Golf is a game in which a ball is put into a green hole located at a certain distance, and the player who puts the ball into the hole with the shortest number of strokes is the winner.

What is important in these golfs is the distance and accuracy of the shots. Since distance and shots are accurate, you can reduce the number of bats, so all players practice a lot for distance and accurate shots. However, even if the swing and the moment of impact are correctly understood to improve the distance and accuracy of the shot, if the golf swing axis such as head-up does not change the habit of shaking before impact , Accurate shot with long distance is impossible. Head-up refers to the action of raising the head before impact in golf.

Beginner players unconsciously head up or swing axes will collapse, so it is necessary to practice constantly to correct the swing axis. However, there is a limit to correcting the swing posture when the user can not recognize the change of the swing axis himself.

The processor 140 starts sensing the golf swing axis change based on the user's starting motion. A detailed description of the operation of the processor 140 will be given later.

The memory 150 stores predetermined start condition information and a critical range for each mode of the assistant device 100 for golf training. As described above, the golf training auxiliary device 100 operates in the setting mode and the sensing mode. The start condition means a reference condition for determining whether or not the golf training auxiliary device 100 starts to detect the swing axis change, and can be determined by the user in the setting mode.

4 is a flowchart of a golf swing axis change detection method of an auxiliary golf training apparatus according to an embodiment of the present invention. FIGS. 5A and 5B are views for explaining the principle that the golf training auxiliary device according to an embodiment of the present invention starts sensing golf swing axis change. FIG. FIG. 6 is a view for explaining a principle of sensing a golf swing axis change according to an auxiliary golf training apparatus according to an embodiment of the present invention. Hereinafter, a golf swing axis change detection method of an auxiliary golf training apparatus according to an embodiment of the present invention will be described in detail with reference to FIG. 4 to FIG.

Referring to FIG. 4, the golf swing axis change detection method of the golf training auxiliary device according to an embodiment of the present invention detects start rotation (S410).

The golf swing is divided into seven stages: address, take back, top, down swing, impact, follow through and finish. . In step 7, the address refers to the position where the club is held on the ground by holding the foot posture before hitting the golf ball, which corresponds to the beginning of the golf swing. The golf practice aid detects the start rotation to ensure that the user takes the address action. The start rotation means a movement indicating that the address operation of the user has started. The start rotation may be caused by the user moving the head wearing a hat with a golf training aid. For example, the user can inform the start of the golf swing by swinging his head up and down. In this case, the golf training auxiliary device attached to the golf cap may rotate as the user's head shakes, and the gyroscope sensor senses the rotational motion caused by the shaking of the user's head. That is, when the user shakes the head up and down, it is detected as the start rotation.

The golf swing shaft change detection method of the golf training auxiliary apparatus according to an embodiment of the present invention determines whether the start rotation corresponds to a predetermined start condition at step S420. If the start rotation satisfies the start condition, A change of the golf swing axis of the user is sensed (S430).

The start condition can be preset by the user and stored. That is, the user can set a start condition by wearing a golf cap with a golf training auxiliary device in advance before starting the golf swing and moving the head in a desired direction in the setting mode. For example, the user can set the start condition to nod the head up and down before taking the address posture. In this case, the gyroscope sensor detects the rotational motion, and the rotational direction, rotational angle, number of rotations, and the like of the rotational motion can be set as a start condition because the golf training auxiliary device is rotated along the nod head axis.

Referring to FIG. 5A, the start condition SA1 may be set to the rotational direction and the rotational angle of the rotational motion. For example, as described above, in the setting mode, the user can set an operation to nod his head up and down as a start condition (SA1), and the processor detects the rotational direction of the rotational motion sensed by the gyroscope sensor, Can be stored in the memory as a start condition (SA1). For convenience of explanation, the rotation angle set to the start condition (SA1) is defined as the start angle, and the rotation direction set to the start condition (SA1) is defined as the start direction. 5A, the range of the starting angle is indicated by a dotted line, and the starting direction is indicated by a thin arrow.

Before entering the address operation, the user can generate a start rotation SM1 by nudging the head up and down. 5A, the start rotation SM1 is shown by a bold arrow. In this case, the gyroscope sensor senses the start rotation SM1, and the golf swing axis change detection unit calculates the rotation direction and the rotation angle of the start rotation SM1, respectively, and compares the start direction and the start angle. If the rotation direction of the start rotation SM1 coincides with the start direction of the predetermined start condition SA1 and the rotation angle of the start rotation SM1 exceeds the start angle of the predetermined start condition SA1, The rotation SM1 may correspond to the start condition SA1. In this case, the golf training auxiliary device recognizes that the user has entered the address operation, and then detects the change of the golf swing axis of the user.

In addition, the start condition SA1 may be set as a rotation direction, a rotation angle, and a rotation number. For example, the user can set the start condition (SA1) to nod twice the head up and down in the setup mode, and the processor sets the rotation direction, rotation angle and rotation number of the rotation motion caused by nodding the head It can be stored in the memory as a start condition (SA1). For convenience of explanation, the rotation direction, rotation angle, and rotation number stored in the start condition (SA1) are defined as a start direction, a start angle, and a start count, respectively. Thereafter, the user may be aware of the golf practice aid device to begin swinging by nudging the head up and down twice before taking the address action. In this case, the processor measures the rotation direction and the rotation angle of the start rotation SM1 caused by the user's head nod and counts the rotation number. Thereafter, the processor compares the rotation direction and the rotation angle of the start rotation SM1 with the start direction and the start angle, respectively, and compares the rotation number of the start rotation SM1 with the start number. If the start rotation SM1 matches the start condition SA1, the golf training aid detects a change in the golf swing axis of the user.

On the other hand, referring to FIG. 5B, the start condition SA2 may be set to a time at which the rotation angle and the rotation angle of the specific range are maintained. The user's head can be tilted at a certain angle while the user takes the address action, and the tilted head can be held for a certain period of time. The processor recognizes the degree to which the user's head is tilted and the time the head is tilted as the start rotation (SM2). That is, the processor recognizes that when the user's head angle is included in the range of the start angle of the start condition SA2 and the rotation angle of the start rotation SM2 is maintained for a predetermined time, the user starts to swing, Golf swing axis change detection can be started.

Referring to FIG. 4 again, the golf swing axis change detecting method of the golf training auxiliary apparatus according to an embodiment of the present invention determines whether the rotation angle of the rotational motion generated according to the golf swing axis change of the user exceeds a predetermined threshold range (S440), and generates a warning when the rotational angle of the rotational motion exceeds the threshold range (S450).

Referring to FIG. 6, in the golf swing operation, the user's golf swing axis needs to be fixed constantly for a proper time before and after impact. If a golf swing axis change such as head-up occurs in the swing motion, the user's head moves and the rotational angle MA measured through the gyroscope sensor changes. The processor determines that a golf swing axis change has occurred and generates an alert if the rotation angle MA exceeds a predetermined threshold range TA. The user is alerted by the alarm whether the golf swing axis has changed.

As described above, the critical range TA can be changed according to the mode of the golf practice auxiliary device. For example, the mode of the golf training aid may be classified into an entry mode, an intermediate mode, and an advanced mode, and the threshold range TA may be broader from the advanced mode to the entry mode. In this case, the user can easily practice the swing posture according to his or her skill, and intuitively and quickly recognize whether the golf swing axis has changed, so that the golf swing posture correction can be made easier.

The warning generated by the golf swing axis change is generated from the output unit. As described above, the output unit outputs at least one of an audible warning, a visual warning, a sense of smell, and a tactile warning. For example, the processor senses whether the golf swing axis has changed and generates a warning control signal, and the output unit generates a warning sound based on the warning control signal. In some embodiments, an earphone may be separately connected to the golf training aid. In this case, the user can recognize the golf swing shaft via the earphone, and the ambient noise due to the warning sound can be reduced.

The golf training auxiliary device according to an embodiment of the present invention automatically detects a golf swing axis change occurring in a golf swing operation and allows the user to recognize whether the golf swing axis has changed or not. That is, the golf training auxiliary device includes a gyroscope sensor for sensing the rotational motion, and is attached to the golf cap to automatically detect whether the golf swing axis changes or not, thereby generating various alerts.

In particular, the golf training aid apparatus according to an embodiment of the present invention starts sensing the golf swing axis change after the start rotation corresponding to the start condition is detected. If the golf training auxiliary device detects a change in the golf swing axis with respect to all movements, even if the golf swing is not performed, the change in the golf swing axis is detected, so that the movement other than the golf swing can be misinterpreted as the change in the golf swing axis. Turns off the power of the golf training aid if the golfer does not swing the golf swing, and turns on the power of the golf training aid when the golf swing is started. The golf training auxiliary device according to an embodiment of the present invention determines whether or not the start rotation corresponds to a predetermined start condition in order to solve the troubles and the mistake recognition problem, And starts sensing the golf swing axis change from that point of time. Since the start condition can be set in advance by the user himself / herself, the user can easily operate the golf training auxiliary device with only a specific movement without operating any key in the address posture.

In addition, since the golf training auxiliary device according to the embodiment of the present invention can be implemented with a relatively simple structure, the manufacturing cost can be saved, and the golf training auxiliary device can be implemented with a small size, which is advantageous in that it is easy to carry.

Although the embodiments of the present invention have been described in detail with reference to the accompanying drawings, it is to be understood that the present invention is not limited to those embodiments and various changes and modifications may be made without departing from the scope of the present invention. . Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
