<p><P>PROBLEM TO BE SOLVED: To provide a three-dimensional instruction input system, a three-dimensional instruction input device, a three-dimensional instruction input method and a program capable of continuing an input operation without loading a surplus burden onto a user, even when an instruction position by the user comes out of a set input range. <P>SOLUTION: In this three-dimensional instruction input system 1a, an image photographing device 12a photographs light from a point light source, when the user operates a position instruction device 11a having the point light source to indicate an instruction position on the input range set within a prescribed three-dimensional space, an instruction position computing means 136 computes the instruction position, based on an image data photographed therein, and an instruction mark is displayed in a position corresponding to the instruction position on a screen of a display part 134. When the instruction position comes out of the input range, an input range changing means 137 changes a position of the input range to include the coming-out instruction position within the input range. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
