Description

  The present invention relates to a conversation assistance device, a conversation assistance system, a conversation assistance method, an information transmission device, an information transmission system, an information transmission method, a control device, a control system, and a control method. It is suitable for application.

  In the current information-oriented society, the infrastructure for information transmission by communication and information retention by storage has been rapidly established. The most sought-after technology based on this foundation is thought to be in two ways: what kind of effective information is captured and how that information is communicated to people. .

The importance of sensors as a means for capturing information is increasing year by year. Many sensors have been developed so far (Non-Patent Documents 1 and 2). These are broadly divided into three types, physical sensors, chemical sensors, and biological sensors, depending on the measurement principle. Among them, a wide variety of sensors are known, such as an optical sensor and a temperature sensor as examples of physical sensors, an ion sensor and a gas sensor as examples of chemical sensors, and a glucose sensor and an immune sensor as examples of biological sensors. .

Among them, functional magnetic resonance imaging (fMRI), magnetoencephalograph (MEG), and the like are known as sensors that can non-invasively measure higher-order functions of humans that are thought to be derived from the brain, such as emotions. Therefore, it is an important measuring device in research fields such as psychology (Non-patent Document 3).

Recently, an optical topography device has been used as a noninvasive and portable brain measurement device (Non-patent Document 4). This optical topography device is large enough to be fixed to a part of the head, and the subject can freely take action. Yes.

  While the above sensor directly measures the function of the brain, it is also considered to measure physiological responses that appear as a result of emotions that have occurred in the brain. Actually, immunoglobulins in saliva, cortisol in blood, and the like are measured with a chemical sensor as an index for measuring the influence of stress (Non-patent Document 3).

Further, in a speech recognition method for recognizing a user's uttered sound, it is known that a speech signal received from a microphone is corrected using a bio signal to compensate for a change in the user's speech due to a change in emotional state. (Patent Document 1). There is also known a speech synthesizer that obtains a user's biological information using a biological information detection device such as an electroencephalogram, body temperature, pulse, sweating, and respiratory rate, and generates synthesized speech according to the acquired biological information. (Patent Document 2). Furthermore, a technique for knowing the emotional state of the user from the pulse rate is known (Patent Document 3).

There is a study that the resting effect is large when the fluctuation of the rhythm is about the reciprocal of the frequency of the rhythm (Non-Patent Document 5).

Moreover, it is known about the electric power generation by the pressure added at the time of a walk (nonpatent literature 7, 8). In addition, a generator that utilizes the temperature difference between the body temperature and the outside air temperature is known (Non-Patent Document 9).

In addition, a method for collecting a small amount of blood by a lab-on-chip using microfluidic technology is known (Non-Patent Document 10).
Akihiro Horiike et al .: “Creation of Healthcare Chip Aiming for Separation and Analysis of Trace Whole Blood”, Medical Electronics and Biotechnology, Vol. 39, Special Issue 2, (2001) It is known that molecular recognition is possible by swelling / shrinkage transition (released by swelling and bonded by shrinkage) (Non-patent Document 11).

  By the way, in the conversation, in addition to the information transmitted through the language, it is considered that the actual information transmission is realized by simultaneously transmitting changes in the atmosphere and gestures due to changes in emotions and the like. For this reason, the purpose of the conversation breaks down because emotions that the speaker is not aware of have been transmitted to the other party, such as the fact that the complaint that you are thinking calmly is actually sent to the other party Will happen. It is important to prevent such communication failures.

  However, until now, no specific proposal has been made for using sensors for the purpose of facilitating human communication. In addition, the sensor used for this purpose needs to be able to sense the emotion of the speaker, but the fMRI and MEG mentioned above as sensors capable of sensing the emotion both require huge devices. Therefore, it lacks the portability required to always use it in conversation situations. In addition, it is considered difficult to continue measurement over time with chemical sensors that measure physiological responses that appear as a result of emotions that occur in the brain. Furthermore, although the optical topography device is non-invasive and portable, there is a problem that the mounting site is limited to the head.

  Furthermore, changes in eye movements and gestures can also be considered as manifestations of emotions. These can be captured using an image sensor using a CCD or the like. However, with this method, it is necessary to capture a change in movement from a slightly distant position, and portability cannot be secured as it is.

Therefore, the problem to be solved by the present invention is to provide a conversation assistance device, a conversation assistance system, and a conversation assistance method that enable a user to smoothly perform a conversation with another person and that are excellent in portability. is there.
Another problem to be solved by the present invention is that an information transmission device, an information transmission system, and an information transmission device that can smoothly communicate with various living organisms including animals such as humans, dogs, and cats and that are excellent in portability. It is to provide an information transmission method.
Another problem to be solved by the present invention is to provide a control device, a control system, and a control method that can control various organisms including animals such as humans, dogs, and cats.

In order to solve the above problems, the first invention of the present invention is:
One or more sensors for detecting the biological information of the user;
Information processing means for performing predetermined information processing based on biological information detected by the sensor;
It is a conversation assistance device characterized by having an output means for outputting a result of information processing.

The second invention of this invention is:
One or more sensors for detecting the biological information of the user;
Information processing means for performing predetermined information processing based on biological information detected by the sensor;
It is a conversation assistance system characterized by having an output means for outputting a result of information processing.

The third invention of the present invention is:
Detecting the user's biometric information with one or more sensors;
Performing predetermined information processing based on biological information detected by the sensor;
And a step of outputting a result of information processing.

  In the first to third inventions, typically, the user is assisted in controlling his / her state based on the output of the output means. The biometric information is biometric information important for the user to smoothly communicate with others, and is typically emotion information. Here, emotion refers to the entire emotional process when the work of the spirit is divided into knowledge, emotion, and will, and includes emotions, moods, and emotions. Here, stress is also included. Emotion changes with, for example, various external stimuli (for example, audio-visual stimuli). At that time, changes in secretions due to the endocrine and exocrine systems are accompanied. Is possible. The sensor for detecting the biological information of the user is preferably one or a plurality of sensors that can be carried by the user continuously and can be continuously measured in order to constantly measure the user's emotions over time. (One sensor or sensor group). Preferably, the user can carry the entire conversation assistance device. In one typical example, a sensor that measures secretions (for example, sweat) from a user's skin surface is used as one of the sensors. As a sensor for measuring the secretion, a surface-plasmon resonance (SPR) chemical sensor is preferably used. As one of the sensors, a sensor that measures blood flow in the user's brain may be used. The sensor for measuring the blood flow is preferably a non-invasive optical topography type sensor. The output means is preferably one or more effectors (a single effector or a group of effectors) that do not interfere with the intended conversation when the measured emotion is conveyed to the user. As one of the effectors, a device that transmits the emotion measured by the above sensor to the user by text information or vibration information can be used. You may use the effector or effector group which assists control of the emotion measured by the sensor. One such effector is a device that gives a rhythmic stimulus to the surface of the user's skin to calm the arousal state, or to reproduce the feeling of holding hands to give a sense of security. A moderately sized device using a soft material can be used.

  A number of conditions are necessary to facilitate the conversation. Examples include an environment suitable for the content being spoken, perfect physical condition, appropriate clothing, composition of the story, easy-to-listen utterance, gestures that express stability, and a sincere atmosphere. Some elements, such as the environment and physical condition, can be changed by the speaker's intention, while others are relatively easy to change depending on the speaker's intention, such as composition and utterance. Above all, it can be said that gestures, atmosphere, vocalization, etc. can be changed to good condition by controlling emotions well. Thus, in this conversation assisting device, for example, the emotion of the speaker is measured, and the emotion is conveyed to the speaker to make it appear, whereby the speaker controls his / her emotion and smoothes the conversation. Such a conversation assistance device includes, for example, one or a plurality of sensors that measure biological information of a user (speaker) and an information processing unit that performs predetermined information processing based on the biological information measured by the sensors. And one or a plurality of effectors for outputting the result of this information processing and transmitting the emotional state to the user.

  Here, as a sensor, a method of measuring the state of the brain that is thought to govern emotions and a sensor that captures physiological and physical changes in the results of emotions are considered. Examples of the former include fMRI, MEG, and optical topography. Further, as the latter, an image sensor, a chemical sensor that captures changes in secretions, a blood flow sensor other than the brain, a pulse sensor, and the like can be considered. Considering that it is necessary to constantly monitor the change over time of “conversation”, it is preferable to use a group of sensors that are portable and capable of continuous measurement (for example, optical topography sensors, secretions on the skin surface). Use chemical sensors to capture, or a combination of them. It is assumed that the optical topography type sensor is incorporated in a thing that naturally touches the head such as a hat. It is assumed that the secretory sensor is incorporated in a wristwatch, a ring, or an effector held by a hand. With this device, changes in the user's emotion over time can be captured naturally and accurately without any stress being measured.

  The effector using the emotion information described above needs to take into consideration the purpose of smoothly promoting conversation with others. That is, for example, in voice information transmission, not only is conversation hampered, but there is also a risk that emotions that the user does not want to convey are eventually transmitted to the conversation partner. Therefore, for example, when an emotion that is likely to be a problem in smoothly proceeding with a conversation such as anger is measured, it is transmitted to the user by a technique that is not visible from the outside, such as vibration or pressure. Also, it is possible to transmit text information only when more detailed emotion information is required. However, it is necessary to prevent the character information from being transmitted to the other party. For example, it is conceivable to use a wristwatch type display. These make it possible to reveal and know one's own emotions and to easily suppress the emotions.

  Here, an effector for assisting emotion control is also considered. The states to be controlled here are excited states such as anger and anxiety. To calm the excitement, an effector that vibrates the hand with a certain rhythm is used. In particular, there is a study that the resting effect is large when the fluctuation of the rhythm is about the reciprocal of the frequency of the rhythm (Non-Patent Document 5). In addition, in order to eliminate anxiety, an effector having an appropriate size and softness that reproduces the state of holding hands is used. This is also expected to have an effect of giving a sense of reality to intangible information such as emotion by sharing it with the sensor and effector for emotion information described above.

  For the measurement of emotion, preferably, the change in emotion is measured by measuring the change in the property of this detection unit when an object such as a secretion secreted from a living body is coupled to the detection unit along with the change in emotion It is also possible to use a sensor that detects a plurality of pieces of information including information on the presence / absence or distribution of an object using the spatial structure of the detection unit. The spatial structure of the detector is typically the geometric structure of the detector. This geometric structure includes, for example, the arrangement and shape of binding sites, and their statistical distribution (for example, when the binding sites are arranged in a regular grid pattern with a certain shape, the displacement and shape from the grid points) Distribution). Examples of the coupling force involved in the coupling between the object and the detection unit include van der Waals force, electrostatic attraction (Coulomb force), hydrogen bonding, and the like. concern. Typically, the detection unit has a plurality of binding sites, and a plurality of objects are selectively bound to these binding sites. These binding sites are appropriately arranged according to the object, but the arrangement may be periodic or aperiodic, and a periodic part and an aperiodic part may be mixed. . Or you may make it give the information of presence distribution of a binding site, without designating sequence information. These binding sites are typically arranged according to the size of multiple objects, and the abundance time of these objects is created by creating steric hindrance using the difference in size of these objects. Change is detected. When the difference in size of these objects is small and it is difficult to detect temporal changes in the amount of the object existing only by the arrangement of the binding sites, for example, a step is provided on the detection surface of the detection unit. You may make it detect the temporal change of the abundance of a target object by producing a three-dimensional obstacle using a level | step difference. Alternatively, it is also possible to create steric hindrance by creating one type of binding site on the metal fine particles. Information extraction is generally performed by measuring changes in the physical properties or structure of the detection part due to the binding of the object to the detection part. Here, as a physical property, the dielectric constant and weight of a detection part are used suitably from a viewpoint which can perform a measurement easily. In addition, the structure is a conformation of a molecule such as a protein, and steric hindrance or the like occurs due to this conformational change.

  An appropriate binding site is used depending on the object. For example, when the object is an immunoglobulin, an antigen can be used as the binding site. That is, the object and the binding site have a relationship of a combination of the antibody and the corresponding antigen, and the fact that the antigen and the antibody are bound by the antigen-antibody reaction is utilized. When the object is a protein, metal fine particles to which an appropriate linker is bound can also be used as the binding site. In addition, even when the object is a general molecule, a polymer that can be specifically bound can be produced by using a molecular imprinting method and used as a binding site (Non-patent Document 11).

  The change in the dielectric constant of the detection unit due to the combination of the objects can be easily performed using the principle of surface plasmon resonance (SPR). This sensor using surface plasmon resonance (SPR sensor) is a sensor capable of sensitively measuring such changes in the system. An example of this SPR sensor has a structure composed of three layers of a binding site, a substrate, and a prism, and measures the binding of an object by a change in the total reflection critical angle of incident light due to the binding of the object. In this case, the change in dielectric constant due to the coupling of the objects contributes to the change in the total reflection critical angle. More details are as follows. That is, incident light is totally reflected at a certain critical angle at the interface between the prism portion having a high refractive index and the substrate portion having a low refractive index. At that time, evanescent light corresponding to the critical angle of total reflection appears at the interface, and surface plasmon resonance occurs when it is appropriately coupled with surface plasmons, which are dense waves of conduction electrons of the substrate. When an object binds to the binding site, the surface plasmon changes with a change in the effective refractive index in the range where the evanescent light reaches, and the critical angle causing surface plasmon resonance changes. This makes it possible to detect a change in the dielectric constant of the system due to the object being coupled to the detection unit.

  Further, the change in the weight of the detection unit due to the combination of the objects can be easily performed using an oscillation circuit and a frequency measurement device. More specifically, it is possible to use an oscillation type sensor that measures a change in the weight of the detection unit when an object is coupled to the detection unit by a change in the frequency when a constant vibration is continuously applied to the substrate. This is an effective technique when the change in the dielectric constant of the system before and after the coupling is not so large.

  Emotions can be measured using mental sweating from palms and soles. Mental sweating occurs from the eccrine and apocrine glands on the palms and soles. Among the eccrine glands present in the whole body skin, it is known that most of the eccrine glands responsible for mental sweating according to emotional changes are present on the palms and soles of the feet (Non-patent Document 6). . Fig. 1 shows the structures of the eccrine and apocrine glands (Fig. 2-1 on page 41 of Non-Patent Document 6). Sweat components include ions, organic compounds, and proteins. Among these ions, sodium (30-120 mM / l), chlorine (10-100 mM / l), potassium (5-35 mM / l), calcium (0.5-10 mM / l), bicarbonate (0-> In addition to 30 mM / l), there are trace amounts of magnesium, manganese, zinc, copper, lead, silver, gold, cadmium, cobalt, and the like. Organic compounds include ammonia (2-8 mM / l), urea (12-27 mM / l), lactic acid (8-40 mM / l), etc., as well as trace amounts of glucose and pyruvic acid. Proteins include trace amounts of albumin, α globulin, γ globulin, glycoprotein, peptide proteolytic enzyme (kallikrein) and the like. The above data are perspiration components from the eccrine gland (Chapter 3, Non-Patent Document 6, p. 64-86). The sweating component from the apocrine gland has many protein components and also contains a fluorescent substance and a pigment component. Changes in the sweat component distribution can be captured by using an ion sensor, an immune sensor, or the like.

  As an example of the above emotional measurement method using mental sweating, consider using mental sweating from the sole of the foot. In order to convey the measured emotion to the user, it is necessary to use a method that does not disturb the conversation and is not noticed by the conversation partner. For that purpose, it is considered that simple attention is transmitted by a vibration device, and when it is necessary to give a specific instruction or the like, it is transmitted by character information. However, since a device that conveys character information cannot be read when worn on a shoe, it is necessary to communicate with another device such as a wristwatch-type device. In order to perform continuous measurement, it is necessary to perform continuous communication, and its power becomes a problem. If it is only necessary to make a measurement only when displaying the result, it is possible to supply power to the sensor through near-field communication using electromagnetic induction or the like. It is desirable to use it. In this case, for example, an electric generator can be embedded in the shoe, and electric power can be generated by pressure during walking (Non-Patent Documents 7 and 8). Moreover, the generator which utilized the temperature difference of body temperature and external temperature can also be utilized (nonpatent literature 9).

Emotion can also be measured by measuring blood substances using a painless needle and a lab-on-chip. It is known that changes in the endocrine system and immune system due to matters related to emotions such as stress appear more directly in blood than saliva and urine (Non-patent Document 3).
As an endocrine system index, many things such as adrenocorticotropic hormone (ACTH), cortisol, catecholamine are known, compared to saliva having one kind of cortisol. As the immune index, only one type of secretory immunoglobulin A is known in saliva and interleukin 6 is known in urine, whereas in blood, white blood cell count, lymphocyte count, natural killer activity, immunoglobulin Many things are known. In particular, in blood, it is possible to measure temporal changes in the distribution of objects from the vicinity of the nervous system to the terminal, such as the flow from ACTH to cortisol and the flow from white blood cells to lymphocytes and immunoglobulins. Become.

  The problem is that the burden on the user is too great with normal blood collection. In this regard, the pain can be greatly reduced by eliminating pain during blood collection using a painless needle and measuring with a small amount of blood collected using a lab-on-chip using microfluidic technology (Non-Patent Document). 10). This makes it possible to always measure blood rich in substances serving as an index for measuring emotions without imposing a great load on the user. For example, the sensor system can be used by being embedded in a wristwatch. By doing so, a vibration device and a display device for transmitting the measured emotion to the user can also be integrated.

  Emotions can also be measured by capturing facial expressions and eye movements of the user. That is, as an index for measuring emotion, it is often performed to capture facial expressions and eye movements. In particular, eye movements and blinks are actively studied as an important index and the relationship with emotions (Non-Patent Document 4). In the measurement of eye movements and blinks, there are roughly divided optical methods and electrical methods. As an optical method, there are an eye camera and an optoelectronic method using infrared rays in eye movement, and there is photographing with a small camera in blinking. An electrical method is an electrooculogram (EOG) method. The EOG method has an advantage that it is possible to measure eye movements and blinks even when the eyes are closed.

  As described above, when emotion is measured by capturing facial expressions and eye movements of a user, it is desirable to embed a sensor in glasses as a sensing method that is portable and does not place a burden on the user. For example, by embedding a camera in a frame portion close to a lens of eyeglasses, it is possible to measure blinks and capture facial expressions. In addition, the eye movement can be captured by embedding the eye camera in the frame above the lens of the spectacles. In addition, by attaching an electrode to a place where it touches the temple of the frame, it is possible to capture eye movements and blinks by the EOG method. As means for transmitting the emotion measured in this way to the user, alerting by vibration and transmission by character information are suitable. Therefore, the device for applying vibration is embedded in the frame of the glasses. Moreover, the display which conveys character information is projected on the inner surface of the lens of the spectacles using a transmission type. In addition, it is also possible to convey emotion information without being known to the conversation partner by voice transmission using bone conduction.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, a wristwatch type conversation assisting apparatus according to a first embodiment of the present invention will be described. FIG. 2 shows this wristwatch type conversation assisting device.
As shown in FIG. 2, the wristwatch type conversation assisting device has a main body 11 and a band 12 connected to the main body 11. The main body 11 includes a clock 13 that displays time and a status display unit 14. The clock 13 and the status display unit 14 are composed of a liquid crystal display, for example. Although not shown, the main body 11 includes an information processing unit and a vibration device including a single chip microcomputer. A sweat sensor 15, a pulse sensor 16, and a blood flow sensor 17 are attached to the inner surface of the band 12. The measurement results obtained by the sweat sensor 15, the pulse sensor 16, and the blood flow sensor 17 are sent as electrical signals to an information processing unit in the main body 11 via a wiring (not shown) embedded in the band 12, and are transmitted in a predetermined manner. After the information processing is performed, the result is displayed on the status display unit 14 with characters or the like. In FIG. 2, one perspiration sensor 15, one pulse sensor 16, and one blood flow sensor 17 are shown. However, the number and arrangement of these perspiration sensor 15, pulse sensor 16, and blood flow sensor 17 are the same. It is not limited and can be selected as needed.

  3A and 3B show a state in which the user wears the wristwatch type conversation assistance device on the wrist, FIG. 3A is a plan view, and FIG. 3B is a cross-sectional view. As shown in FIGS. 3A and 3B, when the user wears this wristwatch-type conversation assistance device on the wrist, the sweat sensor 15, the pulse sensor 16 and the blood flow sensor 17 attached to the inner surface of the band 12 are provided. It is in contact with or close to the surface of the wrist on the side of the palm, and these sweat sensor 15, pulse sensor 16 and blood flow sensor 17 measure sweat, pulse and blood flow, respectively, thereby measuring emotional changes.

For example, when the user is angry as a result of measurement by the sweat sensor 15, the pulse sensor 16, and the blood flow sensor 17, for example, “angry” is displayed. In addition to this, a message for calling attention is displayed on the status display unit 14 according to the status of the user. For example, when the user is angry, a message “Cold conversation” is displayed (see FIG. 3A). Depending on the measurement results of the perspiration sensor 15, the pulse sensor 16, and the blood flow sensor 17, instead of the display on the state display unit 14 or together with the display on the state display unit 14, vibration is generated by the vibration device. It is also possible to convey the state to the user by transmitting to the user's wrist. In this case, the user can obtain information such as feeling angry by sensing this vibration.

It can be measured constantly. Then, when there is an undesired change in emotion during conversation, the manner and content of conversation are corrected according to the content displayed on the display unit 14 of the wristwatch type conversation assistance device and the vibration transmitted to the wrist by the vibration device. Can do. For this reason, a conversation with another person can be performed smoothly. Further, this wristwatch type conversation assisting device can be configured to be small and light, and is excellent in portability.

Next explained is the fifth embodiment of the invention.
In the fifth embodiment, a sensor that is effective when applied to emotion measurement in a conversation assisting device or the like will be described.
When the distribution of a plurality of substances (objects) existing in the system to be measured changes with the state of the system, a sensor that measures the distribution of the plurality of substances and the change over time is important. Here, in the system in which two kinds of substances exist, in addition to information on the distribution of the substances, a sensor structure is provided that can measure information that the abundance ratio changes with time.

  As the simplest example, consider the case of measuring two types of objects a and b having shapes as shown in FIG. Assume that the sizes of these objects a and b are d (a) and d (b), respectively, and they are almost equal to each other. On the other hand, the sizes in the direction orthogonal to d (a) and d (b) have the ratio shown in FIG. 14 and are quite different from each other.

As shown in FIG. 15, in this sensor, two types of binding sites A and B that can selectively bind each of the objects a and b to one main surface (surface) of the substrate 61 are appropriate. Alternating positions. Here, these binding sites A and B are periodically arranged so as to form a face-centered plane lattice when attention is paid to each. Further, the distance between the closest binding sites A and the distance between the closest binding sites B are determined so that the objects a are three-dimensional at all the binding sites A when each of the objects a and b is independently bonded. It is selected so that it can be simultaneously bonded without being obstructed, and the object b can be simultaneously bonded to all the binding sites B without being sterically hindered. Specifically, for example, the distance between the nearest binding sites A and the distance between the nearest binding sites B are selected to be slightly larger than d (a) and d (b).
An appropriate combination of the objects a and b and the binding sites A and B is selected according to the objects a and b. Specifically, for example, when the objects a and b are immunoglobulins, use a combination of an antigen and an antibody that specifically binds by an antigen-antibody reaction or a metal fine particle to which an appropriate linker is bound. Can do.

Next, a method for using the sensor configured as described above will be described.
First, a sensor is installed in a system (for example, liquid phase or gas phase) where the objects a and b exist.
Consider a case where the existence ratio of the object a is high at this setting and the existence ratio of the object b is increased later. In this case, first, as shown in FIG. 16, a large number of objects a are bonded to the binding site A of the substrate 61, and then the object b is also bonded to the binding site B without any steric hindrance.

  On the other hand, considering the situation opposite to the above in which the presence ratio of the target object b is high first and the presence ratio of the target object a later increases, as shown in FIG. Due to the steric hindrance due to the binding, a situation occurs in which the increased object a hardly binds to the binding site A. Therefore, by measuring this difference, the temporal change in the state of the system, more specifically, whether the existence ratio of the object a is high at the beginning and the existence ratio of the object b is increased at the beginning, It can be specified whether the existence ratio of the object b is high and the existence ratio of the object a is increased later.

In order to actually measure the difference between the two states, for example, an SPR sensor is used when the dielectric constants of the objects a and b are different from each other, and a crystal oscillation type sensor is used when the weights of the objects a and b are different from each other. Measurement may be performed using.
FIG. 18 shows an example in which measurement is performed using an SPR sensor. This SPR sensor is configured by bringing a prism into contact with the other main surface (back surface) of the substrate 61, and allows the monochromatic light such as laser light to enter the prism from the outside. As shown in the left diagram of FIG. 18, when the objects a and b are also coupled, the SPR is obtained when incident light is incident on the other main surface of the substrate 61 at an incident angle θ ₁ equal to the critical angle. Get up. On the other hand, when only the object b is coupled as shown in the right diagram of FIG. 18, when the incident light is incident on the other main surface of the substrate 61 at an incident angle θ ₂ equal to the critical angle. SPR occurs. At this time, since θ ₁ ≠ θ ₂ (θ ₁ > θ _{2 in} this example), by measuring this difference, the state in which the objects a and b are also coupled to one main surface of the substrate 61; A state in which only the object b is combined can be easily identified.

  As described above, according to the fifth embodiment, the binding sites A and B that selectively bind to the objects a and b to be measured are appropriately formed on one main surface of the substrate 61 that is the detection unit. By observing the state of the binding of the objects a and b to these binding sites A and B by arranging them at appropriate positions, the presence / absence of these objects a and b can be detected with a single sensor. In addition to information on non-existence or distribution, information on temporal changes in the existence ratios of these objects a and b can also be extracted. That is, by controlling the geometric structure of the detection surface of the substrate 61, geometric information processing can be performed on the objects a and b inside the sensor, and a large amount of information is processed into a necessary shape and taken out to the outside. be able to.

Next, a sixth embodiment of the present invention will be described.
In the sixth embodiment, as in the fifth embodiment, a sensor that is effective when applied to emotion measurement in a conversation assistance device or the like will be described. This sensor is suitable when the shapes and sizes of the objects a and b to be measured are not so different from each other.
In the sixth embodiment, a case is considered in which two types of objects c and d having shapes as shown in FIG. 19 are measured. Assume that the sizes of these objects c and d are d (c) and d (d), respectively, and they are almost equal to each other. In this case, the sizes in the direction orthogonal to d (c) and d (d) are substantially equal to each other.

  As shown in FIG. 20, in this sensor, two types of binding sites C and D to which each of the objects c and d can selectively bind to one main surface of the substrate 61 are alternately arranged at appropriate positions. The arrangement is the same as in the fifth embodiment. In this case, a concave portion 62 having a rectangular cross section is provided by fine processing in a portion corresponding to the binding site C on one main surface of the substrate 61. Unlike the fifth embodiment, the coupling site C is provided on the bottom surface of the recess 62 and the coupling site D is provided on the upper portion of the step formed by the recess 62.

Next, a method for using the sensor configured as described above will be described.
First, a sensor is installed in a system where the objects c and d exist.
With this setting, consider the case where the existence ratio of the object c is high first and the existence ratio of the object d is increased later. In this case, first, as shown in FIG. 20, a large number of objects c are bonded to the binding site C of the substrate 61, and then the object d is also bonded to the binding site D without any steric hindrance.

On the other hand, considering the situation opposite to the above in which the existence ratio of the object d is high at first and the existence ratio of the object c is increased later, as shown in FIG. Due to the steric hindrance due to the binding, a situation occurs in which the object c increased after that hardly binds to the binding site C. Therefore, by measuring this difference, the temporal change in the state of the system, more specifically, whether the existence ratio of the object c is high at the beginning and the existence ratio of the object d is increased later, It can be specified whether the existence ratio of the object d is high and the existence ratio of the object c is increased later.
Since the other than the above is the same as that of the fifth embodiment, the description is omitted.

FIG. 22 shows specific examples of the objects c and d and the binding sites C and D. In this example, the objects c and d are x: serum albumin and y: streptavidin, and the binding sites C and D are X: HS-Cys and Y: disulfide biotin analog (disulfide), respectively. -biotin analogue), each having a size as shown in FIG. The substrate 61 is a gold substrate, and X and Y are bonded to the gold substrate using thiol or the like. Furthermore, as shown in FIG. 23, in this case, the distance between the nearest binding sites A and the distance between the nearest binding sites B are about 10 nm. FIG. 24 is a diagram corresponding to FIG. 20, where x is combined with X and y is combined with Y.
According to the sixth embodiment, even when the shapes and sizes of the objects c and d to be measured are substantially equal, the same advantages as those of the fifth embodiment can be obtained.
