However, since the home appliance has various functions, it is difficult for a user to understand all functions of the home appliance.
Therefore, there is a need for a method of identifying a function of a home appliance according to a user's intention and recommending a function suitable for the intention.
The present invention aims to provide a display device capable of interlocking an operation of a home appliance suitable for a handling method based on an object handling method.
The present invention aims to allow a user to efficiently handle an object by reflecting a corresponding matter even if the user replaces a home appliance or a home appliance is updated.
A display device for controlling a home appliance by using voice recognition according to an embodiment of the present invention may include a display unit, a wireless communication unit configured to wirelessly communicate with the home appliance, and a control unit configured to: receive a voice command; when the intention of the received voice command is to request an object handling method, determine an operation mode of the home appliance for handling an object based on information of the object; and transmit, to the home appliance, a control command for operating the home appliance in the determined operation mode.
An artificial intelligence server for controlling a home appliance by using voice recognition according to an embodiment of the present invention may include a memory configured to store object information, a communication unit configured to receive a voice command from a display device, and a processor configured to: when the intention of the received voice command is to request an object handling method, determine an operation mode of the home appliance for handling an object based on object information; and transmit, to an external server, a control command for operating the home appliance in the determined operation mode.
According to various embodiments of the present disclosure, an operation mode of a home appliance optimized for handling an object may be set only by uttering a voice command for handling an object. Therefore, a user can efficiently manage the object without needing to know all the functions of the corresponding home appliance.
In addition, even if the home appliance is replaced or updated, the user may set an operation mode of the home appliance suitable for handling the object by taking into account the change.
