  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating an outline of a biological measurement system according to a first embodiment of the present invention. Taking the theater 400 as an example, a spectator seat is provided for the stage, and a plurality of spectators who are subjects are seated. From the subject, position information corresponding to each is obtained.

As biological information, in addition to brain function information obtained from a biological optical measurement device, brain function measurement information such as electroencephalograph and brain magnetic field measurement, electrocardiogram measurement, ultrasonic heart and vascular pulsation measurement, ultrasonic Doppler blood Flow measurement, peripheral pulse wave measurement by light, cardiac function measurement information such as venous return measurement by light, vibration measurement by acceleration sensor, voice measurement by microphone, exercise information by touch sensor, temperature sensor, mouse, keyboard, camera, etc. Muscle information and the like can be used.

  In the centralized control device 200, the biological information of each subject and the position information of each subject are merged, analyzed, and the measurement result is displayed.

  FIG. 2 shows a schematic configuration of the living body measurement system according to the first embodiment of the present invention. Each subject's measurement terminal 100 is connected to the LAN 500 and is connected to the centralized control device 200 via the LAN. Each subject's position measuring means is also connected to the LAN 500. The biological information of each subject and the position information of each subject are collected in the centralized control device 200 and analyzed and displayed. In FIG. 2, the measurement terminal 100 and the centralized control device 200 are connected by a wired cable, but may be wirelessly transmitted using a wireless communication device.

  This living body measurement system enables real-time measurement of up to 40 people at the same time, for example.

FIG. 3 shows an example of the biological light measurement device included in the measurement terminal. The living body light measurement device detects light that is incident on light and that is scattered and absorbed in the living body and propagates. Light irradiated from one or more light sources 31 included in the apparatus main body is incident on the subject 300 through the waveguide 33. The light enters the subject 300 from the irradiation point 39, passes through and propagates through the subject 300, and then passes through the waveguide 33 from the detection point 40 at a position distant from the irradiation point 39. It is detected by the photodetector 34. Here, the light source 31 may be a semiconductor laser (LD), a light emitting diode (LED), or the like, and the photodetector may be a photodiode (PD), a photomultiplier tube (PMT), or the like. The waveguide 33 may be an optical fiber or the like.
The light source 31 is driven by a light source driving unit 32 controlled by the control unit 37. The gain of one or more photodetectors 34 is controlled by the control unit 37. The control unit 37 receives an input such as a driving condition from the input / output unit 38.
The electrical signal photoelectrically converted by the photodetector 34 is amplified by the amplifier 35, converted from analog to digital by the analog-digital converter 36, sent to the control unit 37, and output from the input / output unit 38.

  The measurement terminal 100 may be provided with another biological measurement device such as an electroencephalograph integrally with the biological light measurement device, or may be provided separately from the biological light measurement device.

  FIG. 4 is a block diagram illustrating a schematic configuration of the centralized control device 200. The centralized control device 200 has an input unit 41 for inputting biological information measured by each measurement terminal 100, a storage unit 42 for storing measurement data input from each measurement terminal, and processing the measurement data to calculate necessary information. The analysis unit 43 includes a display data creation unit 44 that creates data suitable for display based on the analyzed information, and a display unit 45 that displays measurement results. Position information from the subject position measuring means is also input from the input unit 41. Further, an input means 46 such as a keyboard and a mouse for inputting necessary commands is provided.

In the analysis part 43, the evaluation value (index) which shows an activity condition is calculated based on the biometric information obtained from each test subject. The analysis unit 43 is provided with an activation degree calculation unit 49, which calculates the activation degree of a specific part of the brain based on the cerebral blood flow data of the specific part of the brain of each subject.
When the brain is activated, the amount of blood flowing increases, but the light used for measurement is absorbed by the blood with respect to the increase in blood volume, so that the intensity of light detected by the photodetector decreases. The cerebral blood flow data of the subjects A to D shown in FIG. 5 is obtained from the measurement data of the photodetector. FIG. 5 is a schematic diagram showing the magnitude of cerebral blood flow on the vertical axis with respect to time on the horizontal axis. Even for the same stimulus, the response of each subject varies, and the temporal change in cerebral blood flow data varies depending on the subject.
The activation degree of the brain can be obtained by time-integrating the cerebral blood flow data of FIG. 5, and it can be evaluated that the greater the integration value, the higher the activation degree of the brain.

  The present invention measures cerebral blood flow data of each part of the brain using at least a living body light measurement device. In addition, other biological information may be measured by an electroencephalograph or a cardiac function measuring means.

A person changes the activity of a specific part of the brain, the relationship of the active part, and the like according to emotions and moods.
For example, frontal lobe blood flow in 46 areas of the brain is associated with short-term memory and mood. In addition, the frontal lobe blood flow in 10 areas of the brain is related to suppression and concentration, and these functions affect the motor cortex and ultimately the behavior. Heart rate, LF / HF, and the like reflect the functions of sympathetic nerves and parasympathetic nerves belonging to the autonomic nervous system, and are related to the state of excitement and rest. Furthermore, the occipital brain wave of P300-like reaction obtained from an electroencephalograph is associated with visual attention and the like. Broadly speaking, the rear part of the brain has many functions to process information inputted from the sensory organs, and the front part of the brain has many functions to judge and execute an action to be output.

  As mentioned above, because many parts of the body are active depending on the measurement of cerebral blood flow (blood volume) by light, complex higher-order functions (mood, language function, learning, etc.), which are relatively slow activities, are measured. It is suitable to measure relatively quick visual attention (mainly occipital lobe) in a meter.

  For example, it is possible to extract a scene that is visually attentive while appreciating a video / entertainment, etc., and to measure a viewer's mood with respect to the scene of interest. For example, when the desired response (eg, raising) is not obtained in an arbitrary scene, the information is sent to the five senses information presentation device shown in FIG.・ Give taste information, visual information, and auditory information. In order to realize these, a presentation device suitable for each sense is incorporated in the five-sense information presentation device. Alternatively, each spectator wears a Trans-Cranial Magnetic Stimulation (TMS or Transcranial Magnetic Stimulation Device) device that can give a stimulus to any place in the brain by a magnetic field. The brain is stimulated directly by the analyzed information (five sense information stimulator).

  In FIG. 4, the activation degree of the brain of each subject calculated by the activation degree calculation unit 49 is associated with the position information obtained by the subject position measurement unit 48, and the display data creation unit 44 displays each subject. The data for display is created by associating the analysis result with the position information.

FIG. 6 is a display example of the display unit 45 that displays the calculation results of the activation levels of a plurality of parts of the brain by the biological light measurement device and the biological information obtained from other measurement devices in association with the position information of the subject. It is shown.
In FIG. 6, the upper left (a) shows the frontal lobe blood flow in 46 areas of the brain, the upper right (b) shows the frontal blood flow in 10 areas of the brain, and the lower left (c) shows the heart rate, LF / HF, and the like. The lower right (d) schematically shows the occipital lobe electroencephalogram. As shown in the figure, the larger the value such as the activation degree, the darker the color may be displayed, or the area may be changed or the color may be changed.

  In FIG. 6, four observation results are displayed on one display screen, but one detection result may be displayed on each display screen, and the screen may be switched.

  For lectures in the hall and classrooms, the display unit 45 may be provided at the speakers and teachers. The lecturer and teacher can know the sleep and concentration levels of each audience and students by looking at the screen of the display unit 45 shown in FIG. 6, and can reflect this in the progress of the lecture and class. In theaters and comics, it is possible to know the emotional state of the audience and reflect it in the performance.

In this embodiment, an example of use in a theater or classroom has been described, but the present invention can also be used outdoors. It is possible to display the reactions of the audience such as concerts and speeches at the plaza and playground.
Such information is useful not only for the basic data of feedback to the audience, but also for the performer to change the performance based on the evaluation by feeding back to the performer performing the performance in real time.
The figure shown in FIG. 6 is displayed on the monitor, but lighting is provided around the seats in the hall, and red lighting is used when the signal strength is high, and blue lighting is used when the signal strength is low. From the stage, you can read the state of the venue at a glance.
Such a system can be realized for the first time by associating the biological measurement apparatus with the position information of the person to be measured.

In the above description, a narrow space has been described as an example. However, as position information, not only a position on a plane in a theater or a plaza, but also high-level information can be included as necessary.
By displaying a map of the relationship between altitude information and biological information, the relationship between weather / atmospheric pressure and biological information can be clarified. For example, it is known that immune function and anesthesia are highly related to atmospheric pressure, but the wearable biological measurement system enables the analysis of the relationship with altitude information and atmospheric pressure information. It becomes possible.
In addition, when analyzing the propagation of individual moods, etc., an index such as activation degree is obtained every predetermined time, and the time is advanced and displayed, so that changes with time progress, for example, multiple audiences It is possible to observe the propagation of emotions at a glance. The time origin may be absolute time, may be the timing of an event, or both may be selected.

  FIG. 7 shows an outline of the biological measurement feedback system according to the second embodiment of the present invention.

  In the first embodiment, the biological information of each subject obtained from the measurement terminal 100 and the location information of the subject are analyzed in association with each other, and the result is displayed in association with the location of the subject. In the present embodiment, the analysis result is indexed by the central control device 200 and fed back to the subject 300 by the five sense information presentation device. For example, based on the biological information, feedback to the five sense information presentation or the five sense information stimulation device attached to each seat, or feedback to the wearable device worn by the subject. Specifically, in the diagram showing the configuration of the centralized control device in FIG. 4, a feedback signal creation unit 51 is provided, and the five sense information presentation or five sense information stimulation device 52 is provided according to an index such as the degree of activation obtained by the analysis unit 43. A drive signal to be operated is created, and the five sense information presentation or the five sense information stimulation device 52 is operated by this drive signal.

  As the five sense information presentation or the five sense information stimulating device 52, any device that appeals to the five senses of the subject may be used. For example, a lamp is turned on, an image is displayed, a sound is emitted from a speaker, or vibration is caused by a seat or a wristband. Or just add.

The following example can be considered as the content of feedback.
For example, if a sleeping state is observed by analysis of biological information for a student in a classroom or a spectator listening to a lecture in a hall, a sound that gives vibration, a stimulating odor, or a surprising sound , Give light with a high color temperature, or display a warning image.
In addition, it discriminates the state of concentration (eg, visual attention information of the occipital visual cortex, cognitive attention from the blood flow of the prefrontal cortex), and the five sense presentation device gives the five sense information to concentrate. You can do it.
Also, if you are excited, turn the seat background red, and if you are listening, not concentrating, or sleeping, make the seat background blue.

  For use with multiple cars traveling on the road, it is only necessary to measure the biological information of multiple drivers and use the analysis results to control their own cars or to give danger information to other people's cars . In addition, traffic control can be performed by signals, car navigation, etc., from the distribution of car movement and driver drowsiness.

  The feedback may be made to each subject individual or may be fed back to all persons who are close to the conditions. For example, in the classroom, when the concentration of students on the window side is generally low, feedback may be provided to all the students on the window side.

  By displaying feedback information in the same way on the monitors in front of the performers and teachers on the stage, the performers and teachers on the stage can objectively evaluate their performance and make corrections appropriately according to the situation of the audience and students. Can do.

  The transmission of information is expected to vary from region to region or from country to country. Also, the response to a single event is expected to vary from region to region or country.

  In this embodiment, the measurement terminal 100 is connected to the Internet, and the biological information of each subject 300 is collected via the Internet, and is analyzed and displayed.

  FIG. 9 shows a schematic configuration of the living body measurement system according to the third embodiment. The measurement terminal 100 of each subject 300 is connected to the Internet network 600 via a personal computer or the like, and the biological information of each subject is collected in the central control device 200 via the Internet network 600. In this embodiment, the position information may be sent together with the biological information by providing a GPS device in the measurement terminal, for example. Alternatively, the location information may be obtained from the location of the router by network access, or the non-measurement person may designate the location information from the map information from the network. Also in the present embodiment, the measurement terminal may further include an electroencephalograph, an electroencephalograph, a cardiac function measurement unit, or a muscle motion detection unit.

  The subject may determine a representative subject for each region or each country, or obtain an average of a plurality of subjects in the region or country, and calculate the average value for the living body in that region or that country. It may be information.

  In FIG. 10, the example of a display of the measurement result of Example 3 is shown. The upper left figure (a) shows a brain wave alpha wave related to sleepiness and relaxation, the upper right figure (b) shows a brain wave related to sleep level, and the lower left figure (c) shows excitement / rest. The figure which shows heart rate, LF / HF, etc. relevant to a degree etc., and the figure (d) of the lower right are the schematic diagrams made into the figure which shows the activity condition of the 2nd language relevant to the activity of a language field. For example, as shown in the figure, each indicator may be displayed in different shades depending on the value, for each region or for each country, or may be displayed with different areas or colors. .

  According to the present embodiment, it is possible to measure the difference in information transmission, the difference in reaction, and the like for each region and country in the country.

Further, by obtaining an index such as the degree of activation every predetermined time and displaying the time as it progresses, it is possible to observe at a glance the change accompanying the progress of time.
For example, it is possible to observe differences in area and culture, viewing, etc., by displaying biometric information on a map around the world, starting from the moment when viewing the distribution information on the Internet or the natural disaster. For example, after a video that is a video distribution site such as YouTube is distributed, the response is likely to vary depending on the position on the earth. These differences in biological reactions can be used for marketing and other purposes.
Also, the sunshine hours for each latitude and season vary greatly. Therefore, the reaction to light varies depending on the people living in the area. Macroscopic analysis of these differences in biological responses that change depending on the local natural conditions is important for academic purposes, but can be used for marketing and other purposes.
It can also be used as a trigger to start communication such as searching for people who have similar reactions to events in the world, or people who show the opposite reactions.
