Description

Automatic aiming system using smart golf shoes

[0001] The present invention relates to an automatic aiming system using smart golf shoes, and more specifically, to an automatic aiming system using smart golf shoes that performs a function of assisting aiming so that the golfer can accurately address the ball in a state perpendicular to a line virtually connecting the target and the ball, while reflecting the stance preset by each golfer to assist aiming suited to the address characteristics of the golfer, automatically determines the quality of the ball based on the landing position, calculates a correction value reflecting the quality of the ball and the lie of the swing position and the type of club, and applies it to the aiming, and corrects the address through vibration of the left and right shoes so that other golfers cannot recognize it, thereby enabling quick and accurate aiming without disturbing the golfer's golf.

[0002] As is well known, the most important thing in golf is to strike the golf ball and send it in the desired direction. To achieve this, aiming and addressing are performed. Aiming refers to the golfer drawing an imaginary line behind the golf ball toward the target, estimating the direction, while addressing refers to assuming the posture for the swing.

[0003] That is, before hitting the golf ball, position both feet and shoulders parallel to the imaginary line you aimed at, place the club on the ground behind the golf ball, and position yourself so that the hitting surface of the head is exactly perpendicular to the imaginary line.

[0004] In particular, when taking an address, if the position of both feet is not parallel to the aiming direction, the putter head will open or close, which will significantly change the direction of the golf ball, so it is very important to keep both feet parallel to the aiming direction.

[0005] However, when you address the ball and then slightly turn your head to check your target, you often experience an optical illusion where the actual imaginary line you saw behind the golf ball doesn't appear to be heading in the direction of the target. If you turn your head to look at the target while addressing the ball like this, you'll strangely see it more to the left or right of the target line, which can lead you to change your stance.

[0006] In other words, the position of both feet is not parallel to the aimed direction, which ultimately leads to a miss shot, and since there are many factors that affect the direction of the ball when actually hitting, such as the use of the wrists, the timing of the sequence between the torso and arms, in addition to the aiming, there was a problem in that it took quite a long time to realize that the cause of the miss shot was the aiming.

[0007] In particular, since the stance of each golfer is slightly different depending on the golfer's swing type, for example, some golfers stand in an open stance, some in a closed stance, and some in a standard stance, it cannot be said that addressing the ball perpendicular to the target is the correct aim.

[0008] Meanwhile, golf is a sport played with a partner, but it is also a sport where the swing is completely determined by individual ability, and since the tee-up time interval between teams is usually between 7 and 8 minutes, it is not an environment where one golfer can spend too much time aiming on the tee box or fairway, and if a lot of time is spent aiming, it is an act that puts a burden on the partner.

[0009] In the case of beginner golfers, it is not that they are clumsy in aiming at the target, but rather, even if they have accurate aiming, there are many cases where the result of the swing is not good due to mistakes that occur because the user's address alignment is not straight toward the aiming direction.

[0010] In particular, the alignment of the feet at address varies depending on the golfer's ball quality, but if this is not reflected and the alignment of the feet at address is followed by another golfer, the swing results are often poor even if the golfer has a good ball quality and a good club path.

[0011] In addition, there are quite a few golfers who have different swing characteristics for their driver swing and iron swing, that is, swings of iron clubs such as woods, utilities, and iron clubs. Taking this into consideration, corrections for aiming should be made, but there is a problem that there is no device that automatically performs such processing. Corrections that reflect trouble lies in the swing position should also be made, but there is also a problem that there is no device that automatically performs such processing.

[0012] The present invention has been made in consideration of the circumstances of the above-mentioned prior art, and basically performs the function of assisting aiming so that an address can be made accurately in a state perpendicular to a line virtually connecting a target and a ball, while assisting aiming suited to the address characteristics of the golfer by reflecting the stance set in advance by each golfer, automatically determining the quality of the ball according to the landing position, calculating a correction value reflecting the quality of the ball and the lie of the swing position and the type of club and applying it to the aiming, and enabling the address to be corrected through the vibration of the left and right shoes so that other companions cannot recognize it, thereby providing an automatic aiming system using smart golf shoes that enables quick and accurate aiming without disturbing the companions' golfing.

[0013] In order to achieve the above object, according to a preferred embodiment of the present invention, there is provided a smart golf shoe (2) comprising a signal input switch (6) for inputting an aiming request signal toward a target direction; a sensor module (8) for detecting an aiming direction and an address direction angle for the aiming direction according to an input of the signal input switch (6); a vibrator (14) provided on the inner bottom of the left and right shoes (2a, 2b) to generate vibrations so as to adjust the address direction angle for the aiming direction; a control unit (32) for calculating a user-specific address direction angle for an aiming direction to be transmitted through the smart golf shoe (2), detecting a current address direction angle of the corresponding user, and processing the result to adjust the address direction by comparing it with a set value; a memory (30) for storing the user-specific address direction angle for the aiming direction; a key input unit (26) for inputting a start signal for setting the user-specific address direction angle and a signal for completing the setting of the user-specific address direction angle; An automatic aiming system using smart golf shoes is provided, characterized in that it comprises a smart shoe management app (20) including a golf course map driving unit (34) that displays an aiming virtual line (A) connecting the current swing preparation point to the target landing point (TL) or the hole cup (Hole) at the request of the above control unit (32); and a correction value calculation unit (36) that determines whether the club to be swung is a driver or an iron club based on a judgment based on a previous swing position, identifies the actual golfer's ball quality based on the swing result value based on the previous swing position and landing position, calculates a correction value by applying the variables, calculates a corrected direction angle using the aiming virtual line as the target hitting line, and approves the calculated direction angle to the control unit (32).

[0014] Preferably, the control unit (32) controls to display a point that is a second shot or more and generates a signal requesting aiming as an actual landing point (RL), and controls to display an aiming virtual line (A) connecting the actual landing point (RL) to the next target landing point (TL) or hole cup (Hole), thereby providing an automatic aiming system using smart golf shoes.

[0034] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0035] FIG. 1 is a diagram illustrating a state in which a smart golf shoe, a ball, and a target are aligned in a straight line, included in an automatic aiming system using smart golf shoes according to an embodiment of the present invention, FIG. 2 is a diagram illustrating a configuration of a smart golf shoe included in the present invention, FIG. 3 is a diagram for explaining a direction detection principle of an automatic aiming system using smart golf shoes according to an embodiment of the present invention, FIGS. 4a, 4b, and 4c are diagrams for showing a state of setting individual address information through an automatic aiming system using smart golf shoes according to an embodiment of the present invention, FIG. 5 is a schematic diagram illustrating a structure of an automatic aiming system using smart golf shoes according to an embodiment of the present invention, FIG. 6 is a diagram illustrating a golf map in which an automatic aiming system using smart golf shoes according to an embodiment of the present invention is implemented and an automatic aiming processing principle thereof, and FIG. 7 is a block diagram illustrating a circuit configuration of an automatic aiming system using smart golf shoes according to an embodiment of the present invention.

[0036] With reference to this, a smart golf shoe according to an embodiment of the present invention basically performs a function of assisting aiming so that an address can be made accurately in a state perpendicular to a line virtually connecting a target and a ball, while assisting aiming suited to the address characteristics of the golfer by reflecting the stance set in advance by each golfer, automatically determining the quality of the ball according to the landing position, calculating a correction value reflecting the quality of the ball and the lie of the swing position and the type of club and applying it to the aiming, and enabling the address to be corrected through the vibration of the left and right shoes so that other companions cannot recognize it, so that it is a system that enables quick and accurate aiming without disturbing the companions' golf.

[0037] In the case of beginner golfers, it is not that they are clumsy in aiming at the target, but rather, even if they have accurate aiming, there are many cases where the result of the swing is not good due to mistakes that occur because the user's address alignment is not straight toward the aiming direction.

[0038] In particular, the alignment of the feet at address varies depending on the golfer's ball quality, but if this is not reflected and the alignment of the feet at address is followed by another golfer, the swing results are often poor even if the golfer has a good ball quality and a good club path.

[0039] In addition, for non-advanced golfers, there are many golfers who have different swing characteristics for their driver swing and iron swing, that is, swings of iron clubs such as woods, utilities, and iron clubs. Therefore, aiming must be corrected by taking this into account, but it is not easy to correct aiming probabilistically using swing history.

[0040] Accordingly, the smart golf shoes (2) included in the automatic aiming system using smart golf shoes according to one embodiment of the present invention are shoes that memorize the targeting direction in which the initial user looks at the target, and enable the user to address the target accurately with a direction angle set perpendicular to the targeting direction or by each user, thereby assisting the user to accurately address the target according to the user's desired aim even in the field.

[0041] To this end, the smart golf shoes (2) included in the automatic aiming system using smart golf shoes according to one embodiment of the present invention include a communication module (4) for communicating with a smart shoe management app (20) built into a user's smartphone (22); a signal input switch (6) for inputting an aiming start signal toward a target; a sensor module (8) for detecting an aiming direction and an address direction angle with respect to the aiming direction according to an input of the signal input switch (6); and a vibrator (14) provided on the inner bottoms of the left and right shoes (2a, 2b) for generating vibrations so as to adjust the address direction angle with respect to the aiming direction and for generating vibrations to notify the user of a standing state according to the set address direction angle.

[0042] At this time, the above communication module (4) is a short-distance communication module including Bluetooth, and in addition to Bluetooth, modules that apply Zigbee or various short-distance communication methods can all be used.

[0043] Meanwhile, the signal input switch (6) is a contact switch that is provided at the front ends of the left and right shoes (2a, 2b), respectively, and generates an input signal by striking the floor with the front toe of the shoe. In the smart golf shoe (2) according to one embodiment of the present invention, for example, when inputting an aiming signal for a target to set a user-specific address direction for a target, and when inputting an aiming signal for rounding in a state where the user-specific address direction angle for the target has already been set, the signal input switch (6) formed at the front end of the right shoe (2b) is operated by making one shoe, for example, the left shoe (2a), face the target, and then lifting the other shoe, that is, the right shoe (2b), and hitting the front end thereof on the tee box.

[0044] In addition, the sensor module (8) is configured to include a geomagnetic sensor (10) for detecting the direction angle, and may further include a gyroscope (12) for detecting the inclination of the shoe.

[0045] In the case of the geomagnetic sensor (10), since the position of true north can always be detected, it can be used to calculate the aiming direction angle in comparison with the true north. The geomagnetic sensor (10) mentioned in the present invention can be applied to various sensors that measure true north and direction angle, such as a digital gyro compass.

[0046] To this end, in the automatic aiming system using smart golf shoes according to one embodiment of the present invention, the smart shoe management app (20) that memorizes address direction angle information for each user with respect to the target direction, communicates with the smart golf shoes (2) of the present invention, determines whether the current address direction angle of the user is correct, and provides guidance on the address direction angle is installed on the user's smartphone (22).

[0047] When the above smart shoe management app (20) processes the setting operation and setting value memory when the user sets his / her address direction angle with respect to the target direction, the user does not need to carry the user smartphone (22) thereafter.

[0048] More specifically, the user smartphone (22) comprises a control unit (32) whose basic function is to calculate the user-specific address direction angle for the aiming direction, detect the current address direction angle of the corresponding user, compare it with a set value, and process it so that the address direction can be adjusted; a memory (30) for storing the user-specific address direction angle for the aiming direction; and a key input unit (26) for inputting a start signal for setting the user-specific address direction angle and a signal for completing the setting of the user-specific address direction angle.

[0049] In the case of the above-mentioned geomagnetic sensor (10), since the position of true north can always be detected, the control unit (32) calculates and memorizes the aimed direction angle in comparison to the true north, and then when the golfer turns in a specific direction, it can detect the degree of rotation.

[0050] Meanwhile, the control unit (32) controls the vibration signal to be generated only in one of the vibrators (14) provided in each of the left and right shoes (2a, 2b), thereby enabling the user to rotate in the direction in which the vibration is generated, thereby enabling an accurate address to the target.

[0051] For example, assuming that the directional angle setting value of the user's address to the target is (90 degrees - θ3) for the left shoe (2a) and (90 degrees + θ4) for the right shoe (2b), if the user's address directional angle is less turned to the right than the target, the control unit (32) generates vibration in the user's right shoe (2b), and if the user has turned too much to the right, the control unit (32) generates vibration in the user's left shoe (2a).

[0052] At this time, in the case of the left shoe (2a) and the right shoe (2b), if the left shoe (2a) is correctly addressed, the right shoe (2b) is preferably used for the judgment of the correct address direction angle for the target, since the stride length and angle at which the golfer habitually stands are specific to each golfer.

[0053] However, it is to be understood that the present invention does not mean that the directional angle reference, as described above, limits the right only to the left shoe (2a).

[0054] In addition, if the user is positioned to have a preset address direction angle with respect to the target direction, the control unit (32) causes vibrations to occur simultaneously in the left shoe (2a) and the right shoe (2b), thereby allowing the user to recognize that he or she has an accurate aiming address.

[0055] As explained above, when a virtual line is drawn from the target, i.e. pin (5), to the user's address point, the user's address may be a standard user as in Fig. 4a, a user may address with an open stance as in Fig. 4b, or a user may address with a closed stance as in Fig. 4c, depending on the ball quality.

[0056] Accordingly, the smart shoe management app (20) provided in the automatic aiming system using smart golf shoes according to one embodiment of the present invention sets and memorizes the direction angle for each user for each specific stance for each address of each user, preferably the direction angle for the left shoe (2a).

[0057] In addition, since the smart golf shoes (2) according to one embodiment of the present invention process aiming control for a target through vibration, other companions other than the golfer wearing the smart golf shoes (2) cannot know whether the golfer is wearing the smart golf shoes (2).

[0058] Meanwhile, the smart shoe management app (20) provided in the automatic aiming system using smart golf shoes according to one embodiment of the present invention has a golf course map driving unit (34) therein, and the golf course map driving unit (34) transmits information on the effective direction angle excluding the penalty zone and the out-of-bounds (OB) zone from the swing position where the golfer is currently located to the control unit (32) so as to reflect it during correction.

[0059] In addition, the golf course map driving unit (34) considers a specific point at the request of the control unit (32), for example, a point at which a golfer generates a signal requesting aiming through the smart shoes (2), as an actual landing point (RL) and displays it, and displays the next target landing point (TL) or hole cup (Hole) and displays an aiming virtual line (A) or an actual hitting line (B) connecting each point on the screen as illustrated in FIG. 6.

[0060] To this end, the control unit (32) controls to display the point where the second shot or more and the signal requesting aiming are generated as the actual landing point (RL), and controls to display an aiming virtual line (A) connecting the actual landing point (RL) to the next target landing point (TL) or hole cup (Hole).

[0061] Meanwhile, the smart shoe management app (20) is provided with a correction value calculation unit (36) therein, and the correction value calculation unit (36) determines whether the club to be swung is a driver or an iron club based on the previous swing position, that is, determines whether it is a tee shot or a field shot based on the swing position, and calculates the correction value by applying the variables by figuring out the actual golfer's ball quality based on the swing result value based on the previous swing position and landing position, and calculates the correction value by using the aiming virtual line as the target hitting line, thereby applying the correction directional angle signal to the control unit (32) so that it can be applied to the smart shoes (2).

[0062] To this end, the memory (30) provided in the smart shoe management app (20) stores the golfer's previous swing information and the swing result information from the golfer's previous round.

[0063] That is, it is preferable that the basic correction operation performed in the smart shoe management app (20) is performed in the control unit (32), and additional correction value operation utilizing additional variables is additionally performed in the correction value operation unit (36), and the operation value is output through the control unit (32).

[0064] At this time, the previous swing result information is information about whether the club swung was a driver or an iron club, lie information of the swing point (e.g., hook lie where the ball is higher than both feet, slice lie where the ball is lower than both feet, high slant lie with the left foot, low slant lie with the left foot, etc.), and result information about the distance and direction of the actual swing reflecting such club and lie information. The memory (30) stores the previous swing information and allows the previous swing information to be reflected when the golfer wants to swing at a specific point.

[0065] At this time, in the case of a tee shot at the tee box of hole 1 or a second shot at hole 1 where swing information immediately before the current swing is not stored in the memory (30), the swing result information of the tee shot or second shot in the previous round is used to calculate the correction value.

[0066] Accordingly, in an automatic aiming system using smart golf shoes according to an embodiment of the present invention, when a golfer inputs an aiming request signal to the smart shoe management app (20) using the smart shoes (2), the smart shoe management app (20) activates a sensor, receives location information of a point where a corresponding swing is prepared from the golf course map driving unit (34), determines whether the point where a swing is prepared is a tee box or a field, and calculates a correction direction angle by reflecting the result value of a previous swing for the driver or iron of the corresponding golfer.

[0067] At the same time, the smart shoe management app (20) displays an aiming virtual line (A) connecting the target landing point (TL) and the point of preparing for the swing on the golf course map from the golf course map driving unit (34), and selectively applies a vibration signal to the left and right smart shoes (2a, 2b), thereby enabling the golfer to quickly take an address suitable for accurate aiming.

[0068] The functions and operations of an automatic aiming system using a smart golf shoe according to an embodiment of the present invention having the above-described configuration are described in detail with reference to the attached drawings.

[0069] FIG. 8 is a signal flow diagram illustrating a state of setting individual address information through an automatic aiming system using smart golf shoes according to one embodiment of the present invention.

[0070] First, an automatic aiming system using smart golf shoes according to an embodiment of the present invention can set, for example, a user-specific address direction for a target, that is, a user-specific address direction reflecting a specific stance according to the quality of each golfer's ball, by, for example, a user operating the user smartphone (22) to drive the smart shoe management app (20).

[0071] In that state, the user selects a user-defined key on the smart shoe management app (20). Then, the user-defined key selection signal is input to the control unit (32), and the control unit (32) generates a control signal to the sensor module (8) mounted on the shoe (2) in that state to request a sensor value.

[0072] In that state, when the user clicks the target designation button on the smart shoe management app (20), the control unit (32) generates a control signal to the sensor module (8) to request the aiming direction sensor value.

[0073] Then, the sensor module (8) detects the detection value for the aiming direction angle compared to the true north value of the geomagnetic sensor (10) and transmits it to the control unit (32).

[0074] In that state, the user operates the signal input switch (6) of the shoe, such that one shoe, for example, the left shoe (2a), faces the target, and then lifts the other shoe, that is, the right shoe (2b), and taps its front end on the tee box, thereby activating the signal input switch (6) formed at the front end of the right shoe (2b).

[0075] Then, the sensor module (8) is activated, and the user rotates the body to address the target.

[0076] Then, the sensor module (8) detects the address direction angle information rotated relative to the target direction and transmits it to the control unit (32) and outputs it on the screen through the display unit (28).

[0077] In that state, when the user selects the address setting key, the control unit (32) preferably registers the address direction angle and the user's two-foot stand information as well.

[0078] The two-foot stance for each user is explained in detail below.

[0079] First, in the present invention, the user can address in various stances as shown in FIGS. 4a, 4b, and 4c, and the stance information is stored together with the direction angle information for each user, and this is guided during addressing to enable the user to aim accurately.

[0080] For example, assuming that the directional angle setting value addressed by the user to the target is (90 degrees - θ3) for the left shoe (2a) and (90 degrees + θ4) for the right shoe (2b), a constant directional angle of (90 degrees - θ3) for the left shoe (2a) is preferably stored in the memory (30) to reflect the stance of each user.

[0081] If the user has a standard stance, the address will be made in a direction perpendicular to the target direction, and if the user has a closed stance, the address will be made in a direction angle that is set in advance, so that the left shoe (2a) will first guide the direction angle.

[0082] FIG. 9 is a signal flow diagram illustrating an aiming processing state through an automatic aiming system using smart golf shoes according to one embodiment of the present invention.

[0083] First, the user lifts the right shoe (2b) while looking at the target, i.e., the pin (5), preferably while looking at the left shoe (2a) toward the pin (5) or, if it is a tee box, toward the IP pin, and causes the front end to collide with the ground.

[0084] Then, a signal is input to the signal input switch (6), and preferably, when the signal input switch (6) is operated twice, it is preset as a valid signal.

[0085] That is, when the signal input switch (6) is operated twice, the sensor module (8) is activated, and in that state, the user addresses the target by rotating the body approximately 90 degrees in the direction of the target.

[0086] Then, the sensor module (8) detects the direction angle for the target and transmits the direction angle information to the control unit (32) of the user smartphone (22), and the control unit (32) calculates the rotation angle.

[0087] And, the control unit (32) calls the user's address setting value that has been saved in advance, compares the angles, and if the appropriate rotation is less than that, it determines that the address is in the wrong direction and guides direction adjustment.

[0088] More specifically, the control unit (32) controls the vibration signal to be generated only in one of the vibrators (14) provided in each of the left and right shoes (2a, 2b), thereby enabling the user to rotate in the direction in which the vibration is generated, thereby enabling an accurate address to the target.

[0089] For example, assuming that the directional angle setting value of the user's address to the target is (90 degrees - θ3) for the left shoe (2a) and (90 degrees + θ4) for the right shoe (2b), if the user's address directional angle is less turned to the right than the target, the control unit (32) generates vibration in the user's right shoe (2b), and if the user has turned too much to the right, the control unit (32) generates vibration in the user's left shoe (2a).

[0090] At this time, in the case of the left shoe (2a) and the right shoe (2b), if the left shoe (2a) is correctly addressed, the right shoe (2b) is preferably used for the judgment of the correct address direction angle for the target, since the stride length and angle at which the golfer habitually stands are specific to each golfer.

[0091] In addition, if the user is positioned to have a preset address direction angle with respect to the target direction, the control unit (32) causes vibrations to occur simultaneously in the left shoe (2a) and the right shoe (2b), thereby allowing the user to recognize that he or she has an accurate aiming address.

[0092] FIG. 10 is a signal flow diagram illustrating an aiming processing state in which a correction value is reflected through an automatic aiming system using smart golf shoes according to an embodiment of the present invention.

[0093] First, in an automatic aiming system using smart golf shoes according to an embodiment of the present invention, when a golfer inputs an aiming request signal to the smart shoe management app (20) using the smart shoes (2), the smart shoe management app (20) activates a sensor, receives location information of a point where a corresponding swing is prepared from the golf course map driving unit (34), and compares the location information of that point with the golf course map to determine whether the point where a swing is prepared is a tee box or a field.

[0094] More preferably, since the golfer's swing quality may be different depending on whether the point where the golfer prepares for the swing is a tee box or a field, that is, depending on whether the club is a driver or an iron (e.g., wood, utility, long iron, middle iron, wedge, chipper, etc.), the smart shoe management app (20) can calculate a correction value by considering the swing quality and distance of each club based on the golfer's previous swing result information, thereby varying the target landing point.

[0095] At this time, in the case of a tee shot at the tee box of hole 1 or a second shot at hole 1 where the swing result information immediately before the current swing is not stored in the memory (30), the smart shoe management app (20) can utilize the swing result information of the tee shot or second shot in the previous round to calculate the correction value.

[0096] When the target direction angle calculation is completed through the correction value calculation in the above smart shoe management app (20), the user can address the target direction by rotating the torso approximately 90 degrees.

[0097] Then, the sensor module (8) detects the direction angle for the target and transmits the direction angle information to the control unit (32) of the user smartphone (22), and the control unit (32) calculates the rotation angle.

[0098] And, the control unit (32) calls the user's address setting value that has been saved in advance, compares the angles, and if the appropriate rotation is less than that, it determines that the address is in the wrong direction and guides direction adjustment.

[0099] More specifically, the control unit (32) controls the vibration signal to be generated only in one of the vibrators (14) provided in each of the left and right shoes (2a, 2b), thereby enabling the user to rotate in the direction in which the vibration is generated, thereby enabling an accurate address to the target.

[0100] When the user is positioned to have a preset address direction angle with respect to the target direction, the control unit (32) causes vibrations to occur simultaneously in the left shoe (2a) and the right shoe (2b), thereby allowing the user to recognize that he or she has an accurate aiming address.

[0101] Meanwhile, the automatic aiming system using smart golf shoes according to an embodiment of the present invention is not limited to the above-described embodiment, but various changes are possible within a scope that does not deviate from the technical gist thereof.
