Automation Calibration of Eye Movements & Pupillometry Measurement using Electrooculogram

A method for calibrating eye information includes receiving eye state data measured during a calibration period, receiving head state data measured during the calibration period, calibrating the eye state data based on the head state data, and generating an eye angle measurement based on the calibrated eye state data. Calibrating the eye state data may include correlating the eye state data with the head state data during a period when a vestibulo-ocular reflex occurs. In some implementations, the eye state data may include eye movement data and the head state data may include head movement data. The calibrated eye state data is considered to have improved accuracy and therefore may be used as a more reliable basis for determining a variety of health conditions.
