Eye-gaze detecting device and eye-gaze detecting method

An eye-gaze detecting method for detecting an eye-gaze coordinate of a user in an input image from a capturing unit wearable on the user, said eye-gaze detecting method comprising:

• detecting an eye movement of the user to obtain eye movement information indicating the eye movement;
• receiving the input image, determining whether or not there is an object available as a calibration object in the input image, and providing a position coordinate indicating a position of the object;
• providing an instruction to the user to look at the calibration object indicated in the position coordinate in the case where the available object is determined to be included in the input image;
• calculating a calibration parameter with a use of the eye movement information of the user receiving the instruction, and the position coordinate of the calibration object, the calibration parameter being used for calibrating the eye movement information to the eye-gaze coordinate;
• and
• calibrating the eye movement information to the eye-gaze coordinate with a use of the calibration parameter calculated in said calculating.

An integrated circuit which detects an eye-gaze coordinate of a user in an input image from a capturing unit wearable on the user, said integrated circuit comprising:

• an eye movement detecting unit configured to detect an eye movement of the user to obtain eye movement information indicating the eye movement;
• a calibration object detecting unit configured to (i) receive the input image, (ii) determine whether or not there is an object available as a calibration object in the obtained input image, and (iii) provide a position coordinate indicating a position of the object in the case where the available object is determined to be included in the input image;
• an instructing unit configured to provide an instruction to the user to look at the calibration object indicated in the position coordinate;
• a calibration parameter calculating unit configured to calculate a calibration parameter with a use of the eye movement information of the user receiving the instruction from said instructing unit, and the position coordinate of the calibration object, the calibration parameter being used for calibrating the eye movement information to the eye-gaze coordinate;
• and
• a calibrating unit configured to calibrate the eye movement information to the eye-gaze coordinate with a use of the calibration parameter calculated by said calibration parameter calculating unit.
