4 is a diagram showing a control method of the remote control device of FIG.

4A, it is exemplified that a pointer 205 corresponding to the remote control device 200 is displayed on the display 180. In the example of FIG.

The user can move or rotate the remote control device 200 up and down, left and right (FIG. 4B), and back and forth (FIG. 4C). The pointer 205 displayed on the display 180 of the video display device 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 control device 200 to the left, the pointer 205 displayed on the display 180 of the image display device also shifts to the left corresponding thereto.

Information on the motion of the remote control device 200 sensed through the sensor of the remote control device 200 is transmitted to the image display device. The image display apparatus can calculate the coordinates of the pointer 205 from the information on the motion of the remote control apparatus 200. [ The image display apparatus 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 180 while pressing a specific button in the remote control device 200. [ Thereby, the selected area in the display 180 corresponding to the pointer 205 can be zoomed in and displayed. Conversely, when the user moves the remote control device 200 close to the display 180, the selection area within the display 180 corresponding to the pointer 205 may be zoomed out and zoomed out. On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 approaches the display 180, the selection area may be zoomed in.

On the other hand, when the specific button in the remote control device 200 is pressed, it is possible to exclude recognizing the up, down, left, and right movement. That is, when the remote control apparatus 200 moves away from or approaches the display 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.
