Referring to FIG. 3, a method of controlling the electronic device 100 related to one embodiment will be described. 3 is a flowchart of a method for controlling an electronic device according to an embodiment.

First, the location acquisition sensor 121 acquires the current location (S310).

The location acquisition sensor 121 may acquire the coordinates of the current location of the electronic device 100. According to an embodiment of the present invention, since the user mainly wears the electronic device 100 on the wrist, the current location of the electronic device 100 may be the same as the user's current location. The current location of the electronic device 100 may be obtained periodically and may be updated according to user input.

The control unit 170 determines the shot mode (S320).

Specifically, the control unit 170 can determine the shot mode using the coordinates of the current location and course map information corresponding thereto. For example, the control unit 170 may read course map information corresponding to the coordinates of the current location from the memory 160. The control unit 170 combines the read course map information and the current location information obtained from the location acquisition sensor 121 to determine whether the current electronic device 100 is near the tee box, on the fairway, outside the green, or inside the green. You can determine whether it is recognized or not.

Based on this, the control unit 170 may determine the full swing mode when the current location of the electronic device 100 is on a tee box or on the fairway. Additionally, the control unit 170 may determine the approach mode when the current location of the electronic device 100 is within a preset range from the green. For example, if the current location of the electronic device 100 is within 50 m from the green, it may be determined to be in approach mode. If the current location of the electronic device 100 is on the green, the control unit 170 may determine that it is in putting mode.

Of course, the user may select a shot mode different from the shot mode determined by the control unit 170 through the user input unit 130. Then, the control unit 170 can perform the next step based on the shot mode selected by the user.

The control unit 170 obtains the user's motion data (S330).

The control unit 170 may obtain the user's motion data from the inertial sensor 122. Here, the user's motion data may be a motion input including the user's wrist raising motion and/or wrist rotating motion. For example, as the user lifts the electronic device 100 from a dropped pose to an elevated pose, the user performs a wrist raise and/or wrist rotation motion. Then, the control unit 170 determines wrist raising and/or wrist rotation actions based on this motion input.

Then, the control unit 170 determines whether the user's motion corresponds to a valid swing (S340).

Typically, during a golf game, most players take several practice swings without hitting the golf ball all at once. Accordingly, in order to calculate an accurate golf score, it is necessary to distinguish between practice swings and effective swings that actually hit a golf ball. To this end, the control unit 170 analyzes acceleration and angular velocity information among the motion data received from the inertial sensor 122, determines whether the effective swing condition is satisfied, and distinguishes between a practice swing and an effective swing. The control unit 170 can determine whether impact has been applied to the golf ball using the maximum magnitude value of the acceleration information.

One golf swing is largely comprised of address (positioning the feet and placing the club on the ground before hitting the ball), backswing (pulling the golf club back after address as a preparation for applying force), and downswing (hitting the golf ball after the backswing). It consists of a downward swing motion to hit the golf ball) and a follow swing (a motion to push the ball forward after hitting it).

That is, in one swing, the head of the golf club reaches the top of the backswing through the backswing after the address point, and reaches the point of impact through the downswing from the top of the backswing. In other words, the time taken from the address point to the top point of the backswing is the backswing period, and the time taken from the top point of the backswing to the point of impact is the downswing period. The combination of the backswing period and the downswing period can be called shot tempo.

Specifically, first, the control unit 170 may calculate the swing singularity from motion data. Here, the swing singularity is the address point, backswing top point, and impact point.

When addressing, the user takes the action of stopping the golf club near the golf ball for a certain period of time. That is, when addressing, the speed/angle of the golf club is maintained or the amount of change is maintained below a certain threshold. Accordingly, the control unit 170 may determine the point at which the speed before the backswing is minimum is the address point. In other words, the point where the club head speed is minimum before the backswing period begins can be the address point.

Additionally, the control unit 170 may determine the point where the speed is minimum after the backswing occurs as the top point of the backswing. In other words, the point where the backswing period ends and the downswing period begins can be the backswing top point.

The method of determining the impact point may vary depending on the type of shot mode.

In the case of full swing mode and approach mode, the control unit 170 may determine the point where the angular velocity (gy) of the gyro sensor has the minimum value as the impact point.

In the case of putting mode, the control unit 170 may determine the point where the slope of the acceleration (az) of the acceleration sensor is maximum as the impact point. That is, the control unit 170 may determine that the point at which the change in acceleration of the acceleration sensor is the maximum at an arbitrary time (t) and the time just before (t-1) is the impact point.

Meanwhile, the amount of impact generated when swinging may be equal to the size (an) of the acceleration sensor. For example, the impulse will have a maximum value when the head of a golf club strikes the ball at the point of impact.

Since the form of the swing performed depending on the shot mode is different, the effective swing satisfaction condition may be different depending on the mode. The control unit 170 may determine whether the effective swing condition is satisfied based on the period between swing singularities.

In the full swing mode, the control unit 170: i) the backswing period is greater than or equal to the preset first reference time (T1), ii) the downswing period is greater than or equal to the preset second reference time (T2), and iii) If the maximum value of the impulse is greater than or equal to the first threshold, it is determined that the effective swing condition is satisfied.

In the case of the approach mode, the control unit 170 controls i) the backswing period to be greater than or equal to the preset third reference time (T3), ii) the downswing period to be greater than or equal to the preset fourth reference time (T4), and iii) the amount of impulse. If the maximum value is greater than or equal to the second threshold, it is determined that the valid swing condition is satisfied.

In the case of putting mode, the control unit 170 controls i) the backswing period to be greater than or equal to the preset fifth reference time (T5), ii) the downswing period to be less than the preset sixth reference time (T6), and iii) the gyro sensor. If the maximum value of the angular velocity (gy) is less than the third threshold, it is determined that the effective swing condition is satisfied.

Generally, in full swing mode on the tee box or fairway, the backswing period is long and the impact size is large. In addition, in the putting mode performed on the green, the backswing period is short and the impact size is small for putting the golf ball into the hole cup.

Based on this, comparing the sizes of preset reference times, the first reference time (T1) > the third reference time (T3) > the fifth reference time (T5), and the second reference time (T2) > the fourth. The reference time (T4) may be > the sixth reference time (T6). Additionally, the first threshold value > the second threshold value > the third threshold value.

However, if a valid swing is made multiple times within a predetermined time in the full swing mode and the approach mode, the control unit 170 may determine that the swing previously determined to be a valid swing is not a valid swing. For example, if the control unit 170 determines that the acquired motion data is a valid swing, it counts the number of shots, but if another motion data is acquired within a predetermined time, the number of shots counted for the first hit is canceled. can do.

Even if it is a valid swing, the control unit 170 may determine that it is not a valid swing according to the user's input through the user input unit 130. Accordingly, the control unit 170 can cancel the counted number of shots. In addition, even if it is not a valid swing, the control unit 170 may determine that it is a valid swing according to the user's input through the user input unit 130 and count the number of shots.

If the control unit 170 determines that the swing corresponds to a valid swing, a screen corresponding to the valid swing may be displayed on the display unit 151 (S350). If the control unit 170 determines that the user's motion does not correspond to a valid swing, step S310 may be performed again.

In addition to the course map image, the control unit 170 displays a screen preset by the user, for example, a user interface including the current time, a user interface indicating the remaining distance from the current location to the hole and the altitude difference between the current location and the hole. etc. may be displayed, but is not limited thereto. This image can always be displayed on the display unit 151 after starting the golf game.

When a valid swing is made in full swing mode/approach mode, the control unit 170 may increase the accumulated number of strokes of a shot and display the accumulated number of strokes on the display unit 151. Additionally, when a valid swing is made in the putting mode, the control unit 170 may increase the number of strokes made and display the accumulated number of putts on the display unit 151.

This will be described with reference to FIG. 4 . Figures 4 and 5 are diagrams showing a screen displayed on a display unit of an electronic device.

Referring to FIG. 4, the display unit 151 may display a shot tempo screen 4001. The shot tempo screen 4001 may include a shot tempo 4003, a backswing period 4005, and a downswing period 4007. The backswing period is 2.0, shown in grey, and the downswing period is 0.6, shown in black. The backswing period 4005 and the downswing period 4007 may be displayed in different colors to facilitate distinction.

The user can adjust the speed of the swing by checking the shot tempo of the user's swing. The shot tempo screen 4001 may be displayed on the display unit 151 when motion data is acquired even if it is not determined to be a valid swing.

Additionally, the shot tempo screen 4001 may include a number of strokes information display unit including a shot information display unit 4009 and a putt information display unit 4013, a shot number indicator 4011, and a putt number indicator 4015. This will be described in more detail with reference to FIG. 5.

The green strategy screen (4002) is a screen that shows the overall shape and length of the green (4017), the remaining distance to the safe area after the green (4018), undulation, and the location of the pin (4019), allowing the user to view the green and its surroundings. Make sure you know in advance. Undulation can be expressed in colors, contours, etc.

As shown in FIG. 5, the green strategy screen 4002 may include a number of strokes information display unit. The number of strokes information display unit, that is, the shot information display unit 4009 and the putt information display unit 4013, may be located along the periphery of the display unit 151. For example, the shot information display unit 4009 may be located at the edge of the display unit 151.

The number of shots indicator 4011 is located below the shot information display unit 4009 and can indicate the number of shots. Additionally, the number of strokes of putt indicator 4015 may be located below the putt information display unit 4013 to indicate the number of strokes of putt. The shot count indicator 4011 and the putt count indicator 4015 may be displayed in different colors to facilitate distinction.

As shown in FIGS. 4 and 5, the shot information display unit 4009 has a section in which the number of shot strokes indicator 4011 can be positioned from 0 to 6, and the put information display portion 4013 has the number of putts indicator 4011 from 0 to 4. There may be a space where the indicator 4015 can be located. However, the present invention is not limited to this, and the shot information display unit 4009 and the putt information display unit 4013 may have different numbers of columns.

For example, a box in which the number of shots indicator 4011 can be located can be positioned so that the number of accumulated shots increases clockwise. As shown in Figures 4 and 5, the shot information display unit 4009 starts at the 12 o'clock position and shows the accumulated number of shots increasing clockwise until it reaches the 6 o'clock position. The put information display unit 4013 may be positioned to increase clockwise from the position next to the position where the shot information display unit 4009 ends. Similarly, the space where the number of putts indicator 4015 can be located can be positioned so that the number of accumulated number of putts increases clockwise. As shown in Figures 4 and 5, the putt information display unit 4013 starts at the 7 o'clock position and shows the accumulated number of shots increasing clockwise until the 11 o'clock position. The positions of the shot information display unit 4009 and the putt information display unit 4013 and the arrangement of the cells in which each indicator can be located are not limited to this and may have various positions and arrangements.

The green strategy screen 4002 shown in FIG. 5 shows a case where one shot is performed. For example, if the number of strokes of a shot is 0, the shot number indicator 4011 may be located at the bottom of the SHOT column of the shot information display unit 4009, and if the number of strokes of a putt is 0, the number of strokes indicator 4011 may be located in the PUTT column of the put information display unit 4013. A putt number indicator 4015 may be located at the bottom of .

Afterwards, if the control unit 170 determines that the user's movement in the full swing mode/approach mode corresponds to a valid swing, the cumulative number of shots is increased, and the number of shots indicator 4011 in the display unit 151 shows 1. It can be displayed to be located at the bottom of the shot information display unit 4009.

If the number of shots made exceeds the number of cells shown in the shot information display unit 4009 on the display unit 151, the number of shots made can be displayed using a plurality of shot number indicators 4011. For example, if the number of strokes of a shot is 7, the control unit 170 displays two shot number indicators 4011 located below each shot information display unit 4009 indicating 1 and 6 to indicate the number of strokes of a shot. You can. This is the same in the case of the putt information display unit 4013, when the number of strokes of a putt exceeds the number of cells shown in the putt information display unit 4009 on the display unit 151, a plurality of strokes of putt indicators 4015 are used to indicate the number of strokes of a putt. The number of strokes can be displayed.

The green strategy screen 4002 may be output on the display unit 151 for a certain period of time. The time at which the green strategy screen 4002 is displayed may vary depending on the shot mode. This is because the time it takes for the ball to reach its destination may vary depending on the shot mode. For example, in the case of full swing mode, a green strategy screen 4002 may be displayed on the display unit 151 for 30 seconds. In the case of approach mode, a green strategy screen 4002 may be displayed on the display unit 151 for 10 seconds. Lastly, in the case of putting mode, a green strategy screen 4002 may be displayed on the display unit 151 for 5 seconds.

Since the number of shots and number of putts must be initialized and counted again from 0 every time a new hole starts, the number of shots and putts indicator 4011 is located at the bottom of the SHOT section of the shot information display unit 4009, and the number of strokes of putt indicator 4015 Can be located at the bottom of the PUTT section of the put information display unit 4013.

In addition, the control unit 170 can display the shot tempo screen 4001 and the green strategy screen 4002, as well as various screens, as well as the shot information display unit 4009 and the putt information display unit 4013 on the display unit 151. . Of course, the control unit 170 displays information on the number of shots and putts, a shot information display unit 4009, a putt information display unit 4013, a shot number indicator 4011, and a putt number indicator 4015. It is also possible to display on the display unit 151. In other words, the user can know the number of shots and putts at any time.

After the screen corresponding to the effective swing is displayed, the current location of the electronic device 100 may be periodically acquired, and the control unit 170 may perform the operation again from step S310.

According to at least one of the embodiments of the present disclosure, the number of shots and putts performed can be easily confirmed, information related to the score can be confirmed through a simple operation, and the user can conveniently check information appropriate to the user's situation.
