[ functional Structure ]

Fig. 5 is a functional block diagram showing a functional configuration for executing information detection processing among the functional configurations of the sensor assembly 1.

The information detection process is a series of processes in which the sensor unit 1 provided in the measurement object senses the motion of the measurement object when the analysis system S analyzes the motion of the measurement object.

When the information detection process is executed, as shown in fig. 5, the CPU111 functions as a communication control unit 151, a calibration execution unit 152, a detection processing unit 153, and a sensor information transmission control unit 154.

In addition, a sensor information storage unit 171 is provided 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 BLE-based communication of the sensor unit 1, and executes pairing processing with another device and data transmission/reception processing.

The calibration execution unit 152 acquires sensor information in a reference state in accordance with an instruction from the processing device 2, and executes calibration with the acquisition result as a reference value. In the present embodiment, the sensor unit 1 is mounted on the waist of the measurement target person P, and the calibration executing unit 152 uses, as a reference, a state in which the posture of the address is taken at a position for performing a golf swing, and uses the sensor information obtained in this state as a reference value.

Fig. 6A is a schematic diagram showing the equipment state of the sensor assembly 1, and fig. 6B is a schematic diagram showing an example of information detected by the sensor assembly 1. In the following description, the rotation of each axis set in the sensor unit 1 in the front-rear direction is positive in the forward tilting direction of the measurement target person P, the rotation around the vertical axis is positive in the feed direction of the measurement target person P, and the rotation in the left-right direction is positive in the direction in which the waist of the measurement target person P on the feed side becomes higher. The parallel movement in the front-rear direction is positive with respect to the front of the person P to be measured, the parallel movement in the up-down direction is positive with respect to the upper side of the person P to be measured, and the parallel movement in the left-right direction is positive with respect to the feed direction of the person P to be measured.

In the case of performing calibration, as shown in fig. 6A, the sensor assembly 1 is attached to the waist of the measurement target person P by a belt or the like, for example, and the measurement target person P is stationary for a given time (for example, 2 seconds) in a posture in which the ball is addressed toward the ball at a position for performing a golf swing. At this time, as shown in fig. 6B, the sensor unit 1 acquires sensor information (the tilt angle of the body in the front-back direction, the tilt angle of the body in the left-right direction, and the rotation angle about the vertical axis) with reference to the gravity direction detected by the 3-axis acceleration sensor and the orientation detected by the 3-axis magnetic sensor, and sets the acquired sensor information as a reference value for the address of the ball. Then, when the measurement target person P swings later, if the sensor information detected by the sensor unit 1 is within a range of a predetermined time (for example, 2 seconds) or more from the reference value at the time of address of the ball to the threshold value set for the sensor information, it is detected that the ball is addressed.

Further, since the sensor unit 1 includes the 3-axis acceleration sensor, it is also possible to detect the movement (parallel movement, etc.) of the sensor unit 1, and since the 3-axis magnetic sensor is provided, it is also possible to detect the azimuth to which the sensor unit 1 is directed.

When the calibration execution unit 152 executes the calibration, the measurement target person P may acquire the reference value while standing upright.

For example, the sensor assembly 1 is equipped to the waist of the measurement target person P by a belt or the like, and the measurement target person P is stationary for a given time (for example, 2 seconds) in a posture standing toward the ball at a position for taking a swing of golf. At this time, the sensor unit 1 acquires sensor information (an inclination angle of the body in the front-rear direction, an inclination angle of the body in the left-right direction, and a rotation angle around the vertical axis) with reference to the gravity direction detected by the 3-axis acceleration sensor and the azimuth detected by the 3-axis magnetic sensor, and sets the acquired sensor information as a reference value when standing upright. Then, when the sensor unit 1 or each piece of detected sensor information becomes equal to or longer than a predetermined time (for example, 2 seconds) within a range in which the reference value at the time of standing corresponds to the threshold value corresponding to the posture at the time of address set for each piece of sensor information when the measurement target person P swings, it is detected that the state is the address state.

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. Further, the sensor information stored in the sensor information storage unit 171 may be discarded in sequence when a predetermined time has elapsed from the time of acquisition. 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 means 2 is completed.

Further, the detection processing section 153 detects the timing of a given 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 address, top swing, bottom swing, hitting, and club feed in the golf swing.

Further, not only the timing of each point in the golf swing as described above, but also the period corresponding to each point may be directly detected.

When the timing of the address is detected and when the timing of the feed lever is detected, the detection processing unit 153 sequentially transmits a signal indicating the timing of the detection of the address (hereinafter referred to as "address detection signal") and a signal indicating the timing of the detection of the feed lever (hereinafter referred to as "feed lever detection signal") to the processing device 2 via BLE.

The sensor information transmission control unit 154 performs control of transmitting 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 a rate of 1000 samples/second, for example. The sensor information transmission control unit 154 then converts the sensor information acquired by the detection processing unit 153 into a preset sampling rate (for example, about 240 samples/second) and transmits the converted sensor information to the processing device 2. In the present embodiment, sensor information for measuring a range from address to swing in the golf swing of the subject person P is transmitted to the processing device 2.

When the sensor information is transmitted to the processing device 2, the sensor information transmission control unit 154 transmits the timing of each point of address, backswing, downswing, batting, and backswing (characteristic point in the golf swing) detected by the detection processing unit 153 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 the various sensors, and the sensor information transmission control unit 154 transmits the sensor information acquired from the waveform represented by the sensor information of the processing result to the processing device 2.

Thus, the movement of the measurement target person P can be evaluated with reference to information having higher reliability than sensor information having a large variation due to the influence of noise.

The functional configuration of the processing device 2 will be described next.

Fig. 7 is a functional block diagram showing a functional configuration for executing evaluation result display processing among the functional configurations of the processing device 2.

The evaluation result display processing is a series of processing as follows: the sensor information detected by the sensor unit 1 is analyzed to obtain characteristics (rotation speed of waist, angle of waist, amount of movement of waist, swing tempo, comprehensive evaluation, etc.) in the golf swing of the measurement target person P, and the obtained characteristics are displayed as evaluation results of the golf swing of the measurement target person P using numerical values and graphs.

When the evaluation result display process is executed, as shown in fig. 7, the CPU211 functions as a communication control unit 251, a calibration management unit 252, a sensor information acquisition unit 253, a swing evaluation unit 254, a display control unit 255, and a recording control unit 256.

In addition, the sensor information storage unit 271, the reference data storage unit 272, and the evaluation result storage unit 273 are set in one area of the storage unit 220.

The sensor information storage unit 271 stores the sensor information for each swing transmitted from the sensor unit 1 in association with the timing of acquiring the sensor information.

The reference data storage unit 272 stores data to be used as a reference for evaluating a swing, such as statistical data (average value and the like) on the swing of a high-level person in golf, and data on a good swing of the measurement target person P.

Fig. 8 is a schematic diagram showing an example of data representing a swing among high-ranking golfers (professional golfers P1 to P7). Fig. 9 is a schematic diagram showing an example of data representing swings of the first-class and middle-class players (amateurs a1 to a7) of golf.

As shown in fig. 8, the swing among the senior golfers tends to have 2 large peaks in the waveform of the rotational angular acceleration of the waist. This means that, in the case of a senior level, the rotation of the waist is stopped once during the swing, and the rotation speed of the waist can be easily increased by this operation. Referring to fig. 8 and 9, the maximum angular velocity of the rotation of the waist is 530[ degrees/sec ] on average in the case of a high-ranking golfer (professional golfer) of golf, while it is 480[ degrees/sec ] on average in the case of a first-ranking golfer and a middle-ranking golfer (amateur golfer) of golf. The average angular acceleration from the stance of the driver to the maximum rotation speed of the waist is 2500[ degree/sec 2] on average in the case of the high-ranked level of golf, while 1700[ degree/sec 2] on average in the case of the first-ranked level and the middle-ranked level of golf. The rotation angle of the waist in the stance of the driver is-60 degrees on average in the case of the high-ranked golf player, while it is-70 degrees on average in the case of the first-ranked golf player and the middle-ranked golf player. From these tendencies, in the case of the first-class level and the middle-class level of golf, it can be determined that the rotation angular acceleration of the waist is small and the time required to reach the maximum rotation speed is greatly different from that of the high-class level. That is, if the high-ranking level person of golf has a large difference in the way of using the waist compared with the low-ranking level person and the middle-ranking level person, the low-ranking level person and the middle-ranking level person can improve the way of using the waist, and thus can improve the golf swing.

Returning to fig. 7, the evaluation result storage 273 stores information about the evaluation result of the measurement target person P generated in the evaluation result display processing.

The communication control unit 251 controls BLE-based communication of the processing device 2, and executes pairing processing with another device and data transmission/reception processing. In the present embodiment, when communication by BLE is performed, the processing device 2 serves as a master and the other devices serve as slaves.

The calibration management section 252 instructs the sensor module 1 to perform calibration. In the present embodiment, the calibration in the sensor unit 1 is performed once at the time of execution of the evaluation result display processing.

The sensor information acquisition unit 253 acquires sensor information at a preset sampling rate from the sensor unit 1 via BLE. In the present embodiment, the sensor information acquiring unit 253 acquires sensor information in a range from address to drive in the swing of the golf of the measurement target person P from the sensor unit 1. The sensor information acquired at this time is added with information for identifying each point of the address, the backswing, the downswing, the batting, and the backswing.

The swing evaluation unit 254 analyzes various sensor information acquired from the sensor unit 1, and acquires data (hereinafter referred to as "evaluation result data") representing characteristics (such as the rotation speed of the waist, the angle of the waist, the movement amount of the waist, the swing tempo, and the overall evaluation) of the golf swing of the measurement target person P.

At this time, the swing evaluation unit 254 calculates the movement amount (distance) by integrating the detection value of the 3-axis acceleration sensor, calculates the rotational angular acceleration by differentiating the detection value of the 3-axis angular velocity sensor, or calculates the rotational angle by integrating the detection value of the 3-axis angular velocity sensor.

In the present embodiment, the swing evaluation unit 254 can acquire various data relating to the swing that can be acquired from the sensor information, and can use necessary data among them as evaluation result data of the swing.

The display control unit 255 displays a guidance screen for measuring the swing of the measurement target person P. The guidance screen includes a message prompting an action such as "address a ball", "please swing a stick", and a message notifying a situation such as "being hit during swing analysis".

The display control unit 255 displays a screen representing the evaluation result of the swing of the measurement target person P (hereinafter referred to as "evaluation result display screen") based on the evaluation result data acquired by the swing evaluation unit 254. 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 tempo, and the overall evaluation are displayed on the menu screen. And if the user operates an arbitrary button, 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, it is possible to select: the swing evaluation device includes a rotation speed display screen that displays a feature related to a rotation speed of a waist, an angle display screen that displays a feature related to an angle of a waist, a movement amount display screen that displays a feature related to a movement amount of a waist, a swing tempo display screen that displays a feature related to a swing tempo, and a comprehensive evaluation display screen that displays a feature related to comprehensive evaluation.

The rotation speed display screen is a display screen including a numerical value representing the rotation speed (rotation angular speed) of the waist and the time from the posture of the upper stick to the maximum rotation speed of the waist, a graph representing the time change of the rotation speed of the waist, and the like.

The angle display screen is a display screen including numerical values representing the forward tilt angle, the rotation angle, the horizontal angle, the maximum value, the minimum value, the change width, and the like of each point in the swing.

The movement amount display screen is a display screen including an index indicating the magnitude (degree of movement) of the movement amount between each point in the swing in the up-down direction, the left-right direction, and the front-back direction. In the present embodiment, the index in the movement amount display screen represents, in a stepwise manner, the deviation of the swing of the measurement target person P from the statistical data based on the average of the swings of a given number or more of senior golfers (male and female professional golfers, etc.).

The swing tempo display screen is a display screen containing a numerical value or the like representing the elapsed time (required time between points) of each point in the swing.

The overall evaluation display screen is a display screen including a radar chart indicating the result of evaluating the swing of the measurement target person P by the score for each evaluation item, a numerical value representing the score, and the like.

Among these display screens, the rotation speed display screen displays a graph relating to the rotation speed of the waist.

Fig. 11 is a schematic diagram showing an example of the rotation speed display screen.

As shown in fig. 11, the rotation speed display screen includes a region R1 showing the maximum value of the waist rotation speed (rotation angular speed), a region R2 showing the time from the stance of the backswing to the maximum rotation speed of the waist, a region R3 representing a graph of the time change of the waist rotation speed, and a region R4 showing the potential for measuring the flying distance (potential flying distance) of the subject person P. The potential flight distance is calculated statistically (e.g., by averaging) the flight distances of the shots played by a plurality of players whose swing data is close to the measurement target person P.

As described above, in the case where the usage pattern of the waist is greatly different between the high-class level and the first-class level and the middle-class level of golf, and the time change (graph) of the waist rotation speed is observed, generally, the waveform of the waist rotation speed changes in the order of the mountain type, the single peak type, and the double peak type as the golf progresses.

The double-peak type is a type in which a waveform of a waist rotation speed is roughly clearly divided into a swing having a peak of a first half and a peak of a second half (2 large peaks) and a trough therebetween, and appears in advanced graders such as professional golfers. That is, the senior level stops the rotation of the waist once during the swing, and by this action, it becomes easy to increase the rotation speed of the waist.

The monomodal type is a type in which the waveform of the rotation speed of the waist is substantially a swing having a peak of 1 peak (large 1 peak). In the case of a monomodal swing, it means that the rotation speed is slow or the waist is not efficiently moved although the waist is rotated, and it is difficult to smoothly move the body weight as a result of the monomodal swing.

The mountain type is a continuous swing type in which the waveform of the rotational speed of the waist becomes a fragmentary peak. In the case of a mountain swing, the waist does not smoothly rotate from the top to the hitting, and in the case of a wrist-clasping or swinging, the swing is a mountain swing.

The person P to be measured who has confirmed the rotation speed display screen can visually determine which type of swing the person P is in accordance with.

In the present embodiment, when a predetermined operation (for example, an operation of displaying a recommended icon) is performed, the display control unit 255 displays a screen (hereinafter, referred to as "method presentation screen") that presents, as support information to the user, an explanation about the types of the swings and a method relating to improvement of the swing according to the types. In the method display screen, the display control unit 255 displays, for example, a swing improvement point and practice for improving a swing as support information.

Fig. 12 is a schematic diagram showing an example of display contents of the method presentation screen.

As shown in fig. 12, the method presentation screen displays: types of waveforms (bimodal, monomodal, mountain) that measure the rotation speed of the waist of the subject person P; the approximate evaluation results of the waist rotation speed (evaluation of the maximum rotation speed, the time from the posture of the upper rod to the maximum rotation speed of the waist, and o, x, and Δ associated with the appearance of 2 large peaks); and support information of each type. Further display of support information for lifting the swing is made for the bimodal swing, and in the example of fig. 12, a time to shorten the time from the posture of the backswing to the highest rotation speed of the waist and a suggested comment therefor are displayed. Further, support information indicating that the swing is a bimodal swing and a comment on a suggestion therefor are displayed for the monomodal swing. In addition, for the unimodal swing, an improved training for practicing the body is also shown in the example of fig. 12. Further, support information and advice information for a mountain swing to be a single-peak swing are displayed.

The contents of the method presentation screen may be stored in the processing device 2 or may be downloaded from a predetermined content server or the like as a link to an external device. In addition, the contents of the method presentation screen may be output by voice. This makes it easier for the measurement target person P who swings to grasp the display content.

Further, on the movement amount display screen, indices representing the magnitude (degree of movement) of the movement amounts in the up-down direction, the left-right direction, and the front-rear direction between the points in the swing are displayed.

Fig. 13 is a schematic diagram showing an example of the shift amount display screen.

As shown In fig. 13, In the movement amount display screen, the degrees of the horizontal movement amount, the vertical movement amount, and the front-back movement amount (deviation from the reference swing) between the respective points with respect to the swing of the measurement target person P are represented by the index In at 5 stages.

Fig. 14 is a schematic diagram showing a relationship between the index and the deviation.

In fig. 14, x1 to x12, y1 to y12, and z1 to z12 represent boundary values of the degree of movement.

As shown in fig. 14, in the case of displaying the movement amount display screen, in each of the items of the left and right, the front and back, and the up and down, the degree of deviation of the movement amounts of the waist at each point of the address ball to the upper stick, the upper stick to the front, and the front to the lower stick with respect to the statistical data is classified. Then, the index for identifying and displaying on the shift amount display screen is determined according to the range of the variation in classification (the range corresponding to the indexes a to E arranged from the negative side to the positive side). In fig. 14, the index C at the center corresponds to a range including "average value", and the range of the index C is set to a value represented by "deviation".

As the statistical data to be used as a reference in the case of obtaining the variation of the measurement target person P, an average value of the entire high ranking users of a predetermined number or more, and an average value of different models according to a left-handed player, a right-handed player, a male professional golfer, a female professional golfer, a type of club to be used, and the like can be used. In addition, the past own swing in which the measurement target person P determines to be a good swing can be used as a reference.

The recording control unit 256 stores the evaluation result data of the swing acquired by the swing evaluation unit 254 in the evaluation result storage unit 273 or the removable medium 231. When an operation to instruct storage of the evaluation result data is performed, the recording control unit 256 stores the evaluation result data.

[ actions ]

Next, the operation of the analysis system S will be described.

Fig. 15 is a flowchart illustrating the flow of the information detection process performed by the sensor assembly 1.

The information detection process is started together with the start of the sensor assembly 1.

In step S1, the communication control unit 151 is connected to the processing device 2 as a slave via BLE.

In step S2, the calibration execution unit 152 acquires the sensor information in the reference state in accordance with the instruction from the processing device 2, and executes the calibration with the acquisition result as the reference value.

In step S3, the calibration execution unit 152 notifies the processing device 2 of the completion of calibration by BLE.

In step S4, the detection processing unit 153 sequentially acquires various sensor information, and starts processing for associating the acquired sensor information with the acquired time and storing the sensor information in the sensor information storage unit 171.

In step S5, the detection processing unit 153 analyzes the waveform of the acquired sensor information, detects the timing of the address point in the golf swing, and transmits the address detection signal to the processing device 2 via BLE.

In step S6, the detection processing unit 153 analyzes the waveform of the acquired sensor information, detects the timing of the swing feed point in the golf swing, and transmits the swing feed detection signal to the processing device 2 via BLE.

In step S7, the detection processing unit 153 analyzes the waveform of the acquired sensor information, and detects the timing of each point of the backswing, downswing, and impact of the golf swing.

In step S8, the sensor information transmission control unit 154 converts the sensor information from the address to the feed bar into a preset sampling rate (for example, about 240 samples/second), and transmits the converted sensor information to the processing device 2.

After step S8, the process shifts to step S4.

After that, when an operation to end the information detection process is input, the information detection process ends.

Next, evaluation result display processing performed by the processing device 2 will be described.

Fig. 16 is a flowchart illustrating the flow of the evaluation result display process executed by the processing device 2.

The evaluation result display processing is started by an operation for instructing the start of the analysis result display processing via the input unit 218.

In step S11, the communication control unit 251 is connected to the sensor unit 1 through BLE as a host.

In step S12, the calibration management section 252 instructs the sensor assembly 1 to perform calibration.

In step S13, the calibration management part 252 receives a notification that the execution of calibration has been completed from the sensor assembly 1 through BLE.

In step S14, the display control unit 255 displays a guidance screen prompting the measurement target person P to address the ball.

In step S15, the communication control unit 251 receives the ball address detection signal from the sensor assembly 1 via BLE.

In step S16, the display control unit 255 displays a guidance screen for prompting the measurement target person to take a P swing.

In step S17, the communication control unit 251 receives a feed lever detection signal from the sensor unit 1 via BLE.

At step S18, the display control unit 255 displays a guidance screen indicating that the swing is being analyzed.

In step S19, the sensor information acquisition unit 253 acquires sensor information at a preset sampling rate from the sensor unit 1 by BLE.

In step S20, the display control unit 255 displays an evaluation result display screen representing 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. At this time, the display control unit 255 displays an evaluation result display screen (see fig. 10) corresponding to the button selected on the menu screen.

In step S21, the display control unit 255 determines whether or not an operation to instruct the display of the method presentation screen is performed.

When the operation to instruct the display of the method presentation screen is performed, the determination at step S21 is yes, and the process proceeds to step S22.

On the other hand, if the operation to instruct the display of the method presentation screen is not performed, the determination at step S21 is no, and the process proceeds to step S23.

In step S22, the display control unit 255 displays a method presentation screen.

In step S23, the recording control unit 256 determines whether or not an operation for instructing storage of evaluation result data has been performed.

If the operation for instructing the storage of the evaluation result data is not performed, the determination at step S23 is no, and the process proceeds to step S14.

On the other hand, when the operation for instructing the storage of the evaluation result data is performed, the determination at step S23 is yes, and the process proceeds to step S24.

In step S24, the recording control unit 256 stores the evaluation result data of the swing acquired by the swing evaluation unit 254 in the evaluation result storage unit 273 or the removable medium 231.

After step S24, the process shifts to step S14.

When an operation to end the evaluation result display processing is input thereafter, the evaluation result display processing ends.

By the above processing, the analysis system S can analyze the three-dimensional motion of the body of the measurement target person P based on the sensor information obtained by measuring the motion of the body of the measurement target person P, and display an evaluation result display screen representing the rotation speed of the waist, the angle of the waist, the amount of movement of the waist, the swing tempo, the comprehensive evaluation, and the like.

Among the evaluation result display screens, particularly the rotation speed display screen, a numerical value indicating the rotation speed of the waist (rotation angular speed), the time from the posture of the upper stick to the maximum rotation speed of the waist, a graph indicating the time change in the rotation speed of the waist, and the like are displayed.

Therefore, the type of the waist usage mode, which is important for the progress of golf, can be visually and easily displayed, and the progress of the swing of the measurement target person P can be accurately grasped.

Therefore, the quality of the movement of the measurement target person P can be more appropriately determined based on the sensor information (angular velocity, etc.) of the waist of the measurement target person P.

Further, among the evaluation result display screens, particularly the movement amount display screen, indexes representing the magnitudes (movement degrees) of the movement amounts in the vertical direction, the horizontal direction, and the front-rear direction between the points in the swing, and the like are displayed. The index in the movement amount display screen represents a deviation of the swing of the measurement target person P from the statistical data based on the average of the swings of a given number or more of senior level persons (male and female professional golfers, etc.).

Therefore, the difference between the swing of the measurement target person P and the swing of the senior level person can be visually and easily displayed in the items of the left, right, front, back, and up and down, and the degree of the deviation of the movement amount of the waist at each point of address to backswing, backswing to front, and front to backswing can be easily understood.

Therefore, the quality of the movement of the measurement target person P can be evaluated more appropriately based on the measurement value of the sensor attached to the waist of the measurement target person P.

As described above, according to the analysis system S of the present embodiment, it is possible to more appropriately evaluate whether the activity of the measurement target person P is good or not.

In addition, when evaluating whether the movement of the measurement target person P is good or not, the difference between the movement amount of the waist of the measurement target person P and a predetermined value such as an average value of the movement amounts of the waist of the high-level person, which is a reference statistical data, may be compared, and the movement of the measurement target person P may be evaluated as higher as the difference is smaller.

[ 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 representing the characteristics of the swing of the measurement target person P may be displayed.

For example, when the center of gravity is reversed or swung during the swing of the measurement target person P, an animation clearly showing the swing in which the center of gravity is reversed or swung may be displayed.

This makes it possible to clearly display the swing characteristics of the measurement target person P.

In the case of displaying the animation, the characteristics of the swing of the measurement target person P may be displayed in an exaggerated manner.

In addition, a numerical value representing the movement amount of the waist or the like may be displayed together with the animation.

[ modification 2]

In the above-described embodiment, the swing of the measurement target person P may be measured by using an imaging device such as a digital camera, a dynamic image of the swing may be captured, and the dynamic image of the swing may be displayed together with the evaluation result data in the evaluation result display process.

Thus, the numerical value, the graph, and the dynamic image of the swing representing the swing characteristics of the measurement target person P can be displayed together, and therefore, the evaluation result of the swing of the measurement target person P can be displayed in a more understandable form.

The analysis system S configured as described above includes the sensor unit 1 and the processing device 2. The sensor assembly 1 is fitted to the waist of a user. The processing device 2 includes a swing evaluation unit 254.

The swing evaluation unit 254 extracts a1 st peak waveform and a 2 nd peak waveform from the output result of the angular velocity measured by the sensor provided at the waist of the user.

The swing evaluation section 254 evaluates the motion of the user based on the extraction result.

This makes it possible to evaluate the movement of the user by focusing on the states of the 1 st peak waveform and the 2 nd peak waveform in the waveform of the angular velocity detected at the waist of the user.

Therefore, in the electronic device in which the movement of the user is detected by the sensor mounted on the waist, the user can be more appropriately determined whether the movement of the user is good or not.

The swing evaluation section 254 evaluates the motion of the user based on the shapes of the 1 st peak waveform and the 2 nd peak waveform.

Thus, whether the user's motion is good or not can be determined by reflecting the suitability of the specific shapes of the 1 st peak waveform and the 2 nd peak waveform.

The swing evaluation section 254 evaluates the motion of the user based on the relationship between the waveform shapes of the 1 st peak waveform and the 2 nd peak waveform.

This can reflect: whether the user's motion is good or not is determined by a condition other than whether the 1 st peak waveform and the 2 nd peak waveform are individually suitable or not, such as whether a suitable valley in which the angular velocity is substantially zero appears between the 1 st peak waveform and the 2 nd peak waveform.

The swing evaluation unit 254 determines whether or not the 1 st peak waveform and the 2 nd peak waveform are extracted, and evaluates the motion of the user based on the determination result.

This makes it possible to determine the waveform of the angular velocity appearing in the first-order level and the second-order level, and evaluate the motion of the user.

The processing device 2 includes a display control unit 255.

The display control unit 255 reports the evaluation result of the user's action to be evaluated.

This makes it possible to clearly inform the user of the evaluation result of the operation focusing on the states of the 1 st peak waveform and the 2 nd peak waveform.

The display control unit 255 reports advice information of the evaluation result based on the motion of the user under evaluation.

This can present advice information for promoting an operation focusing on the states of the 1 st peak waveform and the 2 nd peak waveform to the user.

The present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within a range that can achieve the object of the present invention are included in the present invention.

This makes it possible to more reliably detect the timing of a given characteristic point in the golf swing.

In addition, in the present specification, the steps describing the program recorded in the recording medium include not only the processing performed in time series in this order, but also processing performed in parallel or individually, instead of performing the processing in time series.
