First Claim
Patent Images
1. A system for recording eye movements necessary for a user to acquire information from an image, comprising:
- a display screen;
an image generator operative to generate an image on the display screen with a first portion in-focus and other portions blurred with respect to the first portion;
a transmitter attached to the user'"'"'s head;
a receiver for detecting signals from the transmitter relating to motion of the user'"'"'s head;
circuitry for providing the motion signals to the display generator to control the region of the generated image which is in-focus as a function of the head movements; and
a recorder to record the in-focus positions on the display screen.

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.

4. 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; and
changing the area of the image which 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. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
