Abstract

A menu displaying method for displaying a menu containing a plurality of menu items on a display screen comprises a menu item arrangement step of arranging the menu items in a prescribed three-dimensional virtual body to squarely face the display screen so that each menu item will have at least a viewable part that is not screened by other menu items in front of the menu item and a menu item moving step of moving the menu items arranged in the menu item arrangement step according to a prescribed user operation while keeping the menu items squarely facing the display screen. By the menu displaying method, a large number of menu items can be displayed on a screen while minimizing deterioration of viewability of the menu items.

Claims

1. A menu displaying device which displays a menu containing a plurality of menu items on a display screen, comprising:

a display unit capable of displaying the menu on the display screen as a three-dimensional menu;

a menu item arrangement unit, which is capable of executing the steps of;

defining a plurality of layers which are included in a prescribed three-dimensional virtual body; and

arranging the plurality of menu items on the plurality of layers so that each of said layers has at least two menu items, the plurality of menu items being arranged such that each menu item on one of the plurality of layers is not completely covered with each menu item on the other of the plurality of layers, thereby each menu item having at least a viewable part that is not screened by other menu items in front of the menu item; and

an icon displaying unit which displays an icon, having a same shape as the three-dimensional virtual body, as an input key to be operated by a user for specifying the movement of the menu items, on the display screen;

an icon moving unit which rotates the icon displayed on the display screen according to the operation by the user to the icon; and

a menu item moving unit which moves, in sync with the rotation of the icon, the plurality of menu items in the three-dimensional virtual body on a circular orbit around a prescribed axis in the three-dimensional virtual body in the same direction as the rotation of the icon at a predetermined angular speed, and rotates each menu item around its own axis in a direction opposite to the direction of the menu items on the circular orbit at the predetermined angular, speed, resulting in each of the plurality of menu items in the three-dimensional virtual body revolving on the circular orbit around the prescribed axis in the three-dimensional virtual body while remaining squarely facing the display screen of the display unit during the revolution.

2. The menu displaying device according to claim 1, including a menu item moving unit which moves each menu item along a prescribed virtual surface of the three-dimensional virtual body.

3. The menu displaying device according to claim 1, including a menu item moving unit which discretely moves each menu item to a position of an adjacent menu item substantially along a virtual surface of the three-dimensional virtual body.

4. The menu displaying device according to claim 1, further comprising a menu item selectability setting unit which sets each menu item in a selectable state or a non-selectable state depending on the size of the menu item displayed on the display screen.

5. The menu displaying device according to claim 4, wherein the menu item selectability setting unit sets each menu item in the selectable state or the non-selectable state depending on whether or not the menu item has a prescribed size enough for letting a user select the menu item.

6. The menu displaying device according to claim 1, wherein the menu items are replaceably arranged on a menu item by menu item basis.

7. The menu displaying device according to claim 1, wherein the menu items are of substantially the same size.

8. The menu displaying device according to claim 1, wherein said plurality of menu items displayed on each of the plurality of layers appear to extend (1) equidistantly along a first axis parallel to the front side of the display screen, (2) equidistantly along a second axis parallel to the front side of the display screen and perpendicular to the first axis and (3) equidistantly along said orthogonal axis, which is orthogonal to the front side of the display screen.
