Harman demonstrates pupil-based driver monitoring system
05 January 2016
Demonstrated at the CES 2016 show, Harman’s eye and pupil tracking technology improves driver safety by continuously monitoring cognitive load.
New technology unveiled by Harman International Industries measures increases in pupil dilation as an indication of a driver’s mental workload. The eye and pupil tracking system measures high cognitive load and mental multi-tasking in the driver’s seat, and signals the car’s other safety systems to adapt to the driver’s state.
Adoption of in-cabin cameras is growing rapidly, enabling features such as occupant detection and driver drowsiness monitoring. With the introduction of high cognitive load detection, Harman’s eye and pupil tracking technology brings additional value to the driver-facing camera. The technology eliminates the need for complex sensors built into seats and steering wheels, or biometric sensors that require physical contact with the driver.
The camera continually captures the driver’s pupil dilation, and a proprietary software algorithm analyses the pupil reflex using advanced filtering and signal processing. The filter isolates and identifies responses triggered by high cognitive load. The calculated outputs are used to adjust user interfaces, like placing mobile devices in do-not-disturb mode or adjusting ADAS system intervention thresholds to minimise physical and mental distraction to the driver.
