ABSTRACT:
In a system for inputting image and command using a three-dimensional mouse, a transmitting dipole antenna (13) is movable in an out side real space which responds to a virtual space to radiate an electromagnetic wave. A radiation controlling switch (15) controls the transmitting dipole antenna to radiate the electromagnetic wave. A hologram data collecting circuit (17) receives the electromagnetic wave and collectes hologram data in response to the electromagnetic wave. A data processing unit (18) operates an expression in response to the hologram data to produce an image in the virtual space that responds to the transmitting dipole antenna. The expression defines an analogous expression which represents an analogous intensity of a wave which is generated by the hologram data. A movement distance operating unit (19) operates a movement distance of the transmitting dipole antenna while the transmitting dipole antenna radiates the electromagnetic wave.
