15 . A method of executing an application in a touch device, the method comprising:

executing a first application corresponding to user selection and displaying the application through one window as a full screen;

receiving a first event input for selecting and moving a second application when the first application is executed;

determining a multi-window split scheme and a region to which the first event is input;

outputting a feedback for a window in which the second application is able to be executed and the region to which the first event is input;

receiving a second event input of executing the second application;

configuring the multi-window in response to the second event input; and

independently displaying a screen of the first application and a screen of the second application respectively through corresponding windows separated by the multi-window.

16 . The method of claim 15 , wherein the first event comprises an event for selecting an execution icon of the second application to be additionally executed from a tray and moving the selected execution icon into a screen.

17 . The method of claim 15 , wherein the second event comprises moving the execution icon and releasing the execution icon from a current window when the first event is not released.

18 . A method of executing an application in a touch device, the method comprising:

displaying an execution screen of a first application as a full screen;

sliding-in a tray including an execution icon of an application according to a user input when the first application is executed;

receiving an input for selecting an execution icon of a second application from the tray and dragging the selected execution icon into the full screen;

receiving an input for dropping the execution icon in a specific window while the execution icon is dragged;

executing the second application in response to the drop input of the execution icon;

splitting a full screen into windows for displaying screens of the first application and the second application; and

displaying a screen of the second application through the specific window in which the execution icon is dropped, and displaying the screen of the first application through another split window.

19 . The method of claim 18 , further comprising sliding-out the tray when the execution icon is selected and is moved to the full screen.

20 . The method of claim 18 , further comprising:

blanking a region to which the execution icon is allocated in the tray when the execution icon is selected and is moved to the full screen; and

restoring again the blanked region when the tray is slid-out.

21 . The method of claim 18 , further comprising outputting a feedback for the specific window into which the execution icon is dragged while the execution icon is moved on the full screen according to the drag.

22 . The method of claim 18 , further comprising:

popping-up a floating key pad when a text input is requested from an application of a specific window from among the split windows; and

inputting a text for the application of the specific window according to a user input using the floating key pad.

23 . The method of claim 22 , further comprising moving the floating key pad to another region in a screen to input a text for an application of another window.

24 . The method of claim 18 , wherein the windows for displaying the screens of the first application and the second application are split through a separator.

25 . The method of claim 24 , further comprising changing sizes of the windows according to a movement of the separator.

26 . A touch device comprising:

a touch screen configured to display a screen interface of a multi-window environment, to display screens of a plurality of applications through a plurality of windows separated in the screen interface, and to receive an event input for operating the plurality of applications; and

a controller configured to control execution of the plurality of applications in the multi-window environment, and to control to independently display screens of at least two applications according to a user selection from among a plurality of executed applications through the plurality of windows.

27 . The touch device of claim 26 , wherein the controller receives an input of an execution event for executing a second application when an execution screen of a first application is displayed as a full screen, configures a multi-window according to a split scheme when the execution event is released from a specific window, and controls to independently display screens of the first application and the second application through respective split windows.

28 . The touch device of claim 27 , wherein the controller controls a feedback output for a window of a moved location while an execution icon is moved in a state in which the execution event is not released.

29 . The touch device of claim 27 , wherein, when execution of an additional application is received while displaying screens of the plurality of applications through the multi-window, the controller executes the additional application through a selected window for executing the additional application, processes an application previously executed through the selected window as a background, and controls to display a screen of the additional application through the selected window.

30 . The touch device of claim 26 , wherein the screen interface comprises an execution icon of an application and a tray moved to another region in a screen according to a user input.
