Abstract
A system and method for determining a subject's level of fatigue. The method includes measuring microsaccadic eye movement dynamics of the subject, calculating a current microsaccade peak velocity from the measured microsaccadic eye movement dynamics, and comparing the current microsaccade peak velocity to a baseline microsaccade peak velocity. The method further includes determining the level of fatigue based on a difference between the current microsaccade peak velocity and the baseline microsaccade peak velocity.
Claims6
A method for determining a subject's level of fatigue, the method comprising the steps of:
- measuring microsaccadic eye movement dynamics of the subject;
- calculating a current microsaccade peak velocity from the measured microsaccadic eye movement dynamics;
- comparing the current microsaccade peak velocity to a baseline microsaccade peak velocity;
- and
- determining the level of fatigue based on a difference between the current microsaccade peak velocity and the baseline microsaccade peak velocity.
A system for determining a subject's level of fatigue, the system comprising:
- a system configured to receive a measure of microsaccadic eye movement dynamics of the subject;
- a computer readable storage medium having stored thereon instructions that, when executed by a computer processor, cause the processor to:
- determine, using the measure of microsaccadic eye movement dynamics of the subject, a current microsaccade peak velocity;
- compare the current microsaccade peak velocity to a stored baseline microsaccade peak velocity;
- and
- generate a report indicating the subject's level of fatigue based on a difference between the current microsaccade peak velocity and the stored baseline microsaccade peak velocity.
