Abstract: A terminal, includes: a communication unit to communicate with a synchronization server and a market; a short-range communication unit to communicate with a second terminal; and a controller to control the terminal, wherein the communication unit receives an application from the market, and communicates a request to the synchronization server to synchronize the application with the second communication terminal. A method for synchronizing an application, includes: transmitting, from a first communication terminal, information about an application to a synchronization server; searching for a second communication terminal associated with the first communication terminal; and retrieving a second application from a market based on the information about the application.

Abstract: Provided is a three-dimensional (3D) object processing apparatus. The apparatus is capable of interacting with a user and utilizes a stereoscopic effect of a 3D user interface (UI) as information. The apparatus includes a combination of various units, including but not limited to, a display panel, a sensing unit and control unit to effectuate interaction between a user and a 3D object sourced from the apparatus.
