Abstract: A method and a display apparatus for generating and outputting an image generated to apply a special effect to a video are provided. The method includes outputting a video to a first area of a screen of the display apparatus, generating an image based on information comprised in the video, and outputting the generated image to a second area, surrounding the first area.

Abstract: A method for joining a network according to a user command and an associated group and a device using the same whereby, if it is determined that a command to join a network is input by a user, joining a network which will be formed together with another device that receives a command to join a network and belongs to a group relevant to a group of the device, among other devices existing around the device. Accordingly, it is not necessary to search for devices to join to a network one by one and thus a network is formed more easily.

Abstract: Provided are a touch-screen based device identification and information provision method and apparatus, and computer-readable recording mediums having recorded thereon programs for executing the touch-screen based device identification method and the information provision method. The device identification method for a touch screen device includes propagating a signal induced by touching a touch screen surface to an external device via the person, receiving information about the signal detected by the external device and an identification (ID) of the external device through a communication channel, and identifying the external device by using the received information about the detected signal and the received ID of the external device. Thus, the touch screen device and the external device can be connected to each other in real time by a simple and physical touch.

Abstract: A projection-based augmented reality system and a control method thereof are provided. The control method of an augmented reality system includes determining a conversion area to be converted from a work area based on a first gesture, acquiring a captured image of the determined conversion area, generating a virtual image of the determined conversion area from the acquired captured image, displaying the generated virtual image in the work area, and performing a manipulation function with respect to the displayed virtual image based on a second gesture.
