Description

  The present invention relates to a golf support system for performing measurement relating to a swing of a golf club, a golf support apparatus and a program for implementing the system, and in particular, a measurement result relating to a swing of a golf club and a swing performed by this measurement. The present invention relates to a golf support system, a golf support apparatus, and a program capable of finding the optimal swing tempo for each user based on the correlation with the tempo.

  Conventionally, practice has been made to swing a golf club in accordance with the tempo of the metronome, and to correct the swing timing to a tempo that suits you. As conventional metronome devices used for golf club swing practice, for example, Japanese Patent Application Laid-Open No. 9-154991 (Patent Document 1), Japanese Patent Application Laid-Open No. 9-271554 (Patent Document 2), and Japanese Patent Application Laid-Open No. 2000-51422 ( There are some which are indicated by patent documents 3) and JP, 2004-86140, A (patent documents 4).

  However, the conventional metronome devices as disclosed in Patent Documents 1 to 4 all generate only a constant tempo (or a rhythm when accented beats are repeated periodically). There is a problem that it is not possible to find an optimum tempo for the user only by swinging in accordance with the tempo generated by the apparatus.

  In other words, the optimum tempo for the user must be a timing at which, for example, the head speed, ball speed, ball meet ratio, hole flight distance, etc. are favorable when swinging at that tempo. In swing practice using a conventional metronome device, the tempo of the swing and the result of the swing are not linked, so the correlation between what tempo and what result is obtained is unknown.

  For this reason, in the conventional metronome device, even if the user feels that the swing tempo is suitable for him, this tempo is not necessarily a tempo that leads to a good result. In addition, the tempo suitable for the user varies depending on gender and age, and is not always constant. Therefore, unless a swing practice is performed at different tempos and the results of swinging at these tempos are compared, the optimum tempo for the user cannot be found. Nonetheless, there has never been a system or device that correlates the swing tempo and the result of the swing and statistically analyzes the correlation between the two.

  The present invention has been made in view of the above problems, and based on the correlation between the measurement result relating to the swing of the golf club and the tempo of the swing performed in this measurement, the optimum tempo of swing for each user. It is an object of the present invention to provide a golf support system, a golf support apparatus, and a program that can find a game.

(1) In order to achieve the above object, a golf support system according to the present invention is a golf support system for measuring a swing of a golf club, and includes a control means for measuring a head speed and auditory, visual or The control means includes notification means for performing notification that can be sensed by tactile sense, and metronome means for causing the notification means to perform a series of swing support notifications that repeat unit notification at a predetermined tempo set in advance during the measurement. The measurement result related to the head speed is stored in association with the tempo of the swing support notification performed at the time of the measurement.

  According to the above configuration, it is possible to find the optimum swing tempo for each user based on the correlation between the measurement result regarding the head speed of the golf club and the swing tempo performed in this measurement.

  As a method of finding the optimum tempo using this golf support system, for example, swing practice is started from a relatively slow tempo, and the head speed is measured by gradually increasing the tempo. The estimated flying distance of the ball is calculated from the head speed corresponding to each tempo (which may be the ball speed described below), and attention is paid to the correlation between each tempo and the estimated flying distance. In this correlation, since there is a place where the estimated flight distance does not change even if the tempo is increased, the tempo is the user's reference tempo. Thereafter, swing practice is performed in the vicinity of the reference tempo, and for example, a tempo in which measurement results such as head speed, ball speed, meat rate, estimated flight distance, etc. are stably high may be set as the user's optimum tempo.

  Although this is not the optimum tempo for the user, the tempo when the highest head speed value is recorded may be a tempo suitable for the user.

  Here, the “measurement relating to the head speed” in the present invention is not limited to the measurement of the head speed itself, but is a secondary measurement derived from the measurement result of the head speed (ex. Ball meet rate, estimated flight distance, etc.). Measurement). “Notification that can be sensed by hearing, vision, or touch” widely includes, for example, notification using one or a combination of two or more of sound, light, vibration, and the like. “Tempo” is the speed at which a beat is beaten, and a series of “swing support notifications” is formed by repeating “unit notifications” such as sound, light, and vibration corresponding to the beats at a predetermined tempo. Is done. Generally, the tempo is specified by the number of beats per minute (Beat Per Minute = BPM).

(2) Preferably, the control means performs a measurement on the ball speed of the ball hit on the club head, and a measurement result on the ball speed and a tempo of the swing support notification performed at the time of the measurement. It is good to make it the structure which matches and memorize | stores.

  According to the above configuration, it is possible to derive the correlation between the ball speed of the ball hit on the club head and the swing tempo at that time. In addition, based on the head speed measurement result and ball speed measurement result described above, the ball meet rate described below can be calculated, and the correlation between the meet rate and the swing tempo can be derived. It becomes. Further, the estimated flight distance of the ball can be calculated based on the measurement result of the ball speed, and the correlation between the estimated flight distance and the swing tempo described above can be derived. In particular, in practice using a golf club such as a putter where the swing stroke is short and the head speed cannot be measured, the estimated flight distance of the ball can be calculated based on the ball speed measurement result. From the correlation between the flight distance and the tempo, it is possible to find the optimum stroke tempo of the putter.

  Here, “measurement of the ball speed” is not limited to the measurement of the head speed itself, but a secondary measurement derived from the measurement result of the head speed (ex. Measurement of the ball's meat rate, estimated flight distance, etc.). It also includes the meaning. Further, the ball speed itself may be measured as long as it measures at least the initial speed of the ball hit on the club head.

(3) Preferably, the control means calculates a meet rate based on a measurement result related to the head speed and the ball speed, and the calculation result of the meet rate and the swing support notification performed at the time of the measurement. It is preferable to store the tempo in association with each other.

  According to the above configuration, the correlation between the meet rate and the swing tempo can be derived. This “meet rate” is an index representing how efficiently the swing of the golf club can be transmitted to the ball. The higher the meet rate, the more stable the swing, and the tempo of the swing when the high meet rate is recorded may be the reference tempo described above or the optimum tempo. Such a meet rate is calculated by ball speed (initial speed) / head speed.

(4) Preferably, the control means calculates an estimated flight distance of the ball based on a measurement result relating to the head speed or the ball speed, and the calculation result of the estimated flight distance is performed at the time of the measurement. The tempo of the swing support notification may be stored in association with each other.

  According to the above configuration, it is possible to derive a correlation between the estimated flying distance of the ball and the tempo of the swing. In order to increase the score of golf, it is extremely important to extend the flight distance of the ball, and the correlation between the estimated flight distance and the tempo is an important judgment material when the user selects the optimum tempo. The “estimated flight distance of the ball” can be calculated based on the head speed or the ball speed (initial speed) described above.

(5) Preferably, the metronome means adds an accent to the predetermined unit notification among the unit notifications forming the swing support notification, and in the swing support notification, the accented unit notification, It is good to make it the structure which the time signature which does not have the said unit alerting | reporting repeats periodically.

  According to the above configuration, in the swing support notification, accented unit notification is periodically repeated, and a constant rhythm can be formed in the swing support notification. This makes it easy to match the swing timing to the tempo of the swing support notification. Here, “accenting” in the present invention means attaching a distinction that can be sensed by auditory, visual, or tactile sense to a predetermined unit notification that constitutes the time signature. For example, when the unit notification is a sound, it is possible to add accents by changing the strength, height, shortness, kind, etc. of the sound. In addition, when the unit notification is light, accents can be added by varying the intensity of light, color, light emission time, and the like. Furthermore, when the unit notification is vibration, accents can be added by varying the vibration intensity, length, frequency, amplitude, and the like. In the present invention, an accent may be attached to any unit notification that constitutes the time signature. For example, if the swing support notification is performed in three beats, the first, second, and third unit notifications may be accented according to the user's preference.

  The “time signature” generally refers to a collection of a certain number of beats composed of a combination of strong and weak beats, and is a unit forming a rhythm. “Rhythm” generally refers to the periodic repetition of accented beats. In the present invention, it may be a tempo-only swing support notification composed of unit notifications without accents, or a tempo and rhythm swing support notification in which accented unit notifications are periodically repeated.

(6) Preferably, when the measurement is performed a plurality of times, the metronome means performs the swing support notification in which at least one of tempo or time signature is different, and the control means performs the measurement result or the calculation result of each measurement. It is preferable to store statistical data in which at least one of the above and at least one of the tempo or the time signature of the swing support notification performed at each measurement are associated with each other.

  According to the above-described configuration, for example, the swing support notification tempo and time signature can be varied step by step, and multiple swing exercises can be performed, and the measurement results of each swing exercise can be recorded statistically. Become. As a result, for example, swing practice can be performed in which the tempo is increased gradually from a slow tempo, and an optimal tempo suitable for the user can be easily found based on the correlation between each tempo and the estimated flight distance.

  Here, the swing support notification tempo may be set in a range of about 20 to 120 BPM in consideration of all users such as men, women, adults, children, the elderly, professionals, and amateurs. Moreover, the time signature of the swing support notification may be set to a range of about 2 to 6 time signatures, for example.

  The tempo and time signature of the swing support notification are operation timings when performing a swing, and both affect the head speed. For example, a male professional golfer swings at a tempo of about 80-100 BPM, and a female professional golfer swings at a tempo of about 70-80 BPM. On the other hand, the time signature of the swing is various, such as 2 beats, 3 beats, 4 beats, 5 beats, and 6 beats. For example, when a swing is performed with two beats, an address is performed with one beat, a top swing is performed with two beats, and impact to follow-through are performed. When swinging in 3 beats, 1 beat is addressed, 2 beats are top swing, 3 beats are from impact to follow-through. When swinging with 4 beats, check shot direction with 1 beat, address with 2 beats, top swing with 3 beats, impact to follow through with 4 beats. In addition, in consideration of customs when performing a swing, there are cases where the time is 5 beats, 6 beats or more.

(7) Preferably, the control means, based on the statistical data, at least one of the measurement result or the calculation result of each measurement, and at least the tempo or time signature of the swing support notification performed at the time of each measurement It may be configured to display the correlation with one.

  According to the above configuration, the results of swing exercises measured at different tempos and beats are visualized in a table or graph, and the correlation between the swing tempo and beat and head speed, ball speed, meat rate, or estimated flight distance Can be easily understood. For example, when implementing the above-described method for finding the optimum tempo, if the graph with the estimated flight distance on the vertical axis and the swing tempo on the horizontal axis is displayed, the estimated flight distance will not change even if the tempo is increased. At a glance, the user's reference tempo can be easily specified.

(8) Preferably, the metronome means may be configured to change a tempo and / or a time signature of the swing support notification to be performed at the time of the measurement every predetermined number of times set in advance.

  According to the above configuration, since the tempo and time signature of the swing support notification are automatically changed without any operation by the user, the swing practice for finding the optimum tempo and time signature can be continuously performed. Is possible. Here, when practicing the present invention, notification for notifying the user of the change may be performed at a time when the tempo and time signature of the swing support notification are changed. For example, when the change notification is a sound, a sound different from the unit notification, a predetermined melody, a message voice, or the like is used. When the change notification is light, the color, the light emission pattern, the light emission time, etc. are different from the unit notification. When the change notification is vibration, the strength, length, frequency, amplitude, etc. are different from the unit notification.

(9) Preferably, the control unit performs the unit notification of the last one beat constituting the timing of the maximum value of the head speed and the time of the swing support notification performed at the time of the measurement. It is preferable that the timing difference between the swing of the golf club and the swing support notification performed at the time of the measurement is calculated by comparing the timing of the break.

  According to the above configuration, it is possible to detect a deviation between the time signature of the swing support notification selected by the user and the time signature of the swing performed by the user, and efficiently correct the tempo of the swing after grasping the degree of the deviation. It can be carried out. For example, after finding an optimal tempo using the present golf support system, the user performs swing practice at the optimal tempo. If a deviation occurs in the tempo of the swing at this time, the fact that the tempo has changed is notified by sound, light, vibration, or the like. For example, a message such as “the tempo is slow” or “the tempo is fast” is output from a speaker by voice, or such a message is displayed on the liquid crystal screen. The deviation of the swing tempo may be displayed abstractly by the light emission color of the LED. For example, when the tempo is slow, the LED is made to emit “green”, and when the tempo is fast, the LED is made to emit “red”. Further, for example, a vibration with a low frequency may be generated when the tempo is slow, and a vibration with a high frequency may be generated when the tempo is fast.

(10) Preferably, a speaker as the notification means is provided, and the metronome means outputs a sound as the unit notification from the speaker during the measurement. (11) More preferably, the notification means includes ear-mounted sound output means capable of wireless communication, and in the measurement, the metronome means incorporates sound as the unit notification in the sound output means. It is good to make it the structure output from a speaker.

  According to the above configuration, since the tempo and time signature of the swing can be adjusted while listening to the swing support notification with the ear, the user can perform the swing while concentrating on the consciousness. In particular, when the swing support notification is performed using ear-mounted sound output means capable of wireless communication, the tempo of the swing can be achieved without causing trouble to other players at golf courses and driving ranges. It is possible to perform matching. Here, “wireless communication” widely includes communication methods other than wired communication, and includes, for example, wireless communication using radio waves and infrared communication using infrared rays.

(12) In order to achieve the above object, a golf support apparatus of the present invention is an apparatus for implementing the above-described golf support system of the present invention, and functions as a Doppler sensor, the control means, and the metronome means. A microwave that is emitted from the Doppler sensor is reflected on the club head or the ball, and the head speed or the ball speed is measured based on the frequency of the reflected wave.

  According to the above configuration, the head speed and the ball speed can be measured with high accuracy using the Doppler effect, the tempo selected by the user, the head speed when the time signature is swung, the ball speed, the meat rate, and The estimated flight distance and the like can be accurately measured or calculated. Thereby, accurate data when swinging with different tempos and time signatures can be obtained, and the reliability of the tempo and time signature selected as the optimum by the user is high.

(13) In order to achieve the above object, a program of the present invention is a program for implementing the above-described golf support system of the present invention on a golf support device having a Doppler sensor, and is installed in the golf support device. Control processing is performed for causing the computer thus functioned as the control means and the metronome means.

  The program of the present invention that performs the control processing also provides the same operational effects as the golf support systems (1) to (11) and the golf support device (12).

  As described above, according to the golf support system, the golf support apparatus, and the program of the present invention, each user can be determined based on the correlation between the measurement result regarding the swing of the golf club and the tempo of the swing performed in this measurement. It becomes possible to find the optimal swing tempo.

The golf support apparatus 1 includes a microcontroller 21 as control means and metronome means. Various functions of the golf support apparatus 1 are stored as programs on the EEPROM 28 connected to the microcontroller 21, and are realized by the CPU of the microcontroller 21 executing these programs. In addition, the microcontroller 21 executes a control process of a pass / fail judgment function such as a metronome function and a measurement result of the present invention described later. Hereinafter, each component connected to the microcontroller 21 and control processing executed by the microcontroller 21 will be described.

<Doppler sensor amplifier>
The aforementioned Doppler sensor 17 is connected to the microcontroller 21 via an amplifier 22. As described above, the Doppler sensor 17 emits a microwave having an output frequency of 24.15 GHz, and outputs a signal corresponding to the frequency of the reflected wave.

The above-described three-color LED 23 is connected to the microcontroller 21. The three-color LED 23 is a notifying means for executing a measurement result pass / fail judgment function, and notifies the pass / fail judgment evaluation result with different emission colors. The microcontroller 21 determines pass / fail by comparing the measurement results of the head speed, ball speed, meet rate, and estimated flight distance with, for example, reference data shown in FIG.

  In this embodiment, three threshold values of high, medium, and low are set as reference data corresponding to each measurement result such as head speed, and the degree of pass / fail of each measurement result is determined in three steps: upper, middle, and lower. I am trying to evaluate with. When the measurement result exceeds the high threshold, the microcontroller 21 causes the three-color LED 23 to emit “blue”. When the measurement result exceeds the intermediate threshold value, the microcontroller 21 causes the three-color LED 23 to emit “yellow”. Further, when the measurement result exceeds a low threshold, the microcontroller 21 causes the three-color LED 23 to emit “red”. If the measurement result does not exceed the low threshold, the microcontroller 21 does not cause the three-color LED 23 to emit light.

When the power switch 16 is turned on, the microcontroller 21 starts the program and causes the display unit 12 to display an opening screen. Thereafter, when the activation of the program is completed, the microcontroller 21 causes the display unit 12 to display a menu screen (see FIG. 8A) on which a plurality of icons for executing various functions are arranged. When the user touches one of the icons, one of the functions is executed. Moreover, as a power supply used for this golf assistance apparatus 1, for example, an AA alkaline dry battery and a nickel hydride storage battery that are easily available in various countries are preferable, but are not particularly limited.

[How to use the golf support apparatus]
Next, a specific example of a method of using the golf support device 1 having the above configuration will be described with reference to FIGS.

  5 and 6 illustrate the case where the present golf support apparatus 1 is installed at a predetermined position behind the user U who swings the golf club C. FIG. The golf support apparatus 1 can measure the head speed and the ball speed even when installed at a predetermined position in front of the user U. Hereinafter, this golf assistance apparatus 1 is demonstrated as what is installed in the user's U back predetermined position.

  The golf support apparatus 1 is installed at a position where the detection range of the Doppler sensor 17 described above includes a point where the club head CH during the swing moves at the maximum speed. As shown in FIG. 5, the vicinity of the lowest point of the movement trajectory K of the club head CH is the impact position with respect to the ball B, and the movement speed of the club head CH is normally the maximum speed near the impact position. Therefore, the golf support apparatus 1 is installed on the tangent L at the lowest point of the movement locus K of the club head CH and at a predetermined position behind the user U.

  The distance of the golf support apparatus 1 with respect to the club head CH and the ball B at the impact position is a position where the club head CH does not hit the golf support apparatus 1 during backswing. For example, as shown in FIG. 6, the golf support apparatus 1 may be installed about 1 m behind the ball B. When the golf support apparatus 1 is installed, the antenna opening surface of the Doppler sensor 17 faces the ball B (facing the tangent L). At this time, the angle of the golf support apparatus 1 may be adjusted using the dedicated stand 40 shown in FIG. 2 so that the golf support apparatus 1 is horizontal.

  Here, the type of club used when measuring the head speed or the like with the golf support apparatus 1 may be wood, utility, iron, wedge, or putter. When the club to be used is a putter, the golf support apparatus 1 does not measure the head speed but measures only the ball speed. Then, at the time of measurement, the “used club type” is input to the golf support apparatus 1 via the touch panel 11. Then, the microcontroller 21 calculates the estimated flight distance with a coefficient corresponding to the “used club type”. The “used club type” indicates the club type together with the measurement result at that time on the display unit 12 and is stored in the memory card 26 as a history together with the measurement result and the like.

[Various functions of golf support equipment]
In the golf support apparatus 1, the microcontroller 21 shown in FIG. 4 executes a program stored in the EEPROM 28, so that “swing mode”, “practice mode”, “metronome function”, “good / bad determination function”, etc. Implement various functions.

<Swing mode>
The “swing mode” is a main function of the golf support apparatus 1 and simultaneously measures the head speed of the club head when the golf club is swung and the ball speed of the ball hit on the club head. Based on these measurement results, the meet rate and the estimated flight distance are calculated, and the measurement results of the head speed, the ball speed, the meet rate, the estimated flight distance, and the like are displayed on the display unit 12 (see FIG. 1A). In addition, the measurement result of the “swing mode” is stored in the memory card 26 as a history.

<Practice mode>
The “practice mode” is a game element added to the “swing mode” described above. For example, a target flight distance of 50 to 150 years that is optimal for approach practice is set, and the user is as close as possible to the target flight distance. To swing. If the estimated flight distance calculated based on the head speed or the ball speed at this time is within the acceptable range, the display unit 12 is notified of “nice-on display”. The target flight distance is randomly selected by the microcontroller 21 or set to an arbitrary value by the user. In addition, the user can set an arbitrary numerical range for the pass range of the estimated flight distance.

<Metronome function>
The “metronome function” is a function executed together with the “swing mode” described above. When measuring the head speed or the like, the wireless earphone 30 shown in FIG. 3 and FIG. Sound) and assist the user in taking the swing timing. Hereinafter, the “metronome function” executed by the golf support apparatus 1 will be described in detail with reference to FIGS.

<< Swing support notification >>
FIG. 7 is an explanatory diagram showing the contents of the swing support notification performed by the golf support apparatus 1. FIG. 4A shows a 3-beat, FIG. 4B shows a 4-beat, and FIG. 4C shows a swing support notification P without a beat.

  As shown in FIGS. 7A to 7C, the swing support notification P is a series of notifications that repeat unit notification (see symbols P1 and P2 in the figure) at a predetermined tempo set in advance. In this embodiment, the beep sound output from the speaker 36 of the wireless earphone 30 is used as unit notification. The tempo is the speed at which a beat is beaten, and is specified by the number of unit notifications P1 and P2 corresponding to the beat in one minute (Beat Per Minute = BPM). The swing support notification P of this embodiment has a tempo that repeats at least unit notification at regular intervals. In the present golf support device 1, for example, the user can set an arbitrary tempo in the range of 20 to 120 BPM (see FIG. 8C).

  In the present embodiment, the swing support notification P can be given a predetermined time signature. A time signature is a unit of a certain number of beats composed of a combination of strong and weak beats, and is a unit that forms a rhythm. Rhythm is the periodic repetition of accented beats. As shown in FIGS. 7A and 7B, among unit notifications forming the swing support notification P, a predetermined unit notification P1 is accented, and an accented unit notification P1 and an unaccented unit notification P2 It is possible to form a rhythm in which a predetermined time signature consisting of In the golf support apparatus 1, for example, the user can set an arbitrary time signature within a range of 2 to 6 time signatures (see FIG. 8D).

  For example, as shown in FIG. 7 (a), when the swing support notification P is set to triple time, one unit notification P1 with accent and two unit notifications P2 and P2 without accent have three time signatures. For example, it becomes a swing support notification P that repeats a beep sound of “pi!”, “Po!”, “Po!”... At a predetermined tempo. The user performs a swing in synchronization with the 3-beat swing support notification P. For example, the first beat unit notification P1 addresses, the second beat unit notification P2 performs a top swing, and the third beat unit notification P2 performs from impact to follow-through.

  Further, as shown in FIG. 7B, when the swing support notification P is set to 4 beats, one unit notification P1 with an accent and three unit notifications P2, P2, P2, P2 without an accent Form a 4-beat, for example, a swing support notification P that repeats a beep sound of “pi!”, “Po!”, “Po!”, “Po!”. The user performs a swing in synchronization with this 4-beat swing support notification P. For example, the shot direction is confirmed by the unit notification P1 of the first beat, the address is received by the unit notification P2 of the second beat, the top swing is performed by the unit notification P2 of the third beat, and the impact to the follow-through is performed by the unit notification P2 of the fourth beat. .

  On the other hand, whether or not to add time to the swing support notification P can be selected according to the user's preference. As shown in FIG. 7C, only unit notifications P2, P2, P2,. Swing support notification P can be performed repeatedly at a predetermined tempo. In this case, a plurality of unit notifications P2, P2, P2,... Without accents are repeated at a predetermined tempo, for example, “Po!”, “Po!”, “Po!”, “Po!” ... Becomes a swing support notification P without a continuous time signature. The swing support notification P without time signature can be adjusted regardless of the time of the swing, and has an advantage that the swing operation can be started from any of the continuous unit notifications P2, P2, P2,. .

<< Various settings for swing support notification >>
Next, various setting screens and operation procedures when the “metronome function” of the golf support apparatus 1 is executed will be described with reference to FIGS.

  FIG. 8A shows a menu screen for selecting various functions in the golf support apparatus 1. The menu screen displayed on the display unit 12 includes “swing icon”, “practice icon”, “bat icon”, “ball icon”, “metronome icon”, “setting icon”, and “return button”. The icons and buttons can be selected by a touch operation on the touch panel 11. The “swing icon” and “practice icon” are for selecting the “swing mode” and “practice mode” described above. The “bat icon” and “ball icon” are used to select a “baseball ball detection mode” and a “baseball bat detection mode” to be described later. The “setting icon” is for shifting to a “setting screen” for performing various settings of the golf support apparatus 1. The “return button” is for returning to the screen before the transition to the current menu screen.

  When the “metronome icon” is touched on the menu screen shown in FIG. 8A, the above-described microcontroller 21 switches the display on the display unit 12 to the execution screen for the “metronome function” shown in FIG. 8B. This execution screen includes a “tempo icon”, a “time signature icon”, a “volume icon”, a “send button”, and a “return button”, all of which can be selected by a touch operation. Among these, the “tempo icon”, “time signature icon”, and “volume icon” display the current setting contents such as “tempo: 80”, “time signature: 3”, and “volume: high”, respectively. ing. When the “Send button” is selected by touch operation in this state, the microcontroller 21 transmits information on the current setting to the wireless earphone 30, and the tempo = 80 BPM, 3-beat swing support notification P from the speaker 36 of the wireless earphone 30. Is output.

  When changing the setting of the swing support notification P, a “tempo icon”, a “time signature icon”, and a “volume icon” shown in FIG. When the “tempo icon” is touched, the display on the display unit 12 is switched to the tempo setting screen shown in FIG. In this tempo setting screen, the tempo of the swing support notification P can be set in the range of 20 to 120 BPM. The set value is input using a keyboard of “0” to “9”. When a numerical value within the range of 20 to 120 BPM is input and the “OK button” is touched, the display on the display unit 12 returns to the execution screen of FIG. On the other hand, when a numerical value outside the range of 20 to 120 BPM is input, a message “out of range” is displayed on the tempo setting screen, and the execution screen of FIG.

  When the “time signature icon” is touched, the display on the display unit 12 is switched to the time signature setting screen shown in FIG. On this time signature setting screen, the tempo of the swing support notification P can be set in the range of 2 to 6 time signatures. The set value is input using the keyboards “2” to “6”. When a numerical value within the range of 2 to 6 beats is input and the “OK button” is touched, the display on the display unit 12 returns to the execution screen of FIG. On the other hand, when a numerical value outside the range of 2 to 6 beats is input, a message “out of range” is displayed on the time signature setting screen, and the screen returns to the execution screen of FIG.

  When the “volume icon” is touched, the display on the display unit 12 is switched to the volume setting screen shown in FIG. On this volume setting screen, the volume of the swing support notification P can be set to “high”, “medium”, or “small”. When the “return button” is touched after setting, the display on the display unit 12 returns to the execution screen of FIG.

<< Correlation between measurement results, tempo, and time signature >>
When the head speed, the ball speed, the meet rate, and the estimated flight distance are measured and calculated in the “swing mode” while executing the “metronome function” described above, the microcontroller 21 determines these measurement results and calculation results. The tempo and the set value of the time signature of the swing support notification P output at the time of measurement are associated with each other and stored in the memory card 26. Then, the microcontroller 21 causes the display unit 12 to display the correlation between each measurement result and the tempo and time signature of the swing in the manner shown in FIGS. 9A and 9B.

  FIG. 9A is a history display showing the correlation between each measurement result and the tempo and time signature of the swing as numerical values. In this history display, in the order from the left column, the measurement “number of times”, the measurement result of “head speed (m / s)”, the measurement result of “ball speed (m / s)”, and the calculation result of “meet rate” The calculation result of “estimated flight distance (yard)”, the set value of “tempo (BPM)” at the time of measurement, and the set value of “time signature” at the time of measurement are displayed in association with each other. The user can find the most suitable tempo by referring to the history display.

  Further, the correlation between each measurement result and the tempo of the swing is displayed in a graph for each measurement item such as the head speed. For example, FIG. 9B is a graph showing the correlation between the calculation result of the estimated flight distance and the tempo of the swing. The graph of FIG. 9B visually shows that the estimated flight distance has been extended from tempo 50 to 80 BPM, and the estimated flight distance has remained unchanged around 220 yards from the point where it exceeds 80 BPM. By referring to such a graph, the user can give an eye that the most suitable tempo is around 80 BPM.

<< Swing tempo deviation judgment function >>
A function of determining whether or not there is a difference between the tempo of the swing support notification P and the actual swing tempo can be added to the golf support apparatus 1 described above. Hereinafter, the flow of swing tempo deviation determination control executed by the microcontroller 21 will be described with reference to the flowchart shown in FIG.

  In order to add the swing tempo deviation determination function described below, it is not sufficient for the microcontroller 21 to transmit only the tempo, time signature, and volume setting information of the swing support notification P to the wireless earphone 30; The output timing of each unit notification P1, P2 forming the support notification P must be configured to be monitored. For example, a configuration in which the microcontroller 21 generates an audio signal that is the basis of the swing support notification P and transmits it to the wireless earphone 30, or the CPU 35 of the wireless earphone 30 generates an audio signal that is the source of the swing support notification P. A configuration in which the output timing of the audio signal is transmitted to the microcontroller 21 is conceivable.

  In step S <b> 1 of FIG. 10, first, the microcontroller 21 determines whether or not “swing mode” has been selected. When it is determined that “swing mode” is not selected (NO), the control process of this flowchart is terminated. This is because the tempo deviation determination function is associated with the “metronome function”, and the “metronome function” is not executed unless the “swing mode” is selected.

  On the other hand, if it is determined in step S1 that “swing mode” has been selected (YES), the process proceeds to step S2, and the microcontroller 21 determines whether or not the “metronome function” has been selected. If it is determined that the “metronome function” is not selected (NO), the control process of this flowchart is terminated. This is because if the “metronome function” is not selected, the swing support notification P that is a criterion for determining the tempo shift is not output, and it is impossible to determine the presence or absence of the shift.

  On the other hand, if it is determined in step S2 that the “metronome function” has been selected (YES), the process proceeds to step S3, where it is determined whether or not a time signature X within the range of 2 to 6 time signatures has been set. When it is determined that the time signature X is not set (NO), the control process of this flowchart is terminated. If the user is out of the range of 2 to 6 beats, that is, if the user has set no beat, the unit notification output timing corresponding to the last beat constituting the beat cannot be specified, so it is not possible to determine whether there is a tempo shift. is there.

  On the other hand, if it is determined in step S3 that the time signature X within the range of 2 to 6 time signatures has been set (YES), the process proceeds to step S4, and it is determined whether or not the swing support notification is started. When it is determined that the swing support notification is not started (NO), the determination in step S4 is repeated. On the other hand, if it is determined that the swing support notification is started (YES), the process proceeds to step S5, and the microcontroller 21 monitors the output timing of the unit notification.

  Next, the process proceeds to step S6, and the microcontroller 21 determines whether or not the maximum value of the head speed has been measured. If it is determined that the maximum value of the head speed is not measured (NO), the determination in step S6 is repeated. On the other hand, if it is determined that the maximum value of the head speed has been measured (YES), the process proceeds to step S7, and the measurement timing t1 of the maximum value of the head speed is detected. Thereafter, the process proceeds to step S8, and the microcontroller 21 detects the unit notification output timing t2 of the last X beat of the time signature X (the third beat if ex. 3 time) closest to the measurement timing t1. Then, the microcontroller 21 calculates a timing difference tn between the measurement timing t1 and the unit notification output timing t2 of the Xth beat (step S9).

  Next, the process proceeds to step S10, and the microcontroller 21 determines whether or not the timing deviation is tn≈0. Here, if the presence / absence of deviation is strictly determined with “tn = 0”, in most cases, it is determined that there is a deviation. Therefore, in step S10, the timing is determined with “tn≈0” including an error within an allowable range. The presence / absence of tint tn is determined. If it is determined that the timing deviation is tn≈0 (YES), the process proceeds to step S11, and the microcontroller 21 causes the three-color LED 23 to emit “blue” to indicate that “the tempo of the swing is correct”. Inform the user. Then, the control process of this flowchart is complete | finished.

  On the other hand, if it is determined in step S10 that the timing deviation is not tn≈0 (NO), the process proceeds to step S12, and it is determined whether or not the timing deviation is tn <0. If it is determined that the timing difference is tn <0 (YES), the process proceeds to step S13, and the microcontroller 21 causes the three-color LED 23 to emit “yellow” to inform the user that “the tempo of the swing is fast”. Inform. Then, the control process of this flowchart is complete | finished.

  On the other hand, if it is determined in step S12 that the timing difference is not tn <0 (NO), the process proceeds to step S14, where the microcontroller 21 causes the three-color LED 23 to emit “red” and “swing tempo is slow. To the user. Then, the control process of this flowchart is complete | finished.

  According to the above configuration, the difference between the time signature X of the swing support notification P selected by the user and the time signature of the swing performed by the user can be detected, and whether the tempo of the swing is correct, is it fast, or is it slow? Can be notified by the emission color of the three-color LED 23. As a result, the user can efficiently correct the tempo of the swing after grasping whether the tempo of the swing is correct, fast or slow.

  That is, the conventional metronome device does not determine whether the tempo of the swing performed by the user is deviated. For this reason, the user has practiced memorizing the tempo provided by the metronome device with his / her body without knowing whether or not the tempo of his / her swing has shifted. On the other hand, according to the swing tempo deviation determination function in the present embodiment, the tempo when the three-color LED 23 emits “blue” is learned by the body. In this practice, if the three-color LED 23 emits “yellow”, the swing tempo is corrected to be slightly slower, and if the three-color LED 23 emits “red”, the swing tempo is slightly increased. to correct. As a result, the user can efficiently correct the tempo of the swing after grasping whether the tempo of the swing is correct, fast or slow.

<Pass / fail judgment function>
“Pass / fail judgment function” is a function that is executed together with the above-mentioned “swing mode” and “practice mode”, and performs pass / fail judgments such as measurement results of head speed, ball speed, meet rate and estimated flight distance, etc. The evaluation result is notified by the emission color of the three-color LED 23. Hereinafter, the “good / bad determination function” executed by the golf support apparatus 1 will be described in detail with reference to FIGS.

<< Various settings of pass / fail judgment function >>
First, various setting screens and operation procedures when executing the “good / bad determination function” of the golf support apparatus 1 will be described with reference to FIGS. 11 (a) and 11 (b).

  When a “setting icon” is touched on the menu screen of the display unit 12 shown in FIG. 8A, a setting screen (not shown) is displayed. When “PASS / FAIL Judgment Function” is selected from the setting items on this setting screen, the display on the display unit 12 is switched to the “GOOD / FAIL Judgment Function” setting screen shown in FIG. On the setting screen of this “good / bad determination function”, there are five setting items of “good / bad determination function”, “application mode”, “determination item”, and “reference data selection”, and an “OK button” for ending the setting. It is included.

  This “pass / fail judgment function” setting screen is not always displayed in the state shown in FIG. 11A, but the “ON / OFF icon” of the “pass / fail judgment function” located at the top is turned on. When set to “”, the setting items of “application mode”, “judgment item” and “reference data selection” are displayed in the space below, and these setting items can be set. On the contrary, when the “ON / OFF icon” of the “good / bad determination function” is set to OFF, the setting items of “application mode”, “determination item”, and “reference data selection” are not displayed, and FIG. On the setting screen shown in (2), only the setting items of “good / bad determination function”, “ON / OFF icon”, and “OK button” are displayed.

  In FIG. 11A, the “ON / OFF icon” described above is provided in the setting item of “OK / OFF determination function”, and the “ON / OFF icon” is operated by sliding the “ON / OFF icon”. Can be switched on / off. When the “ON / OFF icon” is turned off, the “good / bad determination function” is not executed.

  The “applied mode” setting item includes a “swing mode icon” and a “practice mode icon”, and the “good / bad determination function” is executed for the function mode selected from these icons. Any of these icons can be selected / released by a touch operation. The selected icon is a brightly lit drawing, and the released icon is a darkly unlit drawing. In addition, both of these icons cannot be canceled, and at least one of the icons is selected.

  The “applied item” setting item includes a “head speed icon”, a “ball speed icon”, a “meet rate icon”, and an “estimated flight distance icon”. For the measurement item selected from these icons, A pass / fail judgment function is executed. Similarly to the above, selection / cancellation of an icon can be performed by a touch operation. The selected icon is a brightly lit drawing, and the released icon is a darkly unlit drawing. Further, it is not possible to cancel the selection of all icons, and at least one icon is selected.

<< Selection of reference data >>
In the setting item of “reference data selection” shown in FIG. 11A, “HARD icon”, “NORMAL icon”, “EASY icon”, and “OPTION icon” are provided. In the “reference data selection” setting item, reference data for performing pass / fail judgments such as measurement results of the head speed, ball speed, meat rate, and estimated flight distance are selected.

  Here, in the present embodiment, first to third reference data (see FIG. 13) having different degrees of difficulty, in which a predetermined threshold is set in advance, are prepared, and each of the first to third reference data is “HARD icon”. ”,“ NORMAL icon ”, and“ EASY icon ”. When the “HARD icon” is selected, the quality determination of the measurement result and the like is performed using the first reference data having a high degree of difficulty. In addition, when the “NORMAL icon” is selected, the pass / fail determination of the measurement result or the like is performed using the second reference data having an intermediate difficulty level. Further, when the “EASY icon” is selected, the quality determination of the measurement result and the like is performed using the third reference data with a low difficulty level. The user may select “HARD icon”, “NORMAL icon”, or “EASY icon” according to his / her golf ability.

<< Threshold setting for reference data >>
On the other hand, when the “OPTION icon” is selected in the “reference data selection” setting item, the user can arbitrarily set the threshold value of the reference data. When the “OPTION icon” shown in FIG. 11A is selected by a touch operation, the screen display of the display unit 12 is switched to a reference data setting screen as shown in FIG. This reference data setting screen includes “head speed”, “ball speed”, “meet rate”, and “estimated flight distance” setting items. For each of these setting items, a “first threshold icon”, A “second threshold icon” and a “third threshold icon” are provided. Thus, in this embodiment, it is possible to set the first to third threshold values for each setting item such as the ball speed.

  When one of the “first threshold icon”, “second threshold icon”, and “third threshold icon” of each setting item shown in FIG. 11B is touch-operated, the screen display of the display unit 12 is changed to FIG. The screen is switched to a threshold value input screen for reference data as shown in c) to (f). FIG. 4C shows the head speed, FIG. 4D shows the ball speed, FIG. 6E shows the meet rate, and FIG. 8F shows the estimated distance input screen.

  On such a threshold value input screen, a threshold value within a predetermined numerical range is input by touching a keyboard of “0” to “9”. The input threshold value can be converted into a metric system or a pound yard system by touching the “unit button”. For example, the head speed threshold “49.0” and the ball speed threshold “72.7” shown in FIGS. 11C and 11D are both numerical values in the metric speed unit [m / s]. The “unit button” can be touched and converted into a numerical value in the speed unit [mph] of the pound yard method. The threshold value “260.0” of the estimated flight distance shown in FIG. 5F is a numerical value in the distance unit [yard] of the pound yard method, but by touching the “unit button”, the metric distance unit. It can be converted into a numerical value in [m]. There is no unit in the meet rate shown in FIG.

<< Specific examples of reference data >>
Next, a specific example of reference data used for the “good / bad determination function” will be described with reference to FIGS. 12 and 13.

  FIG. 12 is a table showing a specific example of one reference data. The table includes columns of “measurement item”, “LED emission color”, “settable range”, and “reference data (initial value)” in order from the left side. The measurement items for which pass / fail judgment is performed by the “pass / fail judgment function” are “head speed”, “ball speed”, “estimated flight distance”, and “meet rate”, and the evaluation results of pass / fail judgment for each measurement item are three. The color LED 23 is notified by the light emission color of “blue”, “yellow”, or “red”.

  In this embodiment, for each measurement item such as the head speed, reference data shown in the column of “reference data (initial value)” is provided, and the reference data of each measurement item is “blue” of the three-color LED 23, It consists of three threshold values (six threshold values including the unit conversion) corresponding to the emission colors of “yellow” and “red”. The threshold value of each measurement item shown in the column “reference data (initial value)” in FIG. 12 is an example. In each measurement item, the threshold value corresponding to the emission color of “blue” is set to the highest. The threshold value corresponding to the “yellow” emission color is high, and the threshold value corresponding to the “red” emission color is set to the lowest. That is, the evaluation result of the pass / fail judgment is high in the order of “blue”, “yellow”, and “red”.

  In addition, the initial value of the threshold value actually provided to the user can be set to a value referring to the average value of professional golfers and amateur golfers, for example. However, if the threshold is set too high, it is difficult to obtain an evaluation result of “blue” or “yellow”, and the fun of the “good / bad determination function” is reduced. On the other hand, if the threshold is set too low, the evaluation result of “blue” occurs frequently, and the fun of the “good / bad determination function” is reduced. Therefore, it is preferable that the initial value of the threshold value actually provided to the user is a value that is not too high and not too low and has an appropriate difficulty level. For this reason, in the present embodiment, an arbitrary threshold value can be set according to the user's preference within the numerical range shown in the “settable range” column of FIG.

  FIG. 13 is a table showing a specific example of a plurality of reference data having different difficulty levels in stages. As shown in the figure, first to third reference data having different difficulty levels with predetermined threshold values set in advance may be provided. In the figure, the threshold value shown in the column of “first reference data (HARD)” is set to the highest value, the threshold value shown in the column of “second reference data (NORMAL)” is next high, and “third reference data” The threshold shown in the column (EASY) is set to the lowest. The user may select either “first reference data (HARD)”, “second reference data (NORMAL)”, or “third reference data (EASY)” according to his / her golf ability.

<< Pass / fail judgment control >>
Hereinafter, the flow of the quality determination control in the “quality determination function” executed by the microcontroller 21 will be described with reference to FIG. FIG. 14 is a flowchart illustrating a flow of pass / fail judgment control of the head speed measurement result as an example.

  In step S21 of FIG. 14, the microcontroller 21 first determines whether or not “swing mode” has been selected. If it is determined that the “swing mode” is not selected (NO), the process proceeds to step S22, and the microcontroller 21 determines whether or not the “practice mode” is selected. When it is determined that “practice mode” is not selected (NO), the control process of this flowchart is terminated. This is because the “pass / fail judgment function” performs the pass / fail judgment of the measurement result in the “swing mode” or the “practice mode”.

  On the other hand, if it is determined in step S21 that “swing mode” has been selected (YES), or if it is determined in step S22 that “practice mode” has been selected (YES), the process proceeds to step S23. The controller 21 determines whether or not the “good / bad determination function” is selected. If it is determined that the “good / bad determination function” is not selected (NO), the control process of this flowchart is terminated.

  On the other hand, if it is determined in step S23 that the “good / bad determination function” is selected (YES), the process proceeds to step S24, and the microcontroller 21 determines whether the maximum value HS of the head speed has been measured. . If it is determined that the maximum value HS of the head speed has not been measured (NO), the determination in step S24 is repeated.

  On the other hand, if it is determined in step S24 that the maximum value HS of the head speed has been measured (YES), the process proceeds to step S25, and the microcontroller 21 determines that the maximum value HS of the head speed is the first threshold value shown in FIG. It is determined whether or not “50 m / s” or higher. If it is determined that the maximum value HS of the head speed is “50 m / s” or more (YES), the process proceeds to step S26, and the microcontroller 21 causes the three-color LED 23 to emit “blue” to measure the head speed. Inform the user that the result was good. Then, the control process of this flowchart is complete | finished.

  On the other hand, if it is determined in step S25 that the maximum head speed value HS is not equal to or greater than "50 m / s" (NO), the process proceeds to step S27, and the microcontroller 21 determines that the maximum head speed value HS is as shown in FIG. It is determined whether or not the second threshold is “40 m / s” or more. When it is determined that the maximum value HS of the head speed is “40 m / s” or more (YES), the process proceeds to step S28, where the microcontroller 21 causes the three-color LED 23 to emit “yellow” and the measurement result of the head speed is obtained. Is notified to the user. Then, the control process of this flowchart is complete | finished.

  On the other hand, if it is determined in step S27 that the maximum value HS of the head speed is not equal to or greater than “40 m / s” (NO), the process proceeds to step S29, and the microcontroller 21 determines that the maximum value HS of the head speed is as shown in FIG. It is determined whether or not the third threshold value “30 m / s” or higher is indicated. When it is determined that the maximum value HS of the head speed is “30 m / s” or more (YES), the process proceeds to step S30, and the microcontroller 21 causes the three-color LED 23 to emit “red” and the measurement result of the head speed. Inform the user that is not so good. Then, the control process of this flowchart is complete | finished.

  On the other hand, if it is determined in step S29 that the maximum value HS of the head speed is not equal to or greater than “30 m / s” (NO), the microcontroller 21 ends the control process of this flowchart without causing the three-color LED 23 to emit light. . In this case, it means that the measurement result of the head speed was bad.

  As described above, the quality determination control of the head speed measurement result has been described as an example. However, the microcontroller 21 executes the control process substantially similar to the above for the measurement result of the ball speed, the meet rate, the estimated flight distance, and the like. The evaluation result of the pass / fail judgment is notified by the emission color of the three-color LED 23.
