METHOD AND UNIT FOR CONTROLLING VIRTUAL SPACE AND RECORDING MEDIUM WITH RECORDED VIRTUAL SPACE CONTROL PROGRAM

PROBLEM TO BE SOLVED: To provide a moving means which allows a person who experiences a virtual space to move a body in the virtual space without any feeling of physical disorder. SOLUTION: A vector computation part 14 computes an upper body approximate vector showing the tilt of an upper half body according to position information on the positions of sensors 21 to 23 put on a head, a neck, and a waist and an arm approximate vector according to position information on the positions of sensors 24 to 26 put on a shoulder, an elbow, and a hand. A tilt computation part 15 and a moving speed computation part 16 compute the speed corresponding to the tilt and value of the upper half body approximate vector. A force direction computation part 19 computes the direction of a force from an arm approximate vector. A decomposition part 20 and a decision part 21 determine whether or not the body is moved according to the strength and direction of the force. According to the decision result, a display part 22 instructs an image display device 3 to display an image.
