Abstract: An apparatus and method support intuitive gestures for turning electronic book (e-book) pages in a portable terminal. The portable terminal executes an e-book and determines whether a just preceding page gesture is input, the just preceding page gesture comprising a first contact that starts to the left of a right-side user interface (UI) activation region of the e-book, followed by a drag toward the right while maintaining the first contact and releasing the first contact. When the just preceding page gesture is input, the just preceding page is displayed on a screen.

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.

Abstract: An apparatus and method turn electronic book (e-book) pages in a portable terminal. The method determines whether a touch is input outside of a predetermined User Interface (UI) activation region of a screen of the portable terminal. The method determines whether a drag and release is input in a direction towards the predetermined UI activation region in response to detecting the touch. The method displays one of a preceding page and a next page on the screen in response to determining that the touch is outside of the predetermined UI activation region and that the drag and release is input in the direction towards the predetermined UI activation region.

Abstract: An apparatus and method turning pages of an electronic-book (e-book) in a portable terminal including an e-book function. The method includes displaying a first side of the e-book when a first touch is input in a first User Interface (UI) active area of a display of the portable terminal, displaying one of an immediately next page and a next page corresponding to an increased page number in response to a second touch being input in a second UI active area of the display and in response to a drag and release of the second touch while the first touch is maintained in the first UI active area, and cancelling the displaying of the one of the immediately next page and the next page corresponding to the increased page number in response to a drag and release of the first touch being input towards the second UI active area.
