Abstract
The invention is related to a method and system for calibrating an eye tracking device configured to track a gaze point of a user on a display The method comprises: presenting a video on the display to a user, the video having a start size and a start position; tracking the gaze of the user, using an image sensor of the eye tracking device; and sequentially completing, for at least one calibration position, the steps of: resizing the video to a calibration size, wherein the calibration size is smaller than the start size, and translating the video to a calibration position; recording calibration data, using the eye tracking device, for the user viewing the video in the calibration position; and resizing the video to a second size that is greater than the start size.
