Problems to be solved by the application

However, the apparatuses described in patent documents 1 and 2 do not have a means for controlling the position of the float in the playing space, but are limited to tracking the float that moves freely in the space. It is therefore a primary object of the present application to provide a system for controlling the float condition of a float in a show space.

Means for solving the problems

The first aspect of the application relates to a performance system for floating a float in the air. Further, in the present specification, "float" means a tangible object having a certain rigidity that floats in the air by an air flow. Examples of the float are balls, balloons, cotton, feathers, and the shape thereof is not particularly limited. For example, the float is not limited to a sphere, but may be a polyhedron. Also, a device that can autonomously float by an air flow, such as an autonomous flying type unmanned aerial vehicle, is also included in what is referred to herein as a float. On the other hand, intangibles such as gas, mist, bubbles, or the like or objects destroyed by contact with other objects are excluded from what is referred to herein as a float. The show system of the present application includes a plurality of exhausts. The plurality of exhaust devices are configured to generate an air flow clockwise or counterclockwise in plan view in the playing space surrounded by the exhaust ports. The number of the exhaust devices may be two or more, preferably three or more or four or more, or five or more. For example, when the number of exhaust devices is two, the respective exhaust ports may be arranged so that the air exhausted from the exhaust ports is offset, thereby generating a vortex-like air flow in the room. For example, when the number of exhaust devices is four, exhaust ports of the exhaust devices may be arranged at four corners of the room, and air may be discharged clockwise or counterclockwise from the exhaust ports to generate a vortex-like air flow in the room. Thus, the show system of the present application floats on the air flow in the show space.

In the system of the present application, the float is preferably configured to contain the gas through a flexible outer membrane. Examples of floats are balls or balloons. Further, lighting devices such as LEDs and speakers can be mounted in advance in the interior of the float as disclosed in patent document 1 and patent document 2.

The system of the present application further comprises an air suction device. The air suction device is arranged above the playing space and is provided with the air suction device or an air suction port thereof in a mode of sucking the air discharged by the air discharge device. By providing the suction device above the room, a cyclone-like updraft can be generated in the room. This makes it easy to maintain the floating state of the float.

The system of the present application preferably further comprises a sensor and a control device. The sensor is used to detect the position of a float within the show space. The control device controls the air volume or the air speed generated by the air exhausting device and/or the air sucking device based on the detection information of the sensor. In this way, by feedback-controlling the exhaust device and the intake device using the detection information of the sensor, it becomes easy to stay the float at a predetermined position in the show space (for example, the center of the show space). And, when the float deviates from the predetermined position in the show space, the float can be returned to the predetermined position in the show space by feedback-controlling the air discharging means and the air sucking means. In the control of the exhaust device and the intake device, the air volume or the air velocity may be controlled by setting specific conditions and critical values for the position of the float, or by using a known machine learning algorithm such as deep learning or reinforcement learning.

The second side of the present application is a performance method of floating a float in the air. The performance method of the application comprises the following steps: a step of exhausting air through the plurality of exhaust devices in such a manner that an air flow clockwise or counterclockwise in plan view is generated in a room surrounded by the exhaust ports of the plurality of exhaust devices; and a step of floating the float in the show space by the air flow.

Effects of the application

According to the present application, a system and method for controlling the floating state of a float in a show space may be provided.

Detailed Description

The mode for carrying out the present application will be described below with reference to the drawings. The present application is not limited to the following embodiments, and includes embodiments which can be appropriately modified by those skilled in the art from the following embodiments within the scope of the present application.

Fig. 1 is a perspective view showing an outline of a performance system 100 for floating a float F. Fig. 2 is a block diagram showing various devices constituting the performance system 100. As shown in fig. 1, in the present embodiment, a ball is assumed as a float F. In the illustrated example, although there is only one float F (ball), a plurality of balls can be floated simultaneously in the present system. In addition, the performance system of the present application can handle various floats in addition to the balls.

Basically, the purpose of the performance system 100 of the present application is to maintain a predetermined height at which the float F floats in the air or to move the float F up and down in a performance space provided in a room. When the float F is touched by a viewer or the like, the float F moves in the performance space due to the impact thereof, but according to the performance system 100, control may be performed to return the moving float F to the vicinity of the center of the performance space. The show system 100 generates airflow in a show space surrounded by exhaust ports of the exhaust devices 10 by a plurality of exhaust devices 10 and an intake device 20. Then, the float F floats in the show space by controlling this air flow. In the present embodiment, four exhaust devices 10 (a) to (d) are provided to define a certain room, but the number of exhaust devices 10 per room is not limited to this, and may be, for example, two to ten. In this presentation space, the air flow in the space is preferably restricted by a wall, a partition, or a shower, not shown, so as not to flow in an air flow other than the air flow generated by the plurality of exhaust devices 10 and the air intake devices 20 included in the presentation system 100. And, the show space has a volume (lateral width, longitudinal depth, and height) to the extent that a person can enter. For example, it is preferable that the width, depth and height of the playing space are at least 2m to 5m, respectively, and the volume of the playing space can be ensured.

As shown in fig. 1, in the present embodiment, it is assumed that the playing space is formed in a planar quadrilateral shape (in particular, a planar square shape). A plurality of columns 11, which are columns for exhaust, are erected at the four corners of the room. The four gas columns 11 (a) to (d) are provided with a plurality of exhaust ports 12 (a) to (d), and the exhaust devices 10 (a) to (d) are connected to each other. Thus, the air sent from the plurality of air discharge devices 10 passes through the inside of the air column 11 and is discharged from the air discharge ports 12 provided on the side surfaces of the air column 11. As shown in fig. 1, the four exhaust ports 12 (a) to (d) provided for each of the four air columns 11 are configured to set the exhaust direction of the air in each of the exhaust ports 12 (a) to (d) so as to generate a clockwise or clockwise vortex-like air flow in the playing space in a plan view. Specifically, in the example shown in fig. 1, the first exhaust port 12 (a) discharges air in the direction toward the second exhaust port 11 (b), the second exhaust port 12 (b) discharges air in the direction toward the third exhaust port 12 (c), the third exhaust port 12 (c) discharges air in the direction toward the fourth exhaust port 12 (d), and the fourth exhaust port 12 (d) discharges air in the direction toward the first exhaust port 12 (a). It is needless to say that the discharge direction of each of the exhaust ports 12 (a) to (d) may be set to be opposite to the direction shown in fig. 2. By setting the exhaust direction of the exhaust ports 12 (a) to (d) in this way, a vortex-like airflow is generated in the room. In the present embodiment, the number of the exhaust device 10 and the number of the gas columns 11 are four, but the number of these may be increased or decreased according to the arrangement environment.

In the embodiment shown in fig. 1, a suction device 20 for sucking air discharged from each of the exhaust ports 12 is provided above the vicinity of the center of the playing space. In the present embodiment, the propeller-shaped air suction device 20 (ceiling fan) is provided above the room, but the main body of the air suction device 20 may be provided in advance in another place, and the air inlet to the air suction device 20 may be provided above the room. In the present embodiment, the air intake device 20 is provided near the ceiling of the show space, and the height from the floor to the air intake device 20 may be set to 2 to 10m, for example. The air intake device 20 may be located 1 to 2m or more above the air outlet 12. As a result, when the air discharged from each of the air outlets 12 is sucked through the air inlet 2, a cyclone-like upward air flow can be generated in the playing space surrounded by each of the air outlets 12.

In the present embodiment, the respective exhaust devices 10 (a) to (d) and the intake device 20 can control the air volume and the air velocity independently of each other. For example, the amount of exhaust gas from the entire plurality of exhaust devices 10 may be equal to the amount of intake gas from the intake device 20, or the amount of exhaust gas may be larger or smaller than the amount of intake gas. The amount of exhaust gas of each exhaust device 10 can be individually adjusted. As described in detail below, when the float F is moved away from the predetermined position for some reason, the exhaust device 10 and the intake device 20 are individually controlled, whereby the float F can be returned to the predetermined position. Further, the float F may be moved up and down or along a predetermined path in a play space by individually controlling the exhaust device 10 and the intake device 20, not being limited to the float F being stopped at a predetermined position.

The show system 100 further comprises a position detection sensor 30 for detecting the position of the float F in the show space. In the present embodiment, a photosensor is used as the position detection sensor 30. An example Of a light sensor is a TOF (Time Of Flight) sensor. Specifically, the photosensor pulses laser light such as infrared light from the light emitting element, and measures the time until the laser light is reflected by the object (float F) and returned to the light receiving element. The light sensor is preferably provided at a plurality of places such as a ceiling and a wall surface around the playing space. In this way, by projecting laser light from the photosensor to the float F, the position of the float F in the show space and coordinate information about the outline thereof can be obtained. As shown in fig. 2, the detection information obtained by the position detection sensor 30 is input to a control device 40 configured by a known PC or the like. The control device 40 performs an arithmetic processing of calculating a distance from the position detection sensor 30 to the object and a coordinate value of the object in the presentation space based on the information measured by the position detection sensor.

Although not shown, the position detection sensor 30 may be composed of a transmitter mounted in the float F (ball) and a receiver provided on the ceiling and wall surface near the playing space. In this case, the plurality of receivers receive the radio signals transmitted from the transmitter inside the float F, and the control device 40 analyzes the reception intensities of the radio signals received by the plurality of receivers, whereby the position information of the float F in the performance space can be acquired.

The detection information of the position detection sensor 30 is used for control of the floating state of the float F. As shown in fig. 4, the 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 (arithmetic processing unit) having a program for control incorporated therein, and performs individual control of each of the exhaust device 10 and the intake device 20. Specifically, the control device 40 controls the air volume or the air velocity of the air to be exhausted for each exhaust device 10, and controls the air volume or the air velocity of the air to be sucked for the suction device 20.

As an example of a control method by the control device 40, the conditions under which the respective exhaust devices 10 and the intake device 20 operate are linked with the coordinate values of the float F detected by the position detection sensor 30, and are programmed into the control device 40 in advance. Fig. 3 shows an example of a control flow performed by the control device 40. As shown in step S1 of fig. 3, basically, the control device 40 controls the air discharging device 10 and/or the air sucking device 20 so that the float F continuously floats near the center of the show space (float control mode). On the other hand, if it is detected that the float F is deviated from the vicinity of the center of the playing space by a predetermined distance or more based on the information from the position detection sensor 30 as in steps S2 and S3, the control device 40 controls the exhaust device 10 and/or the intake device 20 to perform control (reset control mode) for resetting the float F to the vicinity of the center. For example, when the coordinate value of the float F approaches the ground, the air volume of the air discharge device 10 and/or the air suction device 20 is increased to raise the float F upward. On the other hand, when the coordinate value of the float F approaches the air intake device 20 and the ceiling, the air volume of the air exhaust device 10 and/or the air intake device 20 may be reduced so long as the float F is not sucked by the air intake device 20. When the float F moves to a position offset to the front, rear, left, and right of the playing space, for example, the air volume from the air discharge device 10 provided near the moved float F is increased, and an air flow for returning the float F to the center of the space is generated. Then, as in step S4, when it is detected by the information from the position detection sensor 30 that the float F has returned to the vicinity of the center of the playing space, the control device 40 shifts from the above-described reset control mode (step S3) to the float control mode (step S1).

The control process performed by the control device 40 may be performed by machine learning such as artificial neural network (deep learning or the like) or reinforcement learning. For example, the data sets of the respective exhaust devices 10 (a) to (d) and the suction device 20 and the state change of the float F due to the operation thereof may be subjected to deep learning as training data, and the learning model obtained as a result thereof may be used for the control process of the control device 40. Thus, by referring to the learned model, the respective exhaust devices 10 (a) to (d) and the intake device 20 can be effectively operated so as to optimize the floating state thereof in response to the behavior of the floating object F. For example, in the case of performing reinforcement learning, it is sufficient to give a reward to an environment where the float F is in place in the performance space and its floating state is stable, or to give a penalty to an environment where the float F is attached to the floor or ceiling, and to control the various devices 20, 30 in such a manner that the reward is maximized or the penalty is minimized. In this way, by using machine learning, the behavior of the float F that varies depending on the environment (for example, air flow) in the performance space can be effectively optimized.

In the present embodiment, a ball is used as an example of the float F. The ball 2 is a hollow ball body including air, nitrogen, helium, or the like. The outer membrane of the ball is preferably formed of a soft, pliable material that is transparent or translucent. Examples of materials forming the ball are silicone or synthetic rubber. The balls are, for example, preferably from 0.1 to 5m in diameter or from 0.5 to 3m in diameter, particularly preferably from 1 to 2.5m in diameter. The recommended ball is formed of a relatively light material and can float freely in the performance space while maintaining a dead time at the head of the audience. And, the ball may be prepared in one or more pieces in accordance with the size of the playing space. Further, as the balls disclosed in patent document 1 and patent document 2, a lighting device such as an LED and a speaker may be mounted in advance in the ball.

Hereinafter, although not shown, an arbitrary configuration of the performance system 100 will be described. The show system 100 may also further include speakers within the house including the show space. For example, speakers are provided near the wall surface and ceiling of a house. The speaker is connected to the control device 40. The control device 40 controls sound effects such as BGM and effect sound emitted from the speaker. The control device 40 can receive the position information of the float F from the position detection sensor 30 via the main bus, and control the sound output from the speaker based on the position information. For example, BGM or effect sound can be changed in response to the position of the float F in the performance space.

The performance system 100 may further include a projector that projects image light onto the float F. For example, two projectors are provided at symmetrical positions with the center of the presentation space interposed therebetween. Therefore, the image light can be projected from both left and right sides onto the float F floating near the center in the rendering space by the two projectors. This allows the image light to be projected on the substantially entire float F. The number of projectors may be appropriately increased or decreased in consideration of, for example, the size of the presentation space or the size of the float F. The projector may be provided in advance near the ceiling of a house including the performance space. The projector is connected to the control device 40, and projects image light onto the float F in accordance with the control of the control device 40.

The control device 40 can control the projectors so as to project the float F in a so-called light engraving. The control device 40 stores CG images and the like projected on the float F, and projects the CG images from the respective projectors. The control device 40 obtains coordinate information of the outline of the float F from the position detection sensor 40 via the main bus. Based on the coordinate information of the float F, the control device 40 changes the image projected from each projector in real time or controls the projection direction of the image light. For example, the control device 40 may change the content of the image projected to the float F and the color of the light according to the size, shape, or floating position of the float F. Thus, the surface of the float F floating in the playing space can be used as a projection surface, and the light carving projection can be performed effectively.

The show system 100 may also be further provided with a lamp for illuminating the show space or float F. For example, a ceiling lamp is provided near a ceiling of a house including a performance space. For example, a head lamp is provided above the center of the playing space, and the float F is irradiated with illumination light. And, for example, a floor lamp is provided on the floor of a house including the performance space. The lamps are connected to a control device 40. The control device 40 controls the light quantity (brightness), light color, and flicker of the illumination light of each lamp. In particular, the control device 40 may control the direction of illumination of the light of the moving head lamp. Specifically, the control device 40 receives the coordinate information of the float F from the position detection sensor 30, and can control the irradiation direction of the panning lamp based on the coordinate information. For example, the irradiation direction of the moving head lamp may be controlled to irradiate light to the float F.

In fig. 1, a show space and a show system 100 in which an air stream is generated is schematically shown. However, a plurality of performance systems 100 may be arranged in the same room. In this way, a plurality of rendering spaces can be formed in one room.

In the above description of the present application, embodiments of the present application are described with reference to the drawings in order to represent the contents of the present application. However, the present application is not limited to the above-described embodiments, and includes modifications and improvements obvious to those skilled in the art based on the matters described in the present specification.
