(PhysOrg.com) -- Car manufacturers are looking at a technology that sets off an alarm for drivers if they are falling asleep at the wheel. Sensors embedded in the driver’s headrest would read the brain’s electrical activity pasterns. The sensors would sound an alarm if detecting the driver might nod off. The company with the technology is San Jose-based NeuroSky. The company makes electroencephalography (EEG) headsets and has other technologies that translate brain-signal readings into practical use. The company promotes itself as on a mission to make BCI (brain computer interface) technologies available to any industry, and the auto solution is reported to be in the works.
In theory, developing hardware and software that can understand brain signals and delivering products that translate the information for practical use promise limitless applications. In theory. The traditional use of the EEG (electroencephalogram) in lab and clinical settings has involved reading brain signals by hooking the user up to electrodes applied on the scalp with a thick medical gel to raise the brainwave signal. For widespread use, companies like NeuroSky want to be the ones to deliver brain-signal-reading devices outside the labs into real-life settings.
NeuroSky’s auto application involves gel-free sensors. In the scenario, no headset used for scalp-touching to pick up the brain's signals is involved. The sensors instead work through the headrest’s fabric.

Would Not It Be Nice If You Fell Asleep At The Wheel And Your Car Woke You Up?
Car makers are testing a system that senses brain waves via sensors in the headrest. If you fall asleep, your car would wake you up!
