5. The display apparatus of claim 4, wherein, when the item is a volume control menu and the volume control menu is selected, the control unit increases a volume of the display apparatus as the user motion of the one axis direction moves in a first direction, and decreases the volume of the display apparatus as the user motion of the one axis direction moves in a second direction that is opposite the first direction.

6. The display apparatus of claim 4, wherein, when the item is a channel change menu and the channel change menu is selected, the control unit increases a channel of the display apparatus as the user motion of the one axis direction moves in a first direction, and decreases the channel of the display apparatus as the user motion of the one axis direction moves in a second direction that is opposite the first direction.

7. The display apparatus of claim 1, further comprising:

a GUI generation unit that generates a three-dimensional GUI; and

a display unit that displays the three-dimensional GUI,

wherein the control unit changes a display status of the three-dimensional GUI according to the user motion of the three-dimensional space detected by the remote controller and received in the signal from the remote controller, and selects a menu displayed in the three-dimensional GUI.

8. The display apparatus of claim 1, wherein the control unit detects a center sensor or an outermost sensor in each axis direction based on locations of sensors detecting the user motion with respect to each of the plurality of the sensor arrays, and determines the user motion according to a location of the detected center sensor or outermost sensor.

9. The display apparatus of claim 1, further comprising:

a coordinate calculation unit that calculates a motion coordinate value of a user in the three-dimensional space according to the signal received from the remote controller,

wherein the control unit confirms the user motion according to the motion coordinate value calculated by the coordinate calculation unit.

10. The display apparatus of claim 1, wherein the plurality of the sensor arrays have different operating frequencies.

11. A method of controlling a display apparatus, the method comprising:

receiving a signal from a remote controller, the signal indicating a user motion detected by the remote controller in a three-dimensional space defined by a plurality of sensor arrays arranged in three axis directions of the three-dimensional space; and

controlling the display apparatus according to the signal indicating the user motion in the three-dimensional space.

12. The method of claim 11, wherein the controlling comprises:

changing display of a Graphical User Interface (GUI) displayed on a display of the display apparatus according to attributes of the user motion of the three-dimensional space detected by the remote controller and received in the signal from the remote controller,

wherein the attributes of the user motion comprise at least one of a motion direction, a motion distance, a motion speed, and a motion pattern.

13. The method of claim 11, wherein the controlling further comprises:
