Wearable eye tracking system

Abstract

There is provided a method and wearable eye-tracking device for determining a fatigue level of a user, the method comprising the steps of acquiring two channels of an observed EEG (electro-encephalogram) signal using a plurality of silver chloride (AgCl) electrodes positioned in contact with and around the user's ear, obtaining user's inputs for a plurality of psychological questions and calculating an evaluation metric, decomposing the observed EEG signal using filter and blind signal separation techniques into a plurality of features, classifying and converting the plurality of features in combination with the calculated evaluation metric to a fatigue level using a classification algorithm and fuzzy logic and outputting the obtained fatigue level along with customized prompts to the user through visual and audio signals for preventing an accident.
