A method of three-dimensionally rotating a plurality of menus displayed in an ordered stack on a display unit of a portable telephone. The method displays the plurality of menus three-dimensionally on the display unit according to the ordered stack. The menu displayed in front is a current menu and the remainder of the menus are displayed in order behind the current menu. A menu rotation direction is selected and the plurality of menus are rotated in the menu rotation direction in accordance with the ordered stack. In this manner, the next menu in the ordered stack is rotated in the menu rotation direction to the front and becomes the current menu.
1. A method of three-dimensionally rotating a plurality of menus displayed in an ordered stack on a display unit of a portable telephone, comprising the steps of:
displaying said plurality of menus three-dimensionally on said display unit according to said ordered stack by displaying a current menu in a front position and arranging a remainder of said plurality of menus behind said current menu by displaying portions of said remainder of said plurality of menus behind both sides of said current menu, wherein each of said plurality of menus is two-dimensional and single-sided;
selecting a menu rotation direction on said portable telephone; and
sequentially rotating said plurality of menus in said menu rotation direction in accordance with said ordered stack, wherein a next menu in said ordered stack is rotated to said front position and becomes said current menu.
2. The method according to claim 1 , wherein said current menu is enlarged and displayed at a high luminance level; and
wherein said remainder of said plurality of menus are displayed at incrementally decreasing luminance levels as a number of menus from said current menu increases in said ordered stack.
3. The method according to claim 1 , further comprising the steps of:
selecting a current item from a plurality of items displayed in said current menu; and
enlarging and displaying said current item at a high luminance level, wherein a remainder of said plurality of items are displayed at incrementally decreasing luminance levels as a number of items from said current item increases in said current menu.
4. The method according to claim 3 , further comprising a step of:
displaying a lower hierarchical menu corresponding to said current item, wherein said lower hierarchical menu is displayed in a same color as said current menu.
5. The method according to claim 1 , wherein each of said plurality of menus is assigned and displayed in a distinct color.
6. An information processing device for three-dimensionally rotating a plurality of menus displayed in an ordered stack on a display unit of a portable telephone, comprising:
display means for displaying said plurality of menus three-dimensionally on said display unit according to said ordered stack, wherein each of said plurality of menus is two-dimensional and single-sided;
arranging means for arranging a current menu in a front position and a remainder of said plurality of menus behind said current menu by displaying portions of said remainder of said plurality of menus behind both sides of said current menu;
selection means for selecting a menu rotation direction on said portable telephone; and
control means for sequentially rotating said plurality of menus in said menu rotation direction in accordance with said ordered stack, wherein a next menu in said ordered stack is rotated in said menu rotation direction to said front position and becomes said current menu.
7. The information processing device according to claim 6 , wherein said current menu is enlarged and displayed at a high luminance level; and
wherein said remainder of said plurality of menus are displayed at incrementally decreasing luminance levels as a number of menus from said current menu increases in said ordered stack.
8. The information processing device according to claim 6 , wherein said selection means selects a current item from a plurality of items displayed in said current menu;
wherein said display means enlarges and displays said current item at a high luminance level; and
wherein a remainder of said plurality of items are displayed at incrementally decreasing luminance levels as a number of items from said current item increases in said current menu.
9. The information processing device according to claim 8 , wherein said display means displays a lower hierarchical menu corresponding to said current item; and
wherein said lower hierarchical menu is displayed in a same color as said current menu.
10. The information processing device according to claim 6 , wherein each of said plurality of menus is assigned and displayed in a distinct color.
