<P>PROBLEM TO BE SOLVED: To intuitively manipulate an object placed in a virtual three-dimensional space by means of a posture of a manipulation device. <P>SOLUTION: A directional difference representing a difference between the posture direction of an object 64 in a virtual three-dimensional space and a gaze direction used when generating a spatial image representing the virtual three-dimensional space is calculated, and the object 64 is made to move in a direction according to directional difference information and posture information on a manipulation device 42, and to be changed in its posture, and so on. <P>COPYRIGHT: (C)2008,JPO&INPIT |
