Physiological signals were commonly used to detect drowsiness, but this approach was only practical in a laboratory environment as it required the study and calibration of individual subjects. The report also stated that in-vehicle approaches were under investigation, including monitoring of eye-closure, steering sensors, and lane tracking (NHTSA, 1998). However, limitations in available technologies meant that these systems were only available in commercial vehicles at the time.
