Abstract: A method of controlling content by using line interaction includes displaying a play bar region, representing a reproduction state of the content, on a touch screen, displaying an object, representing a function associated with reproduction of the content, near a reproduction time of the reproduction bar region, receiving a user input with respect to the play bar region through the touch screen, determining control information about the content, based on the received user input, and controlling the content according to the determined control information.

Abstract: A remote control apparatus for controlling a display apparatus, the remote control apparatus including a communicator configured to perform communication with the display apparatus; a user interface provided with a plurality of control surfaces each mapped to each of a plurality of display areas provided on a screen of the display apparatus; and a processor configured, in response to a user command being input through at least one of the plurality of control surfaces, to transmit a signal for controlling a display area mapped to a control surface to which the user command has been input.

Abstract: A display apparatus and a displaying method thereof are provided, where the display apparatus includes: a display unit configured to display contents and user interfaces (UIs); an input unit configured to receive a user command; and a controlling unit configured to control the display unit so that a first UI is displayed on one region of the display unit in the case in which a first touch is input through the input unit while the contents are displayed and the first UI is changed to a second UI to be indicated in the case in which a second touch having larger pressure than the first touch is input through the input unit while the first UI is displayed.

Abstract: A display apparatus and a method of providing information thereof are provided. The information providing method of the display apparatus includes displaying image content, recognizing at least one of a user motion and a user voice to obtain information related to the image content while the image content is displayed, generating query data according to the recognized at least one of the user motion and the user voice, and transmitting the query data to an external server, and in response to receiving information related to the image content from the external server in response to transmitting the query data, providing the received related information.

Abstract: According to one or more exemplary embodiments, a method of a remote controller for controlling a display device includes capturing an image of an object; detecting information about at least one of the shape, location, distance, and movement of the object based on the captured image; and transmitting the detected information to the display device.

Abstract: A user terminal apparatus includes a user interface (UI) including a physical guide to guide a user interaction regarding the UI, and a controller configured to provide a UI screen which corresponds to a modified context based on the physical guide in response to a context of an external apparatus being modified, and transmit a signal to the external apparatus to control the external apparatus in response to a touch interaction being input through the physical guide.
