Abstract: A display apparatus includes a display, an input module configured to receive a user input, and a processor configured to display a user interface (UI) to provide a plurality of objects to be selected on the display, receive the user input from the input module to select at least one of the plurality of objects from the UI displayed on the display, and change a size of the selected at least one object corresponding to the user input by enlarging the size of the selected at least one object corresponding to the user input during a first time and reduce the size of the selected at least one object corresponding to the user input during a second time, or by reducing the size of the selected at least one object corresponding to the user input during the first time and enlarge the size of the selected at least one object corresponding to the user input during the second time.

Abstract: A method and apparatus for providing a multi-screen environment as a more effective user interface are disclosed. The apparatus may include a user interface, a display, and a processor. While first content is being displayed on the display, when a user input representing a request to start second content is received through a user interface, the processor may control the display to concurrently display the second content in a main screen of the display and the first content in a sub-screen of the display in response to the received user input.

Abstract: Disclosed are a display device and a display method. The display device includes a display; and a controller configured to display a cursor at a location on the display corresponding to an input for controlling the display device, to detect that the cursor has entered an object region corresponding to an original location of an object displayed on the display, and to move the object toward the cursor that has entered the object region in response to detecting that the cursor has entered the object region.
