Information processing apparatus, method, and storage medium storing program

A non-transitory computer readable storage medium having a program stored thereon for controlling a computer of an information processing apparatus which includes a display unit and which detects a movement amount of a gaze of an eye from captured image data supplied from an image capturing unit connected therewith, the program being executable to control the computer to function as units comprising:

• a first image detection unit that detects, as a first image, an image indicative of a specific part of an eye in captured image data supplied from the image capturing unit;
• a first detection unit that identifies a position of the first image in the captured image data;
• a second image detection unit that detects, as a second image, an image indicative of an object of a specific shape reflected by the eye from the captured image data;
• a second detection unit that identifies a position of the second image in the captured image data;
• an eye-gaze movement amount detection unit that detects a movement amount of a gaze of the eye captured by the image capturing unit based on a relationship between positions of the first image and the second image;
• a mouse pointer control unit that causes a mouse pointer displayed on the display unit to move within the display unit based on the movement amount of the gaze of the eye detected by the eye-gaze movement amount detection unit;
• and
• a reference shift amount setting unit that sets a reference shift amount that is used as a reference for a variation of the position of the first image and the position of the second image;
• wherein the reference shift amount setting unit updates the reference shift amount in accordance with movement of the mouse pointer.

An information processing method of an information processing apparatus including a display unit for detecting a movement amount of a gaze of an eye from captured image data supplied from an image capturing unit, the method comprising;

• detecting, as a first image, an image indicative of a specific part of an eye in captured image data supplied from the image capturing unit;
• identifying a position of the first image in the captured image data;
• detecting, as a second image, an image indicative of an object of a specific shape reflected by the eye from the captured image data;
• identifying a position of the second image in the captured image data;
• detecting a movement amount of a gaze of the eye captured by the image capturing unit based on a relationship between positions of the first image and the second image;
• controlling a mouse pointer control unit displayed on the display unit to move within the display unit based on the detected movement amount of the gaze of the eye;
• and
• setting a reference shift amount that is used as a reference for a variation of the position of the first image and the position of the second image;
• wherein the reference shift amount is updated in accordance with movement of the mouse pointer.
