Abstract
A method of calibrating an eye-tracking system for use with a camera, wherein in use the eye-tracking system obtains a plurality of images of a user's eye from the camera, uses a normalisation process to convert the images to a normalised image space based on at least one intrinsic property of the camera, and uses a gaze determination process to determine an estimate of the gaze of the user's eye based on the normalised images.
