DRIVING DROWSY
Eye-tracking software used to detect levels of drowsiness, among other measures
Drowsiness alerts: Do they work? A recent study sponsored by the National Highway Traffic Safety Administration (NHTSA) looked at drowsiness during overnight drives of four hours in the NADS-1 simulator. The goal was to look at how drowsiness mitigation tactics—such as a coffee cup alert when the vehicle detects drowsiness in the driver— influence driver decision-making and performance over long drives and the interface design implications of these findings. Simulation drives were held between 2 and 6 a.m., and drivers were given the option to stop and take breaks. Results are being analyzed and prepared for publication.
Eye-tracking software is used to determine drowsiness levels by measuring eye closure and other measures.
