For example, a clock built in the remote controller 10 and a clock of a controller (not shown) connected to the UWB communication modules 21a, 21b, and 21c may be synchronized. The remote controller 10 may transmit the UWB signal together with the signal transmission time, and the controller connected to the UWB communication modules 21a, 21b, and 21c may compare time information included in the received signal with time when the signal is received. The distance from each UWB communication module 21a, 21b, 21c to the remote controller 10 can be calculated.

In addition, according to the exemplary embodiment, each of the UWB communication modules 21a, 21b, and 21c may transmit a request signal to the remote controller 10 at predetermined time intervals, and the remote controller 10 may transmit a UWB signal in response thereto. . The controller connected to the UWB communication modules 21a, 21b, 21c may calculate the distance from each UWB communication module 21a, 21b, 21c to the remote controller 10 by comparing the transmission time of the request signal and the reception time of the response signal. Can be.

The movement of the remote controller 10 with respect to the display device 30 may also be detected based on the distance from the UWB communication modules 21a, 21b, 21c to the remote controller 10 identified in the above manner. Therefore, when the user moves the remote control 10 in the space, such as shaking the remote control 10, move up, down, left and right, the control unit connected to the UWB communication modules (21a, 21b, 21c) according to the movement of the remote control 10 It can be recognized at. The recognized motion information, for example, shaking, horizontal movement, vertical movement, and the like, may be transmitted to a controller (not shown) of the display apparatus 30 and used as a control command of the display apparatus 30.

Even when there are four or more UWB communication modules, the UWB communication modules may be arranged to be spaced apart from each other as much as possible along the edges of the display device 30, and when four are used, as shown in FIG. 2, the display device 30 screen It can be placed at each vertex of.

According to an embodiment, the remote controller 10 may periodically transmit the UWB signal only when the motion recognition mode is executed. For example, when the activation button is mounted on the remote controller 10 and the activation button is pressed, the UWB signal may be transmitted to the UWB communication modules 21a, 21b, and 21c. Therefore, even if the remote controller 10 normally moves, the movement may not be recognized as a motion for inputting a command, but may be configured to be recognized as a command only when the user intends to.

3 is a block diagram showing the configuration of a remote controller 10 according to an embodiment of the present invention.

As shown in FIG. 3, the remote controller 10 or the remote control apparatus according to an embodiment of the present invention transmits a UWB signal to the UWB modules 21a, 21b, and 21c mounted on the display device 30. The module 11 may include a control unit 13 for controlling the operation of the UWB module 11 and a storage unit 14 for storing command codes for operating the control unit 13.

In addition, the remote controller 10 may be equipped with a plurality of key buttons mounted on a conventional remote controller, in addition to a user's motion input, and may further include a user input unit 12 including an input device such as a touch screen, a mouse, and a trackball. have.

In addition, one of the user input units 12 may be an input device for activating a motion recognition mode. For example, the motion recognition mode is activated only when one of the key buttons is pressed to periodically transmit the UWB signal to the UWB communication modules 21a, 21b, and 21c.

According to an embodiment of the present invention, the remote controller 10 may perform a function that can be performed by conventional remote controllers, that is, receive a key input and transmit an infrared signal to a display device, as described above. The module can also transmit signals. If necessary, the key input data may be transmitted by the infrared method, or the UWB signal may be transmitted to determine the position of the remote controller. In addition, after receiving a key input from a user without using an infrared method, it may be transmitted to a display device through a UWB signal.

The display device 30 may be a device having any display function, such as LCD, PDP, OLED, etc., and may be a digital TV or a monitor. In addition, the display device 30 may be a set-top box without a display unit.

The controller 22 may determine a movement of the remote controller 10 to determine a command for the display device 30 corresponding to the movement. For example, if it is determined that the remote controller 10 has moved left and right, it may be determined as a command to up or down the channel of the display device 30 (when there is a TV function). The controller 22 may transmit a key value corresponding to the channel up and down of the display apparatus 30 through the display interface 23. Therefore, the user can control the display device 30 by moving the remote controller 10 in the space.

In some embodiments, the motion recognition device 20 may be integrated with the display device 30. That is, the controller mounted in the display device 30 such as LCD or PDP performs the operation of the motion recognition device 20 and mounts the UWB modules to the outside, thereby recognizing the movement of the remote controller 10 as described above. The display device can be configured.
