When the user 104 moves to a position shown by a continuous line in the graphic, the display surface 101a of the image display device 101 turns its orientation so as to face the position on the user after moving. At this time, a computer graphics forming part 106 changes a three dimensional image to form so as to form a three-dimensional image seen from the position of the user 104 after moving. |
