Description

  The present invention is, for example, a pseudo window and a wall having a pseudo window provided on a wall of a room such as a central control room or a meeting room of a plant such as a factory or a power plant, which is highly closed or a room with a limited outdoor view. About.

  Conventionally, for example, in a central control room or a meeting room of a plant of a factory or a power plant, a window cannot be provided for the purpose of ensuring quietness or protecting against secret leakage, or a window cannot be physically provided. In a highly closed room such as a basement or a room with poor sunlight, a pseudo window is provided on the wall to prevent a psychological adverse effect on human beings in the room. In other words, by seeing the outdoor scenery image displayed in this simulated window, the human (experience person) in the room can make a simulated experience as if viewing the outdoor scenery through the actual window. This provides a sense of openness and comfort to people in highly closed rooms, and prevents psychological adverse effects such as reduced concentration, drowsiness, and lack of relaxation.

  As this type of pseudo window, there is one that is formed by pasting a film for forming a pseudo window depicting a window or a landscape on a wall surface as disclosed in Patent Document 1, for example. Further, as disclosed in, for example, Patent Document 2, a window frame portion constituting a peripheral portion is formed of a wooden frame or a metal frame, and a moving image (or still image) such as an outdoor landscape is formed in the opening portion of the window frame portion. There is a configuration in which a thin and flat image display device that displays an image is held. And in the pseudo window formed with the film for forming the pseudo window, since the indoor person sees a still image that does not change constantly, the discomfort tends to occur and the effect of giving a feeling of openness and comfort is low. In the pseudo window that can display a moving image with the device, a realistic (more realistic) landscape image is displayed, so that a great psychological effect can be obtained.

On the other hand, for example, as disclosed in Patent Document 3, a landscape photograph is incorporated into an assembly window frame, and an audio switch, an aroma switch, and a switch for several colors are provided in a part of the window outer frame into which the assembly window frame is fitted. Some of them are configured by arranging light emitters having the same. In this simulated window, the outdoor scenery will be displayed as a still image, but it will naturally be emitted by sound such as the release of fragrance from the forest bath, the chirping of a bird or the stream of a stream, and the color lighting that matches the scenery. A near realistic scene can be brought out, thereby making it possible to enhance the psychological effect on human beings in the room. Further, as shown in FIG. 3 of Patent Document 3, by providing a pseudo-window door, it is possible to make it closer to an actual window and enhance the psychological effect.

  However, in the pseudo window provided with the thin display device disclosed in Patent Document 2 above, it is possible to display an outdoor landscape or the like with a moving image. There was a problem that the effect could not be obtained.

  In addition to a real image, a voice switch (sound generator) or a pseudo window door provided in the pseudo window disclosed in Patent Document 3 is applied to the pseudo window disclosed in Patent Document 2, and the image is added to the image. Even in the case of letting indoor people experience the sound of a small bird swaying or the murmur of a brook, in the actual window, when the window door is opened, the outdoor sound propagates directly into the room and spreads. When the window is closed, a clear sound field leading to the sound is created in the room, and the sound from the outdoor field propagates through the window frame and the window door and propagates into the room. However, the problem is that the sound field that changes with the opening and closing of the window door cannot be reproduced and a sufficient sense of realism cannot be obtained because the sound field is simply formed inside the room. was there.

  In view of the above circumstances, the present invention has a pseudo window that can display an outdoor landscape in a realistic manner, and reproduce a change in sound caused by opening and closing of the pseudo window door, thereby providing a sense of realism, and the pseudo window. The purpose is to provide a wall.

The simulated window according to the present invention allows an indoor experience person to view an outdoor scenery image displayed on the image display device through an opening of a pseudo window frame provided on a wall, so that the actual outdoor scenery can be seen from the window. A pseudo window that makes a pseudo experience as if looking at, a pseudo window door that opens and closes an opening of the pseudo window frame, and a sound generator that artificially emits outdoor sound according to the outdoor landscape image; The sound generator is configured to propagate sound toward the back side of the wall with the pseudo window door closed, and to open the pseudo window door and directly propagate sound toward the room. Is attached to the pseudo-window door, and the pseudo-window door is simulated to reproduce the volume and tone of the sound propagating from the outdoors to the room, which varies depending on the difference in sound transmission loss depending on the actual opening and closing of the window door. Depending on whether the sound generator is open or closed And wherein varying the volume and timbre of the sound propagating in the chamber.

  In this invention, by changing the volume and tone of the sound propagating from the sound generator to the room according to the opening and closing of the pseudo window door, the actual outdoor due to the difference in sound transmission loss according to the actual opening and closing of the window door. Changes in sound volume and tone color can be simulated. That is, in an actual window, when the window door is closed, the sound transmission loss varies depending on the frequency of the outdoor sound when the outdoor sound passes through the window door. Therefore, the sound propagated into the room will change not only the volume but also the timbre, but in the present invention, not only the volume of the sound propagated into the room is changed according to the opening and closing of the pseudo window door, By changing the timbre according to the sound transmission loss of the actual window, it is possible to reliably reproduce the sound propagating into the room.

Furthermore , the sound emitted from the sound generator with the pseudo-window door closed is propagated toward the back side of the wall, so that the sound transmitted through the pseudo-window door from the back side of the wall propagates into the room. As a result, it is possible to propagate the sound whose sound volume and tone change according to the sound transmission loss due to the simulated window door to the room, so that the sound propagating from the outdoors with the actual window door closed to the room is simulated. Can be reproduced. Moreover, the sound generated from the sound generator is propagated in accordance with the outdoor landscape image displayed on the image display device directly to the indoors while opening the pseudo-window door, and a clear sound field that leads to the outdoor landscape image is generated. It can be formed indoors, and the state of opening the actual window can be reproduced.

In the wall having a pseudo window of the present invention, characterized by comprising the above-mentioned pseudo Nimado. Thereby, the wall provided with the effect of said pseudo window can be formed.

  According to the pseudo window and the wall having the pseudo window of the present invention, the outdoor scenery is displayed realistically by the image display device, and the change due to the opening and closing of the pseudo window door according to the outdoor scenery image is realistically reproduced. As a result, it is possible to surely give a sense of realism to people (experiencers) in a room with high closing performance. This makes it possible for a person in the room to experience a simulated experience as if looking at the outdoor scenery through the actual window, giving a sense of openness and comfort, reducing concentration, Psychological adverse effects such as drowsiness and lack of relaxation can be reliably prevented.

The opening 1a is opened (opened).

  Moreover, in the pseudo window door 2 of this embodiment, as shown in FIG. 4, the other vertical frame part 2f of each pseudo window door part 2a, 2b is the cross section extended up and down from the upper end side to the lower end side. A U-shaped sound insulation member 5 is provided. And this sound insulation member 5 is in the state which closed each pseudo window door part 2a, 2b so that the opening side may face the back side of inner wall B1, ie, outer wall B2 side (space B3 side between double walls B). Is provided. As shown in FIGS. 3 and 4, an elongated speaker (sound generating device) 6 extending vertically is accommodated in the internal space of the sound insulation member 5, and the pseudo window door portions 2 a and 2 b (pseudo window door 2). One speaker 6 is attached to each. A sound-insulating material such as a cloth material that closes the opening is attached to the opening side of the sound-insulating member 5 so that the speaker 6 accommodated in the internal space of the sound-insulating member 5 is not exposed to the outside. May be. Moreover, the sound insulation member 5 should just be formed with the material with high sound insulation, such as a metal, wood, a resin material, for example, and if it has desired sound insulation, it is not necessary to specifically limit the material.

  The support frame member 3 is formed in a rectangular cylinder shape, and as shown in FIGS. 1, 2, and 5 to 8, one end is fixed and supported on the inner peripheral edge forming the opening B4 of the inner wall B1. The opening B4 of the inner wall B1 and thus the opening 1a of the pseudo window frame 1 are provided so as to extend toward the outer wall B2. That is, the support frame member 3 is disposed in the space B3 between the double walls B (B1, B2) with one end connected to the inner wall B1.

  The image display device 4 is a thin image display device such as a liquid crystal display or a plasma display, for example, and as shown in FIGS. 1, 2, and 5 to 8, the display unit 4a is supported toward the room C side. It is attached to and supported by the other end of the frame member 3. At this time, when viewing the opening 1a of the pseudo window frame 1 from the room C side, the image display device 4 displays the outdoor landscape image displayed on the display 4a on the entire surface of the opening 1a. Is provided.

  The image display device 4 and the speaker 6 are connected to a playback device (not shown) such as a DVD player, and an outdoor landscape image played back by the playback device is displayed on the display unit 4a of the image display device 4 as a moving image. An image (or a still image) is displayed, and a sound (acoustic sound) such as a bird's tweet or a stream's murmur according to the outdoor landscape image is emitted from the speaker 6.

  Next, the operation and effect of the pseudo window A and the wall B having the pseudo window A will be described.

  In the present embodiment, as shown in FIGS. 1, 5 and 6, the outdoor landscape is reproduced by the playback device in a state where the pair of pseudo window door portions 2a and 2b are closed (the pseudo window door 2 is closed). When the image is reproduced, an outdoor landscape image is displayed on the display unit 4a of the image display device 4 (in the pseudo window A). Then, a person in the room C (experience person M shown in FIG. 6) sees the outdoor landscape image displayed on the display unit 4a of the image display device 4 through the glass 2d of the closed pseudo window doors 2a and 2b. By doing this, you will have a simulated experience as if you were looking at the outdoor scenery through an actual window.

  However, just looking at such outdoor landscape images gives a feeling of openness and comfort to the human M in the highly closed room C, and causes psychological adverse effects such as reduced concentration, drowsiness, and lack of relaxation. The effect to prevent is low.

  On the other hand, in the present embodiment, an outdoor landscape image is displayed on the image display device 4 and a sound (acoustic) K1 such as a singing of a bird or a stream of a brook according to the outdoor landscape image is output from the speaker 6. Be emitted. At this time, as shown in FIGS. 5 and 6, the speaker 6 is accommodated in the internal space of the sound insulation member 5 provided in the other vertical frame portion 2 f of the pair of pseudo window door portions 2 a and 2 b, and this sound insulation member 5. However, since the opening side is directed to the back side of the inner wall B1 with the pseudo window doors 2a and 2b closed, the sound K1 emitted from the speaker 6 propagates to the back side of the inner wall B1 to form a sound field. To do.

  The sound K1 generated from the speaker 6 in this way is generated inside the support frame member 3 (the image display device 4 and the pseudo window door portions 2a, 2b because the pair of pseudo window door portions 2a, 2b are closed). (Space between the pseudo window doors 2) is filled with the sound, and such a sound K1 is transmitted through the pseudo window door 2 and the pseudo window frame 1 and propagates into the room C. For this reason, the sound K2 propagating into the room C is transmitted through the pseudo-window door 2 to attenuate the sound pressure level corresponding to the sound transmission loss of the window door. The sound is propagated to the room C by changing the volume and tone color like the sound propagated to the room C. That is, in an actual window, since the sound transmission loss (attenuation of sound pressure level) when the outdoor sound passes through a closed window door differs depending on the sound frequency, The timbre also changes and propagates into the room C. On the other hand, in this embodiment, a sound field is formed on the back side of the inner wall B1 by the speaker 6, and the sound K1 emitted from the speaker 6 is transmitted through the pseudo window door 2 and propagates into the room C. The outdoor sound that propagates through the door and propagates into the room is simulated, and the sound K2 propagates into the room C. Therefore, a person in the room C (experience person M) who is viewing an outdoor landscape image displayed on the image display device 4 sings a small bird emitted from the speaker 6 or a stream of a brook in accordance with the outdoor landscape image. The sound K1 is heard as if it is an outdoor sound that can be heard when the actual window is closed, and a realistic (real) simulated experience is obtained.

  On the other hand, when the experience person M opens the pair of pseudo window doors 2a, 2b (pseudo window door 2), the pseudo window doors 2a, 2b are closed as shown in FIGS. Since the opening side of the sound insulation member 5 directed toward the back side of the inner wall B1 faces the room C side, the sound K1 emitted from the speaker 6 accommodated in the sound insulation member 5 is directly radiated and propagated into the room C. It will be. For this reason, the sound K1 emitted from the speaker 6 according to the outdoor landscape image displayed on the image display device 4 forms a clear sound field connected to the outdoor landscape image and spreads in the room C. M will have a simulated experience as if he had opened the window of an actual window. That is, the outdoor sound that can be heard when the actual window is opened is reproduced.

  Therefore, in the pseudo window A and the wall B having the same according to the present embodiment, not only the volume of the sound propagating into the room C is changed according to the opening / closing of the pseudo window door 2, but also the sound transmission loss of the window door. Thus, since the timbre can be changed as well, it is possible to reliably reproduce the sound propagating into the room C like an outdoor sound propagating into the room C through an actual window.

  At this time, the sound K1 emitted from the speaker 6 with the pseudo window door 2 closed is propagated toward the back side of the inner wall B1, and this sound K1 is transmitted through the pseudo window door 2 from the back side of the inner wall B1 to the room C. By propagating, the sound K2 whose volume and tone are changed according to the sound transmission loss of the pseudo window door 2 is propagated to the room C like the sound propagating from the outdoors to the room when the actual window door is closed. It becomes possible. Further, since the sound K1 corresponding to the outdoor landscape image displayed on the image display device 4 can be directly propagated toward the room C while opening the pseudo window door 2, a clear sound field that leads to the outdoor landscape image is obtained. Can be formed in the room C to reproduce the state in which the actual window is opened.

  Therefore, according to the pseudo window A and the wall B having the pseudo window A according to the present embodiment, an outdoor landscape image is realistically displayed by the image display device 4 and a sound pseudo window corresponding to the outdoor landscape image is displayed. Since the change due to the opening and closing of the door 2 can be realistically reproduced, it is possible to surely give a sense of realism to a person (experience person M) in the room C with high closing performance. As a result, compared with the conventional simulated window, the person M in the room C can be assured of a simulated experience as if looking at the outdoor scenery through the actual window, giving a sense of openness and peace of mind and concentration. Psychological adverse effects such as weakness, drowsiness and lack of relaxation can be reliably prevented.

  The first embodiment of the pseudo window and the wall having the pseudo window according to the present invention has been described above. However, the present invention is not limited to the first embodiment described above, and may be appropriately selected without departing from the spirit of the present invention. It can be changed. For example, in this embodiment, the wall B having the pseudo window A is a double wall, but the pseudo window A (the image display device 4 or the support frame member 3) is embedded in one wall, for example. Alternatively, as shown in FIG. 9 exemplifying the central control room, the pseudo window A according to the present invention may be provided in the partition wall B that partitions the indoor space.

  In the present embodiment, the pseudo window door 2 is constituted by a pair of pseudo window door portions 2a and 2b attached to the pseudo window frame 1 so as to be rotatable. The door only needs to be configured to include one or a plurality of pseudo window door portions, and the sound K1 emitted from the speaker (sound generator) 6 attached to the pseudo window doors 2a and 2b is closed to the wall. If it can be propagated to the room C side in an open state on the back side of B1, there is no need to limit the configuration. Furthermore, the pseudo window door portions 2a and 2b need to be configured to include a rectangular frame-shaped door body 2c and a glass 2d fitted to fill the opening on the inner peripheral side of the door body 2c. There is no.

  In the present embodiment, the speaker (sound generating device) 6 attached to the pseudo window door 2 is provided on the other vertical frame portion 2f of each of the pair of pseudo window door portions 2a and 2b. If the sound K1 emitted from the speaker 6 can be propagated to the back side of the wall B1 in the closed state and to the room C side in the opened state, for example, the speaker 6 may be provided. There is no need to limit the installation position.

  Furthermore, in this embodiment, a speaker (sound generator) 6 is accommodated in the internal space of the sound insulating member 5 having a U-shaped cross section, and directivity is imparted to the sound K1 emitted from the speaker 6. When 6 itself has directivity, the sound insulation member 5 is not necessarily provided. In addition to this, even when the sound insulating member 5 is used, it is not necessary to limit the shape to a U-shaped cross section.

  Next, a pseudo window and a wall having the pseudo window according to the second embodiment of the present invention will be described with reference to FIGS. This embodiment is similar to the first embodiment, for example, a pseudo-room provided on a wall of a living room where a highly closed room such as a central control room or a meeting room of a plant such as a factory or a power plant, or an outdoor view is limited. The present invention relates to a window and a wall having the window. Therefore, here, the same reference numerals are given to the components common to the first embodiment, and the detailed description thereof is omitted.

  As shown in FIG. 10, the pseudo window D of this embodiment includes a pseudo window frame 1, a pseudo window door 2 (2 a, 2 b), a support frame member 3, and an image display device 4, as in the first embodiment. Configured. The pseudo window D is provided by being incorporated in the inner wall B1 on the room C side of the double wall (inner wall B1 and outer wall B2) B arranged side by side with a gap.

  In the first embodiment, the speaker (sound generating device) 6 is attached to the pseudo window door 2. However, in the present embodiment, the pair of left and right speakers 10 are each a pair of the pseudo window frame 1. These vertical frame portions 1b are arranged on the outside and in the vicinity of the vertical frame portions 1b along the vertical frame portions 1b, and are fixedly installed in the inner wall B1. These speakers 10 are fixed so as to radiate and propagate sound toward the room C.

  In the present embodiment, the support frame member 3 is provided with a sensor 11 that detects the open / closed state of the pseudo window door 2 (open / closed state of each of the pseudo window door portions 2a and 2b).

  Furthermore, as shown in FIG. 11, a playback device 12 such as a DVD player is connected to the image display device 4 and the speaker 10. In this embodiment, the playback device 12 and the image display device 4 are connected by the image signal circuit 13 that sends the image signal of the outdoor landscape image played back by the playback device 12 to the image display device 4. An outdoor landscape image is displayed on the display unit 4 a of the image display device 4 based on the image signal sent to the display device 4 by the image signal circuit 13.

  On the other hand, the playback device 12 and the speaker 10 are connected by an acoustic signal circuit 14 that sends an acoustic signal corresponding to an outdoor landscape image reproduced by the playback device 12 to the speaker 10, and the acoustic signal circuit 14 is connected to the pseudo window door 2. The switch 15 that switches according to the open / closed state (that is, switches according to the detection result of the sensor 11 that detects the open / closed state of the simulated window door 2), the power amplifier 16, and the actual window with the simulated window door 2 closed. And a filter 17 having sound attenuation characteristics corresponding to sound transmission loss in a state where the door is closed. The acoustic signal circuit 14 includes a first acoustic signal circuit 14 a and a second acoustic signal circuit 14 b that are switched by the changeover switch 15. The first acoustic signal circuit 14 a is in the state in which the pseudo window door 2 is opened. Are connected to the speaker 10 and are configured to send an acoustic signal from the playback device 12 to the speaker 10 through the power amplifier 16.

  On the other hand, the second acoustic signal circuit 14b is a circuit that connects the playback device 12 and the speaker 10 in a state in which the pseudo window door 2 is closed, and processes the acoustic signal from the playback device 12 by the filter 17, that is, the actual window door. After the acoustic signal is processed by the filter 17 so as to change the volume and tone color of the sound emitted from the speaker 10 into the room C according to the acoustic transmission loss when the outdoor sound is transmitted through the An acoustic signal is formed to be sent to the speaker 10 through the power amplifier 16. Note that the filter 17 may be an analog filter or a digital filter.

  In the pseudo window D of the present embodiment configured as described above, an outdoor landscape image is displayed by the playback device 12 in a state where the pair of pseudo window door portions 2a and 2b are closed (the pseudo window door 2 is closed). When reproduced, an outdoor landscape image is displayed on the display unit 4a of the image display device 4 (in the pseudo window A). Then, a person M in the room C sees the outdoor landscape image displayed on the display unit 4a of the image display device 4 through the glass 2d of the closed pseudo window doors 2a and 2b. You will have a pseudo-experience like watching the outdoor scenery.

  At this time, the sensor 11 detects that the pair of pseudo window door portions 2a and 2b are closed. Based on the detection result of the sensor 11, the playback device 12 and the speaker 10 are connected to the acoustic signal by the changeover switch 15. The second acoustic signal circuit 14b of the circuit 14 is connected. For this reason, the acoustic signal output from the reproduction device 12 according to the outdoor landscape image reproduced by the reproduction device 12 is transmitted from the speaker 10 to the room according to the sound transmission loss when the outdoor sound is transmitted through the actual window door. It is processed by the filter 17 so as to change the volume and tone of the sound emitted to C.

  Thereby, the sound emitted from the speaker 10 based on the input acoustic signal and propagating into the room C changes the volume and tone color like the sound propagating from the outdoors to the room with the actual window door closed. Propagates to room C. Therefore, a person in the room C (experience person M) who is viewing an outdoor landscape image displayed on the image display device 4 sings a small bird emitted from the speaker 10 according to the outdoor landscape image or a stream of a stream. You will hear the sound as if it were an outdoor sound that can be heard when the actual window is closed, and you will have a realistic (real) simulated experience.

  On the other hand, when the experience person M opens the pair of pseudo window door portions 2a, 2b (pseudo window door 2), the changeover switch 15 is switched in response to the detection result of the sensor 11 that detects this, and the acoustic signal circuit 14 switches from the second acoustic signal circuit 14b to the first acoustic signal circuit 14a. The acoustic signal output from the playback device 12 is sent to the speaker 10 through the power amplifier 16 as it is without being processed by the filter 17. Thus, the sound emitted from the speaker 10 is radiated and propagated into the room C without adjusting the volume and tone color. For this reason, the sound emitted from the speaker 10 according to the outdoor landscape image displayed on the image display device 4 forms a clear sound field connected to the outdoor landscape image and spreads in the room C. Will have a simulated experience as if the actual window was opened. That is, the outdoor sound that can be heard when the actual window is opened is reproduced.

  Therefore, in the simulated window D and the wall B having the same according to the present embodiment, not only the volume of the sound propagated into the room C is changed according to the opening / closing of the simulated window door 2, but also the sound transmission loss of the actual window door. Since the timbre can also be changed according to the sound, the sound that propagates into the room C can be reliably reproduced like the outdoor sound that propagates into the room through the actual window.

  At this time, by processing the acoustic signal with the filter 17 in the state in which the pseudo window door 2 is closed, the sound whose sound volume and tone change according to the sound transmission loss in the state in which the actual window door is closed. Can be reproduced without fail, and the sound and tone without changing the actual window door can be reproduced without processing the acoustic signal with the filter 17 with the pseudo window door 2 opened, That is, since the volume and tone color of the sound propagating into the room C can be adjusted depending on the presence or absence of the processing by the filter 17, even when the speaker 10 is incorporated in the inner wall B1 and fixed so as to emit sound toward the room C, The sound can be reliably propagated into the room C by reproducing the state in which the actual window door is opened and closed.

  Further, since the attenuation characteristics of the filter 17 can be designed arbitrarily, the outdoor that transmits the desired window door regardless of the material such as the pseudo window door 2, that is, the sound transmission property of the pseudo window door 2. Can be easily reproduced.

  Therefore, according to the pseudo window D and the wall B having the pseudo window D of the present embodiment, an outdoor landscape image is realistically displayed by the image display device 4 and a sound pseudo window corresponding to the outdoor landscape image is displayed. Since the change due to the opening and closing of the door 2 can be realistically reproduced, it is possible to surely give a sense of realism to a person (experience person M) in the room C with high closing performance. As a result, compared with the conventional simulated window, the person M in the room C can be assured of a simulated experience as if looking at the outdoor scenery through the actual window, giving a sense of openness and peace of mind and concentration. Psychological adverse effects such as weakness, drowsiness and lack of relaxation can be reliably prevented.

  The second embodiment of the pseudo window according to the present invention has been described above, but the present invention is not limited to the second embodiment described above, and includes the modifications shown in the first embodiment. Changes can be made as appropriate without departing from the scope. For example, in the present embodiment, the speaker (sound generating device) 10 is arranged along the vertical frame portion 1b on the outside and in the vicinity of each of the pair of vertical frame portions 1b of the pseudo window frame 1, and is incorporated in the inner wall B1. However, the installation position of the speaker 10 is not particularly limited, and is provided at an arbitrary position on the wall B or between the wall B and the experience person M. Also good.

  In the present embodiment, the open / close state of the pseudo window door 2 (pseudo window door portions 2a, 2b) is detected by the sensor 11 provided on the support frame member 3, but the pseudo window door 2 (pseudo window door) is used. If the switching state of the acoustic signal circuit 14 can be reliably switched based on the detection result, the installation position and the configuration of the sensor 11 are particularly limited. There is no need.

  Furthermore, the pseudo window D of the present embodiment changes the directivity of the speaker by opening and closing the pseudo window door 2 (pseudo window door portions 2a and 2b) like the pseudo window A shown in the first embodiment, Therefore, the pseudo window door 2 does not need to be provided so as to be rotatable, and it is not necessary to provide a so-called inner opening pseudo window door 2. The opening 1a may be configured to open and close in a direction along B, and the configuration of the pseudo window door 2 is not particularly limited.
