Description

  The present invention relates to an odor spatial distribution control method, an odor spatial distribution control device, an audio-visual system, and a customer guidance system, and causes an air flow having an odor to collide with another air flow to change the direction toward the user. A spatial distribution of odors is formed such that an odor source is present at the location where the flow collides, and the spatial distribution of the odors is variously controlled by controlling these air flows.

  Conventionally, in the field of movies and virtual reality, attempts have been made to improve the sense of reality by smell. Specifically, Sensolama (Patent Document 1) developed in the early 1960s blows air in a scene where a motorcycle runs, and provides the audience with the smell of pizza in a scene where the motorcycle passes in front of an Italian restaurant.

  In recent years, an apparatus has been developed that sets several kinds of fragrances and selects fragrances according to the scene from the fragrances to provide odors. Incidentally, such a device is called an olfactory display.

  Specifically, Non-Patent Document 1 proposes a method of supplying an odor through a tube arranged in the vicinity of the nose, applied to a game device. Non-Patent Document 2 proposes a method in which a so-called air gun vortex ring is fired toward the user's face and odor is provided through the vortex ring.

  However, conventional devices still have insufficient problems in practical use.

  That is, for example, it is assumed that a teapot containing peach tea and an empty teapot are arranged side by side on a table. In this case, in the real world, if you bring your face close to a teapot containing peach tea, you will feel the smell of peach. Therefore, when such two teapot images are displayed and smell is provided by an olfactory display, the user can feel the smell of peach when the user brings his face close to the image of the teapot containing peach tea. Is required.

  When reproducing such a situation with the olfactory display described in Non-Patent Document 1, it is possible to detect that the face has been brought close to the image of the teapot containing peach tea by some method, and to provide the smell of peach from the tube I need it. Therefore, in the olfactory display described in Non-Patent Document 1, it is necessary to provide a face detection mechanism, and there is a problem that the configuration is complicated.

  Further, when reproducing such a situation by the olfactory display described in Non-Patent Document 2, similarly, it is detected that the face is brought close to the image of the teapot containing peach tea, and a vortex ring is launched aiming at the face. It will be. It is extremely difficult to reliably hit the whirlpools on the faces of users who move around here. Therefore, in this case, the configuration becomes complicated, and it is impossible to provide an odor more reliably.

  The present invention has been made in view of the above-described problems, and a method for controlling the spatial distribution of odors and an odor spatial distribution control apparatus capable of variously controlling the spatial distribution of odors relating to the odor source in a simple and reliable manner. It is to provide an audiovisual system and a customer guidance system. That is, this invention is comprised from the following technical matters.

  Hereinafter, embodiments of the present invention will be described.

(1) 1st Embodiment FIG. 1: is a figure which shows the spatial distribution control apparatus of the odor used for the experiment of this invention. The odor spatial distribution control device 1 is provided with, for example, an image display device 2 using a liquid crystal display device. The odor spatial distribution control device 1 is provided with blowers 3L and 3R facing each other on both sides and the front side of the display screen of the image display device 2, and sends out an odorous air flow from both of the blowers 3L and 3R. To do. The odor spatial distribution control device 1 causes the air flow having this odor to collide with the air flow from the other blower to change the flow to the user side, so that the location where the air flow collides is the odor source. Form a spatial distribution of odors. Further, the odor spatial distribution control device 1 controls the air flow to change various locations where the air flow collides, thereby variously controlling the odor spatial distribution related to the odor source. When practically sufficient characteristics can be secured, instead of sending an air flow having an odor from both of the fans 3L and 3R, an air flow having an odor is sent only from one side of the fans 3L and 3R. It may be made to collide with the air flow without an odor sent from the other blower.

  In other words, in the odor spatial distribution control device 1, the blowers 3L and 3R are fans whose rotation speeds can be varied, and are arranged on struts that can be expanded and contracted. The fans 3L and 3R are provided with a sensor for detecting the rotation speed, and the rotation speed is controlled by feedback control using an output signal of the sensor. In this embodiment, the same fan is applied to the fans 3L and 3R.

  Here, the airflows sent out from the two blowers 3L and 3R collide between the blowers 3L and 3R and change their directions. In FIG. 1, this change in direction is indicated by an arrow. Therefore, in this odor spatial distribution control device 1, the wind blows from the display screen side of the image display device 2 toward the user's face, and the illusion that the wind is blowing from the displayed image. Can be given. As a result, the odor spatial distribution control device 1 creates a wind blown from the screen with a simple configuration without providing a special configuration.

  Here, if the air volume sent from the blowers 3L and 3R is varied while the ratio of the air volumes sent from the left and right blowers 3L and 3R is maintained at a constant value, the strength of the wind blown toward the user's face can be varied. Can do. In addition, when the air volume is extremely reduced, it is possible to prevent the perception of wind blowing.

  On the other hand, when the air volume sent from the left and right blowers 3L and 3R is changed in a complementary manner, the location where the air flow sent from the blowers 3L and 3R collides changes from the central location between the blowers 3L and 3R to the left and right respectively. Can be made. Therefore, in this case, it is possible to move the wind blowing position that seems to blow out from the screen to the left and right of the screen. Therefore, if an odor is mixed in this air flow, the position of the odor source can be changed variously to create a spatial distribution of the odor.

  Therefore, the odor spatial distribution control device 1 is configured such that the tubes 5L and 5R for guiding the odor vapor are connected to the fans 3L and 3R, respectively, so that the odor vapor can be mixed into the air flow sent from the fans 3L and 3R. Here, the odor vapor is a vapor containing odor.

  The position of such an odor source can be changed by changing the ratio of the air volume sent from the two blowers 3L and 3R. Therefore, instead of changing the air volume in a complementary manner, even if the air volume of the other blower is changed while keeping the air volume of one blower at a constant value, the location where the air flow collides can be changed similarly. . However, in this case, the strength of the wind blowing toward the face changes.

  However, when the air flows from the left and right blowers 3L and 3R are simply collided, the air flow is directed not only on the user side but also in the vertical direction. This upward and downward air flow is useless for controlling the spatial distribution of odors. Therefore, in the odor spatial distribution control device 1, the efficiency is reduced by the amount of the vertical air flow. In addition, an unexpected trouble such as an odor being perceived at an unexpected location due to the vertical air flow is also predicted. Therefore, in the odor spatial distribution control device 1, an air flow shaping mechanism is provided in the blowers 3L and 3R. The odor spatial distribution control device 1 uses the air flow shaping mechanism to change the cross-sectional shape of the air flow sent from the blowers 3L and 3R to a flat shape with a narrow direction in which the user is positioned, thereby Reduce the wasteful air flow that heads.

  More specifically, in this embodiment, rectifying covers 4L and 4R using ducts are provided at the outlets of the fans 3L and 3R as the air flow rectifying mechanism. Here, the rectifying covers 4L and 4R are ducts whose cross-sectional shape is a vertically long rectangular shape. Note that a shaping mechanism using a duct having an elliptical cross section or the like may be configured instead of the shaping mechanism using a duct having a rectangular cross section. Moreover, instead of or in addition to the shaping mechanism using such a duct, by arranging small fans closely in the vertical direction, the cross-sectional shape of the air flow is made flat with a narrow direction in which the user is positioned. In addition, various configurations can be widely applied to the air flow shaping mechanism.

2 and 3 are diagrams showing measurement results when the air volume of the air flow from the fans 3L and 3R is changed in a complementary manner in the odor spatial distribution control device 1. FIG. The blowers 3L and 3R have a maximum rotational speed of 4600 [rpm], and the air volume at the maximum rotational speed is 0.65 [m ³ / min]. Therefore, for example, when driven at a rotational speed of 3700 [rpm], the air volume is estimated to be approximately 0.65 × 3700/4600 [m ³ / min].

  FIG. 2A shows a case where the left and right blowers 3L and 3R are driven at the same rotational speed of 3700 [rpm]. In this case, it was perceived that the wind was blowing from almost the center of the display screen. FIG. 2B shows the case where the left and right blowers 3L and 3R are set to 3200 [rpm] and 4200 [rpm], respectively. In this case, the wind blows from the position displaced from the center of the screen to the left side. Was perceived as. FIG. 2C shows the case where the left and right blowers 3L and 3R are set to 4200 [rpm] and 3200 [rpm], respectively. In this case, the wind blows from the position displaced from the center of the screen to the right side. Was perceived as.

  FIG. 3 shows the air volume from the screen with reference to the center of the screen on a straight line 18 cm away from the straight line connecting the fans 3L and 3R to the user side in the case of FIGS. Is measured. In FIG. 3, the symbols LC, LL, and LR are measurement results according to the settings of FIGS. 2A, 2 </ b> B, and 2 </ b> C, respectively. According to FIG. 3, it can be seen that the wind blowing position can be varied to the left and right of the screen by varying the air volume of the fans 3L and 3R.

  FIG. 4 is a diagram for explaining an odor perception experiment. As shown in FIG. 4 (A), the three teapots PL, PC, PR are actually arranged side by side on the table, the leftmost teapot PL contains peach tea, and the remaining two teapots PC, Assume that PR is empty. In this case, when the wind blows from behind the teapots PL, PC, PR, the smell of peach from the left teapot PL is carried to the user by the wind and perceived by the user. Therefore, a space having a smell of peach scent is formed in the lee of the left teapot PL, and the user can feel the scent of peach only in the lee of the left teapot PL. If the wind is not blowing, as shown by the arrows, peach tea enters the leftmost teapot PL by smelling the three teapots PL, PC, PR by approaching their faces in order. Can be confirmed.

  As shown in FIG. 4 (B), an image of the three teapots PL, PC, and PR shown in FIG. 4 (A) is displayed on the image display device 2, and an experiment in which the user smells from which pot is smelled. Went. The odorous vapor was generated by bubbling a commercially available peach fragrance and supplied to the left and right blowers 3L and 3R in an equal amount (200 [ml / min]). In this case, the space to which the air flow from the left and right blowers 3L and 3R is supplied becomes a space having a peach odor, and if it is limited to the front of the display screen, the odor distribution is almost the same as the actual odor distribution. Space can be provided.

  In this state, if the left and right blowers 3L and 3R are set to 1300 [rpm] or less, the user can hardly perceive the wind from the screen. Therefore, in the arrangement of the actual teapots PL, PC, and PR described above with reference to FIG. In the experiment, when the odor distribution was brought to the position of the left teapot PL, the rotation speeds of the left and right blowers 3L and 3R were set to 1100 [rpm] and 1800 [rpm]. When the odor distribution was brought to the position of the right teapot PR, the reverse was made. Further, when the odor distribution was brought to the position of the center teapot PC, the rotational speeds of the left and right fans were set to 1300 [rpm].

  In this state, as indicated by an arrow, when the face was brought close to the screen and it was confirmed from which teapot image the scent was found, the teapot at the generally intended location could be found. In the actual measurement using a gas sensor, the odor space with almost the same odor distribution as the actual one was confirmed.

  Thereby, in this odor spatial distribution control device 1, when a face is brought close to the image of the teapot, it is possible to reproduce the situation where the smell of peach tea is scented. Also, by increasing the air volume (by setting the rotational speed of the blowers 3L and 3R to 3700 [rpm] or more), it is possible to make the user feel the wind while delivering the smell, in this case, the direction in which the wind is blowing It is possible to make the user perceive that the smell came from. Therefore, for example, an image of a flower bed of roses can be displayed, and a situation in which the smell of roses drifts from the flower bed by this image can be formed.

  FIG. 5 is a diagram showing measurement results used for confirming the effects of the rectifying covers 4L and 4R. Reference numeral LH indicates the amount of air flow in the horizontal direction due to the collision of the air flow from the two blowers 3L and 3R. In addition, the flow rate in the horizontal direction when the rectifying covers 4L and 4R are rotated by 90 degrees by the symbol LV is shown. According to the measurement result of FIG. 5, it can be seen that the odor air flow can be sent to the user side sufficiently efficiently.

  According to the above configuration, the air flow having an odor is made to collide with another air flow and turn to the user side, and by controlling the air flow, the location where the air flow collides can be easily changed. In addition, it is possible to reliably form a spatial distribution of odors such that the location where the air flow collides is an odor source, and variously control the spatial distribution of the odors.

  In other words, the odor is easily and reliably changed by colliding the air flow generated by the two blowers, changing the direction of the odorous air flow toward the user, and changing the location where the air flow collides by controlling the blower. It is possible to control the spatial distribution of odors related to various sources.

  In addition, by providing a shaping mechanism and making the cross-sectional shape of the air flow sent out from the blower a flat shape with a narrow direction in which the user is located, the spatial distribution of the odor related to the odor source can be controlled in various ways efficiently. Can do. Moreover, unexpected troubles can be reduced.

  More specifically, since this shaping mechanism is a duct arranged at the air flow outlet, the efficiency is improved by a simple configuration, and the odor is perceived at an unexpected location. Trouble can be reduced.

  More specifically, since the control of the blower is the control of the air volume of the air flow, various spatial distributions of odors can be controlled with simple control.

(2) Second Embodiment FIG. 6 is a diagram showing an odor spatial distribution control device according to a second embodiment of the present invention, in comparison with FIG. In this odor spatial distribution control device 11, the same configuration as that of the odor spatial distribution control device 1 described above with reference to FIG. 1 is denoted by the corresponding reference numeral, and redundant description is omitted.

  As shown by an arrow A, the odor space distribution control device 11 is configured such that the blowers 3L and 3R are rotatably supported on a support column, and thereby the direction of air flow from the blowers 3L and 3R can be variably controlled. Configured. Note that the control of the delivery direction may be executed by changing the orientation of the delivery port instead of or in addition to changing the orientation of the blower, and various methods can be widely applied.

  As shown in FIG. 7, the odor spatial distribution control device 11 is configured so that the location where the two air flows collide with each other is located on the user side with respect to the straight line connecting the two blowers 3L and 3R. The direction of the blowers 3L and 3R is controlled. As a result, the odor spatial distribution control device 11 reduces the air flow R toward the display screen and efficiently sends the air flow F to the user side.

  In other words, by providing the rectifying covers 4L and 4R, the air flow going up and down increases the efficiency by reducing the flow rate, and further reduces troubles such as odors being perceived in unexpected places. Can do. However, even if the rectifying covers 4L and 4R are provided, in the odor spatial distribution control device 1, an air flow substantially equal to the air flow toward the user side is directed to the display screen side. Therefore, the efficiency decreases due to the air flow toward the display screen, and an unexpected trouble is predicted.

  However, as in this embodiment, if the location where the two air flows collide is set to a position that is biased toward the user side from the straight line connecting the two blowers 3L, 3R, the air flow toward the display screen side R can be remarkably reduced. Therefore, the efficiency can be further improved, and troubles such as odors being perceived in unexpected places can be significantly reduced.

  As a result, the odor spatial distribution control device 11 controls the air volume of the fans 3L and 3R and changes the direction of the fans 3L and 3R so as to correspond to the control of the air volume. That is, as shown in FIG. 7, when the air volume of the left blower 3L is relatively increased so that the odor source is present on the right side of the display screen, it corresponds to the air volumes of the blowers 3L and 3R. In addition, the direction of the right blower 3R is greatly inclined (α <β) as compared with the left blower 3L, thereby the two blowers 3L at the user side corresponding to the position of the odor source set by the air volume. Set so that the airflow from 3R collides.

  Note that on the premise of controlling the air volume of the fans 3L and 3R in this way, instead of changing the direction of the fans 3L and 3R so as to correspond to the control of the air volume, the air volume of the air flow sent from the fans 3L and 3R is constant. The position of the odor source may be set only by controlling the direction of the air flow sent from the blowers 3L and 3R so as to hold the value. In controlling the direction of the air flow, both directions may be changed, or only one direction may be changed.

  FIG. 8 is a diagram showing the measurement results of the air flow when the direction of the air blowers 3L and 3R is changed so as to correspond to the control of the air flow on the premise of the control of the air flow of the blowers 3L and 3R. Reference numerals FL and RL are measurement results of the air flow toward the user side and the display screen side when the odor source is set on the left side of the display screen, respectively. Symbols FR and RR are measurement results of the air flow toward the user side and the display screen side when the odor source is set on the right side of the display screen, respectively. According to FIG. 8, it can be seen that the collided air flow is efficiently sent to the user side.

  According to this embodiment, by controlling the delivery direction of the two air flows, the efficiency is further improved, and furthermore, troubles such as odors being perceived in unexpected places are significantly reduced. Can do.

(3) Third Embodiment FIG. 9 is a diagram showing an audiovisual system according to a third embodiment of the present invention. In this audiovisual system 21, the same configuration as that of the odor spatial distribution control device 1 or 11 described above with reference to FIGS. 1 and 6 is denoted by the corresponding reference numeral, and redundant description is omitted. The audiovisual system 21 provides users with video content such as movies and music videos, and audio content such as popular music and classical music. Therefore, the audiovisual system 21 accumulates and holds these video content and audio content in the server 22. In addition, a playback device 28, an image display device 2, and speakers 23R and 23L for playback of the video content and audio content are provided.

  The audiovisual system 21 is provided with an odor space distribution control device 25 similar to the odor space distribution control devices 1 and 11 described above, and forms an odor space in synchronization with video content and audio content provided to the user. The odor spatial distribution control device 25 is configured in the same manner as the odor spatial distribution control device 1 or 11 except for the configuration relating to the control of each unit described in detail below.

  More specifically, the audiovisual system 21 forms an odor space for video content in synchronization with each scene of the video content. That is, for example, in the battle scene, the smell of gunpowder is provided to the user, and in the scene on the beach, the smell of the sea is provided to the user. Furthermore, in the dining table scene, the user is provided with a corresponding scent of food. On the other hand, the audiovisual system 21 forms an odor space corresponding to the image of each piece of music in synchronism with each piece of music. That is, for example, jazz, blues, etc. provide the user with the smell of cigarettes as if they were watching live performances in a live house. For this reason, the video content and the audio content are stored in the server 22 with various control data necessary for the control of the odor spatial distribution control device 25 added thereto.

  Here, in the video content, the control data may be recorded in the server 22 in a separate file format in which a link with the video content file is set, for example, and further recorded in a file format integrated with the video content. You may do it. By the way, in the case of this integrated file format, for example, the QT file format is applied, and the control track by the control data is formed in the movie data atom similarly to the video track and the audio track, and these tracks are synchronized and reproduced. It is possible to do. On the other hand, with respect to audio data, control data can be recorded for each piece of music using the metadata of each piece of music. In the audio content, various data indicating the characteristics of each music piece may be used instead of the control data. Incidentally, a category code indicating the category of each music such as country, blues, and waltz can be applied to such data.

  The playback device 28 plays back the content held in the server 22 and drives the image display device 2 and the speakers 23L and 23R according to a user instruction via a remote commander (not shown). At this time, the playback device 28 outputs control data obtained by sequentially playing back video content and audio content from the server 22 to the controller 26.

  The controller 26 is a control unit that controls the odor spatial distribution control device 25. The controller 26 controls the odor generating source 27 and the fans 3L and 3R according to the control data output from the playback device 28 when the user instructs the generation of the odor space synchronized with the content. Here, the odor generation source 27 is a device that generates various odor vapors under the control of the controller 26, and in this embodiment, a plurality of odor sources used to generate the odor vapor are provided. Specifically, the odor source is, for example, a scent of explosives, a scent of sea, a scent of various dishes, a cigarette scent, and the like. The odor generating source 27 selectively bubbles these odor sources under the control of the controller 26 to generate odor vapor. At this time, the bubbling intensity is varied, and the odor intensity is varied.

  That is, in this case, the controller 26 controls the odor generating source 27 in accordance with the control data to generate odor vapor of the type and concentration corresponding to each scene, mix this odor vapor into the air flow, and send it out from the blowers 3L, 3R. To do. Thus, an odor source is formed on the display screen according to the control data, and an odor space corresponding to each scene is created. At this time, the air volume of the blowers 3L and 3R is set according to the control data so that the user can perceive the wind by the desired air volume, and further, the user is set not to perceive this wind.

  In addition, depending on the scene, the controller 26 controls the stop of generation of odorous vapor based on the control data and drives only the fans 3L and 3R, thereby providing only the wind to the user with the intensity corresponding to each scene.

  On the other hand, when the scene is changed from the state in which the scent is provided to the user, the controller 26 stops the generation of the odorous vapor based on the control data, and the blower 3L, 3R is driven. As a result, the odor spatial distribution control device 25 prevents the odor from being included in the air flow sent out from the blowers 3L and 3R, and makes it difficult to perceive the stagnation odor quickly. Furthermore, in the case of providing different odors in successive scenes, the air flow stays in the same way for a certain period before the scene changes and / or for a certain period after the scenes change. This eliminates the unpleasant situation caused by the mixing of different odors.

  On the other hand, when reproducing audio content, various odor spaces are similarly formed according to the recording of the server. In this case, instead of creating an odor space synchronized with audio content, an odor space instructed by the user may be created.

  According to the above configuration, by applying to the audiovisual system and controlling the blower in synchronization with the video content or the audio content, it is possible to create an odor space corresponding to each content and further improve the sense of reality. be able to.

  At this time, by preventing the odor from being included in the air flow sent out from the blower, it is possible to make the user feel a scentless wind and to construct a more realistic audiovisual system. In addition, stagnant smell can be prevented and user discomfort can be prevented.

(4) Fourth Embodiment In the fourth embodiment, an odor space is created in synchronism with video content displayed on a screen by applying to a so-called amusement park audio-visual system. For this reason, in this embodiment, a blower is provided for each user, and the blowers of each user are controlled simultaneously in parallel. This embodiment has the same configuration as that of the third embodiment except that the configuration related to the blower is different.

  In addition, in installing the blower for each user, for example, it may be provided in a front row seat. In this case, however, it is necessary for the users in the front row not to perceive the odor space by the blower arranged in the seat, and as a result, as described above with respect to the second embodiment, the two blowers are used. The blower is arranged so that the delivery direction is movable toward the rear seat side so that the two air flows collide on the user side from the connecting straight line.

  Moreover, when arrange | positioning an air blower in a front seat in this way, generally an air blower will be arrange | positioned below the direction of a screen. Therefore, in this case, the sending direction is set so that each air blower sends the air flow obliquely upward by the amount arranged below the direction of the screen, and the sending direction is set to be movable. .

  According to this embodiment, by providing a blower for each seat, it is applied to an audiovisual system in which a large number of users view one video content or the like simultaneously, such as an audiovisual system for an amusement park. The same effect as the embodiment can be obtained.

(5) Fifth Embodiment In this embodiment, the odor spatial distribution control devices 1 and 11 are installed in various sales floors, and a customer is guided by the odor. That is, for example, it has been reported that sales of potatoes and carrots increased when the smell of curry was flown at a supermarket vegetable store. However, if a device that simply generates an odor is arranged, the user may notice the device related to the odor. In this case, the impression is worsened. However, the odor space distribution control devices 1 and 11 can form an odor space in which the collision point of the air flow is the source of the odor, thereby creating an odor space in which the odor drifts from an empty space. Can be created. As a result, customers can be guided much more than in the past. In this way, the odor spatial distribution control device applied to this embodiment has a configuration in which the image display device is omitted.

  Alternatively, for example, in front of a store such as a restaurant, a fan may be arranged facing the road to form an odor space, thereby guiding the customer. In this case, it is conceivable that the air flow colliding with a passerby traveling on the road is set so as to be moved and gradually moved so that the colliding part approaches the entrance of the store. Further, when there is a large amount of traffic, the location where the air flow collides may be moved in the opposite direction to make many passers-by notice the presence of the store.

  In this embodiment, the range of application of this type of device can be further expanded by guiding customers by the scent of the scent spatial distribution control device described above.
