Claim 1:
2. The screen soccer system of claim 1, wherein the first footstep sensing device or the second footstep sensing device includes:
a data communicator configured to transmit or receive data to or from the system server;
a sensing part including a vibration sensor, a pressure sensor, or an optical sensor; and
a measurement controller configured to measure the footstep information of the user through the sensing part and transmit the footstep information to the system server through the data communicator and configured to control the sensing part to stop measuring when footstep end information calculated by the system server using the received footstep information is received through the data communicator, or configured to measure the gravity center movement information of the user through the sensing part, transmit the gravity center movement information to the system server, and control the sensing part to stop measuring when kicking end information calculated by the system server using the received gravity center movement information and image information received from the image sensing device is received through the data communicator.
