Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing analyzing device capable of correcting a swing posture and allowing a game to be performed, and a swing analyzing device capable of correcting a swing posture,

The present invention relates to a swing analysis device and a method of operating the swing analysis device, and more particularly, to a swing analysis device capable of correcting a swing posture and a game method. More specifically, It is about a technique that makes it possible to maintain an optimal swing posture in an actual game.

In sports such as golf, baseball, basketball, tennis and table tennis, practice swing, also called image training, is the most basic training method for improving your skills. For professional athletes, spend a lot of time on the practice swing when hitting the actual ball and maintaining a swing-free swing posture in a live game.

On the other hand, during the practice swing, when there is a ball and when there is no ball, the swing position changes unconsciously. That is, when there is no ball, the natural swing tempo and posture are maintained in a relatively comfortable state. However, if there is a ball, the swing tempo is unconsciously accelerated and the unnecessary parts such as upper body, arm, and hand are pressed. Therefore, the result of ball direction or distance is not good.

Also, when comparing the practice swing without specifying a specific rule and the actual game (game) based on the rules, the difference in the swing tempo and the posture is caused by the difference in the degree of tension. Not only golf, but also other sports such as soccer and billiards, it is because of tension that it is often the case that mistakes that are not made in practice often come out of practice.

On the other hand, ordinary people who do not have common sense about exercise posture imitate the posture of professional players. For example, when playing on a golf course or trying to practice a swing alone, there is no accurate information about his / her swing posture, so he uses his swing posture to correct his swing posture. However, when correcting the swing posture in this manner, it is difficult to learn the accurate swing posture because the swing posture must be corrected depending on the subjective judgment of the user.

Also, even if you practice swing while watching a book or video, it may not fit your posture. In other words, there is basically a common swing posture, but there is also a need to fine posture according to the human body. Therefore, if you ignore your career or physical condition and follow a professional athlete's posture or if you follow a formal posture, you will not be able to improve your ability and your posture will be difficult to correct due to your body's habits.

Therefore, it is necessary to be able to carry out the same optimum attitude of the user, which is acquired through practice, in actual situation, and a program or equipment to support this is desperately needed.

On the other hand, a conventional technology that supports the analysis and correction of the swing attitude of the user is the Korean Utility Model No. 20-0417280 (May, 19, 2006, "swing posture correcting device").

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems of the prior art as described above, and it is an object of the present invention to collect and analyze swing data of a user so that when the ball is present and when there is no ball, The present invention has been made to provide a technique for enabling the user to correct the swing posture by himself / herself, and to feel the fun and to double the effect of the exercise.

According to an aspect of the present invention, there is provided a swing analysis apparatus capable of correcting a swing posture and playing a game, comprising: a sensor module unit for collecting swing data attached to a body or a tool of a user and sending a signal; A main body for analyzing swing data received from the sensor module according to a set mode; And a database unit for storing the swing data and the analyzed result, wherein the main body comprises: a data receiving unit for receiving the swing data from the sensor module unit; A data analyzer for processing, processing and analyzing the received swing data; A simulation processor for simulating a virtual ball movement analyzed based on the swing data; And a display unit for outputting a comparison analysis result analyzed for each mode by the data analysis unit and virtual simulated moving data simulated by the simulation processing unit.

Here, the data analyzer of the main body automatically discriminates a mode through a signal that the sensor module unit is in a stop state and a rapid swing speed change of the sensor module unit. When the stop state of the sensor module unit is less than a predetermined time, And if the swing speed is not abruptly changed, the swing speed is judged to be a ball-less exercise mode. If the swing speed is suddenly changed after the stopping state of the sensor module is within a predetermined time, A swing is performed after the stopping state of the sensor module unit exceeds a predetermined time, and if the swing speed does not change suddenly, it is determined that the game mode is ball-free, and after the stopping state of the sensor module unit exceeds a predetermined time, If there is a sudden change in the swing speed, Can.

In addition, the swing data of the user's ideal swing posture is stored in the database unit, and after the data analysis unit determines that the ball simulation mode, the ball practice mode, the ballless game mode, or the ball game mode is completed When the user performs the swing, the swing data is transmitted from the sensor module unit to the main body. When the data receiving unit of the main body receives the swing data, the data analyzing unit processes and analyzes the swing data, The swing data of the user's ideal swing posture and the current swing data are compared and analyzed to output data including numerical values.

The hitting sensor may further include a distance sensor and a striking member. The field sensor may include a distance sensor and a striking member, The distance detection sensor detects the distance to the hitting position notification board, and when the tool reaches a predetermined position in front of the hitting position reporting board, the hitting member hits the tool and notifies the user of actual hitting feeling Can be given.

According to another aspect of the present invention, there is provided a method of operating a swing analyzer capable of correcting a swing posture and playing a game, the method comprising: (a) setting a swing mode in a data analyzer of a main body; (B) collecting swing data from the sensor module unit and transmitting the swing data to the main body when the swing of the user is performed; (C) processing and processing the swing data in a data analysis unit of the main body and analyzing the swing data; (D) simulating the ball movement analyzed on the basis of the swing data in the simulation processing unit of the main body; (E) outputting a comparison analysis result analyzed for each mode by the data analysis unit and virtual simulated moving data simulated by the simulation processing unit through a display unit; And (f) storing the swing data and the simulation result in a database unit.

In the step (a), a mode is automatically determined based on a signal indicating that the sensor module unit is in a stop state and a rapid swing speed change of the sensor module unit. When the stop state of the sensor module unit is less than a predetermined time, And if there is a sudden change in the swing speed, it is determined that the swing speed has not changed suddenly. If the swing speed is suddenly changed, A swing is performed after the stopping state of the sensor module unit exceeds a predetermined time, and if there is no sudden change of the swing speed, it is determined that the game mode is the ballless game mode, and when the stopping state of the sensor module unit exceeds a predetermined time Swing is performed, and if there is a sudden change in the swing speed, it can be determined that the game mode is the ball mode.

The swing data of the user's ideal swing posture is stored in the database unit. In step (e), the swing data of the user's ideal swing posture is compared with the current swing data, Can be output.

The present invention has the following effects.

First, when the user performs a swing in various situations, the swing data is analyzed and the result is outputted, and it is possible to correct after confirming how the posture is disturbed and the tempo changes in each situation. In golf, for example, you can maintain a smooth swing, tempo, and in-in swing trajectory when you practice swing without hitting the ball, but when you practice with the ball, the swing tempo increases faster without you knowing, The variation of the direction and distance of the ball is increased, and the balls are irregularly generated. In particular, in a practice game in which a game is to be taught or a record is to be achieved based on a specific rule, the degree of tension is increased and the posture becomes more disturbed. In the present invention, swing data And then outputting the comparison data by numerical value, chart, image, sound, etc., so that the swing tempo and posture of each situation can be immediately confirmed and the posture can be corrected by oneself. In other words, regardless of whether the ball is actually hit or whether it is a practice or an actual game, it can help to maintain a consistent tempo and attitude at all times.

You can also review your swing data at any time. In other words, since the swing data stored in the database unit can be viewed on a mobile or a PC, the user can continuously develop his / her skills regardless of time and place.

The swing-requiring exercise may be golf, baseball, tennis, squash, bowling, table tennis, dart, badminton, or billiard. Hereinafter, golf is exemplified.

FIG. 1 is a conceptual diagram for explaining a swing analysis apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram for explaining a swing analysis apparatus shown in FIG.

1 and 2, the swing analysis apparatus according to the embodiment of the present invention mainly includes a sensor module unit 100, a main body 200, and a database unit 300.

The sensor module unit 100 is provided for collecting swing data by sensing the user's attitude by attaching to the user's body or tool. The sensor module unit 100 includes a sensor unit 110 including an acceleration sensor 111, a gyro sensor 112 and a geomagnetic sensor 113 and a data transmission unit 110 for transmitting the collected swing data to the main body 200 (120).

The sensor module unit 100 further includes a key input unit 114 for receiving a user command such as whether to perform a swing. That is, when the key input unit 114 is operated, the data transfer unit 120 sends a signal to the main body 200 to prepare the main body 200 to receive the swing data collected by the sensor module unit 100 You can.

The sensor module unit 100 is provided with a hook-shaped module coupling unit 130 formed of a plastic material. The sensor module unit 100 can be swung through the module coupling unit 130, Is easily detachable. Of course, the module coupling part 130 for mounting the sensor module part 100 to a tool or a body can be modified into various forms such as a clip, a rubber belt, or a Velcro.

The sensor unit 110 includes an acceleration sensor 111, a gyro sensor 112 and a geomagnetism sensor 113. The sensors sense a user's swing in a three-dimensional space and determine a swing speed, a swing locus, ), Swing data such as an angle formed by the golf club and the ball when hit, a swing tempo, and the like are measured.

Each of the sensors 111, 112, and 113 of the sensor unit 110 tracks the position of an arbitrary point along the swing of the user on a three-dimensional space using sensors belonging to the MEMS (Micro Electro Mechanical System) field. The acceleration sensor 111 senses the velocity of the golf club when the user performs a swing and the gyro sensor 112 measures the angular velocity of the golf club to measure a change in the azimuth of the object. And the geomagnetic sensor 113 detects the direction of the magnetic field generated by the earth and detects the direction of the geomagnetic sensor 113. The sensor detects the direction of the swing by moving the position of the user's cuff. The manner in which these sensors sense motion is well known in the art, so a detailed description thereof will be omitted.

The data transfer unit 120 transfers the swing data of the user, which is collected by the sensor unit 110 and processed by the digital signal or the electrical signal, to the main body 200.

The main body 200 is provided for analyzing the swing data of the user received from the sensor module unit 100 according to the set mode and simulating the swing data to show the movement trajectory of the hit ball to the user. The main body 200 includes a data receiving unit 210, a data analyzing unit 220, a simulation processing unit 230, a display unit 240, and a game operating unit 250. Here, each of the components of the main body 200 may be integrally formed, but the display unit 240 may be separately provided, and the remaining components may be formed in the form of a pad or a set-top box and connected to the display unit 240.

The data receiving unit 210 is provided to receive the swing data transmitted from the sensor module unit 100.

The data analyzer 220 is provided for analyzing the swing data received by the data receiver 210. For example, the data analyzer 220 analyzes the angle of the golf club and the swing trajectory for each swing performed by the user in various directions by dividing the swing by the interval. That is, a plurality of positions of the golf clubs at the time of hitting are extracted by one point, and the swing trajectory is analyzed. The swing is divided into an in-swing, an in-out swing and an out-in swing, The motion trajectory of the ball is comprehensively determined.

On the other hand, the data analysis unit 220 may determine whether the currently executed swing is a swing in a certain mode (mode) by analyzing the swing data. The situation (mode) that can be given can be classified into a swing when there is no view, a swing when there is a ball, a practice mode, or an actual game mode. Of course, each state (mode) may be set according to the command input of the user, but the data analysis unit 220 may analyze the swing data and automatically determine the swing data. The description will be described later.

The simulation processing unit 230 calculates and simulates the movement trajectory of the hit ball based on the swing data of the user analyzed by the data analysis unit 220. That is, according to the analysis result of the data analysis unit 220, when the user hits the ball, the moving speed of the user's cuff, the swing speed of the golf club, the initial moving direction of the golf ball due to the angle of the golf club, ), The simulation processing unit 230 finally simulates the distance traveled by the ball.

The display unit 240 outputs a simulation result of the swing data of the user on the screen of the simulation processing unit 230. As described above, the display unit 240 may be embedded in the main body 200, but may be connected to a display device such as a separate monitor or a TV by wire or wireless.

The database unit 300 is provided to store swing data collected by the user in various setting modes or to store the result of analyzing the swing data. In addition, the main body 200 may load swing data stored in the database unit 300 when necessary. In addition, the data stored in the database unit 300 may be remotely downloaded by the user. Meanwhile, the database unit 300 may be embedded in the main body 200, but may be separately provided and connected to the main body 200 through a network.

The game operation unit 250 will be described below again.

The swing analyzing apparatus according to the embodiment of the present invention described above will be further detailed by a method of operating the swing analyzing apparatus described below with reference to FIG.

3 is a flowchart illustrating a method of operating the swing analysis apparatus according to an embodiment of the present invention. That is, the present invention relates to a process of allowing a user to perform a posture correction by analyzing a swing in various modes using the swing analysis apparatus shown in FIGS. 1 and 2 and outputting the swing analysis result.

First, the user turns on the power of the swing analysis apparatus and selects a swing mode through a key input unit provided on the sensor module unit 100 or a setting button (not shown) provided on the main body 200, and swings in various modes >. Of course, the swing mode setting may be determined according to a specific algorithm in the main body 200 even if the user does not separately input a command, and each example will be described in detail below.

The swing mode can be classified into four types according to whether there is a ball and whether it is an exercise or an actual practice. That is, it can be a ballless practice mode, a ball practice mode, a ballless game mode, and a ball game mode.

Normally, when there is no ball, the natural swing tempo and posture are maintained in a relaxed state. However, when there is a ball, the swing tempo is unconsciously accelerated, and the swinging posture is often disturbed due to force in unnecessary portions. Therefore, it is necessary to make a comparative analysis according to presence or absence of a ball, so that different modes are provided.

In addition, it is possible to maintain correct attitude in practice situations in which certain rules or records are meaningless to achieve, but in practice games in which a rule is required to cover a game or achieve a record, tension often becomes extreme and the posture is often disturbed. Therefore, a comparative analysis according to whether it is a practice game or an actual game is also needed, so that each mode is different.

When the user swings according to each swing mode, the data transmission unit 120 of the sensor module unit 100 transmits the swing data collected by the sensor unit 110 to the main body 200 (S20) The data analyzing unit 220 analyzes the swing data at the data receiving unit 210 of the controller 200 and calculates the trajectory of the ball at step S30 and the simulation processing unit 230 performs a simulation process S40, The simulation result is output to the display unit 240 < S50 >. The swing data analyzed by the data analysis unit 220 and the simulation results derived from the simulation processing unit 230 may be stored in the database unit 300.

Here, the user swings in each mode, and if the ball is considered to be the most ideal posture to judge himself or when the distance of the ball is recorded at the maximum, the user can press the setting button 114 of the key input unit 114 or the main body 200 The swing data and the analysis result for the swing posture can be separately stored in the database unit 300 and set to the role model swing posture. Accordingly, the swing data set by the user and the swing data set by the role model are output together through the display unit 240, thereby confirming how the swing posture of the user has collapsed.

Of course, if the swing is repeated several times without separately setting the roll model swing postures, the data analysis unit 220 automatically compares the swing data with the ball distance to automatically update the ideal swing posture, It is also possible to compare and analyze with automatic update contents. That is, the data analyzer 220 analyzes the swing data of the user, stores the swing posture analyzed as the most ideal swing posture in the database unit 300, loads the swing posture as needed, and uses it for comparison analysis.

An example of setting or automatically determining the swing mode will be described below.

As a first method, the mode is controlled by using the operation of the key input unit 114 attached to the sensor module unit 100, the operation of a button (not shown) of the main body 200, or the UI output from the display unit 240 By selecting, the main body 200 can determine which mode the user is currently swinging in. For example, if any one of the ball-less practice mode, the ball practice mode, the ball-less game mode, and the ball game mode is set through the key input unit 114, the data transfer unit 120 transmits a signal for the selected mode to the main body 200 The data analyzer 220 analyzes the swing data received from the sensor module 100 according to the set mode.

In the second method, the main body 200 determines a swing mode through a stop state signal sent from the sensor module unit 100. That is, if the user swings without stopping in the address (preparation or alignment) process before the swing, the data analysis unit 220 of the main body 200 determines that the golf mode is the ballless exercise mode, If the club is stopped, it is judged to be a practice mode, and if it is stopped for 5 seconds or longer, the game mode is determined. In the ballless practice mode, you do not have to hurt yourself and you only need to worry about your posture, so you do not need an addressing process, so you can swing quickly. On the other hand, in the practice mode with a view, a relatively long addressing process is required because the ball needs to be precisely aligned even in the practice situation. However, in an actual game, a longer addressing process is required, since the direction and the force must be adjusted apart from the presence or absence of the ball. With this feature, the data analyzer 220 can automatically determine the swing mode according to the swing preparation time. Of course, the setting of the reference time for the stop state for automatically determining whether the data analyzing unit 220 is a ball game or an exercise or a game can be adjusted according to the characteristics of the sports item.

As a third method, the data analysis unit 220 of the main body 200 can determine whether the swing is performed in the state where the user hits the actual ball when the swing is performed or the ball is swung without the ball, have. The graph of FIG. 4 is a comparison of the swing data in the state in which there is no ball and the swing data in the case of actually hitting the ball. The x-axis is the number of samples for the posture that occurs until the swing is completed by the swing, and the y-axis is the swing phase velocity.

As shown in FIG. 4, there is a difference between the swing data when the user hits the ball and the swing data when there is no ball. In other words, the golf club does not show a rapid change near the maximum speed because the user does not hit the ball when there is no ball, but when the actual ball is hit, the golf club and the ball collide with each other, . Therefore, the data analyzer 220 analyzes the swing data to determine whether a sudden change in speed has occurred, thereby setting a swing mode to determine whether or not there is a ball.

Meanwhile, in the game mode, since the swing direction may be changed in order to change the moving direction of the ball according to the game situation, it is necessary to correct the angle of the swing direction so that the main body 200 can recognize the swing direction. That is, although the user swings in a straight line, the ball may be bent sideways while being rotated, and accordingly, the user may intentionally swing the ball to move the ball to the target position. Accordingly, if the swing direction of the user changes, the sensor module unit 100 senses the swing direction and corrects the angle so as to be equal to the swing direction of the user in the virtual game, thereby moving the ball to the target.

If the direction of the user's first swing is 0 and the ball is in the forward direction, then swinging in the forward direction requires a reference point for calculating how many turns the ball is rotating in the forward direction. This means that when the swing direction is 0 degree, . Therefore, several methods can be implemented for the sensor module unit 100 to detect this.

First, address the direction of the golf club once in the direction of 0 degrees at first. The user places the golf club in the stopped state for about 2 seconds to 5 seconds or presses the key input unit 114 to recognize the addressed position of the current golf club in the direction of 0 degrees and stores the position in the sensor module unit 100 or the main body 200 . Then, when the user swings the swing direction, the gyro sensor 113 detects the rotation of the golf club, so that the angle is calculated based on the direction in which the golf club is first addressed, The direction of the hole is corrected. At this time, it is possible to inform the user that the angle is changed by giving a vibration to the sensor module unit 100 or by the LED provided in the sensor module unit 100, or by displaying an image such as 'Ready' You can tell. Then, if the user turns the direction of the golf club in the desired direction by adjusting the left and right directions, it is possible to notify the sensor module unit 100 of LED, sound and vibration in real time, You can tell them by image or number. Therefore, 0 degree is set at the initial setting, so if you want to set the wrong direction back to 0 degree, you should go through the above process again.

Second, address the direction of the golf club every 0 swings. The user turns the golf club at a desired angle and stops the golf club for about 2 seconds to 5 seconds or presses the key input unit 114 to recognize the current address of the golf club in the direction of 0 degree and then the sensor module 100 or And stored in the main body 200. At this time, how much the angle of the golf club is changed than the previous angle can be informed by the display unit 240 in real time. Thereafter, the sensor module 100 may be informed by vibrating the sensor module 100 that the sensor module 100 has been addressed to the user, or may be informed by the LED provided in the sensor module 100, or may be displayed on the sound or display unit 240 as 'Ready' You can tell. Therefore, even if the user intentionally performs the swing in a straight line without performing the swing in a straight line, in the virtual game, the ball is automatically shifted by the user's intended angle to move the ball. In particular, this will be effective when playing with a large number of people.

Third, the direction is determined by comparing the trajectory of the section where the golf club moves when the user swings, the golf club angle and the swing direction at the time of hitting, without comparing with the existing swing data. That is, in the virtual game, when the user hits the virtual ball, the player detects the lowest point and the highest velocity of the swing and detects the force transmitted to the ball, the swing trajectory, the golf club angle and the swing direction, To determine the movement of the ball.

In more detail, the ball may be rotated by the user depending on the swing trajectory and the angle between the ball and the club when the ball is hit by the user, and the ball is driven by the force according to the velocity of the golf club applied to the ball. Will be different. The moving direction of the ball is determined by comparing the swing data thus performed with the swing data performed in the existing virtual game. For example, if the swing performed by the user in the current virtual game is performed by shifting by 10 degrees compared to the previous swing, the golf club speed and angle and swing trajectory are applied in the same manner based on the previous swing data, It is determined that the direction of movement of the ball is wrong.

Alternatively, when the ball is hit in the virtual game, the sensor unit 110 compares the magnitude of the impact, the magnitude of the vibration, and the direction of the impact with the swing data stored in the database unit 300 to determine movement of the hit ball .

Here, the golf club may be equipped with additional equipment for allowing the user to feel a ball hit even if the ball is not actually placed in the practice mode or the game mode. That is, when the swing detecting unit 400 is mounted on the golf club shaft 700 together with the sensor module 100, when the swing is performed in the ball-less practice mode or the ball-less game mode, The golfer hits the golf club shaft 700 to feel as if the user hits the ball.

5, the hitting sensor 400 includes a distance sensing sensor 410, a striking member 420, a rotary member 430, a rotary pendant 440, a spring 450, and a motor (not shown) Is provided. In addition, a field position notification board 600, which is an object detected by the distance detection sensor 410, is provided in the field 500. Therefore, when the distance detection sensor 410 senses the distance to the hitting position notification board 600 in accordance with the user's swing step, when the golf club reaches a predetermined position in front of the hitting position notification board 600, By striking the club, the user is given the impression that he is actually hitting in the ball-less (practice, game) mode.

More specifically, when the distance detection sensor 410 detects that the distance detection sensor 410 has reached a predetermined position in front of the impact position notification board 600, the motor operates and the rotation latch 440 connected to the motor moves in the direction of the arrow . When the rotation clamp 440 is rotated, the rotation member 430 rotates about the rotation radius of the rotation clamp 440 and the rotation of the rotation member 430 causes the tension of the spring 450 to be overcome So that the striking member 420 coupled with the rotating member 430 is also rotated.

The spring 450 and the rotary member 430 are returned to their original positions by the restoring force of the spring 450 to release the engagement of the rotary member 430 and the rotary member 430, The striking member 420 combined with the striking member 420 strikes the golf club shaft 700 by the elastic force, so that the user can feel a hitting force even if the user does not hit the actual ball.

On the other hand, when the distance detection sensor 410 senses that the distance detection sensor 410 passes the batting position notification board 600, the operation is stopped, and then, when the swing is performed, the motor operates again.

In addition, the principle of operation of the distance sensor 410 may be operated in various ways, such as by using an ultrasonic wave. The configuration of the hitting sensor 400 may be configured such that if the purpose of giving the user the feeling of actual hitting is satisfied And can be implemented in various forms.

When the user sets a swing mode in which the swing is to be performed by the user or when the swing is performed by the user after the determination in the main body 200 is completed, the sensor module unit 100 collects the swing data of the user and transmits it to the main body 200 >. Here, the user's swing data includes various items. That is, the swinging posture of the user is classified in a stepwise manner in the three-dimensional space to collect items included in the swing data. In the golf swing, the swing posture is divided into eight steps of address-takeaway-backswing-backswing top-downswing-hit-follow-finish. At this time, the sensor module 100 calculates the swing angle, swing speed Various data according to the swing of the user such as the swing locus, the ball speed at the hit point, the position of the cuff, and the rotation of the golf club are collected and processed into a digital signal or an electrical signal to be sent to the main body 200, And the transfer unit 120 transfers the data to the main body 200.

Here, the swing data transmission between the sensor module unit 100 and the main body 200 may be performed using a short-range wireless communication scheme such as Bluetooth or a long-distance wireless communication scheme such as Wi-Fi.

When the data receiving unit 210 of the main body 200 receives the swing data from the sensor module unit 100, the data analyzing unit 220 analyzes the swing data. That is, since the maximum speed and the minimum height of the golf club are generated at the time of hitting when the user performs the swing, the swing speed of the golf club, the angle of the ball and the golf club, and the amount of impact indirectly applied to the sensor unit 110 Information on the entire swing interval of the user is calculated to calculate the trajectory of the ball, and the simulation processing unit performs simulation processing and outputs the information through the display unit 240. [ In addition, the data analysis unit 210 compares the swing data with the current swing data through the database unit 300, and outputs the analyzed swing data to the display unit 240. That is, the swing speed of the golf club, the angle of the golf club, and the movement trajectory of the initial ball at the time of impact are compared with the previous swing data before and after the golf ball hit by the user, and the result is shown by data such as numerical values, characters, tables and graphs.

In addition, the data analysis unit 210 can compare the swing tempo of the user and determine that the user's breathing is disturbed or the posture collapses due to the tense state during the swing. For example, in the ballless practice mode, the swing data is collected with a swing time of 0.2 seconds / 0.3 seconds and a swing time of 0.2 seconds / 0.4 seconds in the ball practice mode. Data is collected and can be collected in the game mode of viewing (0.15 seconds / 0.45 seconds). When the data thus compared and analyzed is outputted through the display unit 240, At which point the speed change has occurred.

Since the swing data for the user is stored in the database unit 300, it can be confirmed how much the correction of the golf swing posture has been performed according to the number of strokes and the amount of practice.

Here are some specific examples of swing data analysis.

The first is a comparative analysis of the swing angle of a golf club. As shown in FIG. 1, assuming that the swing posture of the right hand is assumed to be the swing posture, the ball is in a straight line with the target point, ). In this state, the user hits the ball at various angles, crossing the ball in and out with the hit area of the golf club. However, when the user performs a swing, an unintentional swing posture may occur.

A preferred golf swing posture is an in-in swing to generally maximize the distance of the ball in a straight and precise direction. The in-swing moves the golf club in the area before the golf club hit the ball, and the golf club moves in the area again after the hit. This in-swing moves the ball straight because the swing angle of the golf club is perpendicular to the straight line between the ball and the target when the golf club hits the ball. The sensor module unit 100 senses the swing angle of the golf club when the ball is struck, collects swing data of the user, and transmits the swing data to the main body 200 so that the swing data can be compared and analyzed.

Of course, since the user's arm swings bend inward to the user's body structure, the end of the movement trajectory of the ball can not but be bent into the inward area. Therefore, when the in-swing is properly performed, the ball moves in a straight line in general, and then bends slightly.

If this in-swing does not work properly, the ball may rotate without moving in a straight line. That is, if only the in-out swing is performed or only the out-in swing is performed, this means that the swing angle of the golf club hitting the ball is not perpendicular to the straight line with the ball and the target point, So that the ball is rotated and the target point is greatly deviated and the maximum distance of the ball can not be recorded.

In addition, if a user performs an in-out or in-out swing differently than an in-swing, it does not fly to the desired target point or the spin is over-applied and, if the user does not intend, And the distance is far.

The data analysis unit 220 compares and analyzes the swing angle of the golf club so that the user can send the ball with the maximum distance based on the swing data collected by the sensor module unit 100, I can tell you. That is, when the user performs an in-swing in the game mode, the sensor module unit 100 extracts the positions of the golf clubs at one swing step and connects them to one locus. The extraction and connection of these points are performed in the same manner in the practice mode, and finally, comparing with the in-swing in each mode, whether or not the swing is properly performed, or comparing the swing data or the role model swing data The data analysis unit 220 analyzes and notifies the user of the change.

In addition, the data analyzer 220 may compare and analyze how much the golf ball finally moves in the ball according to the swing angle of the golf club when various swings are intentionally performed by the user.

Second, a comparative analysis of the head-up phenomenon in which the user's head is rotated first in the swing posture is also possible. That is, the data analyzing unit 220 calculates the initial trajectory of the ball based on the hit ball point transmitted from the sensor module unit 100, and compares the initial trajectory of the ball with the roll model swing posture for the follow and finish steps, This is a comparative analysis of whether the head is rotated before the golf club.

However, if the user's posture is wrong, the golf club can be rotated without following the follow-up and finish steps. As a result, the whole body floats, and instead of striking the center part of the ball, it hits the upper part, so the ball does not float but moves and moves. Therefore, the data analysis unit 220 calculates the initial trajectory of the ball based on the hit ball point transmitted by the sensor module unit 100, and compares the initial trajectory of the ball with the swing posture in which the follow and finish steps are performed properly, It can be compared to see if it was rotated before the club. For example, if the swing data in the game mode is compared with the swing data in the practice mode and the swing trajectory in the game mode is positioned 1 cm above the middle point of the ball in comparison with the swing trajectory in the practice mode, The sudden upward movement of the swing trajectory indicates that the user has headed up.

Thirdly, it is possible to compare and analyze the swing speed of the golf club and the impact amount (swing power) of the ball when hit. This swing speed and the amount of impact that the ball receives during the impact (impact) allows the user to know the accuracy of the swing. That is, the impact and direction of the ball are different according to the swing speed of the user, the impact amount of the ball when the impact is applied, and the impact of the sweet spot, the toe, and the heel of the head at impact. Therefore, the data analysis unit 220 can compare the swing mode with the current swing mode by comparing the swing data with the most ideal swing data at the present time point, and can notify which of the swing modes has been disturbed. For example, if the user was able to send the ball up to 5m / s swing speed, then when swinging at 6m / s, compared to the roll model swing data or the most ideal swing data at this time, And may be analyzed by the data analysis unit 220.

Fourth, comparative analysis of iron shots is possible. An iron is a golf club to float a ball. When performing an iron shot, the user compares the position of the lowest point of the swing trajectory with the position of the ball so that the hit point is positioned ahead of the ball. The iron swing of this down blow swing naturally floats the ball and the user can record the maximum distance of the iron shot. With the wrong swing, however, the user may be forced to perform an upper blow swing, which will purposely raise the bottom of the ball to force the ball. Therefore, the sensor module unit 100 calculates the entire trajectory that the ball moves on the basis of the initial trajectory of the ball, the swing trajectory, and the angle of the swing shaft at the impact time, analyzes the swing pattern, and calculates the roll model swing data and the most ideal swing data In comparison with an iron shot, thereby inducing a practicing down blow swing.

The comparison analysis items are performed comprehensively when the user performs the swing. In the present invention, the data analyzer 220 compares and analyzes the user's posture based on various other items. Finally, based on the comprehensive comparison analysis, the trajectory of the ball is calculated and the posture of the user is compared with the stored swing data.

The simulation processing unit 230 simulates the trajectory of the ball calculated and calculated to finally derive the ball movement, and compares it with the swing data stored in the database and displays it (S40). In addition, the simulation processing unit 230 also simulates and schemes a secondary motion such as a ball colliding with another object in a virtual game or falling into a bunker according to the movement of the ball.

The display unit 240 outputs (S50) the swing data comparatively analyzed by the data analysis unit 220 and the derived simulation results so that the user can visually confirm the swing data. In this case, the swing data may be output automatically according to the intention of the user, or the swing data of each mode may be displayed automatically. Therefore, the user can correct the swing postures by comparing swing data for each mode shown on the display unit 240 by themselves.

Then, the swing data for the swing performed by the user is stored and stored in the database unit 300. The stored swing data is accumulated and can be loaded by the user whenever necessary.

Meanwhile, the simulation processor 230 not only schematically displays the swing posture and the ball movement on the display unit 240 after the user hits the ball, but also allows the user It is also possible to display the reaction of the user's action on the display unit 240 in synchronization with the movement of the user in real time using the 2D image or the 3D modeling data. Accordingly, the behavior of the user can be displayed on the display unit 240 in real time.

In addition, the data analyzing unit 220 can analyze the entire swing posture of the user by using a camera linked to the main body 200. This saves the user's swing step-by-step image frame and matches the previously stored role model swing posture or the current ideal swing posture and motion and compares and analyzes them. Accordingly, the user can check his / her swing state through the display unit 240 in real time, or can operate the main body 200 to capture the swing motion or view the replay image. In addition, since the user can confirm the swing data (text or graph) comparing and analyzing the swing step image and the swing image of the user, the user can analyze the problem of his / her swing attitude in three dimensions.

The process of virtual game progress in game mode will be described in more detail as follows. The virtual game is managed by the game operating unit 250 in the main body 200, and the entire process is shown on the display unit 240 for the user to check. Here, since the configuration of the game operating unit 250 is a technology already known in a screen golf apparatus or the like, a detailed description will be omitted.

First, the user presses the key input unit 114 or addresses the golf club in the game mode so that the game mode is set.

Next, the user specifies a field in which the virtual game is to be performed. That is, in the database unit 300, not only the domestic but also the world famous fields are stored, and the user designates a field to be played by the user. These fields can add various environmental factors according to the user's needs. In other words, you can add elements that can affect the movement trajectory of the ball, such as direction and intensity of the wind, and the state of the green.

Finally, we set the manner in which the game progresses. In other words, it can be set to be less than the usual 18 holes or less, the limit of the number of participants can be set, and the ranking selection method can be freely set.

The number of people participating here may be a large number of people, but an AI participates in the virtual game with the user. The difficulty level of AI can be selected by the user as beginner, intermediate or advanced.

The ranking selection method can be performed in various ways. For example, a plurality of users may perform a plurality of games rather than a single game, and may select ranking based on the prize money earned.

If the ranking is finally selected after the user proceeds the virtual game, the record at this time is stored in the database unit 300 and can be continuously checked by the user. The swing data related to the swing attitude of the user performed in the virtual game is compared with the swing data performed in the practice mode in the course of the virtual game in the data analysis unit 220 as described above, 230 simulate the movement trajectory of the ball, and the sweep data of the comparative analysis and the movement trajectory of the simulated ball are shown on the display unit 240. [

As described in detail above, when the user performs the swing in various situations using the swing analysis apparatus according to the present invention, the swing data is analyzed in the main body 200 and the result is output, It is possible to calibrate after checking whether there is a change in the tempo. In golf, for example, you can maintain a smooth swing, tempo, and in-in swing trajectory when you practice swing without hitting the ball, but when you practice with the ball, the swing tempo increases faster without you knowing, The variation of the direction and distance of the ball is increased, and the balls are irregularly generated. In particular, in a practice game in which a game is to be taught or a record is to be achieved based on a specific rule, the degree of tension is increased and the posture becomes more disturbed. In the present invention, swing data And then outputting the comparison data by numerical value, chart, image, sound, etc., so that the swing tempo and posture of each situation can be immediately confirmed and the posture can be corrected by oneself. In other words, regardless of whether the ball is actually hit or whether it is a practice or an actual game, it can help to maintain a consistent tempo and attitude at all times.

You can also review your swing data at any time. In other words, since the swing data stored in the database unit can be viewed on a mobile or a PC, the user can continuously develop his / her skills regardless of time and place.

In the meantime, the present invention is a device for providing information so that a user can calibrate his or her own exercise posture, and has described golf as an example of the device. However, as a field capable of analyzing a user's posture, Baseball, tennis, squash, bowling, table tennis, badminton, billiard, etc., and can be applied to various sports.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
