First, subjects filled out a survey to indicate their current and average drowsiness levels. The questions on this survey were determined using drowsiness information that coincided with traffic accidents. Then the subjects' faces were filmed while they perform the following activities: reading a passage, watching a video of a driving simulation, and performing a driving simulation.
The driving simulation involved users driving around in ``freeplay mode'' in Driving Simulator 2013 using Logitech Driving Force G29 Racing Wheel for PlayStation 4 and PlayStation 3.
