Filed:

Aug 14, 2002

Appl. No.:

10/219708

Inventors:

Gregory T. Edwards - Roseville CA

Assignee:

The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA

International Classification:

A61B 1300

US Classification:

600558

Abstract:

A computer-implemented method infers mental states of a person from eye movements of the person. The method includes identifying elementary features of eye tracker data, such as fixations and saccades, and recognizing from the elementary features a plurality of eye-movement patterns. Each eye-movement pattern is recognized by comparing the elementary features with a predetermined eye-movement pattern template. A given eye-movement pattern is recognized if the elementary features satisfy a set of criteria associated with the template for that eye-movement pattern. The method further includes the step of recognizing from the eye-movement patterns a plurality of eye-behavior patterns corresponding to the mental states of the person. Because high level mental states of the user are determined in real time, the method provides the basis for reliably determining when a user intends to select a target.

US Classification:

382103, 351209, 600558, 348 78

Abstract:

Eyetracking techniques and analysis techniques are disclosed. At least one interpretation of eyetracking data is received from an eye interpretation engine.
