Description:

TECHNICAL FIELD

The present invention relates to a screen golf system and a method of displaying a striking state and, more particularly, to a screen golf system in which impact sensors located near a golf ball sense a position where the golf club of a golf player strikes a blow against the ground and strike force exerted to the ground when the golf player swings and the detected position and strike force are outputted in order for the golf player to see the detected position and strike force so that information about a striking state necessary to embody various ball diversion techniques can be provided to the golf player.
