Challenge

Our Tier 2 Partner needed ground truth dataset for the development of novel driver drowsiness detection algorithms as part of their driver monitoring product. Our team had to combine multiple measures including: driving performance, detailed eye-tracking and physiological data (EEG and ECG) to reference drowsiness levels. As driver drowsiness is a safety-critical state, our team proposed a safe and standardised solution that also enabled to generate relevant dataset.

The Robotec.ai team developed proprietary methodology for collecting and referencing drivers’ drowsiness data while driving using a high-end driving simulator as well as a dedicated EEG and ECG setup. The study was conducted with human drivers from multiple ethnicities and age groups to meet requirements of international automotive standards.

Solution

Methodology of inducing drowsiness through sleep deprivation and accounting for circadian rhythm as well as applying monotonous driving conditions.
Using Robotec.ai proprietary signal processing algorithms for driving performance and physiological data analysis.
Setting up dedicated 500 Hz physiological setup EEG and ECG and constant monitoring of signal quality.
Programming the high-end driving simulator.
Synchronising of multiple data acquisition systems.
