Hitting mat and virtual golf device

Abstract

The present invention relates to a virtual golf device and a hitting mat that may be used in the virtual golf device. The virtual golf device comprises a hitting mat on which a real golf ball for a user to hit is placed and which has a fairway area and a non-fairway area, a display part displaying a virtual golf course, a calculating part calculating a movement of a virtual golf ball corresponding to the real golf ball in the virtual golf course when the user hits the real golf ball, and a state change means changing the hitting mat to a first state or a second state, wherein if a direction of hitting the real golf ball is called a front, the first and second states are symmetrical to each other when viewed from the front.

What is claimed is: 
     
         1 . A hitting mat comprising:
 a fairway area; and   a non-fairway area,   wherein a real golf ball is placed on the fairway area or the non-fairway area when a user hits the real golf ball, and if a direction of hitting the real golf ball is called a front the fairway area is formed on both left and right sides and the non-fairway area is also formed on both left and right sides when viewed from the front.   
     
     
         2 . The hitting mat of  claim 1 , wherein a portion formed on the left side and a portion formed on the right side in the fairway area are symmetrical to each other. 
     
     
         3 . The hitting mat of  claim 1 , wherein a portion formed on the left side and a portion formed on the right side in the non-fairway area are symmetrical to each other. 
     
     
         4 . A virtual golf device comprising:
 a hitting mat on which a real golf ball for a user to hit is placed and which has a fairway area and a non-fairway area;   a display part displaying a virtual golf course;   a calculating part calculating a movement of a virtual golf ball corresponding to the real golf ball in the virtual golf course when the user hits the real golf ball; and   a state change means changing the hitting mat to a first state or a second state,   wherein if a direction of hitting the real golf ball is called a front, the first and second states are symmetrical to each other when viewed from the front.   
     
     
         5 . The virtual golf device of  claim 4 , wherein the hitting mat comprises a first hitting mat and a second hitting mat, and the state change means changes the hitting mat to the first state by exposing the first hitting mat and the hitting mat to the second state by exposing the second hitting mat. 
     
     
         6 . The virtual golf device of  claim 4 , wherein the state change means changes the hitting mat to the first state or the second state by rotating the hitting mat. 
     
     
         7 . A virtual golf device comprising:
 a hitting mat on which a real golf ball for a user to hit is placed;   a sensing means performing a sensing operation of sensing a state of the real golf ball at least one of when the user hits the real golf ball and after the user hits the real golf ball;   a display part displaying a virtual golf course and a virtual golf ball; and   a calculating part calculating a movement of the virtual golf ball in the virtual golf course by using a result of the sensing operation,   wherein a right-handed hitting area for a right-handed user and a left-handed hitting area for a left-handed user are provided on both sides of the hitting mat.   
     
     
         8 . The virtual golf device of  claim 7 , wherein the sensing means performs the sensing operation at a first position when the right-handed user is located at the right-handed hitting area and performs the sensing operation at a second position when the left-handed user is located at the left-handed hitting area. 
     
     
         9 . The virtual golf device of  claim 8 , wherein the sensing means moves to the first position or the second position by moving along a guide member. 
     
     
         10 . The virtual golf device of  claim 9 , wherein the sensing means comprises a sliding camera that moves along the guide member. 
     
     
         11 . The virtual golf device of  claim 7 , wherein the hitting mat has a fairway area and a non-fairway area, and if a direction of hitting the real golf ball is called a front the fairway area is formed on both left and right sides and the non-fairway area is also formed on both left and right sides when viewed from the front.
