Device and method for controlling mouse using gaze recognition

1 . A processor-implemented method for controlling a mouse using gaze recognition, the method comprising:

measuring a distance between eyes of a user and a gaze recognizer in response to a user gazing at an object displayed on a display;

setting a size of a mouse pointer based on at least one of the measured distance and a display resolution;

performing calibration based on the set size of the mouse pointer;

displaying the mouse pointer based on the calibration on a display;

determining occurrence of mouse shaking via gaze recognition by the gaze recognizer; and

controlling a movement of the mouse pointer based on the mouse shaking,

wherein the setting of the size of the mouse pointer comprises:

setting a minimum size of the mouse pointer based on the measured distance;

checking a maximum size of the pointer based on a button layout within a screen;

checking a display resolution-pointer size;

determining whether the display resolution-pointer size is smaller than the minimum size of the mouse pointer based on the measured distance; and

increasing the size of the pointer within the screen such that the pointer is displayed in a physical minimum size in response to the display resolution-pointer size being smaller than the pointer minimum size.

2 . The method of claim 1 , wherein the performing of the calibration based on the set size of the mouse pointer comprises:

performing the calibration for eye location and movement based on the mouse shaking;

determining a shaking range based on a gazed point based on the user gaze; and

creating the size of the mouse pointer based on the determined shaking range.

3 . The method of claim 2 , wherein the displaying of the mouse pointer created based on the calibration on the display comprises:

determining whether the display resolution-pointer size is equal to or smaller than a maximum size of the mouse pointer created by the calibration;

limiting the size of the mouse pointer up to the maximum size in response to the display resolution-pointer size not being equal to or smaller than the maximum size of the mouse pointer created by the calibration; and

displaying the mouse pointer whose size is limited up to the maximum size on the display.

4 . The method of claim 3 , wherein the controlling of the movement of the mouse pointer based on the mouse shaking comprises:

determining whether the mouse shaking occurs;

determining whether the shaking range is greater than an area of the created mouse pointer in response to the mouse shaking;

controlling the mouse pointer to move in response to the shaking range being greater than the area of the mouse pointer; and

controlling a location of the mouse pointer to be fixed in response to the shaking range being smaller than the area of the mouse pointer.

5 . The method of claim 4 , further comprising:

fixing an existing mouse pointer location when the shaking range is greater than an area of the mouse pointer.

6 . A device for controlling a mouse using gaze recognition, the device comprising:

a display configured to display data, information, or contents on a screen;

a gaze recognizer configured to capture a facial image of a user gazing at the screen of the display to recognize a user's gaze;

a distance measurer configured to measure a distance between user's eyes and the gaze recognizer; and

a mouse controller configured to, in response to a user gazing at an object displayed on the display:

control a mouse pointer based on the results recognized and measured by the gaze recognizer and the distance measurer;

set a size of the mouse pointer based on at least one of the measured distance and a display resolution;

perform calibration based on the set size of the mouse pointer;

display the mouse pointer based on the calibration on the display;

determine occurrence of mouse shaking via gaze recognition by the gaze recognizer; and

control a movement of the mouse pointer based on the mouse shaking,

wherein the mouse controller is further configured to:

set a minimum size of the mouse pointer based on the measured distance;

check a maximum size of the pointer based on a button layout within the screen;

check a display resolution-pointer size;

determine whether the display resolution-pointer size is smaller than the minimum size of the mouse pointer based on the measured distance; and

increase the size of the pointer within the screen such that the pointer is displayed in a physical minimum size in response to the display resolution-pointer size being smaller than the pointer minimum size.

7 . The device of claim 6 , wherein the mouse controller is further configured to:

perform the calibration for eye location and movement based on the mouse shaking;

determine a shaking range based on a gazed point based on the user gaze; and

create the size of the mouse pointer based on the determined shaking range.

8 . The device of claim 7 , wherein the mouse controller is further configured to:

determine whether the display resolution-pointer size is equal to or smaller than a maximum size of the mouse pointer created by the calibration;

limit the size of the mouse pointer up to the maximum size in response to the display resolution-pointer size not being equal to or smaller than the maximum size of the mouse pointer created by the calibration; and

display the mouse pointer whose size is limited up to the maximum size on the display.

9 . The device of claim 8 , wherein the mouse controller is further configured to:

determine whether the mouse shaking occurs;

determine whether the shaking range is greater than an area of the created mouse pointer in response to the mouse shaking;

control the mouse pointer to move in response to the shaking range being greater than the area of the mouse pointer; and

control a location of the mouse pointer to be fixed in response to the shaking range being smaller than the area of the mouse pointer.

10 . The device of claim 9 , wherein the mouse controller is further configured to fix an existing mouse pointer location when the shaking range is greater than the area of the mouse pointer.
