The pointer 205 displayed on the display unit 180 of the display device 100 corresponds to the movement of the remote control device 200. [ In this remote control device 200, as shown in the figure, since the pointer 205 is moved according to the movement in the 3D space, it can be called a space remote controller.

4B illustrates that when the user moves the remote controller 200 to the left, the pointer 205 displayed on the display unit 180 of the display apparatus 100 moves to the left correspondingly.

Information on the motion of the remote control device 200 sensed through the sensor of the remote control device 200 is transmitted to the display device 100. The display device 100 can calculate the coordinates of the pointer 205 from the information about the motion of the remote control device 200. [ The display device 100 can display the pointer 205 so as to correspond to the calculated coordinates.

4C illustrates a case where the user moves the remote control device 200 away from the display unit 180 while the specific button in the remote control device 200 is depressed. Thereby, the selected area in the display unit 180 corresponding to the pointer 205 can be zoomed in and displayed.

Conversely, when the user moves the remote control apparatus 200 close to the display unit 180, the selection area within the display unit 180 corresponding to the pointer 205 may be zoomed out and displayed.

On the other hand, when the remote control device 200 moves away from the display unit 180, the selected area is zoomed out, and when the remote control device 200 approaches the display unit 180, the selected area may be zoomed in.

Further, the recognition of the upward, downward, and leftward / rightward movement can be excluded when a specific button in the remote control device 200 is pressed. That is, when the remote control device 200 moves away from or approaches the display unit 180, it is not recognized that the up, down, left, and right movements are recognized, and only the forward and backward movements are recognized. Only the pointer 205 is moved in accordance with the upward, downward, leftward, and rightward movement of the remote control device 200 in a state where the specific button in the remote control device 200 is not pressed.

On the other hand, the moving speed and moving direction of the pointer 205 may correspond to the moving speed and moving direction of the remote control device 200.

The pointer in the present specification means an object displayed on the display unit 180 in correspondence with the operation of the remote control device 200. [ Therefore, various shapes of objects other than the arrow shapes shown in the drawings are possible with the pointer 205. [ For example, it can be a concept that includes points, cursors, prompts, thick outlines, and so on. The pointer 205 may be displayed corresponding to a point on a horizontal axis or a vertical axis on the display unit 180 or may be displayed corresponding to a plurality of points such as a line or a surface Do.
