SUMMARY

Technical Problem

As described above, an odor is presented according to a video. However, even when an odor associated with a video is presented to a viewer of the video, the viewer may perceive a sense of discomfort. This discomfort may be due to the way the odor is presented.

The impression that a human perceives about an odor varies greatly depending on the way the odor is presented. For example, a human to whom an odor is injected by an injection device such as a spray perceives wind pressure at the same time as perception of the odor, and in addition, a time in which the human perceives the odor is short. On the other hand, for example, for an odor from a sprayed scent, a human perceives only the odor without perceiving wind pressure, and in addition, a time in which the human perceives the odor is long. The impression that the human perceives greatly differs between a local odor like the former and a drifting odor such as the latter. Thus, the way an odor is presented is considered to be an important factor in expression of the odor.

Therefore, an object of the present technology is to provide a technology for controlling an odor that is presented to a human.

1. First Embodiment (Odor Presentation Module)

(1) Description of First Embodiment

The odor presentation module according to the present technology includes a first opening that first airflow containing an odor exits and a second opening that second airflow exits, and the first opening and the second opening are provided so that movement of the first airflow exiting the first opening can be controlled by the second airflow. The odor presentation module according to the present technology can control movement of the first airflow containing the odor using the second airflow. Therefore, with the odor presentation module according to the present technology, it is possible to realize control of the odor contained in the first airflow to thereby realize various ways of presenting an odor. For example, the odor presentation module of the present technology can present an odor to a user using various expression methods such as a local odor and a drifting odor. Further, the odor presentation module of the present technology can reduce or eliminate an odor present outside the module using the second airflow.

The odor presentation module according to the present technology may be configured to be able to change the flow velocity of at least one of the first airflow and the second airflow. It is possible to realize more diverse odor expression by adjusting the flow velocity of each airflow.

An example of the way an odor is presented using an odor presentation module according to the present technology will be described with reference to FIG. 25. FIG. 25 is a conceptual diagram illustrating an example of an odor expressed by the odor presentation module according to the present technology.

A and B of FIG. 25 illustrate a relationship between the flow velocity of the airflow reaching the user from the odor presentation module of the present technology and time. FIG. 25 is intended for conceptual description and does not show an actual flow velocity or time.

In A of FIG. 25, an example of a case in which the second airflow is not generated and the first airflow containing an odor is generated at a specific time is illustrated. In the present example, the first airflow at flow velocity V₁ reaches the user at a specific time. When the first airflow is not generated, neither the first airflow nor the second airflow is generated, and the flow velocity is 0, that is, the user does not perceive wind pressure. A difference between the flow velocity when the first airflow is not generated and the flow velocity when the first airflow is generated is d₁, as illustrated in the figure. That is, this difference d₁ is a change in wind pressure that the user perceives together with the odor.

On the other hand, B of FIG. 25 illustrates an example in which the first airflow containing an odor is generated at a specific time while the second airflow is generated. In the present example, second airflow at flow velocity V₂ is always generated. Accordingly, when the first airflow is not generated, the user always perceives wind pressure at the flow velocity V₂. The first airflow at the flow velocity V₁ is generated only when the odor presentation is necessary. Here, because the user is always receiving the wind pressure at the flow velocity V₂, a change in the wind pressure felt by the user together with the odor is a difference d₂ between V₁ and V₂.

In the case of A of FIG. 25, the user that the first airflow has reached perceives the odor and also perceives large change in wind pressure. Therefore, it is possible to express, for example, a local odor (or a suddenly generated odor) by controlling the first airflow and the second airflow as illustrated in A of FIG. 25.

On the other hand, in the case of B of FIG. 25, the user that the first airflow has reached perceives the odor, but a change in wind pressure felt by the user is smaller than in the case of A of FIG. 25. It is possible to express, for example, a drifting odor by controlling the first airflow and the second airflow as illustrated in B of FIG. 25.

Thus, the odor presentation module of the present technology enables both expression of a local odor and expression of a drifting odor.

Further, for example, it is possible to change a concentration of the odor component in the airflow reaching the user by adjusting the flow velocity V₁ of the first airflow containing the odor and/or the flow velocity V₂ of the second airflow. This makes it possible to change intensity of the odor reaching the user, for example.

The olfactory display described in PTL 1 can express a local odor as illustrated in A of FIG. 25, for example, but cannot express a drifting odor. Therefore, for example, when the olfactory display is used for odor presentation linked to a video, scenes in which the odor can be presented are limited.

As described above, the odor presentation module according to the present technology can deliver the odor to the user in various presentation methods. It is possible to express not only a local odor but also an odor drifting in a space, for example. Further, the odor present in the space can be recovered. Therefore, when the odor presentation module according to the present technology is used for odor presentation linked to a video, it is possible to realize odor expression suitable for more scenes.

Further, an aspect in which the odor presentation module according to the present technology is used is not limited to the odor presentation linked to the video. For example, the odor presentation module of the present technology can also be used for odor presentation linked to an experience (for example, an attraction in an amusement park or a play in a theater) of the user. The odor presentation module according to the present technology can be used for various types of odor expression according to content of a video or experience, and can perform, for example, spot (local) odor expression or drifting odor expression.

C and D in FIG. 25 indicate ranges that airflow exiting the odor presentation module of the present technology reaches. FIG. 25 is intended for conceptual description and does not show an actual range.

C in FIG. 25 illustrates an example in which the second airflow is not generated and only the first airflow is generated. In the present example, because only the first airflow is generated, a range that the airflow reaches is, for example, a range A₁ that the first airflow reaches.

On the other hand, D in FIG. 25 illustrates an example of a case in which the same first airflow as in the case of FIG. 25C is generated from the inside of the second airflow while the second airflow is generated. In the present example, because the second airflow and the first airflow are generated at the same time, a range that the first airflow reaches can be expanded by the second airflow. For example, when the range that the second airflow reaches is A₃, the range that the first airflow reaches is expanded by the second airflow to become an area A₂. It is possible to further adjust the range that the first airflow reaches, for example, by adjusting the flow velocity or direction of the second airflow.

Thus, with the odor presentation module according to the present technology, it is possible to adjust a range that the odor reaches.

Further, a range A₂ that the first airflow reaches in D of FIG. 25 is wider than the range A₁ in C of FIG. 25. Because the range that the first airflow containing the odor reaches is wide, it becomes difficult to specify a place from which the first airflow is emitted (that is, a position of the odor presentation module). This is useful, for example, in a case in which an odor generation source is not desired to be specified for attraction participants in an attraction such as an amusement park.

Further, because the first airflow containing the odor reaches a wider range, it is possible to present the odor to the user even in a case in which a position of a nose of the user is shifted.

As described above with reference to FIG. 25, with the odor presentation module according to the present technology, it is possible to adjust the change in wind pressure felt by the user together with the odor and/or the range that the odor reaches. This makes it possible for the odor to be delivered to the user using any of various presentation ways.

Further, the odor presentation module of the present technology can also perform control of the odor as follows using the second airflow.

For example, in a case in which the first airflow containing an odor has stayed near the first opening or near the nose of the user, it is possible to curb the staying using the second airflow. This makes it possible to reduce or eliminate the odor recognized by the user.

Further, a case in which the presentation of the odor to the user is desired to be stopped at a specific timing is assumed. In this case, only the second airflow exits the second opening from the odor presentation module of the present technology, making it possible to blow the odor component from the vicinity of the nose of the user to thereby stop the presentation of the odor. Alternatively, the second airflow entering the odor presentation module from the second opening is generated so that the odor component may be recovered into the odor presentation module. This makes it possible to reduce or eliminate the odor at a specific timing.

Thus, not only odor control from the viewpoint of presentation of an odor but also odor control from the viewpoint of reduction or elimination of an odor can be realized by the second airflow.

The odor presentation module according to the present technology may include a first airflow generation device, and an odor carrying portion that carries the odor, and may be configured such that the airflow generated by the first airflow generation device and the odor included in the odor carrying portion form the first airflow.

For example, the odor presentation module may be configured such that the first airflow is generated by the airflow generated by the first airflow generation device passing through the odor carrying portion. The first airflow exits the first opening.

Alternatively, the odor presentation module according to the present technology may be configured such that the first airflow containing an odor is formed by the airflow generated by the first airflow generation device that exits the first opening and then comes into contact with the odor carrying portion.

Further, in the odor presentation module according to the present technology, the odor carrying portion that carries the odor and the first opening may be integrated. For example, the first opening may be provided in the odor carrying portion. For example, the first opening may be provided in a cartridge described below.

Further, the odor presentation module according to the present technology may further include a second airflow generation device, and the second airflow generation device may generate the second airflow. The second airflow exits the second opening.

Thus, the first airflow and the second airflow exiting the first opening and the second opening may be generated. More specific examples of components for generating these two airflows will be described below in (2) to (10).

Further, the odor presentation module according to the present technology may include, for example, an odor-containing airflow generation unit and a control airflow generation unit that controls the odor containing airflow generated by the odor-containing airflow generation unit. The odor-containing airflow generation unit may include a first airflow generation device, an odor component carrying portion through which airflow generated by the first airflow generation device passes, and a first opening that first airflow containing an odor formed by passing through the odor component carrying portion exits. The control airflow generation unit may include a second airflow generation device, and a second opening that second airflow generated by the second airflow generation device exits.

In this embodiment, preferably, the first opening and the second opening may be provided so that movement of the first airflow exiting the first opening can be controlled by the second airflow.

In the present technology, preferably, the odor presentation module may be configured such that the flow velocity at a position 10 cm forward in a traveling direction of the first airflow from the first opening (a direction passing through a center of an opening surface of the first opening and perpendicular to the opening surface) in a case in which the control airflow generation unit is operated and the odor-containing airflow generation unit is operated can be set to equal to or smaller than twice the flow velocity at the position in a case in which the control airflow generation unit is operated and the odor-containing airflow generation unit is not operated. This makes it possible to perform the control of the first airflow using the second airflow more effectively.

In the present technology, preferably, the odor presentation module may be configured such that directivity of the odor-containing airflow generated when the odor-containing airflow generation unit and the control airflow generation unit are simultaneously operated is lower than directivity of the odor-containing airflow generated when the odor-containing airflow generation unit is operated and the control airflow generation unit is not operated. Accordingly, for example, the range reached by the first airflow is expanded by the second airflow.

(2) First Example of First Embodiment (Example of Odor Presentation Module)

Hereinafter, an example of the odor presentation module according to the present technology will be described with reference to FIG. 1A. FIG. 1A is a schematic diagram of a configuration example of the odor presentation module according to the present technology.

As illustrated in FIG. 1A, an odor presentation module 100 includes an odor-containing airflow generation unit 109, and a control airflow generation unit 119 that controls odor-containing airflow generated by the odor-containing airflow generation unit 109.

The odor-containing airflow generation unit 109 includes a first airflow generation device 101, a flow path 102 having one end at which the first airflow generation device 101 is provided, an odor carrying portion 103 provided in the flow path 102, and a first opening 104 that is the other end of the flow path 102. These components form first airflow A1 containing an odor.

The control airflow generation unit 119 includes a second airflow generation device 111, a flow path 112 having one end to which the second airflow generation device 111 is connected, and a second opening 113 that is the other end of the flow path 112. These components form second airflow B1. The second airflow B1 controls the first airflow A1 containing an odor.

The first opening 104 is inside the second opening 113. That is, the first opening 104 and the second opening 113 are provided so that movement of the first airflow A1 exiting the first opening 104 can be controlled by the second airflow B1.

Hereinafter, these components will be described in greater detail.

The first airflow generation device 101 generates airflow flowing in the flow path 102 from the first airflow generation device 101 to the first opening 104. The first airflow generation device 101 may be, for example, an air pump, and more specifically, a diaphragm pump. The air pump may be a diaphragm pump including a piezoelectric element or a motor.

The first airflow generation device 101 is preferably configured to be able to adjust the flow velocity of the first airflow A1. For example, the first airflow generation device 101 is configured to be able to change the flow velocity of the first airflow A1 stepwise or continuously. This makes it possible to realize more types of odor expression as compared with the case of a device that generates the first airflow A1 at only one flow velocity.

The flow path 102 has the one end to which the first airflow generation device 101 is connected, and the other open end that is the first opening 104. A shape of a cross section of the flow path 102 (a cross section in a direction perpendicular to an axis of the flow path) may be, for example, a circle, an ellipse, or a rectangle (a square), and may be appropriately selected by those skilled in the art.

The odor carrying portion 103 imparts an odor to the airflow generated by the first airflow generation device 101. The odor carrying portion 103 may be provided at any position inside the flow path 102, and more preferably, the odor carrying portion 103 is provided so that the airflow generated by the first airflow generation device 101 passes through the odor carrying portion 103. For example, the odor carrying portion 103 may include an inlet 105 through which the airflow generated by the first airflow generation device 101 enters the odor carrying portion 103, and an outlet 106 through which the airflow passing through the odor carrying portion 103 exits the odor carrying portion 103. An odor can be imparted to the airflow while the airflow entering the odor carrying portion 103 from the inlet 105 passes through the odor carrying portion 103 and exits the outlet 106. More specifically, a volatile gaseous odor component may be included in the airflow. A position at which the odor carrying portion is provided may be, for example, a position closer to the first opening 104 in the flow path 102 than the first airflow generation device 101.

Further, an opening and closing mechanism or a check valve for controlling the passage of the airflow may be provided at the inlet 105 through which the airflow generated by the first airflow generation device 101 enters the odor carrying portion 103.

Further, an opening and closing mechanism or a check valve for controlling the passage of the airflow may be provided at the outlet 106 that the first airflow containing an odor exits from the odor carrying portion 103. Alternatively, an opening and closing mechanism or a check valve for controlling the passage of airflow may be provided in the first opening 104.

Thus, in the present technology, the opening and closing mechanism or the check valve for controlling the passage of the airflow may be provided in any one or both of the inlet through which the airflow generated by the first airflow generation device enters the odor carrying portion, and the outlet or the first opening through which the first airflow containing an odor exits the odor carrying portion.

It is possible to curb odor leakage from the odor carrying portion using these opening and closing mechanisms or the check valve.

The odor carrying portion 103 may include, for example, a fragrance, and may include, more specifically, a liquid fragrance or a solid fragrance. An odor component contained in a fragrance (particularly a liquid fragrance or a solid fragrance) is imparted to the airflow generated by the first airflow generation device 101, and the first airflow A1 containing the odor is formed.

The liquid fragrance may be included in the odor carrying portion 103 in a state in which the liquid fragrance is impregnated in a fragrance carrier, for example. A shape of the fragrance carrier may be, for example, a spherical shape, a square shape, a triangular shape, or a cylindrical shape. A material of the fragrance carrier may be, for example, calcium silicate, silica gel, rock wool, diatomaceous earth, zeolite, peat, charcoal, vermiculite, bentonite, pearlite, carbon nanotubes, activated charcoal, natural fiber (for example, cotton or rayon), or felt made by processing fibers.

The solid fragrance may be a solid substance obtained by solidifying a liquid fragrance using, for example, a gelling agent, or may be a solid material that emits an odor, such as a piece of wood that emits an odor.

Further, the odor carrying portion 103 may include a deodorant instead of the liquid fragrance or the solid fragrance.

The fragrance included in the odor carrying portion 103 may be, for example, a natural fragrance or a synthetic fragrance. The odor carrying portion 103 may include one fragrance or may include a combination of a plurality of fragrances.

Preferably, in the odor presentation module according to the present technology, the odor carrying portion may be configured as a cartridge. That is, the odor carrying portion may be configured to be replaceable. For example, a portion 120 of the odor presentation module indicated by a dotted line including the odor carrying portion 103 and the first opening 104 may be configured to be replaceable, as illustrated in FIG. 1B. Alternatively, only the odor carrying portion 103 may be configured to be replaceable. Alternatively, the odor carrying portion 103, the first opening 104, and a part or all of the flow path 102 may be configured to be replaceable.

The replaceable odor carrying portion makes it possible to reuse a part of the odor presentation module other than the cartridge by replacing the cartridge, for example, when the odor component included in the odor carrying portion runs out or when the user wishes to change a type of odor component included in the odor carrying portion.

The first opening 104 may be arranged inside the second opening 113, for example, as illustrated in FIG. 1A. This makes it easy to perform control using the second airflow B1 of the first airflow A1 exiting the first opening 104.

The first opening 104 is an outlet that the first airflow A1 containing an odor exits to the outside of the odor presentation module 100. A shape of an opening surface of the first opening 104 may be, for example, a circle, an ellipse, or a rectangle (square).

When the shape of the opening surface is a circle or ellipse, a diameter or long diameter may be, for example, 0.1 mm to 5 mm, particularly, 0.2 mm to 3 mm, more particularly, 0.3 mm to 2 mm, and more particularly, 0.5 mm to 1.5 mm. When the shape of the opening surface is a square or a rectangle, one side of the square or the long side of the rectangle may be, for example, 0.08 mm to 4 mm, particularly, 0.16 mm to 2.4 mm, more particularly, 0.24 mm to 1.6 mm, and more particularly, 0.4 mm to 1.2 mm.

With such sizes, it is possible to operate the first airflow generation device 101 to emit the first airflow A1 containing an odor from the first opening 104 to the outside of the odor presentation module 100 only when necessary, and to prevent the odor included in the odor carrying portion 103 from exiting the odor presentation module 100 in other cases.

A size of a cross section of the first opening 104 (particularly, a size of the shape of the opening surface of the first opening 104) may be smaller than a size of a cross section of the flow path 102 from the outlet 106 of the odor carrying portion 103 to directly before the first opening 104. For example, the size of the cross section of the first opening 104 and the size of the cross section of the flow path 102 from the outlet 106 of the odor carrying portion 103 to directly before the first opening 104 can be set so that the first airflow A1 is injected from the first opening 104. Thus, in an embodiment of the present technology, the odor presentation module (particularly, the odor-containing airflow generation unit) may be configured such that the first airflow containing an odor is injected from the first opening.

The first opening 104 may be in front of the second airflow generation device 111 in a traveling direction of the second airflow B1. For example, the opening surface of the first opening 104 may be on the same plane as an opening surface of the second opening 113, or may be in front of the plane in the traveling direction of the second airflow B1. With such a disposition, it is possible to prevent the odor component contained in the first airflow A1 from adhering to a wall surface of the flow path 112 through which the second airflow B1 flows.

The first airflow A1 emitted from the first opening 104 is airflow containing an odor, and in particular, airflow containing an odor component included in the odor carrying portion 103. For example, the first airflow A1 may be airflow of a mixture of the odor component and air in a space in which the odor presentation module is placed. The first airflow A1 emitted from the first opening 104 may be, particularly, airflow formed by injection from the first opening 104, and may be, for example, directional airflow.

As illustrated in FIG. 1A, the flow path 102 including the odor carrying portion 103 may be provided inside the flow path 112 having the one end at which the second airflow generation device 111 is provided. This makes it easy to perform control of the first airflow A1 using the second airflow B1. This also makes it easy to perform the presentation of the drifting odor.

The second airflow generation device 111 forms airflow that flows in the flow path 112 in a direction from the second airflow generation device 111 to the second opening 113. The second airflow generation device 111 may form the second airflow B1 exiting the second opening 113.

The second airflow generation device 111 may be configured to also be able to form airflow flowing in an opposite direction. That is, the second airflow generation device 111 may be configured to be able to reverse a direction of airflow that is generated. Thus, the odor presentation module according to the present technology may be configured to change a direction of the second airflow to a direction into the second opening. This makes it possible to perform recovery of the odor component and to perform odor control such as reducing or eliminating the odor.

The second airflow generation device 111 may be, for example, a blowing device. More specifically, examples of the blowing device may include an axial fan, a blower fan, and a centrifugal fan, and particularly, the blowing device is an axial fan. For example, the odor presentation module 1500 according to the present technology may include an axial fan 1501 as the second airflow generation device, as illustrated in A of FIG. 23.

Alternatively, the blowing device may be a combination of a diaphragm pump, particularly, a diaphragm pump using a piezoelectric element or a motor (for example, a microblower) and an airflow expansion mechanism. The blowing device may be configured such that the airflow generated by the diaphragm pump is expanded by the airflow expansion mechanism and flows through the flow path. For example, the odor presentation module 1550 according to the present technology may be a combination of a diaphragm pump 1502 and an airflow expansion mechanism 1503 as the second airflow generation device, as illustrated in B of FIG. 23.

Each of the odor presentation modules 1500 and 1550 illustrated in FIG. 23 includes two odor-containing airflow generation units 1504. Thus, the odor presentation module according to the present technology may include one odor-containing airflow generation unit, or may include a plurality of (for example, 2 to 10, and particularly, 2 to 6) odor-containing airflow generation units.

The second airflow B1 generated by the second airflow generation device 111 may be airflow including the air itself in the space in which the odor presentation module 100 is placed, or may be airflow including air obtained by any other component being mixed with the air in the space. Preferably, the second airflow B1 is the air itself in the space in which the odor presentation module 100 is placed. This makes it easier to perform control of the presentation of the odor of the first airflow A1. For example, the second airflow B1 may be odorless air.

The second airflow generation device 111 is preferably configured to be able to adjust the flow velocity of the second airflow B1. For example, the second airflow generation device 111 is configured to be able to change the flow velocity of the second airflow B1 stepwise or continuously. This makes it possible to realize more types of odor expression as compared with the case of a device that generates the second airflow B1 at only one flow velocity.

The flow path 112 has one end to which the second airflow generation device 111 is connected, and the other end that is open and is the second opening 113. A shape of a cross section of the flow path 112 (a cross section in a direction perpendicular to an axis of the flow path) may be, for example, a circle, an ellipse, or a rectangle (a square), and may be appropriately selected by those skilled in the art. A size of the cross section of the flow path 112 through which the second airflow B1 flows is preferably larger than the size of the cross section of the flow path 102 through which the first airflow A1 flows.

The flow path 102 through which the first airflow A1 flows is provided inside the flow path 112 through which the second airflow B1 flows. Thus, the odor presentation module according to the present technology includes a first flow path through which the first airflow flows, and a second flow path through which the second airflow flows, and the first flow path may be provided inside the second flow path.

The second opening 113 is an opening that the second airflow B1 formed using the second airflow generation device 111 exits. An area of the opening surface of the second opening 113 is preferably larger than an area of the opening surface of the first opening 104. For example, the area of the opening surface of the second opening 113 may be 3 to 1000 times, particularly 5 to 500 times, and more particularly, 10 to 200 times the area of the opening surface of the first opening 104. This makes it easier to perform control of the first airflow using the second airflow.

A shape of the opening surface of the second opening 113 may be, for example, a circle, an ellipse, or a rectangle (square). When the shape of the opening surface is a circle or ellipse, a diameter or long diameter may be, for example, 5 mm to 1000 mm, particularly 7 mm to 500 mm, and more particularly 10 mm to 100 mm. When the shape of the opening surface is a square or rectangle, one side of the square or a long side of the rectangle may be, for example, 5 mm to 1000 mm, particularly 7 mm to 500 mm, and more particularly 10 mm to 100 mm.

As illustrated in FIG. 1A, the second airflow generation device 111 may be disposed behind the first opening 104 that the first airflow A1 containing an odor exits (behind a position on an axis of the first opening 104 when a traveling direction of the first airflow A1 is the axis). Alternatively, the second airflow generation device 111 may be located in front of the first opening 104.

Preferably, as illustrated in FIG. 1A, the second airflow generation device 111 is disposed behind the first opening 104 that the first airflow A1 containing an odor exits. This makes it possible to prevent the odor component contained in the first airflow A1 containing an odor from adhering to the second airflow generation device 111 in a case in which the second airflow generation device 111 emits the second airflow B1 from the second opening 113.

In the odor presentation module 100 described above, the movement of the first airflow A1 exiting the first opening 104 can be controlled by the second airflow B1

For example, it is possible to generate the first airflow A1 while continuously generating the second airflow B1 exiting the second opening 113, to thereby present, for example, the drifting odor to the user. It is possible to increase or decrease a flow rate (air volume) of the second airflow B1, to thereby change a degree of odor of the first airflow A1. Further, it is possible to stop the generation of the second airflow B1, to thereby generate a local odor due to the first airflow A1.

Further, it is possible to generate the second airflow B1 entering the odor presentation module from the second opening 113, to thereby recover the first airflow A1 containing an odor. For example, it is possible to recover the odor emitted to the outside of the odor presentation module. This makes it possible to decrease a degree of the odor recognized by the user, or to prevent the user from recognizing the odor.

For the odor presentation module 100 illustrated in FIG. 1, the first opening 104 and the second opening 113 may be provided on an outer surface of the odor presentation module 100. This makes it possible for the first airflow A1 and the second airflow B1 to come into contact with each other outside the odor presentation module 100. Thus, the odor presentation module of the present technology may be configured such that the first airflow and the second airflow come into contact with each other outside the odor presentation module.

As described above, the odor presentation module according to the present technology may include, for example, the odor-containing airflow generation unit, and the control airflow generation unit that controls the odor-containing airflow generated by the odor-containing airflow generation unit. The odor-containing airflow generation unit may include a first airflow generation device, an odor component carrying portion through which airflow generated by the first airflow generation device passes, and a first opening that first airflow containing an odor formed by passing through the odor component carrying portion exits. The control airflow generation unit may include a second airflow generation device, and a second opening that second airflow generated by the second airflow generation device exits.

(3) Second Example of First Embodiment (Example of First Airflow Generation Device)

Another example of the first airflow generation device according to the present technology will be described with reference to FIGS. 2 to 4. FIG. 2 is a diagram illustrating a case in which an unnecessary airflow is generated in the first airflow generation device according to the present technology. FIG. 3 is a schematic diagram of the first airflow generation device of the other example.

In order to form a state in which the user perceives only airflow without perceiving an odor, it is conceivable to operate the second airflow generation device 111 without operating the first airflow generation device 101. In order to form the above state, it is required to reliably prevent the odor from exiting the module from the first opening 104. However, with the generation of the second airflow B1 using the second airflow generation device 111, the odor may exit the module from the first opening 104 even when the first airflow generation device 101 is not operated. It is considered that this is caused, for example, by a gap being present in a portion in which the first airflow generation device 101 and the flow path 102 are connected, or by the first airflow generation device 101 having a structure in which a gap from the outside of the module to the inside of the flow path 102 is included. That is, due to the presence of such a gap, the generation of the second airflow B1 using the second airflow generation device 111 can induce generation of airflow in the flow path 102 at the time of stopping of an operation of the first airflow generation device 101.

For example, as illustrated in FIG. 2, when the odor presentation module 100 is actually used, in a case in which there is a gap in a portion in which the first airflow generation device 101 and the flow path 102 of the odor-containing airflow generation unit 109 are connected, the second airflow generation device 111 is operated even when the first airflow generation device 101 is not operated, so that airflow (indicated by a dotted line in FIG. 2) is generated in the flow path 102 and an odor is emitted at an unintended timing. Further, in FIG. 2, the first airflow generation device 101 is shown to be separated from the flow path 102, and this is intended to emphasize and show the presence of the gap, and does not show a structure in an actual device.

The emission of the odor at the unintended timing as described above is not desirable, and may lead to a loss of the fragrance included in the odor carrying portion 103.

Further, the same problem as described above can occur in a case in which the opening 104 of the flow path 102 is provided in an open structure in the flow path 112 of the control airflow generation unit 119 even when there is no gap in the flow path 102.

Therefore, in a second example of the present embodiment, a configuration example of the first airflow generation device that curbs generation of airflow in the flow path 102 of the odor-containing airflow generation unit 109 when the second airflow generation device 111 is operated at a time when the operation of the first airflow generation device stops is shown.

As illustrated in FIG. 3, a first airflow generation device 101-1 in the odor-containing airflow generation unit 109 includes a discharge port 121 formed on the side communicating with the flow path 102 and discharging the first airflow, and an intake port 122 for taking in the first airflow.

The discharge port 121 and the intake port 122 communicate with an internal space of the first airflow generation device 101-1, and the flow path 102. An opening and closing valve 123 that blocks the discharge port 121, and an opening and closing valve 124 that blocks the intake port 122 are provided inside the first airflow generation device 101-1.

Further, a diaphragm 125 at positions facing the opening and closing valve 123 and the opening and closing valve 124, and a piezoelectric element 126 connected to the diaphragm 125 are provided inside the first airflow generation device 101-1. By the diaphragm 125 having the piezoelectric element 126 operated as a pump, first airflow is generated and the opening and closing valve 123 and the opening and closing valve 124 are opened or closed.

The odor presentation module 100 using the first airflow generation device 101-1 for the odor-containing airflow generation unit 109 has a structure in which there is no gap in the flow path 102 of the odor-containing airflow generation unit 109, and closes the opening and closing valve 123 and the opening and closing valve 124 to block the discharge port 121 and the intake port 122 at the time of stopping of an operation of the first airflow generation device 101-1.

Therefore, the odor presentation module 100 of the present example can curb generation of airflow in the flow path 102 even when the second airflow generation device 111 is operated at the time of stopping of the operation of the first airflow generation device 101-1. This makes it possible for the odor presentation module 100 of the present example to curb the emission of the odor from the flow path 102 at an unintended timing or a loss of a fragrance included in the odor carrying portion 103.

Next, a first airflow generation device according to the modification example of the present example will be described with reference to FIG. 4. FIG. 4 is a schematic diagram of the first airflow generation device of the modification example. FIG. 4A illustrates a case in which an operation of the first airflow generation device is ON. FIG. 4B illustrates a case in which the operation of the first airflow generation device is OFF.

As illustrated in FIGS. 4A and 4B, the first airflow generation device 101-2 in the odor-containing airflow generation unit 109 includes a discharge port 131 for discharging the first airflow, which is formed on the side communicating with the flow path 102, and two intake ports 132 for taking in the first airflow, which is formed on side opposite to a side communicating with the flow path 102. The numbers of the discharge port 131 and the intake port 132 may be one or plural. Further, the discharge port 131 and the intake port 132 may be disposed at positions facing each other or at other positions.

The discharge port 131 communicates an internal space of the first airflow generation device 101-2 and the flow path 102. Further, the discharge port 131 and the two intake ports 132 communicate with each other in the internal space of the first airflow generation device 101-2. Further, a diaphragm 125 extending in a direction substantially orthogonal to a direction in which the discharge port 131 and the intake port 132 face each other, and a piezoelectric element 126 connected to the diaphragm 125 are provided inside the first airflow generation device 101-2.

An opening and closing valve 133 that blocks the two intake ports 132 is provided on the side in which the intake ports 132 of the first airflow generation device 101-2 are formed. As illustrated in FIG. 4A, when an operation of the first airflow generation device 101-2 is ON, the opening and closing valve 133 is opened to separate from the two intake ports 132, and the first airflow flows from the intake port 132 to the discharge port 131. On the other hand, as illustrated in FIG. 4B, when the operation of the first airflow generation device 101-2 is OFF, the opening and closing valve 133 is closed to block the two intake ports 132, and the first airflow does not flow from the intake port 132 to the discharge port 131.

The odor presentation module 100 using the first airflow generation device 101-2 for the odor-containing airflow generation unit 109 has a structure in which there is no gap in the flow path 102 of the odor-containing airflow generation unit 109, and closes the opening and closing valve 133 to block the two intake ports 132 at the time of stopping of the operation of the first airflow generation device 101-2.

Therefore, the odor presentation module 100 of the modification example of the present example can curb generation of airflow in the flow path 102 even when the second airflow generation device 111 is operated at the time of stopping of the operation of the first airflow generation device 101-2. This makes it possible for the odor presentation module 100 of the modification example of the present example to curb the emission of the odor from the flow path 102 at an unintended timing or a loss of a fragrance included in the odor carrying portion 103.

(4) Third Example of First Embodiment (Example of Odor Presentation Module)

Another example of the odor presentation module according to the present technology will be described with reference to FIGS. 5 to 7. FIGS. 5A and 5B are schematic views of the odor presentation module of the other example, respectively.

A third example of the present embodiment shows a configuration example of the odor presentation module that curbs generation of the airflow in the flow path of the odor-containing airflow generation unit when the second airflow generation device 111 is operated at a time when the operation of the first airflow generation device stops.

As illustrated in FIG. 5A, the odor presentation module 100-1 includes an odor-containing airflow generation unit 109-1, and a control airflow generation unit 119 that controls an odor-containing airflow generated by the odor-containing airflow generation unit 109-1, as in the first example.

The odor-containing airflow generation unit 109-1 includes the first airflow generation device 101, the flow path 102 having one end at which the first airflow generation device 101 is provided, the odor carrying portion 103 provided in the flow path 102, and the first opening 104 that is the other end of the flow path 102. These components form the first airflow containing an odors.

Further, in the flow path 102, a solenoid valve 141 that is an example of an opening and closing valve is provided between the first airflow generation device 101 and the odor carrying portion 103. The solenoid valve 141 can be electrically controlled so that solenoid valve 141 is opened or closed, and blocks the flow path 102 at the time of stopping of the operation of the first airflow generation device 101.

As illustrated in FIG. 5B, the odor presentation module 100-2 includes an odor-containing airflow generation unit 109-2, and a control airflow generation unit 119 that controls the odor-containing airflow generated by the odor-containing airflow generation unit 109-2, similar to FIG. 5A.

The odor-containing airflow generation unit 109-2 includes the first airflow generation device 101, the flow path 102 having one end at which the first airflow generation device 101 is provided, the odor carrying portion 103 provided in the flow path 102, and the first opening 104 that is the other end of the flow path 102.

Further, a solenoid valve 142 is provided between the odor carrying portion 103 and the first opening 104 in the flow path 102. The solenoid valve 142 blocks the flow path 102 at the time of stopping of the operation of the first airflow generation device 101, similar to the solenoid valve 141. The solenoid valve is not limited to the disposition in the present example, and may be disposed at any position in the flow path 102 as long as the flow path 102 can be blocked at the time of stopping of the operation of the first airflow generation device 101.

The first airflow generation device 101, the flow path 102, the odor carrying portion 103, and the first opening 104 included in the odor-containing airflow generation unit 109-1 and the odor-containing airflow generation unit 109-2 may be the same as the respective components included in the odor-containing airflow generation unit 109 described in (2) above, and the description thereof also applies to the present example. Further, the respective components included in the control airflow generation unit 119 may be the same as the respective components included in the control airflow generation unit 119 described in (2) above, and the description thereof also applies to the present example.

The odor presentation module 100-1 including the odor-containing airflow generation unit 109-1 or the odor presentation module 100-2 including the odor-containing airflow generation unit 109-2 closes the solenoid valve 141 or the solenoid valve 142 to block the flow path 102 at the time of stopping of the operation of the first airflow generation device 101.

Therefore, in the odor presentation module 100-1 and the odor presentation module 100-2, even when there is a gap, for example, between the first airflow generation device 101 and the flow path 102, it is possible to curb generation of airflow in the flow path 102 when the second airflow generation device 111 is operated at the time of stopping of an operation of the first airflow generation device 101. This makes it possible for the odor presentation module 100-1 and the odor presentation module 100-2 to curb the emission of the odor from the flow path 102 at an unintended timing or a loss of a fragrance included in the odor carrying portion 103.

Next, an odor presentation module according to a modification example of the present example will be described with reference to FIG. 6. FIG. 6 is a schematic diagram of the odor presentation module of the modification example. FIG. 6A illustrates a case in which the operation of the first airflow generation device is OFF. FIG. 6B illustrates a case in which the operation of the first airflow generation device is ON.

As illustrated in FIGS. 6A and 6B, an odor presentation module 100-3 includes an odor-containing airflow generation unit 109-3, and a control airflow generation unit 119 that controls an odor-containing airflow generated by the odor-containing airflow generation unit 109-3, as in the first example.

The odor-containing airflow generation unit 109-3 includes the first airflow generation device 101, the flow path 102 having one end at which the first airflow generation device 101 is provided, the odor carrying portion 103 provided in the flow path 102, and the first opening 104 that is the other end of the flow path 102.

Further, the first opening 104 is provided with an opening and closing valve 143 that opens at a specific pressure. As illustrated in FIG. 6A, when the operation of the first airflow generation device 101 is OFF, the opening and closing valve 143 closes the first opening 104 to block the flow path 102, and no airflow flows through the flow path 102. On the other hand, as illustrated in FIG. 6B, when the operation of the first airflow generation device 101 is ON, the opening and closing valve 143 opens and separates from the first opening 104 so that the airflow flows in the flow path 102. Thus, the opening and closing valve 143 blocks the flow path 102 by closing the first opening 104 at the time of stopping of an operation of the first airflow generation device 101.

The first airflow generation device 101, the flow path 102, the odor carrying portion 103, and the first opening 104 included in the odor-containing airflow generation unit 109-3 may be the same as the respective components included in the odor-containing airflow generation unit 109 described in (2) above, and the description thereof also applies to the present example. Further, the respective components included in the control airflow generation unit 119 may be the same as the respective components included in the control airflow generation unit 119 described in (2) above, and the description thereof also applies to the present example.

The odor presentation module 100-3 including the odor-containing airflow generation unit 109-3 closes the opening and closing valve 143 to block the flow path 102 at the time of stopping of the operation of the first airflow generation device 101.

Therefore, in the odor presentation module 100-3, even when there is a gap, for example, between the first airflow generation device 101 and the flow path 102, it is possible to curb generation of airflow in the flow path 102 when the second airflow generation device 111 is operated at the time of stopping of an operation of the first airflow generation device 101. This makes it possible for the odor presentation module 100-3 to curb the emission of the odor from the flow path 102 at an unintended timing or a loss of a fragrance included in the odor carrying portion 103.

Next, an odor presentation module according to another modification example of the present example will be described with reference to FIG. 7. FIG. 7 is a schematic diagram of the odor presentation module of the other modification example.

As illustrated in FIG. 7, the odor presentation module 100-4 includes an odor-containing airflow generation unit 109-4, and a control airflow generation unit 119 that controls an odor-containing airflow generated by the odor-containing airflow generation unit 109-4, as in the first example.

The odor-containing airflow generation unit 109-4 includes the first airflow generation device 101, the flow path 102 having one end at which the first airflow generation device 101 is provided, the odor carrying portion 103 provided in the flow path 102, and the first opening 104 that is the other end of the flow path 102.

Further, a shield 144 is provided in the flow path 102 near the inlet 105 and the outlet 106 of the odor carrying portion 103. The shield 144 narrows the inside of the flow path 102, and shields a flow of airflow generated in the path 102 at the time of stopping of the operation of the first airflow generation device 101, or reduces a flow rate of the airflow. The shield 144 may be provided at any one of the inlet 105 and the outlet 106 of the odor carrying portion 103.

The first airflow generation device 101, the flow path 102, the odor carrying portion 103, and the first opening 104 included in the odor-containing airflow generation unit 109-4 may be the same as the respective components included in the odor-containing airflow generation unit 109 described in (2) above, and the description thereof also applies to the present example. Further, the respective components included in the control airflow generation unit 119 may be the same as the respective components included in the control airflow generation unit 119 described in (2) above, and the description thereof also applies to the present example.

The odor presentation module 100-4 including the odor-containing airflow generation unit 109-4 narrows the inside of the flow path 102 using the shield 144 at the time of stopping of the operation of the first airflow generation device 101, thereby reducing a flow rate of the airflow generated in the path 102 at the time of stopping of the operation of the first airflow generation device 101.

Therefore, in the odor presentation module 100-4, even when there is a gap, for example, between the first airflow generation device 101 and the flow path 102, it is possible to curb generation of airflow in the flow path 102 when the second airflow generation device 111 is operated at the time of stopping of an operation of the first airflow generation device 101. This makes it possible for the odor presentation module 100-4 to curb the emission of the odor from the flow path 102 at an unintended timing or a loss of a fragrance included in the odor carrying portion 103.

(5) Fourth Example of First Embodiment (Example of Odor Presentation Module)

Another example of the odor presentation module according to the present technology will be described with reference to FIG. 8. FIG. 8 is a schematic diagram of the odor presentation module of the other example. FIG. 8A illustrates a case in which the operation of the first airflow generation device is OFF. FIG. 8B illustrates a case in which the operation of the first airflow generation device is ON.

As illustrated in FIGS. 8A and 8B, the odor presentation module 100-5 includes an odor-containing airflow generation unit 109-5, and the control airflow generation unit 119 that controls the odor-containing airflow generated by the odor-containing airflow generation unit 109-5.

The odor-containing airflow generation unit 109-5 includes a first airflow generation device 101, a flow path 152 having one end at which the first airflow generation device 101 is provided, an odor carrying portion 103 provided in the flow path 152, and a first opening 154 that is the other end of the flow path 152. These components form first airflow containing an odor.

The first opening 154 opens to face a direction in which the second airflow B1 blown out from the second airflow generation device 111 flows, inside the flow path 112 of the control airflow generation unit 119. That is, the first opening 154 is provided so that movement of the first airflow exiting the first opening 154 can be controlled by the second airflow B1. The second airflow B1 may be a discharge airflow or may be an intake airflow.

Further, in the flow path 152, a check valve 157 that is an example of an opening and closing valve is provided between the first airflow generation device 101 and the odor carrying portion 103. The check valve 157 is opened when the first airflow flows from the first airflow generation device 101 to the first opening 154 through the flow path 152, and is closed when the airflow flows from the first opening 154 to the first airflow generation device 101 through the flow path 152, to block the flow path 152.

The first airflow generation device 101, the flow path 152, the odor carrying portion 103, and the first opening 154 included in the odor-containing airflow generation unit 109-5 may be the same as the respective components included in the odor-containing airflow generation unit 109 described in (2) above, and the description thereof also applies to the present example. Further, the respective components included in the control airflow generation unit 119 may be the same as the respective components included in the control airflow generation unit 119 described in (2) above, and the description thereof also applies to the present example. In FIGS. 8A and 8B, an upper side of the odor carrying portion 103 is an inlet 155 through which the airflow generated by the first airflow generation device 101 enters the odor carrying portion 103, and a lower side of the odor carrying portion 103 is an outlet 166 through which the airflow passing through the odor carrying portion 103 exits the odor carrying portion 103.

The odor presentation module 100-5 including the odor-containing airflow generation unit 109-5 closes the check valve 157 to block the flow path 152 when the airflow flows back in the flow path 152 from the first opening 154 to the first airflow generation device 101.

Therefore, it is possible for the odor presentation module 100-5 to curb the generation of airflow flowing back through the flow path 152 when there is a gap in the flow path 152 or when the second airflow generation device 111 is operated at the time of stopping of the operation of the first airflow generation device 101. This makes it possible for the odor presentation module 100-5 to curb the emission of an odor from the flow path 152 at an unintended timing or a loss of the fragrance included in the odor carrying portion 103.

(6) Fifth Example of First Embodiment (Example of Odor Presentation Module)

Another example of the odor presentation module according to the present technology will be described with reference to FIG. 9. FIG. 9 is a schematic diagram of the odor presentation module of the other example.

As illustrated in FIG. 9, the odor presentation module 100-5 includes an odor-containing airflow generation unit 109-6, and a control airflow generation unit 119 that controls odor-containing airflow generated by the odor-containing airflow generation unit 109-6.

The odor-containing airflow generation unit 109-6 includes a first airflow generation device 101, a flow path 162 having one end at which the first airflow generation device 101 is provided, an odor carrying portion 163 provided in the flow path 162, and a first opening 164 that is the other end of the flow path 162. These components form the first airflow containing an odors.

The first opening 164 opens in a direction perpendicular to a direction in which the second airflow B1 blown out from the second airflow generation device 111 flows, inside the flow path 112 of the control airflow generation unit 119. That is, the first opening 164 is provided so that movement of the first airflow exiting the first opening 164 can be controlled by the second airflow B1.

The first airflow generation device 101, the flow path 162, the odor carrying portion 163, and the first opening 164 included in the odor-containing airflow generation unit 109-6 may be the same as the respective components included in the odor-containing airflow generation unit 109 described in (2) above, and the description thereof also applies to the present example. Further, the respective components included in the control airflow generation unit 119 may be the same as the respective components included in the control airflow generation unit 119 described in (2) above, and the description thereof also applies to the present example.

Because the odor presentation module 100-6 including the odor-containing airflow generation unit 109-6 is open in the direction perpendicular to the direction in which the second airflow B1 flows, it is possible to curb the generation of airflow in the flow path 162 when there is a gap in the flow path 162, or when the second airflow generation device 111 is operated at the time of stopping of an operation of the first airflow generation device 101. This makes it possible for the odor presentation module 100-6 can curb the emission of an odor from the flow path 162 at an unintended timing or a loss of the fragrance included in the odor carrying portion 163.

According to the odor presentation module 200, it is possible to curb emission of an odor from the flow path 202 at an unintended timing or a loss of a fragrance included in the odor carrying portion 203, similar to the odor presentation module.

Further, as illustrated in FIG. 10, the flow path 202 through which the first airflow A2 flows is provided outside the flow path 212 through which the second airflow B2 flows. Thus, the odor presentation module according to the present technology may include a first flow path through which the first airflow flows, and a second flow path through which the second airflow flows, and the first flow path may be provided outside the second flow path.

The control of the odor as described in (2) above can be performed by the odor presentation module 200 illustrated in FIG. 10. In this case, the first opening 204 and the second opening 213 may be configured such that the first airflow A2 and the second airflow B2 come into contact with each other outside the odor presentation module.

4. Fourth Embodiment (Odor Presentation Method)

The present technology also provides an odor presentation method. The odor presentation method includes a first airflow generation step in which first airflow containing an odor exits the first opening, and a second airflow generation step of generating second airflow exiting the second opening or second airflow entering the second opening, and movement of the first airflow exiting the first opening is controlled by the second airflow.

In the odor presentation method according to the present technology, the movement of the first airflow exiting the first opening is controlled by the second airflow as described above. Therefore, various methods of expressing an odor can be realized.

An order of the first airflow generation step and the second airflow generation step and a time at which these steps are performed may be appropriately set depending on the way the odor is presented. For example, the first airflow generation step may be performed first, and then the second airflow generation step may be performed, or these steps may be performed in the reverse order. Further, the first airflow generation step may be performed at a predetermined timing while the second airflow generation step is continuously performed, or the second airflow generation step may be performed at a predetermined timing while the first airflow generation step is continuously performed.

The method may be performed, for example, by the odor presentation system according to the present technology. Hereinafter, respective steps will be described with reference to FIG. 22.

In the first airflow generation step, the control unit 1402 controls the odor presentation module drive unit 1404 so that the odor presentation module 100-1 and/or 100-2 is driven. The odor presentation module drive unit 1404 drives the first airflow generation devices 101-1 and/or 101-2 of the odor presentation modules 100-1 and/or 100-2. The first airflow generation device 101-1 and/or 101-2 generates airflow, the airflow passes through the odor carrying portions 103-1 and/or 103-2, and the first airflow A1 and/or A2 containing an odor is generated. The first airflows A1 and/or A2 exits the first openings 104-1 and/or 104-2.

Thus, the odor presentation system 1400 exits the first airflows A1 and/or A2 containing an odor from the first openings 104-1 and/or 104-2.

In the second airflow generation step, the control unit 1402 controls the odor presentation module drive unit 1404 so that the odor presentation module 100-1 and/or 100-2 is driven. The odor presentation module drive unit 1404 drives the second airflow generation devices 111-1 and/or 111-2 of the odor presentation modules 100-1 and/or 100-2. The second airflow generation device 111-1 and/or 111-2 generates the second airflows B1 and/or B2. The second airflows B1 and/or B2 exits the second opening 113-1 and/or 113-2.

Thus, the odor presentation system 1400 emits the second airflows B1 and/or B2 containing an odor from the second openings 113-1 and/or 113-2.

The first openings 104-1 and 104-2 are inside the second openings 113-1 and 113-2, respectively. Therefore, movements of the first airflow A1 and A2 are controlled by the second airflow B1 and B2, respectively.

For example, the first airflow A1 is generated while the second airflow B1 is continuously generated, making it possible to express the drifting odor due to the odor component in the first airflow A1.

Further, it is possible to express the local odor by temporarily stopping the generation of the second airflow B1 and generating the first airflow A1 for a short time (for example, injecting the first airflow A1).

Further, it is possible to express the disappearance of the odor by continuously generating the first airflow A1 and stopping the generation of the first airflow A1 and generating the second airflow B1.

The method of expressing the odor is not limited to these. It is possible to realize various expressions of an odor by adjusting the flow velocity, a generation time, a generation start timing, a generation stop timing, and the like of the first airflow A1 and the second airflow B1.

Similarly, various expressions of the first airflow A2 and the second airflow B2 can be realized. Further, various expressions can be realized by various combinations of the first airflow A1 and the second airflow B1 and the first airflow A2 and the second airflow B2.

A more specific example of the odor expression in the odor presentation method in the present technology will be further described hereinafter.

Using the odor presentation method of the present technology, it is possible to present the odor to the user through link to, for example, a video indicating a situation in which an odor drifts softly or an experience in which an odor drifts softly. In this case, the odor presentation system 1400 of the present technology can be controlled as follows, for example.

First, the odor presentation system 1400 continuously generates the second airflows B1 and/or B2 (for example, a slightly weak airflow). Accordingly, the user does not receive wind pressure due to the second airflows B1 and/or B2.

The odor presentation system 1400 emits the first airflows A1 and/or A2 from the first openings 104-1 and/or 104-2 at a timing when the user views the video or receives the experience. Accordingly, the first airflows A1 and/or A2 is mixed with the second airflows B1 and/or B2 and reaches the user. Because a difference in wind pressure before and after the first airflows A1 and/or A2 reaches is small, it is possible to express a softly drifting odor.

Using the odor presentation method of the present technology, it is possible to present the odor to the user through link to a video or experience in which the odor is emitted to the user from a screen on which a video is presented (for example, a video or experience in which a spray can be applied, a video in which a cannon explodes to this side, or a video in which a pistol fires), for example, In this case, the odor presentation system 1400 of the present technology can be controlled as follows, for example.

First, the odor presentation system 1400 maintains its state when the odor presentation system 1400 stops the generation of the second airflows B1 and/or B2 or the generation of the second airflows B1 and/or B2 is not performed. Accordingly, the user does not receive the wind pressure due to the second airflows B1 and/or B2. At a timing when the user views the video or receives the experience, the odor presentation system 1400 emits the first airflows A1 and/or A2 from the first openings 104-1 and/or 104-2 (for example, the first airflows A1 and/or A2 are injected from the first openings 104-1 and/or 104-2). Accordingly, only the first airflows A1 and/or A2 reaches the user. Because a wind pressure difference before and after the first airflows A1 and/or A2 reaches is large, it is possible to express a suddenly generated odor.

Using the odor presentation method of the present technology, it is possible to express disappearance of the odor through link to a video or experience in which an odor on a screen on which a video is presented disappears (for example, a video or experience in which smoke disappears, or a video or experience in which a food generating an odor is sealed), for example. In this case, the odor presentation system 1400 of the present technology can be controlled as follows, for example.

The odor presentation system 1400 generates the first airflows A1 and/or A2. Accordingly, the user perceives the odor. The second airflows B1 and/or B2 may not be generated or may be generated while the first airflows A1 and/or A2 are generated. Then, the odor presentation system 1400 stops the generation of the first airflows A1 and/or A2. According to the stop timing, the odor presentation system 1400 starts the generation of the second airflows B1 and/or B2 when the second airflows B1 and/or B2 is not generated, or increases an air volume of the second airflows B1 and/or B2 when the second airflows B1 and/or B2 is generated. This makes it possible for the user not to perceive the odor component contained in the first airflows A1 and/or A2, that is, express the disappearance of the odor.

Further, the odor presentation system 1400 may reverse directions of the second airflows B1 and/or B2 from the outside of each odor presentation module to each second airflow generation device according to the stop timing. That is, the odor presentation system 1400 may start intake using the second airflow generation device. This makes it possible for the user not to perceive the odor component contained in the first airflows A1 and/or A2, that is, express the disappearance of the odor.

The intake enables recovery and/or discharge of the odor component remaining in the odor presentation module or the odor component leaking from the first opening, and contributes to preventing an unnecessary odor from reaching the user.

The way the odor is expressed in the odor presentation method of the present technology is not limited to the above examples.

For example, the odor presentation system 1400 causes the second airflows B1 and/or B2 to be generated, and stops the generation of the second airflows B1 and/or B2 at the same time as start of the generation of the first airflows A1 and/or A2 (particularly, generation during a short time and, more specifically, injection). Then, the odor presentation system 1400 stops the generation of the first airflows A1 and/or A2 and restarts the generation of the second airflows B1 and/or B2. This makes it possible to express, for example, a temporary odor generation (for example, a temporary odor generation).

Further, the odor presentation system 1400 can adjust the flow velocities of the first airflows A1 and A2 and the second airflows B1 and B2. For this adjustment, the control unit 1402 of the odor presentation system 1400 controls the odor presentation module drive unit 1404 to adjust the flow velocity of the airflow generated by the first airflow generation devices 101-1 and 101-2 and the second airflow generation devices 111-1 and 111-2. This makes it possible to change, for example, the intensity of the odor caused by the first airflow A1 and A2, a mixing ratio of the first airflow A1 and A2, a mixing ratio of the first airflow A1 and the second airflow B1, a mixing ratio of the first airflow A2 and the second airflow B2, wind pressure felt by the user, and the like.
