Display apparatus and control method thereof

Abstract

A display apparatus includes a first recognition unit to recognize a gaze of a user; a second recognition unit to recognize a command from the user; a controller to determine whether the recognized gaze is within a predetermined recognition region, to control entry into an interactive mode upon determining that the recognized gaze is within the predetermined recognition region, and to selectively control a plurality of functions based on the recognized gaze and command; and a display unit to display an image corresponding to the interactive mode and an image corresponding to the selectively controlled function.

What is claimed is: 
     
         1 . A display apparatus comprising:
 a first recognition unit to recognize a gaze of a user;   a second recognition unit to recognize a command from the user;   a controller to determine whether the recognized gaze is within a predetermined recognition region, to control entry into an interactive mode upon determining that the recognized gaze is within the predetermined recognition region, and to selectively control a plurality of functions based on the recognized gaze and command; and   a display unit to display an image corresponding to the interactive mode and an image corresponding to the selectively controlled function.   
     
     
         2 . The display apparatus according to  claim 1 , wherein the second recognition unit recognizes at least one signal selected from between a motion and voice of the user and recognizes an operation command corresponding to the at least one recognized signal. 
     
     
         3 . The display apparatus according to  claim 2 , wherein, when a motion is recognized in a state in which the gaze is within the predetermined region, the controller confirms a command corresponding to the recognized motion and controls execution of a function corresponding to the confirmed command. 
     
     
         4 . The display apparatus according to  claim 2 , wherein, when a voice is recognized in a state in which the gaze is within the predetermined region, the controller confirms a command corresponding to the recognized voice and controls execution of a function corresponding to the confirmed command. 
     
     
         5 . The display apparatus according to  claim 1 , wherein the functions comprise at least one selected from among reproduction of an external broadcast signal, reproduction of external content, a reproduction mode, and a screen adjustment mode. 
     
     
         6 . The display apparatus according to  claim 1 , further comprising:
 a communication unit to receive a sound signal transmitted from an external remote controller,   wherein the second recognition unit recognizes a voice from the received sound signal.   
     
     
         7 . A control method of a display apparatus comprising:
 recognizing a gaze of a user;   determining whether the recognized gaze is within a predetermined recognition region;   entering an interactive mode upon determining that the recognized gaze is within the predetermined recognition region;   displaying a plurality of recognition modes for interaction with the user;   determining a recognition mode corresponding to a position of the recognized gaze from among the displayed recognition modes;   recognizing a command based on the determined recognition mode; and   executing a function corresponding to the recognized command,   wherein the recognizing the command based on the determined recognition mode comprises
 recognizing at least one signal selected from between a motion and voice of the user; and 
 recognizing the command corresponding to the at least one recognized signal. 
   
     
     
         8 . The control method according to  claim 7 , wherein the recognizing the command corresponding to the at least one recognized signal comprises:
 when the motion is recognized in a state in which the gaze is within a predetermined region, recognizing the command corresponding to the recognized motion.   
     
     
         9 . The control method according to  claim 7 , wherein the recognizing the command corresponding to the at least one recognized signal comprises:
 when the voice is recognized in a state in which the gaze is within a predetermined region, recognizing the command corresponding to the recognized voice.   
     
     
         10 . The control method according to  claim 7 , further comprising:
 receiving the voice signal transmitted from an external remote controller.
