[Functional configuration]
FIG. 5 is a functional block diagram showing a functional configuration for executing information detection processing among the functional configurations of the sensor unit 1.
The information detection process is a series of processes in which the sensor unit 1 mounted on the measurement target senses the movement of the measurement target when the analysis system S analyzes the movement of the measurement target.
When the information detection process is executed, as shown in FIG. 5, the communication control unit 151, the calibration execution unit 152, the detection processing unit 153, and the sensor information transmission control unit 154 function in the CPU 111.
Further, a sensor information storage unit 171 is set in one area of the storage unit 119.
The sensor information storage unit 171 stores the sensor information acquired by the sensor unit 1 in association with the acquired time.

The communication control unit 151 controls communication by the BLE of the sensor unit 1 and executes pairing processing with other devices and data transmission / reception processing.

The calibration execution unit 152 acquires sensor information in a reference state in response to an instruction from the processing device 2, and executes calibration using the acquisition result as a reference value. In the present embodiment, the calibration execution unit 152 is based on a state in which the sensor unit 1 is attached to the waist of the measurement target person P and takes a posture addressed to a position for performing a golf swing, and in this state. The acquired sensor information is used as a reference value.

FIG. 6A is a schematic diagram showing a mounted state of the sensor unit 1, and FIG. 6B is a schematic diagram showing an example of information detected by the sensor unit 1. In the following description, for each axis set in the sensor unit 1, the forward tilt direction of the measurement target person P is plus for the rotation in the front-back direction, and the follow direction of the measurement target person P for the rotation around the vertical axis. Plus, for rotation in the left-right direction, the direction in which the follower side of the measurement target person P is higher is the plus. For parallel movement in the front-back direction, the front of the measurement target person P is plus, for parallel movement in the vertical direction, the upper side of the measurement target person P is plus, and for parallel movement in the left-right direction, the follow direction of the measurement target person P is plus. And.

When calibration is performed, as shown in FIG. 6A, for example, the sensor unit 1 is attached to the waist of the measurement target person P by a belt or the like, and the measurement target person P is placed on the ball at a position for performing a golf swing. Stand still for a predetermined time (for example, 2 seconds) in the opposite posture. At this time, as shown in FIG. 6B, the sensor unit 1 has sensor information (tilt angle in the front-back direction of the body, with reference to the gravity direction detected by the 3-axis acceleration sensor and the orientation detected by the 3-axis geomagnetic sensor. The tilt angle in the left-right direction and the rotation angle around the vertical axis) are acquired, and each acquired sensor information is used as a reference value at the time of addressing. After that, when the measurement target person P swings, each sensor information detected in the sensor unit 1 is set for each sensor information with respect to the reference value at the time of address for a predetermined time (for example, 2 seconds) or more. If it is within the range of the threshold value, it is detected as the state of the address.
Further, since the sensor unit 1 is provided with a 3-axis acceleration sensor, it is possible to detect the movement (parallel movement, etc.) of the sensor unit 1, and since it is equipped with a 3-axis geomagnetic sensor, the sensor unit 1 is suitable. It is also possible to detect the direction in which it is located.

When the calibration execution unit 152 executes the calibration, the reference value may be acquired while the measurement target person P is upright.
For example, the sensor unit 1 is attached to the waist of the measurement target person P by a belt or the like, and the measurement target person P stands still for a predetermined time (for example, 2 seconds) in an upright posture facing the ball at a position for performing a golf swing. .. At this time, the sensor unit 1 refers to the sensor information (tilt angle in the front-rear direction of the body, tilt angle in the left-right direction, and vertical direction) with reference to the gravity direction detected by the 3-axis acceleration sensor and the orientation detected by the 3-axis geomagnetic sensor. (Rotation angle around the axis) is acquired, and each acquired sensor information is used as a reference value when standing upright. After that, when the measurement target person P swings, each sensor information detected in the sensor unit 1 is set for each sensor information with respect to the reference value when standing upright for a predetermined time (for example, 2 seconds) or more. When it is within the range of the threshold value corresponding to the posture at the time of addressing, it is detected as the state of the address.

The detection processing unit 153 sequentially acquires various sensor information, and stores the acquired sensor information in the sensor information storage unit 171 in association with the acquired time. The sensor information stored in the sensor information storage unit 171 may be sequentially discarded when a predetermined time has elapsed from the acquired time. However, the sensor information acquired from the address of the golf swing to the end of the swing is discarded at least after the transmission to the processing device 2 is completed.
Further, the detection processing unit 153 detects the timing of a predetermined characteristic point in the golf swing based on the acquired sensor information. For example, the detection processing unit 153 analyzes the waveform of the acquired sensor information, and detects the timing of each point of the address, top, downswing, impact, and follow in the golf swing.
In addition to detecting the timing of each point in the golf swing as described above, the period corresponding to each point may be directly detected.

Further, when the detection processing unit 153 detects the timing of the address and the timing of the follow, the signal indicating that the timing of the address is detected (hereinafter referred to as "address detection signal") and the follow. A signal indicating that the timing has been detected (hereinafter, referred to as a “follow detection signal”) is sequentially transmitted to the processing device 2 by the BLE.

The sensor information transmission control unit 154 controls to transmit the sensor information acquired by the detection processing unit 153 to the processing device 2. In the present embodiment, the detection processing unit 153 can acquire sensor information at, for example, about 1000 samples / second. Then, the sensor information transmission control unit 154 converts the sensor information acquired by the detection processing unit 153 into a preset sampling rate (for example, about 240 samples / sec) and transmits the sensor information to the processing device 2. In the present embodiment, the sensor information in the range from the address to the follow of the golf swing of the measurement target person P is transmitted to the processing device 2.

Further, when the sensor information transmission control unit 154 transmits the sensor information to the processing device 2, the address, top, downswing, impact, and follow points detected by the detection processing unit 153 (characteristic of a golf swing). The timing of point) is also transmitted to the processing device 2.
In the present embodiment, the sensor information acquired by the detection processing unit 153 is converted into a waveform in which the influence of noise is suppressed by filtering the output signals of various sensors, respectively, and the sensor information transmission control unit 154 determines. The sensor information acquired from the waveform represented by the sensor information of the processing result is transmitted to the processing device 2.
Thereby, it is possible to evaluate the movement of the measurement target person P by referring to the information having higher reliability than the sensor information having a large variation due to the influence of noise.

Next, the functional configuration of the processing device 2 will be described.
FIG. 7 is a functional block diagram showing a functional configuration for executing the evaluation result display processing among the functional configurations of the processing device 2.
The evaluation result display process analyzes the sensor information detected by the sensor unit 1 and analyzes the characteristics of the measurement target person P in the golf swing (rotational speed of the waist, angle of the waist, movement amount of the waist, swing rhythm, total). Evaluation, etc.) is acquired, and the acquired features are displayed as the evaluation result of the swing of the measurement target person P using numerical values and figures.
When the evaluation result display process is executed, as shown in FIG. 7, in the CPU 211, the communication control unit 251, the calibration management unit 252, the sensor information acquisition unit 253, the swing evaluation unit 254, and the display control unit 255 are executed. And the recording control unit 256 function.
Further, a sensor information storage unit 271, a reference data storage unit 272, and an evaluation result storage unit 273 are set in one area of the storage unit 220.

The reference data storage unit 272 stores data that is referred to as a reference when evaluating a swing, such as statistical data (average value, etc.) regarding the swing of an advanced golfer and data of a good swing of the measurement target person P himself. Will be done.
FIG. 8 is a schematic diagram showing an example of swing data in an advanced golfer (professional golfers P1 to P7). Further, FIG. 9 is a schematic diagram showing an example of swing data for beginners and intermediate golfers (amateurs A1 to A7).
As shown in FIG. 8, in a swing in an advanced golfer, two large peaks tend to appear in the waveform of the angular acceleration of the hip. This means that in the case of an advanced person, the rotation of the waist is stopped once during the swing, and this operation makes it easy to increase the rotation speed of the waist. Further, referring to FIGS. 8 and 9, the maximum angular velocity of hip rotation is 530 [degrees / sec] on average for advanced golfers (professional golfers), whereas it is for beginners and intermediate golfers. In the case of a person (amateur), the average is 480 [degrees / sec]. In addition, the average angular acceleration from the top posture to the maximum rotation speed of the waist is 2500 [degrees / sec ² ] on average for advanced golfers, whereas it is for beginners and intermediate golfers. In the case of a person, the average is 1700 [degrees / sec ² ]. In addition, the rotation angle of the waist in the top posture is -60 [degrees] on average for advanced golfers, whereas it is -70 [degrees] on average for beginners and intermediate golfers. ]. From these tendencies, it is judged that beginners and intermediate golfers are significantly different from advanced golfers in that the angular acceleration of the waist is particularly small and it takes time to reach the maximum rotation speed. be able to. In other words, there is a big difference in how to use the hips when comparing advanced golfers with beginners and intermediate golfers, and beginners and intermediate golfers can improve their golf swing by improving how to use the hips. can.
Returning to FIG. 7, the evaluation result storage unit 273 stores information regarding the evaluation result of the measurement target person P generated in the evaluation result display process.

The communication control unit 251 controls communication by the BLE of the processing device 2, and executes pairing processing with other devices and data transmission / reception processing. In the present embodiment, when communication by BLE is performed, the processing device 2 becomes the master and the other device becomes the slave.

The calibration management unit 252 instructs the sensor unit 1 to execute the calibration. In the present embodiment, the calibration in the sensor unit 1 is executed once when the evaluation result display process is executed.

The sensor information acquisition unit 253 acquires the sensor information of the preset sampling rate from the sensor unit 1 by BLE. In the present embodiment, the sensor information acquisition unit 253 acquires sensor information in the range from the address to the follow of the golf swing of the measurement target person P from the sensor unit 1. Information that identifies each point of address, top, downswing, impact, and follow is added to the sensor information acquired at this time.

The swing evaluation unit 254 analyzes various sensor information acquired from the sensor unit 1, and features the golf swing of the measurement target person P (waist rotation speed, waist angle, waist movement amount, swing rhythm, comprehensive). Acquire data representing (evaluation, etc.) (hereinafter referred to as "evaluation result data").
At this time, the swing evaluation unit 254 integrates the detected values of the 3-axis acceleration sensor to calculate the movement amount (distance), differentiates the detected values of the 3-axis angular velocity sensor to calculate the rotational angular acceleration, and 3 The rotation angle is calculated by integrating the detected values of the axial angular velocity sensor.
In the present embodiment, the swing evaluation unit 254 can acquire various data related to the swing that can be acquired from the sensor information, and among these, necessary data can be used as the swing evaluation result data.

The display control unit 255 displays a guidance screen for measuring the swing of the measurement target person P. This guidance screen includes a message prompting an action such as "please address" and "please perform a swing", and a message notifying the situation such as "analyzing the swing".
Further, the display control unit 255 displays a screen (hereinafter, referred to as “evaluation result display screen”) showing the evaluation result of the swing of the measurement target person P based on the evaluation result data acquired by the swing evaluation unit 254. do. When the evaluation result display screen is displayed, buttons for displaying the rotation speed of the waist, the angle of the waist, the amount of movement of the waist, the swing rhythm, and the comprehensive evaluation are displayed on the menu screen. Then, when the user operates any of the buttons, an evaluation result display screen displaying each feature is displayed.

FIG. 10 is a schematic diagram showing an example of an evaluation result display screen.
As shown in FIG. 10, as the evaluation result display screen, a rotation speed display screen that displays features related to the rotation speed of the waist, an angle display screen that displays the features related to the angle of the waist, and a movement amount that displays the features related to the movement amount of the waist. A display screen, a swing rhythm display screen that displays features related to swing rhythm, and a comprehensive evaluation display screen that displays features related to comprehensive evaluation can be selected.

The rotation speed display screen is a display screen that includes a numerical value indicating the rotation speed (rotational speed) of the waist, the time required to reach the maximum rotation speed of the waist from the top posture, and a graph showing the time change of the rotation speed of the waist. be.
The angle display screen is a display screen including a forward tilt angle, a rotation angle, a numerical value representing a horizontal angle at each point in the swing, a maximum value, a minimum value, a change width, and the like.

In the present embodiment, the indicator on the movement amount display screen gradually represents the deviation of the swing of the measurement target person P with respect to the statistical data based on the average of the swings of a predetermined number or more of advanced players (male and female professional golfers, etc.). ing.

The swing rhythm display screen is a display screen including numerical values indicating the elapsed time for each point (time required between points) in the swing.
The comprehensive evaluation display screen is a display screen including a radar chart showing the result of evaluating the swing of the measurement target person P by a score for each evaluation item, a numerical value representing the score, and the like.

Of these display screens, the rotation speed display screen displays a graph related to the rotation speed of the waist.
FIG. 11 is a schematic diagram showing an example of a rotation speed display screen.
As shown in FIG. 11, the rotation speed display screen has an area R1 for displaying the maximum value of the rotation speed (rotational speed) of the waist, and an area R2 for displaying the time required to reach the maximum rotation speed of the waist from the top posture. A region R3 of a graph showing the time change of the rotation speed of the waist and a region R4 of displaying the potential (potential flight distance) of the flight distance of the measurement target person P are included. The potential flight distance is calculated by a statistical method (taking an average value, etc.) from the flight distances of a plurality of players whose swing data is close to the measurement target person P.

As mentioned above, there is a big difference in how to use the waist between advanced and beginners and intermediate golfers, and when looking at the time change (graph) of the rotation speed of the waist, the waveform of the rotation speed of the waist is generally , As the golf progresses, it changes in the order of mountain range type, one mountain type, and lid mountain type.
The lid mountain type is a type of swing in which the waveform of the rotation speed of the waist is clearly divided into a mountain (two large mountains) having a peak in the first half and a peak in the second half, and a valley between them. It is a type that can be seen by people. That is, for advanced users, the rotation of the waist is stopped once during the swing, and this operation makes it easy to increase the rotation speed of the waist.

The one-mountain type is a type of swing in which the waveform of the rotation speed of the waist is generally a mountain having one peak (one large mountain). In the case of a one-mountain swing, it means that the hips are rotating, but the rotation speed is slow or the hips cannot be moved efficiently, and as a result of the one-mountain swing, weight transfer is smooth. It becomes difficult to do.

The mountain range type is a type of swing in which the waveform of the rotation speed of the waist is a series of small mountains. In the case of a mountain range type swing, it means that the waist does not rotate smoothly from the top to the impact, and in the case of hand striking or swaying, it is a mountain range type swing.
The measurement target person P who has confirmed the rotation speed display screen can visually determine which type his / her swing corresponds to.

Further, in the present embodiment, when a predetermined operation (for example, an operation of an icon for displaying advice) is performed, the display control unit 255 describes the type of these swings and improves the swing according to the type. A screen (hereinafter referred to as "method presentation screen") for presenting the method and the method as support information for the user is displayed. On the method display screen, the display control unit 255 displays, for example, swing improvement points and training for improving the swing as support information.

FIG. 12 is a schematic diagram showing an example of the display contents of the method presentation screen.
As shown in FIG. 12, on the method presentation screen, the type of the waveform of the rotation speed of the waist of the measurement target person P (the lid mountain type, the one mountain type, and the mountain type) and the approximate evaluation result of the rotation speed of the waist (the highest). The rotation speed, the time it takes to reach the maximum rotation speed of the waist from the top posture, and the evaluation of ○, ×, and △ regarding the appearance of two large mountains) and the support information for each type are displayed. For the lid mountain type swing, support information for further improving the swing is displayed, and in the example of FIG. 12, the time to reach the maximum rotation speed of the waist from the top posture should be shortened, and The comment of the advice for that is displayed. In addition, for the one-mountain-shaped swing, support information to the effect that it should be a two-mountain-shaped swing and comments on advice for that are displayed. In addition, in the example of FIG. 12, the improvement drill for training the body is also displayed for the one-mountain type swing. Further, for the mountain range type swing, support information to the effect that it should be a mountain range type swing and advice information for that are displayed.

The content of the method presentation screen can be stored in the processing device 2 or stored as a link to an external device and downloaded from a predetermined content server or the like. Further, the content of the method presentation screen may be output by voice. As a result, the measurement target person P who is swinging can more easily grasp the display content.

Further, on the movement amount display screen, an indicator showing the magnitude (movement degree) of the movement amount in the vertical direction, the horizontal direction, and the front-back direction between each point in the swing is displayed.
FIG. 13 is a schematic diagram showing an example of a movement amount display screen.
As shown in FIG. 13, on the movement amount display screen, the degree of each of the left-right movement amount, the up-down movement amount, and the front-back movement amount (deviation with respect to the reference swing) is 5 for the swing of the measurement target person P. It is represented by the indicator In of the stage.

FIG. 14 is a schematic diagram showing the relationship between the indicator and the deviation.
Note that x1 to x12, y1 to y12, and z1 to z12 in FIG. 14 indicate boundary values of the degree of movement amount.
As shown in FIG. 14, when the movement amount display screen is displayed, the movement amount of the waist at each point of address-top, top-front, front-finish is statistical data in each item of left / right, front / back, and up / down. It is classified according to how much deviation it has. Then, the indicator to be identified and displayed on the movement amount display screen is determined according to the classified deviation range (the range corresponding to the indicators A to E arranged from the minus side to the plus side). In FIG. 14, the central indicator C corresponds to the range including the “mean value”, and the range of the indicator C is set to the value represented by the “deviation”.

In addition, as statistical data that serves as a reference when calculating the deviation of the measurement target person P, the average value of all advanced players above a predetermined number can be used, and draw-type players, fade-type players, male professional golfers, and female professional golfers can be used. It is possible to use the average value for each model according to the type of club to be used. It is also possible to use the past swing of the person to be measured P as a reference, which is judged to be a good swing.

The recording control unit 256 stores the swing evaluation result data acquired by the swing evaluation unit 254 in the evaluation result storage unit 273 or the removable media 231. The recording control unit 256 executes the storage of the evaluation result data when the operation for instructing the storage of the evaluation result data is performed.

A graph or the like representing the above is displayed.
Therefore, it is possible to visually and easily display the type of how to use the waist, which is important for improving golf, and it is possible to accurately grasp the degree of improvement of the swing of the measurement target person P.
Therefore, it is possible to more appropriately determine the quality of the movement of the measurement target person P based on the sensor information (angular velocity, etc.) at the waist of the measurement target person P.

Further, among the evaluation result display screens, in particular, on the movement amount display screen, indicators and the like indicating the magnitude (movement degree) of the movement amount in the vertical direction, the horizontal direction, and the front-back direction between each point in the swing are displayed. .. The indicator on the movement amount display screen represents the deviation of the swing of the measurement target person P with respect to the statistical data based on the average of the swings of a predetermined number or more of advanced players (male and female professional golfers, etc.).
Therefore, regarding the difference between the swing of the measurement target person P and the swing of the advanced person, what is the amount of movement of the waist at each point of address-top, top-front, front-finish in each item of left / right, front / back, and up / down? It is possible to visually and easily display whether or not there is a degree of deviation.
Therefore, it is possible to more appropriately evaluate the quality of the movement of the measurement target person P based on the measured value of the sensor attached to the waist of the measurement target person P.
As described above, according to the analysis system S in the present embodiment, it is possible to more appropriately evaluate the quality of the movement of the measurement target person P.
When evaluating the quality of the movement of the measurement target person P, the difference between the waist movement amount of the measurement target person P and a predetermined value such as a reference statistical data, for example, an average value of the waist movement amount of an advanced person. The smaller the difference, the higher the evaluation of the movement of the measurement target person P.

[Modification 1]
In the above-described embodiment, when the evaluation result of the swing of the measurement target person P is displayed on the evaluation result display screen, an animation showing the characteristics of the swing of the measurement target person P may be displayed.

As a result, the characteristics of the measurement target person P in the swing can be clearly displayed.
When displaying this animation, the characteristics of the measurement target person P in the swing may be exaggerated and displayed.
In addition to the animation, a numerical value indicating the amount of movement of the waist may be displayed.

The processing device 2 configured as described above has a swing evaluation unit 254.
The swing evaluation unit 254 calculates the amount of movement of the waist of the measurement target person P based on the measured value measured by the sensor unit 1 mounted on the waist of the measurement target person P.
The swing evaluation unit 254 evaluates the movement of the measurement target person P based on the waist movement amount of the measurement target person P calculated by the swing evaluation unit 254.
Thereby, it is possible to more appropriately evaluate the quality of the movement of the measurement target person P based on the measured value of the sensor attached to the waist of the measurement target person P.

The swing evaluation unit 254 calculates the waist movement amount of the measurement target person P for each predetermined direction based on the measured value measured by the sensor unit 1.
As a result, the amount of movement of the lumbar region is calculated according to a certain standard of a predetermined direction, so that the standard of evaluation can be fixed.

The predetermined direction includes a left-right direction, a vertical direction, or a front-back direction.
This makes it possible to evaluate the movement that affects the amount of movement of the waist in the left-right direction, the up-down direction, or the front-back direction. For example, the swing evaluation unit 254 can calculate and evaluate the amount of movement of the waist in all three directions of the left-right direction, the up-down direction, and the front-back direction, and can perform evaluation in at least one direction (that is, the left-right direction, up-down direction). It is also possible to calculate and evaluate the amount of movement of the lumbar region in terms of the evaluation result in the direction or the anteroposterior direction).

The swing evaluation unit 254 calculates the waist movement amount of the measurement target person P based on the measured values of the acceleration and the angular velocity measured by the sensor unit 1.
As a result, the lumbar movement amount can be calculated with higher accuracy by calculation using both different measured values of acceleration and angular velocity.

The swing evaluation unit 254 evaluates the movement of the measurement target person P by comparing the difference between the waist movement amount of the measurement target person P calculated by the swing evaluation unit 254 and a predetermined value.
Thereby, for example, the swing evaluation unit 254 can evaluate according to the difference from the predetermined value.

The predetermined value is an average value of the amount of movement of the waist of a plurality of measurement subjects P.
As a result, it is possible to make an evaluation based on the amount of movement of the waist other than the person P to be measured this time.

The swing evaluation unit 254 considers the movement of the measurement target person P to be highly evaluated as the difference between the waist movement amount of the measurement target person P calculated by the swing evaluation unit 254 and the predetermined value is smaller.
As a result, for example, when the predetermined value is set as a value related to the waist movement amount of the advanced person, the swing evaluation unit 254 evaluates higher (that is, the evaluation that the difference from the advanced person is smaller) as the difference between the predetermined values is smaller. Can be evaluated as.

The swing evaluation unit 254 evaluates the movement of the measurement target person P by classification according to the deviation of the waist movement amount of the measurement target person P calculated by the swing evaluation unit 254 with respect to the average value of the waist movement amount of a plurality of users. do.
Thereby, for example, when the average value of the waist movement amount of a plurality of users is set as the ideal swing, how close to the ideal swing can be evaluated step by step by classification.

The swing evaluation unit 254 evaluates the movement of the measurement target person P for each predetermined section.
As a result, the swing evaluation unit 254 can evaluate not only the entire movement of the measurement target person P but also each predetermined section.

The swing evaluation unit 254 detects a plurality of predetermined points in the movement of the measurement target person P, and detects the predetermined points.
The predetermined section is between the predetermined plurality of points detected by the swing evaluation unit 254.
As a result, the swing evaluation unit 254 can perform evaluation for each of a plurality of predetermined points. For example, when evaluating a golf swing, the swing evaluation unit 254 may evaluate each point between the address and the top, the top and the front, and the front and the finish, and at least one of the points. Evaluation can also be done.

The processing device 2 further includes a display control unit 255.
The display control unit 255 notifies the evaluation result of the movement of the measurement target person P evaluated by the swing evaluation unit 254.
As a result, the measurement target person P can grasp the evaluation result of his / her own movement.

The display control unit 255 notifies the waist movement amount of the measurement target person P calculated by the swing evaluation unit 254.
As a result, the measurement target person P can grasp the waist movement amount of the measurement target person P calculated by the swing evaluation unit 254 in addition to the evaluation result of his / her own movement.
