To provide a virtual connection operating object capable of realizing high- level form and movement.

An ancestor A is provided with a fixed parameter [UA] (position and rotation) with a coordinate origin O as a reference and descendants B to D are provided with fixed parameters [UB-D ] with a connection destination solid-state local coordinate origin (o) as a reference. Then, a state parameter [S(i)] is found by multiplying the solid-state parameter [U(i)] tp a state parameter [S(i-1)] of a reference coordinate, the positions and rotations of universal coordinates of descendants B and D are displayed on a screen while starting it from the anscetor A, operation is returned to C, and similar processing is performed as a whole solid. As for the deformation of an object corresponding to physical environments, the object is turned around the prescribed axis (o), a weighted average rotational difference vector <RAV> is found by a rotational difference vector <RA-C> and parameter information gA-C showing the degree of difficulty and easiness for displacement, and that vector is turned around the universal coordinate origin O just for <RA>. The weighted average position differential vector <MAV> is found from the position differential vector <MA-C> before the rotation and the parameter information g and the reversely rotated object is reversely parallelly moved just for <MAV>.
