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 who plays golf.

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

  However, some general golfers whose shots are not stable will cause their head to move during the swing, causing duffing, topping, and hooking, resulting in a lower meat rate. It seems that there are many cases. However, the fact that the head is moving during the swing is something that is difficult to notice on its own, and it is very difficult to correct if there is a habit that causes you to sway on the swing.

  In addition, it seems that there are some general golfers who hit a little while swaying with a powerless user such as a woman, but if they sway too much, they will still lead to a miss shot.

  However, it is difficult for the person who is swinging to notice for himself whether or not the head is moving during the swing, that is, whether or not the sway has been made.

  So, usually (1) swing while looking in the mirror, (2) have a third party such as a lesson professional check the swing, or (3) shoot with a video camera and see the shooting results, It is confirmed whether it is not swaying during the swing by any method.

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

  In the technique described in Patent Document 1, the light emitter 2 is attached to the user's head, and the bright spot position of the light emitter 2 is monitored by a position measuring device arranged in the box 4. Accordingly, it is possible to determine whether or not the bright spot position at the time of impact (that is, the head position at the time of impact) is deviated from the bright spot position at the time of address (that is, the head position at the time of address).

  It is possible to determine whether or not the sway is performed by the above three general methods or the technique described in Patent Document 1.

  However, these methods and techniques have various problems. That is, for example, the problem described below.

  As for the method of swinging while looking at the mirror described above (1), a mirror that can reflect the whole body is installed, and places where a golf swing can be performed are limited. Also, as a real problem, it is impossible to look at the mirror while swinging while reproducing the usual form. Therefore, it remains unknown when the sway has occurred during the swing.

  In addition, regarding the method of (2) having a third party such as a lesson professional check the swing, the lesson professional is not always close to the person. Even if there is a lesson pro, it is difficult for the lesson pro to find a sway during the swing and point out the occurrence of the sway before the end of the swing. Therefore, even if advice can be received after the end of the swing, the occurrence of sway cannot be known in real time during the swing.

  Further, with regard to the above-described method (3) of photographing with a video camera and viewing the photographing result, the photographing result is seen after the end of the swing, and the occurrence of sway cannot be known in real time during the swing.

  In the technique described in Patent Document 1, only a sway during impact can be determined, and a sway during backswing and downswing cannot be detected. Therefore, it is not known at which point in the series of swing movements the sway occurs. Further, even if the sway is made during the swing, if the head position is returned at the time of the impact, it is not known that the sway has occurred during the swing.

  Thus, no matter which method and technique are used, the occurrence of sway cannot 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 that allow a user to detect that a sway has occurred even during a swing.

  According to the first aspect of the present invention, the movement of the head of the user while the user is swinging is measured, and the movement of the head satisfies a predetermined criterion at least during the measurement. A sway detection device is provided that performs a predetermined output at a time point.

  The sway detection device provided by the first aspect will be described. A general technique including the cited document 1 is a configuration in which measurement is performed during a swing and a measurement result is output after the end of the swing. However, since the present invention outputs “at the time” when the movement of the head satisfies a predetermined standard “at least during the measurement”, even during the measurement of the swing, that is, during the swing. Output is done. For this reason, it is possible to output where the head has moved in the swing operation and where the head has moved. For example, there is an advantageous effect that it is possible to know at which stage the head has moved from the address to the top position, to the top position, from the top to the impact, and then to the follow-through.

  The movement of the user's head may be measured by, for example, installing a measurement unit such as a sensor outside the user and observing the user from the outside of the user, for example. For example, the user may be observed with a camera, a radar, or the like from the user's side, back, top, front, or the like. In particular, a measuring unit such as a sensor may be installed outside the user so as to directly observe the user's head. As a better configuration, a measurement unit that measures the movement of the user's head is installed. This is because the movement of the user's head can be directly measured. In particular, an output unit that performs predetermined output may be provided on the head.

  According to the second aspect of the present invention, it is preferable that the predetermined output is detected by the user during a swing.

  The sway detection device provided by the second aspect will be described. In general techniques including the cited document 1, it is assumed that the measurement result is output after the end of the swing. Therefore, the viewpoint of telling the output to the user during the swing has been 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, there is an advantageous effect that only one person can correct and check the swing at a practice field or the like. As a configuration, it is preferable to detect at least one of the five senses of a user who is not restrained by a swing.

  When the sway detection device detects a sway, it is preferable that the sway detection device outputs some output to a sensory organ that is not restrained during a 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, and the user can detect the output by sound. Similarly, for example, a sway detection device may be attached to a user's ear or the like, and when the sway detection device detects a sway, the sway detection device may vibrate. This is because the tactile sensation of the user's ear is not constrained by the swing, and the user can detect the output due to vibration. In addition, for example, sound output and vibration may be combined. This is because the user can more reliably detect the output.

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

  The sway detection device provided by the third aspect will be described. The present invention detects a sway during a swing and outputs a predetermined output. However, a sway does not always occur once during a swing, and may occur multiple times. In such a case, if the output is performed only once, the second and subsequent sways cannot be detected (recognized). However, according to the present invention, even if there are multiple sways, as is clear from the description that “every time” is performed that satisfies a predetermined standard, an output is performed each time each sway occurs, and the user Can be detected each time.

  Further, according to a fourth aspect of the present invention, the predetermined reference is a reference related to any one of a position, speed and acceleration applied to the movement of the head, or a combination of two or more thereof. It is good to be characterized.

  The sway detection device provided by the fourth aspect will be described. The present invention detects the occurrence of sway from various viewpoints by using speed and acceleration as a reference. For example, if only the positional deviation is used as a reference and the speed and acceleration are also used as a reference, the occurrence of a sway may be detected from various viewpoints. As a result, for example, a rapid sway at a high speed or a high acceleration can be detected although the position is not so shifted. As a result, the user can detect that a sway that is not misaligned but should be corrected by practice has occurred.

  Further, according to a fifth aspect of the present invention, the predetermined reference may be determined and / or corrected based on a measurement result with respect to a past swing.

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

  Further, according to a sixth aspect of the present invention, any selection of a past swing is accepted from the user, and the predetermined reference is determined and corrected based on a measurement result of the selected past swing. It is good to be characterized by doing both or both.

  The sway detection device provided by the sixth aspect will be described. As described 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 who becomes a user, but it is preferable that there is some objective index for the user himself / herself to appropriately set this. . 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 traveled the longest among the past swings, a swing that flew straight, or a swing that is determined to be appropriate by having the user check with a third party such as an instructor. That is, a swing that is considered to be ideal among the past own swings is selected based on an objective index for the user, such as the result actually given to the ball and the subjectivity of the third party. Based on the selected swing, a predetermined reference is set. For example, by using the measured value of the selected swing as a predetermined reference, it is detected as a sway when it deviates from the movement at the time of the selected swing. Thereby, it is possible to practice to reproduce the selected ideal swing. Further, for example, instead of a swing that is considered to be ideal, or a swing that is considered to be ideal, a swing that is considered to have generated 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 the swing selected as the ideally considered swing and the amount of movement of the head of the swing considered to have caused the sway It is good.

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

  The sway detection device provided by the seventh aspect will be described. It is possible to allow the user to set an arbitrary standard. Moreover, the reference once set can be corrected. Thereby, for example, it becomes possible to set a reference for detecting a sway according to the user's preference.

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

The sway detector provided by the eighth aspect will be described. In the present invention, it may be configured to make a determination regarding a predetermined condition using various measurement values. For example, it may be configured to determine that a predetermined criterion is satisfied even if the vertical sway amount is smaller than the horizontal sway amount.
Thus, even if there is a sway that should be detected from the viewpoint of practice of swing and cannot be detected based on a certain measurement value, it can be detected by using another measurement value.

  Furthermore, according to a ninth aspect of the present invention, the predetermined reference may be made different depending on the direction in the three-dimensional space.

  The sway detector provided by the ninth aspect will be described. For example, when the determination is made based on the magnitude of the movement distance, the sway in the left-right direction may be allowed to some extent, but the sway in the vertical direction may be determined strictly. For example, there is a methodology that it is better not to sway at all, but in this way, for example, a methodology that allows a sway in the right direction to some extent can be handled. In this case, it is preferable to make the reference values different between the right direction and the left direction.

  Further, according to the tenth aspect of the present invention, the predetermined reference may be made different at a certain time point during the swing and at other time points other than the certain time point.

  If the sway detection device is provided according to the tenth aspect, the predetermined reference can be made different during a series of swings. For example, it is difficult to generate a relatively large sway during the backswing at the beginning of the swing, so the standard is tightened. On the other hand, a relatively large sway is likely to occur during the downswing, so the standard is relaxed. A configuration is good.

  Further, according to the eleventh aspect of the present invention, the user receives and receives an input from the user regarding at least one of club type information, user gender information, and user physique information used for the swing by the user. The predetermined reference may be made different based on the information.

  The sway detector provided by the eleventh aspect will be described. When the club used for the swing, the gender of the user, the physique of the user, and the like are different, the size of the sway tends to be different. Therefore, it is possible to input information such as the club used for the swing, the gender of the user, and the physique of the user, and set a predetermined standard corresponding to the tendency.

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

  The sway detector provided by the eleventh aspect will be described. By varying the output according to the standard, the user who has detected the output can know which standard he / she has met and which sway has been detected. For example, it is possible to know whether it has moved to the right, moved to the left, or moved at a speed higher than a predetermined speed.

  Furthermore, according to a 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 Display means for displaying the movement of the head along the time series during the swing based on the recorded contents.

  A sway detector provided by the thirteenth aspect will be described. According to the present invention, it is possible to grasp the movement during the swing over time along the time series, instead of displaying only about a certain point in the swing. As a result, the user can grasp how and how the sway is generated at which stage during the swing.

  Further, according to the fourteenth aspect of the present invention, the measurement may be started when a predetermined operation of the user is detected.

  A sway detector provided by the fourteenth 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 hit by the club. The measurement may be terminated based on the detection.

  A sway detector provided by the fifteenth aspect will be described. Measurement can be automatically terminated based on the detection of impact.

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

  Furthermore, according to a seventeenth aspect of the present invention, the measurement is preferably performed using an acceleration sensor.

  Further, according to an eighteenth aspect of the present invention, the measurement is preferably performed using an acceleration sensor and a gyro sensor.

  Furthermore, according to a nineteenth aspect of the present invention, there is provided a sway detection program for causing a computer to function as the sway detection device provided by any one of the first to eighteenth aspects of the present invention. Provided.

  A sway detection program provided according to the nineteenth aspect will be described. The above program can also realize the sway detection device provided by any one of the first to eighteenth aspects of the present invention described above.

  According to the present invention, a user can detect that a sway has occurred during a swing.

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

  As shown in FIG. 1, the sway detection device 100 according to 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 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 form of an earphone or a headphone as an example of the present embodiment. Then, the sway detection device 100 is worn and used on the ear of the user who performs the golf swing.

  The sound output unit 101 outputs a sound when a sway occurs based on the control of the control unit 105. The user can recognize that a 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 is referred to as “sway detection sound” for convenience of explanation. The sound output unit 101 is realized by a sound output mechanism provided in a general earphone.

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

  The external connection unit 103 is an interface for connecting the sway detection device 100 to an external device. The sway detection device 100 is driven by a battery not shown. The battery is supplied with power through the external connection unit 103 and is charged. The external connection unit 103 is also used for data transmission / reception with an external device.

  The vibration unit 104 vibrates when a sway occurs based on the control of the control unit 105. The user can recognize the occurrence of the sway by feeling the vibration by the vibration unit 104. Hereinafter, the vibration generated by the vibration unit 104 is referred to as “sway detection vibration” for convenience of explanation. The vibration unit 104 is realized by a small motor, for example.

  The control unit 105 is a control unit that controls the entire sway detection device 100, and various processes described below are realized by the control unit 105 controlling other functional blocks. Specifically, the control unit 105 includes an arithmetic processing device, and the arithmetic processing device is operated based on a program specific to the present embodiment 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 referred to as a gyro sensor) that measures the angle and speed of the user's head, an acceleration sensor that measures the acceleration of the user's head, or a combination of these sensors. The

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

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

  A specific example of a measurement target by the sensor unit 106, a specific example of a detection criterion, a method of using a measurement history, and the like will be described later.

  Next, the operation of this 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 power or start measurement. As a result, each part of the sway detection device 100 is activated, and the sensor unit 106 starts measuring the movement of the user's head (step S11).

  When the measurement is started, the sensor unit 106 outputs a 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 from the sensor unit 106, stores the measurement result in the RAM provided in the control unit 105, and compares the detection standard stored in the detection standard storage unit 107 with the input measurement result. Thus, it is determined whether or not the measurement result satisfies the detection criterion (step S12).

  If the measurement result satisfies the detection standard (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 a sway detection sound. Similarly, the control unit 105 instructs the vibration unit 104 to generate sway detection vibration.

  The sound output unit 101 outputs a sway detection sound to the user in response to the instruction. The vibration 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 with the senses of hearing and tactile sensations around the ears that are not constrained by the swing. Thereby, the user can detect that the movement of his / her head has been swayed.

  On the other hand, when the measurement result does not satisfy the detection standard (No in step S12), the process proceeds to step S14. Moreover, it progresses to step S14 also after completion | finish of step S13.

  In step S14, it is determined whether a predetermined time has elapsed since the start of measurement in step S11. Here, the length of the predetermined time can be arbitrarily determined. For example, it is set to a sufficient length from the start of one swing to the end of the swing. For example, it may be a general time required for one swing, or a time required for practice of a series of swings. Further, the user may be able to select or specify a predetermined time. 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 measurement result history stored in the RAM provided in the control unit 105 in step S12 is stored in the measurement history storage unit 108 as a measurement history. Specifically, the measurement content and measurement date and time for the current user's swing are linked and stored. Thereby, the operation of the present embodiment ends.

  Then, the effect which this embodiment has is explained.

  In the present embodiment described above, an output to the user is performed based on the detection of the sway, and the user detects the output by the senses of hearing or tactile sense around the ears that are not restricted by the swing. Thereby, the user can detect that the movement of the user's own head has been swayed.

  Moreover, since the process of step S12 and step S13 is performed without questioning whether or not the swing is in progress, the user can detect the occurrence of the sway in real time even during the swing.

  Furthermore, since the processes in steps S12 and S13 are performed as quickly as possible, the user can immediately detect the occurrence of a sway when a sway during a swing occurs. Therefore, it becomes possible to know at which stage of the swing the sway has occurred. For example, there is an effect that it is possible to know at which stage the sway has occurred, from the take-back from the address to the top position, the impact from the top, and the subsequent follow-through. For example, the comparison of the measurement result input from the sensor unit 106 in step S12 and the detection reference may be repeatedly performed every tens of milliseconds at the latest.

  Subsequently, as a modification of the above-described embodiment, a case will be described in which the host device 200 that is a host device connectable to the above-described sway detection device 100 and the above-described sway detection device 100 are connected and used.

  First, 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 part 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 information displayed on the display unit 201 include a user interface that is referred to when the user performs an operation, and information that allows the user to grasp a 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 various processes described below are realized by the control unit 204 controlling other functional blocks. Specifically, the control unit 204 includes an arithmetic processing device, and the arithmetic processing device performs arithmetic processing based on a program unique to the present embodiment stored in the control unit 204 or other storage unit, The host device 200 is realized by controlling each hardware based on the calculation result.

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

  In the measurement history storage unit 108 of the sway detector 100, the position, speed, acceleration, and the like of the head at each time point during the swing of the past swing are stored as a measurement history along a time series. 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. Based on the measurement history, the movement of the user's head during the swing is displayed.

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

  In this example, it is understood that the user's head moves most in the direction from the center to the right when the top of the user is the center and the front of the user is the upper side. In addition, it can be seen that the user's head did not move in the diagonally right front and diagonally right backward directions. Also, as shown in FIG. 4, an image diagram representing the state of the user viewed from the side is displayed on the right side of the display unit 201. 4, the movement of the user's head is indicated by an arrow on the image diagram representing the user. In this example, when the user's head is used as a reference and the zenith direction is on the upper side and the ceiling direction is on the lower side, it can be seen that the user's head is moving more upward than below. The length of the arrow corresponds to the magnitude of the movement of the user's head.

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

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

  As shown in FIG. 5, as in FIG. 4, an image diagram representing the state of the user viewed from above and an image diagram representing the state viewed from the side are displayed. However, FIG. 5 differs from FIG. 4 in that the movement trajectory along the time series of the swing is shown as a display representing 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 moved to the left side with the swing. It can also be seen that the user's head has moved slightly forward along with the swing. The point that the color and thickness of the arrow may be changed is similar to the example shown in FIG. 4 and 5 may be switched by a switching button for switching. Alternatively, the display of FIG. 4 and the display of FIG. 5 may be performed simultaneously, such as performing the display of FIG. 4 on the upper side of the screen and the display of FIG. 5 on the lower side of the screen.

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

  It is also possible to display a plurality of swing movements on the screen at the same time. By doing so, for example, the head movement during a past favorable swing (for example, a swing with a long flight distance or a swing in which a ball flew straight) is compared with the head movement of the current swing. It becomes possible. By referring to this screen, the user can grasp how the swing has been made in the same manner as a certain preferred swing in the past. In addition, it is good also as a structure which designates the swing used for determination of the detection reference mentioned later from this movement of the displayed multiple times of swing.

  By connecting the host device 200 including the display unit 201 to the sway detection device 100 in this manner, the head movement during the swing can be visually recognized.

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

  As an object to be measured by the sensor unit 106, for example, a measurement value related to the magnitude and direction of the movement distance of the user's head, a measurement value related to the magnitude and direction of the movement speed of the user's head, and a movement acceleration of the user's head. The measured value regarding the magnitude | size and direction of can be illustrated.

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

  In step S12, when the measurement result of the sensor unit 106 exceeds these threshold values, it is determined that the standard is satisfied. In addition, you may make it judge that the reference | standard was satisfy | filled when the measurement result of the sensor part 106 continues exceeding these threshold values for the predetermined time length. The predetermined time may be, for example, a time that can be generally considered that a sway has occurred. For example, it may be a case where 200 ms or more are continued. In addition, if any one threshold is exceeded or if any one threshold is exceeded, it may be judged that the standard is satisfied, but if more than one threshold is exceeded or if more than a plurality of thresholds are exceeded It is also good to judge that the standard is satisfied.

  Further, it may be determined that the criterion is satisfied when the integrated value of the measured values during a predetermined time exceeds the threshold value instead of the measured values themselves.

  Furthermore, the direction may be taken into consideration. In this case, for example, when the measurement result of the sensor unit 106 in a certain direction or the integrated value of the measurement result exceeds a threshold value, it may be determined that the standard is satisfied.

  For example, generally, the sway with respect to the direction in which the ball is thrown is small, and the sway in the opposite direction tends to be large. For example, if the ball is thrown in the direction of the user's left foot, the user's head will greatly sway in the direction of the right foot. Therefore, the threshold value for the user's right foot direction may be set larger than the threshold value for the left foot direction. Also, for example, if there is a tendency that the sway becomes larger during 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 elapsed 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 illustrating a state at the time of impact of a golf swing, and illustrates 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 the golf ball 302 with a golf club 301 such as an iron, it is necessary to put 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, when the golf club 301 moves up and down within the range of 20 mm, it tops up or duffs and the golf ball 302 cannot be properly blown. For this reason, it is preferable to set the detection standard with an accuracy capable of detecting a sway that leads to a vertical movement within the range of at least 20 mm. For example, the detection reference may be set with an accuracy that can detect a sway that leads to a vertical movement of about 5 mm.

  Next, the operation for 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, even if the person is the same, it is considered that the sway becomes smaller as the swing progresses. Therefore, it is preferable that the detection criteria can be determined and corrected by the user.

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

  In addition, for example, it is also possible to automatically correct a threshold value that is a detection criterion based on a sway detection status or the like instead of being triggered by a user operation reception. For example, the threshold value is corrected to a large value when the swing in which the sway has occurred reaches a predetermined number, and the threshold value is corrected to a small value when the swing in which the sway has not occurred reaches a predetermined number. It is good to make it.

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

  Further, for example, it is considered that a person with a large physique tends to have a larger sway than a person with a small physique. For this reason, the threshold value may be determined accordingly. Moreover, 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 possible to accept an input for selecting gender so that the threshold value is greater for women than for men. These settings may be configured such that a setting screen is displayed on the display unit 201 of the higher-level device 200, and the setting contents are determined and corrected in accordance with an input instruction from the operation receiving unit 203. In this case, the setting content may be transferred to the sway detection apparatus 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 content transferred from the host device 200 in this way.

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

  If the user constantly measures without detecting the start and end of the user's swing, if the user walks around with the sway detector 100 attached, a sway detection sound will sound when the user is not swinging. It is conceivable that Therefore, in the above-described embodiment, the measurement is started when the user's operation is accepted in step S11. In addition, the measurement was terminated when a predetermined time passed in step S14. However, it is better that the measurement can be started by deforming this and automatically detecting the start of the swing. It is even better if the end of the swing can be automatically detected to end the measurement.

  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 at least the movement of the user's head from the time when the address is entered until the moment of impact. Therefore, in the following description, the address and the moment of impact are detected. Then, measurement by the sway detector 100 is started when it is detected that the address has been entered. Further, after detecting the moment of impact, it is considered that no further swing measurement is necessary, so the sway detector 100 ends the swing measurement and stops the head movement monitoring. There is also the idea that it is better not to move the head for a while after entering the follow-through as a swing methodology. If this idea is followed, it is recommended to monitor the movement of the head for a while after entering the follow-through by detecting the moment of impact and continuing the measurement for a predetermined length of time. .

  Next, three examples of specific configurations for detecting an address entry and an impact moment will be described.

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

  The video acquisition unit 205 captures the video of the user performing the swing, and the image recognition unit 206 determines whether the video has entered the address and the moment of impact by image recognition.

  When the image recognition unit 206 recognizes that the address has been entered, the control unit 204 of the higher-level device 200 indicates that the swing has started to the sway detection device 100 via the external connection unit 202 and the external connection unit 103. Send a signal. 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 regard, it is necessary to prevent the image recognition unit 206 of the host device 200 from performing a user swing before address recognition, that is, before measurement is started. Therefore, for example, the notification unit 207 of the higher-level device 200 may notify the user that the address has been recognized. For example, the notification unit 207 is realized by an LED (Light Emitting Diode) or the like. Then, at the same time as the address recognition is completed by the image recognition unit 206 of the host device 200, the notification unit 207 is turned on. The user starts takeback after seeing the lighting of the notification unit 207. Thereby, the situation where a swing is performed before the start of measurement can be prevented. Further, when the address recognition is completed by the image recognition unit 206 of the host device 200, it is recognized that the address has been entered by outputting sound and vibration by the sound output unit 101 and the vibration unit 104 of the sway detection device 100. It is also possible to notify the user to the effect. Then, the user may start takeback after receiving the notification.

  When the image recognition unit 206 of the host device 200 can recognize the moment of impact, the control unit 204 of the host device 200 completes 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 human sensor 208 in addition to the configuration of FIG. The human sensor 208 is a sensor for detecting the location of the user 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. When the human sensor 208 detects that there is a user in front of the host device 200, the control unit 204 of the host device 200 passes through the external connection unit 202 and the external connection unit 103 to the sway detection device 100. A signal indicating that there is a user in front of the host device 200 is sent.

  When the sway detection device 100 receives a signal indicating that there is a user in front of the host device 200, the sway detection device 100 enters the play mode. When a tilt state that seems to be the user's address posture (for example, holding the same posture for 2 seconds) is detected during the play mode, it is recognized that the address has been entered, and monitoring of head movement is started (step S11). .

  When the human sensor 208 detects that there is no user before the host device 200, the control unit 204 of the host device 200 connects the external connection unit 202 and the external connection unit 103 to the sway detection device 100. The user sends a signal indicating that there is no user in front of the host device 200. When the sway detection device 100 receives a signal indicating that there is no user before the host device 200, the sway detection device 100 turns off the play mode and ends the measurement (corresponding to Yes in step S14).

  Furthermore, as a third configuration, a configuration in which a device that performs a measurement related to a swing as described in Patent Document 2 and Patent Document 3 and a host device 200 are combined, and a function that performs a measurement related to a swing in the host device 200 is further provided. A configuration of adding can be considered.

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

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

  If such a measuring device is used, it can be determined that the address has been entered at the moment when the measured head speed becomes almost zero. Furthermore, the moment of impact can be detected from a change in either or both of the measured head speed and ball speed. Therefore, a series of movements during the swing can be measured by starting and ending the measurement of the sway detection device 100 based on these determinations and detections.

  Moreover, if the apparatus described in the cited document is utilized, an estimated flight distance can be derived from either the measured head speed or ball speed. Therefore, it is preferable to display the head speed, the ball speed, and the estimated flight distance. By referring to these pieces of information, for example, the user can compare the head movement when the estimated flight distance is long with the head movement when the estimated flight distance is short.

  Furthermore, as another method, the end of the swing may be determined based on a change in the measurement value by the sensor unit 106, instead of changing the configuration. For example, since it is considered that the head movement 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.

  In addition, it is common to detect the address posture by any method, but if it takes too much time to detect the address posture, the timing for the user to take back becomes difficult or the body becomes stiff. It is considered that a smooth swing cannot be performed. For this reason, it is preferable to detect the address posture by a method that requires as little time as possible.

  Although the embodiment described above is a preferred embodiment of the present invention, the scope of the present invention is not limited only to the above-described embodiment, and various modifications are made without departing from the gist of the present invention. Implementation is possible.

  For example, in the above description, the sway detection device 100 is realized by an earphone-shaped device. However, this is only one example of implementation and other shapes may be employed. In particular, the shape may be attached to the user's head. For example, the shape may be a headphone shape, a glasses shape, a haircut shape, a headband shape, a headband shape, a hat shape, an earring shape, or the like.

  Furthermore, 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, the sensor unit 106 may be provided in the earphone-shaped first device, and the measurement result may be transmitted to the other 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 based on an instruction from the second device The sway detection sound or the sway detection vibration may be output to the 101 or the vibration unit 104. This also makes it possible to reduce the size of the first device.

  In the above description, both the sway detection sound and the sway detection vibration are output. However, either one may be output. Accordingly, it is sufficient to provide only one of the sound output unit 101 and the vibration unit 104. In addition, if the output acts on the five senses that are not restrained during the swing, the detection of the sway may be output by a method other than sound or vibration.

  It is also preferable to use a plurality of types of notification methods. For example, a plurality of sway detection sounds are prepared by varying the pitch and the length of sound. A different output is associated with each of the plurality of detection standards. By doing so, it becomes possible for the user to grasp which detection criterion 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 up / down direction occurs, the user swayes his / her head in the up / down direction. It is possible to grasp whether the sway is left or right.

  In addition, 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). Furthermore, it is particularly preferable that the external connection unit 103 and the external connection unit 302 are realized by a module for wireless communication, and data is transmitted and received by wireless communication. In this way, the degree of freedom of movement of the user's body is increased and the swing is not easily disturbed. Moreover, the freedom degree of installation of the high-order apparatus 200 can be raised.

  In addition, as shown in FIG. 2, in the present embodiment, output is performed every time the detection criterion is satisfied if the predetermined time has not elapsed or before the impact is detected. That is, it is assumed that there can be a plurality of outputs during one swing, but if the output occurs frequently, it may be difficult to recognize at which stage during the swing the sway has occurred. Therefore, the number of outputs in one swing may be set to a predetermined number or less, for example, only once and only twice. In the case of such a configuration, after step S13, there is further provided a step for confirming whether the output number is equal to or less than the predetermined number. If the predetermined number is exceeded, the determination in step S14 is not performed. The process may proceed to step S15. Thereby, the certainty of detection by the user of output improves.

  In the above-described embodiment, the measurement history is used. However, a device that performs sway detection without using the measurement history may be used. In the case of such a configuration, the measurement history storage unit 108 can be omitted. Moreover, the process of step S15 is also unnecessary. Further, the measurement history storage unit 108 may be provided in the upper apparatus 300.

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

  The sway detection device described above can be realized by hardware, software, or a combination thereof. The communication method performed by the above sway detection device can also be realized by hardware, software, or a combination thereof. Here, “realized by software” means realized by a computer reading and executing a program. For example, some processes may be executed by an external device such as a server connected via a communication line.

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

  Moreover, although the above-described embodiment is a preferred embodiment of the present invention, the scope of the present invention is not limited only to the above-described embodiment, and various modifications are made without departing from the gist of the present invention. Implementation in the form is possible.
