[0009] 1. First embodiment (odor presentation control system 500)

[0010] (1) Configuration example of odor presentation control system 500

[0011] 1 is a block diagram showing an example of an outline of an odor presentation control system 500. In this embodiment, the odor presentation control system 500 includes at least an information acquisition unit 501, a control unit 502, an odor presentation unit 503, a memory unit 504, an output unit 505, and a blower mechanism 506. If necessary, the system may also include other components such as an input unit 507 and a deodorizing mechanism. Each component of the odor presentation control system 500 according to this embodiment will be described below.

[0012] (2) Information acquisition unit 501

[0013] The information acquisition unit 501 acquires information related to a specific target. The "target" here is a broad concept that includes not only humans but also all kinds of animals and plants, such as dogs, cats, monkeys, rabbits, hamsters, mice, guinea pigs, horses, cows, pigs, chickens, parakeets, parrots, owls, horned owls, squirrels, flying squirrels, turtles, lizards, snakes, salamanders, other animals, ornamental fish, insects, and plants. Of these, humans and pet animals are particularly preferred as targets.

[0014] Furthermore, the specific target is not necessarily limited to one individual, but may be a plurality of individuals (groups). The specific target may be moving or stationary.

[0015] Specific examples of the information acquisition unit 501 include, for example, an environmental sensor, a vital sensor, a camera, a brightness sensor, an infrared sensor, an odor sensor, a gas sensor, etc., or one or more of these can be used in combination.

[0016] The information obtained from the various sensors described above is not particularly limited, and examples thereof include an environmental sensor that detects temperature, humidity, atmospheric pressure, and ultraviolet radiation; a vital sensor that detects vital signs such as pulse, blood pressure, respiration, and body temperature, as well as brain pressure, brain waves, the number of blinks, the amount of bleeding, the amount of sweat (including the amount of sweat during sleep), the amount of tears, the level of consciousness, the amount of excrement, facial expressions, and emotions (including cases where estimation is made based on information obtained from sensors); and a camera that detects race, sex, age, whether or not an object is present, the position of the object, the number of objects, the height of the object, and specific parts of the object (for example, the face, nose, hands, feet, back, etc.). The following information may be obtained: the position, facial expression, etc. of a person (e.g., inside a room, etc.); a brightness sensor measures the amount of indoor lighting, the amount of entrance lighting, etc.; an infrared sensor measures changes in outside temperature, room temperature, radiant temperature, perceived temperature, the position of a person, and the operating status of various devices (e.g., televisions, air conditioners, fans, circulators, air purifiers, humidifiers, commercial air conditioning systems, automatic doors, automatic toilet lids, non-contact thermometers, etc.); an odor sensor measures odors, etc.; a gas sensor measures nitrogen, oxygen, carbon monoxide, carbon dioxide, alcohol, fuel vapor gas, etc., or a combination of one or more of these. While only one type of information obtained from various sensors may be used, combining two or more types of information can more accurately present an odor that corresponds to a specific target. Note that each sensor may measure by directly contacting a specific target, or may measure non-contact. Recent technology has also included non-contact vital signs sensors, and this technology can also use such types of sensors.

[0017] The information acquisition unit 501 and / or the odor presentation unit 503 (described later) may be fixed in a desired position using a stand, clip, tripod, hanging mechanism, etc. These may be formed from a rod, a plate-like member, a shape-memory material, etc. Furthermore, when attaching to a ceiling, wall, etc., a magnet may be used, and in this case, it is preferable that a neodymium magnet is mounted on the information acquisition unit 501 or the odor presentation unit 503 side. Furthermore, the information acquisition unit 501 may be attached to the air blowing mechanism 506 of an air conditioner, electric fan, etc. using a cable tie, etc.

[0018] (3) Control unit 502

[0019] The control unit 502 is a part that determines the odor presentation conditions based on the information acquired by the information acquisition unit 501 and / or information prepared in advance. Examples of the information acquired by the information acquisition unit 501 include information obtained from the various sensors described above.

[0020] Examples of the information prepared in advance include information input or registered in advance by the user, weather forecast information, traffic congestion forecast information, etc. Examples of the information input or registered in advance by the user include gender, race, preferred scent presentation conditions, height, weight, current mood, current physical condition, average sleep time in a predetermined period (e.g., the most recent week), average number of bowel movements in a predetermined period, smoking history, drinking history, expected time of falling asleep or waking up, whether or not the user is pregnant or menstruating if female, and the like, or a combination of one or more of these, but the present technology is not particularly limited to such information.

[0021] The term "smell" as used herein includes any component that stimulates some or all of the receptors present in the nasal cavity, such as odor molecules. Furthermore, in addition to olfactory receptors, the nasal cavity also contains trigeminal receptors that control stimuli such as cold, hot, and painful sensations. The term "smell" as used herein is a broad concept that includes any component that stimulates some or all of these receptors. Specifically, for example, when menthol is used as a scent, it can stimulate via olfactory receptors and also stimulate a cooling sensation via trigeminal receptors (TRPA1 channels), and therefore is included in the term "smell."

[0022] The odor presentation conditions determined by the control unit 502 include, for example, the type of odor (including the use of one type or a mixture of two or more types), the amount of odor emitted, the strength of the odor (including concentration), the direction of odor emission, the degree of odor diffusion, the range of odor emission, the distance of odor emission, the location of odor emission, the duration of odor emission, the time period during which odor emission is stopped, the number of times odor emission is performed, the mixing ratio of each fragrance in the case of a mixture of two or more types of odor, and the like, or a combination of one or more of these conditions, but are not particularly limited in the present technology. Furthermore, when multiple odor-generating cartridges 1 are provided, the control unit 502 may determine the same emission conditions for each odor-generating cartridge 1, or may determine emission conditions for each odor-generating cartridge 1. The odor-generating cartridge 1 will be described in "(4) Odor Presentation Unit 503."

[0023] The control unit 502 may evaluate the state of the specific target after the odor is presented. The "state" here includes not only one or more pieces of information acquired from the information acquisition unit 501, but also information inferred from the acquired one or more pieces of information. Specifically, for example, if the pulse rate decreases after the odor is presented, the target to whom the odor is presented may be evaluated as being calm. On the other hand, if the pulse rate increases, the target to whom the odor is presented may be evaluated as being excited. Furthermore, in this embodiment, the control unit 502 may perform feedback control regarding the odor presentation conditions based on the results of the evaluation.

[0024] In this case, the control unit 502 can set a desired environment based on the results of the evaluation. The term "setting" here includes both manual and automatic settings, and also includes settings that are manual or automatic up to a certain point and then automatic or manual thereafter. Specifically, for example, if a specific subject wants to create a relaxing environment, the control unit 502 can set the desired environment by changing the scent presentation conditions based on the results of the evaluation. Furthermore, if the specific subject wants to create an environment in which they can concentrate, the control unit 502 can set the desired environment by changing the scent presentation conditions based on instructions from the specific subject and the results of the evaluation.

[0025] The control unit 502 may have, for example, an internal control unit 5021 that controls the information acquisition unit 501, the odor presentation unit 503, and the blower mechanism 506, and an external control unit 5022 that can communicate with the internal control unit 5021 via a wired or wireless (e.g., Wi-Fi, Bluetooth, etc.) network. In this case, the odor presentation conditions are determined by the internal control unit 5021 and / or the external control unit 5022, but by using both the internal control unit 5021 and the external control unit 5022 in combination, it is possible to present an odor to a specific target with greater accuracy. Furthermore, the control unit 502 may be able to communicate with each component of the odor presentation control system 500 via a wired or wireless network.

[0026] Examples of the external control unit 5022 include, but are not limited to, an application (application software) stored in a smartphone, a tablet terminal, a wearable terminal, a smart speaker, a personal computer, etc. Examples of the application include a native application, a web application, a hybrid application, and an embedded application.

[0027] The external control unit 5022 may also include a storage unit 504 and / or an output unit 505, which will be described later. The external control unit 5022 may also include an input unit 507 that receives instructions from the user.

[0028] (4) Odor presentation unit 503

[0029] The odor presentation unit 503 is a part that presents an odor based on the odor presentation conditions determined by the control unit 502. A specific example of the odor presentation unit 503 includes an odor generating cartridge 1, an odor control unit 532, and an odor emission hole 533.

[0030] Figure 2 is a perspective view showing an example of an embodiment of the odor presentation unit 503. Figure 3 is a six-sided view showing the embodiment shown in Figure 2, where A is a front view, B is a rear view, C is a left side view, D is a right side view, E is a plan view, and F is a bottom view. Figure 4 is a perspective view showing an example of the structure inside the housing of the odor presentation unit 503. The odor generating cartridge 1 and the odor control unit 532 are located inside the housing of the odor presentation unit 503, as shown in Figure 4.

[0031] In this embodiment, the odor presentation unit 503 has a substantially rectangular cylindrical shape as shown in Figures 2 and 3. However, the shape of the odor presentation unit 503 is not particularly limited, and may be a substantially polygonal cylindrical shape such as a substantially cylindrical, elliptical, triangular, or square cylindrical shape (including those with rounded corners), a substantially conical shape, or a substantially polygonal pyramid with a cross section such as a substantially triangular or square shape (including those with rounded corners), or a shape that freely combines one or more of these shapes. Furthermore, for example, the odor presentation unit 503 may have a shape that combines substantially cylindrical shapes with different diameters. Each part of the odor presentation unit 503 will be described below.

[0032] <First Embodiment of Odor Generating Cartridge 1> A first embodiment of the odor generating cartridge 1 will now be described. Figure 5 is a schematic cross-sectional view showing the first embodiment of the odor generating cartridge 1. In this embodiment, the odor generating cartridge 1 at least comprises an odor retaining section 11 that retains an odor, a ventilation section 12 that takes in air, a flow section 13 that communicates with the ventilation section 12 and has at least one spiral flow path 131, and a discharge section 14 that communicates with the flow section 13 and discharges odor-containing air. Furthermore, although not shown, the cartridge may also comprise an information display section, a pump direct drive mechanism, etc., as needed.

[0033] The material for forming the housing 10 of the odor generating cartridge 1 is not particularly limited, and examples thereof include metals such as stainless steel (SUS (Steel Use Stainless)) and aluminum; resins such as polyvinyl chloride, polyethylene, phenolic resin, olefin resin, acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, and polyimide resin; pottery; porcelain; ceramic; or any combination of one or more of these.

[0034] 5, the shape of the odor generating cartridge 1 is not particularly limited as long as there is space inside to store at least the odor retention section 11 and the flow section 13, and the shape can be a substantially cylindrical shape, a substantially polygonal cylindrical shape such as a substantially elliptical cylindrical shape, a substantially triangular cylindrical shape, a substantially square cylindrical shape (including shapes with rounded corners), a substantially conical shape, a substantially polygonal pyramid shape with a cross section such as a substantially triangular or substantially square shape (including shapes with rounded corners), or a shape that is a free combination of one or more of these. Each part of the odor generating cartridge 1 according to this embodiment will now be described.

[0035] [Odor Retention Section 11] The odor retention section 11 is a section that retains an odor. Specifically, there are no particular limitations on the odor retention section 11 as long as it can retain an odor, but for example, it can be an impregnated material 20 impregnated with a component that can generate an odor.

[0036] The material for forming the impregnating material 20 is not particularly limited, and may be, for example, an organic polymer material to facilitate odor penetration. Examples of organic polymer materials include polyvinyl chloride, polyethylene, phenolic resin, olefin resin, nylon, polyester, synthetic rubber, silicone resin, natural rubber, proteins, nucleic acids, lipids, polysaccharides, etc., or any combination of one or more of these. Other examples include polymer resins such as acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, and polyimide resin; metals such as stainless steel (SUS (Steel Use Stainless)) and aluminum; inorganic crystals such as quartz; glass; filter paper; and any combination of one or more of these.

[0037] The impregnating material 20 may also be formed to be porous, and for example, a mesh structure, cork, mesoporous silica, calcium carbonate, etc. Furthermore, the impregnating material 20 may also be formed to have a fibrous structure or a layered structure (for example, clay minerals, etc.).

[0038] The form of the impregnating material 20 is not particularly limited, and may be, for example, a sheet, a mesh, a strip (including a dense body thereof), a particle (including a dense body thereof), a gel, a liquid (including a liquid maintained by the surface tension of a holder or the like), a foam, a three-dimensional structure (for example, a pinholder, a spiral, a spring, etc.), a string (including a dense body thereof), or a form in which one or more of these are freely combined.

[0039] In this embodiment, as shown in Figure 5, the impregnating material 20 is in sheet form and is rolled into a substantially cylindrical shape and stored inside the cylindrical odor generating cartridge 1. By making the impregnating material 20 in sheet form, it becomes easier to store it in the cylindrical odor generating cartridge 1, improving production efficiency. Note that while Figure 5 shows the sheet-like impregnating material 20 as having a single layer structure, it is also possible to store it in the odor generating cartridge 1 in multiple layers, as needed.

[0040] The scent to be retained in the impregnated material 20 is not particularly limited as long as it is a component that can generate a scent (hereinafter also referred to as "fragrance"). Specifically, liquid fragrance, powder fragrance, etc., either as is or dissolved or dispersed in an appropriate solvent, essential oil, essential oil diluted with an appropriate solvent, fruit juice, food or drink, or dissolved or dispersed in an appropriate solvent, or any combination of one or more of these can be used.

[0041] The impregnating material 20 may contain components other than the component capable of generating an odor, such as a component that produces a pharmacological effect when inhaled. Furthermore, if the only purpose is to produce a pharmacological effect, the impregnating material 20 may be impregnated only with a component that produces a pharmacological effect when inhaled, rather than with a component that can generate an odor.

[0042] Furthermore, if necessary, odorless air may be discharged using the mechanism of the odor generating cartridge 1 without retaining any component capable of generating an odor in the impregnating material 20. Alternatively, only the operation of the odor generating cartridge 1 may be turned OFF, and only the operation of the air blowing mechanism 506 (described later) may be turned ON, generating only auxiliary air from the air blowing mechanism 506. Furthermore, in this case, only the odorless air or auxiliary air can be used for applications such as an air curtain.

[0043] [Ventilation section 12] The ventilation section 12 is a section that takes in air. The air is basically the outside air around the odor generating cartridge 1, but it may also be air collected from a specific location or air containing a specific substance.

[0044] There are various methods for taking in air into the ventilation section 12. For example, although not shown, air can be taken in by directly moving a component such as a pump that abuts against a part of the flow section 13 through the ventilation section 12.

[0045] Note that components such as a pump and their movable sources may be integrated with the odor generating cartridge 1 (may be formed in the same housing), or may be formed separately and used in combination with the odor generating cartridge 1 before linear movement. Also, the odor generating cartridge 1 integrated with components such as a pump and their movable sources may be distributed, or the components such as a pump and their movable sources formed separately may be distributed independently.

[0046] To take in air by directly moving the pump unit, the pump unit is directly moved relative to the odor generating cartridge 1, and in the embodiment shown in Figure 5, the pump unit is used to press a part of the flow section 13, allowing outside air to be taken in through the ventilation section 12. In the past, the pump unit was fixed and a separate plunger was moved, but in this technology, air flows efficiently and there is no need to provide a separate component such as a plunger, so that fewer parts are required and a compact opening and closing mechanism can be provided.

[0047] The moving source for linearly moving the pump section is not particularly limited as long as it can move the pump section in the linear direction, and examples include shape memory alloys (SMA), motors, solenoids, linear slide types, pneumatic (air pump types), actuators equipped with small electromagnets, etc. Note that "linearly moving" as used here does not only include cases where one member moves in a linear direction, but also cases where some members of a group of multiple connected members move in a linear direction.

[0048] In addition, in the present technology, the axial flow from the blower mechanism 506 may be used as the driving source of the pump unit.

[0049] [Flow passage portion 13] The flow passage portion 13 is a portion that communicates with the ventilation portion 12 and has at least one or more spiral flow passages 131. By having the spiral flow passage 131, it is possible to utilize rolling, a method for manufacturing screws and the like, and improve manufacturability. Furthermore, since the flow passage portion 13 can be metallized, it can be formed from a material that is highly resistant to chemicals and / or has low gas permeability. Examples of materials that are highly resistant to chemicals and / or have low gas permeability include metals such as stainless steel (SUS (Steel Use Stainless)) and aluminum; glass, etc., but the present technology is not particularly limited thereto.

[0050] In this embodiment, it is preferable that a part or all of the odor retention unit 11 abuts against the spiral flow path 131. This increases the contact area between the odor retention unit 11 and the air flowing through the spiral flow path 131, allowing for efficient odor impartation. Furthermore, by providing two or more spiral flow paths 131, the contact area between the odor retention unit 11 and the air flowing through the spiral flow path 131 can be further increased. This makes it possible to generate odor-containing air even in a relatively short spiral flow path 131, allowing for the overall dimensions of the odor generating cartridge 1 to be reduced.

[0051] In this embodiment, the flow conduit 13 may include a shaft 130 that pushes up a discharge part lid 141, which will be described later. In this case, a return spring 132 may be provided to return the flow conduit 13 to its original position after being pushed up.

[0052] [Discharge section 14] The discharge section 14 is a section that communicates with the flow section 13 and discharges odor-containing air. Note that the term "outside" as used herein also includes concepts such as a specific space or a specific place.

[0053] The discharge part 14 is equipped with a discharge part lid 141 and a discharge part spring 142 to prevent odor leakage. Opening the discharge part lid 141 discharges odor-containing air outside the odor-generating cartridge 1. That is, after outside air flows in through the ventilation part 12 due to the linear motion of the pump part abutting a part of the flow part 13, the air flows through the flow part 13 and comes into contact with the odor retention part 11, forming odor-containing air. The odor-containing air is then released from the discharge part lid 141, which is pushed up by the shaft 130, and discharged to the outside via the discharge part 14. Thereafter, the restoring forces of the return spring 132 and the discharge part spring 142 return the flow part 13 and the discharge part lid 141 to their original positions, closing the ventilation part 12.

[0054] [Others] The odor-generating cartridge 1 according to this embodiment may further include an information display unit. While not a required component of the present technology, the information display unit is provided on a portion of the outer circumferential surface of the odor-generating cartridge 1, and is a portion from which information about the odor-generating cartridge 1 can be acquired. By including the information display unit, information related to the odor-generating cartridge 1 can be acquired, leading to improved usability. The information display unit is not particularly limited, and examples thereof include pattern images such as one-dimensional codes and two-dimensional codes; markers or LED lights formed in one or more colors; or a combination of one or more of these. The information display unit may be read by, for example, a camera, a barcode reader, or the like, or may be visually determined by a human. Note that markers or LED lights formed in one or more colors may be used simply for decorative purposes.

[0055] Examples of information contained in the information display unit include, but are not limited to, the type of odor and remaining amount of odor in the odor-generating cartridge 1, the names of ingredients that can generate the odor and allergen information for those ingredients, the expiration date and number of uses of the odor-generating cartridge 1, the date and place of manufacture, and the version (Ver.) information for the odor-generating cartridge 1. Note that, if a portion of the outer peripheral surface has curvature, it is preferable that the information display unit be printed or affixed to a portion of the outer peripheral surface to the extent that it can be read by the camera or barcode described above. In this case, the information display unit, which is a pattern image, may be printed onto a portion of the outer peripheral surface by projection.

[0056] Furthermore, the information display unit may be linked to an application, and information acquired via the application may be displayed on a screen of a smartphone, a wearable device, a tablet device, a computer, a game console, etc. In this case, by utilizing the application, a user may add additional information to the acquired information, such as whether or not the scent is pleasant, and the additional information acquired from one or more users may be accumulated on a server or cloud and utilized for machine learning, etc.

[0057] <Second Embodiment of Odor Generating Cartridge 1> A second embodiment of the odor generating cartridge 1 will now be described. Fig. 6 is a six-view diagram showing the second embodiment of the odor generating cartridge 1, where A is a front view, B is a rear view, C is a left side view, D is a right side view, E is a plan view, and F is a bottom view. Fig. 7 is a perspective view showing the second embodiment of the odor generating cartridge 1, and Fig. 8 is a cross-sectional view taken along line P-P of the embodiment shown in Fig. 7. The odor generating cartridge 1 according to this modification at least comprises an odor retention section 101, a ventilation section 102, and a connecting section 103.

[0058] 8, the odor retention unit 101 includes at least an impregnating material 20 and a container 21. In this embodiment, the lid 22 corresponding to the container 21 is joined to a part of the connecting unit 103, which will be described later. Note that in this embodiment, the joining also includes a case in which the connecting unit 103 and the lid 22 are formed as a single molded part.

[0059] The material forming the impregnating material 20 and the form of the impregnating material 20 are not particularly limited and are the same as those described in the first embodiment, so a description thereof will be omitted here. The scent retained in the impregnating material 20 is also not particularly limited and is the same as those described in the first embodiment, so a description thereof will be omitted here.

[0060] The container 21 preferably has a two-layer structure, and in this embodiment, as shown in FIG. 8 , it is composed of an inner layer 211 that forms the inside of the container 21 and holds the impregnating material 20, and an outer layer 212 that forms the outside of the container 21. The material for forming the inner layer 211 is not particularly limited, but in this embodiment, it is preferable that part or all of the inner layer 211 be formed from glass or metal. Examples of metal include stainless steel (SUS (Steel Use Stainless)) and aluminum. In this embodiment, the inner wall of the inner layer 211 on the impregnating material 20 side may be formed from metal foil or may be metal-plated.

[0061] [Ventilation Section 102] The ventilation section 102 includes an openable / closable ventilation opening 30. In the present embodiment, the ventilation section 102 is configured to be divided into two sections (first ventilation section 102a and second ventilation section 102b) by the two ventilation openings 30 as shown in FIG. 8 . However, this is not particularly limited in the present technology, and the ventilation section 102 may be configured as a single section, or may be configured as being divided into, for example, three or more sections. That is, in the present embodiment, as shown in FIG. 8 , the ventilation opening 30 includes an inlet ventilation opening 30a for allowing air to flow into the odor generating cartridge 1 and an outlet ventilation opening 30b for releasing the odor-containing air to the outside. An opening / closing mechanism is provided in connection with these two ventilation openings 30 (30a, 30b). The specific structure of the opening / closing mechanism is not particularly limited as long as it can open and close the two ventilation openings 30 (30a, 30b), and can be freely designed. Specifically, as shown in FIG. 9 described later, an opening and closing mechanism may be provided that is made up of a sealing lid 1021 (1021a, 1021b), a shaft 1022, and a spring 1023 (1023a, 1023b).

[0062] In this embodiment, the ventilation section 102 preferably has a two-layer structure, and in this embodiment, as shown in Figure 8, it consists of an inner layer member 31 that houses the opening and closing mechanism and an outer layer member 32 that forms the outside of the ventilation section 102.

[0063] [Connecting portion 103] The connecting portion 103 comprises at least two connecting openings 40 (40a, 40b) formed in the lid portion 22 joined to the connecting portion 103, which connect the ventilation portion 102 and the odor retention portion 101, and a partition portion 41 arranged upstream of one of the at least two connecting openings 40 (40a, 40b). In this embodiment, the two connecting openings 40 (40a, 40b) comprise a first connecting opening 40a that releases air from the connecting portion 103 to the odor retention portion 101, and a second connecting opening 40b that releases odor-containing air from the odor retention portion 101 to the connecting portion 103, as shown in Figure 8. In this case, the air that flows into the connecting part 103 through the first ventilation part 102a is released into the odor retention part 101 through the first connecting opening 40a, where it mixes with the odor, and then the odor-containing air flows into the connecting part 103 through the second connecting opening 40b and is released to the outside through the second ventilation part 102b.

[0064] In this embodiment, the partition 41 is disposed upstream of the second connecting opening 40b of the two connecting openings 40 (40a, 40b). By providing the partition 41, air that flows into the connecting portion 103 is forced to pass through the odor retention portion 101 to become odor-containing air, and then flows back into the connecting portion 103. In this embodiment, the connecting portion 103 is also provided with an opening / closing mechanism in the connection area with the ventilation portion 102.

[0065] [Example of Operation of Discharging Odor-Laden Air] Figure 9 is a cross-sectional view showing how an odor is discharged from the odor generating cartridge 1 of the embodiment shown in Figure 7. In this embodiment, when the ventilation section 102 is opened while the odor is retained in the odor retention section 101, air flows in from the outside. The inflowing air flows into the connecting section 103 and passes through one connecting opening 40a, sending an airflow to the odor, scenting it as the airflow passes near the impregnating material 20, and releasing the odor-laden air. In this state, the released odor-laden air flows into the connecting section 103 through the other connecting opening 40b, and is released to the outside.

[0066] Specifically, in this embodiment, the ventilation openings 30 (30a, 30b) and the connecting portion 103 are provided with opening / closing mechanisms each consisting of a sealing lid, a shaft, and a spring. These opening / closing mechanisms can be controlled, for example, by inserting a plunger from the first sealing lid 1021a side and connecting it to the shaft, as shown in FIG. 9 . That is, when the plunger is pressed, it pushes the first sealing lid 1021a toward the inside of the first ventilation portion 102a, opening the inlet ventilation opening 30a and allowing air to flow into the first ventilation portion 102a. At this time, the first spring 1023a is compressed by the first sealing lid 1021a.

[0067] As the first sealing lid 1021a is pushed inward toward the first ventilation portion 102a, the shaft 1022 attached to the first sealing lid 1021a moves toward the connecting portion 103. This shaft 1022 pushes the sealing lid 1031 inward toward the connecting portion 103, causing air in the first ventilation portion 102a to flow into the connecting portion 103. At this time, the spring 1033 is compressed by the sealing lid 1031. Due to the partition 41, the air flowing into the connecting portion 103 first flows into the odor retention portion 101 through the first connecting opening 40a provided in the lid portion 22 and sends the airflow to the odor retained in the odor retention portion 101. As a result, the airflow is scented as it passes around the impregnating material 20, releasing odor-containing air. This odor-containing air then flows back into the connecting portion 103 through the second connecting opening 40b provided in the lid portion 22.

[0068] When the sealing lid 1031 is pushed inward into the connecting portion 103, the shaft 1032 attached to the sealing lid 1031 moves toward the second vent portion 102b. This shaft 1032 pushes the second sealing lid 1021b inward into the second vent portion 102b, causing the odor-containing air in the connecting portion 103 to flow into the second vent portion 102b. At this time, the second spring 1023b is compressed by the second sealing lid 1021b. In this embodiment, since the second vent portion 102b is connected to the release vent opening 30b, the odor-containing air that has flowed into the second vent portion 102b is released to the outside through the release vent opening 30b. After the odor-containing air has been released to the outside, the pressure on the plunger is released, and the restoring force of the compressed first spring 1023a returns the first sealing lid 1021a to its original position. The sealing lid 1031 is returned to its original position by the restoring force of the spring 1033, and the second sealing lid 1021b is returned to its original position by the restoring force of the second spring 1023b.

[0069] To drive the plunger, as shown in FIG. 4 , an SMA sliding section X1 that folds and slides the shape memory alloy SMA is provided near the tip of the plunger, and the shaft and the movable source X2 are fixed so that the plunger is positioned to connect to the shaft of the odor generating cartridge 1. A power supply wiring is connected to the movable source X2, and power may be supplied via the wiring from a battery (including a storage battery) or a power source. The plunger can move in the extension direction within the housing of the odor presentation unit 503 by the expansion and contraction of the shape memory alloy SMA. For example, the shape memory alloy SMA is folded back into a U-shape at the SMA sliding section X1 provided near the tip of the plunger, passes through the plunger, and both ends are fixed at the rear end of the plunger. In this embodiment, the actuator is not limited to a shape memory alloy SMA, and may be any linear motion mechanism that linearly moves the plunger, such as a motor, solenoid, linear slide type, pneumatic (air pump type), or small electromagnet.

[0070] [Odor control unit 532] The odor control unit 532 is a unit that controls the odor presentation unit 503 based on instructions from the control unit 502. The installation location of the odor control unit 532 is not particularly limited, and may be installed, for example, inside the housing of the odor presentation unit 503.

[0071] The odor control unit 532 controls the odor presentation unit 503 based on the odor presentation conditions determined by the control unit 502 so that the presentation conditions are realized. Specifically, the emission conditions can be realized by, for example, replacing the odor-generating cartridge 1, mixing the odor-containing air from two or more odor-generating cartridges 1 in a desired ratio, controlling the amount and speed of the odor-containing air emitted, the concentration of the fragrance in the odor-generating cartridge 1 used, the number of times the odor-containing air is emitted, the emission time, and the emission stop time, or by controlling one or more of these in combination. Furthermore, the odor control unit 532 can also contribute to the realization of the presentation conditions by controlling, as necessary, the direct movement of the pump unit attached to the odor-generating cartridge 1 and the deodorizing mechanism described below.

[0072] Furthermore, the odor presentation unit 503 may be composed of one or more odor presentation units 503, and if it is composed of two or more odor presentation units 503, two or more odor presentation units 503 can be placed side by side using a joining mechanism (e.g., engagement using a concave-convex shape; engagement using a claw, pin, hook, clamp, etc.; engagement using an adhesive with adhesive properties that allow for removal and attachment; sliding engagement, etc.) provided on the side of the housing of the odor presentation unit 503.

[0073] (5) Storage unit 504

[0074] The storage unit 504 is a component that stores information acquired by the information acquisition unit 501 and / or information prepared in advance. The storage unit 504 also stores various information, such as the results of evaluation by the control unit 502 and desired environmental conditions set by the control unit 502. The storage unit 504 may be located within the housing of the control unit 502, or may be connected to an external control device or the like via a network and installed on a server or cloud. In this case, each user can share various information stored in the storage unit 504 on the cloud via the network. In consideration of users' personal information, some information may be viewable only by those with viewing authority.

[0075] The storage unit 504 may also perform machine learning using AI based on all stored information. As a result, a scent appropriate for a specific target can be presented to the specific target with higher accuracy. Furthermore, the machine learning may be performed on the cloud, in which case each user can share the results of the machine learning stored on the cloud via a network.

[0076] The control unit 502 may determine the odor presentation conditions based on information stored in the storage unit 504. Specifically, examples of such information include a history of ejection conditions previously set for a user, odor presentation conditions previously evaluated by the user, reactions previously shown by the user (e.g., vital data), odor presentation conditions accumulated on the cloud, odor presentation conditions based on knowledge obtained by machine learning, or a combination of one or more of these, but the present technology is not particularly limited thereto.

[0077] The storage unit 504 may be located within the housing of the control unit 502, but may also store various pieces of information using one or more types of external storage devices.

[0078] (6) Output unit 505

[0079] The output unit 505 outputs information acquired by the information acquisition unit 501 and / or information prepared in advance. The output unit 505 also outputs all kinds of information, such as the results of evaluation by the control unit 502 and desired environmental conditions set by the control unit 502. Specific examples of the output unit 505 include visual displays on monitors, screens of mobile information terminals, control devices used for entertainment purposes, etc.; audio outputs from speakers, earphones, headphones, microphones, etc.; tactile outputs such as deformation of components, changes in the arrangement of components, temperature changes such as cold or warm components, and stimulation by weak currents, or combinations of one or more of these, but are not particularly limited in the present technology.

[0080] The output unit 505 may be located within the housing of the control unit 502, or may output various information using one or more types of external output devices, etc. Furthermore, the output unit 505 may not only be owned by the user himself / herself, but also by the user's family, a medical institution, an emergency transport facility, etc.

[0081] (7) Blower mechanism 506

[0082] The air blowing mechanism 506 is a part that assists in blowing the odor-containing air emitted from the odor presentation unit 503. Specifically, by blowing auxiliary air generated using the air blowing structure, an airflow containing the odor-containing air discharged from the odor presentation unit 503 is formed, and the air blowing control unit controls to adjust and assist the odor presentation conditions, and the auxiliary air controlled by the air blowing control unit is released from the air blowing presentation unit.

[0083] Additionally, the airflow presentation unit may have a direction control unit such as a louver or a flap that controls the direction of the auxiliary air (e.g., left-right, up-down, left-right, up-down, etc.). Therefore, by providing the airflow mechanism 506, the determined odor presentation conditions can be realized more accurately. The airflow mechanism 506 may also be used to reduce the odor if a specific subject perceives the presented odor as too strong.

[0084] The air blowing mechanism 506 may be integrated with the odor presentation unit 503 or may be provided outside the odor presentation unit 503. The air blowing source is not particularly limited and may be, for example, an axial fan, a blower fan, a centrifugal fan, or a combination of one or more of these. The air blowing source may also be a diaphragm pump, or a combination of a diaphragm pump using a piezoelectric element or a motor (e.g., a microblower) and an airflow expansion mechanism.

[0085] Furthermore, air conditioners, electric fans, circulators, air purifiers, humidifiers, commercial air conditioning systems 2001; small fans, small air conditioners (mini coolers), and various other small devices used for tabletop, hanging, or bedside applications may be employed, and the scent presentation unit 503 may be attached to a portion of the housing of these devices as needed. In this case, the above-mentioned air conditioners may be used as the airflow expansion mechanism. In the present technology, it is particularly preferable to use an air conditioner as the blower mechanism 506. Air conditioners include types that only have a blowing function for heating and cooling, as well as types that have a blowing function that is driven separately from the blowing function for heating and cooling. While the present technology can be applied to any type of air conditioner, it is preferable to apply it to types that have a blowing function that is driven separately from the blowing function for heating and cooling.

[0086] Furthermore, if the fan of the air blowing source is made larger, it is possible to deliver gas containing odor-containing air over a long distance. In this way, it is possible to control the range over which the odor reaches by changing the size and number of fans, the range of motion of the direction control unit, etc. Therefore, the air blowing mechanism 506 is not provided in advance, and auxiliary air may be generated using one or more types of air blowing mechanisms 506, air blowing sources, and direction control units that are independently developed as needed.

[0087] (8) Input unit 507

[0088] The input unit 507 is a unit through which the user inputs information to each unit of the odor presentation control system 500. Specific examples include a keyboard, a smartphone, a tablet terminal, a wearable terminal, and a voice input device, but the present technology is not particularly limited to such a unit. Furthermore, the user may input the previously prepared information via the input unit 507.

[0089] The input unit 507 may be a keyboard or the like attached to the housing of the control unit 502, or various information may be input using one or more types of external input devices (i.e., a smartphone, a tablet terminal, a wearable terminal, a voice input device, etc.) connected wirelessly or via a wire.

[0090] (9) Other

[0091] The odor presentation control system 500 may include a warning unit (not shown) that issues a warning when, for example, information indicating a significant decline in the vital signs of a specific target is obtained as a result of information acquired by the information acquisition unit 501. The warning unit may be connected to other parts of the odor presentation control system 500 via a wired or wireless connection. In this case, the odor presentation control system 500 may be used to provide first aid to the specific target whose vital signs have declined, such as by emitting a strong odor or spraying a pharmacological gas. The warning unit may also automatically output current information about the specific target to the user's family, a medical institution, an emergency transport facility, etc. via the output unit 505.

[0092] Furthermore, the odor presentation control system 500 may, if necessary, include a reading unit that reads information from an information display unit included in the odor generating cartridge 1. Examples of the reading unit include a camera, a barcode reader, etc. In the present technology, the reading unit is not an essential component, and information may be read from the information display unit using the information acquisition unit 501 described above.

[0093] Furthermore, the odor presentation control system 500 may include a deodorizing mechanism as needed. The deodorizing mechanism includes a front member and a rear member, and has at least a deodorizing material portion between the front member and the rear member. Furthermore, it may include an air source as needed. The deodorizing mechanism may be used to reduce the odor when a specific subject perceives the presented odor as too strong.

[0094] The material for forming the front member is not particularly limited, and examples thereof include glass; metals such as stainless steel (SUS (Steel Use Stainless)) and aluminum; and resins such as polycarbonate, polyvinyl chloride, polyethylene, phenolic resin, olefin resin, acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, and polyimide resin, or any combination of two or more of these. The shape of the front member is also not particularly limited as long as it can accommodate the deodorizing material portion described below. For example, the shape may be a substantially polygonal shape such as a substantially triangular prism or a substantially square prism, a substantially cylindrical shape, a substantially elliptical cylinder, or any combination of two or more of these. Furthermore, if the front member is a substantially polygonal shape, the corners may be rounded, or a portion of the front member may be tapered or stepped.

[0095] The front member has a deodorizing material portion therein. The deodorizing material portion is not particularly limited, and may be, for example, a gas adsorbing substance woven or kneaded into the material, packed in a bag made of a gas-permeable material, or various fibers or structures themselves having a gas adsorbing structure, or may be a filter structure. Examples of gas adsorbing materials include activated carbon (e.g., palm, fir, bamboo, resin, wood, fiber, coal, etc.), zeolite, layered compounds (e.g., sheet silicate, alumina, etc.), porous silica (including mesoporous silica), etc., or any combination of one or more of these. The shape of the deodorizing material portion is also not particularly limited, and may be, for example, powder, granules, fiber, molded product, sheet (e.g., nonwoven fabric, woven fabric, etc.), rod-shaped, plate-shaped, etc. Furthermore, the surface of the deodorizing material portion may be subjected to, with or without activation treatment, for example, surface functional group exposure treatment (e.g., acidification, alkalinization, polarization, depolarization, etc.).

[0096] The upper and / or lower surfaces of the deodorizing material part may have one or more fall prevention parts for preventing the deodorizing material part from falling. The fall prevention parts are not particularly limited as long as they can prevent the deodorizing material part from falling, and can be formed, for example, in a sheet-like shape, with a mesh structure, a filter structure, etc. The fall prevention parts can be attached to the deodorizing material part using, for example, an adhesive, and it is preferable that they be attached so that no gaps are formed.

[0097] The material and shape of the rear member are not particularly limited and are similar to those of the front member described above, so further description will be omitted here. The rear member has an air blower therein. The air blower is not particularly limited, and examples thereof include an axial fan, a blower fan, and a centrifugal fan. Alternatively, the air blower may be a diaphragm pump, particularly a diaphragm pump using a piezoelectric element or a motor (e.g., a microblower). In this case, the rear member preferably has a groove or the like through which a harness or the like connecting the air blower to an external moving source (e.g., a piezoelectric element, a motor, etc.) can be routed so that the air blower can obtain energy from the external moving source.

[0098] The underside of the blower unit may have one or more blower unit fixing parts for fixing the blower unit. The blower unit fixing part is not particularly limited as long as it can fix the blower unit, and can be formed, for example, from a sheet-like adhesive, double-sided tape, etc. It is preferable that the blower unit fixing part is attached so that no gaps are created when attached. Furthermore, one or more attachment parts for attaching the deodorizing mechanism to another article, a housing, etc. may be formed on the surface of the rear member itself that does not fit with the front member. The attachment part is not particularly limited as long as it can fix the deodorizing mechanism, and can be formed, for example, from a sheet-like adhesive, double-sided tape, etc.

[0099] The rear member preferably has a mating groove formed therein. When mating with the front member, adhesive is applied to the mating groove, and the front member is inserted into the mating groove of the rear member to matingly connect the two. At this time, a harness connecting the blower unit to an external movable source is left out of the groove formed in the rear member. Furthermore, the adhesive or the like can completely eliminate any gaps, thereby sealing the front member and the rear member. In this embodiment, the mating groove is not an essential component, and the front member and the rear member may be sealed using an O-ring, screw fastening, or the like.

[0100] (10) Example of Operation Flow of the Odor Presentation Control System 500

[0101] FIG. 10 is a flowchart showing an example of the operation flow of the odor presentation control system 500. In the odor presentation control system 500, first, sensing is performed using the information acquisition unit 501 to acquire information about a specific target (S101). Specifically, for example, pulse rate is measured using a vital sensor, and changes in air temperature, room temperature, radiant temperature, perceived temperature, and human position are measured using an infrared sensor, and this information is used in combination. Note that, as described above, the information referred to here can also include information prepared in advance. Next, based on the acquired information, the control unit 502 determines odor presentation conditions (S102).

[0102] Here, the control unit 502 can estimate the state of the person from the acquired information and present an odor according to the estimated mode. For example, if the state of the subject is estimated to be working mode, a mood-boosting odor can be presented when brain activity levels drop, or a different odor can be presented to change the mood if the subject has been in the room for a long time. Also, if the state of the subject is estimated to be relaxation mode, a calming odor can be presented if the subject does not seem relaxed, or an odor suitable for sleep can be presented if it is detected that the subject has fallen asleep.

[0103] Although not shown, it is also possible for the control unit 502 to select a desired mood of a specific subject (e.g., wanting to calm down, wanting to concentrate, wanting to get excited, wanting to feel daydreamed, etc.) and determine the odor presentation conditions using information from the information acquisition unit 501. For example, if the subject selects that they want to calm down, and the control unit 502 determines that they are in an excited state based on their pulse rate, it is possible to change the odor presentation conditions in order to change the state of the specific subject from an excited state to a calm state, or to present the odor that the subject most likes based on knowledge obtained through machine learning using AI.

[0104] Next, the presentation unit 503 presents an odor based on the determined presentation conditions (S103). At this time, the blower mechanism 506 may generate auxiliary airflow, for example, by sending an airflow containing odor-containing air toward the position of the person sensed by an infrared sensor. Next, after a certain period of time has elapsed since the odor presentation, the information acquisition unit 501 performs sensing again to acquire information about the specific target (S104). Based on the acquired information, the control unit 502 evaluates whether the desired odor presentation conditions have been achieved (S105). The specific target may also input the evaluation themselves via the input unit 507.

[0105] For example, in working mode, the control unit 502 evaluates whether brain activity is increasing based on the pulse rate, and if it determines that brain activity is increasing, stops the odor presentation from the odor presentation unit 503 (S106). On the other hand, if the control unit 502 determines that brain activity is not increasing, the process returns to S102. The subsequent flow from S103 onwards is as described above.

[0106] If the subject is in the relaxation mode, the control unit 502 evaluates whether the subject is calm based on the pulse rate, and if it determines that the subject is calm, stops the odor presentation from the odor presentation unit 503 (S106). On the other hand, if it determines that the subject is not calm, the process returns to S102. The subsequent flow from S103 onwards is as described above.

[0107] (11) Example of replacement of odor generating cartridge 1

[0108] 11 is a schematic overhead view of a replacement module A for an odor-emitting cartridge 1. The replacement module A includes at least a collection space A1 for collecting unnecessary odor-emitting cartridges 1 and a holding space A2 for holding multiple replacement odor-emitting cartridges 1. By rotating the replacement module A like a revolver, unnecessary odor-emitting cartridges 1 can be replaced automatically or manually.

[0109] 12 is a schematic diagram showing a replacement module A of the odor generating cartridge 1 attached at a high place. The replacement module A attached at a high place can be lowered from the high place and rotated as needed by using a lifting module B equipped with a wire, string, or the like, as shown in FIG.

[0110] As a specific example of a method for replacing an odor-emitting cartridge 1, as shown in FIG. 13 , first prepare an odor-presenting unit 503 containing an unnecessary odor-emitting cartridge 1, a replacement module A, and a replacement arm A3 (see FIG. 13 a). During replacement, the replacement module A may be moved toward the odor-emitting cartridge 1, or the odor-emitting cartridge 1 may be moved toward the replacement module A. Next, the odor-presenting unit 503 containing the unnecessary odor-emitting cartridge 1 (shown in gray in FIG. 13 ) is positioned so that it is exactly in the collection space A1, and the replacement arm A3 is then automatically or manually moved (see FIG. 13 b). This moves only the unnecessary odor-emitting cartridge 1 to the collection space A1 (see FIG. 13 c). Then, the replacement module A is rotated so that the holding space A2 containing the replacement odor-generating cartridge 1 (shown in white in FIG. 13 ) containing the next desired fragrance is positioned in the odor-presenting unit 503 (see FIG. 13 d). Next, the replacement arm A3 is moved automatically or manually to load a replacement odor-generating cartridge 1 into the odor-presenting unit 503 (see e in Figure 13). Finally, the odor-presenting unit 503, replacement module A, and replacement arm A3 are returned to their original positions (see f in Figure 13). Using this replacement method, the odor-generating cartridge 1 in the odor-presenting unit 503 can be easily replaced. Note that in Figure 13, some of the holding space A2 is omitted from the illustration.

[0111] (12) Application Examples of the Odor Presentation Control System 500

[0112] The odor presentation control system 500 can be applied in a wide range of fields as described below.

[0113] Specifically, the device may be used in, for example, olfactory tests, olfactory training (including olfactory stimulation therapy), etc. The term "olfactory training" as used herein is broadly interpreted and includes practice for odor judgement tests, sommelier tests, aromatherapy certification, etc. In sommelier tests, for example, a wineglass-shaped odor presentation unit 503 incorporating an odor generating cartridge 1 may be used. The device may also be used for odor simulation when developing medicines, quasi-drugs, cosmetics, food and beverages, etc. Furthermore, the device may be installed in relaxation products such as head-mounted displays, neck pillows, massage chairs, eye pillows, eye massagers, head massagers, hand massagers, and foot massagers, as well as in vehicles such as automobiles, buses, trains, ships, and aircraft.

[0114] Additionally, it may be used in products for attracting customers, such as vending machines, signs, digital signage, robots, etc. It may also contribute to the presentation of scents corresponding to exhibits or plants and animals in art galleries, museums, libraries, zoos, botanical gardens, etc., and may be used as part of the production in concert halls, opera houses, live music venues, stages, movie theaters, amusement facilities, etc.

[0115] Other application examples overlap with the embodiments described below, but the present invention can also be applied to calming mood, elevating mood, helping people fall asleep, sleeping, and waking up comfortably, generating scents that pests and insects dislike, and generating scents in elevators, stores, offices, etc., depending on conditions such as time, location, and population density. Specific targets may be classified into ordinary people, athletes, pregnant women, hospitalized patients, babies, pet animals, etc., and scents appropriate for each target may be generated. In this case, the specific target may be one or more, and the scent presentation control system 500 may adjust the scent on a facility-by-facility basis in a gym where athletes gather, an obstetrics and gynecology clinic where pregnant women gather, a hospitalization facility where hospitalized patients gather, a veterinary clinic where pet animals gather, etc.

[0116] 2. Application Example 1 of the Odor Presentation Control System 500: Approach to Sleeping Situations

[0117] (1) Overview of approaches to sleep status

[0118] 14 is a block diagram showing an outline of an application of the odor presentation control system 500 to a sleep state. In this application example, the objective is to grasp the sleep state of a human or pet animal and then present an odor so that the subject is in a more comfortable state when falling asleep, sleeping, or waking up. The input unit 507 in FIG. 14 may be equipped with a Bluetooth module.

[0119] In this application example, first, information regarding the sleeping state of the specific subject is acquired by the information acquisition unit 501. As shown in Fig. 14 , examples of the information acquisition unit 501 in this application example include an environmental sensor that measures temperature, humidity, air pressure, etc., a vital sensor that measures pulse rate, etc., a camera that observes the position of a human or pet animal's face, how the animal turns over in its sleep, and recognition of a specific subject (e.g., a registered individual, family member, pet animal, etc.), and a brightness sensor that measures the amount of indoor lighting, etc. Furthermore, a wristband-type, stationary-type, mat-type, medical device, pet device, etc. may be used to check the sleeping state.

[0120] Next, in this application example, the control unit 502 classifies the sleep state of the specific subject into one of a sleep state, a sleep state, and a pre-wake state based on information regarding the sleep state of the specific subject, and the control unit 502 determines the odor presentation conditions according to the classified state.

[0121] Specifically, for example, when a subject is classified as in a sleep state, a vital sensor measures the pulse rate so that the subject can transition to sleep in a relaxed state, and when it is determined that the subject is relaxed, an additional scent is presented. In this case, the scent presenting unit 503 can be attached to the ceiling, for example, and an airflow containing scent-containing air can be directed from the ceiling to a specific target to avoid disturbing the subject's sleep. Alternatively, the scent presenting unit 503 may be in the form of a desk lamp, and the scent presenting unit 503 may be attached to the desk lamp.

[0122] Furthermore, if the subject is classified as being in a sleep state, a sleep meter can be used to determine whether the specific subject is in REM sleep, and an odor can be presented to induce deeper REM sleep, for example. Simultaneously with the presentation of the odor, the control device 1003 can adjust, for example, the temperature or air volume of an air conditioner. This allows for a stable sleep state. Furthermore, if the subject is classified as being in a pre-wake state, a vital sensor and a sleep meter can be used to present an odor that can wake the specific subject, allowing the subject to wake up refreshed.

[0123] In this application example, the AI ​​1001 may analyze the sleep state of the specific subject based on the information accumulated in the storage unit 504. In this case, an explanation of the analysis results by the AI ​​1001 may be output from a speaker or monitor, and in addition, the weather, transportation, schedule, etc. for the day may be output, and the start of the day may be notified. Furthermore, a clever message may be notified according to the state (e.g., physical condition, mood, etc.) of the specific subject. In addition, the control unit 502 may set music to be played from the microphone 1004 when the specific subject wakes up.

[0124] A preferred embodiment of this application example will be described below.

[0125] (2) App integration and linkage with other devices

[0126] In this application example, it is desirable that the software cooperates with an existing or new sleep-related application. In the case of new software, the software itself may function as the control unit 502. It is also desirable that the software be linked with a sleep monitor or other devices so that the sleep state can be observed using each device. Examples of "other devices" here include air conditioners, speakers, monitors, indoor lighting fixtures, etc.

[0127] (3) Location detection and pulse detection

[0128] It is desirable to sense the position of the face, the position of the feet, the direction of the body, etc. of a specific target and present an odor that matches that state. Even if the specific target is a family member or multiple pets, each can be sensed with a camera and each odor presenting unit 503 can present an odor that matches the individual state. It is also desirable to use a vital sensor to estimate the state of the specific target, such as whether the target is comfortable or uncomfortable, drowsy or awake.

[0129] (4) Utilizing AI1001

[0130] For example, when explaining the results of sleep analysis or when notifying the user upon awakening, the AI ​​1001 can use voices of idols, voice actors, actors, actresses, synthesized voices, etc. Note that these voices may be output to the translation device 1002 via the AI ​​1001 and translated into multiple languages ​​other than Japanese before being output.

[0131] Alternatively, a specific subject may be allowed to select a fragrance and try it for a certain period of time (e.g., one week). Furthermore, if there are multiple odor presentation units 503, different fragrances may be tested alternately on different days. In addition, information on sleep conditions due to changes in temperature, humidity, air pressure, etc. may be stored in the memory unit 504, and optimal fragrances for the sleep-onset state, sleep state, and pre-awakening state may be listed based on the information stored in the memory unit 504.

[0132] (5) Example of operation flow during sleep

[0133] FIG. 15 is a block diagram showing an example of a more detailed configuration of the odor presentation control system 500 when applied to a sleep state, and FIG. 16 is a flowchart showing an example of the operation of the odor presentation control system 500 when classified as a sleep state. First, the environmental sensors in the information acquisition unit 501 measure the air temperature, air pressure, and atmospheric pressure (S201). Because these measurements are likely to affect the sleep status of a specific subject and the fragrance presentation conditions, they are preferably measured each time the flow starts. Next, the odor presentation unit 503 presents, for example, a reference odor (S202). Next, the external control unit 5022 compares the data of the specific subject stored in the storage device with the odor presented by the odor presentation unit 503 to determine whether the odor is liked or disliked by the specific subject (S203). If the odor is disliked by the specific subject, a different odor is prepared and presented again by the odor presentation unit 503. The reference odor may be determined based on the results of machine learning using AI. For example, citrus scents, black tea scents, lavender scents, cedarwood scents, etc., which are known to be associated with the state before falling asleep, may be used. Note that these scents may be used in "(6) Example of operation flow in a sleep state" described later.

[0134] Next, if an odor that the specific subject likes or dislikes is presented, the pulse is measured using the vital sensor of the information acquisition unit 501 (S204). Next, the position of the specific subject's face is measured using a camera (S205). If the external control unit 5022 determines that the specific subject is in an excited state based on the vital signs as a result of these measurements (S206), the process returns to S204. On the other hand, if the external control unit 5022 determines that the specific subject is in a sedated state based on the vital signs (S206), the process starts presenting an odor from the odor presentation unit 503 (S208). Then, the vital sensor is used again to check the pulse, thereby confirming whether the specific subject is in an active state based on the vital signs (S209). The confirmation in S209 may be performed repeatedly, for example, at regular intervals (e.g., every 5 minutes, 10 minutes, etc.).

[0135] If the subject is determined to be in an active state, the process returns to S208. On the other hand, if the subject is determined to be in a sleep state, the scent presentation unit 503 stops presenting the scent (S210). Once the subject falls asleep (S211), information such as the subject's bedtime and the scent used to fall asleep is stored in a recording device (S212). Note that, during this flowchart, the subject can also be set to a self-sleep mode (S207). While this flowchart is being executed, the controller 1003 (e.g., an air conditioner), audio / music from the microphone 1004, and various lighting fixtures using brightness sensors may be linked at appropriate times.

[0136] (6) Example of operation flow in sleep state

[0137] FIG. 17 is a block diagram showing an example of a more detailed configuration when the odor presentation control system 500 is applied to a sleep state, and FIG. 18 is a flowchart showing an example of the operation of the odor presentation control system 500 when classified as a sleep state. First, in this operation flow, the ambient temperature, atmospheric pressure, and air pressure are measured using the environmental sensors of the information acquisition unit 501 (S301). As described above, these are preferably measured each time the flow starts. Next, using, for example, a sleep meter, the external control unit 5022 determines whether the sleep state is light or deep (specifically, whether it is REM sleep or non-REM sleep, and the depth of non-REM sleep, etc.) (S302).

[0138] If the external control unit 5022 determines in S302 that the subject is in deep sleep, the subject continues to sleep (S307). After S307, the sleep state is again confirmed using a sleep monitor or the like after a predetermined time has elapsed (e.g., 1 hour, 1.5 hours, etc.), and it is determined, for example, whether the subject is in a sleeping state or is approaching awakening (S308). If the external control unit 5022 determines in S308 that the subject is in a sleeping state, the process returns to S301 again. On the other hand, if the external control unit 5022 determines in S308 that the subject is approaching awakening, information such as the awakening time of the specific subject and the scent used in the sleeping state is stored in a recording device (S309).

[0139] On the other hand, if the external control unit 5022 determines in S301 that the subject is in light sleep, the camera measures the position of the face of a specific subject (S303). Next, under the control of the internal control unit 5021, the scent presentation unit 503 starts presenting a scent toward the sensed face position (S304). Next, the sleep state is confirmed again using a sleep meter or the like, and it is determined whether the sleep state is light or deep (S305). If the external control unit 5022 determines in S305 that the subject is in light sleep, the process returns to S301 again.

[0140] On the other hand, if the external control unit 5022 determines in S305 that the subject is in deep sleep, the internal control unit 5021 instructs the odor presentation unit 503 to stop presenting the odor (S306). Then, the process proceeds to S307. The operations from S307 onward are as described above.

[0141] (7) Example of operation flow before waking up

[0142] FIG. 19 is a flowchart showing an example of the operation of the odor presentation control system 500 when the state is classified as a pre-wakeup state. A block diagram showing a more detailed example of the configuration of the odor presentation control system 500 when applied to a pre-wakeup state is similar to FIG. 15 . First, the external control unit 5022 checks whether it is time to wake up based on a built-in clock or the like (S401). If it is determined that it is before the wakeup time, the sleep continues (S402). After S402, the wakeup time may be confirmed again after a predetermined time has elapsed (e.g., 30 minutes, 1 hour, etc.) using a sleep monitor or the like (S401). Next, if it is determined that it is time to wake up, this operation flow also uses the environmental sensors of the information acquisition unit 501 to measure the air temperature, temperature, and air pressure (S403). As described above, these are preferably measured at the start of each flow. Next, the external control unit 5022 determines whether the state is asleep or awake using, for example, a sleep monitor or the like (S404). Next, whether the subject is asleep or awake, the vital signs are checked using a vital sensor (S405).

[0143] If the user is determined to be awake in S405, the camera measures the face position of the specific target (S406), and the scent presentation unit 503 starts presenting a scent at a normal strength (concentration) based on instructions from the internal control unit 5021 (S407). Next, the vital signs are checked again using the vital sensor (S405). If the user is determined to be awake, scent presentation is stopped (S409). Subsequently, output is provided to the monitor, and the AI ​​analysis results of the sleep status, today's weather, current transportation information, etc. may be displayed to the specific user upon waking (S410). Furthermore, audio output may also be provided, and for example, an explanation of the AI ​​analysis results of the sleep status, witty remarks, etc. may be spoken to the specific user using a voice of an idol, voice actor, actress, actor, or synthetic voice (S411). Information such as the specific target's exact wake-up time and the scents used before waking that were effective are stored in a recording device (S412).

[0144] Next, if it is determined in S405 that the subject is asleep, the camera measures the position of the face of the specific subject (S408), and the scent presentation unit 503 starts presenting the scent (S409). In this case, it is preferable that the scent presented to the specific subject be a strong scent, a scent presented with a high ejection frequency, a stimulating scent, a scent that is effective in waking the subject from drowsiness, or the like.

[0145] Thereafter, the vital signs are checked again using the vital sensor (S405). If the specific subject is still asleep, the process returns to S408. That is, if the control unit 502 (in this specific example, the internal control unit 5021, but it may also be the external control unit 5022) classifies the specific subject as being in a pre-wake state, the control unit 502 presents an odor until the specific subject wakes up (S409). Then, each time an odor is presented, the vital signs are checked using the vital sensor (S405), and it is determined each time whether the specific subject is still asleep or awake. If it is determined in S405 that the specific subject is awake, the process proceeds to S409. The operations from S409 onwards are as described above.

[0146] While this flowchart is being executed, linkage with a control device 1003 such as an air conditioner, audio / music from a microphone 1004, and various lighting fixtures using brightness sensors may be performed at appropriate times.

[0147] (8) Other

[0148] In this application example, the main information used for making a decision is information from a vital sensor when falling asleep, information from a sleep meter when sleeping, and information from the vital sensor and sleep meter when waking up, but this technology is not particularly limited to these. Note that the vital sensor and sleep meter may be conventionally known, and may be, for example, wearable.

[0149] Furthermore, as shown in Figure 20, the placement of the odor presentation unit 503 in the room can be freely determined, and it may also be linked to applications such as lighting fixtures and smart home appliances in the room.

[0150] 3. Application Example 2 of the Odor Presentation Control System 500: Approach to the Target State

[0151] In this application example, the objective is to determine the state of a target (preferably a human) and then present an odor that matches the scene. To this end, in this application example, the information acquisition unit 501 determines the state of one or more targets, and the control unit 502 determines the odor presentation conditions based on the state.

[0152] The "human state" referred to here may include, for example, activity status (e.g., whether at work, doing housework, sleeping, commuting to work or school, returning home, receiving care, or providing care), physical condition, medical condition, mood (e.g., relaxed, concentrated, emotions such as joy, anger, sadness, and happiness), age, race, sex, muscle mass, fat mass, weight, height, and, in the case of women, whether pregnant or menstruating, but is not particularly limited in the present technology.

[0153] Below are some specific examples of presenting scents that match the scene based on each person's state.

[0154] [Specific Example 1] In this specific example, a person is presented with an aroma that awakens them when they do housework in the morning or afternoon, and a calming aroma when they return home in the evening or when they do housework at night. After trying out several different aromas, the system may also consider information acquired from environmental sensors such as temperature, room temperature, and air pressure, as well as vital sensors, and process the information using AI to select the optimal aroma.

[0155] [Specific Example 2] In this specific example, odors are presented to people, particularly athletes, during training, which is a condition in which the physical load is higher than that of the average person. Specifically, for example, because training requires high concentration and tension, it is possible to verbalize odors using AI and create individually optimized odors. Note that recent research has revealed that odors affect the performance of athletes, and the odor presentation control system 500 according to the present technology can also be used as a system for such athletes.

[0156] Furthermore, the control unit 502 or the user may evaluate whether a good performance was achieved for each scent, and the optimal scent for entering the concentration zone may be presented based on AI machine learning. Alternatively, the user may instruct the control unit 502 via the input unit 507 to create a desired environment. Furthermore, training may be performed by recreating scents similar to the actual environment based on information acquired by the information acquisition unit 501.

[0157] [Specific Example 3] In this specific example, for people, particularly pregnant women, an optimal scent is discovered to accommodate changes in preferences that the pregnant woman herself does not understand, and scents are presented to alleviate conditions such as morning sickness, abdominal pain, nausea, etc. Specifically, for example, it is known that olfactory changes occur during pregnancy, and even scents that normally do not bother the pregnant woman or even a slight ammonia scent (an unpleasant scent) can cause discomfort and make her feel ill. In this case, the information acquisition unit 501 detects the ammonia scent, and a scent to alleviate or prevent morning sickness is quickly presented.

[0158] It is also known that there are aromas that pregnant women should avoid as they have the effect of promoting menstruation (menstrual cycle) or stimulating hormone secretion, so if the information acquisition unit 501 senses an aroma that should be avoided, the control unit 502 can automatically stop the emission of the aroma, and then use the air blowing mechanism 506 to ventilate the room.

[0159] [Example 4] In this example, a calming scent is presented to one or more patients, particularly humans, or a soothing scent is presented when the patient is about to become active. Specifically, for example, the scent is presented as a form of self-care for the patient's family or the patient themselves, so that the scent can alleviate anxiety and unpleasant symptoms and soothe the mind and body. Furthermore, when an olfactory sensor detects a scent that is harmful to the patient, an air curtain is generated by blowing odorless air, protecting the patient from the harmful scent.

[0160] [Specific Example 5] In this specific example, a vital sensor is used to present an odor intended to stabilize the physical condition of one or more care recipients or caregivers. Specifically, for example, an odor intended to enhance concentration is presented to alleviate symptoms such as dementia. Alternatively, an odor may be presented to induce a cheerful or nostalgic mood. On the other hand, if a care recipient has a sensitive smell, an air curtain may be generated to avoid the odor from reaching only that person, or the odor-containing air may be directionalized to deliver the odor to other people while avoiding that person. Furthermore, eliminating odors specific to nursing care facilities or presenting odors that relieve stress can contribute to relieving stress for caregivers. In this way, the odor presentation control system 500 according to the present technology may be used to adjust the odor on a facility-by-facility basis.

[0161] [Specific Example 6] In this specific example, odorless air is used to prevent odors from reaching people, particularly sleeping babies, and is blocked by an air curtain or the like. Furthermore, when a baby sleeps with its parent, the control unit 502 may simultaneously control the parent to receive a directional airflow containing odor-containing air, while the baby receives only odorless air. Specifically, for example, strong odors such as fabric softener, perfume, and aroma are known to cause babies to cry at night, and therefore these odors should be avoided or prevented from reaching the baby. On the other hand, some odors, such as lavender, are known to be effective in relieving stress in babies, so lavender or other odors may be presented to the baby for both the purpose of preventing night crying and stress relief.

[0162] 4. Application Example 3 of the Odor Presentation Control System 500: Approaching a Specific Target

[0163] The purpose of this application example is to present a scent that is tailored to a specific target (preferably a human or an animal). Conventionally, it has been difficult to present a scent that is tailored to a specific target due to the problem of scent diffusion, but by carefully controlling the switching of scents and the timing of scent presentation, it is possible to present a scent that is tailored to a specific target.

[0164] 21 is a block diagram showing an outline of the odor presentation control system 500 when approaching a specific target. Specifically, for example, it is possible to control the presentation of an odor based on the target that appears. Examples of the target that appears include an unspecified number of people or animals, customers, children, babies, elderly people, people receiving care, caregivers, pet animals, etc., or a combination of one or more of these, but this technology is not particularly limited thereto. By presenting an odor to the target that appears, the following effects can be expected, for example.

[0165] [Specific Example 1] For example, it is possible to encourage a specific target's behavior. More specifically, for example, it is possible to encourage a child to move in the direction of a strong odor, to guide a pet animal to a toilet by emitting a pleasant odor near the toilet, or to move a person or animal from an undesired place by presenting an odor that the person or animal dislikes in order to prevent heatstroke or the like.

[0166] [Specific Example 2] For example, it is possible to change the state of a specific object. More specifically, for example, it is possible to relax the object by presenting a calming or favorite smell, or to concentrate by presenting a refreshing smell or a stimulating smell containing capsaicin.

[0167] [Example 3] For example, it is possible to smoothly respond when a specific target disappears. More specifically, for example, it is possible to present a scent with a deodorizing effect or to strengthen deodorization.

[0168] [Specific Example 4] For example, it is possible to avoid presenting an odor that a specific target dislikes. Specifically, for example, depending on the type or individual pet animal, there may be odors that the pet animal dislikes or should avoid. In such cases, it is possible to switch to a safe odor and present it, control the odor so that it does not reach the pet animal, or stop presenting the odor. In this case, the control unit 502 may be equipped with a pet mode optimized for pet animals rather than humans, and transitioning to the pet mode can ensure the safety of the pet animal. In addition, components other than odors may include, for example, components with pharmacological effects, components that insects dislike, and components that pests such as mosquitoes, cockroaches, and flies like, and these can also be utilized. Specifically, for example, it is possible to generate a component that pests like, attracting and exterminating the pests.

[0169] [Effects of the Present Application Example] Compared to conventional technologies, the present application example has the advantage that the scent does not reach non-target humans or animals, thereby avoiding unnecessary prompting of non-target human or animal behavior and causing no inconvenience. Furthermore, compared to prompting behavior using audio (including vocalizations) or images, the scent presentation conditions are controlled to pinpoint the scent and prompt the target to spontaneously behave based on the presented scent, thereby reducing stress on specific targets and non-target humans or animals. Furthermore, the present application example is expected to enable efficient behavioral learning (e.g., toilet training for infants or pet animals), and presenting a scent directional to a specific target has the advantage of eliminating cost and energy waste on fragrances and fragrance diffusion. The scent presentation conditions also use the sensing results from the information acquisition unit 501, allowing for more effective scent presentation.

[0170] 5. Application Example 4 of the Odor Presentation Control System 500: Approach to the Surrounding Environment

[0171] The purpose of this application example is to present an odor that matches the situation of the surrounding environment. Conventionally, it has been difficult to present an appropriate odor in response to changes in the surrounding environment, but by using the odor presentation control system 500, it is possible to present an appropriate odor.

[0172] Examples of the surrounding environment include indoor or outdoor brightness, time of day (e.g., sunrise, sunset, morning, afternoon, evening, working hours, bedtime, etc.), temperature, humidity, weather, etc., but the present technology is not particularly limited thereto.

[0173] 22 is a block diagram showing an outline of the odor presentation control system 500 when approaching a surrounding environment. Specific examples of presenting odors according to the state of each surrounding environment will be given below.

[0174] [Specific Example 1] Specific Example 1 relates to the presentation of an odor in response to changes in brightness. Specifically, for example, an odor may be presented or stopped depending on the brightness of the room. More specifically, for example, when the room becomes brighter due to the morning sun, an odor that helps wake you up may be presented, when the room becomes darker, an odor that helps you feel calm may be presented, and when the room becomes darker, the presentation of the odor may be stopped.

[0175] [Specific Example 2] Specific Example 2 relates to the presentation of odors in response to changes in temperature and humidity. Specifically, for example, odors are presented in response to the air temperature and / or humidity of a room. More specifically, for example, a cooling odor is presented when the temperature is high, a warming odor is presented when the temperature is low, and presentation of the odor is stopped when the temperature reaches an appropriate level.

[0176] [Specific Example 3] Specific Example 3 relates to the presentation of an odor according to time. Specifically, for example, an odor is presented according to time, such as at sunrise, sunset, or another designated time. More specifically, for example, an odor that helps wake up is presented at sunrise, and an odor that calms the mood is presented at sunset.

[0177] [Specific Example 4] Specific Example 4 relates to the presentation of scents according to work hours. Specifically, for example, when work or class starts, a scent that helps concentration is presented, when break time comes, a scent that helps relaxation is presented, and when work hours end, the presentation of scents is stopped. Furthermore, the presentation of scents may be stopped when the workplace, the floor where the workplace is located, the building where the workplace is located, etc. are locked.

[0178] 6. Application Example 5 of the Odor Presentation Control System 500: Approach to Air Conditioning

[0179] This application example aims to manage air conditioning using the odor presentation control system 500. Conventionally, hot or cold situations have been addressed solely by adjusting the air volume, air direction, and temperature of the air conditioning system 2001, which has resulted in problems such as time-consuming adjustment to the appropriate temperature and increased power consumption. In contrast, by using the odor presentation control system 500, it is possible to prevent the temperature setting of the air conditioning system 2001 from being adjusted up or down, thereby reducing power consumption and reducing the impact of air conditioning on humans and animals, while providing early comfort.

[0180] In addition, when managing air conditioning, if the air conditioning system 2001 is a smart home appliance, it may be linked to the odor presentation control system 500 via an application. The odor presentation unit 503 may be built into the air conditioning system 2001 or may be externally attached. Furthermore, the placement and number of the odor presentation units 503 may be appropriately determined by the user, taking into account the shape, placement, and number of furniture in the room, the area of ​​the room, etc.

[0181] Below, we will focus on a familiar air conditioner among the air conditioning systems 2001, and provide a specific example of air conditioner management using the scent presentation unit 503. Figure 23 is a block diagram showing an outline of the scent presentation control system 500 when approaching air conditioning. In Figure 23, the part described as "air conditioning system 2001" indicates, for example, an air conditioner.

[0182] (1) Specific example of air conditioning management 1

[0183] Since temperature control is the most important aspect of an air conditioner, the scent presentation unit 503 presents scents that stimulate the sense of warmth (capsaicin) or the sense of cold (menthol) to stimulate the trigeminal nervous system. Specifically, for example, if the user wants to set the ambient environment to an indoor sauna, capsaicin is presented. In this case, there is no need to lower the set temperature, which reduces power consumption.

[0184] (2) Specific example of air conditioning management 2

[0185] Human sensory organs interact with each other, a phenomenon generally referred to as cross-modality (interaction between senses). The following specific examples utilize this cross-modality. Specifically, when air conditioning and an odor that humans perceive as cold (e.g., Sea Island, cotton) are presented, humans are more likely to perceive cold compared to when air conditioning is used alone. Similarly, when heating and an odor that humans perceive as warm (e.g., pumpkin, cinnamon) are presented, humans are more likely to perceive warm compared to when heating is used alone. By utilizing this effect, excessive temperature fluctuations in air conditioners can be prevented, reducing power consumption. Furthermore, because cool air accumulates at the bottom of a room, it is preferable for the odor to be discharged from bottom to top. On the other hand, because warm air accumulates at the top of a room, it is preferable for the odor to be discharged from top to bottom.

[0186] (3) Additional control example 1 for air conditioning management

[0187] In addition, for air conditioning management, the information acquisition unit 501 is used to sense the state of the target, the state of the room, the temperature, humidity, the position of the target, the distance from the odor presentation unit 503 to the target, etc., and based on the sensing results, the control unit 502 determines the direction of odor emission, the type of odor, the duration of odor emission, and whether or not to emit additional odors, thereby presenting odors more efficiently. In this case, examples of the information acquisition unit 501 include a thermometer, a motion sensor, and depth sensing. Additionally, it is possible to control additional odor presentation conditions according to the surrounding environment desired by the user (e.g., an indoor sauna, a snow hut, a beauty salon, etc.). Examples include control of the air volume during emission, the type of odor (e.g., forest odor), etc. In addition, humidity may be controlled by linking with a humidifier connected via a wired or wireless connection.

[0188] (4) Additional control example 2 for air conditioning management

[0189] In addition, when the state or environment is such that it is desirable to use or increase the heating or cooling, an alert may be issued from the warning unit. More specifically, for example, in a high temperature and humidity state or a state where there is a risk of heatstroke, a predetermined odor may be presented. On the other hand, for example, in an environment where there is a risk of frostbite or a state where there is a risk of hypothermia, a predetermined odor may be presented. In addition to presenting the odor, a display on the screen of a monitor or mobile information terminal, or a voice notification from a smart speaker may be given. Furthermore, it is also possible to perform content linkage 2003 with games, videos, music, etc., read one-dimensional or two-dimensional codes to automatically control the odor presentation conditions, or detect the screen to provide a thermal sensation to the user.

[0190] (5) Air conditioning control flow example 1

[0191] Fig. 24 is a flowchart showing an example of the operation of air conditioning management using the odor presentation control system 500. In the flowchart shown in Fig. 24, first, the user turns on the air conditioning (air conditioner) (S601). Next, the temperature and humidity are measured using the environmental sensor constituting the information acquisition unit 501 (S602). Next, the user sets the environment 2002, and the control unit 502 determines the operation of the air conditioning (air conditioner) to approximate the set environment, and the determined operation is started (S603).

[0192] For example, when a user decides to operate the air conditioner or dehumidifier, the controller 502 first determines whether the air conditioner or dehumidifier is operating correctly (S604). Then, only if the controller 502 determines that the air conditioner or dehumidifier is operating correctly, the controller 502 presents a cooling odor (e.g., Sea Island or Cotton) to the user (specific target) (S606). After a predetermined time has elapsed, the controller 502 determines whether the desired environment setting has been reached (S606). If the controller 502 determines that the desired environment setting has been reached, the controller 502 turns off the air conditioner and / or stops presenting the odor (S611). The determination of whether the desired environment setting has been reached may be made, for example, by estimating whether the specific target is comfortable or uncomfortable based on information obtained from a temperature sensor or a vital sensor. On the other hand, if the controller 502 determines that the desired environment setting has not been reached, the controller 502 returns to S603. Although not shown in the flowchart of FIG. 24, the controller 502 may control the odor-containing air emitted from the odor display unit 503 so that the direction of discharge is from bottom to top, if necessary.

[0193] For example, when a user decides to activate the heater, the controller 502 first determines whether the heater is operating correctly (S607). Then, only if the heater is operating correctly, the odor presentation unit 503 presents a warming odor (e.g., pumpkin, cinnamon, etc.) to the user (specific target) (S608). After a predetermined time has elapsed, the controller 502 determines whether the desired environment setting has been achieved (S606). If the desired environment setting has been achieved, the controller 502 turns off the air conditioner and / or stops presenting the odor (S611). The determination of whether the desired environment setting has been achieved may be made, for example, by estimating whether the specific target is comfortable or uncomfortable based on information obtained from a temperature sensor or a vital sensor. On the other hand, if the desired environment setting has not been achieved, the controller 502 returns to S603. Although not shown in the flowchart of FIG. 24, the controller 502 may, if necessary, control the odor-containing air emitted from the odor presentation unit 503 so that the direction of discharge is from top to bottom.

[0194] Furthermore, for example, when a user decides to operate the air blower or air purifier, the odor presentation unit 503 first determines whether the air blower or air purifier is operating correctly (S609). Then, only if it is determined that the air blower or air purifier is operating correctly, does the odor presentation unit 503 present an arbitrarily set odor to the user (specific target) (S610). After a predetermined time has elapsed, it determines whether the desired setting environment has been reached (S606). If it is determined that the desired setting environment has been reached, the air conditioner is turned off and / or the presentation of the odor is stopped (S611). Note that the determination of whether the desired setting environment has been reached may be made by, for example, estimating whether the specific target is comfortable or uncomfortable based on information obtained from a temperature sensor or vital signs sensor. On the other hand, if it is determined that the desired setting environment has not been reached, the process returns to S603.

[0195] (6) Air conditioning control flow example 2

[0196] Fig. 25 is a flowchart showing an example of the operation when air conditioning management is performed using the odor presentation control system 500. In the flowchart shown in Fig. 25, first, the user measures the surrounding environment using the information acquisition unit 501 (S701). Here, the measurement is performed using, for example, environmental sensors that measure temperature, humidity, air pressure, etc., and human presence sensors that measure vital signs, position, etc. Next, based on the measurement results, the location of the target and the surrounding temperature conditions are identified (S702).

[0197] For example, if there is an area where the temperature is above a predetermined level (S703), cool air is blown from the air conditioner and a scent that gives a cooling sensation (e.g., Sea Island or Cotton) is presented from the scent presentation unit 503 to a specific target (S704). After a predetermined time has elapsed, optionally, information is output from the output unit 505, an alert is displayed on the screen of a monitor, a mobile information terminal, or the like, or an audio alert is issued from a smart speaker, etc. (S705). After the alert is stopped, the process returns to S702.

[0198] Also, for example, if there is an area where the temperature is below a predetermined temperature (S706), warm air is blown from the air conditioner and a warming smell (e.g., pumpkin, cinnamon, etc.) is presented from the smell presenting unit 503 to a specific target (S707). Then, after a predetermined time has elapsed, optionally, information is output from the output unit 505, an alert is displayed on the screen of a monitor, a mobile information terminal, etc., or an audio alert is issued from a smart speaker, etc. (S705). Then, after the alert is stopped, the process returns to S702 again.

[0199] Furthermore, for example, if there is an area within a predetermined temperature range (S709), the odor presentation unit 503 presents a standard odor to the specific target (S710). Then, the process returns to S702.

[0200] In S703, S706, and S709, the determination is made based on the results of sensing by the environmental sensor, but in addition to this, the preferred state of each subject may be sensed and the odor presentation conditions may be set for each specific subject.

[0201] Also, although not shown in the flowchart of Figure 25, if necessary, the above-mentioned "(3) Additional control example 1 in air conditioning management" and / or "(4) Additional control example 2 in air conditioning management" may be performed at any timing.

[0202] (7) Air conditioning control flow example 3

[0203] FIG. 26 is a flowchart showing an example of the operation of air conditioning management using the odor presentation control system 500. In the flowchart shown in FIG. 26, first, the user turns on the air conditioning (air conditioner) (S801). Next, the desired environmental conditions are set manually or automatically (S802). When setting the environment manually, the desired environmental conditions are input to the control unit 502 via the input unit 507. When setting the environment automatically, the control unit 502 sets the desired environmental conditions based on the results of sensing (e.g., image sensing) obtained from the information acquisition unit 501. Next, the air conditioning (air conditioner) and odor presentation operations that will bring the environment closer to the set environment are determined, and the determined operations are initiated (S803).

[0204] Next, it is determined whether to change the set environment manually or automatically (S804). If the determination is made manually, the determination result is input to the control unit 502 via the input unit 507. If the determination is made automatically, at the time of S804, sensing is performed by the information acquisition unit 501, and the state of a specific target is estimated from the sensing results (e.g., temperature, humidity, vital signs, etc.) obtained from the information acquisition unit 501, and the control unit 502 determines whether the set environment is close to the set environment. In this case, a predetermined standard (e.g., a threshold value) may be set for the sensing results, and the control unit 502 may make a determination based on this standard. Next, if it is determined that the set environment will not be changed, the presentation of the set odor continues (S805). On the other hand, if it is determined that the set environment will be changed, the process returns to S802 again.

[0205] Also, although not shown in the flowchart of FIG. 26, if necessary, the above-mentioned "(3) Example 1 of additional control in air conditioning management" and / or "(4) Example 2 of additional control in air conditioning management" may be performed at any timing.

[0206] (8) Arrangement

[0207] In this application example, the arrangement of some or all of the components constituting the odor presentation control system 500 is not particularly limited, and examples include an independently driven type, a built-in type, an attached type, and the like.

[0208] Examples of the independently driven type include a type that is attached to any location using a magnet or the like, a stand type, a hanging type, and a wearable type (e.g., a headset, VR goggles, VR device, etc.). Examples of the built-in type include a device that is built into a blower device such as an air conditioner, air purifier, blower, fan, or ventilation fan. In this case, the moving source (power source), blower mechanism, exhaust port, intake port, and control unit of the blower device may be shared as desired. Examples of the attached type include a device that is attached to the above-mentioned blower device in line with the exhaust port or intake port. In this case, attachment methods such as attaching with a hook or clamping to a filter are available, but are not particularly limited in the present technology.

[0209] FIG. 27 is a block diagram assuming, for example, a built-in type in which parts of the blower device, such as the movable source, blower mechanism, exhaust port, and deodorizing or odor eliminating system or intake port, are shared with the odor presentation control system 500. When the exhaust port is shared with the odor presentation control system 500, the odor is presented from the odor presentation unit 503 by turning the exhaust on, and the odor presentation from the odor presentation unit 503 is stopped by turning the exhaust off. Also, when the deodorizing or odor eliminating system or intake port is shared with the odor presentation control system 500, the remaining odor is absorbed by turning the exhaust on, and the absorption of the remaining odor is stopped by turning the exhaust off. In this case, a deodorizing filter or the like may also be used. Also, even if the blower mechanism itself has an exhaust and intake system, the system can be used as part of the odor presentation control system 500 by performing operations similar to those described above.

[0210] In another embodiment, the odor presentation unit 503 can be placed on the bottom of an air conditioning device (e.g., an air conditioner) behind the fins. This eliminates the need to significantly change the internal structure of the air conditioner, and allows it to be introduced as an aftermarket part. Furthermore, since the odor presentation unit 503 is hidden by the fins of the air conditioner, it does not affect the external appearance. Note that in this technology, the first and second embodiments of the odor-generating cartridge 1 described above may be used instead of the odor presentation unit 503, or any other odor-generating module may be used.

[0211] The specific benefits of placing the unit on the bottom surface behind the air conditioner's fins are listed below. The large contact surface allows for stable installation of the scent presentation unit 503, etc. While the fins are operating, the scent presentation unit 503, etc. is obscured by the fins, reducing the impact on the exterior appearance. By placing the unit near the center of the bottom surface, the scent presentation unit can be expanded by utilizing the air conditioning wind to the maximum extent possible. Multiple scent presentation units 503, etc. can be arranged side by side, ensuring that the impact of the air conditioning wind is equal for each fragrance, thereby maximizing the scent presentation range and intensity of each fragrance. Multiple scent presentation units 503, etc. can be arranged side by side, enabling a common structure for the power supply mechanism, blower mechanism 506, etc. of the scent presentation unit 503, etc. The unit is located far from the air intake of the air conditioner, preventing scent contamination inside the unit. The scent is deposited on the discharged air, eliminating any areas for the scent to adhere, eliminating residual scents, and eliminating mixing when switching between units.

[0212] As a specific operational flow, first, the scent presentation unit 503, etc., as an aftermarket part, is attached to the air conditioner. The attachment position is preferably the bottom part behind the fins of the air conditioner, but it can also be attached to any other position, such as the side or bottom of the air conditioner, or in front of the fins (on the opening / closing side). Next, the scent presentation unit 503, etc. is turned on. Here, one or more scents can be used. Furthermore, the scent presentation unit 503, etc. itself can be one or more. If there are multiple scent presentation units 503, etc., further control may be performed to present multiple scent presentation units 503, etc. simultaneously or by switching between them. Next, the air conditioner is turned on. Note that the scent presentation unit 503, etc. and the air conditioner may be turned on simultaneously, or the air conditioner may be turned on first.

[0213] This allows the scent to be distributed locally in the area where the air conditioner's wind hits. The direction of the scent can also be changed depending on the direction of the air conditioner's wind. Furthermore, the scent can be spread vertically down into the space (for example, to the floor of the room).

[0214] The above-mentioned specific examples have been mainly explained with reference to air conditioners, but the following application examples are also possible for the installation position of the scent presentation unit 503, etc., in addition to the bottom surface of a home air conditioner: For example, the flat area surrounding the fins of a ceiling-mounted commercial air conditioner, or the flat area other than the fins on the top surface of an air purifier or humidifier (if it is located behind the fins, it will have the same effect as an air conditioner).

[0215] (9) Linkage

[0216] In this application example, the form of interlocking of some or all of the components constituting the odor presentation control system 500 is not particularly limited. For example, as shown in the above-mentioned FIG. 20 , multiple odor presentation units 503 arranged in a room can be aggregated and registered in a single application, and each odor presentation unit 503 can be operated under desired odor presentation conditions. Furthermore, the odor presentation unit 503 may operate based on detection by various sensors constituting the information acquisition unit 501. For example, when a human sensor detects entry into the room or when the key lock is released, an odor is presented to a specific target. Furthermore, the system can also be interlocked with smart home appliance applications. For example, when an air conditioner, lighting, cooking appliances, refrigerator, etc. are turned on, an odor with a cooling or warming sensation can be presented depending on the room temperature.

[0217] The control unit 502 may further include a mechanism for switching between different scents, utilizing mechanisms for controlling the air conditioner's operating mode, room temperature detection, and set temperature. For example, it is conceivable that the user will be presented with scents such as lavender or grapefruit during cooling operation, and spice or curry during heating operation.

[0218] 7. Application Example 6 of the Odor Presentation Control System 500: Approach to Spatial Situations

[0219] (1) Overview of the approach to spatial situations

[0220] In this application example, spatial conditions are particularly addressed among the conditions of the surrounding environment. The "spatial conditions" referred to here include, but are not limited to, the temperature, humidity, area (size), ceiling height, human or animal density, and frequency of human or animal entry and exit (including the concept of getting on and off) in a space such as indoors, outdoors, a room, a limited space, a floor, or an entire building. Furthermore, the "limited space" referred to here refers to a space that is clearly separated from other places, such as inside an elevator, a car (including a taxi), a bus, a train, a ship, or an aircraft, but is also a broad concept that includes inside a concert hall, an opera house, a live music venue, a theater, a movie theater, an art gallery, a museum, a library, etc.

[0221] In this application example, a specific example will be given that focuses on a familiar elevator, among other limited spaces.

[0222] (2) Operation flow example 1

[0223] FIG. 28 is a flowchart showing an example of the operation when approaching a spatial situation using the odor presentation control system 500. The odor intensity from the odor presentation unit 503 in an elevator varies drastically depending on the frequency of people getting on and off. When people get on and off frequently, the odor is perceived as weak and ineffective, while when people get on and off infrequently, the odor is perceived as strong and can be painful. Therefore, in this specific example 1, the objective is to maintain a constant odor intensity in the elevator. Specifically, the explanation will be given using the flowchart shown in FIG. 28, assuming that at least the odor presentation unit 503 is installed in an elevator with a capacity of L, for example.

[0224] In this specific example 1, first, the control unit 502 instructs the elevator to present an odor at an appropriate odor concentration C for passengers, and then stops presenting the odor (S1001). In this case, information is acquired using the following two approaches: (i) The time T that the elevator doors are open is acquired by linking with the computer that controls the elevator (S1002). (ii) The number of people boarding the elevator, X, and the number of people exiting the elevator, Y, are calculated by processing the video captured by a camera inside the elevator (S1003).

[0225] Next, using the information on the capacity L, the odor concentration C, the time T per period D, the number of people X, and the number of people Y acquired or calculated by (i) or (ii) above, the control unit 502 calculates an appropriate operating time t for the odor presentation unit 503 (S1004). Then, the odor presentation unit 503 operates only for the calculated operating time t, and then stops presenting the odor. By implementing this specific example 1, the odor intensity inside the elevator can be maintained constant.

[0226] (3) Operation flow example 2

[0227] 29 is a flowchart showing an example of the operation when approaching a spatial situation using the odor presentation control system 500. In this example, the objective is to provide a valuable experience to customers by switching the presented odor depending on the destination floor of the passenger in the elevator, presenting an appropriate odor depending on the passenger's destination floor, and providing a valuable experience to customers. It is also possible to present an odor only to a specific individual, or to present an odor or not present an odor depending on the number of passengers in the elevator.

[0228] More specifically, the process will be described with reference to the flowchart shown in Figure 29. In this second specific example, it is assumed that a passenger enters the elevator and presses the destination floor button (S2001). In this case, information is acquired using the following two approaches: (i) The elevator's destination floor is detected (S2002). (ii) Image a obtained from a camera inside the elevator is processed to detect passenger B who pressed the destination floor button (S2003). Next, passenger B who pressed the destination floor button moves to a place where he or she can relax (S2004). Then, the image a is processed to detect the location of passenger B in the elevator (S2005).

[0229] Next, if there are no other passengers within a radius of X cm from passenger B (including the case where passenger B is the only passenger in the elevator) (S2006), the control unit 502 controls the odor presentation unit 503 to present an odor according to the destination floor toward the location of passenger B (S2007). For example, if there is a food court on the destination floor, the odor of food may be presented, or if there is a horror attraction on the destination floor, a fishy or damp odor may be presented.

[0230] On the other hand, if there are other passengers within a radius of X cm from passenger B (S2008), the control unit 502 determines not to present the scent (S2009). This prevents the scent from affecting anyone other than the specific target. By implementing this specific example 2, a scent optimized for a specific target can be presented according to the destination floor in the elevator, while a scent that does not affect anyone other than the specific target can be presented.

[0231] (4) Operation flow example 3

[0232] 30 is a flowchart showing an example of the operation when approaching a spatial situation using the odor presentation control system 500. In this specific example 3, the objective is to appropriately present odors according to the number of target people, in response to the problem that, in conventional technology, odors are not presented in synchronization with advertisements and the odor presentation conditions cannot be changed according to the number of people or range. Specifically, the following description will be given using the flowchart shown in FIG. 30.

[0233] In this specific example 3, first, a target is assumed to be getting on an elevator or standing in front of an elevator waiting for the elevator (S3001). Next, the information acquisition unit 501 detects that the target has gotten on the elevator or that the target has stood in front of the elevator (S3002). Next, the information acquisition unit 501 detects the number of targets who have gotten on the elevator or who are waiting for the elevator (S3003). Next, based on the information obtained from the information acquisition unit 501, the output unit 505 outputs an advertisement (e.g., an image, a video, etc.) on a digital signage or the like (S3004).

[0234] Next, in conjunction with the advertisement, the odor presentation unit 503 presents the odor at an emission amount (or emission range) according to the number of subjects (S3005). Next, the information acquisition unit 501 detects an increase or decrease in the number of subjects in the elevator or the number of subjects waiting for the elevator (S3006). Then, depending on the changed number of subjects, the odor presentation unit 503 again presents the odor at an emission amount (or emission range) according to the number of subjects (S3007).

[0235] In this specific example 3, when the advertisement is switched to the next advertisement or when a target gets off the elevator, the control unit 502 may be linked with the elevator ventilation system to increase ventilation or perform deodorization using the deodorizing mechanism. In this case, the information acquisition unit 501 may measure (preferably continuously) the distance from the target to the elevator door to estimate the timing when the target will get off the elevator, and perform the above-mentioned operations such as increasing ventilation or performing deodorization using the deodorizing mechanism in accordance with that timing. By implementing this specific example 3, it is possible to present an appropriate scent depending on the number of targets in the elevator.

[0236] (5) Operation flow example 4

[0237] 31 and 32 are flowcharts showing an example of the operation when approaching a spatial situation using the odor presentation control system 500. In this specific example 4, the objective is to reduce power consumption, reduce stress for the subject using the elevator, and promote the health of the subject using the elevator in response to problems such as increased power consumption due to elevator use, reduced stress for the subject using the elevator, and increased medium- to long-term health risks due to a decrease in the subject's walking frequency.

[0238] The basic concept of this fourth example is to use an acceleration sensor to detect repeated intermittent stops and starts within a certain period of time in a moving object such as an elevator, and then present a specific odor. Presenting a specific odor based on machine learning results, such as a scent that many subjects find relaxing or pleasant, can be expected to seamlessly provide mental and physical relaxation without direct action or stimulation, or even awareness. Furthermore, presenting an odor that many subjects find repulsive based on machine learning results can be expected to eliminate the situation of unconsciously using the elevator without a clear reason, implicitly encouraging elevator users to exercise, and contributing to their health. Furthermore, reducing intermittent stops and starts, which are energy-inefficient, can be expected to reduce the power consumption of the elevator. The detection mechanism using the acceleration sensor, etc., can be remotely controlled, and the detection range can be automatically adjusted depending on the usage situation, etc.

[0239] More specifically, the following description will be given using the flowcharts shown in Figures 31 and 32. The flowchart shown in Figure 31 aims to relax elevator users when the elevator makes frequent stops. First, in the flowchart shown in Figure 31, it is assumed that a target is in the elevator (S4001). Next, an elevator function linked to the control unit 502 detects whether the elevator makes frequent stops (S4002). Alternatively, instead of S4002, the information acquisition unit 501, which includes an acceleration sensor, may detect whether the elevator stops and ascends or descends within a short period of time (S4003). Here, not only whether the elevator is ascending or descending, but also the speed of the ascending or descending movement may be detected.

[0240] Next, the control unit 502, which determines that the subject is dissatisfied based on the results of detection in S4002 and S4003, presents an odor to the subject (S4004). That is, by presenting an odor that many subjects find relaxing or a pleasant odor in S4004, the subject's dissatisfaction is reduced (S4005). By implementing this Example 4, it is possible to seamlessly present an appropriate odor that provides physical and mental relaxation to subjects using the elevator.

[0241] 32, the objective is to encourage subjects to exercise without using an elevator in order to promote their health. In this specific example 4, a desirable odor may be presented to a specific subject who is not obese, while an odor that is repulsive to the subject may be presented to a specific subject who is suspected of being obese. When the specific subject suspected of being obese gets off the elevator, the elevator may be immediately deodorized.

[0242] 32, it is assumed that an object has entered the elevator (S5001). Next, the elevator function linked with the control unit 502 detects whether the elevator has stopped and whether the doors have opened or closed (S5002). Alternatively, instead of S5002, the information acquisition unit 501 including an acceleration sensor may detect whether the elevator has stopped (S5003), and then a weight sensor may detect whether the object has entered the elevator (S5004).

[0243] Next, the elevator function checks whether the difference between the stop floor and the number of new button presses is within, for example, three (S5005). Next, an odor that is repulsive to the subject is presented (S5006), causing the subject to unconsciously refrain from using the elevator at nearby floors (S5007). By implementing this fourth example, it is possible to eliminate the situation of unconsciously using the elevator without a clear reason, implicitly encouraging elevator users to exercise, and contributing to their health. It is also expected to reduce the energy consumption of the elevator by reducing the intermittent stopping and starting, which is an energy-inefficient situation.

[0244] (6) Operation flow example 5

[0245] 33 is a flowchart showing an example of the operation when approaching a spatial situation using the odor presentation control system 500. In a moving object carrying a person, warnings of danger and operation instructions are transmitted visually and aurally, but this information is difficult to convey when sensory organs are limited (e.g., a visually impaired person, a hearing impaired person, or when using earphones or a smartphone). Therefore, the present technology aims to enable a person with limited sensory organs to understand warnings and operation instructions.

[0246] Specifically, for example, when a mobile object warns a person of danger, the mobile object detects the danger and then presents an unpleasant odor from the odor presenting unit 503 attached to the mobile object, causing the person to detect the danger. Also, when a mobile object informs a person of various information, the mobile object detects various information and then presents the information to a visual information presenting device, and at the same time presents an odor that the person finds pleasant based on machine learning, past history, etc., causing the person to detect the odor and be prompted to check the visual information presenting device.

[0247] More specifically, this will be described using the flowchart shown in FIG. 33 . The flowchart in FIG. 33 aims to convey warnings to specific targets, such as those with visual or hearing impairments, because warnings are difficult to convey to these targets. First, in the flowchart shown in FIG. 33 , it is assumed that the elevator doors are open (S6001). Next, it is confirmed that the elevator doors have been open for a certain period of time longer than X (S6002). If the elevator doors have been open for a certain period of time longer than X, an alarm is sounded for the target (S6003). Next, a camera detects that the target has not responded to the alarm (S6004). Next, an odor undesirable to the target is presented based on machine learning, past history, etc. (S6005). By implementing this fifth example, it is possible to convey warnings to those with visual or hearing impairments.

[0248] (7) Operational flow example 6

[0249] 34 is a flowchart showing an example of the operation when approaching a spatial situation using the odor presentation control system 500. In this specific example 6, the purpose is to address the problem that people tend to become uncomfortable when they have to wait in a queue or other situations, by relaxing people during the waiting time and easing the discomfort.

[0250] Specifically, the odor presentation control system 500 according to this specific example 6 includes at least an information acquisition unit 501 that detects a person's waiting time, a control unit 502 that determines the type of odor, etc. based on the detected waiting time, and an odor presentation unit 503 that presents the odor.

[0251] More specifically, the description will be given using the flowchart shown in Figure 34. The flowchart shown in Figure 34 aims to alleviate the irritation felt when an elevator stops frequently, delaying arrival at the destination floor. First, in the flowchart shown in Figure 34, it is assumed that an elevator button is pressed (S7001). Next, it is confirmed that the number of pressed floor buttons on the elevator is greater than a certain number X (S7002). Next, if the number of pressed floor buttons on the elevator is greater than the certain number X, a relaxing scent is presented to the subject (S7003).

[0252] That is, in this Example 6, the arrival time to the desired floor is estimated from the number of floor buttons pressed on the elevator, and the subject is allowed to relax. If necessary, a different scent can be presented for each floor at which the elevator stops, preventing the subject from becoming bored and allowing the subject to estimate the floor at which the elevator has stopped. For example, the scent of cosmetics can be presented on a cosmetics floor, and the scent of men's perfume can be presented in a men's clothing department. By implementing this Example 6, it is possible to alleviate frustration in situations where waiting times exceed a certain level and cause frustration.

[0253] 8. Application Example 7 of the Odor Presentation Control System 500: Approaching a Moving Object

[0254] In this application example, a moving object carrying a specific target is approached. The term "moving object" as used herein refers to, for example, a vehicle, a ship, an aircraft, etc. Examples of vehicles include automobiles, motorcycles, stand-up vehicles with electric power units, and trains (including streetcars). Examples of automobiles include electric vehicles, fuel cell vehicles, hybrid vehicles, buses, small commuter vehicles, and electric carts. Examples of motorcycles include electric motorcycles, electric tricycles, and electric bicycles. Examples of ships include boats, hovercrafts, jet skis, submarines, submersible boats, and underwater scooters. Examples of aircraft include airplanes, airships or balloons, hot air balloons, helicopters, and drones. This broad concept also includes linear motor cars, bullet trains, elevators, escalators, ropeways, trolleys, gondolas, lifts, and cable cars.

[0255] Note that each of the specific examples shown below may be linked to a navigation system possessed by a moving object (for example, a car navigation system in the case of a car), or a smartphone, wearable device, tablet device, etc. owned by a specific subject.

[0256] (1) Examples of dramatic effects

[0257] In this example, the purpose is to use scents to target specific objects inside the vehicle. Specifically, for example, scents linked to the weather may be presented based on the current weather and weather forecasts obtained by the information acquisition unit 501, or scents may be presented based on the current location of a vehicle that repeatedly travels a specific route, such as an airplane, linear motor car, bullet train, train, or bus.

[0258] More specifically, for example, airplanes include both international and domestic flights, and on airplanes, scents specific to each country or region may be presented, while on linear motor cars, bullet trains, trains, etc., scents specific to each region or prefecture may be presented. Furthermore, when a linear motor car, bullet train, train, etc. approaches the sea or mountains, the scent of the sea or mountains may be presented. Furthermore, if a subject wants to sleep comfortably on an airplane, it is also possible to present a directional scent that is preferred by the subject.

[0259] Specific examples of the unique smells of each prefecture include presenting the smell of tea when approaching Shizuoka Prefecture or when the current location is within Shizuoka Prefecture, and presenting the smell of mandarin oranges when approaching Wakayama Prefecture or Ehime Prefecture or when the current location is within Wakayama Prefecture or Ehime Prefecture.

[0260] In this way, the odor presentation control system 500 can control odors by selecting the type of odor or changing the odor to present a different odor based on information about the current location of the vehicle carrying the specific target. Also, if the current location is close to the destination of the specific target, presenting an odor specific to the destination can be used as an alert just before the target arrives at the destination.

[0261] In this case, the amount of scent emitted may be controlled depending on the number of specific targets to which the scent is to be presented, or the amount and speed of scent emission may be controlled depending on the speed of the moving object, etc.

[0262] (2) Examples of entertainment or advertising purposes

[0263] In this specific example, the purpose is to provide entertainment or advertising using smells to a specific target riding in a vehicle. Specifically, for example, when a specific target is moving, smells can be presented in conjunction with content such as videos. In this case, it is possible to provide 4D smell presentation as an added value for green seats, first class, etc. Furthermore, for example, when a specific target is taking a virtual tour, smells can be presented according to the images, videos, etc. being viewed. Furthermore, for the purpose of advertising to a specific target, the map and smell presentation can be linked, and for example, for a store that has paid an advertising fee (e.g., a restaurant, a florist, etc.), a smell highly related to the store can be presented when the specific target approaches.

[0264] (3) Examples of warnings based on danger detection

[0265] In this specific example, the purpose is to warn a specific target by detecting danger. Specifically, for example, if a sleepy expression is detected by a facial recognition sensor for a specific target driving a mobile vehicle, an odor suitable for waking the target from drowsiness may be presented, or the driving time may be automatically measured and, when a predetermined time determined to be long has elapsed, a refreshing odor or an odor suitable for waking the target from drowsiness may be automatically presented. Another example is presenting an odor to complement the specific target's senses in accordance with a situation outside the specific target's field of vision. More specifically, for example, if a mobile vehicle approaches behind the specific target or if a human or animal is detected outside an area illuminated by the mobile vehicle's lights at night, an odor may be presented to warn the specific target of impending danger.

[0266] Furthermore, if a human or animal attempts to harm a mobile object owned by a specific subject (e.g., a car break-in, a stray cat's mischief, etc.), a scent that repels the human or animal can be presented to warn or repel the attacker. In this case, various sensors constituting the information acquisition unit 501 can be installed inside and outside the mobile object. In addition, if the specific subject is a novice driver, the scent can be presented to suppress the sense of speed, prompting the driver to brake earlier. In this case, if the speed of the mobile object is significantly faster than the legal speed limit, the scent of burnt tires can be presented to the specific subject. This utilizes the cross-modal phenomenon in which the sense of speed perceived by humans changes depending on the type of scent. Note that the suppression of the sense of speed can be controlled depending on the type of road, such as an ordinary road or a highway.

[0267] In addition, when a danger approaches a vehicle driven by a specific subject, a scent that sharpens the senses can be presented to the subject, allowing the subject to avoid the dangerous situation. For example, V2X (i.e., between vehicles, or between a vehicle and a pedestrian) can be detected using an automobile's radar system, and a specific scent that sharpens the senses can be strongly presented to the driver.

[0268] (4) Specific examples aimed at providing a comfortable ride

[0269] In this example, the objective is to provide a comfortable ride for a specific target riding on a moving object. Note that the "specific target" in this example is a broad concept that includes not only a target driving the moving object, but also a target simply riding on the moving object.

[0270] Specifically, for example, a specific subject who is accustomed to driving a mobile vehicle may be presented with an uplifting scent while driving. In this case, for example, by using scents to create a sense of realism when turning a curve on a mountain road, it is possible to induce excitement in the specific subject and to expect effects such as stress relief. In this case, it is also possible to present the scent to the specific subject by deliberately shifting the scent emission direction to the left or right depending on the curve. Furthermore, dynamic scent presentation conditions can be controlled by changing the type of scent according to the driving conditions of the mobile vehicle (for example, acceleration (brake and accelerator in the forward and backward directions, steering wheel and curves in the left and right directions), etc.), or by changing the scent intensity, scent reach, scent emission direction, etc. by controlling the air volume of the air source.

[0271] More specifically, for example, an accelerometer and / or a gyroscope is used as the information acquisition unit 501 to detect the acceleration and curve of the moving object. It is preferable to use both an accelerometer and a gyroscope, and more preferably an external 6-axis IMU (3-axis accelerometer + 3-axis gyroscope). Using these, for example, an increase in acceleration or an increase in the G-value of the moving object to the side can be detected, and the scent can be changed and presented. In this case, in the case of a left curve, the scent can be presented by shifting the scent emission direction from the left side to the right side of the center of the target's face. The transition speed can be determined according to the curvature of the curve. Furthermore, for a sharp curve, it is possible to increase or decrease the transition speed of the scent emission direction. The scent emission direction can be changed using the air blowing mechanism 506. Furthermore, it is also possible to incorporate intensity and express the feeling of approaching by controlling the intensity.

[0272] Furthermore, by linking information from the IMU with information from the navigation system, it is possible to enhance the accuracy of the above-mentioned scent changes and present additional scents. More specifically, for example, when driving on a monotonous road or at a monotonous speed, a unique scent can be presented to prevent a specific target from getting bored. In addition, the specific target does not necessarily have to be the driver. For example, it is also possible to use the VR IMU to detect the G value of a moving object while driving and present the scent.

[0273] 35 is a block diagram showing an example of an outline of the application of the odor presentation control system 500 to a comfortable ride. As shown in FIG. 35, the information acquisition unit 501 in this specific example uses a 6-axis IMU that detects acceleration and curves, an engine RPM sensor that detects acceleration or deceleration, a steering wheel rotation angle sensor that detects curves, and a speed sensor that detects speed to check the running state of the vehicle, an external camera that detects the position and expression of the face, a smart watch that detects heart rate, blood pressure, breathing, etc., and sensors attached to the steering wheel, seat, etc. to check the state of the occupant (including identification of the occupant), and an environmental sensor that detects temperature, humidity, air pressure, brightness, volume, etc. inside the vehicle, and content such as music and video to grasp the state inside the vehicle, and an environmental sensor that detects temperature, humidity, air pressure, brightness, volume, etc. outside the vehicle, a GPS that detects position information and map information, LiDAR, M2M, sensors, etc. that detect approach information of other vehicles, and a camera that detects the state outside the vehicle to grasp the situation outside the vehicle.

[0274] The information acquired by the information acquisition unit 501, which is made up of these sensors, is transmitted via wire or wireless to the external control unit 5022. The external control unit 5022 determines the odor presentation conditions (for example, the type of odor in this case) by combining the driving state, the state of the occupants, and information inside and outside the vehicle, and sends instructions via wire or wireless to the internal control unit 5021. The external control unit 5022 may be an application that is standardly installed in the vehicle, or an external application.

[0275] In this case, the external control unit 5022 may be linked, for example, to an input unit 507 that inputs on / off of sensing in the information acquisition unit 501 and selects various modes, a storage unit 504 that stores various information, and another control device (e.g., an air conditioner) 1003. When linked with another control device 1003, for example, information about an air conditioning system in the vehicle may be input to the external control unit 5022. The external control unit 5022 may also be provided with an output unit 505 such as a monitor, speaker, or air conditioning system, and the external control unit 5022 may output information acquired by the information acquisition unit 501, content corresponding to the information, etc. to each output unit 505.

[0276] Upon receiving instructions from the external control unit 5022, the internal control unit 5021 controls the odor presentation unit 503 to present an odor using an odor-generating cartridge 1 containing a designated odor, for example, from odors A to F provided in each odor-generating cartridge 1. In this case, the internal control unit 5021 may also send instructions to the airflow control unit in the airflow mechanism 506 to control the airflow source and the direction control unit (e.g., louvers, flaps, etc.), and use the airflow presentation unit to set the odor's reach distance and direction to a desired distance and direction. By implementing this specific example, it is possible to recognize the driving conditions, the occupant's condition, and information inside and outside the vehicle, and present an appropriate odor, which is expected to make each subject feel more comfortable. Note that the term "appropriate odor" here is a concept that includes an odor arbitrarily set for each subject.

[0277] 36 is a flowchart showing an example of operation using the odor presentation control system 500. First, a specific target selects a mode via the input unit 507 and turns the mode on (S8001). The mode selected here is not particularly limited, but in this specific example, for example, either an active mode or a relaxed mode can be selected and each mode can be turned on / off. The active mode may present an odor that is more exciting or thrilling, while the relaxed mode may present an odor that is more calming.

[0278] Upon receiving the input indicating that mode selection is on, the external control unit 5022 instructs the information acquisition unit 501 to perform sensing (S8002). Sensing here includes, for example, acceleration, G-value (particularly lateral G), and vital signs. In addition, the camera can recognize faces, and the direction control unit can present odors toward specific targets. Based on the results of sensing, the external control unit 5022 selects the type of odor appropriate to the situation and sends an instruction to the internal control unit 5021 to present the selected odor (S8003).

[0279] Furthermore, the external control unit 5022 may not only select the type of scent, but also determine appropriate conditions regarding the scent's reach, scent emission direction, scent intensity, scent emission rhythm (presentation rhythm), etc., and send instructions to the internal control unit 5021. Furthermore, the external control unit 5022 may also perform control of things other than scent, and for example, images, videos, sounds, etc. according to the situation may be presented to the subject from a monitor, speaker, etc., and a comprehensive sense of realism may be created through multimodal processing (S8004).

[0280] Next, the internal control unit 5021 presents an odor to a specific target using the odor presentation unit 503. At this time, the direction and amount of odor emission may be adjusted, and the blower mechanism 506 may be used as needed (S8005). Next, after the odor is presented, a predetermined time has elapsed, and the external control unit 5022 again instructs the information acquisition unit 501 to perform sensing, and determines whether the acceleration, G value (particularly lateral G), vital signs, etc. are below the threshold (S8006). If it is determined that they are below the threshold, the presentation of the odor is stopped (S8007). If it is determined that they exceed the threshold, the process returns to S8003.

[0281] Below, we will explain examples of scent presentation patterns in the flowchart shown in Figure 36. Note that in Examples 1 to 4 shown below, it is assumed that scents can be presented to specific targets by controlling the scent emission direction using the air blowing mechanism 506 through camera recognition.

[0282] [Example 1] Assume that, in the active mode ON state, the information acquisition unit 501 has obtained information that repeated acceleration and deceleration have occurred (e.g., three or more accelerations and decelerations within a predetermined time), a gyro of 1 G or more has been detected, and vital signs (e.g., heart rate) are rising. In this case, for example, the smell of burning tires may be presented to a specific target. Note that the stronger the G value, the more the amount of smell emitted may be increased. At the same time, it is also possible to perform a performance based on multimodal processing using braking sounds and video. Note that vital signs may also be measured for all humans or animals within the moving body.

[0283] [Example 2] With active mode ON, assume that the information acquisition unit 501 receives information that acceleration has continued for a predetermined period of time or more and that the engine speed has reached a predetermined rotational speed or more. In this case, for example, the scent of engine oil may be presented to a specific target. Note that the longer the acceleration time, the greater the amount of scent emitted. At the same time, it is also possible to perform a presentation based on multimodal processing of engine sounds and images.

[0284] [Example 3] Suppose that while the relaxation mode is ON, the information acquisition unit 501 detects sudden braking (e.g., deceleration above a threshold for a predetermined time) and obtains information that vital signs (e.g., heart rate) are rising. In this case, for example, a preferred scent or a calming scent may be presented to a specific target. Note that the higher the vital signs, the more scent may be emitted. At the same time, it is also possible to perform a performance based on multimodal processing using relaxing music and images. Note that vital signs may be measured for all humans or animals within the moving body.

[0285] [Example 4] When active mode or relaxation mode is ON, forward / reverse acceleration is detected by braking or accelerating. If acceleration is occurring, the odor is gradually changed from a weak odor to a strong odor, and then back to a weak odor. That is, the odor intensity may be changed based on the change in acceleration. Furthermore, if the acceleration is large, the change in odor intensity per unit time may also be increased. Alternatively, the odor intensity may remain the same, and the odor emission distance may be changed based on the change in acceleration from a position far from the face of a specific target to the vicinity of the target's face to a position far from the target's face. This allows for a pseudo-change in the odor intensity (strength) perceived by a specific target.

[0286] In addition to the above-described scents, this application example may also provide scents that correspond to the surrounding environment of the mobile object. Specifically, examples include, but are not limited to, the scents of flowers such as lavender, osmanthus, rose, and lily, the scent of the mountains, and the scent of the sea. Another example is acquiring information about the scenery outside from a camera, analyzing it in real time, and presenting scents that are linked to the scenery outside. In this case, the type of scent may be preset based on expected types (e.g., cypress, ginkgo, etc.). It is also possible to use a sensor to blend scents on an image or scent-by-scent basis. Furthermore, when leisure mode is selected, the device may be linked to a navigation system using GPS to guide the user to a route that allows them to enjoy more scents. When a driving course is selected, scents may be presented that correspond to the shape of the road along the driving course.

[0287] (5) Specific examples aimed at improving performance

[0288] This specific example aims to improve the performance of a mobile object. Specifically, for example, the odor can be efficiently diffused by understanding the installation location of the odor presentation unit 503 and the status of the air conditioning system in the mobile object. For example, the odor presentation control system 500 can be linked to the room air conditioning system, a fluid simulation can be displayed using images, control can be performed based on the results of AI analysis of information acquired by the information acquisition unit 501, or image recognition can be used to emit an odor in the direction of an obstacle that is likely to cause odor diffusion. In this case, the odor diffusion range, odor emission volume, etc. can be changed depending on the number of people or animals riding on the mobile object. If there are fewer people or animals riding on the mobile object, a narrower diffusion range and a smaller emission volume can be sufficient, which prevents unnecessary consumption of the odor-emitting cartridge 1 and leads to cost reduction.

[0289] Another example is the ability to switch between a personal space (narrow) mode and an entire space (wide) mode. For example, when the driver is sleepy, the personal space (narrow) mode is applied, and the scent is strongly presented only to the driver. On the other hand, when performing a spatial effect, the entire space (wide) mode is applied, and the scent is spread throughout the entire space. Note that switching between the personal space (narrow) mode and the entire space (wide) mode may be performed automatically or manually by the user via the input unit 507.

[0290] Furthermore, the strength of the scent can be selected from several levels, and can be controlled automatically or manually. For example, it is possible to automatically detect long-term or long-distance driving, and present a strong scent to stimulate the driver, especially when driving at a constant speed for a long time or long distance. In addition, to prevent habituation to the scent, it is possible to change the type of scent and control the strength of the scent presentation over a certain period of time.

[0291] Additionally, the odor presentation control system 500 may control the odor presentation conditions and whether or not to use the air blowing mechanism 506 and / or the deodorizing mechanism depending on the type and size of the moving object.

[0292] (6) Specific examples of added value

[0293] Below, specific examples of added value when the odor presentation control system 500 is used in a mobile object will be given.

[0294] (6-1) Example of added value 1

[0295] The scent is presented according to the temperature, humidity, etc. inside the vehicle. For example, when it is hot, a refreshing scent like menthol is presented. In this case, it may be linked to a navigation system or application, and the scent may be determined based on the weather, etc.

[0296] (6-2) Example of added value 2

[0297] The presenting of scents can help determine the seat one is sitting in on a moving object. For example, on an airplane, where it is difficult to know where one is sitting, the scent is linked to the target's seat and the scent that the target prefers, and seat information is conveyed to the target by presenting scents.

[0298] (6-3) Example of added value 3

[0299] When a sensor detects that a specific target is in a negative state, it presents an odor to return the target to a neutral to positive state. For example, if it detects that the target is irritated due to a fight in a moving vehicle, traffic jams, the vibrations and roars of an airplane, etc., it presents an odor with a calming effect. Also, if it detects that the target is in a tense or excited state while driving, it presents an odor with a calming effect or an odor that improves concentration. This can be implemented based on detection of the specific target by the information acquisition unit 501 with or without contact. Examples include measuring vital signs with a smartwatch, measuring vital signs with a sensor embedded in a seat, and measuring sweat rate by observing electrical resistance on the body surface, but the present technology is not particularly limited to these.

[0300] (6-4) Example 4 of added value

[0301] Physiological responses to scents are measured with sensors to estimate and measure relationships with others. For example, by visualizing a decrease or increase in heart rate after a scent is presented, it is possible to estimate whether the other person has an intimate relationship with a specific target, whether the other person is someone the user dislikes, whether the other person likes, or whether the other person has no particular feelings for the other person. Other measurements include the physical distance and physical positional relationship between the other person and the other person. Furthermore, by detecting a slowed response by detecting pupils after a scent is presented, fatigue from long-term or long-distance driving can be detected.

[0302] (6-5) Example 5 of added value

[0303] By presenting scents, communication can be achieved in situations where verbal or visual information is difficult. For example, when riding a bus, train, or airplane with strangers, scents can be presented only to the driver or supervisor to subtly communicate illness such as stomachache or headache.

[0304] (6-6) Example 6 of added value

[0305] By presenting scents that have the same direction as the temperature change caused by the air conditioner in a mobile vehicle, it is possible to soothe the body and alleviate psychological anxiety without significantly changing the temperature of the air conditioner. For example, when changing the temperature of the air conditioner to lower it, presenting the scent of peppermint or menthol makes it feel cooler without lowering the temperature too much.

[0306] (6-7) Example 7 of added value

[0307] In recent years, it has been known that odors are one of the causes of motion sickness. Therefore, controlling odors can eliminate motion sickness. It is said that the adoption of autonomous driving will further increase motion sickness, and there is a high possibility that the need for such technology will increase in the future. For example, the information acquisition unit 501 determines and predicts in advance whether a specific subject is experiencing motion sickness or is likely to experience motion sickness based on the movement of the vehicle and changes in biometric information, and promptly presents an odor, such as peppermint or lavender, that is believed to be effective against motion sickness. Alternatively, an odor preferred by the specific subject may be presented. In this case, the "vehicle" may include not only a private car but also a bus (especially one traveling long distances), a taxi, a ship, etc., but is not particularly limited in this technology.

[0308] (6-8) Example 8 of added value

[0309] An odor presentation spot is formed on a crowded train, bus, or other such location to alleviate the irritation of multiple specific targets. For example, by using the odor presentation control system 500, an odor is presented within a predetermined emission range for a predetermined time, then deodorized using a deodorizing mechanism, and the area is then changed and the same operation is performed again. This allows odor presentation spots to be easily formed in a chronological order (avoiding the generation of new stress due to the presentation of the same odor over a long period of time), and the presentation of odors to targets within the spot alleviates their irritation.

[0310] 9. Application Example 8 of the Odor Presentation Control System 500: Presentation of Odors in a Passenger Car

[0311] In this application example, among the above-mentioned moving objects, a passenger car is particularly focused, and the purpose is to efficiently present an odor inside the passenger car. Specifically, for example, the odor is presented to a specific target by using the wind from the air conditioner pre-installed in the passenger car.

[0312] Conventionally, passenger cars are often not equipped with devices that present odors, but in this application example, by attaching an odor presentation unit 503 that includes at least the odor-generating cartridge 1 to the vehicle externally or internally, an appropriate odor that suits the scene can be presented, thereby providing the user with effects such as increasing their concentration and waking them up, relieving drowsiness, and relaxing them.

[0313] When attaching the scent presentation unit 503 to an air conditioner in a passenger vehicle, there are no particular limitations, and examples include attaching the scent presentation unit 503 to the vicinity of the air conditioner's air outlet using a string or wire, incorporating the scent presentation unit 503 into the air conditioner, or attaching the scent presentation unit 503 to another item near the air conditioner (for example, a drink holder that is pre-installed in a passenger vehicle as shown in FIG. 37). Alternatively, the scent presentation unit 503 may be attached to two or more of these locations.

[0314] Furthermore, when attached to an air conditioner in a passenger car, the information acquisition unit 501 recognizes the position of the target's face, and the timing for delivering the scent is made known to the target by displaying it on the display unit of the car navigation system, a smartphone, etc., lighting up a lamp, or notifying the target by voice, and then by turning the face toward the air conditioner outlet only at that timing, the wind from the air conditioner can be used to present the scent to the target.

[0315] In this case, the odor presentation unit 503 simply delivers the odor-containing air to the air conditioner outlet (see the white arrow in Figure 37). If the subject feels uncomfortable when the air is blown onto their face, this can be resolved by, for example, setting the minimum amount of air discharge required to deliver the odor-containing air via the input unit 507, or shortening the discharge time of the odor-containing air (for example, setting the discharge time to within 2-3 seconds to 10 seconds).

[0316] FIG. 38 is a block diagram showing an outline of a case where part or all of the odor presentation control system 500 is installed in a passenger vehicle air conditioner. Note that in FIG. 38, some parts of the odor presentation control system 500 are omitted. In the block diagram shown in FIG. 38, an in-vehicle camera, a temperature sensor, and a reader for the odor-emitting cartridge 1 are used as the information acquisition unit 501, which recognize the position of the target's face, detect the temperature, and recognize the type of odor-emitting cartridge 1. A control unit 502 (not shown) controls the air conditioner by, for example, changing the direction of the air outlet to face the target's face in the case of wind direction, changing the air volume to produce a weak wind, and operating for several seconds in the case of operating time. Furthermore, the control unit 503, which includes at least the odor-emitting cartridge 1, controls the operating time by setting the discharge time to several seconds and selecting the type of odor-emitting cartridge 1.

[0317] In addition, various other controls may be performed, such as controlling the strength of the odor depending on the air volume of the air conditioner, or controlling the air flow speed and air volume depending on the distance from the air conditioner to the position of the face.

[0318] 10. Use of odor-related data in everyday life

[0319] Here, we will explain how adding scents (fragrances) to daily life can help achieve satisfaction in daily life.

[0320] Previous research has pointed to the interrelationship between taste and neurogastronomy. For example, humans are able to enjoy the taste of beef due to the interaction between the umami component inosinic acid and odor components. It can also be applied to functional foods such as reduced salt diets, where the smell of the sea enhances saltiness and the smell of vanilla enhances sweetness. Furthermore, associative learning between taste and taste can evoke memories based on childhood experiences and culture, which can affect the way each person perceives different tastes.

[0321] Furthermore, it has become clear in recent years that odors can be used medically to suppress stress, and the effects of odors can now be measured from vital signs such as body temperature, blood pressure, and heart rate, as well as stress markers in blood and saliva. However, because the main components of odors are often volatile, the amount of odor administered can be controlled using the odor presentation control system 500, odor presentation unit 503, odor generating cartridge 1, etc., as described in the present technology. In addition, it has been reported that odors are effective in preventing or improving dementia. For example, exposure to the odor of essential oils during sleep has significantly improved memory, and this is expected to be effective even for severely ill patients.

[0322] In other words, this technology is expected to be used not only for solutions to "special occasions" such as entertainment and medical examinations, but also for "ordinary" everyday activities such as eating, sleeping, and work. This will naturally add scents to each aspect of daily life, enriching daily life.

[0323] As mentioned above, smells are involved in every aspect of daily life. Therefore, by collecting and accumulating data on smells, the accumulated data on the effects and control of smells for each individual can be converted into big data, and by using AI for machine learning, it can be used to discover and develop further UX. For example, big data can be used to create scent recipes. Then, by providing feedback on the results of machine learning to each individual, scent recipes, scent effects, and scent control can be presented to each individual, which can lead to more effective and optimized cyclical scent presentations. For example, this could include presenting scents tailored to each individual, or scent subscriptions that track changes in the user's state and each scene.

[0324] Specifically, we propose below that by combining various sensors, for example, the senses can be stimulated more effectively and continuously in everyday life.

[0325] [Understanding User Status] To understand the user's status, the user may wear a wearable device equipped with various sensing functions, such as a ring-type, wristwatch-type, neckband-type, or headphone-type device. For example, in the case of a ring-type device, the user can wear it on any finger, and sensing (not limited to vital signs sensing) can be performed from there, thereby understanding the user's status. Furthermore, even if the device is not in contact with the user, the user's status may be understood by combining the above-mentioned environmental sensors, cameras, brightness sensors, infrared sensors, odor sensors, gas sensors, etc.

[0326] [Effect on Taste (Diet)] As mentioned above, taste is known to be related to smell. Therefore, here, we will provide a specific example of how the presentation of smells can improve meal satisfaction. The shape of the smell presentation unit 503 referred to here is not particularly limited as long as it can emit a smell. Examples include, but are not limited to, cup-shaped (see FIG. 39 , which has a mechanism for emitting a built-in smell from a discharge unit 14), plate-shaped, chopstick rest-shaped, trivet-shaped, pot-shaped, wine glass-shaped, fork-shaped, spoon-shaped, and knife-shaped devices that incorporate an smell-emitting cartridge 1 or the like and are used at the dinner table. Furthermore, these shapes may be designed to more efficiently present the smell to the user by taking into consideration the angle at which the smell is emitted, the position of the nose when eating and drinking, the timing of eating and drinking, and the like.

[0327] FIG. 40 is a flowchart illustrating the use of scents in mealtimes. A specific example will be described using the flowchart in FIG. 40 . For example, at the start of a meal, a user's blood glucose level is measured using the user's ring-shaped device (S1). Next, if the measurement results indicate that the user's blood glucose level is low or that the user is hungry (S2), an appetite-stimulating scent (e.g., ginger scent) is presented (S3). This scent may be presented, for example, when the user is hydrating. On the other hand, if the measurement results indicate that the user's blood glucose level is not low or that the user is not hungry, and that the user's blood glucose level is not high or the change in blood glucose level is not greater than a specified value (S4), a scent preferred by the user is presented (S5). On the other hand, if the measurement results indicate that the user's blood glucose level is high or the change in the user's blood glucose level is greater than a specified value (S4), an appetite-suppressing scent (e.g., grapefruit scent) is presented (S6).

[0328] In this way, linking taste and smell during mealtimes can lead to improved dietary functions such as reduced salt intake, and increased satisfaction with meals by stimulating appetite. Other expected effects include appetite suppression, allowing people to naturally eat the right amount of food, and providing meals that are appropriate for each individual's body without overdoing it.

[0329] [Linking with User's Condition (Work)] As mentioned above, vital signs are known to be related to odors. Therefore, here, we will provide a specific example of how presenting an odor can improve work efficiency and a sense of fulfillment. The form of the odor presenting unit 503 referred to here is not particularly limited as long as it can present an odor. Examples include, but are not limited to, a stationary diffuser incorporating an odor-emitting cartridge 1, a portable diffuser, a diffuser suspended from the ceiling, and a diffuser incorporated into a desktop or notebook PC. Furthermore, these forms may be designed to present the odor to the user more efficiently by taking into account the angle at which the odor is emitted, the position of the nose when working, the timing of work, and the like.

[0330] FIG. 41 is a flowchart showing the use of scents in a work setting. A specific example will be described using the flowchart in FIG. 41. For example, at the start of work, the user's concentration (e.g., vital signs, emotions (including measurements using vital signs), blink rate, etc.) is measured using the user's ring-shaped device (S7). The user's "emotion" here refers to feelings such as joy, sadness, anger, fear, and anxiety, and is a broad concept that refers to short-term responses consisting of physiological responses, behavioral responses, and subjective emotional experiences based on the evaluation of sensory stimuli.

[0331] Next, if the measurement results indicate that the user is relaxed (S8), it is measured whether the relaxed state continues for a long time (S9). Next, if the measurement results indicate that the user is not relaxed for a long time (S9), the process returns to S7. On the other hand, if the measurement results indicate that the user is relaxed for a long time (S10), a scent that supports concentration (such as the scent of rosemary) is presented (S10), and the process returns to S7.

[0332] Next, if the measurement results indicate that the user is not relaxed (S8), it is determined whether the user is concentrating. Next, if it is determined that the user is concentrating (S11), it is determined whether the state of concentration continues for a long period of time (S12). Next, if the measurement results indicate that the state of concentration has not continued for a long period of time (S12), the process returns to S7. On the other hand, if the measurement results indicate that the state of concentration has continued for a long period of time (S12), a relaxing scent (e.g., the scent of bergamot) is presented (S13), and the process returns to S7. Although not shown in the flowchart, ambient light, etc. may be controlled in conjunction with a brightness sensor, etc., to work more efficiently, such as by setting the lighting slightly darker when relaxing.

[0333] In this way, by linking the user's state with the scent in a work environment, it is possible to concentrate efficiently on work or relax appropriately while working. The balance between concentration and relaxation allows the user to continue working comfortably.

[0334] [Linkage with Video and Sound (Live Video Viewing Scene)] In recent years, technologies have been developed that link video and sound with scents to provide a more satisfying experience. Here, we will provide a specific example of how the user's video and sound experience can be improved by presenting scents. The form of the scent presenting unit 503 referred to here is not particularly limited as long as it can present a scent. Examples include, but are not limited to, a stationary diffuser incorporating a scent-emitting cartridge 1, a portable diffuser, and a ceiling-hanging diffuser. Furthermore, these forms may be designed to more efficiently present the scent to the user by taking into consideration factors such as the angle at which the scent is emitted, the position of the nose when watching the video, and the timing of watching the video.

[0335] FIG. 42 is a flowchart showing the use of scents in a scene where a live video is being viewed. FIG. 47 shows a UI used to control scents in a scene where a live video is being viewed. By using this UI, a user can present a scent appropriate for each live video to the viewer. A specific example will be described using the flowchart shown in FIG. 42. For example, at the start of a live video, a scent that will lift the user's spirits (e.g., the scent of rose) is presented (S14). Next, the user's emotions are measured using various devices and / or various sensors (S15). If the measurement results indicate that the user's emotions are not high (S16), the intensity of the scent is increased (S17). On the other hand, if the measurement results indicate that the user's emotions are high (S16), the live performance continues as is (S18).

[0336] For example, when a ballad is played, a calming scent (e.g., lavender, frankincense, etc.) is presented, and the scent is preset to match the progress of the live performance (S19). Next, for example, near the end of the live performance, the user's emotions are measured (S20). If the measurement results indicate that the user is not calm (not moved by the live performance) (S21), another calming scent (e.g., neroli) is presented (S22). If the user is determined to be calm (moved by the live performance) (S21), the live performance continues, or the live video ends (S23). Although not shown in the flowchart, ambient light, etc., may be controlled by linking with a brightness sensor, etc., to dim the lighting slightly during ballads.

[0337] In this way, when watching live video, it is possible to enhance the excitement of the live performance and experience deeper emotions at the highlights of the live performance. It is also expected to leave a bright and cheerful impression of the live performance and the performers.

[0338] 11. Optimization through data accumulation

[0339] Here, we will explain how to utilize accumulated data from sleep. First, sensing is performed on the user to measure the effects of scents. "Sensing" here refers not only to general sleep sensing, such as whether the user is sleeping well, but also to medical sensing, such as whether dementia is being prevented. By accumulating scent effects and user data, it is possible to present the user with the optimal scent using the big data already accumulated for each scenario. For example, sandalwood, which has the highest statistical effectiveness, can be used to recover from fatigue, lavender to relax, orange to promote restful sleep, and scents that have been shown to be effective against dementia for dementia prevention.

[0340] Furthermore, even after optimal data is presented, by continuing to measure the effect of the scent, the measurement results can be continuously fed back, allowing scents that match each individual to be presented. By utilizing big data accumulated from each individual, as described above, appropriate scents can be presented in various everyday situations, when watching movies, at live performances, etc. In this specification, "scent presentation" includes not only the type of scent, but also a broad concept such as the strength and direction of the scent.

[0341] FIG. 43 is a UI showing the change in a user's scent over the course of a week. It can be seen that by measuring vital signs, blood sugar levels, and sleep quality in this way and then discharging the lavender scent at the appropriate time, changes in the user's condition can be observed. FIG. 44 is a UI showing the condition of a user throughout the day. For example, the user's condition is measured in the morning, afternoon, and evening, and the measurement results are displayed to the user. The effectiveness of the discharged scent is then evaluated. As another example, the user's condition may be measured at predetermined intervals (e.g., every hour). The timing and cycle of the measurement can be set by the user as appropriate, or may be automatically set to a desired timing.

[0342] Figure 45 is a UI showing the change in a user's scent over the course of a month. In this way, a predetermined set of scents can be provided to the user for a certain period of time, allowing the user's condition to be checked. The measurement results are then accumulated for each individual, converted into big data, and subjected to machine learning using AI, which is then reflected again in determining the optimal scent to provide to the user. Figure 46 is a UI showing information about a certain scent set, and the user can check this screen to see which scent is currently being presented.

[0343] In this way, by using this technology, the scent can be emitted, the user's condition can be measured, data can be accumulated, big data can be built, and AI machine learning can be performed repeatedly to more effectively stimulate the sense of smell and provide the user with an effective UX.
