1. An electronic-book display device for successively displaying a plurality of pages of an electronic book by one or more pages each time on a display screen, and turning the pages on the display screen in response to a user's input via finger touch of the display screen, the electronic-book display device comprising:
a touch-position recognizing unit configured to determine whether a touch position at which a touch event is performed with the finger on the display screen has an overlap with one of predetermined at least one region on the display screen; a page-turn-direction determining unit configured to be activated in response to an event occurring in which the touch position is determined to have an overlap with the predetermined at least one region, to determine a page turn direction in which the pages are to be turned on the display screen, based on information on a page turn direction assigned to the predetermined at least one region; a pressing-force sensor detecting a pressing force with which the finger or the user's another finger presses the display screen; a pressing-force recognizing unit configured to determine whether or not the detected pressing force is equal to or larger than a predetermined threshold; and an operation controller configured to be activated in response to an event occurring in which the detected pressing force is determined to be equal to or larger than the predetermined threshold, to authorize initiation of a page turn event for turning the pages on the display screen in the determined page-turn-direction.
