Display apparatus and control method thereof

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.

A display apparatus comprising:

• a tuner to receive an external broadcast signal;
• a signal processor to separate the broadcast signal into an image signal having image information and a sound signal having sound information and to signal-process the separated image signal and sound signal;
• a recognition unit to recognize a gaze of a user;
• a controller to determine whether the recognized gaze is within a predetermined recognition region and to control entry into an interactive mode upon determining that the recognized gaze is within the predetermined recognition region;
• a display unit to display the signal-processed image signal and an image corresponding to the interactive mode;
• and
• a sound output unit to output the signal-processed sound signal.

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;
• executing the determined recognition mode to recognize a command from the user;
• and
• executing a function corresponding to the recognized command.

A control method of a display apparatus comprising:

• entering an interactive mode by determining a recognized user's gaze is directed to a predetermined recognition region;
• displaying a plurality of recognition modes for interaction with the user;
• determining a selected recognition mode corresponding to a position of the user's gaze from among the displayed recognition modes;
• executing a function corresponding to the selected recognition mode.
