Abstract

A method and system for displaying a screen in a mobile device are provided. The method includes displaying a list of items where the items are arranged in a three-dimensional form, viewed from a side, receiving a command for altering the display form of the list of items, and altering and displaying the image of the list of items, viewed from the side, into an image of the list of items viewed from above. The method and system allow a user to easily and rapidly search for a corresponding item on a screen of a mobile device.

Claims

1. A method for displaying a screen, the method comprising:

displaying a first view image of an ordered list of discrete items having items arranged in a three-dimensional form and sorted by a category of each item, the first view image comprising at least one item of the ordered list and a display form viewed from a first direction of the three-dimensional form;

displaying, when there is an input for altering the first view image of the ordered list, a second view image of the entire ordered list of the three-dimensional form and a display form of the entire ordered list viewed from a second direction of the three-dimensional form;

identifying at least an item corresponding to a selected region when a certain region is selected on the second view image; and

displaying information related to the identified item within the second view image,

wherein the first view image displays the at least one item as a currently focused item in the ordered list distinguished from other items in the ordered list,

wherein the second view image forms a circle and displays the entire ordered list as the three-dimensional form divided into discrete categories of the items grouped according to a category of each item, and does not display discrete items that are displayed together in the first view image other than the focused item, and

wherein the input for altering the display form is a touch and drag input that is performed in a direction perpendicular to the arrangement of the items or a key set input.

2. The method of claim 1, wherein displaying the second view image comprises displaying category information with the discrete categories.

3. The method of claim 1, wherein displaying the second view image comprises displaying information related to the currently focused item.

4. The method of claim 1, further comprising:

identifying, when there is an input on the second view image, an item corresponding to the input; and

displaying, when there is another input for altering the display form of the ordered list, the first view image comprising at least part of the items including the identified item.

5. The method of claim 4, further comprising displaying information related to the identified item.

6. The method of claim 4, wherein the another input for altering the display form is a touch and drag input in a direction opposite to a direction of the input for the display form or a key set input.

7. The method of claim 4, wherein displaying the first view image comprising at least part of the items including the identified item comprises displaying the identified item in a center of the at least part of the ordered list.

8. The method of claim 1, further comprising:

identifying, when there is an input on the second view image, a category corresponding to the input; and

displaying, when there is another input for altering the display form of the ordered list, the first view image comprising at least part of the items included in the identified category.

9. The method of claim 1, wherein the category is an index.

10. The method of claim 1, further comprising:

re-sorting, when there is an input for selecting type of the category, the items by the selected type of the category.

11. The method of claim 1, wherein displaying the second view image comprises:

determining a number of indexes (N) contained in the ordered list;

comparing the number of indexes (N) contained in the ordered list with a number of indexes (M) that can be displayed on one screen; and

displaying, when N is equal to or less than M, the N indexes in a preset order.

12. The method of claim 11, wherein displaying the second view image further comprises:

determining, when N is greater than M, a number of items classified by respective indexes;

determining an order of the indexes in an order from a largest number of items to a least; and

displaying the first to M^th indexes in the preset order.

13. The method of claim 12, wherein displaying the second view image further comprises:

grouping at least one index from among the (M+1)^th to N^th indexes into one from among the first to M^th indexes.

14. The method of claim 11, wherein the displaying of the N indexes comprises:

detecting a number of items classified by respective indexes;

determining sizes of regions corresponding to the respective indexes according to the detected number of items; and

allocating the determined sizes of regions to the N indexes, in the preset order, and displaying them.

15. The method of claim 14, further comprising:

detecting, when N is greater than M, the number of items classified by respective indexes;

determining an order of indexes in order from a largest number of items to a least;

determining sizes of regions corresponding to the first to M^th indexes, according to the detected number of items; and

allocating the determined sizes of regions to the first to M^th indexes, in the preset order, and displaying them.

16. The method of claim 15, wherein displaying the second view image further comprises:

grouping at least one index from among the (M+1)^th to N^th indexes into one from among the first to M^th indexes.

17. A system for displaying a screen, the system comprising:

a display unit;

an input unit configured to receive a command; and

a processor configured to;

control the display unit to display a first view image of an ordered list of discrete items having items arranged in a three-dimensional form and sorted by a category of each item, the first view image comprising at least one item of the ordered list and a display form viewed from a first direction of the three-dimensional form,

control the display unit to display, when there is an input for altering the first view image of the list of discrete items, a second view image of the entire ordered list of the three-dimensional form and a display form of the entire ordered list viewed from a second direction of the three-dimensional form,

identify at least an item corresponding to a selected region when a certain region is selected on the second view image, and

control the display unit to display information related to the identified item within the second view image,

wherein the first view image displays the at least one item as a currently focused item in the ordered list distinguished from other items in the ordered list,

wherein the second view image forms a circle and displays the entire ordered list as the three-dimensional form divided into discrete categories of the items grouped according to a category of each item, and does not display discrete items that are displayed together in the first view image other than the focused item, and

wherein the input for altering the display form is a touch and drag input that is performed in a direction perpendicular to the arrangement of the items or a key set input.
