Referring to FIG. 15, a user executes a gallery application in the flexible device 100. In this regard, it is assumed that the user performs a folding-flap input to the flexible device 100 on the gallery application. The flexible device 100 may display a screen by changing a display mode to a split mode according to the folding-flap input.
If the user performs the folding-flap input to the flexible device 100, a user interface 1520 may be generated. In this regard, it is assumed that the user interface 1520 may be a toolset bar. If the user taps one of items of the toolset bar by using a user's finger, a corresponding function may be performed. For example, if the user may tap a pencil icon 1525 by using the user's finger, a popup 1530 for selecting a color of a pencil that is to be colored may be executed. In this regard, the user may continuously tap the pencil icon 1525 twice by using the user's finger, and the popup 1530 for selecting the color of the pencil that is to be colored may expand, and thus the expanded popup 1530 may be displayed on a lower screen 1540 of a screen boundary 1510.
FIG. 16 is a diagram for describing a process in which a user uses a user interface in an executed gallery application according to another embodiment.
Referring to FIG. 16, a user performs a folding-flap input to the flexible device 100. The flexible device 100 may receive the folding-flap input and display a user interface 1620. In this regard, the displayed user interface 1620 may be a toolset bar. In this regard, if the user moves a user's finger from the left of a left boundary of the user interface 1620 to the right, the user interface 1620 may be switched. In this regard, the displayed user interface 1620 may be an application history bar. Among icons included in the application history bar, if the user moves the user's finger from an icon indicative of the Internet below a boundary 1610, the Internet may be executed below the boundary 1610. In this regard, a gallery preview screen that was originally displayed on the lower end of the boundary 1610 may be moved to an upper end of the boundary 1610 and displayed. Thereafter, if the user performs the folding-flap input to the flexible device 100, the user interface 1620 may disappear.
FIG. 17 is a diagram for describing a process in which a user checks a real-time notification according to an embodiment.
If a notification event occurs, a notification icon 1710 may be displayed on the flexible device 100. In this regard, if a user performs a folding-hold input to the flexible device 100, a message 1720 simply indicative of notification event content may be displayed on a screen. However, the present embodiment is not limited thereto. If the user performs the folding-hold input to the flexible device 100, the flexible device 100 may automatically execute an application in which the notification event occurs so that the user may check detailed content of a message corresponding to a notification.
After the user checks the notification event content, if the user performs a folding-hold release input to the flexible device 100, the message 1720 indicative of the notification event content may disappear from the screen. However, the present embodiment is not limited thereto. If the user performs the folding-hold release input to the flexible device 100, the flexible device 100 may end the application in which the notification event occurs and return to a previously used application.
FIG. 18 is a diagram for describing a process of displaying a user interface on a specific portion when a user folds a flexible device according to another embodiment.
When a user performs a folding-flap input to the flexible device 100, the user may asymmetrically fold the flexible device 100. When the flexible device 100 is asymmetrically folded, a portion 1810 may not be covered. When the user releases the flexible device 100 again, a user interface 1820 may be displayed on the portion 1810 that is not covered.
The embodiments described above can be written as computer programs and can be implemented in general-use digital computers that execute the programs using a computer-readable recording medium.
Examples of the computer-readable recording medium include magnetic storage media (e.g., ROM, floppy disks, hard disks, etc.), optical recording media (e.g., CD-ROMs, or DVDs), etc.
While one or more embodiments have been described with reference to the figures, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope as defined by the following claims. Therefore, it should be understood that embodiments described herein should be considered in a descriptive sense only and not for purposes of limitation.
