Abstract

A method of scrolling a screen in a display apparatus includes initiating a screen-scroll according to a speed of a currently generated flick input when the flick input is generated, comparing a tilt of an axis of a corresponding apparatus with an initial location at a time of generation of the flick input to determine whether a change amount of a change is within a reference value, maintaining a current screen-scroll speed if the change amount deviates from the reference value, and stopping a screen-scroll operation when a scroll stop condition is met.

Claims

1. A method of scrolling a screen on a display of a hand-held apparatus, comprising:

when a flicking input is detected on the screen, scrolling the screen starting at an initial speed corresponding to a speed of the flicking input, wherein a tilt of the hand-held apparatus at the time of the flicking input corresponds to an initial tilt; and

if the hand-held apparatus tilts from the initial tilt more than a reference value, maintaining a current scroll speed,

wherein, unless at least one of the hand-held apparatus tilts from the initial axis more than the reference value, the scrolling speed gradually decreases to zero.

2. The method of claim 1, further comprising, after continuing to scroll the screen at the current scroll speed when the hand-held apparatus tilts from the initial tilt more than the reference value:

varying the speed of the scrolling according to the tilt of the hand-held apparatus.

3. The method of claim 2, wherein varying the speed of the scrolling according to the tilt of the hand-held apparatus comprises:

if the tilt of the hand-held apparatus returns to be about identical to the initial tilt, stopping the scrolling of the screen.

4. The method of claim 2, wherein varying the speed of the scrolling according to the tilt of the hand-held apparatus comprises:

varying the speed of the scrolling according to a difference between the tilt of the hand-held apparatus and the initial tilt, wherein the speed of the scrolling is proportional to the difference.

5. The method of claim 2, wherein varying the speed of the scrolling according to the tilt of the hand-held apparatus comprises:

varying the speed of the scrolling according to which of a plurality of preset tilt ranges the tilt of the hand-held apparatus is in, wherein the preset tilt ranges are set relative to the initial tilt.

6. The method of claim 5, wherein the preset tilt ranges may be re-set relative to a current tilt of the hand-held apparatus.

7. The method of claim 1, further comprising, if a additional touch input is made, stopping the scrolling of the screen.

8. The method of claim 1, wherein the tilt of the hand-held apparatus is measured in an axis from a center of a top of the hand-held apparatus to the center of a bottom of the hand-held apparatus.

9. The method of claim 8, wherein the tilt from the initial tilt is measured in a plane perpendicular to the display of the hand-held apparatus.

10. The method of claim 8, wherein the tilt from the initial tilt is measured in a plane parallel to the display of the hand-held apparatus.

11. The method of claim 1, wherein the tilt of the hand-held apparatus is measured in an axis from a center of a side of the hand-held apparatus to the center of an opposite side of the hand-held apparatus and the tilt from the initial axis is measured in a plane perpendicular to the display of the hand-held apparatus.

12. A method of scrolling a screen on a display of a hand-held apparatus, comprising:

when a flicking input is detected on the screen, scrolling the screen starting at an initial speed corresponding to a speed of the flicking input, wherein a tilt of the hand-held apparatus at the time of the flicking input corresponds to an initial tilt;

if the hand-held apparatus does not tilt from the initial tilt more than the reference value, gradually decreasing the scrolling speed; and

if the hand-held apparatus tilts from the initial tilt more than a reference value, changing a current scrolling speed an amount proportional to the tilt of the hand-held apparatus from the initial tilt.

13. A non-transitory computer-readable recording medium having recorded thereon a computer program for executing a list view operation for scrolling a screen on a display of a hand-held apparatus, comprising:

when a flicking input is detected on the screen, scrolling the screen starting at an initial speed corresponding to a speed of the flicking, wherein a tilt of the hand-held apparatus at a time of the flicking input corresponds to an initial tilt; and

if the hand-held apparatus tilts from the initial tilt more than a reference value, maintaining a current scroll speed,

wherein, unless at least one of the hand-held apparatus tilts from the initial tilt more than the reference value, the scrolling speed gradually decreases to zero.

14. A non-transitory computer-readable recording medium having recorded thereon a computer program for executing a list view operation for scrolling a screen on a display of a hand-held apparatus, comprising:

when a flicking input is detected on the screen, scrolling the screen starting at an initial speed corresponding to a speed of the flicking input, wherein a tilt of the hand-held apparatus at a time of the flicking input corresponds to an initial tilt;

if the hand-held apparatus does not tilt from the initial tilt more than the reference value, gradually decreasing the scrolling speed; and

if the hand-held apparatus tilts from the initial tilt more than the reference value, changing a current scrolling speed an amount proportional to the tilt of the hand-held apparatus from the initial tilt.

15. A hand-held apparatus which executes a list view operation, comprising:

a display capable of touch input;

a motion sensor; and

a controller which;

when a flicking input is detected on a screen shown in the display, controls the display to scroll the screen starting at an initial speed corresponding to a speed of the flicking input, wherein a tilt of the hand-held apparatus at a time of the flicking input corresponds to an initial tilt; and

if the motion sensor indicates that the hand-held apparatus tilts from the initial tilt more than a reference value, controls the display to maintain a current scroll speed,

wherein, unless at least one of the hand-held apparatus tilts from the initial tilt more than the reference value, the scrolling speed gradually decreases to zero.

16. A hand-held apparatus which executes a list view operation, comprising:

a display capable of touch input;

a motion sensor; and

a controller which;

when a flicking input is detected on the screen, scrolling the screen starting at an initial speed corresponding to a speed of the flicking input, wherein a tilt of the hand-held apparatus at a time of the flicking input corresponds to an initial tilt;

if the hand-held apparatus does not tilt from the initial tilt more than a reference value, gradually decreasing the scrolling speed; and

if the hand-held apparatus tilts from the initial tilt more than the reference value, changing a current scrolling speed an amount proportional to the tilt of the hand-held apparatus from the initial tilt.
