Abstract
Using a head-mounted eye tracker a new methodology based on homography matrix was developed to determine the subject's point-of-gaze from view-image coordinate to static object coordinate. Homopgraphy matrix is calculated by four or more marked points and point correspondences in view-image. Error analysis is provided by the simulative and real experiments. Both results show that the methodology for determining point-of-gaze is exactness.
