JP5074610B2 - Educational system for aversion to temptation substances that emit fragrance - Google Patents

Description

The present invention relates to a system for educating the aversion preference of harmful tempting substances that emit scents.

Tobacco toxicity has been pointed out, but the smoking rate has not yet decreased sufficiently. When I was young, I was curious and learned the charm of the harmful substance, which has a great impact on my life. In Japan, smoking is mainly regarded as a problem, but in Canada, drugs such as marijuana are not prohibited by law, so they are sold to general coffee shops. In the United States, it is illegal to have marijuana, but it is not difficult to obtain because there are many ways to obtain it. For this reason, it is not uncommon for young people such as high school students to smoke such harmful substances.

In this way, not only in Japan but also around the world, there are many cases where young people smoke harmful substances such as cigarettes and marijuana only with pleasure. This seems to be due to the lack of awareness that these drugs are harmful. Therefore, there is a need for a method of educating early on that it is bad to take something harmful to the body. Therefore, there is a need and possibility of a system that educates preferences about substances that emit fragrances.

The relationship between the present invention and the conventional invention is as follows.
As a technology related to tastes, for the purpose of providing a television receiver with a scent-generating device with excellent operability, convenience, and controllability, fragrances tailored to your preferences, emotions, mental states, and usage conditions are used. A technique of supplying with controlled strength is disclosed in Patent Document 1.

As a technique related to preference education, Patent Literature 2 discloses an education system that allows a child to learn information related to fragrance, such as the name of the fragrance, the production area of the fragrance, cooking using the fragrance, and the method of producing the fragrance. Further, Patent Document 3 discloses a method and an apparatus for training a sense of sound such as a relative tone, an absolute tone, and a tonality by sensory stimulation with sound and scent.

Patent Document 4 discloses an education system for improving the motivation for studying, which is expected to increase the willingness to learn a language by giving a scent to a person who wants to learn a language when stimulating visual or auditory senses. ing.

As a technique for diffusing and presenting scents, Patent Document 5 discloses a system that can present the scent of an atmosphere displayed by a video so as to be synchronized with video, audio, words, and the like.

As described above, there are inventions relating to methods and apparatuses for using fragrances in education such as language, music, and related knowledge. There are also methods and devices that use scents to enhance the realism of video. However, there are no invention examples regarding a system that educates preferences for substances that generate scents, and particularly an education system that nurtures anaerobic characteristics for harmful substances that generate scents.

An object of the present invention is to educate the preference of harmful seductive substances having a specific scent and to maintain the educational effect for a long period of time. In particular, in order to protect young people from tobacco and drugs that are harmful to health, a system to educate children so that when they smell the scent of the substance, they do not take the substance and can take repellent action from the substance. For the purpose.

<Means 1>
The aversive preference education system 1 for a seductive substance that emits a scent according to the present invention is described in association with, for example, FIG. 1 and FIG. 2, detoxifies or reduces harm as a scent that expresses a harmful seductive substance. A scent presentation device 2 that presents a similar scent having an olfactory characteristic similar to the substance, a sensory stimulus presentation device 5 that presents an unpleasant sensory stimulus as a stimulus that affects the disgusting preference of the substance, and the scent presentation device And the control device 6 that controls the sensory stimulus presentation device, and the control device performs control so as to present the similar scent and the unpleasant sensory stimulus as one body.

The unpleasant sensation stimulus uses a stimulus that has been determined to provoke discomfort in advance. Specifically, the stimuli are the visual sense 51, the auditory sense 53, the tactile sense 54, the olfactory sense 55, the somatic sense 56, and the like. The determination of discomfort can be made using the determination means 3 using sensitivity information processing or the like. By presenting the unpleasant sensation stimulus to the subject, acquiring data with the biological reaction measuring means 4, and statistically analyzing the data, a sensation stimulus that most people feel unpleasant can be produced. As the biological reaction measuring means 4, it is possible to measure an electroencephalogram, a cerebral blood flow, a fingertip pulse wave, an electrocardiogram, a sphygmomanometer, a skin conductance, or the like, or a questionnaire.

In this way, sensory stimuli that are determined to be uncomfortable are produced in advance and presented together with the scent when educating, so that substances that generate a specific scent can be disliked.

Examples of substances harmful to health include tobacco, marijuana, and narcotics. In order to express these harmful substances, the learner is presented with a harmless or safe pseudo-scent 21 that is close to the scent of the substance, and at the same time, the stimuli (51 to 56) determined that the brain arouses innocence. Present. By repeating this training, the learner is kept away from or away from the location of these harmful substances.
Thus, by presenting stimuli that the brain feels uncomfortable with a scent that expresses a substance harmful to health, tobacco and drugs can be disliked.

<Means 2>
For example, in the system described in the means 1, the unpleasant sensation stimulus is a visual image based on an image. Stimulus, auditory stimulation by sound, tactile stimulation by energization, stimulation of semicircular canal stimulation by energization, or a combination of these stimulations, and it is determined in advance that arousing an unpleasant sensation, It is also characterized by stimuli that can control the intensity of disgust.

<Means 3>
In the system according to either the means 1 or the means 2, the education system 1 for aversion to seductive substances that emit a scent according to the present invention will be described with reference to FIGS. 1 and 2, for example. The unpleasant sensation stimulus is a stimulus in which the level at which unpleasantness is aroused by the determination level hierarchizing unit 31 is hierarchized, and the control device 6 performs the unpleasant sensation stimulus according to the input level during learning. It has a function of controlling the intensity of disgust by selectively presenting it.

The unpleasant sensation stimuli (51 to 56) can be selected and presented during learning by layering in advance. For example, since it is necessary to present a stimulus with a strong discomfort to a learner who wants to strongly stop cigarettes, the discomfort sensory stimulating means (51 to 56) are arranged in a hierarchical manner, and how unpleasant the stimulus is. Can be selected by input to present the level of discomfort stimulus.

<Means 4>
The aversive preference education system 1 for a seductive substance that emits a scent according to the present invention will be described with reference to FIGS. 1 and 2, for example, in the system according to any one of the means 1 to 3. At the time of learning in which the scent and the unpleasant sensation stimulus are presented as one body, the biological reaction is measured by the biological reaction measuring means 9, and the control device 6 compares the measured data with the typical biological reaction data 8 measured in advance. Educational effect evaluation means 11 is provided, and an unpleasant sensory stimulus is presented so as to control the intensity of disgust based on the evaluation.

The measurement of the biological reaction includes measurement by an electroencephalogram, cerebral blood flow, finger plethysmogram, electrocardiogram, blood pressure, skin conductance, and questionnaire. Using many subjects, it is possible to obtain these measurement data for sensory stimulus presentation in advance, statistically process the data, extract typical biological reactions, and create a database. It is possible to evaluate the educational effect of the preference by acquiring biological reaction data with respect to presentation of unpleasant sensation stimuli of a person (learner) to be educated and comparing it with the typical biological reaction data. Under this evaluation, it is possible to control the presentation of sensory stimuli determined to provoke discomfort.

<Means 5>
The aversive preference education system 1 for a seductive substance that emits a scent according to the present invention will be described with reference to FIGS. 1 and 2, for example, in the system according to any one of the means 1 to 3. At the time of learning in which the scent and the unpleasant sensation stimulus are presented as one body, the biological reaction is measured by the biological reaction measuring means 9, and the biological reaction measurement data when the explanatory data other than the measurement data and the unpleasant sensation stimulus are presented The educational effect is evaluated by comparing with 15.

It is possible to control a sensory stimulus determined to provoke discomfort under the educational evaluation. That is, if it is evaluated that the educational effect is sufficient, presentation of unpleasant sensory stimulation can be stopped at that time. Further, when the educational effect is insufficient, it is possible to continue presentation of unpleasant sensation stimulation or increase the level of unpleasantness.

<Means 6>
Aversion preference sex education system 1 temptation material that emits fragrance of the present invention, for example, FIG. 1, will be described in association with FIG. 2, in the system according to any one of means 5 from the device 1, the unpleasant sensory stimuli, a visual stimulus by the image, in order of unity of the similar aroma and the unpleasant visual stimuli as obtained, et al, presenting the aroma from the screen where the unpleasant visual stimulus is displayed Features.

By providing a small hole on the screen 29 that does not affect the image and providing the scent presentation device 2 on the back side of the screen, the scent can be presented to the learner's nose.

<Means 7>
In the system according to any one of the means 4 or 5 described below, for example, the aversive preference education system 1 for a seductive substance that emits a scent according to the present invention will be described with reference to FIGS. As the biological reaction measuring means, means for measuring a hemoglobin concentration change in brain tissue or a skin conductance change is used.

<Effects of Means 1 and 2>
By presenting the scent expressing the scenting substance and the unpleasant sensory stimulus determined to be unpleasant, the brain stores the scented substance together with an unpleasant impression. Episodic memory with fragrance has the characteristic of being retained for a long period of time, so preference education for the substance is extremely efficient. For example, if the scent of tobacco and a picture of lung cancer are memorized, the image of lung cancer will be recalled when you smell the scent of tobacco, avoiding smoking sites.

It is possible to learn to hate seductive substances harmful to health in a safe way. Even if you take a cigarette or narcotic and then try to notice the problem and stop it, it will be difficult to stop it because of the drug action (such as addiction). However, in the present invention, a similar scent that removes or reduces toxicity from harmful substances is used, and the scent is memorized in the brain with an unpleasant impression at an early stage. There is a deterrent effect.

Vaccines are drugs that have been made from pathogens that have lost or are not toxic, and inject antibodies into the body by injecting weak pathogens to make them less susceptible to infections. Has an effect similar to that of a vaccine. By having the brain memorize early, the effect is retained for a long time.

<Effect of means 3>
By inputting a level that arouses discomfort, sensory stimuli are selected and presented, so that appropriate sensory presentation can be presented in accordance with the learner's request. For example, if the learner is sensitive to discomfort, a sensory stimulus determined to have a low discomfort is sufficient, and if the smoker is aiming to quit smoking, the discomfort may be It can be adapted to the needs of learners, such as using high sensory stimuli.

<Effects of Means 4, 5, and 7>
When learning is presented in conjunction with the scent expressing the object of education and the determined unpleasant sensation stimulating unpleasantness, the biological reaction is measured and the educational effect is evaluated, so if the educational effect is sufficient, The sensory stimulus presentation can be stopped at that point, and if the educational effect is insufficient, the sensory stimulus presentation can be continued or the level of discomfort can be increased. That is, there is an effect that an appropriate unpleasant sensory stimulus can be presented.

<Effect of means 6>
When using video as an unpleasant sensation stimulus that arouses discomfort, the fragrance is released from the unpleasant video, so the harmful video and fragrance are combined and the harmful seductive substance expressed as the scent is disgusting It is easy to remember with taste. It provides an efficient educational system for avoiding youth from harmful seductive substances.

Embodiments of the present invention will be specifically described.

FIG. 1 shows an embodiment of the present invention. Reference numeral 1 denotes a taste education system for substances that emit incense (a harmful substance non-intake education system). Here, it demonstrates as a system which dislikes a tobacco for convenience. 1 includes a device 2 for presenting a scent and a sensory stimulus presentation device 5 determined to cause discomfort.

From 2, the scent expressing the educational object is released. The operation will be described. Reference numeral 18 denotes a container for a fragrance, which contains a fragrance for expressing tobacco. The container is heated by an electric heating coil Coil. Driv is a drive device and is controlled by the computer 6. When the container is heated by the coil, the fragrance 21 expressing tobacco is vaporized, and the scent Fg1 is released from the hole of the container. Reference numeral 58 denotes a blower that discharges airflow forward from the gas outlet. The scent Fg1 is presented to the learner P.

From 5, the sensory stimulus determined to provoke discomfort is presented. First, the case of using a visual stimulus will be described. 51 is a video display device, and 52 is a video database determined to cause discomfort. The computer 6 controls the release of the scent Fg1 expressing the cigarette and the display of the video determined to cause discomfort in an interlocking manner.

An image determined to provoke discomfort can be prepared by conducting a subject experiment in advance. Sub is the subject. Reference numeral 7 denotes an image that gives discomfort or fear, for example, an operation image of lung cancer or an image having a high degree of discomfort due to harm caused by cigarettes. Reference numeral 4 denotes a means for measuring a biological reaction during or after the video viewing, that is, at the time of determining an unpleasant stimulus. EEG, cerebral blood flow, finger plethysmogram, electrocardiogram, sphygmomanometer, etc. can be measured, and the intensity of the stimulus can be analyzed from the change of the measured value in the stimulus presentation.

By comparing this result with the questionnaire result, it can be determined whether or not the viewing video is unpleasant. 3 is a means for determining discomfort. If data is acquired with the cooperation of many subjects and statistical analysis is performed, it is possible to determine images that the general public feels uncomfortable. Further, if a more precise analysis is performed using a sensitivity information processing technique or the like, a level can be set for the discomfort level, and 31 is a hierarchical processing means for the discomfort level.

In the figure, a fragrance representing the tobacco, the screen of the video display device 51, a human lung images who died of normal lung video and long smoke lung cancer appears in contrast, from the speaker 13, Narration: “The top cause of death for Japanese people is cancer. Among them,“ lung cancer ”is the top. "Is flowing. Pathological anatomy images are also effective for making the general public uncomfortable. Watching videos while smelling the scent of cigarettes can help Learner P increase their imagination about harmfulness.

Moreover, as another image determined to provoke discomfort, a horror image 7 or an image that creates a symptom called virtual reality sickness using virtual reality technology is also possible. When presented with unnatural movements that differ from reality, for example, 3D images in which the image suddenly jumps or rotates, symptoms similar to motion sickness can be created. By causing sickness while presenting the scent, the substance that emits the scent can be disliked.

When people feel sick, they are accompanied by facial pallor, cold sweat, headache, increased salivation, nausea, vomiting, and fatigue. It determines whether or not felt the discomfort, such as drunkenness, or, to measure the strength of dizziness and upset is possible by performing a question about the these subjects. For example, I feel uncomfortable, tired, flirting, tired eyes, increased saliva, cold sweat, dizziness, blurred eyes, heavy head, I can't concentrate, You can ask if your surroundings are rotating, nauseous, your chest is clogged, or you feel cold. Quantification is also possible by accumulating these complaints multiplied by a weight representing their degree.

Videos and other sensory stimuli can also be downloaded from the Internet. 10 is the Internet, and 12 is a communication device. As described above, the downloaded content may be previously determined to be unpleasant using a subject, edited so that it is determined to be uncomfortable, and used for education.

It is also possible to use sensory stimuli determined to arouse discomfort other than video. The case where the olfactory stimulus 55 determined to arouse discomfort is used will be described. The container 19 contains a fragrance 55 determined to cause discomfort. Examples include sulfur, hydrogen sulfide, spoilage odor, feces odor, malodor including ketone bodies, and mold odor. Since it is intended to give psychological disgust, it is desirable to use a low concentration that does not have a physiological adverse effect on the human body. When the container is heated, an unpleasant scent Fg2 is released from the hole, and is presented to the learner P together with the scent Fg1 expressing tobacco by the airflow from the blower 58. The scent expressing tobacco is memorized as an unpleasant scent.

It is also effective to emit colored smoke at the same time in order to create a sensory stimulus that arouses discomfort. 57 is a means for generating colored smoke. For example, when a fragrance comes in mixed with green smoke, it makes you feel uncomfortable because it reminds you of how the toxic substance burned. Tobacco is a unique scent that can be disliked by ordinary people, but many people recognize it as an unpleasant scent by mixing it with an unpleasant scent or adding a green or yellow color.

Next, a case where an auditory stimulus determined to cause discomfort is used will be described. Reference numeral 53 denotes a sound database determined to provoke discomfort. In order to stimulate the sense of hearing and make it uncomfortable, it is effective to play an unpleasant high-frequency sound of 17 kHz or more called “mosquito sound” from the speaker. The human body has no physiological effects and can be psychologically unpleasant. It is also possible to present low frequency sound with high output.

Next, a case where a tactile stimulus determined to arouse discomfort is used. 54 is a tactile database determined to provoke discomfort, 56 is a device for electrically stimulating the semicircular canal using the 56 data, and 59 is a semicircular canal stimulating electrode. 54 and 56 are controlled by the computer 6. In virtual reality and the like, a method of electrically stimulating the cerebral cortex vestibular cortex or the semicircular canal is used to control the sense of balance. Electrical stimulation of the cerebral cortex vestibular cortical areas, "vertigo" occurs, it is possible to feel uncomfortable.

In addition, as the tactile stimulus 54, a slight pain or numbness in the skin can be caused by an electric current. These discomfort determinations 3 can also be made by measuring 4 questionnaires and biological reactions. In this way, it is possible to present the stimulus determined to provoke discomfort together with the scent that expresses the education target substance. These sensory stimuli that arouse discomfort may be used alone or in combination. When combined, it creates a strong and unpleasant sensory stimulus due to a synergistic effect.

Next, a description will be given of a method of detecting the state of the learner P, evaluating the educational effect, and using it for the presentation of the sensory stimulus when the sensory stimulus determined to provoke discomfort is presented. 9 is a means for measuring the biological reaction of the learner P, and 60 is a biological reaction measurement electrode. For 9, the measuring means, questionnaire, etc. described in 4 can be used. That is, it comprises a brain function measuring device (electroencephalograph, cerebral blood flow measuring device), biological reaction measuring device (skin conductance measuring device, finger plethysmogram measuring device), and the like. Specific examples will be described later in detail with reference to FIGS. 3, 4, and 5.

From 4, it is possible to statistically process data when sensory stimuli that arouse discomfort are presented using a large number of subjects, and to extract typical biological reactions. Moreover, the extraction result can be made into a database. 8 is a means for that.

The state of the learner P can be monitored by comparing the biological reaction acquired during learning with 9 and the biological reaction retrieved from 8. 11 is an educational effect evaluation means for this purpose. As a result of the educational evaluation, if it is evaluated that the educational effect is sufficient, the sensory stimulus presentation can be stopped at that time. If the educational effect is insufficient, the sensory stimulus presentation can be continued. In addition, if the stimulus is too weak and learning is insufficient, education can be provided with stronger and more diverse stimuli.

The amygdala is known as an organ that controls emotions and tastes, but plays a role as a control tower that stores ingested taste and olfactory sensations associated with pleasure and discomfort. As described above, when an unpleasant stimulus is presented as a set while presenting a scent, the brain stores the scent in association with emotions. It is known that memory relating to fragrance is less attenuated than memory of video, and in particular, memory related to a scent that is unpleasant or life-threatening is likely to be retained for a long period of time. Also, as a feature of scent memory, the brain requires less procedure to recall. Therefore, the present invention does not say that he dislikes all the reasoning, but he feels disliked at the moment he smells the scent. If you don't like the substance you learn, you won't take it.

Living organisms have a particularly strong learning effect on discomfort, and in mouse experiments, mice were given a sweet scent and taste that they liked, and then injected with calcium chloride, which causes temporary upsets in the body. There are reports that it will never get close to the food again. In other words, once it is recognized as an unpleasant thing that adversely affects life, the memory is thought to be retained for a long time. The same applies to people.

For example, stool is something you don't like or dislike for infants, but as parents learn that they are dirty as they grow up, their children will recognize stools as dirty and disliked, For ordinary people, this memory will last a lifetime. In this embodiment, the same memory as that for tobacco and narcotics is artificially performed using multimedia.

Here, the harmful substances you want to hate are cigarettes, but you can also make them narcotics. In the case of tobacco, the scent of tobacco itself is not harmful, so the scent of tobacco can be used, but in the case of narcotics, the scent itself may be harmful, so a similar scent is used.

FIG. 2 shows another embodiment of the present invention. Reference numeral 1 denotes a taste education system for substances that emit incense (a harmful substance non-intake education system). It shows a configuration that can present sensory stimuli from the back side of the screen and a means for measuring the biological reaction and evaluating the educational effect.

A description will be given centering on differences from FIG. For 51, an image display device provided with many fine holes is used. The scent presentation device 2 and the speaker 13 are used on the back side of the device. The scent and sound pass through the screen 29 and are presented to the subject Sub and the learner P ahead. In this system, the information presenting means 14 (indicated by a broken line) for explaining the educational object to the learner and the apparatus 5 for presenting the sensory stimulus determined to provoke discomfort with the scent of the educational object as in FIG. (Dashed line).

The configuration of 14 will be described. In 51, an image 23 explaining an educational object (such as a cigarette) can be displayed. 13 can present a voice explaining the goods. 2, the scent Fg1 obtained by vaporizing the fragrance 22 expressing the substance can be released.

The configuration of 5 is the same as in FIG. 52 can be used as a visual stimulus that arouses discomfort, 53 as an auditory stimulus that arouses discomfort, 55 and Fg2 as olfactory stimuli that arouse discomfort, 54, 56, 59, etc. as tactile stimuli that arouse discomfort. These may be used alone or in combination.

For the evaluation of educational effects, a method can be used in which a biological reaction is measured when an object is described, a sensory stimulus determined to provoke discomfort is presented, the biological reaction is measured, and the two are compared. . Reference numeral 15 denotes a biological reaction measuring means at the time of explaining the object, which can score reaction characteristics. Reference numeral 9 denotes a learner's biological reaction measuring means, which can score reaction characteristics. 16 is a means for comparing scores, and 11 is a means for evaluating educational effects from the difference in scores. If the education is sufficient, the unpleasant stimulus is stopped, and if it is insufficient, the unpleasant sensory stimulus presentation can be continued as in FIG.

FIG. 3 shows another embodiment of the present invention. In the preference education system 1 for a substance that emits incense, based on the result of the education effect evaluation means 11, the sensory stimulus determined to provoke discomfort is controlled and learned. To provide more appropriate education tailored to the characteristics of person P.

A different part from FIG. 2 is demonstrated. 11 shows the educational effect depending on whether the result of the biological reaction measuring means 15 at the time of the object description and the result of the biological reaction measuring means 9 at the time of learning are compared with the result of the comparison exceeding the reference value. It is comprised by the determination means 17. If it is determined by 17 that the standard is exceeded, the learning is terminated, and if the standard is not satisfied and the education is determined to be insufficient, the level at which it is determined that the discomfort is aroused is raised and a strong discomfort stimulus is presented.

Moreover, the result of the biological reaction measurement means 9 measured at the time of learning may be compared with typical biological reaction data when a sensory stimulus that arouses discomfort is presented. The typical biological reaction data can be obtained by statistically processing the results measured using the biological reaction measuring means 4 with the cooperation of many subjects in advance. If the comparison means 16 determines that the educational effect is sufficient, the unpleasant stimulus presentation is stopped, and if it is determined that the educational effect is not insufficient, a strong unpleasant stimulus is presented.

In FIG. 1, an embodiment using a cerebral blood flow measuring device as the biological reaction measuring means 4 will be described. For the measurement of the cerebral blood flow, a near infrared hemoglobin measuring device NIRS or the like can be used. The apparatus can measure the amount of blood flowing into a predetermined part of the brain, oxygenated hemoglobin concentration, deoxygenated hemoglobin concentration, and the like. When the brain is active, oxygen is consumed, so if the blood flow is constant, oxygenated hemoglobin decreases and deoxygenated hemoglobin increases. In addition, blood flow is increased.

FIG. 4 is an example of experimental results obtained by measuring changes in intracerebral tissue hemoglobin. When an unpleasant video (sentence) is presented together with a scent, a remarkable biological reaction occurs, which indicates that the educational effect can be evaluated by processing the biological reaction data.

(A) shows the result of measuring the hemoglobin concentration in the frontal lobe at the time when the explanation of the cigarette was displayed for 30 seconds (no fragrance), starting from a state where the spirit was stable. The top is the right brain, and the bottom is the left brain. In general, when the brain is activated, oxygen is consumed, so the oxygenated hemoglobin concentration (O2Hb) decreases, and an increase in the deoxygenated hemoglobin concentration (HHb) that has lost oxygen may be observed. cHb is the total-hemoglobin concentration, and TOI (Tissue Oxygen Index) indicates the ratio of oxygenated hemoglobin to total-hemoglobin. When the brain is active, there may be a decrease in TOI. This is because oxygen is consumed.

In this test subject's case, in (a), the left and right brains do not show any characteristic fluctuations compared to when they are calm. On the other hand, (A) shows the result of measuring the hemoglobin in the brain tissue of the frontal lobe at the time when the explanation of the cigarette was displayed for 30 seconds together with the scent, starting from a state where the spirit was stable. A decrease in O2Hb, an increase in HHb, and a decrease in TOI can be seen. Comparing (a) and (b), it is possible to quantify brain activity by presenting unpleasant scented character stimuli. Just saying unpleasant texts means that the response is small, and the presentation of scents and unpleasant texts means that the response is great (the brain becomes active). It is shown that.

As the feature quantity to be compared, the fluctuation speed of each component, the amplitude of the TOI (maximum, minimum width; delta1, delta2), etc. can be used. For example, if delta 2 / delta 1> 3 continues for a predetermined number of times, learning can be terminated assuming that discomfort frequently occurs due to stimulation.

By attaching multiple measurement sensors to the surface of the brain, it is possible to estimate which part of the brain is working. In addition, for the deep part of the brain, such as the amygdala, which is said to govern emotions, the activity state of the brain can be estimated using a device such as fMRI.

Thus, when a sensory stimulus determined to provoke pleasure or discomfort is presented, a portion where the brain is activated can be obtained from many subjects and used as typical biological reaction data. The educational effect can be evaluated by comparing the biological reaction data acquired from the learner with the typical biological reaction data. Here, as a comparison method, the brain activity state is a two-dimensional or three-dimensional image, and the amount of overlap between a typical brain activity image obtained from many subjects and a learner's brain activity image is calculated. It is possible to evaluate whether or not there is a predetermined stimulus in the learner's brain.

In addition, a method is also possible in which feature quantities are extracted from each biological reaction, expressed in vectors in a multidimensional space, and inner products are calculated. In addition, a method for comparing similarities using a multivariate analysis method can be used.

In FIG. 1, an embodiment using a skin conductance measuring device as the biological reaction measuring means 4 will be described. It is known that when a person is nervous or excited, they can cause mental sweating. Mental sweating reflects sympathetic nervousness and high arousal levels. The SCR (Skin Conductance Response), which is a reaction component of SCA (Skin conductance Activity), is often used as an experiment for measuring psychological tension.

FIG. 5 is an example of experimental results obtained by measuring changes in skin conductance. When an unpleasant video (text) is presented together with the scent, the living body is tense and sweats, so the skin conductance increases. Since it is a remarkable biological reaction, it is shown that the educational effect can be evaluated by processing the data.

In the figure, for the first 30 seconds, there was no fragrance, and the harm of cigarettes was explained only by text images. Subsequently, a break was taken for 30 seconds, and the harmfulness of the scent along with the scent of the cigarette was presented in a text image for 30 seconds. In the case of only character images, no significant change in skin conductance was obtained. The subject replied in the questionnaire that he / she did not feel nervous or excited enough to understand the sentence.

On the other hand, when the scent of cigarettes that provoke discomfort was presented and the harmful effects were explained in text, the skin conductance reacted sensitively. When asked about the impression of the subject after the experiment, there was a reply that there was a sense of reality in the harmfulness. Skin conductance is a technique used in lie detectors and is sensitive to psychological tension and excitement. The learning effect can be quantified by comparing the maximum value of the skin conductance between the case where a simple description of a harmful substance is presented and the case where an unpleasant stimulus is presented together with a scent.

In this figure, the learning effect is estimated by the ratio (EF) of the skin conductance change amount delta. When this EF is 3 or more, for example, it is determined that the learner has formed a strong mental image that recognizes harmful substances as unpleasant, and learning can be terminated.

Although an example of cerebral blood flow experiment and skin conductance has been shown, other biological reaction measurements such as electrocardiogram, fingertip pulse wave, blood pressure, and skin temperature can be used. When the imagination about harmfulness increases by presenting sensory stimuli determined to be unpleasant, heart rate, blood pressure, and skin temperature increase. If the intensity of the mental image of discomfort is estimated comprehensively from multiple biological reactions, the accuracy increases.

FIG. 6 is a system configuration example in which a display device capable of presenting a scent from the back side of the screen is used in another embodiment of the present invention, and a plurality of harmful substances are disliked by a single device. Fig. (Ii) is a front view of this system, and Fig. (I) shows a cut surface indicated by a broken line in Fig. (Ii). In FIG. (I), three types of scent presentation devices are provided on the back side of the display device 51 with holes.

Many small holes are provided between the pixels of the thin screen 29. The scent can be released from this hole while displaying the video. The scent presentation device 2 includes a box (scent discharge part 27) containing a scent element, a duct 26, and a portion 59 that generates atmospheric pressure. The air pressure generating unit 59 includes a blower 58 using a fan. The air filter 25 removes dirt and dust, and the air is sent to the scent discharge part by a duct, and the air pressure on the back side of the screen is increased to release the scent.

The fragrance release unit 27 contains a fragrance (21) that resembles a harmful substance that expresses the educational object, and a fragrance (55) that has been determined to cause discomfort. The three types of fragrance can be switched with the switch SW. In the figure, in order to dislike drugs, a scent similar to drugs and an unpleasant scent are shown.

In FIG. (Ii), the camera 28 captures the position of the learner. Camera images can also be sent to remote instructors. If the learner's position is off the screen, the scent will not reach, so you can instruct him to adjust the position. When you select a subject you want to hate, a hazardous substance non-intake education program starts. We make cigarettes and narcotics a similar scent and present them in combination with five-sensory stimulus information determined to be unpleasant and dislike them.

Regarding scent presentation, it is desirable that a small amount of scent is intermittently released from the place where an image determined to provoke pleasure or discomfort is displayed so that the scent does not cause olfactory fatigue. .

When the scent is presented intermittently at intervals of about 1 second, olfactory fatigue is suppressed, so that the learner can feel the scent for a long time. The time required for the brain to learn and memorize mysterious or unpleasant visual stimuli requires several minutes to several tens of minutes. If olfactory fatigue occurs during this time, the scent cannot be linked to the educational object. However, by presenting a mysterious or unpleasant video while intermittently presenting the scent while preventing olfactory fatigue, the substance that generates the scent and the mysterious or uncomfortable are likely to be linked to facilitate learning. By presenting the scent intermittently, it is possible to prevent olfactory fatigue while presenting a pleasant or unpleasant image, so that the substance that emits the scent can be strongly remembered with preference.

With a monitor camera or the like, it is possible to detect that the learner is viewing a pleasant or unpleasant image, and at that time, it is possible to present a scent that expresses the educational object.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention in the implementation stage. Further, the above-described embodiments include various stages of the invention, and may be implemented by an appropriate combination. Furthermore, the constituent elements of the above-described embodiments can be omitted as appropriate based on the purpose, or can be supplemented by well-known conventional techniques.

(1) It can be used for education that does not ingest harmful substances such as tobacco and drugs. By remembering the odors peculiar to these harmful substances as unpleasant during childhood, it helps to reduce the chances of exposure to these for a long time. It can be used as a non-toxic substance education system at schools, medical institutions, and insurance centers. Children are more olfactory and more sensitive than adults, so the educational effect of this system is particularly high.

(2) It can be used as a support system when smokers quit smoking. The simplest system can be used at home because it can be composed of a personal computer, a scent presentation device, and the Internet. A service that distributes scent recipes representing educational objects and sensory stimuli (images, sounds, scent recipes, etc.) determined to be uncomfortable over the Internet is also possible. Based on the recipe, the system can reproduce the scent and present it to the learner. Moreover, it can be used as a support system when a drug experienced person cuts off a drug and rehabilitates it.

(3) As a development system related to the present invention, a system that likes a substance that emits a scent can be considered. It is possible to provide a system that likes vegetables by presenting sensory stimuli determined to be pleasant along with the fragrance of vegetables to children who do not like vegetables. Can be installed at home or kindergarten.

In an embodiment of the present invention, it is a harmful substance non-ingestion education system using fragrance. In another embodiment of the present invention, in a harmful substance non-ingestion education system using a scent, a configuration capable of presenting sensory stimulation from the back side of the screen and a means for measuring a biological reaction and evaluating an educational effect are shown. In another embodiment of the present invention, it is shown that in a harmful substance non-ingestion education system using a scent, a more appropriate education that matches the characteristics of the learner can be implemented using a means for evaluating the educational effect. It is another Example of this invention, and is an example of the change measurement result of the tissue hemoglobin in a brain at the time of using a cerebral blood flow measuring device for the biological reaction measuring means 4. It shows how brain activity becomes active when video (text) that arouses discomfort with scents is presented. It is another Example of this invention, and is an example of the measurement result at the time of using a skin conductance measuring device for the biological reaction measuring means 4. FIG. When a video (sentence) that arouses discomfort with the scent is presented, the living body is tense and sweating. In another embodiment of the present invention, a display device capable of presenting a scent from the back side of the screen is used to dislike a plurality of harmful substances with one device.
