Three dimensional graphic user interface, method and apparatus for providing the user interface

A 3D(Dimensional) GUI(Graphic User Interface), and a device and a method for offering the same are provided to intuitively transfer information and satisfy sensitiveness of a user by moving an object group including an object selected from the user to a user side and changing a viewpoint to a corresponding object group side. A control module(530) generates a 3D interface space comprising a plane and an axis perpendicular to the plane, and multiple objects arranged in the 3D interface space. A user interface module(550) arranges the object groups including the objects in the 3D interface space and moves the object group including the object selected by the user among the arranged object groups along the axis. The object group includes an upper object including multiple upper objects and multiple lower objects for the upper object selected by the user.
