FIGS. 5A to 5C are views illustrating an imaginary line and a vertical line displayed in the augmented reality display device for a golf field according to an embodiment of the present invention. Referring to 5a to 5c, various types of line types can be used when virtual lines and vertical lines are displayed in the display. In FIGS. 5A and 5B, the vertical lines between the two imaginary lines are indicated by solid lines and dotted lines, but the present invention is not limited thereto. The types of lines include solid lines, rounded dotted lines, rectangular dotted lines, dashed lines, long dashed lines, dashed-dotted lines, It may be a kind of line of various combinations. The line is not limited to a vertical line but may be similarly displayed in a virtual line representing the position of both feet and the virtual line appearing on the golf ball and may also be in the form of an arrow. Referring to FIG. 5C, the vertical line may be displayed to connect all of the two virtual lines, but a vertical line may be displayed as a partial area in a shorter length for the user wearing the display device to position the pair of feet. In FIG. 5C, the two legs are shown in contact with the imaginary line for positioning, but the present invention is not limited thereto. The imaginary lines displayed in the golf ball may be indicated by a partial length, or may be a combination of the two.

FIGS. 6A and 6B are views illustrating that the position of a vertical line displayed in the augmented reality display device for a golf field according to an embodiment of the present invention is changed and displayed between the first virtual area and the second virtual area.

6A and 6B, a user who wears the augmented reality display device for a golf field may have a plurality of golf clubs taken out for golf rounding and may have a combination of 14 or less clubs. The golf club may be a 1 wood (driver) to 5 wood, a 1 iron to 9 iron, a pitching wedge, a pitching sand, a sand wedge and a putter, So that the user can select a desired combination.

Each club is designed with different angles, for example the driver has a loft angle of 8 to 11 degrees when hitting a golf ball, 3 to 13 degrees to 15 degrees, 5 to 17 And the third iron is 19 degrees to 21 degrees, and the third to ninth irons increase in intervals of about 3 degrees to 4 degrees. The pitching wedge is 47 degrees and the sand wedge is 56 degrees. The length of each club is also different. For example, the driver is 45 inches, the third wood is 43 inches, the fifth wood is 42 inches, the third iron is 39 inches and the 9 iron is 0.5 Lt; / RTI > inches. The pitching wedge and the sand wedge are about 35 inches in length.

For example, in a driver, the stroke loft angle is small and the golf ball is the longest in the longest distance. Sand wedges are used for escaping golf balls in bunkers, and are used for accurate positioning of the golf ball rather than distance. Since the angle and length of each golf club are different, the positions of the feet to be placed on the golf ball in order to take the address posture must be different. For example, from the driver to the 5th wood, the golf ball comes close to the left foot and takes an addressing posture. Since the loft angle is very low, the user's position with respect to the golf ball is located closer to the left foot in order to increase the angle when hitting the golf ball during the swing in order to float the ball. In order to reflect such characteristics when the augmented reality display device for a golf field is worn, the positions of the vertical lines indicating the positions of the golf balls according to the selected clubs must match. Therefore, the position of the vertical line displayed in the augmented reality display device for a golf field can be displayed close to the left foot. Likewise, if you choose a 3 iron to 6 iron, the position of the vertical line will be displayed in the middle of the legs, and when you select the sand wedge from the 7 iron, the vertical line will be positioned closer to your right foot. For example, when using a sand wedge, when a wind blows to the front, a golf ball is positioned in the middle of both feet and then hit a lot of balls, which can be disturbed by the wind. The golf ball may be positioned close to the right foot as shown in FIG. 6B, thereby overcoming the above problem. The vertical line displayed on the augmented reality display device for golf field can adjust the position of the vertical line corresponding to the selected club on the basis of the above reason and the virtual area for positioning the pair of feet can be adjusted and displayed on the display.

FIG. 7 is an exemplary view showing a user wearing a golf field augmented reality display device according to an embodiment of the present invention, positioning a pair of feet in a virtual area in a correct position. 8 is an exemplary view showing that a display area of a virtual area disappears when a user wearing a golf field augmented reality display device according to an embodiment of the present invention moves away from a virtual area. FIG. 9 is a graph showing the relationship between the vertical distance of the first virtual line and the distance of the virtual area of the first virtual line and the second virtual line suitable for the selected club when the user wears the augmented reality display device for a golf field according to the present invention, Fig. FIGS. 10A to 10D are views showing a user wearing a golf field augmented reality display device according to an embodiment of the present invention and trying to put the golf course. FIG. 10B is a square stance, FIG. Fig. 10D is an illustration showing an imaginary line and a virtual area appearing in a closed stance. Fig.

Referring to FIGS. 7 to 10D, when a user wearing a golf field augmented reality display device looks down on a golf ball and both feet, a sensor operates to display augmented reality information. At this time, when the user inputs a club type to be used, two virtual lines and virtual regions suitable for the selected club are displayed (S210). The user can arbitrarily change the position of both feet within the virtual region to adjust the position, and the position of the virtual region is not changed at this time (S220). The user can position the feet so as to touch the virtual line and, if necessary, manually adjust the virtual area to change the position of the virtual area. The vertical distance between the hypothetical line appearing on the golf ball and the hypothetical line on which the foot is located in a parallel direction is indicated by a numerical value, so that the user can refer to the information for adjusting the distance appropriately (S310). If the user moves away from the virtual area, the virtual area information displayed on the display may disappear (S320, S330) (FIG. 8A). The disappearing virtual lines and virtual areas can be readjusted again. The sensor built in the device can again recognize the position of the changed golf ball and the position of the foot when the golf ball is out of one of the two virtual regions where the foot is located. The position of the virtual line and the virtual area that were initially displayed is displayed again according to the corrected posture of the user (FIG. 8B). Also, when changing the club that the user wants to use, by changing the club to be used for voice in the microphone or by using the input part arranged on the augmented reality display device for the golf field, the vertical distance between the imaginary lines The distance may be changed and displayed (S410). The longer the length of the club, the longer the distance between the virtual areas that place the foot, and vice versa, the shorter the length of the club you want to use, the shorter the distance between the virtual areas. After the user selects an appropriate club to place the golf ball at the target position, the user may attempt to put the golf ball after completing the address posture by repositioning the feet using the virtual line and virtual area information displayed as the augmented reality ).

Also, the spacing of the virtual regions may vary when a square stance, a closed stance, or an open stance posture is selected. For example, if you select a 7 iron and you switch to an open stance mode to strike the ball towards a greater distance, the distance between the two virtual areas may be farther apart than when selecting the closed stance mode. In the open stance posture, the in swing trajectory is drawn, and the slice or fade ball that the ball bends to the right appears and can be used in the approach, the short iron, and the bunker shot. In the closed stance, the club head is drawn in and out of the swing orbit, and a hook or a draw ball appears from right to left. When the three kinds of stances (square, open, closed) are selected, the information of the stance corresponding to the stances is displayed in the virtual area so that the user can position the foot in the virtual area to prepare the address posture.

FIG. 11 is a view illustrating a process of displaying a virtual line and a virtual area after a user wearing a golf field augmenting reality display device according to an embodiment of the present invention determines a direction to a target point in a field.

Referring to FIG. 11, for example, in a par 4 hole, the user first lands on the teeing ground to place the ball on the fairway, and then places the golf ball on the green, which is the target point, on the second hit. A user who wears augmented reality display device for a golf field takes a posture to hit the ball again to a position near the green hole cup. In order to determine the batting direction of the ball, the direction of the imaginary line connecting the ends of both balls is positioned so as to face the target point. When the user confirms the target point by turning his / her head, the imaginary line determining the correct direction among the two imaginary lines is a hypothetical line in which the legs are located. Therefore, when the imaginary line is extended, .

When the user gazes at the ball and fixes the virtual line and the vertical line displayed on the display, the user can set the virtual line and the vertical line to stay in the first displayed position at the fixed position even when the user moves his head or moves his or her face. It is possible to accurately take the posture when the first imaginary line and the vertical line are fixed based on the virtual line and the vertical line which are fixedly displayed when returning to the original posture after confirming the target point again. A compass sensor built into the device can also be used to lock the imaginary and vertical lines. After storing the direction from the current user's position to the target point, the ball can be addressed using the compass bearing stored to position both feet in the direction of the ball and parallel to the ball.
