[Modes for carrying out the invention] 【0009】 <First Embodiment> Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. In the drawings for explaining the embodiments, the same components are generally denoted by the same reference numerals, and repeated explanations thereof are omitted. FIG. 1 is an external view of a system for controlling the spatial arrangement of a group of fine particles according to the first embodiment of the present invention. 【0010】 (1) Outline of the First Embodiment The outline of this embodiment will be described. As shown in FIG. 1, a system 1 for controlling the spatial arrangement of a group of fine particles is, for example, a system that generates a group of fine particles in a predetermined indoor space. Here, the group of fine particles refers to a group of fine and fluid substances that are generated by crushing a liquid or a solid by external energy, have a certain coherence, and float in space. Examples of the group of fine particles include clouds generated in nature. Note that the system 1 for controlling the spatial arrangement of a group of fine particles is not limited to indoor use and may be used outdoors. 【0011】 That is, the system 1 for controlling the spatial arrangement of a group of fine particles is a system that artificially generates an object (hereinafter referred to as an artificial cloud) imitating a cloud indoors. The artificial cloud generated indoors is used, for example, for viewing. The system 1 for controlling the spatial arrangement of a group of fine particles generates an artificial cloud having a shape desired by the user. 【0012】 The user inputs the appearance information of the sky to be generated to the control unit 60 by selecting image data displayed on the operation terminal 70 (e.g., selecting from a plurality of photos of the sky) or selecting conditions (e.g., inputting a predetermined area and a predetermined time). Examples of the operation terminal 70 include a mobile terminal such as a smartphone. The input operation may be performed via the operation terminal 70 or may be performed by directly inputting to the control unit 60 described later. 【0013】 (2) Overall Configuration of the System 1 for Controlling the Spatial Arrangement of a Group of Fine Particles The configuration of the system 1 for controlling the spatial arrangement of a group of fine particles will be described. FIG. 2 is a block diagram showing the configuration of the system for controlling the spatial arrangement of a group of fine particles shown in FIG. 1. 【0014】 As shown in FIGS. 1 and 2, the spatial arrangement control system 1 for the fine particle group includes a fine particle group generation unit 10, a recognition unit 20, an irradiation unit 30, a diffusion unit 40, a light source unit 50, a control unit 60, and a frame 90 (see FIG. 1). 【0015】 The fine particle group generation unit 10 generates a fine particle group by applying energy from the outside to a liquid or a solid. application The fine particle group generation unit 10 atomizes by applying energy to water, oil, or inorganic substances. application By doing so. The energy applied by the fine particle group generation unit 10 application can be various types of energy such as ultrasonic waves, electricity, and heat. The specific structure of the fine particle group generation unit 10 will be described later. 【0016】 The recognition unit 20 recognizes the form of the fine particle group generated by the fine particle group generation unit 10. The recognition unit 20 recognizes the spatial region where the fine particle group stays by using an image sensor (image recognition sensor) such as a CMOS. A USB camera with about 100,000 to 10 million pixels, which is generally used for image processing and the like, can be used for the recognition unit 20. 【0017】 The irradiation unit 30 irradiates the fine particle group generated by the fine particle group generation unit 10 with electromagnetic waves to remove a part of the fine particle group by evaporation or ablation. Thereby, the fine particle group in a predetermined space is formed. The electromagnetic wave may be any of infrared rays, ultraviolet rays, visible light, etc. The irradiation unit 30 has a function of forming the fine particle group into a shape desired by the user by disappearing the fine particle group outside the range desired by the user. The specific structure of the irradiation unit 30 will be described later. 【0018】 The diffusion unit 40 diffuses the fine particle group generated by the ultrasonic oscillator 16 into a predetermined space. The diffusion unit 40 diffuses the fine particle group into a predetermined space by, for example, blowing air to the fine particle group generated by the ultrasonic oscillator 16. Note that the diffusion unit 40 may diffuse the fine particle group into a predetermined space by sucking the air in the predetermined space. 【0019】 The light source unit 50 irradiates the group of microparticles generated by the microparticle group generation unit 10 with visible light. The light source unit 50 is installed, for example, on the ceiling. The light source unit 50 may also be a general lighting fixture. 【0020】 Furthermore, the light source unit 50 may illuminate a background that mimics the sky. In other words, the light source unit 50 can be a flat panel that displays the sky, which serves as the background for the group of fine particles that constitute the artificial cloud. The light source unit 50 adjusts the color tone and light intensity according to commands output from the control unit 60, based on morphological information input by the user. Here, morphological information refers to information indicating the morphology of the group of fine particles desired by the user. 【0021】 A panel-type light source can also be used for the light source unit 50. It is preferable to use one that can change the light intensity and color so that it can express changes in the sky over time. For example, different colored LEDs could be used to represent the morning, midday, and evening skies. 【0022】 The light source unit 50 is preferably highly waterproof, taking into consideration its resistance to the mist, which is the group of fine particles emitted from the fine particle group generation unit 10. The light source unit 50 is preferably equipped with a communication function so that it can communicate with the control unit 60. 【0023】 The control unit 60 controls the irradiation unit 30 by comparing the morphology of the microparticle group recognized by the recognition unit 20 with morphology information indicating the morphology of the microparticle group to be molded. The control unit 60 has a reception unit 61. The reception unit 61 receives input of morphology information. The specific configuration of the control unit 60 will be described later. 【0024】 Frame 90 is a structure that supports each member. The frame 90 comprises an aluminum frame 90 framework, which is commonly used in industrial equipment, and a cover made of metal or resin. Of the frame 90, the color of the part visible to the user is preferably an inconspicuous color such as white, so as not to affect the aesthetic appearance of the simulated sky that is modeled by the group of fine particles that constitute the artificial cloud. 【0025】 (2-1) Configuration of the microparticle cluster generation unit 10 The configuration of the fine particle cluster generation unit 10 will now be described. Figure 3 is a cross-sectional view showing the structure of the fine particle cluster generation unit 10. As shown in Figure 3, the particulate matter generation unit 10 includes a water storage tank 11, a water supply tube 12, a water supply pump 13, an atomization chamber 14, a float switch 15, an ultrasonic transducer 16, and a nozzle 17. In the following description, the particulate matter will be referred to as mist. 【0026】 The water storage tank 11 stores the liquid (such as tap water) that will be used as the raw material for the mist, which consists of fine particles. The material of the water storage tank 11 is preferably an inexpensive, lightweight, and corrosion-resistant resin material such as polyethylene or polypropylene. The capacity is preferably about 10 to 30 liters so that a large amount of mist can be generated with a single water supply. In addition to water, the liquid stored in the water storage tank 11 may also be hypochlorous acid water with disinfectant properties, or a solution to which fragrance components have been added. A water supply tube 12 is inserted inside the water storage tank 11. 【0027】 The water supply tube 12 connects the inside of the water storage tank 11 to the inside of the atomization chamber 14. The water supply tube 12 draws liquid from the water storage tank 11 to the atomization chamber 14. The material of the water supply tube 12 is preferably a water-resistant resin material (such as polyurethane, PVC, or fluororesin). 【0028】 The water supply tube 12 is preferably transparent so that air bubbles and other particles inside can be easily seen. To facilitate routing, the inner diameter of the water supply tube 12 is preferably about 6 to 20 mm. A water supply pump 13 is provided in the middle of the water supply tube 12. 【0029】 The water supply pump 13 is the driving source of the suction force that transfers the liquid stored in the water storage tank 11 to the atomization chamber 14. A diaphragm pump, commonly used for water pumping and the like, can be used as the water supply pump 13. The water supply pump 13 supplies water from the water storage tank 11 into the atomization chamber 14 based on a command from the control unit 60. The amount of water in the atomization chamber 14 is detected by the float switch 15. 【0030】 The atomization chamber 14 is composed of a housing that has a rectangular parallelepiped-shaped space inside. Liquid supplied from the water storage tank 11 is stored inside the atomization chamber 14. Within the atomization chamber 14, a stagnant space is formed where the atomized water floats as a gas. The material of the housing constituting the atomization chamber 14 is preferably a corrosion-resistant metal (aluminum, stainless steel, etc.). 【0031】 The float switch 15 is located inside the atomization chamber 14. The float of the float switch 15 moves up and down in accordance with the change in water level, thereby detecting the water level inside the atomization chamber 14. The float switch 15 detects when the liquid level in the atomization chamber 14 has reached the appropriate level to prevent excessive liquid levels, and transmits a signal to the control unit 60. The control unit 60 outputs a water supply OFF signal to the water supply pump 13 according to the input from the float switch 15. A float switch 15 similar to those used in general humidifiers can be used. 【0032】 The ultrasonic transducer 16 is located at the bottom of the housing that constitutes the atomization chamber 14. The ultrasonic transducer 16 atomizes the liquid into fine particles by ultrasonic vibration, generating a group of fine particles. As the ultrasonic transducer 16 vibrates, the liquid stored at the bottom of the atomization chamber 14 is broken down by the vibration and atomized. A piezoelectric element with a frequency of approximately 1 to 5 MHz can be used as the ultrasonic transducer 16. 【0033】 For example, using a piezoelectric element with a frequency of 1.6 MHz or 2.4 MHz, mist with particle sizes of approximately 4 μm and 3 μm, respectively, can be generated. Since finer particle sizes allow for the generation of denser (more visible) mist with less water, it is preferable to use a piezoelectric element with a higher frequency. The atomization rate is preferably 1 to 30 L / h. The atomized water floats in the stagnant space within the atomization chamber 14. 【0034】 The nozzle 17 is provided in a part of the housing that constitutes the atomization chamber 14, and forms an opening that connects the inside of the atomization chamber 14 to the outside. In the illustrated example, the base of the nozzle 17 is connected to the top surface of the housing. The nozzle 17 discharges the mist that remains in the atomization chamber 14 from the discharge port at its tip toward a predetermined space. In order to represent mist that slowly drifts in the predetermined space, it is preferable that the discharge speed is low and the discharge range is wide. For this reason, it is preferable that the nozzle 17 has a shape in which the inner diameter gradually increases from the base toward the tip. 【0035】 Furthermore, since the group of fine particles tends to move in the direction of gravity, it is preferable that the discharge direction of the nozzle 17 be directed diagonally upward. The material of the nozzle 17 is preferably a water-resistant resin (such as polypropylene or polyethylene) that is easy to mold. The discharge port of nozzle 17 may be covered with a porous filter. This makes it possible to maintain a constant particle size in the fine particle group and generate a high-concentration fine particle group. 【0036】 A blower fan 41, which serves as a diffusion unit 40, is connected to the particulate matter generation unit 10. The blower fan 41 is located on the opposite side of the nozzle 17 from the housing that constitutes the atomization chamber 14. The enclosure is designed so that air blown from the blower fan 41 flows into the stagnant space within the atomization chamber 14. Therefore, when the blower fan 41 blows air, an airflow is generated that sends the mist generated by the ultrasonic transducer 16 towards the nozzle 17. This airflow sends the mist floating in the stagnant space towards the nozzle 17, and the mist is released to the outside of the housing through the nozzle 17. 【0037】 It is preferable that the blower fan 41 be capable of not only ON / OFF control but also flow rate adjustment, so that the amount of mist discharged from the mist nozzle 17 can be adjusted. Furthermore, since it will be used in an environment filled with fog, it is preferable to use a fan with high moisture resistance. The blower fan 41 blows air based on commands from the control unit 60. 【0038】 (2-2) Configuration of the irradiation unit 30 The configuration of the irradiation unit 30 will now be described. Figure 4 is a cross-sectional view showing the structure of the irradiation unit 30. As shown in Figure 4, the irradiation unit 30 comprises a drive unit 31 (actuator), an infrared heater 32, a reflector 33, a visible light cut filter 34, a heat sink 35, a cooling fan 36, and a housing 37. The irradiation unit 30 is integrated with the recognition unit 20. 【0039】 The drive unit 31 is driven by control from the control unit 60. The drive unit 31 is a means of moving the integrally configured recognition unit 20 and illumination unit 30 to the optimal position. The drive unit 31 can employ a pan-tilt mechanism, similar to those used in surveillance cameras, as an actuator that is small in size and can control the mounted object in any direction. 【0040】 The infrared heater 32 is an infrared radiation source that heats the group of particles non-contact, causing them to evaporate or burn out. In other words, in the illustrated example, the irradiation unit 30 irradiates the group of particles with infrared radiation as electromagnetic waves. For the infrared heater 32, it is preferable to use a carbon fiber heater as a heater that can generate light with a wavelength of around 3 μm, which has a fast irradiation start-up and is easily absorbed by the mist, which is a group of fine particles. The output of the infrared heater 32 is preferably around 500 to 5000 watts. 【0041】 The reflector 33 reflects the infrared light emitted from the infrared heater 32 and emits it as parallel light. The reflector 33 can be a reflector 33 used in parallel-light type far-infrared line heaters, etc. The material of the reflector 33 is preferably a mirror-polished metal (aluminum, stainless steel, etc.). 【0042】 The inside of the reflector 33 may be coated with an infrared reflective film that absorbs visible light in order to reduce the irradiation of visible light components. As a coating material with high infrared reflectivity and visible light absorption for such an infrared reflective film, a black pigment made from metal compounds such as Si, Al, Zr, and Ti can be selected. 【0043】 The visible light cut filter 34 is a filter that transmits only invisible infrared light. By providing the visible light cut filter 34, it is possible to prevent visible light such as red light from being transmitted from the infrared heater 32, thereby preventing it from affecting the appearance of the simulated sky that is modeled by the artificial clouds. As the visible light cut filter 34, a colored glass that transmits infrared light and absorbs visible light can be used. 【0044】 The heat sink 35 is a component that dissipates the residual heat from the infrared heater 32. It is preferable to use a metal with good thermal conductivity (such as aluminum or copper) that is commonly used as a heat dissipation material for the heat sink 35. 【0045】 The cooling fan 36 dissipates the heat absorbed by the heatsink 35 into the air. The cooling fan 36 can accommodate a standard DC fan with a size of approximately 10 to 100 mm square. 【0046】 The housing 37 is a component that serves as the enclosure for the irradiation unit 30. The housing 37 has the function of insulating the infrared heater 32 so that the heat from the infrared heater 32 is not transferred to the recognition unit 20 or the drive unit 31. The material of the housing 37 is preferably a heat-resistant resin (polyimide, PPS, PSU). 【0047】 Next, the operating principle of the irradiation unit 30 will be explained. The infrared light emitted from the infrared heater 32 of the irradiation unit 30 is reflected by the reflector 33 and irradiated onto the group of particles as parallel light. A visible light cut filter 34, positioned in front of the infrared heater 32 in the irradiation direction, cuts out the visible light component, so that only invisible infrared light is irradiated onto the group of particles. 【0048】 The residual heat generated from the infrared heater 32 is absorbed by the heat sink 35 and then dissipated to the outside by the cooling fan 36. Since the irradiation unit 30 is covered by an insulated housing 37, heat transfer to surrounding materials is suppressed. Although not shown in the diagram, as a measure against overheating, an overheat detection sensor such as a thermostat may be provided in the irradiation unit 30, and the power supply to the infrared heater 32 may be turned OFF when the temperature rises above a threshold. 【0049】 Multiple irradiation units 30 may be provided. In this case, the multiple irradiation units 30 may be arranged at positions opposite to each other with respect to a predetermined space in which the particle group generation unit 10 generates a group of particles. Opposite positions are positions that are on opposite sides of each other with respect to the center of the predetermined space. 【0050】 (2-3) Configuration of the control unit 60 The configuration of the control unit 60 will now be described. Figure 5 is a block diagram showing the configuration of the control unit 60. 【0051】 As shown in Figure 5, the control unit 60 includes a processor 61, a storage device 62, a communication interface 63, and an input / output interface 64. 【0052】 The processor 61 is configured to perform the functions of the control unit 60 by launching a program stored in the storage device 62. The processor 61 is an example of a computer. The functions of the processor 61 include, for example, the following: • Function to generate a group of fine particles in the fine particle group generation unit 10. • Function to irradiate the irradiation unit 30 with a group of fine particles. 【0053】 The processor 61 analyzes the information input from the operating terminal 70 and the recognition unit 20, as well as the following information. • Morphology of the group of microparticles to be molded • Morphology of a group of particles floating in a given space • The range to which the irradiation unit 30 should irradiate the group of particles floating in a predetermined space. 【0054】 The processor 61 identifies the morphology of the group of microparticles to be molded from the morphology information input from the user via the operating terminal 70. In other words, the processor 61 is a receiving unit that receives input of morphology information. 61 It functions as such. 【0055】 The processor 61 performs a process to prompt the user to select at least one of the following as morphological information: cloud attributes, namely the shape of the cloud, the seasonal conditions for cloud formation, the temporal conditions, and the regional conditions, and to input this information to the reception unit 61. The shape of the cloud is a name indicating the type of cloud, such as cirrus, cirrocumulus, cumulonimbus, or altostratus. The seasonal, temporal, and regional conditions for cloud formation are indicators that identify the types of clouds that are particularly likely to form in a specific region at a specific time of year or time of day, based on these environmental factors. 【0056】 The processor 61 analyzes the shape of the microparticle group acquired by the image recognition sensor, which is the recognition unit 20, to understand the current form of the microparticle group floating in a predetermined space at that moment. The processor 61 compares the morphology of the microparticle group indicated by the morphological information with the current morphology of the microparticle group to determine the range that the irradiation unit 30 should irradiate to the microparticle group floating in a predetermined space. 【0057】 The processor 61 generates a drive signal to be input to the drive unit 31 and an irradiation signal to be input to the irradiation unit 30. The drive signal is a signal indicating the amount to be driven by the drive unit 31. The irradiation signal is a signal indicating the range, intensity, and duration of irradiation by the irradiation unit 30. 【0058】 The storage device 62 is configured to store programs and data. The storage device 62 is, for example, a combination of ROM (Read Only Memory), RAM (Random Access Memory), and storage (e.g., flash memory or hard disk). 【0059】 The program includes, for example, the following: • OS (Operating System) programs • Programs for applications that perform information processing (e.g., web browsers) 【0060】 The data includes, for example, the following: • Information about cloud attributes presented to the user for selection. • User-entered form information • Information regarding the morphology of the current group of microparticles recognized by the recognition unit 20 【0061】 The input / output interface 64 is configured to receive user instructions from an input device connected to the control unit 60 and to output information to an output device connected to the control unit 60. Input devices include, for example, keyboards, pointing devices, touch panels, or combinations thereof. Output devices include, for example, displays. 【0062】 The communication interface 63 is configured to control communication between the control unit 60 and external devices. The external devices include a particle generation unit 10, an irradiation unit 30, a recognition unit 20, a diffusion unit 40, a light source unit 50, and an operation terminal 70. 【0063】 (3) Control processing The control process of this embodiment will now be described. Figure 6 is a flowchart of the control process in this embodiment. In this explanation, the raw material liquid is water, and the group of fine particles is mist, and each process is described accordingly. 【0064】 As shown in Figure 6, the processor 61 receives morphological information input from the user (S11). Specifically, the processor 61 performs a process to prompt the user to select at least one of the following as morphological information: cloud attributes, namely the shape of the cloud, the seasonal conditions for cloud formation, the temporal conditions, and the regional conditions, and to input this information into the reception unit 61. User input is made via the operation terminal 70. 【0065】 After step S11, the processor 61 performs adjustment of the light source unit 50 (S12). Specifically, the control unit 60 transmits commands to the light source unit 50 to adjust the color tone and light intensity based on the form information input by the user. 【0066】 After step S12, the processor 61 performs a recording of the appearance before fog generation (S13). Specifically, the control unit 60 controls the recognition unit 20 and the illumination unit 30, moves the drive unit 31 so that the recognition unit 20 can image the entire predetermined space, and records the appearance of the predetermined space in its initial state. 【0067】 After step S13, the processor 61 performs the release of mist into a predetermined space (S14). Specifically, the control unit 60 controls the fine particle cluster generation unit 10 and releases the mist by adjusting the flow rate to cover the desired mist generation range obtained from the morphological information. In this process, the fine particle generation unit 10 receives energy from the outside to the liquid. application Then, a mist consisting of fine particles is generated and released into a designated space. 【0068】 After step S14, the processor 61 performs recognition of the fog's stagnation area (S15). Specifically, the control unit 60 controls the recognition unit 20 and the irradiation unit 30, and moves the drive unit 31 to record an image after fog generation. Then, by comparing it with the initial state, it recognizes the fog retention area. 【0069】 After step S15, the processor 61 performs a determination (S16) as to whether the fog meets the required range. Specifically, the control unit 60 compares the fog retention area with morphological information. 【0070】 In step S16, if the fog does not meet the required range (NO in S16), the processor 61 returns to the processing in step S14. Specifically, if the region requested by the morphological information is not filled with fog, the process returns to step S14 and continues to release fog. 【0071】 In step S16, if the fog is within the requested range (YES in S16), the processor 61 performs the removal of fog outside the requested range (S17). Specifically, if the required area is filled with fog, the location of fog remaining outside the required area can be determined from the difference between the required area and the morphological information. 【0072】 The control unit 60 then drives the drive unit 31 to control the position of the irradiation unit 30, and uses the irradiation unit 30 to irradiate the fog that has accumulated outside the required range with infrared rays, thereby eliminating the fog that has accumulated in that area. These processes form the desired mist in a predetermined space (S18). Furthermore, by repeating the series of processes, the mist can maintain a shape that conforms to the morphological information. 【0073】 As described above, according to this embodiment, the fine particle group generation unit 10 generates a group of fine particles. Therefore, the group of fine particles can be continuously supplied to a predetermined space. Then, the irradiation unit 30 irradiates the group of microparticles generated by the microparticle group generation unit 10 with electromagnetic waves to remove a portion of them and shape them. Therefore, even if the particle generation unit 10 continuously supplies particle groups and the range of the particle groups expands too much, the irradiation unit 30 can remove particle groups located in unnecessary areas. As a result, it is possible to create a situation where particle groups are always present in a desired range within a predetermined space. In this way, particle groups can be kept within a certain spatial region. 【0074】 In this way, by generating artificial clouds, which are made up of fine particles, it is possible to faithfully reproduce the feeling of openness one experiences when gazing at a sky filled with clouds outdoors. Clouds, which change shape over time but remain within a certain spatial area overall, can be generated directly indoors, rather than in a partitioned, enclosed space, thus reproducing conditions closer to those outdoors. For example, even in environments where going outside is restricted, such as hospital rooms, a feeling of openness similar to being outdoors can be obtained by generating an artificial cloud indoors using the spatial arrangement control system 1 for a group of fine particles. 【0075】 Thus, by generating a group of microparticles consisting of liquid droplets rather than images or light, the sense of touch can be stimulated by the flow of these microparticles. Furthermore, it is possible to include substances that stimulate the sense of smell or taste, or substances that produce sound when they volatilize, in the raw materials of the particles. For example, by using aromatic components similar to the scent of the seaside, it is possible to recreate the atmosphere of the seaside sky. By appealing to the five senses, it is expected that the parasympathetic nervous system will be activated, and effects such as relaxation and alertness will be obtained. 【0076】 Furthermore, research on 1 / f fluctuations and other phenomena has shown that the natural world contains patterns that include irregular changes within monotony, and that these have a calming effect on humans. Studies have shown that the movement of clouds in nature also exhibits signals similar to 1 / f fluctuations. The microparticles that constitute the artificial cloud generated in this invention, while monotonous in that they remain within a specific range, contain irregular flow, and therefore may potentially produce a similar calming effect. 【0077】 Furthermore, the irradiation unit 30 irradiates the group of particles with infrared radiation as electromagnetic waves. For this reason, the irradiation unit 30 can be constructed with a simple configuration by utilizing a relatively readily available, general-purpose infrared irradiation device. 【0078】 Furthermore, the microparticle cluster generation unit 10 is equipped with an ultrasonic transducer 16 that atomizes a liquid using ultrasonic vibrations to generate a cluster of microparticles. Therefore, compared to configurations that crush solids to create fine particles, it is possible to generate a group of fine particles with less energy. 【0079】 Furthermore, the diffusion unit 40 diffuses the group of fine particles generated by the ultrasonic transducer 16 into a predetermined space. child group By promoting diffusion, it is possible to efficiently retain a group of fine particles in a designated space. 【0080】 Furthermore, the blower fan 41, which acts as the diffusion unit 40, blows air onto the group of fine particles generated by the ultrasonic transducer 16, thereby diffusing the group of fine particles into a predetermined space. As a result, the group of fine particles can be efficiently transported into the predetermined space by being carried by the airflow generated by the blower. 【0081】 Furthermore, the recognition unit 20 recognizes the shape of the microparticle group generated by the microparticle group generation unit 10, and the control unit 60 compares the shape of the microparticle group recognized by the recognition unit 20 with shape information indicating the shape of the microparticle group to be molded, and controls the irradiation unit 30. As a result, the irradiation unit 30 can mold the microparticle group into the shape desired by the user. 【0082】 Furthermore, the control unit 60 has a reception unit 61 that receives input of morphological information, and the control unit 60 performs a process that prompts the user to select at least one of the following as morphological information: cloud shape, seasonal conditions for cloud formation, temporal conditions, and regional conditions, and to input this information into the reception unit 61. Therefore, by selecting the cloud attributes proposed by the control unit 60, the input of the desired form can be simplified. 【0083】 Furthermore, the drive unit 31 is driven by control from the control unit 60. Therefore, it becomes possible to change the position of the irradiation unit 30, giving flexibility to the irradiation pattern of the irradiation unit 30 and enabling the generation of various types of microparticle groups. 【0084】 Furthermore, the irradiation unit 30 is integrated with the recognition unit 20. Therefore, the positional relationship between the recognition unit 20 and the group of microparticles can be made close to the positional relationship between the irradiation unit 30 and the group of microparticles. This reduces the burden on the control processing of the irradiation unit 30, which is performed based on information about the current morphology of the microparticle group obtained from the recognition unit 20. 【0085】 Furthermore, multiple irradiation units 30 may be provided, and the multiple irradiation units 30 may be arranged in positions opposite to each other with respect to a predetermined space. In this case, multiple irradiation units 30 can irradiate the microparticle group with infrared light from positions opposite to each other, enabling efficient shaping of the microparticle group. 【0086】 Furthermore, the light source unit 50 irradiates the microparticle cluster generated by the microparticle cluster generation unit 10 with visible light. This causes the microparticle cluster to scatter visible light, resulting in a visual effect similar to that of natural clouds. 【0087】 Alternatively, the light source 50 may illuminate a background that mimics the sky. In this case, the particles floating indoors can be made to resemble clouds floating in a blue sky, resulting in an even better visual effect. 【0088】 (4) Variations Modifications of this embodiment will now be described. 【0089】 (4-1) Experimental variation 1 Modification 1 will now be described. Modification 1 is an example in which the diffusion unit 40 is equipped with a suction unit 42 for sucking up a group of fine particles. Figure 7 is an external view of the spatial arrangement control system 2 of the group of fine particles according to Modification 1. 【0090】 As shown in Figure 7, the spatial arrangement control system 2 for the particle group comprises a particle group generation unit 10, a recognition unit 20, an irradiation unit 30, a diffusion unit 40, a light source unit 50, and a control unit 60. Of these, the configurations, excluding the diffusion unit 40, are the same as those of the first embodiment, and their description will be omitted. 【0091】 The diffusion unit 40 of the spatial arrangement control system 2 for a group of fine particles is equipped with a suction unit 42 in addition to the aforementioned blower fan 41. The suction unit 42 diffuses the group of fine particles into a predetermined space by drawing in air from that space. In the illustrated example, the suction unit 42 is positioned on the opposite side of the blower fan 41 relative to a predetermined space. The suction unit 42 is positioned between the ceiling and the light source unit 50. 【0092】 When the suction unit 42 draws in air from a predetermined space, the group of fine particles floating in that space are drawn into the suction unit 42 and diffused into the predetermined space. The suction unit 42 may be constructed, for example, by drawing a duct or the like from an existing exhaust system. 【0093】 Thus, in the spatial arrangement control system 2 for a group of fine particles according to the modified example 1, the suction unit 42, which acts as a diffusion unit 40, diffuses the group of fine particles into a predetermined space by sucking in air from that space. Therefore, by positioning the suction unit 42 at a distance from the blower fan 41, the fine particles can be diffused throughout the entire predetermined space. 【0094】 Furthermore, since the suction unit 42 is positioned between the ceiling and the light source unit 50, a flow is created that moves the group of fine particles diagonally upward. Therefore, even if the discharge of the group of fine particles from the nozzle 17 in the fine particle generation unit 10 is slow, the downward movement of the fine particle group is suppressed, and it becomes easier for the particles to spread out in the direction of discharge from the nozzle 17. 【0095】 (4-2) Modification 2 Modification 2 will now be described. Modification 2 is an example that incorporates a dehumidification function. Figure 8 is an external view of the spatial arrangement control system 3 for the group of fine particles according to Modification 2. As shown in Figure 8, the spatial arrangement control system 3 for a group of fine particles comprises a fine particle generation unit 10, a recognition unit 20, an irradiation unit 30, a diffusion unit 40, a light source unit 50, a control unit 60, and a dehumidification unit 80. Of these, the configurations excluding the dehumidification unit 80 are the same as in the first modified example, and their explanation will be omitted. 【0096】 The dehumidifying unit 80 dehumidifies a designated space by sucking in mist, which is a group of fine particles floating in the space, or air heated by infrared irradiation. The dehumidifying unit 80 may be used in combination with the suction unit 42 as shown in the figure, or it may be used alone. The water collected by the dehumidifying unit 80 may be returned to the water storage tank 11. 【0097】 The dehumidification unit 80 may be linked with air conditioning equipment such as heating and cooling systems to reproduce an air environment that meets the user's requirements. In this case, the user can also add conditions related to temperature and humidity to the data input to the control unit 60, and operate the system as one that includes air conditioning functions. 【0098】 Thus, the spatial arrangement control system 3 for the fine particle group according to Modification 2 has a dehumidification function, which enables control of indoor humidity. Therefore, the air environment can be adjusted to meet the user's requirements. In addition, water consumption can be reduced by returning the water recovered by the dehumidification unit 80 to the water storage tank 11. 【0099】 (4-3) Modification example 3 Modification 3 will now be described. Modification 3 is an example in which the particulate matter cluster generation unit 10B is equipped with a UV germicidal lamp 81 (ultraviolet irradiation unit) and a temperature control mechanism 82. Figure 9 is a cross-sectional view showing the structure of the particulate matter cluster generation unit 10B according to Modification 3. 【0100】 The particulate matter generation unit 10 includes a water storage tank 11, a water supply tube 12, a water supply pump 13, an atomization chamber 14, a float switch 15, an ultrasonic transducer 16, a nozzle 17, a UV germicidal lamp 81, and a temperature control mechanism 82. Of these, the components other than the UV germicidal lamp 81 and the temperature control mechanism 82 are the same as those in the first embodiment, and their description will be omitted. 【0101】 The UV sterilization lamp 81 sterilizes at least one of the group of fine particles (mist in this example) generated by atomization within the housing, and the raw material of the group of fine particles (water in this example), by irradiating it with ultraviolet light. The UV sterilization lamp 81 is located inside the housing, between the ultrasonic transducer 16 and the nozzle 17. In this way, by providing the UV germicidal lamp 81, it is possible to suppress the growth of microorganisms within the generated group of fine particles. 【0102】 The temperature control mechanism 82 is located at the bottom of the housing. The temperature control mechanism 82 employs a Peltier temperature control system. Toga Yes, it is possible. The temperature control mechanism 82 adjusts the temperature of at least one of the raw material, water, or the group of fine particles (mist) generated from the raw material. For example, by cooling the group of fine particles, the effect of the temperature rise caused by infrared irradiation from the irradiation unit 30 on the ambient temperature can be offset. 【0103】 Furthermore, by cooling the group of particulate matter, it is possible to avoid the problem of the particulate matter being prone to disappearing under conditions of high ambient temperature and low humidity. By adding a temperature and humidity sensor to part of the spatial arrangement control system 1 for the fine particle group, or by receiving temperature and humidity measurement data from an external device, it is also possible to implement control that adjusts the fog temperature according to the environment. 【0104】 (5) Other variations It is also possible to utilize the ceiling, which is designed to resemble the sky. Furthermore, it is possible to project images of a blue sky or similar onto a large display and use it as a background. As a method to mimic the night sky, one could employ a technique that projects a starry sky or similar image onto the ceiling or walls using a projector. Alternatively, clouds could be generated in the foreground using the projected image on the ceiling as the background. 【0105】 To represent diverse skies, lighting and structures that mimic rainbows, the sun, and the moon may be added. For example, to create a rainbow, white light containing a wide range of wavelengths, such as a xenon lamp, is shone at an angle of 40-42° from the user's line of sight, matching the conditions under which rainbows occur in nature, allowing the user to see the rainbow. 【0106】 Additional effects can be obtained by adding active ingredients to the liquid that serves as the raw material for the fine particle group. For example, by using hypochlorous acid water as the raw material, a mist with disinfecting and deodorizing effects can be generated. Furthermore, aromatic components such as essential oils, or components that stimulate both taste and smell, such as those used in e-cigarettes, may also be used as raw materials. 【0107】 By using liquids containing nanobubbles, microbubbles, or non-toxic microorganisms as the raw material for the mist, the mist can be given functional properties. For example, a technology is known that incorporates ozone as nanobubbles to give the mist sustained sterilization properties. Furthermore, by incorporating photosynthetic microorganisms such as algae into the mist, it is expected that it will also have CO2 absorption and air purification capabilities. 【0108】 Instead of using ultrasonic vibrations as the energy source for atomizing the liquid, a technique can be used that generates mist by simultaneously spraying pressurized air and water from a nozzle. Alternatively, a technique can be used to create a large amount of mist by heating a liquid supplied from a tank (such as a mixture of ethylene glycol and water) and then discharging it while it cools. It is also possible to use dry ice or other methods to condense water vapor in the air into liquid droplets. 【0109】 Instead of infrared irradiation from the irradiation unit 30, thermal radiation from a resin mixed with far-infrared radiators such as a transparent film heater, carbon nanotubes, or silica may be used. By arranging thermal radiators in a wireframe shape to match the spatial area where artificial clouds are to be generated, and releasing fog into the inside of the wireframe structure, fog can be accumulated only in the area located inside the frame. 【0110】 Alternatively, suction ports can be provided at the desired locations on the wireframe structure to remove mist, allowing for removal by suction. Alternatively, instead of suction, dry air can be released only to the outer edges of the frame to remove the mist. Alternatively, a technique may be used to remove particle groups by applying a high voltage to electrodes to create a flow of charged particles. Alternatively, a voltage may be applied to a wireframe structure to remove charged particles. 【0111】 As for the structure of the drive unit 31 that moves the recognition unit 20 and the illumination unit 30, in addition to a pan-tilt type actuator, a robot hand or a motor control mechanism for linear and theta axes may also be used. Furthermore, the recognition unit 20 and the illumination unit 30 may be configured by arranging image recognition sensors and infrared irradiators in an array, and recognition and illumination of a predetermined position may be performed by operating the image recognition sensors and infrared irradiators at the corresponding positions, rather than by moving them. 【0112】 <Second Embodiment> Next, a second embodiment of the present invention will be described. The spatial arrangement control system 4 for a group of fine particles according to the second embodiment is used as a relaxation facility. Figure 10 is an external view of the spatial arrangement control system 4 for a group of fine particles according to the second embodiment of the present invention. As shown in Figure 10, the spatial arrangement control system 4 for the fine particle group has the fine particle group generation unit 10 positioned below the irradiation unit 30, and releases the mist, which is the fine particle group, so that it remains on the floor. 【0113】 Therefore, mist can be dispensed onto the feet of a user seated in a chair. By removing the fine particles near the user's feet using infrared irradiation, the diffusion of the fine particles can be stopped before they reach the user. Users can benefit from the warming and humidifying effects of infrared radiation, which promote health through improved metabolism and provide beauty benefits through moisturizing. Furthermore, the accumulated microparticles create a cloud-like appearance, offering visual benefits through observation. 【0114】 <Other uses> • Use as a humidifier / heater The steam and heat generated during the removal of particulate matter can be used as a humidifier or heater that creates an artificial cloud. By using infrared irradiation during the removal of particulate matter, a heat sterilization effect can also be achieved. 【0115】 • Use as an air purifier utilizing microorganisms By incorporating photosynthetic microorganisms such as algae into the microparticles, air purification capabilities can be achieved through carbon dioxide absorption and oxygen release. The microparticle form maximizes the surface area per unit volume of water, thereby maximizing gas exchange efficiency. 【0116】 • Use of artificial clouds as decoration for stages, etc. Artificial clouds can be used as part of the decoration at music concerts, amusement parks, and other similar events. For example, clouds could be draped over structures in an amusement park to create a more fantastical atmosphere. Artificial clouds can also be added as additional decoration to outdoor viewing activities, such as cherry blossoms during flower viewing. 【0117】 • Using clouds as a 3D projector The generated artificial clouds can be used as projectors to display advertisements and other images. Because it can generate denser clusters of particles in specific locations than existing technologies, it is possible to show users clearer images. 【0118】 • Use in games and attractions Artificial clouds can also be used as obstacles or other elements to enhance the gameplay in survival games. Because this invention allows for the generation of artificial clouds at any desired position and shape, it enables game-related effects such as obstructing the visibility of targets or creating changes in visibility over time as the cloud's position gradually shifts. 【0119】 Although embodiments of the present invention have been described in detail above, the scope of the present invention is not limited to the embodiments described above. Furthermore, the embodiments described above can be improved or modified in various ways without departing from the spirit of the present invention. In addition, the embodiments and modifications described above can be combined. 【0120】 The details described in each of the above embodiments are noted below. 【0121】 (Note 1) Applying external energy to a liquid or solid application The part includes a part generation unit that generates a group of fine particles, A spatial arrangement control system for a group of microparticles, comprising: an irradiation unit that irradiates the group of microparticles generated by the microparticle group generation unit with electromagnetic waves to remove a portion of the group of microparticles; and 【0122】 (Note 2) The irradiation unit irradiates the group of fine particles with infrared light as the electromagnetic wave.
