Description

[Technical field]

[0001] The present invention relates to a training system, a training method, and a training application that improve the reproducibility of a wearer's body movements in shooting training such as clay shooting and other sports training. [Background technology]

[0002] Generally, there are various sports that require reproducibility, one of which is shooting sports such as clay target shooting. Clay target shooting is a sport in which a shotgun is used to shoot and destroy targets (clays) shot into the air, and requires accurate shooting technique and fast reflexes. The shooter must react to the moment the clay is shot, aim the gun, chase the clay and shoot it down accurately. Since conditions such as wind direction, wind speed, target shooting angle, and altitude are constantly changing, the shooter must react quickly according to the situation and use the appropriate shooting technique.

[0003] Conventionally, there is a device for simulating shooting using a laser gun that emits laser light as a device for target practice. For example, Patent Document 1 discloses a target device that prepares a laser gun that emits laser light, provides a target board that detects the laser light, and reports the hit state when the laser beam hits the target board. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 09-042893 Summary of the Invention [Problem to be solved by the invention]

[0005] However, compared to real-life training using real guns, shooting training using laser guns is difficult to completely reproduce the real shooting scene because the environment and conditions are different. Also, since laser guns do not use real bullets, there is no recoil and it is not possible to completely reproduce the feeling of real shooting, so there are limitations to acquiring accurate shooting techniques.

[0006] Therefore, in target practice, it is ideal to carry out so-called live-fire training, in which a gun is loaded with live ammunition and the live ammunition is fired by aiming at a stationary target or a flying target, etc. This type of live-fire training has the advantage that it allows a person to acquire more accurate and advanced shooting techniques that are in line with reality by repeatedly firing live shots.

[0007] In actual clay shooting competitions, shooting is done under extreme tension and stress, so it is necessary to master the techniques to reproduce the movements as in training even under such conditions. However, with normal live shooting training, it is not possible to acquire the techniques to reproduce the speed and rhythm of movements even under extreme tension and stress, so there is a problem in that it is not possible to train in a way that is suited to real combat.

[0008] Therefore, the object of the present invention is to provide a physical training system that enables athletes to acquire the skills to reproduce the speed and rhythm of movements as trained even under extreme tension or stress in shooting competitions and other sports, thereby enabling training that is suited to actual combat. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention provides a system for training a wearer's body movements, comprising: A detection means attached to a part of the wearer's body or to an instrument carried by the wearer, for detecting an acceleration or angular velocity acting on the part of the body or the instrument, or a change therein; an acoustic signal generating unit that generates an acoustic signal that changes in response to the acceleration or angular velocity detected by the detection means, or a change therein; an output means for outputting a sound based on the sound signal generated by the sound signal generating unit; Equipped with.

[0010] The present invention also provides a method for training a wearer's body movements, comprising: (1) a detection step in which a detection means attached to a part of a wearer's body or an instrument carried by the wearer detects an acceleration or angular velocity acting on the part of the body or the instrument, or a change therein; (2) an acoustic signal generating step in which an acoustic signal generating unit generates an acoustic signal that changes in response to the acceleration or angular velocity detected by the detection means, or a change therein; (3) an output step in which an output means outputs a sound based on the sound signal generated by the sound signal generating unit; Includes.

[0011] The above-mentioned system and method according to the present invention can be realized by executing the program of the present invention written in a specific language on a computer. That is, the program of the present invention can be installed in an IC chip or memory device of a general-purpose computer such as a portable terminal device, a smartphone, a wearable terminal, a mobile PC or other information processing terminal, a personal computer or a server computer, and executed on a CPU to construct a system having the above-mentioned functions and implement the method according to the present invention.

[0012] The program of the present invention can be distributed, for example, through a communication line, and can be transferred as a package application that runs on a stand-alone computer by recording it on a computer-readable recording medium. Specifically, the recording medium can be a magnetic recording medium such as a flexible disk or cassette tape, an optical disk such as a CD-ROM or DVD-ROM, or a RAM card. The computer-readable recording medium on which the program is recorded makes it possible to easily implement the above-mentioned system and method using a general-purpose computer or a dedicated computer, and also makes it easy to store, transport, and install the program.

[0013] In the above invention, it is preferable that the audio signal generating unit generates the audio signal so that the volume, pitch, or tone changes in response to a change in acceleration or angular velocity detected by the detection means. Also, in the above invention, it is preferable that the audio signal generated by the audio signal generating unit is sent to the output means via wireless communication means, and that the wireless communication means transmits the audio signal using an analog signal.

[0014] Furthermore, in the above invention, it is preferable that light from a light-emitting body attached to a part of the wearer's body or an instrument carried by the wearer is projected onto a screen, and a light trace analysis means records the light trace projected onto the screen, and detects the acceleration or angular velocity, or changes therein, acting on the part of the wearer's body or the instrument carried by the wearer based on the recorded light trace. Alternatively, in the above invention, it is preferable that a sensor means attached to the part of the wearer's body or the instrument carried by the wearer detects the acceleration or angular velocity, or changes therein, acting on the device itself. Effect of the Invention

[0015] According to the present invention, in shooting and other sports competitions, it is possible to acquire techniques that enable the reproduction of the speed and rhythm of movements as trained even under extreme tension or stress, thereby realizing training that is suited to actual combat.

[0016] More specifically, in the present invention, an acceleration sensor attached to a part of the wearer's body or to a portable device detects the rhythm and speed of the wearer's body movements and actions, and converts them into audio signals. Based on these audio signals, sound is output from the output means, allowing the wearer to hear sounds that match the wearer's own movements, rhythm and speed.

[0017] As a result, through training using this invention, the speed and rhythm of body movements can be memorized and mastered as sound patterns, so that in actual combat, the body movements to be reproduced can be imagined by recalling the sound. By imagining the sound of the mastered pattern and performing movements in accordance with it, the speed and rhythm of movements can be reproduced even under extreme tension or stress.

[0018] This physical training system can be applied not only to shooting competitions but also to other sports and athletic competitions. For example, in gymnastics, the athlete's movements can be adjusted accurately by outputting sounds that match the rhythm of jumps and rotations, and in dance competitions, the athlete can adjust his or her movements while being conscious of the rhythm of the music. This system can provide a very useful training tool for athletes who want to acquire accurate techniques and rhythms in sports and athletic competitions. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, with reference to the accompanying drawings, an embodiment of the physical movement training system according to the present invention will be described in detail. FIG. 1 shows the configuration of a live shooting training range for various clay shooting sports in which the physical movement training system is introduced in each embodiment. Note that the embodiments shown below are merely examples of devices for embodying the technical idea of ​​this invention, and the technical idea of ​​this invention does not specify the material, shape, structure, arrangement, etc. of each component part as described below. The technical idea of ​​this invention may be modified in various ways within the scope of the claims.

[0021] (On the value of live ammunition shooting as a sport) First, regarding the system according to this embodiment and the value of live ammunition shooting as a sport, one of the technical objectives of this embodiment is to provide a solution to the difficult issue of time lag in live ammunition shooting. This time lag is an element that enhances the competitive nature of shooting sports, and specifically, there are three types of time lag:

[0022] The time lag between the moment you consciously decide to pull the trigger and your finger actually starting to move (2) The time lag between pulling the trigger and the hammer touching the detonator, igniting and causing the gunpowder to explode.

[0023] (3) The time lag between when a pellet is released by an explosion and when it reaches the target.

[0024] If these time lags did not exist in live-fire shooting, anyone could easily hit the target. However, it is impossible to completely eliminate these time lags through training.

[0025] Therefore, it is necessary for the shooter to understand these time lags, which the shooter cannot sense intuitively, and to train his or her mind and body accordingly. The reason this is necessary is because shooting can be recognized as a sport, not just a game, and it is believed that acquiring the skills to manage and adapt to these time lags will lead to improved shooting technique and better performance.

[0026] The system of the present invention provides a unique approach to the challenging issue of time lag, which affects the projectile and the "shot conditions" relative to each other, and which changes due to the movement of the impact point and the dynamics affected by the successive gun movements made to shoot the projectile.

[0027] Therefore, understanding and improving this dynamics is the core of practice, but currently, many clay target shooters rely on intuition and experience to understand the dynamics, which requires a considerable number of actual shots, and this is also an obstacle to the development of clay target shooting.

[0028] The system of this embodiment converts the movement into visual and audio data, allowing the trainee to easily recognize the movement, and thus enabling training indoors without actually firing a bullet. This change in environment will enable clay shooting practice to shift significantly from the current practice of mass shooting at a shooting range to indoor practice, and can be said to be a new revolutionary step in shooting practice.

[0029] (Configuration of the live firing training range) Next, the configuration of the live shooting training range on which the system according to this embodiment is based will be described. In each embodiment described below, clay shooting is a sport in which a shotgun is used to shoot and destroy targets (clays) shot into the air, and the shooter reacts to the moment the clay is shot, aims his gun, chases the clay, and shoots it down accurately. Clay shooting includes trap shooting and skeet shooting, in which the clays are shot at various angles and speeds in trap shooting, and in which the clays are released at a relatively fixed position and angle in skeet shooting. As for the type of shooting range, skeet shooting is performed in a shooting range that draws a circle with a radius of 25 yards, and the clays are shot from areas on the ground that are divided like clock faces.

[0030] As shown in FIG. 1(a), the skeet shooting range is a shooting range for skeet shooting, which is a type of clay shooting, and multiple shooting stands 53 are installed around a semicircular competition area 5. A pooler house 54 is located in the center of the arc part of the semicircular competition area. In skeet shooting, the clays flying from the left side are called pools, and the clays flying from the right side are called marks. High houses 51 and low houses 52, in which launchers for launching the clays are installed, are located on both sides of the competition area 5. The clays T1 are launched from the high houses 51 and low houses 52 toward a center pole 55 in the center. A player P1 moves from each shooting stand 53 in order to shoot the clays T1 that are launched and fly in a certain direction. At this time, the clays T1 are always launched from the same place, but the flight angle of the clays T1 appears to change as the player P1 changes his / her standing position.

[0031] On the other hand, as shown in Fig. 1(b), the trap shooting range 6 is a shooting range for trap shooting, which is a type of clay shooting, and in trap shooting, an athlete P1 shoots down clays T1 shot from a shooting stand 62a, the clays T1 being shot from a shooting machine installed at different positions in a trap house 63. In the trap house 63, the shooting machine that shoots the clays T1 is installed at a position corresponding to a center line 64, the trap house 63 is placed in front of the athlete P1, and the clays T1 are shot from the trap house 63 at random angles and speeds according to the control from the puller house 61.

[0032] The athlete P1 moves from the first shooting station 62a in order, shooting down one clay T1 at each shooting station 62a. When shooting is finished at all stations, the next shooter repeats the same process. In trap shooting, the athlete releases the clay by vocalizing a command, so a microphone 62b is installed at each shooting station 62a. The microphone 62b detects the voice and sends a signal to the trap house 63, which controls the timing at which the clay is released. Using the microphone 62b, the athlete P1 can shoot at his own pace.

[0033] (Configuration of the physical activity training system) Specifically, in this embodiment, the present invention is applied to clay shooting using an information processing terminal 100, and a system is provided that enables physical training for clay shooting. Note that the embodiments shown below are merely examples of devices for embodying the technical idea of ​​this invention, and the technical idea of ​​this invention does not limit the material, shape, structure, arrangement, etc. of each component to those described below. The technical idea of ​​this invention may be modified in various ways within the scope of the claims.

[0034] Fig. 2 is a block diagram showing the internal configuration of a physical movement training system using an information processing terminal 100 according to this embodiment. As shown in Fig. 2, the physical movement training system according to this embodiment is generally composed of an information processing terminal 100 that is attached to an athlete P1 or installed around the athlete P1, and a wearable sensor 21 that is attached to the body of the athlete P1 or to a shotgun 2 used by the athlete P1 and wirelessly connected to the information processing terminal 100. In this embodiment, the system can be constructed within a range where short-distance wireless communication between the information processing terminal 100 and the wearable sensor 21 can be connected.

[0035] (Configuration of each device) Each device constituting the above-mentioned physical exercise training system will now be described.

[0036] (1) Wearable Sensor The wearable sensor 21 is a device attached to or built into the part of the athlete P1 where the exercise is performed or the shotgun 2, and is a sensor that detects three-dimensional displacement or acceleration of the part to be worn. In this embodiment, the wearable sensor 21 is built into the shotgun 2. The wearable sensor 21 is equipped with a three-axis accelerometer that measures the acceleration of an object, a three-axis gyroscope that detects the angular velocity of an object, and a three-axis magnetic sensor that measures the magnitude and direction of a magnetic field, and is capable of detecting nine-axis movement. Each wearable sensor 21 can be attached and detached to the wearer's shoes, belt, clothes, etc. by a member such as a clip, and each sensor can be easily attached and detached to perform measurements, making it easy to perform continuous measurements without imposing a burden on the wearer.

[0037] The wearable sensor 21 has a wireless communication unit, which has an internal antenna and is capable of performing communication processing with the information processing terminal 100 by a function of executing a data communication protocol for short-range wireless communication such as BTLE (Bluetooth (registered trademark) Low Energy, Bluetooth (registered trademark) 4.0). In this embodiment, the wireless communication unit of the wearable sensor 21 adopts BTLE as a protocol for low power consumption communication, but it is also possible to adopt, for example, ANT, ANT+, etc. Also, normal Bluetooth (registered trademark) can be adopted.

[0038] (2) Information terminal device 2, the information processing terminal 100 according to this embodiment is a small terminal device such as a smartphone, and various functions can be implemented by installing various application software, and in this embodiment, a radio wave test application is installed to make the smartphone function as a terminal device for physical movement training. This information processing terminal can be realized by a smartphone, for example, a general-purpose computer such as a personal computer, or a dedicated device with specialized functions, and includes a tablet PC, a mobile computer, and a mobile phone.

[0039] Specifically, the information processing terminal 100 includes an application execution unit 110, which is an arithmetic processing device, a memory 120, an output interface 102, and an input interface 101. The information processing terminal 100 also has a function of collecting detection results detected by the wearable sensor 21, and is capable of acquiring the detection results by the wearable sensor 21 by performing mutual communication processing with the wearable sensor 21 via the wireless interfaces 101a and 102a. The memory 120 of the information processing terminal 100 functions as a body movement recording unit that records the detection results by the wearable sensor 21 as body movement data. Here, the body movement data is raw data detected by various sensors, and this body movement data is recorded and analyzed, and is used for data processing such as extracting necessary information and correcting it.

[0040] The detection results transmitted from the worn sensors 21 are accompanied by sensor identification information for identifying the worn sensors 21, making it possible to determine which worn sensors 21 the detection results were obtained from. The identification information also includes time information when the detection results were obtained from each worn sensor 21.

[0041] The wireless interface 101a or 102a is a module that controls the transmission and reception of various information via a communication network and short-range wireless communication such as Wi-Fi or Bluetooth (registered trademark), and communicates with each wearable sensor 21 using various protocols and transmits and receives data with the above-mentioned server device, etc. via 3G communication.

[0042] Furthermore, the information processing terminal 100 includes an output interface 102 and an input interface 101. The input interface 101 is a device that connects to external devices such as the external camera 131 in addition to the wearing sensor 21, and can also connect to a remote control device such as a remote control. In addition, the output interface 102 can be connected to devices that output video and audio, such as a display and a speaker. In particular, the output interface 102 includes a display unit such as a liquid crystal display, and this display unit is configured to be superimposed on a touch panel, which is an input interface.

[0043] In particular, audio output devices such as speakers, headphones, and earphones can be connected to the output interface 102, and these audio output devices have the function of outputting the body movements of the athlete P1 as sound.

[0044] On the other hand, the input interface 101 can be connected to a video acquisition means such as an external camera 131. This external camera 131 also has a function of acquiring video data capturing a light trail of a laser pointer of a laser gun projected on a screen during indoor training, which will be described later. The video data acquired by this external camera 131 includes video data in which a video is recorded, audio data recorded together with the video, and metadata such as time stamps such as the time of shooting, the time of end, and the elapsed time.

[0045] The video acquisition means connected to the input interface 101 also includes a built-in camera built into the information processing terminal 100, and video data captured by these video acquisition means is acquired by the image analysis unit 117 and stored in the memory 120 as a video file 120a, or is provided for body movement analysis processing in the body movement analysis unit 112. Note that the video data acquired from the external camera 131 includes streaming data acquired sequentially in real time during shooting, as well as video data in a file format captured by the external camera 131 and stored externally, which is downloaded and acquired after shooting.

[0046] In this embodiment, the information processing terminal 100 has a function of analyzing the body movement of the wearer based on the detection result acquired from the sensor and generating body movement data. Each functional module of the information processing terminal 100 is virtually constructed on the CPU by executing the body movement training program of the present invention in the application execution unit 110. In detail, the application execution unit 110 virtually constructs a detection signal acquisition unit 111, an image analysis unit 117, a body movement analysis unit 112, an audio signal generation unit 113, an output signal control unit 114, a training management unit 116, and a data control unit 115 by executing the body movement training application.

[0047] The detection signal acquisition unit 111 is a module that acquires detection signals from the worn sensor 21 via the input interface 101, and in this embodiment, it communicates wirelessly with the worn sensor 21 and acquires the detection signals of various sensors, which are the detection results, in real time. In this embodiment, the detection signals are analog signals, and the body movements of the athlete P1 can be converted into sound and output in real time via the body movement analysis unit 112. The detection signals acquired by the detection signal acquisition unit 111 are temporarily stored in the memory 120, and then sent to the training management unit 116 as necessary.

[0048] The body movement analysis unit 112 is a module that calculates the displacement, rotation, and acceleration of the athlete P1 and the shotgun 2 that are the subject of analysis, based on the detection signals of the sensors acquired by the detection signal acquisition unit 111 or the image analysis unit 117, and video data, and generates the body movement of the athlete P1 as body movement data. Here, the detection results by the mounted sensor 21 are values ​​measured by a so-called 9-axis sensor, and in this embodiment, are the direction and magnitude of the acceleration (including gravitational acceleration) acting on the object, the angular velocity (magnitude, direction, center position) of the object, and the magnitude and direction (angle) of the magnetic field.

[0049] The body movements calculated here include, for example, in a clay shooting competition, the change from a standby state to a pose holding the gun, the displacement of the athlete P1 or the shotgun 2 following the flying clay, the angular velocity, changes in these over time, and the smoothness of these changes.

[0050] In this embodiment, the body movement analysis unit 112 calculates the body movement of the wearer as body movement data based on the detection results of the wearable sensors 21 and the change characteristics of the circular movement of these wearable sensors 21. At this time, the body movement analysis unit 112 calculates the three-dimensional rotational movement of each wearable sensor 21, as well as the displacement speed, acceleration, angular velocity, angular acceleration, and orientation. Then, the body movement analysis unit 112 sends the calculated characteristic changes of the rotational movement to the acoustic signal generation unit 113 as body movement data.

[0051] The audio signal generator 113 is a module that converts each element of the body movement of the athlete P1, i.e., the change characteristics of the three-dimensional rotational movement included in the athlete P1's movement, into sound based on the body movement data generated by the body movement analyzer 112. In this embodiment, the audio signal is generated as an audio signal that expresses the elements included in the three-dimensional rotational movement analyzed by the body movement analyzer 112, as well as the temporal changes in the displacement speed, acceleration, angular velocity, angular acceleration, and direction, by the pitch, volume, and tone of the sound. The audio signal generated in this manner is displayed or output on the output device via the output interface 102, and the athlete can receive feedback of his or her own movement as sound.

[0052] Specifically, in the analysis by the body movement analysis unit 112, the actions relating to shooting, from the standby state to the ready position, and the actions of tracking the flight of the clay and firing are resolved into a combination of three-dimensional rotational movements into horizontal and vertical components, which are generated as body movement data and input to the audio signal generation unit 113. The audio signal generation unit 113 performs conversions such as expressing the angular velocity, angular acceleration, other accelerations, horizontal movement, etc. of each of these rotational movements with various changes in pitch and tone, expressing strength and weakness with volume, etc.

[0053] 6, the sound signal generator 113 acquires the vertical and horizontal angular accelerations of the shotgun 2, breaks them down into vertical components AaV and horizontal components AaH, and generates sound signal Ss1 by allocating each of these angular acceleration components to predetermined parameters of two types of waveform components, here the wavelengths (frequencies) of each waveform, in a constant ratio and synthesizing them. Note that other analysis methods by the body movement analyzer 112 may include generating stereoscopic data that displays the athlete P1 in three dimensions, or may generate two-dimensional data by projecting the stereoscopic movements onto the XY, YZ, and XZ planes.

[0054] The output signal control unit 114 is a module that generates acoustic information and display information to be output or displayed on the output interface 102, and outputs the body movement data analyzed by the body movement analysis unit 112 as an acoustic signal, or generates display information to be displayed or output in synchronization with a captured video. This display information may display, for example, a video captured by a built-in camera or an external camera 131 on the screen of a smartphone such as the information processing terminal 100, and may display the body movement data analyzed by the body movement analysis unit 112 in a form that is synchronized with a timeline that displays the body movement data in chronological order by expressing the motion parameters, which are components contained in the detection results of various sensors such as angular acceleration, acceleration, and angular velocity, as graphics such as planar figures. Note that this display information includes acoustic signals and other output control signals as well as the display data.

[0055] The training management unit 116 is a functional module that manages the entire shooting training, and is virtually constructed by executing a body movement training program, appropriately processes the data acquired from the detection signal acquisition unit 111 and the image analysis unit 117, records the body movement data analyzed by the body movement analysis unit 112, and manages the entire training.

[0056] Specifically, the body movement analysis unit 112 analyzes the body movement of the athlete P1 from the wearable sensor 21 and video data, and the audio signal generation unit 113 generates an audio signal based on the body movement data and records it as an audio file together with the date and time of training and location information. Video captured by a separate camera or the like may be recorded in association with this audio file.

[0057] The recorded audio files can be selected and played back as needed, and by listening to the playback data, the athlete can memorize and visualize the results of the body movement analysis as audio, allowing the athlete to objectively understand and improve his or her own movements. In addition, while operating this system, the athlete can reproduce his or her own movements along with the audio, allowing the athlete to more effectively master the reproducibility of his or her own movements.

[0058] The training management unit 116 may store model body movement data and audio signals in the memory 120, play the model audio data, and compare it with the body movement data of the wearer to generate improvement data that indicates deviations from normal body movements. Furthermore, by registering user information such as gender, height, weight, and age in advance, analysis may be performed based on each user's information. The training management unit 116 has a function of outputting the analysis results of the stereoscopic image data and the improvement data from the information processing terminal 100 as video, audio, and the like.

[0059] The memory 120 is a storage device that records various types of data, and accumulates identification information that identifies each information processing terminal 100, information on the mounting site of each wearable sensor 21, the relative positional relationship of the wearable sensors 21 mounted on each site, the above-mentioned user information, exemplary body movement data, and the like.

[0060] (Physical Activity Training Method) (1)Outdoor training By operating the physical exercise training system having the above configuration, the physical exercise training method according to this embodiment can be carried out. Figure 3 shows each step of outdoor physical exercise training.

[0061] First, the athlete P1 wears the wearable sensor 21 on a part of the body related to shooting, for example, on an arbitrary part such as an arm, or on a gun, and performs physical movement training. Then, the application, which is the program of the present invention, is started on the information processing terminal 100 side, and a measurement start operation is input to the application to obtain detection results from each wearable sensor 21, and an operation to start shooting with the external camera 131 is performed (S101). In response to this measurement start operation, the output signal control unit 114 of the information processing terminal 100 performs a connection process with each wearable sensor 21. After the connection process is completed, the wearable sensor 21 starts detecting the movement of the athlete P1 (S102). Specifically, the wearable sensor 21 attached to the wearer's body or gun detects three-dimensional displacement or acceleration of each part.

[0062] The acquired detection results are transmitted by weak radio waves to the wireless interfaces 101a, 102a of the information processing terminal 100 via the wireless communication unit of the wearable sensor 21. When the wireless interfaces 101a, 102a of the information processing terminal 100 start acquiring the detection results, the memory 120, which is a body movement recording unit, sequentially records the detection results by the wearable sensor 21 as body movement data.

[0063] Next, when the clay to be used as the target is shot (S103), the athlete P1 moves to track the shot clay, and an audio signal is generated in accordance with the athlete's movement (S104), and the sound is output in real time and recorded as an audio file (S105). In addition, when the athlete fires a shot, the action caused by the shot is also recorded by recording the sound of the shot, detecting vibrations, and taking video (S106).

[0064] In this way, during the competition, the detection values ​​of the worn sensor 21 are continuously obtained and the recording process is continuously executed, and recorded in the memory 120, etc. ("N" in S107). During this time, video data captured by the external camera 131 built into the information processing terminal 100 or the externally connected external camera 131 is obtained by the body movement analysis unit 112, and is stored in the memory 120 or is provided for the body movement analysis process in the output signal control unit 114. At this time, the detection data by the worn sensor 21 and the recorded video may be analyzed in real time and displayed on the display unit of the information processing terminal 100. Thereafter, when the competition is over, the measurement is ended ("Y" in S107), and, as necessary, the recording process is stopped, communication with the sensor is cut off, or other end process is executed (S108).

[0065] (2) Indoor training By operating the physical exercise training system having the above configuration, the physical exercise training method according to the present embodiment can be carried out. Figure 4 shows the specifications for indoor training in the physical exercise training system according to the embodiment, and Figure 5 shows each step of the physical exercise training outdoors.

[0066] As described above, the video and body movement data recorded during outdoor training can be used in indoor training that combines equipment that projects the recorded video on a screen with a laser gun 20, as shown in Fig. 4. As shown in Fig. 4, a projector 132 is connected to the above-mentioned information processing terminal 100, and the captured video of the clay is played back, while an external camera 131 captures an image of a pointer 20a on a screen 133 of the laser irradiated by the laser gun 20, and the image is input to the information processing terminal 100.

[0067] In this system, as described above, the body movements of the athlete P1 are detected by a sensor built into the laser gun 20, and the behavior of the pointer 20a on the screen 133 is photographed by an external camera 131 and analyzed by the body movement analysis unit 112, thereby tracing or capturing the body movements of the athlete P1.

[0068] Then, when body movement data is acquired by the sensor and the detection signal acquisition unit 111, and video data is acquired by the image analysis unit 117 and the body movement analysis unit 112, a body movement calculation process and a body movement analysis process are executed, and an acoustic signal is generated by converting the body movement of the athlete P1 into sound. As a specific procedure, when the live shooting training starts (S201), the projection of the image of the flying clay recorded during the outdoor training starts on the screen 133 (S202), and the light trail of the laser pointer 20a emitted from the laser gun 20 is photographed (S203).

[0069] At this time, data acquisition by the sensor and detection signal acquisition unit 111 and video data acquisition by the image analysis unit 117 and body movement analysis unit 112 are performed simultaneously (S201). These processes work together to form a basis for embodying the body movements of the athlete P1 as audio signals. Specifically, as the live-shooting training begins (S201), an image of a clay flying scene recorded during outdoor training is projected onto the screen 133 (S202). This image reproduces the situation during actual outdoor training for the athlete P1. At the same time, the light trail of the laser pointer 20a emitted from the laser gun 20 is captured by the external camera 131 or other appropriate sensor (S203). This light trail is used as data for tracking the directionality and movement of the athlete P1's gun in detail.

[0070] The captured image of the light trail is acquired by the detection signal acquisition unit 111 and transmitted to the body movement analysis unit 112. Here, specific body movement data such as the movement, angle, and acceleration of the athlete P1's gun are generated. In addition, the image analysis unit 117 analyzes the projected image of the clay, and compares and collates the movement with the body movement data of the athlete P1. The analysis result is transmitted to the sound signal generation unit 113.

[0071] Here, each element of the athlete P1's body movement is converted into sound. Specifically, the changing characteristics of the three-dimensional rotational movement included in the athlete P1's movement are expressed by the pitch, volume, and tone of the sound. The generated sound signal is then displayed or output on the output device through the output interface 102 (S204, S205). This allows the athlete P1 to directly hear his or her own body movement as sound, and understand his or her own movements and their results in real time. In this way, the athlete receives specific feedback of his or her own movements as sound, and is able to find more specific ways to improve.

[0072] In this way, outdoor training is reproduced, and the audio signal obtained at that time is compared with the audio signal output from the indoor training facility, and according to this system, the athlete P1 can correct his / her own movements based on the feedback from both indoor and outdoor training. Specifically, the athlete P1 can visualize the body movements converted into the audio signal, which is the feedback, as sounds, and understand which movements correspond to the changes in the audio signal, thereby identifying the points to correct in his / her own movements and forming a new movement pattern to improve them.

[0073] The system of the present invention then acquires the improved movement of athlete P1 again using the sensor or detection signal acquisition unit 111, and analyzes it using the body movement analysis unit 112. This new movement data is again sent to the audio signal generation unit 113 and converted into an audio signal. As a result, athlete P1 can obtain a new audio signal corresponding to his or her improved movement.

[0074] This feedback loop ("N" in step S208) is repeated, providing a means for the athlete P1 to continually improve his / her own movements and achieve higher performance. Ultimately, the system of the present invention allows the athlete P1 to improve his / her clay shooting skills. During this feedback loop, an image of the clay being shot is displayed on the screen 133. This image reproduces the situation of an actual clay shooting, making it possible to imitate the actual shooting situation in which the athlete P1 tracks the flying clay and takes aim at the appropriate time. When the athlete P1 moves to track the image in response to this shooting, the light trail of the laser pointer 20a changes in accordance with the movement.

[0075] The action of tracking the laser pointer 20a is also converted into an acoustic signal, output, and recorded as part of the feedback loop. The athlete P1 visually checks the image of the clay projected on the screen, and operates the laser gun 20 to track it. This operation action is tracked by the laser pointer 20a, and each element of the athlete P1's body movement, such as the speed and angle at which the athlete P1 moves the gun, and changes in the gun's position, are captured as a light trail from the laser pointer 20a. Then, a firing signal generated by the athlete P1 pulling the trigger is acquired ("Y" in S206) and recorded (S207).

[0076] Furthermore, the outputted acoustic signal is recorded by the memory 120 inside the information processing terminal 100 (S205). This allows the athlete P1 to refer to past acoustic signals in order to re-evaluate his / her performance even after training. This is an important means for self-evaluation and self-improvement.

[0077] In this way, during the competition, the detection values ​​of the worn sensor 21 are continuously obtained and the recording process is continuously executed and recorded in the memory 120, etc. ("N" in S208). Thereafter, when the competition ends, the measurement is stopped ("Y" in S209), and the training management unit 116 and the data control unit 115 record and manage a series of acoustic signals, body movement data, and image data as training results, and execute termination processes such as stopping the recording process and disconnecting communication with the sensor as necessary (S209).

[0078] (Physical Activity Training Program) The physical movement training system and the physical movement training method according to the present embodiment described above can be realized by executing the physical movement training program of the present invention written in a specific language on a computer, like the above-mentioned physical movement training application. That is, the program of the present invention can be installed in an IC chip or memory device of a general-purpose computer such as a portable terminal device, a smartphone, a wearable terminal, a mobile PC or other information processing terminal, a personal computer or a server computer, and executed on a CPU to construct a system having each of the above-mentioned functions and implement the physical movement training method.

[0079] (Action and effect) According to this embodiment, in shooting and other sports, even under extreme tension or stress, a person can learn the technique of reproducing the speed and rhythm of the movements as trained, and training suited to real combat can be realized. More specifically, in this invention, an acceleration sensor attached to a part of the wearer's body or to a portable device detects the body's movements, the rhythm and speed of the movements, and converts them into an audio signal. Based on this audio signal, sound is output from the output means, and the wearer can hear sounds that match his or her own movements, rhythm and speed.

[0080] In this way, this embodiment enables the athlete P1 to effectively train in clay target shooting. Through a series of processes including image display, motion analysis, audio signal generation, and recording, the athlete P1 can understand his / her own motion and its results in detail and improve them. In addition, this system allows the athlete P1 to understand his / her own motion and its results in real time by directly hearing his / her own motion as audio while imitating a real shooting experience, which contributes to the improvement of the athlete P1's shooting technique.

[0081] As a result, through training using this invention, the speed and rhythm of body movements can be memorized and mastered as sound patterns, so that in actual combat, the body movements to be reproduced can be imagined by recalling the sound. By imagining the sound of the mastered pattern and performing movements in accordance with it, the speed and rhythm of movements can be reproduced even under extreme tension or stress.

[0082] Here, the difference between the laser gun 20 of the system according to this embodiment and a conventional laser gun will be described in detail. In the conventional laser gun, the laser irradiation indicates the point of impact, and the main purpose is to judge whether the bullet "hit" or "missed" by emitting the laser at the moment the trigger is pulled. In contrast, in the laser gun 20 of the system according to this embodiment, the laser irradiation continues from the moment the gun is aimed, even before the trigger is pulled.

[0083] Specifically, the system expresses and records the dynamics of how the impact point moved or was affected by the successive gun movements leading up to the shooting of the flying object (clay T1). In addition, the system of this embodiment can visualize the recorded dynamic data of the impact point in the form of a graph or the like, or convert it into sound, so that the athlete P1 can easily grasp the dynamics.

[0084] Therefore, according to this embodiment, in shooting competitions and other sports competitions, not only can trainees acquire the skills to reproduce the speed and rhythm of movements as trained even under extreme tension or stress, realizing training that matches actual combat, but it also enables trainees to objectively understand and improve their own actions and results.

[0085] In target practice, when studying the sequence of gun movements to shoot a flying object, it is important to be aware of the current gun direction, i.e., where the point of impact is. Usually, the point of impact is determined by a protrusion called a "front sight" attached to the end of the gun barrel. However, this method is quite rough, and it is difficult for the shooter to recognize changes in the point of impact, especially due to momentary movements. In contrast, the system according to the present embodiment uses laser irradiation and data analysis from high-speed video to enable the shooter to more accurately recognize the dynamics of the point of impact.

[0086] The system according to this embodiment can also convert the movement of the impact point into visual data and further convert it into sound. The visual data is displayed using a graph or the like, and the movement of the impact point is converted into auditory data such as pitch to convert it into sound. This information is provided to the shooter through an appropriate output means (e.g., earphones), so that the shooter can instantly understand the movement of the impact point caused by his or her own movements.

[0087] With these characteristics, the system according to the present embodiment can significantly improve the efficiency and accuracy of shooting training. The shooter can acquire the technique to reproduce the speed and rhythm of the movements as trained even under extreme tension and stress, enabling more realistic training, while at the same time enabling the shooter to objectively understand and improve his / her own actions and their results.

[0088] The degree of the effect of time lag changes relative to the projectile and the "state of the shot at the time of firing." The "state of the shot at the time of firing" is determined by the dynamics of how the point of impact is moved or affected by the successive gun movements made to shoot the projectile.

[0089] Research and improvement of these dynamics are the main elements of training. However, current clay shooting athletes rely on intuition and experience to recognize these dynamics, which requires a large amount of actual shooting. For this reason, the cost of training is a major obstacle to the development of clay shooting.

[0090] The present invention provides a method to address this problem. The present invention converts dynamics into visual and audio, allowing trainees to easily recognize dynamics. In addition, trainees can train indoors without actually shooting bullets, so the focus of clay target shooting practice will be significantly shifted from a shooting range that requires a large amount of live shooting to indoor practice.

[0091] This physical training system can be applied not only to shooting competitions but also to other sports and athletic competitions. For example, in gymnastics, the athlete's movements can be adjusted accurately by outputting sounds that match the rhythm of jumps and rotations, and in dance competitions, the athlete can adjust his or her movements while being conscious of the rhythm of the music. This system can provide a very useful training tool for athletes who want to acquire accurate techniques and rhythms in sports and athletic competitions.

[0092] In addition, the physical movement training program according to this embodiment can be distributed, for example, via a communication line, and can be transferred as a package application that runs on a stand-alone computer by recording it on a computer-readable recording medium.

[0093] Specifically, the program can be recorded on various recording media, including magnetic recording media such as flexible disks and cassette tapes, optical disks such as CD-ROMs and DVD-ROMs, and RAM cards. A computer-readable recording medium on which the program is recorded makes it possible to easily implement the above-mentioned system and method using a general-purpose computer or a dedicated computer, and also makes it easy to store, transport, and install the program.

[0094] The present invention is not limited to the above-described embodiments, and the components can be modified without departing from the spirit of the invention. Various inventions can be created by appropriately combining the components disclosed in the above-described embodiments. For example, some components may be deleted from all the components shown in the embodiments. [Explanation of symbols]
