Abstract

Gaze based systems and methods are used to monitor the attention of a user. One or more images are displayed to a user on a display. It is determined that an image of the one or more images is being viewed by an eye of the user from one or more measurements received from an eyetracker. One or more modifications to the image are displayed on the display over time so as to maintain the attention of the user. Whether or not the attention of the user is maintained is determined from one or more additional measurements received from the eyetracker after the one or more modifications to the image. In various embodiments, the one or more modifications to the image include moving the image on the display. In various embodiments, the one or more modifications to the image include animating the image on the display.

Claims

1. A system for monitoring the attention of a user, comprising

a display;

an eyetracker that measures a user'"'"'s gazepoint within the display; and

a processor in communication with the display and the eyetracker that

displays one or more images to the user on the display;

determines that an image of the one or more images is being viewed by an eye of the user from one or more measurements received from the eyetracker;

displays one or more modifications to the image on the display over time so as to maintain the attention of the user; and

determines if the attention of the user is maintained from one or more additional measurements received from the eyetracker after the one or more modifications to the image.

2. The system of claim 1, wherein the processor determines that an image of the one or more images is being viewed by an eye of the user from one or more measurements received from the eyetracker by receiving from the eyetracker a first gazepoint of the eye on the display and calculating the image that includes the first gazepoint.

3. The system of claim 2, wherein the processor displays one or more modifications to the image on the display over time so as to maintain the attention of the user by displaying the image at a new location on the display so that the image does not include the location of the first gazepoint.

4. The system of claim 2, wherein the processor determines if the attention of the user is maintained from one or more additional measurements received from the eyetracker after the one or more modifications to the image by receiving from the eyetracker a second gazepoint of the eye on the display after the image is modified and calculating if image includes the second gazepoint.

5. The system of claim 1, wherein the processor displays one or more modifications to the image on the display over time so as to maintain the attention of the user by animating the image on the display.

6. The system of claim 5, wherein the processor further increases the activity of the animation if the attention of the user is maintained.

7. The system of claim 5, wherein the processor further decreases the activity of the animation if the attention of the user is not maintained.

8. The system of claim 1, wherein the processor displays one or more modifications to the image on the display over time so as to maintain the attention of the user by increasing the complexity of the image on the display.

9. The system of claim 1, wherein the one or more modifications comprise at least two modifications.

10. The system of claim 1, wherein the processor displays another modification to the image on the display that encourages a response from an input device after the one or more modifications and determines that the user'"'"'s attention is maintained, if the response from the input device is received.

11. The system of claim 10, wherein the input device comprises a keyboard, a mouse, a head point, a finger pointer, or a microphone.

12. The system of claim 1, wherein the image is a character with one or more eyes.

13. The system of claim 1, wherein the image is an eye of a character with one or more eyes.

14. The system of claim 13, wherein the processor displays one or more modifications to the image on the display over time so as to maintain the attention of the user by displaying the eye of the character as making eye contact with the eye of the user.

15. The system of claim 1, further comprising a second display that allows a teacher to monitor activities of the display and the eyetracker.

16. The system of claim 15, further comprising an input device that allows the teacher to modify the image.

17. The system of claim 1, further comprising a memory in communication with the processor that the processor uses to record the one or modifications, the one or more measurements, the one or more additional measurements, and a rate of presentation of the one or modifications to the user.

18. The system of claim 17, wherein the processor displays the one or more modification to the user based on a rate of presentation previously stored in the memory.

19. A method for monitoring the attention of a user, comprising displaying one or more images to a user on a display;

determining that an image of the one or more images is being viewed by an eye of the user from one or more measurements received from an eyetracker;

displaying one or more modifications to the image on the display over time so as to maintain the attention of the user; and

determining if the attention of the user is maintained from one or more additional measurements received from the eyetracker after the one or more modifications to the image.

20. A computer program product, comprising a tangible computer-readable storage medium whose contents include a program with instructions being executed on a processor so as to perform a method for monitoring the attention of a user, the method comprising:

providing a system, wherein the system comprises distinct software modules, and wherein the distinct software modules comprise a display module and as eyetracking module;

displaying one or more images to a user on a display using the display module;

determining that an image of the one or more images is being viewed by an eye of the user from one or more measurements received from an eyetracker using the eyetracking module;

displaying one or more modifications to the image on the display over time so as to maintain the attention of the user using the display module; and

determining if the attention of the user is maintained from one or more additional measurements received from the eyetracker after the one or more modifications to the image using the eyetracking module.
