Abstract
A moving object is best recognized by looking with repeated rapid blinks as compared with the usual method of looking. Blinking is associated with the function of the eyelids and oculomotor muscles, retina, optic nerve and cerebrum. Hence, the blink value may be an indication of the total functioning of these organs and the autonomic nervous system.
A method of measuring the blink value is presented, which enables rapid and accurate measurement of fatigue in the whole body.
