  • FIG. 4A is a flowchart illustrating a control method of an apparatus including a touch screen according to an embodiment of the present invention; and FIGS. 5A through 5C are diagrams illustrating a touch screen that includes a reversal region according to various exemplary embodiments of the present invention.
  • Referring to FIG. 4A and FIGS. 5A to 5C, each step in FIG. 4A will be described with reference to FIGS. 5A through 5C. A first application and a second application may be respectively displayed on a first window and a second window on the touch screen 350, in step 401. As shown in FIG. 5A, the controller 110 may respectively display the first application on a first window 501 and the second application on a second window 502. A step of executing the first and second applications may be performed before step 401.
  • The controller 110 may determine whether a display change event is detected from the first window in step 402. If no display change event is detected at step 402, then the controller 110 may determine whether a display change event is detected from the second window in step 405. Here, the display change event may correspond to inputting an external input, from the user, that rotates, reverses, or shifts a displayed screen according to an external interface input scheme.
  • According to an exemplary embodiment of FIG. 5A, the display change event may correspond to a drag gesture input from a title bar 503 of the second window 502 to a boundary between the second window 502 and a menu key collection stack 504. Here, the drag gesture may correspond to a gesture that touches a first point of a touch screen, and drags up to a second point by maintaining the contact with the touch screen. The drag gesture from the top to the bottom, as described in the foregoing, may be a motion similar to a motion that reverses the top and bottom of a screen, and may be a gesture corresponding to a user's intuition. The display change event may be referred to as a screen reverse gesture.
  • If the display change event from the first window is detected in step 402 or if the display change event from the second window is detected in step 405, then the controller 110 or the second controller 110 b may detect a display change event such as a drag gesture input, and may respectively analyze the detected display change event in steps 403 or 406. For example, the controller 110 may read a lookup table associated with a relationship between a display change event and a changed display screen, previously stored in the storage unit 175, and may analyze the display change event according to the read lookup table. In particular, when the display change event occurs, the controller 110 may process the display change event in a framework through a kernel and may control to change a display of a screen.
  • Next, in steps 404 and 407, the controller 110 may control to display a changed screen respectively based on the analyzed results of steps 403 and 406. In other words, the controller 110 may analyze the display change event in step 403 and may then, in step 404, control to rotate a display direction of the first window based on the analyzed result of step 403. Also, the controller 110 may analyze the display change event in step 406 and may then, in step 407, control to rotate a display direction of the first window based on the analyzed result of step 406.
  • Referring to FIG. 5B, a display direction of a second application displayed in the second window 502 is displayed by being reversed in the up and down directions, that is, being rotated by 180 degrees. The second title bar 503 is also reversed and is disposed on the bottom of the second application execution screen 502. Here, the display direction may correspond to a direction in which an application execution screen displayed on the touch screen is displayed.
  • Based on the configuration as described in the foregoing, inconvenience due to the overlapping of workspaces in a case where two users respectively use a first application and a second application, may be overcome. For example, when the first and second applications are respectively displayed in the first and second windows 501 and 502 in the same direction, as illustrated in FIG. 5A, two users may need to manipulate the touch screen in the state where the two users are close to each other and thus, there is inconvenience caused by physical space restraint. However, when the first application and the second application are displayed in different directions, i.e., in different orientations, as illustrated in FIG. 5B, then the two users may be able to manipulate the touch screen in the state where the two users face each other and thus, the space restraint may be overcome. Accordingly, a plurality of users may control a plurality of different applications, respectively, using an apparatus including a single touch screen.
  • Referring to FIG. 5C, the display change event may correspond to a drag gesture from the bottom of the second window 502 at a location of the menu key selection stack 504 to the top of the second window 502. The drag gesture from the bottom to the top may be a motion similar to a motion that reverses the bottom and the top of a screen, and may correspond to a user's intuition.
  • The controller 110 may detect a drag gesture input from the bottom of the second window 502 to the top, and may analyze the detected drag gesture input. The controller 110 may analyze the drag gesture input, and may control to reverse the reversed second window 502 and the menu key selection stack 504 again so as to display the second window 502 and the menu key selection stack 504 as illustrated in FIG. 5A.
  • Although the apparatus control method of FIG. 4A is associated with the case in which a single display change event is independently input to the first window or the second window, the present invention is not limited thereto. When display change events are simultaneously and respectively input to the first window and the second window, the apparatus may change screens according to the display change events and display the changed screens.
  • FIG. 4B is a flowchart illustrating an apparatus control method according to another exemplary embodiment of the present invention.
  • A touch screen 195 may display a first application in a first window and a second application in a second window in step 411. Next, the controller 110 may determine whether a display change event is detected in step 412. When the display change event is not detected in step 412, then the first and second applications are respectively and continuously displayed on the first and second windows. If the display change even is detected in step 412, then the controller 110 may detect whether display change events are simultaneously detected from the first and second windows in step 413. When the display change events are simultaneously detected from the first and second windows in step 413, then the apparatus may simultaneously change the first and second windows and may display the changes in step 414. When a display change event is detected from only one of the first and second windows in step 413, then the apparatus may change a window where the display change event is detected and may display the change in step 415.
