[0088] The user can recognize whether the output interface (250) is manipulating the user input interface (230) or controlling the display device (100).

[0089] For example, the output interface (250) may include an LED (251) that lights up when the user input interface (230) is operated or a signal is transmitted and received with the display device (100) via the wireless communication unit (225), a vibrator (253) that generates vibrations, a speaker (255) that outputs sound, or a display (257) that outputs images.

[0090] In addition, the power supply circuit (260) supplies power to the remote control device (200), and power waste can be reduced by stopping the power supply when the remote control device (200) does not move for a predetermined period of time.

[0091] The power supply circuit (260) can resume power supply when a predetermined key provided in the remote control device (200) is operated.

[0092] The memory (270) can store various types of programs, application data, etc. required for the control or operation of the remote control device (200).

[0093] When the remote control device (200) wirelessly transmits and receives signals through the display device (100) and the RF circuit (221), the remote control device (200) and the display device (100) transmit and receive signals through a predetermined frequency band.

[0094] The controller (280) of the remote control device (200) can store and reference information regarding the frequency band that can wirelessly transmit and receive signals with the display device (100) paired with the remote control device (200) in the memory (270).

The controller (280) can transmit a signal corresponding to a predetermined key operation of the user input interface (230) or a signal corresponding to the movement of the remote control device (200) sensed by the sensor (240) to the display device (100) via the wireless communication unit (225).

[0096] Additionally, the microphone (290) of the remote control device (200) can acquire voice.

[0097] A plurality of microphones (290) may be provided.

[0098] Next, Figure 4 is described.

[0099] Figure 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.

[0100] Figure 4 (a) illustrates that a pointer (205) corresponding to a remote control device (200) is displayed on a display (180).

[0101] The user can move or rotate the remote control device (200) up and down, left and right. The pointer (205) displayed on the display (180) of the display device (100) corresponds to the movement of the remote control device (200). This remote control device (200) can be called a space remote control because, as shown in the drawing, the pointer (205) moves and is displayed according to the movement in 3D space.

[0102] Figure 4 (b) illustrates that when a user moves the remote control device (200) to the left, the pointer (205) displayed on the display (180) of the display device (100) also moves to the left correspondingly.

[0103] Information about the movement of the remote control device (200) detected 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 movement of the remote control device (200). The display device (100) can display the pointer (205) to correspond to the calculated coordinates.

[0104] Figure 4 (c) illustrates a case where a user moves the remote control device (200) away from the display (180) while pressing a specific button within the remote control device (200). As a result, a selection area within the display (180) corresponding to the pointer (205) can be zoomed in and displayed in an enlarged manner.

[0105] Conversely, when the user moves the remote control device (200) closer to the display (180), the selection area within the display (180) corresponding to the pointer (205) may be zoomed out and displayed in a reduced size.

[0106] Meanwhile, when the remote control device (200) moves away from the display (180), the selection area may be zoomed out, and when the remote control device (200) moves closer to the display (180), the selection area may be zoomed in.

[0107] In addition, when a specific button within the remote control device (200) is pressed, recognition of up, down, left, and right movements may be excluded. That is, when the remote control device (200) moves away from or toward the display (180), up, down, left, and right movements may not be recognized, and only forward and backward movements may be recognized. When a specific button within the remote control device (200) is not pressed, only the pointer (205) moves in accordance with the up, down, left, and right movements of the remote control device (200).

[0108] Meanwhile, the movement speed or movement direction of the pointer (205) can correspond to the movement speed or movement direction of the remote control device (200).

[0109] Meanwhile, the pointer in this specification refers to an object displayed on the display (180) in response to the operation of the remote control device (200). Accordingly, objects of various shapes other than the arrow shape illustrated in the drawing can be used as the pointer (205). For example, the pointer may be a concept including a point, a cursor, a prompt, a thick outline, etc. In addition, the pointer (205) may be displayed corresponding to one point on the horizontal or vertical axis on the display (180), or may be displayed corresponding to multiple points such as lines or surfaces.
