Method for controlling device on the basis of eyeball motion, and device therefor

Abstract

A method of controlling a device is provided. The method includes receiving eye movement information of a user. A gazed position within a display area of the device is identified based on the eye movement information of the user. A position of a cursor corresponding to the gazed position is corrected based on the eye movement information. A control command corresponding to an area within the display area of the device is generated, based on the gazed position and the eye movement information. An operation of the device is controlled based on the control command.

         3 . The method of  claim 2 , wherein the dividing comprises dividing the display area based on an area where contents are displayed on the display area of the device. 
     
     
         4 . The method of  claim 1 , wherein the determining the control command comprises identifying the control command based on gazed position from the display to an area outside of the display. 
     
     
         5 . The method of  claim 1 , further comprising:
 displaying a control command selection window comprising a list of control commands on a display of the device;   sensing a selection of a control command from the control command list included in the control command selection window based on a user input via the displayed control command selection window; and   moving a cursor on the display of the device to a predetermined object based on the eye movement information of the user; and   wherein the determining comprises identifying the control command corresponding to the selected control command with respect to the object in response to an eyelid movement by the user.   
     
     
         6 . The method of  claim 1 , wherein the correcting the position of the cursor comprises:
 fixing a position of a cursor corresponding to the gazed position; and   moving a position of the cursor to correspond to a moved the gazed position, in response to the eye movement information of the user.   
     
     
         7 . The method of  claim 1 , wherein the correcting the position of the cursor comprises:
 receiving an eyelid movement information of the user;   determining to correct the position of the cursor based on the eye movement information and the eyelid movement information; and   matching the gazed position with the position of the cursor based on the eye movement information and the eyelid movement information.   
     
     
         8 . The method of  claim 1 , further comprising:
 displaying a previously set area around a cursor based on a user input; and   moving a cursor based on the gazed position with respect to the displayed area.   
     
     
         9 . The method of  claim 1 , further comprising:
 moving a cursor to an object in response to the cursor being moved based on the eye movement information to an area that is located within a previously set range of the object on the display of the device.   
     
     
         10 . A device for operating based on eye movements of a user, the device comprising:
 a memory storing instructions; and   a processor configured to execute the instructions to implement:
 an eye movement information receiver configured to receive information about eye movements of a user, identify a gazed position within a display area of the device based on the eye movement information of the user, and 
 an error corrector correct a position of a cursor corresponding to the gazed position based on the eye movement information; 
 a control command generator configured to generate a control command corresponding to an area within the display area of the device based on the gazed position and the eye movement information, control an operation of the device based on the control command. 
   
     
     
         11 . The device of  claim 10 , wherein the processor is configured to divide the display based on an area of the device where contents are displayed. 
     
     
         12 . The device of  claim 10 , wherein the processor is configured to identify the control command based on a movement of a gaze of the user as the gazed position moves from the display to an area outside of the display. 
     
     
         13 . The device of  claim 10 , further comprising:
 a display configured to display a control command selection window including a list of control commands corresponding to an eyelid movement of the user; and   a sensor configured to sense a user input via the displayed control command selection window and the eyelid movement of the user to select a control command from the list,   wherein the processor is configured to identify the control command corresponding to the sensed selected control command with respect to an object placed at a position of a cursor.   
     
     
         14 . The device of  claim 10 , wherein the processor configured to correct a position of a cursor on a display corresponding to a gaze of the user and match a position of a moved gaze of the user with the position of the cursor, in response to a movement of the gazed position. 
     
     
         15 . The device of  claim 10 , further comprising:
 a display configured to display a previously set area around a cursor based on a user input; and   an input adjuster,   wherein the processor is configured to move the cursor with respect to the displayed area, based on a direction of a position at which the gazed position is located.   
     
     
         16 . The device of  claim 10 , further comprising:
 a display configured to move a cursor on the display to an object on the display, in response to the cursor being moved based on the eye movement information to an area that is located within a previously set range of the object on the display of the device.   
     
     
         17 . A non-transitory computer readable medium comprising a computer program that is executable by a computer to perform the method of  claim 1 . 
     
     
         18 . The method of  claim 1 , wherein the gazed position and an eyelid movement information are determined based on the eye movement information, and
 the control command is generated based on the position of the gaze, the movement direction of the gaze, and the eyelid movement information.   
     
     
         19 . The device of  claim 10 , wherein the processor is configured to determine the gazed position and an eyelid movement information based on the eye movement information, and generate the control command based on the position of the gaze, the movement direction of the gaze, and the eyelid movement information. 
     
     
         20 . A non-transitory computer-readable medium having stored thereon instructions executable by a device to cause the device to:
 receive eye movement information of a user;   identify a gazed position within a display area of the device based on the eye movement information of the user;   correct a position of a cursor corresponding to the gazed position based on the eye movement information;   generate a control command corresponding to an area within the display area of the device, based on the gazed position and the eye movement information; and   control an operation of the device based on the control command.
