Patent Images
1. An eye-tracking method, comprising the steps of:
- generating an image in which a selected foveated region is more focused than the balance of the image;
displaying the generated image to a user;
tracking movements of the user'"'"'s head;
changing the area of the image which mirrors user eye movement and is in-focus relative to the balance of the image as a function of the user'"'"'s head movements to obtain information about the image;
recording the movements of the position of the in-focus area on the display screen while acquiring information from the image; and
using combined head movement data and eyetracking or EOG derived data to control the foveated region.

Abstract
A system for detecting and recording eye-tracking data by presenting to an observer a display image with an area in focus surrounded by blurred areas. The observer may shift the focus area within the image by head movements which are wirelessly transmitted to a receiver and used to modify the displayed image. This system solves that part of the eye-tracking problem that is most critical for measuring cognitive processes.
