The virtual golf device according to an embodiment of the present invention includes the image providing unit 1070. The image providing unit 1070 serves to provide a putting guide image to a user by illuminating the putting guide image on an area other than the screen of the screen golf field equipped with the virtual golf device.
A putting guide may be provided to a user in a putting step and shows play information about putting. Referring to
The putting guide informs the user of putting information that can lead to a successful hole-in in consideration of the topographic characteristics (inclination direction, inclination degree, etc. of an area between the virtual golf ball and the hole cup) of the green area. For example, as shown in
According to the prior art, the putting guide is provided on a virtual golf course displayed on the screen. In contrast, in the virtual golf device according to an embodiment of the present invention, the putting guide image can be displayed at an area other than the screen through the image providing unit 1070. In detail, the putting guide image can be provided at the floor of a place (screen golf field) where the virtual golf device is installed. The putting guide image can be provided separately from an image displayed on the screen, and can be provided at or near a place where the user is located when playing screen golf. In detail, referring to
When a putting guide is provided as an image in the screen as in the prior art, the putting guide in the screen is not easily recognized by the user because the screen is somewhat spaced apart from the user's hitting position. In addition, because the user has to put a golf ball on the hitting plate on the floor but the putting guide in the screen is displayed on the front screen, a plane on which the putting guide in the screen is displayed and the floor on which the user actually rolls the golf ball are different planes. For example, if the floor surface is an xy plane, the front screen becomes an yz plane. Because the user needs to putt a golf ball placed on the xy plane in accordance with the direction of the putting guide displayed on the yz plane, the direction of the putting guide in the screen is substantially different from the direction in which the user rolls the actual golf ball. However, when the putting guide image is provided on the bottom surface of the screen golf field as in the present embodiment, the aforementioned problems can be solved.
Referring to
As shown in
Examples in which a putting guide is provided in the form of any one of the arrow, the predicted trajectory of a golf ball, and the target spot have been described above, but the putting guide may be displayed as a combination of at least two or more of the aforementioned forms, or may also be displayed in other forms not described herein.
Referring to
As described above, according to an embodiment of the present invention, the putting guide image can be provided at the hitting mat and/or the middle area. In addition, according to the present embodiment, the putting guide can be displayed on the screen as in the related art. Therefore, the putting guide may be provided on the screen and/or the floor of a place (e.g., a screen golf field) where the virtual golf device is installed, and a user can select whether to be provided with a screen/floor putting guide through a menu on the screen. For example, as shown in
(1) No putting guides are provided on either the screen or the floor.
(2) A putting guide is provided only on the screen.
(3) A putting guide is provided only on the floor.
(4) Putting guides are provided on both the screen and the floor.
There may be several ways to provide a putting guide image. Some methods will now be described.
Referring to
Referring to
The target point P and the predicted path T are related to an assumption that the middle area corresponds to the virtual golf course on the screen and has the topographical characteristics identical to that of the virtual golf course. The putting guide PG indicates a direction in which an actual golf ball is to be rolled, and, when a golf ball is rolled in the direction indicated by the putting guide PG a virtual golf ball on the screen first rolls in the direction indicated by the putting guide PG and then bends to roll in an inclined direction according to the topographical characteristics (slope of a green area in the virtual golf course) of the virtual golf course on the screen, whereas, because the bottom surface of an actual screen golf field is flat, a putted golf ball is less likely to bend under the influence of the bottom surface. Therefore, a trajectory of the putted actual golf ball on the bottom surface of the screen golf field is different from a trajectory of the virtual golf ball on the screen image. According to the present embodiment, the predicted path T represents a trajectory by the movement of an actual golf ball putted in the putting direction (the direction indicated by the putting guide PG) when it is assumed that the bottom surface of the screen golf field has the same slope as a virtual golf field on the screen, and the target point P represents a location that may be reached when the golf ball moves along the predicted path T. In other words, the target point indicates a point corresponding to the hole cup on the screen in the middle area when it is assumed that the middle area has topographical characteristics corresponding to those of the virtual golf course on the screen. When an image of the target point P and the predicted path T are displayed, the topographical characteristics of the virtual golf course on the screen may be expressed to some extent on the bottom surface of the screen golf field, and the user can feel a reality of putting in real golf.
