Description

  The present invention relates to a living body contact data measuring apparatus and a living body contact data measuring system, and more particularly to a living body contact data measuring apparatus, a living body contact data measuring system, and a living body contact for measuring contact data between human bodies or human bodies and animals. The present invention relates to a data measurement method.

  In recent years, as a communication technology, a social networking service using the Internet using a mobile phone or a portable information terminal has been proposed. On the other hand, the importance of direct communication between humans is being recognized again, and the development of measuring devices and systems for this purpose is being promoted.

  For example, an electrical signal transmitted from an electronic device attached to one person by touching hands with each other by a plurality of people equipped with electronic devices with communication functions can be transmitted to the electronic device attached to the other person. There is an information exchange system that receives and exchanges information with each other (see, for example, Patent Document 1).

  In facilities that educate children with brain disorders or hospitals that treat children with brain disorders, place multiple children in the same room and observe the behavior of each person to study educational and therapeutic methods. doing.

  In such studies, each child often performs a single action without cooperation, and the children rarely touch each other directly. However, if each child is instructed to touch each other as a play, the number of times of contact with each other will increase even if they are separated from each other, and the children may change to play together.

  In this way, more efficient teaching and treatment methods can be achieved by accumulating contact data such as the number of times children touch each other and the type of contact (classification of differences in hand-to-hand contact direction and contact position). It is considered possible to study and to find new methods from the accumulated contact data.

[Usage of living body contact data measuring device]
It is a figure which shows typically the use condition of one Example of the living body contact data measuring apparatus by this invention. As shown in FIG. 1, the inter-body contact data measurement device 10 is configured to be worn on the wrist of each measurement subject, for example. When measurement subjects equipped with the inter-biological contact data measurement device 10 make the hands 12 and 14 contact each other, transmission / reception of identification data (ID) registered in advance between the two inter-biological contact data measurement devices 10 is performed. Is done.

  At that time, the identification data transmitted from the electrodes 20A and 20A ′ of one inter-vivo contact data measuring device 10 is transmitted using the hands (human body) 12 and 14 as a transmission path, and the other inter-biological contact data measuring device 10 The signals are received by the electrodes 20B and 20B ′. As described above, the pair of living body contact data measurement devices 10 can transmit and receive the identification data of each measurement subject via the human body. The inter-body contact data measurement device 10 also has a function of returning the received identification data, and transmits the identification data of itself and the identification data of the other party together. Thereby, the living body contact data measurement apparatus 10 recognizes that they have contacted each other by receiving the identification data transmitted by itself.

  As a communication method between living bodies by the living body contact data measuring device 10, for example, a communication method for transmitting radio waves to the human body, a communication method for transmitting a weak current to the human body, or a communication method using an electric field may be used. good. In addition, in the case of a communication system using radio waves or electric fields, transmission loss can be reduced, and contact data of various contact modes such as octopus, piggyback, and arms can be measured. Further, in the present embodiment, a distance measurement method using a characteristic in which a signal propagation distance is different due to a difference in frequency as described later is used. For example, a pair of frequencies is appropriately modulated in a frequency range of 5 MHz to 10 MHz. The distance between the living body contact data measuring devices 10 is obtained.

  In addition, according to the communication method using radio waves, the orthogonal frequency division multiplexing (OFDM) method adopted in mobile phones can be adopted, eliminating the change in frequency characteristics due to each human body. can do. In the orthogonal frequency division multiplexing modulation system, orthogonality is used, and overlapping on the frequency axis is allowed, so that a plurality of carriers are closely arranged without interfering with each other, but in a narrow frequency range. Wideband transmission that efficiently utilizes the network becomes possible. In the present embodiment, any communication method may be used, and may be appropriately selected from each communication method.

Further, in the communication method using the human body as a transmission path, the transmission loss is determined by the impedance of each human body and the distance L between the pair of living body contact data measuring devices 10. Therefore, since the impedance characteristics and the distance L change due to the difference in the contact position between the hand 12 and the hand 14, it is possible to determine the contact mode of the two measurement subjects (which part of the measurement subject is touched). It becomes possible to do.
[Configuration of Biological Contact Data Measuring Device 10]
FIG. 2A is a perspective view of the inter-body contact data measuring device 10 as seen from the front side. FIG. 2B is a perspective view of the inter-body contact data measuring device 10 as seen from the back side. As shown in FIG. 2A and FIG. 2B, the inter-body contact data measurement device 10 is attached to an arbitrary part such as a wrist, an elbow, or an arm of a measurement subject, and is held by the attachment belt 30. It has a measurement unit 40 and a plurality of light emitting members 50 attached to the outer surface of the mounting belt 30.
The attachment belt 30 is provided with Velcro (registered trademark) 32 and 34 on the surface of each end portion so that the attachment / detachment operation can be easily performed. The light emitting member 50 is made of, for example, a light emitting diode, and an arbitrary light emission intensity, lighting pattern, and light emission color are switched according to the signal level strength (voltage value) of the received identification data.

The measurement unit 40 is provided with a pair of electrodes 20 on the lower surface for transmitting and receiving identification data. A touch panel 42 is provided on the upper surface of the measurement unit 40. The touch panel 42 functions as a display device that displays the transmitted and received identification data as symbols and an input device that displays various operation buttons (such as a start button, a stop button, and a mode selection button). Of course, the touch panel 42 may be provided in the measurement unit 40 or a plurality of microswitches may be provided in place of the measurement unit 40.
The plurality of light emitting members 50 are made up of light emitting diodes (LEDs), and when they receive identification data from other measurement subjects, emit light and notify that they are touched. Further, when the contact state continues, each light emitting member 50 gradually changes the light emission color with the lapse of the contact time, so that the surrounding people are in contact with each other to be measured. To inform.

In addition, it sets so that luminescent color may differ with the biological body contact data measuring apparatus 10, for example, a male light-emits green, and a female light-emits red. And if the state which the man and the woman contacted is continued, both living body contact data measurement apparatus 10 will change the luminescent color of the light emission member 50 to yellow which is an intermediate color, and both contact states are continuing. Display. Further, when the light emitting member 50 is caused to emit light, it is possible to appropriately change the light emission intensity and the light emission / extinguishing lighting pattern according to the reception level of the contact data.
[About contact style]
In the contact mode, in order to distinguish the types of contact between measurement subjects, impedance characteristics for each contact pattern are measured and registered in a memory and a database.

  As shown in FIG. 3A, the contact pattern 1 is an impedance Z1 when the hands 12 and 14 of the two measurement subjects shake hands and the distance LA between the pair of living body contact data measuring devices 10 and 10 is present. Are measured and stored in the memory and database of the inter-body contact data measuring device 10 in time series.

  As shown in FIG. 3B, the contact pattern 2 is a case where the fingertips of the two hands 12 and 14 of the measurement subjects are in contact with each other, and a distance LB between the pair of living body contact data measurement devices 10 and 10. The impedance Z2 is measured and stored in the memory and database of the inter-body contact data measuring device 10 in time series.

  As shown in FIG. 3C, the contact pattern 3 is a case where the hand 14 of the other measurement subject contacts the elbow 16 of one measurement subject, and the distance between the pair of inter-body contact data measurement devices 10 and 10. The impedance Z3 at the time of LC (= L1 + L2) is measured, and is stored in the memory and database of the inter-body contact data measuring device 10 in time series.

  As shown in FIG. 3D, the contact pattern 4 is a case where the hand 14 of the other measurement subject contacts the shoulder 18 of one measurement subject, and the distance between the pair of living body contact data measurement devices 10 and 10. The impedance Z4 at the time of LC (= L1 + L2 + L3) is measured, and is stored in the memory and database of the inter-body contact data measuring device 10 in time series.

Thus, by registering the impedance characteristics for each contact pattern in a memory or database in advance, it becomes possible to easily determine the contact pattern of each measurement subject. Note that the types of contact patterns are not limited to the contact patterns 1 to 4 described above, and by registering other contact patterns, the types of contact patterns that can be identified can be increased to 20 to 30 types. Yes, a finer contact pattern can be discriminated. Therefore, the contact pattern can be determined by measuring the reception level (reception strength) of the identification data transmitted from the other party and comparing the reception level (measurement value) with the threshold value for each impedance characteristic.
[About contact patterns of multiple side-handed subjects]
As shown in FIG. 4, for example, three measurement subjects N1 to N3 as measurement targets are equipped with the inter-body contact data measurement device 10 on both wrists. And when each measurement object person N1-N3 plays with the game which connects each hand, identification data is transmitted / received between each living body contact data measuring apparatus 10, when connecting a hand. At that time, the control device of the inter-body contact data measurement device 10 performs the control process described later to acquire the identification data of the person holding the hand and transmits the identification data of the person to the other party.

  Further, the inter-biological contact data measuring devices 10 attached to the wrists of the measurement subjects N1 to N3 have different propagation path distances L depending on what is attached to the right wrist and what is attached to the left wrist. . Therefore, in the present invention, frequency modulation is performed using the fact that the reach distance varies depending on the frequency of the high-frequency signal to be transmitted, so that from one living body contact data measuring device 10 to the other living body contact data measuring device 10. Measure distance. Therefore, by repeating transmission and reception while performing frequency modulation, it is possible to determine whether the identification data is received by the living body contact data measuring device 10 on the left or right wrist.

  For example, when the measurement subjects N1 to N3 join hands in a row, the identification data of neighboring people is transmitted and received between the measurement subjects N1 and N3 via an intermediate measurement subject N2. Identification data is transmitted and received. In addition, in FIG. 4, although each measurement subject N1-N3 has shown as an example the case where a hand mutually contacts a hand, as a contact mode of each person, as above-mentioned, an elbow, Any part of the body such as the shoulders, back, waist, and feet may be touched.

  In addition, by attaching the inter-body contact data measurement device 10 to the neck of the dog D (measurement target), when the measurement subject N3 contacts the head of the dog D, the identification data of the dog D is transmitted and received. Therefore, transmission / reception of identification data is performed between each inter-vivo contact data measurement device 10 of the measurement subjects N1 to N3 holding hands and the inter-body contact data measurement device 10 attached to the dog D.

  By giving rules such as a contact method to each measurement subject N1 to N3, various contact patterns are performed, such as contacting another measurement subject or contacting a dog D while changing the relative position of each person. In addition, it becomes possible to measure contact data according to the movements of the measurement subjects N1 to N3 and the dog D in real time.

In this way, by attaching the inter-body contact data measuring device 10 to each other, it is possible to measure and record contact data such as the number of times of contact with the plurality of measurement subjects N1 to N3 and the dog D and the contact mode. become. In addition, when an animal other than a dog is kept as a pet, for example, by installing the inter-body contact data measurement device 10 on a cat, a hamster, a pony (small horse), etc. Contact data such as the contact mode and the number of contacts can be measured and recorded.
[Mesh network formation]
Next, a case where a plurality of measurement subjects N1 to N5 are in contact with each other while freely moving to form a mesh network will be described.

  As shown in FIG. 5A, when the measurement subjects N1 to N5 are in the same room, they are usually not in contact with each other. In FIGS. 5A to 5E, the measurement subjects N1 to N5 are represented by “◯”, the arms of the measurement subjects N1 to N5 are represented by “−” extending in the radial direction from the outer periphery of “◯”, and The hands of the measurement subjects N1 to N5 are represented by “·”.

  When the measurement subjects N1 to N5 are in a non-contact state, the inter-body contact data measurement device 10 attached to each measurement subject N1 to N5 does not transmit or receive identification data. Here, the observer gives one rule to the measurement subjects N1 to N5. For example, instruct people to join hands with the neighbors to make a group of two people.

  As shown in FIG. 5B, for example, the measurement subjects N1 and N2 hold hands, and the other measurement subjects N4 and N5 hold hands. And measurement object person N3 does not touch a hand with anyone. In this state, the inter-biological contact data measuring devices 10 of the measurement subjects N1 and N2 holding hands transmit and receive the identification data and store the identification data received in time series. Further, the identification data received by each of the inter-biological contact data measuring devices 10 of the different measurement subjects N4 and N5 by transmitting and receiving the identification data is stored in time series. The inter-body contact data measurement device 10 of the measurement subject N3 does not transmit / receive identification data. Since each inter-vivo contact data measurement device 10 has the light emitting member 50, it receives other identification data and emits light from the light emitting member 50 to indicate that it is in contact with surrounding people. Thereby, since each measuring object person N1-N5 can visually recognize the person who connected the hand and the person who is not connected, he can participate in the contact game while enjoying more like a game.

  Here, for example, the observer changes the rule by instructing that a person holding hands follows a person who does not hold hands and catches them.

Then, as shown in FIG. 5C, the measurement subjects N1 to N5 escape from the measurement subject N3, while the other measurement subjects N1, N2, N4, and N5 hold hands, Chasing and catching. The movement of each measurement subject N1 to N5 and the change in the contact state at this time are represented by the light emission intensity, the lighting pattern, the light emission color, and the volume from the speaker of the light emitting member 50 of the inter-body contact data measurement device 10, Each measurement subject N1 to N5 reacts with eyes and ears while moving, and repeats contact and non-contact. Therefore, even a person whose measurement target is weak in hearing or a person with poor vision can participate in the game.
Further, the observer instructs the measurement subjects N1 to N5 so that all of them join hands, and changes the rule. Then, as shown in FIG. 5D, each of the measurement subjects N1 to N5 forms a ring in an attempt to bring the hands that are not in contact with each other. Each inter-vivo contact data measurement device 10 attached to each of the measurement subjects N1 to N5 receives the identification data transmitted by the subject via each measurement subject, so that each of the measurement subjects N1 to N5 forms a ring. And the data is recorded in the memory in time series.

  Further, as shown in FIG. 5E, when 10 measurement subjects N1 to N10 are equipped with the inter-body contact data measurement device 10 and each person is instructed to form a group freely, it is distributed to a plurality of groups. Then, the contact pattern is changed while repeating contact and non-contact with each other.

  The inter-body contact data measurement device 10 attached to each person by making contact and non-contact while a plurality of measurement subjects move in this way forms a mesh network MN. In the mesh network MN, the inter-body contact data measurement device 10 of each measurement subject transmits and receives identification data while switching between the parent node (transmission side) and the child node (reception side).

  Therefore, in the living body contact data measuring method of the present invention, the plurality of living body contact data measuring devices 10 attached to the plurality of measuring subjects N1 to N10 are defined by the contact form of the plurality of measuring subjects N1 to N10. Form any mesh network MN. Therefore, each inter-vivo contact data measurement device 10 attached to a plurality of measurement subjects N1 to N10 functions as a parent node or a child node constituting the mesh network MN according to the contact position, and each node includes a plurality of nodes. As the contact relationship between the measurement objects changes depending on the positions of the measurement subjects N1 to N10, the parent node or the child node is switched as the contact relationship between the measurement objects changes. Memorize.

In this way, a new game that can be performed by using the inter-vivo contact data measuring device 10, for example, a plurality of measurement objects equipped with the inter-biological contact data measuring device 10 join hands or follow other measurements. It is possible to acquire contact data corresponding to each contact style while enjoying a game of touching an object.
[Configuration of Biological Contact Data Measuring Device 10]
FIG. 6A is a block diagram illustrating a configuration of the inter-body contact data measurement device 10. As shown in FIG. 6A, the inter-body contact data measurement device 10 includes a light emitting member (LED) 50, a control device 60, an acceleration sensor 62, a memory 70, a speaker 80, an output unit 90, and a battery 190. And have.
The control device 60 includes a control circuit 100, a switching timing setting unit 110, a transmission / reception switching unit 120, a transmission unit 130, a frequency modulation unit 140, a reception unit 150, a frequency demodulation unit 160, and a reception level measurement unit 162. A distance measuring unit 164, a light adjusting unit 170, and a sound adjusting unit 180. The control device 60 may be provided in the measurement unit 40 of the inter-body contact data measurement device 10, or provided separately from the measurement unit 40 when it is desired to reduce the device mass applied to the wrist, for example, It is good also as a structure hold | maintained at the pocket of clothes, a waist belt, etc.

  The acceleration sensor 62 is provided on the wearing belt 30 and measures acceleration data when the measurement subject moves his / her hand to contact another measurement subject. For example, when the measurement subject slowly performs an action to contact another measurement subject, or when touching while running, or when the hand is greatly extended, the acceleration data for each operation is measured in advance. And register it in the memory or database. Thereby, it is possible to compare the measured acceleration data with the registered acceleration data and estimate the movement of the measurer more accurately. Therefore, it is possible to accurately measure the contact mode including the angle and movement when each measurement object comes into contact based on the acceleration data obtained by the acceleration sensor, and the reliability of the measurement data can be further improved. become.

The memory (storage means) 70 transmits / receives identification data, records contact mode data, and measures each distance from the contacted inter-body contact data measuring device 10 and the previously input control program. The identification data of the person to be measured, the identification data received from the other inter-body contact data measurement device 10, the number of times of contact, the date and time of contact, the signal level (reception intensity), etc. are stored in time series.
When the speaker 80 receives the identification data received from the other inter-body contact data measurement device 10, the speaker 80 emits an arbitrary sound and notifies the measurement subject.

  The output unit 90 includes contact data stored in the memory 70 in the external control device (identification data received from another inter-body contact data measurement device 10, contact mode data, number of contacts, contact date and time, signal level (reception intensity). , Acceleration data, etc.) are transmitted by wired communication or wireless communication. Note that the output unit 90 can be connected to the electrode 20 to cause the external control device 200 to transmit contact data using human body communication.

  The control circuit 100 includes a CPU (Central Processing Unit) that executes each control program stored in the memory 70.

  The switching timing setting unit (switching timing setting means) 110 performs any time since the signal propagation path between the inter-biological contact data measurement device 10 is used for both transmission and reception when performing inter-biological communication. Switch between transmission mode and reception mode at intervals. As shown in FIG. 6B, for example, the durations t1 and t2 of each transmission mode and reception mode of the measurement subjects N1 and N2 are randomly changed. In FIG. 6B, the transmission / reception state is indicated by broken-line arrows.

  As a transmission / reception switching timing setting method, for example, the transmission mode is set to t1 = 15 msec, the next reception mode is set to t2 = 40 msec, the next transmission mode is set to t1 = 20 msec, and the next reception mode is set. A different time interval is set at random, such as setting t2 = 35 msec. In addition, since it is possible to set arbitrary time intervals as the time intervals of each mode, the measurement results of the contact data are made more finely by increasing each time interval to an arbitrary n stage registered in advance. It can be stored as data.

  As described above, in the switching timing setting unit 110, the time interval between the transmission mode and the reception mode is changed over time so that the communication modes of the pair of living body contact data measurement devices 10 do not become the same by randomly switching different time intervals. Is shifted. Therefore, in the pair of living body contact data measurement devices 10, even if the communication mode is temporarily the same in the transmission mode or the reception mode, one of the transmission modes and the other in the reception mode or one with a short waiting time. The reception mode and the other mode become the transmission mode, enabling bidirectional transmission / reception.

  The transmission / reception switching unit (transmission / reception switching unit) 120 switches to the transmission mode or the reception mode at the time interval set by the switching timing setting unit 110.

  The transmission unit (transmission unit) 130 transmits identification data (ID) stored in advance in the memory 70 to the electrode 20. Further, in the case where the receiving unit 150 receives other identification data due to contact between the measurement subjects, the transmitting unit 130 transmits the identification data and the other identification data received by the receiving unit 150 together. The contact partner's inter-body contact data measurement device 10 is informed that the contact partner's identification data has been received.

The frequency modulation unit 140 uses the fact that the distance propagating through the human body varies depending on the frequency, so that the frequency of the identification data transmitted from the transmission unit 130 is measured in order to measure the distance to the contacted living body contact data measurement device 10. Is automatically modulated in a range of 5 MHz to 10 MHz, for example. Note that the propagation distance of identification data propagating through the human body is longer when the frequency is 10 MHz than when the frequency is 5 MHz, for example. Therefore, by measuring the relationship between the frequency propagating through the human body and the propagation distance in advance, the distance from the transmission side to the reception side corresponding to the transmitted / received frequency can be obtained. Of course, the frequency range is not limited to 5 MHz to 10 MHz.
The receiving unit 150 receives the identification data transmitted from the contacted living body contact data measuring device 10 via the electrode 20.

  Since the frequency of the identification data received by the receiving unit 150 is modulated, the frequency demodulator 160 demodulates the received identification data to the original frequency.

The reception level measurement unit 162 measures the reception level (reception strength) of the identification data demodulated through the frequency demodulation unit 160. Since the reception level of the identification data measured by the reception level measuring unit 162 is a numerical value determined by the impedance characteristic of the human body, it can be used as a parameter for determining the contact mode.
The distance measuring unit (distance measuring means) 164 receives the identification data returned from the contacted living body contact data measuring device 10 out of the frequencies modulated by the frequency modulating unit 140, thereby adjusting the frequency. Measure the distance based on.

  When receiving the other identification data, the light adjusting unit 170 causes the light emitting member 50 to emit light, and adjusts the light emission intensity and the lighting pattern of light emission / extinction. The light adjusting unit 170, for example, gradually increases the light emission intensity at the beginning of light emission by mutual contact and brightens it, and turns off the light emission intensity by gradually decreasing the light emission by stopping the contact. Further, after a predetermined time elapses after the contact, the emission color may be changed to an intermediate color with the emission color of the contact partner, and the emission intensity may be gradually reduced by turning off the contact to turn off the light.

  The sound adjustment unit 180 generates a predetermined arbitrary sound from the speaker 80 when other identification data is received. The sound adjustment unit 180 can also be set so that different sounds or scales are made different according to the number of times of contact or the reception level of the identification data.

The battery 190 is a rechargeable battery and is charged when not in use.
[Configuration of External Control Device 200]
The external control device 200 analyzes the contact data provided from the plurality of living body contact data measuring devices 10 and configures the living body contact data measuring system together with the plurality of living body contact data measuring devices 10. In addition, the external control device 200 can be held by a person to be measured when a portable terminal device is used, or when a personal computer is used, a large number of inter-body contacts of 10 or more people It is also possible to measure a large amount of contact data at the same time by being connected to the data measuring apparatus 10 via a communication network.

As illustrated in FIG. 7, the external control device 200 includes a control unit 210, an input unit 220, a first database 230, an analysis unit 240, a second database 250, and a display device 260.
The control unit 210 stores contact data in the first database 230 such as identification data, distance data, and contact mode data input to the input unit 220 from the plurality of inter-body contact data measurement devices 10. The analysis unit (analyzing means) 240 performs the analysis processing of each contact data on the identification data, the distance data, the contact style data, etc. stored in the first database 230 and stores the analysis results in the second database 250. To do. That is, the analysis unit 240 analyzes each piece of contact data for each of a plurality of pieces of identification data stored in the first database 230, and the number of times of contact, the reception level of other pieces of identification data, and / or acceleration data included in each piece of contact data. The contact mode indicating the contact method between the measurement object and another measurement object according to the condition is analyzed.

The control unit 210 displays each contact data and analysis result stored in the first database 230 and the second database 250 on the display device 260. The observer can examine a guidance method or a treatment method for each measurement target person from the analysis result displayed on the display device 260.
[Control processing of contact data measurement]
FIG. 8 is a flowchart for explaining control processing for contact data measurement by the inter-body contact data measurement device 10. The control device 60 of the inter-vivo contact data measuring device 10 performs a setting process of the switching timing between the transmission mode and the receiving mode in S11 of FIG. 8 (switching timing setting means). The transmission / reception switching timing is appropriately changed by setting the above-described transmission continuation mode time t1 and reception mode time t2 to arbitrary times. For example, a plurality of time data such as time intervals T1 = 15 msec, T2 = 20 msec,... Tn = X msec are registered in advance, and the continuous mode time t1 and the reception mode time t2 are any of T1 to Tn. The switching timing is appropriately changed by randomly selecting.

  In next S12, when the preset switching timing is reached, the transmission mode is switched to the reception mode, or the reception mode is switched to the transmission mode (transmission / reception switching means).

  Subsequently, in S13, it is checked whether or not the current communication mode is the transmission mode. If it is the transmission mode (YES), the process proceeds to S14. In S14, the frequency of the identification data transmitted from the transmission unit 30 is automatically modulated in the range of 5 MHz to 10 MHz (frequency modulation means). That is, since the distance that the human body (or animal) propagates differs depending on the frequency of the identification data, the frequency of the identification data is appropriately set in order to change the distance until the identification data reaches the counterpart inter-body contact data measurement device 10. Modulate.

  In the next S15, the transmission unit 30 transmits the modulated frequency identification data. Thereby, for example, when the measurement subject's hand is in contact with another measurement subject's hand (see FIGS. 3A to 3D), the identification data propagated between the human bodies is between the measurement subject's living bodies. The data is received by the contact data measuring device 10.

  In S16, it is checked whether or not the transmission mode has ended. If the transmission mode has not ended (in the case of NO), the process of transmitting the identification data in S15 is repeated. In S16, when the transmission mode is completed (in the case of YES), the current process is terminated and the process returns to S11.

In S13, if the current transmission mode is the reception mode (NO), the process proceeds to S17 to check whether the reception unit 150 has received the identification data. In S17, when the identification data is received by the receiving unit 150 (in the case of YES), the process proceeds to S18 to check whether or not the received identification data is the identification data of the measurement subject.
In S18, when the received identification data is the identification data of the subject to be measured (in the case of YES), the process proceeds to S19, and the distance L from the frequency of the identification data to the contacted inter-body contact data measuring device 10 is detected. (See FIG. 1) is calculated, and the calculation results are stored in the memory 70 in time series (distance measuring means). Thereafter, the current process is terminated and the process returns to S11.

  In S18, if the received identification data is the identification data of another measurement subject (NO), the process proceeds to S20, and the received identification data is read and stored in the memory 70 as time-series contact data. Memorize in time series. In S20, the number of contacts, distance data, and acceleration data measured by the acceleration sensor 62 are stored in the memory 70 in time series as contact data together with the identification data.

  Subsequently, in S21, the reception level (reception strength) of the received identification data is determined, and the determination result is stored in the memory 70 in time series (reception level measuring means). As will be described later, the external control device 200 can determine the contact pattern (see FIGS. 3A to 3D) based on the determination result of the reception level.

  Then, the process proceeds to S22, in which the light emission intensity and color of the light emitting member 50 and the lighting pattern of light emission / extinction are adjusted according to the reception level. As the adjustment values of the light emission intensity, light emission color, and light emission / extinction lighting pattern of the light emitting member 50, adjustment values corresponding to the reception level are registered in advance in the memory 70. The adjustment value of the pattern and the emission color is extracted and output to the light emitting member 50.

In the next S23, the type and volume of the sound emitted from the speaker 80 are adjusted according to the reception level. As the adjustment values of the sound type and the sound volume, adjustment values corresponding to the reception levels are registered in the memory 70 in advance, and the light emission member 50 is extracted by extracting the light emission intensity and light emission color adjustment values corresponding to the light reception level from the memory 70. Output to. Then, the process proceeds to S24, where it is checked whether or not a predetermined time (any one of the time intervals T1 to Tn) for which the reception mode is set has elapsed, and when the predetermined time has not elapsed (in the case of NO). Returning to S17, the processes after S17 are performed. In S24, when a predetermined time (any one of time intervals T1 to Tn) in the reception mode has elapsed (in the case of YES), the current process is terminated and the process returns to S11.
[Contact data output interrupt processing]
FIG. 9 is a flowchart for explaining contact data output interruption processing in the inter-body contact data measuring apparatus 10. In S31 of FIG. 9, it is checked whether or not the contact data request signal stored in the memory 70 is input from the external control device 200. If the data request signal is input (in the case of YES), the process proceeds to S32. Then, each contact data (identification data, reception level, number of contacts, distance data, acceleration data, etc.) stored in the memory 70 is transmitted from the output unit 90 to the external control device 200 by wire or wirelessly. Note that the output unit 90 can also cause the external control device 200 to transmit contact data using human body communication.

In the next S33, it is checked whether or not the memory 70 is to be reset. If there is a reset instruction (in the case of YES), the process proceeds to S34, and each contact data stored in the memory 70 is erased. If there is no reset instruction in S33 (NO), the process in S34 is omitted.
[Control processing of external control device 200]
FIG. 10 is a flowchart for explaining the control process of the external control device 200. As illustrated in FIG. 10, the external control device 200 transmits a data request signal for requesting transfer of contact data to the plurality of inter-body contact data measurement devices 10 attached to each measurement subject in S <b> 41.

  In the next S42, it is checked whether or not a predetermined standby time has elapsed, and a data request is made in S41 until the predetermined standby time elapses. Subsequently, in S42, when a predetermined standby time has elapsed (in the case of YES), the process proceeds to S43, and it is checked whether or not contact data has been input from all the designated inter-body contact data measurement devices 10. In S43, when contact data is not input from all the specified inter-body contact data measuring devices 10 (in the case of NO), the process returns to S41, and the inter-body contact data measuring device 10 that has not yet transmitted data. A data request signal for requesting transfer of contact data is transmitted.

  In S43, when contact data is input from all the living body contact data measuring devices 10 (in the case of YES), the process proceeds to S44, and the contact data (identification data, Reception level, number of contacts, distance data, acceleration data, etc.) are stored in the first database 230.

  Subsequently, the process proceeds to S45, and the contact data (identification data, reception level, number of contacts, distance data, acceleration data, etc.) stored in the first database 230 is analyzed (analyzing means). That is, in S45, the contact mode indicating the contact method between the measurement object and the other measurement object according to the number of times of contact included in each contact data, the reception level of other identification data and / or the acceleration data is analyzed. Determine the contact style of the person being measured.

In this contact data analysis process, contact patterns (FIGS. 3A to 3D) are determined using impedance characteristics of the human body, and distance data is measured by high-frequency frequency modulation. It becomes possible to accurately determine the style. Furthermore, since the analysis result includes acceleration data, the observer can also know the operation speed of each measurement subject, and can more accurately observe the behavioral characteristics of each measurement subject along with the number of contacts.
In the next S46, the analysis result (contact mode, number of times of contact, distance data, acceleration data) is stored in the second database 250. Subsequently, the process proceeds to S47, and the analysis result is displayed on the display device 260. Thus, since the analysis result of each measurement subject is displayed on the display device 260, the observer can understand the behavior of each measurement subject from the analysis result, and in particular, the analysis result (contact mode, number of contacts, distance data, acceleration) By quantifying (data), it is possible to accurately grasp the personality of each measurement subject and its changes.

  In the next S48, it is checked whether or not the contact data transferred from all the specified inter-body contact data measurement devices 10 has been analyzed, and when some of the contact data has not been analyzed (in the case of NO) ), The process returns to S44, and the processes of S44 to S48 are repeated.

  In S48, when the analysis of the contact data transferred from all the inter-body contact data measuring devices 10 is completed, the process proceeds to S49, and the mesh network MN formed by each inter-body contact data measuring device 10 based on the analysis result. A schematic diagram (see FIG. 5E) is created. Subsequently, in S50, the schematic diagram data of the mesh network MN is stored in the second database 250, and the schematic diagram of the mesh network MN is displayed on the display device 260.

  The observer can understand the overall movements of a plurality of measurement subjects from the movements of each person in the schematic diagram of the mesh network MN displayed on the display device 260, and the individuality of each measurement person (for example, fast movement, slow movement) , Teamwork, leadership, collaboration, etc.) can be visually checked.

  In the above-described embodiment, a case has been described in which the inter-body contact data measurement device 10 is attached to a plurality of measurement subjects, and the contact mode, the number of times of contact, and the acceleration associated with the actions of each measurement subject are measured. For example, when performing sports such as sumo, wrestling, judo, soccer, and rugby, it is possible to measure the contact style and the number of times of contact of each player.
