Description

  The present invention relates to a biological information detection apparatus, a patient monitoring system, and a method that can objectively recognize whether or not a subject is in a desired posture or movement.

  In recent years, computerization has progressed rapidly in general workplaces, and the number of people sitting in a chair for a long time has increased. For this reason, the rate of feeling physical fatigue and subjective symptoms is increasing. In addition, mental stress is increasing in many workplaces.

  A major cause of increasing these fatigue and stress is also to maintain an unreasonable posture for a long time. For this reason, it is important to work in a correct posture, and it is also possible to prevent stretching at regular intervals.

  In addition, taking a correct posture is important in all situations, and whether or not it is the correct posture is not easily recognizable by itself. I was judging.

  Even in such a case, it is not easy to recognize whether or not one's posture and movement are correct, and there are many cases where it is actually wrong even though it is considered correct.

  Also, in various performing arts and various exercises that require correct work, correct movement is required for a series of posture changes and movements. In the past, the instructor showed a sample of the correct posture and movement, and imitated the correct posture and movement by imitating the posture and movement of the instructor. Or, the instructor explained in detail and often performed an action that the instructor thought was correct.

  For this reason, if it is possible to easily grasp one's posture and movement without involving a third party, the correct posture and movement can be easily and reliably acquired. In particular, if the purification and movement can be grasped in real time, the correct posture and movement can be acquired more reliably and quickly. For this purpose, it is necessary to measure the posture and movement of the human body.

  For this reason, if a video camera is installed in the vicinity, and his / her posture and motion are photographed and displayed later, his / her motion and the like can be objectively confirmed without bothering other people's hands.

  In addition, as in Patent Documents 1 and 2, various sensors are directly attached to the subject to detect posture, movement, and the like. In Patent Document 1, as shown in FIG. 5, a large number of acceleration sensors are attached to each part of the body, and the detection data of each sensor is analyzed to determine how each part of the body actually moves. It was analyzed in detail.

  Further, in Patent Document 2, the position and orientation are estimated from information measured by sensors such as an acceleration sensor, an angular acceleration sensor, a gyro sensor, and sensing of an externally fixed marker, and the position is grasped by a GPS signal. Sweating volume, skin potential, eye movement, myoelectricity, electroencephalogram, brain magnetic field, vital signs, facial expression, complexion, voiceprint, tremor, body movement, blood sugar, body fat, blood flow, saliva component, breath component, excretion The condition of the subject was measured by detecting information on the component of the object and the component of the sweat.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an invention according to the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to the relative arrangement | positioning of a component demonstrated below, a numerical value, etc. at all, and it is not the meaning which limits the scope of the present invention to the following description unless there is a specific description.

  An embodiment according to the present invention provides a biological monitoring system that can monitor whether a desired posture is taken or whether a desired operation is performed correctly without giving an excessive load to the wearer. It is to provide.

  Hereinafter, the detailed configuration of the living body monitoring system according to the present embodiment will be described with reference to FIG. FIG. 1 is a diagram for explaining the overall configuration of a living body monitoring system according to a first embodiment of the present invention.

  Although only one biological information detection unit (synthetic resin case) 100 is shown in FIG. 1, the biological information processing apparatus 300 receives detection information from a plurality of biological information detection units and processes each of them. Is possible.

  Moreover, although the following description demonstrates the example provided with both the biological information detection unit 100 and the biological monitoring apparatus 300, it is not limited to the following examples, You may comprise only a biological information detection unit. In this case, transmission of detection information by the communication control unit 160 described later is not necessary.

  If the reference data registered in the reference data registration unit 120 is not configured to receive the reference data by wireless communication from another device, the communication control unit 160 may not be provided. In this case, it suffices if the reference data registration unit 120 described later is configured to be detachable and reference data according to the specifications is prepared.

  In FIG. 1, reference numeral 100 denotes a biological information detection unit according to the present embodiment, which is molded with a synthetic resin (plastic), for example, in order to reduce the size and weight. As the synthetic resin, a polystyrene type synthetic resin or a polymethyl methacrylate type synthetic resin can be used.

  The size is, for example, a light and small size of about 40 × 40 × 10 mm or less at the maximum. Thus, since it is small and lightweight, even if it is directly attached to the subject, the state of the subject can be detected with almost no load on the subject.

  In the biological information detection unit 100, reference numeral 110 denotes a control unit that controls the entire biological information detection unit, and includes, for example, a microprocessor, a memory, an input / output interface unit, and the like. A unique identification number, for example, a 14-digit identification number, is assigned to each of the other biological information detection units. This identification number is managed by the control unit 110.

  The control unit 110 compares and examines the detection results from the three-dimensional acceleration sensor 150 and other sensors, the details of which will be described later, and the reference data registered in the reference data registration unit 120 to determine the posture and movement of the subject. It has posture / movement determination means 110a which is a function for determining whether or not the body state of the subject is a desirable state. The posture / motion determination unit 110a can be realized by software, and can realize the function without affecting the shape of the unit.

  Reference data registration unit 120 is a reference data registration unit for registering reference data corresponding to the posture or motion that the subject wearing this unit 100 wants to monitor. The memory is configured to collect and register the detection data in advance.

  When the specification of the unit 100 is a dedicated unit that monitors a specific posture or motion, the reference data registration unit 120 can be configured by a read-only ROM.

  On the other hand, when the unit 100 is configured as a general-purpose product, it is desirable to configure the reference data registration unit 120 with a readable / writable memory, using standard reference data registered in advance, In accordance with the examiner, for example, it is desirable that reference data can be received from another device, for example, a biological monitoring device via the communication control unit 160 and stored in the reference data registration unit 120.

  Alternatively, reference data corresponding to the posture and movement to be monitored may be stored in a removable memory chip, and the memory chip storing the reference data may be attached to the unit 100 in accordance with a desired specification.

  Reference numeral 130 denotes a display unit capable of displaying the state of the apparatus, which is composed of, for example, a light emitting diode that emits light in a plurality of colors, changes the light emission color depending on the state of the apparatus, and displays continuously on or “blue” during normal operation. If there is a problem with the detection result, such as a defect or a posture or movement that is out of the detection result setting range, it will flash on or display in `` red '' and turn off after a certain period of time or when it is not operating. Conceivable.

  Reference numeral 140 denotes a temperature sensor that detects the body surface temperature (body temperature) of the subject, and uses, for example, a thermistor element whose resistance value varies with temperature. Since the method for detecting the body temperature is well known in electronic thermometers and the like, detailed description thereof is omitted. The temperature sensor 140 is not necessarily provided, and can be omitted.

  Reference numeral 150 denotes a three-dimensional acceleration sensor that detects the three-dimensional movement of the wearer (subject) and outputs a detected voltage value corresponding to the movement in each of the X, Y, and Z directions. To do. As the three-dimensional acceleration sensor 150, for example, KXM52 series manufactured by Kionix can be applied. If it is an acceleration sensor of the KXM52 series, it is a small DFN package of approximately 5 mm × 5 mm × 1.8 mm, and the biological information detection unit can also be made small.

  In the biological information detection unit 100 according to the present embodiment, the confirmation interval of the detection result from each sensor of the control unit 110 may be arbitrary, and the detection is performed at intervals of several mS, tens of mS, or hundreds of mS. Also good. This is because it detects human movements and does not change significantly in a short period of time.

Reference numeral 160 denotes a communication control unit, which communicates various detection values (for example, detection values of biological electrodes, detection values of three-dimensional acceleration sensors, detection values of temperature sensors) under the control of the control unit 110 in the communication mode. Data is transmitted to the control unit 360 at regular intervals.
Data transmission is performed at a frequency of 2.4 GHz, for example. It is also possible to adopt a configuration that does not include a communication mode and operates only with its own unit, and in this case, the communication control unit 160 can be omitted.

  It is desirable that the transmission data has a specification that reaches at least a distance of 10 meters or more, and more preferably a specification that reaches within the floor where the subject is present. As a result, the detection data can be reliably sent regardless of the position on the floor where the biological monitoring apparatus 300 is installed.

  Reference numeral 170 denotes an acoustic output unit, which is assumed to have a posture and motion assumed in advance when the detected data is significantly different from the reference data registered in the reference data registration unit 120 and exceeds the allowable range. For example, an alarm sound is output as the difference. By changing the sound output pattern according to the detected state, it is possible to notify the posture and motion state of the subject in more detail.

  Reference numeral 180 denotes a power supply unit, which employs a button battery in this embodiment. However, it is not limited to a battery, and it may be a primary battery or a secondary battery as long as necessary power supply is possible. Reference numeral 185 denotes a power switch, which instructs the present embodiment whether or not to supply operating power.

  Reference numeral 220 denotes a bioelectrode that is a skin surface electrode that can be attached to the surface of the living body. Since the bioelectrode 220 deteriorates in characteristics when used repeatedly, it is desirable to use a disposable electrode pad. For biological electrodes, it is possible to divert known general electrocardiographic electrodes as they are, and by using electrocardiographic electrodes for detecting electrocardiographic signals that are widely marketed as general-purpose products, dedicated electrodes, etc. Can be obtained at low cost and with necessary characteristics. For example, a “dispo electrode” made by Nihon Kohden or Fukuda Electronics can be used.

  Reference numeral 300 denotes a biological monitoring apparatus that receives various detection data from the biological information detection unit and monitors the state of the subject. The living body information detection unit 100 of this embodiment can examine the posture and movement of the subject alone, and the living body monitoring apparatus 300 is not necessary in the single operation mode.

  However, if various detection data from the biological information detection unit 100 can be received and analyzed, more detailed analysis of the condition of the subject can be performed, and finer management can be performed. It is also possible to store the detection history of the subject.

  Therefore, it is possible to grasp the working state and grasp progress of various movements. Further, by realizing the operation in the transmission mode in the biological information detection unit 100, for example, it is possible to output an alarm at a louder volume than when various kinds of notification sounds are output from the biological monitoring device 300, and the biological information detection unit 100 It is possible to prevent the consumption of 100 power consumption.

  In the living body monitoring apparatus 300, reference numeral 310 denotes a control unit that performs overall control, and 320 denotes a subject information management unit that receives detection data and operation status from the subject and manages detection information received for each subject.

  Reference numeral 330 denotes a reference data registration unit that registers subject information set in advance for each subject wearing the biological information detection unit, a monitoring posture of the subject, reference data for each type of operation, and the like. The data registered in the reference data registration unit 330 includes, in addition to detection data serving as a reference when performing a correct posture and operation registered in the biological information detection unit 100, a detection data pattern at the time of an incorrect posture and operation in advance. By registering a plurality of patterns and examining which data pattern the detection data from the biological information detection unit 100 is approximate to, it is possible to recognize how erroneous it is, and the display unit 340 By displaying information on how the error occurred, a more excellent effect can be obtained with a simple configuration.

  Posture monitoring includes posture monitoring such as whether or not the posture during work etc. is maintained in a desirable posture, and motion monitoring includes comparison with data when correct movement during dance practice, sports The present invention can be applied to a series of operations when performing sports, or a comparison of detection data during operations when performing exemplary operations and operations during sports training.

  Furthermore, in addition to the reference data when preferred actions and postures are known, incorrect posture and movement data often taken by unskilled people are collected, and detection data for several postures and movement patterns. May be registered and compared with the detection data from the subject to identify how the device is operating (how it is wrong). By configuring in this way, it is possible to increase the effects of training and the like as if there is a dedicated coach.

  Reference numeral 340 denotes a display unit that displays the operation state and posture state of the subject based on the received data from the biological information detection unit 100. In addition, emergency messages are displayed. An input unit 350 includes a keyboard or a card reader for inputting various instructions and information.

  Reference numeral 360 denotes a communication control unit that performs data communication with the biological information detection unit 100, and receives detected biological information and information indicating the state of the subject sent from the biological information detection unit 100 at regular intervals.

  Reference numeral 370 denotes an alarm output unit that can output various buzzer sounds and various synthesized sounds in addition to various acoustic outputs. For example, by changing the output pattern for each biological information detection unit that receives detection data via the communication control unit 360, it is possible to identify which biological information detection unit is an alarm, and further, for example, voice information As a result, the detection status can be notified to the subject in more detail. At this time, for example, by inputting subject information from, for example, the input unit 350 for each biological information detection unit, it is possible to specifically identify the subject and output an appropriate instruction.

  If the alarm is not output at a certain volume when dancing as described below or during exercise training, the subject may miss the alarm, but the detection data is transmitted to the biological monitoring device 300 (or the alarm output is set). By outputting a necessary warning (by requesting the biological monitoring device 300), it is possible to reliably convey the subject without worrying about power consumption. By displaying on the display unit 340 specific detection data, reference data, and matters that are the basis for outputting the alarm at this time, the subject can hear the output of the alarm and know the cause more reliably. , Learning effect can be improved.

  Details of the data communication control between the communication control units 160 and 360 will be described below. In the present embodiment, as described above, packet data is transmitted from the biological information detection unit at a substantially constant interval, and is received by the biological monitoring device 300.

  The packet includes an identification number (transmission source information) storage area that is assigned in advance for each biological information detection unit, a transmission number information (position information) storage area that is incremented each time a packet is transmitted, and a biological information detection unit. The data storage area to which the data to be transmitted and the like measured in (1) are allocated, the CRC storage area for storing CRC data that is an error correction code, etc., and the data storage area includes bioelectrode detection data, acceleration sensor direction data, Temperature sensor detection data and the like are stored.

  The biological monitoring apparatus 300 monitors the received data change for each received biological information detection unit in real time and selectively displays it on the display unit 340.

  In this embodiment, since it is assumed that the biological information detection unit 100 is directly attached to the subject, it is particularly required to reduce the size and weight. For this reason, when operating in a mode in which detection data from the biological information detection unit 100 is transmitted to the biological information monitoring apparatus 300, detection data from the temperature sensor 140, the three-dimensional acceleration sensor 150, and the biological electrode 220 are stored in a memory or the like. Without temporarily storing the reference data, the temperature detection data at the temperature sensor 140 and the detection potential at the biological electrode 220 and the detections at the X, Y, and Z sensors of the three-dimensional acceleration sensor 150 are respectively read at predetermined intervals. And may be stored and transmitted in a preset area of the transmission packet as necessary. As a result, the configuration of the biological information detection unit can be simplified, the load can be minimized, and a further reduction in size and weight can be achieved.

  Next, biological monitoring control by the biological monitoring system of the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart for explaining the basic biological monitoring control of the present embodiment. FIG. 2 illustrates an example in which one type of reference data is registered in the reference data registration unit 120. However, when a plurality of types of reference data are registered, they are registered at the beginning of the operation. The desired reference data is selected from the reference data.

  First, in step S1, for example, reference data (or reference data and some deformation data) prepared in advance for the posture or motion to be acquired in advance are registered or stored in the reference data registration unit 120. The biological information detection unit 100 is attached to the subject.

  It is desirable that the subject be worn with the bioelectrode 220 such that the accelerometer is substantially vertical in the middle of the chest in the middle of the front of the body. However, the present invention is not limited to the above example, and it is possible to detect the posture and the motion even if the bioelectrode 220 is not provided and is attached to a belt or the like.

  In the subsequent step S3, the power switch 185 of the biological information detection unit 100 is turned on to start the detection operation, and monitoring of the subject is started. In response to this, the subject also performs the targeted posture and movement.

  The control unit 110 of the present embodiment reads detection data from each sensor at a predetermined interval in step S5. In a succeeding step S7, it is determined whether or not the transmission mode is set. If it is not the transmission mode, the process proceeds to step S10.

  On the other hand, if the communication control unit 160 is provided in step S7 and the transmission mode is to transmit detection data to the biological monitoring device 300, the process proceeds to step S9, and the detection result of the sensor is sent to the communication control unit 360 of the biological monitoring device 300. Send. Then, the process proceeds to step S10.

  In step S10, it is checked whether or not the detection data from the sensor has been read for a predetermined time. If the predetermined amount has not been detected, the process returns to step S5 to continue reading the detection data of the sensor.

  When the detection data for a predetermined time is read in step S10, the process proceeds to step S12, where the control unit 110 compares the detected data with the reference data registered in the reference data registration unit 120, and the detection data is the reference data. Is identified and the two data are compared (posture / motion determination means 110a).

  Waiting for a certain amount of data to be collected can be done by monitoring the posture and movement, or by looking at the sensor output at the moment, what kind of posture change has been made, and what kind of movement is performed. This is because it is necessary to detect body movement for a predetermined time in accordance with the monitoring target, and a series of posture changes and motion conditions within a predetermined range are compared with reference data.

  In the case of posture detection, it is sufficient to compare the reference data and detection data when the posture is correct. In the case of a series of operations, the time from the start of detection in step S3 or the matching between the detection data and registered data is performed. The detection data corresponding to the operation at the data acquisition timing is identified and compared.

  When the detection target is an operation and the detection time is short, for example, when it is sufficient to compare the detection data for several seconds, such as a golf swing described later, the greatly changed portion is set as the comparison target. To do. When the state monitoring takes a long time, the detection data is monitored in real time, and it is monitored by comparing whether it is out of the set range.

  Further, when the body temperature is detected by the temperature sensor 140 or the biological signal is detected by the biological electrode 220, it can be immediately known whether or not the unit has been removed from the subject, and a warning is output immediately. It is possible to effectively prevent the unit from being lost. Further, by detecting the body temperature by the temperature sensor 140, the health condition of the worker can be monitored, and early detection of poor physical condition can be expected.

  From the detection result of the biological electrode 220, the exercise state of the subject can be confirmed, for example, in the state of heartbeat, and it can be detected whether, for example, work is being performed or resting in conjunction with the detection result of the three-dimensional acceleration sensor 150. Yes, it is possible to easily and objectively grasp the actual work.

  In subsequent step S14, as a result of the comparison by the posture / motion determining means 110a of the control unit 110, it is determined whether or not the difference is within a preset range. If the difference is small and the difference is within the setting range, it is determined that the state is correct, and the process returns to step S5 to continue detection of posture and motion.

  Whether or not the position is within the set range by the posture / motion determining unit 110a is determined to be out of the set range when the time outside the set range continues for a certain time or more. This is because the setting range may be temporarily outside due to the influence of noise or the like, and it is necessary to remove the influence of noise.

  On the other hand, if the difference between the detection data and the reference data exceeds the preset range in step S14, the process proceeds to step S16 to check whether the alarm output mode is set. If not in the alarm output mode, the process proceeds to step S20.

  If the alarm output mode is set in step S16, the process proceeds to step S18, where an alarm is output for a predetermined time, and then the process proceeds to step S20. For example, an alarm is output when the posture is out of the desired range because the posture is lost, or when the posture is not taken, the golf swing must be It is possible to respond to a wide range of posture movements according to the reference data registered in the reference data registration unit 120, such as outputting an alarm sound when the center of gravity is moving with an action that must suppress the center of gravity movement It is.

  In step S20, the above determination result is displayed on the display unit 130, and the process returns to step S5 to continue monitoring. When a series of detections are to be terminated, detection by the sensor is continued until a stop button (not shown) is pressed or the power switch 185 is turned off.

  However, the end of detection is not limited to the above example, and when the biological information detection unit 100 detects that the subject is not attached to the subject, the detection operation is automatically stopped and the detection is completed. It may be controlled to restart the detection operation.

  Further, for example, when the biological electrode 220 is detecting a biological signal, or when the temperature sensor 140 is detecting the body temperature, the three-dimensional acceleration sensor 150 detects the non-stationary state of the subject. In this case, it is possible to operate as a monitoring mode, compare detection data from sensors, and stop processing when there is no detection from these sensors for a predetermined time.

  In the above description, the temperature sensor 140, the three-dimensional acceleration sensor 150, and the biological electrode 220 are all provided and the detection data from each sensor is comprehensively determined and determined. However, the present invention is limited to the above example. For example, the sensor may include only the three-dimensional acceleration sensor 150 or may further include only the temperature sensor 140. Even if the living body electrode 220 is not provided, it is possible to detect the respiratory state and the heartbeat by attaching the example embodiment unit to the chest, and to detect whether it is active or sleeping. At the same time, changes in posture can be detected.

As an example of posture monitoring, an example will be described in which the biological information detection unit is used for correct posture control, rest at predetermined intervals, and monitoring of the state of implementation of stretch in a computer operation job in the workplace.

  In general, when sitting on a chair and operating the keyboard while looking at the display screen, the desired posture is to make the pelvis slightly above, put the power on the abdomen, put the lumbar vertebrae, thoracic vertebrae on it, raise the head, It is said that the posture is to maintain a so-called natural S-curve that extends the cervical spine. However, it is difficult to continue conscious of such a posture, and the pelvis tends to tilt backwards when the user is concentrating on the work, and the natural S-shaped curve is likely to collapse.

  In addition to continuing to watch the display screen for a long time, it causes stiffness of the body and fatigue of the eyes, so it is required to take a break every hour. For example, according to the Ministry of Health, Labor and Welfare's “Guidelines for Occupational Health Management in VDT Work”

(1) Ensure that continuous work does not exceed one hour.
(2) Provide a work downtime of 10 to 15 minutes between continuous work. (3) Provide a short break of about 1 to 2 times within one continuous work time.
For example, the following files and data are registered in the reference data registration unit 120 of the biological information detection unit 100.

そして、基準データが登録されている生体情報検出ユニット１００を例えば胸部の身体正面中央近傍に装着（３次元加速度センサ１５０が略垂直になる様に）し監視を開始させる。

Then, the biological information detection unit 100 in which the reference data is registered is mounted near the front center of the body of the chest, for example (so that the three-dimensional acceleration sensor 150 is substantially vertical), and monitoring is started.

  After monitoring is started, whether or not the correct posture is maintained is constantly monitored, and if the working posture is out of the preset range, for example, a warning sound of the working posture is output from the sound output unit 170 When it returns to the correct posture, the alarm sound output is stopped. As the alarm sound, for example, a buzzer sound “Peep Peep” at a predetermined interval is output, or a voice guidance such as “Return to correct posture” is output.

  Further, although omitted in the description of the processing in FIG. 2, it is set so as to monitor the passage of time from the start of detection, and a notification sound for prompting to take a short pause when the time from the start of work to the short pause has elapsed, For example, a voice message such as “Continuous work time is XX minutes. Please pause.” Or a buzzer sound of a predetermined pattern is output.

  During the brief rest period, it was determined that the person continued to work by monitoring whether he / she got up from the chair and performed a light exercise, or performed a relaxing action such as moving the body while sitting in the chair. In such a case, a notification is made to further encourage a short break.

When the time for a short pause has elapsed, a short pause stop notification sound is output. For example, a message “Please stop working and return to work” or a buzzer sound to notify the start of work is output.
When the allowable continuous work time has elapsed from the start of work, work suspension notification data is output to notify the operation suspension. For example, it is a work pause time, so let's pause the work and move the body "or a buzzer sound indicating the work pause.

  Then, it is monitored whether the user stands up from the chair during the work pause and performs a light exercise, or performs a relaxing operation such as moving the body while sitting on the chair. When it is determined that the work is continued, a notification is made to further prompt the work to be interrupted.

  When a work pause time, for example, 10 to 15 minutes elapses, a work resumption notification sound (work start permission notification sound) is output. For example, a message “Pause time has ended. Please start work.” Or a buzzer sound to notify the start of work is output.

  By only attaching the unit of the first embodiment to a worker who performs computer operation or the like, not only can the disorder of posture during work be recognized in real time, but also it can prevent continuous work for a long period of time and can also perform a relaxing operation during rest Can be monitored. By transmitting these detection data to the living body monitoring apparatus 300 and accumulating and analyzing the detection data, it is possible to accurately know the state during the work, and it can be utilized for the health management of the worker. Further, even when the patient is in poor physical condition or has complained of fatigue, it is possible to objectively know whether the cause is the attitude during work.

Although the above description has been given by taking the case where it is attached to a computer operator as an example, it can be applied to any work site as it is. For example, if it is attached to a student at a school or a cram school, and it detects judiciary, it can easily detect whether you are concentrating on a class with a good posture, whether you are concentrating, sleeping, etc. It is possible to call attention to the students and concentrate on the lessons.
Furthermore, even at the production site of the product, the work status can be monitored in real time, and even in the event of an accident, the status can be quickly alerted and the damage can be minimized.

In addition, for example, in this case, by providing the biological information detection unit 100 with the vibration function of the mobile phone, the subject can be made aware of his / her state without causing trouble to others. This is the same for other examples, and it is possible to notify only the examinee without informing the third party of the notification output, and it can be used even in a quiet workplace or library. be able to.
[Example 2]

  Next, as an example applied to exercise training, a case where a swing is performed by wearing the unit of this example during golf practice will be described below. You may make it mount | wear when actually playing golf on a golf course. In the case of the second embodiment, for example, the following data is registered in the reference data registration unit 120.

このようにきめ細かな各種のスイング時の検出データに対応させることができ、あたかも専用のコーチについているかの如き練習効果を得ることができる。
すなわち、フルスウィング時とハーフスウィング時、アプローチスウィング時、バンカーショット、パタースウィングなどスウィングによって体重移動や回転軸ぶれ、前傾姿勢乱れに対する許容度が異なっているにもかかわらず、適切に対応することができる。
更に、例えば自身が選択したプロ選手のスイング時の検出データを基準データとすることで、より趣味性の高い装置とすることも可能である。

In this way, it is possible to correspond to various types of detection data at the time of various swings, and it is possible to obtain a practice effect as if it is a dedicated coach.
In other words, respond appropriately despite full swing, half swing, approach swing, bunker shot, putter swing, etc. Can do.
Further, for example, by using detection data at the time of a swing of a professional player selected by itself as reference data, it is possible to make the device more hobby.

  For example, when applying to a golf lesson conducted by a driving range or a golf school, it is possible to objectively recognize one's own movement by registering reference data regarding the swing movement to be mastered according to the curriculum. And experience how to get the right swing.

  In particular, there are many examples of believing that you are swinging yourself, but this example allows you to make the unit recognize the objective facts naturally without difficulty, and how it moves. Since it is possible to grasp in real time whether or not the swing is correct, it is possible to provoke a willingness to positively correct defects and the like. In addition, it is possible to easily confirm where the person is wrong by simply wearing it at home at any time for swinging at home, and it is possible to easily return to the correct swing.

  In the above description, the example in which the reference data is registered and the reference data is compared with the detection data has been described. However, the reference data is not limited to data that is generally considered optimal (theoretical ideal data, etc.). For example, in the case of a professional who has advanced technology, register the detection data at the time of your good performance or the swing that seems to be the best as your own reference data, and when it is in bad condition, for example, slump In such a case, the difference can be objectively grasped by comparing the own data registered in advance with the detected data. Thereby, the hint of escape of a slump can be given.

  The above is not limited to golf, but can be applied to exercise in general. For example, the present invention can be applied to a baseball batter's batter box or a pitcher's pitch form. Also, in every sport, register your own detection data at good times, and easily compare it with your own detection data when you are in a bad condition. It can be objectively grasped, and slumps can be minimized.

Example 3
The following explanation is based on reference data when dancing as reference data (for example, sensor detection data when dancing well is registered as reference data in the reference data registration unit 120, for example, a person who learns or wants to learn dance However, by wearing the unit of Example 3 and performing a dance, it is possible to objectively know which part of the user must be corrected.

Also in the case of the third embodiment, as in the case of the second embodiment, by registering reference data that matches each movement and detection data that matches a typical error pattern for each type of dance, Detailed corrections are possible as if they were learning from the coach. It is desirable to register the following standard data for each type of dance, such as Japanese dance, modern dance, Latin dance, folk dance, street dance, tap dance, hula dance.
A registration example of the reference data registration unit 120 for each type of dance of Example 3 is shown below.

  For example, Japanese dance requires a slightly lower back, restrains the vertical movement of the hips, and handles the foot gently and supple. Even in such a case, it is possible to recognize in real time, for example, what kind of movement has to be corrected.

  Also, in the case of ballroom dancing, etc., the body movement shape varies depending on the type of dance, but there are unique postures and steps to be taken by each dance, and it is detected when an exemplary movement is made By registering power data as reference data, basic movements in various dances can be easily learned. In particular, you can objectively confirm how to take steps and dance with a good sense of rhythm.

  Furthermore, for any target such as jazz dance or hip-hop dance, it is possible to easily confirm the difference from the reference movement and its own tempo. On the other hand, even when applied to dance based on traditional music, you can easily and objectively recognize differences from standard movements and rhythms, and live in an educational environment where there are few opportunities to teach directly to coaches and teachers. Efficient practice is possible even with things. Furthermore, even if the number of enthusiasts is small and the teacher to be taught is not nearby, or even when the teacher has to leave temporarily or for a long time, the practice effect can be improved if only the reference data is registered.

  In this way, information corresponding to the detection results when performing typical dances when practicing various dances such as Japanese dance, modern dance, Latin dance, folk dance, street dance, tap dance, hula dance, etc. By using it as reference information, information corresponding to the detection results when the posture / movement is often mistaken is prepared as comparison information, and what posture / movement is correct when practicing dancing Can be known by hand, and the cause can be grasped objectively even when the posture / movement is incorrect.

Example 4
In the following explanation, sensor detection data in a correct form when walking is registered as reference data in the reference data registration unit 120, and for example, a person who walks or who wants to wear a correct walking form is an example By wearing the unit 3 and walking, you can objectively know which part of you must correct.

In the case of the fourth embodiment, for example, the following data is registered in the reference data registration unit 120.

  For example, in exercise walking, it is important to increase the kicking force (propulsive force). For example, it is required to bend the elbow to 90 degrees so that it can swing particularly well backward. This movement can also be detected by movement in the left-right direction by the three-dimensional acceleration sensor 150.

  Also, the foot bumps are like putting your hips on your hind legs, landing from your heel, stepping on the other leg one step forward, then putting your hip on the front leg, and naturally moving the center of gravity forward If you push it out and use the force that the center of gravity moves forward to finally kick the ground with the thumb of your back foot, you can walk efficiently without getting tired. This movement can be detected by the three-dimensional acceleration sensor 150.

  In addition, for example, in order to take one breath in eight steps and take a long breathing time according to the stride, for example, one step is repeated “suck, inhale, inhale, inhale, exhale, exhale, exhale, exhale”. It is possible that. This movement can also be detected by the three-dimensional acceleration sensor 150, for example, movement in the front-rear and left-right directions.

The breathing method is not limited to the above example, and one breath may be taken in four steps, and detection of breathing may be omitted.
As described above, according to the present embodiment, it is possible to monitor whether or not the posture of the subject is correct, and it is also possible to control the actual work, so that it is possible to easily recognize whether the work is in an appropriate environment. For this reason, it is possible to effectively prevent an unreasonable load from being given unknowingly.

  In addition, when practicing various exercises, information corresponding to detection results when performing typical postures and movements is used as reference information, or information corresponding to detection results when postures and movements are often mistaken is compared. Prepared as information, it is possible to know how to move correctly, and to know the cause objectively even when it is incorrect.

  As described above, according to the present embodiment, each person can objectively recognize his / her state, and can correctly and accurately recognize the correct posture and action. From this characteristic, for example, by distributing the unit of this embodiment as a part of the teaching material as reference data for distance learning that improves the movement of the body, it is possible to confirm its own movement by itself. For this reason, the learning effect can be improved dramatically.

  Furthermore, it is possible not only to attach a biological information detection unit equipped with a biological electrode and an acceleration sensor and a temperature sensor that can detect the posture and movement state of the subject, but also to measure in real time by wireless communication. Data can be sent to the monitoring device.
