Description

The present invention relates to a public information presentation device using a video display device. The present invention also relates to a public information presentation device that can present a chemical substance such as a scent to a passerby in conjunction with an image.

In recent years, video display devices have advanced large screen, thin and high definition technologies, and can display powerful or realistic video. For example, a thin display device using liquid crystal, plasma, and the like, and an ultra-large screen display device using LEDs are known. In addition, an ultra-thin and high-definition video display device using an organic EL element can be manufactured.

Such a thin, large-screen display device can be applied not only to conventional television receivers and computer peripheral devices but also to public information presentation devices such as the electronic street advertising (digital signage) field. A moving image advertisement using a large screen is expected to be an advanced advertising medium because it has a large amount of information and can be operated in various ways such as time lending.

Next, a description will be given of a conventional example in which a video display device or a scented video display device is used for advertisement and problems.

Japanese Patent Application Laid-Open No. 10-10987 discloses a multi-function electronic display that detects a stop of a person and outputs a visual message, an olfactory message, and a voice message for the purpose of attracting customers to a store or the like. It is mainly installed in front of the store to assist users in selecting menus and to issue promotional cards. The scent generator is next to the screen and the scent is diffused by the blower. Moreover, although a human body sensor is used, the sensor is for detecting the presence of a person in front of the display.

Japanese Patent Application Laid-Open No. 2002-015204 discloses an advertisement output device that reads an attribute of a prospective merchandise purchaser from card information and presents an advertisement suitable for the attribute at a POS terminal or the like. Among them, a scent generator can be used as the output device.

Japanese Patent Application Laid-Open No. 2006-292948 discloses a technique for presenting an effective advertisement by generating a scent linked to broadcast commercial video / audio. It is a service for homes that receives advertisements through TV broadcasting.

Japanese Patent Laid-Open No. 2005-173910 discloses a system that links video, sound, and scent for the purpose of creating a healing environment when a person who returns home is welcomed.

As described above, there have been inventions such as providing product selection, healing, etc. by combining video, fragrance, and sound for customers who have stopped by, customers who have entered the store, or people at home. To do. Many of them detect a person's drop-in and use this as a switch to present content.

However, in the field of public information presentation devices such as digital signage, a means for giving interest to not only those who stop by but also passers-by who walks is important. First, ask the user to look at the screen, prompt the user to stop, and then check the details when the user stops. In other words, it is necessary for a passerby to be interested in the video content and to guide it in front of the screen. There are few inventions aimed at improving the attractiveness, inductivity, and drop-in rate.

In addition, in the advertising field targeting unspecified people such as passers-by, there is a problem that it is difficult to present highly-preferred advertisements. For example, content that is preferred by interested people may be annoying to those who are not interested. For this reason, in the public place, conventionally, there has been a tendency to present only contents that are not inconvenienced by people, that is, that are widely accepted by ordinary people. However, there is a problem that cannot introduce detailed products.

Advertisements that detect the presence of a visit and present a product image with a scent are effective, but since the scent is an information medium with a strong preference, a scent generating device that does not disturb the surroundings is desirable in public places .

In response to this requirement, a scent generating device has been proposed that uses the principle of an air cannon and presents the scent as a vortex ring to the user's nose tip in a pinpoint manner. Advanced air flow control technology is a problem because the distance to fly is increased. In addition, there is a problem that the user does not become an olfactory stimulus unless the user sucks the vortex ring of the scent. Furthermore, the scent generator has problems such as taking up space and being obstructive.

JP 10-10987 JP 2002-015204 A JP 2006-292948 A JP-A-2005-173910

The problem to be solved by the present invention is to increase the interest of passers-by, pass by, and improve information transmission dramatically in a public information presentation device using a video display device or a scented video display device. That is. Specifically, it is as follows.

(1) Increase the attractiveness so that passersby are interested in the screen or advertising content. Furthermore, the passerby is guided to the front of the screen.
(2) Presenting advertisement content preferred by passers-by at an appropriate distance. On the other hand, it will not be annoying to passersby who are not interested.
(3) When approaching or stopping by the screen, the scent is presented as if scented from the product image to promote understanding of the content. Presents irritation reliably with less fragrance. Presents a scent that clearly rises, for example, “Pun”, and increases purchase motivation. Keep the scent generator out of sight so it doesn't get in the way.
(4) Focus on content for as long a time as possible to a passerby while traveling and present detailed information.

<Means 1>
The public information presentation apparatus of the present invention will be described with reference to FIGS. 1, 2, 9, 10, and 11.
In an apparatus for detecting an approach of a person and presenting an image or a content having a chemical substance as an element, the content (IMG) whose viewpoint has been converted so as to prompt a visit is presented.

The detection of the approach of the person (Sen, 71 in FIG. 1, FIG. 9, GPS in FIG. 10) is the detection of the position or distance of the person who is approaching the information presentation device, and the viewpoint-converted content The video or the presentation of chemical substances is controlled based on the detection result. In other words, according to the present invention, the content to be presented is interactively changed according to the position or distance of the passerby, thereby increasing the attractiveness and interest, and prompting the user to stop in front of the information presentation device.

For example, as shown in FIGS. 2B and 2C, a motion parallax image whose appearance changes depending on the viewpoint position can be displayed. The video can be generated by perspective projection conversion based on a three-dimensional world model. Alternatively, a multi-viewpoint video can be stored in advance, and the video can be selected and displayed as appropriate based on a person position detection result. When approaching the screen, the appearance changes and it is perceived in three dimensions. In the case of a large screen, another space is perceived with a high sense of presence on the wall of the passage, so that the attractiveness or inductive effect is high.

Moreover, viewpoint conversion includes changing the content of content step by step according to a person's position or distance. When the user is away, a video or scent that can be accepted by many people can be presented, and a specific video or scent of the advertising product can be presented so that the user can stop by as they approach the screen. . That is, according to the viewpoint position, it is possible to switch from highly receptive content to highly palatable content.

As described above, a detailed product introduction or the like is possible for a person who stops by the information presentation apparatus.

<Means 2>
The public information presentation apparatus of the present invention will be described with reference to FIGS. 1, 2, and 11.
In the means 1, the presentation of the chemical substance (fragrance) is based on a person's position or distance detection result, and information is transmitted (subject to advertisement) from a substance having a wide physiological or psychological tolerance. It is characterized by being changed to a substance suitable for the content of the product.

Since fragrance is a luxury item, care must be taken when presenting the fragrance in public. A scent with a wide physiological or psychological tolerance does not bother a passerby and has an action of interest. After approaching, presenting a characteristic scent suitable for product images enhances the sense of reality and deepens the understanding of the content.

The means for detecting the approach of the person includes a person attribute detection (gender, age, hobbies, etc.), and can change the content of the video based on the attribute. In addition, it is possible to use a combination of means for detecting the weather, day of the week, and time of the place where the public information presentation device is installed. With these controls, content understanding is further enhanced.

For example, if the season is a summer evening in a dining area, it encourages people to come from far away with a wide range of tolerance and a refreshing video and scent that is generally preferred, and invites appetite as they approach An image and a scent may be presented, a stoppage may be detected, and a specific store image and scent may be presented.

<Means 3>
The public information presentation apparatus of the present invention will be described with reference to FIGS. 1, 8, 9, and 10.
The means 1 and means 2 use a human approach detection means by transmitting and receiving a signal between the device (10) and the mobile communication terminal (Ue) for the viewpoint conversion presentation of the content. And

As shown in FIG. 8A, the mobile communication terminal side (Ue) has an ultrasonic transmission means (63), and the apparatus side has a plurality of ultrasonic reception means in or around the screen (64). The position of the person can be detected in the coordinate system of the screen from the ultrasonic transmission time measurement. The terminal has communication means and can transmit an ultrasonic signal with a code based on an instruction from the apparatus side.

As shown in FIG. 8 (B), the apparatus side has a directional communication medium transmitting means (63) in the screen or the periphery thereof, and the mobile communication terminal side has the communication medium receiving means and a reply means, The position of the person can be detected from the reply information. As a communication medium, ultrasonic waves, near infrared rays, electromagnetics, and the like can be used. The device side can radiate the communication medium to a predetermined angle range (AR) and detect that a person has entered the range if a reply is received from the mobile communication terminal. Moreover, the position of a person can be detected in the coordinate system of the screen by including the ultrasonic transmission time in the reply information.

As shown in FIG. 8 (C), the mobile communication terminal side (Ue) includes an electromagnetic receiving means (66), and measures its own position by detecting the intensity of the electromagnetic wave (65) transmitted from the apparatus side. Alternatively, the position information can be estimated and transmitted to the device side.

Moreover, as shown in FIG. 10, you may transmit the positional information provided from GPS to a public information presentation apparatus using the portable communication terminal (Ue) which has GPS.

As described above, since the position of a person can be accurately identified using a mobile communication terminal, the motion parallax display, the image according to the position information, the presentation of the scent, the guidance of the person to the front of the screen, etc. are realized with high accuracy it can.

<Means 4>
The public information presentation apparatus of the present invention will be described with reference to FIGS. 1, 2, 9, 10, and 11.
In a device that detects the approach of a person and presents an image or content containing a chemical substance as an element, the mobile communication terminal (Ue) owned by the person can request information or accept or not accept information. The device (10) transmits a signal, and the content presentation is controlled based on the signal and the position information of the mobile communication terminal (SG2).

The portable communication terminal has a desired information list and can transmit the list as an information request. The device can select and present relevant information (such as an advertisement) from the list. Also, the terminal can check the information content transmitted from the device against the information list and transmit an information acceptance or non-acceptance signal.

For example, as shown in FIG. 2, if the mobile communication terminal owner is away when presenting an advertisement for a product (coffee) based on an information request, the advertisement is displayed by a person other than the mobile communication terminal owner. In order to touch the eyes of the product, contents that are easy to accept even for a general person such as a product concept are presented (IMG1 to IMG3), and the details of the product are satisfied so that the request of the mobile communication terminal is met as the owner of the mobile communication terminal approaches. Content can be presented (IMG4 to IMG5).

That is, the relevant information can be appropriately presented to a person who has requested information while switching from rough general information to detailed information according to the distance.

Moreover, if the mobile communication terminal owner is away, there is little harm even if information presentation of the non-acceptable product is performed. Therefore, the advertisement information presentation device can control to switch to another content when receiving the non-acceptance signal from the mobile communication terminal and detecting that the terminal owner is approaching. Thereby, a person who is not interested does not become unpleasant with an advertisement or the like. For example, an advertisement or the like that adversely affects adolescents can be controlled to switch to another content when the person approaches.

In electronic street advertising (digital signage), it is necessary to balance personal taste and public consideration. Care must be taken especially when using a medium with a strong preference such as fragrance. By giving the information selection right to the mobile communication terminal side, it is possible to present an appropriate advertisement or the like to the person who owns the mobile communication terminal without causing trouble to the surrounding people.

Using the location information of the mobile communication terminal, personal information can be presented to the public information presentation device in the passage of the terminal owner. Only when the person passes in front of the public information presentation apparatus, the apparatus is for the person. The same applies to other passers-by. That is, the information content can be changed according to a passerby like a chameleon. From a remote location, a message can be sent to the owner of the mobile communication terminal via the public information presentation device.

<Means 5>
The public information presentation apparatus of the present invention will be described with reference to FIGS. 1 to 5 and 9 to 11.
In an apparatus that detects the approach of a person and presents an image or content including a chemical substance as an element, the chemical substance presentation apparatus (01B) is provided inside or behind the display apparatus (10). The chemical substance is presented to the person from the screen.

The chemical substance presentation device can present a chemical substance to a human nose using the principle of an air cannon.
The approach of the person is detected, the person is guided to a predetermined place on the screen, and the scent can be presented from the vicinity of the screen on which the scent generation target is displayed. As shown in FIGS. 2 and 11, the means for guiding the person to a predetermined place on the screen is possible by video or voice message.

<Means 6>
The public information presentation apparatus of the present invention will be described in association with FIG. 2 and FIG.
In an apparatus for detecting the approach of a person and presenting an image or content having a chemical substance as an element, the apparatus is characterized in that a chemical substance is presented by detecting or estimating an inhalation timing of a person who has stopped by.

The person who stops by the video or voice message can be encouraged to breathe or smell. Alternatively, a time model from when the message is presented until the inspiration is generated may be prepared in advance, and inhalation may be estimated or predicted based on the model to present the scent.

For example, when the message “I will present the scent from the product video in 3 seconds from now” is sent, the person in front of the display device is in a posture waiting for the scent called olfactory expectation. There are many cases where breathing is arranged and the nose is brought close to the product image after 3 seconds and inhaled. If this timing is estimated or predicted and a fragrance is presented, the sense of smell can be surely stimulated with a small amount of fragrance.

The upper body of the person in front of the screen may be captured by a camera, the feature of breathing motion may be detected by image processing, and inspiration may be detected or estimated. The action of bringing the nose close to the scented object or the action of expanding the chest can be a feature of the breathing action. In addition, a microphone may be mounted on the screen to detect a person's breathing sound and estimate inspiration.

When a passerby is guided in front of the screen, inhalation is detected or estimated, and a scent is presented from the screen to the nose with a chemical substance display device using the principle of an air cannon, the interaction between the image and the scent is high. Become. In particular, when a chemical substance is presented from the screen to a person approaching the screen, it is very easy to understand the content.

<Means 7>
The public information presentation apparatus of the present invention will be described with reference to FIGS.
A plurality of devices (10-i, i = 1 to 3) are installed in the passage to detect the approach of a person and present video or content containing chemical substances as elements. Content that is continuous between devices is presented.

Content with continuity means content with continuity in video or continuity in chemical substances. For example, it may be a narrative video or a scent presentation. In a long passage, a person sees a wall advertisement while walking or moving on a belt conveyor. Each device can detect the approach of a person, collate the person (SG1, Ue), and present continuous content. Because there is a long distance in airport corridors, it is possible to present rich content.

It is desirable that the information presenting device is provided on a passage wall having a determined direction of traffic such as right-hand traffic or left-hand traffic. The first information presentation device presents only the video and the next information presentation device presents the video and the chemical substance, or the first information presentation device presents only the chemical substance and the next information presentation device Combinations such as presenting images and chemical substances are possible.

After the first information presentation, it is desirable to present the next information at a time to recall the episode memory. The presentation time can be controlled by using human psychological sensory prediction, for example, a phenomenon of expecting an olfactory sensation associated with the video after video presentation (and vice versa).

It is desirable that the plurality of information presentation devices be controlled in combination with a means for detecting a passerby state (congestion status, attributes, etc.), a means for recognizing the device installation environment, or a means for remote monitoring. Continuous content can be presented to the same person or people with the same attributes.

Further, as shown in FIG. 10, it is possible to provide traffic guidance and store guidance using a plurality of digital signage installed on the road. When a person approaches digital signage, guidance for the person who owns the mobile communication terminal is displayed. The guidance can be specific and detailed every time it passes through the digital signage (10-i). When digital signage content is prepared on the store side, customers can be guided to the store.

<Means 8>
The public information presentation apparatus of the present invention will be described with reference to FIGS.
In an apparatus for detecting an approach of a person and presenting an image or content having a chemical substance as an element, information is presented by combining an olfactory stimulus and a skin tactile stimulus (01A, 01B).

The stimulus presentation can be configured by an air cannon. By continuously driving in a short cycle, a wave of atmospheric pressure can be presented as a stimulus, so it is easy to call attention.

It is desirable to detect a person and apply airflow to the face or skin. When a person passes through a group, an air flow may be continuously presented to the group. When the airflow hits the face, the skin tactile sensation is stimulated, which induces actions such as turning around. In addition, the scent is irritating and alerts you. Stopping is encouraged, such as stopping or slowing down walking.

In the public information presenting device of the present invention, the means for detecting the approach of the person passes the state where the person is moving within the predetermined speed range or is in the approaching state, the state where the movement is stopped, or the predetermined It is possible to determine that the speed is below the speed range as a stop, and change the video to be presented or the type of chemical substance.

The public information presentation apparatus of the present invention can receive and store contents from a remote location using communication means. Content can be switched and presented as appropriate based on conditions such as human attributes and time zones. The necessary scents can be stored in advance in the device, and can be presented by switching to synchronize with the video. In addition, content can be presented so as to be linked with the news program of the day. The drop-in rate can be greatly improved.

The public information presentation apparatus of the present invention can be used in conjunction with a remote monitoring system. For example, it is possible to arrange a monitoring camera in the passage, monitor the video at a remote place, and change the contents as appropriate. In the event of an emergency such as a disaster, it can also be used as a guide for blame guidance.

The public information presentation apparatus of the present invention can be used in conjunction with a sales promotion system. For example, information on the location (geography) where the device is installed, the flow of people, the customer base, nearby store data, weather, day of the week, time zone, etc., and the data related to the advertising attention rate or advertising effectiveness The contents can be stored and controlled based on the data. Information about the person's flow, customer base, etc. can be automatically acquired and stored using an image recognition technique by photographing a passage with a camera attached in the vicinity of the apparatus of the present invention.

For example, it is assumed that the information presentation device is installed near a coffee shop in a passage in the Marunouchi area around Tokyo Station. In the morning, there is a flow of office workers, and information such as the ability to sell coffee to wake you up is stored as information about the environment. In this case, if the flow of the office worker is detected and the image and scent of coffee are presented, the advertisement of the coffee shop is obtained. Also, during the return time, the content can be used for flower shop advertisements with flowers.

<Effects of Means 1 and 2>
The content of the information presentation device provided in the passage changes according to the movement of the person, that is, the video or fragrance content changes interactively, so that the attractiveness is high. There is an effect that a person who has shown interest is invited in front of the screen.

In particular, when a motion parallax image is presented by detecting the approach of a person, the image is perceived in three dimensions. During walking, a virtual space different from the actual space is perceived in the wall of the passage, so that the attractiveness and inductivity are remarkable and the drop-in rate is increased.

Moreover, since it can control so that the detailed image | video and fragrance relevant to advertising goods are shown as a person approaches a screen, it is easy to understand goods and the advertising effect is high.

<Effects of means 3 and 4>
By communicating with a portable communication terminal held by a passerby, the position of the passerby can be detected easily and accurately. Therefore, content presentation based on viewpoint conversion can be realized with high accuracy. Specifically, it is possible to display motion parallax with high accuracy, or to guide a person to a predetermined place on the screen and present a scent. Good product understanding and high advertising effectiveness.

A thin large display device and a mobile phone can be combined to present personal advertisements to passers-by approaching the device. The advertisement effect is high because information corresponding to the attribute of the mobile phone owner is automatically presented on the large screen instead of advertising on the small screen of the mobile phone as in the past.

Since the mobile communication terminal can transmit an information request or an information acceptance or non-acceptance signal, a passerby can efficiently obtain only the information he wants when he approaches the device. Moreover, unnecessary information is not pressed. It is possible to present information that balances personal preference and public consideration. This is a concept that was not found in conventional street advertising.

<Effects of Means 5 to 6>
Since the scent can be presented from the screen, when the user approaches the product image, the user can feel as if the product is scented. It has the effect of improving interest in products.

Since a passerby is guided in front of the product image and presents a scent during inhalation, it can be reliably received. This has the effect of deepening interest and understanding of the product. Moreover, since a fragrance is not diffused to the surrounding people, a characteristic fragrance can also be used. For example, it can present a scent of fish dried fish that is not normally available to the public. Since the scent is very small, it will not be a nuisance to those around you. Suitable for advertising various products.

<Effect of means 7>
Since multiple public information presentation devices are installed in the passage and content that is continuous between each device is presented in synchronization with the flow of people, if placed in a long passage, the content is dark for a long time, or It has the effect of presenting complex information. Moreover, it can guide to the target place.

<Effect of means 8>
When a human approach is detected and skin tactile stimulation and olfactory stimulation are presented, the person has the property of seeing (turning around) the direction in which the stimulation comes. Since the video is presented at this timing, the attractiveness to the content is enhanced, and there is an effect of prompting a stop. After that, more detailed product content can be presented, which is highly effective for advertising.

Embodiments of the present invention will be specifically described.

FIG. 1 is a first embodiment of the present invention, and is for public use that is converted from a viewpoint so that advertisement content including an image and a scent as an element is prompted based on the position or distance information of a person. It is an information presentation device. It is assumed to be used in underground shopping areas. Aki is a person approaching the display device or a person who stops in front of the device. The figure shows a state seen from above the passage Road.

The configuration of the apparatus will be described. Reference numeral 10 denotes a display device, and 12 denotes a board-like screen. 01A is a gas discharge device using the principle of an air cannon for discharging a scent toward a predetermined direction of a passage, and is housed in a part of 12. 01B is a gas release device provided inside the display device, and can release fragrance, high-concentration oxygen, mist, pharmaceuticals, negative ions, or a mixture thereof from a screen toward a person.

In 01A, 08 is an air tank, 09 is an instantaneous pressure generating mechanism, 20 is a bimorph type piezoelectric element, 06 is a gun barrel, 02i (i = a, b) is a scent discharge tube, and 36A is a scent supply unit. Various fragrances can be mixed with the air Air and released as an annular vortex mass (vortex ring) 04. Details will be described later with reference to FIG.

In 01B, the tip is composed of a number of scent discharge tubes 02i (i = a, b, c, d), which are provided on the board-like screen 12 as shown in the enlarged view of FIG. 1 (B). It is attached so as to be inserted into the hole 02. Here, the hole 02 is provided between the light emitting display elements 11 (Pix) constituting the pixel. A large number of scent discharge tubes are bundled to form a virtual barrel 05. From 05, the scented vortex ring 04 is released. Details will be described later with reference to FIG.

A fog generator Mist can be attached to the air tank 08 of 10B. By generating a mist with Mist and passing it through the scent discharge tube 02i, a fragrance can be mixed with the mist and discharged. Since the discharged vortex ring becomes heavier than that of gas, the vortex ring flies stably.

In addition, since the mass has an appropriate humidity, the olfactory characteristics are improved. The mist can be cooled with a cooler Cooler, heated with an electric heater Heater, and put into an air tank. Therefore, a fragrance can be mixed and released in cold gas and warm gas.

Reference numeral 60 denotes an acoustic presentation device using an ultrasonic speaker, and 62 denotes a pan head that rotates 60 and a direction control mechanism. SDBeam indicates a super-directional sound wave. 61 is a small speaker provided on the back surface of 12. A voice message can be presented to the user. The sound wave is emitted from the hole 02 provided on the screen.

Reference numeral 71 denotes an apparatus for extracting feature points of a person provided in 12, a near-infrared light projector 76, a camera 72 that captures reflected light of the light projector, and an image processing device not shown in FIG. Consists of. Although only two 76 are shown in the figure, a plurality of them can be arranged in a circle around the optical axis of the camera lens so as to surround the optical axis. 71 can extract facial feature points, eyeballs, and the like.

The extraction of eyeball feature points will be described. The eyeball has the property that when a parallel light beam is incident from the pupil, the light is imaged in the retina and part of the light is scattered and returned to the incident direction. In other words, there is a property of retroreflecting. Therefore, when 76 is used to irradiate near infrared light toward a person standing in front of the display device and the retroreflected light is captured by the camera 72 disposed in the vicinity of the near infrared light source, the pupil portion is more than the background portion. Is also taken brightly. The pupil region can be extracted by simple image processing. In the present invention, the retroreflected light is efficiently captured by a configuration in which the light source 76 and the camera 72 are arranged close to each other between the pixels 11 (Pix) of the display device.

In FIG. 1A, since two 71 are provided on both sides of the gas release device 01B, the position of both eyes of a person standing in front of the display device can be accurately obtained by stereo image measurement. it can. In the figure, only two 71 are shown, but more may be provided. The larger the number, the wider the measurement range and the measurement accuracy can be improved. If the positions of both eyes are known, it is possible to estimate the position of the head and the position of the nose.

When a pupil image of the eye is photographed using a near infrared illumination device, a corneal reflection image can be photographed at the same time. A cornea reflection image is a virtual image created by light reflected by a spherical cornea. Since the spatial position of the pupil and the relative position of the pupil and the cornea reflection image can be measured, the line of sight can be measured from these pieces of information. An algorithm for this purpose is disclosed in, for example, Japanese Patent Laid-Open No. 02-224737 by the present inventors and can be used in the present invention. The above-described extraction of the pupil or corneal reflection image can be realized by relatively simple image processing.

Furthermore, the shape of the face, eyes, nose, ears, etc. can be recognized by using complicated image processing. By using image recognition technology, attributes such as the number of people approaching the display device, gender, and age group can be detected in detail.

A device for detecting the position of a passerby in order to guide a passer-by Aki in front of the display device 10, present an image of interest to the passer-by, and present a scent as if smelling from the video. The coordinate system of the display device, the coordinate system of the display device, and the coordinate system of the olfactory presentation device must be mutually convertible. This is because it is necessary to present an image to the detected person and release the scent. When these devices are installed separately, the calibration for making the coordinate system convertible is usually quite complicated and tedious.

However, in the present invention, the plurality of feature point extraction devices 71 and the gas discharge device 01B for stereo image measurement are incorporated in the display device 10. In other words, since the positions of these devices can be fixed at the time of manufacture, calibration is unnecessary or can be greatly simplified.

Sen is a passer-by detection device, and includes an infrared sensor, an ultrasonic sensor, and the like provided on the ceiling. For example, in the case of an infrared sensor, infrared light is irradiated downward from the passage ceiling and the reflected light is detected by a phototransistor or the like. If there is an object between the ceiling and the floor, the reflected light is detected. When a passerby passes under the sensor, the head is detected. Since the distance from the ceiling to the head can also be measured, it is possible to distinguish between passersby adults and children to some extent. If a plurality of infrared sensors are arranged in the direction of travel of the passage and the direction crossing the passage, the location of the passerby can be measured in real time.

In FIG. 1, Sen is installed in a grid pattern on the ceiling. Since the ceiling and the wall on which the display device is provided are connected, mutual conversion calibration of the passer's position detection coordinate system by Sen, the coordinate system of the display device, and the coordinate system of the gas release device may be performed once.

As a means for detecting the position and attribute of a passerby, in addition to the above, a method of combining a camera and a mirror described in Japanese Patent Laid-Open No. 09-54894 by the present inventors can also be used. The camera installed on the ceiling is used to photograph the mirror provided obliquely on the ceiling and the passage below it. Since the head and whole body images are taken simultaneously, it is possible to detect the attribute of a person passing through a predetermined position in the passage by image processing.

Ue is a mobile communication terminal owned by a passerby. The terminal can transmit user attribute information, location specifying information, and the like. SG1 is a communication device, and SG2 is an information processing device. The information of Ue is received by SG1, and the attribute and position of the user are detected by SG2. Details will be described later with reference to FIG. As described above, the position and movement of a passerby can be detected by various methods. Of course, some or a combination of these methods can be used.

The video presented on the board-like screen 12 can be changed with the position information of the passer down. A grid ChangeRG in front of 10 indicates a place where an image is switched in order to realize motion vision. Further, ChangeCON indicates a place where the video content is switched.

Next, the operation of the public information presentation apparatus will be described with reference to FIG. 1 and FIG.
FIG. 2 shows how the video is changed in accordance with the movement of the passerby. The reference numerals in FIG. 2 are the same as those in FIG. A solid line Movement indicates a flow line where the passer-by Aki approaches the display device 10. IMGi (i = 1 to 6) indicates a temporal change of the video in each region.

In FIG. 1, when a passerby approaches, this approach is detected by the sensor, and voice information such as “Notice of new product” is presented from the ultrasonic speaker 60, and a new product is displayed on the display device 10. A video about is displayed. Here, if the attribute of the passerby is detected by receiving information from the mobile communication terminal Ue, it is possible to present more detailed information. For example, “Notice of new products that are now popular among young women”.

Since the ultrasonic speaker is highly directional, it is easy to determine the direction when listening to a voice message while walking. It is easy to understand because the sound increases at the moment of crossing the acoustic beam SDBeam and decreases when it crosses. Passers-by can easily turn their face naturally if they know the direction in which the sound comes.

Here, when a scent is presented, interest in that direction increases. In the direction facing the face, a video that attracts interest is presented in a timely manner, so that interest further increases due to the interaction of vision, hearing, and olfaction, and the passerby moves to be attracted to the display screen. This is shown by the flow lines in FIG. The drop-in rate is greatly improved.

In FIG. 1, the scent may be presented first, and then a voice message may be presented. Moreover, you may present a fragrance and an audio | voice simultaneously. It is important to present multiple sensory stimuli within a time period that produces a synergistic effect. The target image is created by presenting scents, audio, and video within seconds of information being integrated within the brain. The subject image is strongly reminiscent of past memories, so interest is rapidly increasing. As a result, the person is attracted to the display device.

It is possible to make a database in advance and store it in the storage device MR as to what kind of fragrance is effective for which kind of person. The attribute information includes gender, age, occupation, etc., and SG2 sends an instruction to 01A or 01B to present a scent that matches the attribute information with reference to the database in MR. be able to.

For example, if the passerby is a woman, a flower image such as a rose or a lily may be displayed to release the scent of the flower. If you are a man, you can display images of the sea and mountains, and release marine and forest scents.

When a passerby is away from the display device, it is desirable to have a scent that is easy for many people to accept. This is because there is a person who does not like the characteristic fragrance with strong taste. As a passerby approaches, it can be automatically changed to a characteristic scent that matches the attribute. The same applies to video.

In addition, the passerby can record a product field of interest in the mobile communication terminal in advance as an information list and transmit the information list to the information presenting apparatus as an information request. The device can receive the list and select and present related advertisements from the list. At this time, the video and the scent associated with the advertisement can be switched as approaching. Moreover, the passerby can also directly send an instruction to present a favorite video or scent to the information presentation device using the mobile communication terminal Ue.

As described above, the scent can be changed from a physiologically or psychologically acceptable substance to a substance suitable for the content of the advertisement. Thereby, it is possible to enhance the sales promotion effect by a characteristic scent for those who approach the screen with interest without causing trouble to those who pass without approaching the screen.

The advertisement presented by the information presenting apparatus side includes those that passers want to accept and those that want to reject (non-accepting). Therefore, the mobile communication terminal has an information acceptance / non-acceptance list, obtains advertisement information transmitted from the device side by communication means, collates with the information acceptance / non-acceptance list, accepts or does not accept The signal can be notified to the information presentation device side.

If it is an acceptance signal, the device will present the details of the advertisement when the passerby approaches, and if it is a non-acceptance signal, the device will change the advertisement to another before the passerby approaches. Can be controlled.

Next, the operation after the passerby is drawn to the display device in FIG. 1 will be described.
When the passer-by Aki comes to the video switching boundary ChangeRG1 provided in front of the display device, it switches to the motion video. That is, since the position of the passerby is known by the detection device Sen or the like, an image that can be seen from the position can be generated and displayed. The computer has a three-dimensional space model based on computer graphics (CG), and an image when the three-dimensional space model is viewed from the detected viewpoint position is generated by a perspective projection transformation method and displayed on the screen. By this method, it is possible to realize motion vision by changing the image every time the passerby's position crosses the boundary.

Motion display using CG may not have high image quality with current technology. Therefore, FIG. 2 shows a case where a live-action video is used for the purpose of using an advertisement. FIG. 4B shows images presented in the areas IMG1, IMG2, and IMG3. Each moving image can be prepared in advance by simultaneously photographing the same real space from a location corresponding to the viewpoint of the area. Each image is slightly shifted by the amount of parallax. That is, it is possible to prepare as many live-action video images as the number of viewpoints of motion vision. Alternatively, a plurality of viewpoint videos can be reconstructed and prepared by image processing based on videos shot simultaneously from a relatively small number of places.

These videos are synchronously played back by a multi-channel video playback device corresponding to the number of viewpoints. In practice, this can be realized by storing multi-channel video in a memory and scanning in the time axis direction. As the passerby moves, the video from the viewpoint may be read from the memory and presented. For example, in FIG. 2B, at the timing when the movement moves in a rectangular area, the moving vision can be realized by switching the video as indicated by a thick arrow from IMG1 to IMG2 and from IMG2 to IMG3.

Regardless of whether CG or a live-action image is used, a three-dimensional perception can be obtained by realizing a motion vision, so that a sense of reality and immersion are enhanced. In addition, it is highly attractive, attracts the eyes naturally, and has the effect of prompting a stop. Three subjects, still images, moving images, and motion images, investigated the swinging rate of people passing in front of the large screen with five subjects. Compared to still images, moving images were doubled, and motion images were 3 It was more than twice. The effect is obvious. In the introspection report, there are many opinions that, when walking, the space suddenly expanded in the wall and attracted interest. The more you are interested, the more you stop by.

As the number of viewpoints increases, smooth motion vision is realized, but it is effective even when the number of viewpoints is small and some video skips remain.

Motion visual images are often used in the virtual reality field such as games and simulations, but in public information presentation device fields such as advertisements, there is no example used for the purpose of enhancing the attractiveness and encouraging the visit.

A voice message may be used to further encourage a visit. FIG. 2 shows a case where the user is guided to the center of the display device by a message “Please come closer. I will explain in detail”. A scent discharge device 01B is provided at the center, which is the specific position. It should be noted that the message is an example, and it is natural that the specific position where 01B is provided may be specified and guided.

In addition, when a person approaches 01B in the center of the screen, the content of the video can be made more specific to increase interest and encourage a visit. In FIG. 2, IMG1, IMG2, and IMG3 on the outside of ChangeCON show a healing image of relaxing drinking coffee, and IMG4, IMG5, and IMG6 on the inside show an image of coffee itself. Moreover, the rectangular region of Change RG2 is smaller than Change RG1, and the accuracy of motion vision is improved.

When a person stops by the center of the screen, a fresh coffee image is presented, and a voice message “The scent of the new coffee will be delivered in 3 seconds” is played. When a person sees a video of coffee and hears a voice message, he is ready to wait for the scent called olfactory expectation. There are many cases where breathing is arranged and the nose is brought close to a product image after a predetermined time (for example, 3 seconds) and then inhaled. The scent discharge device 01B can predict the time and present the scent of coffee. Since the scent is presented from the video at an appropriate timing by guiding (or instructing) the nose to approach the video, the certainty of the olfactory presentation is extremely high.

After the voice message, a breathing interval model can be prepared in advance by subject test or the like as to when a person inhales. In FIG. 1, the model is stored in the memory MR, and the information processing apparatus SG2 can control to apply the model to estimate inspiration and present a scent.

In addition, a voice message may be presented so as to count down to “3, 2, 1”, and the intake may be predicted or estimated with high accuracy and the scent may be presented. In addition, in order to instruct | indicate respiration, it cannot be overemphasized by the image | video or the character, or these combination other than the method using the said audio | voice.

In addition, a directional microphone may be provided inside the display device to collect the nasal breath of the person watching the video and estimate the inspiration. The breathing sound is generally large in expiration and inhalation is small. Therefore, an expiration sound can be detected and inspiration can be estimated by applying an average breathing interval model. This method is described in detail in Japanese Patent Application No. 2006-347036 by the present inventors and can be used.

The scent discharge device using the principle of the air cannon is presented on the other hand, because it can present the scent in a spatially and temporally pinpoint manner, so that there is little waste of fragrance and there is no inconvenience to surrounding people. Since the amount of fragrance is small, the scent may not be perceived unless a person is in an inhaled state. However, in the present invention, as described above, the air cannon-type scent generating device is provided in the screen to estimate the breathing or to indicate the scent to compensate for the disadvantages of the conventional device. , You can take advantage of it.

In FIG. 1, since the camera 72 is provided in the screen 12, the face can be caught in front. It is easy to determine a display target that a person is watching with interest by detecting the above-described line-of-sight detection, face orientation detection, blinking, and the like. Therefore, it is possible to estimate the display target being watched and the degree of interest, and control the type of fragrance and the presentation timing.

The gas that can be released from 01B may be a cold wind or a warm wind. Release of such a gas can increase interest by tactile stimulation. For example, in a hot summer underground shopping street, everyone is unintentionally stopped when a refreshing forest image, forest scent, and cold breeze are presented. Also, when high-concentration oxygen is released along with refreshing images during times when you get tired of work in office passages, people who want to recover from fatigue increase. Olfactory and skin tactile stimuli tend to remain in memory due to sensory integration and have a high advertising effect.

Next, the gas discharge device 01B used in FIG. 1 will be described in detail. FIG. 3A is a partial front view of 01B and a cross-sectional view. FIG. 4 is a front view of 01B. The reference numerals are the same as those in FIG.

The light emitting display element 11 includes, for example, an LED, a plasma discharge tube, an EL element (including an organic EL), and the like. Each forms a pixel (Pix). Reference numeral 12 denotes a board-like screen on which 11 is mounted. A wiring for driving 11 is provided inside 12. 11 is connected to the wiring. The board material can be glass, plastic (molded resin), carbon material, FRP, light metal, wood, or a combination thereof.

Reference numeral 13 denotes an eleven drive control device. The light amount of the light emitting display elements 11 arranged in a matrix is adjusted by the device, and an image is displayed on the screen 12.

The scent discharge tube 02i (i = a, b, c, d) is inserted into the hole 02 provided in the board. 02i are bundled to form a virtual gun barrel 05. Here, when the aperture ratio YAS of 05 is defined as a numerical value obtained by dividing the sum of the aperture areas of each hole (ΣOpen02i) by the area Area05 of 05, the gas emitted from 05 is rectified when YAS is 10% or more. If YAS is set to 20% or more, 05 can release gas as a mass.

The hole 02 provided on the screen is inconspicuous and needs to be cleanable when clogging occurs. The hole diameter is preferably 0.1 mm or more and a viewing angle of 0.5 degrees or less at the shortest viewing distance, or 0.25 degrees or less at a normal viewing distance. The public information presentation apparatus may be viewed from a distance of several tens of meters to 1 m or less. The maximum diameter of the hole varies depending on the installation environment of the apparatus, but a few mm to several cm is appropriate.

Next, the scent supply unit 30 that supplies scent to the scent discharge tube 02i (i = a, b, c, d) will be described. Reference numeral 32 denotes a part of the pipe line starting from 02i, and a plurality of holes Hol are provided in the pipe wall. Reference numeral 31 denotes a perfume accumulation mechanism, which can use a network structure material, a porous material, or the like. Liquid fragrances, gel fragrances, etc. can be stored in the mechanism. a is a fragrance | flavor. The liquid is retained inside the microstructure by capillary action. The perforated pipe line 32 serves as a cover plate for holding the perfume accumulating mechanism 31. The fragrance | flavor of 31 vaporizes and is supplied to the pipe line 02a from the hole Hol.

About the fragrance | flavor storage mechanism 31, the structure of Unexamined-Japanese-Patent No. 2004-159875 by the present inventors can be used. Further, as 31, a gelled fragrance, a solid fragrance, or a microcapsule material can be used. In this case, since the fragrance does not leak, the fragrance can be processed into a cylindrical shape and mounted.

HT is an electric heater, and 15 is a device that controls HT, and can accelerate the vaporization of the fragrance. CN is a connector for connecting HT and 15. In this figure, 15 is connected only to the CN for 02d, but naturally it is also connected to the CN of another pipe. When HT is operated and 31 is heated, vaporization of the fragrance is promoted and a large amount of fragrance is supplied to the pipeline.

Reference numeral 33 denotes an air flow control plate for opening and closing the scent supply hole Hol of 32, and is formed of a magnetic body having a cylinder similar to 32. An air hole Hol is provided in 33 so as to face the 32 holes Hol. In the 02a scent supply unit 30, 33 is normally urged to the left by the spring 35. In this state, the positions of the holes 32 and 33 are off and the holes are closed. Therefore, no scent is supplied into the tube.

By inserting 32 Ends into 41, the airflow control plate 33 is connected to the electromagnetic drive mechanism 39 and becomes operable. Reference numeral 14 denotes a drive control device. When the electromagnet 40 is energized, the magnetic flux passes through 41 and reaches 33. When 33 is slightly pulled to the right, the holes Hol of 32 and 33 face each other and allow gas to pass therethrough. 02b shows this state. The scent evaporated in 31 passes through the hole and is supplied into the scent discharge tube 02b.

Since the scent discharge tube 02i can be removed, maintenance is easy. Further, since one kind of fragrance is accumulated in one tube and the vaporized fragrance passes only through the tube, the fragrance of one tube is unlikely to contaminate another tube. Even when used for a long time, the dirt is limited, and maintenance is easy. Since the fragrance is rarely mixed inside the apparatus, the scent change is clear. Since thin fragrance discharge tubes are used in an integrated manner, many fragrances can be switched at high speed, and perfumes can be prepared and released.

The instantaneous atmospheric pressure generation mechanism 09 includes a bimorph piezoelectric element 20. 21 is a metal plate and 22 is a piezoelectric plate. Reference numeral 16 denotes a voltage control device, which controls the voltage applied to 22. When a voltage is applied to 22, the 22 expands and contracts in the plate surface direction depending on the polarity of the applied voltage. In a state where 22 is contracted, 20 is curved inward as indicated by a broken line in FIG. 2 and compresses the gas in the air tank 08. The air in 08 is sent to the scent discharge tube 02i. On the other hand, in a state where 22 is extended, 20 is curved outward to lower the atmospheric pressure in 08 and take in air. That is, the atmospheric pressure in the air tank 08 can be controlled by 16. In this embodiment, the bimorph piezoelectric element 20 is used as the instantaneous atmospheric pressure generation mechanism 09, but an electromagnetic air compression mechanism can also be used.

Next, the operation of 01B will be described. A predetermined fragrance a, b, c, d is accumulated in the fragrance accumulation mechanism 31 of the scent discharge tube 02i. 39i slides 33 to the right to supply the scent to the pipe line 02i, and then puts 07 into a compressed state. Air Air is sent to each 02i, and the scent is released from the tip of 02i.

The important point here is that in 02i (i = a, b, c, d), there are tubes that release fragrance and tubes that release only air depending on the operation of 39i. Is to be released. Therefore, when there is a scent and when there is no scent, the amount of gas released does not change depending on the type of scent. The aperture ratio is always high, and a vortex ring can be made stably. FIG. 3A shows a state in which air Air is released from 02a and 02c and scent Frg is released from 02b and 02d. That is, a mixed gas of the fragrances a and b is released.

3B and 3C show the operation pattern of the compression plate. (B) maintains the rotation at the time of discharge to the gas mass by instantaneously increasing the air pressure of the air tank 08, releasing the gas as a vortex ring, and reducing the pressure after the gas mass starts flying. It is something to be made. A mass of gas can fly far away.

FIG. 3 (C) shows an increase in the pressure of the gas tank 08 by instantaneously increasing the pressure of the air tank 08, releasing the gas in a lump, and instantaneously reducing the pressure before the gas lump starts to fly. The vortex rotation direction is changed for flight. In the method shown in FIG.

FIG. 5 shows another embodiment of the gas discharge device 01B. FIG. 4A is a front view, and FIG. The light emitting display element 11 includes a light emitter 18 and a lens 19. 18 can be an LED, a discharge tube, an EL element, or the like. 19 can be made of transparent resin, glass or the like, and enlarges the light emitter 18.

A large number of air holes 02 are provided between the lenses 19. In 02, a scent discharge tube 02i (i = a, b, c) is inserted, and an atmospheric pressure generating means 07 is provided on the right side of 02i. 02i and 07 constitute a scent discharge device 01B. 36A is a scent supply part which provides a hole in the side surface of the tube 02a and supplies the scent Frg from the outside. Reference numeral 33 denotes a tubular airflow control plate that controls the supply or blocking of fragrance by moving it to the left and right. Reference numeral 39i (i = a, b, c) denotes 33 electromagnetic drive mechanisms.

The air pressure generation means 07 is constituted by a blower 97. When the impeller 47 is rotated by the motor 58, the air Air is taken in from the right side of the air tank 08, the inside of the air 08 is pressurized, the Air flows into 02i as indicated by a one-dot chain line arrow, and is discharged from the front surface of the screen 12. The In the same figure, three fragrance supply parts 36A operate | move, each fragrance Frg is supplied to 02i, and it has shown a mode that three types of gas are mixed after discharge | release. The opening area YAS of 02i with respect to the area of 05 is desirably 10% or more.

In this embodiment, an air hole 02 is provided behind the lens 19. Since the light from the light emitter 18 is irradiated forward by the lens, the light rarely irradiates the hole. The hole is so dark that it is hardly perceived.

Next, the gas discharge device 01A used in FIG. 1 will be described in detail. FIG. 6A is a front view and a cross-sectional view of 01A. The reference numerals are the same as those in FIG.

This is a scent preparation and discharge device (gas discharge device 01) in which a plurality of scent discharge tubes (02i) are arranged on the inner periphery (inner surroundings of cylinder) of a gun tube 06 and a space is provided in the center of the gun tube. The gun tube 06 is formed integrally with the scent discharge tube 02i, and is attached so as to fit into the air tank 08 of the pressurizing means 07. FIG. 6B shows the distal end portion of the gun barrel 06. End indicates a terminal insertion part.

36A is a scent supply part which supplies a fragrance | flavor in the scent discharge | release pipe | tube from the outside. 36A provided in the scent discharge tube 02a indicates a non-operating state, and 36A provided in 02b indicates an operating state. When the scent is to be released, the scent supply part 36A of the predetermined scent discharge pipe 02i is put into an operating state immediately before the release, and the air compression mechanism 09 is operated. The flow of gas is unidirectional in front of the barrel as shown by the alternate long and short dash line, and since there is little mixing with residual gas, the presentation of scent and switching are very clear. Moreover, when blending and releasing fragrance, the blending accuracy is high.

In FIG. 6A, the gun tube 06 is smoothly thinned from the end portion to the tip portion. When the gun barrel end is pressurized, the air flows along the gun barrel and becomes faster as it advances to the tip, as indicated by the alternate long and short dash line Air. The center of the cannon is the fastest and the periphery is slow. For this reason, a beautiful annular vortex is generated. The angle θ of the gun barrel tip shown in FIG. 6C is preferably in the range of 0 to 60 degrees.

Although the scent supply pipe 02i is provided along the inner periphery of the cannon, since the air is difficult to enter when the end portion is thin, an air collecting mechanism 46 is provided so that the end portion can easily enter air. A conical cylinder 46 can be selected in size in consideration of the balance of atmospheric pressure.

In order to make a vortex ring, the area through which air passes at the tip of the cannon is an important parameter, and the total of the open area Open06 of the cannon and the open area Open02i of the gas discharge pipe with respect to the inner peripheral area Area06 of the cannon The ratio YAS is preferably 20% or more. In the case of the configuration shown in the figure, about 90% of YAS is obtained.

As shown in FIG. 6, the gun barrel 06 is configured to be removable from 07, and the fragrance passing through the scent discharge tube 02i leaks into the gun tube 06, in other tubes, or into the air tank 08. Therefore, handling and maintenance are easy. A fog generator Mist is connected to the air tank 08, and heated mist and cooled mist can be discharged.

FIG. 6D shows another embodiment of the instantaneous atmospheric pressure generating mechanism 09, which has a configuration using a servo motor 55. FIG. 56 is a link mechanism, 51 is a compression plate, and 54 is a bellows mechanism. DV indicates the operation of the compression plate. By using a servo motor, position control and speed control of the compression plate are possible. For example, control can be performed as shown in FIGS.

FIGS. 7A and 7B are cross sections of another example of the mechanism for supplying scent to the scent discharge tube 02i (i = a, b...), Which is an alternative to 30A in FIG. 3 or 36A in FIG. It is.

The structure and operation of FIG. 06 is a part of the barrel, 02i is provided in the cylinder, and an ultrasonic transducer 92 is provided in the hole of the cylinder wall of 02i. Reference numeral 96 denotes a holding mechanism 92. LiqKaori is a liquid fragrance and is transported to the vicinity of 92 by a small electric pump Pon and a transport pipe 38. A concave plate 92 vibrates at 1 MHz or more in the plate thickness direction to atomize the liquid. Since it is concave, the ultrasonic waves are focused, and the liquid is efficiently atomized at the focusing point. When driven at a high frequency of 2 MHz or higher, the liquid becomes particles (mist) of about 1 micron and is discharged into 02i.

49 is an airflow valve and is normally closed. In a closed state, a mist-like scent mis is supplied into 02i, and then 49 is opened and the air compression mechanism is operated to release mis. 49 may be opened by a drive mechanism not shown in the figure, or may be automatically opened by applying atmospheric pressure. 49 prevents the scent from flowing back into the air tank 08. Therefore, switching to a fragrance is certain.

The structure and operation of FIG. 7B will be described. Instead of the 92, a piezoelectric atomizing head 93 is used. 93 is configured by a pressure mechanism using a small liquid container 94 and a piezoelectric element Piezo that compresses the liquid in the container. As shown in the figure, when Piezo is deformed and pressure is applied to the liquid, the liquid blows out as a mist mist from a thin nozzle. ma represents fine particles containing the fragrance a. The release of mis is the same as described above.

FIG. 8 shows another means for detecting the position of the person who owns the mobile communication terminal Ue in the embodiment of FIG. In FIG. 8A, Ue has an ultrasonic transmission means 63, and the information presentation apparatus side has ultrasonic reception means 64-1 and 64-2 in or around the screen, and the ultrasonic transmission time. It is an example which detects the position of Ue from measurement.

The operation will be described. The display device 10 instructs the mobile communication terminal Ue to transmit ultrasonic waves using the communication unit SG1. When Ue receives the instruction, Ue immediately transmits an ultrasonic wave with a code on it. 64-1 and 64-2 receive the code. Here, since the ultrasonic wave propagates in the air at the speed of sound, the spheres Cir-1 and Cir-2 having a predetermined distance calculated from the transmission time can be set. The position can be detected by calculating the point where the spherical surfaces intersect. This figure shows a two-dimensional case, but if three 64 are used, the three-dimensional position can be known. Thus, the approach of a person can be detected by communication between the information presentation apparatus side and the portable communication terminal.

In FIG. 8B, means 63-i (i = 1 to 3) for transmitting ultrasonic waves in a predetermined direction is provided on the back side (in the screen) or the periphery of the display device 10 to receive the ultrasonic waves of Ue. This is an example of detecting the position of Ue by receiving and returning the ultrasonic wave by means 64.

The operation will be described. 63-1 emits an ultrasonic beam in a predetermined angle range (AR) on the left side. The beam is given a code. When Ue enters the beam, Ue reads the code, and returns the code to the information presentation apparatus side by communication means using electromagnetic waves. Thereby, the information presentation apparatus side can detect that a person has entered the beam.

In addition, the Ue side can calculate the distance from the delay of the ultrasonic code arrival time by notifying Ue in advance of the timing of emitting the ultrasonic beam from 63-1 by using electromagnetic waves. The position of Ue can be detected from the direction of the ultrasonic beam and the distance. Although the figure shows a case where ultrasonic waves are radiated in three directions from 63, the position can be detected accurately if ultrasonic waves are radiated in more directions.

An ultrasonic speaker can be used as the ultrasonic wave transmitting means. In the non-audible sound mode, an ultrasonic signal is radiated to a predetermined range of the passage, and when there is a reply from the signal, it is detected that a person has entered the area and a message can be presented in the audible sound mode. Presenting a voice message that produces an olfactory expectation increases the effect of presenting a scent when approaching. It is possible to present the message within a range of 5 m or more and 20 m or less from the display device on the sidewalk, and to present an advertisement content using video or fragrance when approaching the screen.

In FIG. 8C, an electromagnetic transmission means 65 is provided on the information presentation apparatus side (near the display apparatus 10), Ue has an electromagnetic reception means 66, detects the electromagnetic strength, and measures its own position. It is an example which transmits to the information presentation apparatus side. By using a coil for transmitting electromagnetic waves in three orthogonal directions as 65, the position on the Ue side can be recognized by one coil. If a triaxial coil is also used on the Ue side, the position and orientation of Ue can be detected simultaneously.

In any of FIG. 8, the position of a person can be detected in the coordinate system of the display device 10. Therefore, based on the position of the person, motion parallax display, video according to the position information, presentation of a scent, or guidance of the person to the front of the screen can be realized with high accuracy.

FIG. 9 shows a second embodiment of the present invention, in which a plurality of devices for detecting the approach of a person and presenting advertisement content having an image and a scent as elements are installed on the pillar surface of the passage. This is a case where continuity content is presented between the devices in synchronization.

In the figure, 57 is a pillar of passage, 10-i (i = 1, 2,...) Is a display device having a board-like screen, 61 is a small speaker incorporated in the screen, and 01B is in the screen. 4 is a virtual gun barrel as shown in FIG. 4, and 04 is a scent ball released from the gun barrel.

When a passerby (Aki) comes in front of a pillar in a station or underground mall, the position detection sensor Sen detects the approach, releases a scent from 01B, and presents a voice message from 61. The passerby turns and stops to see the electronic billboard (display device). When the passerby stops, the billboard switches from a still image to a moving image.

For example, when a video of several seconds to several tens of seconds flows when the user stops and a scent suitable for the video is presented at the tip of the nose, the passerby can strongly keep the contents of the advertisement in the memory.

Moreover, when a passerby moves like Movement of the same figure, the information presentation apparatus of each pillar can show a video or the content which has continuity in fragrance. When the passerby has the portable communication terminal Ue that can detect the position, since the same person can be collated in front of each pillar, content with high content can be presented while maintaining continuity accurately. When used on a long sidewalk, the advertising effect is great.

In addition, continuity content is particularly suitable for passages where the direction of travel is determined such as on the right side and left side in large underground malls and airports. When using multiple information presentation devices, first present only the video that expects the olfactory sense (directing the olfactory expectation), and the next is to give a strong impression when meeting the expectation by presenting the video with a scent. The advertisement effect is high because it remains.

In addition, when the first information presentation device is used to recall the past episode memories of the passers-by and a predetermined time is given, and further detailed information is presented by the next information presentation device, the impression remains strong and effective. Various combinations of sensory stimuli used in a plurality of information presentation devices are possible.

Many surveillance cameras are installed in underground shopping malls. It is also possible to link with the information system. The public information presentation device may be remotely controlled using the traffic situation of the passerby and the statistical information of the attribute. For example, when there are many young female customers and the situation can be confirmed with a surveillance camera, content suitable for young women can be presented.

FIG. 10 shows a third embodiment of the present invention, in which a plurality of signboard-type public information presentation devices (digital signage) are provided on a road, and a store introduces and guides passersby. is there. The passerby moves along the sidewalk Road from the front to the direction of Movement. Ue is a mobile communication terminal with GPS and can acquire position information. Further, the owner Aki of Ue can register his / her favorite advertisement field or the like as his / her attribute in the storage device of Ue. SG1 is a communication device, and SG2 is an information processing device. SG2 can control SG1 and 10-1.

This figure is an example when Aki likes coffee and a coffee shop by the road wants to guide customers. When Aki approaches the digital signage 10-1, 10-1 communicates with Ue, and acquires the location of Ue and Aki's favorite advertising field. Here, when Ue is within a predetermined distance and there is an advertisement content of a suitable coffee shop from the above-mentioned favorite advertisement field, 10-1 sends information to urge Aki to stop by.

The video presented will be a refreshing content that will appeal to coffee and be acceptable to many people. As noted, viewpoint conversion display is desirable. In other words, the video content can be changed according to motion parallax display or distance. Further, a voice message may be transmitted through the ultrasonic speaker 60. In the initial information presentation, Aki's interest is not yet known, so it is desirable to have an advertisement content that is as resistant as possible and easy to accept.

If Aki goes ahead while paying attention to 10-1, it approaches the next digital signage 10-2. 10-2 takes over the attribute information acquired from Ue and the advertisement content information presented by 10-1 from 10-1. 10-2 detects that Ue is approaching, and presents information on the coffee shop related to the advertisement content presented in 10-1 and the congestion status of the shop as video or audio information. Note that the information to be presented to 10-i can be created as set information by a coffee shop to be advertised, and registered in the means for controlling 10-i in conjunction.

Aki is interested in 10-1, and recalls episode memory related to coffee, so it is easier to accept information about the coffee shop when approaching 10-2. Therefore, it is easy to recognize information such as map information and congestion status, and to judge entry. For example, “There is a coffee shop near here and the atmosphere looks good.”

Aki has the option to stop by at a coffee shop, and when he goes on, he approaches the digital signage 10-3 in front of the coffee shop. If you stop by 10-3, you can present a characteristic video of the store or the scent of coffee. Because I am interested in drinking coffee, I am naturally guided to the store.

In this way, by placing multiple digital signage on the travel route of passers-by and interlocking them, and changing from widely accepted advertising information to characteristic advertising information, we naturally have an interest in the product without a sense of incongruity. Can be made.

Conventionally, there is a navigation system such as a mobile phone, but information to be presented with a small screen is also limited. In the present invention, since a large screen image is presented, the attractiveness is high. In addition, the contents automatically change and the scent can be presented, making it easy to understand. Although FIG. 10 has been described for pedestrians, it is natural that advertisements can be made for people on cars, bicycles, and wheelchairs.

FIG. 11 shows a vending machine capable of presenting a scented video advertisement in the fourth embodiment of the present invention. It shows how to draw people with scents or explain products with scented images to those who have drawn.

The configuration of the apparatus will be described. In FIG. 8A, 82 is a vending machine, 85 is a coin slot, 86 is a coin return slot, 83 is a product selection button, and 88 is a product takeout port. 87 is an electronic fee settlement means such as a prepaid card or a bank card.

Reference numeral 10 denotes a board-like screen display device which includes an LED, a plasma element, and the like. In the figure, three types of coffee product advertisements are presented as indicated by (1), (2), and (3). In the vicinity of each product advertisement video presentation position, a scent discharge device 01B-i (i = 1 to 3) is provided in the screen. On the screen, small holes are provided between the pixels, and the scent is presented from the holes. In the vicinity thereof, a small speaker 61-i and a directional microphone 67-i (i = 1 to 3) are provided in the screen. In the vicinity of the product selection button 83, a button 84-i for selecting a scent is provided.

Reference numeral 71 denotes a feature point extraction apparatus similar to that described in FIG. FIG. 11B shows an enlarged view. A camera lens 74 is provided in the hole 02 of the screen, and a near-infrared light emitting element 77 is provided so as to surround 74. Illuminate at 77 and capture the reflected light at 74. Two sets of 71 are provided to constitute a feature point position measuring apparatus 70 by stereo image measurement. You can measure the position and line of sight of the person who stopped by. Sen is a position detection sensor, and 60 is an ultrasonic speaker. The above parts can be omitted or recombined as appropriate.

Next, the operation of this apparatus will be described. When a passerby approaches, this is detected by Sen, 70, etc., and a directional voice message is presented from 60 to call attention. For example, "How about a fragrant coffee?" The associated scent may be released. People turn around and stop. At this time, the fragrance should be weak and acceptable to many people.

When a person comes in front of the vending machine, the following message is presented from 61 or the like. For example, “If you choose, the characteristic scent of coffee is released 3 seconds after the coffee cup image”. When the person shows interest, he or she presses the scent selection button 84-i to bring the face closer to the coffee cup image. This nasal cavity suction operation can be modeled.

Here, the information processing apparatus not shown in the figure estimates the inspiration by applying the nasal cavity suction operation or the breathing interval model, and releases the coffee scent as a mass from 01 (B) -i. Take control. The advantage of releasing a mass of scent is that the scent can be presented without causing olfactory adaptation. In addition, since the olfactory rise is clear, the impression is strong and the sales promotion effect is high.

A breathing sound of a person whose face is brought close by the directional microphone 67-i may be detected, a breathing interval model may be applied, and the next inspiration may be estimated to present a scent. Moreover, it is also possible to detect the direction and line of sight of a person's face using 70, to estimate a target product of interest, and to continuously present the scent of the product. Customers who are satisfied with the fragrance can easily purchase the product.

In FIG. 11, three types of coffee have been described as an example. Traditionally, the aroma of coffee is similar, so it is difficult to present the difference. However, in the present invention, there is a feature that a person can present a scent at that timing by guiding the face closer to the image of the product, and a high scent presentation accuracy by using the scent discharge device. It is also suitable for applications that express subtle fragrance differences. In addition, fragrance presentation is easier if the fragrance is clearly different, and the above configuration can be simplified.

As described above, when a passerby is away, it is possible to present an easy-to-accept video and fragrance information, and to present individual or characteristic information as it approaches. Both personal preference and publicity can be achieved.

The configuration of FIG. 11 can also be used as a healing space providing device (spot). Standing in front of the device presents a chemical containing gas. As chemical substances to be mixed in the gas, for example, cypress, lemon, and herbal scents are effective in preventing colds. Eucalyptus and peppermint are effective for hay fever. Since sodium hypochlorite has a bactericidal action, it can be used to prevent infection by dissolving and spraying in water. For example, a refreshing feeling can be obtained by displaying a video of a waterfall and releasing a mist containing these chemicals from the screen. In addition, when high-concentration oxygen is released, fatigue recovery can be achieved.
