HIERARCHICAL STRUCTURE DISPLAY DEVICE
First Claim
1. A hierarchical structure display device comprising:
- a hierarchical structure storing unit that stores information about a hierarchical structure of menus where each item contained in a menu is linked to a directly beneath level menu;
a display unit that has a display screen extending in a first direction and a second direction orthogonal to the first direction;
a designating unit that designates an item contained in each of the menus; and
a display control unit that controls the display unit to display at least one menu in the display screen based on the information stored in the hierarchical structure storing unit and to preserve at least a first region in the display screen for displaying titles of items contained in a menu of interest, wherein the titles of items contained in a menu are arranged one after another in the second direction with each title extending in the first direction, and the first region has a first length in the first direction long enough to entirely visibly indicate the titles of items, and wherein when the designating unit designates items in succession while advancing to a deeper level of the menus, the display control unit controls the display unit to preserve in the display screen not only the first region but also a second region that has a second length extending in the first direction and being shorter than the first length and to display at least a part of the menus in the second region.

Abstract
The hierarchical structure display device includes a hierarchical structure storing unit, a display unit, and a display control unit. The hierarchical structure storing unit stores information about a hierarchical structure of menus where each item contained in a menu is linked to a directly beneath level menu. The display control unit controls the display unit to display at least one menu in the display screen and to preserve at least a first region in the display screen for displaying titles of items contained in a menu of interest. The titles of items contained in a menu are arranged one after another in the second direction with each title extending in the first direction, and the first region has a first length in the first direction long enough to entirely visibly indicate the titles of items. When the designating unit designates items in succession while advancing to a deeper level of the menus, the display control unit controls the display unit to preserve in the display screen not only the first region but also a second region that has a second length extending in the first direction and being shorter than the first length and to display at least a part of the menus in the second region.

1. A hierarchical structure display device comprising:
-
a hierarchical structure storing unit that stores information about a hierarchical structure of menus where each item contained in a menu is linked to a directly beneath level menu; a display unit that has a display screen extending in a first direction and a second direction orthogonal to the first direction; a designating unit that designates an item contained in each of the menus; and a display control unit that controls the display unit to display at least one menu in the display screen based on the information stored in the hierarchical structure storing unit and to preserve at least a first region in the display screen for displaying titles of items contained in a menu of interest, wherein the titles of items contained in a menu are arranged one after another in the second direction with each title extending in the first direction, and the first region has a first length in the first direction long enough to entirely visibly indicate the titles of items, and wherein when the designating unit designates items in succession while advancing to a deeper level of the menus, the display control unit controls the display unit to preserve in the display screen not only the first region but also a second region that has a second length extending in the first direction and being shorter than the first length and to display at least a part of the menus in the second region. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A hierarchical structure display method that controls a hierarchical structure display device storing information about a hierarchical structure of menus where each item contained in a menu is linked to a directly beneath level menu, and having a display unit that has a display screen extending in a first direction and a second direction orthogonal to the first direction, the method comprising:
-
designating an item contained in each of the menus; and controlling the display unit to display at least one menu in the display screen based on the information about the hierarchical structure of menus and to preserve at least a first region in the display screen for displaying titles of items contained in a menu of interest, wherein the titles of items contained in a menu are arranged one after another in the second direction with each title extending in the first direction, and the first region has a first length in the first direction long enough to entirely visibly indicate the titles of items, and wherein when the designating designates items in succession while advancing to a deeper level of the menus, the controlling controls the display unit to preserve in the display screen not only the first region but also a second region that has a second length extending in the first direction and being shorter than the first length and to display at least a part of the menus in the second region.

17. A computer-readable storage medium storing a set of program instructions executable on a hierarchical structure display device that stores information about a hierarchical structure of menus where each item contained in a menu is linked to a directly beneath level menu, and that has a display unit having a display screen extending in a first direction and a second direction orthogonal to the first direction, the program instructions comprising:
-
designating an item contained in each of the menus; and controlling the display unit to display at least one menu in the display screen based on the information about the hierarchical structure of menus and to preserve at least a first region in the display screen for displaying titles of items contained in a menu of interest, wherein the titles of items contained in a menu are arranged one after another in the second direction with each title extending in the first direction, and the first region has a first length in the first direction long enough to entirely visibly indicate the titles of items, and wherein when the designating designates items in succession while advancing to a deeper level of the menus, the controlling controls the display unit to preserve in the display screen not only the first region but also a second region that has a second length extending in the first direction and being shorter than the first length and to display at least a part of the menus in the second region.
