Automotive Research

Conventional driver monitoring systems rely on indirect methods such as steering movements or eyelid tracking. EEG-based systems detect fatigue and inattention directly from brain signals, in real time, long before behavioural signs appear.

g.Nautilus Research delivers high-quality EEG under the vibration and motion of a vehicle. g.tec's own catalogue lists the “Automotive/Aerospace Neurophysiology Lab” as a dedicated lab set-up. It covers a wide range of applications, from the flight simulator to real vehicle tests and the high-acceleration simulator.

Fatigue shows in EEG as increased power in the theta and alpha bands. g.tec's wearable EEG system monitors the driver's brain activity continuously in the vehicle and detects these changes in real time. A warning system can step in before behavioural signs appear.

EEG-based fatigue detection gives much earlier and more reliable results than indirect methods such as blinking or steering movements. Monitoring driver attention, drowsiness and cognitive load with millisecond precision has become the core method of in-vehicle neuroergonomics research.

g.Nautilus Research is suited to EEG recording for pilots and astronauts in aircraft cockpits, flight simulators and high-acceleration simulators. Spatial disorientation is a major cause of aviation accidents; monitoring the pilot's brain activity with EEG allows disorientation to be detected early.

Pilot cognitive load, distraction and stress are measured objectively with EEG in complex flight scenarios. Because g.SAHARA hybrid active electrodes need no hair washing, they allow a quick set-up in operational aviation settings.

Working together with eye trackers and video cameras, g.Nautilus Research forms a complete platform for in-vehicle neuroergonomics research. Where the driver looks, for how long, and the brain activity at that moment are recorded simultaneously.

With the body sensor support of g.Nautilus Multi-purpose, ECG (heart rhythm), GSR (skin conductance) and respiration can be monitored alongside EEG. This multichannel physiological profile is used to assess driver stress management, HMI (human-machine interface) design and autonomous-vehicle takeover scenarios.
