Description

{A portable golf advice aid device and its method}

The present invention relates to a portable golf advice assisting device and method, and more particularly, informs a user of information on an optimal course strategy suitable for an individual's skill, and identifies the user's actual address posture or alignment direction to enable the user to adjust the address posture or The present invention relates to a portable golf advice assisting device and method for correcting an alignment direction to be consistent with optimal course strategy information.

Golf is a game in which superiority is determined according to the number of strokes required in the process of hitting a golf ball with a club and putting it into a hole. it is important

That is, information about the arrangement of holes, teeing ground, fairway, rough, hazard, putting green, out of bounds, etc. Knowing it correctly is important to reduce the number of strokes.

In particular, since various obstacles such as forests, ponds, valleys, and mountains are installed in the golf course, information on these obstacles must be grasped. In addition, the golfer must identify not only the information of the golf course but also information such as his or her skill and climatic conditions, and select a hitting strategy that minimizes the number of strokes required for each hitting, that is, a strategy. In addition, since the position of the hole cup, the first hitting point, the position of an obstacle, etc. may vary, it is important to select a strategy taking this into consideration.

In general, a golfer selects a strategy based on information identified with the naked eye, information recognized in advance, and his or her own ability. For example, the position of the hole identified with the naked eye, the distance from the hitting point to the hole, the location of the obstacle and the attack information obtained through direct experience or indirectly, and hitting at a specific hitting point based on one's own strength and skill strategy will be established.

In addition, when information on the golf course is insufficient, the golfer can proceed with the game with the help of a game assistant (caddy) in order to obtain more accurate information. You can also get help from the match assistant in selecting the hitting method.

In recent years, prior art has been proposed that uses a global positioning system (GPS) to identify a golfer's location and provide the golfer with previously input golf course information so that the golfer can use it as a means of selecting a strategy.

For example, the portable terminal and method of the golf information system according to Korean Patent Application Laid-Open No. 2002-0036361 includes a host computer unit and a portable terminal of the control unit containing the golf course situation, and the host computer provides an image of the entire golf course hole. and location data are recorded, and the location of the hole cup that changes every day is recorded and preserved. It is constructed by inserting a GPS module, and the golfer provides a system and method to easily hit a ball using the identified distance information by checking various information of a golf hole and location information/distance within the hole.

For another example, a method for providing golf course information using a GPS-enabled mobile phone according to Republic of Korea Patent Publication No. 10-2005-022035 and a device therefor builds a database of course map data of each course of a golf course in an information providing server and builds it in an information database, , if there is a customer's request, it is downloaded to the customer terminal, and when the hole number of the golf course is selected, the customer terminal receives the GPS signal through the GPS satellite and calculates the coordinates of the current location, and the green of the hole at the current location By displaying the distance to the screen, and calculating the distance from your location to each location (green, obstacle, front of the green, bunker, hazard, etc.) It helps to play a golf game, and also promotes the improvement of the golf player's performance.

However, although the prior art provides golf course information to facilitate a golfer to plan a course attack method, the course attack method of the prior art is not provided in consideration of the golfer's skill or habit, etc. There is a problem that is not suitable for them.

In addition, even if the above prior arts suggest a course attack method, there is no function to check whether each golfer plays according to the presented course attack method. Since it cannot be confirmed whether the method is performed according to the method, there is a problem in that the effect of improving the golfer's performance or reducing the number of strokes is halved even using the course attack method of the prior art.

Accordingly, there is a need to develop a new and more advanced golf assisting device and method capable of improving the above-described problems.

In order to do this, it is necessary to resolve these errors.

In golf, putting the golf ball into the hole cup by accurately grasping the curve on the green or the inclination of the green, striking the golf ball with an appropriate strength and direction. However, in golf, putting accounts for half of the golf score, so it has a very large effect on the golf score, so it is very important to accurately analyze the distance on the green or the slope of the green.

Generally, golfers lie on the green or lie down on the green to analyze the inclination between the golf ball and the hole cup before putting on the green.

In addition, while walking on the green, most golfers measure the distance to the hole cup, the slope of the green, etc. using the stride length or the sense of the soles of the feet. Although the intensity and the like have been set, the stride length and sensation are different for each individual and may vary depending on the situation at the time of a golf game, so it is not easy to grasp accurate green information.

In the present invention, in order to solve the inaccuracy of the green information provided by the server unit 120 or the inaccuracy of grasping the green characteristics depending on the general golfers' vision or walking sense, a separate measuring means for measuring the green characteristics is used.

First, in the present invention, when the golfer selects the putting strategy information 230 menu in the seventh step (S7), the course information obtained through the fourth step (S4) is identified, and then the green measurement is performed in the eighth step (S8) A green measuring device use menu 231 for checking whether the device is used is displayed.

If the green measuring device use is selected in the green measuring device use menu 231 of the eighth step (S8), then the green measuring device 500 and the mobile device 110 are linked in the ninth step (S9) to measure the green The device linkage menu 232 is displayed to allow the golfer to select it. The interworking of the two devices is possible using a short-distance communication method such as Bluetooth or Ultra Wide Band (UWB) communication.

When the linkage with the green measuring device in the ninth step (S9) is completed, in the tenth step (S10), the green measuring mode 233 menu is displayed for the golfer to select, and the green measuring device 500 is used to characterize the green is directly measured and the measured value is transmitted to the mobile device 110 .

When the green measurement of the tenth step (S10) is completed, the putting strategy information creation (234) menu is performed at the time the golfer is ready to put in the eleventh step (S11), but the server obtained in the seventh step (S7) Putting strategy information is provided to the golfer using the course information of the unit and the measured value of the green measuring device 500 . When the eleventh step (S11) is performed, the link between the mobile device and the green measuring device is released, and the green measuring device maintains an off state.

The putting strategy information of the present invention includes a putting distance, a putting direction, and a deflection distance based on a hole cup, and displays a putting leader line indicating the putting distance and the putting direction on the display unit 113 .

The putting direction and the ball trajectory may be graphically displayed on the display unit 113 based on information such as the putting distance, the green slope, and the green speed. The actual putting direction up to can be displayed with a putting leader line.

When the golfer selects the putting address information 240 menu in the thirteenth step (S13), the alignment line 610 of both feet is identified in the same manner as in the sixth step (S6) and displayed on the display unit 113 using the AR function. After displaying, the golfer aligns the alignment line 610 with both feet to be parallel to the putting instruction line of the display unit 113, and then puts the ball into the hole cup due to the vertical inclination of the green.

If the golfer uses the golf ball on which the alignment line is displayed in the 13th step (S13), the advice generating unit 200 automatically recognizes the golf ball alignment line along with the golf shoe using an artificial intelligence technique, and uses the AR function. displayed on the display unit 113 .

In this case, since the display unit 113 displays the alignment line of both feet, the putting leader line, and the golf ball alignment line using the AR function at the same time, the golfer puts the golf ball alignment line and the both feet alignment line while looking at the mobile phone screen or AR glasses before putting You can make the putt parallel to the leader line.

In addition, in the case of using an earphone interlocked with the mobile device 110 in the thirteenth step (S13), the advice generating unit 200 calculates the deviation between the alignment line of both feet and the putting guide line, and provides the golfer with the deviation by using the earphone as a voice. You can tell it to resolve the deviation between the alignment line of both feet and the putting leader line.

If the use of the green measuring device is not selected in the eighth step (S8), the putting strategy information is generated by performing the putting strategy information generation (234) menu based only on the green information obtained from the server unit of the fourth step (S4). do. The putting strategy information of the twelfth step (S12) includes the putting distance, the putting direction, and the deflection distance based on the hole cup, and the display unit 113 includes the putting distance, the putting direction, the deflection distance based on the hole cup, and the curvature of the green. A green map is displayed, and in particular, the putting distance and the putting direction indicating the putting direction 620 and the azimuth angle of the putting leader line 620 are displayed.

When the golfer selects the putting address information 240 menu after the twelfth step (S12), the foot alignment line 610 is identified and displayed on the display unit 113 in the same manner as the 61st step (S61), and the golfer Putting is performed after matching the alignment line 610 of both feet to be parallel to the putting instruction line of the display unit 113 .

Next, the green measuring device 500 used in the ninth step ( S9 ) will be described in detail with reference to FIG. 5 .

The green measuring device 500 of the present invention can be a lidar sensor, an optical sensor, a camera sensor, etc. capable of measuring the inclination or curvature of the green, but the green measuring device 500 in the present invention is a green that can be attached to and detached from the golf shoe 510 . It is configured to include one or more of the measurement sensor module 520 and the weight detection module 540 attached to the golf shoe insole 530 .

The green measurement sensor module 520 of the present invention includes at least one of a 3-axis acceleration sensor for measuring 3-axis acceleration, a 3-axis gyro sensor for measuring angular velocity, a geomagnetic sensor, and a GPS sensor, and is a detachable configuration such as Velcro. is attached to the golf shoe 510 using Assess the distance and impact force when walking.

In addition, the green measurement sensor module 520 may include a transmission/reception module to enable transmission/reception using a short-distance communication method with a golfer's mobile device, and may separately include a small battery for operation.

In the weight sensing module 540 of the present invention, a piezoelectric sensor array is attached to the golf shoe insole 530, and is attached so as to sense all possible load distribution on the sole of the golfer's foot. A transmission/reception module may be provided to enable this, and a small battery for operation may be separately provided. By using the weight sensing module 540 of the present invention, it is possible to sense the weight distribution applied to both feet of the golfer or the impact force applied to the golf shoes while the golfer is moving.

When describing the method of measuring the green with the green measuring device 500 of the present invention, first, the golfer attaches the green measuring sensor module 520 to the golf shoe using Velcro, and then attaches the shoe insole to which the weight sensing module 540 is attached. Install on golf shoes.

Next, in order to execute the ninth step (S9) menu, the green measurement sensor module 520 and the weight detection module 540 are operated to interwork with the mobile device so that the measured values of each module are transmitted and received data of the mobile device in real time It is transmitted to the advice generating unit 200 of the menu unit through the unit 112 and stored.

The advice generator 200 starts measuring the green based on the location and time at which the mobile device 110 and each module 520 and 540 are interlocked, and deletes and resets the measurement data recorded before that. Therefore, it is preferable for the golfer to link the mobile device 110 and the respective modules 520 and 540 at the point where the golf ball is located.

Next, in order to execute the tenth step (S10) menu, the golfer walks and moves from the golf ball position to the hole cup position based on the golf ball position. measure

In particular, a strong impact force is generated by stomping the green multiple times with both feet at the hole cup position so that the green measuring device 500 clearly recognizes the hole cup position. As a result, the acceleration sensor or the weight detection module 540 of the green measuring device 500 detects a strong impact force multiple times, and the advice generator 200 later recognizes the position where the impact force is stronger than other points as the hole cup position.

While the golfer walks, the green measurement sensor module 520 measures the inclination, movement distance, and movement direction of the green using a 3-axis acceleration sensor, a 3-axis gyro sensor for measuring angular velocity, a geomagnetic sensor, and a GPS sensor to measure the curvature of the green. information can be grasped.

For example, the distance between the golf ball and the hole cup may be calculated using the acceleration sensor measurement value received from the acceleration sensor of the green measurement sensor module 520 . The acceleration sensor measures the movement direction and acceleration of the golfer, and calculates information values of the movement distance and movement direction of the golfer based on the measured values. The information value of the moving distance and the moving direction using the measurement value of the acceleration sensor can be used alone or to supplement the calculation of the moving distance and the moving direction using the GPS sensor.

The gyro sensor measurement value measured in real time by the gyro sensor of the green measurement sensor module 520, that is, the amount of angular velocity change in the X, Y, and Z axes, and the acceleration sensor measurement value measured in real time by the acceleration sensor, that is, the amount of acceleration change in the X, Y, Z axes By continuously calculating the curvature between the golf ball position and the hole cup, it is possible to calculate the curvature information, which is continuous inclination information. In particular, the green measurement sensor module 520 converts the X, Y, Z-axis angular velocity change of the gyro sensor and the X, Y, Z-axis acceleration change of the gyro sensor into Roll, Pitch, and Yaw values to shake (translational motion) ) can be used to remove noise.

In addition, among the geomagnetic sensor measurement values received in real time from the geomagnetic sensor of the green measurement sensor module 520, the Z-axis change amount is compared with reference information for filtering the shaking noise, that is, the Z-axis change amount of the acceleration sensor measurement value and the gyro sensor measurement value value can be used.

The green measurement sensor module 520 may continuously sample the gyro sensor measurement value, the acceleration sensor measurement value, and the geomagnetic sensor measurement value at regular time intervals. It should be performed only with the measured value at the time of stepping on the green.

The time the golfer stepped on while walking on the green may be determined from the amount of impact detected from the acceleration sensor of the green measurement sensor module 520 and/or the weight detection value or weight distribution of the weight detection module 540 of the golf shoe insole, and the golfer The position (hereinafter referred to as "walking point") while walking can be grasped from the information value of the moving distance and moving direction at the time point and/or the GPS sensor.

When the green measurement is performed in the tenth step (S10) through this process, as shown in FIG. 6 , the advice generating unit 200 grasps the movement path information of the golfer walking on the green, and the inclination of the green is determined at each walking point. Thus, the entire curvature information of the green can be collected.

In the green area, the slope information or green speed information of the position where the golfer does not walk is calculated by linear interpolation by applying the measurement values of each walking point, or information received from the course information database 141 of the server unit 120 is used. It can be calculated by using them together.

In particular, in the present invention, the property of green grass from the amount of impact applied to the golf shoe at the golfer's walking point using the impact amount detected from the acceleration sensor of the green measurement sensor module 520 and/or the weight detection module 540 of the golf shoe insole. In other words, it is possible to grasp the degree of hardness or softness of the grass. It is very important to understand the speed characteristics of the green grass when putting because the golf ball speed is high when the green grass is hard and the golf ball speed is slow when the grass is soft.

In the present invention, the impact amount of the walking point and the speed characteristics of the green grass may be stored in the database in advance and stored in the course information database 141 of the server unit. The database related to the speed characteristics of the green grass is stored in the course information database 141 of each golf course in consideration of the impact amount, temperature, and humidity, and the effect of the grass type, etc., based on the standard weight of male and female golfers, In the eleventh step (S11), when the advice generating unit 200 performs the putting strategy information 230, it is transmitted to the mobile device and calculates a putting leader line indicating the putting distance and the putting direction. The speed characteristic of the green grass is weather information. can be considered as

The advice generating unit 200 of the present invention displays the putting guide line on the display unit 113 when performing the putting strategy information 230 of the eleventh step (S11), and, if necessary, to the golfer's walking as shown in FIG. 6 . The green curved line 660 expressing the inclination of the walking point formed along the grid in a grid shape is displayed on the display unit 113, or the green curved line 660 for the entire area where the golfer walked is displayed in a grid shape on the display unit 113. can be displayed in

In addition, when the putting address information 240 menu of step 13 (S13) is executed, when the golfer takes an address posture to align both feet toward the target point, it is necessary to take the weight balance of both feet differently depending on the inclination of the green. .

To this end, the advice generating unit 200 additionally executes a weight distribution measurement menu when the putting address information 240 menu is executed to operate the golf shoe insole weight detection module 540 and then the golf shoe insole weight detection module 540 ), the weight distribution of both feet detected by the display unit 113 may be displayed as a picture or a number.

Next, an operation process of the menu unit from the seventh step (S7) to the thirteenth step (S13) will be described with reference to FIG. 6 .

If the golf course currently being played by the golfer is green (G) and the golfer selects the putting strategy information 230 menu of the seventh step (S7), the menu unit uses the green measuring device of the eighth step (S8). The green measuring device use (231) menu asking for a question is displayed, and when the golfer selects the green measuring device use (231) menu, the green measuring device interlocking menu 232 of the ninth step (S9) is displayed.

Prior to selecting the green measuring device interlocking menu 232 in the ninth step (S9), the golfer installs the green measuring sensor module 520 and/or the weight sensing module 540 in the golf shoe and installs the sensor in the ninth step (S9). When the link menu is selected, the sensor modules of the green measurement sensor 500 are linked with the golfer's mobile device.

At this time, the golfer selects the green measuring device interlocking menu 232 of the ninth step (S9) and interlocks the green measuring sensor 500 with the golfer's mobile device at the point 600 where the golf ball is located on the green, so that the interlocking position is the measurement origin. make it this

Next, the golfer selects the green measurement mode 233 menu of the tenth step (S10), and then reciprocates several times on foot from the golf ball position 600 to the hole cup 640 position, but reciprocating around the hole cup 640 In order to collect as much measurement data as possible to determine the inclination of the green, in particular, to clearly grasp the position of the hole cup 640 , the impact force is increased by stomping both feet in the hole cup 640 .

When the golfer performs putting after completing the tenth step (S10), if the putting strategy information generation 234 menu is performed in the eleventh step (S11), the advice generating unit 200 measures the measured value of the green measuring device A curved line 660 drawn on the display unit 113 by collecting course information of the field and server unit, a putting guide line 620 indicating a putting distance and a putting direction, a target point 630, and a deflection distance 650 with the hole cup ), for example, 2 cups on the right side.

For example, when the green has an uphill slope to the right based on the hole cup, the advice generating unit 200 reflects the right uphill slope of the target point 630 to be actually putt to the right side of the actual hole cup. Calculate how much bias you need to putt. The actual putting direction and deflection distance may be calculated using a reference table or formula in consideration of green speed, hole cup distance, and the like. If, as a result of the calculation of the advice generating unit 200, the target point 630 is calculated to be biased to putt to a distance corresponding to about 2 cups to the right of the actual hole cup, the display unit 113 displays '2 cups on the right' or ' Deflection distance of 22cm' is indicated to the right. Here, the deflection value of the right 2 cups is the distance from the end of the hole cup to the right assuming there are two hole cups (generally 1 cup = about 10.8 cm).

When the golfer performs the putting strategy information generation 234 menu to take an address posture while familiar with the target point 630, the putting address information 240 menu of the 13th step (S13) is selected. At this time, the golfer directs the mobile device toward the golfer's golf shoes and golf ball so that the advice generating unit 200 identifies the foot alignment line 610 and the golf ball alignment line 700 and displays it on the display unit 113 .

In addition, in the thirteenth step ( S13 ), the advice generating unit 200 may display the weight distribution of both feet detected by the weight sensing module 540 of the golf shoe insole as a picture or a number on the display unit 113 .

7 is an example showing the display unit 113 when the putting address information 240 menu of the eleventh step (S11) is selected.

When the present invention performs the menu operation process from the seventh step (S7) to the thirteenth step (S13), the display unit 113 of the mobile device displays the feet alignment line 610 and the putting instruction line 620 with the golfer as the center. ), the golf ball alignment line 700 and the corresponding azimuth may be displayed, and also the weight distribution of both feet may be displayed as a percentage number.

Therefore, the golfer adjusts the position of both feet while looking at the display unit 113 of the mobile device so that the foot alignment line 610 is parallel to the putting instruction line 620, and the golf ball alignment line 700 is also the putting instruction line 620. to match with At this time, the golfer may also adjust the weight balance of both feet while looking at the display unit 113 .

As described above, the present invention has the effect of presenting a course attack method optimized for each individual in consideration of the golfer's skill, etc. by using the user database 142 of the server unit 120 that stores the golfer's past play records Also, the mobile device 110 displays the target leader line presented in the course attack method and the golfer's foot alignment line on the display unit 113 using the AR (Augmented Reality) function, so that the golfer can see the difference between the foot alignment position and the target leader line. It has the effect of correcting the address posture or alignment direction of the golfer to match the optimal course strategy information by making corrections while visually grasping it.

In addition, the present invention has an effect of reducing mistakes in putting by providing the putting strategy information suitable for the actual green situation by the golfer measuring the slope or the green speed of the green with the green measuring device 500 .

Next, when a golfer is positioned on an inclined fairway through FIGS. 8 and 9 , a description will be given of adjusting the alignment direction of both feet by using a foot measuring device and an earphone without using the camera function of the mobile device.

When the golfer is positioned on an inclined fairway as shown in FIG. 8 , the golf ball returns to the target position due to the inclination of the fairway even if the golfer's feet are aligned parallel to the target indicator line 300 provided in the course attack information of the sixth step ( S6 ). may not be able to reach In order to solve this problem, golfers generally adjust the alignment line of both feet to have a deviation from their intended hitting direction according to the inclination of the fairway so that the golf ball reaches the intended target position. However, with the conventional method, it is difficult for novice golfers to use the conventional method, as it is difficult for novice golfers to use the conventional method because it is only empirically that the alignment line of both feet needs to deviate from the intended hitting direction according to the inclination of the fairway. There was a problem in that it was not possible to accurately grasp the amount of deviation between the alignment line and the intended hitting direction.

In the present invention, in order to solve the conventional problem, the alignment direction of both feet is adjusted by using a device for measuring both feet and an earphone. For this purpose, a menu as shown in FIG. 9 is separately added.

First, when the golfer selects the course game information 210 menu in the sixth step (S6), the advice generator 200 obtains the golfer's location information obtained in the third step (S3) and the fourth step (S4) By referring to situation information such as green location information, par information, slope, bunker location information, hazard location information, hole cup location information, etc. of the corresponding course, and also information provided by the user database 142 of the database 140, Create course availability information to provide to golfers.

Next, in step 601 (S601), when the menu of using the both feet measuring device 211 is selected, the golfer attaches the same green measuring sensor module 520 as the green measuring device 500 to the golf shoe by attaching the Velcro to the golf shoe. It is attached by using and the shoe insole to which the weight sensing module 540 is attached is installed on the golf shoe.

In step 602 (S602), if the menu of interlocking the two feet measuring device 212 is selected, the green measuring sensor module 520 and the weight sensing module 540 are operated to interlock with the mobile device so that the measured values of each module are displayed in real time. It is transmitted to and stored in the mobile device 110 through the data transceiver 112 of the mobile device.

The advice generating unit 200 starts to measure both feet based on the position and time at which the mobile device 110 and each module 520 , 540 are interlocked, and deletes and resets the measurement data recorded before that. Accordingly, it is preferable for the golfer to link the mobile device 110 and each module 520 , 540 in a position to take an address posture on the fairway.

Next, when the address information 220 menu is executed in step 603 ( S603 ), the foot measuring device 800 measures the position of the feet based on the time and location interlocked with the mobile device 110 .

In this step, the fairway slope information obtained in the sixth step (S6), the personal skill information of the user database 142, the hole cup location information, and the target location information are already stored in the mobile device, and the golfer needs to hit the golf ball. Since the target leader line 300 indicating the direction and its azimuth are calculated, the difference between the azimuth angle of the alignment line of both feet and the azimuth angle of the target leader line 300 can be determined based on this information and the measured value of the foot measuring device 800 ( see Fig. 8).

Since the angle of deviation that determines how many degrees the alignment line of both feet is to deviate from the target leader line 300 varies depending on the inclination of the fairway, the angle of deviation between the alignment line of both feet and the target leader line 300 and the relationship between the inclination of the fairway are in the table in advance. It can be stored or calculated by the simulation model, and when the table or simulation model is stored in the server unit 120 or stored in advance in the mobile device and the address information 220 menu of the advice generator 200 is executed, The angle of deviation between the alignment line of both feet and the target leader line 300 is determined by calling from the table or performing the simulation model.

When the address information 220 menu is executed, the angle of deviation between the alignment line of both feet and the target leader line 300 obtained from the table or the simulation model is called “target deviation angle”, and both feet are measured when the address information 240 menu is executed The difference between the azimuth angle of the alignment line of both feet measured by the device 800 and the azimuth angle of the target leader line 300 is referred to as a “foot deviation angle”.

Next, the advice generating unit 200 calculates the difference between the already recognized azimuth angle of the target leader line 300 and the azimuth angle of the alignment line of both feet to determine the current “balance angle of both feet”.

Next, the advice generating unit 200 calculates a difference (hereinafter referred to as “error angle”) between the “target deviation angle” obtained from the table or the simulation model and the measured “deviation angle of both feet”.

Thereafter, the advice generating unit 200 converts the “error angle”, which is the difference between the “target deviation angle” and the measured “balance angle of both feet”, into a voice and transmits it to the earphone.

In step 603 (S603), the golfer can grasp the error angle with the earphone with the earphone while holding the golf club in both hands. (300) can be easily matched with the “target deviation angle” that deviates from it.

On the other hand, when performing step 603 (S603), the weight distribution of the golfer on both feet is measured from the weight sensing module 540 of the both feet measuring device 800 and notified through the earphone, so that the golfer can easily control the weight distribution of the left and right feet. have.

Next, when the golfer is positioned on the green through FIGS. 10 and 11, the adjustment of the alignment direction of both feet to be parallel to the putting line by using the foot measuring device and earphone without using the camera function of the mobile device will be described.

At this time, since the green map including the putting leader line 620 is displayed on the display unit 113 , the golfer adjusts the direction of the golf ball alignment line so that the golf ball alignment line coincides with the putting instruction line 620 .

Next, in the 122nd step (S122), when the use of both feet measuring device 236 menu is selected, the golfer attaches the same green measuring sensor module 520 as the green measuring device 500 to the golfer using the Velcro to the golf shoe. It is attached by using and the shoe insole to which the weight sensing module 540 is attached is installed on the golf shoe.

In step 123 ( S123 ), if the menu of interlocking both feet measuring device 237 is selected, the green measuring sensor module 520 and the weight sensing module 540 are operated to interlock with the mobile device so that the measured values of each module are displayed in real time. It is transmitted to and stored in the mobile device 110 through the data transceiver 112 of the mobile device.

The advice generating unit 200 starts to measure both feet based on the position and time at which the mobile device 110 and each module 520 , 540 are interlocked, and deletes and resets the measurement data recorded before that.

Therefore, it is preferable for the golfer to link the mobile device 110 and each module 520 and 540 at a position where they putt on the green.

Next, when the putting address information 240 menu is executed in step 124 ( S124 ), the foot measuring device 800 measures the position of both feet based on the time and location interlocked with the mobile device 110 .
