This publication details a quantifiable and objective operator drowsiness test. The test takes between 30 seconds to two (2) minutes to be administered. Any smartphone that has a front-facing camera and the supporting software can run the newly-developed and self-administrable test. It leverages years in sleep deprivation research that have found objective correlations between drowsiness (or alertness) and physical and behavioral parameters, such as: gazing, facial features, pupil size, blink rate, blink duration, breathing, pulse, head movements, face skin-tone, speech pattern, and vocal sound. In addition, the mass use of smartphones with rear-facing and front-facing cameras gives researchers the opportunity to deploy this new operator drowsiness test to a wide audience.
