<p>PURPOSE:To easily point a specific target object by making it easy to grasp coordinates in a depth direction in a three dimensional space without making a display screen complicate. CONSTITUTION:The cursor controller consists of a reference object display part 18 which displays a reference object of size corresponding to the depth- directional coordinate values of the same position at the specific position in the three-dimensional space, an indicated object position decision part 12 which decides which direction (depth direction) a position optionally indicated through an input device is moved in, an indicated object enlargement/reduction part 14 which enlarges or reduces the size of the indicated object corresponding to the coordinate values of the indicated position in the depth direction, and an indicated object display part 16 which displays the indicated object enlarged or reduced by the indicated object enlargement/reduction part 14 on a display device.</p> |
