1. An electronic device comprising:

  • a touch pad sensing a 3-dimensional interface, the touch pad being either concave-shaped or planar-shaped and embedded in a surface of the electronic device, the touch pad comprising an inner region and outer sensing region surrounding the inner region with the third dimension of the sensed 3-dimensional interface sensed by the outer sensing region according to an inward or outward movement sensed on the outer sensing region;

    a controller controlling a GUI (graphical user interface) in response to the 3-dimensional interface sensed by the touch pad; and

    a display displaying the GUI;

    wherein a sensed direction of the sensed third dimension is determined based on whether the sensed movement is an inward movement or an outward movement;

    wherein the 3-dimensional interface is sensed using the touch pad disposed in one side of the electronic device; and

    wherein the display and a contour of the touch pad are arranged substantially in a same plane of the surface where the touch pad is embedded.
