Abstract

A method for displaying page shape includes displaying a page screen, detecting at least one touch starting point by a first user-manipulation on the page screen, detecting at least one dragging direction by a second user-manipulation made consecutively to the first user-manipulation, and dimensionally deforming the page screen based on the touch starting point and the dragging direction and displaying the deformed page screen.

Claims

1. A method for displaying a page shape, the method comprising the steps of:

displaying a page screen;

detecting a first touch starting point by a first user-manipulation on the page screen;

detecting a first dragging direction by a second user-manipulation made consecutively to the first user-manipulation;

dimensionally deforming the page screen based on the first touch starting point and the first dragging direction; and

displaying a deformed page screen, resulting from dimensionally deforming the page screen.

2. The method of claim 1, wherein displaying the deformed page screen comprises:

displaying the page screen where an upper side of the page screen is convexed according to the first dragging direction, if the first touch starting point is detected on a first area of the page screen; and

displaying the page screen where the upper side of the page screen is concaved according to the first dragging direction, if the first touch starting point is detected on a second area.

3. The method of claim 2, further comprising:

if the first touch starting point is positioned on a center of any one of the first and second areas on the page screen, displaying the page screen in a shape that a cross section of the page screen has a predetermined curvature of radius.

4. The method of claim 2, further comprising:

if the first touch starting point is positioned on an area other than a center of any one of the first and second areas on the page screen, displaying the page screen in a shape that a cross section of the page screen has a curvature of radius increasing from the first touch starting point of the page to the center.

5. The method of claim 2, further comprising:

if the second user-manipulation is discontinued, restoring the page screen to the first page screen in the form before the deformation, or displaying so that the page screen turns over to another page screen according to the position of discontinuing the second user-manipulation.

6. The method of claim 1, further comprising detecting a second touch starting point on the page screen, wherein dimensionally deforming the page screen and displaying the deformed page screen comprises dimensionally deforming the page screen corresponding to an area including the first touch starting point among the areas divided based on the first touch starting point, according to the first dragging direction made consecutively to the first touch, and the second touch starting point, and displaying the deformed page screen.

7. The method of claim 6, wherein, if the first user-manipulation of the first touch starting point is discontinued, restoring the page screen to a form before the deformation, or displaying the page screen in a form of being turned over to another page screen according to the position of discontinuing the first user-manipulation.

8. The method of claim 1, further comprising detecting a second touch starting point on the pages screen, wherein dimensionally deforming the page screen and displaying the deformed page screen comprises dimensionally deforming the page screen corresponding to an area between the first touch starting point and the second touch starting point toward the first dragging direction made consecutively to the first touch and a second dragging direction made consecutively to the second touch starting point and displaying the deformed page screen.

9. The method of claim 8, wherein the first and second dragging directions are orthogonal to the page screen and approaching toward each other.

19. The method of claim 1, wherein the page shape is displayed in an electronic book.

10. A display apparatus, comprising:

a display configured to display a page screen;

a detector configured to detect a first touch starting point by a first user-manipulation on the page screen and a first dragging direction by a second user-manipulation consecutively made to the first user-manipulation; and

a controller configured to dimensionally deform the page screen based on the first touch starting point and the first dragging direction and display the deformed page screen, resulting from dimensionally deforming the page screen.

11. The display apparatus of claim 10, wherein the controller displays the page screen where an upper side of the page screen is convexed in the first dragging direction, if the first touch starting point is detected on a first area of the page screen, and displays the page screen where the upper side of the page screen is concaved in the dragging direction, if the first touch starting point is detected on a second area of the page screen.

12. The display apparatus of claim 11, wherein, if the first touch starting point is positioned on a center of any one of the first and second areas on the page screen, the controller displays the page screen in a shape that a cross section of the page screen has a predetermined curvature of radius.

13. The display apparatus of claim 11, wherein, if the first touch starting point is positioned on an area other than a center of any one of the first and second areas on the page screen, the controller displays the page screen in a shape that a cross section of the page screen has a curvature of radius increasing from the top to the bottom of the page screen.

14. The display apparatus of claim 11, wherein, if the second user-manipulation is discontinued, the controller restores the page screen to a form before the deformation, or displays the page screen in a form of being turned over to another page screen according to the position of discontinuing the second user-manipulation.

15. The display apparatus of claim 10, wherein the detector detects a second touch starting point, and wherein the controller dimensionally deforms the page screen corresponding to an area including the first touch starting point among the areas divided based on the first touch starting point, according to the first dragging direction from the first touch starting point, and the second touch starting point.

16. The display apparatus of claim 15, wherein, if the first user-manipulation of the first touch starting point is discontinued, the controller restores the page screen to a form before the deformation, or displays the page screen in a form of being turned over to another page screen according to the position of discontinuing the first user-manipulation.

17. The display apparatus of claim 15, wherein the detector detects a second touch starting point, and wherein the controller dimensionally deforms the page screen corresponding to an area between the first touch starting point and the second touch starting point toward the first dragging direction made consecutively to the first touch starting point and the second dragging direction made consecutively to the second touch starting point and displays the deformed page screen.

18. The display apparatus of claim 17, wherein the first and second dragging directions are orthogonal to the page screen and approaching toward each other.
