Virtual golf device and virtual golf system providing putting information

Abstract

The present invention relates to a virtual golf device and virtual golf system providing various putting information. The virtual golf device comprises a hitting mat on which an actual golf ball is placed and an image providing means that provides a putting information image on the hitting mat or near a user hitting the actual golf ball, wherein the putting information comprises a swing trajectory image that shows a swing trajectory during putting.

1 . A virtual golf device comprising:
 a hitting mat on which an actual golf ball is placed; and   an image providing means that provides a putting information image on the hitting mat or near a user hitting the actual golf ball,   wherein the putting information comprises a swing trajectory image that shows a swing trajectory during putting.   
     
     
         2 . The virtual golf device of  claim 1 , wherein the swing trajectory image comprises a moving image of a golf club or a guider corresponding to the golf club. 
     
     
         3 . The virtual golf device of  claim 2 , wherein in the swing trajectory image, the moving direction and/or speed of the golf club or the guider represents a putting direction information and/or a putting force information. 
     
     
         4 . The virtual golf device of  claim 2 , wherein the swing trajectory image further comprises a line showing a path of the golf club or the guider in motion in addition to the moving image of the golf club or the guider. 
     
     
         5 . The virtual golf device of  claim 1 , wherein the swing trajectory of the swing trajectory image represents at least part of multiple swing steps of putting. 
     
     
         6 . The virtual golf device of  claim 5 , wherein the multiple swing steps comprise a backswing step, an impact step after the backswing step until impacting a golf ball and a finish step after the impact step. 
     
     
         7 . The virtual golf device of  claim 1 , wherein the swing trajectory in the swing trajectory image comprises a plurality of different swing trajectories. 
     
     
         8 . The virtual golf device of  claim 1 , wherein the image providing means further provides an image showing the swing trajectory of the swing trajectory image and an actual swing trajectory of a user's putting during putting together after the user's putting. 
     
     
         9 . The virtual golf device of  claim 1 , wherein the swing trajectory image is provided so that the swing trajectory in the image is spaced apart from or overlaps with the actual golf ball on the hitting mat. 
     
     
         10 . A virtual sport system comprising:
 a service device; and   at least one virtual golf device communicatively connected to the service device,   wherein the virtual golf device comprises a hitting mat on which an actual golf ball is placed and an image providing means that provides a putting information image on the mat or near a user hitting the actual golf ball during a putting step, the putting information image comprising a swing trajectory image that shows a swing trajectory during putting.
