JP6883357B2 - Sway detection device and sway detection program - Google Patents

Description

The present invention relates to a sway detection device, a sway detection system, and a sway detection program for detecting a sway of a user playing golf.

In a golf swing, it is generally preferable to keep the head position fixed during the swing. That is, it is preferable that the head does not move up, down, left, right, and back and forth during a series of movements such as address, backswing, top, downswing, and impact. This is because, in a golf swing, it is better not to move the head up / down / left / right during the swing to increase the meet rate and improve the accuracy of the shot.

However, some general golfers whose shots are not stable may move their heads during the swing, causing duffing, topping, and catching, resulting in a decrease in the meet rate. It seems that there are many cases. However, it is hard to notice that the head is moving during the swing, and it is very difficult to correct it if you have a habit of swaying with the swing.

In addition, it seems that some general golfers are weak users such as women who hit while swaying a little, but even so, if they sway too much, it will still lead to missed shots.

However, it is difficult for a swinger to notice for himself whether or not his head is moving during the swing, that is, whether or not he has swayed.

Therefore, usually, (1) swing while looking in the mirror, (2) have a third party such as a lesson pro check the swing, or (3) shoot with a video camera and see the shooting result. Check if you are swaying during the swing by any of the methods.

There is also a technique that supports golf swing practice by detecting a sway. As an example of such a technique, for example, the technique described in Patent Document 1 can be mentioned. The technique described in Patent Document 1 will be described (see, in particular, FIG. 2 of Patent Document 1).

In the technique described in Patent Document 1, a light emitting body 2 is attached to a user's head, and the position of a bright spot of the light emitting body 2 is monitored by a position measuring device provided inside the box 4. This makes it possible to determine whether or not the bright spot position at impact (that is, the position of the head at impact) deviates from the bright spot position at address (that is, the position of the head at address).

It is possible to determine whether or not swaying is performed by the above-mentioned three general methods, the technique described in Patent Document 1, and the like.

However, there have been various problems with these methods and techniques. It is a problem as described below, for example.

Regarding the above-mentioned method (1) of swinging while looking at a mirror, there are only a limited number of places where a mirror that reflects the whole body is installed and a golf swing can also be performed. Also, as a matter of fact, it is impossible to look in the mirror all the time during the swing while reproducing the usual form. Therefore, it remains unknown when the sway is occurring during the swing.

In addition, the method of having a third party such as (2) lesson pro check the swing is not always close to the lesson pro. Further, even if there is a lesson pro, it is difficult for the lesson pro to find a sway during the swing and to point out the occurrence of the sway before the end of the swing. Therefore, although it is possible to receive advice after the swing is completed, it is not possible to know the occurrence of the sway in real time during the swing.

Further, also in the above-mentioned method (3) of shooting with a video camera and viewing the shooting result, the shooting result is viewed after the swing is completed, and it is not possible to know the occurrence of the sway in real time during the swing.

Further, even in the technique described in Patent Document 1, only the sway at the time of impact can be determined, and the sway during the backswing and the downswing cannot be detected. Therefore, it is not known at what point in the series of swing movements the sway is occurring. Also, even if you are swaying during the swing, if the position of your head returns at the time of impact, you will not know that the sway is occurring during this swing.

As described above, no matter which method and technique was used, the occurrence of the sway could not be detected during the swing.

Therefore, an object of the present invention is to provide a sway detection device, a sway detection system, and a sway detection program capable of detecting that a sway has occurred even during a swing.

According to the first aspect of the present invention, the movement of the user's head while the user is swinging is measured, and the movement of the head meets a predetermined criterion at least during the measurement. A sway detection device is provided, which is characterized by producing a predetermined output at a time point.

The sway detection device provided from the first aspect will be described. A general technique including Reference 1 is a configuration in which a measurement is performed during a swing and a measurement result is output after the swing is completed. However, in the present invention, since the movement of the head is output "at least during the measurement" at a "time point" when the predetermined standard is satisfied, the swing is measured, that is, even during the swing. Output is done. Therefore, it is possible to output where the head has moved in the swing motion and where the head has moved. For example, it has an advantageous effect of knowing at what stage the head has moved from the address to the top position, from the top to the impact, and then the follow-through.

The movement of the user's head may be measured by, for example, installing a measuring unit such as a sensor outside the user and observing the user from outside the user. For example, the user may be observed by a camera, radar, or the like from the side surface, the back surface, the upper surface, the front surface, or the like of the user. In particular, it is advisable to install a measuring unit such as a sensor outside the user so as to directly observe the user's head. A better configuration is to install a measuring unit that measures the movement of the user's head. This is because the movement of the user's head can be directly measured. In particular, an output unit that produces a predetermined output may also be provided on the head.

Further, according to the second aspect of the present invention, it is preferable that the predetermined output can be detected by the user during the swing.

The sway detection device provided from the second aspect will be described. In the general technique including Reference 1, it is assumed that the measurement result is output after the swing is completed. Therefore, the viewpoint of telling the output to the user during the swing was lacking. According to the present invention, since the user during the swing can detect the output, the user can experience the problem of his / her swing. Therefore, for example, in a practice field or the like, even one person can correct and confirm the swing, which is an advantageous effect. As a configuration, it is preferable to detect with at least one or more of the five senses of the user who are not constrained by the swing.

When the sway detection device detects the sway, it is preferable that the sway detection device outputs some output to the sensory organs that are not restrained by the user during the swing. For example, when the sway detection device detects a sway, it is preferable to output some sound from the sway detection device. This is because the user's hearing is not constrained by the swing, so the user can detect the sound output. Similarly, for example, a sway detection device may be attached to a user's ear or the like so that the sway detection device vibrates when the sway detection device detects a sway. This is because the tactile sensation of the user's ear is not constrained by the swing, so that the user can detect the output due to vibration. Also, for example, it is good to combine sound output and vibration. This is because the user can detect the output more reliably.

Further, according to the third aspect of the present invention, the predetermined output may be performed each time the movement of the head satisfies a predetermined criterion.

The sway detection device provided from the third aspect will be described. The present invention detects a sway during a swing and outputs a predetermined output, but the sway does not always occur only once during the swing, and may occur a plurality of times. If the output is performed only once in such a case, the second and subsequent sways cannot be detected (recognized). However, in the present invention, as is clear from the description that the sway is performed "every time" satisfying a predetermined criterion, even if there are a plurality of sways, the output is performed each time each sway is generated, and the user Can be detected each time.

Further, according to the fourth aspect of the present invention, the predetermined reference is a reference relating to any one of the position, speed and acceleration related to the movement of the head, or a combination of two or more of them. It is good to feature that.

The sway detection device provided from the fourth aspect will be described. The present invention detects the occurrence of a sway from various viewpoints by using the velocity and the acceleration as a reference. For example, if only the displacement of the position is used as a reference and the velocity and acceleration are also used as a reference, the occurrence of the sway may be detected from various viewpoints. This makes it possible to detect a rapid sway at high speed or high acceleration, for example, although the position is not so deviated. This allows the user to detect that a sway has occurred that is not misaligned but should be corrected by practice.

Further, according to the fifth aspect of the present invention, it is preferable that the predetermined reference is determined and / or modified based on the measurement result for the past swing.

The sway detection device provided from the fifth aspect will be described. There are individual differences in the degree of sway during a swing (for example, blur width, speed, etc.). In the present invention, a predetermined reference is determined and / or modified based on the measurement history which is the measurement result of the past swing. At this time, by using the measurement history of the individual who uses the sway detection device, it is possible to determine an appropriate reference value according to the habit of the individual. This makes it easy to set a predetermined standard suitable for each individual.

Further, according to the sixth aspect of the present invention, the user accepts the selection of any of the past swings, and the predetermined criterion is determined or modified based on the measurement result of the selected past swings. It may be characterized by doing either or both.

The sway detection device provided from the sixth aspect will be described. As mentioned above, there are individual differences in the degree of sway. Therefore, it is necessary to determine and / or modify a predetermined standard according to each individual user, but it is preferable that there is some objective index in order for the user to set this appropriately. .. Therefore, in the present invention, a specific swing performed in the past is selected, and a reference is set based on the measurement result of the selected swing. The user selects, for example, a swing that seems to have the longest flight distance among past swings, a swing that flies straight, or a swing that the user has checked by a third party such as an instructor and is judged to be appropriate. That is, based on the result actually given to the ball and the objective index for the user such as the subjectivity of a third party, the swing considered to be ideal among the own swings in the past is selected. Then, a predetermined criterion is set based on the selected swing. For example, by using the measured value of the selected swing as a predetermined reference, a sway is detected when the movement deviates from the selected swing motion. This makes it possible to practice to reproduce this selected ideal swing. Further, for example, instead of the swing considered to be ideal, or along with the swing considered to be ideal, a swing considered to have a sway may be selected. For example, a setting for determining that a predetermined criterion is satisfied between the amount of movement of the head of a swing selected as an ideal swing and the amount of movement of the head of a swing considered to have a sway. May be.

Further, according to the seventh aspect of the present invention, the predetermined condition may be determined and / or modified based on the input received from the user.

The sway detection device provided from the seventh aspect will be described. It is possible to let the user set an arbitrary standard. In addition, the standard once set can be modified. This makes it possible to use it as a reference for detecting a sway according to, for example, a user's preference.

Further, according to the eighth aspect of the present invention, the measured value regarding the magnitude and direction of the moving distance of the head, the measured value regarding the magnitude and direction of the moving speed of the head, and the magnitude of the moving acceleration of the head. It may be characterized in that it is determined whether or not the predetermined criteria are satisfied based on any one or a combination of two or more of the measured values relating to the sword and the direction.

The sway detection device provided from the eighth aspect will be described. In the present invention, it is preferable to use various measured values to make a judgment regarding a predetermined condition. For example, even if the amount of sway in the vertical direction is smaller than the amount of sway in the horizontal direction, it may be determined that the predetermined criterion is satisfied.
As a result, even if there is a sway that should be detected from the viewpoint of swing practice and cannot be detected based on a certain measured value, it can be detected by using another measured value.

Further, according to the ninth aspect of the present invention, it is preferable to make the predetermined reference different depending on the direction in the three-dimensional space.

The sway detection device provided from the ninth aspect will be described. For example, when the determination is made based on the size of the moving distance, the sway in the left-right direction may be allowed to some extent, but the sway in the up-down direction may be strictly determined. For example, there is a methodology that it is better not to sway at all, but in this way, for example, it is possible to correspond to a methodology that allows a sway to the right to some extent. In this case, it is advisable to make the reference values different in the right direction and the left direction.

Further, according to the tenth aspect of the present invention, it is preferable to make the predetermined reference different from a certain time point during the swing and another time point other than the certain time point.

The sway detection device provided according to the tenth aspect can have different predetermined criteria during a series of swings. For example, it is judged that a relatively large sway is unlikely to occur during the backswing at the beginning of the swing, so the standard is strict, while a relatively large sway is likely to occur during the downswing, so the standard is loosened. It is good to have a configuration.

Further, according to the eleventh aspect of the present invention, the user accepts and accepts input for at least one of the club type information used for the swing, the user's gender information, and the user's physique information. It is advisable to make the predetermined criteria different based on the information obtained.

The sway detection device provided from the eleventh aspect will be described. The size of the sway tends to be different if the club used for the swing, the gender of the user, the physique of the user, etc. are different. Therefore, it is possible to input information such as the club used for these swings, the gender of the user, and the physique of the user, and set a predetermined standard corresponding to the tendency.

Further, according to the twelfth aspect of the present invention, it is preferable to set a plurality of the criteria and make the contents of the output different according to the satisfied criteria.

The sway detection device provided from the eleventh aspect will be described. By making the output different according to the standard, the user who detects the output can know which standard the sway was detected from. For example, it is possible to grasp whether the vehicle has moved to the right, to the left, or at a speed higher than a predetermined speed.

Further, according to the thirteenth aspect of the present invention, the recording means for recording the movement of the user's head measured during the swing in association with the measurement time and the movement at the time of measurement, and the recording means. It is preferable to provide a display means for displaying the movement of the head based on the recorded contents of the above so that the movement of the head can be grasped along the time series during the swing.

The sway detection device provided from the thirteenth aspect will be described. According to the present invention, it is possible to grasp the movement during the swing over time in chronological order, instead of displaying only a certain time point during the swing. This allows the user to understand at what stage during the swing and how the sway is occurring.

Further, according to the fourteenth aspect of the present invention, it is preferable to start the measurement when the predetermined operation of the user is detected.

The sway detection device provided from the 14th aspect will be described. By doing so, it is possible to prevent a situation in which measurement is performed when it is not necessary.

Further, according to the fifteenth aspect of the present invention, the impact is detected based on either or both of the moving speed of the club used by the user for the swing and the moving speed of the ball launched by the club, and the impact is determined. It is preferable to end the measurement based on the detection.

The sway detection device provided from the fifteenth aspect will be described. It is possible to automatically end the measurement based on the detection of impact.

Further, according to the 16th aspect of the present invention, the microwave emitted from the Doppler sensor is reflected by either or both of the club and the ball, and the moving speed of the club and the ball are based on the frequency of the reflected wave. It is advisable to measure either or both of the moving speeds of.

Further, according to the seventeenth aspect of the present invention, it is preferable that the measurement is a measurement using an acceleration sensor.

Further, according to the eighteenth aspect of the present invention, the measurement may be configured to perform the measurement using the acceleration sensor and the gyro sensor.

Further, according to the nineteenth aspect of the present invention, the sway detection program characterized in that the computer functions as a sway detection device provided by any one of the first to eighteenth aspects of the present invention. Provided.

The sway detection program provided from the 19th viewpoint will be described. The program can also realize the sway detection device provided by any of the first to eighteenth aspects of the present invention described above.

According to the present invention, it is possible for the user to detect that a sway has occurred during a swing.

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the sway detection device 100 of the present embodiment includes a sound output unit 101, an operation reception unit 102, an external connection unit 103, a vibration unit 104, a control unit 105, a sensor unit 106, a detection reference storage unit 107, and a detection reference storage unit 107. The measurement history storage unit 108 is included.

The sway detection device 100 is a device that monitors the movement of the user by the sensor unit 106, detects that the user has swayed based on the monitoring result, and notifies the user that the sway has been detected. In the following description, the sway detection device 100 is realized in the shape of earphones or headphones as an example of the present embodiment. Then, the sway detection device 100 is attached to the ear of the user who performs the golf swing and is used.

The sound output unit 101 outputs a sound when a sway is generated based on the control of the control unit 105. The user can recognize that the sway has occurred by listening to the sound output from the sound output unit 101. Hereinafter, the sound output from the sound output unit 101 will be referred to as a "sway detection sound" for convenience of explanation. The sound output unit 101 is realized by a mechanism for sound output provided in a general earphone.

The operation receiving unit 102 is a part that receives an operation from the user. The operation reception unit 102 accepts operations such as turning on and off the power and adjusting the volume.

The external connection unit 103 is an interface for the sway detection device 100 to connect to an external device. The sway detection device 100 is driven by a battery (not shown). Then, this battery is supplied with power via the external connection unit 103 and is charged. The external connection unit 103 is also used for transmitting and receiving data to and from an external device.

The vibrating unit 104 vibrates when a sway is generated based on the control of the control unit 105. The user can recognize that the sway has occurred by feeling the vibration caused by the vibrating unit 104. Hereinafter, the vibration generated by the vibrating unit 104 will be referred to as "sway detection vibration" for convenience of explanation. The vibrating unit 104 is realized by, for example, a small motor.

The control unit 105 is a control unit that controls the entire sway detection device 100, and when the control unit 105 controls other functional blocks, various processes described below are realized. Specifically, the control unit 105 includes an arithmetic processing unit, and the arithmetic processing unit is stored in a storage unit included in the control unit 105 or another storage unit. The sway detection device 100 is realized by performing processing and controlling each hardware based on the calculation result.

The sensor unit 106 measures the movement of the user's head during the swing and outputs the measurement result to the control unit 105. The sensor unit 106 is realized by a sensor such as a gyroscope (also called a gyro sensor) that measures the angle of the user's head and each speed, an acceleration sensor that measures the acceleration of the user's head, or a combination of these sensors. To.

The detection standard storage unit 107 stores a "detection standard", which is a predetermined standard for the control unit 105 to determine that a user's sway has occurred. Then, when the measurement result of the sensor unit 106 satisfies this detection criterion, the control unit 105 determines that the user's sway has occurred. The detection standard can be arbitrarily set, and can be, for example, a standard based on the position, speed, and acceleration of the movement of the user's head.

The measurement history storage unit 108 stores the measurement result by the sensor unit 106 as a “measurement history”.

A specific example of the measurement target by the sensor unit 106, a specific example of the detection standard, how to use the measurement history, and the like will be described later.

Subsequently, the operation of the present embodiment will be described in detail with reference to the flowchart of FIG.

First, the operation reception unit 102 receives an instruction from the user to turn on the power or start measurement. As a result, each part of the sway detection device 100 is activated, and the sensor part 106 starts measuring the movement of the user's head (step S11).

When the measurement is started, the sensor unit 106 outputs the measurement result obtained by measuring the movement of the user's head to the control unit 105. Then, the control unit 105 inputs the measurement result output by the sensor unit 106, stores it in the RAM provided in the control unit 105, and compares the detection standard stored in the detection reference storage unit 107 with the input measurement result. Thereby, it is determined whether or not the measurement result satisfies the detection criterion (step S12).

Here, if the measurement result satisfies the detection criterion (Yes in step S12), the process proceeds to step S13.

In step S13, the control unit 105 instructs the sound output unit 101 to output the sway detection sound. Similarly, the control unit 105 instructs the vibrating unit 104 to generate the sway detection vibration.

The sound output unit 101 outputs a sway detection sound to the user in response to an instruction. Further, the vibrating unit 104 also outputs a sway detection signal in response to the instruction (step S13). The user detects these sway detection sounds and sway detection vibrations by the five senses that are not constrained by the swing, the auditory sense and the tactile sense around the ear. This allows the user to detect that the movement of his or her head has swayed.

On the other hand, if the measurement result does not satisfy the detection criterion (No in step S12), the process proceeds to step S14. Further, even after the end of step S13, the process proceeds to step S14.

In step S14, it is determined whether or not a predetermined time has elapsed from the start of the measurement in step S11. Here, the length of the predetermined time can be arbitrarily determined, but for example, it is set to be a sufficient length from the start of one swing to the end of this swing. For example, it may be the general time required to require one swing, or the time required to practice one series of swings. In addition, the user may be able to select or specify a predetermined time. Then, if the predetermined time has not elapsed (No in step S14), the determination in step S12 is performed again while continuing the measurement.

On the other hand, if the predetermined time has elapsed (Yes in step S14), the process proceeds to step S15.

In step S15, the history of the measurement result stored in the RAM provided in the control unit 105 in step S12 is stored in the measurement history storage unit 108 as the measurement history. Specifically, the measurement content and the measurement date and time of the user's swing this time are stored in association with each other. As a result, the operation of the present embodiment is completed.

Subsequently, the effect of the present embodiment will be described.

In the present embodiment described above, the output is performed to the user based on the detection of the sway, and the user detects the output by the five senses that are not constrained by the swing, the auditory sense and the tactile sense around the ear. This has the effect that the user can detect that the movement of the user's own head has swayed.

Further, since the processes of steps S12 and S13 are performed regardless of whether or not the swing is in progress, the user can detect the occurrence of the sway in real time even during the swing.

Further, since the processing of step S12 and step S13 is performed as quickly as possible, the user can immediately detect the occurrence of the sway when the sway during the swing occurs. Therefore, it is possible to know at what stage of one's swing the sway has occurred. For example, it has the effect of being able to know at which stage the sway has occurred, from the address to the top position, from the top to the impact, and then the follow-through. For example, the input of the measurement result from the sensor unit 106 in step S12 and the comparison with the detection reference may be repeatedly executed every several tens of milliseconds at the latest.

Subsequently, as a modification of the above-described embodiment, a case where the higher-level device 200, which is a higher-level device that can be connected to the above-mentioned sway detection device 100, and the above-mentioned sway detection device 100 are connected and used will be described.

First, the functional blocks included in the host device 200 will be described with reference to FIG.

As shown in FIG. 3, the host device 200 includes a display unit 201, an external connection unit 202, an operation reception unit 203, and a control unit 204.

The display unit 201 is a portion that displays information to the user, and is realized by, for example, an LCD (Liquid Crystal Display), an organic EL (Organic Electro-Luminescence) display, or the like. Examples of the information displayed on the display unit 201 include a user interface that the user refers to when performing an operation, and information that allows the user to grasp the measurement history.

The external connection unit 202 is an interface for connecting the sway detection device 100 and the host device 200. The sway detection device 100 and the host device 200 transmit and receive data via the external connection unit 103 and the external connection unit 202.

The operation receiving unit 203 is a part that receives an operation from the user.

The control unit 204 is a control unit that controls the entire host device 200, and when the control unit 204 controls other functional blocks, various processes described below are realized. Specifically, the control unit 204 includes an arithmetic processing unit, and the arithmetic processing unit performs arithmetic processing based on a program specific to the present embodiment stored in the control unit 204 or another storage unit. The host device 200 is realized by controlling each hardware based on the calculation result.

Next, an example of the content displayed on the display unit 201 will be described with reference to FIG.

The measurement history storage unit 108 of the sway detection device 100 stores the position, velocity, acceleration, and the like of the head at each time point during the swing in the past swing as the measurement history in chronological order. The host device 200 acquires this measurement history from the sway detection device 100 via the external connection unit 103 and the external connection unit 202. Then, the movement of the user's head during the swing is displayed based on the measurement history.

As shown in FIG. 4, an image diagram showing a state in which the user is viewed from above is displayed on the left side of the display unit 201. Then, the movement of the user's head during the swing in each direction is displayed by an arrow on this image diagram representing the user. In addition, the length of the arrow corresponds to the magnitude of the movement of the user's head. The length of the arrow in each direction may be determined, for example, by searching for a value indicating the maximum amount of movement from the reference position in the measurement history. The reference position may be the position when the club is held, for example, the position where there has been no movement for a certain period of time in the history (the position where the club is contained in a predetermined small amount).

In this example, when the top of the head of the user is in the center and the front of the user is on the upper side, it can be seen that the head of the user moves the most in the direction from the center to the right side. In addition, it can be seen that the user's head did not move in the direction of diagonally forward right or diagonally backward right. Further, as shown in FIG. 4, an image diagram showing a state in which the user is viewed from the side is displayed on the right side of the display unit 201. Then, as in the figure on the left side of FIG. 4, the movement of the user's head is represented by an arrow on the image diagram showing the user. In this example, when the user's head is used as a reference, the zenith direction is the upper side, and the zenith direction is the lower side, it can be seen that the user's head moves more upward than the lower side. In addition, the length of the arrow corresponds to the magnitude of the movement of the user's head.

By referring to such an image diagram displayed on the display unit 201, the user can visually grasp how his / her head is swaying. For example, the arrow may be thickened in the direction of movement at a relatively high speed during the swing, and the arrow may be thinned in the direction of movement at a relatively low speed. It is also good to change the color of the arrow according to the speed, for example.

Subsequently, another example of the display information in the display unit 201 will be described with reference to FIG.

As shown in FIG. 5, similarly to FIG. 4, an image diagram showing a state in which the user is viewed from above and an image diagram showing a state in which the user is viewed from the side are displayed. However, FIG. 5 differs from FIG. 4 in that the locus of movement along the time series of the swing is shown as a display showing the movement of the user's head. In FIG. 5, the movement from the position of the head at the start of the swing to the position of the head at the end of the swing is represented by a single arrow. Taking the movement seen from above as an example, it can be seen that the head once moved to the right side and then to the left side with the swing. It can also be seen that the user's head moved slightly forward with the swing. The point that the color and thickness of the arrow may be changed is the same as the example shown in FIG. Further, the display of FIGS. 4 and 5 may be switched by a switching button or the like. Alternatively, the display of FIG. 4 and the display of FIG. 5 may be performed at the same time, such as displaying FIG. 4 on the upper side of the screen and displaying FIG. 5 on the lower side of the screen.

The measurement history stored in the measurement history storage unit 108 may be stored only for the most recent one swing, but it is preferable to store the measurement history for a plurality of swings. In this case, it is preferable that the operation reception unit 203 accepts the user's operation and switches the swing to be displayed according to this operation.

It is also good to display the movements of a plurality of swings on the screen at the same time. By doing so, for example, the movement of the head during a certain favorable swing in the past (for example, a swing with a long flight distance or a swing in which the ball flies straight) is compared with the movement of the head of this swing. It becomes possible. By referring to this screen, the user can grasp how to move to make a swing similar to a certain preferable swing in the past. It should be noted that the swing used for determining the detection criterion, which will be described later, may be specified from the displayed multiple swing movements.

By connecting the host device 200 provided with the display unit 201 to the sway detection device 100 in this way, it is possible to visually recognize the movement of the head during the swing.

Next, a specific example of the measured value by the sensor unit 106 and a specific example of the detection standard will be described.

The objects to be measured by the sensor unit 106 include, for example, a measured value relating to the magnitude and direction of the moving distance of the user's head, a measured value relating to the magnitude and direction of the moving speed of the user's head, and a moving acceleration of the user's head. Examples of measured values relating to the size and direction of the above.

Further, as a specific example of the detection standard, setting a threshold value for the moving distance of the movement of the user's head can be mentioned. Another example is to set a threshold value for the moving speed of the user's head. Further, setting a threshold value for the acceleration of the user's head can be mentioned.

Then, in step S12, when the measurement result of the sensor unit 106 exceeds these threshold values, it is determined that the reference is satisfied. When the measurement result of the sensor unit 106 continues to exceed these threshold values for a predetermined time, it may be determined that the reference is satisfied. The predetermined time may be, for example, a time at which it can be generally considered that a sway has occurred. For example, it may be a case where it lasts for 200 ms or more. Further, it may be determined that the criterion is satisfied when any one threshold value is exceeded or when any one threshold value is continuously exceeded, but when a plurality of threshold values are exceeded or when a plurality of threshold values are continuously exceeded. It is also good to judge that the criteria are met.

It is also good to judge that the standard is satisfied when the integrated value of the measured values for a predetermined time exceeds the threshold value instead of the measured values themselves.

Furthermore, it is also good to consider the direction. In this case, for example, when the measurement result itself of the sensor unit 106 in a certain direction or the integrated value of the measurement result exceeds the threshold value, it may be determined that the reference is satisfied.

As an example, in general, the sway in the direction in which the ball is thrown tends to be small, and the sway in the opposite direction tends to be large. For example, if the ball is to be thrown in the direction of the user's left foot, the user's head sways greatly in the direction of the right foot. Therefore, it is also good to set the threshold value in the right foot direction of the user to be larger than the threshold value in the left foot direction. Further, for example, if the sway tends to be larger in the middle of the swing than at the start of the swing, the threshold value at the time of swing disclosure is set small, and the threshold value is set large after a predetermined time has passed from the start of the swing. It is good to do so.

Next, a guideline for setting a detection standard for detecting a sway will be specifically described with reference to FIG. FIG. 6 is a diagram showing a state at the time of impact of a golf swing, and shows a golf club 301 and a golf ball 302.

Here, the diameter of a general golf ball is about 42.67 mm. Therefore, when hitting a golf ball 302 with a golf club 301 such as an iron, it is necessary to insert the leading edge of the golf club 301 such as an iron within about 20 mm from the ground with the hole placed on the ground. Then, the vertical movement of the golf club 301 within the range of 20 mm causes the golf club 301 to top or duff, making it impossible to properly fly the golf ball 302. Therefore, it is advisable to set the detection standard with an accuracy that can detect a sway that leads to vertical movement within at least this 20 mm range. For example, it is advisable to set the detection standard with an accuracy that can detect a sway that leads to a vertical movement of about 5 mm.

Next, the operation at the time of determining and correcting the detection standard stored in the detection standard storage unit 107 will be described.

The detection standard may be set in advance. However, there are individual differences in the size of the sway. Moreover, it is considered that the sway becomes smaller as the swing improves even for the same person. Therefore, it is preferable that the detection standard can be determined and modified by the user.

For example, it is preferable that the operation receiving unit 203 accepts the user's operation so that the detection standard can be modified according to the operation. As a specific example, it is conceivable to accept an operation from the user when the sway is frequently detected and correct the threshold value, which is the detection standard, to a large value. Further, when the user improves and the sway is hardly detected, it is conceivable to accept the operation from the user and correct the threshold value which is the detection standard to a small value.

In addition, for example, it is also possible to automatically correct the threshold value, which is a detection standard, based on the detection status of the sway, etc., instead of using the user's operation reception as an opportunity. For example, when the number of swings in which a sway occurs reaches a predetermined number, the threshold value is corrected to a large value, and when the number of swings in which a sway does not occur reaches a predetermined number of times, the threshold value is corrected to a small value. It is good to set it to.

It is also good to receive various information related to the swing from the user and determine the detection standard based on this information. Examples of various information include club type information used by the user for swing, user gender information, and user physique information. More specifically, for example, when comparing the swing when using an iron and the swing when using a driver, it is considered that the swing when using a driver tends to have a larger sway. Therefore, for example, when the user accepts that the swing is performed using the driver, the threshold value may be set to a larger value than when the user accepts the swing using the iron.

Further, for example, it is considered that a person having a large physique tends to have a larger sway than a person having a small physique, so it is also good to determine the threshold value accordingly. In addition, since women are generally less powerful than men, it is considered that women tend to have a larger sway than men. Therefore, it is also good to accept the input to select the gender so that the threshold value for women is larger than that for men. These settings may be configured such that the setting screen is displayed on the display unit 201 of the host device 200, and the setting contents are determined and corrected according to the input instruction from the operation reception unit 203. In this case, the setting contents may be transferred to the sway detection device 100 via the external connection unit 202 and the external connection unit 103. The sway detection device 100 may be configured to perform processing according to the setting contents transferred from the host device 200 in this way.

Next, the detection of the start and end of the swing of the user will be described.

If the user constantly measures without detecting the start and end of the swing, if the user walks around with the sway detection device 100 attached, the sway detection sound sounds when the user is not swinging. It is conceivable that it will end up. Therefore, in the above-described embodiment, the measurement is started when the user's operation is accepted in step S11. Further, the measurement was completed when the predetermined time elapsed in step S14. However, it is even better if this can be transformed to automatically detect the start of the swing and start the measurement. It is even better if the end of the swing can be automatically detected and the measurement can be completed.

Here, in a general golf swing, it is considered that the user's head should not move at least until the moment of impact of the club face and the ball after entering the address. Therefore, it is desirable to monitor the movement of the user's head at least from the time the address is entered to the moment of impact. Therefore, in the following description, the entry into the address and the moment of impact are detected. Then, when it is detected that the address has been entered, the measurement by the sway detection device 100 is started. Further, since it is considered that no further measurement of the swing is necessary after the moment of impact is detected, the sway detection device 100 ends the measurement of the swing and stops the motion monitoring of the head. There is also an idea that it is better not to move your head for a while after entering follow-through as a swing methodology. If this idea is followed, it is advisable to monitor the movement of the head for a while after entering the follow-through by continuing the measurement for a predetermined length of time after detecting the moment of impact. ..

Next, three specific examples of the configuration for detecting the moment of entering the address and the moment of impact will be described.

First, the first configuration will be described with reference to FIG. 7. As shown in FIG. 7, in this configuration, the host device 200 further includes an image acquisition unit 205, an image recognition unit 206, and a notification unit 207 in addition to the configuration of FIG. The video acquisition unit 205 has a function of shooting a moving image. Further, the image recognition unit 206 has a function of performing image recognition. The notification unit 207 includes a function of notifying the user.

Then, the image acquisition unit 205 captures an image of the user swinging, and the image recognition unit 206 determines that the image has entered the address and the moment of impact.

Further, when the image recognition unit 206 recognizes that the address has been entered, the control unit 204 of the host device 200 indicates that the swing has been started for the sway detection device 100 via the external connection unit 202 and the external connection unit 103. Send a signal. Upon receiving the signal indicating that the swing has started, the control unit 105 activates the sensor unit 106 and starts monitoring the movement of the user's head (corresponding to step S11). In this respect, it is necessary to prevent the image recognition unit 206 of the host device 200 from executing the swing of the user before the address recognition, that is, before the start of measurement. Therefore, for example, it is preferable to notify the user that the address has been recognized by the notification unit 207 of the host device 200. For example, the notification unit 207 is realized by an LED (Light Emitting Diode) or the like. Then, at the same time that the image recognition unit 206 of the host device 200 finishes recognizing the address, the notification unit 207 is turned on. The user starts takeback after seeing the lighting of the notification unit 207. As a result, it is possible to prevent a situation in which a swing is performed before the start of measurement. Further, when the image recognition unit 206 of the host device 200 finishes recognizing the address, the sound or vibration unit 101 or the vibration unit 104 of the sway detection device 100 outputs the sound or vibration to recognize that the address has been entered. It is also good to notify the user that this has been done. Then, the user may start takeback after receiving the notification.

Further, when the image recognition unit 206 of the higher-level device 200 can recognize the moment of impact, the control unit 204 of the higher-level device 200 finishes the impact on the sway detection device 100 via the external connection unit 202 and the external connection unit 103. Send a signal to that effect. The control unit 105 that has received the signal indicating that the impact has ended ends the measurement by the sensor unit 106 (corresponding to Yes in step S14). This makes it possible to measure a series of movements during the swing.

Next, the second configuration will be described with reference to FIG. As shown in FIG. 8, in this configuration, the host device 200 further includes a motion sensor 208 in addition to the configuration of FIG. The motion sensor 208 is a sensor for detecting the location of the user by using infrared rays or ultrasonic waves.

When using this configuration, the host device 200 is installed in front of the place where the user swings. Then, when the motion sensor 208 detects that the user is in front of the higher-level device 200, the control unit 204 of the higher-level device 200 connects the sway detection device 100 to the sway detection device 100 via the external connection unit 202 and the external connection unit 103. A signal indicating that the user is in front of the host device 200 is sent.

When the sway detection device 100 receives a signal indicating that the user is in front of the higher-level device 200, the sway detection device 100 enters the play mode. Then, when a tilted state (for example, holding the same posture for 2 seconds) that seems to be the address posture of the user is detected during this play mode, it is recognized that the user has entered the address, and monitoring of the movement of the head is started (step S11). ..

Then, when the motion sensor 208 detects that the user has disappeared from the front of the higher-level device 200, the control unit 204 of the higher-level device 200 connects the external connection unit 202 and the external connection unit 103 to the sway detection device 100. A signal indicating that the user in front of the host device 200 has disappeared is sent through the device. When the sway detection device 100 receives a signal indicating that the user has disappeared from the front of the host device 200, the play mode is turned off and the measurement is terminated (corresponding to Yes in step S14).

Further, as a third configuration, a configuration in which a device for measuring swings as described in Patent Documents 2 and 3 and a host device 200 are combined, and a function for measuring swings in the host device 200 are further added. A configuration of adding is conceivable.

Here, in the devices described in these cited documents, the microwave emitted from the Doppler sensor is reflected by either or both of the club and the ball, and the measurement is performed by analyzing the frequency of the reflected wave.

Specifically, the ball speed of the ball launched by the club head and the head speed of the club head are measured.

Then, by using such a measuring device, it can be determined that the address is entered at the moment when the measured head speed becomes almost zero. Further, the moment of impact can be detected from the change of either one or both of the measured head speed and the ball speed. Therefore, by starting and ending the measurement of the sway detection device 100 based on these determinations and detections, it is possible to measure a series of movements during the swing.

Further, if the equipment described in the cited document is used, the estimated flight distance can be derived from either the measured head speed or the ball speed. Therefore, it is preferable to display the head speed, the ball speed, and the estimated flight distance. By referring to this information, the user can compare, for example, the movement of the head when the estimated flight distance is long and the movement of the head when the estimated flight distance is short.

Further, as another method, it is also good to determine the end of the swing based on the change of the measured value by the sensor unit 106 instead of modifying the configuration. For example, since it is considered that the movement of the head stops once at the end of the follow-through, it may be determined that the swing has ended when the speed becomes significantly slower than before during the speed measurement.

It should be noted that, as is common when detecting the address posture by any method, if it takes too much time to detect the address posture, it becomes difficult for the user to take back the timing or the body becomes stiff. , It is possible that a smooth swing will not be possible. Therefore, it is preferable to detect the address posture by a method that does not take as much time as possible.

Although the embodiments described above are preferred embodiments of the present invention, the scope of the present invention is not limited to the above-described embodiments, and various modifications are made without departing from the gist of the present invention. It is possible to carry out in.

For example, in the above description, the sway detection device 100 is realized by an earphone-shaped device. However, this is only one realization example, and other shapes may be adopted. In particular, the shape should be such that it can be worn on the user's head. For example, the shape may be a headphone shape, a glasses type, a hair clip type, a headband type, a headband type, a hat type, an earring type, or the like.

Further, each functional block of the sway detection device 100 may be realized by a plurality of devices instead of being realized by a single device. For example, it is preferable to provide the sensor unit 106 in the earphone-shaped first device and transmit the measurement result to another second device. Then, the control unit 105 and the detection reference storage unit 107 are provided in the second device, the second device detects the sway, and the sound output unit provided in the first device is provided based on the instruction of the second device. It is preferable to make 101 or the vibrating unit 104 output a sway detection sound or a sway detection vibration. This also makes it possible to reduce the size of the first device.

Further, in the above description, both the sway detection sound and the sway detection vibration are output, but it is also possible to output either one. As a result, it is sufficient to provide only one of the sound output unit 101 and the vibration unit 104. Further, if the output is such that the user works on the five senses that are not restrained during the swing, it is also good to output the sway detection by a method other than sound or vibration.

Also, it is advisable to use multiple types of notification methods properly. For example, multiple sway detection sounds are prepared by different pitches and lengths of sounds. Then, different outputs are associated with each of the plurality of detection criteria. By doing so, it becomes possible for the user to grasp which detection standard is satisfied when the sway detection sound is heard. For example, by making the sway detection sound when a sway in the left-right direction occurs different from the sway detection sound when a sway in the vertical direction occurs, the user can sway his / her own head in the vertical direction. It is possible to grasp whether the sound is swayed in the left-right direction.

Further, data transmission / reception via the external connection unit 103 and the external connection unit 302 may be performed by wired communication via a cable based on a standard such as USB (Universal Serial Bus), for example. Further, it is particularly preferable to realize the external connection unit 103 and the external connection unit 302 with a module for wireless communication so that data can be transmitted and received by wireless communication. In this way, the degree of freedom of the user's body movement is increased and it is less likely to interfere with the swing. In addition, the degree of freedom in installing the host device 200 can be increased.

Further, as shown in FIG. 2, in the present embodiment, if it is before the elapse of a predetermined time or before the detection of the moment of impact, the output is performed every time the detection standard is satisfied. That is, it is assumed that there may be a plurality of outputs during one swing, but if the outputs occur frequently, it may be difficult to recognize at which stage during the swing the sway occurred. Therefore, it is also possible to set the number of outputs in one swing to a predetermined number or less, for example, only once or twice. In such a configuration, after step S13, a step for confirming whether the number of outputs is less than or equal to the predetermined number of times is further provided, and if the number of times of output exceeds the predetermined number of times, the determination in step S14 is not performed. The process may proceed to step S15. This improves the certainty of detection by the user of the output.

Further, although the measurement history is used in the above-described embodiment, it is also possible to use a device that performs sway detection without using the measurement history. In such a configuration, the measurement history storage unit 108 can be omitted. Further, the process of step S15 is also unnecessary. Further, the measurement history storage unit 108 may be provided in the host device 300.

In the above description, the present embodiment is exclusively used for detecting the sway during a golf swing, but the present embodiment may be used for other purposes. For example, the present embodiment can be used for sports other than golf, competitions such as billiards, and the like for practicing a situation in which a predetermined movement is performed without moving the head.

The above-mentioned sway detection device can be realized by hardware, software, or a combination thereof. Further, the communication method performed by the above-mentioned sway detection device can also be realized by hardware, software, or a combination thereof. Here, what is realized by software means that it is realized by a computer reading and executing a program. For example, some processing may be executed by an external device such as a server connected via a communication line.

Programs can be stored and supplied to a computer using various types of non-transitory computer readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-temporary computer-readable media include magnetic recording media (eg, flexible disks, magnetic tapes, hard disk drives), optomagnetic recording media (eg, optomagnetic disks), CD-ROMs (Read Only Memory), CD- Includes R, CD-R / W, semiconductor memory (eg, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory). Also, programs are of various types of temporary. The computer may be supplied by a transparent computer readable medium. Examples of temporary computer readable media include electrical signals, optical signals, and electromagnetic waves. Temporary computer readable media are electric wires. The program can be supplied to the computer via a wired communication path such as an optical fiber or a wireless communication path.

Further, although the above-described embodiment is a preferred embodiment of the present invention, the scope of the present invention is not limited to the above-described embodiment, and various modifications have been made without departing from the gist of the present invention. It can be implemented in the form.
