Abstract

An apparatus and method for turning pages of an electronic-book (e-book) in a portable terminal having an e-book function. The method includes executing the e-book function, displaying a right lateral side of the e-book and receiving a inclination value from a 3-axis sensor when a touch event is detected in a right User Interface (UI) active area of the e-book, determining whether the inclination value greater than or equal to a threshold is detected in a left direction, and upon detection of the inclination value greater than or equal to the threshold in the left direction, displaying a next page to a screen on a single-page basis at a speed in proportion to the inclination value detected in the process of detecting the inclination greater than or equal to the threshold in the left direction.

Claims

in response to determining that the start position is in the middle region of the screen;

determining whether the first direction of the first input is towards the first UI activation region or the second UI activation region;

in response to determining that the first direction of the first input is towards the first UI activation region, displaying a just previous page on the screen; and

in response to determining that the first direction of the first input is towards the second UI activation region, displaying a just next page on the screen;

in response to determining that the start position of the first input is in the first UI activation region;

displaying a right side of the e-book;

determining whether the first direction of the first input is towards the right side of the screen; and

in response to determining that the first direction is towards the right side of the screen;

displaying a number of pages to be increased relative to the displayed at least one page;

receiving a first inclination value;

determining whether the first inclination value is greater than or equal to a threshold directed in a left direction; and

in response to determining that the first inclination value is greater than or equal to the threshold directed in the left direction, displaying a page corresponding to the number of pages to be increased; and

in response to determining that the start position of the first input is in the second UI activation region;

displaying a left side of the e-book;

determining whether the first direction of the first input is towards the left side of the screen; and

in response to determining that the first direction is towards the left side of the screen;

displaying a number of pages to be decreased relative to the displayed at least one page;

receiving a second inclination value;

determining whether the second inclination value is greater than or equal to a threshold directed in a right direction; and

in response to determining that the first inclination value is greater than or equal to the threshold directed in the right direction, displaying a page corresponding to the number of pages to be decreased.

2. The method of claim 1, wherein receiving the first inclination value comprises identifying the first inclination value when the first input is received.

3. The method of claim 1, further comprising when displaying the left side of the e-book where pages are being turned and in response to detecting a second direction of the first input that is towards the right side of the screen and subsequent release of the first input, canceling the displaying of the page corresponding to the number of pages to be increased.

4. The method of claim 1, wherein displaying the page corresponding to the number of pages to be decreased comprises displaying a previous page on a single-page basis on the screen at a speed in proportion to the second inclination value.

5. The method of claim 1, wherein receiving the second inclination value comprises identifying the inclination value when the first input is received.

6. The method of claim 1, further comprising:

when displaying the right side of the e-book where pages are being turned and in response to detecting a second direction of the first input that is towards the left side of the screen and subsequent release of the first input canceling the displaying of the page corresponding to the number of pages to be decreased.

7. The method of claim 1, wherein displaying the page corresponding to the number of pages to be increased comprises displaying a next page on a single-page basis on the screen at a speed in proportion to the first inclination value.

8. An apparatus for turning pages of an electronic book (e-book) in a portable terminal, the apparatus comprising:

a controller comprising hardware, the controller configured to;

define a first partial region of a screen on a first side as a first user interface (UI) activation region, a second partial region of the screen on an opposing side as a second UI activation region, and a middle region of the screen between the first partial region and the second partial region, the portable terminal comprising the screen, the screen comprising a touchscreen;
