Disclosed herein are methods and systems for real-time detection of psychophysiological states from eye movement data. The methods involve capturing eye gaze vectors and eyelid openness levels over time using a user-facing camera. A sequence of discrete eye behaviors, including saccades, fixations, blinks, and long closures, is determined from the eye gaze vectors and eyelid openness levels. The sequence of discrete eye behaviors is transformed into a machine readable representation using a sliding time window. A mathematical or machine learning model then maps the machine readable representation of eye behaviors to one or more psychophysiological states. This approach provides a computationally efficient mechanism for predicting psychophysiological states by compressing gaze data into a continuous, numerical representation of eye behavioral events correlated with human psychophysiological states, including drowsiness, cognitive load, stress, and others.
