Abstract: A flexible display apparatus is provided. The flexible display apparatus includes a display, a sensor which senses shape deformation of the display, a storage which, if a shape deformation is sensed, stores operation state information of a first operation state of the flexible display apparatus prior to the first shape deformation being performed, and a controller which performs a function corresponding to the first shape deformation if a second shape deformation different from the first shape deformation is sensed, returns to the first operation state according to the operation state information stored in the storage.

Abstract: A method of providing feedback in a portable terminal by displaying a three dimensional screen, determining whether a user input in the three dimensional screen is detected; extracting a disparity of a specific content or a specific content output area layer corresponding to the detected user input, determining at least one of an intensity of feedback and a pattern of feedback corresponding to the extracted disparity, and providing feedback according to the at least one of the determined intensity of feedback and pattern of feedback.

Abstract: A mobile apparatus is provided including a display unit which displays layers in different depth degrees from each other and displays a plurality of layers which are arranged in a depth direction of a screen in 3D images, including a sensing unit to sense movement of the mobile apparatus, and a control unit which controls a plurality of layers according to movement direction and movement distance, when movement of the mobile apparatus moving toward a depth direction of a screen is sensed.

Abstract: An operating method of a three dimensional (3D) display terminal apparatus includes displaying a plurality of objects with different degrees of perceived depths, and changing display state of the plurality of objects according to a user's manipulation. The user's manipulation includes a plurality of touch modes which are perceived as different depths corresponding to the degrees of perceived depths, and the plurality of touch modes include a direct touch mode and a near touch mode. As a result, the terminal apparatus is operated with increased ease.

Abstract: A method and a 3D display apparatus for displaying a content list by setting a depth value of each content to be displayed on the content list according to content information, according to the plurality of content, and displaying 3D content list GUI including a left-eye GUI and a right-eye GUI to which a set depth value for each of the content is applied. Accordingly, the 3D display apparatus can display the content list using the stereo 3D GUI.
