Abstract: The interaction system includes: an infrastructure image sensor-based 3D cloud restoration module configured to create a 3D cloud point using a multi-view image received from an infrastructure sensor; a real-time 3D map creation and learning update module configured to generate subset data composed of point clouds into a 3D map using 3D point information received from the infrastructure image sensor-based 3D cloud restoration module; an object estimation module in a 3D space configured to recognize and track an object existing in a 3D space based on the 3D map received from the real-time 3D map creation and learning update module; and a dangerous situation recognition and interaction module in space configured to receive information on an object existing in the 3D space from the object estimation module in the 3D space, recognize a dangerous situation, and provide dangerous situation related information.

Abstract: Provided are a method and a mobile terminal for simultaneously displaying at least two application windows on a display unit of a mobile terminal. The method may include displaying a first application window associated with a first application on an entire display area of the display unit, receiving a multi_screen mode initiation input from a user, dividing a display area of the display unit into at least two display areas including a first display area and a second display area in response to the multi_screen mode initiation input, and displaying the first application window and a second application window on the at least two display areas, respectively, in a multi_screen mode.

Abstract: Apparatus and method for displaying information as a background of a user interface. In order to display the information as the background of a user interface, information such as user interest information may be received from a user. Based on the received information, contents may be retrieved. Then, the background of the user interface may be formed with at least one image. Each image of the at least one image may represent a respective one of the retrieved contents. The user interface having the background formed with the at least one image may be displayed.

Abstract: Provided are a mobile terminal and a method for transferring objects from a source application window to a destination application window, which are simultaneously displayed on a display unit of a mobile terminal. The method may include displaying the first application window and the second application window simultaneously on the display unit in response to a multi_screen mode initiation input, and transferring at least one of a portion of and an entire object in one of the first application window and the second application window to another application window in response to an object transferring mode initiation input.

Abstract: Apparatus and/or method for providing a user interface in a user equipment. At least one background screen of the user interface may be formed from at least one image. Each of the at least one background screen may be associated with a respective application of the user equipment, and each image of the at least one image may represent a respective content associated with the respective application. Then, when a user input at least one of a predetermined gesture input and a predetermined key input, a main menu which allows the user to select a desired application to be executed may be displayed over a current display screen. When a selection input for selecting the desired application is received from the displayed main menu, the user interface having the background screen formed from the at least one image corresponding to the selected desired application may be displayed.

Abstract: Apparatus and method for providing a user interface for media contents in a user equipment. In order to provide the user interface, the background screen of the user interface may be formed from at least one image. Each image of the at least one image may represent a respective one of the retrieved media contents. The user interface having the background screen formed from the at least one image may be displayed. A desired image may be selected from the at least one image of the displayed user interface, and a desired media content corresponding to the selected desired image may be played.
