<p>PROBLEM TO BE SOLVED: To provide a spatial coordinate input device capable of reflecting inputted spatial coordinates and displaying a virtual object that is faithfully reproduced in a virtual three-dimensional space. SOLUTION: Initialization including screen position setting, etc., is performed (100), the entire correction array which corrects an error between a real spatial position (real coordinate values) in the entire real space and a spatial position (magnetic coordinate values) magnetically detected by a position sensor is calculated (102), a viewpoint correction array which corrects an error between the real coordinate values and the magnetic coordinate values in a viewpoint space is calculated (104), an operation correction array which corrects an error between the real coordinate values and the magnetic coordinate values in an operation space is calculated (106), a buffer area (blend area) to the viewpoint space and the operation space is set and correction values in the buffer area are calculated (108), an error between an actual spatial position and the spatial position detected by a position sensor is corrected (space correction) on the basis of the respective calculated values, and a stereoscopic image is displayed on a virtual space (110).</p> |
