METHOD AND APPARATUS FOR TRACKING GAZE POSITION
First Claim
1. A gaze position tracking apparatus for detecting a user'"'"'s gaze position form a terminal having a display device, comprising:
- an image capturing module for illuminating infrared rays to an user'"'"'s eyes, reflecting an user'"'"'s eye image illuminated by infrared rays (hereinafter, infrared eye image) at 45°
, and capturing the 45°
reflected user'"'"'s eye image; and
an image processing module for obtaining a pupil center point of the infrared eye image by performing a predetermined algorithm, and mapping the pupil center point on a display plane of a display device through a predetermined transform function.

Abstract
A gaze position tracking method and apparatus for simply mapping one'"'"'s gaze position on a monitor screen are provided. The gaze position tracking apparatus includes an image capturing module, and an image processing module. The image capturing module illuminates infrared rays to a user'"'"'s eyes, reflects an illuminated eye image at 45°, and captures the 45° reflected eye image. The image processing module obtains a pupil center point of the illuminated eye image by performing a predetermined algorithm, and maps the pupil center point on a display plane of a display device through a predetermined transform function.
