Best mode for carrying out the explanation

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A. First Embodiment

A-1. Overall Configuration of Body Motion Detection System First, FIG. 1 shows the overall configuration of the body motion detection system according to the first embodiment of the present invention. As shown in the figure, this body movement detection system is attached to a part of the human body. And a body motion management device 12 for receiving body motion information transmitted from the body motion detection device 10 via the communication network 11. . Here, the communication network 11 includes a fixed telephone network, a mobile communication network, and the like, and indicates a plurality of S base stations (not shown). Therefore, a terminal having a wireless communication function such as a mobile phone in a predetermined service area can communicate with another communication device connected to the communication network 11. In addition, the body motion detection device 1

0 is the power at which a large number of communication terminals such as mobile phones and telephones can be connected to the communication network 11. Here, for simplicity of explanation, the body motion detection device 1 Only the motion management device 12 is shown. A-2. Body Motion Detection Device Next, the configuration of the body motion detection device 10 will be described. Here, FIG. 2 is a perspective view showing an appearance of the body;] ¾ detection device m10, and FIG. 3 is a block diagram showing a configuration of the body motion detection device-10. As shown in FIG. 2, the body motion detection device 10 is composed of a body motion detection device 10 containing a body motion detection circuit and the like (see FIG. 3), which are the main part, and a housing 1. And a band portion 16 for holding the wrap 5 around the arm. In other words, the body motion detection device 10 is worn by the band portion 16 being wrapped around the arms (including wrists and fingers), feet, neck, waist, head, etc. of the living body. Is done. Among them, the body movement detecting device 1 ◦ is most preferably a wristwatch type. Usually, when a person moves, it is rare that the arm does not move, and when walking or running, the body movement of the arm increases according to the walking or running speed, etc. This is because the arm is often moved when performing the exercise. In consideration of such points, the body motion detection part can be detected by using the arm as the body motion detection part. In addition, such a wristwatch-type watch has excellent portability and reduces hindrance to body movement. In the embodiment, the body motion detection device 10 may be built in a force band 16 built in the housing 15. Since there is no influence of the movable play at the attachment part between the band 16 and the housing 15, false information at the time of body movement detection can be reduced. You can get accurate body movement information. Further, the housing 15 and the band 16 may be formed by plastic molding or the like. As shown in FIG. 3, the body motion detection device 10 includes a power waveform generation unit (power generation ^ stage) 20, a control circuit (body motion information generation means) 21, a power supply 22, and a wireless communication device. (Communication means) 23 and a display device 24, which are arranged inside the above-mentioned housing 15. The power waveform generation unit 20 has a rotating weight 25 that makes a rotation in accordance with the movement of the arm on which the body motion detection device 10 is mounted, and the rotating weight 25 causes the rotating weight to rotate. Car 26 can be turned. A high speed gear 27 for increasing rotation is engaged with the rotating spindle 26, and the rotation of the rotating weight wheel 26 accelerated by the high speed wheel 27 is applied to the disk-shaped rotor 28. To be transmitted. The rotor 28 has a permanent magnet magnetized to two or more poles. When the rotor 28 is rotated, an alternating current is applied to a stator 29 (made of a high magnetic permeability member) that houses the rotor 28. A magnetic field develops and an electromotive voltage is generated in the coil 30. In other words, when the living body to which the body movement detecting device 10 is attached moves, the rotating weights 25 and the like catch the body movement and rotate, and the alternating current is applied to the coil 30 by electromagnetic induction using the rotation. Electric power is generated. Here, the rotating weight 25 is designed to improve the body motion detection capability (improving the body motion detection capability means enabling detection of even weak body motion). Preferably, it can be larger. Therefore, the outer peripheral portion of the oscillating weight 25 is preferably thicker than the portion near the center of rotation, and it is preferable to use a heavy metal such as a pure gold / gold alloy or a tungsten alloy. Further, in order to increase the ratio of the moment of inertia to the mass, it is preferable to make a hole in the vicinity of the rotation center of the rotating weight 25 by making a hole. Also, in order to improve the body motion detection ability, it is preferable to make a hole near the rotation center of the oscillating wheel 26 and the speed increasing wheel 27 as in the case of the oscillating weight 25 to remove the thickness. Here, the power waveform generation unit 20 has the same configuration as the power generation mechanism mounted on a wristwatch or the like, but since the purpose of use is to detect the state of body movement, the output is higher than that of the type mounted on a wristwatch. May be small. Therefore, the force waveform-generating section 20 can be smaller and lighter than the power generating mechanism mounted on the clock addressed to H. In addition, the power waveform generator 20 and the control circuit 21 can be unitized, and can be incorporated into the band 16 to facilitate handling in the manufacturing process and the like. it can. Here, as the entire force waveform generator 20 becomes smaller, the air force resistance existing inside the body motion detection device 10 becomes a major obstacle, as it becomes smaller. In particular, since the rotor 28 rotates at the fastest speed, it is affected by the air viscosity resistance, and the rotor 28 receives a braking force, which hinders the improvement of the body motion detection ability. Therefore, in order to improve the body motion detection capability, it is preferable that the pressure inside the body motion detection device 10 be lower than the atmospheric pressure and as close as possible to a vacuum. Furthermore, the contour shape of the cross-sectional outer shape of the rotor 28 is preferably a streamline shape which eliminates a flat surface and has a thicker central portion and a gradually thinner outer peripheral portion. The control circuit 21 includes a waveform shaping circuit 31, a body motion information generating circuit 32, a communication control circuit 33, and a display control circuit 34. The waveform shaping circuit 31 performs a waveform shaping process on the AC power output from the coil 30 of the power waveform generating unit 20 and outputs the AC power to the body motion information generating circuit 32. Here, the waveform shaping circuit 31 performs processing required to generate body motion information described later, for example, processing such as smoothing and rectification. The body motion information generation circuit 32 generates body motion information based on the power waveform input from the power waveform generation unit 20 via the waveform shaping circuit 31. In the power waveform generator 20 described above, the power generation waveform as shown in FIG. 4 is generated in the coil 30 during the period from the rotation of the rotary weight 25 with the movement of the human body until the rotation stops. appear. Here, the rotation of the oscillating weight 25 changes according to the degree of the body movement of the human body to which the body movement detection device 10 is attached. Therefore, the power generation waveform generated in the coil 30 also depends on the degree of the body movement of the human body. Will change. In this embodiment, the degree of body movement is Various body motion information can be generated by using the power generation waveform that changes depending on the situation. Further, according to the power waveform generation unit 20, as shown in the figure, a number of waveforms can be obtained by one charter, and a gear train 27 for increasing the rotation of the rotating weight 25 is provided. Therefore, a sufficient waveform can be obtained even with a weak body motion, and even a weak body motion can be detected more accurately. The body motion information generated by the body motion information generation circuit 32 will be described later. The body motion information generated by the body motion information generation circuit 32 is sent to the communication control circuit 33 and the display control circuit 34. The communication control circuit 33 controls the transmission of the body motion information generated by the body motion information generation circuit 32 to the body motion management storage 12 (see FIG. 1). In addition, a transmission control command including a communication start timing and a transmission destination is transmitted to the wireless communication device 23. The wireless communication device 23 transmits the body motion information to the body motion management device 12 via the communication network 11 based on the transmission control command of the communication control circuit 33. The wireless communication concealment 23 has an antenna that can perform wireless transmission and reception with the base station of the communication network 11 (see Fig. 1), and has the same wireless communication function as a known mobile phone. ing. The display control circuit 34 causes the display device 24 to display the body motion information generated by the body motion information generation circuit 32. The body motion information generated by the body motion information generation circuit 32 in this manner is not only transmitted to the body motion management device 12 but also transmitted to the communication device 24 of the body motion detection device 10. However, a person who has attached the body motion detection device 10 can also check body motion information.

A-3. Body motion information Next, body motion information generated by the body motion detection device 10 having the above configuration will be described. By using the power waveform generated by the power waveform generator 20, various types of body motion information can be generated in addition to binary body motion information such as whether the body has moved or not. Hereinafter, a specific example of the body motion information generated by the body motion information generation circuit 32 will be described. As described above, the power waveform generated by the power waveform generation unit 20 changes according to the degree of body motion of the person to whom the body motion detection device 10 is attached. In other words, as the degree of body movement increases, a larger power waveform can be obtained. By taking advantage of this point, it is possible to detect whether the degree of the body movement is one of a plurality of stages and generate body movement information indicating the degree of the body movement. A specific method for generating such body motion information will be described. In this case, the power waveform obtained by the power waveform generator 20 is first subjected to full-wave rectification. As shown in Fig. 5, the power waveform obtained by full-wave rectification is compared with a plurality of reference values (two in the figure) using a comparator. Then, based on the outputs from these comparators, it is possible to generate body movement information indicating the degree of body movement in a plurality of (number of reference values to be set) levels. For example, in the case of the waveform shown in Fig. 5, the first motion of the body motion is larger than the smaller reference value and smaller than the larger reference value. Generate motion information. On the other hand, in the second body movement, since the waveform is larger than the reference value of the larger body movement, a body movement report indicating that the body movement is strong is generated. As described above, by comparing the power waveform from the power waveform generation unit 20 with a plurality of reference values, it is possible to detect the degree of body motion at a plurality of levels and generate body motion information. In addition, since the body motion level can be detected in a plurality of stages, it is possible to detect which level of body motion has been detected and how many times per predetermined time. According to the detected body motion per predetermined time, body motion information such as “walking” or “running” may be generated. At this time, if the power waveform obtained by the power waveform generator 20 is made smooth using a smoothing capacitor as shown in FIG. 6, even if the sampling time for detection in the comparator is long, However, body movement can be detected. In addition, as described above, the degree of detailed body movement can be detected at a plurality of levels. Therefore, if a table that stores the detection level of body movement and the estimated calorie consumption is stored, the body movement can be detected. It is also possible to generate energy consumption information as body motion information according to is there. At this time, the above table is provided for each use environment condition such as the temperature and the mounting position and the condition such as the age and gender of the person wearing the body motion detection device 10, and according to the condition set by the user. If a table is selected, a more accurate estimated power consumption can be obtained. The calories consumed in these tables can be determined experimentally in advance. Further, not only the body motion information indicating the degree of the body motion as described above, but also body motion information indicating the estimated body motion amount within a predetermined time can be generated. In this case, the body motion information generation circuit 32 can obtain the amount of power within a predetermined time by performing AZD conversion of the power waveform from the power waveform generation unit 20 and performing an integration operation. As described above, if a table in which the electric energy and the estimated calorie consumption are stored is provided, body motion information indicating the estimated total calorie consumption within a predetermined time can be generated. In addition, if the power waveform obtained by the power waveform generation unit 20 by 1 冋 body motion is subjected to AZD conversion and integration calculation is performed, body motion information indicating an estimated total body motion amount of one body motion can be generated. it can. Further, it is also possible to detect a maximum value of the power waveform obtained by the power waveform generation unit 20 by one body motion and generate body motion information such as a numerical value indicating a body motion amount corresponding to the maximum value. Good. Further, the body motion information generation circuit 32 may have a configuration as shown in FIG. As shown in the figure, the body motion information generation circuit 32 has a capacitor 60, and the power generated by the power waveform generation unit 20 charges the capacitor 60 via the rectification circuit 61. It is supposed to be. The voltage detection device 62 that detects the charging voltage of the capacitor 60 may detect the charging voltage value, and may generate body motion information based on the detection result. Here, an appropriate load 63 may be provided to the capacitor 60, and the capacitor 60 may be gradually discharged when not charged. By using the power generation waveform of the power waveform generation unit 2 • described above, body motion information can be generated with such a simple circuit configuration. As described above, since various body motion information can be generated by using the power generation waveform of the power waveform generation unit 20, the body motion information generation circuit 32 generates the body motion information according to the generated body motion information. The route configuration may be determined. Of course, the circuit configuration may be such that a plurality of types of charter information can be generated in parallel. A— 4. Body motion management device Returning to FIG. 1, the body motion management device i 12 includes a reception device 13 that receives body motion information transmitted from the body motion detection device 10 via the communication network 11. And a comprehension device 14 for compensating the body movement information received by the receiving device 13. Therefore, in the body movement state detection system according to the present embodiment, by looking at the display device 14, the body movement state of the person wearing the body movement detection device 10 at a remote place can be confirmed. Here, when the wireless communication device 23 (see 冈 2) performs wireless communication using the PHS (Personal Handy-phone System), the location registration control between the wireless communication device 23 and the communication network 11 is performed. In this case, if the receiving device 13 can receive the position information of the body motion detecting device 10 in addition to the body motion † g information described above, In addition, the position and the body motion state of the person wearing the rest detection device 10 can be confirmed. In addition to the PHS such as PHS that uses location registration control of a mobile communication system, an antenna for using a GPS (Global Positioning System) is provided in the body motion detection device 10, and this GPS antenna is The acquired position information of the body motion detection device 10 may be transmitted to the body motion management device 12. A-5. Modifications Note that the body motion detection device 10 in the first embodiment described above is not limited to the device including the above-described power waveform generation unit 20 but may be a device that detects a body motion using an acceleration sensor. Use a device that detects body movement with a magnetic switch, a device that detects body movement with a mechanical clutch, etc., with the same configuration as a conventionally known pedometer, etc. The body motion information may be transmitted to the body motion management device 12 Further, in the body motion detection device 10, the body motion detection device 10 itself has the wireless communication device 23 capable of communicating with the communication network 11, but is not limited thereto, and can communicate with the communication network 11 A separate relay unit is provided separately, the rest information is wirelessly transmitted from the rest detection unit HI0 to the relay unit, and the body movement is controlled from the relay unit to the body movement management and concealment unit 12 via the communication network 11. A report may be transmitted. In this way, since the body movement detection and concealment 10 only needs to have a simple wireless transmission function, the size and weight of the body movement detection device 10 can be easily reduced.

Here, the transmission unit 71 is arranged in the home 73, and the power waveform generation unit 70 is mainly used in the home 73. As shown in FIG. 9, the power waveform generation unit 70 includes a housing 85 in which a circuit unit and the like to be described later are built in, and a band unit 86 that holds the housing 85 around an arm. ing . In other words, the power waveform generation unit 70 is of a wristwatch type, and the band waveform portion 86 is wound around the arm, so that the power waveform generation unit 70 is mounted. Here, in the power waveform generation unit 70, a display device may not be provided, but a function as a clock for displaying time or the like may be provided by providing a display device. As shown in FIG. 10, a power waveform generation unit 70 includes a power waveform generation unit 20 and a waveform shaping circuit 31 similar to those in the first embodiment, and a power waveform generation unit 20 and a waveform shaping circuit 3. And a wireless transmission device 90 for wirelessly transmitting waveform information according to the power waveform supplied via the wireless communication device 1. Here, the wireless transmission device 90 is located in the same home. It transmits the waveform information to the transmitting unit 71 by radio, and may be a radio system similar to a general cordless telephone, or may be an optical communication system such as infrared rays. The transmission unit 71 has a wireless reception unit 91 that receives the waveform information wirelessly transmitted from the wireless transmission device H9 • of the power waveform generation unit 70 described above. Radio reception section 91 sends the received waveform information to transmission concealment 92. The transmitting device 92 transmits this waveform information to the body motion state detecting device 72 via the communication network 11. Here, since the transmitting unit 71 is provided separately from a moving human body, it is also an nj ability to fix the transmitting unit 71. Therefore, the transmission method from the transmission device 92 to the communication network 11 is not limited to the wireless method, but may be a wired method such as a general subscription t-speak. When a dedicated line is used, waveform information based on the power waveform of the power waveform generation unit 20 described above may be transmitted to the body movement state detection device H72 in real time. When used, the transmission device 92 or the power waveform generation unit 70 may be provided with a buffer memory for storing waveform information for a predetermined time, and the waveform information may be transmitted at predetermined time intervals. Frequently, the transmission timing may be set according to the application.

The body motion information generation device 75 has the same circuit as the body motion information generation circuit 32 of the first embodiment described above, and the power waveform transmitted from the transmission unit 71 (see FIG. 4). ), The various body motion information described above can be generated based on the waveform information corresponding to

Therefore, in the body movement state detection system according to the present embodiment, the power waveform generation unit 70 in the remote home 73 is mounted by looking at the display device 14 as in the first embodiment described above. It is possible to check the state of the body movement of the person who performed. This remote area Since the body motion state detection device 72 can detect the body motion state of a person in the home, if the state of the elderly living alone and the behavior of the elderly wandering at night as described above are confirmed, It can be applied as a welfare system. In this case, for example, if it is confirmed from the waveform information transmitted from the transmission unit 71 that there is no pause, it is understood that there is no particular problem. On the other hand, the transmission unit 7 When it is confirmed from the waveform information transmitted from 1 that the body motion has not been performed for a predetermined time on the display device 14, it can be determined that some abnormality has occurred.

Such a switch mechanism may be provided to detect whether or not the switch mechanism is mounted on / off. Further, in this body movement state detection system, the power waveform generation unit 70 performs short-range wireless transmission with the transmission unit 71 without having a wireless communication function of communicating with the communication network 11. As long as it has a function, it is easy to reduce the size and weight. Also, since the body motion information is generated on the side of the body motion status detection device 72, the power waveform generation unit 70 and the transmission unit 71 include an arithmetic circuit for generating rest information. There is no need to provide any other means, and the configuration of the power waveform generation unit 70 and the transmission unit 71 can be simplified, and the size and weight can be reduced. In particular, the arithmetic circuit becomes complicated, for example, when calculating the total body motion amount by integration. However, it is not necessary to provide such a complicated circuit in the power waveform generation unit 70 or the transmission unit 71. C. Third embodiment Next, a game device according to a third embodiment of the present invention will be described with reference to FIG. Note that, in the third embodiment, components common to those in the first and second embodiments are denoted by a symbol, and description thereof is omitted.冋 As shown in the figure, this game device has a power waveform generation unit 20 and a waveform shaping circuit 31, a parameter setting circuit 101, and a parameter storage unit 1, which are similar to the above-described 1β1 protruding embodiment. 0, a match processing unit 103, and an interface 104. The parameter setting route 101 sets the strength parameter used when this game device competes with another game device in the parameter storage section 102. The battle processing unit 103 compares the strength parameter set in the parameter storage unit 102 with the strength parameter of another game device input via the interface 104, Judge the win or loss. The content of the match and the result of the win or loss are displayed in the display concealment-105. Here, the game device according to the present embodiment is characterized by a parameter setting method, and includes a parameter storage unit 102, a battle processing unit 103, and an interface 1 which are other components. The display device 104 and the display device 105 have the same configuration as a normal battle-type game device, and a detailed description thereof will be omitted. Hereinafter, the parameter setting by the parameter setting circuit 101 will be described. . In this game device, the user swings the game device itself, and the parameter of the game is set in the parameter storage section 1.2 in accordance with the manner of swinging the game device. At this time, the parameter setting circuit 101 sets the strength parameter based on the power waveform input from the power waveform generation unit 20 via the waveform shaping circuit 31. As described above, according to the power waveform generation unit 20, a power waveform is generated according to the body motion as shown in FIG. 4, that is, according to the body motion of the game device caused by being swung by the user. . The illuminator setting circuit 101 detects a body movement state of the game device from the power waveform, and sets a strength parameter based on the detected body movement state. Here, by using the power waveform of the power waveform generator 20, a plurality of power waveforms can be obtained in the same manner as in the first embodiment. A plurality of types of body motion information can be generated, such as detecting a body motion level at a stage or detecting a total body motion amount per predetermined time. Therefore, if one parameter is set according to the result of one body motion information, a plurality of parameters can be set. In addition, since body motion information indicating the degree of body movement can be detected, it is possible to set a parameter according to the degree of body movement. For example, if two levels of royalties, such as weak and strong motion, can be detected, a parameter that increases only when weak motion is detected can be set. In this case, simply swinging strongly to Φ- is detected as strong body motion, and this parameter cannot be increased. Therefore, if you swing strongly, you can set the parameters according to the swing instead of the pure parameter settings such as the increase of the strength parameter, and the game characteristics can be improved.

For example, this is effective when the body motion detection device 10 is attached to the four places of the elderly person's left wrist, right wrist, left foot and right foot, and the operation of each part is continuously monitored. If the movement of the left hand and left foot of the old man is slower or does not move at all compared to the movement of the right hand and right foot from a certain period of time, guess a very dangerous situation that the body became paralyzed due to injury or moderateness Can be. Also, for example, the present invention is effective when the body movement detecting device 10 is attached to the actor's face, arms, wrists, legs, knees, hips, etc., and the operation of each part is continuously monitored. Particularly in dance and sword fighting, the movement of each part such as arms, legs, and waist is required to be smart (awkward) when looking at the entire body. In this case, each part By detecting body movements, the cause of awkward actions can be analyzed.

(2) In the first to third embodiments described above, the power waveform forming section 20 having the disc-shaped rotor 28 generates the power waveform that is the basis for generating the body motion ti5 report. However, the present invention is not limited to this. For example, a power waveform may be generated using a configuration as shown in FIG. As shown in the figure, the power waveform generator has a rotating shaft 222 made of a non-magnetic material, and the rotation of a rotating weight (not shown) that rotates by capturing body movement is not shown. The rotation is transmitted to the rotation shaft 222 through the culturing mechanism. In addition, a material other than a nonmagnetic material can be used as the rotating shaft 222. An annular permanent magnet 220 is provided around the circumference H of the rotating shaft 222. Around the rotation shaft 222, two yokes 2 21a composed of a magnetic material having a plurality of (four in the drawing) magnetic poles extending radially from the rotation center of the rotation shaft 222 are shown. , 22 1 b are provided so as to sandwich the permanent magnet 22 2 ◦, and the yokes 22 21 a, 22 1 b rotate with the rotation of the rotating shaft 222. The coils 2 25 are fixedly arranged at the four points on the rotating circumference of the radially extending tips of the yokes 2 2 1 a and 2 2 1 b, and the two yokes 2 2 la and 2 2 lb rotate In this case, the yokes 2 21 a and 22 1 b can pass above and below the coil 2 25, respectively. As the coil 2 25, a coil having a non-magnetic material or a hollow coil is used. Here, as shown in FIGS. 13 (a) and 13 (b), the center of the coil 2 25 is arranged on the rotation circumference of the tip of the yoke 2 21a, 22 1b described above. It has become. Also, the magnetic poles of the yokes 2 2 1 a and 2 2 1 b are arranged so as to face each other, and the number of magnetic pole pairs of the rotating weight 25 and the yokes 2 2 1 a and 22 1 b is the same. Have been. Under this configuration, when the rotating shaft 2 2 2 is rotated with the rotation of a rotating weight (not shown) capturing the body movement of the human body, the yoke 2 2 1 a, 2 2 lb is rotated accordingly.

Therefore, the detection accuracy for a weak body movement is improved. In addition, since the permanent magnet 222 is located close to the center of rotation, the amount of I can be reduced, and the β load applied to the rotating shaft 222 when an external impact is applied is small. However, the contact portion between the rotating shaft 222 and the shaft receiver is difficult to break. In the case shown in the figure, four coils 222 are provided. The number of coils provided may be one, and the number of coils provided is arbitrary.
