Claim Text:
1. A 3-dimensional coordinate specifying device characterized by the fact that said device comprises: a standard plane setter configured to set at least one optional standard flat plane, wherein when a displaying object displayed in a 3-dimensional space having an XYZ coordinate system has a flat plane, which is not parallel to any of an XY plane, a YZ plane and a ZX plane of the XYZ coordinate system, the standard flat plane is parallel to the flat plane, while when the displaying object has no flat plane, the standard flat plane is perpendicular or parallel to a coordinate plane; a standard point determiner configured to determine an optional point on the standard flat plane, set by said standard plane setter, as a standard point; a light beam emitter configured to emit an imaginary light beam at an optional angle from the standard point determined by said standard point determiner; a point specifier configured to specify an optional point on the imaginary light beam emitted by said light beam emitter; and a coordinate calculator configured to calculate 3-dimensional coordinates of the point specified by said point specifier.
