User interface apparatus using axes of three dimension and user interface apparatus using planes of two dimension shared an axis of three dimension

PURPOSE: A UI device using an element expressed on the 3D axis and UI device using a 2D plane which has a 3D axis as an boundary is provided to minimize a user inptut when selecting a menu of a mobile communication terminal. CONSTITUTION: A first parameter(110) is expressed at least one location on one 3D axis among a 3D(Dimensional) shaft. A second parameter(120) is expressed at least one location on other 3D shaft which is different with a 3D shaft that the first parameter is expressed. A manipulation unit(130) controls movement of the first or the second parameter. A search unit(140) searches information which accords with a condition of parameters.
