Description

The present invention relates to a golf support device, a golf support method, and a golf support program, and in particular to a golf support device, a golf support method, and a golf support program that support improvement of a golf swing.

Generally, a golf ball (hereinafter simply referred to as "ball") is hit by swinging (moving) a golf club along a hitting line connecting a target point such as a cup and the ball so that the face of the golf club is perpendicular to the hitting line.
However, particularly in the case of beginner golfers with little golf experience, it is not rare for them to be unable to perform such a proper golf swing, and in such cases, there is a problem in that they are unable to hit the ball toward the target point.

To solve these problems, various technologies have been proposed to help improve golf swings. For example, Japanese Patent Application Laid-Open No. 2003-233666 discloses golf glasses.

The golf glasses of Patent Document 1 have a thin straight line drawn horizontally on the surface of the glasses lens, which is used to predict the ball's hitting line.
With this technology, a player can stand so that the straight line drawn on the eyeglass lenses overlaps with the ball and the target point (e.g., a cup), allowing the player to obtain a proper address, and by swinging a golf club along the straight line, the player can hit the ball toward the target point.

Utility Model Registration No. 3099890

However, the golf glasses described in Patent Document 1 have the problem that when swinging a golf club, the straight line drawn on the glasses lens must be aligned so that it overlaps with the ball and the target point, making the preparation steps before making a golf swing extremely cumbersome.

Furthermore, if a golfer performs this preparatory movement and then moves his or her head, for example by rotating around the neck, the straight line drawn on the eyeglass lenses will deviate from the ball and the target point, and the golfer will have to perform the same preparatory movement again, resulting in the problem of not being able to immediately swing the golf club on the correct trajectory.

The present invention was made to solve these problems, and aims to provide a golf support device, a golf support method, and a golf support program that enable a player to swing a golf club on the correct trajectory without the need for complicated preparatory actions.

The above problem is solved by the golf support device of the present invention, which comprises a transparent display means capable of displaying information superimposed on the golfer's field of view, an input means operable by the golfer, a detection means for detecting a shift in the golfer's field of view, a storage means for storing various information, and a control means for controlling the display means, and the input means is capable of inputting a hit line indicating the direction of impact to hit the ball, and the control means has a reference position setting section for setting the position of the field of view at the time of inputting the hit line as a reference position when the hit line is input by operating the input means, a hit line information registration section for storing the hit line input by operating the input means together with the reference position in the storage means, a field of view shift amount calculation section for calculating the amount of shift of the field of view based on the detection result detected by the detection means, and a display control section for moving and displaying a hit line image indicating the hit line on the display means according to the amount of shift of the field of view calculated by the field of view shift amount calculation section.

In the invention relating to the golf support device, it is preferable that the device includes a line image extending from the ball in the hitting direction.
In this case, it is more preferable that the hit line image further includes a second line image extending from the ball in a direction opposite to the hitting direction.

Furthermore, in the invention relating to the golf support device, it is preferable that the golf support device is smart glasses worn by a golfer.

The above problem is solved by a golf support method according to the present invention, which is a golf support method using a golf support device, the golf support device comprising: a transparent display means capable of displaying display information superimposed on a golfer's field of vision; an input means capable of inputting a hit line indicating a hitting direction in which the ball will be hit by an operation by the golfer; a detection means for detecting a shift in the golfer's field of vision; and a storage means for storing various information, the hit line being set by the golfer inputting a ball position of the ball before hitting and a target position of the ball after hitting using the input means from the same position in a direction opposite to the hitting direction of the ball, and a straight line connecting the ball position and the target position. The problem can also be solved by including a reference position setting step of setting the position of the field of view at the time of input as a reference position when the hit line is input by operating the input means, a hit line information registration step of storing the hit line input by operating the input means together with the reference position in the memory means, a field of view displacement calculation step of calculating an amount of displacement of the field of view based on the detection result detected by the detection means, and a display control step of moving and displaying a hit line image showing the hit line on the display means in accordance with the amount of displacement of the field of view calculated by performing the field of view displacement calculation step.

The above problem is solved by a golf support program according to the present invention, which is used in a golf support device, the golf support device comprising: a transparent display means capable of displaying display information superimposed on a golfer's field of view; an input means capable of inputting a hit line indicating a hitting direction in which the ball is hit by an operation by the golfer; a detection means for detecting a shift in the golfer's field of view; and a storage means for storing various information , the hit line being set by the golfer inputting a ball position of the ball before hitting and a target position of the ball after hitting using the input means from the same position in a direction opposite to the hitting direction of the ball, and a straight line connecting the ball position and the target position. The problem can also be solved by having a computer execute the following steps: a reference position setting step for setting the position of the field of view at the time of input as a reference position when the hit line is input by operating the input means; a hit line information registration step for storing the hit line input by operating the input means together with the reference position in the memory means; a field of view displacement calculation step for calculating the amount of displacement of the field of view based on the reference position based on the detection result detected by the detection means; and a display control step for moving and displaying a hit line image showing the hit line on the display means in accordance with the amount of displacement of the field of view calculated by performing the field of view displacement calculation step.

As described above, the golf support device, golf support method, and golf support program of the present invention have a relatively simple configuration, yet even beginners with little golf experience can immediately swing a golf club on the correct trajectory.

Note that in the following description, the left-right direction refers to the left-right direction when a golfer wearing the golf support device 1 is facing forward, and the up-down direction refers to the up-down direction in that state.

<Overall Configuration of Golf Support Device 1>
As shown in Fig. 1, the golf support device 1 according to this embodiment is a device that supports improvement of a golf swing, and is configured with smart glasses that can be worn by a golfer (see Fig. 6, hereinafter referred to as "golfer Gr"). The golf support device 1 corresponds to the "golf support device" described in the claims.

As shown in Figures 1 and 2, the golf support device 1 has a configuration similar to that of known smart glasses, such as a glasses frame 1A and a pair of transparent lenses 1B, 1B, and is also configured to include a central control unit 10 (CPU: Central Processing Unit), a memory unit 20, a detection unit 30, a display 40, and an input unit 50.
In the golf support device 1, a storage space 1C for storing electronic devices is formed in one of a pair of temples (the left temple in this embodiment) constituting the eyeglass frame 1A, and the storage space 1C contains the central control unit 10, memory unit 20, detection unit 30, as well as electronic devices such as a rechargeable battery. The central control unit 10, memory unit 20, detection unit 30, display 40, and input unit 50 correspond to the "control means", "memory means", "detection means", "display means", and "input means" described in the claims, respectively.

(Central control unit 10)
As shown in FIG. 2, the central control unit 10 reads various programs stored in the storage unit 20, performs predetermined arithmetic processing, and executes control to cause the display 40 to display a predetermined image, etc.
The central control unit 10 according to this embodiment includes a reference position setting unit 10A, a hit line information registration unit 10B, a visual field displacement calculation unit 10C, and a display control unit 10D. The reference position setting unit 10A, the hit line information registration unit 10B, the visual field displacement calculation unit 10C, and the display control unit 10D correspond to the "reference position setting unit," the "hit line information registration unit," the "visual field displacement calculation unit," and the "display control unit" described in the claims, respectively.

Although details will be described later, in this embodiment, the golfer Gr is configured to be able to input the ball hitting line as the hitting direction of the ball B that he or she is about to hit by operating the input unit 50 (see Figures 5(a) to (c)). A detailed explanation of inputting the ball hitting line will be given later.

In addition, when the ball line is input, the central control unit 10
The ball line and the position (reference position) of the field of view of the golfer Gr at the time of inputting the ball line are stored in the memory unit 20, and a ball line image BL showing the ball line is displayed on the display 40 (see FIG. 5(d)).
Thereafter, when the field of view of the golfer Gr changes, the amount of change is calculated, and the ball-hitting line image BL indicating the ball-hitting line is moved and displayed on the display 40 (see FIGS. 6 and 7).
The control performed by the central control unit 10 will be described in detail later.

(Reference position setting unit 10A)
The reference position establishment unit 10A is a part that performs control to set the field of view of the golfer Gr at the timing when the ball hitting line (see FIG. 5C) is input by operating the input unit 50 as the reference position.
Although details will be described later, in this embodiment, a change in the field of view of the golfer Gr (movement of the golf support device 1) is detected by a detection unit 30 consisting of a 6 DOF sensor (a sensor that detects movements in six directions, namely, the forward/backward direction X, the left/right direction Y, the up/down direction Z, the forward/backward direction X, the roll direction r, the pitch direction p, and the yaw direction y, see FIG. 3), and the amount of the change based on a reference position (the origin of coordinates "coordinate: 0") is calculated in real time.

(Hit line information registration unit 10B)
The hit line information registration unit 10B is a part that controls the storage in the memory unit 20 of the hit line input by operating the input unit 50, by linking it to the reference position set by the reference position setting unit 10A.

(Visual field shift amount calculation unit 10C)
The visual field displacement amount calculation unit 10C is a part that performs control to calculate the displacement amount of the visual field of the golfer Gr from the reference position stored in the storage unit 20 (the movement amount of the golf support device 1) in real time.
For example, if the field of view of the golfer Gr (golf support device 1) is displaced in the left-right direction X and rotated around an axis extending in the up-down direction Z, the amount of such displacement is calculated by dividing the reference position (the coordinate origin “coordinates”) by the reference position (the coordinates origin “coordinates”). The amount of displacement in the left-right direction X and the amount of rotational displacement in the yaw direction y based on the reference position (for example, "left-right direction X: 0→+10, yaw direction y: 0→+5") are converted into numerical values. This makes it possible to obtain the above information (see FIG. 3).

(Display control unit 10D)
The display control unit 10D displays on the display 40 (see FIG. 1 ):
A hit line image BL showing the hit line input by operating the input unit 50 is displayed (see FIG. 5(d)).
-This is the part that controls the movement and display of the hit line image BL according to the amount of displacement calculated by the field of view displacement calculation unit 10C when the field of view of the golfer Gr (golf support device 1) changes (see Figures 6 and 7).
More details will be described later, but in this embodiment, in addition to the above-mentioned hitting line image BL, a cursor image C (see Figures 5 (a) to (c)) used when the golfer Gr inputs the hitting line is also configured to be displayed under the control of the display control unit 10D.

(Memory unit 20)
The storage unit 20 is composed of a semiconductor memory such as a ROM (Read Only Memory) or a RAM (Random Access Memory),
A storage area for storing programs that control the operation of each of the reference position setting unit 10A, the ball line information registration unit 10B, the visual field shift amount calculation unit 10C, and the display control unit 10D,
It has a memory area for storing various information such as the ball line input by operating the input unit 50 and the reference position set by the reference position setting unit 10A. The program that controls the operation of each part of the reference position setting unit 10A, the ball line information registration unit 10B, the visual field displacement calculation unit 10C and the display control unit 10D corresponds to the "golf support program" described in the claims.

(Detection Unit 30)
The detection unit 30 is a device capable of detecting in real time the amount of change in the field of view of the golfer Gr.
In this embodiment, as such a device, a so-called 6DOF (Six Degrees Of Freedom) sensor (hereinafter, referred to as "6DOF sensor") consisting of a plurality of sensors such as an acceleration sensor and a gyro sensor is adopted.
Since the 6DOF sensor itself is now well known, detailed description will be omitted, but even in this embodiment, as shown in Fig. 3, it is possible to detect movements in six directions, namely, the forward/backward direction X, the left/right direction Y, the up/down direction Z, the roll direction r having an axis extending in the forward/backward direction X as its center of rotation, the pitch direction p having an axis extending in the left/right direction Y as its center of rotation, and the yaw direction y having an axis extending in the up/down direction Z as its center of rotation. That is, in this embodiment, the golfer Gr wears the golf support device 1 near his/her eyes (see Fig. 1), and the amount of change in the field of view is three-dimensionally detected in six directions.

(Display 40)
As shown in FIGS. 1 and 2, the display 40 is a transmissive display that displays a predetermined AR (Augmented Reality) image (in this embodiment, a "hit line image" and a "cursor image C") based on instructions from the display control unit 10D (see FIGS. 5 to 7).
As such a transmissive display, a known transmissive display, for example, a transmissive liquid crystal display (LCD) display, can be used.
The display 40 is disposed within the lens 1B or on the surface of the lens 1B. This allows the golfer Gr wearing the golf support device 1 to view the images displayed on the display 40 (in this embodiment, the "hit line image BL" and the "cursor image C") superimposed on the golfer Gr's field of vision (real image) (see FIGS. 5 to 7).

(Input unit 50)
The input unit 50 is a device for turning the power of the golf support device 1 on and off and for inputting various information.
Known input devices such as mechanical (push button) switches and touch panels can be used as the input unit 50. When a push button switch is used, it is possible to provide multiple switches at predetermined positions on the eyeglass frame 1B as shown in Fig. 1 (see "switches 50a to 50c" in Fig. 1).

When a plurality of switches 50a to 50c are provided as the input unit 50, as shown in FIG.
The switch 50a is used to turn the power supply on and off.
Switch 50b is a switch for inputting a hitting line (a switch for specifying the starting and ending positions of the hitting line) (see FIGS. 5(a) to 5(c));
Switch 50c is a switch for "determining" or "cancelling" the ball hitting line;
In the following, the explanation will be given on the assumption that a plurality of switches 50a to 50c are provided as the input unit 50. Note that, when a single switch is configured to be able to input two pieces of information, such as "confirm" or "cancel" of the ball line, like the above-mentioned switch 50c, it is possible, for example, to "confirm" when pressed once and to "cancel" when pressed twice consecutively.

<Control process in golf support device 1>
Next, the control process in the golf support device 1 will be described with reference to FIGS.
In the following, for the sake of convenience,
(1) The golf support device 1 is properly attached to the eyes of the golfer Gr (see FIG. 1 );
(2) When the power supply of the golf support device 1 is turned off, the ball-hitting line information regarding the ball-hitting line and the reference position stored in the memory unit 20 is erased from the memory unit 30 (see "Step S900" in FIG. 4).
(3) When the golf support device 1 is turned on, a cursor image C (an image for inputting a hitting line) is displayed on the display 40 (see FIG. 5( a )).
The above-mentioned controls (2) and (3) are merely examples, and may be modified as appropriate.

(Step S100)
As shown in FIG. 4, the control process in the golf support device 1 is mainly executed by the central control unit 10 (see FIG. 2), and starts with the process of step S100.
In step S100, the central control unit 10 performs a process of determining whether or not input of the hit line has been completed.

Before explaining the processing of step S100 by the central control unit 10, the procedure for inputting the ball's hitting line will be explained with reference to FIG. 5. FIG. 5 shows the state in which ball B is on the green on which the cup, which is the target point Tp, is placed.

In this embodiment, when the golf support device 1 is turned on, a cursor image C is displayed at a predetermined position (for example, the center) of the display 40 (see FIG. 5(a)).
The cursor image C is an icon for setting the start position and the end position of the hitting line. In this embodiment, as described above, the golf support device 1 can be turned on by pressing the switch 50a (see FIG. 1).

The golfer Gr can input the ball hitting line, for example, at a position in the opposite direction (hereinafter referred to as the "counter-hit direction") to the direction in which the ball B is intended to be hit (hereinafter referred to as the "hit direction"), that is, on the extension of the line connecting the ball B and the target point Tp (the "cup" in the example shown in Figure 5) in the counter-hit direction (see Figure 5(a)).

In this case, the golfer Gr moves to the extension of the line connecting the ball B and the target point Tp in the opposite direction to the hitting direction,
(1) First, move cursor image C to a position where it overlaps with ball B, and then press switch 50b (see FIG. 1) to input the starting position of the ball's hitting line (see FIG. 5(b)).
(2) Next, the cursor image C is moved to a position overlapping with the target point Tp, and then the switch 50b (see FIG. 1) is pressed to input the end position of the hitting line (see FIG. 5(c)).
(3) After that, the switch 50c (see FIG. 1) is pressed to confirm the ball's hitting line.
The ball's hit line can be input in the above manner. In this embodiment, the ball's hit line image BL can be displayed on the display 40 so as to be superimposed on the field of view of the golfer Gr (see FIG. 5(d)).

Such movement of the cursor image C can be configured to be performed automatically in response to a change in the field of view of the golfer Gr (movement of the golf support measure 1) detected by the detection unit 30. For example, when moving the cursor image C (downward) from the position shown in FIG. 5(a) to the position shown in FIG. 5(b), the golfer Gr can do this by moving his/her head backward around the neck as the center of rotation (see "Pitch direction p" in FIG. 3), in the same manner as the ball-hitting line image BL described below (see "Steps S500" to S700").

Movement of the cursor image C is not limited to being performed using the detection unit 30 as described above, but can also be performed by, for example, operating a switch. In this case, in addition to the switches 50a to 50c (see FIG. 1), a separate switch (e.g., a cross key) for moving the cursor image C can be provided.

When the above operation (2) is performed, i.e., when the end position of the hit line can be input, it is preferable to configure the device so that a provisional hit line image is displayed between the start position and the cursor image C (see FIG. 5(c)). This configuration allows the golfer Gr to easily visually grasp the direction of the hit line.

By performing the above-mentioned operations (1) to (3) on an extension of the line connecting the ball B and the target point Tp in the opposite striking direction, as in this embodiment, it is possible for the golfer Gr to more accurately draw (input) the desired hitting line of the ball B.
It should be noted that such input of the hitting line can be performed in the same manner as the above (1) to (3) even in cases where it is difficult or impossible to see the target point Tp (cup) (for example, the tee ground of a long hole). In this case, in the above operation (2), the intended ball position after hitting that the golfer Gr desires (for example, the center point of the fairway) can be input as the end position of the hitting line.

As shown in FIG. 4, if the central control unit 10 determines that the above operation (3) has been completed, it proceeds to step S200, and if it determines that the above operation (3) has not been completed, it repeats the process of step S100.

(Step S200)
In step S200, the central control unit 10 performs a reference position setting process. This process is mainly performed by the reference position setting unit 10A (see FIG. 2) of the central control unit 10. The reference position setting process corresponds to a "reference position setting process" and a "reference position setting step" described in the claims.

Specifically, the central control unit 10 performs processing to set the position of the golf support position 1 (the position of the golfer Gr's field of view) at the time when the ball line is input (the time when the processing in step S100 above is judged to be ``YES'') as the reference position (coordinate origin ``Coordinate: 0'' (``Each of the coordinates of the forward/backward direction X, left/right direction Y, up/down direction Z, roll direction r, pitch direction p, and yaw direction y: 0'')).
After performing the reference position setting process, the central control unit 10 advances the process to step S300.

(Step S300)
In step S300, the central control unit 10 performs a hit line information registration process. This process is mainly performed by the hit line information registration unit 10B (see FIG. 2) of the central control unit 10. The hit line information registration process corresponds to the "hit line information registration process" and the "hit line information registration step" described in the claims.

Specifically, the central control unit 10 performs a process of storing the ball line input in the process of step S100 in the memory unit 20 (see FIG. 2) together with the reference position set in the process of step S200.
After performing the ball line information registration process, the central control unit 10 advances the process to step S400.

(Step S400)
In step S400, the central control unit 10 performs a process of displaying a hit line image. This process is mainly performed by the display control unit 10D of the central control unit 10 (see FIG. 2).
Specifically, in step S400, the central control unit 10 performs a process of displaying a hit line image BL indicating the hit line on the display 40 along the hit line input in the processing of step S100 (see FIG. 5(d)).

As shown in Fig. 5(d), the hit line image BL according to this embodiment has a line image (a line image extending from ball B in the hitting direction, hereinafter referred to as "first line image BL1") connecting the starting position of the hit line ("ball B" in Fig. 5) and the target point Tp, and a line image (hereinafter referred to as "second line image BL2") extending from ball B in the opposite hitting direction. Note that the first line image BL1 and second line image BL2 correspond to the "line image" and "second line image" respectively as described in the claims.
After performing the hit-ball line image display process, the central control unit 10 advances the process to step S500.

(Step S500)
As shown in FIG. 4, the central control unit 10 performs a process of determining whether or not the field of view of the golfer Gr has changed in step S500.
Specifically, the central control unit 10 determines whether or not the golf support device 1 has been moved.

As described above, in this embodiment, the movement of the field of view of the golfer Gr (golf support device 1) is detected using the detection unit 30 (6DOF sensor, see Figures 2 and 3). That is, when the movement of the golf support device 1 is detected by the detection unit 30, for example, when movement from the reference position ("coordinate: 0") to "forward/rear direction X: +10" is detected, or when movement from "forward/rear direction X: +10, pitch direction p: 0" to "forward/rear direction X: +15, pitch direction p: +5" is detected, the central control unit 10 performs processing to determine that the field of view of the golfer Gr has shifted. On the other hand, when the movement of the golf support device 1 is not detected by the detection unit 30, the central control unit 10 determines that the field of view of the golfer Gr has not shifted.

If the central control unit 10 determines that the field of view of the golfer Gr has shifted, it proceeds to step S600, and if it determines that the field of view of the golfer Gr has not shifted, it repeats this process.

(Step S600)
In step S600, the central control unit 10 performs a visual field displacement calculation process. This process is mainly performed by the visual field displacement calculation unit 10C (see FIG. 2) of the central control unit 10. The above-mentioned visual field displacement calculation process corresponds to the "visual field displacement calculation process" and the "visual field displacement calculation step" described in the claims.

For example, when the detection unit 30 detects that the golf support device 1 has moved from "forward/backward direction X: +10, pitch direction: 0" to "forward/backward direction X: +15, pitch direction p: +5," the central control unit 10 performs a process of calculating a numerical value such as "forward/backward direction X: +10 → +15, pitch direction p: 0 → +5" as the amount of change in the field of view of the golfer Gr.
After performing the visual field shift amount calculation process, the central control unit 10 advances the process to step S700.

(Step S700)
In step S700, the central control unit 10 performs a display control process. In this embodiment, this process is mainly performed by the display control unit 10D of the central control unit 10. Note that the display control process corresponds to a "display control process" and a "display control step" described in the claims.

Specifically, the central control unit 10 performs a process of moving and displaying the hit line image BL displayed on the display 40 in accordance with the amount of displacement of the golfer Gr's visual field calculated in the visual field displacement calculation process in step S600.
For example, if the value calculated in the visual field shift calculation process in step S600 is "forward/backward direction X: +10→+15, pitch direction p: 0→+5," the central control unit 10 controls the display position of the hit line image BL to be changed from "forward/backward direction X: +10, pitch direction p: 0" to "forward/backward direction X: +15, pitch direction p: +5." As a result, when the golfer Gr looks at the ball B in a normal state with his/her line of sight facing forward (hereinafter referred to as the "normal viewing state"), the hit line image BL shown on the display 40 is displayed superimposed on the ball B in the direction of the hit line input in the process in step S100 (see FIGS. 6 and 7).

As a result, the golfer Gr can relatively easily hit the ball B toward the target point Tp, which is the cup, by moving the golf club Gc (making a golf swing) along the hitting line image BL that is displayed superimposed on the ball B (see Figures 6 and 7).
In addition, even if the golfer Gr, for example, moves his/her head left or right around his/her neck as the center of rotation after getting into the address position to hit the ball B, causing the ball B to go out of view, the golfer Gr can again get into the address position to hit the ball B (move the neck to its original position) and the hit line image BL can be superimposed on the ball B.

Thus, in this embodiment, when the golfer Gr looks at the ball B in a normal viewing state, regardless of the viewing position, the hit line image BL is superimposed on the ball B in the direction of the inputted hit line (see Figures 6 and 7), so that even a beginner with little golf experience can immediately make a golf swing on the correct trajectory.
After performing the above-mentioned display control process, the central control unit 10 advances the process to step S800.

(Step S800)
In step S800, the central control unit 10 performs a process of determining whether or not an operation to turn off the power has been performed.
Specifically, the central control unit 10 judges whether or not the switch 50c (see FIG. 1) for turning the power on and off has been pressed.
If the central control unit 10 determines that an operation to turn off the power has been performed, it proceeds to step S900, and if it determines that an operation to turn off the power has not been performed, it proceeds to step S500.

(Step S900)
In step S900, the central control unit 10 performs a process of erasing the hit line and the reference position stored in the memory unit 20 in the hit line information registration process in step S300 (hit line information erasure process).
After performing the ball line information erasing process, the central control unit 10 advances the process to step S1000.

(Step S1000)
In step S1000, the central control unit 10 performs a process of turning off the power.
As a result, in this embodiment, when the golfer Gr subsequently turns on the power, the processing from step S100 onwards is started anew.
After performing the process of turning off the power, the central control unit 10 ends this control process.

As described above, in this embodiment, after inputting the hitting line of ball B, when the ball B is viewed, the hitting line image BL (AR image) showing the hitting line is displayed superimposed on the field of view of the golfer Gr (ball B) in the direction of the input hitting line, regardless of the position from which the ball B is viewed (see Figures 6 and 7). Therefore, according to this embodiment, when hitting the ball B, the hitting line image BL is displayed superimposed on the actual ball B without the need for complicated preparatory actions as in the above-mentioned conventional technology (Utility Model Registration No. 3099890), so even a beginner with little golf experience can immediately swing the golf club Gc on the correct trajectory.

In addition, in this embodiment, the ball hit line is input from the direction opposite to the direction of impact of the ball B by operating the input unit 50, and is configured to include a line extending from the ball B in the direction of impact (see FIG. 5(c)). Therefore, in this embodiment, it is possible for the golfer Gr to input the ball hit line he or she desires with high accuracy.

Furthermore, in this embodiment, the hitting line image BL includes a first line image BL1 extending from the ball B in the hitting direction (see Figures 6 and 7), making it possible to easily grasp the hitting direction of the ball B.
In addition, the hitting line image BL in this embodiment includes, in addition to the first line image BL1, a second line image BL2 extending from the ball B in the counter-impact direction (see Figures 6 and 7), so that the golf club Gc can be swung in a more appropriate trajectory.

Furthermore, in this embodiment, since the golf support device 1 is configured as smart glasses (see FIG. 1), even if the golfer Gr wears the golf support device 1, it can be easily carried around like regular glasses such as sunglasses, and there are no problems such as the device interfering with play when playing golf.

In this embodiment, smart glasses are used as the golf support device 1, but other devices equipped with a display, such as goggle-type devices (head mounted displays (HMDs)), may also be used.

In addition, in this embodiment, a 6DOF sensor is used as the detection unit 30 that detects the change in the field of view of the golfer Gr, but other sensors and other detection methods can also be adopted.
Other detection methods include, for example:
The golf support device 1 is provided with an imaging means (e.g., a camera) for capturing an image in the field of view of the golfer Gr.
- Image recognition of feature points (e.g., a ball B and/or a target point Tp such as a cup) in an image captured by the imaging means;
Detecting a change in the field of view of the golfer Gr based on the positions and angles of the image-recognized feature points,
Examples of such a method include a method using a known image recognition technique.

Furthermore, in this embodiment, in order to make it easier to understand the invention, a golf support device 1 of a type that does not take into account the line of sight of the golfer Gr has been described as an example, but it is also possible to take this into account.
Such a configuration is, for example,
The golf support device 1 is provided with a known imaging means (e.g., a camera) for capturing an image in the line of sight of the golfer Gr.
In addition to the detection result detected by the detection unit 30, the display position of the hit line image BL displayed on the display 40 is controlled to be shifted by taking into account the line of sight imaged by the imaging means.
This can be realized by configuring in this way. With this configuration, the hit-ball image line BL can be displayed superimposed on the ball B more naturally.

In addition, in this embodiment, the hit line image BL is displayed in a position overlapping with the ball B (see Figures 6 and 7), but it can also be displayed in a position that does not overlap with the ball B, provided that it is in the direction of the input hit line.

In addition, in this embodiment, one hit line image BL is displayed (see Figures 6 and 7), but it is also possible to display multiple hit line images, for example, a hit line image displayed in a position overlapping with ball B and a hit line image displayed in a position not overlapping with ball B (a total of two hit line images), provided that the direction is the same as the input hit line.

The above describes an embodiment of the invention made by the inventor, but the present invention is not limited to the descriptions and drawings that form part of the disclosure of the present invention according to this embodiment. In other words, it should be added that all other embodiments, examples, and operational techniques made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
