By the way, the devices described in Patent Documents 1 and 2 do not have a means for controlling the position of floating objects in the performance space, and are limited to tracking floating objects that move freely in the space. It was something. SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to provide a system for controlling the floating state of floating objects in a performance space.

A first aspect of the present invention relates to an effect system for making floating objects float in the air. In the specification of the present application, the term "floating matter" refers to a tangible object having a certain rigidity that floats in the air on an air current. Examples of floating objects are balls, balloons, cotton, and feathers, and their shape is not particularly limited. For example, floating objects are not limited to spheres, and may be polyhedrons. Devices that can autonomously float on air currents, such as self-flying drones, are also included in floating objects. On the other hand, intangible objects, such as gases, mists, bubbles, etc., and objects that disappear on contact with other objects are excluded from the suspended matter referred to herein. A production system according to the present invention includes a plurality of exhaust devices. The plurality of exhaust devices are configured to generate clockwise or counterclockwise airflow in plan view in the performance space surrounded by the exhaust ports. The number of exhaust devices may be 2 or more, preferably 3 or more, or 4 or more, and may be 5 or more. For example, when the number of exhaust devices is two, by arranging the exhaust ports so that the air discharged from each exhaust port passes each other, a whirlpool air current can be generated in the presentation space. In addition, for example, when the number of exhaust devices is four, the exhaust ports of the exhaust devices are arranged at the four corners of the production space, and the air is discharged from each exhaust port in a clockwise or counterclockwise direction to create a vortex in the production space. of airflow can be generated. As a result, the production system according to the present invention can float the floating object by the air current in the production space.

Preferably, in the system according to the invention, the float is constructed such that the gas is contained by a flexible outer membrane. Examples of floats are balls and balloons. Moreover, it is also possible to mount a lighting device such as an LED and a speaker inside the floating object, like the ball disclosed in Patent Document 1 and Patent Document 2.

The system according to the invention further comprises an intake device. The air intake device itself or its air intake port is provided so as to suck the air discharged by the exhaust device above the performance space. Thus, by providing an intake device above the performance space, a tornado-like updraft can be generated in the performance space. This makes it easier to maintain the floating state of the floating matter.

Preferably, the system according to the invention further comprises a sensor and a controller. The sensor is for detecting the position of the floating object in the production space. The control device controls the air volume or wind speed by the exhaust device and/or the air intake device based on the detection information of the sensor. In this way, by feedback-controlling the exhaust device and the intake device using the information detected by the sensor, it becomes easier to keep the floating object at a predetermined position (for example, the center of the presentation space) in the presentation space. In addition, when the floating matter leaves a predetermined position in the presentation space, the floating matter can be returned to the predetermined position in the presentation space by feedback-controlling the exhaust device and the intake device. In addition, in the control of the exhaust device and the intake device, it is possible to control the air volume or wind speed by setting specific conditions and thresholds for the position of the floating object, or known machine learning such as deep learning and reinforcement learning Algorithms can also be used.

A second aspect of the present invention is a production method for floating objects in the air. A rendering method according to the present invention includes a step of exhausting air using a plurality of exhaust devices so as to generate clockwise or counterclockwise airflow in plan view in a rendering space surrounded by the exhaust ports of the plurality of exhaust devices. and a step of floating the floating object in the performance space by the airflow.

ADVANTAGE OF THE INVENTION According to this invention, the system and method for controlling the floating state of the floating object in performance space can be provided.

FIG. 1 is a perspective view schematically showing an example of arrangement of devices and floating objects (balls) that constitute a production system. FIG. 2 is a block diagram showing an example of each device that constitutes the production system. FIG. 3 is a flowchart showing an example of control processing by the control device.

EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated using drawing. The present invention is not limited to the embodiments described below, and includes appropriate modifications within the scope obvious to those skilled in the art from the following embodiments.

FIG. 1 is a perspective view showing an outline of an effect system 100 for causing floating objects F to float. FIG. 2 is a block diagram showing various devices that make up the production system 100. As shown in FIG. As shown in FIG. 1, in this embodiment, the floating object F is assumed to be a ball. In the illustrated example, there is only one floating object F (ball), but in this system it is also possible to float multiple balls at the same time. Also, the production system according to the present invention can handle various floating objects other than balls.

The production system 100 according to the present invention basically maintains a floating object F floating at a predetermined height in the air or moves the floating object F up and down in a production space provided indoors. It is intended for When the floating object F is touched by a spectator or the like, the impact causes it to move in the performance space. According to the production system 100, the moving floating object F is controlled to return to the vicinity of the center of the performance space. can also The production system 100 uses a plurality of exhaust devices 10 and intake devices 20 to generate an airflow in a production space surrounded by the exhaust ports of these exhaust devices 10. - 特許庁By controlling this airflow, the floating object F is made to float within the presentation space. In this embodiment, four exhaust devices 10 (a) to (d) are provided to define one performance space, but the number of exhaust devices 10 per one performance space is limited to this. It is also possible to use 2 to 10 units, for example. Also, in order to prevent air currents other than air currents from the plurality of exhaust devices 10 and intake devices 20 provided in the presentation system 100 from flowing into the presentation space, air currents in the space are blocked by walls, partitions (not shown), air showers, or the like. preferably restricted. Also, the performance space has a volume (width, depth, and height) that allows people to enter. For example, it is preferable that the width, depth, and height of the production space are each at least 2 m to 5 m or more, and it is possible to secure a larger volume.

As shown in FIG. 1, in the present embodiment, it is assumed that the production space has a planar rectangular shape (particularly, a planar square shape). Also, a plurality of air pillars 11, which are pillars for exhaust, are erected at the four corners of this performance space. The four air pillars 11(a)-(d) are provided with a plurality of exhaust ports 12(a)-(d) and are connected to exhaust devices 10(a)-(d), respectively. As a result, the air sent out from the plurality of exhaust devices 10 passes through the interior of the air pillar 11 and is exhausted from the exhaust port 12 provided on the side surface of the air pillar 11 . As shown in FIG. 1, the four air outlets 12 (a) to (d) provided in each of the four air pillars 11 generate clockwise or clockwise vortex-shaped air currents in the production space in a plan view. The direction in which the air is discharged from each of the exhaust ports 12(a) to (d) is set so as to Specifically, in the example shown in FIG. 1, the first exhaust port 12(a) discharges air in a direction toward the second exhaust port 11(b), and the second exhaust port 12(b) ) discharges air in the direction toward the third outlet 12(c), the third discharge port 12(c) discharges air in the direction toward the fourth outlet 12(d), and the fourth outlet 12(c) discharges air in the direction toward the fourth outlet 12(d). outlet 12(d) discharges air in a direction toward the first outlet 12(a). It is of course possible to set the discharge direction of each of the exhaust ports 12(a) to (d) in the direction opposite to the direction shown in FIG. By setting the exhaust direction of each of the exhaust ports 12(a) to (d) in this way, a vortex-shaped air current is generated in the production space. In this embodiment, four exhaust devices 10 and four air pillars 11 are provided, but the numbers can be increased or decreased according to the installation environment.

In addition, in the embodiment shown in FIG. 1, an intake device 20 for sucking air discharged from each exhaust port 12 is provided above the vicinity of the center of the performance space. In this embodiment, a propeller-shaped air intake device 20 (ceiling fan) is provided above the performance space, but the main body of the air intake device 20 is provided at another location, and the air intake device 20 is connected to the air intake device 20. The mouth may be provided above the performance space. In this embodiment, the intake device 20 is provided near the ceiling of the performance space, and the height from the floor surface to the intake device 20 may be 2 to 10 m, for example. In the intake device 20, the exhaust port 12 is also set at a position higher than 1 to 2 m. Thus, when the air discharged from each exhaust port 12 is sucked by the intake port 2, a tornado-like rising air current can be generated in the performance space surrounded by each exhaust port 12.例文帳に追加

Further, in the present embodiment, each of the exhaust devices 10(a) to (d) and the intake device 20 can independently control the air volume and wind speed. For example, the exhaust volume of the plurality of exhaust devices 10 as a whole can be made equal to the intake volume of the intake device 20, or the exhaust volume can be made larger or smaller than the intake volume. Further, the exhaust amount of each exhaust device 10 can be individually adjusted. As a result, although the details will be described later, when the floating matter F moves away from the predetermined position for some reason, by individually controlling the exhaust device 10 and the intake device 20, the floating matter F can be returned to the predetermined position. can be done. In addition, the floating matter F is not limited to staying at a predetermined position, but by individually controlling the exhaust device 10 and the suction device 20, the floating matter can be moved up and down, or moved along a predetermined path in the performance space. It is also possible to perform an effect such as moving.

The production system 100 further includes a position detection sensor 30 for detecting the position of the floating object F within the production space. In this embodiment, an optical sensor is used as the position detection sensor 30 . An example of an optical sensor is a TOF (Time Of Flight) sensor. Specifically, the optical sensor projects a pulse of laser light such as infrared light from a light emitting element, and measures the time it takes for this laser light to reflect off an object (floating matter F) and return to the light receiving element. . It is preferable to install the optical sensors at a plurality of locations such as the ceiling and walls around the performance space. In this way, by projecting the laser light onto the floating object F from the optical sensor, it is possible to obtain coordinate information regarding the position and outline of the floating object F within the presentation space. Further, as shown in FIG. 2, detection information obtained by the position detection sensor 30 is input to a control device 40 configured by a known PC or the like. Based on the information measured by the position detection sensor 30, the control device 40 executes arithmetic processing for calculating the distance from the sensor to the object and the coordinate values of the object in the performance space.

Although not shown, the position detection sensor 30 can also be configured with a transmitter mounted inside the floating object F (ball) and a receiver provided on the ceiling or wall near the production space. is. In this case, the radio signals emitted from the transmitter inside the floating object F are received by a plurality of receivers, and the reception strength of the radio signals received by these plurality of receivers is analyzed by the control device 40, It is possible to acquire the positional information of the floating object F in the production space.

Information detected by the position detection sensor 30 is used to control the floating state of the floating object F. FIG. As shown in FIG. 4, detection information of the position detection sensor 30 is transmitted to the control device 40 via the main bus. The control device 40 is a PC (computing processing device) containing a control program, and performs individual control of each exhaust device 10 and intake device 20 . Specifically, the control device 40 controls the volume or velocity of air to be exhausted from each of the exhaust devices 10 , and controls the volume or velocity of air to be taken from the intake device 20 .

As an example of the control method by the control device 40, the conditions for operating each of the exhaust devices 10 and the intake devices 20 are programmed in the control device 40 in advance in conjunction with the coordinate values of the floating matter F detected by the position detection sensor 30. be kept. FIG. 3 shows an example of a control flow by the control device 40. As shown in FIG. As shown in step S1 in FIG. 3, the control device 40 basically controls the exhaust device 10 and/or the intake device 20 so that the floating object F continues to float near the center of the performance space. (floating control mode). On the other hand, as in steps S2 and S3, when it is detected by the information from the position detection sensor 30 that the floating object F has left the vicinity of the center of the effect space by a certain distance or more, the control device 40 controls the exhaust device 10 and/or Alternatively, by controlling the intake device 20, control is performed to return the floating matter F to the vicinity of this center (return control mode). For example, when the coordinate value of the floating matter F approaches the floor surface, the air volume of the exhaust device 10 and/or the suction device 20 is increased to lift the floating matter F upward. On the other hand, when the coordinate values of the floating matter F approach the air intake device 20 or the ceiling, the air volume of the exhaust device 10 and/or the air intake device 20 is reduced so that the floating matter F is not drawn into the air intake device 20. do it. In addition, when the floating object F moves to a position biased in the front, back, left, and right of the production space, for example, the air volume from the exhaust device 10 provided near the vicinity of the floating object F after movement is increased, and the floating object F moves to the space. Generate an air current that returns to the center. Also, as in step S4, when the information from the position detection sensor 30 detects that the floating object F has returned to the vicinity of the center of the effect space, the control device 40 shifts from the above-described return control mode (step S3) to the floating control mode. mode (step S1).

Further, the control processing by the control device 40 described above can also be realized using artificial neural networks (deep learning, etc.) and machine learning such as reinforcement learning. For example, deep learning is performed using a data set of the operation of each exhaust device 10 (a) to (d) and the intake device 20 and the state change of the floating matter F due to the operation as teacher data, and the learned model obtained as a result. may be used for the control processing of the control device 40 . As a result, referring to the learned model, each exhaust device 10 (a) to (d) and the intake device 20 are efficiently operated so that the floating state is optimized according to the behavior of the floating matter F. can be operated. For example, when performing reinforcement learning, the floating object F is in an appropriate position in the production space and the floating state is stable. The various devices 20 and 30 may be controlled to maximize the reward or minimize the punishment by giving punishment to the environment to which it is attached. In this way, by using machine learning, it is possible to efficiently optimize the behavior of the floating object F, which changes depending on the environment (for example, airflow) in the production space.

A ball is used as an example of the floating object F in this embodiment. This ball is a ball 2, which is a hollow sphere containing gas such as air, nitrogen, or helium. The outer membrane of the ball is preferably made of a transparent or translucent soft flexible material. Examples of ball-forming materials are silicone and synthetic rubber. The ball preferably has, for example, a diameter of 0.1 m to 5 m or a diameter of 0.5 to 3 m, particularly preferably a diameter of 1 m to 2.5 m. It is recommended that the ball should be made of a relatively lightweight material and that it should be able to float freely over the audience's head in the production space while maintaining a certain amount of time in the air. Also, one or a plurality of balls can be prepared according to the size of the performance space. Moreover, like the ball disclosed in Patent Document 1 and Patent Document 2, it is also possible to mount a lighting device such as an LED and a speaker inside the ball.

Hereinafter, although illustration is omitted, an arbitrary configuration of the production system 100 will be described. The production system 100 may further include speakers in the room containing the production space. For example, speakers are installed near the walls and ceiling of a room. The speaker is also connected to the control device 40 . The control device 40 controls sound effects such as BGM and sound effects emitted from the speaker. Further, the control device 40 may receive positional information and the like of the floating object F from the position detection sensor 30 via the main bus, and control the sound output from the speaker based on this positional information. For example, it is possible to change BGM and sound effects according to the position of the floating object F in the production space.

The production system 100 may further include a projector that projects image light onto the floating object F. For example, two projectors are installed at symmetrical positions with respect to the center of the performance space. Therefore, two projectors can project image light from both the left and right sides onto the floating object F floating near the center of the performance space. As a result, the image light can be projected onto almost the entire floating object F. Note that the number of projectors can be appropriately increased or decreased in consideration of, for example, the size of the performance space and the size of the floating object F. Also, the projector may be installed near the ceiling of the room containing the performance space. The projector is connected to the control device 40 and projects image light onto the floating object F under the control of the control device 40 .

The control device 40 can also perform so-called projection mapping on the floating matter F by controlling each projector. The control device 40 stores a CG image or the like to be projected onto the floating object F, and projects this image from each projector. Also, the control device 40 acquires the coordinate information of the outline of the floating object F from the position detection sensor 40 via the main bus. Based on the coordinate information of the floating object F, the control device 40 changes the image projected from each projector in real time and controls the projection direction of the image light. For example, the control device 40 may change the content of the image projected onto the floating object F or the color of the light according to the size, shape, or floating position of the floating object F. As a result, effective projection mapping can be performed using the surface of the floating object F floating in the production space as a projection plane.

The production system 100 may further include lights for illuminating the production space or the floating object F. For example, a ceiling light is provided near the ceiling of the room containing the production space. Further, for example, a moving light is provided above the center of the performance space, and irradiates the floating object F with illumination light. Also, for example, the floor light is provided on the floor surface of the room containing the production space. These lights are connected to the controller 40 . The control device 40 controls the amount (brightness) of the illumination light of each light, the color of the light, and blinking. In particular, the control device 40 can control the irradiation direction of light from the moving light. Specifically, the control device 40 preferably receives coordinate information of the floating object F from the position detection sensor 30 and controls the irradiation direction of the moving light based on this coordinate information. For example, the irradiation direction of the moving light can be controlled so that the floating matter F is irradiated with light.

FIG. 1 schematically shows one performance space and a performance system 100 that generates airflow there. However, a plurality of production systems 100 can be arranged side by side in the same room. In this way, a plurality of performance spaces may be formed in one room.

In the specification of the present application, the embodiments of the present invention have been described with reference to the drawings in order to express the content of the present invention. However, the present invention is not limited to the above embodiments, and includes modifications and improvements that are obvious to those skilled in the art based on the matters described in this specification.
