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 displayed on a display of a hand-held apparatus, comprising:

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

gradually decreasing a scrolling speed of the screen to zero, if the hand-held apparatus is tilted at a first amount from the initial tilt that is less than or equal to a reference value; and

maintaining the scrolling speed of the screen, if the hand-held apparatus is tilted at a second amount from the initial tilt that is greater than the reference value.

2. The method of claim 1, further comprising, after continuing to scroll the screen at the scrolling speed when the hand-held apparatus is tilted 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:

based on the tilt of the hand-held apparatus returning 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 are re-set relative to the tilt of the hand-held apparatus.

7. The method of claim 1, further comprising, based on an additional touch input, 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 displayed on a display of a hand-held apparatus, comprising:

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

gradually decreasing a scrolling speed of the screen, if the hand-held apparatus is tilted a first amount from the initial tilt that is less than or equal to a reference value; and

changing the scrolling speed of the screen by an amount that is proportional to a second amount of tilt from the initial tilt, if the second amount of tilt from the initial tilt is greater than the reference value.

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

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

gradually decreasing a scrolling speed of the screen to zero, if the hand-held apparatus is tilted a first amount from the initial tilt that is less than or equal to a reference value; and

maintaining the scrolling speed of the screen, if the hand-held apparatus is tilted a second amount from the initial tilt that is greater than the reference value.

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

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

gradually decreasing a scrolling speed of the screen, if the hand-held apparatus is tilted a first amount from the initial tilt that is less than or equal to a reference value; and

changing the scrolling speed of the screen by an amount that is proportional to a second amount of tilt from the initial tilt, if the second amount of tilt from the initial tilt is greater than the reference value.

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

a display capable of receiving a touch input;

a motion sensor; and

a controller which;

based on a flicking input being detected on the display, controls the display to start scrolling a screen at an initial scrolling speed corresponding to a speed of the flicking input, wherein a tilt of the hand-held apparatus at a point of time of the flicking input corresponds to an initial tilt;

gradually decreases a scrolling speed of the screen to zero, if the motion sensor indicates that the hand-held apparatus is tilted a first amount from the initial tilt that is less than or equal to a reference value; and

maintains the scrolling speed of the screen, if the motion sensor indicates that the hand-held apparatus is tilted a second amount from the initial tilt that is greater than a reference value.

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

a display capable of receiving a touch input;

a motion sensor; and

a controller which;

based on a flicking input being detected on the display, starts scrolling the screen at an initial scrolling speed corresponding to a speed of the flicking input, wherein a tilt of the hand-held apparatus at a point of time of the flicking input corresponds to an initial tilt;

gradually decreases a scrolling speed of the screen, if the hand-held apparatus is tilted a first amount from the initial tilt that is less than or equal to a reference value; and

changes the scrolling speed of the screen by an amount that is proportional to a second amount of tilt from the initial tilt, if the second amount of tilt from the initial tilt is greater than the reference value.
