Abstract

In one example embodiment, an interface providing method in an interface providing system implemented with a computer including a touch screen, includes displaying, by a processor, contents on the touch screen, and activating and displaying, by the processor, a pointer object at a position corresponding to a position of a touch on the touch screen. The method further includes moving, by the processor, the pointer object as a position of the touch moves in a state where the touch is maintained, controlling, by the processor, a rotation of contents displayed on the touch screen based on the moving of the pointer object, and deactivating, by the processor, the pointer object and the displaying of the pointer object, when the touch is terminated.

Claims

1. An interface providing method in an interface providing system implemented with a computer including a touch screen, the method comprising:

displaying, by a processor, contents on the touch screen;

activating and displaying, by the processor, a pointer object at a position corresponding to a position of a touch on the touch screen;

moving, by the processor, the pointer object as a position of the touch moves in a state where the touch is maintained;

controlling, by the processor, a rotation of contents displayed on the touch screen based on the moving of the pointer object; and

deactivating, by the processor, the pointer object and the displaying of the pointer object, when the touch is terminated.

2. The method of claim 1, wherein the activating and displaying the pointer object comprises:

further displaying a scroll bar object, for guiding a movement of the pointer object,

wherein the moving moves the pointer object along the scroll bar object.

3. The method of claim 1, wherein the controlling the rotation of the contents displayed on the touch screen comprises:

moving the pointer object according to a variance of a first direction of movement of the touch or a variance of an opposite direction of the first direction and rotating the contents relative to a Z axis of a 3-dimensional (3D) coordinate system; and

rotating the contents relative to an X axis of the 3D coordinate system according to a variance of a second direction of movement of the touch or a variance of an opposite direction of the second direction.

4. The method of claim 3, wherein

the moving the pointer object moves the pointer object along an axis corresponding to the first direction, and

an axis corresponding to the first direction is perpendicular to an axis corresponding to the second direction.

5. The method of claim 3, wherein the rotation of the contents according to the variance of the second direction is limited to an angle range of −

90 degrees to 90 degrees.

6. The method of claim 1, wherein the controlling the rotation of the contents displayed on the touch screen comprises:

calculating an angle of rotation relative to an axis of a 3-dimensional (3D) coordinate system according to a value in which a pixel variance of a direction of movement of the touch is changed to a density-independent pixels (DP) variance and a weight value.

7. The method of claim 1, wherein the controlling the rotation of the contents displayed on the touch screen comprises:

when a current first rotation angle of the contents is changed to a second rotation angle calculated according to a movement of the touch to display the contents, determining a rotation angle of the contents in a next frame using a third rotation angle calculated per frame according to an interpolation method to which the first rotation angle, the second rotation angle, and a smoothing factor are applied.

8. The method of claim 1, wherein the contents include a map screen provided by a map service.

9. A non-transitory computer-readable medium storing computer-readable instructions, which when executed by a processor, cause the processor to perform the method of claim 1.

10. An interface providing system implemented with a computer including a touch screen, the system comprising:

a processor configured to execute computer-readable instructions to,

display contents on the touch screen,

activate and display a pointer object at a position corresponding to a position of a touch on the touch screen,

move the pointer object as a position of the touch moves in a state where the touch is maintained

control a rotation of contents displayed on the touch screen based on the movement of the pointer object, and

deactivate the pointer object and the displaying of the pointer object, when the touch is terminated.

11. The system of claim 10, wherein the processor is configured to display a scroll bar object, for guiding a movement of the pointer object,

wherein the processor is configured to move the pointer object along the scroll bar object.

12. The system of claim 10, wherein the controller is configured to,

move the pointer object according to a variance of a first direction of movement of the touch or a variance of an opposite direction of the first direction and rotates the contents relative to a Z axis of a 3-dimensional (3D) coordinate system;

and

rotate the contents relative to an X axis of the 3D coordinate system according to a variance of a second direction of movement of the touch or a variance of an opposite direction of the second direction.

13. The system of claim 10, wherein the processor is configured to calculate an angle of rotation relative to an axis of a 3-dimensional (3D) coordinate system according to a value in which a pixel variance of a movement of the touch is changed to a density-independent pixels (DP) variance and a weight value.

14. The system of claim 10, wherein when a current first rotation angle of the contents is changed to a second rotation angle calculated according to a movement of the touch to display the contents, the processor is configured to determine a rotation angle of the contents in a next frame using a third rotation angle calculated per frame according to an interpolation method to which the first rotation angle, the second rotation angle, and a smoothing factor are applied.

15. The system of claim 10, wherein the contents include a map screen for a map service.
