The main body 101 includes a case which forms an appearance. As shown, the case may include a first case 101a and a second case 101b that provide an internal space for accommodating various electronic components.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

3 to 6, a control method of the electronic device 100 according to an embodiment will be described.

Fig. 3 is a flow chart of a control method of an electronic device 100 according to an embodiment, Fig. 4 is a view showing two directions for measuring a distance and an angle in a golf course, Fig. 5 and Fig. And calculates distances and angles corresponding to the two directions in Fig. 4 according to the control method.

Referring to FIG. 3, the position acquisition sensor 121 acquires the current position (S100). The position acquisition sensor 121 may obtain the coordinates of the current position of the electronic device 100. [

The control unit 170 reads the course map information corresponding to the coordinates of the current position from the memory 160 (S102). The course map information may include map image information of a course, accumulation information of a map image, position coordinate information corresponding to reference points of the map image, and the like.

The control unit 170 uses the position coordinate information corresponding to the reference points of the map image of the coarse map information (e.g., including, but not limited to, four corners of the rectangular shaped map image) Can be determined.

The azimuth sensor 123 measures the azimuth of the direction in which the electronic device 100 is oriented (S104). For example, the direction that the electronic device 100 faces may be the direction that a particular portion of the electronic device 100 faces. Alternatively, the user may designate one direction on the interface (map image, compass image, etc.) displayed on the display portion 151a as the direction that the electronic device 100 faces.

The control unit 170 detects whether there is a boundary of the golf course in the direction (azimuth direction) toward which the electronic device 100 is directed (S106). The boundaries of the golf course include boundaries of obstacles (e.g., hazards, OB) located within the golf course. The boundary of the obstacle is included in the form of coordinate information in the course map information.

The control unit 170 detects whether the hazard and the OB are located in the direction of the azimuth angle at the current position using the course map information. As shown in Fig. 4, the user can designate A1 direction or A2 direction from the current position 300 in the fairway FA in the azimuth direction. From the current position 300 of the user, the boundaries FB2 and FB1 of the course are located in the direction A1. The course boundaries FB2 and FB1 are located in the A2 direction from the current position 300 of the user.

Then, the controller 170 calculates the distance from the current position to the boundaries (S108). The control unit 170 may display the calculated distance values on the display unit 151. [

4 and 5, along the direction A1, a total of three boundaries from the current position 300, i.e., a boundary FB2a at which the hazard HA starts, a boundary FB2b at which the hazard HA ends, (FB1a) at which the start point (OA) starts.

The controller 170 calculates the distance from the current position 300 to the boundary FB2a, the distance from the current position 300 to the boundary FB2b, and the distance from the current position 300 to the boundary FB1a .

4 and 6, along the A2 direction, a total of three boundaries from the current position 300, that is, a boundary FB2c at which the hazard HA starts, a boundary FB2d at which the hazard HA ends, (FBe) where the HA restarts.

Then the controller 170 calculates the distance from the current position 300 to the boundary FB2c, the distance from the current position 300 to the boundary FB2d, and the distance from the current position 300 to the boundary FBe .

The tilt sensor 122 measures 110 the angle of the tilt of the electronic device 100 (hereinafter referred to as tilt angle). The tilt sensor 122 can measure the tilted angle of the electronic device 100 with respect to a reference plane parallel to the ground.

5 and 6, if there is an obstacle 200 blocking the field of view or an obstacle 200 obstructing the movement of the golf ball in the hazard HA, the user can move the arm wearing the electronic device 100 And may indicate the end TA of the obstacle 200. The tilt sensor 122 can measure the tilt angles a11 and a21 according to the tilted angle of the arm. In addition, the user can tilt the electronic device 100 in various ways.

At this time, the tilt sensor 122 can correct the measured tilt angle. The tilt angle is measured at a height higher than the golf ball 10. The tilt angle is smaller than the angle with respect to the reference plane of the straight line connecting the golf ball 10 to the end TA of the obstacle 200. [ Therefore, the tilt sensor 122 may add the weight to the measured angle and output it to the control unit 170. [ For example, the tilt sensor 122 may calculate the weight according to the measured angle using the weight corresponding to each representative value, as shown in Table 1 below, and add the weight to the measured angle.

The tilt angle calculation method described above can be changed, and the embodiments are not limited thereto.

Then, the controller 170 may determine whether the tilt angle exceeds the threshold angle (S112). If the tilt angle does not exceed the critical angle, the control unit 170 recommends a golf club corresponding to the calculated distance values (S116). The control unit 170 may display information on the golf club on the display unit 151 or may output information on the golf club through the sound output unit 152 by voice.

If there is no obstacle 200 obstructing the view or obstacle 200 obstructing the movement of the golf ball in the hazard HA, the user will not tilt the electronic device 100, so that the tilt angle does not exceed the threshold angle. The controller 170 may recommend a golf club having a corresponding distance according to the distance to each of the borders FB2a, FB2b, and FB1a located along the direction A1 from the current position 300. [

The memory 160 stores distance values corresponding to each of the different golf clubs, and information about the loft angle. Here, the information on the distance value may be stored in advance or may be completely stored by the user or may be partially input by the user and stored in the storage unit.

For example, the control unit 170 can receive the user's distance (for example, 130 m) to any one of the golf clubs (for example, 7 iron) from the user through the user input unit 130. Then, the control unit 170 may calculate the distance to the remaining golf clubs based on the inputted distance, and store the calculated distance in the memory 160. The control unit 170 calculates the distance for the remaining golf clubs based on the distance to the seventh iron, adjusts the distance for the iron by 10.00 m, adjusts the distance for the wedge by 20.00 m, Can be stored in the memory 160 as well.

The distance calculation method described above can be changed, and the embodiments are not limited thereto.

5, the distance from the current position 300 to the boundary FB2a is 9 m, the distance 610a from the current position 300 to the boundary FB2b is 108 m, the distance from the current position 300 to the boundary FB1a It is assumed that the distance 610b is 135 m.

When the golf ball 10 moves further along the direction A1 than the distance from the current position 300 to the boundary FB2a, the control unit 170 can move to the boundary HA from the current position 300, It is possible to recommend a golf club having a flying distance within a distance from the first golf club to the second golf club (FB2a). However, referring to Table 2, since there is no golf club having a distance of less than 9 m, the controller 170 does not recommend golf clubs corresponding to the distance from the current position 300 to the boundary FB2a.

When the golf ball 10 moves less than the distance 610a from the current position 300 to the boundary FB2b along the direction A1, it may be located at the hazard HA so that the control unit 170 controls the current position 300 ) To the boundary FB2b can be recommended. Referring to Table 2, since the golf clubs having a distance of 108 m or more are the golf clubs # 3 to # 9, the controller 170 controls the golf clubs corresponding to the distance 610a from the current position 300 to the boundary FB2b, 9 iron can be recommended.

When the golf ball 10 moves further along the direction A1 than the distance 610b from the current position 300 to the boundary FB1a, the control unit 170 can move the current position 300 ) To the boundary FB1a within the distance 610b. Referring to Table 2, the controller 170 determines the distance 610a from the current position 300 to the boundary FB2b because the golf club having a distance of less than 135m is the 7th to 9th irons and the PW, AW, 7 to 9 irons corresponding to the distances from the current position 300 to the boundary FB1a among the golf clubs corresponding to the golf clubs (i.e., the third to ninth irons).

That is, the controller 170 uses the boundaries FB2a, FB2b, and FB1a located along the direction A1 to move the golf ball 10 having the distance X1 at which the golf ball 10 can move in the golf course FA Recommended.

6, the distance from the current position 300 to the boundary FB2c is 8 m, the distance 610a from the current position 300 to the boundary FB2d is 142 m, the distance from the current position 300 to the boundary FB2e It is assumed that the distance 610b is 298 m.

When the golf ball 10 moves further along the A2 direction than the distance from the current position 300 to the boundary FB2c, the control unit 170 can move the boundary from the current position 300 to the boundary HA2, It is possible to recommend a golf club having a flying distance within a distance from the golf club head 2 to the second club head FB2c. However, referring to Table 2, since there is no golf club having a distance of less than 8 m, the controller 170 does not recommend golf clubs corresponding to the distance from the current position 300 to the boundary FB2c.

When the golf ball 10 moves less than the distance 620a from the current position 300 to the boundary FB2d along the A2 direction, the control unit 170 may move the current position 300 ) To the boundary FB2d can be recommended. Referring to Table 2, since the golf clubs having a distance of 142 m or more are the third to fifth irons, the controller 170 is a golf club corresponding to the distance 620a from the current position 300 to the boundary FB2d, To 5 irons can be recommended.

When the golf ball 10 moves further along the A2 direction than the distance from the current position 300 to the boundary FB2e, the control unit 170 moves to the boundary HA from the current position 300, It is possible to recommend a golf club having a distance within a distance up to the distance FB2e. Referring to Table 2, the controller 170 calculates the distance 620a from the current position 300 to the boundary FB2d because the golf club having a distance of less than 298m is the third to ninth irons and the PW, AW, 3 to 5 irons which correspond to distances from the current position 300 to the boundary FB2e among the golf clubs corresponding to the golf clubs (i.e., the third to fifth irons).

That is, the controller 170 uses the borders FB2c, FB2d, and FB2e located along the A2 direction to determine whether or not the golf ball 10 has a golf club having a distance X2 at which the golfer 10 can move in the golf course FA Recommended.

If there is an obstacle 200 blocking the field of view or an obstacle 200 obstructing movement of the golf ball in the hazard HA, the user will tilt the electronic device 100, so that the tilt angle exceeds the threshold angle. Then, the controller 170 calculates the distance of the golf club having the loft angle corresponding to the tilt angle (S114). At this time, the critical angle may be arbitrarily set, such as 5 degrees, 10 degrees, 15 degrees, and the like, and is not limited in this embodiment.

For example, the control unit 170 may calculate the distance of a golf club having a loft angle greater than a tilt angle stored in the memory 160. For example, As in Table 2, each of the golf clubs may have a different loft angle and distance.

The control unit 170 determines whether the distance of the golf club having the loft angle equal to or greater than the tilt angle is equal to or greater than the first boundary distance (S118). The first boundary distance is the distance to the point where the obstacle located in the direction in which the electronic device 100 faces ends. The point where the obstacle in front of the vehicle ends may be one of the boundaries detected in step S106. The control unit 170 can calculate the distance to the point where the obstacle located along the direction of the electronic device 100 ends, as the first boundary distance, using the course map information.

4 and 5, since the boundary FB2a at which the hazard HA starts and the boundary FB2b at which the hazard HA ends are located along the direction A1, the controller 170 controls the front obstacle 200 May be located within the hazard HA. Then, the controller 170 may determine the distance 610a from the current position 300 to the boundary FB2b as the first boundary distance.

Referring to FIGS. 4 and 6, since the boundary FB2c at which the hazard HA starts and the boundary FB2d at which the hazard HA ends are located along the A2 direction, the controller 170 controls the front obstacle 200 May be located within the hazard HA. Then, the controller 170 can determine the distance 620a from the current position 300 to the boundary FB2d as the first boundary distance.

If the distance of the golf club having the loft angle equal to or greater than the tilt angle exceeds the first boundary distance, the control unit 170 recommends the golf club (S120). Specifically, the controller 170 can recommend a golf club having a loft angle larger than the tilt angle and having a distance over the first boundary distance.

Referring to Figures 4, 5 and Table 2, a golf club having a loft angle greater than the tilt angle (40 degrees) is a 9 iron, PW, AW, SW wedge. Also, the golf clubs having a distance over the first boundary distance 108m are 3 to 9 irons. Therefore, the control unit 170 can recommend only the 9th iron having a loft angle larger than the tilt angle (40 degrees) and having a distance of 108 meters or more. The trail TR1 can move between the boundary FB2b and the boundary FB1a beyond the end TA of the obstacle 200 when the user hits the golf ball 10 using the 9 iron.

The control unit 170 outputs a warning message (S122) if the distance of the golf club having the loft angle equal to or greater than the tilt angle does not exceed the first boundary distance.

Referring to Figures 4, 6 and Table 2, a golf club having a loft angle greater than the tilt angle (40 degrees) is a 9 iron, PW, AW, SW wedge. Also, the golf club having a distance over the first boundary distance 142m is the third to fifth irons. Therefore, the control unit 170 can determine that there is no golf club having a loft angle larger than the tilt angle (40 degrees) and a distance over the first boundary distance 142m. The trajectory TR2 traps the hole HA in the boundary FB2d when the user tries to hit the golf ball 10 using the 9th iron having the longest distance while being able to pass the end TA of the obstacle 200, . The control unit 170 may output a warning message to guide selection of the other direction if the distance of the golf club having the loft angle equal to or greater than the tilt angle does not exceed the first boundary distance.

The electronic device 400 includes a case (for example, a frame, a housing, a cover, and the like) that forms an appearance. As shown, the electronic device 400 may include a front case 401, a middle case 402, and a rear case 403.

Hereinafter, embodiments related to a control method that can be implemented in the electronic device 400 constructed as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

11 to 13, a method of controlling the electronic device 100 according to an embodiment will be described.

Fig. 11 is a flowchart of a control method of an electronic device 400 according to another embodiment, and Figs. 12 and 13 show examples of calculating distances and angles corresponding to one direction in Fig. 4 according to the control method of Fig. FIG.

The description of the steps S200 to S208 in Fig. 11 is the same as and similar to the description of the steps S100 to S108 described in Fig. 3, so that a brief description will be given.

The position acquisition sensor 412 acquires the current position (S200). Then, the control unit 480 reads the course map information corresponding to the coordinates of the current position from the memory 460 (S202).

The azimuth sensor 414 measures the azimuth of the direction in which the electronic device 400 is oriented (S204). The control unit 480 detects whether there is a golf course boundary in the direction (azimuth angle direction) of the electronic device 400 (S206), and the control unit 480 calculates a distance from the current position to the boundaries (S208) do.

The tilt sensor 413 measures the tilt angle of the electronic device 400 and the distance measurement sensor 411 measures the straight distance from the electronic device 400 to the end of the obstacle S220. The end of the obstacle may include, but is not limited to, a portion of the obstacle aimed at by the user, such as the end of the tree, the mountain or the ridge of the hill.

12 and 13, if there is an obstacle 200 blocking the field of view or an obstacle 200 obstructing the movement of the golf ball in the hazard HA, the user can move the eyepiece HA1 of the electronic device 400, The user can aim the end TA of the obstacle 200 through the obstacle. Then, the tilt sensor 413 can measure the tilt angles a31 and a41 of the electronic device 400. [ When the user presses the fourth operation unit 430d while the end TA of the obstacle 200 is pointed at by the user through the eyepiece 421 of the electronic device 400, (D1, d2) from the obstacle 300 to the end TA of the obstacle 200 can be measured.

The control unit 480 calculates the height h11 from the electronic device 400 to the end TA of the obstacle 200 using the measured tilt angle and the straight line distance, The horizontal distance L11 to the end portion TA of the light emitting device 200 can be calculated. The control unit 480 may display the calculated value of the height h11 and the value of the horizontal distance L11 on the display unit 451. [

The control unit 480 controls the golf ball 10 and the obstacle using the calculated height h11 and horizontal distance L11 and the height h12 from the golf ball 10 to the electronic device 400 The height and the horizontal distance from the golf ball 10 to the end portion TA of the obstacle 200 can be calculated from the angle formed by the end portion TA of the obstacle 200 (hereinafter referred to as corrected tilt angle).

Referring to FIG. 12, the height h11 from the electronic device 400 to the end TA of the obstacle 200 can be calculated using the following equation (1).

Here, d1 is the straight line distance to the end TA of the obstacle 200 (distance to the end TA of the obstacle 200 measured by the distance measuring sensor 411), a31 is the distance from the electronic device 100 , And h11 is the height (difference in altitude) from the electronic device 100 to the end TA of the obstacle 200. [

Then, the height from the ground where the golf ball 10 is located to the end TA of the obstacle 200 can be calculated by adding h11 and h12. Here, h12 is the height from the golf ball 10 to the electronic device 400. h12 may be any value that can be set by the user's input. Or h12 may be a value obtained by measuring the vertical distance from the ground using the distance measuring sensor 413. [

On the other hand, the value of h12 may be ignored in the following equations. In this case, the control unit 480 controls the height h11 from the electronic device 400 to the end TA of the obstacle 200 to the height TA from the golf ball 10 to the end TA of the obstacle 200 .

The horizontal distance L11 from the electronic device 400 to the end TA of the obstacle 200 can be calculated using the following equation (2).

Here, the horizontal distance from the electronic device 100 to the end TA of the obstacle 200 is the horizontal distance.

When the horizontal distance L11 and the height h11 are calculated, the corrected tilt angle a32 can be calculated using the following equation (3).

Hereinafter, it is assumed that the corrected tilt angle a32 in FIG. 12 is 40 degrees and the corrected tilt angle a42 in FIG. 13 is 35 degrees.

Then, the control unit 480 can determine whether the corrected tilt angle exceeds the threshold angle (S112). If the corrected tilt angle does not exceed the threshold angle, the control unit 480 recommends a golf club corresponding to the calculated distance values (S216). The description of the step S216 is similar to that of the step S116, and a description thereof will be omitted.

If there is an obstacle 200 blocking the field of view or obstacle 200 obstructing movement of the golf ball in the hazard HA, the user will tilt the electronic device 400 to aim at the end TA of the obstacle 200 , The tilt angle increases, and thus the corrected tilt angle exceeds the threshold angle. Then, the control unit 480 calculates a trajectory corresponding to the corrected tilt angle (S214). At this time, the critical angle may be arbitrarily set, such as 5 degrees, 10 degrees, 15 degrees, and the like, and is not limited in this embodiment.

For example, the control unit 480 can read, from the memory 460, locus data of a golf club having a loft angle corresponding to the corrected tilt angle. As in Table 2, each of the golf clubs may have a different loft angle, and each of the golf clubs has a different trajectory. The control unit 480 can read the trajectory of the golf club having the loft angle larger than the corrected tilt angle value. The locus of the golf clubs will be described together with reference to Fig.

FIG. 14 is a diagram showing an example of locus data T1 to T7 of golf clubs. As shown in FIG. 14, each of the locus data T1 to T7 may be in the form of a function having a distance x on the x axis and a height y axis. 14 shows only the locus data T1 to T7 of the third to ninth irons, but the locus data may further include locus data of a driver, a wood, and a wedge in addition to an iron, but is not limited thereto.

Here, the locus data T1 to T7 are stored in advance in the memory 460 or may be modeled based on the value (distance information for any golf club) input by the user.

Also, the control unit 480 can calculate the distance of the golf club having the loft angle greater than or equal to the tilt angle stored in the memory 460. As in Table 2, each of the golf clubs may have a different loft angle and distance.

The control unit 480 determines whether the distance of the golf club having the loft angle equal to or greater than the tilt angle is equal to or greater than the first boundary distance (S218). The first boundary distance is the distance to the point where the obstacle at the front ends along the direction in which the electronic device 400 is facing. The point at which the obstacle at the front ends may be one of the boundaries detected at step S206.

If the distance of the golf club having the loft angle greater than the tilt angle exceeds the first boundary distance, the control unit 480 determines whether there is an obstacle in the trajectory of the golf club (S220). If there is an obstacle in the trajectory of the golf club, the control unit 480 recommends the golf club (S222). If there is an obstacle in addition to the trajectory of the golf club, the control unit 480 may output a warning message to guide selection of the other direction.

Specifically, the control unit 480 can determine whether an obstacle is located in the locus using the horizontal distance and height calculated in step S210.

Referring to Fig. 12, a golf club having a loft angle larger than the corrected tilt angle (40 degrees) is a 9 iron, PW, AW, SW wedge. Also, the golf clubs having a distance over the first boundary distance 108m are 3 to 9 irons. Therefore, the control unit 480 can determine whether there is an obstacle in the trajectory TR3 of the 9th iron, which has the loft angle larger than the tilt angle (40 degrees) and has the distance X3 over the first boundary distance 108m have.

The control unit 480 determines the horizontal distance L11 from the current position 300 to the end TA of the obstacle 200 and the height h11 from the current position 300 to the end TA of the obstacle 200 + h12), it is possible to determine whether the obstacle 200 is located in the trajectory TR3 of the 9th iron. In FIG. 12, the obstacle 200 is located in the locus TR3 of the No. 9 iron. Therefore, the control unit 480 can recommend the 9th iron to the user.

Referring to FIG. 13, the golf clubs having a loft angle larger than the corrected tilt angle (35 degrees) are 8th, 9th irons, PW, AW, and SW wedges. Also, the golf clubs having a distance over the first boundary distance 108m are 3 to 9 irons. Therefore, the control unit 480 controls the trajectory TR4 of the 8th iron having the loft angle larger than the tilt angle (40 degrees) and having the distance (X4, X5) over the first boundary distance 108m, It is possible to determine whether or not an obstacle exists in the locus TR3.

The control unit 480 determines the horizontal distance L21 from the current position 300 to the end TA of the obstacle 200 and the height h21 from the current position 300 to the end TA of the obstacle 200 + h22 can be used to determine whether the obstacle 200 is located within the locus TR4 of the 8th iron and the locus TR3 of the 9th iron. In Fig. 13, the obstacle 200 is located in addition to the locus TR4 of the 8th iron and the locus TR3 of the 9th iron.
