Abstract

Disclosed is a method and apparatus for scrolling data displayed on a screen, dividing a display region as a multiple of predefined weighted areas and setting a scroll velocity weight corresponding to each of the multiple of weighted areas when there is scrollable undisplayed data, after displaying data on the display region corresponding to execution of an application. Scroll velocity weight is detected corresponding to the initially produced point of the scroll input when a scroll input is sensed t, and an actual movement distance is detected corresponding to the scroll input in real-time until the scroll input ends. A scroll movement distance is calculating in proportion to the detected scroll velocity weight and the actual movement distance, and the data is displayed by shifting the data in a proceeding direction of the scroll input by the calculated scroll movement distance.

Claims

1. A data scroll method of a terminal, the terminal having a screen that displays data and an input means capable of a scroll input of data displayed on the screen, the method comprising the steps of

dividing a display region as a multiple of predefined weighted areas and setting a scroll velocity weight corresponding to each multiple of weighted areas when there is scrollable undisplayed data, after data is displayed on the display region corresponding to execution of an application;

detecting a scroll velocity weight corresponding to an initially produced point of the scroll input when a scroll input is sensed through the input means; and

detecting an actual movement distance corresponding to the scroll input in real-time until the scroll input ends, calculating a scroll movement distance in proportion to the detected scroll velocity weight and the actual movement distance and displaying the data by shifting the data in a proceeding direction of the scroll input by the calculated scroll movement distance.

2. The method of claim 1, wherein the detected scroll velocity weight is used for the scroll movement distance calculation until the scroll input ends.

3. The method of claim 2, wherein position and size of the multiple of weighted areas in the display region is determined according to a type of the application.

4. The method of claim 2, wherein position and size of the multiple of weighted areas in the display region is determined according to a form of the display region.

5. The method of claim 2, wherein position and size of the multiple of weighted areas in the display region is determined according to a scroll capable direction in the initial screen.

6. The method of claim 2, wherein the position and size of the multiple of weighted areas in the display region and a scroll velocity weight corresponding to each of the multiple of weighted areas are determined according to a user'"'"'s input.

7. The method of claim 1, wherein the input means is a touch panel installed on an upper part of the screen to construct a touch screen.

8. The method of claim 7, wherein when a scroll input by a finger panning is produced on the touch panel, the method further comprising:

determining the actual movement distance by the finger panning and a scroll input proceeding direction in real-time, calculating a scroll moving distance in proportion to the actual movement distance and displaying the data by shifting the data in the proceeding direction by the calculated scroll moving distance.

9. A data scroll apparatus comprising:

a screen for displaying data;

an input device capable of a scroll input of data displayed on the screen; and

a control unit for, after displaying data on a display region corresponding to execution of an application, dividing the display region as a multiple of predefined weighted areas and setting a scroll velocity weight corresponding to each of a multiple of the weighted areas when there is scrollable undisplayed data, detecting a scroll velocity weight corresponding to an initially produced point of the scroll input when a scroll input is sensed through the input device, and detecting an actual movement distance corresponding to the scroll input in real-time until the scroll input ends, calculating a scroll movement distance in proportion to the detected scroll velocity weight and the actual movement distance and displaying the data by shifting the data in a proceeding direction of the scroll input by the calculated scroll movement distance.

10. The apparatus of claim 9, wherein the detected scroll velocity weight is used for the scroll movement distance calculation until the scroll input ends.

11. The apparatus of claim 10, wherein position and size of the multiple of weighted areas in the display region is determined according to a type of the any application.

12. The apparatus of claim 10, wherein position and size of the multiple of weighted areas in the display region is determined according to a form of the display region.

13. The apparatus of claim 10, wherein position and size of the multiple of weighted areas in the display region is determined according to a scroll capable direction in the initial screen.

14. The apparatus of claim 10, wherein position and size of the multiple of weighted areas in the display region and a scroll velocity weight corresponding to each of the multiple of weighted areas are determined according to a user'"'"'s input.

15. The apparatus of claim 9, wherein the input device is a touch panel installed on an upper part of the screen to construct a touch screen.

16. The apparatus of claim 15, wherein when a scroll input by a finger panning is produced on the touch panel, the control unit determines the actual movement distance by the finger panning and a scroll input proceeding direction in real-time, calculates a scroll moving distance in proportion to the actual movement distance and displays the data by shifting the data in the proceeding direction by the calculated scroll moving distance.

17. A data scroll apparatus comprising:

a touch screen; and

a control unit for controlling that a size of a first data range scrolled according to a scroll input across a first length of a first region on the touch-screen is greater than a size of a second data range scrolled according to a scroll input across a first length of a second range, and controlling that a size of a third data range scrolled according to a scroll input across a first length starting from the first region and ending at the second region is a same as the size of the first data range.

18. The apparatus of claim 17, wherein the control unit determines the actual movement distance by a finger panning in real-time and displays the data by scrolling the same data in the proceeding direction when a scroll input by the finger panning is produced on the touch panel.
