A golf practice machine having an effect of walking in a virtual field is provided to allow a user to walk in a distance corresponding to an actual one which a golf ball flies after it is hit by him/her, as if he/she practices a golf in an actual field, so as to increase his/her quantity of motion. A golf practice machine having an effect of walking in a virtual field includes: a screen(SC) having a target; many ball contact sensors(S1,S2,S3,S4), arranged in four corners of the screen; two detecting sensors(SL,SR), arranged in right and left net plates(M,M') of right and left lower sides of the screen respectively so as to detect a slice direction of a golf ball(B); a speed sensor(S5), arranged in the front of a tip(T) fixed to the frontal center of the screen so as to detect a speed of the golf ball; a PC, receiving a hitting result of the golf ball from the sensors so as to calculate a flying distance and a dropped position of the ball and to display a flying image thereof on the virtual field projected on the screen; and a switch member(1), having a right(1R) and a left switch(1L), and allowing a user to control a field screen easily by pushing the both switches with his/her both feet according to a moving direction of the virtual field.
