Display device and method for controlling same
The present disclosure relates to a display device. The display device includes a display; a signal receiver configured to receive a user's voice signal through at least one of a plurality of devices; and a processor configured to: display an image of at least one of a plurality of programs on the display by executing the plurality of programs, identify a program corresponding to a device receiving the voice signal among the plurality of programs based on matching information set by the user regarding a mutual correspondence between the plurality of programs and the plurality of devices, in response to the user's voice signal received through any one of the plurality of devices, and control the identified program to operate according to a user command corresponding to the received voice signal. Thereby, it is possible to control a control target program to a user's intention according to a voice command even if a user who inputs the voice command does not separately designate the control target program.
1. A display device, comprising:
a display;
a voice input receiver; and
a processor configured to:
control the display to display an image of at least one of a plurality of programs by performing a function of the plurality of programs,
receive a user voice input through the voice input receiver from at least one of a plurality of devices,
identify a program corresponding to a device receiving the user voice input among the plurality of programs based on matching information corresponding to a mutual correspondence between the plurality of programs and the plurality of devices, and
control the identified program to perform a function corresponding to the received user voice input,
wherein the processor is further configured to, based on at least one of information on a category of a main function of the device receiving the user voice input or information on whether the device receiving the user voice input is a device set as a main device or a device set as a sub device, identify the program corresponding to the device among the plurality of programs.
2. The display device of claim 1 , further comprising:
a user input including the voice input receiver,
wherein the processor is configured to display a UI setting the matching information on the display, and set the matching information according to a user's input through the user input based on the UI.
3. The display device of claim 1 , wherein
the processor is configured to identify, as the program corresponding to the main device, a program executed in a mode in which an image is displayed among a plurality of programs being executed.
4. The display device of claim 1 , wherein the processor is configured to receive an execution command for a first program from a first device to execute the first program, and identify the first program as a program corresponding to the first device when the user voice input is received through the first device.
5. The display device of claim 1 , wherein the processor is configured to identify the program corresponding to the device receiving the user voice input based on location information of the device receiving the user voice input with respect to the display.
6. The display device of claim 1 , wherein the processor is configured to identify the program corresponding to the device receiving the user voice input by further referring to user's utterance content corresponding to the user voice input.
7. The display device of claim 1 , wherein the processor is configured to identify a user command corresponding to the received user voice input by further referring to information on the identified program.
8. A method for controlling a display device, comprising:
displaying an image of at least one of a plurality of programs by performing a function of the plurality of programs;
receiving a user voice input through a voice input receiver of the display device from any one of a plurality of devices;
identifying a program corresponding to a device receiving the user voice input among the plurality of programs based on matching information corresponding to a mutual correspondence between the plurality of programs and the plurality of devices; and
controlling the identified program to perform a function corresponding to the received user voice input,
wherein the identifying comprises, based on at least one of information on a category of a main function of the device receiving the user voice input or information on whether the device receiving the user voice input is a device set as a main device or a device set as a sub device, identifying the program corresponding to the device among the plurality of programs.
9. The method of claim 8 , further comprising:
displaying a UI setting the matching information; and
setting the matching information according to a user's input based on the UI.
10. The method of claim 8 , wherein, in the identifying, a program executed in a mode in which an image is displayed among a plurality of programs being executed is identified as a program corresponding to the main device.
11. The method of claim 8 , wherein in the identifying, an execution command for a first program from a first device is received to execute the first program, and the first program is identified as a program corresponding to the first device when the user voice input is received through the first device.
12. The method of claim 8 , wherein in the identifying, the program corresponding to the device receiving the user voice input is identified based on location information of the device receiving the user voice input with respect to the display.
13. The method of claim 8 , wherein in the identifying, the program corresponding to the device receiving the user voice input is identified by further referring to user's utterance content corresponding to the user voice input.
