A.J. Tucker, M.W. Johns. The Duration of Eyelid Movements During Blinks: Changes with Drowsiness.
Introduction
The increased duration of spontaneous blinks has been suggested as an early indicator of the drowsy state (Caffier, Erdmann, & Ullsperger, 2003). Blinks have been monitored traditionally by the EOG, video images or magnetic search coils on the eyelids (Evinger, Manning, & Sibony, 1991). A new infrared (IR) reflectance method was used here to measure the duration of each component of blinks (eyelids closing, remaining closed and reopening) when subjects were alert and when drowsy.
