20140173495 | Bookmark Gesture Recognition - Apparatus for displaying an electronic book comprising a touch screen and a processor. The touch screen displays a selected page of an electronic book, and has a touch input device configured to generate signals in response to a touch input. The processor comprises a touch acquisition module that generates touch position information, a gesture recognition module that determines if a touch input is a bookmark gesture in dependence of whether the touch position information is within a bookmark area, and a bookmark processing module that generates a bookmark for the selected page when a bookmark gesture is recognized by the gesture recognition module. | 06-19-2014 |
