         3 . The method of  claim 2 , further comprising matching the stored position of the first window with an input position of the first command and matching the position of the second window with an input position of the second command. 
     
     
         4 . The method of  claim 3 , further comprising dispatching the first command to the first application and dispatching the second command to the second application based on the matching outcome. 
     
     
         5 . The method of  claim 1 , wherein the first command and the second command are received simultaneously when a difference between a time when the first command is received and a time when the second command is received is smaller than a threshold. 
     
     
         6 . The method of  claim 1 , wherein ouputting the first command includes:
 dispatching the first command based on the first event when it is determined that the first command and the second command are received simultaneously; and   otherwise, dispatching the first command based on display rankings of the first command and the second command, when it is determined that the first command and the second command are not received simultaneously.   
     
     
         7 . A display device for executing an application, the display device comprising:

         8 . The display device of  claim 7 , wherein the controller is configured to determine positions of the first window and the second window, store the determined positions of the first window and the second window, and display the first window and the second window based on the determined positions of the first window and the second window. 
     
     
         9 . The display device of  claim 7 , wherein the controller matches the stored position of the first window with an input position of the first command and matches the position of the second window with an input position of the second command. 
     
     
         10 . The display device of  claim 9 , wherein the controller is further configured to:
 dispatch the first command to the first application only when the first application the position of the first window is determined to match the first command; and   dispatches the second command to the second application only when the position of the second window is determined to match the second command.   
     
     
         11 . The display device of  claim 7 , wherein the controller is further configured to determine whether the first command and the second command are input simultaneously, the determining being based on whether a difference between a time when the first command is input and a time when the second command is input is smaller than a threshold. 
     
     
         12 . The display device of  claim 7 , the first command is dispatched based on whether a position of the first window is determined to match the first command only when the first command and the second command are determined to have been received simultaneously. 
     
     
         13 . The display device of  claim 8 , wherein the controller is further configured to store in a memory a record indicating the positions of the first window and the second window. 
     
     
         14 . The display device of  claim 8 , wherein the controller is further configured to:
 match a position of the first window with an input position of the first command;   match a position of the second window with an input position of the second command;   dispatch the first command based on whether the position of the first window is determined to match the first command; and   dispatch the second command based on whether the position of the second window is determined to match the second command.   
     
     
         15 . A method for controlling a display device, the method comprising:
 displaying a plurality of windows, each window executing a different application;   receiving a plurality of commands that are input into the plurality of windows, each command being received at a different window, wherein the commands are received simultaneously; and   simultaneously inputting commands to two or more windows among the plurality of windows; and   processing the commands input to the windows on the input windows.   
     
     
         16 . The method of  claim 15 , wherein processing the commands includes outputting events corresponding to the commands to applications executed in the windows. 
     
     
         17 . The method of  claim 15 , wherein processing the commands includes, for each command, comparing an input location associated with that command with locations associated with each one of the plurality of windows. 
     
     
         18 . A display device for executing applications, the display device comprising:
