] Controller 2 then adjusts the tilt of the first aerial image by controlling the first display unit and the first optical member, and controller 2 adjusts the tilt of the second aerial image by controlling the second display unit and the second optical member.

[0149] The user can adjust the inclination of first image 71 and the inclination of second image 72 so that first image 71 and second image 72 are each easy to view.

[0150] Furthermore, the controller 2 may change at least one of the size of the first aerial image and the size of the second aerial image independently of the other. For example, when the first optical member includes one or more lenses, the controller 2 changes the size of the first aerial image by adjusting the positions of the one or more lenses. For example, when the second optical member includes one or more lenses, the controller 2 changes the size of the second aerial image by adjusting the positions of the one or more lenses.

[0151] (Variation 7) An intercom system 100 according to the seventh modification will be described with reference to FIG.

[0152] In the basic example, a light-transmitting cover 311 (see FIG. 5) is provided on the front surface (one surface 310) of housing 31, and aerial image 7 is formed in front of cover 311. In contrast, in this modification, as shown in FIG. 14, cover 311 is provided on top surface 312 of housing 31, and aerial image 7 is formed above cover 311.

[0153] In this way, the position at which aerial image 7 is formed is not limited to the front of housing 31, and may be, for example, above or diagonally above housing 31. Furthermore, housing 31 may have an oblique surface, and aerial image 7 may be formed at a position opposite to that surface (diagonally above that surface).

[0154] (Variation 8) An intercom system 100 according to the eighth modification will be described with reference to FIG.

[0155] In the basic example, the collective entrance device 4 is provided separately from the aerial touch display device 1. That is, in the basic example, the housing 31 of the aerial touch display device 1 is provided separately from the housing 51 of the collective entrance device 4. In contrast, in this modified example, the configuration of the aerial touch display device 1 is integrated in the housing 51A of the collective entrance device 4. This will be described in more detail below.

[0156] In this modified example, the collective entrance device 4 does not include a display 54 (see FIG. 4). A housing 51A of this modified example includes a light-transmitting cover 311 at the location where the display 54 was located in the basic example. The other configurations of the housing 51A are the same as those of the housing 51 of the basic example.

[0157] The display unit 11 (see FIG. 5) and the optical member 12 are arranged behind the cover 311. The aerial touch display device 1 extracts light emitted from the display unit 11 to the outside of the housing 51A through the cover 311, and forms an aerial image 7 outside the housing 51A.

[0158] 15, aerial image 7 is formed in front of housing 51A. More specifically, aerial image 7 is formed at a position covering at least a portion of cover 311 of housing 51. Aerial image 7 is also formed above operation unit 44 of collective entrance device 4. Aerial image 7 is also formed below imaging unit 47 of collective entrance device 4. However, the position at which aerial image 7 is formed is not limited to these positions.

[0159] According to this modification, the number of components of the collective entrance system E1 can be reduced, and the installation space of the collective entrance system E1 can also be reduced.

[0160] (Other variations) Other variations of the embodiment are listed below. The following variations may be implemented in appropriate combination. The following variations may also be implemented in appropriate combination with the above-mentioned variations.

[0161] Controller 2 in the basic example controls the tilt of aerial image 7 by controlling display unit 11 and optical member 12. In contrast, controller 2 may control the tilt of aerial image 7 by controlling at least one of display unit 11 and optical member 12.

[0162] The controller 2 of the basic example controls the display unit 11 to switch between display and non-display of each of the first image 71 and the second image 72. More specifically, the controller 2 controls an image displayed on the display unit 11 to switch between display and non-display of each of the first image 71 and the second image 72. In contrast, the controller 2 may control at least one of the display unit 11 and the optical member 12 to switch between display and non-display of each of the first image 71 and the second image 72. For example, the controller 2 may display the first image 71 and hide the second image 72 in the aerial image 7 by controlling the optical member 12 so that, among the images displayed on the display unit 11, an image corresponding to the first image 71 is formed by the optical member 12 and an image corresponding to the second image 72 is not formed by the optical member 12. Conversely, the controller 2 may control the optical element 12 so that an image corresponding to the second image 72 is formed by the optical element 12 among the images displayed on the display unit 11, and an image corresponding to the first image 71 is not formed by the optical element 12, thereby displaying the second image 72 in the aerial image 7 and not displaying the first image 71.

[0163] When aerial image 7 is formed, controller 2 may change the positional relationship between display unit 11 and optical member 12 to put aerial image 7 in an unformed state. For example, controller 2 may move optical member 12 to a position off the optical path of light emitted from display unit 11 to put aerial image 7 in an unformed state.

[0164] Controller 2 in the basic example adjusts the tilt of aerial image 7 in response to an operation on operation unit 44 of collective entrance device 4. In contrast to this, controller 2 may adjust the tilt of aerial image 7 in response to an operation on aerial image 7. Furthermore, controller 2 may adjust the tilt of aerial image 7 in response to a voice operation.

[0165] In the basic example, the tilt of aerial image 7 is adjustable in two stages. Alternatively, the tilt of aerial image 7 may be adjustable in multiple stages, such as three or more stages. Furthermore, the tilt of aerial image 7 may be continuously adjustable.

[0166] The tilt of aerial image 7 may be adjustable in three or more stages in response to an operation on operation unit 44 of collective entrance device 4. Furthermore, the tilt of aerial image 7 may be continuously adjustable in response to an operation on operation unit 44 of collective entrance device 4.

[0167] Setting information specifying the inclination of aerial image 7 during the period from when the aerial image 7 changes from a non-formed state to a formed state until the user performs an operation to change the inclination of the aerial image 7 may be stored in storage unit 23. The setting information is, for example, input to aerial touch display device 1 by an installer when installing aerial touch display device 1, and stored in storage unit 23. The aerial touch display device 1 adjusts the inclination of aerial image 7 according to the setting information read from storage unit 23.

[0168] The notification unit 14 in the basic example notifies by sound. In contrast, the notification unit 14 may be configured to notify visually. For example, the notification unit 14 may notify by emitting light or by displaying an image.

[0169] It is not essential that collective entrance device 4 is equipped with operation unit 44. Therefore, as an operation for collective entrance system E1, only an operation for the aerial image 7 may be possible.

[0170] The numbers on the numeric keypad of operation image 711 of first image 71 may be randomly arranged. In other words, the numeric keypad of operation image 711 may be a so-called magical numeric keypad. For example, each time first image 71 is newly displayed, the numbers on the numeric keypad may be randomly arranged.

[0171] The aerial touch display device 1 may further include a sound generating unit that generates an operation sound when the detection unit 13 detects an operation input action of the user on the aerial image 7.

[0172] When detection unit 13 detects a user's operation input action on aerial image 7, operation unit 44 of collective entrance device 4 may emit light.

[0173] Based on the identification result of the person's face captured by the imaging unit 47 of the collective entrance device 4, one or more room number candidates may be displayed on the aerial image 7. For example, the collective entrance system E1 identifies individuals by their faces and creates a record of which room numbers each person has entered in the past. Thereafter, when that person returns, the collective entrance system E1 determines, based on the record, which room number the person captured by the imaging unit 47 is likely to enter, and displays the corresponding one or more room numbers on the aerial image 7.

[0174] The size of the buttons (such as a numeric keypad) on the aerial image 7 may be changed based on the identification result of the face of the person imaged by the imaging unit 47 of the collective entrance device 4. For example, the collective entrance system E1 may estimate the age of the user (visitor) from the face, and change the size of the buttons on the aerial image 7 according to the age.

[0175] The language to be displayed on the aerial image 7 may be determined based on the identification result of the face of the person captured by the imaging unit 47 of the collective entrance device 4. For example, the collective entrance system E1 may estimate the nationality of the user (visitor) from the face, and determine the language to be displayed on the aerial image 7 according to the nationality.

[0176] The language to be displayed on the aerial image 7 may be determined based on the voice (language) input to the microphone 45. For example, the collective entrance system E1 may estimate the nationality of the user (visitor) from the voice, and determine the language to be displayed on the aerial image 7 according to the nationality.

[0177] When a predetermined password is entered into the aerial image 7, the collective entrance system E1 may unlock the door to the shared entrance.

[0178] In this disclosure, "equal" is not limited to a completely equal state, but also includes a difference within a range that does not cause practical problems. For example, if the difference between two values ​​is within a range of less than 5% of either value, it may be considered to be "equal" and the present disclosure may be applied.

The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The integrated circuits such as IC or LSI referred to here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of an LSI, or a logic device that allows reconfiguration of the connection relationship within the LSI or reconfiguration of the circuit partition within the LSI, can also be employed as a processor. The electronic circuits may be integrated into one chip, or may be distributed among multiple chips. The chips may be integrated into one device, or may be distributed among multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Thus, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0180] In addition, it is not essential that the multiple functions of the aerial touch display device 1 are integrated into one housing, and multiple components of the aerial touch display device 1 may be distributed across multiple housings. Furthermore, at least some of the functions of the intercom system 100 may be realized by a server or a cloud (cloud computing), etc.

[0181] Conversely, in the embodiment, at least some of the functions of the intercom system 100 that are distributed among multiple housings may be consolidated into one housing.
