PROBLEM TO BE SOLVED: To suppress misoperation and to attain speedy input by changing an image in the horizontal, longitudinal, or depth direction of a display corresponding to (x)-axial, (y)-axial, or (z)-axial operation in a three-dimensional actual space. SOLUTION: A two-dimensional menu in a starting layer is a menu for selecting a genre. Then different three-dimensional menus are prepared by genres as two-dimensional menus of low order. When an operation means is operated along the (x) axis among the (x), (y), and (z) axes, the image is changed in the horizontally direction of the display. Further, when the operation means is operated along the (y) axis, the image is changed in the longitudinal direction of the display. Furthermore, when the operation means is operated along the (z) axis, the image is changed in the depth direction. Consequently, a desired image is speedily and securely displayed. |
