To enable a user to easily and intuitively operate prescribed information in a three-dimensional virtual space.
A main control part 12 sets the first coordinate system of an actual space 31 on the basis of prescribed information of an actual object 14, and sets the second coordinate system of the three-dimensional virtual space 32 corresponding to the actual space 31 on the basis of the first coordinate system. When the user arranges an input part 11 with a prescribed position and angle in the first coordinate system with the actual object 14 as an index, an object 33 is arranged in the three-dimensional virtual space 32, and an image corresponding thereto is displayed on a display part 13. This device and method are applicable to a personal computer.
