3次元視点位置・視線方向の入力装置

Abstract

<P>PROBLEM TO BE SOLVED: To observe an object in a three-dimensional space from an optional point of view and to simultaneously direct the point of view in an optional direction in the three-dimensional space. <P>SOLUTION: A three-dimensional view position/view direction input device 1 performs input to observe an object for observation in the three-dimensional space displayed on a display from the optional view position. The three-dimensional view position/view direction input device 1 is provided with a view position change input means 2 for performing input to change the view position while changing the view position so that a visual line is directed to the object for observation in the three-dimensional space and a view direction change input means 3 for performing input to change the visual line direction from the view position without changing the view position. <P>COPYRIGHT: (C)2006,JPO&amp;NCIPI
