PROBLEM TO BE SOLVED: To provide a spatial graphic input device capable of inputting a spatial graphic so that an inputted spatial graphic can not come apart in the direction of a visual line. SOLUTION: A stereoscopic image by the image data of a virtual object is displayed until graphic inputting is started (200 to 204), and the magnetic coordinates of a position input device and the position of an operator OP are read (206) and converted into the coordinate values of a real space (208). Next, a viewpoint position is operated, a visual line is set, subsequently, an input plane that passes through a coordinate point indicated by the visual line direction as a normal line is generated (210 to 214), input coordinates are limited by the input plane and the coordinates are outputted (216 and 218). Then, it is possible to perform stable inputting without making blurring in a depth direction because only coordinate components on the input plane with the visual line direction defined as a normal line can undergo coordinate inputting. |
