Description

  The present invention belongs to the technical field of a scented video presentation device capable of efficiently receiving a scent by inducing inspiration by video and air tactile senses, and a content production method for producing content reproduced by the scented video presentation device. .

  In recent years, video display devices have been developed with large screens and thinner technologies, and there are less restrictions on installation locations, and can be used by being hung on a wall or embedded in a wall. If this technology is used as an electronic signage (digital signage) on the wall of a passage in an underground shopping street, it is much more flexible than a signboard using conventional photographs. However, digital signage is expensive and needs to be cost effective. In other words, there are problems such as improving the attractiveness, making the pedestrian stop, and developing the content linked to sales promotion after the stop. The present inventor is conducting research to increase the added value of digital signage by combining fragrance and video.

  In sales promotion advertisements using scented images, the development of technology that appropriately presents scents related to product images from non-wearing and distant places has become an issue. In the conventional scent presentation method, a method is generally used in which a fragrance is vaporized and placed in an air current to continuously release the scent in the vicinity of the nostril for a predetermined time. However, if a large amount of perfume chemicals is released into the air, olfactory presentation is easy, but the chemicals diffuse to the surroundings, and there is a problem that the scent stays forever. It is difficult to switch scents according to the switching of video content, and if there is psychological resistance to scents, the scented space is unpleasant.

  In order to improve this problem, Patent Document 1 discloses a method of mixing a fragrance in a continuous air flow in a pulsed manner in consideration of the intake timing. Compared to the method of releasing scent continuously, efficient presentation of olfaction is possible with a small amount of fragrance, but the inspiration timing varies among individuals, and there remains a problem that a scent deviating from the inspiration timing is not accepted.

  Patent Document 2 discloses a technique for generating an air vortex ring mixed with a scent by an air cannon and releasing it to a human nose. Compared with the method of using a continuous air flow as the scent conveying means, there is a feature that the scent can be presented pinpoint spatially and temporally. However, a control technique for conveying the vortex ring near the nostrils in accordance with the intake air becomes a problem.

  As a method for solving this problem, the present inventor, in Patent Document 3 or Patent Document 4, detects inspiration timing using a sensor, or detects expiration using a sensor, and determines inspiration timing from expiration. A method for estimating and releasing a perfume chemical substance at the timing is disclosed. However, since it is difficult to detect exhaled air and inhaled air by a non-contact means, there is a problem that the system configuration is complicated.

  Therefore, as a method for presenting a scent to the nose at the timing of inspiration without using a sensor, a method for inducing inspiration was examined. In the video content, we also considered a method of notifying the intake timing by counting down with numbers and bars. FIG. 9 is a diagram for explaining an inhalation-guided scent presentation method using a conventional timing bar. The user feels the scent presentation timing based on how the timing bar is reduced and performs a conscious intake operation. However, the method of requesting the user to inhale has a problem that the feeling of immersion in the video is impaired.

  Therefore, the present invention naturally realizes olfactory presentation with a small amount of fragrance by naturally inducing a person's inspiration without giving a sense of instruction and releasing the scent to the nose at a time when inhalation is likely to occur. In addition, the present invention provides a scented video presentation device that realizes a sense of presence as if it is scented from the target video presented on the screen, and a content production method for producing content that is played back by the scented video presentation device. Is an issue.

Note that the air tactile sense presenting means and the scent presenting means may be configured integrally. Further, in the scene where the scent of the content is presented, the scent presentation means may be combined with other than the above means. That is, a scent presentation means that does not involve an air tactile sense presentation means may be used in combination.

  According to a second aspect of the present invention, the air tactile sensation presenting means generates an air flow that accelerates a change in speed per second in a range of 50 cm to 5 m / second to the person and causes skin irritation. It exists in the image presentation apparatus with a fragrance of Claim 1 characterized by the above-mentioned.

  According to a third aspect of the present invention, the scent information includes only air tactile information indicating a timing at which an air tactile sensation is presented, and the air tactile sense presenting means generates the air flow at the timing indicated in the air tactile information. The scented image according to claim 1 or 2, wherein the scent presenting means presents the scent after a predetermined time has elapsed since the scent presenting means presented the air haptic sense by the air tactile sense presenting means. It exists in the presentation device.

  The invention according to claim 4 is characterized in that the scent information includes air tactile information indicating a timing for presenting an air tactile sense and scent presentation information indicating a timing for presenting a scent, and the air tactile sense presenting means includes the air The air flow is generated at the timing indicated by the tactile information to present an air tactile sense, and the scent presenting means generates the scented air flow at the timing indicated by the scent presentation information to present the scent. It exists in the image presentation apparatus with a fragrance of Claim 1 or 2 to do.

  According to a fifth aspect of the present invention, the scent presenting means generates the scented air flow within 1/2 or 2 seconds of a person's breathing interval after the air tactile sense is presented by the air tactile sense presenting means. The scented video presentation device according to any one of claims 1 to 4, wherein the scented video presentation device is provided.

And the scent presenting means presents the generated airflow through the plurality of holes provided in the display screen.

  The invention according to claim 7 further includes person approach detecting means for detecting approach of a person, and the reproducing means automatically reproduces the content when the approach of the person is detected by the person approach detecting means. It exists in the image presentation apparatus with a fragrance in any one of Claims 1-6 characterized by these.

  The invention according to claim 8 is characterized in that the air tactile sensation presentation means and the scent presentation means have a blade mechanism for controlling the flow direction of the airflow. It exists in the video presentation device.

  Invention of Claim 9 is a content production method which produces the content reproduced | regenerated with the scented video presentation apparatus of Claims 1-8, Comprising: During reproduction | regeneration of any one of the said video information and the said sound information Generating the scented airflow after the air tactile sensation is presented to the subject, and adding the scent information when the subject's sympathetic mirror neuron measured at that time is activated Lies in the way.

  Invention of Claim 10 is a content production method which produces the content reproduced | regenerated with the scented video presentation apparatus of Claims 1-8, Comprising: During reproduction | regeneration of any one of the said video information and the said sound information In the content production method, the scented airflow is generated after presentation of the air tactile sensation, and the scent information is added when the subject's sympathetic intake action is learned.

  As described above, according to the first, third, and fourth aspects of the present invention, the air tactile sensation presenting means generates an air flow without scent and presents the air tactile sensation to induce a person to inhale, for a predetermined time. The scent presenting means can generate the scented airflow at the timing when the air is inhaled later. For this reason, since the scent is released so that the scent is present in the vicinity of the nasal cavity at the inhalation timing of the person, the scent presentation can be reliably realized with a small amount of fragrance. Since the fragrance to be used is not so much, the fragrance is less likely to diffuse and remain long and the fragrance is rarely presented to persons other than the target person. In addition, when the scent is switched, there is little residual scent, so there is little mixing with the previous scent and a clear scent can be presented.

  In addition, when the speed change per second is 50 cm / second or less, the probability that a skin touch is perceived decreases, and conscious inspiration (sniffing) is unlikely to occur. On the other hand, when it exceeds 5 m / sec, the impact is too great, and thus the defense mechanism of the living body works, and the probability of suppressing conscious expiration is increased. In consideration of the above, according to the second aspect of the present invention, the air tactile sensation presenting means accelerates the speed change per second in the range of 50 cm to 5 m / second with respect to the person and causes skin irritation. Since a squeezing airflow is generated, it is possible to reliably induce human inspiration.

  According to the fifth aspect of the present invention, when an air tactile sensation is presented, inhalation is induced, so that a sniffing operation is likely to occur. Since this operation is frequently performed within 1/2 or 2 seconds of the human breathing interval after presenting the air tactile sense, the scent acceptance can be enhanced by setting in this way.

  According to the sixth aspect of the present invention, it is possible to present an olfactory sense as if it is scented from the image displayed on the screen. Thereby, since an image | video, an air tactile sense, and a fragrance can be shown integrally like a real phenomenon, a highly realistic feeling is realizable. When applied to a bodily sensation game, it becomes a powerful game. When applied to digital signage, the attractiveness to the advertising billboard is improved and the drop-in rate is improved, which is effective for sales promotion.

  According to the seventh aspect of the present invention, content can be automatically reproduced when a person approaches.

  According to the eighth aspect of the invention, by using the blade mechanism, it is possible to present an olfactory sense as if it is smelling from the image displayed on the screen.

  Activation of sympathetic mirror neurons is performed by attaching an electrode that measures hemoglobin in the brain in the vicinity of the motor motility cortex (broker area) or the prefrontal cortex of the brain, and measures the rising speed and acceleration of oxygenated hemoglobin. Alternatively, the rising speed and acceleration of deoxygenated hemoglobin are measured, and the determination can be made when the difference from the normal measurement value exceeds a predetermined value. In addition, the activation of the sympathetic mirror neuron can be measured using an electroencephalogram or a function MRI (magnetic resonance measuring apparatus). As described above, it is possible to distinguish the sympathetic intake operation from the normal intake operation. Therefore, according to the ninth aspect of the invention, at the time of content production, the subject can appreciate it in advance, and scent information can be added to the scene where the subject's sympathetic mirror neurons are activated. Since the scent emitted by the scented presentation device is received in a timely manner, the olfactory presentation can be performed with a small amount of fragrance. In addition, when switching scents, since there is little scent remaining due to the previous scent presentation, high-speed switching is possible. Produced content is easy to accept socially because unnecessary fragrances are rarely scattered around.

  According to the tenth aspect of the present invention, at the time of content production, the subject can appreciate the scent information in advance and the scent information can be added to the scene in which the subject's sympathetic inspiration action is learned. Since the scent emitted by the presentation device is received in a timely manner, olfaction can be presented with a small amount of fragrance. In addition, when switching scents, since there is little scent remaining due to the previous scent presentation, high-speed switching is possible. Produced content is easy to accept socially because unnecessary fragrances are rarely scattered around.

First Embodiment Hereinafter, a scented video presentation apparatus according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a diagram illustrating a configuration of a scented video presentation device and an olfactory presentation method according to the first embodiment of the present invention. As shown in FIG. 1A, the scented video presentation device 1 includes an air tactile sensation presentation device 4 as an air haptic presentation unit, a scent presentation device 5 as a scent presentation unit, and a reproduction device as a reproduction unit (not shown). And a display device 2 as a display means having a screen 6 and a person approach detection means 3. The air tactile sensation presentation device 4 releases (generates) a vortex ring (airflow) of unscented air using the principle of an air cannon and presents the air tactile sensation A1 on the face or head of the person P. . The scent presentation device 5 presents the scent to the person P by discharging the scented airflow A2 toward the vicinity of the olfactory sensation of the person P using the principle of an air cannon. Here, the “scented air vortex ring” means a vortex ring of air released without being supplied with fragrance particles before release, and the “scented airflow” means supply of fragrance particles. The airflow that is released.

  The playback device (not shown) plays the sympathetic intake content 7 recorded on a recording medium (not shown) such as a DVD. The sympathetic intake content 7 is content including video information and scent information associated with the video information. In the present embodiment, the following description will be given assuming that the scent information includes only the air haptic information indicating the timing of presenting the air haptic A1. The display device 2 includes a projector that projects an image reproduced by a reproduction device (not shown) on a screen 6 composed of a screen or the like. The screen 6 is provided with many fine gas passage holes. The air tactile sense presentation device 4 and the scent presentation device 5 are arranged on the back side of the screen 6. The air vortex ring and the scented airflow A2 released from the air tactile sense presentation device 4 and the scent presentation device 5 are presented to the person P in front of the screen 6 through the gas passage hole of the screen 6. The person approach detection means 3 is composed of an infrared sensor or the like, detects that the person P has approached the scented video presentation device 1, and outputs the result to a playback device (not shown).

  The air tactile sensation presentation device 4 is connected to a reproduction device (not shown), and emits an air vortex ring at the timing indicated by the air tactile information read by the reproduction device to present the air tactile sensation A1. The scent presenting device 5 is connected to the air tactile sense presenting device 4 or a playback device (not shown), and the scented air flow A2 is intermittently generated after a predetermined time has elapsed since the air tactile sense presenting device 4 presented the air tactile sense A1. generate. The predetermined time is set to such a time that the inspiration of the person P is induced after the air vortex ring is released and the air tactile sensation A1 is presented.

  The sympathetic inspiration content is content that has the property that an observer is inspired by the presented content (to sympathize with it), and includes the video information and the scent information associated with the video information. Composed. It is desirable to present an image and an air tactile sense A1 to the person via the screen so as to simulate an air flow when a scent is perceived in a natural phenomenon. A person who watches the content recalls episode memory (such as memory when hit by the wind), or is stimulated by the affordance of the air tactile sensation A1 to induce conscious inspiration.

  Next, the principle from inhalation induction to olfactory presentation will be described with reference to FIGS. 1 (B), (C), and (D). The video information of the sympathetic intake content includes scenes S0 to S4 in which a flower scent drifts along with a breeze in a forest as shown in FIG. 1B, for example. In FIG. 1B, the horizontal axis indicates time. In the scene S0, the windless scene before the wind blows, for example, the trees are quiet and do not move. Scene S1 is a scene in which the wind blows and leaves and flowers sway, and scenes S2 and S3 are scenes similar to scene S1. Scene S4 is a scene in which the wind stops and the trees do not move. When a playback device (not shown) detects a person near the screen 6 by the person approach detection means 3, the playback device 2 controls the display device 2 to display the scenes S0 to S3 on the screen 6.

  FIG. 1C shows the change over time of the atmospheric pressure given to the person P by the gas released from the air tactile sense presentation device 4 or the scent presentation device 5. FIG. 1 (D) shows the time change of the intensity of inspiration and expiration of the person P. The sympathetic inspiration content includes air haptic information indicating that the air haptic A1 is presented at the timing of the scene S1. A playback device (not shown) reads the air haptic information in the sympathetic intake content, and drives the air haptic presentation device 4 at a timing when the scene S1 is played on the screen 6. As a result, when the scene S1 is displayed on the screen 6, the air vortex ring is released toward the person P in conjunction with the scene S1, and the air tactile sense A1 is given. A strong intake action is induced to the person P by the air tactile sense A1. This is the affordance that the video and air tactile sense A1 has. That is, a person knows empirically that a scent is contained in a person who feels the wind visually and feels the airflow tactilely. Since fragrance is important information for people to know the environment, there is an urge to smoke and confirm whether the fragrance is good or bad for the living body. This is affordance. Note that the air tactile sense A1 itself has the property of affording intake, but by combining the image and the air tactile sense A1, content that prompts the intake operation can be produced more reliably.

  Therefore, a person who has been breathing regularly until then is very likely to cause conscious inspiration (sniffing) within 1/2 of the breathing interval or within 2 seconds after the scene or air tactile sensation A1 is presented. high. In order to present the air tactile sensation A1 so as to encourage inspiration, it is desirable that the wind pressure changes so as to cause excitement, tension, and arousal. It is desirable to control the flow rate so that a change in wind pressure can be sensed within one second. If the scented airflow A2 is released toward the person P aiming at the intake timing, olfactory reception occurs with a high frequency. Therefore, the scent presenting device 5 intermittently generates the scented airflow A2 after the predetermined time set within 1/2 of the breathing interval or within 2 seconds after the air contact is presented by the air tactile sense presenting device 4. Release twice. The discharge interval between the two scented airflows A2 and A3 is determined as a breathing interval.

  In FIG. 1D, B1 indicates inspiration induction by the scene S1 and the air tactile sense A1, and B2 and B3 indicate sniffing operations. In this way, it is possible to present the fragrance surely and clearly by guiding the inspiration by the image and the air tactile sense A1 and presenting the scent at the estimated inhalation timing. The inhalation timing may be estimated in advance by providing an image and an air tactile sensation A1 to the subject to determine the inhalation frequency distribution with respect to time and constructing a conscious inspiration model. In addition, since it is an object of the present invention to appropriately present a scent in a scene where the scent is sensed in conjunction with the video, the scented airflow in addition to the air tactile sense presentation information is included in the sympathetic intake content. The scent presentation information indicating the timing of releasing A2 may be included, and the scent presentation device 5 may be controlled such that a playback device (not shown) generates the scented airflow A2 at the timing indicated by the scent presentation information. Of course, this scent presentation information is set so as to indicate the timing after the predetermined time from the timing indicated by the air tactile sensation presentation information.

  In the case of the air tactile sense A1, when the speed change per second is 50 cm / second or less, the probability that a skin tactile sense is perceived is reduced, and conscious exhalation (sniffing) is less likely to occur. On the other hand, when it exceeds 5 m / sec, the impact is too great, and thus the defense mechanism of the living body works, and the probability of suppressing conscious expiration is increased. Therefore, it is desirable that the air tactile sensation presentation device 4 generates an air flow that causes a speed change per second with respect to the person P in a range of 50 cm to 5 m / second to cause skin irritation.

  In addition, induction of conscious exhalation by presenting the airflow is highly effective when it is not consistent with the video content. For example, when the airflow is clearly not felt even if the airflow is presented, the induction probability of conscious inspiration is low, but when the airflow associated with the breeze is presented along with the image of the breeze blowing, Episodic memory is recalled, and conscious inspiration is likely to occur in an attempt to perceive the scent contained in the airflow. Also, in the cooking scene, when the hot air flow of the above speed change is presented together with an image or video scene where the hot air generated when the lid of hot cooking is removed, the scene is recalled and conscious inspiration is induced. The

  It is also effective to estimate the inspiratory timing in advance by giving an image and an air tactile sensation A1 to the subject and examining the excitement, tension, and arousal together with the inhalation frequency distribution over time. Whether excitement, tension or arousal has occurred can be determined by analyzing changes in skin conductance. By investigating excitement, tension, and arousal, it is possible to distinguish whether an inspiration happened or occurred consciously. If the intake that occurs consciously is extracted, the relationship between the presentation of content and the intake becomes clearer, and an accurate intake model can be constructed.

  The reliable and clear scent presentation is important as follows in order to enhance the presence of the scented image. If the scent is presented so as not to be interlocked with the intake air, the scent released from the scent generator diffuses to the surroundings. If another scent remains in front of the scene where the scent is felt, even if an appropriate type of scent is presented in the scene, a sense of incongruity is generated or a clear scent is not perceived due to olfactory adaptation by the previous scent.

  On the other hand, according to the present invention, when the inhalation time is estimated and the scent is released, not only a small amount of fragrance is used, but if a person sucks the scent, there is little scent diffused around. Therefore, even if a continuous scent scene is presented and another scent is presented in the previous scent scene, the scent remains in the surroundings before the target scene begins. Therefore, in the target scene, a clear scent suitable for the scene can be presented. That is, extremely efficient olfactory presentation can be performed with a small amount of fragrance in a scene where the fragrance needs to be switched. Since the scene and fragrance are perceived appropriately in conjunction with each other, it is effective in improving the sense of reality.

  In FIG. 1, the air tactile sensation presentation device 4 and the scent presentation device 5 are shown as separate configurations, but may be integrated. That is, it can be configured such that a single device can appropriately select and discharge a scentless air vortex ring and a scented air vortex ring. In addition to the above-mentioned scenes, the affordance-related video scenes include a breeze, a scene where the electric fan is swung, a scene where the fan is fanned toward the user, and a blast blows off the screen toward the user A scene is desirable.

  FIG. 2 is a diagram showing an experiment in which inspiration is induced by the presentation of the air tactile sensation A1, which is a feature of the principle of the present invention. Actually, the air tactile sensation A1 is presented so as to be synchronized with the video, but here, it is an experiment for showing the inspiration induction affordance of the air haptic A1 itself.

  The scent acceptance characteristics of two scent presentation methods were investigated. In Experiment 1, an air tactile sensation presentation device 4 using an air cannon was used to present a scented vortex ring to the tip of the nose at regular intervals (5 seconds). In Experiment 2, after giving the air tactile sensation A1, it was expected that inspiration would be induced by the tactile sensation, and after about 1 second when the vortex ring was applied to the face using the air cannon, the scent using the air cannon The scent was presented using the presentation device 5. After about 4 seconds, it moves to the next scent presentation. Therefore, both have an interval of 5 seconds. In Experiments 1 and 2, subjects were asked to hold the counter in their right hand and press the counter each time they felt a smell. Both experiment times are 1 minute and 40 seconds, and the number of scent presentations is 20 times. The subjects were 11 university students (8 boys and 3 girls).

  Since the purpose is to promote human inspiration by presenting the air tactile sensation A1, a thermostatic chamber laboratory in which other factors are difficult to enter was used. The room temperature is 24 degrees, the humidity is 50%, and it is a comfortable space that is neither hot nor cold for the subject. Subjects were asked to wear eye masks and earphones, and no information other than touch and smell was given.

  The air guns are both box-shaped with a side of 30 cm, the diameter of the opening is 15 cm, and the specifications can launch a vortex ring at a speed of 2 m per second. The distance to the subject is 1 m. In the scent-presenting air cannon (5 in FIG. 1), the fragrance bergamot (manufactured by Palmtree) was put in the barrel and the fragrance was released.

  FIG. 3 is a scent acceptance result using inhalation induction by air tactile sensation A1 in the experiment according to FIG. The number of scent hits of all subjects in Experiment 1 and Experiment 2 is shown. The number of hits increased when 8 out of 11 people presented the sense of smell (Experiment 2). There is a big difference in the number of hits. For three people, Experiment 1 has a higher hit rate, but the difference from Experiment 2 is small.

  FIG. 4 shows a comparison of subject average values of the number of scent hits in Experiment 1 and Experiment 2. It can be seen that Experiment 2 has more hits. After the experiment, when a questionnaire was given to the subjects, when the air tactile sensation A1 was given, many respondents said that they felt that the environment had changed and breathed unintentionally. Since this experiment was blindfolded, changes in the surroundings can only be detected in the atmosphere, but it can be considered that something happened due to the air tactile sense A1, and that spontaneous inspiration occurred.

  After the above experiment, using the configuration shown in FIG. 1, an image and an air tactile sensation A1 were presented to induce inspiration, and a scent was presented. That is, in FIG. 2, Experiment 1 for presenting a scent every 5 seconds and Experiment 2a for presenting a scent after 1 second after video and tactile sensation were presented, and the olfactory hit rates were compared. As a result, almost 100% of the subjects received the scent. That is, the effect of the present invention was proved.

  FIG. 5 proves that the display device 2 that can release gas from the screen 6 that is a component of the present invention and the psychophysiological effects of tension, excitement, and arousal when the air tactile sense A1 is presented using the device 2. Experiments are shown.

  If there is a change in the surrounding environment, such as a wind blowing or an explosion, it is often experienced that the atmospheric pressure fluctuates locally and feels an air current or an air tactile sensation A1. Therefore, when such an environment is reproduced by video and sound, an improvement in the sense of reality can be expected if it is possible to produce an air tactile sensation A1. In this experiment, as the display device 2, a screen 6 composed of a special screen having a large number of gas passage holes for allowing gas to pass through is used, and an air flow is released from the screen 6 by a method of displaying an image with a projector. The environment that can be created was evaluated, and the psychological effect when the video and the air tactile sense A1 were linked was evaluated.

  The area from which the gas is released is 10 cm in the center × 20 cm in the center in the screen 6. The air contact presentation device 4 and the scent presentation device 5 shown in FIG. 1 are attached to the back of the screen 6 so that the air vortex ring and the scented airflow A2 can be presented to the observer. The system was placed in a human interface evaluation laboratory that can measure various biological reactions, and the biological reactions during video / tactile presentation were measured. As biological responses, we focused on changes in brain hemoglobin and skin conductance. Below, it shows about the change of skin conductance.

  It is known to cause mental sweating when a person is nervous, excited or awakened. Mental sweating reflects sympathetic nervousness and high arousal levels. SCR (Skin Conductance Response) is often used as an experiment for measuring psychological tension. If tension, excitement, or awakening occurs in the presentation of the air tactile sense A1, the SCR is considered to rise.

  FIG. 6 shows the state of the experiment. Explosion scenes were used as inhalation-induced video content. When a shocking air current is perceived by the observer together with the explosion scene, the subject is strongly associated with the odor of the blast and explosives, and thus a conscious inspiration action occurs. In the figure, an air vortex ring is presented to the subject from the screen so as to be linked to the explosion scene. The upper right of the screen is a skin conductance measurement sensor (left) provided for the subject and a sensor (right) for measuring cerebral blood flow in the frontal lobe.

  There are four types of presentation conditions for the video scene and the air tactile sense A1. (1) No tactile presentation in a scene with continuous explosions, (2) No tactile presentation in a story-like explosion scene, (3) Air tactile presentation A1 in a scene with continuous explosions, (4 ) Air tactile sensation A1 is presented in a story-like explosion scene. Each video was presented for 2 minutes. After each presentation, a 1-minute break was taken to restore normality. The test subjects were four 4th graders.

  FIG. 7 shows an example of measurement results of skin conductance. The same results were obtained for the four people, although there were some changes. That is, the increase in SCR is greater in (3) and (4) with air tactile sense A1 than in (1) and (2) without air tactile sense A1. In the questionnaire after the end of the experiment, many subjects responded with the impression of “bouncing” or “disappointing” with respect to the two images (1) and (2) that do not present the air tactile sensation A1. From this result, it can be seen that air touch presentation affects tension, excitement, and arousal.

  In addition, comparing scenes (1) and (3) in which explosions are continuously connected with explosion scenes (2) and (4) having story characteristics, it can be seen that the latter affects tension, excitement, and arousal. Also, from the questionnaire results, even if the shocking blast scene (3) accompanied by the presentation of the air tactile sensation (3) is presented repeatedly monotonously, it will “get off”, “get lost”, “ “I ca n’t get it”. This is thought to be because the subject cannot obtain a fresh sensation and is not in episode memory because the air tactile sense A1 is continued. On the other hand, when the air tactile sensation A1 was presented on a story-like image (4), responses such as “surprised”, “get a fresh feeling”, “have a similar experience” were obtained. In other words, it is not necessary to present the video, but it is important to present a video scene that stimulates episodic memory and makes the blast feel like a shock.

  From the above, the sympathetic inspiration content linked with the video with experience as episode memory and the air tactile sense A1 is the stimulus that brings the most tension, excitement, and arousal, and the psychological change caused by this stimulus causes conscious inspiration to occur frequently I understand that

  Since the sympathetic inspiratory content of the present invention is ford so that the observer performs an inspiratory action, the sympathetic mirror neuron is activated at this time. Therefore, it is possible to determine whether or not the affordance is present by measuring a change in blood flow flowing through the neuron site. It is possible to produce content with high intake characteristics by determining affordance at the time of content creation. That is, the scented airflow A2 is generated after the air tactile sensation A1 is presented to the subject during the reproduction of the video information, and the scent information is added when the sympathetic mirror neuron of the subject measured at that time is activated.

  As a device for measuring the activation of the neuron, a hemoglobin concentration measuring device (NIRS: Near Infra-Red Spectoroscopy) using near infrared rays shown in FIG. 6 can be used. When the site is activated, oxygen is consumed, so that deoxygenated hemoglobin increases, and hemoglobin containing oxygen flows into the site so as not to be deficient in oxygen. Therefore, the activity of the part can be evaluated from the oxygenated hemoglobin concentration change and the deoxygenated hemoglobin concentration change, and the affordance of the content can be determined.

  The sympathetic inspiration content may be content determined that the sympathetic inhalation operation is learned by performing the scent presentation. Learning refers to increasing the probability of performing a conscious intake operation at a predetermined timing by presenting the content. The present invention can also be said to be a method of using an inspiration (metaphor) of inspiration by an image and an air tactile sense A1 instead of an explicit inhalation operation instruction as shown in FIG. The affordance of the content encourages inspiration, but when the scent is actually presented at the prompted timing, the user associates the suggestion and inhales at the predetermined timing. In order to determine what has been learned, a test subject is prepared in advance, a questionnaire survey is performed after the presentation of the scent, and the frequency of perception of the scent increases. Moreover, what is necessary is just to verify that the said brain activity is activated by the repeated presentation of content.

  In addition to the motor language area (broker area), the prefrontal orbital area near the olfactory bulb where olfactory processing is performed is also effective as a site for measuring empathic mirror neurons. This part has a close cooperation with the limbic system, and functions to coordinate and integrate the activities of the limbic system. Therefore, when the site is stimulated by the presentation of the sympathetic inspiration content, the suppression force is reduced, and sniffing that cannot suppress the impulse is likely to occur. Therefore, learning may be determined by verifying this operation.

  In addition, when the air tactile sense A1 is presented during the reproduction of the video information, a scented airflow A2 is generated, and when the subject's sympathetic intake action is learned, the scent information is added to produce the content. Also good.

  Specifically, a subject group is prepared in advance, and sympathetic intake content is presented. That is, an image in which an air current is felt is presented, and an air tactile sense A1 is presented at a timing consistent with the content of the image. Thereafter, the scented airflow A2 is generated according to the intake timing estimation model. In addition, in the said model, the model which generate | occur | produces the scented airflow A2 within 1/2 or 2 second of a person's breathing interval after presentation of air tactile sense A1 as mentioned above is desirable. At this time, the above-mentioned olfactory hit rate is measured. Then, when this olfactory hit rate is high, scent information is added on the assumption that the sympathetic intake action is learned.

Second Embodiment Next, a second embodiment of the present invention will be described. FIG. 8 is a diagram showing a configuration in the second embodiment of the present invention. The description will focus on the differences from the first embodiment shown in FIG. In FIG. 8A, 1 is a scented video presentation device, and 2 is a display device having a screen 6. Since the display device 2 is the same as that of the first embodiment, detailed description thereof is omitted here.

Used.

  The air tactile / scent presentation device 10 introduces an airflow generating device 15 that generates an airflow, a casing 11 that compresses air released from the airflow generating device 15, and an airflow generated from the airflow generating device 15 to the housing 11. A duct structure 18 and a fragrance supply device 14 that discharges liquid fragrance into fine particles in the housing 11 are provided. The airflow generation device 15 includes an impeller mechanism 16 that generates atmospheric pressure and an air filter 17. The airflow generation device 15 rotates the impeller mechanism 16 at a timing indicated in the air tactile information to generate an airflow. At this time, as shown in FIG. 8E, the impeller mechanism 16 is rotated so that the air pressure becomes intermittently high. The housing 11 is provided with an opening on the front side, and the opening is covered with a screen 6 provided with a number of gas passage holes. A plurality of blade mechanisms 12 that rotate about the rotation shaft 13 are provided in the housing 11.

  The air flow generated from the air flow generation device 1 flows as indicated by a one-dot chain line 19 and is discharged from a hole provided in the screen 6. At this time, the direction of the airflow can be controlled in a predetermined direction by rotating the blade 12. If the position of the person is detected by a person detection sensor not shown in the figure, an air flow can be presented toward the person. A 20 dot-dash line indicates that gas is released vertically from the screen, and a 21 dot-dash line is released in an oblique direction.

  The perfume supply device 14 can appropriately release a gas with a fragrance and a gas without a scent by discharging the fine particles of the fragrance in pulses. The fragrance supply device 14 releases the fine particles of the fragrance into the casing 11 after a predetermined time has elapsed since the airflow generation device 15 generates the airflow. The predetermined time is set in the same manner as in the first embodiment. As a result, as shown in FIG. 8 (C), an air antenna having no scent can be presented at the first atmospheric pressure mountain generated from the airflow generator 1, and the scent can be presented at the next two atmospheric pressure mountains. it can. Thus, you may use the apparatus which presents one air tactile sense A1 as a fragrance presentation apparatus.

  In the above-described embodiment, the air tactile sense A1 and the scented airflow A2 are generated during the reproduction of the video information. However, the present invention is not limited to this. For example, you may make it generate air tactile sense A1 and scented airflow A2 during reproduction | regeneration of sound information.
