Assessment of drowsiness based on ocular parameters detected by infrared reflectance oculography.

ABSTRACT:

Study objectives

Numerous ocular parameters have been proposed as reliable physiological markers of drowsiness. A device that measures many of these parameters and then combines them into a single metric (the Johns Drowsiness Scale [JDS]) is being used commercially to assess drowsiness in professional drivers. Here, we examine how these parameters reflect changes in drowsiness, and how they relate to objective and subjective indices of the drowsy state in a controlled laboratory setting.

Design

A within subject prospective study.

Participants

29 healthy adults (18 males; mean age 23.3 ± 4.6 years; range 18-34 years).

Interventions
