[Prior art]
In recent years, the demand for comfort and healing has increased due to the effects of various stresses, and so-called healing music and images have been demanded. Normally, human breathing, pulse, brain waves, and the like have a rhythm, and when given a specific rhythm from the outside, there is a tendency to tune to it. By utilizing such characteristics, a relaxed rhythm of 70 to 80 per minute, which is a pulse at rest, is given from the outside to stabilize and relax the mental state of a mentally unstable person, for example. It is possible to calm down the excitement of the audience who is excited in a game or the like. On the other hand, in amusement facilities, shopping centers, and the like, up-tempo music is played for the purpose of elevating the mood or increasing the willingness to purchase.

[0012]
[Problems to be solved by the invention]
However, in the configuration of Patent Literature 1, since an acoustic output synchronized with the biological information of the user is generated, when the user is in an extremely excited state, it leads to excessive stimulation. There is a problem that may be.
[0013]
Further, the system described in Patent Document 2 is for notifying the biological information of the subject to the outside, and for controlling the function of a device used by the subject whose measured value is determined to be abnormal. Not a system.
[0014]
Furthermore, in the configuration described in Patent Literature 3, only control is performed based on the arousal state of the driver detected during driving of the vehicle.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0022]
FIG. 1 is a functional block diagram of a biological information link system according to an embodiment of the present invention. The biological information interlocking system 1 of the present embodiment includes a device controller 2 corresponding to, for example, a game device or a vehicle control unit as a device to be controlled, and a person who uses and operates the device controller (hereinafter, referred to as a “user”). A) a detection unit 3 for detecting the biological information of P, and a control unit 4 for extracting the biological information of the user from the output signal of the detection unit 3 and generating a necessary signal for the device controller 2. .
[0023]
In the present embodiment, the device controller 2 corresponds to a game device used by the user P or a control device for a special vehicle.
[0024]
Here, the game device refers to a device which reads a program from game software separately or integrally incorporated and displays the contents of the program on the video device 21 or the audio device 22. The input device 5 such as a controller is used as the game device. Through the operation input by the user P, the game content is developed.
[0025]
In addition, the control device of the special vehicle receives an operation instruction of the input device 5 such as an operation lever or an operation button in accordance with an operation procedure promised in advance, and controls a corresponding driving device or device to perform a specific function. A thing.
[0026]
Next, details of the detection unit 3 will be described.
[0027]
The detection unit 3 includes a surface acoustic wave (SAW) element 31 and an antenna 32. The surface acoustic wave element 31 is a part that detects the biological information of the user P as a change in the propagation characteristics of the surface acoustic wave, and the antenna 32 is a part that transmits and receives radio signals. Usually, the surface acoustic wave element 31 and the antenna 32 are separately manufactured and connected to each other on a circuit board. However, the antenna 32 may be formed directly on the substrate of the surface acoustic wave element 31 and connected.
[0028]
As the antenna 32, various types of antennas such as a dipole, a monopole, a loop, a helical, a patch, and a chip can be used. When impedance matching is not sufficient for connection with the surface acoustic wave element 31, the element having the R, C, and L components is inserted and used after impedance matching.
[0029]
FIG. 2 shows a configuration example of the detection unit 3. The surface acoustic wave element 31 includes a piezoelectric substrate 33, a comb-shaped electrode 34 formed on the surface thereof, and reflectors 35, 35. The reflectors 35 are arranged at intervals so that the return signals of the surface acoustic waves propagating from the comb-shaped electrode 34 do not overlap each other, so that the return signals can be compared.
[0030]
The antenna 32 is connected to the land 36 of the comb-shaped electrode 34. This connection usually uses a wire, but it is also possible to make a direct connection via a bump by a flip chip method. When the antenna 32 is formed on the surface of the piezoelectric substrate 33, the antenna 32 may be connected by patterning when forming the comb-shaped electrode 34 and the reflector 35.
[0031]
As a material for forming the comb-shaped electrode 34 and the reflector 35, aluminum is a preferable example because of its low electric resistance, light weight, and easy patterning. In addition, copper, titanium, chromium , Gold or the like may be applied. Further, these metals may be alloyed, various metals may be added, or they may be laminated.
[0032]
Further, the material, width, and thickness of the thin film of the comb-shaped electrode 34 and the reflector 35 are adjusted so that inductance, capacitance, and the like according to the design are obtained. As the thin film forming method, in addition to the sputtering method, a vacuum thin film forming technique such as vapor deposition, a plating method, a paste printing method, and the like can be applied.
[0033]
As the piezoelectric material for the piezoelectric substrate 33, a material having a predetermined physical property coefficient according to a change in the state of the detection target is used. For example, when detecting the body temperature of the user P, it is necessary to apply a piezoelectric material having a temperature coefficient. Specifically, a 128 ° rotated Y-cut substrate made of lithium niobate single crystal is suitable. In addition, quartz, lithium tantalate, lithium tetraborate, langasite, and the like can be used as the piezoelectric material. If only the blood pressure and the pulse are to be detected, a material that is insensitive to temperature can be selected as the piezoelectric material.
[0034]
Next, the configuration of the control unit 4 will be described.
[0035]
The control unit 4 has a function as a transceiver that transmits a drive signal to the detection unit 3 and receives and analyzes a response signal from the detection unit 3. Specifically, it includes a drive signal generation circuit 41, a switch 42, an antenna 43, a reception circuit 44, a detection circuit 45, a reference signal generation circuit 46, a high-speed averaging circuit 47, and a control signal generation unit 51.
[0036]
The drive signal generation circuit 41 is a circuit that generates a drive signal for driving the surface acoustic wave element 31, and generates a pulse signal in synchronization with the reference signal generated by the reference signal generation circuit 46. The generated drive signal is transmitted to the detection unit 3 via the switch 42 and the antenna 43.
[0037]
The receiving circuit 44 is a circuit for receiving a response signal from the detection unit 3 received via the antenna 43 and the switch 42. The receiving circuit 44 includes a band-pass filter for eliminating unnecessary radio waves and a level capable of processing the received signal. And a low-noise amplifier for amplification.
[0038]
When the phase detection method or the delay time detection method is applied to the detection of the change in the propagation characteristics of the surface acoustic wave, the detection circuit 45 is provided between the signals reflected by the plurality of reflectors 35 or at the reflector 35. This is a portion for detecting a phase difference and a delay difference between the reflected signal and the reflected signal reflected by the mismatching from the comb-shaped electrode. Further, when the frequency detection method is applied to the detection of a change in the propagation characteristic of the surface acoustic wave, this is a portion for detecting a frequency difference between signals reflected by a plurality of reflectors.
[0039]
The high-speed averaging circuit 47 is a part that performs signal addition processing several hundreds to tens of thousands times and extracts necessary information from a signal buried in noise.
[0040]
The control signal generation unit 51 is a circuit that generates a specific signal prepared for the device controller 2 (for example, a control device of a game machine or a special vehicle) from the extracted biological information. , A storage unit 49, and a determination unit 50.
[0041]
The storage unit 49 stores one or a plurality of pieces of biological information (blood pressure, pulse rate, body temperature, and the like) of the user P in a normal state, and uses this as reference data until the biological information changes to an abnormal level. Threshold is set.
[0042]
The human body has a biological rhythm for a period of 24 hours or longer, and varies depending on the state of health. Therefore, it is preferable to acquire reference data in a quiet state in advance. In this case, since the biological information is different depending on the measurement unit and the measurement method, it is preferable that the detection unit 3 is attached to the same part when the reference data is collected and when the reference data is used. It is performed in consideration of.
[0043]
The evaluation threshold value is for evaluating the degree of excitement of the user P from the detected biological information of the user P, and for causing the device controller 2 to perform different control in accordance with each threshold level. The control content is stored in advance in association with the threshold level.
[0044]
The determination unit 50 is a unit that determines the magnitude relationship between the detected biological information of the user P and each of the evaluation thresholds stored in the storage unit 49, and supplies the determination result to a signal generation circuit.
[0045]
The control signal generation circuit 48 is a part that generates necessary control signals by sequentially referring to the storage unit 49 and the determination unit 50, and supplies the generated control signals to the device controller 2. The device controller 2 to which the control signal is input controls the video device 21, the audio device 22, or various driving devices and driving devices 23 of the vehicle, and realizes the control content corresponding to the control signal. This control signal generating circuit 48 corresponds to “control means” according to the present invention.
[0046]
Next, the principle of detecting biological information by the detection unit 3 and the control unit 4 configured as described above will be described.
[0047]
First, a pulse-like drive signal is generated by the drive signal generation circuit 41 of the control unit 4 and transmitted to the detection unit 3 attached to the measurement site of the user P via the antenna 43. In the detection unit 3, when a drive signal is supplied to the surface acoustic wave element 31 via the antenna 32, a surface acoustic wave having a wavelength corresponding to the electrode pitch of the comb-shaped electrode 34 is excited on the surface of the piezoelectric substrate 33. This surface acoustic wave propagates on the surface of the piezoelectric substrate 33, is reflected by the reflectors 35 and 35, and returns to the comb-shaped electrode 34. The comb-shaped electrode 34 converts the surface acoustic wave returned by the reflection into an electric signal, and returns the electric signal to the control unit 4 via the antenna 32. The control unit 4 extracts the biological information of the user P from the detection signal of the detection unit 3 received via the antenna 43 via the reception circuit 44, the detection circuit 45, and the high-speed averaging circuit 47.
[0048]
Here, when the body temperature of the user P is detected as the biological information, the fact that the propagation characteristic of the surface acoustic wave changes according to the temperature characteristic of the piezoelectric substrate 33 that senses the change in the body temperature of the user P is used. Then, for example, the phase difference between the return signals of the reflectors 35, 35 is compared. In this example, the method of detecting the biological information of the user by comparing the phases of the return signals is adopted.In addition, the method of comparing the delay time between the return signals and the method of detecting the return signal from the reference frequency are used. And a method of comparing the signal strength of the return signal and the frequency shift of the return signal.
[0049]
The blood pressure and pulse rate of the user P are detected as pressure changes in the external environment. In this case, the piezoelectric substrate 33 of the surface acoustic wave element 31 has a cantilever or double-supported beam structure, and a pressure change is detected as a change in the propagation characteristics of the surface acoustic wave due to a change in the shape of the piezoelectric substrate 33.
[0050]
When detecting biological information having a relatively small pressure change, such as pulsation, the surface acoustic wave propagation surface of the piezoelectric substrate 33 is brought into direct contact with the measurement site of the user P via a protective film, and the pulsation causes It may be used that the contact pressure of the surface acoustic wave on the propagation surface changes, and as a result, the propagation signal intensity of the surface acoustic wave changes.
[0051]
If a comb-shaped electrode is placed in the center of the piezoelectric substrate and a reflector is placed on both sides of the comb-shaped electrode, one of them can be used for temperature measurement and the other can be used for pressure measurement, then one surface acoustic wave element can be used to generate different types of biological materials. Information can be detected.
[0052]
On the other hand, as a method of detecting the respiratory rate and the expiration component of the user P, a material having a selective reaction or adsorption property to a specific substance is formed on the surface acoustic wave propagation surface of the piezoelectric substrate, and the elasticity is obtained by the reaction and adsorption. Utilize the fact that the propagation characteristics of surface waves change (see Nomura et al., "Surface Wave Humidity Sensor Using Polymer Dielectric Thin Film", IEICE Technical Report of IEICU US93-25 (1993-07)).
[0053]
For example, if a detection unit composed of a surface acoustic wave element having a hygroscopic film formed on a surface of a piezoelectric substrate on which a surface acoustic wave propagates is disposed at the mouth of the user P, the surface of the user P changes upon sensing the exhaled breath. Wave propagation characteristics can be detected.
[0054]
Further, in this example, the surface acoustic wave element 31 has only a function as a sensor, but the surface acoustic wave element may also have an ID function. Specifically, this can be realized by forming an ID reflector on the surface of the surface acoustic wave element 31 separately from the sensor reflector. Normally, a case where there is a reflection is identified as 1 and a case where there is no reflection is identified as 0, so that a maximum of 2 arrangements of N reflectors are required in order to insert N bits of information. Therefore, a method of partially arranging the reflector so as to correspond to the information or electrically controlling the reflection characteristics of the formed reflector can be applied.
[0055]
As described above, by configuring the sensor unit of the detection unit 3 with the surface acoustic wave element 31, it is possible to configure a battery-less, small-sized, and simple sensor, and to easily obtain necessary biological information. Can be.
[0056]
Next, a specific operation of the present embodiment will be described. Here, an example in which a game device is applied as the device controller 2 and an example in which a control device of a special vehicle is applied will be described.
[0057]
(First Embodiment)
3 and 4 show an example in which the present invention is applied to a game machine, and show a schematic configuration and an operation of the present invention.
[0058]
The user P uses the detection unit 3 by attaching it to the wrist. The detection unit 3 and the control unit 4 are wirelessly connected and do not hinder the movement of the user P. The control unit 4 is connected to the game machine 2, and from the game machine 2 is further connected to a video device 21 and an audio device 22 as game display means.
[0059]
In this example, the detection unit 3 is mounted on the artery of the wrist in order to detect the pulse and the body temperature of the user P. In addition to this, for example, the detection unit 2 is attached to the chest of the user P to detect a heartbeat, or attached to the armpit or the like to detect body temperature, or the detection unit 3 is attached to the mouth in a headphone type to measure the respiratory rate. You may make it detect.
[0060]
The detection result by the detection unit 3 is sent to the control unit 4 in the form of a response signal to a drive signal periodically transmitted from the control unit 4. The control unit 4 receives the signal from the detection unit 3 and performs signal processing to extract biological information (pulse, body temperature) of the user P. The extracted biological information is supplied to the control signal generator 51, and a control signal for the game machine 2 is generated.
[0061]
As shown in FIG. 1, in the control signal generation unit 51, the storage unit 49 stores the pulse rate and the body temperature of the user P in a normal state, and a plurality of evaluation thresholds set up and down based on the pulse rate and the body temperature. ing. The determination unit 50 compares the biological information of the user P detected by the detection unit 3 with the evaluation threshold, and supplies the result to the control signal generation circuit 48. The control signal generation circuit 48 generates a control signal of the control content stored in the storage unit 49 in association with the result of the determination by the determination unit 50.
[0062]
As shown in FIG. 4, in the game displayed by the game machine 2, a plurality of options (selection 1, selection 2,..., Selection M) that can be selected by the user P from the game start to the game end are prepared. Different story developments can be obtained depending on which of the options in each row is selected. There is a difference in the degree of excitement obtained by playing between the plurality of story developments, and N options are prepared by integrating biological information such as body temperature, pulse rate, and respiration rate. These options include not only changes in story development, but also changes in brightness, color, blinking, and volume of the video.
[0063]
Thereby, for example, when the control signal generation unit 51 determines that the degree of excitement of the user P increases with the progress of the game and the level of the excitement has changed to an abnormal level, the game is started by the operation input of the user P. The development is limited, and the control unit 4 automatically selects the game development so that the biological rhythm of the user P does not exceed the abnormal value or in a direction to calm the biological rhythm. Thereby, the unintended mental burden of the user P can be suppressed.
[0064]
Here, when the control of the game machine 2 by the control unit 4 is performed, if the fact is displayed to the user P, the user P can be alerted. The display may be performed before or after the control by the control unit 4. Further, as a display method, visual display via the video device 21 and / or audio announcement via the audio device 22 can be applied.
[0065]
In addition, when abnormalities such as the biological level of the user P are extremely weakened and excited to fall into an unsuitable level for health, or when the biological level fluctuates greatly, the game is forcibly terminated. (FIG. 4).
[0066]
On the other hand, from the start to the end of the game, the game can be developed based on the biological information of the user P by the control unit 4 instead of the game environment in which the game is developed by the user P.
[0067]
In this case, the control signal generator 48 compares the detected biometric information of the user P with the evaluation threshold as needed, and determines the degree of excitement of the user P based on the magnitude of the biometric information value. Then, it generates a signal of control content set in advance corresponding to the biometric information value, and supplies it to the game machine 2. The game machine 2 selects a story development based on the input control signal. Thereby, a story suitable for the biological rhythm of the user P can be developed.
[0068]
Further, in the present embodiment, a target threshold value of the biological information value is set within a range where there is no health problem so that the stimulation level or the degree of excitement set by the user P can be provided, and the target threshold value is fixed toward the target threshold value. A game mode is also provided for automatically selecting a game development in which the biological level of the user P is gradually increased with this rhythm. In this game mode, not only story development but also control modes such as brightness, color, blinking, music, sound volume, and application of vibration to the controller 5 are provided. Thereby, entertainment can be further enhanced.
[0069]
(Second embodiment)
5 and 6 show an example in which the present invention is applied to a control device of a special vehicle, and show a schematic configuration and an operation of the present invention.
[0070]
The user P wears the detection unit 3A on the wrist and uses the headphone type detection unit 3B on the head. The detection units 3A and 3B and the control unit 4 are wirelessly connected, and do not hinder the movement of the user P. The control unit 4 is connected to the control device 2 of each part of the special vehicle 10, and the control device 2 is connected to an image device 11, an audio device 12, and devices and devices (power unit, steering unit, etc.) 23 (not shown). .
[0071]
In this example, the detection unit 3A detects the pulse and the body temperature of the user P, and the detection unit 3B attached to the mouth of the user P detects the respiratory rate and the expiration component.
[0072]
The control device 2 obtains an operation instruction and biological information of the user P from the input device 5 such as a steering wheel and a lever, and the detection units 3A and 3B and the control unit 4, respectively, verifies the validity of the operation instruction, and does not illustrate. An operation signal is sent to a power unit, a steering unit, and the like, and the operation instruction, the biological information, and the result of the determination are output to the video device 11 and the audio device 12 to notify the user P.
[0073]
As shown in FIG. 1, in the control signal generation unit 51 of the control unit 4, the storage unit 49 stores the pulse rate, the body temperature, and the respiration rate of the user P in the normal state, and the evaluation threshold set based on the pulse rate, the body temperature, and the respiration rate. Are stored. In this example, the evaluation thresholds are set as evaluation thresholds from the viewpoint of “can be driven” and “can advanced operation be performed”. The determination unit 50 compares the biological information of the user P detected by the detection unit 3 with the evaluation threshold, and supplies the result to the control signal generation circuit 48. The control signal generation circuit 48 generates a control signal of the control content stored in the storage unit 49 in association with the result of the determination by the determination unit 50.
[0074]
FIG. 6 shows an example of the control flow. When driving the special vehicle P, the driver P wears the detection units 3A and 3B and inputs biological information to the control unit 4. At this time, if no abnormality is found in the detected biological information, the operation and operation by the user P are allowed as they are, and the control device 2 drives and controls the corresponding device according to the operation of the input device 5.
[0075]
On the other hand, when any one of the detected biological information exceeds the predetermined evaluation threshold and indicates an abnormal value, the control unit 4 determines that the vehicle is not in the “operable state” and supplies a control signal to the control device 2. I do. As a result, the control device 2 does not receive an operation instruction from the input device 5. Accordingly, it is possible to prevent the operation and driving of the vehicle by a person who is not qualified for driving, for example, when the user P is extremely harmful to health or is drunk.
[0076]
In addition, even during use, if a specific change in biometric information is sensed, such as suddenly feeling sick or drowsy, it is judged that "advanced operation is difficult", and the specific symptoms are addressed. To generate a control signal. Thereby, the control device 2 performs an appropriate measure such as restricting the operation instruction from the input device 5 or stopping the operation in a safe state.
[0077]
The control device 2 performs the above measures, displays and notifies the user of the result via the video device 11 and the audio device 12, and prompts the user P to pay attention and warning.
[0078]
Although the embodiments of the present invention have been described above, the present invention is, of course, not limited thereto, and various modifications can be made based on the technical idea of the present invention.
[0079]
For example, in the above-described embodiment, an example in which the control target device is applied to a control device of a game machine or a special vehicle has been described. However, the present invention is not limited thereto. For example, a video, image, graphic, music, light or sound signal , Or an object that displays an operation or is an operation target, and is generally a television, a personal computer, a PDA (Personal Digital Assistant), a monitor, a mobile phone, a business or general game machine having a display function.
