[0086] In addition, the microphone 290 of the remote control device 200 can detect speech.

[0087] A plurality of microphones 290 may be provided.

[0088] Next, Fig. 4 described.

[0089] Fig. 4 is a view showing an example of use of a remote control device according to an embodiment of the present disclosure.

[0090] Fig. 4(a) illustrates that a pointer 205 corresponding to the remote control device 200 is displayed on the display 180.

[0091] A user can move or rotate the remote control device 200 vertically or horizontally. The pointer 205 displayed on the display 180 of the display device 100 corresponds to a movement of the remote control device 200. Since the corresponding pointer 205 is moved and displayed according to a movement in a 3D space, as shown in the drawing, the remote control device 200 can be referred to as a spatial remote control device.

[0092] Fig. 4(b) illustrates that when a user moves the remote control device 200, the pointer 205 displayed on the display 180 of the display device 100 is moved to the left in accordance with the movement of the remote control device 200.

[0093] Information about a movement of the remote control device 200, detected by a sensor of the remote control device 200, is sent 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 so that it corresponds to the calculated coordinates.

[0094] Fig. 4(c) illustrates that a user moves the remote control device 200 away from the display 180 while pressing a specific button on the remote control device 200. Thus, a selected area in the display 180 corresponding to the pointer 205 can be zoomed in and displayed enlarged.

[0095] On the other hand, when a user moves the remote control device 200 close to the display 180, a selection area in the display 180 corresponding to the pointer 205 can be zoomed out and displayed in a reduced size.

[0096] On the other hand, if the remote control device 200 is moved away from the display 180, a selection area can be zoomed out, and if the remote control device 200 is moved closer to the display 180, a selection area can be zoomed in.

[0097] Furthermore, when a specific button on the remote control device 200 is pressed, detection of vertical or horizontal movement can be excluded. In other words, when the remote control device 200 is moved away from or closer to the display 180, the upward, downward, left, or right movement cannot be detected, and only the forward and backward movement can be detected. While a specific button on the remote control device 200 is not pressed, only the pointer 205 is moved according to the upward, downward, left, or right movement of the remote control device 200.

[0098] Furthermore, the moving speed or moving direction of the pointer 205 may correspond to the moving speed or moving direction of the remote control device 200.

[0099] Furthermore, in this specification, a pointer refers to an object displayed on the display 180 in response to an operation of the remote control device 200. Therefore, in addition to the arrow shape displayed as the pointer 205 in the drawing, various object shapes are possible. For example, the above concept includes a dot, a cursor, a prompt, and a bold outline. Then, the pointer 205 can be displayed in accordance with a point of a horizontal axis and a vertical axis on the display 180, and can also be displayed in accordance with a plurality of points such as a line and a surface.

[0100] Fig. 5 shows an example of performing a cloud game by connecting multiple game manipulation devices to a display device.

[0101] In other words, Fig. 5 shows an example of performing a cloud game via a plurality of game manipulation devices 501, 503 and 505 without connecting a separate game console to the display device 100.

[0102] With reference to Fig. 5, the display device 100 may receive an image signal corresponding to a game image from a cloud server 50 and display a game image 500 on the display 180 based on the received image signal.

[0103] The network interface 133 of the display device 100 can communicate with the cloud server 50 via IP communication.

[0104] In addition, a plurality of game manipulation devices 501, 503 and 505 are connected to each other by wired or wireless communication in the display device 100.

[0106] When connected via cable, the Universal Serial Bus (USB) communication standard can be used, but this is just an example.

[0107] The majority of game manipulation devices 501, 503 and 505 may be of the same brand or manufactured by the same manufacturer.

[0108] Fig. 5 shows an example in which three game manipulation devices 501, 503 and 505 are connected to a display device 100 via Bluetooth and a game is played, but two or four or more game manipulation devices may be connected and the game is played.

[0109] The game manipulation device sends a manipulation command to the display device 100, the display device 100 sends the received manipulation command to the cloud server 50, and the cloud server 50 can send a response signal corresponding to the server command (50) to the display device 100.

[0110] Each of the plurality of game manipulation devices 501, 503 and 505 may include a plurality of LEDs 501a, 503a, 505a, respectively.

[0111] Each LED can be a notification light to indicate a change in the status of the match-fixing device.

[0112] In particular, the LED may flash or emit a specific color when the battery is low or disconnected from the display device 100.

[0113] Fig. 6 is a flowchart for explaining a method of operating a display device according to an embodiment of the present disclosure.

[0114] The following describes the embodiment of Fig. 6 based on the embodiment of Fig. 5 described.

[0115] With reference to Fig. 6, a plurality of game manipulation devices are connected to the display device 100 (S601).

[0118] The wireless communication interface 173 of the display device 100 may include a Bluetooth communication circuit.

[0119] Meanwhile, the display device 100, as shown in Fig. 5, is connected to a cloud server 50 via a network and displays game images 500 received from the cloud server 50 on the display 180.

[0120] When establishing a Bluetooth connection with a plurality of game manipulation devices, the display device 100 can obtain the Bluetooth address of each game manipulation device. The Bluetooth address can contain information for identifying the game manipulation device.

[0121] The display device 100 can store the Bluetooth address of each game manipulation device and identify each game manipulation device via the Bluetooth address.

[0122] The controller 170 of the display device 100 determines whether there is a device among the plurality of game manipulation devices whose battery level is lower than the reference level (S603).

[0123] The game manipulation device may send battery information indicating a low battery level to the display device 100 when the battery charge level is lower than the reference charge level.

[0124] The controller 170 may detect the presence of a game manipulation device with a battery level below the reference battery level based on the received battery information and the Bluetooth address of the device that sent the battery information.

[0125] In one embodiment, the reference charge amount may be a charge amount corresponding to 30%, but this is only an example.

[0126] The controller 170 of the display device 100 determines whether the device name of a game manipulation device with a battery charge amount lower than the reference charge amount is stored in the memory 140 (S605).

[0127] In one embodiment, the controller 170 may determine whether the device name of the game manipulation device experiencing a battery shortage is stored in the memory 140.

[0128] The memory 140 may match and then store the device name of the game manipulation device and the identification information of the game manipulation device.

[0129] The device name of the match-fixing device can be an edited name based on user input.

[0130] The identification information of the game manipulation device can be either the Bluetooth address or the brand name or manufacturer name of the game manipulation device.

[0131] Fig. 7 to 9 are views for explaining a method of discriminating game manipulation devices when the same type of game manipulation devices is connected to a display device according to an embodiment of the present disclosure.

[0132] With reference to Fig. 7, the controller 170 of the display device 100 may display a dialog window 700 for entering a device name on the display 180 when a plurality of game manipulation devices 501, 503, and 505 of the same brand, model, or type are connected to the display device 100.

[0133] A dialog window 700 may include text 701 informing that a plurality of game manipulation devices (501, 503 and 505) of the same make or model are connected to the display device 100 and that editing of the device name is possible, as well as an OK button 703 and a Cancel button 705.

[0134] The controller 170 may display a dialog window 700 when a plurality of game manipulation devices of the same make or model are connected.

[0135] When a command to select the OK button 703 of the dialog window 700 is received, the controller 170 may display a virtual keyboard window 800 for entering the device name of the game manipulation device on the display 180, as shown in Fig. 8 shown.

[0136] The controller 170 may receive a command from a remote control device 200 to select the OK button 703.

[0137] The controller 170 may receive the device name of each game manipulation device via the virtual keyboard window 800.

[0138] The controller 170 may sequentially disconnect each of the plurality of game manipulation devices 501, 503, and 505.

[0139] For example, the controller 170 may disconnect the first game manipulation device 501. The first game manipulation device 501 may flash the first LED 501a when the connection to the first game manipulation device 501 is disconnected.

[0140] The controller 170 may display a message on the display 180 requesting the device name of the game manipulation device whose LED is flashing.

[0141] The controller 170 may obtain the first device name of the first game manipulation device 501 via the virtual keyboard window 800, compare the first device name with the identification information of the first game manipulation device 501, and then store it in the memory 140.

[0142] The controller 170 may obtain the first device name by receiving an input from the remote control device 200 to select a particular key of the virtual keyboard window 800.

[0143] The identification information of the first game manipulation device 501 may be the first Bluetooth address.

[0144] The user can reconnect the first game manipulation device 501 and the display device 100 by entering the device name of the first game manipulation device 501 and then selecting any button of the first game manipulation device 501.

[0145] In the same way, the second game manipulation device 503 and the third game manipulation device 505 can be sequentially disconnected and the second device name and the third device name can be retrieved.

[0146] The memory 140 may match the second device name with the identification information of the second game manipulation device 503 and then store it therein, and may match the third device name with the identification information of the third game manipulation device 505 and then store it therein.

[0147] With reference to Fig. 9, a table 900 is shown in which a plurality of device names are matched and then stored for each of a plurality of game manipulation devices 501, 503, and 505.

[0148] For example, AA:BB:CC, the identification information of the first game manipulation device 501, matches the first device name (John), DD:EE:FF, the identification information of the second game manipulation device 503, matches the second device name (Sam), and GG:HH:KK, the identification information of the third game manipulation device 505, matches the third device name (Peter).

[0149] Each device name can later be used to notify users about which device had a low battery level.

[0150] Again, Fig. 6 explained.

[0151] When the device name of a game manipulation device whose battery level is lower than the reference level is stored in the memory 140, the controller 170 of the display device 100 outputs a low battery notification including the device name on the display 180 (S607).

[0152] The controller 170 may determine whether there is a device name that matches the identification information of a game manipulation device that has reported a low battery status among a plurality of game manipulation devices.

[0153] For example, when the controller 170 receives battery information indicating a low battery level from the third game manipulation device 505, the controller may determine whether a device name matching GG:HH:KK, which is the identification information of the third game manipulation device 505, is present from the memory 140.

[0154] The controller 170 may read the third device name (Peter) matching GG:HH:KK, which is the identification information of the third game manipulation device 505, from the memory 140.

[0155] The controller 170 may display a notification on the display 180 indicating a low battery status of the game manipulation device corresponding to the read third device name (Peter).

[0156] Fig. 10 is a view for explaining an example of displaying a low battery notification including the name of a game manipulation device when a low battery occurs in one of a plurality of game manipulation devices according to an embodiment of the present disclosure.

[0157] With reference to Fig. 10, a display device 100 displays a game image (500) in a state in which it is connected to a plurality of game manipulation devices (501, 503 and 505).

[0158] The display device 100 may receive battery information indicating a low battery status from the third game manipulation device 505 via Bluetooth.

[0159] In other words, when the battery level is lower than the reference level, the third game manipulation device 505 may send battery information indicating a low battery level to the display device 100.

[0160] The third game manipulation device 505 may send battery information indicating a low battery condition to the display device 100 only when the battery level is lower than the reference level, and may not send battery information to the display device 100 when the battery level is equal to or greater than the reference level.

[0161] The display device 100 may determine the low battery level of the third game manipulation device 505 based on the battery information received from the third game manipulation device 505.

[0162] The display device 100 may detect that it has received battery information from the third game manipulation device 505 via a Bluetooth address that it already knows through Bluetooth communication with the third game manipulation device 505.

[0163] The display device 100 may obtain the third device name (Peter) that matches the Bluetooth address (GG:HH:KK) representing the identification information of the third game manipulation device 505 from the memory 140.

[0164] The display device 100 may display a low battery notification 1000 including the received third device name (Peter) on the display 180.

[0165] In this way, according to an embodiment of the present disclosure, even if a plurality of game manipulation devices of the same brand or model are connected, the user can easily identify which game manipulation device has a low battery based on a low battery notification (1000) during the game.

[0166] Again, Fig. 6 explained.

[0167] The controller 170 of the display device 100 sends a disconnection command to the game manipulation device when the device name of the game manipulation device whose battery level is lower than the reference level is not stored in the memory 140 (S609). The control 170

[0168] The controller 170 may send a Bluetooth disconnect command to the game manipulation device to notify the game manipulation device of a low battery condition where the battery charge level is lower than the reference charge level.

[0169] The game manipulation device's LED may flash in response to a disconnect command.

[0170] The controller 170 of the display device 100 displays on the display 180 a low battery notification including the brand name (or manufacturer name) of the game manipulation device whose battery level is below the reference battery level (S611).

[0171] Although the controller 170 can detect which game manipulation device has a low battery level, because the device name of the device is not stored, the device name may not be output.

[0172] The controller 170 may send a disconnect command to a game manipulation device in a low battery condition, causing the game manipulation device's LED to flash.

[0173] The controller 170 may display a low battery notification including the brand name or model name of the game manipulation device on the display 180.

[0174] Fig. 11 is a view for explaining an example of displaying a low battery notification including the brand name of the game manipulation device when a low battery occurs in one of a plurality of game manipulation devices according to an embodiment of the present disclosure.

[0175] With reference to Fig. 11, the display device 100 may receive battery information indicating a low battery level from a third game manipulation device 505 among a plurality of game manipulation devices 501, 503, and 505.

[0176] The display device 100 may send a Bluetooth disconnection command to the third game manipulation device 505 when the device name of the third game manipulation device 505 is not searched in the memory 140.

[0177] At the same time, the display device 100 may display a low battery notification 1100 including the brand name of the third game manipulation device 505 on the display 180.

[0178] Meanwhile, the third game manipulation device 505 may flash the LED 505a upon receiving a Bluetooth disconnection command.

[0179] The user can easily detect that the battery of the third game manipulation device 505 with the flashing LED 505a is low by checking the low battery notification 1100.

[0180] Again, Fig. 6 explained.

[0181] The controller 170 of the display device 100 determines whether a reconnection request is received from the game manipulation device (S613), and if a reconnection request is received, performs a reconnection process (S615).

[0182] The controller 170 may resume Bluetooth communication when it receives a Bluetooth reconnection request from a game manipulation device for which the device name is not stored.

[0183] The user can reconnect the display device 100 and the game manipulation device by charging or replacing the battery of the game manipulation device whose battery level is low.

[0184] The user can reconnect the display device 100 and the game manipulation device by inputting a key provided on the game manipulation device.

[0185] According to one embodiment of the present disclosure, the method described above may be implemented as processor-readable code on a program recording medium. Examples of media that the processor can read include ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage devices.
