Description

  The present invention relates to an apparatus and the like for assisting adjustment of a swing or the like in putting or approach such as golf.

  In recent years, various systems for assisting in playing and practicing golf have been proposed. Among such systems, there is a system that acquires motion data when swinging a golf club and presents swing information based on the motion data to the user. For example, there is a proposal of a trainer system including a swing sensor attached to a golf club shaft in order to detect a swing path or the like (for example, Non-Patent Document 1).

Nihon Bunka Shuppan GolfClassic March 2013 issue (pages 86-91)

  Many conventional systems such as the above system support swing training for the purpose of flying a hitting ball farther, such as putting and approach shots, and adjusting the flight distance according to the target distance No function was provided to help you adjust.

  Therefore, an object of the present invention is to provide, for example, support for swing adjustment in putting and approach shots for golf and the like. This object can be achieved, for example, by a combination of components described in the means for solving the problems. The dependent claims can be, for example, further advantageous specific examples of the present invention.

(1) A mounting member that can be mounted on a part that moves along with a golf swing, a detection unit that changes output according to the amount of takeback in the swing, a notification unit that notifies the user, and a designation by the user The takeback amount corresponding to the specified swing strength is based on the correspondence between the information about the swing strength and the information about the swing strength and the data indicating the takeback amount based on the output of the detection unit. The apparatus may include a control unit that controls the notification unit so that the user is notified of the arrival.

  In this way, the user can be notified when the takeback amount corresponding to the specified swing strength is reached. Therefore, by starting the downswing with the notified takeback amount, the swing can be performed with a stable takeback amount. The swing is preferably a putting or approach, particularly a putting. The feeling of distance of putting is not the strength of how to put force at the time of impact, but it is correct to adjust by swing width. For this reason, the improvement of putting can be supported by notifying that the amount of takeback at the time of putting is stabilized.

  The “information regarding the strength of the swing” may be, for example, the flight distance of the hit ball as described later (3), or a preset value that is associated with the takeback amount as illustrated in (7). Good.

  The “data indicating the takeback amount” may be the data itself output by the detection unit, or may be data obtained by processing the output of the detection unit. For example, in a configuration using an acceleration sensor that detects acceleration as the detection unit as described later (14), the data indicating the takeback amount may be acceleration data based on the acceleration. In this case, the acceleration data may be the acceleration itself detected by the acceleration sensor, but may be data obtained by calculating and processing the acceleration detected by the acceleration sensor, and selecting data that can easily identify the movement during the swing. Especially good.

  The “correspondence relationship between the information on the strength of the swing and the data indicating the takeback amount based on the output of the detection unit” may be stored in advance in the storage unit or the like, but is stored according to the registration operation by the user. This is especially good. Further, there may be a one-to-one correspondence between each piece of “information about swing strength” and “data indicating takeback amount”, but a plurality of “information about swing strength” and “takeback amount” are shown. It is particularly preferable to use a function (for example, a mathematical expression) that comprehensively represents the correspondence relationship with “data”.

  The “notification unit” may be anything as long as the user wearing the apparatus can recognize the notification. For example, it may be a buzzer or a speaker that makes an audible notification by voice, or may be a display element or a light emitting element that makes a visual notification by display or light emission. It is particularly good to use a vibrator that provides notification. If it is a notification by vibration, the notification can be made without violating the play manner of golf.

(2) The notification is performed when the data indicating the takeback amount based on the output of the detection unit reaches the target value of the data indicating the takeback amount corresponding to the information related to the specified swing strength. Good.

  The “target value of data indicating the takeback amount” may be determined by any method. For example, the data read from the storage unit or the like may be used as the target value as it is, but it is particularly preferable that the target value is obtained by calculation.

(3) Information regarding the strength of the swing specified by the user may be the hit distance of the hit ball. The flight distance may be specified in units of stride length or club length, and particularly preferably in stride length units. By using the stride and club length, which are distance measuring means that are allowed during golf play, it becomes easy to use the apparatus during play.

  In this way, the user can be notified of a takeback amount suitable for hitting a specified distance or putting a shot. For example, if there are 4 steps from the current position of the ball to the cup, a notification to that effect can be received when the takeback amount suitable for the flight distance of the 4 steps is reached, so a downswing can be started from there. it can. As a result, the ball can be hit with the strength of four steps.

(4) The correspondence relationship between the information about the strength of the swing and the data indicating the takeback amount based on the output of the detection unit may be a function that defines the relationship between the flight distance of the hit ball and the data indicating the takeback amount, For example, the control unit may obtain a target value corresponding to the flight distance designated by the user based on a function stored in the storage unit or the like.

  In this way, it is possible to store the correspondence between the hit distance and the data indicating the takeback amount with a small capacity. Further, the target value can be calculated based on the function regardless of the flight distance.

(5) The control unit stores the flight distance and the data indicating the takeback amount in association with each other for a plurality of swings, and stores the function based on the correspondence between the multiple sets of the flight distance and the data indicating the takeback amount. It is good to estimate.

  In this way, based on the user's own swing in which the correspondence is recorded, a function that defines the correspondence between the hit distance and the data indicating the takeback amount can be obtained. Therefore, the user can be notified of the takeback amount for hitting the ball at the intended flight distance with higher accuracy.

(6) The control unit prompts the user to perform a swing, records data indicating a takeback amount in the swing, prompts the user to input a flight distance of the hit ball by the swing, and records the input flight distance The data indicating the takeback amount may be stored in association with each other.

  In this way, the correspondence between the takeback amount and the flight distance of the hit ball can be defined based on the user's own swing. In addition, the relationship between takeback amount and flight distance can change depending on the physical condition of the day of play and the condition of the golf course. If the relationship between takeback amount and flight distance is registered before the start of play, it is suitable for the condition of the day. Notification can be received based on the relationship between the takeback amount and the flight distance.

(7) The information related to the strength of the swing specified by the user may be a preset value that is associated with the takeback amount.

  In this way, it is possible to specify a setting value related to the takeback amount that determines the strength of the swing, and receive a notification according to the specification. In particular, the level of putting is not adjusted by the amount of force at the time of impact, but is adjusted by the swing width of the swing, so it is possible to receive notification by quantifying the amount of takeback that determines the swing width of the swing. This configuration contributes to improvement of the putting technique.

(8) A display unit may be further provided, and the display unit may display the set value and the flight distance in association with each other.

  In this way, the user can recognize the flight distance according to the set value. The displayed distance is preferably in units of stride length or club length, and particularly preferably in terms of stride length. By using the stride and club length, which are distance measuring means allowed during golf play, the display can be used without hindering play.

(9) The display unit may display so that a plurality of sets of setting values and flight distances can be compared.

  “To be compared” means, for example, that a plurality of sets of set values and flight distances are displayed in a list. In this way, the abnormal value of the displayed data can be estimated. In addition, when the flight distance data corresponding to a certain setting value is registered with the data of the previous play and when attempting to update the flight distance data, a notification is received with one setting value and the ball is By comparing the flight distance at the time of hitting with the flight distance at the previous registration, it is possible to easily grasp the tendency of the flight distance in the condition of the day. In addition, if the flight distance was the same as the previous registration, it can be assumed that the flight distances corresponding to the other setting values displayed in the list are the same as the previous one. It can be simplified.

(10) The flight distance corresponding to the set value may be configured to be changeable by the user. For example, the user designates a set value, performs takeback until a notification is received, starts a downswing from the notified takeback amount, and performs association by registering the flight distance of the hit ball at that time Good.

  In this way, the correspondence between the set value and the flight distance can be defined based on the user's own swing. In addition, the relationship between the takeback amount and the flight distance can change depending on the physical condition of the day of play and the condition of the golf course. If you register the relationship between the setting value and the flight distance before the start of play, it will Therefore, it is possible to display a guide of the flight distance corresponding to the set value, and to easily select a set value that matches the intended flight distance.

(11) The control unit detects the inclination of the place where the user is present, and when detecting the inclination rising in the direction of travel of the hit ball, the takeback amount is larger than the takeback amount notified at the position where there is no inclination Notification is made when reaching the position, and notification is made when the takeback amount that is smaller than the takeback amount notified at a position where there is no inclination is detected when it is detected to move down in the traveling direction of the hit ball. It is good to control the part. The control unit may detect the inclination based on the output of the detection unit.

  In this way, it is possible to notify a large takeback amount so that a strong swing is obtained on the uphill slope, and a small takeback amount so as to provide a weak swing on the downhill slope. As a result, the user can perform the swing with the takeback amount adjusted based on the inclination by starting the downswing with the notified takeback amount. And it becomes easy to obtain the target flight distance with a sense of distance equivalent to that when it is a flat place, and it is possible to improve the number of hits of the putt.

(12) The control unit may control the notification unit so as to increase a difference between a takeback amount notified at a location where the user is present and a takeback amount notified at a position without the tilt, as the detected inclination is larger. .

  In this way, a larger takeback amount is notified so that the stronger the swing is, the steeper upward slope, and a smaller takeback amount is notified, so that the swing is weaker, the steeper downward slope. can do. As a result, the user can perform the swing with the takeback amount based on the inclination by starting the downswing with the notified takeback amount, and can easily perform the swing with the adjustment in accordance with the desired hitting distance. Therefore, it is possible to improve the number of hits of the putt.

(13) In the above (11) or (12), the detection of the tilt may be performed at the timing when the address is detected.

  In this way, it is possible to detect the inclination at the position where the swing is about to be performed, and it is possible to notify with the takeback amount corresponding to the inclination at the position.

(14) The detection unit may be an acceleration sensor that detects the acceleration sensor, and the data indicating the takeback amount may be acceleration data based on the acceleration. For example, the acceleration sensor may output data indicating acceleration as triaxial acceleration. Although the acceleration data may be the acceleration itself detected by the acceleration sensor, the acceleration data may be data obtained by calculating and processing the acceleration detected by the acceleration sensor, and it is particularly preferable to select data that can easily identify the movement during the swing.

(15) A storage unit that stores acceleration data when the user takes an address posture is further provided, and the control unit receives acceleration data based on the output of the acceleration sensor and the user stored in the storage unit takes an address posture. Based on the acceleration data, it is preferable to detect that the user has taken an address posture and perform control to notify the user that the address posture has been detected.

  In this way, the user can confirm that he / she has taken the same address posture as when he / she registered acceleration data at the time of address. If the user registers in advance when the correct address posture is obtained, the user can be notified when the correct address posture is obtained. The way the club is held, the address posture, and the relationship between the body and the club vary from person to person, but are almost constant for the same person. In the configuration in which the device is worn on the wrist as in the configuration (18) described later, the user can take the same address posture as at the time of registration including not only the club angle but also the grip and grip state. Is particularly good. Further, the takeback amount can be obtained based on the acceleration data at the time of address and the acceleration data at the time of takeback based on the acceleration data.

(16) In the configuration of (15), the control unit determines the difference between the acceleration data when the user has detected the address posture and the acceleration data stored in the storage unit when the user has the address posture. Based on the above, if the inclination is detected, and the inclination rising in the direction of hitting the ball is detected, the notification is made when the takeback amount reaches a larger amount than the takeback amount notified at the position where there is no inclination. When it is detected to move downward in the traveling direction, the notification unit may be controlled so that a notification is made when a takeback amount that is smaller than a takeback amount notified at a position with no inclination is reached.

  In this way, it is possible to detect the inclination of the place where the user is going to swing. Then, it is possible to notify a large takeback amount so as to make a stronger swing on the uphill slope, and notify a small takeback amount so as to make a weaker swing on the downhill slope. As a result, the user can perform the swing with the takeback amount adjusted based on the inclination by starting the downswing with the notified takeback amount. And it becomes easy to obtain the target flight distance with a sense of distance equivalent to that when it is a flat place, and it is possible to improve the number of hits of the putt.

(17) In the data indicating the takeback amount, at least one of the magnitude of the acceleration component in the back direction of the user and the magnitude of the acceleration component in the vertical direction is weighted differently from the magnitude of the acceleration component in the hitting direction. A value obtained by addition is good. The weight of each component may be determined so that the sensitivity for various swings is comparable.

  In this way, it is possible to take a swing with various characteristics such as a swing of the trajectory along the hitting direction when viewed from the user, a swing of a trajectory with an arc that attracts the club to the body at the time of takeback and follow swing, etc. The back amount can be obtained. The user can use the device without worrying about the type of swing.

(18) The “part moving along with the golf swing” mounted by the mounting member may be a golf club, but may be a part of the user's body and particularly a wrist. In this way, the movement of the user's wrist during the swing can be detected by the acceleration sensor, and the movement during the swing can be easily discriminated. In particular, in the configuration in which the address posture is detected and notified as in (11), it is possible to notify that the user-specific address posture is correctly taken.

(19) The notification unit may be a vibrator that notifies the user by vibration. In this way, it is possible to notify the user without obstructing play while protecting the manners of golf.

(20) In the program of the present invention, the computer may function as the device described in any one of (1) to (19).

[First Embodiment]
1 and 2 are perspective views showing the external appearance of the apparatus 10. FIG. 3 is a schematic diagram showing a state in which the user U is wearing the wrist 10 along with the axial direction of the acceleration sensor 112. FIG. 4 is a block diagram illustrating the configuration of the apparatus 10. The device 10 is assumed to be worn on the left wrist of the user U. As shown in FIGS. 1 and 2, the device 10 has an appearance similar to a wristwatch, and includes a flat case 110 and a band 120 that holds the case and is fixed to the wrist of the user U. The band 120 is generated from a flexible material such as urethane or silicone rubber. The band 120 includes a jacket part 121 and two belts 122 a and 122 b extending from both ends of the jacket part 121. The jacket portion 121 is provided with openings for exposing the front and back surfaces of the case 110 and the tact switch 150. A groove is provided in the opening of the jacket portion 121, and the case 110 is fitted and held in the groove. A plurality of small holes 123 (see FIG. 1) are formed in the belt 122a along the longitudinal direction. A fastener 130 for fastening the belt 122b to the belt 122a is joined to the tip of the belt 122b.

  The fastener 130 is made of a metal such as stainless steel. The fastener 130 includes a buckle 131, an intermediate plate 133, and a lower plate 135. The middle plate 133 and the lower plate 135 are curved so as to generally follow the wrist when the band 120 is attached to a human wrist. The buckle 131 and the intermediate plate 133 are connected by passing a shaft rod through a bearing portion 132 projecting from the back surface of the buckle 131 and a through hole 133 a formed at one end of the intermediate plate 133. Further, the intermediate plate 133 and the lower plate 135 are connected by passing a shaft rod through a through hole 133 b formed at the other end of the intermediate plate 133 and a through hole 135 a formed at one end of the lower plate 135. . At the other end of the lower plate 135, a guide portion 135b for guiding the belt 122a along the concave surface side of the lower plate 135 is provided.

  On the concave surface side of the lower plate 135, a positioning projection 135c is projected. The lower plate 135 is coupled to the belt 122a by passing the belt 122a through the guide portion 135b and passing the positioning projection 135c through one of the small holes 123 of the belt 122a. The small hole 123 through which the positioning protrusion 135c is passed may be appropriately selected according to the thickness of the wrist of the user who uses the apparatus 10.

  A locking projection 135d protrudes from the convex surface near the end of the lower plate 135 where the guide portion 135b is provided. The locking projection 135d has a hook-shaped tip, and when the buckle 131, the middle plate 133, and the lower plate 135 are folded, the latching projection 135d is locked to the notch 133c of the middle plate 133 and maintains the folded state. Acts as follows. With such a configuration, the ring formed by the belt (122a, 122b) and the fastener 130 can be expanded and contracted. The user U puts the device 10 on the wrist as shown in FIG. 3 by passing the hand through the ring with the clasp 130 opened (that is, with the ring expanded) and then closing the clasp.

  A display unit 170 is provided in front of the case 110. The display unit 170 includes a small liquid crystal panel, and displays various information such as an operation mode, a remaining battery level, and a clock display under the control of the control unit 115 described later.

  On the lower side of the display unit 170 on the front surface of the case 110, a symbol indicating the return button 141 and the home button 142 is drawn. A touch panel 140 that detects an operation caused by contact with the front surface of the case 110 is provided so as to overlap the patterns of the display unit 170 and the return button 141 and the home button 142. The touch panel 140 detects a press operation and a so-called swipe operation that moves the contact position while touching the surface of the touch panel 140. The operation detected by the touch panel 140 is sent to the control unit 115. The control unit 115 executes processing according to the operation on the touch panel 140. For example, when the touch panel 140 detects a pressing operation of the back button 141 to the position where the symbol is drawn, the control unit 115 recognizes this operation as pressing the back button, and performs control such as returning to the previous state. A tact switch 150 is provided on the left side surface of the case 110 (not shown in FIG. 1). The tact switch 150 is a push button switch used for power ON / OFF, selection item selection, and the like. Operations according to operations of the touch panel 140 and the tact switch 150 will be described later. The tact switch 150 can be provided on the right side of the case 110. However, if the tact switch is on the right side, the tact switch 150 may be erroneously pressed due to the movement of returning the wrist when the device 10 is mounted on the left hand. There is. By providing the tact switch 150 on the left side surface of the case 110, it is possible to prevent an erroneous operation associated with the movement of returning the wrist. When the tact switch 150 is held by the jacket portion 121 and not pressed down, the top of the head 120 does not protrude from the jacket portion 121 of the band 120. A tact switch 150 is provided so that it can be pressed. If it does in this way, it can control that tact switch 150 is pushed accidentally by unintentional contact.

  A plastic back cover 118 is attached to the back of the case 110 by screwing four corners with screws 118a. The thickness from the front surface of the case 110 to the back cover 118 is configured to be thicker than the thickness of the jacket portion 121, and the case 110 is held by the jacket portion 121 so that the front surface thereof is substantially level with the outer surface of the jacket portion 121. The Therefore, in the state where the case 110 is held by the jacket part 121, the back cover 118 protrudes from the jacket part. By forming the back cover 118 so as to protrude from the jacket portion 121 in this way, it is possible to make an illusion that the thickness of the jacket portion 121 is the thickness of the device 10 when the user U wears the device 10. It is possible to prevent the person who sees the apparatus in a worn state from feeling the thickness of the apparatus 10 large. A terminal cover 119 is provided at the center of the back cover 118 so as to be openable and closable. When the terminal cover 119 is opened, the miniUSB terminal 160 is exposed. The battery 116 can be charged by connecting an AC adapter to the miniUSB terminal 160. Further, by connecting to an external personal computer or the like via a USB cable, it is possible to update the data of the golf course in the apparatus 10 or import the data into the personal computer from the personal computer.

  As shown in FIG. 4, the case 110 includes a GPS receiver 111 that receives a GPS signal from a GPS satellite and obtains the current position (longitude / latitude), an acceleration sensor 112 that detects acceleration in three axes, and vibration. Vibrator 113 that performs notification, control unit 115 that controls each component in apparatus 10, battery 116 that serves as a power source, program executed by control unit 115, golf information such as course layout of golf course, control unit 115 A storage unit 117 or the like for storing data obtained by various functions under control is provided.

The acceleration sensor 112 outputs acceleration data of three axes orthogonal to each other. The triaxial acceleration data output from the acceleration sensor 112 is acquired by sampling at a sampling frequency (for example, 50 Hz) set by the control unit 115. The three axial directions of the acceleration sensor 112 are orthogonal to each other. By using the triaxial data output from the acceleration sensor 112, it becomes easier to determine the acceleration associated with the swing than in the case of using the uniaxial acceleration sensor. First axis direction (X-axis) is the downward direction of the display surface of the display unit 170, the following acceleration of the axial called G _x. Second axis direction (Y-axis) is the right direction of the display surface of the display unit 170, the following acceleration of the axial called G _y. The third axial direction (Z-axis) is the normal direction of the display surface of the display unit 170, and hereinafter, the acceleration in the axial direction is referred to as _Gz .

  The acceleration sensor 112 outputs the magnitude of the component in the direction of each axis of the acceleration obtained by combining the gravitational acceleration and the acceleration accompanying the motion. At rest, such as when the address posture is taken, the gravitational acceleration vector is decomposed into vectors in the directions of the three axes, and the magnitude of the vector component in each axis direction is output. In a non-stationary state such as when swinging, acceleration data obtained by synthesizing gravitational acceleration and acceleration due to takeback motion is output.

  FIG. 3 shows a state in which the device U is worn by the user U. The device 10 is mounted such that the back cover 118 of the case 110 is along the back side of the user's U left wrist. As a result, the device 10 generally has a direction in which the X axis is from the little finger of the left hand of the user U to the thumb, a Y axis is from the elbow to the fingertip along the forearm of the user U, and a Z axis is of the left wrist of the user U. It is fixed to the left wrist of the user U in a direction substantially perpendicular to the back side.

  Vibrator 113 vibrates in accordance with control by control unit 115 and notifies the user wearing apparatus 10.

  The battery 116 is a rechargeable secondary battery such as a rechargeable battery, and can be charged from the miniUSB terminal 160.

  The storage unit 117 may be an internal storage device that cannot be detached, or may be a slot unit (including a read / write function) for mounting a removable recording medium such as a micro SD card slot. In this example, the storage unit 117 is described as an internal storage device. Specifically, a nonvolatile memory is used as the storage unit 117. The storage unit 117 is a program that regulates the control by the control unit 115, data used in the program, data on the location and course of the golf course (for example, course layout of each hole, golf course green, bunker, etc. Golf course information including the position) is stored. The golf course information is, for example, information on layout images from the first hole to the 18th hole described in JP-A-7-57189, latitude and longitude data on the layout image, and JP-A-2003-57189. The data relating to the layout, location, course characteristics, etc. of each hole of the golf course described in Japanese Patent No. 339929 can be used.

  The control unit 115 includes a CPU, various peripheral circuits, and the like. When the CPU executes a program stored in the storage unit 117, the various input devices (the GPS receiver 111, the acceleration sensor 112, the touch panel 140, The information input from the tact switch 150, the miniUSB terminal 160, etc.) and the data stored in the storage unit 117 are appropriately used to control the output device (the display unit 170, the storage unit 117, the miniUSB terminal 160, etc.) , Save the processing results.

  The apparatus 10 has two operation modes: a golf course guidance mode and a green mode. The golf course guidance mode is a mode used when playing on a golf course, and automatically records play information such as a score and a hitting ball position. The green mode is a mode in which the user U is notified according to the takeback amount when putting. These operation modes can be switched by operating the touch panel 140 or the tact switch 150.

  Hereinafter, the control executed by the control unit 115 with respect to the operation of the apparatus 10 will be described. Note that the processing in which the subject is not specified in the following description is based on the control of the control unit 115.

  The user U needs to charge the battery 116 in advance before use. When the control unit 115 recognizes that the tact switch 150 has been pressed and held for 2 seconds or more in a state where the battery 116 is sufficiently charged and the power is off, power is supplied to each unit connected to the control unit 115. Control is performed, and the home screen shown in FIG. The home screen includes a main course button B1 for selecting the golf course guidance mode and a green button B2 for selecting the green mode. When it is recognized that the home button 142 is touched when operating in each operation mode or during various settings, the home screen is displayed again. When the control unit 115 recognizes that the tact switch 150 has been pressed for 5 seconds or more in the power-on state, the control unit 115 draws a predetermined end screen on the display unit 170 and is connected to the control unit 115. Control to turn off the power to each part.

  After the power is turned on, various menus are displayed on the display unit 170 so as to accept an operation by the user U under the control of the control unit 115. As an operation method for selecting a menu, for a menu displayed as a button on the screen of the display unit 170, a menu corresponding to the displayed button is selected by pressing the button. In addition, as an operation for selecting and determining a menu displayed on the display unit 170 as a list of a large number of selection items that do not fit within one screen, the items to be selected are changed by scrolling the items displayed by the swipe operation of the touch panel 140. Then, when the tact switch 150 is pressed shortly, the selected item is determined. At this time, if a display area sufficient to display a menu of three items can be secured on the screen, the three items are displayed side by side in three rows, and the center item is set as the selected item. The selected center item is displayed with its color reversed from the upper and lower two items so that the user can easily recognize that the item is selected. When the top item is selected, nothing is displayed on the uppermost line. Conversely, when the lowermost item is selected, nothing is displayed on the lowermost line. When the display area that can be secured is small, only one selected item is displayed, and another item is selected by a swipe operation up and down or left and right.

(Golf course guidance mode)
When the golf course guidance mode is selected by pressing the course button B1 on the home screen shown in FIG. 5A, the operation mode is switched to the golf course guidance mode. In the golf course guidance mode, the GPS receiver 111 is operated to execute a golf course navigation function. When the golf course guidance mode is selected, the golf course selection screen shown in FIG. 5B is displayed. On the golf course selection screen, the golf course closest to the current location acquired by the GPS receiver 111 (in this example, Tokyo International GC) is automatically displayed as a golf course candidate to be selected. It is also possible to search and select a golf course by manual search. The user U operates the touch panel 140 and the tact switch 150 to determine the OUT / IN of the golf course and golf course to play.

  When the selection of the golf course is completed, the navigation screen shown in FIG. 5C is displayed on the display unit 170 and guidance is started. On the navigation screen, the hole number of the current hole, the number of par shots, the current number of shots, the distance to the object (green edge, cup, hazard, etc.) are displayed. The hole is determined based on the position information acquired by the GPS receiver 111 and the golf course information. Specifically, the present location latitude and longitude acquired by the GPS receiver 111 is referred to course map data in which the course layout of the golf course is associated with latitude and longitude, and the current hole is determined. The user U can check the information and score of the hole being played by looking at the navigation screen. The control unit 115 periodically acquires position information from the GPS receiver 111 and updates display information on the navigation screen according to the acquired position information. When it is recognized that the tact switch 150 is pressed while the navigation screen is displayed in the golf course guidance mode, the number of hits is incremented by one and the position information output from the GPS receiver 111 is associated with the number of hits as the hitting position. The point registration to be recorded in the storage unit 117 is performed.

(Green mode)
When the green mode is selected by pressing the green button B2 on the home screen shown in FIG. 5A, the operation mode is switched to the green mode. In addition, when the touch screen 140 is pressed for 2 seconds or longer while the navigation screen in the golf course guidance mode is displayed, the switching screen shown in FIG. 5D is displayed. The switching screen includes a green button B3 for switching to the green mode and a next hole button B4 for manually switching the navigation hole to the next hole. When the touch to the green button is recognized, the operation mode is set to the green mode. Switch. When using the green mode other than during the round (for example, at home or practice field), it is convenient to switch to the green mode from the home screen, and while using the golf course guidance mode during the round, the green mode When using, it is convenient to switch to the green mode via the switching screen.

  When the green mode is entered, first, the green mode menu screen shown in FIG. 6A is displayed. On the green mode menu screen, an address registration menu, a putter registration menu, a putter practice menu, and a registration data deletion menu are displayed so as to be selectable by a swipe operation on the touch panel 140. In FIG. 6A, the registration deletion menu is outside the screen. Touching the return button 141 while the green mode menu screen is displayed ends the green mode and returns to the previous screen (the home screen or the switching screen depending on the operation when the mode is switched to the green mode).

  The address registration menu is a menu for executing an address registration function for registering output data of the acceleration sensor 112 when the user U takes an address attitude (hereinafter simply referred to as address registration). When the address registration is not performed, the putter registration menu, the putter practice menu, and the registration data deletion menu cannot be selected.

  In the address registration menu, the acceleration data at the address that is a reference for measuring the takeback amount is registered. By performing address registration with the device 10 mounted on the wrist as in the present embodiment, acceleration data corresponding to the address posture of the individual user U who performs address registration can be registered. As will be described later, when the takeback amount is measured, the user is notified when it is recognized that the address posture has been taken because acceleration data close to the acceleration data registered in the address registration is maintained for a predetermined time. Therefore, by registering the correct address posture for the user U, the user U can start swinging after confirming that the correct address posture is taken.

When the tact switch 150 is pressed while the address registration menu is selected, the address registration screen shown in FIG. 6B is displayed to prompt the user U to take an address posture and the tact switch 150 is pressed. The user U waits for an address posture for a predetermined standby time. Then, the variation of the output data of the acceleration sensor 112 continues for a predetermined determination time (for example, 2 seconds) for all three axes within a predetermined range (for example, 0.1 G (where G means gravitational acceleration, 1.0 G = 9. (Corresponding to 80665 m / s ² ))) If it falls within the following, it is recognized that the address posture has been taken, the vibrator 113 is vibrated to notify the user that the address has been detected, and the output data of the acceleration sensor 112 varies. The average value of the output data of the acceleration sensor 112 (for example, 100 values in the case of sampling at 50 Hz for 2 seconds) at the determination time within which the three axes are within the predetermined range is stored in the storage unit 117 for each of the three axes. Further, the display unit 170 displays that the address has been registered for 1 second, and then returns to the address registration screen.

  The determination time for determining that the address posture has been taken may be 2 seconds. The inventors have found that the device 10 is stationary for about 2 seconds at the time of addressing, and since this time is set to a time when the user U does not have to rest, the address attitude has been taken. Suitable for detection. The standby time after pressing the tact switch is preferably 10 seconds. If the user U is not familiar with the operation of the device 10 or if the user U cares about the grip, it takes about 5 seconds to hold the club after pressing the tact switch, and then secures a rest time of 2 seconds. There is a need to. By setting the standby time to 10 seconds, it is possible to proceed to the next process without causing discomfort to the user U when an address cannot be detected while securing a sufficient time for taking an address posture.

  On the address registration screen after the address registration is completed, in addition to the address registration menu, a putter registration menu, a putter practice menu, and a registration data deletion menu can be selected. The address registration need not be performed every time the apparatus 10 is activated, and the address registration is completed if the triaxial acceleration data when the address was registered in the past is stored in the storage unit 117. Since the address-registered triaxial acceleration data is stored in the storage unit 117, which is a non-volatile memory, the triaxial acceleration data at the time of address registration in the past is stored in the storage unit 117 unless overwritten or deleted. ing. If the user U who is different from the most recently registered address uses the device 10, or if the same user U is changed to a grip or address posture different from that at the time of address registration, the address registration is performed again. Is desirable.

  On the other hand, if the variation in the output data of the acceleration sensor 112 does not fall within the predetermined range for the three axes even after the standby time elapses and the address cannot be detected, the screen returns to the address registration screen. The registration menu, putter practice menu, and registration data deletion menu remain in a non-selectable state.

  In the putter registration menu, the relationship between the takeback amount at the time of putting and the flight distance of the hit ball is registered. When the tact switch 150 is pressed for a short time with the putter registration menu selected, the putter registration start screen shown in FIG. 6C is displayed. When a short press of the tact switch 150 is recognized while the putter registration start screen is displayed, the address instruction screen shown in FIG. 6D is displayed to prompt the user U to take an address posture, similar to the case of address registration. . When the acceleration value output from the acceleration sensor 112 falls within the allowable value from the acceleration at the time of address registration stored in the storage unit 117 by address registration, it is recognized that the address posture has been taken, and the vibrator 113 is vibrated. The user is notified that the address has been detected, and the hitting instruction screen for prompting the putting shown in FIG. When the return button 141 is pressed while the pattern registration start screen is displayed, the screen returns to the green mode menu screen. If the address cannot be detected within a predetermined standby time (for example, 10 seconds) after the tact switch 150 is pressed for a short time with the putter registration start screen displayed, the screen returns to the putter registration start screen and the tact switch 150 is displayed. Waits for a short press again.

After the address is detected, the user U performs putting by adjusting the swing width while the hitting instruction screen is displayed. After address detection, the control unit 115 controls to start recording of the acceleration G _z in the Z-axis direction. When the apparatus 10 with the axial direction defined is attached as described above, the acceleration G _z tends to decrease when the takeback is performed, so the acceleration G _z shows a decreasing trend for a while. Thereafter, when the takeback is finished and the downswing is started, the acceleration G _z tends to increase and increases to a value exceeding the acceleration G _zad at the time of address detection. When the acceleration G _zad at the time of address detection is reached again, the control unit 115 controls to end the recording of the acceleration G _z . A value ΔG _z = G _zmin −G _zad obtained by subtracting the acceleration G _zad at the time of address detection from the recorded minimum value G _zmin of the acceleration G _z at the time of take back is used as an index of the magnitude of the take back. ΔG _z is an example of “data indicating the amount of takeback”.

After a predetermined time (e.g. 5 seconds) has elapsed from the address detection, displays the distance registration screen for confirming and selecting whether to store in association with the measured acceleration G _z in the distance (Fig. 6 (f)) . In the center of the flight distance registration screen, a flight distance selection list L1 for selecting the flight distance D of the hit ball by putting is displayed. The flight distance D is an example of “information related to swing strength”. The flight distance selection list L1 can be selected by a left / right swipe operation. The flight distance D in the flight distance selection list L1 is displayed in units of steps. While the golf course is rounded, there are restrictions on the distance measurement means that can be used. However, since the user U can measure the number of steps without using an instrument or the like, the flight distance selection list L1 is also a unit of steps. If the flight distance D is displayed and can be selected, the user U can easily select an appropriate flight distance. When registering, the user U measures the flight distance of the hit ball by the putting performed after the address detection, and selects the measured distance from the flight distance selection list L1. When the tact switch 150 in a state in which distance D is selected is pressed, in association with distance D value .DELTA.G _z and the user U obtained is selected by putting after address detection is stored in the storage unit 117 . Then, the fact that the registration has been made at the selected distance is displayed for 1 second, and then the putter registration start screen returns. When the return button 141 is pressed while the flight distance registration screen is displayed, the screen returns to the putter registration start screen. For example, when the user U does not wish to register the flight distance D, for example, when putting fails, the user can return to the putter registration start screen by pressing the return button 141 and start over.

The above pattern registration procedure can be performed a plurality of times, and a plurality of combinations of the flight distance and the value ΔG _z can be registered. A mathematical expression that approximates the relationship between the flight distance and the value ΔG _z is obtained from the combination of the registered flight distance and the value ΔG _z and stored in the storage unit 117. A mathematical formula that approximates the relationship between the flight distance and the value ΔG _z may be obtained by the least square method, and this mathematical formula may be a linear function passing through the origin, for example. By storing a formula that approximates the relationship between the distance and the value .DELTA.G _z, it is possible to store the correspondence between the data indicating the distance and take-back amount of the ball with less capacity.

  In addition to individual differences for each user U, the relationship between the takeback amount and the flight distance may vary depending on the physical condition of the playing day, the condition of the golf course, and the like. For this reason, before the start of play, it is desirable to register the relationship between the latest takeback amount and flight distance, for example, on a golf course practice green.

In the registration data deletion menu, old registration data is deleted at once before registering the relationship between the latest takeback amount and flight distance. When the pattern registration procedure is performed a plurality of times and a plurality of combinations of flight distances and values ΔG _z are stored in the storage unit 117, all combinations of flight distances and values ΔG _z are deleted, The mathematical formula that approximates the relationship of the value ΔG _z is also deleted from the storage unit 117. When tact switch 150 is pressed with registration data deletion selected on the green mode menu screen, the user U is requested to confirm the intention to delete data on the data deletion screen of FIG. If the intention was confirmed to do, return to the Green mode menu screen to remove all of the combination of distance and value ΔG _z, which was registered by the putter registration. On the other hand, when confirming the intention not to delete the data, the screen returns to the green mode menu screen without deleting the data as it is.

  In the putter practice menu, the takeback amount is notified according to the flying distance of the hit ball designated by the user U. The putter practice menu can be used to confirm the takeback amount suitable for the target flight distance when swinging before actually hitting the ball. Further, the user U may use the putter practice so that the user U is notified not only in the swing but also in the swing in which the ball is hit. It may not be used.

When the tact switch 150 is pressed with the putter practice menu selected, the target distance selection screen shown in FIG. 7B is displayed. In the center portion of the target distance selection screen, a target distance selection list L2 for selecting a target distance that is a distance to be skipped by putting will be displayed. In the target distance selection list L2, three target distances as selection branches are displayed on the screen of the display unit 170, and the center line among them is highlighted as being selected. The items in the target distance selection list L2 can be selected by an up / down swipe operation. The target distance in the target distance selection list L2 is displayed in units of steps. While the golf course is rounded, there are restrictions on the distance measuring means that can be used. However, since the user U can measure the number of steps to the target without using an instrument, the target distance menu L2 is also the number of steps. The user U can easily select an appropriate target distance if the target distance is displayed and selectable in units of. When the tact switch 150 is pressed for a short time with the target distance selected, the selected target distance is determined, the measurement start screen of FIG. 7C is displayed, and the relationship between the flight distance and the value ΔG _z is displayed. based on the formula that approximates to determine the desired value of the value .DELTA.G _z corresponding to the determined target distance. By using the mathematical formula, the target value can be calculated even when the value ΔG _z corresponding to the selected target distance is not stored in the storage unit 117.

  When the short press of the tact switch 150 is recognized while the measurement start screen is displayed, the address instruction screen shown in FIG. 7D is displayed to prompt the user U to take an address posture. When the acceleration value output from the acceleration sensor 112 falls within the allowable value from the acceleration at the time of address registration stored in the storage unit 117 by address registration, it is recognized that the address posture has been taken, and the vibrator 113 is vibrated. The user is notified that the address has been detected, and a swing instruction screen for prompting putting as shown in FIG. By notifying when the address is detected, the user U can confirm that the same address as that at the time of address registration is created. In particular, in the present embodiment, since the apparatus 10 is mounted on the wrist, the user U confirms that the same address posture as that at the time of registration is obtained including not only the club angle but also the grip method and grip state. be able to.

After address detection, the control unit 115 controls to start recording of the acceleration G _z in the Z-axis direction. When takeback is started in the same manner as described for the putter registration menu, the acceleration _Gz shows a decreasing tendency. User U starts the take-back, in accordance with gradually increasing the take-back, the acceleration G _z continues to decrease, the amount of change from G _z during the address reaches the target value of the value .DELTA.G _z. Upon reaching the target value of the value .DELTA.G _z, the control unit 115 recognizes that reaches the take-back amount suitable to target distance, to notify the user U to the vibrator 113 is vibrated to start the downswing. The user U can recognize that the downswing should be started with the takeback amount when the notification is received. If the address cannot be detected within a predetermined standby time (for example, 10 seconds) after the tact switch 150 is pressed for a short time with the measurement start screen displayed, the display returns to the target distance selection screen and the target distance is displayed. Wait for it to be selected.

  With the control as described above, in the putter practice menu, the takeback amount is notified according to the flying distance of the hit ball designated by the user U. The user U can adjust the swing width of the swing and adjust the flight distance by swinging based on this notification. In this way, the user U can be notified when the takeback amount corresponding to the designated flight distance of the hit ball has been reached. Therefore, by starting the downswing with the notified takeback amount, the swing can be performed with a stable takeback amount. The feeling of distance of putting is not the strength of how to put force at the time of impact, but it is correct to adjust by swing width. For this reason, the improvement of putting can be supported by notifying that the amount of takeback at the time of putting is stabilized. For example, if there are 4 steps from the current position of the ball to the cup, a notification to that effect can be received when the takeback amount suitable for the flight distance of the 4 steps is reached, so a downswing can be started from there. it can. As a result, the ball can be hit with the strength of four steps.

[Second Embodiment]
Similar to the device 10 of the first embodiment, the second embodiment of the present invention relates to a device 10 that assists golf play by notifying the user U according to the amount of takeback when putting. Below, it demonstrates centering on a different part from the apparatus 10 of 1st Embodiment.

  Control related to the appearance, configuration, mounting method, and operation of the device 10 is the same as that of the device 10 shown in FIGS. 1 to 4 except for control in the green mode described below.

In the device 10 of the second embodiment, the storage unit 117, as an indicator of take-back amount during putting the levels of a plurality (e.g., 20), the value .DELTA.G _z is an example of the "data showing the take-back amount" It is stored in advance in association with the target value. Here, as in the first embodiment, the value ΔG _z is a value ΔG _z = G _zmin −G _zad obtained by subtracting the acceleration G _zad at the time of address detection from the recorded minimum value G _zmin of the acceleration G _z at the time of _takeback . . The level is an example of “information about swing strength”.

Level, assuming the angle of the take-back as shown in Table 1, the standard grip, address position, and the target value of the value .DELTA.G _z corresponding to the angle of the take-back of swing is stored in the storage unit 117 Yes. Correspondence between the target value of the level value .DELTA.G _z are fixed.

  The level is associated with a smaller angle as the numerical value is smaller. In the range where the angle is small (2 to 30 degrees), the level is finely provided in small steps of about 2 degrees, and in the range where the angle is large (30 to 70 degrees), the level is roughly provided in increments of 5 to 10 degrees. Fine adjustment and adjustment of the flight distance is more important when approaching the cup on the green. By providing a level in a small angle range with fine angle steps, fine adjustment in short distance putting can be facilitated. On the other hand, a large angle range corresponds to putting a long distance, and in actual play it is assumed that the ball is brought near the cup to aim at the cup at the next putt rather than aiming at the cup directly at the putt. Is realistic. In such a method of use, the user U can adjust the rough distance without troublesome setting operation by providing levels in rough angle steps for a large angle range. The correspondence between the level and the angle is set so that the user U cannot change it. Note that the correspondence between the level and the angle is not necessarily accurate when grip, address posture, swing, etc. are not standard, so the user U is not presented with the specific size of the angle corresponding to the level, It is better to show it sensibly with the numerical value of the level.

  Hereinafter, regarding the operation of the apparatus 10 of the second embodiment, the control executed by the control unit 115 will be described. Note that the processing in which the subject is not specified in the following description is based on the control of the control unit 115. Functions and operations in the golf course guidance mode and operations until entering the green mode are the same as those of the apparatus 10. Description of these will be omitted to avoid duplication.

  When the green mode is entered, first, the green mode menu screen shown in FIG. 8A is displayed. On the green mode menu screen, a button B5 for selecting an address registration menu and a button B6 for selecting a pattern measurement menu are displayed so as to be selectable by touching the touch panel 140. The address registration menu is a menu for executing an address registration function for registering output data of the acceleration sensor 112 when the user U takes an address attitude, and is the same method as described in the device 10 of the first embodiment. Enables address registration at. When the address is not registered, the pattern measurement menu cannot be selected, and when the address is registered, the pattern measurement menu can be selected.

  In the putter measurement menu, the user U selects an arbitrary level and notifies the takeback amount according to the level. Also, the correspondence between each level and the flight distance can be registered. When button B6 is touched on the green mode menu screen, the level selection screen shown in FIG. 8B is displayed. In the center of the level selection screen, a level selection list L3 for selecting a plurality of levels that are indicators of the strength of putting and a step batch reset menu for deleting the flight distance D associated with each level at once. Is displayed. In the level selection list L3, three levels to be selected are displayed on the screen of the display unit 170, and the center row is highlighted while being selected. Items in the level selection list L3 can be selected by an up / down swipe operation. As options, level 1 to level 20 are displayed in ascending order from the top row, and the step count batch reset menu is displayed on the bottom row. In order to avoid unintentionally resetting the number of steps due to an erroneous operation, the top level 1 to level 3 may be displayed in the initial state. In the level selection menu, the flight distance D can be displayed in association with each level. The flight distance D associated with the level is displayed as registered by the flight distance registration described below, and the level indicating that the corresponding flight distance D is not registered is displayed indicating that it is not registered (for example, (“* Step” shown on the right side of the level in FIG. 8B). While the golf course is rounded, there are restrictions on the distance measuring means that can be used. However, since the user U can measure the number of steps without using an instrument or the like, it is associated with the level in the level selection list L3. If the flying distance D to be displayed is displayed in units of steps and can be selected, the user U can easily select a level corresponding to the appropriate flying distance D. By displaying a list so that the level and the flight distance D can be compared using such a level selection list L3, the user U can easily recognize whether or not the flight distance D corresponding to each level is registered. can do. Further, by displaying the level selection list L3 in ascending order from level 1 to level 20, the registered abnormal value of the flying distance D can be easily recognized by the user U. For example, when the flight distance D registered in ascending order from level 1 is confirmed, if the flight distance D does not increase monotonously with respect to the level increase, the user U has an abnormal value in the registered flight distance D. It can be determined that it is included.

  When the tact switch 150 is pressed for a short time with the level selected, the selected level is determined and the measurement / registration selection screen is displayed. FIG. 8C shows an example of a measurement / registration selection screen when level 2 is selected. The measurement / registration selection screen displays the selected level and the distance corresponding to the level, and touches the touch panel 140 with a button B7 for selecting the measurement menu and a button B8 for selecting the flight distance registration menu. Is displayed in a selectable manner. At this point, since the flight distance D is not registered in level 2, “** steps” is displayed as shown in FIG. 8C, and the user U can easily recognize that the flight distance D is not registered. doing. When the return button 141 is pressed while the measurement / registration selection screen is displayed, the screen returns to the level selection screen.

  The measurement menu notifies the takeback amount according to the selected level. This measurement menu can be used when swinging or hitting the green during play, or can be used to associate the flight distance D with the level.

  When a touch on the measurement menu is recognized on the measurement / registration selection screen, the address instruction screen in FIG. 8D is displayed to prompt the user U to take an address posture. On this address instruction screen, an end button is displayed in addition to a display prompting to take an address posture. When the touch on the end button is recognized, the screen returns to the measurement / registration selection screen. The acceleration at the time of address registration in which the user U takes an address posture while the address instruction screen of FIG. 8D is displayed and the acceleration value output from the acceleration sensor 112 is stored in the storage unit 117 by address registration. If it falls within the allowable value from the position, it is recognized that the address posture has been taken, the vibrator 113 is vibrated to notify the user that the address has been detected, and the display unit 170 has a swing as shown in FIG. A swing instruction screen for prompting is displayed.

After address detection, the control unit 115 controls to start recording of the acceleration G _z in the Z-axis direction. When takeback is started in the same manner as described for the putter registration in the first embodiment, the acceleration _Gz shows a decreasing tendency. User U starts the take-back, in accordance with gradually increasing the take-back, the acceleration G _z continues to decrease, the amount of change from G _z during the address reaches the target value of the value .DELTA.G _z. Upon reaching the target value of the value .DELTA.G _z, the control unit 115 recognizes that reaches the take-back amount suitable to target distance, to notify the user U to the vibrator 113 is vibrated to start the downswing. The user U can recognize that the downswing should be started with the takeback amount when the notification is received, and can actually check the flight distance by putting.

When it is detected that reaches the target value of the value .DELTA.G _z, it returns the address instruction screen in FIG. 8 (d), the wait for the address position is again taken. Also, it waits for the target distance to be selected. Incidentally, after the address detection, if it can not detect that it has reached a value .DELTA.G _z within between predetermined standby time (for example, 10 seconds), the process returns to the address instruction screen in FIG. 8 (d), the address position is taken Wait for. Thus, by the control to return to the address instruction screen in FIG. 8D, repeated measurement can be performed by re-taking the address posture without any particular operation. For example, if you repeat swinging to confirm the appropriate takeback amount before hitting the ball, or if you put off again when you register the flight distance D, you only need to take the address posture without any operation. Re-measurement becomes possible.

  In the flight distance registration menu, the flight distance D is registered in association with the currently selected level. When the touch on the flight distance registration menu is recognized on the measurement / registration selection screen, the flight distance registration screen of FIG. 8F is displayed. The user U receives the notification of the takeback amount corresponding to the selected level by measurement, performs the putting, confirms the flying distance D in the putting, and registers the flying distance D in association with the level. Touch the registration menu. In the center of the flight distance registration screen, a flight distance selection for selecting a step count reset menu for resetting the flight distance D of the hit ball by putting and the flight distance D registered in association with the currently selected level. List L4 is displayed. The flight distance D in the flight distance selection list L4 is displayed in units of steps. While the golf course is rounded, there are restrictions on the distance measuring means that can be used. However, since the user U can measure the number of steps without using an instrument or the like, the flight distance selection list L4 is also a unit of steps. If the flight distance D is displayed and can be selected, the user U can easily select an appropriate flight distance. In addition, it is easy to quickly measure and set a long distance according to the user U's stride, and when the distance estimated by the user U by eye measurement is set in the apparatus 10, it is relatively accurate based on his / her sense. The distance can be estimated and set in the device 10. The flight distance selection list L4 displays three selected branches on the screen of the display unit 170, and highlights the center row among them as being selected. Items in the flight distance selection list L4 can be selected by an up / down swipe operation. As options, the number of steps from 1 step to 50 steps as options of the flight distance D is displayed in ascending order from the top row, and a step count reset menu for deleting the number of steps associated with the level is displayed on the bottom row. To do. In order to avoid unintentionally resetting the number of steps due to an erroneous operation, it is preferable to display the top 1 to 3 steps in the initial state.

  When the tact switch 150 is pressed while the flight distance D is selected, the selected flight distance D is stored in the storage unit 117 in association with the selected level, and the measurement / registration selection screen is displayed again. At this time, on the measurement / registration selection screen, as shown in FIG. 9A, the registered flight distance D is displayed together with the selected level. When the return button 141 is pressed from the display state of the measurement / registration selection screen after the flight distance D is registered to return to the level selection screen, registration is performed in association with the level in the level selection list L3 as shown in FIG. 9B. The flying distance D is displayed. It is not necessary to register the flight distance D for all levels, and the user U may register the flight distance D for some selected levels. For example, by registering the flight distance D at a predetermined level every time, it is possible to grasp the ease of rolling of the hit ball in the condition of the day. A list is displayed in the level selection list L3 so that the level and the flight distance D can be compared. When the flight distance D data corresponding to a certain level has been registered for the previous play and the flight distance D data is to be updated, a notification is received at one level and the ball is hit By comparing the actual flight distance and the flight distance D at the previous registration, it is possible to easily grasp the tendency of the flight distance in the condition of the day. In addition, if the flight distance was the same as the previous registration, it can be assumed that the flight distances corresponding to the other setting values displayed in the list are the same as the previous one. It can be simplified.

  When the tact switch 150 is pressed for a short time while the step count batch reset menu is selected on the level selection screen, the number of steps associated with all levels is deleted on the data deletion screen similar to FIG. When the user U's intention to confirm is confirmed and the intention to delete is confirmed, all the data of the number of steps stored in the storage unit 117 in association with the level is deleted and the screen returns to the level selection screen. On the other hand, when confirming the intention not to delete the data, the screen returns to the level selection screen without deleting the data as it is.

  By the control as described above, the apparatus 10 of the second embodiment notifies the takeback amount according to the level designated by the user U. The user U can be notified when the takeback amount corresponding to the designated level is reached. Therefore, by starting the downswing with the notified takeback amount, the swing can be performed with a stable takeback amount. Since it is said that the strength of putting is adjusted correctly by the swing width of the swing rather than the amount of force at the time of impact, this book can be notified by quantifying the amount of takeback that determines the swing width of the swing The configuration of the embodiment contributes to improvement of the putting technique. Further, by registering the flight distance in association with the level, the user can recognize the flight distance corresponding to the level. Then, the user U can substantially specify the flight distance and receive a takeback amount notification corresponding to the flight distance.

[Third Embodiment]
3rd Embodiment of this invention is related with the apparatus 10 which notifies the user U according to the amount of takeback at the time of putting, and supports the play of golf similarly to the apparatus 10 of 1st Embodiment or 2nd Embodiment. The appearance, configuration, and mounting method of the device 10 are the same as those of the device 10 shown in FIGS. Below, it demonstrates centering on the point which uses the data which show the amount of takebacks different from the apparatus 10 of 1st Embodiment and 2nd Embodiment, and the change accompanying this.

  The movement of the putter head (hereinafter also referred to as a stroke type) when putting is varied depending on the player. For example, as shown in FIG. 10 (a), a straight type in which the head is moved straight along the flying ball direction (the one-dot chain line in the figure) that is the traveling direction of the hit ball, as shown in FIG. 10 (b), the arc An arc type in which the head is moved so as to draw a stroke is a typical head movement. In addition, there is a semi-arc type in which the head is moved with a looser arc than the arc type. These stroke types do not have the only ideal movement, but putters having shapes suitable for the respective stroke types are provided. In addition to the above stroke type variations as seen from above, there are players who pull the club head to slide along the ground without floating while the swing width is small, when taking back. Some players float the character head from the initial stage of takeback.

  As described above, when the swing is performed with various stroke types, the inventors have found that the acceleration detected by the acceleration sensor 112 has the following difference due to the difference in the stroke type. In the case of the straight type, when the takeback amount increases, in the top view shown in FIG. 11 (a), the head moves rearward along the flying ball direction (the one-dot chain line in the drawing), along with the side view. As shown in FIG. 11B, it is pulled up relatively large in the vertical direction. On the other hand, in the case of the arc type, as shown in the top view (FIG. 12A), the head deviates from the flying ball direction (dashed line in the figure) during takeback, and the head increases as the takeback amount increases. The amount of movement of the user U in the back direction increases and the amount of movement in the rearward direction of the flying ball line is relatively small. In the case of the arc type, as shown in the side view (FIG. 12B), the moving amount of the head in the vertical direction with the increase in the takeback amount is relatively small.

When the acceleration sensor 112 is arranged so that the three axes are in the direction shown in FIG. 1, when the right-handed user U wears the device 10 on the left hand, the movement that pulls straight back along the flying ball direction Is mainly detected as acceleration in the Z-axis direction. The movement of the user U in the back direction is mainly detected as acceleration in the X-axis direction. The vertical movement is detected mainly by acceleration in the Y-axis direction. Therefore, in the straight type swing, the displacement amount ΔG _z from the address of the acceleration G _{z in} the Z-axis direction changes substantially linearly with an increase in the takeback amount. On the other hand, as in the arc type or semi-arc type, the swing with the movement of the head toward the back of the user U, .DELTA.G _z does not change linearly with respect to the take-back amount, the value when the take-back amount increases It becomes hard to change. Further, there is a difference in vertical movement between the straight type and the arc type. In addition, when taking back, the detected acceleration of the swing that slides along the ground without lifting the club head while the swing width is small and the swing that lifts the character head from the stage where the takeback amount is small are detected. There is a difference in the components in each axial direction.

  Based on the tendency found by the inventors, it is preferable to use “data indicating the takeback amount” in consideration of acceleration in the X-axis direction and the Y-axis direction. It is preferable that the user U using the device 10 is configured to receive a notification corresponding to the takeback amount without being conscious of his / her stroke type. Therefore, in the present embodiment, the amplitude determination value S, which is an index that changes almost linearly regardless of the stroke type, is added to the “takeback” in consideration of the acceleration in the X axis direction and the Y axis direction as well as the Z axis direction. Used as “data indicating quantity”.

First, output data (G _x , G _y , G _z ) of the acceleration sensor 112 is converted from orthogonal coordinates by three axes of X, Y, and Z to polar coordinates (G _r , G _θ , G _φ ). Specifically, G _r = √ (G _x ² + G _y ² + G _z ² ), G _θ = arcsin (G _z / G _r ), G _φ = arctan (G _y / G _x ), and orthogonal coordinates to polar coordinates Convert to. _{Subsequently, G x '= cosG φ,} G y' = cosG θ, further converts the coordinate system based on the equation of _{G z} '= _{sinG θ.} In the conversion of the additional coordinate system, by not using a G _r, to remove the differences in acceleration due to the mounting position of the arm length and apparatus 10 of the user U, it focuses on the size and angle of the take-back Can do.

Then, to calculate the index P as _{P = 3 × G x '-6} × G y' -G z '. The index P is an index found by the inventors as a result of numerous trials and errors, and the takeback amount can be substantially linearly adjusted with respect to various stroke type swings by weighting and adjusting the components in each axial direction. The reflected value changes.

  Subsequently, the determination value S corresponding to the value of the index P is obtained by referring to the conversion table stored in advance in the storage unit 117. In the conversion table shown in Table 2, the index value P in a range corresponding to an angle of about −30 degrees to about +45 degrees when the direction in which takeback is increased in a general straight type swing is positive is 170 pieces. Corresponds to an integer value. Therefore, a difference of 1 in the swing width determination value S corresponds to a takeback angle of about 0.4 degrees. By using the conversion table, the processing can be simplified and the processing time can be shortened.

  In the apparatus 10 of the third embodiment, the swing width determination value S obtained in this way is used as an index of the magnitude of takeback. That is, the swing width determination value S is an example of “data indicating a takeback amount”.

  In the apparatus 10 of the third embodiment, as shown in Table 3, the storage unit 117 associates a plurality of levels (for example, 20) with the variation ΔS of the swing width determination value S, and puts the level for each level. It is stored in advance as an index of the takeback amount. The level is an example of “information related to swing strength”, and Table 3 is an example of “correspondence between information related to swing strength and data indicating the amount of takeback based on the output of the detection unit”.

  Hereinafter, the control executed by the control unit 115 will be described with respect to the operation of the apparatus 10 of the third embodiment. Note that the processing in which the subject is not specified in the following description is based on the control of the control unit 115. In the apparatus 10 of the present embodiment, the takeback amount corresponding to the level designated by the user U is notified in the green mode by the same method as in the second embodiment. Functions and operations in the golf course guidance mode and operations until entering the green mode are the same as those of the apparatus 10. Description of these will be omitted to avoid duplication.

  When the green mode is entered, the green mode menu screen shown in FIG. 8A is displayed first. If no address is registered, only the address registration menu can be selected. The address registration menu is a menu for executing an address registration function for registering output data of the acceleration sensor 112 when the user U takes an address attitude, and is the same method as described in the device 10 of the first embodiment. Enables address registration at.

  In the pattern measurement menu that can be selected when the address registration has been completed, the user U selects an arbitrary level and notifies the takeback amount according to the level. Also, the correspondence between each level and the flight distance can be registered. When a button B6 for selecting a pattern measurement menu is touched on the green mode menu screen, a level selection screen (FIG. 8B) is displayed. Select a level on this level selection screen. When the tact switch 150 is pressed for a short time with the level selected, the selected level is determined and the measurement / registration selection screen (FIG. 8C) is displayed. When a level is selected, a change amount ΔS corresponding to the level is determined.

When a touch on the measurement menu is recognized on the measurement / registration selection screen, the address instruction screen in FIG. 8D is displayed to prompt the user U to take an address posture, and the address instruction screen is displayed. The user U takes an address attitude, continues for a predetermined determination time (for example, 2 seconds), and the variation in the output data of the acceleration sensor 112 falls within a predetermined range (for example, 0.1 G) for all three axes. When it falls within the allowable value from the acceleration at the time of address registration stored in the storage unit 117, it recognizes that the address posture has been taken, notifies the user that the address has been detected by vibrating the vibrator 113, and displays it on the display unit 170. Displays a swing instruction screen for prompting a swing as shown in FIG. Further, by a variation [Delta] S in accordance with the swing width determination value S _ad and level at address target value _{S targ} swing amount determination value _S, to determine the _{S targ} = _{S ad} + ΔS.

After the address detection, the control unit 115 obtains the swing width determination value S as needed based on the output data of the acceleration sensor 112. When takeback is started, the swing width determination value S shows an increasing tendency. User U starts the take-back, in accordance with gradually increasing the take-back, the increase continues swing width determination value S, finally reaches the target value S _targ. When swing width determination value S reaches the target value S _targ, the control unit 115 recognizes that reaches the take-back amount suitable to target distance, to notify the user U to the vibrator 113 is vibrated to start the downswing . The user U can recognize that the downswing should be started with the takeback amount when the notification is received, and can actually check the flight distance by putting. Since the apparatus 10 according to the present embodiment uses the swing determination value S that is an index that includes acceleration in the X-axis direction and the Y-axis direction as well as the Z-axis direction, the user U depends on the swing stroke type. Therefore, it is possible to receive a notification of the takeback amount corresponding to the level, and to perform a swing with a desired sense of distance. As a result, it is easy to obtain the target flight distance, and it can be expected to improve the number of hits of the putt.

[Fourth Embodiment]
4th Embodiment of this invention is related with the apparatus 10 which notifies the user U according to the amount of takeback at the time of putting, and supports the play of golf similarly to the apparatus 10 of the above-mentioned 1st-3rd embodiment. The appearance, configuration, and mounting method of the device 10 are the same as those of the device 10 shown in FIGS. The apparatus according to the present embodiment is different in that control is performed to vary the magnitude of the takeback amount to be notified in accordance with the inclination in the traveling direction of the hit ball in the measurement menu, and the other points are the apparatus 10 according to the third embodiment. It is the same. Below, the part which becomes the characteristic of this embodiment is demonstrated.

  In the device 10 of the fourth embodiment, the inclination is obtained based on the acceleration at the time of address registration. For this reason, the address registration performed by selecting the address registration menu is performed in a substantially horizontal place (for example, a place without a large inclination such as a golf practice green or a tee ground).

In the measurement menu for take-back amount of the notification according to the level, in the third embodiment, by the ΔS corresponding to the swing width determination value S _ad and level at address target value S _targ swing amount determination value S, S _target = S _ad + ΔS was determined. On the other hand, in the fourth embodiment, the inclination correction value S _comp for reducing the influence of the inclination in the traveling direction is reflected and determined.

The inclination correction value S _comp is obtained by the following procedure. First, the inclination in the traveling direction of the hit ball is obtained at the timing when the address is detected. Specifically, it is obtained from the reference amplitude determination value S _ref obtained from the output data of the acceleration sensor at the time of address registration stored in the storage unit 117 and the output data of the acceleration sensor when the address is detected in the swing. the difference between the S _ad the _{(S ad -S ref),} calculated as an indicator of tilting in the traveling direction of the ball. When the value of this index is negative, it is an upward slope, and when it is positive, it is a downward slope. The size of the gradient is represented by the absolute value of _S ad _{-S ref.}

Tilt correction value _{S comp is} the _{S comp = (S ad -S ref} ) × 0.5, the target value _{S targ} swing amount determination value S _is determined as _{S targ = S ad + ΔS-} S comp. In this way, determines a large target value S _targ than in the horizontal location in the uplink of inclination, yet larger take-back amount as the inclination is steep is to be notified. Conversely, a small target value S _targ is determined than in the horizontal location in the slope of the downstream, yet smaller take-back amount as the inclination is steep is to be notified.

  If it does in this way, the user U who uses the apparatus 10 of this embodiment can perform a swing with the takeback amount adjusted based on the inclination of the hitting ball position. If putting is performed in accordance with the notification, it is possible to easily obtain the target flight distance with a sense of distance equivalent to that when the place is flat, and it can be expected to improve the number of hits of the putt.

[Modification of Embodiment]
The present invention is not limited to the above embodiments, and modifications, improvements, and the like are included in the present invention.
For example, in the above embodiment, the green mode is selected by a manual operation by the user U, but the green mode may be automatically activated. For example, the green mode may be automatically activated based on the current position information acquired by the GPS receiver 111 and the golf course information stored in the storage unit 117. For example, if the current location is a golf practice green suitable for using the green mode, or a golf clubhouse or other meeting place where a round is expected to start soon In addition, it is good to activate the green mode. Alternatively, instead of automatically starting the green mode, a screen that prompts the user to use the green mode may be displayed on the display unit 170. In this case, it is particularly preferable to display a menu button for starting the green mode in the screen.

  Further, in each of the above embodiments, the user U is notified by the vibration of the vibrator 113. However, in the configuration including a display on the display unit 170 and a sound output unit such as a speaker and a buzzer, a sound by the sound output unit, etc. Notification may be performed by. In a round at a golf course, notification by voice or the like is not preferable in view of play manners, but it may be preferable to notify by voice or the like at a place other than a home or other golf course. For example, the notification by vibration generates unusual vibration on the wrist of the hand holding the golf club, which may cause a slight deviation in the grip. For this reason, it is good to comprise so that notification by methods other than a vibration can be selected in the environment where notification is permitted by methods other than vibration.

In each of the above embodiments, the notification is performed when the value ΔG _z indicating the takeback amount reaches the target value. However, the notification is performed when the value does not reach the target value and / or after the target value is exceeded. You may do it. In the case of notifying by vibration of the vibrator 113, it is preferable that the vibration patterns are different from each other when the target value is not reached, at the moment of reaching, and after exceeding. In the case of notifying by voice, it may be notified by different sounds when the target value is not reached, at the moment of reaching, and after exceeding.

In each of the embodiments described above, the "data showing the take-back amount", is used a value .DELTA.G _z and swing width determination value S, the data indicating the take-back amount in the index for change to reflect the take-back amount Other indicators may be used as long as they are present. For example, the amount of change from the value at the address of G _z -G _{y obtained} by subtracting the acceleration in the Y-axis direction from the acceleration in the Z-axis direction may be used as “data indicating the takeback amount”. And at least one of the acceleration component in the vertical direction and a value obtained by adding different weights to the acceleration component in the traveling direction of the hit ball. The weight of each component may be determined so that the sensitivity for various swings is comparable.

  In the above embodiment, when an address cannot be detected within a predetermined standby time in the address registration menu, the user may be notified that the address has not been detected. The notification may be performed by voice or display, but it is particularly good from the viewpoint of play manner if it is performed by a vibration pattern different from that when the address is detected.

  In each of the above embodiments, the distance is displayed in units of the number of steps in the flight distance selection list L1, the target distance selection list L2, the level selection list L3, and the flight distance selection list L4. May be. The unit is preferably displayed using a unit of distance measuring means that can be used while rounding the golf course, and for example, the length of the golf club may be displayed as a unit.

In the second embodiment, the target value ΔG _z corresponding to each level is fixed. However, even if the value ΔG _z corresponding to each level is corrected according to the acceleration data registered at the address, the target value ΔG _z corresponding to each level is fixed. Good. For example, there are a standard address posture (see FIG. 13 (a)) that draws a triangle when tied along the arm from both shoulders to the grip, and an address posture (see FIG. 13 (b)) that draws a pentagon. The address attitude is different for each individual user. When the address position is different, since the orientation of the device 10 with respect to the club different, when determining the target value according to the corresponding relationship between the target value of the standard address attitude level set by assuming the value .DELTA.G _z, the angle steps Although it may deviate from the assumptions shown in Table 1, by correcting based on the acceleration data registered in the address, even if the address posture is not standard, it corresponds to the angle assumed for each level target value .DELTA.G _z to can be set.

  In the above embodiment, the device 10 is mounted on the wrist of the user U. However, as shown in FIG. 14, the device 10 may be configured to be attached to the shaft of the golf club. In this way, the movement of the golf club can be directly detected, and the swing width of the swing can be accurately measured. When the device 10 is configured to be attached to the shaft of the golf club, the case 110 may be configured to be removable from the jacket portion of the band 120, and the removed case 110 may be configured to be attached to the holder 20 attached to the shaft. The holder may hold the case 110 of the device 10 so as to have the same angle as when the device is attached to the wrist of a user in a standard address posture with the band 120.

  Further, among the components of the apparatus 10, the sensor unit including the acceleration sensor 112 is attached to the shaft of the golf club, and the user interface unit including the display unit 170, the touch panel 140, the tact switch 150, and the like is the same as that of the above embodiment. It may be configured to be worn on the wrist, perform wireless communication between the sensor unit and the user interface unit, and realize the same function as the device 10. According to such a configuration, it is possible to easily measure the swing width of the swing while easily operating the apparatus naturally. As a further modification, the sensor unit including the acceleration sensor 112 may be configured to be attached to the head of the golf club. In this way, the swing width of the golf club head that directly hits the ball at the time of hitting can be accurately measured, and the user U can receive a notification based on the correct swing width.

  In the above embodiment, the apparatus 10 is used for adjusting the takeback amount of putting by the putter. However, the apparatus 10 may be applied to adjusting the swing of a club other than the putter. For example, it may be a club used for approach shots. In approach shots that adjust the flight distance according to the distance to the target in the same club instead of simply pursuing a long flight distance, the same method as in the above embodiment is applied to notify the swing amplitude of the swing. By receiving it, it is possible to assist in adjusting or adjusting the flight distance.

  In the third embodiment, the index P is converted into the swing width determination value S, and the swing width determination value S is “data indicating the takeback amount”. However, the index P is “data indicating the takeback amount”. It is good also as.

In the third embodiment, P = 3 × G _x ′ −6 × G _y ′ −G _z ′ is used as the index P, but at least the straight type and the arc type stroke type tend to have a common tendency. Any index may be used as long as it changes according to the amount. The index to be used preferably has a tendency to change linearly with respect to the takeback amount. In addition, when taking back, a swing that slides along the ground without lifting the club head as long as the swing width is small, and a swing that lifts the character head from the initial stage of takeback are common. It is preferable to change according to the takeback amount in a tendency. In addition, the index to be used varies in accordance with the takeback amount with a common tendency between the swing in the address posture shown in FIG. 13A and the swing in the address posture shown in FIG. It is preferable.

  In the third and fourth embodiments described above, the takeback amount corresponding to the level designated by the user U is notified by the same method as in the second embodiment, but the same as in the first embodiment. The relationship between the take-back amount and the flight distance in the swing of the user U himself is registered in advance, the take-back amount corresponding to the flight distance designated by the user U is obtained, and the obtained take-back amount You may make it notify by.

  Further, the same control as in the fourth embodiment described above, in which the magnitude of the takeback amount to be notified according to the inclination in the traveling direction of the hit ball may be applied to the first embodiment and the second embodiment.

  Moreover, you may use the inclination correction value different from said 4th Embodiment. For example, the absolute value of the inclination correction value is set to a constant value, and the constant inclination correction value is added to the target value so that the takeback amount increases in the upward inclination, and the takeback amount decreases in the downward inclination. As described above, the fixed inclination correction value may be subtracted from the target value. In this way, the calculation amount and storage capacity required for correction can be reduced.

  In addition, control other than adding or subtracting the correction value to or from the target value may be performed to change the magnitude of the takeback amount to be notified according to the inclination of the hit ball in the traveling direction. For example, a correction value corresponding to the inclination may be added to or subtracted from the swing width determination value S.

  The present invention is not limited to the configuration described in the above embodiment. The constituent elements of the above-described embodiments may be arbitrarily selected and combined within a combinable range. In addition, any component in each embodiment can be combined with any component described in the means for solving the invention or a component embodying any component described in the means for solving the invention. It may be configured by arbitrarily combining within such a range.
