Description

  The present invention relates to, for example, a controller capable of detecting biometric information used in a home game machine, and a home game machine main body (system main body) using such a controller.

  Conventionally, a controller capable of detecting biological information assumed to be used in a home game machine has been considered as shown in FIG. In FIG. 16, the controller 101 includes operation keys 111, 112, 113 a to 113 d, 114 on which an input operation is performed by the user, operation signal generation means 122 that outputs an operation number of the operation key, a signal line, a power line, and the like.

JP 2004-78634 A

  However, recently, a controller form in which a motion sensor is mounted on a controller and a user moves his / her body while holding the controller to input his / her will to the game machine has become mainstream. In the case of such a controller, the controller 101 shown in FIG. 16 is placed on the electrode of the psychosomatic function measuring means (for example, the body fat percentage meter 108) while the user moves the body while holding the controller. The hand that has been removed is easily removed, making it impossible to detect biological information. In addition, since the way the controller is held varies between left-handed and right-handed people, the surface area of the controller that comes in contact with the hand / finger differs between left-handed and right-handed people. Therefore, it becomes necessary to arrange a large number of psychosomatic function measuring means electrodes on the surface of the controller.

  Therefore, the controller of the present application aims to detect biological information stably with a simple structure.

  In order to achieve this object, the controller of the present application is a controller main body that is used by being held by hand, a first strap that is used while being held by the body, and that is connected to the controller main body. A biological information processing unit disposed on one strap and a first biological information detection unit disposed on the first strap, wherein the first biological information detection unit and the biological information processing unit are disposed on the first strap. It is electrically connected via the first signal line.

  With the above configuration, the controller of the present application has the first strap that is used while being held on the user's body (for example, wrist or upper arm), so that the user holds the controller by hand and swings the controller. For example, since the first strap is fixed to the user's wrist, the first biological information detection unit disposed on the first strap can be easily moved from the user's body (for example, the wrist or the upper arm). I will not leave. For this reason, even if the user holds the controller by hand and performs an operation of swinging the controller, it is possible to detect biological information relatively stably.

(Embodiment 1)
Hereinafter, the controller of the present invention according to Embodiment 1 will be described with reference to FIG. 1 (A) and FIG. 1 (B).

  As shown in FIG. 1A, the controller 1 includes a controller body 2, a first signal line 5 connected to the controller body 2, and a first strap 3 connected to the first signal line 5. Yes. The first biological information detection unit 4 is disposed on the first strap 3, and the biological information detected by the first biological information detection unit 4 is input to the biological information processing unit 6 via the first signal line 5. . Therefore, the first biological information detection unit 4, the first signal line 5, and the biological information processing unit 6 are electrically connected.

  A use state of the controller 1 will be described with reference to FIG. The first strap 3 connected to the controller 1 via the first signal line 5 is used while being held on a part of the body. For example, the first strap 3 may be wound around the neck and held, or may be wound around the chest, abdomen, legs or the like. Further, as shown in FIG. 1B, the controller main body 2 can be held and used on the wrist of the hand. Hereinafter, the case where the controller 1 is used in the state shown in FIG.

  A first biological information detection unit 4 is disposed on the first strap 3 that is used while being held by a human body, and the biological information is detected by the first biological information detection unit 4. The biometric information to be detected is a measurement target if it relates to biometric information such as pulse, heartbeat, body temperature, pulse wave, breathing state, sweating state, blood pressure, blood saturated oxygen concentration, myoelectricity and the like. Hereinafter, for convenience, it is assumed that the detected biological information is a pulse signal.

  The pulse signal (pulse wave waveform) measured by the first biological information detection unit 4 is input to the biological information processing unit 6 via the first signal line 5. The biological information processing unit 6 analyzes the input biological information and extracts vital data such as the pulse rate and body temperature. In the present embodiment, the biological information processing unit 6 analyzes an input pulse signal (pulse wave waveform) and derives vital data such as a pulse rate. The first biological information detection unit 4 and the biological information processing unit 6 may be configured to be supplied with power from the power supply device in the controller main body 2 via the first signal line 5 or the like. The first biological information detection unit 4 receives a command (control signal) from the biological information processing unit 6 and performs a biological information detection operation.

  The vital data extracted in the biological information processing unit 6 is wirelessly transmitted from a wireless unit (not shown) arranged in the controller body 2 to a game machine body (system body, not shown), and the game machine body (system body) (Not shown) reflects the vital data obtained from the controller 1 in the game content and improves the entertainment of the game.

  In the controller 1 of the present application, since the first biological information detection unit 4 is arranged on the first strap 3 that is held in close contact with the body, the user holds the controller 1 by hand and swings the controller 1 Even if the operation is performed, since the first strap 3 is fixed to the wrist of the user, the first biological information detection unit 4 disposed on the first strap 3 is not easily separated from the wrist of the user. For this reason, even if the user holds the controller 1 by hand and swings the controller 1, it is possible to detect biometric information relatively stably. In addition, since biological information can be detected regardless of the dominant hand, there is no need to arrange a large number of electrodes for detecting biological information on the surface of the controller body 2, and it can be held with either the right hand or the left hand. In addition, the biological information can be detected.

  2A and 2B, the biological information processing unit 6 may be mounted on a substrate 20 disposed inside the controller main body 2. As a result, the manufacture of the controller 1 is facilitated and an inexpensive controller can be realized.

  3A and 3B, the biological information processing unit 6 may be disposed on the first strap 3. Thereby, it can avoid that the biological signal detected in the 1st biological information detection part 4 attenuate | damps during transmission of the 1st signal line 5 grade | etc., Or noise mixes.

  A motion sensor (not shown) may be arranged in the controller main body 2. In this case, a motion sensor (not shown) arranged in the controller main body 2 detects an operation amount when the user holding the controller 1 spatially moves the controller main body 2 and uses the detected operation amount as a wireless unit. A person's movement is reflected in the game by wireless transmission from a game machine main body (system main body, not shown) from (not shown). In this case, the controller main body 2 is expected to be spatially swung while being held by the user's hand, and there is a risk that the controller main body may fly far from the user's hand due to carelessness of the user. However, the controller 1 of the present invention has the first strap 3 connected to the controller main body 2 via the first signal line 5, and the first strap 3 is fixed to the user's body. Even if the controller main body 2 is mistakenly removed from the hand while swinging and using the controller 1, it is possible to prevent an accident that the controller main body 2 flies far away, which is safe.

  Furthermore, the case where the 1st strap 3 is being fixed to the wrist different from the hand holding the controller main body 2 as shown in FIG. 4 is demonstrated.

  In FIG. 4, the user moves the controller main body 2 incorporating a motion sensor (not shown) spatially by hand, detects the direction and amount of the movement with the motion sensor, and the game machine main body (system main body, A state is shown in which the game machine main body (system main body, not shown) is controlled by transmitting the detection content to (not shown). In this case, the wrist of the hand holding the controller body 2 also moves violently at the same time. On the other hand, if the first strap 3 is fixed to a wrist different from the wrist of the hand that holds the controller body 2, the movement of the hand to which the first strap 3 is fixed is slower than the hand that holds the controller body 2. The frequency and intensity of artifacts can be kept low.

  Further, a configuration in which the first motion sensor 7 is disposed in the controller main body 2 and the second motion sensor 8 is disposed in the first strap 3 will be described with reference to FIG.

  In FIG. 5, the first strap 3 is fixed to the wrist of a hand different from the hand that holds the controller main body 2. For this reason, the 1st motion sensor 7 and the 2nd motion sensor 8 can be arrange | positioned to each hand or wrist, As a result, the spatial motion of both hands can be observed simultaneously. Thereby, the detection precision of a user's operation | movement can be improved.

  Further, when the user performs an operation, body movement artifacts are likely to occur in the biological information detected by the first biological information detection unit 4 arranged on the first strap 3, but the detection is performed from the detection result of the second motion sensor 8. The influence of the body motion artifact can be reduced by estimating the body motion artifact to be performed and correcting the detection of the first biological information detection unit 4 based on the result.

  Although the wrist has been described as the part for holding the first strap, any part that can be held by the body, such as the chest, forearm, upper arm, neck, shoulder, and leg, may be used.

  In addition, a well-known thing is used as a measurement method of biological information, and in order to be advantageous to the method, the first biological information detection unit 4 is attached to the surface of the first strap 3 (when the first strap 3 is fixed to the body). The surface to be placed on the body) or the back surface (the surface that is not brought into close contact with the body when the first strap 3 is fixed to the body) may be selected.

(Embodiment 2)
Hereinafter, the controller of the present invention according to Embodiment 2 will be described with reference to FIGS. 6 (A) and 6 (B). The controller 1 illustrated in FIG. 6A further includes a second signal line 11 and a second signal line 11 that are electrically connected to the biological information processing unit 6 as illustrated in FIG. The second strap 10 is connected to the second strap 10, and the second biological information detector 9 is disposed on the second strap 10 and electrically connected to the second signal line 11.

  FIG. 6B shows an example when the controller 1 of FIG. 6A is used while being held by the body. FIG. 7 shows a block diagram of the controller 1. In the second embodiment, the first biological information detection unit 4 and the second biological information detection unit 9 will be described as detecting heartbeats by an electrocardiographic method.

  In FIG. 6B, the first strap 3 is fixed to the wrist of the hand holding the controller main body 2, and the second strap 10 is fixed to the wrist of the hand not holding the controller main body 2. The first biological information detection unit 4 and the second biological information detection unit 9 that perform pulse detection by an electrocardiographic method are often configured by electrodes made of a conductor, and silver or silver chloride having high nonpolarization property is used. These electrodes are electrically coupled to the body. Therefore, in the first biological information detection unit 4 and the second biological information detection unit 9, the electrocardiographic waveform that has propagated through the body is detected. The cardiac potential waveforms detected by the first biological information detection unit 4 and the second biological information detection unit 9 are respectively input to the biological information processing unit 6. In the biological information processing unit 6, a potential difference between both wrists is detected by the differential amplifier 21 (or instrumentation amplifier). The signal obtained by detecting the potential difference between the wrists is filtered by the filter 22 and then converted into digital information by the AD converter 23. The digital information output from the AD converter 23 is input to the CPU 24 and biometric information (for example, heart rate) is extracted, and then wirelessly transmitted to the game machine main body (system main body, not shown) via the wireless unit 25. The The biological information processing unit 6 operates by receiving a control signal from the CPU 24 that operates using the crystal oscillator 26 as a clock signal (see FIG. 7).

  FIG. 8 shows a circuit example of the differential amplifier 21. The voltage follower suppresses the influence of bioimpedance, and the amplifier at the subsequent stage differentially amplifies the potential difference between the two points. An instrumentation amplifier shown in FIG. 9 may be used instead of the differential amplifier 21. The instrumentation amplifier shown in FIG. 9 has an input impedance of 1 GΩ or more, which is sufficiently large with respect to the biological impedance, and has a large function of removing common mode noise, so that detection accuracy can be improved.

  Since the controller 1 according to Embodiment 2 performs electrocardiogram measurement in the state shown in FIG. 6B, the obtained electrocardiogram takes the difference between the potentials of two points (both wrists), and common mode noise Will be reduced. As a result, common mode noise such as commercial power supply noise that propagates through the body and is detected by the first biological information detection unit 4 or the second biological information detection unit 9 can be reduced, and the SNR of the detected biological information is improved. be able to.

  FIG. 10A shows a structure in which the ground electrode 12 is disposed on the first strap 3 in order to reduce noise such as commercial power supply noise superimposed on the first signal line 5. The controller 1 shown in FIG. 10A has a ground electrode 12 disposed on the first strap 3 in FIG. 6A and electrically connects the ground electrode 12 and the ground of the biological information processing unit 6. Except that the line 13 is added, the configuration is the same as that of the controller 1 in FIG. The use state of the controller 1 in FIG. 10A will be described with reference to FIG. In FIG. 10B, the first strap 3 is attached to the wrist of the hand holding the controller main body 2, and the second strap 10 is attached to the wrist of the hand not holding the controller main body 2. The ground electrode 12 is formed of a conductive metal plate and is electrically coupled to the body. Since the ground line 13 and the ground of the differential amplifier 21 built in the biological information processing unit 6 are electrically connected, commercial power supply noise superimposed on the first signal line 5 can be reduced. . The length of the first signal line 5 and the line length of the ground line 13 may be substantially the same, and the first signal line 5 and the ground line 13 may be arranged close to each other. As a result, the noise superimposed on the first signal line 5 and the ground line 13 can be made substantially the same. As a result, the effect of reducing the noise superimposed on the first signal line 5 in the differential amplifier 21 can be reduced. Can be improved. In FIG. 10, the ground electrode 12 is disposed on the first strap 3, but the ground electrode 12 may be disposed on the second strap 10. When the first signal line 5 and the second signal line 11 are compared, since the line length of the second signal line 11 becomes longer, commercial power supply noise or the like is likely to be superimposed. For this reason, the ground electrode 12 is provided on the second strap 10 side, and the ground line 13 is electrically connected to the ground of the biological information processing unit 6, so that the differential amplifier 21 is superimposed on the second signal line 11. Noise can be reduced. Furthermore, the second signal line 11 and the ground line 13 may have substantially the same line length, and the second signal line 11 and the ground line 13 may be arranged close to each other. As a result, the noise superimposed on the second signal line 11 and the ground line 13 can be made substantially the same. As a result, the effect of reducing the noise superimposed on the second signal line 11 in the differential amplifier 21 can be reduced. Can be improved. Further, when the controller main body 2 is not electrically connected to the ground, there is no danger of current flowing through the human body, and the detection accuracy can be improved with a simple configuration.

  Further, in order to reduce noise, the controller 1 shown in FIG. 10A has a ground electrode 12 disposed on the first strap 3 in FIG. A ground line 13 for electrically connecting the output of a DRL (Digital Right Leg) circuit may be added (otherwise, the configuration is the same as that of the controller 1 in FIG. 6A). A circuit diagram and a block diagram are shown in FIGS. Detection potentials in the first biological information detection unit 4 and the second biological information detection unit 9 are input to the differential amplifier 21 via the first signal line 5 and the second signal line 11, respectively. These potential differences are detected. While the cardiac potential waveform is detected at around 1 mV, commercial power supply noise is detected at a potential of several volts, although it depends on the surrounding environment. Furthermore, the contact impedance between the first biological information detection unit 4 and the body and the contact impedance between the second biological information detection unit 9 and the body are both several hundred kΩ, and the values are independent in time. And fluctuate. The common-mode signal rejection ratio of the differential amplifier 21 needs to be at least 80 dB to 90 dB, and higher performance is required depending on the measurement environment. When the common-mode signal removal of the differential amplifier 21 is not sufficient, commercial power supply noise cannot be ignored and the SNR deteriorates. In order to solve this problem, a DRL circuit was conceived. A common mode voltage between two points is detected at the input terminal portion of the differential amplifier 21, and a common mode voltage of opposite phase is detected by an inverting amplifier. 13 is supplied from the ground electrode 12 to the human body. By applying this voltage to the human body, commercial power supply noise can be canceled, and common mode noise output from the differential amplifier 21 can be reduced.

  Furthermore, as shown in FIG. 13, the second motion sensor 8 may be disposed on the second strap 10. Thereby, the movement of the hand to which the second strap 10 is fixed can be detected, and the information is wirelessly arranged in the controller body 2 via the second signal line 11 and the biological information processing unit 6 and the like. The game machine main body (system main body, not shown) can be controlled by wireless transmission from a unit (not shown) to the game machine main body (system main body, not shown).

  In the second strap 10, the biological information can be detected simultaneously from the biological information detection unit 9 and the body movement can be detected simultaneously from the second motion sensor 8. Here, body motion artifacts due to body movements occur in the detected biological information. However, by using the second motion sensor 8, the influence of body motion artifacts can be reduced, and biological information can be detected with high accuracy. be able to.

  In the detection of the heartbeat, the fixed part of the first biological information detection unit 4 and the second biological information detection unit 9 may be any part that can be held by the body, such as the chest, forearm, upper arm, neck, shoulder, and leg, and the right wrist It is not limited to the combination of the left wrist and the right wrist / left upper arm, right wrist / left leg, right shoulder / left forearm, etc.

  6 to 13, the biometric information processing unit 6 of the controller 1 has been described as being arranged outside the controller main body 2, but the biometric information processing unit 6 may be arranged inside the controller main body 2. good. Thereby, the structure of the controller 1 can be simplified and manufacturing efficiency can be improved.

(Embodiment 3)
Hereinafter, the controller of the present invention according to Embodiment 3 will be described with reference to FIGS. 14 (A), (B), and (C). The controller according to the third embodiment includes, in addition to the controller 1 shown in FIG. 1A, a fixed band 14 (see FIG. 14A), a second biological information detection unit 9 arranged in the fixed band 14, and The second signal line 11 having one end electrically connected to the second biological information detection unit 9 and the other end electrically connected to the differential amplifier in the biological information processing unit 6 is added. Have.

  As shown in FIG. 14C, the first strap 3 is held on the wrist different from the wrist that holds the controller main body 2. The fixing band 14 has a certain width, has flexibility, and is fixed by being wound around a portion held by the hand of the controller body 2 as shown in FIG. 14B (FIG. 14C). Then, the fixed band 14 is arranged at a position slightly deviated from the part grasped by the hand, but for convenience of illustration, it is simply described as such, and ideally, It is wrapped around the part touched by the palm and fixed.) As a fixing method, for example, it is conceivable to use Velcro (registered trademark) or the like. Since the second biological information detection unit 9 having flexibility is arranged in the fixed band 14, if the hand is held so as to wrap the fixed band 14 as shown in FIG. The detection unit 9 comes close to and is electrically coupled as a result. In order to increase the degree of electrical coupling, the second biological information detection unit 9 may be arranged on the side of the fixed band 14 that does not face the controller body 2. When detecting electrocardiogram as biological information, the material of the fixed band may be realized by a flexible conductive cloth, and the conductive cloth itself may be used as the second biological information detection unit 9. Furthermore, if the length of the second biological information detection unit 9 is made longer than the outer periphery of the controller main body 2, the second biological information detection unit 9 is placed on the entire outer periphery of the controller main body 2 when the controller main body 2 is wound and fixed. Even when the user swings and uses the controller main body 2, the user's hand can be completely prevented from moving away from the electrode of the biological information detection unit, and the measurement accuracy can be improved.

  When the controller 1 according to the third embodiment is used by the method shown in FIG. 14C, the potential of the hand gripping the controller body 2 and the potential of the wrist of the hand not gripping the controller body 2 can be detected. By deriving the potential difference between these potentials with the differential amplifier of the biological information processing unit 6, it is possible to accurately detect the user's cardiac potential waveform.

(Embodiment 4)
Hereinafter, the controller of the present invention according to Embodiment 4 will be described with reference to FIGS. The controller according to Embodiment 4 further arranges a second biological information detection unit 9 on the first strap 3 of the controller 1 in FIG. 1A (see FIG. 15A) to detect the second biological information. The unit 9 and the differential amplifier in the biological information processing unit 6 are electrically connected via the second signal line 11.

  In FIG. 15A, the first strap 3 is made of a material having a certain width with flexibility, and the first biological information detection unit 4 is disposed on one surface side of the first strap 3 and the second biological information. The detection unit 9 is disposed on the other surface side of the first strap 3.

  The usage method of the controller 1 which concerns on Embodiment 4 is shown using FIG. 15 (B). The first strap 3 is attached to the wrist of the hand holding the controller body 2. A living body information detection unit (FIG. 15 (FIG. 15 (A))) is arranged on the surface side (the side not in contact with the body) of the first strap 3 wound around the wrist with the fingers of the hand not gripping the controller body 2. In B), the second biological information detection unit 9) is touched. As a result, the potential of the wrist of the hand holding the controller body 2 and the potential of the finger of the hand not holding the controller body 2 can be detected, and these potentials can be detected in the differential amplifier of the biological information processing unit 6. Since the potential difference can be calculated, it is possible to accurately detect the user's electrocardiographic waveform.

  In addition, when a user plays a game with intense body movement, such as swinging the controller body 2, the proximity state between the first biological information detection unit 4 and the second biological information detection unit 9 and the body varies greatly. It is assumed that the baseline level of the potential waveform output fluctuates and the heartbeat waveform fluctuates greatly. To alleviate this, the biological information system using the controller 1 according to the first to fourth embodiments receives a biological information obtained by the biological information processing unit 6 from the controller 1 (system main body, not shown). And a display unit (not shown) such as a television connected to a game machine main body (system main body, not shown), and the game machine main body (system main body, not shown) A system configuration may be adopted in which a predetermined operation instruction is issued to a user holding the controller main body 2 via (not shown). The predetermined operation content instructed to the user by the game machine main body (system main body, not shown) is to encourage the user's operation to be slow. Specifically, the game machine main body (system main body, not shown) , Let them take a static action for a few seconds, or make them stand upright and immobile. Thereby, a user's operation | movement condition becomes slow and the situation (situation with few generation | occurrence | production of a body movement artifact) with a high detection accuracy of biometric information can be made. After the game machine main body (system main body, not shown) issues a predetermined operation instruction to the user holding the controller main body 2 via the display unit (not shown), the first biological information detection unit 4 and When the game machine main body (system main body, not shown) receives the biometric information detected by the second biometric information detection unit 9 from the controller 1, a biometric information system capable of obtaining highly accurate biometric information can be realized. .

  Note that a predetermined operation instructed by a game machine main body (system main body, not shown) to the user holding the controller main body 2 via a display unit (not shown) is the posture shown in FIG. There may be. As a result, the posture of the user becomes the posture shown in FIG. 15B in which body movement artifacts are unlikely to occur, and the intense motion of the user can be suppressed.

  Thus, the detection accuracy of biological information can be improved by sending an instruction to the user from the game machine main body (system main body, not shown) during a game with low measurement accuracy of biological information.

  The controller in the present application is a device for operating the system or a module that controls the operation.

  Although not shown for convenience in the drawings of the present application, the ground of the biological information processing unit 6 and the ground disposed on the board built in the controller main body 2 are electrically connected, and the same in terms of DC. It is a potential.

  As described above, since the controller capable of detecting biological information according to the present invention can detect biological information relatively stably even when the user uses the body while moving, the biological information obtained from the controller. Can be used, for example, to expand the software range of game machines and improve the entertainment properties of games and the like.
